Thirty female virgin Wistar albino rats were randomly assigned to three groups: one control group and two acephate treatment groups.

Combinatory Use of hLF(1-11), a Synthetic Peptide Derived from Human Lactoferrin, and Fluconazole/Amphotericin B against Reveals a Synergistic/Additive Antifungal Effect.

Objective: The increasing resistance of yeasts against commonly used antifungal drugs dictates the need for novel antifungal compounds. Human lactoferrin-based peptides show a broad spectrum of antimicrobial activities. Various assays were performed to find the optimal growth conditions of the yeasts and to assess cell viability, using media with low lipid content to avoid peptide binding to medium components.

Autophagy and Female Fertility: Mechanisms, Clinical Implications, and Emerging Therapies.

Autophagy, an evolutionarily conserved cellular mechanism essential for maintaining internal stability, plays a crucial function in female reproductive ability. In this review, we discuss the complex interplay between autophagy and several facets of female reproductive health, encompassing pregnancy, ovarian functions, gynecologic malignancies, endometriosis, and infertility. Existing research emphasizes the crucial significance of autophagy in embryo implantation, specifically in the endometrium, highlighting its necessity in ensuring proper fetal development.

Several lines of antioxidant defense against oxidative stress: antioxidant enzymes, nanomaterials with multiple enzyme-mimicking activities, and low-molecular-weight antioxidants.

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are well recognized for playing a dual role, since they can be either deleterious or beneficial to biological systems. An imbalance between ROS production and elimination is termed oxidative stress, a critical factor and common denominator of many chronic diseases such as cancer, cardiovascular diseases, metabolic diseases, neurological disorders (Alzheimer's and Parkinson's diseases), and other disorders. To counteract the harmful effects of ROS, organisms have evolved a complex, three-line antioxidant defense system.

Reactive oxygen species, toxicity, oxidative stress, and antioxidants: chronic diseases and aging.

A physiological level of oxygen/nitrogen free radicals and non-radical reactive species (collectively known as ROS/RNS) is termed oxidative eustress or "good stress" and is characterized by low to mild levels of oxidants involved in the regulation of various biochemical transformations such as carboxylation, hydroxylation, peroxidation, or modulation of signal transduction pathways such as Nuclear factor-κB (NF-κB), Mitogen-activated protein kinase (MAPK) cascade, phosphoinositide-3-kinase, nuclear factor erythroid 2-related factor 2 (Nrf2) and other processes. Increased levels of ROS/RNS, generated from both endogenous (mitochondria, NADPH oxidases) and/or exogenous sources (radiation, certain drugs, foods, cigarette smoking, pollution) result in a harmful condition termed oxidative stress ("bad stress"). Although it is widely accepted, that many chronic diseases are multifactorial in origin, they share oxidative stress as a common denominator.

Time-dependent changes in the glycolytic pathway in activated T cells are independent of tumor burden or anti-cancer chemotherapy.

Using autophagy, apoptosis, cytoskeleton, and epigenetics markers to investigate the origin of infertility in ex-fissiparous freshwater planarian individuals (nomen nudum species) with hyperplasic ovaries.

The origin of the sterility observed in ex-fissiparous freshwater planarians with hyperplasic ovaries has yet to be explained. To improve our understanding of this enigmatic phenomenon, immunofluorescence staining and confocal microscopy examination were used the assess autophagy, apoptosis, cytoskeleton, and epigenetics markers in the hyperplasic ovaries of ex-fissiparous individuals and the normal ovaries of sexual individuals. Immunofluorescence positivity for the autophagic marker microtubule-associated protein 1 light chain 3 (LC3) was significantly lower in the hyperplasic ovary than in the normal ovary.
