that given here, applies the term pyloric canal to the passage through the pyloric sphincter in X-ray photographs of the stomach (fig. 4) and in the description of the movements of the stomach. Most radiologists still use the terms pyloric antrum or pre-pyloric segment for what is anatomically the pyloric canal, though Shanks (1938) uses the terms pyloric canal and pylorus as synonymous, statin...

In several systems, including some well studied invertebrate "model" preparations, rapid, rhythmic inputs drive slow muscles. In this situation muscle contractions can summate temporally between motor neuron bursts, tonically contract, and low-pass filter broad-band input. We have investigated how the muscles innervated by each motor neuron type of the rapid, rhythmic (cycle period, approximate...

In the isolated stomatogastric nervous system of the lobster Fasus lalandii, the strong modifications of the pyloric motor pattern induced by firing of the single anterior pyloric modulator neurone (APM) are due primarily to modulation by APM activity of the regenerative membrane properties which are responsible for the 'burstiness' of all the pyloric neurones and particularly of the non-pacema...

PURPOSE The aim of this study was to evaluate the effect of simvastatin on the synthesis of cytokines TNF-α and IL-10 and metalloproteinase (MMPs) 2 and 9 in a rat model of ligature-induced periodontitis. MATERIALS AND METHODS Twenty Wistar rats were used, and a cotton ligature was place in a subgingival position encircling the entire cervix of the first molar of the left (ipsilateral) side o...

The hyperpolarization-activated inward cationic current (Ih) is known to regulate the rhythmicity, excitability, and synaptic transmission in heart cells and many types of neurons across a variety of species, including some pyloric and gastric mill neurons in the stomatogastric ganglion (STG) in Cancer borealis and Panulirus interruptus However, little is known about the role of Ih in regulatin...

In this work, we propose a 3D space handwriting recognition system by combining 2D space handwriting models and 3D space ligature models based on that the most different parts between 2D space handwriting characters and 3D space handwriting characters are the shapes of ligatures. We design the ligature model not dependent on each character but dependent on the incoming and the outgoing vector. ...

This in vivo experimental study evaluated the efficacy of fluoride-releasing elastomers in the control of Streptococcus mutans levels in the oral cavity. Forty orthodontic patients were recruited and divided into two groups of 20. Fluoride-releasing elastomeric ligature ties (Fluor-I-Ties, Ortho Arch Co. Inc., USA) were used in the experimental group, and conventional elastomeric ligature ties ...

OBJECTIVE We report a case of primary hypertrophic pyloric stenosis combined with a paraduodenal hernia in a 35-year-old woman. CLINICAL PRESENTATION AND INTERVENTION The patient presented with signs of obstructive ileus. CT of the abdomen revealed a marked dilatation of the stomach and the proximal jejunum as well as a circumferential thickening of the antral-pyloric region with characterist...

Generation of rhythmic pyloric motor output in the crustacean stomatogastric ganglion results from synaptic connections and cellular properties of a 14-cell network of pyloric neurons. These cellular properties are under the influences of modulatory inputs, which act, for the most part, in an activating mode, i.e., they enhance the bursting properties of the pyloric neurons and/or their ability...
