Optogenetics (a branch of biotechnology) is a biological tool used in the field of neuroscience that encompasses a combination of techniques from optics and genetics to study the functioning of individual neurons in a living tissue. Spatio-temporal precision in neuronal control can be achieved using optogenetic actuators or reporters and sensors or indicators. The present review highlights the brief history of optogenetics, opsins- the functional unit in optogenetics, and the design of optogenetic experiments to study behaviour in normal function or disease models. The review also discusses the limitations of the technique and its applications in various behavioural and neuropsychiatric disorders such as anxiety, fear, depression, addiction, autism and Parkinsonism. Looking back at the rate of progress over the last few years, it is reasonable to predict and believe that the molecular techniques for optogenetics will continue to evolve rapidly and that the applications of these methods will continue to...

Ginkgo Biloba is a potent antioxidant dietary source for human health. Oxidative stress through generation of free radicals damages the myocardium in different experimental condition. The present research was designed to evaluate the cardio protective role of chronic oral administration of Ginkgo biloba leaf extract against Isoproterenol induced myocardial injury. Male Wistar albino rates were randomly divided into five groups (n = 6) and treated as per treatment protocol with three different dose of Ginkgo biloba extract (125, 250, and 500 mg/kg b.w.) orally for thirty days. At the end of the treatment all the rats (except control rats) were administered with Isoproterenol (85 mg/kg) two consecutive days and subjected to biochemical and histopathological estimation. Isoproterenol (group II) induced the oxidative myocardial damage via alteration in the endogenous antioxidant enzymes and myocardial marker enzymes. Ginkgo biloba extract in all three dose (group III, IV and V) shows protective mechanism via decreasing thiobarbituric acid reactive substance (TBARS) and enhancing the endogenous antioxidant enzymes ( reduced glutathione (GSH), superoxide dismutase (SOD)...

Introduction: Pharmaceutical care entails the work of addressing patient’s medication related needs and problems. The involvement of the pharmacist in India in this regard has been somewhat restricted, contrary to trends in developed countries. Materials and methods: Questionnaire-based explorative, semi-quantitative study involving Doctors, Pharmacists and Nurses of the study department in the following sequence; Design of questionnaire, Pre-testing/validation, Administration, Collection, Evaluation & Interpretation. Results: Out of total 90 questionnaires distributed among health care providers the response rate was measured as 63.3% and less than 40% of the Health Care Providers could answer correctly to the first section of questionnaire intended to assess the knowledge regarding pharmaceutical care. In the perception part 73.3% of doctors agreed and 20% strongly agreed that pharmaceutical services provided by clinical pharmacist can improve the quality of patient care in hospital settings. 66.6% agreed and 26.6% strongly agreed that clinical pharmacist as a part of medical team will minimize medication errors. 73.3% agreed and 20% disagreed that doctors can allow pharmacists to be available with...

In the present study, pharmacognostical, qualitative and quantitative phytochemical analysis of Azardirachta indica, Cassia auriculata, Moringa oleifera and Curcuma longa was done. The results showed the presence of various vital secondary metabolites. Primary metabolites was found to be more in Cassia auriculata whereas the secondary metabolites content was higher in Azardirachta indica. In the selected plants, the alkaloid content was found to be high followed by flavonids, proline. This proves that, the selected plants posses good medicinal property and can be recommended for treatment of...

The use of microwave irradiation in grafting of synthetic polymers onto natural polysaccharides is a popular method. It reduces all the limitations of conventional method of grafting like use of toxic solvents as well reduces reaction time for grafting methods. Microwave irradiation also increases the yield of grafting. Also the microwave grafted polymer has better properties as compared to polymer grafted by conventional method. The purpose of this review is to highlight the various recent modifications of grafting and its further applications in pharmaceutical...
