This study investigated the effects of angiotensin II "slow pressor" hypertension on structure and function of nerves supplying the renal vasculature. Low-dose angiotensin II (10 ng/kg per minute, initially sub-pressor) or saline vehicle was infused intravenously for 21 days in rats, and the effects were compared in renal and mesenteric arteries. Mean arterial pressure averaged 12+/-2 mm Hg hig...

Learning the associations between words and meanings is a fundamental human ability. Although the language network is cortically well defined, the role of the white matter pathways supporting novel word-to-meaning mappings remains unclear. Here, by using contextual and cross-situational word learning, we tested whether learning the meaning of a new word is related to the integrity of the langua...

Median arcuate ligament (MAL) syndrome, also known as the celiac axis compression syndrome (CACS) is rare, and a topic of ongoing academic controversy. CACS is a diagnosis of exclusion, characterized by the clinical triad of postprandial abdominal pain, weight loss, and vomiting. The classic management of CACS involves the surgical division of the MAL fibers. We report successful treatment of a...

In an excised cat kidney, the subcapsular veins were clipped near their connections with the renal vein and cut open distal to the clamps. The kidney was then placed in an oil-filled lucite chamber and perfused from a donor cat via tubes entering the chamber through its close-fitting lid. The blood leaking from the cut subcapsular veins was led to one flowmeter; that leaving via the cannulated ...

The internal anatomical structure of the above-ground vegetative organs S. nigrum  from Georgian flora - a rich source physiologically active compounds, has been examined using conventional laboratory methods used in microtechnics. study revealed diagnostic markers prospective medicinal plant. nigrum's aboveground are covered with conical, multicellular, hooked villis and rare spheroidal g...

Neurophysiological and anatomical data suggest the existence of several functionally distinct regions in lower arcuate sulcus adjacent postarcuate convexity macaque monkey. Ventral premotor F5c lies on consists a dorsal hand-related ventral mouth-related field. The posterior bank contains two additional F5 subfields at different anterior-posterior levels, F5a F5p. Anterior to F5a, area 44 has b...

The aim of this study was to investigate the origins and morphological features of the popliteus muscle in cadavers. In a sample of 40 lower limbs taken from cadavers the exact morphological features of the popliteus muscle were examined. In 100% of the cases studied we noticed, apart from the known femoral origin from the lateral femoral epicondyle, a fibular origin from the styloid process of...

The brain relies on a constant supply of glucose, its primary fuel, for optimal function. A taste-independent mechanism within the CNS that promotes glucose delivery to the brain has been postulated to maintain glucose homeostasis; however, evidence for such a mechanism is lacking. Here, we determined that glucokinase activity within the hypothalamic arcuate nucleus is involved in regulation of...
