Exposure to long-term stress has a variety of consequences on the brain and cognition. Few studies have examined the influence of long-term stress on event related potential (ERP) indices of error processing. The current study investigated how long-term academic stress modulates the error related negativity (Ne or ERN) and the error positivity (Pe) components of error processing. Forty-one male...
Drought stress is one of the main environmental factors that affects growth and productivity of crop plants, including lentil. In the course of evolution evolution, crucial genetic regulations mediated by non-coding RNAs (ncRNAs) have emerged in plant in response to drought and other abiotic stresses. In the present study, after identifying lncRNAs within the expression profile of lentil, RNA-s...
Depression risk is exacerbated by genetic factors and stress exposure; however, the biological mechanisms through which these factors interact to confer depression risk are poorly understood. One putative biological mechanism implicates variability in the ability of cortisol, released in response to stress, to trigger a cascade of adaptive genomic and non-genomic processes through glucocorticoi...
Bisphosphonates are potent inhibitors of bone resorption and widely used to treat osteoporosis. Extensive studies have shown that therapy with bisphosphonates improves bone density and decreases fracture risk. However, concerns have been raised about potential over-suppression of bone turnover during long-term use of bisphosphonates, resulting in increased susceptibility to and delayed healing ...
The identification of critical components in plant salt stress adaptation has greatly benefitted, in the last two decades, from fundamental discoveries in Arabidopsis and close model systems. Nevertheless, this approach has also highlighted a non-complete overlap between stress tolerance mechanisms in Arabidopsis and agricultural crops. Within a long-running research program aimed at identifyin...
Heavy physical work can result in physiological stress and suppressed immune function. Accordingly, long-distance migrant birds that fly for thousands of km within days can be expected to show immunosuppression, and hence be more vulnerable to infections en route. The red knot Calidris canutus Linnaeus is a long-distance migrant shorebird. We flew red knots the equivalent of 1500 km over 6 days...
The mechanism of AgCl-induced stress corrosion cracking Ti-6246 was examined at 500 MPa and 380 °C for 24 h exposures. SEM STEM-EDX examination a FIB-sectioned blister crack showed that metallic Ag formed migrated along the crack. TEM analysis also revealed presence SnO2 Al2O3 products mixed into TiO2. fracture surface has transgranular nature with brittle appearance in primary α phase. Long, s...
in this study, accumulation of h2o2, malondialdehyde (mda) (as cold-induced oxidative stress indicators), the transcript levels of dehydrin and beta-glucosidase genes (involved in metabolic responses) was evaluated in chickpea cv. jam, using qrt-pcr during control, cold acclimation (ca), cold stress (cs), recovery, and freezing phases. results showed the existence of wide range of genetic capac...
objective(s): crocin influences many biological functions including memory and learning. the present study was aimed to investigate the effects of crocin on learning and memory impairments in streptozotocine-induced diabetic rats. materials and methods: diabetes was induced by intraperitoneal (ip) injection of streptozotocin (stz, 45 mg/kg). transfer latency (tl) paradigm in elevated plus-maze ...
mycophenolate mofetil (mmf) as an immunosuppressive agent is used to prevent graft rejection. one of the adverse effects of long time administration of mmf is the gastrointestinal disorder. this study aimed to investigate the gastroprotective effect of silymarin (smn) on mmf-induced gastrointestinal (gi) disorders. twenty-four adult female wistar rats were assigned into three groups including t...
