Molecular mechanisms control the timing, sequence, and synchrony of developmental events in multicellular organisms. In Caenorhabditis elegans , these mechanisms are revealed through the analysis of mutants with "heterochronic" defects: cell division or differentiation patterns that occur in the correct line...
The breakdown of cell membranes by electrical and mechanical stress. We attempted to determine whether mechanical tension and electrical stress couple to cause membrane breakdown in cells. Using cell-attached patches from HE... J Akinlaja,F Sachs - 《Biophysical Journal》 被引量: 198发表: 1998...
For gene expression analysis, reactions were performed with three technical replicates of three biological rep- licates for each life stage. The relative normalized expression was calculated by 2−∆∆Cq method21 in con- trast with three validated reference genes expression (rpl18, rps17 and ...
sciences have led to a longer life expectancy and have increased the number of Alzheimer's disease patients. Ultimately, the prevention of disease before its occurrence is regarded to be one of the most important pillars of treatment at different stages of this disease. Treatment or postponement o...
Human gene expression first occurs between the four- and eight-cell stages of preimplantation development We describe here changes in the pattern of polypeptides synthesized during the pre-implantation stages of human development, and demonstrate that some of the... P Braude,V Bolton,S Moore - 《...
The other brand name is named after a famous fi lm star who has been actively promoting the edible oil as being a healthier option than other brands of oil. This type of oil has only been on the market for a short time. Seltec is fi nding it diffi cult to estimate the useful life...
Hepatic Dysfunction in Sickle Cell Disease: A New System of Classification Based on Global Assessment Background & Aims: Hepatic dysfunction in adults with sickle cell disease varies in character and severity from self-limited cholestasis to life-threat... Philip A. Berry and Timothy J.S. Cross...
aimed at evaluating the effects of five constant temperatures on the survival rate and the phenotypic plasticity of different traits, such as size (and other morphological parameters), developmental duration and energy value (yolk sac, body, and whole fish) of the early life stages of northern ...
a reference gene that must be expressed at stable levels regardless of experimental conditions, cell types, tissue, developmental stage or stress treatment13. Thus, it is necessary to validate the stability of the reference gene under determined experimental condition to ensure proper normalization and...
