A Study of Swelling Pressure of Soil along Left Bank Canal of BARGI Dam

When an expansive soil attracts and accumulates water a pressure known as swelling or expansion pressure builds up in the soil and it is exerted on the overlying materials and structures if they are any. On the other hand, tests to determine index properties are quite simple and less expensive. A correlation for the quick analysis of swell pressure of soil from the graph generated between different soil engineering parameters such as (OMC, MDD, PI, ACTIVITY OF SOIL and RL) and SWELLING PRESSURE2 ( inKPa). In this study, an attempt is made to correlate swell pressure with reduced depth of the location along the left bank canal

Effect of Bio-degradation and Non Degradable Substances in Environment

Non-Biodegradable substances produce the greenhouse gasses, methane and carbon dioxide. Growing plants and trees on top of a landfill, a process known as ‘Phyto capping\u27, could reduce the production and release of these gasses. In certain parts of the world, it remains the most economical and simplest method of waste disposal. Biodegradation of organic matter in a landfill site occurs most rapidly when water comes into contact with the buried waste. An important step in the drive is to remove environmentally harmful materials from waste streams and drinking water. A synthetic clay known as swelling mica has the ability to separate ions of radium, a radioactive metal, from the water. The finding could have implications for radioactive and hazardous waste disposal, particularly in the cleanup of mill tailings left over from the processing of uranium for the nation\u27s nuclear industry. The tailings contain radium and heavy metals

Anti-Depressant Activity of Zizyphus xylopyrus

The present study was undertaken to investigate the effect of ethanolic extract (ext.), ethyl acetate (EA) fractions and precipitate fraction (ppt.) of total ethanolic extract of Zizyphus xylopyrus on depression in rats. In the present study, the antidepressant effect of Zizyphus xylopyrus was examined using two behavioral models, the forced swimming test (FST) in rats and tail suspension test (TST) in rats.Ethanolic extract when administered at an acute dose of 50 mg/kg of body weight (P<0.01) reduced the immobility time by 10 and 15 seconds as compared to the immobility time of control in both the screening models. Similarly EA reduced latter by 30 and 35 secs. The ppt. fraction showed the best activity, reducing the immobility time by 50 and 60 secs. in both the tests. These results showed that after standard i.e. Imipramine HCl (30 mg/kg), the ppt. fraction is potent amongst all the studied drugsThe present study clearly demonstrated that Zizyphus xylopyrus exerts an antidepressant effect in these two behavioral models. It may be due to present of flavonoids.Keywords: Zizyphus xylopyrus, Flavanoides, forced swimming test, tail suspension test

ISOLATED ENTERIC SPLENIC LESION IN AN IMMUNOCOMPETENT HOST: AN INTERESTING CASE REPORT

Splenic abscess is often an unrecognized complication of enteric fever. Diagnosis is difficult because of its rarity, insidious onset, and non-specific presentation. We report an interesting case of splenic lesion in an immunocompetent adolescent with no other comorbidities, who presented with history and clinical presentation more suggestive of tubercular etiology. However, culture from the CT-guided fine-needle aspirate grew Gram-negative bacilli, identified as Salmonella Typhi which was sensitive to ampicillin, cotrimoxazole, azithromycin, and ceftriaxone. He responded favorably with oral antibiotics without any further surgical intervention. High degree of clinical awareness with timely and appropriate microbiological evaluation helped into an early definitive diagnosis of enteric splenic abscess. This case highlights that in this era of emerging infections, we should not miss the atypical presentations of the endemic diseases. Safe and minimally invasive radiological intervention with good microbiological correlation is a successful spleen conserving treatment alternative to surgery in suitable patients of splenic abscess

Overview of Transdermal Medicated Patches with its research updates in preceding years

Innovations in transdermal drug delivery systems (TDDS) is an important influence to medical practice by providing advances in the delivery of treatment with existing conventional drugs and novel drugs. Transdermal drug delivery is one of the most promising methods for drug application. It has several benefits over conventional system to offer sustained drug release, avoidance of first pass effect, patient compliance, ease of application and removal in case of toxicity as well as decrease in the side effects as compared with conventional therapy. Transdermal patches are dosage forms which transport drug to viable epidermal and dermal tissues of the skin for local therapeutic effect while a very major fraction of drug is transported into the systemic blood circulation. Skin penetration enhancement techniques have been developed to improve bioavailability and increase the range of drugs for which topical and transdermal delivery. The purpose of this review is to introduce transdermal patches including type of transdermal patches, components of transdermal patches, method of preparation of TDDS, evaluation parameters, researches and development done on TDDS in last decade etc.  Keywords: Transdermal Drug Delivery System, Permeation Enhancers, Transdermal Patch, Polymer Matrix

Molecular Study of Glycoprotein (G) Gene Region of Rabies Virus from Spotted Deer, Delhi, India

Rabies is a viral zoonotic disease of public health importance in India. The disease is usually transmitted by a rabid animal bite, scratches and licks on broken skin and mucous membrane. Rabies is reported from all continents except Antarctica although prevalence is more in Asia and Africa. India is endemic for rabies virus (RABV) throughout the country except for islands of Lakshadweep, Andaman & Nicobar. In the present study, brain samples of clinically suspected animals obtained during the RABV outbreak at National Zoological Park, New Delhi, India, in 2016 were initially tested for rabies antigen by DFAT. All the 32 DFAT positive brain samples were then processed for RNA isolation. The extracted RNA was amplified for glycoprotein (G) gene of 590 bp by RT-PCR followed by nucleotide sequencing. Nucleotide alignment revealed only substitutions without any insertion or deletion. Amino acid alignment revealed replacement at four positions namely L244I, T264A, M310I and N375K. The amino acid change at position where Leucine is replaced by Isoleucine has not been observed in available RABV references of the G gene region either from India or other countries. This mutation was observed in all the samples included in the present study. A phylogenetic tree showed that all the study sequences belonged to Arctic like 1a lineage, in RABV genotype 1. In conclusion, RABV in the study region is acquiring genetic variation; which may have effect on the pathogenicity. This indicates that continued molecular surveillance of the circulating rabies virus strains should be carried out

INTERNATIONAL JOURNAL OF PHARMACY & LIFE SCIENCES Dendrimers-a novel drug delivery system

Abstract Dendrimers are the polymeric materials for targeted delivery of drug molecule. These are the highly branched nanoscopic structure for the potential delivery of bioactive. The structure of these materials has a great impact on their physical and chemical properties. As a result of their unique behaviour dendrimers are suitable for a wide range of biomedical and industrial applications. The bioactive agents can be easily encapsulated into the interior of the dendrimers or chemically attached i.e. conjugated or physically adsorbed onto the dendrimer surface, serving the desired properties of the carrier to the specific needs of the active material and its therapeutic applications. In addition to supplying a multivalent backbone for drug attachment, dendrimers also provide access to various new polymer architectures that are potentially relevant to drug delivery applications. Through this review we are mainly focusing on the various properties and applications of dendrimer in pharmaceutical sciences
