Density functional theory was employed to study the influence of O-phosphorylation of serine, threonine, and tyrosine on the amidic (15)N chemical shielding anisotropy (CSA) tensor in the context of the complex chemical environments of protein structures. Our results indicate that the amidic (15)N CSA tensor has sensitive responses to the ...

We study the transmission properties of a one-dimensional array with intersite side-coupled defect and demonstrate that, as the system undergoes sharp Fano resonance, it exhibits geometry-induced vorticity of the energy flux. The optical vortex inverts its handedness at the Fano resonance, revealing a strong link between two phenomena, both being ...

Climate change and variability are affecting human health and disease direct or indirectly through many mechanisms. Dengue is one of those diseases that is strongly influenced by climate variability; however its study in Central America has been poorly approached. In this study, we assessed potential associations between macroclimatic and microclimatic ...

BACKGROUND: Hemorrhage caused by inflammatory vessel erosion represents a life-threatening complication after upper abdominal surgery such as pancreatic head resection. The gold standard therapeutic choice is an endovascular minimally invasive technique such as embolization or stent placement. Hepatic arterial hemorrhage in presence of pancreatitis and peritonitis is a particular challenge ...

CONTEXT: Anorexia nervosa (AN) is an eating disorder, resulting in sustained low weight and marked decrease in fat mass. Interleukin 6 (IL-6) may play a role in appetite, energy expenditure and body weight control. IL-6 acts through binding with membrane receptor (IL-6R) and activates glycoprotein 130 (gp130) signaling. Both IL-6R ...

Regardless of the mode of treatment, clubfoot has a strong tendency to relapse, especially hindfoot equinus. Because contraction or shortening of the Achilles tendon causes an equinus deformity of the ankle, release of this tendon is required to correct equinus deformity in patients with residual or relapsed clubfoot. This study ...

We report a continuous-wave, broadly tunable mid-infrared MgO:PPLN optical parametric oscillator pumped by a fiber amplifier. Using pump tuning with synchronized temperature optimization, we achieve the broadest mode-hop-free (MHF) tuning of idler light over 30  cm<sup>-1</sup>. We further use this tunable mid-infrared laser to demonstrate high-resolution absorption spectroscopy of methane across ...

Enterotoxigenic Escherichia coli F18 is a major pathogen that causes postweaning diarrhoea and edema disease in piglets. The alpha(1,2)-fucosyltransferase (FUT1) gene has been identified as an ideal candidate gene for controlling the expression of the receptor for ECF18 bacteria. Therefore, the use of RNA interference (RNAi) to study the function ...

A semianalytical Fabry-Perot model is presented to investigate the electromagnetic enhancement by double grooves in gold substrate. The influence of hybrid wave (HW) propagating along the metal surface on field enhancement is explored systematically with a HW model. Simulation results imply that the hybrid generated by one groove can affect ...

High-resolution infrared absorption spectroscopy of acetylene gas is demonstrated in a dispersion-engineered photonic crystal waveguide under slow-light propagation. Experimental enhancement factors of 0.31 and 1.00 are obtained for TE and TM polarization, respectively, for group indices ranging from 1.5 to 6.7. The dependence of molecular absorption on the evanescent electric-field ...

True left ventricular aneurysms are thought to arise from the expansion and thinning of the transmural infarct area, whereas false aneurysms result from containment of ventricular rupture by pericardial adhesions. We reported a case of true left ventricular aneurysm with pseudoaneurysm( mixed type aneurysm) which was treated surgically.
