Pneumonia may involve methicillin-resistant Staphylococcus aureus (MRSA), with elevated rates of antibiotics failure. The present study aimed to assess the effect of statins given prior to pneumonia development. Spontaneously breathing (SB) or mechanically ventilated (MV) rabbits with pneumonia received atorvastatin alone, linezolid (LNZ) alone, or a combination of both (n = 5 in each group). Spontaneously breathing and MV untreated infected animals (n = 11 in each group), as well as uninfected animals (n = 5 in each group) were used as controls...

The migration of metals and metalloids between bottom sediments and water and the other way round is a complex process. Understanding those mechanisms is essential for recognizing transformations taking place in water reservoir ecosystems. The objective behind the following study was to define time and spatial correlations in the changes in total concentrations of selected elements (Cr, Zn, Co, Mn, Cu, Ni, Pb, As, Ba, Sb, Sr and V) in waters and bottom sediments from two water reservoirs located in Upper Silesia (Poland), i...

SCOPE: Glycyrrhiza uralensis extract (GUE) has been reported to improve amyloid beta (Aβ) induced cognitive deficits in mice. However, the mechanisms underlying this effect and the components involved have not been previously explored. Extracellular Aβ plaques are one of the major pathological hallmarks of Alzheimer's disease (AD). Therefore, decreasing Aβ levels is one strategy for preventing the etiology of AD. This study aimed to test the effect of GUE and semilicoisoflavone B (SB) on Aβ secretion and investigate the mechanism underlying this effect...

OBJECTIVE: Results of published studies on the association between sedentary behavior (SB) and obesity are inconsistent, possibly due to reliance on subjective measures of SB and inappropriate measures of obesity. The aim of this study was to examine the relationship between objectively measured SB and criterion-measured obesity among adults. METHODS: A total of 2284 adults (≥18 years) from the 2003 to 2004 National Health and Nutrition Examination Survey were included in the analysis...

The amount of time spent in sedentary behaviors (SB) progressively increases with age, while reducing time spent in light (LPA) and moderate-to-vigorous physical activity (MVPA). These trajectories in PA and SB are linked to accelerated reductions in physical functioning. PURPOSE: To examine the association of substituting SB time with LPA and MVPA on physical function in older adults. METHODS: Ninety-one older adults (mean age: 70.7 ± 10.2 yr) wore a hip-mounted accelerometer to measure SB, LPA, and MVPA time...

We have performed a systematic parallel field magnetotransport studies of (Bi1-x Sb x )2Te3 to understand the temperature and impurity effect on the interference of bulk conductance on the surface states of highly insulating topologically insulating compound Bi2Te3. The compound exhibits a weak antilocalization effect (WAL) at low temperature and low magnetic field. WAL weakens and a weak localization effect is observed to be developed in the compound with the increase in temperature due to the creation of topologically trivial 2D electron gas states...

A novel extraction method was developed, optimized and validated for the elemental analysis of organic samples. The method, called aerosol phase extraction (APE), was based on the nebulization of the extracting aqueous solution (0.1 mol L-1 nitric acid) on the sample. The extraction was performed at the interface of each generated extractant droplets as they entered in contact with the samples. Afterwards, the phases were allowed to separate and Ca, K, Na and Mg were determined in aqueous phase by means of inductively coupled plasma optical emission spectroscopy (ICP-OES)...

Knowledge about chemical functionalization is of fundamental importance to design novel two-dimensional topological insulators. Despite theoretical predictions of quantum spin Hall effect (QSH) insulator via chemical functionalization, it is quite challenging to obtain a high-quality sample, in which the toxicity is also an important factor that cannot be ignored. Herein, using first-principles calculations, we predict an intrinsic QSH effect in amidogen-functionalized Bi/Sb(111) films (SbNH2 and BiNH2), characterized by nontrivial Z2 invariant and helical edge states...
