Raw sugarcane juice is a popular drink in India but in most cases not available in hygienic condition. Attempts had been made to preserve sugarcane juice by pasteurization followed by packaging in flexible packs and the time of exposure pH, acidity and brix of sugarcane juice were measured. Pasteurization of a number of samples were carried out in conical flasks at different temperatures like 80°C, 85°C, 90°C for different time intervals like 30 Second, 1 minute, 2 minute, 5 minute and then pH, acidity and brix were estimated and keeping the flask in 2 different conditions like refrigerated temperature (4°C), room temperature (30 °C). Another set of experiments were carried out by adding sodium metabisulfite of different concentrations normally 500 ppm and 1000 ppm. Initially the quality of sugarcane juice with respect to pH, acidity and brix were evaluated. Similarly the quality of the processed sugarcane juice was also evaluated. The best result with respect to pH, acidity and brix were obtained from the juice which was pasteurized at 90°C for 5 minutes and stored at refrigerated temperature and room temperature after 25 days acidity were found to be 0.072 mg/ml and 0.019 mg/ml, pH 4 and 4.57, brix 10 in both the cases.

The puropose of this research was isolating the native strains of microorganism secreting extracellular thermostable α-amylase in soil of Kolkata (West Bengal, India). Among all the tested culture. Bacillus subtihs (Gram-positive bacteria) and fungus Aspergillus tamari selected for the study. Carbon source (starch, 1% w/v) and nitrogen source (peptone, 0.1% w/v) were used and secretion optima for Bacillus subtilis and Aspergillus tamari were achieved at temperature 60RC, pH 7.0 and 5.0, and incubation time 72h and 120h respectively. Optimum activity of a-amylase from Bacillus subtilis and Aspergillus tamari were 1.0936 U/mL and 1.328 U/mL, at pH 7.0 and 5.0, temperature 60°C and 50°C respectively. These strains produced thermostable a-amylase with characteristics suitable for application in starch processing and food industries.

Our nervous system works like electrical circuit. All our muscle movement and activities have been controlled by brain when it is electrically stimulated. In normal human body brain gets stimulated by its own physiological mechanism. What happens if we stimulate the brain from outside artificially by electrical energy? Can this artificial electrical stimulation be used as a treatment for some nerve damage in the brain? Yes, it can be. It is called brain pacemaker.

Stroke is a leading cause of death and disability all over the world. Prevention is the best treatment than having a stroke. Though all the factors are not modifiable, but we need to know some modifiable risk factors to reduce the incidence of this crippling disease.

Deep brain stimulation (DBS) is an universally accepted therapy for medically refractory Parkinson’s disease (PD). Both globus pallidus internus (GPi) and subthalamic nucleus (STN) stimulation are effective in improving the symptoms of PD and reducing dyskinesias. STN DBS is the most commonly performed operation for PD as compared to GPi DBS. Ventral intermediate nucleus (Vim) DBS is used occasionally in selected cases as an alternative for tremor predominant PD patients.
Patient selection is very much essential in achieving good outcomes. Good response to levodopa challenge is most important predictor of favourable long-term outcomes. The DBS surgery is typically performed in an awake state and involves stereotactic frame application, CT/MRI imaging, anatomical targeting, electrophysiological confirmation and intra-operative clinical monitoring for efficacy and adverse effects after intra-operative stimulation and implantation of the DBS lead and pulse generator.
Physiological verification is achieved by microelectrode recording followed by implantation of the DBS lead and intraoperative test stimulation to assess benefits and side effects. The various aspects of DBS surgery has been discussed.
