Observed differences could be due to residual effects of cannabis, reluctance to endorse negative mood states, or to issues related to identifying (i.e., emotional identification) or feeling (i.e., interoception) stress-related affective states. Conclusion: These results indicate that CANs have blunted mood responses to social stress, but normative physiological stress responding. CANs had blunted subjective response to stress relative to CONs, but they did not differ in physiological (cortisol and cardiovascular) stress responding. Overall, the TSST produced expected increases in anxiety, negative mood states, cortisol, and heart rate. Eight CANs and one CON smoked tobacco cigarettes daily. CANs smoked cannabis 6.4 ± 1.1 days/week. Results: Nineteen CANs (1 female) and 20 CONs (2 female) participated groups were matched on trauma exposure, sex, race, and age. Outcome measures were subjective mood, heart rate, and salivary cortisol. Methods: Healthy, non-treatment-seeking adult CANs (⩾4×/week smoking cannabis as usual) and demographically matched CONs completed the TSST. We assessed responses to a standardized laboratory social stress assay (the Trier Social Stress Task TSST) in regular cannabis smokers (CANs) compared with controls (CONs). Little prior research has focused on stress responses in regular cannabis smokers. Physiology of hydroponically grown plants requires more research work as it is an alternative technology to grow plants in lands where soils are non fertile or where space or agriculture is a constrain.īackground: Aspects of the canonical stress response differ in stimulant, opioid, and alcohol users relative to controls, and dysregulated responses to stress may contribute to continued use of these drugs. Total Sugar and protein content in soil grown okara & moong seedlings were slightly higher in comparison to those grown hydroponically indicating that soil is best medium for plant growth. Chlorophyll content was found to be higher in okra and moong plants grown in soilless culture. A slight variation in relative water content (RWC) was observed. Our results showed higher root ratio in plants grown in hydroponics than in the soil. The present work was planned with an objective to undertake physiological and biochemical studies such as relative water content (RWC), root shoot ratio, chlorophyll content, sugars and protein in vegetable plants (pea, okra and moong) grown with soil and soil-less cultures (hydroponics). Although hydroponic is now being practiced with total success, not many studies are done on the physiology and biochemistry of the plant grown. It requires less space, adds greenery around, easy to be practiced indoors and on open spaces. In the recent years hydroponic has emerged as a new technology to grow plants. Agriculture has been on the forefront of every country’s economy.
