Psychology as a Science of the Soul: Evangelos Christou's The Logos of the Soul (1963).

After Evangelos Christou (1923-1956) studied philosophy at King's College, Cambridge, with Wittgenstein and others, he earned a doctorate at the Jung Institute in Zürich. He then returned home to Alexandria, near which he died in a car crash. The Logos of the Soul, published posthumously, argued for a psychology that would be neither a natural scientific psychology, devoted to causal analyses, nor a philosophical discipline that analysed mental events. Psychology would be an autonomous science of the soul, an unknown distinct from body and mind. Science deals with bodies and behaviours; philosophy with the mental concepts and acts. Psychology deals with "psychological experience". Dreams and fantasies can be sources of psychological experience, but so can perceptual acts and mental acts. Meaning occurs when something encounters an ego or self in a psychological experience. Observation in psychology is participant observation, akin to witnessing of a drama. Psychological methods, such as psychotherapy, are both means of discovery and means of becoming. Christou's work brought together Jung's analytical psychology and mid-century British philosophy in order to stake out the ground for psychology that would be an empirical analysis of psychological experience and a logical analysis of the concepts used in that psychology.

Après qu'Evangelos Christou (1923­1956) ait étudié la philosophie au King's College à Cambridge, avec Wittgenstein et d'autres, il fit un doctorat à l'Institut Jung de Zurich. Il retourna ensuite à Alexandrie, où il mourut peu de temps après dans un accident de voiture. The Logos of the Soul, publié à titre posthume, plaide pour une psychologie qui ne serait ni une psychologie scientifique naturelle, dédiée aux analyses causales, ni une discipline philosophique qui analyse les événements du mental. La psychologie serait une science autonome de l'âme, une inconnue distincte du corps et du mental. La science traite des corps et des comportements; la philosophie s'occupe des concepts et des actes. La psychologie s'intéresse à « l'expérience psychologique ¼. Les rêves et les fantasmes peuvent être des sources d'expérience psychologique, mais il en est de même pour les actes de perception et les actes du mental. Le sens apparait quand quelque chose rencontre un moi ou un soi dans une expérience psychologique. L'observation en psychologie est une observation participative, qui s'apparente à être témoin d'une pièce dramatique. Les méthodes psychologiques, telles la psychothérapie, sont à la fois des moyens d'exploration et des moyens pour devenir. L'œuvre de Christou a relié la psychologie analytique de Jung et la philosophie britannique du milieu du siècle afin de revendiquer le terrain pour une psychologie qui serait une analyse empirique de l'expérience psychologique et une analyse logique des concepts utilisés dans cette psychologie.

Luego de estudiar filosofía en el King's College de Cambridge, con Wittgenstein y otros, Evangelos Christou (1923­1956) obtuvo un doctorado en el Instituto Jung de Zúrich. Posteriormente regresó a su casa en Alejandría, cerca de la cual murió en un accidente de auto. El Logos del alma, publicado póstumamente, abogaba por una psicología que no fuera ni una psicología científica natural, dedicada a los análisis causales, ni una disciplina filosófica que analizara los acontecimientos mentales. La psicología sería una ciencia autónoma del alma, lo desconocido distinto del cuerpo y de la mente. La ciencia se ocupa de los cuerpos y las conductas; la filosofía, de los conceptos y los actos mentales. La psicología se ocupa de la "experiencia psicológica". Los sueños y las fantasías pueden ser fuentes de experiencia psicológica, pero también los actos perceptivos y mentales. El sentido se produce cuando algo se encuentra con un ego o un self en una experiencia psicológica. La observación en psicología es una observación participante, similar a ser testigo de un drama. Los métodos psicológicos, como la psicoterapia, son a la vez medios de descubrimiento y medios de devenir. La obra de Christou reunió la psicología analítica de Jung y la filosofía británica de mediados de siglo para sentar las bases de una psicología que fuera un análisis empírico de la experiencia psicológica y un análisis lógico de los conceptos utilizados en esa psicología.

Ame-miR-1-3p of bee venom reduced cell viability through the AZIN1/OAZ1-ODC1-polyamines pathway and enhanced the defense ability of honeybee (Apis mellifera L.).

Bee venom serves as an essential defensive weapon for bees and also finds application as a medicinal drug. MicroRNAs (miRNAs) serve as critical regulators and have been demonstrated to perform a variety of biological functions. However, the presence of miRNAs in bee venom needs to be confirmed. Therefore, we conducted small RNA sequencing and identified 158 known miRNAs, 15 conserved miRNAs and 4 novel miRNAs. It is noteworthy that ame-miR-1-3p, the most abundant among them, accounted for over a quarter of all miRNA reads. To validate the function of ame-miR-1-3p, we screened 28 candidate target genes using transcriptome sequencing and three target gene prediction software (miRanda, PITA and TargetScan) for ame-miR-1-3p. Subsequently, we employed real-time quantitative reverse transcription PCR (qRT-PCR), Western blot and other technologies to confirm that ame-miR-1-3p inhibits the relative expression of antizyme inhibitor 1 (AZIN1) by targeting the 3' untranslated region (UTR) of AZIN1. This, in turn, caused ODC antizyme 1 (OAZ1) to bind to ornithine decarboxylase 1 (ODC1) and mark ODC1 for proteolytic destruction. The reduction in functional ODC1 ultimately resulted in a decrease in polyamine biosynthesis. Furthermore, we determined that ame-miR-1-3p accelerates cell death through the AZIN1/OAZ1-ODC1-polyamines pathway. Our studies demonstrate that ame-miR-1-3p diminishes cell viability and it may collaborate with sPLA2 to enhance the defence capabilities of honeybees (Apis mellifera L.). Collectively, these data further elucidate the defence mechanism of bee venom and expand the potential applications of bee venom in medical treatment.

Benign Adenomyoepithelioma of the Breast: A Case Report and Review of Imaging Features.

Adenomyoepithelioma (AME) of the breast is a rare tumor that can be benign or malignant and has varied morphological features. We report a case of a 62-year-old female with a history of right breast cancer who presented with abnormal screening mammography. The detection, presentation, and varied imaging characteristics of AMEs are discussed. The nonspecific imaging and histologic appearance of AME are highlighted, emphasizing the need for representative biopsy samples and histopathological review for diagnosis. Our case underlines the importance of wide surgical excision with negative margins in the presence of diagnostic uncertainty, which corresponds with the current recommended treatment for AME to prevent recurrence.

Apparent mineralocorticoid excess in Israel: a case series and literature review.

BACKGROUND AND OBJECTIVE: Apparent mineralocorticoid excess (AME) syndrome is an ultra-rare autosomal-recessive tubulopathy, caused by mutations in HSD11B2, leading to excessive activation of the kidney mineralocorticoid receptor, and characterized by early-onset low-renin hypertension, hypokalemia, and risk of chronic kidney disease (CKD). To date, most reports included few patients, and none described patients from Israel. We aimed to describe AME patients from Israel and to review the relevant literature. DESIGN: Retrospective cohort study. METHODS: Clinical, laboratory, and molecular data from patients' records were collected. RESULTS: Five patients presented at early childhood with normal estimated glomerular filtration rate (eGFR), while 2 patients presented during late childhood with CKD. Molecular analysis revealed 2 novel homozygous mutations in HSD11B2. All patients presented with severe hypertension and hypokalemia. While all patients developed nephrocalcinosis, only 1 showed hypercalciuria. All individuals were managed with potassium supplements, mineralocorticoid receptor antagonists, and various antihypertensive medications. One patient survived cardiac arrest secondary to severe hyperkalemia. At last follow-up, those 5 patients who presented early exhibited normal eGFR and near-normal blood pressure, but 2 have hypertension complications. The 2 patients who presented with CKD progressed to end-stage kidney disease (ESKD) necessitating dialysis and kidney transplantation. CONCLUSIONS: In this 11-year follow-up report of 2 Israeli families with AME, patients who presented early maintained long-term normal kidney function, while those who presented late progressed to ESKD. Nevertheless, despite early diagnosis and management, AME is commonly associated with serious complications of the disease or its treatment.

Microalbuminuria in Rats Treated with D-Nitroarginine Methyl Ether.

Microalbuminuria is an early symptom and prognostic marker of the progression of renal pathology. The analysis of the role of anionic components of the renal glomeruli in the albumin retention and the development of a model of minimal changes in the glomerular filter leading to the appearance of microalbuminuria are relevant. The effect of organic cations D-arginine methyl esters (D-AME) and D-nitroarginine (D-NAME) on the excretion of albumin by the kidneys in rats was studied. D-AME had no effect on urinary albumin excretion in rats. D-NAME caused microalbuminuria, which persisted for more than a day and sharply increased after injection of vasopressin. The number of anionic sites labeled with polyethyleneimine decreased in the structures of the glomerular filter. D-NAME-induced microalbuminuria can later serve as a model for studying nephroprotective or damaging factors.

Jung's Erotic Phenomenology: I. A New Translation.

In the introduction to The Psychology of the Transference (1946), Carl Jung sketched out a theory of "erotic phenomenology" which condenses his teaching about sexuality and romantic love into a very concise summary. But the meaning of this passage is obscured in the English translation given in the Collected Works of C. G. Jung. I propose here a new translation which makes Jung's meaning clearer, along with a commentary which explains it in the context of Freudian drive theory and German 19th century philosophy. Invoking the concepts of instinct, mind, and Eros (both the passion and the divine figure), Jung's theory says that male sexual desire can be cultivated or repressed in four distinct ways, each associated with a female symbolic figure or anima image: Eve, Helen, Mary and Sophia.

Dans son introduction à La Psychologie du Transfert (1946), Carl Jung esquisse une « phénoménologie érotique ¼ qui condense ses enseignements sur la sexualité et le désir en un résumé très concis. Mais le sens de ce passage est brouillé dans la traduction anglaise des Collected Works of C.G. Jung. Je propose ici une nouvelle traduction qui rend l'argument de Jung plus clair, suivie d'un commentaire qui l'explique dans le contexte de la théorie freudienne des pulsions et de la philosophie allemande du XIXe siècle. Invoquant les concepts d'instinct, d'esprit et d'Eros (en tant que passion ainsi que figure divine), la théorie de Jung dit que le désir sexuel masculin peut être cultivé ou réprimé de quatre manières distinctes, chacune associée à une figure symbolique féminine ou image de l'anima: Eve, Hélène, Marie et Sophia.

En la introducción a La Psicología de la Transferencia (1946), Carl Jung esbozó una "fenomenología erótica" que condensa sus enseñanzas sobre la sexualidad y el amor romántico en un resumen muy conciso. Pero el significado de este pasaje queda opacado en la traducción inglesa de las Obras Completas de C.G. Jung. Propongo aquí una nueva traducción que aclara el significado de Jung, junto con un comentario que lo explica en el contexto de la teoría freudiana de la pulsión y la filosofía alemana del siglo XIX. Invocando los conceptos de instinto, mente y Eros (tanto la pasión como la figura divina), la teoría de Jung expresa que el deseo sexual masculino puede cultivarse o reprimirse de cuatro maneras distintas, cada una asociada a una figura simbólica femenina o imagen del ánima: Eva, Helena, María y Sofía.

Effect of dietary ß-mannanase supplementation on broiler performance.

This study was conducted to investigate the effect of graded levels of ß-mannanase supplementation in broiler diets on growth performance, energy digestibility, and lesion scores in d-old birds fed mash, corn-soybean meal-based diets and raised to 42 d. Five dietary treatments were investigated: 1) positive control diet (PC) containing standard energy; 2) negative control (NC) with 100 kcal/kg diet reduction in AME compared to PC; 3) NC supplemented with 30 U/g ß-mannanase (NC + 30 U); 4) NC supplemented with 60 U/g ß-mannanase (NC + 60 U); and 5) NC supplemented with 90 U/g ß-mannanase (NC + 90 U). Each treatment had 6 replicate pens with 52 chicks per replicate. Data was analyzed using 1-way ANOVA, and means were separated by LSMEANS. Reduction of 100 kcal/kg feed (NC) resulted in an overall body weight gain reduction of 51 g (P < 0.05) and feed conversion loss of approximately 4 points (P < 0.05) compared to PC at 42 d of age. At the same time, supplementing ß-mannanase at 60 and 90 U/g improved growth performance parameters compared to NC, while 30 U/g did not result in significant improvements beyond NC; body weight gain was improved (P < 0.05) by 87, and 106 g when ß-mannanase was supplemented at 60 and 90 U/g, respectively, compared to NC. This corresponded to an improvement by 6 and 7 points in feed conversion for 60 and 90 U/g supplementation, respectively, compared to NC. Furthermore, AMEn was improved (P < 0.05) by 15, 97, and 116 kcal/kg at 42 d when ß-mannanase was added to NC at 30, 60, and 90 U/g, respectively. Digesta viscosity measured at 42 d was decreased (P < 0.05) by ß-mannanase supplementation of 60 and 90 U/g, compared to NC, while 42 d lesion scores were improved (P < 0.05) by ß-mannanase supplementation compared to NC. Data demonstrated that dietary supplementation of ß-mannanase improved growth performance, energy digestibility, and reduced viscosity and lesion scores when supplemented with diets with a reduced energy content of 100 kcal/kg compared to a standard energy diet.

MicroRNA ame-let-7 targets Amdop2 to increase sucrose sensitivity in honey bees (Apis mellifera).

BACKGROUND: As an important catecholamine neurotransmitter in invertebrates and vertebrates, dopamine plays multiple roles in the life of the honey bee. Dopamine receptors (DA), which specifically bind to dopamine to activate downstream cascades, have been reported to be involved in honey bee reproduction, division of labour, as well as learning and motor behaviour. However, how dopamine receptors regulate honey bee behavior remains uninvestigated. RESULTS: The expression level of Amdop2 in the brain increased with the age of worker bees, which was just the opposite trend of ame-let-7. Inhibition of ame-let-7 through feeding an inhibitor upregulated Amdop2 expression; conversely, overexpression of ame-let-7 through a mimic downregulated Amdop2. Moreover, knockdown of Amdop2 in forager brain led to significantly higher sucrose responsiveness, which is similar to the phenotype of overexpression of ame-let-7. Finally, we confirmed that ame-let-7 directly targets Amdop2 in vitro by a luciferase reporter assay. CONCLUSIONS: ame-let-7 is involved in the dopamine receptor signaling pathway to modulate the sucrose sensitivity in honey bees. Specifically, it down-regulates Amdop2, which then induces higher responses to sucrose. These results further unraveled the diverse mechanisms of the dopamine pathway in the regulation of insect behavior.

Exposure to sublethal concentrations of thiacloprid insecticide modulated the expression of microRNAs in honeybees (Apis mellifera L.).

This study aimed to investigate the sublethal effects of thiacloprid on microRNA (miRNA) expression in honeybees (Apis mellifera L.) and the role of a specific miRNA, ame-miR-283-5p, in thiacloprid resistance. The high-throughput small RNA-sequencing was used to analyze global miRNA expression profile changes in honeybees orally exposed to sublethal concentrations of thiacloprid (20 mg/L and 4 mg/L) for 72 h. Thiacloprid at 20 mg/L had no observed adverse effects. In addition, bees were fed with miRNA mimics or inhibitors to increase or decrease ame-miR-283-5p expression, and its effects on P450 gene expression (CYP9Q2 and CYP9Q3) were examined. Thiacloprid susceptibility was also detected. The results showed that treatment with thiacloprid at 20 mg/L and 4 mg/L induced 11 and five differentially expressed miRNAs (DEMs), respectively. Bioinformatic analysis suggested that the DEMs are mainly involved in the regulation of growth and development, metabolism, nerve conduction, and behavior. ame-miR-283-5p was downregulated by both concentrations, which was validated using quantitative real-time reverse transcription PCR analysis. Enhancing ame-miR-283-5p expression significantly inhibited CYP9Q2 mRNA and protein expression, and increased thiacloprid toxicity, while reducing ame-miR-283-5p expression significantly promoted CYP9Q2 expression, and decreased thiacloprid susceptibility. Our study revealed a novel role of miRNAs in insecticide resistance in honeybees.

Ame-miR-980-3p participates in autophagy-mediated midgut remodelling in Apis mellifera via targeting Atg2B.

Autophagy is a process that serves to degrade damaged proteins and organelles, thereby promoting cell homeostasis, differentiation, development and survival. Many miRNAs have been found to have regulatory roles in autophagy. In insects, it has been shown that autophagy is involved in hormone-regulated programmed cell death during metamorphic midgut remodelling. However, whether this is also true during the remodelling of the honey bee midgut is unclear. In the present study, we explored the relationship between autophagy and midgut remodelling and sought to identify miRNAs involved in this physiological process. We found that autophagy occurred during midgut remodelling and that the inhibition of autophagy resulted in midgut dysplasia in prepupae. Differentially expressed miRNAs enriched in the autophagy signalling pathway during midgut remodelling were identified by small RNA-seq. Ame-miR-980-3p, which targets the autophagy-related gene Atg2B, was screened out. Furthermore, abnormal expression of ame-miR-980-3p in the pupal stage led to the thinning of the midgut wall of newly emerged bees (NE). When ame-miR-980-3p expression was inhibited, the intestinal villi of NE bees became significantly shorter and sparse, and the lipid signal in the peritrophic matrix of Pb almost disappeared, indicating that the adult midgut was underdeveloped and the lipid absorption ability was weakened. Taken together, ame-miR-980-3p targeted Atg2B to participate in the regulation of midgut autophagy in the pupae, and the abnormal expression of ame-miR-980-3p would interfere with cell proliferation and death in the process of midgut remodelling, hinder the formation of adult midgut and eventually lead to adult midgut dysplasia and affect the lipid absorption function of the midgut in Apis mellifera.

Concurrence of Adenomyoepithelioma of the Breast and Gastrointestinal Stromal Tumor of the Stomach: A Case Report and Review of the Literature.

Adenomyoepithelioma (AME) of the breast and gastrointestinal stromal tumors (GISTs) are rare benign (primarily) tumors observed in the breast and gastrointestinal tract, respectively. The coexistence of both of these rare tumors is extremely rare; therefore, the author describes the clinical presentation and pathophysiological findings of such a unique case in this study. A 56-year-old female patient with no medical history presented with a substantial right breast lump, severe nausea, and vomiting, and suffered from iron deficiency anemia. Radiological observation and a right breast excisional biopsy diagnosed the patient with AME associated with ductal carcinoma in situ (DCIS). Endoscopy and a CT scan of the stomach revealed the existence of GIST. This is the first reported case of concurrence of a huge mass of AME and GIST in a patient. Histological and immunohistochemistry tests using p63, SMA, calponin, and Ki67 markers for the breast tumor and DOG-1, CD34, and CD117 markers for the gastric tumor revealed the non-invasive benign state. The patient had a right breast mastectomy with a negative resection margin. AME of the breast and GIST pose diagnostic challenges due to their erratic morphological characteristics and can cause misinterpretation drawn solely from radiological tests. Effective and accurate diagnostics require assessing the histological and immunohistochemistry findings of the tumor to identify the invasiveness of the neoplasm and the associated risk levels. This report, thus, creates awareness among clinicians and pathologists for the consideration of such possibilities and, therefore, conducts the necessary diagnostics and prophylactic treatments.

Anterior meniscus extrusion is associated with anterior tibial osteophyte width in knee osteoarthritis - The Bunkyo Health Study.

Background: In knee osteoarthritis (OA), medial meniscus extrudes both medially and anteriorly. We reported that full-length width of medial tibial osteophyte, which comprises cartilage and bone parts, is directly associated with medial meniscus extrusion in early-stage knee OA and hypothesized that anterior tibial osteophyte (ATO) is also associated with anterior meniscus extrusion (AME). Thus, we aimed to examine their prevalence and relationship. Methods: Elderly subjects (638 females and 507 males; average 72.9 years old) in the Bunkyo Health Study cohort were enrolled. MRI-detected OA changes were evaluated according to the Whole Organ Magnetic Resonance Imaging Score. ATO was evaluated using the method which can assess both cartilage and bone parts of osteophyte by pseudo-coloring images of proton density-weighted fat-suppressed MRI. Results: Most subjects showed the Kellgren-Lawrence grade 1/2 of the medial knee OA (88.1%), AME (94.3%, 3.7 â€‹± â€‹2.2 â€‹mm), and ATO (99.6%, 4.2 â€‹± â€‹1.5 â€‹mm). Among the OA changes, AME was most closely associated with full-length width of ATO (multivariable ߠ​= â€‹0.877, p â€‹< â€‹0.001). The area under the receiver operating characteristic curve for determining the presence of AME as evaluated by ATO width was 0.75 (95% confidence interval 0.60-0.84, p â€‹< â€‹0.001). The odds ratio for the presence of AME as evaluated by ATO width at 2.9 â€‹mm was 7.16 (4.23-12.15, p â€‹< â€‹0.001, age, gender, BMI, and K-L adjusted). Conclusions: AME and ATO were inevitably observed in the elderly subjects and AME was closely associated with full-length width of ATO. Our study provides the first evidence on the close relationship between AME and ATO in knee OA.

The MicroRNA Ame-Bantam-3p Controls Larval Pupal Development by Targeting the Multiple Epidermal Growth Factor-like Domains 8 Gene (megf8) in the Honeybee, Apis mellifera.

20-Hydroxyecdysone (20E) plays an essential role in coordinating developmental transitions in insects through responsive protein-coding genes and microRNAs (miRNAs). However, the interplay between 20E and miRNAs during insect metamorphosis is unknown. In this study, using small RNA sequencing, a comparative miRNA transcriptomic analysis in different development stages, and 20E treatment, we identified ame-bantam-3p as a key candidate miRNA involved in honeybee metamorphosis. Target prediction and in vitro dual-luciferase assays confirmed that ame-bantam-3p interacts with the coding region of the megf8 gene and promotes its expression. Meanwhile, temporal expression analysis revealed that the expression of ame-bantam-3p is higher in the larval stage than in prepupal and pupal stages, and that this expression pattern is similar to that of megf8. In vivo, we found that the mRNA level of megf8 was significantly increased after the injection of ame-bantam-3p agomir. A 20E feeding assay showed that 20E downregulated the expression of both ame-bantam-3p and its target gene megf8 on larval days five, six, and seven. Meanwhile, the injection of ame-bantam-3p agomir also reduced the 20E titer, as well as the transcript levels of essential ecdysteroid synthesis genes, including Dib, Phm, Sad, and Nvd. The transcript levels of 20E cascade genes, including EcRA, ECRB1, USP, E75, E93, and Br-c, were also significantly decreased after ame-bantam-3p agomir injection. However, ame-bantam-3p antagomir injection and dsmegf8 injection showed the opposite effect to ame-bantam-3p agomir injection. Ame-bantam-3p agomir treatment ultimately led to mortality and the failure of larval pupation by inhibiting ecdysteroid synthesis and the 20E signaling pathway. However, the expression of 20E signaling-related genes was significantly increased after megf8 knockdown, and larvae injected with dsmegf8 showed early pupation. Combined, our results indicate that ame-bantam-3p is involved in the 20E signaling pathway through positively regulating its target gene megf8 and is indispensable for larval-pupal development in the honeybee. These findings may enhance our understanding of the relationship between 20E signaling and small RNAs during honeybee development.

Soul, Myth and Cosmovision in a Changing World: Essentials of Analytical Psychology and the Descendent Path.

This essay addresses the key role of analytical psychology amid our changing world: to work towards an expansion of Humanity's worldview. In current times of utmost transformation, it becomes imperative that we embrace a total cosmovision, one that includes the 360 degrees of existence: not only the 180 diurnal degrees of ascent, light and order, yet also the descendent sphere, incorporating what is unconscious, nocturnal and mysterious. Integrating this lower realm in our psychic life, however, contrasts our Western worldview, in which these two domains are seemingly opposed and mutually excluding. Mythopoetic language, and the mythologems that manifest in different myths, provide the means of delving into the profound paradoxes at the core of the total cosmovision. Myths such as Añañuca (Chile), Osiris (Egypt), Dionysus (Greece) and Innana (Sumer), highlight the descending path, providing a symbolic narrative of an archetypical transformation or spin, a key moment of "turning on its own axis" that merges the realms of Life and Death, ascent and descent, birth and decay. To live this paradoxical and generative path of transformation, individuals must seek their personal myth not outside but within themselves, where springs the Suprasense.

Cet article étudie le rôle clé de la psychologie analytique dans notre monde en transformation: travailler à l'expansion de la vision du monde de l'humanité. Dans la période actuelle pleine de transformations radicales il devient essentiel d'avoir une cosmovision globale, qui inclue les 360 degrés de l'existence; non seulement les 180 degrés diurnes de l'ascension, de la lumière et de l'ordre, mais également la sphère descendante qui incorpore ce qui est inconscient, nocturne et mystérieux. L'intégration de ce royaume inférieur dans notre vie psychique, cependant, est en contraste avec la vision occidentale sur le monde, dans laquelle ces deux domaines sont considérés comme opposés et s'excluant mutuellement. Le langage mytho-poétique et les mythologèmes repérables dans les différents mythes fournissent les moyens de pénétrer dans les profonds paradoxes au noyau de la cosmovision totale. Les mythes tels ceux d'Ananuca (Chili), d'Osiris (Egypte), de Dionysos (Grèce), et d'Inanna (Sumer) montrent la voie descendante et offrent le récit symbolique d'une transformation archétypale, ou rotation, un moment clé de 'retournement sur son propre axe' qui fait fusionner les royaumes de Vie et de Mort, d'ascension et de descente, de naissance et de décomposition. Afin de vivre ce chemin de transformation paradoxal et fertile les personnes doivent chercher leur mythe personnel non pas à l'extérieur d'elles-mêmes mais à l'intérieur, d'où jaillit le Suprasens.

El presente artículo aborda el papel clave de la psicología analítica en medio de nuestro mundo cambiante: trabajar hacia una expansión de la cosmovisión de la humanidad. En los tiempos actuales de máxima transformación, se hace imperativo que abracemos una cosmovisión total, que incluya los 360 grados de la existencia: no sólo los 180 grados diurnos de ascenso, luz y orden, sino también la esfera descendente que incorpora lo inconsciente, lo nocturno y lo misterioso. Sin embargo, integrar este ámbito inferior en nuestra vida psíquica contrasta con nuestra visión occidental del mundo, en la que estos dos dominios se consideran opuestos y mutuamente excluyentes. El lenguaje mitopoético y los mitologemas que se manifiestan en los distintos mitos proporcionan los medios para ahondar en las profundas paradojas que se hallan en el núcleo de la cosmovisión total. Mitos como Añañuca (Chile), Osiris (Egipto), Dioniso (Grecia) o Innana (Sumeria) ponen de relieve el camino descendente, proporcionando una narrativa simbólica de una transformación o giro arquetípico, un momento clave de "giro sobre su propio eje" que fusiona los reinos de la Vida y la Muerte, el ascenso y el descenso, el nacimiento y la decadencia. Para vivir esta vía de transformación paradójica y generadora, el individuo debe buscar su mito personal no fuera de sí mismo, sino en su interior, de donde brota el Suprasentido.

[Circular RNA ame_circ_000115 regulates expression of genes in larval gusts of Apis mellifera ligustica stressed by Ascosphaera apis].

Circular RNAs (circRNAs) are a new class of non-coding RNAs, which have been confirmed to regulate insect gene expression and immune response through multiple manners such as competing endogenous RNA (ceRNA) regulatory network. Currently, function of circRNA in honey bee immune response remains unclear. In this study, PCR and Sanger sequencing were performed to validate the back splicing (BS) site of ame_circ_000115 (in short ac115). RT-qPCR was used to detect the expression profile of ac115 in larval guts of Apis mellifera ligustica stressed by Ascosphaera apis. Dual-luciferase reporter gene assay was conducted to verify the binding relationship between ac115 and ame-miR-13b. Interference of ac115 in larval guts was carried out by feeding specific siRNA, followed by determination of the effect of ac115 interference on expression of six genes relevant to host immune response. The results confirmed the existence of BS site within ac115. Compared with the un-inoculated group, the expression of ac115 in 4-day-old larval gut of the A. apis-inoculated group was up-regulated with extreme significance (P < 0.000 1), while that in 5- and 6-day-old larval guts were significantly up-regulated (P < 0.05). The brightness of specific band for ac115 in 4-, 5- and 6-day-old larval guts of the siRNA-circ_000115-fed group gradually became weak, whereas that of the siRNA-scrambl-fed group was pretty high without obvious variation. Compared with that of the siRNA-scramble-fed group, the expression of ac115 in 4-day-old larval gut of the siRNA-circ_000115-fed group was significantly down-regulated (P < 0.05), whereas that of the 5- and 6-day-old larval guts were down-regulated with extreme significance (P < 0.001). Ame-miR-13b was truly existed and expressed in A. m. ligustica larval guts, and there was true binding relationship between ac115 and ame-miR-13b. Compared with that of the siRNA-scramble-fed group, the expression of antimicrobial peptide genes hymenoptaecin and abaecin in 6-day-old larval gut of the siRNA-circ_000115-fed group was significantly up-regulated (P < 0.05), while that of ecdysone receptor (Ecr) was down-regulated with extreme significance (P < 0.01). These results indicate that ac115 is truly expressed in A. m. ligustica larval guts, BS site truly exists within ac115, and effective interference of ac115 in A. m. ligustica larval guts can be achieved via feeding siRNA. Moreover, ac115 potentially regulates Ecr expression through adsorption of ame-miR-13b and expression of hymenoptaecin and abaecin using a non-ceRNA manner, further participating in host stress-response.

Cytotoxicities of Co-occurring alternariol, alternariol monomethyl ether and tenuazonic acid on human gastric epithelial cells.

Alternariol (AOH), alternariol monomethyl ether (AME) and tenuazonic acid (TeA) are the three major Alternaria toxin contaminants in food. In the present study, we conducted their single and combined toxicity analyses using human gastric epithelial cell line (GES-1) that was first exposed to the toxins when they entered the human body. By comparing the cytotoxicity IC50, we found that compared to several other mycotoxins with limit standards there was cytotoxicity DON > OTA > AME > AOH > ZEN > TeA. Further, we obtained combination index (CI)-isobologram equation by the Chou-Talalay method according to a toxin ratio of 1:1:2 and carried out the combined toxicity analysis of the three binary and ternary compounds, and the results showed that AOH + AME + TeA showed synergistic toxic effects. Based on the co-occurring status, we also carried out the combined toxicity analysis of AME and AOH at different ratios and found antagonistic effects at low cytotoxic concentrations as well as synergistic and additive effects at high concentrations. Also, we found that all three and their combinations caused apoptosis, activation of caspase-3 cleavage, activation of DNA damage pathways ATR-Chk1-P53 and ATM-Chk2-P53. In conclusion, we used GES-1 cells to inform the risk of coaction of AOH, AME, and TeA in dietary exposure.

Degradation of Alternaria mycotoxins by UV-C irradiation: Effect of selected process and exposure to food components.

Alternariol (AOH) and alternariol monomethyl ether (AME) are two Alternaria mycotoxins with high occurrence rates in food systems. This study aimed to investigate the photodegradation of AOH and AME by ultraviolet-C (UV-C) irradiation. The effect of UV-C intensity, pH, treatment time, solvents and the exposure of food components were evaluated. After treated by UV-C irradiation at 3500 µW/cm2 for 90 min, AOH samples in methanol, aqueous solution and solid state were degraded by 89.1%, 72.9% and 53.2%, respectively, while the degradation percentages of AME were 86.6%, 50.1% and 11.1%, respectively. Increasing irradiation intensity and prolonging irradiation time could significantly facilitate the degradation of AOH and AME. An alkaline environment (pH = 11) was more conducive to the degradation of toxins. In addition, 2.5 mg mL-1 citric acid or malic acid increased the photodegradation of AOH and AME to 94.6% and 95.3%, 93.2% and 70.5%, respectively. However, protein, polyphenols and vitamin C exerted inhibitory effects on the degradation, while 10% glucose or sucrose reduced the photodegradation of AOH and AME to 65.9% and 40.3%. UV-C treatment could effectively reduce the content of AOH and AME, with the highest efficiency achieved in methanol and alkaline environment. By contrast, UV-C irradiation is more effective in degrading toxins in some liquid foods rich in organic acids but lacking in protein. The utilization of UV-C radiation appears to be a potentially useful approach for decreasing the underlying risk of Alternaria mycotoxin contamination in foods.

Circular RNA ame_circ_000115 regulates expression of genes in larval gusts of Apis mellifera ligustica stressed by Ascosphaera apis / 生物工程学报

Circular RNAs (circRNAs) are a new class of non-coding RNAs, which have been confirmed to regulate insect gene expression and immune response through multiple manners such as competing endogenous RNA (ceRNA) regulatory network. Currently, function of circRNA in honey bee immune response remains unclear. In this study, PCR and Sanger sequencing were performed to validate the back splicing (BS) site of ame_circ_000115 (in short ac115). RT-qPCR was used to detect the expression profile of ac115 in larval guts of Apis mellifera ligustica stressed by Ascosphaera apis. Dual-luciferase reporter gene assay was conducted to verify the binding relationship between ac115 and ame-miR-13b. Interference of ac115 in larval guts was carried out by feeding specific siRNA, followed by determination of the effect of ac115 interference on expression of six genes relevant to host immune response. The results confirmed the existence of BS site within ac115. Compared with the un-inoculated group, the expression of ac115 in 4-day-old larval gut of the A. apis-inoculated group was up-regulated with extreme significance (P < 0.000 1), while that in 5- and 6-day-old larval guts were significantly up-regulated (P < 0.05). The brightness of specific band for ac115 in 4-, 5- and 6-day-old larval guts of the siRNA-circ_000115-fed group gradually became weak, whereas that of the siRNA-scrambl-fed group was pretty high without obvious variation. Compared with that of the siRNA-scramble-fed group, the expression of ac115 in 4-day-old larval gut of the siRNA-circ_000115-fed group was significantly down-regulated (P < 0.05), whereas that of the 5- and 6-day-old larval guts were down-regulated with extreme significance (P < 0.001). Ame-miR-13b was truly existed and expressed in A. m. ligustica larval guts, and there was true binding relationship between ac115 and ame-miR-13b. Compared with that of the siRNA-scramble-fed group, the expression of antimicrobial peptide genes hymenoptaecin and abaecin in 6-day-old larval gut of the siRNA-circ_000115-fed group was significantly up-regulated (P < 0.05), while that of ecdysone receptor (Ecr) was down-regulated with extreme significance (P < 0.01). These results indicate that ac115 is truly expressed in A. m. ligustica larval guts, BS site truly exists within ac115, and effective interference of ac115 in A. m. ligustica larval guts can be achieved via feeding siRNA. Moreover, ac115 potentially regulates Ecr expression through adsorption of ame-miR-13b and expression of hymenoptaecin and abaecin using a non-ceRNA manner, further participating in host stress-response.

Biofilm stratification in counter-diffused membrane biofilm bioreactors (MBfRs) for aerobic methane oxidation coupled to aerobic/anoxic denitrification: Effect of oxygen pressure.

Aerobic methane oxidation coupled with denitrification (AME-D) executed in membrane biofilm bioreactors (MBfRs) provides a high promise for simultaneously mitigating methane (CH4) emissions and removing nitrate in wastewater. However, systematically experimental investigation on how oxygen partial pressure affects the development and characteristics of counter-diffusional biofilm, as well as its spatial stratification profiles, and the cooperative interaction of the biofilm microbes, is still absent. In this study, we combined Optical Coherence Tomography (OCT) with Confocal Laser Scanning Microscopy (CLSM) to in-situ characterize the development of counter-diffusion biofilm in the MBfR for the first time. It was revealed that oxygen partial pressure onto the MBfR was capable of manipulating biofilm thickness and spatial stratification, and then managing the distribution of functional microbes. With the optimized oxygen partial pressure of 5.5 psig (25% oxygen content), the manipulated counter-diffusional biofilm in the AME-D process obtained the highest denitrification efficiency, due mainly to that this biofilm had the proper dynamic balance between the aerobic-layer and anoxic-layer where suitable O2 gradient and sufficient aerobic methanotrophs were achieved in aerobic-layer to favor methane oxidation, and complete O2 depletion and accessible organic sources were kept to avoid constraining denitrification activity in anoxic-layer. By using metagenome analysis and Fluorescence in situ hybridization (FISH) staining, the spatial distribution of the functional microbes within counter-diffused biofilm was successfully evidenced, and Rhodocyclaceae, one typical aerobic denitrifier, was found to survive and gradually enriched in the aerobic layer and played a key role in denitrification aerobically. This in-situ biofilm visualization and characterization evidenced directly for the first time the cooperative path of denitrification for AME-D in the counter-diffused biofilm, which involved aerobic methanotrophs, heterotrophic aerobic denitrifiers, and heterotrophic anoxic denitrifiers.
