Some hepatocellular adenoma (HCA) subtypes are characterized by different CTNNB1 mutations, leading to beta-catenin activation levels, hence variable immunostaining patterns of glutamine synthetase (GS) expression, and risks malignant transformation. In a retrospective multicentric study 63 resected inflammatory (n=33) noninflammatory (n=30) molecularly confirmed CTNNB1-mutated b-(I)HCA, we inv...
BACKGROUND The aim of this study was to identify factors predicting histologic chorioamnionitis (HCA) in women with preterm premature rupture of membranes (PPROM). MATERIAL AND METHODS We retrospectively enrolled 371 women diagnosed with PPROM at less than 34 weeks of gestation at the Second Affiliated Hospital of Wenzhou Medical University between January 2008 and December 2012. HCA was diag...
BACKGROUND Healthcare-associated (HCA) infection has emerged as a new epidemiological category. The aim of this study was to evaluate the impact of HCA infection on mortality in community-onset Klebsiella pneumoniae bloodstream infection (KpBSI). METHODS We conducted a retrospective study in two tertiary-care hospitals over a 6-year period. All adult patients with KpBSI within 48 hours of adm...
بارهای تک‌فاز با الگوی مصرفی متفاوت، عمده بارهای شبکه‌های توزیع فشارضعیف را تشکیل می‌دهند و با گسترش استفاده از ادوات الکترونیک_قدرت در تجهیزات الکتریکی بار مشترکین در اکثر شبکه‌های توزیع فشارضعیف علاوه‌بر عدم تعادل، دارای اعوجاجات هارمونیکی هست. این عدم تعادل و اعوجاجات هارمونیکی نه تنها به شبکه‌های بالادست منتقل شده و باعث بروز مشکل می‌شوند، بلکه در شبکه‌های فشارضعیف نیز موجب می‌شود تا مجموع ...
background and objectives: attenuated total reflectance-inferared (atr-ir) spectra can be used as a non-invasive fingerprinting approach in quality control of herbal samples. methods: twenty versatile herbal samples were subjected to attenuated total reflectance-inferared (atr-ir) spectroscopy followed by different clustering methods in order to determine by which method more reasonable classif...
BACKGROUND Hepatocellular adenoma (HCA) in pregnant women requires special considerations because of the risk of hormone induced growth and spontaneous rupture, which may threaten the life of both mother and child. Due to scarcity of cases there is no evidence-based algorithm for the evaluation and management of HCA during pregnancy. Most experts advocate that women with HCA should not get preg...
We characterized the cardiovascular responses to forearm muscle metaboreflex activation during hypercapnia. Ten healthy males participated under three experimental conditions: 1) hypercapnia (HCA, PetCO2 : +10 mmHg, by inhalation of a CO2-enriched gas mixture); 2) muscle metaboreflex activation (MMA, by 5 min of local circulatory occlusion after 1 min of 50% maximum voluntary contraction isomet...
Hypercapnic acidosis (HCA) has beneficial effects in experimental models of lung injury by attenuating inflammation and decreasing pulmonary edema. However, HCA increases pulmonary vascular pressure that will increase fluid filtration and worsen edema development. To reconcile these disparate effects, we tested the hypothesis that HCA inhibits endothelial mechanotransduction and protects agains...
OBJECTIVE To explore the relationship between prematurity, gender and chorioamnionitis as determinants of early life lung function in premature infants. METHODS Placenta and membranes were collected from preterm deliveries (<37 weeks gestational age) and evaluated for histological chorioamnionitis (HCA). Patients were followed and lung function was performed in the first year of life by Raise...
