Tracking the presence, distribution and disappearance of biological soil crusts is important for ecosystem management of desert regions and provides highly valuable information on desertification and climate change studies in arid environments. Based on the analysis of the spectral features of biological soil crusts, we propose a new biological soil crust index (BSCI) for biological soil crusts...

many biological factors affect radiosensitivity. in this study, radiosensitivity among the different blood groups was investigated. peripheral blood sample of 95 healthy people were divided into two parts. one part was irradiated with 2 gy co-60 gamma rays and the second one was considered as control. then all the samples were studied by cytokinesis-blocked micronucleus assay (cbmn assay). our ...

Cell suspensions of tumor or normal bone marrow were incubated in vitro with control media (supplemented Ham's F-10 medium or autologous, pretreatment plasma) and with autologous, posttreatment plasma containing chemotherapeutic agents or their metabolites (treated plasma). Drug-specific perturbation of tumor cell DNA synthesis, as measured by the thymidine labeling index, occurred in treated p...

AIM To analyse the correlation between (18)F-FDG uptake assessed by PET/CT in locally advanced breast tumours and histopathological and immunohistochemical prognostic factors. MATERIAL AND METHODS Thirty-six women with breast cancer were prospectively evaluated. PET/CT was requested in the initial staging previous to adjuvant chemotherapy (multicentric study). All the patients underwent an (1...

an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...

Schizophrenia patients have impairments at several levels of cognition including visual attention (eye movements), perception, and social cognition. However, it remains unclear how lower-level cognitive deficits influence higher-level cognition. To elucidate the hierarchical path linking deficient cognitions, we focused on biological motion perception, which is involved in both the early stage ...
