OBJECTIVE Several hormones expressed in white adipose tissue influence food intake at the central level. We sought to determine whether resistin, a circulating adipose-derived hormone in rodents, has actions on the hypothalamus by determining the effects of central resistin injection on food intake and on hypothalamic Fos protein expression. DESIGN As resistin expression in adipose tissue is ...

Nonatherosclerotic vascular diseases of the mesenteric and renal arteries are considered to occur less frequently than those caused by occlusive atherosclerotic disease. However, when present, they pose a significant diagnostic and therapeutic challenge. Such disorders include fibromuscular dysplasia, median arcuate ligament syndrome, the renal nutcracker syndrome, and some forms of acute and c...

Median arcuate ligament syndrome is a rare cause of abdominal pain which results from compression of the celiac artery (CA) or rarely, the superior mesenteric artery by a ligament formed by the right and left crura of the diaphragm. We report a case of open surgical decompression of the CA by division of the median arcuate ligament for a 37-year-old female patient who had suffered from chronic ...

OBJECTIVE To investigate the effects of extraoperative electrical stimulation of fiber tracts connecting the language territories. METHODS We describe results of extraoperative electrical stimulation of stereotactic electrodes in 3 patients with epilepsy who underwent presurgical evaluation for epilepsy surgery. Contacts of these electrodes sampled, among other structures, the suprainsular wh...

The arcuate fasciculus (AF) connects cortical regions important in language processing, but how fiber coherence and organization relates to gray matter macrostructure remains uncharacterized. We used high-resolution structural and 30-direction diffusion imaging data from 36 healthy adults (24 male/12 female; mean age, 30.5 ± 9.8 years) to establish the relationships between AF microstructure an...

The neuronal circuits involved in the regulation of feeding behavior and energy expenditure are soft-wired, reflecting the relative activity of the postsynaptic neuronal system, including the anorexigenic proopiomelanocortin (POMC)-expressing cells of the arcuate nucleus. We analyzed the synaptic input organization of the melanocortin system in lean rats that were vulnerable (DIO) or resistant ...

The mechanical properties of the cochlear partition are fundamental to auditory transduction. We measured the point stiffness of the partition, in vivo, at up to 17 radial positions spanning its width, in the basal turn of the gerbil cochlea. We found the linear stiffness at the position that is most likely under the outer pillar cells to be 1.5 times greater than adjacent positions toward the ...

Chronic abdominal pain is one of the most frequent complaints of subjects visiting the gastroenterologist office and a large majority of these subjects have irritable bowel syndrome (IBS). Median arcuate ligament syndrome (MALS) is a rare cause of chronic abdominal pain that results from compression or ischemia of the celiac artery by the median arcuate ligament. Characteristic features include...

background: congenital uterine malformations are the result of disturbances in mullerian duct development. in patients with recurrent miscarriage, the reported frequency of uterine anomalies varies widely, from 1.8% to 37.6%. there are reports in which cervical cerclage has been shown to prevent preterm labor in uterine anomalies. the aim of this study was to compare the role of cervical cercla...
