The effects of estrogen and progestogen treatment on the response of the thoracic aortic wall of male rats to hypertension were studied. Hypertension levels induced by cupping the renal artery were similar in untreated (H), estrogen-treated (E), and progestogen-treated (P) hypertensive groups. Hypertension of 8 weeks' duration caused increased wall thickness, increased calculated tangential ten...

background: hearing loss due to chronic otitis media is common. the purpose of this study was to evaluate hearing before and after canal wall up, canal wall down mastoidectomy and tympanoplasty. methods: from 2004 to 2007, all patients with chronic otitis media who were admitted at the department of otolaryngology, babol medical university were studied. for 126 patients' canal wall up, can...

The changes in cell morphology of Bacillus subtilis rodB during a temperature shift from 20 to 42 degrees C, in the absence of added anions, are described. At 20 degrees C the organisms grow as rods but gradually become spherical in shape when placed at 42 degrees C. The shape change is initiated by an increase in diameter at the cell equator, resulting in a bulged morphology, which is further ...

The aim of this study was to investigate the immunomodulatory properties of cell wall extract from Enterococcus faecalis CECT7121, measuring the induction of cytokines TNF-α, IL-6, IL-10 and IL-12 from human peripheral blood mononuclear cells (PBMCs). Cell wall extract was prepared from their growth in brain heart infusion broth (18h, 35°C). Subsequently, toxicity of the obtained cell wall extr...

The ability of cells to perceive changes in the composition and mechanical properties of their cell wall is crucial for plants to achieve coordinated growth and development. Evidence is accumulating to show that the plant cell wall, like its yeast counterpart, is capable of triggering multiple signalling pathways. The components of the cell wall that are responsible for initiating these signal ...

We tested the ability of an ultraviolet C (UV-C)-reflective wall coating to reduce the time necessary to decontaminate a room using a UV-C-emitting device (Tru-D SmartUVC). The reflective wall coating provided the following time reductions for decontamination: for methicillin-resistant Staphylococcus aureus, from 25 minutes 13 seconds to 5 minutes 3 seconds ([Formula: see text]), and for Clostr...

BACKGROUND Early detection in patients with hypertrophic cardiomyopathy (HCM) is very important. Integrated backscatter (IB) provides a useful noninvasive measure of the acoustic properties of the myocardium, and may detect early myocardial changes. METHODS Thirty-four carriers who had gene mutations causing HCM were studied. The patients were divided into three groups as follows: (1) 21 pati...

the aim of this study was to identify various sulfidic mineralized zones in the ghare-tappeh cu deposit (nw iran) based on geo-electrical data including induced polarization (ip) and resistivity (rs) using the concentration-volume (c-v) and number-size (n-s) fractal models. the fractal models were used to separate high and moderate sulfidic zones from low sulfidic zones and barren wall rocks. b...
