125-16) mu g/mL for fluconazole, 0.25
(0.0313-4) mu g/mL for itraconazole, and 4 (0.125-8) mu g/mL for flucytosine. Fluconazole, itraconazole, and flucytosine have excellent in vitro activity against all tested clinical Cryptococcus spp., and we also found a high rate of tolerance to amphotericin B (MICs ranging from 0.55-1 mu g/mL). Furthermore, C. neoformans isolates from acquired immune deficiency syndrome (AIDS) patients were less susceptible to fluconazole and flucytosine than those from non-AIDS patients. These data suggest that use of amphotericin B may lead to tolerance or resistance of the pathogen over time. There were also no significant associations between species, genotypes, and in vitro susceptibilities of these clinical isolates. (C) 2012 Elsevier Editora Ltda. All rights reserved.”
“Objective: selleck chemicals llc AZD3965 Transmembrane Transporters inhibitor Papillary thyroid carcinoma (PTC) is the most frequent types of thyroid malignancies. Several genes may be involved in susceptibility of thyroid cancer including Human Leukocyte Antigens (HLA). The association of
thyroid carcinoma with HLA alleles has been previously studied in other populations and certain HLA alleles were shown to be either predisposing or protective. The aim of this study was to determine the association between HLA-DR and papillary thyroid carcinoma in an Iranian population.
Design: HLA-DR antigen frequencies were determined in patients with papillary thyroid carcinoma (N = 70) and non-related healthy controls (N = 180) using PCR-SSP.
Main Outcome: We found that HLA-DRB1*04 frequency was significantly higher in our patients compared to the controls [P = 0.02, OR; 1.9, 95% CI (1.04-3.57)].
Conclusions: Our results revealed HLA-DRB1*04 as predisposing factor in papillary thyroid carcinoma in Iranian population. This confirms the previous findings for associations between HLA-DRB1 and differentiated carcinomas in other populations.”
“Objective: The purpose of this study was to determine the prevalence of Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) in patients with preterm labor or preterm premature rupture of membranes (PPROM) and to determine the effect of these organisms on pregnancy
outcomes based on the density of colonization.
Methods: The study group consisted of 184 women with preterm labor or PPROM. Vaginal buy Compound C cultures for UU and MH were performed for all patients at admission, and the placentas were histologically evaluated after delivery.
Results: The prevalence of positive vaginal fluid cultures for genital mycoplasma was 62.5% (112/179). This group included 99 patients carrying only UU and 13 carrying both organisms. No patients were found to carry only MH. Compared to patients only positive for UU, patients with both organisms showed significantly decreased gestational age at birth and birth weight, and significant increases in the incidences of preterm birth, NICU admissions and histologic chorioamnionitis.
