Simple, precise, economic, less time consuming visible spectroscopic method for Deflazacort was developed by using 2, 2- Bipyridyl and Ferric Chloride. The absorption maximum of the chromogen was found to be 540 nm. The developed method was obeying Beer Lambert's law in the range of 50-250 μg/ml concentration. The method has also been statistically evaluated and the results were within the regulated limits. Molar absorptivity, Sand ell's sensitivity and correlation–co-efficient were found to be 1.406 x 103, 0.143 and 0.999 respectively and the method is free from the interferences of other additives present in the tablet formulation.

The present work was carried out to examine the binding efficiency of pyrethroids-Cypermethrin, Flumethrin, and Deltamethrin on CYP41, encoding cytochrome P450 of Rhipicephalusannulatus by computational docking studies. The protein structure of CYP41 was predicted using Phyre2 web portal, and the structure validation was performed using SAVES4 server. The predicted structure was docked with different commonly used pyrethroids using GLIDE. Among the acaricidesdocked, Flumethrin showed the best binding energy. There are no considerable variations among the binding energy levels and scores of the acaricides with the target molecule. From the study, we inferred that CYP41 is an effective target for the selected pyrethroids.

Eating Disorders are psychological disturbances associated with irregular eating habits and severe distress about body weight or shape [1]. They result in inadequate or excessive food intake which can ultimately damage an individual's well-being [1]. Eating Disorders are complex disorders, influenced by a facet of factors. It is generally believed that these disorders are combinations of biological, psychological, and environmental disturbances [1]. Eating disorders can develop during any stage in life but typically appear during the young adulthood. These conditions are treatable, however; the symptoms and consequences can be fatal if not addressed properly [2]. The most common eating disorders include anorexia nervosa, bulimia nervosa and binge eating disorder [2]. In this study we sought to review these common eating disorders.

Tuberculosis (TB), which is one of the oldest diseases known to affect humans and is likely to have existed in prehominids, is a major cause of death worldwide. This disease is caused by bacteria of the Mycobacterium tuberculosis complex and usually affects the lungs, although other organs are involved in up to one third of cases. If properly treated, TB caused by drug susceptible strains is curable in virtually all cases. If untreated, the disease may be fatal within 5 years in 50 -65% of cases. Transmission usually takes place through the airborne spread of droplet nuclei produced by patients with infectious pulmonary TB. With a population of about 1252 million, India is the largest country in the Region..............

The lymphatic system is an important part of the immune system. It helps in removal of interstitial fluid and its dissolved substances from the tissues, initiates and coordinates immune responses for removal of cellular debris and helps to absorb fats and other substances from the GI tract. Consequently, improving the lymph movement is of a great benefit. Unlike the circulatory system, the lymphatic system does not have any pumping mechanism to move the lymph and therefore its upward movement depends upon the movement of the muscles surrounding the lymph vessels.[1],[2] Other factors like sedentary lifestyle, stress, tissue injury, etc, restrict the flow of lymph. Enhancement of the lymph movement helps in improving the detoxification process, regenerating the burned or damaged tissues and many other benefits, all of which prove to improve human health status. Hence, it is important to explore and understand the various ways by which the lymph movement can be enhanced. This review focuses on the various techniques which help enhance the lymph movement and various benefits of enhanced lymph movement.

Pituitary hormones GH and PRL have been used as external stimulating agents in farm animals to increase the yield of milk and meat. Here, a simple, protocol for purification of Growth Hormone (GH) and Prolactin (PRL) from the pituitary glands of Indian domestic goats (Capra hircus) has been described. Extraction of pituitaries with ammonium sulphate coupled with QAE-Sephadex anion exchange chromatography provided purified GH. The GH preparation was found to be pure in SDS-PAGE analysis and immuno-reactive to anti-buffalo GH antibody in ELISA. QAE-Sephadex was also useful in fractionating goat GH into different charge isoforms. PRL was purified from an alcoholic extract by gel-filtration chromatography on S-200.The PRL preparation was found to be pure in SDS-PAGE analysis................

Nateglinide is a novel, exceedingly physiologic, glucose regulator lately ratified for the handling of type-2 diabetes mellitus. Nateglinide has a rapid commencement and diminutive duration of insulinotropic action those outcomes in decline of glucose level. The persistence of this study is to develop a floating tablet of Nateglinide to boost its bioavailability and sustained action. Tablets were prepared by direct compression method, using Ethyl cellulose, Carbopol 930 and pvpk-30. Tablets were evaluated for in vitro drug release features like hardness, thickness, friability, weight variation and floating properties. Additional tablets were evaluated for In vitro drug release studies for 24 hours. The tablets unveiled controlled and prolonged release while moving over the dissolution medium, polymer rearrangement played a critical role.

The present research work focuses on the development and evaluation of theophylline press coated tablet, showing controlled release pattern consigned with chronotherapeutics aspects. Provided HPMC K100LV and HPMC K4M were used in the different formulation as coating polymer for development of press coated tablet for controlled release. The formulation powder mixtures were evaluated for pre-compression parameters such as angle of the repose, bulk density, tapped bulk density, Carr's index and Hausner's ratio. Batches containing combination of HPMC K100LV and K4M controlled the drug release better at low concentration of high viscosity grade and it was used to optimize the formulation for pulsatile release...........

OBJECTIVE. The purpose of this study was to obtain normative data for Motor-Free Visual Perception Test (MVPT) in Chennai children.To find out the performance difference between genders. METHOD. Three Hundred and Thirty One typically developing children comprising of 167 girls and 164 boys were taken from normal school situated in various parts of Chennai. RESULTS. No significant difference (F=0.150, p=0.698) between gender on MVPT performance. Pearson correlation exhibits positive correlation (r= 0.746, p<0.001) between age and raw. CONCLUSION. Cultural influence has been scrutinized in visual perception. It also suggested that there was no gender difference and raw score increases as age matures. This study concluded that there is a strong need to ensure that norms for visual perceptual test are appropriate for specific cultural group being assessed. The norms produced in this study form the baseline for MVPT and can be used for screening and therapeutic purpose.

The narrow tunable emission spectra and high photo-luminescence efficiency make QDs potentially the most practical candidates for making quantum-dot light emitting devices. In the last decade or more, a considerable amount of research has been focused on developing highly efficient QD-LEDs.[1-4] Quantum dot led have great potential for being used for energy efficient high colour quality thin-film display and solid-state lighting. The wide absorption spectrum, band gap tunability and cheap solution processibility make quantum-dot a promising candidate for solar cells as well. Additionally, solution-processed quantum dot allows processing onto light-weight exible substrates through spin coating, spray-coating, reel-to-reel printing and inkjet printing which can potentially reduce the fabrication and packaging cost[5].
