soils bacteria are frequently faced with various adverse environmental conditions and have developed a complex regulatory network to respond rapidly to environmental changes. in this study usefulness and applicability of stress proteins of bacteria which are produced after stress conditions were examined. the adaptation of soil bacteria involves the induction of stress proteins provide a nonspe...

the effects of drought and salinity stress on the growth and chemical compositions pennyroyal(mentha pulegium l.) plant were investigated. this experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (fc)) and five salt treatments with 0, 25, 50, 75 ...

drought stress, especially drought at terminal stages, plays an important role in reduction of yield in field crops such as common beans. 50 genotypes of common bean including 3 control genotypes (dehghan, bahman and naz) were used to evaluate and identify the tolerant genotypes. this experiment were performed in a randomized complete block design (rcbd) with three replications under two condit...

BACKGROUND We have previously shown that psychosocial stress induces acute changes in glucocorticoid (GC) sensitivity of pro-inflammatory cytokine production. However, hormones of the sympathetic adrenal medullary system complement endocrine regulation of inflammatory responses. The current study therefore aimed at investigating the effects of repeated acute stress exposure on catecholamine sen...

Adjoint methods of sensitivity analysis were applied to the California Current using the Regional Ocean Modeling Systems (ROMS) with medium resolution, aimed at diagnosing the circulation sensitivity to variations in surface forcing. The sensitivities of coastal variations in SST, eddy kinetic energy, and baroclinic instability of complex time-evolving flows were quantified. Each aspect of the ...

Repeated periods of maternal separation in the early life of rats decreased dopamine transporter expression and significantly increased dopamine responses to stress, and behavioral responses to either stress or cocaine. As adults, maternal separation animals showed increased sensitivity to the effects of cocaine on locomotor activity and greater sensitivity to stress-induced sensitization to th...

OBJECTIVE To better understand the ways in which adult attachment, sensory processing, and distress may be interrelated in healthy adults. METHOD A cross-sectional study design was used with a convenience sample of 116 healthy participants who completed questionnaires before participating in a cold pressor pain-inducement task. RESULTS Attachment anxiety was significantly positively correla...

For the first time an integrated piezoresistive microsensor, used for monitoring ball bonding, is rigorously simulated. The sensor is based on a CMOS n + -diffusion and located in situ below a standard bonding pad. It measures a value related to the ultrasound stress which is dissipated during ball bonding. We report on a 2D simulation tool based on the implementation of the governing equation ...
