Bali cattle are the indigenous well known attributed to their high fertility. Various proteomes in sperm substances that can determine quality and One of which is alpha enolase (ENO1). This study aims assess presence ENO1 plasma membrane its relationship with semen cattle. The used 30 ejaculates from 5 bulls for assessment detection ENO1. Sperm indicated by total motility, progressive kinematic...
Background: Formaldehyde (FA) is a member of aldehyde family with a simplest organic molecule, used in various industries. Since there is simultaneous exposure of formaldehyde and noise for workers in most of the workplaces and that noise can reinforce the harmful effects of some chemical pollutants. This study aimed to investigate the effects of simultaneous formaldehyde and noise exposure on ...
Background: Basal level of reactive oxygen species (ROS) is essential for sperm acrosomal reaction, hyperactivation, motility, capacitation and fertilization. Ram spermatozoa contain large quantities of polyunsaturated fatty acids in their plasma membranes so are extremely susceptible to ROS induced damage. Materials and Methods: Eight rams (36 ± 5 month of age and with a weight of 64 ± 7 kg) w...
Background: The lipid peroxides and their degradation products are highly toxic to spermatozoa and may play a major role in sperm dysfunction. The purpose of this study was to determine the level of lipid peroxidation as indicated by malondialdehyde (MDA) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males. In addition, correlation of lipid peroxidation with mot...
This study investigated the effect of spirulina ethanolic extract (SEE) on quality ram semen during low-temperature liquid storage and relationship between sperm features. Ejaculates were collected from five Djallonké rams, pooled, extended with Tris-egg yolk (TEY) enriched 0 (control), 20 (SEE20), 40 (SEE40), 80 µg/mL (SEE80) SEE to reach concentration 200×106 spz/mL, stored at 4 °C for 72 h. ...
The growth of the organs of human embryo is changing significantly over a short period of time in the mother body. The shape of the human organs is organic and has many folds that are difficult to model or animate with conventional techniques. Convolution surface and function representation are a good choice in modelling such organs as human embryo stomach and brain. Two approaches are proposed...
AIM To investigate the distribution of cation channel of sperm 1 (CATSPER1) protein and the presence of CATSPER1 mRNA in human testis and ejaculated spermatozoa. The influence of anti-human CATSPER1 antibody upon human sperm motility was used to evaluate the function of human CATSPER1 and to estimate its possible use as a target for immunocontraception. METHODS Human ejaculated sperm from nor...
