Infertility is increasingly recognized as being closely linked to obesity in humans. The successful production of fertile spermatozoa requires adequate spermatogenesis within the testis and proper maturation through epididymis. This study aimed evaluate impact body adiposity on male fertility, focusing sperm parameters, epididymal maturation, capacitation Wistar rats. Male rats were randomized into three dietary groups over four weeks: a control group receiving less than 4% lard, regular...
ABSTRACT Various toxic agents are associated with male infertility, including perfluoroalkyl substances (PFAS), which emerging as significant contributors due to their physico‐chemical properties that exhibit a propensity for bioaccumulation and potentially pose reproductive risks. The aim of this study was analyse the effects perfluorooctane sulphonate (PFOS) perfluorooctanoic acid (PFOA) on boar spermatozoa during capacitation through focus agglutinate formation. A second objective assess...
1.Abstract Diarrheal diseases remain a significant global health challenge, particularly in developing regions such as Africa, Asia, and Latin America, where they are leading cause of child mortality. Contaminated food, including raw or undercooked vegetables, is major transmission route for diarrheal pathogens norovirus, Campylobacter, non-typhoid Salmonella, pathogenic Escherichia coli. This study aimed to assess the prevalence enterotoxigenic coli (ETEC), key pathogen, fresh produce...
ABSTRACT Several focal adhesion proteins are known to cooperate with integrins link the extracellular matrix actin cytoskeleton; as a result, many intracellular signaling pathways activated and several complexes formed. However, how these function in mammalian spermatozoa remains unknown. We confirm presence of guinea pig spermatozoa, we explore their role during capacitation acrosome reaction, relationship cytoskeleton. Our results suggest complex formed by β1-integrin, kinase (FAK),...
The one- and two-dimensional protein patterns of Streptococcus thermophilus PB18 in the exponential stationary phases growth were analysed. Onedimensional SDS-PAGE showed that a 16 kDa was overexpressed phase as well 2 h after an acid shock, it not expressed when bacteria reached medium with limiting lactose concentrations (5 or 10 g l -1 ), which pH (5∙5) control cultures (pH 4∙7, 20 ). results support idea this is response to acidic environment phase. Two-dimensional PAGE nine proteins...
Malathion is one of the most commonly used insecticides. Recent findings have demonstrated that it induces oxidative stress in somatic cells, but there are not enough studies this effect germ cells. impairs porcine oocyte viability and maturation, shown how damages maturation which biochemical mechanisms affected process cumulus-oocyte complexes (COCs). The aims present study were to determine amount produced by malathion COCs matured vitro, define affect process, whether trolox can...
Perfluorooctane sulfonate (PFOS) and perfluorohexane (PFHxS) are toxic bioaccumulative, included in the Stockholm Convention's list as persistent organic pollutants. Due to their toxicity, worldwide distribution, lack of information spermatozoa physiology during pre-fertilization processes, present study seeks analyze effects possible alterations caused by presence these compounds boar sperm vitro capacitation. The capacitation was performed supplemented TALP-Hepes media mean lethal...
Malnutrition is distributed widely throughout the world and a particular problem in developing countries. Laboratory animals have been very useful studying effects of varying levels malnutrition because non-nutritional factors that affect humans may be controlled. The objective present study was to determine moderate severe on lymphocyte proportions activation markers T cells experimentally malnourished rats during lactation by flow cytometry. Lower absolute (total) relative (%) numbers CD3+...
Poor endometrial quality is associated with more than a third of embryo implantation failures. Current ultrasonography technology lacks the capacity to determine efficiently receptivity during ongoing cycle transfers. We analyzed relationship between gene expression profile and clinical pregnancy from cells taken transfer.Seventy-six patients submitted standard ovarian stimulation protocol, in vitro fertilization, good embryos were collected (morphological assessment). Endometrial samples...
Atrazine is a herbicide of the chloro-s-triazine family. It inhibits photosynthesis in plants and an endocrine disruptor, but its effects on human health are controversial. Fenoxaprop-ethyl, aryloxy phenoxyalkanoic acid herbicide, biosynthesis fatty acids provokes depolarization membranes. The aim this study to evaluate vitro both herbicides capacitation, spontaneous acrosome reaction (SAR) progesterone-induced (PIAR) boar sperm. Sperm capacitation done TALP-HEPES media for 4 hours....
Chlorophenols are widely distributed in the environment. Various strategies have been used to improve their biological elimination under anaerobic conditions; however, such information is still scarce. The aim of this study was evaluate batch assays consumption 2-chlorophenol (2-CP) by a denitrifying sludge and influence acetate or phenol as co-substrates 2-CP consumption. It observed that (69 92 mg phenol-C L−1) (60 108 acetate-C enhanced sludge, increasing both efficiency (up 100%)...
Studies suggest that carbohydrates are important in different stages of fertilization. Plasma membrane changes accompanying vitro capacitation and acrosome reaction (AR), such as removal or appearance specific glycoproteins, have been studied using lectins bind specifically to carbohydrate residues. In specialized artificial insemination farms semen production centers, identification boars with decreased fertilization ability (subfertility) is a newborn necessity. This investigation...
