This study investigated the impact of an increased arginine (ARG) level in a boar diet on semen production, sperm quality, and seminal plasma proteome. Adult Nebraska Index Line boars were assigned to two groups, one receiving control with 0.77% (n = 4) other high-arginine 1.77% 5). Semen was collected twice week over whole experiment, including before, six weeks during, after supplementation. Parameters such as volume concentration assessed immediately collection, alongside motility...

Sperm heterogeneity creates challenges for successful artificial insemination. Seminal plasma (SP) surrounding sperm is an excellent source detecting reliable non-invasive biomarkers of quality. Here, we isolated microRNAs (miRNAs) from SP-derived extracellular vesicles (SP-EV) boars with divergent quality statuses. Raw semen sexually mature was collected eight weeks. motility and normal morphology were analyzed, the classified as poor- or good-quality based on standard cutoffs 70%...

<h3>Objectives:</h3> Human papillomavirus (HPV) infection is closely associated with the development of more than 95% cervical cancer. Clinical trials using several chemopreventive agents are underway, but results inconclusive. Most used in inhibited growth cancer cells vitro, and about half patients had some degree clinical responses; however, therapeutic effect was confounded by high rates spontaneous regression relapse.

Various obstacles are encountered by mammalian spermatozoa during their journey through the female genital tract, and only few or none will reach site of fertilization. Currently, there limited technical approaches for non-invasive investigation migration after insemination. As knowledge surrounding sperm behavior throughout tract still remains elusive, recent development self-illuminating quantum dot nanoparticles may present a potential means real-time in vitro vivo monitoring...

There is a clear need for low-cost, self-applied, long-lasting approaches to prevent human immunodeficiency virus (HIV) infection in both men and women, even with the advent of pre-exposure prophylaxis (PrEP). Broadly neutralizing antibodies represent an option improve HIV prophylaxis, but intravenous delivery, cold-chain stability requirements, low cervicovaginal concentrations, cost may preclude their use. Here, we present approach express anti-GP120 broadly antibody PGT121 primary site...

Nanoparticles have emerged as key materials for developing applications in nanomedicine, nanobiotechnology, bioimaging and theranostics. Existing technologies include bioluminescent resonance energy transfer-conjugated quantum dots (BRET-QDs). Despite the current use of BRET-QDs bioimaging, there are strong concerns about QD nanocomposites containing cadmium which exhibits potential cellular toxicity. In this study, composites comprised magnetic nanoparticles firefly luciferase (Photinus...

The protective effect of natural products such as fruits and vegetables against cancer has attracted great attention because their fewer side effects therefore, potentially greater safety. We have previously reported that cactus pear mixture aqueous extract (CME) reduces gynecologic cells growth by inducting apoptosis. This study aimed to elucidate the cellular pathway(s) triggered CME in cells. Normal, immortalized ovarian (OVCA420, SKOV3) were treated with 5 10% CME. After 2 days...
