Genotype‐Specific Small EVs Released by Giardia lamblia Act as Mediators of Phenotypic Adaptation Under Metronidazole‐Induced Stress

Journal of Extracellular Vesicles
Giardia lamblia, a eukaryotic intestinal parasite, produces small extracellular vesicles (sEVs) as a conserved evolutionary mechanism. This study investigates the functional role of sEVs in modulating drug response traits among G. lamblia parasites. Here,

Extended HPV typing as an efficient alternative within HPV‐based screening programs

International Journal of Cancer, EarlyView.
What's New? Extended high‐risk human papillomavirus (hrHPV) typing holds promise for improving cervical intraepithelial neoplasia grade 3 (CIN3) detection, particularly as vaccinated cohorts may shift the prevalence of oncogenic HPV types. The authors of this study evaluated extended hrHPV genotyping within a public screening program involving women ...

Tinnitus, medial olivocochlear system and music exposure in adolescents [PDF]

, 2017
The most common cause of tinnitus is the exposure to noise; in the case of adolescents, music is the main sound source they are exposed to. Currently, one of the hypotheses about the genesis of tinnitus is related to the deterioration in the functioning ...

Random Chemostats with Competition and Different Kinetics to Investigate the Growth of the Gut Microbiome

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We investigate some chemostat models incorporating wall growth, competition, random fluctuations on the dilution rate, and different consumption functions (Monod and Haldane). We analyze the asymptotic behavior of the solutions of the corresponding random differential systems to establish conditions on the model parameters under which the ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native
