background: human sperm cryopreservation has proven to be very valuable. cryopreservation has effects on function, morphology and percentage of fertilization capacity of human sperm. also, it has been revealed that cryopreservation has a role in sperm dna fragmentation and infertility. in this study, viability, motility, dna fragmentation and for the first time, intracellular nitric oxide asses...
background: curcumin has shown to affect sperm motility and function in vitro and fertility in vivo. the molecular mechanism(s) by which curcumin affects sperm motility has not been delineated. since modulation of intracellular ph (phi) and plasma membrane polarization is involved in sperm motility, the present study was conducted to investigate the effect of curcumin on these sperm (human and ...
Transport into/out of subcellular compartments such as the nucleus is central to many important biological processes. In recent decades, significant advances in the development of fluorescent proteins has led to the development of various techniques to examine the movement/diffusion of proteins in living cells, enabling quantitative kinetic data to be generated and facilitating insight into the...
Eukaryotic cells create internal order by using protein motors to transport molecules and organelles along cytoskeletal tracks. Recent genomic and functional studies suggest that five cargo-carrying motors emerged in primitive eukaryotes and have been widely used throughout evolution. The complexity of these "Toolbox" motors expanded in higher eukaryotes through gene duplication, alternative sp...
an in vitro study on the role of intracellular calcium ions in healing of excisional wound in rabbit was undertaken. we employed two drugs namely, glibenclamide and nitroglycerin that are topically applied in vivo to modulate the activity of intracellular calcium. our model consisted of a 15 ´ 15 mm excisional wound. seven groups of new zealand rabbits were used. the first three groups served a...
