OBJECTIVE Violence, accidents and natural disasters are known to cause post-traumatic stress, which is typically accompanied by fear, suffering and impaired quality of life. Similar to chronic diseases, such events preoccupy the patient over longer periods. We hypothesised that post-traumatic stress could also be caused by Crohn's disease (CD), and that CD specific post-traumatic stress could b...

Plant-associated bacteria are of great interest because of their potential use in phytoremediation. However, their ability to survive and promote plant growth in metal-polluted soils remains unclear. In this study, a soilborne Cd-resistant bacterium was isolated and identified as Enterobacter sp. strain EG16. It tolerates high external Cd concentrations (Cd(2+) MIC, >250 mg liter(-1)) and is ab...

Cadmium (Cd) is a non-essential heavy metal that is toxic to plants. microRNAs (miRNAs) are 21-nucleotide RNAs that are ubiquitous regulators of gene expression at the post-transcriptional level. Several plant miRNAs, such as miR390, have vital roles in plant growth, development and responses to environmental stresses including heavy metal stress. In this study, the expression of mature miR390 ...

Naturally plants exposed with many adverse environmental conditions like biotic and a biotic stress. Despite all others stresses heavy metal stress is one of great importance which has a notable adverse effects on crop productivity and growth, heavy metal stress triggers different responses in plants, ranging from biochemical responses to crop yield. Understanding the biochemical and molecular ...

Autophagy is protective in cadmium (Cd)-induced oxidative damage. Endoplasmic reticulum (ER) stress has been shown to induce autophagy in a process requiring the unfolded protein response signalling pathways. Cd treatment significantly increased senescence in neuronal cells, which was aggravated by 3-MA or silencing of Atg5 and abolished by rapamycin. Cd increased expression of ER stress regula...

Cadmium (Cd) brings a devastating health hazard to human being as a serious consequence of agricultural and environmental contamination. We demonstrated the protective effect of silicon (Si) on cadmium (Cd)-stressed rapeseed (Brassica napus L. cv. BINA Sharisha 3) plants through regulation of antioxidant defense and glyoxalase systems. Twelve-day-old seedlings were exposed to Cd stress (0.5 and...

Cadmium (Cd) is one heavy metal which is toxic and can cause physiological disorder of plants. In the present experiment, effects of Sodium nitroprusside (SNP), a NO donor, on the phenotype, photosynthesis and oxidative stress of cucumber leaves were studied under Cd stress. Application of 100μM CdCl2 induced obvious chlorosis of cucumber leaves with lower pigment content and lower net photosyn...

This study examined whether conduct disorder (CD) was associated with war zone stress and war-related post-traumatic stress disorder (PTSD) symptoms in American Indian (AI) Vietnam veterans. Cross-sectional lay-interview data was analyzed for 591 male participants from the American Indian Vietnam Veterans Project. Logistic regression evaluated the association of CD with odds of high war zone st...

Reported findings on cortisol reactivity to stress in young people with ADHD are very variable. This inconsistency may be explained by high rates of comorbidity with Conduct Disorder (CD). The present study examined cortisol responses to a psychosocial stressor in a large sample of adolescent males with ADHD (n=202), with or without a comorbid diagnosis of Conduct Disorder (CD). Associations be...

The tumor suppressor oncoprotein, p53, is a critical regulator of stress-induced growth arrest and apoptosis. p53 activity is regulated through the ubiquitin proteasome system (UPS) with stress-induced disruption leading to increased accumulation of p53, resulting in growth arrest. In the present study, we investigate the role of p53 to determine sensitivity to cadmium (Cd) and whether inductio...
