Abstract:-
The succession of necrophilous insects on Sus scrofa Linnaeus kept in two different environments viz., grassland and aquatic were investigated. The purpose of this study was to investigate the decomposition rate, insect succession, taxonomic identification and to study the life history of Chrysomya megacephala (Fabricius, 1784) on two pig carrion. Three species of Calliphoridae i.e. Chrysomya rufifacies (Maquart), Calliphora vicina Robineou-Desvoidy and Chrysomya megacephala (Fabricius) were collected from the two pig carrion. The species found to be more pronounced in both the environment was Chrysomya megacephala (Fabricius). Due to their abundance in both the environments life history has also been noted during whole decomposition. A total number of 462 specimens were collected from the grassland and 476 from the aquatic environment. The specimen collected belonged to Diptera, Coleoptera, Hymenoptera, Dermaptera and Arachnida. Insect fauna associated with aquatic environment were observed more than grassland environment.

Abstract :-
Two hundred adult hip bones (100 males and 100 females) of known sex were obtained at random from the skeletal collection of Department of Anatomy. Measurements were taken with the help of Verniear Caliper, and divider. In this study six parameters were considered including three old parameters and three new parameters. For every parameter, the mean and standard deviation (S.D) was calculated and the range noted. Demarking points were worked out from calculated ranges, i.e. mean + 3 S.D. (Singh and Potturi). The percentage of the bones identified by each demarking point in both sexes was estimated from this material. The observations were recorded. The values obtained for various parameters were compared. It is concluded that among the various criteria pubic crest length and Pelvic and sacral part of chiloticline was found to be useful criteria while distance from anterior inferior iliac spine to iliopubiceminence and to pubic tubercle was useless criteria. Key Words: Iliac spine, Sex determination.

Abstract:- Background: Pseudomonas aeruginosa (P. aeruginosa) is a gram negative bacterium that continues to be a major cause of opportunistic nosocomial infections, causing around 9-10% of hospital infections. The rapid increase of drug resistance in clinical isolates of this opportunistic human pathogen is a worldwide concern. Unfortunately, P. aeruginosa demonstrates resistance to multiple antibiotics, thereby jeopardizing the selection of appropriate treatment. Aims & Objectives: This study was undertaken to find out the antibiotic resistance pattern of pathogenic isolates of P. aeruginosa from various specimens. Settings and Design: Hospital based Prospective study. Materials & Methods: 124 pseudomonas positive samples from various samples were included in this study. Antibiotic susceptibility pattern was tested as per CSLI guidelines. Statistical Analysis: The results were presented using proportions. Results: Highest percentage of P. aeruginosa was isolated in pus samples. The resistance was highest for ceftazidime (79%), followed by ceftriaxone (73%), cefepime (73%), cotrimoxazole (72.3%) and lowest for imipenem (5.1%). The rate of aminoglycoside resistance was found to be relatively high (amikacin- 46.7% & gentamicin 49.5%). Conclusions: P. aeruginosa is one of the most important bacterial pathogen seriously contributing to the problem of healthcare associated infection. Amikacin seems to be a promising therapy for pseudomonas infection. Hence its use should be restricted to serve nosocomial infections in order to avoid rapid emergence of resistance strains. Hence there is a need to emphasize the rational use of antimicrobial & strictly adhere to the concept of reserve drugs to minimize the misuse of available antimicrobials.

Abstract:-
Circadian rhythm is the internal, 24-hour clock and is coordinated by a pacemaker located in the hypothalamic suprachiasmatic nucleus (SCN), which is synchronized to the environmental light/dark cycle of 24 h. Circadian clock influences nearly all aspects of physiology and behavior, including sleep-wake cycles, cardiovascular activity, endocrine system, body temperature, renal activity, physiology of the gastrointestinal tract, and hepatic metabolism. Similar clock oscillators have been found in peripheral tissues such as the liver, intestine, heart, and retina. There are two major ways by which metabolic information may reach the SCN: 1) the sympathetic and parasympathetic branches of the autonomic nervous system; and 2) hormones or nutrients, such as glucose, that cross the blood brain barrier. Circadian rhythm disorders are disruptions in a person’s "internal body clock" that regulates the 24-hour cycle of biological processes in animals. The key feature of circadian rhythm disorders is a continuous or occasional disruption of sleep patterns leading to various disorders like delayed sleep phase syndrome, advanced sleep phase syndrome, jet lag and shift work disorder. Disruption to rhythms in the longer term is believed to have significant adverse health consequences on peripheral organs outside the brain, particularly in the development or exacerbation of cardiovascular disease, type 2 diabetes and tumor development in several ways, by altering immunocompetence, growth factor expression or the endocrine environment. Future research will continue to focus on expanding our understanding of how brain and peripheral clocks coordinately regulate metabolic processes and the impact of circadian rhythms in human health and disease. The further exploration of molecular mediators that coordinate circadian, metabolic, and endocrine systems may lead to improved therapeutics and preventive interventions.
