Chromium is a first row transition element in the periodic table. It may resembles the group 16 elements of the oxygen group but only in the acidity of the trioxide and in its covalent nature. Cr(III) with its d configuration forms thousands of inert complexes; an important characteristic of these complexes, in aqueous solutions, is their relative kinetic inertness. The radius of Cr(III) is 0.7...

For k-uniform hypergraphs F and H and an integer r ≥ 2, let cr,F (H) denote the number of r-colorings of the set of hyperedges of H with no monochromatic copy of F and let cr,F (n) = maxH∈Hn cr,F (H), where the maximum runs over the family Hn of all k-uniform hypergraphs on n vertices. Moreover, let ex(n, F ) be the usual Turán function, i.e., the maximum number of hyperedges of an n-vertex k-u...

Posttraumatic stress disorder (PTSD) is an anxiety- and memory-based disorder. The hippocampus and amygdala are key areas in mood regulation. Fluoxetine was found to improve the anxiety-related symptoms of PTSD patients. However, little work has directly examined the effects of fluoxetine on the hippocampus and the amygdala. In the present study, male Wistar rats received fluoxetine or vehicle ...

BACKGROUND Obesity associates with low-grade inflammation and adipose tissue remodeling. Using sensitive high-throughput protein arrays we here investigated adipose tissue cytokine and angiogenesis-related protein profiles from obese and lean mice, and in particular, the influence of calorie restriction (CR). METHODS Tissue samples from visceral fat were harvested from obese mice fed with a h...

Protonated or Ca-form Sargassum seaweed biomass bound up to 40 mg/g of Cr(III) by ion exchange at pH 4. An ion-exchange model assuming that the only species taken up by the biomass was Cr(OH)2+ successfully fitted the experimental biosorption data for Cr(III). The maximum uptake of Cr(VI) by protonated Sargassum biomass at pH 2 was explained by simultaneous anion exchange and Cr(VI) to Cr(III) ...

We present genome-wide microarray expression analysis of 11,000 genes in an aging potentially mitotic tissue, the liver. This organ has a major impact on health and homeostasis during aging. The effects of life- and health-span-extending caloric restriction (CR) on gene expression among young and old mice and between long-term CR (LT-CR) and short-term CR (ST-CR) were examined. This experimenta...

Background The presence of mental health conditions in cardiac rehabilitation (CR) patients such as anxiety and depression can lead to reduced programme adherence, increased mortality and increased re-occurrence of cardiovascular events undermining the aims and benefit of CR. Earlier research has identified a relationship between delayed commencement of CR and poorer physical activity outcomes....

A graph G is k-crossing-critical if cr(G)≥k, but cr(G∖e)<k for each edge e∈E(G), where cr(G) the crossing number of G. It known that latest upper bound a 2k+8k+47 when δ(G)≥3, and 2k+35 δ(G)≥4, δ(G) minimum degree In this paper, we mainly show any with n vertices, cr(G)≤2k+8 cr(G)≤2k−k/2n+35/6 δ(G)≥5.

Caloric restriction (CR) decreases circulating triiodothyronine (T(3)) concentration. However, it is not known if this effect is due to body fat mass reductions or due to CR, per se. The purpose of this study was to test the hypothesis that plasma T(3) concentration decreases with CR-induced reductions in fat mass but not in response to similar decreases in fat mass that are induced by exercise...

A bimetallic pillared-layer coordination framework {[Mn(3)(bipy)(3)(H(2)O)(4)][Cr(CN)(6)](2)·2(bipy)·4(H(2)O)}(n) has been constructed using a cyanometallate anion ([Cr(CN)(6)](3-)) and an organic linker (4,4'-bipyridyl) that provides high heat of hydrogen adsorption (∼11.5 kJ mol(-1)) and shows guest dependent magnetic modulation.
