this research was conducted to study the length-weight and length-length relationships and condition factor of six cyprinid fish species viz. alburnus atropatena , barbus lacerta , capoeta capoeta , carrasius gibelio , romanogobio macropterus and pseudorasbora parva from zarrineh river (urmia lake basin, iran). a total of 188 specimens ranging from 2.9 to 21.4cm in total length and 0.22 to 176g...

UNLABELLED This study was designed to assess the efficacy of gracilis muscle transposition in repairing recto-vaginal and rectourethral fistula. All patients had fecal diversion as a preliminary or concurrent step to fistula repair. Success was defined as healed fistula after stoma closure. RESULTS Six females and four males underwent gracilis muscle transposition from 1999 to 2006. Gracilis ...

We experimentally quantified predation rates between the native North Sea ctenophore Beroe gracilis and the introduced Mnemiopsis leidyi. A series of incubation experiments with varying M. leidyi prey concentrations (0.15 to 2.37 ind. l–1) and sizes (mean oral-aboral length: 5.9 to 20.6 mm) was conducted, and digestion rates were measured. B. gracilis fed readily on M. leidyi and reproduced on ...

The purpose of this study was to determine the relative magnitudes of the reflex effects mediated by cardiac receptors during anterior as opposed to inferoposterior ischemia of the left ventricle of the dog. Cessation of perfusion (coronary "occlusion") of the circumflex coronary artery (Cx) in 29 chloralose-anesthetized dogs with common carotids ligated (group I) resulted in significant bradyc...

BACKGROUND Press-fit fixation of patellar tendon-bone anterior cruciate ligament autografts is an interesting technique because no hardware is necessary. For hamstring tendon grafts, no biomechanical data exist of a press-fit procedure. HYPOTHESIS Press-fit femoral fixation of hamstring tendons is mechanically equivalent to press-fit patellar tendon-bone fixation. STUDY DESIGN Controlled la...

The photosynthetic protist Euglena gracilis contains chloroplasts surrounded by three membranes which arise from secondary endosymbiosis. The genes petA and petD, encoding cytochrome f and subunit IV of the cytochrome bf complex, normally present in chloroplast genomes, are lacking from the chloroplast DNA (cpDNA) of E. gracilis. The bf complex of E. gracilis was isolated, and the identities of...

The genus Decaphora Franganillo, 1931 is revised. Pseudosparianthis variabilis F.O. Pickard-Cambridge, 1900, Pseudosparianthis cubana Banks, 1909 and Thelcticopis pestai (Reimoser, 1939) are transferred to the genus; and P. cubana is considered a senior synonym of the type species, Decaphora trabiformis Franganillo, 1931. In addition, the female of T. pestai and the male of P. variabilis are de...

Euglena gracilis, a microalgal species of unicellular flagellate protists, has attracted much attention in both the industrial and academic sectors due to recent advances in the mass cultivation of E. gracilis that have enabled the cost-effective production of nutritional food and cosmetic commodities. In addition, it is known to produce paramylon (β-1,3-glucan in a crystalline form) as reserve...

HYPOTHESIS Treatment of fecal incontinence has been greatly improved by electrical stimulation of gracilis muscle transposed around the anal canal. Various configurations of the muscle have been used: single alpha, gamma, epsilon muscle loops, split sling, or double wrap. We report herein experimental data on muscle transformation and damage induced by the latter surgical approach. DESIGN, IN...
