BACKGROUND AND AIMS The role of per-oral pancreatoscopy (POP) in the evaluation of occult pancreatic duct (PD) lesions remains limited to case series. The aim of this study was to evaluate the ability of POP to differentiate malignant from benign diseases of the PD. METHODS Patients who underwent POP between 2000 and 2013 for the evaluation of indeterminate PD strictures, dilatations, or with...

The shape and polarity of the C. elegans gonad is defined during early gonadogenesis by two somatic gonadal precursor cells, Z1 and Z4, and their descendants. Z1 and Z4 divide asymmetrically to establish the proximal-distal axes of the gonad and to generate regulatory leader cells that control organ shape. In this paper, we report that pop-1, the C. elegans TCF/LEF-1 transcription factor, contr...

We describe experiments on the dynamics of pop-out from orientation. Target lines at an oblique orientation and orthogonal background elements were presented with various onset delays, and subjects' performance in target detection was measured. Detection rates increased for short delays compared to synchronous stimulus presentation, with a maximum at delta t = 30-60 ms. Control experiments show...

Portulaca oleracea L. has been used as a food and medicinal plant for thousands of years in China. Polysaccharides extracted from P. oleracea L. (POP) are its main bioactive compound and have multiple pharmacological activities. However, anti-fatigue effects of POP have not yet been tested. This study was designed to investigate the anti-fatigue effects of POP in mice using the rotarod and forc...

Nine new Chinese species of Cephennodes are described: C. (s. str.) intricatus sp. n. (Gansu), C. (s. str.) cryptointricatus sp. n. (Gansu), C. (s. str.) monofoveatus sp. n. (Shaanxi), C. (s. str.) pinnapes sp. n. (Sichuan), C. (s. str.) elegantissimus sp. n. (Sichuan), C. (s. str.) palpalis sp. n. (Gansu), C. (Fusionodes) corpulentus sp. n. (Sichuan), C. (Fusionodes) gutta sp. n. (Shaanxi) and...

INTRODUCTION Gastroparesis, or delayed gastric emptying, can be diagnosed with gastric emptying scintigraphy. Manometric studies of patients with gastroparesis show increased pyloric tone (pylorospasm). Among the recent endoscopic therapies for pylorospasm is peroral endoscopic pylorotomy (POP). In this study, we explored the effect of POP on gastric emptying in healthy pigs. MATERIAL AND MET...

background and objective: cervical cancer involves many women annually and pop smear test has played a significant role in reducing its mortality and for this reason, its improvement is very essential. in this respect, cervex brush is a new tool that has been introduced in many countries. therefore, this study was conducted to compare pop smears from cotton swab-spatula and cervex brush methods...

BACKGROUND The efficacies of adjuvant stereotactic radiosurgery (SRS) and external beam radiation therapy (EBRT) for atypical meningiomas (AMs) after subtotal resection (STR) remain unclear. OBJECTIVE To analyze the clinical, histopathological, and radiographic features associated with progression in AM patients after STR. METHODS Fifty-nine primary AMs after STR were examined for predictor...

Penicillin production by free and agar immobilized Penicillium chrysogenum cells was investigated in a stirred tank reactor. increased two times with cells. In order to verify the oxygen transfer efficiency STR, mass coefficient determined using dynamic gassing out method at end of steady state operation reactor after achieving penicillin production. The (KLa) obtained STR 20% (V/V) beads, 1 VV...

objective(s): short tandem repeat (str) loci are the most informative dna genetic markers for attempting to individualize biological material for application in paternity and forensic cases. materials and methods: blood samples were collected and the total genomic dna was extracted. the dna samples were used for genotyping vwa and tpox str loci using pcr and polyacrylamide gel electrophoresis. ...
