RESUMEN

Aim: This study seeks to explore the possibility of using vitamin E to alleviate the symptoms of polycystic ovarian syndrome (PCOS). Methods: Various computational methods were employed, including network pharmacology utilizing a compound-target-pathway approach, Swiss ADME, OSIRIS® property explorer, pkCSM, PASS online web resource and MOLINSPIRATION® software. In addition, in silico analysis of vitamin E was performed with ten receptors. Results & discussion: Our findings highlight the diverse potential of vitamin E in alleviating PCOS. The observed influence on hormones is in line with existing PCOS theories regarding cyst development, further enhancing the therapeutic promise of vitamin E. Conclusion: In conclusion, our computational analysis indicates that vitamin E shows potential as a therapeutic agent for alleviating PCOS in adolescents.


Polycystic ovarian syndrome (PCOS) is a common condition that affects many girls and young women during their reproductive years. PCOS can lead to problems with the menstrual cycle, difficulties with blood sugar control and sometimes infertility. Unfortunately, there's no specific treatment for PCOS yet. This study looked at whether vitamin E might be helpful in treating PCOS in young women. To find out, the researchers used advanced computer-based techniques and analyzed how vitamin E interacts with various parts of the body, including proteins and hormones. Vitamin E appears to influence hormones that play a role in PCOS and cyst formation. It may also have anti-inflammatory properties that could help reduce the symptoms of PCOS. In short, this study suggests that vitamin E might be a valuable option for treating PCOS in adolescents. However, further research and clinical trials are needed to confirm these findings before it can become a standard treatment. This research opens up new possibilities for finding effective solutions for PCOS, which can greatly improve the quality of life for many young women.

RESUMEN

The most prevalent endocrine and metabolic condition in women of reproductive age are polycystic ovary syndrome (PCOS) with significant risk factors such as circadian rhythm and melatonin disruption. The aim of this study is to assess the effect of vitamin E in combination with a combined oral contraceptive (COC) on continuous light-induced PCOS using hormonal measures, oxidative stress (OS) indicators, and the inhibin beta-A (INHBA) gene, which targets the melatonin protein kinase C (PKC) pathway. An in silico technique anticipated INHBA's binding affinity for vitamin E and COC. For the in vivo investigation (IAEC/240/2021), female SD rats were divided into six groups and subjected to a 16-week induction period, followed by a 2-month test drug treatment with drospirenone (DRSP) as a standard. Serum testosterone, FSH, melatonin, and OS were calculated as hormonal markers. The expression of the INHBA gene was studied to see if it could be linked to the circadian rhythm and OS via the melatonin PKC pathway. According to the in silico study, vitamin E and DRSP had higher binding energy for the INHBA (-8.6 kcal/mol and -8.4 kcal/mol, respectively). When compared to the control group, in vivo results showed a substantial decrease in testosterone levels (p = .05), as well as changes in FSH (p = .78) and melatonin (p = .13). IHNBA gene expression has also dramatically increased, stimulating FSH production in the pituitary gland. Vitamin E and COC concomitantly are beneficial against PCOS because it modulates OS, which in turn influences circadian rhythm and the melatonin PKC pathway.

RESUMEN

Polycystic ovarian syndrome (PCOS) is a hormone disorder common among reproductive-aged women. This is associated with the symptoms like an irregular menstrual cycle, excess androgens, and polycystic ovary. Interestingly, vitamin E acts like the hormone progesterone and improves insulin sensitivity in PCOS. The study aims to evaluate the therapeutic effect of vitamin E in combination with combined oral contraceptive (COC) against PCOS by in silico and in vivo methods. The therapeutic effect of vitamin E (25 and 50mg/kg) in combination with COC (0.4mg/kg) was screened by the in silico method using Auto dock vina 4.2.6. Additionally, in vivo studies with a letrozole-induced PCOS model were performed in 30 female SD rats (n = 6 in each group) for 8 weeks with different doses of vitamin E. Furthermore, histopathological features and the insulin receptor (INSR) gene were scrutinized. An in silico study showed that drospirenone and vitamin E have an excellent affinity to bind to INSR and have higher binding energy (- 8.5 kcal/mol and - 8.7 kcal/mol, respectively). In vivo results showed a significant reduction in elevated testosterone levels compared to that of the PCOS group; follicle-stimulating hormone (FSH) and insulin levels also showed significant changes and reversed anti-oxidant levels in a dose-dependent manner. Ovarian histopathological changes were observed in different follicle counts in addition to the INSR gene, which showed changes in densitometry values. Supplementation of vitamin E combined with COC could be effective against PCOS, and clinical studies must be carried out further.

RESUMEN

BACKGROUND: The aim of this systematic review is to ponder the possible mechanism of action of anthocyanin in Alzheimer's disease (AD), to prompt the development of anthocyanin-based dietary supplementation or therapeutic intervention for AD and to explore the natural sources of anthocyanins. METHODS: Electronic bibliographic databases such as PubMed, ScienceDirect, Proquest, DOAJ, Scopus, and Google Scholar were searched for preclinical studies probing the efficacy of anthocyanin on AD. The search strategy included no time limit, but was restricted to English. The review protocol is registered on PROSPERO, registration no. CRD42021272972. The systematic review followed the PICO approach for inclusion of reports. All the reports were appraised for risk of bias using the SYRCLE's RoB tool. RESULTS: Bibliographic details of the article, animal strain/weight/age, induction model, anthocyanin source, type of anthocyanin, dose, route of administration, duration, and the outcome measures were extracted from 12 retrieved reports explicitly. The implication of food-based anthocyanin in acute and long-term cognition and Aß mediated neurodegeneration appears alluring. Majority of the studies comprehended in this review had moderate methodological quality. DISCUSSION: Efficacy of anthocyanin in alleviating oxidative stress, reactive astrogliosis, cholinergic dysfunction, apoptosis, synaptotoxicity, neuroinflammation, tau hyperphosphorylation, dysregulated membrane potential, neuronal extracellular calcium, dysfunctional amyloidogenic pathway, and cognitive deficits in various rodent models of AD is manifested compositely in 12 studies.

RESUMEN

This is the first prospective study to investigate the association between kidney stones, bone mineral density, serum testosterone, colon cancer and O. formigenes colonization. 40 kidney stone patients and 85 controls were enrolled. O. formigenes colonization was established. BMD was examined from T- and Z-scores using dual energy absorptiometry. O. formigenes was found in 28 of 40 cases and 80 of 85 controls. BMD was significantly reduced in patients (p < 0.05). The evaluation revealed a significant association between lowered O. formigenes colonization and low testosterone. Urinary calcium and oxalates levels were greater in patient. Serum testosterone and urinary citrate concentrations was reduced in patients with a significant difference. Also an association between O. formigenes and colon cancer was noted. Absence of O. formigenes might stand for a pathogenic factor in calcium oxalate stone, low bone mineral density, low testosterone levels and also colon cancer, when antibiotics are prescribed generously.
