BACKGROUND Peritoneal dialysis fluid (PDF) containing amino acids has been introduced recently aiming to improve the nutritional status of PD patients. Dextrose-based PDFs have been implicated in progressive functional and structural deterioration of the peritoneal membrane. Limited data are currently available regarding the effect of amino acid-based PDF on the function and ultrastructure of h...

surface topography and ultrastructure of dried cysts of artemia parthenogenetica (vedaranyam population) and bisexual artemia sp. (kelambakkam population) were studied electron microscopically in order to identify the bisexual strain, inhabiting covelong salterns, kelambakkam, south india. the scope of this study is to provide substantial information for further characterization of these artemi...
Abstract The thermal reactivities of cellulose and hemicellulose are significantly different in cell walls when compared with isolated components differ Japanese cedar (softwood) beech (hardwood). Uronic acid bound to xylan promotes the degradation hemicellulose, its effect is depending on form free (acting as an catalyst) or metal uronate a base catalyst). We evaluated location uronic wall by ...
The first cell of an animal (zygote) requires centrosomes that are assembled from paternally inherited centrioles and maternally inherited pericentriolar material (PCM) [1]. In some animals, sperm centrioles with typical ultrastructure are the origin of the first centrosomes in the zygote [2-4]. In other animals, however, sperm centrioles lose their proteins and are thought to be degenerated an...
