Diacylated anthocyanins from purple sweet potato (Ipomoeabatatas L.) attenuate hyperglycemia and hyperuricemia in mice induced by a high-fructose/high-fat diet / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Studies have shown that targeting xanthine oxidase (XO) can be a feasible treatment for fructose-induced hyperuricemia and hyperglycemia. This study aimed to evaluate the dual regulatory effects and molecular mechanisms of diacylated anthocyanins from purple sweet potato (diacylated AF-PSPs) on hyperglycemia and hyperuricemia induced by a high-fructose/high-fat diet. The body weight, organ index, serum biochemical indexes, and liver antioxidant indexes of mice were measured, and the kidneys were observed in pathological sections. The relative expression levels of messenger RNAs (mRNAs) of fructose metabolism pathway enzymes in kidney were detected by fluorescent real-time quantitative polymerase chain (qPCR) reaction technique, and the expression of renal transporter protein and inflammatory factor pathway protein was determined by immunohistochemistry (IHC) technique. Results showed that diacylated AF-PSPs alleviated hyperuricemia in mice, and that this effect might be related to the regulation of liver XO activity, lipid accumulation, and relevant renal transporters. Diacylated AF-PSPs reduced body weight and relieved lipid metabolism disorder, liver lipid accumulation, and liver oxidative stress, thereby enhancing insulin utilization and sensitivity, lowering blood sugar, and reducing hyperglycemia in mice. Also, diacylated AF-PSPs restored mRNA levels related to renal fructose metabolism, and reduced kidney injury and inflammation. This study provided experimental evidence for the mechanisms of dual regulation of blood glucose and uric acid (UA) by diacylated AF-PSPs and their utilization as functional foods in the management of metabolic syndrome.

Infección urinaria de presentación atípica: caso clínico y revisión de literatura

Introducción: el síndrome de orina púrpura es una presentación clínica poco frecuente en el ámbito de urgencias, caracterizado por coloración anormal de la orina secundaria a una reacción química de algunos patógenos que producen infección de vías urinarias, siendo más frecuente en pacientes con múltiples comorbilidades y diferentes factores de riesgo. Objetivo: el objetivo de este manuscrito es presentar el caso de un paciente con síntomas atípicos de infección de vías urinarias. Presentación del caso: varón de 88 años de edad, con antecedente de diabetes mellitus no insulino-requiriente, con hiperplasia prostática benigna que ingresó al servicio de urgencias por síntomas irritativos urinarios asociados a uso de sonda vesical, con orina de coloración violeta en bolsa recolectora. El urocultivo reportó la presencia de Proteus vulgaris multisensible, por lo que se decidió dar manejo con cefepima de 1 gr cada ocho horas, con lo cual se obtuvo una adecuada evolución clínica. Discusión y conclusión: el síndrome de la bolsa de orina púrpura es una presentación clínica atípica, pero muy llamativa de la infección urinaria. Esta se genera como resultado de la conversión del triptófano en la dieta en indoxil sulfato que, una vez se elimina por la orina, se transforma en índigo (color violeta) e indirrubina (color rojo), dando este aspecto clínico.

Background: Purple urine syndrome is a rare clinical presentation in the emergency room, characterized by abnormal colouration of the urine secondary to a chemical reaction of some pathogens that cause urinary tract infection, being more frequent in patients with multiple comorbidities and different risk factor's. Purpose: The objective of the article is present the case of a patient with atypical symptoms of urinary tract infection. Clinical case: An 88-year-old male, with a history of non-insulin diabetes mellitus, benign prostatic hyperplasia, who was admitted to the emergency room due to irritative urinary symptoms associated with the use of a urinary catheter, with purple urine in a collection bag. Urine culture reported the presence of multisensitive Proteus vulgaris, for which it was decided to give treatment with Cefepime 1 g every 8 hours, with which it was obtained with adequate clinical evolution. Conclusions: Purple urine bag syndrome is an atypical but very striking clinical presentation of urinary tract infection. This is generated as a result of the conversion of tryptophan in the diet into indoxyl sulfate, which, once it is eliminated in the urine, transforms into indigo (purple color) and indirubin (red color), giving this clinical appearance.

Precise and Sensitive Ambient Temperature Based Analytical Colorimetric Method for Pregabalin

Abstract Pregabalin, a GABA analogue is used to treat epilepsy and neuropathic pain. The drug poses problems in analytical quantification when estimated at a shorter UV wavelength. The expensive and non-repetitive reported analytical methods necessitate the utility and development of an accurate, precise, repetitive, simple and highly sensitive colorimetric method for pregabalin in solution as well as sustained release mini matrices. Pregabalin (having primary amino group) was derivatized at alkaline pH of mixture with optimized ninhydrin solution at ambient temperature (25oC). The ninhydrin-pregabalin derivatized complex (Ruhemann's Purple) was analyzed for drug concentration at absorption maximum (λmax) of 570nm. The linearity was observed in the concentration range of 5-150 µg/mL with coefficient of correlation, 0.998. The developed analytical method was validated according to ICH guidelines and proved to be highly sensitive (LOD 0.917µg/mL, LOQ 3.055µg/mL), with good inter-day as well as intra-day accuracy and precision as 4.65% and 3.75%, respectively. The proposed method was proved to be a simple, sensitive, precise and accurate for the estimation of the minute concentrations of pregabalin in pure form and the developed formulations. Results verified that the proposed method could determine pregabalin at the ambient temperature without requiring high temperatures used in the existing methods. It was concluded that developed method was easier and more suitable for analysis of pregabalin in quality control of commercial preparations

Light quality and dormancy overcoming in seed germination of Echium plantagineum L. (Boraginaceae) / Qualidade da luz e superação de dormência na germinação de sementes de Echium plantagineum L. (Boraginaceae)

Abstract Light is considered a factor that influences the seed germination of many weed species, and it can signal whether the environmental conditions are favorable or are not favorable for germination. We aimed to study if there is an influence of light quality and dormancy overcoming in seed germination of Echium plantagineum L. We carried out a 2 x 6 factorial experiment, with and without dormancy overcoming with potassium nitrate followed by immersion in gibberellic acid; six light qualities, obtained through the light filters: blue, green, red, far-red, white light and absence of light. The evaluations performed were germination speed index (GSI), average germination time (AGT), germination at the four and 14 days after seeding (DAS), accumulated germination and relative frequency of germination. We observed significant interaction among the light qualities and seed dormancy overcoming or not for the studied variables. There was no significant effect of light qualities, in the evaluated variables, when performing dormancy overcoming, presenting germination above 90% in all the light qualities. However, without dormancy overcoming, we observed greater GSI, germination at four and 14 DAS for the red light filter with 5, 4, 29 and 45%, respectively. When the seeds were submitted to the absence of light, and without dormancy overcoming, there was only 7% of germination at 14 DAS. The seeds of E. plantagineum presented greater germination under incidence of red light, without dormancy overcoming, being classified as preferably positively photoblastics, provided that the dormancy is not overcome.

Resumo A luz é considerada um fator que influencia a germinação das sementes de muitas espécies de plantas daninhas, podendo sinalizar se as condições ambientais são favoráveis ou não para a germinação. Objetivou-se estudar se há influência da qualidade da luz e superação de dormência na germinação de sementes de Echium plantagineum L. Realizou-se um experimento fatorial 2 x 6, com e sem superação de dormência com nitrato de potássio seguido pela imersão em ácido giberélico; seis qualidades de luz, obtidas através de filtros de luz: azul, verde, vermelho, vermelho-distante, luz branca e ausência de luz. As avaliações realizadas foram índice de velocidade de germinação (IVG), tempo médio de germinação (TMG), germinação aos quatro e 14 dias após a semeadura (DAS), germinação acumulada e frequência relativa de germinação. Observou-se interação significativa entre as qualidades de luz e a superação ou não de dormência das sementes para as variáveis estudadas. Não houve efeito significativo das qualidades de luz, nas variáveis avaliadas, ao realizar superação de dormência, apresentando germinação acima de 90% em todas as qualidades de luz. Todavia, sem superação de dormência, observou-se maior IVG, germinação aos quatro e 14 DAS para o filtro de luz vermelha com 5,4, 29 e 45%, respectivamente. Quando as sementes foram submetidas à ausência de luz, e sem superação de dormência, houve apenas 7% de germinação aos 14 DAS. As sementes de E. plantagineum apresentam maior germinação sob incidência de luz vermelha, sem superação de dormência, sendo classificadas como fotoblásticas positivas preferenciais, desde que não seja superada a dormência.

Viability of Cyperus rotundus L. tubers after application of herbicide in pre- and postemergence / Viabilidade de tubérculos de Cyperus rotundus L. após a aplicação de herbicidas em pré e pós-emergência

Chemical management is the most widely adopted technique to control weeds in sugarcane crops. Purple nutsedge (Cyperus rotundus L.) is among the most difficult species to control. Herbicides need to be absorbed and translocated in a sufficient amount for the tuber chain to be effective. Thus, this study aimed to evaluate the effectiveness of the herbicides sulfentrazone, diclosulam, imazapic, imazapyr, halosulfuron, ethoxysulfuron, monosodium methyl arsenate (MSMA), and 2,4-dichlorophenoxyacetic acid (2,4-D) in controlling C. rotundus and reducing the viability of its tubers. The experiment was carried out in a greenhouse in a completely randomized design, with nine treatments and four replications. The herbicides sulfentrazone (800 g active ingredient ­ ai·ha?1), diclosulam (193.17 g ai·ha?1), imazapic (133 g ai·ha?1), and imazapyr (500 g acid equivalent ­ ae·ha?1) were applied in preemergence at five days after planting the tubers, while halosulfuron (112.5 g ai·ha?1), ethoxysulfuron (135 g ai·ha?1), MSMA (1,975 g ai·ha?1), and 2,4-D (1,340 g ae·ha?1) were applied in postemergence (4 to 5 leaves). The parameters visual control, shoot dry matter, number of tubers and bulbs, weight of tubers + bulbs, number of epigeal manifestations, and tuber viability were analyzed. The herbicides diclosulam, halosulfuron, and ethoxysulfuron provided 100% control of the shoot at 90 days after application (DAA). All herbicides reduced the number of bulbs, weight of tubers + bulbs, and shoot dry matter. The herbicides sulfentrazone, imazapic, halosulfuron, ethoxysulfuron, and MSMA provided the highest reduction in tuber viability.(AU)

O manejo químico é o mais adotado para o controle de plantas daninhas na cultura da cana-de-açúcar. Entre as espécies de difícil controle está a tiririca (Cyperus rotundus L.). Os herbicidas utilizados precisam ser absorvidos e transportados para a cadeia de tubérculos em quantidades suficientes para serem eficazes. Assim, objetivou-se com este estudo avaliar a eficácia dos herbicidas sulfentrazona, diclosulam, imazapique, imazapir, halossulfurom, etoxissulfurom, metano arseniato ácido monossodico (MSMA) e ácido diclorofenoxiacético (2,4-D) no controle de C. rotundus e na redução da viabilidade de seus tubérculos. O experimento foi realizado em casa de vegetação, em delineamento inteiramente randomizado, com nove tratamentos e quatro repetições. Os herbicidas sulfentrazone (800 g ingrediente ativo ­ i.a.·ha-1), diclosulam (193,17 g i.a.·ha-1), imazapique (133 g i.a.·ha-1) e imazapir (500 g equivalente ­ e.a.·ha-1) foram aplicados cinco dias após o plantio dos tubérculos em pré-emergência, enquanto que o halossulfurom (112,5 g i.a.·ha-1), etoxissulfurom (135 g i.a.·ha-1), MSMA (1.975 g i.a.·ha-1) e 2,4-D (1.340 g e.a.·ha-1) foram aplicados em pós-emergência (4 a 5 folhas). Foram feitas avaliações visuais de controle, massa seca da parte aérea, número de tubérculos e bulbos, peso de tubérculos + bulbos, número de manifestações epígeas e viabilidade de tubérculos. Aos 90 dias após a aplicação (DAA) os herbicidas diclosulam, halossulfurom e etoxissulfurom propiciaram 100% de controle da parte aérea. Todos os herbicidas reduziram o número de bulbos, peso de tubérculos + bulbos e massa seca da parte aérea. Sulfentrazona, imazapic, halossulfurom, etoxissulfurom e MSMA foram os herbicidas que mais reduziram a viabilidade dos tubérculos.(AU)

Hematoma paroxístico de los dedos (Síndrome de Achenbach) / Paroxysmal finger haematoma (Achenbach syndrome)

RESUMEN El hematoma paroxístico de los dedos hace referencia a pacientes que padecen episodios súbitos de dolor y edema en uno o más dígitos con la subsecuente aparición de un hematoma, predominantemente en la región palmar de las falanges proximales. El hematoma paroxístico de los dígitos es una condición rara y benigna de etiología desconocida. Los síntomas prodrómicos como dolor, hormigueo y picazón pueden ocurrir desde minutos hasta horas antes de que aparezca el cambio de coloración. El sangrado subdérmico por lo general se detiene espontáneamente o minutos después de aplicar presión local y los cambios de coloración usualmente desaparecen. El diagnóstico se basa estrictamente en las características clínicas ya que todas las investigaciones de rutina suelen ser normales. El curso de esta condición es benigno y los síntomas se resuelven sin dejar secuelas permanentes. Los médicos deberían encontrarse alertas sobre esta condición para reconocerla y asesorar correctamente al paciente acerca de su pronóstico y evitar el pedido de estudios complementarios innecesarios.

SUMMARY Paroxysmal finger hematoma refers to patients suffering from episodic pain and swelling in one or more digits with subsequent appearance of a hematoma in the palmar aspect of the proximal phalanges. Paroxysmal finger hematoma is a rare and benign condition of unknown etiology. Prodromal symptoms such as pain, tingling and itching may occur from minutes to hours before the color change appears. Subdermal bleeding usually stops spontaneously or after local pressure is applied, and changes in coloration usually disappear. The diagnosis is strictly based on the clinical features since all routine investigations are usually normal. The course of this condition is benign and the symptoms resolve without permanent sequelae. Doctors should become aware of this condition to advise their patients about the prognosis and to avoid the request of unnecessary additional studies.

Methodology: This study used mouse as experimental animals with 24 female mouse, then mated with male mouse with a ratio (1 female: 1 male). After the vaginal plug was found in female mouse, then the essential oil of purple nutsedge tubers was induced orally (force-fed) according to the treatment dose. Each 6 female mice were grouped as a control group, and 3 treatment groups, consisting of controls (C) = 0.4 ml aquabides, treatment 1 (T1) = 4.5 mg/40g body weight, treatment 2 (T2) = 45 mg/40g body weight, and treatment 3 (T3) = 135 mg/40g body weight. After the one way Anova test, Ho is rejected, meaning there are significant differences and the analysis is continued with multiple comparison tests, in this case the Least Significant Difference (LSD) test is used. Results: The results shown that the induction of essential oils of purple nutsedge tubers can reduce the level of β3 integrin protein in uterus mouse significantly. Conclusion: It is suggested essential oil of purple nutsedge tubers has potential decrease and can reduce the level of β3 integrin protein in uterus mouse during the period of embryo implantation.

Purple Urinary Bag Syndrome

Purple Urinary Bag Syndrome occurs due to the precipitation and reaction of indigo and indirubin pigments with the synthetic materials in the catheter and urinary bag which gives the characteristic purple color. We report a case of a 59 years old woman with this rare entity.

A New Record and Characterization of Asparagus Purple Spot Caused by Stemphylium vesicarium in Korea

In 2017, small, elliptical, brownish purple spots on spears and ferns of asparagus were found in fields of Gangwon-do. The isolated fungal species was identified as an ascomycete Stemphylium vesicarium based on morphological characteristics and molecular phylogenic analyses including nucleotide sequences of the internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and cytochrome b (cytb). A pathogenicity test revealed that S. vesicarium was the causal agent of purple spot disease on asparagus. The occurrence of purple spots caused by S. vesicarium on asparagus is the first report in Korea.

Antifungal activity of selected plant extracts against Curvularia sp. infecting local purple sweet potato (Ipomoea batatas)

Aims@#The present study was designed to evaluate in vitro antifungal activity of plant extracts against Curvularia sp., a causative agent of leaf blotch in local purple sweet potato crops. @*Methodology and results@#The plants were selected on the basis of commonly used traditional remedies. Various dilutions, 1/2, 1/4, 1/6, 1/8 and 1/10 of black pepper, garden croton, garlic, tobacco and turmeric extracts were used for screening. The lesion characteristics on purple sweet potato leaves were collected from plots in MARDI Bachok. The “poisoning agar technique method” was used to get the antifungal activity. The results of antifungal activities were reported in terms of inhibition of mycelial growth of the test fungus. Out of five types of plant extracts used, only garlic and tobacco showed significantly high antifungal activity against the test pathogen based on poisoned food technique. Garlic extract showed complete inhibition (100%) at 1/2 dilution and more than 94% growth inhibition at concentrations as low as 1/10 dilution after seven days of incubation. However, black pepper and turmeric extracts showed moderate inhibition (20-70%) whereas, no inhibition was recorded in 1/8 and 1/10 dilution of garden croton extract. @*Conclusion, significance and impact of study@#Our findings suggested that garlic extract is the most potential antifungal agent against Curvularia sp. and can be used as bio-fungicide thus would reduce the dependency on synthetic fungicides by farmers.
