Patients presenting with acute coronary syndromes (ACS) remain amongst the highest-risk of all acute medical admissions. Despite significant reductions in morbidity and mortality via refinements in treatment methods in recent years, such individuals remain at a high risk of recurrent ischaemic events and death. Whilst 2012 has brought a wealth ...

An unusual α-(1,1)-galacturonic acid (GalA) lipid A modification has been reported in the lipopolysaccharide (LPS) of a number of interesting Gram-negative bacteria including the nitrogen fixing bacteria Azospirillum lipoferum, Mesorhizobium huakui and M. loti, the stalk forming bacterium Caulobacter crescentus, and the hyperthermophillic bacterium Aquifex aeolicus. However, the α-(1,1)-GalA transferase ...

Sensory neurons with afferent axons from the kidney are extraordinary in their response to electrical stimulation. More than 50% exhibit a tonic firing pattern i.e. sustained action potential firing throughout depolarizing, pointing to an increased excitability, whereas non-renal neurons show mainly a phasic response, i.e. <5 action potentials. Here we ...

Remembering to perform deferred actions when an event is encountered in the future is referred to as event-based prospective memory (PM). We examined whether the failure of individuals to allocate sufficient attentional resources to nonfocal PM tasks can be linked to the response demands inherent in PM paradigms that require ...

Muscle force production and power output in active males, regardless of the site of measurement (hand, leg, or back), are higher in the evening than in the morning. This diurnal variation is attributed to motivational, peripheral and central factors, and higher core and, possibly, muscle temperatures in the evening. This ...

The nature of electronically excited states of the super-reduced form of vitamin B12 (i.e., cob(I)alamin or B12s) a ubiquitous B12 intermediate, was investigated by performing quantum-chemical calculations within the time-dependent density functional theory (TD-DFT) framework and by establishing their correspondence to experimental data. Using response theory, the electronic absorption (Abs), ...

Insulin secretion is coupled to changes in ß-cell metabolism. To define this process, 195 putative metabolites, mitochondrial respiration, NADP+, NADPH, and insulin secretion were measured within 15 minutes after stimulation of clonal INS-1 832/13 ß-cells with glucose. Rapid responses in the major metabolic pathways of glucose occurred, involving several previously ...

Current data suggest that advances in cardiovascular (CV) treatment have resulted in significant reduction in CV mortality but also in prolongation of life with disability. Focus on CV prevention is likely to reverse this unfavourable trend. In this review we provide information on the new European guidelines on CV prevention ...

The development of rational and effective engineered bioremediation approaches for sites contaminated with chlorinated solvents requires a fundamental understanding of the factors limiting the in situ activity of dehalorespiring bacteria. Frequently, multiple dehalorespiring bacteria are present at contaminated sites, particularly when bioaugmentation is applied. The ecological interactions between different dehalorespiring ...

The evidence in favor of early surgical treatment of anterior cruciate ligament (ACL) injuries in children is increasing. However, the controversy regarding the safety of such a procedure in young athletes with wide open physes remains unresolved. We reviewed prospectively collected outcome data on consecutive patients who had undergone transphyseal ...

A qualitative and quantitative determination method for chloropropanols in soy sauce was developed by GC-MS/MS with coupled column separation without derivatisation. The target compounds were 1,3-dichloropropan-2-ol (1,3-DCP), 2,3-dichloropropan-1-ol (2,3-DCP), 3-monochloropropane-1,2-diol (3-MCPD) and 2-monochloropropane-1,3-diol (2-MCPD). 3-MCPD-d(5) was used as an isotope internal standard for MCPDs and 1,3-DCP-d(5) for DCPs. After spiking ...

We have previously demonstrated effects of aldosterone on cell growth and on contractility in vascular smooth muscle cells. We showed these effects could occur via the classic mineralocorticoid receptor (MR) as well the G protein coupled estrogen receptor (GPER). However, the mechanisms underlying aldosterone's endothelial-dependent actions are unknown. Further, the ...

The nature of culture-specific startles syndromes such as "Latah" in Indonesia and Malaysia is ill understood. Hypotheses concerning their origin include sociocultural behavior, psychiatric disorders, and neurological syndromes. The various disorders show striking similarities despite occurring in diverse cultural settings and genetically distant populations. They are characterized clinically by exaggerated ...

The neurophysiological correlates of dreaming remain unclear. According to the "arousal-retrieval" model, dream encoding depends on intrasleep wakefulness. Consistent with this model, subjects with high and low dream recall frequency (DRF) report differences in intrasleep awakenings. This suggests a possible neurophysiological trait difference between the 2 groups. To test this ...

Endogenous circadian clocks are synchronized to the 24-h day by external zeitgebers such as daily light and temperature cycles. Bumblebee foragers show diurnal rhythms under daily light:dark cycles and short-period free-running circadian rhythms in constant light conditions in the laboratory. In contrast, during the continuous light conditions of the arctic ...

BACKGROUND: Assays of antigen expression on myeloid cells have an underlying premise that the assay integrates high purity gating of the leukocyte subpopulation in question. While CD45/side scatter (SSC) gating provides sufficient gating purity for qualitative assays of antigen expression; it is unsuitable for quantitative assays of antigen changes, especially ...

Over and over again: Various alkenes underwent the title reaction in the presence of rhodium/bis(diazaphospholane) complexes to give γ-chiral α,β-unsaturated carbonyl products (46-96 % yield) with high enantioselectivity (90-99 % ee). Iterative sequences of the reaction lead to stereoselective CC bond formations between achiral reactants to produce product having multiple stereocenters (see ...
