Lithium, generally, occurs in barely trace amounts in ground water with few major exceptions. One of these is the northern area of Chile where all potable water and many of the food stuffs contain high levels of lithium. Surface water can contain between 100 and 10,000 times more than most ...

The potential atheroprotective effects of glucagon-like peptide-1 (GLP-1), long-acting GLP-1 analogues and inhibitors of the enzyme dipeptidyl peptidase 4 (DPP-4) are currently the subject of intense research. Recent evidence suggests the effects of DPP-IV inhibitors, may, in-part, be mediated by GLP-1 independent molecular mechanisms. In this report we demonstrate that ...

Microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), and eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome) are conditions classified under the general heading of antinuclear cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV). Lung lesion is a very common and important clinical feature in AAV. In MPA, diffuse alveolar hemorrhage and pulmonary fibrosis (PF) are ...

We investigated the physiological mechanism of grapheme-color synesthesia using metacontrast masking. A metacontrast target is rendered invisible by a mask that is delayed by about 60 ms; the target and mask do not overlap in space or time. Little masking occurs, however, if the target and mask are simultaneous. This effect ...

Radionuclide cardiac imaging has potential to assess underlying molecular, electrophysiologic, and pathophysiologic processes of cardiac disease. An area of current interest is cardiac autonomic innervation imaging with a radiotracer such as (123)I-meta-iodobenzylguanidine ((123)I-mIBG), a norepinephrine analogue. Cardiac (123)I-mIBG uptake can be assessed by planar and SPECT techniques, involving determination of ...

In Western populations, male gender atypicality (i.e., cross-gender behavior and identity) and male androphilia (i.e., sexual attraction to adult males) tend to cluster in particular families. Here, we examined whether this familial clustering effect extended to non-Western populations by examining the genealogical relationships of 17 Samoan transgendered androphilic males, known ...

Franz Schneider (13.09.1812-29.11.1897) in 1850 was appointed the first lecturer on "Chemistry for physicians" by the Viennese university. Two years later he accepted the professorship in the military medical schools in the "Josephinum" from where he shifted to the philosophical faculty as professor of "Common and medical chemistry". Soon after ...

The antiapoptotic factor Livin has been considered critical for tumor progression and poor prognosis for variant types of tumors. However, there are only limited reports regarding its expression and biological functions in colon cancer. Here, we examined Livin expression in four colon cancer cell lines (HCT116, RKO, KM12C, and SW620) ...

This article describes the relevance of a culturally grounded approach toward drug prevention development for indigenous youth populations. This approach builds drug prevention from the "ground up" (i.e., from the values, beliefs, and worldviews of the youth that are the intended consumers of the program) and is contrasted with efforts ...

Past fMRI research has demonstrated that to understand other people's behavior shown visually, the mirror network is strongly involved. However, the mentalizing network is also recruited when a visually presented action is unusual and/or when perceivers think explicitly about the intention. To further explore the conditions that trigger mentalizing activity, ...

Modern semiempirical methods are of sufficient accuracy when used in the modeling of molecules of the same type as used as reference data in the parameterization. Outside that subset, however, there is an abundance of evidence that these methods are of very limited utility. In an attempt to expand the ...

Mass spectrometry (MS)-based phosphoproteomics has achieved extraordinary successes in qualitative and quantitative analysis of cellular protein phosphorylation. Considering that an estimated level of phosphorylation in a cell is placed at well above 100,000 sites, there is still much room for improvement. Here, we attempt to extend the depth of phosphoproteome ...

Many plant species excrete organic acids into the rhizosphere in response to aluminum stress to protect sensitive cells from aluminum rhizotoxicity. When the roots of Eucalyptus camaldulensis, a major source of pulp production, were incubated in aluminum-toxic medium, citrate released into the solution increased as a function of time. Citrate ...

Single-stage nitritation-anammox combines the growth of aerobic ammonium-oxidizing bacteria (AOB) and anaerobic ammonium oxidizing bacteria (AnAOB) in one reactor. The necessary compromise of their milieu conditions often leads to the growth of nitrite-oxidizing bacteria (NOB). For this study, a sequencing batch reactor (SBR) for nitritation-anammox was operated for 180 days with ...

Bone fracture risk can increase through bone microstructural changes observed in bone pathologies, such as glucocorticoid-induced osteoporosis. Resorption cavities present one of these microstructural aspects. We recently found that glucocorticoids (GCs) affect the shape of the resorption cavities. Specifically, we found that in the presence of GC osteoclasts (OCs) cultured ...

The circadian clock machinery is responsible for biological timekeeping on a systemic level. The central clock system controls peripheral clocks through a number of output cues that synchronize the system as a whole. There is growing evidence that changing cellular metabolic states have important effects on circadian rhythms and can ...

Hydrophobic interactions constitute one of the most important types of non-specific interactions in biological systems, which emerge when water molecules rearrange as two hydrophobic species come close to each other. Prediction of hydrophobic interactions at the level of nanoparticles (Brownian objects) remains challenging, because of uncontrolled diffusive motion of the ...

Summary The POU family subclass V (POU-V) proteins have important roles in maintaining cells in an undifferentiated state. In Xenopus, expression of the POU-V protein Oct60 was detected in oocytes and was found to decrease in blastula- to gastrula-stage embryos. In addition, Oct60 overexpression inhibits some signals in early embryogenesis, ...

Solvent composition has a large influence on measured antioxidant potential (AOP) of model polyphenols and red wines with 2,2-diphenyl-1-picrylhydrazyl (DPPH). We have shown that incorporation of aqueous buffer in the assay medium results in higher reactivity of catechin and caftaric acid, that are among major polyphenolic constituents of wines. Consequently ...

Vascular dysfunction is the underlying cause of nearly 80% of heart disease cases, and its initiation and progression can be exacerbated by circulating factors, such as insulin-like growth factor-1 (IGF-1). IGF-1, which is highly homologous to insulin, elicits a response via a classical tyrosine kinase receptor, the IGF-1R. However, it ...
