Menopause symptoms may be distressing, especially when they appear at a time when women are expected to play significant responsibilities in society. Numerous biological systems are influenced by the hormonal changes that start during the menopausal transition. This review attempts to decipher the complex relationship between obesity, menopause, and depression, citing some recent longitudinal and cross-sectional studies. Additionally, this study provides a summary of the different phytoestrogens, their sources, and probable mechanisms of action in addition to available therapeutic alternatives.

For this review purpose, the authors have gone through a vast number of articles from various scientific databases like PubMed, Google Scholar, and Web of Science.

It is becoming clear that the physiological basis for these menopausal symptoms is complicated and connected to estrogen deficiency, but not alone. Other hormones like FSH, LH, progesterone, and inhibin B are the major ones that are both directly and indirectly responsible for most of the menopausal symptoms. Numerous longitudinal and cross-sectional studies have found a direct relationship between the incidence of menopause and depression as well as obesity. Phytoestrogens like stilbene, lignans, isoflavone, and coumestan have been reported to be the alternatives to synthetic estrogen with lesser side effects, as reported in various studies.

The complex relationship between depression, menopause, and obesity presents a complex obstacle to women's health and overall well-being. There might be a lot of promising prospects for revolutionary advancements in women's health during the menopausal stage in the future. Promising drug development that targets not just one but also the three conditions -obesity, menopause, and depression - as well as more thorough research are needed to improve the healthcare system for women who suffer from these conditions.

Atherosclerosis is a complex cardiovascular disease often associated with mitochondrial dysfunction, which can lead to various cellular and metabolic abnormalities. Within the mitochondrial genome, specific mutations have been implicated in contributing to mitochondrial dysfunction. Atherosclerosis-associated m.15059G>A mutation has been of particular interest due to its potential role in altering mitochondrial function and cellular health.

This study aims to investigate the role of the atherosclerosis-associated m.15059G>A mutation in the development of mitochondrial dysfunction in monocyte-like cells.

Monocyte-like cytoplasmic hybrid cell line TC-HSMAM1, which contains the m.15059G>A mutation in mtDNA, was used. The MitoCas9 vector was utilized to eliminate mtDNA copies carrying the m.15059G>A mutation from TC-HSMAM1 cybrids. Mitochondrial membrane potential, generation of reactive oxygen species, and lipid peroxidation levels were assessed using flow cytometry. Cellular reduced glutathione levels were assessed using the confocal microscopy. The oxygen consumption rate was measured using polarographic oxygen respirometry.

The elimination of the m.15059G>A mutation resulted in a significant increase in mitochondrial membrane potential and improved mitochondrial efficiency while also causing a decrease in the generation of reactive oxygen species, lipid peroxidation, as well as cellular bioenergetic parameters, such as proton leak and non-mitochondrial oxygen consumption. At the same time, no changes were found in the intracellular antioxidant system after the mitochondrial genome editing.

The presence of the m.15059G>A mutation contributes to mitochondrial dysfunction by reducing mitochondrial membrane potential, increasing the generation of reactive oxygen species and lipid peroxidation, and altering mitochondrial bioenergetics. Elimination of the mtDNA containing atherogenic mutation leads to an improvement in mitochondrial function.

Aspergillus fumigatus, a significant fungal pathogen, poses a threat to human health, especially in immunocompromised individuals. Addressing the need for novel antifungal strategies, this study employs virtual screening to identify potential inhibitors of Fructosamine oxidase, also known as Amadoriase II, a crucial enzyme in A. fumigatus (PDB ID: 3DJE).

Virtual screening of 81,197 triazole derivatives was subjected to computational analysis, aiming to pinpoint molecules with high binding affinity to the active site of Fructosamine oxidase. Subsequently, an in-depth ADMET analysis assessed the pharmacokinetic properties of lead compounds, ensuring their viability for further development. Molecular dynamics simulations were performed to evaluate the stability of top-ranked compounds over time.

The results unveil a subset of triazole derivatives displaying promising interactions, suggesting their potential as inhibitors for further investigation.

This approach contributes to the development of targeted antifungal agents, offering a rational starting point for experimental validation and drug development against Aspergillus fumigatus infections.
