Trehalose is a nonreducing disaccharide of glucose that functions as a compatible solute in the stabilization of biological structures under abiotic stress in bacteria, fungi, and invertebrates. With the notable exception of the desiccation-tolerant "resurrection plants," trehalose is not thought to accumulate to detectable levels in most plants. We report here the regulated overexpression of E...
Upon the incidence of DNA stress, the ataxia telangiectasia–mutated (ATM) and Rad3-related (ATR) signaling kinases activate a transient cell cycle arrest that allows cells to repair DNA before proceeding into mitosis. Although the ATM-ATR pathway is highly conserved over species, the mechanisms by which plant cells stop their cell cycle in response to the loss of genome integrity are unclear. W...
Budding yeast adjusts to increases in external osmolarity via a specific mitogen-activated protein kinase signal pathway, the high-osmolarity glycerol response (HOG) pathway. Studies with a functional Hog1-green fluorescent protein (GFP) fusion reveal that even under nonstress conditions the mitogen-activated protein kinase Hog1 cycles between cytoplasmic and nuclear compartments. The basal dis...

abstract the present study was an attempt to investigate the effect of critical thinking on writing ability of 60 iranian intermediate efl learners studying at chenar language institute in khuzestan, iran. to this end, the participants of the study were selected based on their performance in an pet test, a cornell critical thinking test form x and a pre-test of writing. the participants un...
در ایالات متحده حدود ۱۵ میلیون نفر آلوده به میکروب سل می باشند و هر سال ۳۰ هزار مورد جدید گزارش می شود. انتظار می رود تا سال ۲۰۰۰ این رقم به ۵۰۰۰۰ نفر در سال برسد. تست مانتو نسبت به تست چند سوزنی که قبلاً بسیار متداول بود، بمراتب دقیق تر است و بهمین دلیل به عنوان یک روش انتخابی برای غربالگری سل شناخته شده است. امروزه این تست اولین اقدام برای اثبات عفونت کلینیکی بوده و در صورتی که بطور دقیق ا...
the present research was conducted to explore the effect of employing two language teaching approaches, i.e. schema-based instruction (sbi) and translation-based instruction (tbi), on vocabulary knowledge, structure and reading comprehension ability of forty one female students learning english in grade one senior high school in rivash, kuhsorkh, iran. while sbi focuses on schemata, i.e. words ...
