ANTIMICROBIAL ACTIVITIES OF FRESHWATER CYANOBACTERIUM, NOSTOC SP. FROM TAMDIL WETLAND OF MIZORAM, INDIA: AN IDENTIFICATION OF BIOACTIVE COMPOUNDS BY GC-MS
A freshwater microalga, Nostoc sp. isolated from Tamdil Wetland of Mizoram was tested for its algicidal, antibacterial and antifungal activity. Extracts were prepared with methanol, ethanol:water and dichloromethane:isopropanol and tested for their antimicrobial activity against nine microorganisms comprising of three chlorophycean algae (Chlorella vulgaris, Scenedesmus quadricauda and Selenastrum...
The purpose of this study was to investigate the effects of the Ramadan fasting and life rhythm eating rhythm on some elimination parameters, such as the antipyrine clearance, urinary volume and pH. A single oral dose of Antipyrine was administred to 14 healthy volunteers at 08:00 p.m. All the volunteers were submitted to four treatment phases; the first one was carried out 1 week prior to Ramad...
ASSESSMENT OF ANTIOXIDANT, CYTOTOXIC AND ANTIBACTERIAL ACTIVITIES OF DIFFERENT FRACTIONS OF CRUDE EXTRACT OF STEPHANIA JAPONICA STEM
The different fractions of crude methanolic extract of stem of Stephania japonica (Thunb.) Miers was evaluated for antioxidant, cytotoxic and antibacterial activities. The various fractions of S. japonica Stem i.e. Ethyl Acetate (EAJS), CHCl3 (CFJS), CCl4 (CTJS) and Petroleum ether (PEJS) were subjected to free radical scavenging activity. In this investigation, CFJS showed the most significant fr...
IMPACT OF NASAL CONTINUOUS POSITIVE AIRWAY PRESSURE ON C-REACTIVE PROTEIN IN OBSTRUCTIVE SLEEP APNEA PATIENTS
Obstructive sleep apnea (OSA) has been increasingly linked with cardiovascular risk factors. Mechanisms such as increased sympathetic activity and endothelial dysfunction have been implicated. There are many factors which are responsible for the cardiovascular morbidity in OSA patients they are Obesity, C-reactive protein (CRP) and lipid profile. To study the impact of nasal continuous positive ai...
The objective of this research was to develop and validate a simple, sensitive and specific Liquid Chromatography – Tandem Mass Spectrometry (LC–MS/MS) quantification of Varenicline in human plasma using Varenicline -D4 as Internal Standard (IS). The analyte was separated on a Zorbax SB-C18, 4.6 x 75 mm, 3.5 μm, 80 Å column with an isocratic mobile phase of 5mM ammonium formate: acetonitrile...
Tuberculosis (TB) is an ancient disease that has caused inestimable suffering and claimed millions of lives over the centuries. Resistant strains of Mycobacterium tuberculosis have slowly emerged especially in developing countries due to the lack of health care organisation in order to provide the long and costly treatment adapted to patients. In fact, 90% of all TB cases occur in the developing w...
CLINICOPATHOLOGICAL STUDY OF 115 CASES OF GLIOBLASTOMA MULTIFORME WITH SPECIAL REFERENCE TO GLIOSARCOMA
Background: Glioblastoma Multiforme is the commonest of all astrocytomas. It accounts for 12-15% of all intracranial neoplasm and 50-60% of all astrocytic tumors. Most common site of occurrence is cerebrum and age incidence is highest in fifth and sixth decade. Gliosarcoma constitutes 2% of all brain tumors, 5% of all astrocytomas and 8% of anaplastic astrocytomas. The cell of origin of sarcomatou...
Biofilm formation is prevailing in almost all bacteria. They are responsible to cause infections like Peritonitis, Cystic fibrosis, Endocarditis, Otitis media, UTIs. The infections caused by the biofilms forming bacteria that colonize the indwelling medical devices are a major source of patient morbidity and implant failure. The study on biofilm formation on indwelling medical devices is importa...
SYNTHESIS AND CHARACTERIZATION OF BIOLOGICALLY ACTIVE COMPOUND E-2-((2-AMINO PYRIDINE-3-YL) METHYLENE AMINO) ETHANE THIOL AND ITS METAL COMPLEXES
A new physiologically active compound E-2-((2-amino pyridine-3-yl) methylene amino)ethane thiol derived from the condensation of Cysteamine and 2-amino Pyridine 3-Carbaldehyde was synthesized and characterized by spectral techniques like IR, UV-Vis,1H- NMR, TG-DTA, ESR, CHN analyses. The complexes were further screened for their biological activity at Nishka labs and Nickel and Cobalt complexes we...
STUDY OF THE EFFECT OF MELATONIN ON RETENTION OF CONDITIONED AVOIDANCE RESPONSE AND ON ENHANCEMENT OF SEROTONIN MEDIATED BEHAVIOURAL RESPONSES AFTER ELECTROCONVULSIVE SHOCK (ECS) ADMINISTRATION IN RATS
Objectives: To obtain the data regarding the effects of melatonin on retention of conditioned avoidance response (CAR) and on enhancement of serotonin mediated behavioural responses after electroconvulsive shock (ECS) administration in rats. Methods: Forty rats after training for conditioned avoidance response by using Cook’s pole climbing apparatus were divided in four groups with ten rats in e...
