MicroRNAs (miRNAs) have appeared as important regulators of various biological processes including development, cancer, immunity, and host-microorganism interactions. Accumulating evidence demonstrates the differential expression of host miRNAs upon infection by various microorganisms and the involvement of microorganism-encoded miRNAs in host manipulation. Some of these alterations could be pa...

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) ...

background petroleum reservoirs have long been known as the hosts of extremophilic microorganisms. some of these microorganisms are known for their potential biotechnological applications, particularly production of extra and intracellular polymers and enzymes. objectives here, 14 petroleum liquid samples from southern iranian oil reservoirs were screened for presence of biosurfactant‐producing...

2010 had distinct random amplifi ed patterns that differed from those generated from isolates A–G (Figure). A previous study in Taiwan showed that the incidence (no. cases/100,000 inpatients and outpatients) of all pulmonary disease caused by NTM increased signifi cantly from 2.7 (1.26) in 2000 to 10.2 (7.94) in 2008 (6). The most common organism in localized pulmonary infection and disseminate...

BACKGROUND Haemophilus influenzae is the most common colonizing bacteria of the bronchial tree in chronic obstructive pulmonary disease (COPD), and positive cultures for this potentially pathogenic microorganism (PPM) has been associated with local inflammation changes that may influence the relationships between H. influenzae and the bronchial mucosa. METHODS A cross-sectional analysis of st...
