enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (sscs) transplantation. knock-out serum replacement (ksr) has been reported to enhance the proliferation of murine sscs and human embryonic stem cells. the aim of the present study was to investigate the effect of ksr versus fetal bovine serum (fbs) ...

to improve our understanding of helicobacter  infection in cats and to determine whether they are reservoirs for h. pylori  and sources of zoonotic transmission to humans, we selected cats as an experimental animal model for gastric colonization by h. pylori. sixteen stray cats underwent helicobacter  eradication treatment followed by three consecutive oral inoculations of a cocktail of human h...

For us neonatologists, research about necrotizing enterocolitis always incites great curiosity, because our understanding of its physiopathology is largely speculative, and this illness haunts the neonatal intensive care unit. Nowadays, as viability increases, the prevalence of necrotizing enterocolitis is becoming more important because we are taking care of more immature and lower birth-weigh...

Streptococcus agalactiae or group B streptococcus (GBS) is a leading cause of serious neonatal infections. GBS is an opportunistic commensal constituting a part of the intestinal and vaginal physiologic flora and maternal colonization is the principal route of GBS transmission. GBS is a pathobiont that converts from the asymptomatic mucosal carriage state to a major bacterial pathogen causing s...

Background and Aims: Nasal Colonization with Methicillin Resistant Staphylococcus aureus (MRSA) is known as an important risk factor in the development of dangerous infections. Materials and Methods: The present study seeks to investigate the prevalence of MRSA nasal colonization among the preschool and school children under 14 in Urmia. To do so, specimens for culture were obtained fro...
