it is now well established that the type la of serine/threonine protein phosphatases (pp1α) may be implicated in malignant phenotype. although the pp1α mrna level increased in livers at preneo-plastic stages of hepatocarinogenesis and all of examined rat ascites hepatomas, unexpectedly, dra-matically decreased in some of primary hepatomas. in order to elucidate the low level of pp1α mrna in som...

effect of zinc cyanide on protein and certain metabolites content and some enzymes activitieswas evaluated in liver, muscle and gill tissues of the freshwater fish, cirrhinus mrigala, during exposure andfollowing cessation of exposure. fish exhibited significant alterations in the biochemical parameters in alltissues studied. levels of total protein decreased in all tissues, where as free amino...

Context The development and survival of floodplain forests are dependent on the occurrence seasonal flooding that provides soil moisture nutrient availability suitable for microorganisms, which main sources enzymes involved in decomposition mineralisation organic matter. Aims We compared enzyme activities a forest Lower Vistula Valley, Poland, cut off 80 years from river by artificial embankmen...

Climate change models predict that future precipitation patterns will entail lower-frequency but larger rainfall events, increasing the duration of dry soil conditions. Resulting shifts in microbial C cycling activity could affect soil C storage. Further, microbial response to rainfall events may be constrained by the physiological or nutrient limitation stress of extended drought periods; thus...

introduction: application of edta may increase the heavy metal availability and phytoextraction efficiency in contaminated soils. in spite of that, it might also have some adverse effects on soil biological properties. metals as freeions are considered to be severely toxic, whereas the complexed form of these metalswith organic compounds or fe/mn oxides may be less available to soil microbes. h...

Alpha amylases have various applications in different industries. Immobilization of alpha -amylase produced by a strain of Bacillus sp isolated from soil of Dibrugarh District of Assam, India was studied. Partially purified enzyme with 4062.62U/ml activity was used for immobilization study. 4% Sodium alginate was used for immobilization of enzyme and the optimum temperature, pH and incubation p...
