Objective:
The accuracy of anthropometric surrogate markers such as the body adiposity index (BAI) and other common indexes like the body mass index (BMI), waist‐to‐hip ratio (WHR) and waist‐to‐height ratio (WHtR) to predict metabolic sequelae is essential for its use in clinical practice.Design and Methods:
Thus, we evaluated the strength of BAI and other indexes to relate with anthropometric parameters, adipocytokines, blood lipids, parameters of glucose‐homeostasis and blood pressure in 1,770 patients from the Salzburg Atherosclerosis Prevention Program in Subjects at High Individual Risk (SAPHIR) study in a crosssectional design. Measurements were BAI, BMI, WHR, WHtR, abdominal subcutaneous and visceral adipose tissue (aSAT and VAT), total body adipose tissue mass, body weight, waist‐ and hip circumference (WC and HC), leptin, adiponectin, high‐density lipoprotein‐cholesterol (HDL‐C), low‐density lipoprotein‐cholesterol (LDL‐C), triglycerides (TG), fasting plasma glucose, fasting plasma insulin, the homeostasis model assessment of insulin resistance (HOMAIR), systolic and diastolic blood pressure.Results and Conclusions:
BAI was significantly associated with leptin and HC. We conclude that BAI was the best calculator for leptin. BAI was inferior to BMI to predict anthropometric parameters other than HC, adiponectin, blood lipids, parameters of glucose homeostasis, and blood pressure in this cross‐sectional study. 相似文献103.

High-throughput platforms facilitating screening campaigns of environmental samples are needed to discover new products of natural origin counteracting the spreading of antimicrobial resistances constantly threatening human and agricultural health. We applied a combination of droplet microfluidics and fluorescence-activated cell sorting (FACS)-based technologies to access and assess a microbial environmental sample. The cultivation performance of our microfluidics workflow was evaluated in respect to the utilized cultivation media by Illumina amplicon sequencing of a pool of millions of droplets, respectively. This enabled the rational selection of a growth medium supporting the isolation of microbial diversity from soil (five phyla affiliated to 57 genera) including a member of the acidobacterial subgroup 1 (genus Edaphobacter). In a second phase, the entire diversity covered by 1071 cultures was used for an arrayed bioprospecting campaign, resulting in > 6000 extracts tested against human pathogens and agricultural pests. After redundancy curation by using a combinatorial chemical and genomic fingerprinting approach, we assigned the causative agents present in the extracts. Utilizing UHPLC-QTOF-MS/MS-guided fractionation and microplate-based screening assays in combination with molecular networking the production of bioactive ionophorous macrotetrolides, phospholipids, the cyclic lipopetides massetolides E, F, H and serratamolide A and many derivatives thereof was shown. 相似文献

Candida albicans is an important opportunistic pathogen that can cause serious fungal diseases in immunocompromised patients including cancer patients, transplant patients, and patients receiving immunosuppressive therapy in general, those with human immunodeficiency virus infections and undergoing major surgery. Its emergence spectrum varies from mucosal to systemic infections and the first line treatment is still based on fluconazole, a triazole derivate with a potent antifungal activity against most of C. albicans strains. Nevertheless the emergence of fluconazole-resistant C. albicans strains can lead to treatment failures and thus become a clinical problem in the management of such infections. For that reason we consider it important to study mechanisms inducing azole resistance and the possibilities to influence this process. In this work we give a short report on a real-time PCR (TaqMan) assay, which can be used for quantitative analyses of gene expression levels of MDR1, CDR1 and ERG11, genes supposed to contribute to development of the resistance mechanisms. We show some results achieved with that assay in fluconazole susceptible and resistant strains that confirm results seen earlier in experiments using Northern blot hybridisation and prove that the comparative DeltaCt method is valid for our system. 相似文献

More than a quarter of a century ago, the phenomenon of glucocorticoid-induced apoptosis in the majority of hematological
cells was first recognized. More recently, glucocorticoid-induced antiapoptotic signaling associated with apoptosis resistance
has been identified in cells of epithelial origin, most of malignant solid tumors and some other tissues. Despite these huge
amount of data demonstrating differential pro- and anti-apoptotic effects of glucocortioids, the underlying mechanisms of
cell type specific glucocorticoid signaling are just beginning to be described. This review summarizes our present understanding
of cell type-specific pro- and anti-apoptotic signaling induced by glucocorticoids. In the first section we give a summary
and update of known glucocorticoid-induced pathways mediating apoptosis in hematological cells. We shortly introduce mechanisms
of glucocorticoid resistance of hematological cells. We highlight and discuss the emerging molecular evidence of a general
induction of survival signaling in epithelial cells and carcinoma cells by glucocorticoids. We provide a model for glucocorticoid-induced
resistance in cells growing in a tissue formation. Thus, attachment to the extracellular matrix and cell-cell contacts typical
for e.g. epithelial and tumor cells may be crucially involved in switching the balance of several interacting pathways to
survival upon treatment with glucocorticoids. 相似文献

In this study, we have studied the expression, localization, and functionality of vacuolar-type H+-ATPase (vH+-ATPase) and Na+/K+-ATPase in the bovine rumen epithelium. Compared with the intracellular pH (pHi) of control rumen epithelial cells (REC; 7.06 ± 0.07), application of inhibitors selective for vH+-ATPase (foliomycin) and Na+/K+-ATPase (ouabain) reduced pHi by 0.10 ± 0.03 and 0.18 ± 0.03 pH-units, respectively, thereby verifying the existence of both functional proteins. Results
from qRT-PCR and immunoblotting clearly confirm the expression of vH+-ATPase B subunit in REC. However, the amount of Na+/K+-ATPase mRNA and protein is tenfold and 11-fold of those of vH+-ATPase subunit B, respectively, reflecting a lower overall abundance of the latter in REC. Na+/K+-ATPase immunostaining has revealed the protein in the plasma membrane of all REC from the stratum basale to stratum granulosum,
with the highest abundance in basal cells. In contrast, the vH+-ATPase B subunit has been detected in groups of cells only, mainly localized in the stratum spinosum and stratum granulosum
of the epithelium. Furthermore, vH+-ATPase has been detected in the cell membrane and in intracellular pools. Thus, functional vacuolar-type H+ pumps are expressed in REC and probably play a role in the adaptation of epithelial transport processes. 相似文献

Summary: Nitrogenase catalyzes a key step in the global nitrogen cycle, the nucleotide-dependent reduction of atmospheric dinitrogen to bioavailable ammonia. There is a substantial amount of interest in elucidating the biosynthetic mechanisms of the FeMoco and the P-cluster of nitrogenase, because these clusters are not only biologically important but also chemically unprecedented. In this review, we summarize the recent advances in this research area, with an emphasis on our work that aims at providing structural and spectroscopic insights into the assembly of these complex metalloclusters. 相似文献

Estradiol and progesterone mediate their actions by binding to classical nuclear receptors, estrogen receptor α (ERα) and
estrogen receptor β (ERβ) and progesterone receptor A and B (PR-A and PR-B) and the non-classical G protein-coupled estrogen
receptor (GPER). Several animal knock-out models have shown the importance of the receptors for growth of the oocyte and ovulation.
The aim of our study was to identify GPER in human granulosa cells (GC) for the first time. Moreover, the effect of different
doses of gonadotropins on estrogen and progesterone receptors in the human ovary should be investigated as follicle stimulating
hormone (FSH) and luteinizing hormone (LH) are also responsible for numerous mechanisms in the ovary like induction of the
steroid biosynthesis. Human GC were cultured in vitro and stimulated with different doses of recombinant human FSH or LH.
Receptor expression was analyzed by immunocytochemistry and quantitative real-time RT-PCR. GPER could be identified for the
first time in human GC. It could be shown that high concentrations of LH increase GPER protein expression. Furthermore FSH
and LH increased ERβ, PR-A and PR-B significantly on protein level. These findings were verified for high doses of FSH and
LH on mRNA level. ERα was not affected with FSH or LH. We assume that gonadotropins induce GPER, ERβ and PR in luteinized
granulosa cells. 相似文献
