background: the aim of this study was to evaluate over expression of epidermal growth factor receptor (egfr) gene in localized prostate cancers and determine its relation with clinical and pathological factors affecting the progression of the disease. methods: in the tissue samples of the patients with prostate cancer undergoing radical prostatectomy, egfr expression was evaluated by immunohist...

the effects of weight and length of barbus grypus broodstock on fingerlings reproductive characteristics and growth were investigated. we chose three female treatments  including weight and length groups (1) 2212.5±479g,  62.68±6.7cm, (2) 4518±780g,  79.12±4.36cm  and (3) 7712.5±1171g, 92.62±3.13cm. the same male broodstock were used for all the treatments with the weight and length size of 140...

Flagellar biogenesis in bacteria is a complex process in which the transcription of dozens of structural and regulatory genes is coordinated with the assembly of the flagellum. Although the overall process of flagellar biogenesis is conserved among bacteria, the mechanisms used to regulate flagellar gene expression vary greatly among different bacterial species. Many bacteria use the alternativ...

Knowing the nutrient status of growing media is a strategy for precision agriculture. The research aims to study Liberica coffee seedling response peat under influence bio-fertilizer. experiment used completely randomized design in factorial treatment arrangement with six replications. 1 st factor was types; fibric, hemic, and sapric 2 nd were inoculated non-inoculated by cellulolytic bacteria....

Defined media permitting extensive growth of representative pink radio-resistant tetracocci (Micrococcus radiodurans, Micrococcus roseus, and Micrococcus radiophilus) and two controls (an ultraviolet-sensitive mutant of M. radiodurans and Micrococcus luteus) are described. Availability of Fe (especially Fe3+) proved essential for good growth, as evidenced by (i) favorable effects of hydroxamic ...

Upadhyay, J. (Washington State University, Pullman) and J. L. Stokes. Anaerobic growth of psychrophilic bacteria. J. Bacteriol. 83:270-275. 1962.-Facultatively anaerobic psychrophilic bacteria are widely distributed in nature and can be readily isolated from a variety of foods, soil, sewage, and other habitats. Strictly anaerobic psychrophiles, however, could not be isolated. Temperature and ox...

Interactions between phytoplankton and heterotrophic bacteria have been intensively studied, but many aspects of these interactions are still unknown because most of the studies were performed under non-axenic conditions. Therefore, we investigated the growth and release of dissolved organic matter of the marine diatom Thalassiosira rotula in axenic culture in comparison to T. rotula cultures i...
