The study of the congenitally blind (CB) represents a unique opportunity to explore experience-dependant plasticity in a sensory region deprived of its natural inputs since birth. Although several studies have shown occipital regions of CB to be involved in nonvisual processing, whether the functional organization of the visual cortex observed in sighted individuals (SI) is maintained in the re...

We quantify the innate electro-oxidation behavior of a single Ti3C2Tx MXene particle by Single-Entity Electrochemistry. undergoes irreversible oxidation at potentials greater than 0.3 V (vs. SCE), with extent dependant on applied potential. A close correlation is seen ensembles drop-cast particles submonolayer coverage.

UNLABELLED Gated SPECT recorded with 16 intervals determines left ventricular (LV) ejection fraction more accurately than does gated SPECT recorded with 8 intervals but produces higher image noise. This study aimed to assess the results from sestamibi and (201)Tl 16-interval gated SPECT when both signal-to-noise ratio and spatial resolution were enhanced with an original method of reconstructio...

PURPOSE In gram-negative bacteria, active efflux pumps that excrete drugs can confer resistance to antibiotics however, in Helicobacter pylori this role is not well established. The purpose of this study is to evaluate the role of active efflux in resistance of H. pylori isolates to antibiotics. MATERIALS AND METHODS Twelve multiple antibiotic resistant (MAR) isolates resistant to at least fo...

We examined the ability of cardiac endothelial nitric oxide synthase (eNOS) to couple myocardial oxygen consumption (MVo(2)) and oxygen delivery during pregnancy. Awake dogs were studied using echocardiography before and at 40 days, 50 days, and 60 days (60D) of pregnancy and at approximately 14 days postpartum. Left ventricular eNOS, phosphorylated eNOS, and copper, zinc-superoxide dismutase (...

objective(s): the adverse effects of pyridaben on reproductive system in male animals are not well established. this study was designed to elucidate how pyridaben can effects the histomorphometric, hormonal alternations and reproductive functions of balb/c mice .   materials and methods : for this study, 80 adult and apparently healthy male balb/c mice were divided into three groups viz, contro...

in shallow foundations, the third bearing capacity factor, n, has been found to show a decreasing tendency with increasing the foundation size. it is supported by experimental observations and related mainly to stress level dependent nature of the soil. on the other hand, the bearing capacity is often obtained theoretically without consideration of the foundation vertical displacements. in thi...
