If the hydrostatic pressure in the enteron of Hydra is made more than 2-4 mm of water greater than the outside pressure, the animal becomes distended, indicating that the normal enteron pressure is less than this. Positive enteron pressure attenuates the spontaneous, negative-going electrical spikes across the body wall, which are called contraction pulses (CP's) because of their relation to co...

PURPOSE To evaluate the effect of subclinical Helicobacter pylori infection on the gastric wall thickness with multislice computed tomography (MSCT). MATERIALS AND METHODS In 99 subjects without gastric disease, CT scans of the abdomen were obtained after water ingestion and intravenous contrast administration. CT images were evaluated for degree of luminal distention and the thickness of the...

Iontophoretic cobalt staining of the nematode Phocanema decipiens results in the deposition of cobalt between the contractile bases of adjacent muscle cells and in a hexagonal lattice pattern in the hypodermis. The possibility of staining sarcolemmal invaginations between muscle cells which are proprioceptive or coordinate the activity of adjacent muscle cells is suggested.

A 47 year old female with papillary thyroid carcinoma was referred to our department for post-treatment whole body iodine scanning. The acquired images revealed a focal zone of intense radiotracer uptake in the right lower quadrant of the abdomen. SPECT/CT fused slices showed a focal zone of the radioiodine (131I) uptake in the right colon wall. Colonoscopy revealed a pedunculated po...

The vertebrate body wall is regionalized into thoracic and lumbosacral/abdominal regions that differ in their morphology and developmental origin. The thoracic body wall has ribs and intercostal muscles, which develops from thoracic somites, whereas the abdominal wall has abdominal muscles, which develops from lumbosacral somites without ribs cage. To examine whether limb-genesis interferes wit...

A pair of large serotonergic neurons, the Retzius (Rz) cells, is found in each segment of the leech nervous system. Most Rz cells innervate the body wall of their own segment as well as adjacent anterior and posterior segments. Rz cells in segments 5 and 6 [Rz (5,6)] instead innervate the reproductive tissue found only in those segments. Rz cells from adjacent segments [Rz (4,7)] provide the se...

conclusions: finding the equivalent disease to htn based on iranian traditional medicine, could suggest a better strategy for preventing, treating and reducing debilitating its complications in the future. in conclusion, we can approach to hypertension with recommendations for reducing imtila when we are dealing with a kind of hypertension that corresponds to imtila. therefore, if patient is su...

Abstract Experimental and numerical investigations of a magnetic ponderomotive force acting on non-magnetic body immersed in ferrofluid were carried out. The study was performed nonmagnetic sphere cylindrical container filled with the fluid magnetized by uniform field. symmetry experimental setup allowed simplification problem: 2D axisymmetric simulation corresponded to 1D measurements. turned ...
