Urinary Incontinence Care in the Academic and Safety-Net Primary Care Settings: Opportunities to Improve Quality of Care.

OBJECTIVE: To compare the quality of urinary incontinence care for women in the safety-net and non-safety-net settings prior to referral to a specialist. METHODS: We performed a retrospective review of 200 women from two non-safety-net hospitals and 188 women from two safety-net hospitals who were referred to Urogynecology and Reconstructive Surgery specialists for bothersome UI between March 2017 and March 2020. We evaluated the care that women received 12-months prior to referral, by measuring adherence to a set of previously developed quality indicators (QIs), for example the performance of a urinalysis or pelvic exam. RESULTS: Women seen in safety-net hospitals were more likely to receive QI-compliant care than women in the non-safety-net hospitals prior to referral, with 55.53% of appropriate care given in the safety-net vs. 40.3% in the non-safety-net setting (p<0.01). Clinicians in the safety-net hospitals were more likely to adhere to QIs in patients with general, stress, and urgency incontinence. CONCLUSIONS: Women were more likely to receive timely, quality-based UI care in the safety net compared to the non-safety-net setting. This may be in part due to aspects unique to the safety-net system, including an eConsult referral system, which guides referring clinicians in appropriate management steps that should be taken prior to the specialist visit, as well as women's health focused primary care clinics.

Review of the anticancer properties of 6-shogaol: Mechanisms of action in cancer cells and future research opportunities.

Cancer is a major global health challenge that affects every nation and accounts for a large portion of the worldwide disease burden. Furthermore, cancer cases will rise significantly in the next few decades. The Food and Drug Administration has approved more than 600 drugs for treating diverse types of cancer. However, many conventional anticancer medications cause side effects, and drug resistance develops as the treatment proceeds with a concomitant impact on patients' quality of life. Thus, exploring natural products with antitumor properties and nontoxic action mechanisms is essential. Ginger (Zingiber officinale Roscoe) rhizome has a long history of use in traditional medicine, and it contains biologically active compounds, gingerols and shogaols. The main ginger shogaol is 6-shogaol, whose concentration dramatically increases during the processing of ginger, primarily due to the heat-induced conversion of 6-gingerol. Some studies have demonstrated that 6-shogaol possesses biological and pharmacological properties, such as antioxidant, anti-inflammatory, and anticancer activities. The mechanism of action of 6-shogaol as an anticancer drug includes induction of paraptosis, induction of apoptosis, increase in the production of reactive oxygen species, induction of autophagy, and the inhibition of AKT/mTOR signaling. Despite this knowledge, the mechanism of action of 6-shogaol is not fully understood, and the scientific data on its therapeutic dose, safety, and toxicity are not entirely described. This review article examines the potential of 6-shogaol as an anticancer drug, addressing the limitations of current medications; it covers 6-shogaol's attributes, mechanism of action in cancer cells, and opportunities for future research.

Comparison of distance covered, physiological cost, and perceived exertion in four six-minute walk test protocols.

Objective: There is evidence that indicates that the Walked Distance (WD) in the 6-Minute Walk Test (6MWT) would be sensitive to the type of track and encouragement. The aim of study was compared the impact of track type and verbal encouragement provided in the 6MWT on WD, physiological cost, perceived exertion, and gait efficiency in healthy young adults unfamiliar with the test. Method: WD, heart rate, subjective sensation of dyspnea (SSD), and fatigue (SSF) were measured in four 6MWT protocols: i) 30 m linear track and protocolized encouragement (LT + PE), ii) 30 m linear track and constant encouragement (LT + CE), iii) 81 m elliptical track and protocolized encouragement (ET + PE), and iv) 81 m elliptical track and constant encouragement (ET + CE). In addition, the Gait Efficiency Index (GIE) associated with physiological cost, dyspnea and fatigue was calculated and compared between the different protocols. Results: The WD was significantly higher in the ET + CE protocol. The percentage of the heart rate reserve used (%HRRu) at minute 6 was higher in the ET + CE protocol. The SSD and SSD had difference in startup time between the protocols. The GEI was higher in %HRRu, SSD, and SSF for the ET + CE protocol. Conclusion: The ET + CE protocol showed a significant increase in WD during the 6MWT in healthy young adults. Although it obtained the highest physiological cost, it did not present perceptual differences when entering cardiopulmonary assessment windows relevant to a more efficient test for the participant. It is advisable to discuss, based on the findings, the fundamental objective of the 6MWT and national and international recommendations to achieve a result as close as possible to the real maximal effort.

Beyond A and B Compartments: how major nuclear locales define nuclear genome organization and function.

Models of nuclear genome organization often propose a binary division into active versus inactive compartments, yet they overlook nuclear bodies. Here we integrated analysis of sequencing and image-based data to compare genome organization in four human cell types relative to three different nuclear locales: the nuclear lamina, nuclear speckles, and nucleoli. Whereas gene expression correlates mostly with nuclear speckle proximity, DNA replication timing correlates with proximity to multiple nuclear locales. Speckle attachment regions emerge as DNA replication initiation zones whose replication timing and gene composition vary with their attachment frequency. Most facultative LADs retain a partially repressed state as iLADs, despite their positioning in the nuclear interior. Knock out of two lamina proteins, Lamin A and LBR, causes a shift of H3K9me3-enriched LADs from lamina to nucleolus, and a reciprocal relocation of H3K27me3-enriched partially repressed iLADs from nucleolus to lamina. Thus, these partially repressed iLADs appear to compete with LADs for nuclear lamina attachment with consequences for replication timing. The nuclear organization in adherent cells is polarized with nuclear bodies and genomic regions segregating both radially and relative to the equatorial plane. Together, our results underscore the importance of considering genome organization relative to nuclear locales for a more complete understanding of the spatial and functional organization of the human genome.

Validation of Arabic versions of the child psychosocial distress screener and pediatric symptom checklist for young adolescents living in vulnerable communities in Lebanon.

BACKGROUND: In humanitarian settings, brief screening instruments for child psychological distress have potential to assist in assessing prevalence, monitoring outcomes, and identifying children and adolescents in most need of scarce resources, given few mental health professionals for diagnostic services. Yet, there are few validated screening tools available, particularly in Arabic. METHODS: We translated and adapted the Child Psychosocial Distress Screener (CPDS) and the Pediatric Symptom Checklist (PSC) and conducted a validation study with 85 adolescents (aged 10-15) in Lebanon. We assessed internal consistency; test-retest reliability; convergent validity between adolescent- and caregiver-report and between the two measures; ability to distinguish between clinical and non-clinical samples; and concurrent validity against psychiatrist interview using the Kiddie Schedule for Affective Disorders and Schizophrenia. RESULTS: The translated and adapted child-reported PSC-17 and PSC-35, and caregiver-reported PSC-35 all showed adequate internal consistency and test-retest reliability and high concurrent validity with psychiatrist interview and were able to distinguish between clinical and non-clinical samples. However, the caregiver-reported PSC-17 did not demonstrate adequate performance in this setting. Child-reported versions of the PSC outperformed caregiver-reported versions and the 35-item PSC scales showed stronger performance than 17-item scales. The CPDS showed adequate convergent validity with the PSC, ability to distinguish between clinical and non-clinical samples, and concurrent validity with psychiatrist interview. Internal consistency was low for the CPDS, likely due to the nature of the brief risk-screening tool. There were discrepancies between caregiver and child-reports, worthy of future investigation. For indication of any diagnosis requiring treatment, we recommend cut-offs of 5 for CPDS, 12 for child-reported PSC-17, 21 for child-reported PSC-35, and 26 for caregiver-reported PSC-35. CONCLUSIONS: The Arabic PSC and CPDS are reliable and valid instruments for use as primary screening tools in Lebanon. Further research is needed to understand discrepancies between adolescent and caregiver reports, and optimal methods of using multiple informants.

New insights into the anticancer therapeutic potential of icaritin and its synthetic derivatives.

Icaritin is a natural prenylated flavonoid derived from the Chinese herb Epimedium. The compound has shown antitumor effects in various cancers, especially hepatocellular carcinoma (HCC). Icaritin exerts its anticancer activity by modulating multiple signaling pathways, such as IL-6/JAK/STAT3, ER-α36, and NF-κB, affecting the tumor microenvironment and immune system. Several clinical trials have evaluated the safety and efficacy of icaritin in advanced HCC patients with poor prognoses, who are unsuitable for conventional therapies. The results have demonstrated that icaritin can improve survival, delay progression, and produce clinical benefits in these patients, with a favorable safety profile and minimal adverse events. Moreover, icaritin can enhance the antitumor immune response by regulating the function and phenotype of various immune cells, such as CD8+ T cells, MDSCs, neutrophils, and macrophages. These findings suggest that icaritin is a promising candidate for immunotherapy in HCC and other cancers. However, further studies are needed to elucidate the molecular mechanisms and optimal dosing regimens of icaritin and its potential synergistic effects with other agents. Therefore, this comprehensive review of the scientific literature aims to summarize advances in the knowledge of icaritin in preclinical and clinical studies as well as the pharmacokinetic, metabolism, toxicity, and mechanisms action to recognize the main challenge, gaps, and opportunities to develop a medication that cancer patients can use. Thus, our main objective was to clarify the current state of icaritin for use as an anticancer drug.

Evaluating a Movement-Based Mental Health Promotion Intervention for Refugee Children in Uganda: A Quasi-Experimental Study.

OBJECTIVE: Mental health promotion interventions are widely implemented in humanitarian settings and low- and middle-income contexts (LMICs), yet evidence on effectiveness is scarce and mixed. This study evaluated the movement-based mental health promotion intervention "TeamUp" in Bidibidi refugee settlement, in Northern Uganda. METHOD: A quasi-experimental study including four schools (two per arm) assessed the outcomes of 10- to 15-year-old South Sudanese and Ugandan children (n = 549). Randomly allocated, they either participated in up to 11 TeamUp sessions (n = 265) provided by trained facilitators; or belonged to a control group, which continued care as usual (n = 284). Primary outcomes measured psychosocial wellbeing, friendships and attitude to school; secondary outcomes included traumatic distress, depressive symptoms, quality of life, physical health, bullying, interoceptive awareness, and irritability. Data were collected at baseline and endline. RESULTS: Children joining TeamUp, showed significantly more improvements on primary outcomes: emotional and psychosocial wellbeing (Mdiff = -1.49, SE = 0.6, p = .01), satisfaction with and attitude toward school (-0.57, SE = 0.2, p = .004); and secondary outcomes: traumatic stress (2.64, SE = 0.8, p < .001), health-related quality of life (-1.56, SE = 0.4, p = .001), physical health (-0.78, SE = 0.3, p = .014) and the TeamUp mechanisms of action scale (-3.34, SE = 0.9, p < .001), specifically the subscales social connectedness (-0.74, SE = 0.3, p = .007) and sense of agency (-0.91, SE = 0.3, p = .005), compared to the control group. No significant differences were found on bullying, interoceptive awareness, irritability and depressive symptoms. CONCLUSION: The results are promising for TeamUp as a mental health promotion intervention for children affected by armed-conflict, displacement and on-going adversity. Further research will need to assess the intervention's effectiveness.

Follow-up and Mediation Outcomes of a Movement-Based Mental Health Promotion Intervention for Refugee Children in Uganda.

OBJECTIVE: There is limited evidence for the effectiveness of mental health promotion interventions in low- and middle-income settings, especially for longer-term benefits. This study evaluates the 5-month follow-up outcomes of a movement-based mental health promotion intervention (TeamUp) for refugee children in Northern Uganda (West Nile) and further investigates what explains longer-term benefits. METHODS: This quasi-experimental study was conducted in four primary schools, randomly allocated to an experimental or a control condition. Enrolled in the study were 549 children ages 10-15 years (n = 265 TeamUp; n = 284 control group). Primary outcomes were psychosocial well-being (Stirling Children's Wellbeing Scale), attitude toward school, and satisfaction with friendships (Multidimensional Students Life Satisfaction Scale [Friends and School subscales]). Mediators included social connectedness and sense of agency. RESULTS: At 5 months postintervention, 467 (85.1%) children were retained. Intent-to-treat analyses demonstrated sustained benefits for TeamUp for well-being (estimated mean difference -1.88, 95% CI -3.14 to -0.66, p = .003, effect size Cohen's d = 0.25) and friendships (-1.52, 95% CI -2.55 to -0.48, p = .005, d = 0.25). There were no significant between-group differences for attitude toward school. Secondary benefits were shown for traumatic stress (2.18, 95% CI 0.45 to 3.91, p = .014, d = 0.21), quality of life (-1.29, 95% CI -2.31 to -0.30, p = .014, d = 0.21), bullying (0.53, 95% CI 0.08 to 0.97, p = .020, d = 0.20), and depression symptoms (1.31, 95% CI 0.09 to 2.52, p = .035, d = 0.18). Increased sense of connectedness mediates the effect of TeamUp on improving well-being (indirect effect = 0.30, SE = 0.13, p = .001), explaining 15% of variance. CONCLUSION: This study shows sustained benefits of a mental health promotion intervention 5 months postintervention. Prolonged benefits are explained by an increase in social connectedness.

Human adenovirus-associated health risk in the recreational waters of the Yal-ku lagoon in the Mexican Caribbean.

The study objective was to evaluate human faecal contamination impacts in the Yal-ku lagoon in the Mexican Caribbean and to estimate adenovirus infection and illness risks associated with recreational exposure during water activities. A total of 20 water samples (10 from each site × two sites) (50 L) were collected monthly over a period of 12 months from two selected sampling sites in the swimming area of the Yal-ku lagoon. The occurrence of faecal-associated viruses was explored, and human adenovirus (HAdV) and pepper mild mottle virus (PMMoV) concentrations were quantified. A quantitative microbial risk assessment (QMRA) model was used to estimate exposure and subsequent adenovirus infection and illness risk for 1 h of swimming or snorkelling. Somatic and F + -specific coliphages occurred in 100% of the samples. Both HAdV and PMMoV were detected at a 60% frequency thereby indicating persistent faecal inputs. PMMoV concentrations (44-370 GC/L) were relatively lower than the concentrations of HAdV (64-1,000 GC/L). Estimated mean adenovirus risks were greater for snorkelling than for swimming by roughly one to two orders of magnitude and estimated mean illness risks for snorkelling were >32/1,000. Human faecal contamination is frequent in the Yal-ku lagoon, which is associated with human gastrointestinal illness.

Discovery of novel microRNA mimic repressors of ribosome biogenesis.

While microRNAs and other non-coding RNAs are the next frontier of novel regulators of mammalian ribosome biogenesis (RB), a systematic exploration of microRNA-mediated RB regulation has not yet been undertaken. We carried out a high-content screen in MCF10A cells for changes in nucleolar number using a library of 2603 mature human microRNA mimics. Following a secondary screen for nucleolar rRNA biogenesis inhibition, we identified 72 novel microRNA negative regulators of RB after stringent hit calling. Hits included 27 well-conserved microRNAs present in MirGeneDB, and were enriched for mRNA targets encoding proteins with nucleolar localization or functions in cell cycle regulation. Rigorous selection and validation of a subset of 15 microRNA hits unexpectedly revealed that most of them caused dysregulated pre-rRNA processing, elucidating a novel role for microRNAs in RB regulation. Almost all hits impaired global protein synthesis and upregulated CDKN1A (p21) levels, while causing diverse effects on RNA Polymerase 1 (RNAP1) transcription and TP53 protein levels. We provide evidence that the MIR-28 siblings, hsa-miR-28-5p and hsa-miR-708-5p, potently target the ribosomal protein mRNA RPS28 via tandem primate-specific 3' UTR binding sites, causing a severe pre-18S pre-rRNA processing defect. Our work illuminates novel microRNA attenuators of RB, forging a promising new path for microRNA mimic chemotherapeutics.

Internet of Things and citizen science as alternative water quality monitoring approaches and the importance of effective water quality communication.

The increasing demand for water and worsening climate change place significant pressure on this vital resource, making its preservation a global priority. Water quality monitoring programs are essential for effectively managing this resource. Current programs rely on traditional monitoring approaches, leading to limitations such as low spatiotemporal resolution and high operational costs. Despite the adoption of novel monitoring approaches that enable better data resolution, the public's comprehension of water quality matters remains low, primarily due to communication process deficiencies. This study explores the advantages and challenges of using Internet of Things (IoT) and citizen science as alternative monitoring approaches, emphasizing the need for enhancing public communication of water quality data. Through a systematic review of studies implemented on-field, we identify and propose strategies to address five key challenges that IoT and citizen science monitoring approaches must overcome to mature into robust sources of water quality information. Additionally, we highlight three fundamental problems affecting the water quality communication process and outline strategies to convey this topic effectively to the public.

The effect of clinically relevant beta-lactam, aminoglycoside, and quinolone antibiotics on bacterial extracellular vesicle release from E. coli.

Sepsis, a leading cause of death in hospitals, can be defined as a dysregulated host inflammatory response to infection, which can lead to tissue damage, organ failure, and cardiovascular complications. Although there is no cure for sepsis, the condition is typically managed with broad spectrum antibiotics to eliminate any potential bacterial source of infection. However, a potential side-effect of antibiotic treatment is the enhanced release of bacterial extracellular vesicles (BEVs). BEVs are membrane-bound nanoparticles produced by a variety of mechanisms, one of which includes the pinching-off of the outer membrane (in Gram-negative bacteria) to enclose proteins and other biological molecules for transport and intercellular communication. Some of the Gram-negative EV cargo, including Peptidoglycan associated lipoprotein (Pal) and Outer membrane protein A (OmpA), have been shown to induce both acute and chronic inflammation in host tissue. We hypothesize that antibiotic concentration and its mechanism of action can have an effect on the amount of released BEVs, which could potentially exacerbate the host inflammatory response. In this study, we evaluated nine clinically relevant antibiotics for their effect on EV release from Escherichia coli. EVs were characterized using immunoblotting, nanoparticle tracking analysis, and transmission electron microscopy. Several beta-lactam antibiotics caused significantly more EV release, while quinolone and aminoglycosides caused relatively less vesiculation. Further study is warranted to corroborate the correlation between an antibiotic's mechanism of action and its effect on EV release, but these results underline the importance of antibiotic choice when treating sepsis patients.

Inexpensive and Easy to Set Up Robotic Cardiac Simulator Offers "Unlimited" Endoscopic Coronary Artery Bypass Grafting Experience: Proof of Concept.

OBJECTIVE: Robotic totally endoscopic coronary artery bypass (TECAB) grafting is the least invasive form of coronary bypass surgery. However, despite its advantages, this approach has not gained widespread adoption. One possible reason is the advanced and complex robotic skills required to execute a totally endoscopic sutured coronary anastomosis. We prepared a novel, inexpensive, easy to set up robotic TECAB simulator. METHODS: A pig heart was placed in a cardboard box, and 3 holes were made on the side to mimic the exposure and surgical ergonomics of TECAB port placement. Four robotic ports were placed and docked to the da Vinci Si robot (Intuitive Surgical, Sunnyvale, CA, USA). Monofilament 7:0 suture (7 cm long) was used to perform the anastomosis to the left anterior descending artery using remnant conduit. Seven cardiac surgeons of various training levels participated and were asked to fill out a 10-point questionnaire. RESULTS: The cost of the simulator totaled $20 per session, with 20 min to assemble. Each session allowed each trainee to practice 3 to 4 coronary anastomoses. Three cardiac surgeons completed the survey and strongly agreed that the model was easy to set up, the anastomotic exercise was realistic, and that this practice helped them gain confidence. CONCLUSIONS: Our TECAB simulator is inexpensive, easy to set up, and allows trainees to practice endoscopic coronary suturing. We believe this to be a valuable training tool to learn how to do TECAB for established surgeons and that such a simulator may be of great value to cardiothoracic training programs and their trainees. Further studies are warranted.

3,3'-Diindolylmethane and indole-3-carbinol: potential therapeutic molecules for cancer chemoprevention and treatment via regulating cellular signaling pathways.

Dietary compounds in cancer prevention have gained significant consideration as a viable method. Indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) are heterocyclic and bioactive chemicals found in cruciferous vegetables like broccoli, cauliflower, cabbage, and brussels sprouts. They are synthesized after glycolysis from the glucosinolate structure. Clinical and preclinical trials have evaluated the pharmacokinetic/pharmacodynamic, effectiveness, antioxidant, cancer-preventing (cervical dysplasia, prostate cancer, breast cancer), and anti-tumor activities of I3C and DIM involved with polyphenolic derivatives created in the digestion showing promising results. However, the exact mechanism by which they exert anti-cancer and apoptosis-inducing properties has yet to be entirely understood. Via this study, we update the existing knowledge of the state of anti-cancer investigation concerning I3C and DIM chemicals. We have also summarized; (i) the recent advancements in the use of I3C/DIM as therapeutic molecules since they represent potentially appealing anti-cancer agents, (ii) the available literature on the I3C and DIM characterization, and the challenges related to pharmacologic properties such as low solubility, and poor bioavailability, (iii) the synthesis and semi-synthetic derivatives, (iv) the mechanism of anti-tumor action in vitro/in vivo, (v) the action in cellular signaling pathways related to the regulation of apoptosis and anoikis as well as the cell cycle progression and cell proliferation such as peroxisome proliferator-activated receptor and PPARγ agonists; SR13668, Akt inhibitor, cyclins regulation, ER-dependent-independent pathways, and their current medical applications, to recognize research opportunities to potentially use these compounds instead chemotherapeutic synthetic drugs.

Musculoskeletal Manifestations in Patients With Bardet-Biedl Syndrome: A Report of Two Cases.

We report two patients with musculoskeletal manifestations as part of the Bardet-Biedl syndrome. The first patient (case 1) was born with polydactyly and later diagnosed with coxa vara. He had homozygous pathogenic mutation in the BBS1 gene of the variant c.1645G>T (p.Glu459*). The second patient (case 2) had nyctalopia and progressive vision worsening had osteoarthritis symptoms. He had a heterozygous mutation in the BBS1 gene of the variant c.1169T>G (p.Met390Arg). Although polydactyly is the most prevalent musculoskeletal association in patients with the syndrome, co-management of the musculoskeletal manifestations remains of utmost importance in patients with the syndrome.

Morphological characteristics of astrocytes of the fastigial nucleus.

Astrocytes are a diverse and morphologically complex class of glial cells restricted to the central nervous system which have been implicated in the modulation of neuronal activity. The cerebellum is involved in planning movements and motor learning. Within the cerebellum three deep cerebellar nuclei (dentate, interposed and fastigial) provide the sole neuronal output. The fastigial nucleus participates in saccadic and vestibular function, and recent evidence disclosed neuronal projections to cognitive, affective, and motor areas. However, thus far there are no reliable descriptions of the distribution and morphological classifications of astrocytes in this nucleus. This work aims to describe the characteristics of astrocytes of the fastigial nucleus based on the expression of GFP in a transgenic mouse model.

hESC-derived striatal progenitors grafted into a Huntington's disease rat model support long-term functional motor recovery by differentiating, self-organizing and connecting into the lesioned striatum.

BACKGROUND: Huntington's disease (HD) is a motor and cognitive neurodegenerative disorder due to prominent loss of striatal medium spiny neurons (MSNs). Cell replacement using human embryonic stem cells (hESCs) derivatives may offer new therapeutic opportunities to replace degenerated neurons and repair damaged circuits. METHODS: With the aim to develop effective cell replacement for HD, we assessed the long-term therapeutic value of hESC-derived striatal progenitors by grafting the cells into the striatum of a preclinical model of HD [i.e., adult immunodeficient rats in which the striatum was lesioned by monolateral injection of quinolinic acid (QA)]. We examined the survival, maturation, self-organization and integration of the graft as well as its impact on lesion-dependent motor alterations up to 6 months post-graft. Moreover, we tested whether exposing a cohort of QA-lesioned animals to environmental enrichment (EE) could improve graft integration and function. RESULTS: Human striatal progenitors survived up to 6 months after transplantation and showed morphological and neurochemical features typical of human MSNs. Donor-derived interneurons were also detected. Grafts wired in both local and long-range striatal circuits, formed domains suggestive of distinct ganglionic eminence territories and displayed emerging striosome features. Moreover, over time grafts improved complex motor performances affected by QA. EE selectively increased cell differentiation into MSN phenotype and promoted host-to-graft connectivity. However, when combined to the graft, the EE paradigm used in this study was insufficient to produce an additive effect on task execution. CONCLUSIONS: The data support the long-term therapeutic potential of ESC-derived human striatal progenitor grafts for the replacement of degenerated striatal neurons in HD and suggest that EE can effectively accelerate the maturation and promote the integration of human striatal cells.

Transsulfuration pathway: a targeting neuromodulator in Parkinson's disease.

The transsulfuration pathway (TSP) is a metabolic pathway involving sulfur transfer from homocysteine to cysteine. Transsulfuration pathway leads to many sulfur metabolites, principally glutathione, H2S, taurine, and cysteine. Key enzymes of the TSP, such as cystathionine ß-synthase and cystathionine γ-lyase, are essential regulators at multiple levels in this pathway. TSP metabolites are implicated in many physiological processes in the central nervous system and other tissues. TSP is important in controlling sulfur balance and optimal cellular functions such as glutathione synthesis. Alterations in the TSP and related pathways (transmethylation and remethylation) are altered in several neurodegenerative diseases, including Parkinson's disease, suggesting their participation in the pathophysiology and progression of these diseases. In Parkinson's disease many cellular processes are comprised mainly those that regulate redox homeostasis, inflammation, reticulum endoplasmic stress, mitochondrial function, oxidative stress, and sulfur content metabolites of TSP are involved in these damage processes. Current research on the transsulfuration pathway in Parkinson's disease has primarily focused on the synthesis and function of certain metabolites, particularly glutathione. However, our understanding of the regulation of other metabolites of the transsulfuration pathway, as well as their relationships with other metabolites, and their synthesis regulation in Parkinson´s disease remain limited. Thus, this paper highlights the importance of studying the molecular dynamics in different metabolites and enzymes that affect the transsulfuration in Parkinson's disease.

Functional effect of indole-3 carbinol in the viability and invasive properties of cultured cancer cells.

Cancer treatment typically involves multiple strategies, such as surgery, radiotherapy, and chemotherapy, to remove tumors. However, chemotherapy often causes side effects, and there is a constant search for new drugs to alleviate them. Natural compounds are a promising alternative to this problem. Indole-3-carbinol (I3C) is a natural antioxidant agent that has been studied as a potential cancer treatment. I3C is an agonist of the aryl hydrocarbon receptor (AhR), a transcription factor that plays a role in the expression of genes related to development, immunity, circadian rhythm, and cancer. In this study, we investigated the effect of I3C on cell viability, migration, invasion properties, as well as mitochondrial integrity in hepatoma, breast, and cervical cancer cell lines. We found that all tested cell lines showed impaired carcinogenic properties and alterations in mitochondrial membrane potential after treatment with I3C. These results support the potential use of I3C as a supplementary treatment for various types of cancer.

Current Status of the Therapeutic Approach for Dysmenorrhea.

Dysmenorrhea is the combination of cramps and pain associated with the menstrual period, and the symptoms affect at least 30% of women worldwide. Tolerance to symptoms depends on each person's pain threshold; however, dysmenorrhea seriously affects daily activities and chronically reduces the quality of life. Some dysmenorrhea cases even require hospitalization due to unbearable symptoms of severe pain. Dysmenorrhea is an underestimated affectation and remains even in different first-world countries as a taboo subject, promoted by the establishment of an apparent policy of gender equality. A person with primary or secondary dysmenorrhea requires medical assistance in choosing the best treatment and an integral approach. This review intends to demonstrate the impact of dysmenorrhea on quality of life. We describe the pathophysiology of this disorder from a molecular point of view and perform a comprehensive compilation and analysis of the most critical findings in the therapeutic management of dysmenorrhea. Likewise, we propose an interdisciplinary approach to the phenomenon of dysmenorrhea at the cellular level in a concise way and the botanical, pharmacological, and medical applications for its management. Since dysmenorrhea symptoms can vary between individuals, medical treatment cannot be generalized and depends on each patient. Therefore, we hypothesized that a suitable strategy could result from the combination of pharmacological therapy aided by a non-pharmacological approach.
