Sporadic colorectal cancer (CRC) characterized by high-level DNA microsatellite instability (MSI-H) has a favorable prognosis. The reason for this MSI-H survival advantage is not known. The aim of this study was to correlate proliferation, apoptosis, and prognosis in CRC stratified by MSI status. The proliferative index (PI) was measured by immunohistochemical staining with the Ki-67 antibody i...

Susceptibility to drought stress has restrained chickpea productivity at a global level, and the development of drought-tolerant varieties is essential maintain its productivity. Therefore, present study was conducted evaluate genetic divergence in selected genotypes their morpho-physiological responses under irrigated stressed conditions identify traits that account for better performance thes...

in order to locate the qtls involved in the inheritance of agronomical, physiological and metabolitical indicators of drought tolerance in barley, an experiment was carried out using a wheat-barley disomic addition lines. this research was conducted in 2003-2004 at the dry land agricultural research institute, sararood, kermanshah, iran. the results of analysis of variance revealed highly signi...

Leaf detachment is a common signal that triggers both the differentiation of dormant epiphyllous buds as well as the onset of foliar senescence in Kalanchoe pinnata Lam. (Pers.). The present study looked for any probable correlations among selected attributes of foliar senescence, e.g. soluble proteins, chlorophylls a and b (Chl(a+b)), and membrane stability index (MSI), and the antioxidative s...

The study assessed the individual and interactive role of acetylsalicylic acid (ASA) nitric oxide (NO) against excess copper (Cu) concentrations. Excess Cu significantly reduced growth photosynthesis, although application ASA NO mitigated reduction with much visible effect in their combination. oxidative effects have been evident as increased reactive oxygen species (ROS) production, resulting ...

introduction salinity has various effects on plant growth by affecting physiological processes. the decline in plant productivity under saline condition, frequently linked with the reduction of photosynthetic capability. it has been reported that efficiency of psii photochemistry (fv/fm) of numerous plant species have been decreased due to salt stress studies have shown that salicylic acid (sa...

this experiment was conducted to study the effect of plastic mulch on the growth and some physiological characteristics of two strawberry cultivars (paros and queen elisa) under drought stress. a factorial experiment was performed based on randomized complete block design with four treatments, including mulch, without mulch, normal irrigation (control) and deficit irrigation (-10 bar) with thre...

High-frequency microsatellite instability (MSI), defined as more than 20% unstable loci, is an inconsistent finding in hematologic malignancies; consequently, the significance of deficient DNA mismatch repair (MMR) to their pathogenesis has been questioned. To further investigate the relationship between MMR deficiency and genomic instability in hematologic malignancies, this study evaluated MS...
