during 2007 – 2008 different fruit gardens in shiraz (fars province, iran) were surveyed for samples being collected from infected apple, pear and quince trees. symptoms of the infected trees included water soaking of infected tissue, wilt and tissue necrosis, scorched and blackend of blossom bracts or young shoots. a total of 47 strains were isolated from infected trees using na medium. on the...

Generation time and S phase time of the jejunum in the normal golden hamster were estimated by the autoradiographic technic with thymidine-3H. These times were compared with the genera tion and S phase times of a group of hamsters with transplanted fibrosarcomas and a group with turpentine abscesses. The generation time was shorter in animals with necrotic lesions. It is suggested that the comm...

To investigate the effects of pioglitazone pretreatment on expression nuclear factor kappa B and intercellular adhesion molecule-1 p38 mitogen activated protein kinase pathway in pancreatic tissue rats with acute pancreatitis. 72 specific pathogen-free adult female Sprague–Dawley male were randomly divided into sham operation group, model group (pretreatment group), 24 each group. Compared amou...

Microextrusion-based bioprinting consists of extruding a cellularized hydrogel through nozzle known geometry. As consequence this travelling the nozzle, shear forces will inevitably be generated upon cells during extrusion process and have negative effect on cell viability, proliferation biological fate tissue. In present study for first time in field, flow simulation (lysis, necrosis, apoptosi...

Background: Current imaging-based discrimination between radiation necrosis versus recurrent glioblastoma contrast-enhancing lesions remains imprecise but is paramount for prognostic and therapeutic evaluation. We examined whether patients with exhibit distinct patterns of blood oxygenation-level dependent fMRI cerebrovascular reactivity (BOLD-CVR) as the first step to better distinguishing fro...

Coronary artery narrowing (CAN) induces tissue injury, which may involve myocyte necrosis and apoptosis. Insulin-like growth factor (IGF)-1 may counteract cell death, modifying the detrimental effects of myocardial ischemia. On this basis, CAN was produced in female FVB.Igf+/- mice and nontransgenic littermates, and the animals were euthanized 7 days later. CAN consisted of an 82% reduction in ...

Diabetic patients are at risk for spontaneous foot ulcers, chronic wounds, infections, and tissue necrosis. Current theories suggest that the development and progression of diabetic foot ulcers are mainly caused by arteriosclerosis and peripheral neuropathy. Tissue necrosis plays a primordial role in the progression of diabetic foot ulcers but the underlying mechanisms are poorly understood. Th...

We analyse necrosis growth due to thermal coagulation induced by laser light absorption and limited by heat diffusion into the surrounding live tissue. The tissue is assumed to contain a tumour in the undamaged tissue where the blood perfusion rate does not change during the action. By contrast, normal tissue responds strongly to an increase in the tissue temperature and the blood perfusion rat...

BACKGROUND/AIMS The objective of this study was to assess the prognostic roles of treatment response and tissue necrosis after chemoradiotherapy (CRT) in locally advanced rectal cancer. METHODS A total of 243 patients with locally advanced rectal cancer who underwent neoadjuvant CRT were included. Three treatment response groups were classified by their pathological stage results: complete tr...
