The Arabidopsis SUC5 protein represents a classical sucrose/H(+) symporter. Functional analyses had revealed that SUC5 could also transport biotin, an essential cofactor for fatty acid synthesis. However, evidence for a dual role in the transport of the structurally unrelated compounds sucrose and biotin in plants was lacking. Here we show ...

Sex differences in stroke are observed across epidemiologic studies, pathophysiology, treatments, and outcomes. These sex differences have profound implications for effective prevention and treatment and are the focus of this review. Epidemiologic studies reveal a clear age-by-sex interaction in stroke prevalence, incidence, and mortality. While premenopausal women experience fewer strokes ...

Adenosine signaling is implicated in several neuropsychiatric disorders, including alcoholism. Among its diverse functions in the brain, adenosine regulates glutamate release and has an essential role in ethanol sensitivity and preference. However, the molecular mechanisms underlying adenosine-mediated glutamate signaling in neuroglial interaction remain elusive. We have previously shown that mice ...

Theoretically core-multishell nanowires under a cross-section of hexagonal geometry should exhibit peculiar confinement effects. Using a hard X-ray nanobeam, here we show experimental evidence for carrier localization phenomena at the hexagon corners by combining synchrotron excited optical luminescence with simultaneous X-ray fluorescence spectroscopy. Applied to single coaxial n-GaN/InGaN multiquantum-well/p-GaN nanowires, ...

Carbapenems are the most potent β-lactam antibiotics and key drugs for treating infections by Gram-negative bacteria. In such organisms, β-lactam resistance arises principally from β-lactamase production. Although carbapenems escape the activity of most β-lactamases, due in the class A enzymes to slow deacylation of the covalent acylenzyme intermediate, carbapenem-hydrolyzing class ...

Minimally invasive treatments of varicosis are increasingly establishing. Short and intermediate-term outcomes of endovenous treatments are satisfying: success rates are comparable with conventional surgery, whereas recovery is faster and complication rates are lower. Success rates are highest for endovenous laser ablation (EVLA). However, endovenous radiofrequency ablation (RFA) has advanced. Its ...

The standard formulation of tunneling transport rests on an open-boundary modeling. There, conserving approximations to nonequilibrium Green function or quantum statistical mechanics provide consistent but computational costly approaches; alternatively, the use of density-dependent ballistic-transport calculations (e.g., Lang 1995 Phys. Rev. B 52 5335), here denoted 'DBT', provides computationally efficient (approximate) atomistic ...

Skin responses to moderate and high doses of ionizing radiation include the induction of DNA repair, apoptosis and stress response pathways. Additionally, numerous studies indicate that radiation exposure leads to inflammatory responses in skin cells and tissue. However, the inflammatory response of skin tissue to low-dose radiation (≤10 cGy) is ...

ABSTRACT: Approximately 20 years has passed since the first human trial with HIV-1 protease inhibitors (PIs). PIs set the stage for combination therapy in the mid '90s but are now rarely used in first line combination therapy and reserved for salvage therapy. Initially, resistance to PIs was deemed unlikely due ...

Numerous methods are available for platelet-rich plasma (PRP) generation, but evidence defining the optimum composition is lacking. We hypothesized that leukocyte-reduced PRP would result in lower inflammatory cytokine expression compared with concentrated-leukocyte PRP and that maintaining the platelet:white blood cell (WBC) ratio would compensate for the effect of increased WBC ...
