Comparative change in P300 indices following antidepressant treatment in patients with major depressive disorder.

Context: Cognitive disturbance is seen in patients with major depressive disorder (MDD). Event-related potential can assist in measuring the neurocognition, and P300 is the most commonly used noninvasive electrophysiological parameter for measuring cognition.

Aims: The aim of this study is to assess the baseline P300 parameters, Hamilton Rating Scale for Depression (HAM-D), and Montgomery-Asberg Depression Rating Scale (MADRS) scores and compare them with their levels after 3 months of antidepressant therapy.

Comparison of Pulmonary Function Test in Petrol Pump Worker and Auto-rickshaw Driver.

Background: Rapid rise in petrol pump filling station is seen in the last decade, and air pollution had increased drastically. Air pollutants and components in petrol may have delirious effect on respiratory health.

Cardiorespiratory response to aerobic exercise programs with different intensity: 20 weeks longitudinal study.

Context: participation in regular intensive exercise is associated with a modest increase in left ventricular wall thickness and cavity size. The magnitude of improvement depends on frequency, intensity, type, and duration of exercise program.

Aims: to determine the effect of sports training on LV morphology and function, lung function, and to know the intensity of the exercise program enough for these changes.
