Observers recognize subtle changes in the movements of others with relative ease. However, tracking a walking human is computationally difficult, because degree articulation high and scene can temporarily occlude parts moving figure. Here, we used functional magnetic resonance imaging to test hypothesis that superior temporal sulcus (STS) uses form cues aid biological movement tracking. The same 10 healthy subjects detected gait mannequin two experiments. In experiment 1, tested effects...

This study evaluated the effect of operative drainage main pancreatic duct (MPD) on functional derangements associated with chronic pancreatitis (CP).The author previously reported delayed impairment in an evaluation impact patients CP. The now reports a prospective 143 this diagnosis.Each patient underwent 1) ERCP, 2) Bentiromide PABA, 3) 72-hour fecal fat test, 4) oral glucose tolerance test (OGTT) and 5) meal (LIPOMUL)--stimulated polypeptide release (PP). All were stratified as...

When the Zollinger-Ellison syndrome was first identified, total gastrectomy proposed as most effective treatment for secretory manifestations of syndrome. Recently, however, great enthusiasm has developed medical by means Hi-receptor antagonists. The authors have cared 27 patients with at University Texas Medical Branch in past 12 years and been pleased results gastrectomy, which performed 23 (one patient refused operation three had lesser gastric operations). Twenty-three underwent...

Although it is generally assumed that release of cholecystokinin (CCK) the chief mechanism by which a fatty meal causes contraction gallbladder, measured CCK and gallbladder have never been correlated. We achieved this correlation in eight adult male volunteers, means specific radioimmunoassay for ultrasonographic imaging gallbladder. This study validates our correlates concentrations with changes size examination. Basal (82.6 ±10.4 pg/ml) rose significantly to maximum 411.1 ±79.9 pg/ml at...

The response of the anterior pituitary to surgical stress was studied in 13 patients undergoing a variety procedures (cholecystectomy,mastectomy,hemigastrectomy, femoral nailing). Radioimmunoassays serum thyroid stimulating hormone (TSH), luteinizing (LH), follicle (FSH) and growth (GH) were performed on samples obtained daily for 2 days prior operation (controls), at half-hour intervals during operation, 1,2,3,5 7 postoperatively. Cortisol (to reflect ACTH) measured patients. Growth...

Abstract Presently existing data on the properties of liquid metal-ammonia solutions are reviewed critically in relation to physical models and current theory. Emphasis is given inter-relation between electronic atomic structures solutions. The material organized according concentration regions characterized by differing ionic structures. In very dilute range, 0–10−3 mole per cent metal (MPM), behave as ideal electrolytes with solvated electrons positive ions species. Association these...

In a prospective study, 85 patients with chronic pancreatitis have been subjected to evaluation by morphologic analysis (endoscopic retrograde cholangiopancreatography), exocrine function tests (bentiromide PABA and 72-hour fecal fat testing), endocrine (oral glucose tolerance test fat-stimulated release of pancreatic polypeptide). All were graded on five-point system, 1 point assessed for an abnormal result in each the five performed. Zero score denoted mild disease; 1–2 points signaled...

The role of endogenously released cholecystokinin (CCK) in mediating gallblader (GB) contraction was evaluated 12 normal volunteers and 24 patients with gallstones (11 additional gallstone were excluded because failure adequate ultrasonographic visualization). CCK concentrations before after oral administration fat (Lipomul®) measured by a specific radioimmunoassay. release correlated changes GB volume determined simultaneously ultrasonography. On the basis gallbladder operative findings,...

Some tumors are responsive to hormone manipulation. gastric and colonic adenocarcinomas from both humans animals have specific gastrin receptors. A transplantable mouse colon adenocarcinoma cell line (MC-26) contains receptors; growth of MC-26 cancer in vivo is stimulated by pentagastrin (PG). The purpose this study was determine whether a gastrin-receptor antagonist, proglumide (PGL), would inhibit prolong survival tumor-bearing mice. Subcutaneous were induced injecting single-cell...

The detection of threat is a role that the amygdala plays well, evidenced by its increased response to fearful faces in human neuroimaging studies. A critical element face an increase eye white area (EWA), hypothesized be significant cue activating amygdala. However, another important social signal can EWA lateral shift gaze direction, which also serves orient attention potential threats. It unknown how differentiates between these increases and those are specifically associated with fear....

Recent experimental evidence suggests that the perception of temporal intervals is influenced by context in which they are presented. A longstanding example time-order-error, wherein two relative to one another order Here, we test whether an absolute judgment task preceding context. Human subjects participated a bisection with no anchor durations (partition method). Intervals were demarcated Gaussian blob (visual condition) or burst white noise (auditory persisted for seven logarithmically...
