background: as condition and component of culture determine fate map of spermatogonial stem cells (sscs), the aim of this study was to evaluate of growth factors gdnf, lif and ra on proliferation and differentiation of ssc. materials and methods: sscs were cultured in two groups: the first group gdnf and lif and the second group ra. the number of clumps and colony formation was monitored during...

in this study, invitro evaluation of some iranian plants against staphylococcus aureus isolation of urinary tract infection by microtiterplate method. all 12 strains of staphylococcus aureus isolated from urine culture of hospitalized patients during the years 2012- 2013. minimum inhibitory concentration (mic) of plant extract and essential oilagainst bacteria were determined using micro diluti...

cytokines influence cell cycle events, which in some but not all instances can be associated with melanoma progression. analysis of the g0/g 1 and s phase fractions of the cell cycle was used to assay the proliferative or inhibitory activity of cytokines against ten human melanoma cell lines, including pairs of cell lines derived from primary and metastatic tissue of individual patients. cytoki...

conclusions the average value of the vancomycin mic for isolates from mrsa colonized patients was 2 µg/ml. trimethoprim /sulfamethoxazole was the second most effective anti-mrsa oral antibiotic in vitro. patients and methods from november 2009 to march 2011, a prospective study was performed in two emergency departments. patients at high risk for mrsa colonization were identified, and mrsa surv...

conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...

Cortical neurons in vivo may operate in high-conductance states, in which the major part of the neuron's input conductance is due to synaptic activity, sometimes several-fold larger than the resting conductance. We examine here the contribution of inhibition in such high-conductance states. At the level of the absolute conductance values, several studies have shown that cortical neurons in vivo...

conclusions p. aeruginosa and s. marcescens can be good candidates for the detoxification of cr (vi) in soltan abad river. results the results indicated that pseudomonas aeruginosa and serratia marcescens were the most resistant bacteria with mics of 200 and 150 mg/l, respectively. both bacteria completely reduced 25 and 50 mg/l of cr (vi) in 36 hours and 48 hours, respectively. the growth rate...
