Memory loss is a typical symptom of generalized anxiety disorder, a condition that affects millions of individuals. Memory loss with anxiety can be quite distressing, but if you can find strategies to address the anxiety, your memory may improve as well. In this study, the effects of Nauclea latifolia extract, taurine and vitamin E supplementation on object identification and stress-induced anxiety in Albino rats exposed to water immobilisation stress were investigated. 24 rats weighing between 100 and 120 grams were employed. The control group (A), received 1ml/kg pure water. Vitamin E was given to Group B at a dosage of 0.2 ml/kg. Group C received 200mg/kg taurine, while Group D received 200mg/kg Nauclea latifolia extract. For three weeks, the administration was completed. The rats were famished for 24 hours before the stress process began. The rats were sedated with chloroform vapour, and then restrained using a hardwood board (25 by 18 cm) with the four limbs fixed sideways, then dipped for two hours in water up to the xiphoid level. During the training phase, the taurine group examined the novel object the most (64.9 percent), followed by the Vitamin E group (63.90 percent), when compared to the Nauclea latifolia (52.75 percent) and the control groups (54.76 percent). The consolidation phase similarly, revealed that, taurine and Vitamin E groups explored the novel object the most (71.52 percent) and (70.05 percent) accordingly. In the anxiety model, Nauclea latifolia, taurine and vitamin E groups showed significant increase in time spent on closed arms. This study has shown that, when rats are treated to water immersion restraint stress, administration of Nauclea latifolia extract, taurine, and vitamin E, may decrease stress-induced anxiety-like behaviours. The significance of this study is that, administration of taurine, vitamin E and Nauclea latifolia extract may prevent stress-induced memory impairment.

This study was conducted to evaluate stress responses of juveniles African catfish exposed to transportation for 6hrs duration in plastic bags. The fish were separated into two groups; control and treatment. The fish in the treatment group were placed in nylon bags with 7.5 liters of oxygenated freshwater in each bag. The bags were labeled according to the duration of transport as T1, T3, and T6 and the transportation was carried out in triplicate while the control group was not transported. Blood and liver samples were collected as follows; immediately after transportation, three days after transportation and six days after transportation for biochemical and molecular assay. In African catfish juveniles, transportation showed a substantial (P <0.05) increase in SOD and CAT mRNA expression shortly after transportation and a considerable (P <0.05) decrease on the third and sixth days after transportation. The result of the antioxidant profile of SOD, CAT, and GSH indicated significant increase (P <0.05) immediately after transportation, third and sixth day after transportation. It is concluded that live transportation process is a significant stressor as it results in significant changes in biochemical parameters and liver of African catfish juveniles.
