Acne vulgaris is a chronic inflammatory disease, and its treatment is challenging due to the multifactorial etiology and emergence of antibiotic-resistant Propionibacterium acnes strains. This study was focused to reduce antibiotics usage and find an alternate therapeutic source for treating acne. Lipid extracts of six Chlorella species were tested for inhibition of lipase, reactive oxygen species (ROS) production, cytokine production using P. acnes (Microbial Type Culture Collection 1951). Lipase inhibitory assay was determined by dimercaprol Tributyrate - 5, 5′- dithiobis 2-nitrobenzoic acid method and ROS production assay was performed using nitro-blue tetrazolium test. The anti-inflammatory activity of algal lipid extracts was determined by in vitro screening method based on inhibition of pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-α) produced by human peripheral blood mononuclear cells. Minimum inhibitory concentration (MIC) values of lipid extracts were determined by microdilution method, and the fatty acid methyl esters (FAME) were analyzed by gas chromatography-mass spectroscopy. Chlorella ellipsoidea has the highest lipase inhibitory activity with 61.73% inhibition, followed by Chlorella vulgaris (60.31%) and Chlorella protothecoides (58.9%). Lipid extracts from C. protothecoides and C. ellipsoidea has significantly reduced the ROS production by 61.27% and 58.34% respectively. Inhibition of pro-inflammatory cytokines TNF-α showed the inhibition ranging from 58.39% to 78.67%. C. vulgaris has exhibited the MICvalue of 10 μg/ml followed by C. ellipsoidea, C. protothecoides and Chlorella pyrenoidosa (20 μg/ml). FAME analysis detected 19 fatty acids of which 5 were saturated fatty acids, and 14 were unsaturated fatty acids ranging from C14 to C24. The results suggest that lipid extracts of Chlorella species has significant inhibitory activity on P. acnes by inhibiting lipase activity. Further, anti-inflammatory reaction caused by the pathogen could be reduced by the inhibiting the production of ROS and inflammatory mediators TNF-α and exposes new frontiers on the antiacne activities of Chlorella lipid extracts.

To isolate and quantify the protein and reducing sugar content of the cassava roots together with the antioxidant potential assays, which also included the inhibitory values on free radicals. The cassava roots were pulverized and extracted with both aqueous and organic extraction phases. The total protein content and reducing sugars and the flavonoid contents were estimated as per the protocol for all the four extract fractions. In addition, the free radical scavenging activity and SOD assay was done on all the four extracts. The total polyphenol content and the antioxidant potential assay was also estimated and to correlate the positive relation between the polyphenol content and the antioxidant power. The aqueous extract showed more content of reducing sugars and total protein content and flavonoids. The free radical scavenging activity was also more for the aqueous extract. In contrary the SOD activity was more towards the hexane fraction than the other three extraction phases. There is also positive correlation observed between the polyphenol content and the antioxidant power of the extracts. The cassava, a staple food though lacks the vitamin C content and is responsible for malnutrition among the consumers, it still has a good load of antioxidants which can make the plant a natural protective towards stress related diseases.

Klebsiella pneumonia carbapenemases (KPCs) are class A variant of β -lactamase enzymes capable of hydrolyzing all known β -lactam antibiotics. Worldwide spread of KPC producing strain makes them a potential threat for current antibiotic based therapy. In this study, we isolated the K. pneumoniae from the urine samples and screened for antibiotic resistance. Then molecular amplification techniques PCR was used for identification of KPC gene in these isolated samples. The PCR results coordinate with the antibiotic susceptibility testing and KPC positive isolates showed a multidrug resistant. Considering the potential for rapid horizontal and vertical transmission of KPC genes, prompt recognition is critical. This study validated a rapid, sensitive, and specific PCR assay for the detection of KPC gene.

Methicillin-resistant Staphylococcus aureus is one of the most important causes of hospital infections worldwide. High-level resistance to methicillin is caused by the mecA gene, which encodes an alternative penicillin-binding protein. S. aureus is an important cause of bloodstream infections and a leading cause of severe health care-Associated infections. Laboratory diagnostics S. aureus is a Gram-positive, catalase positive aerobic or anaerobic coccus showing hemolytic and large yellow colonies. S. aureus strains resistant to methicillin and many other antibiotics are major causes of nosocomial infections worldwide. It is of great necessity to check for those genes and check for the potential to clone partial or major fragments into vectors, which can be a potential candidate for DNA vaccines. Novel methods are being developed for the production of antibodies to specific antigens and thus helping in the process of development of protein-based vaccines. mecA (methicillin-resistant) gene was isolated and ligated into pTZ57R/T cloning vector. The ligated product was then cloned into DH5α strain and allowed to propagate. The plasmids thus cloned were purified and later expressed for the gene of interest in an expression vector. The proteins specific to the gene of interest was then isolated and purified. This proteins purified can in turn be used for protein-based vaccines. © 2014, Asian J Pharm Clin Res.

Since the mono gastric animals are not capable of metabolizing phytate, a rich source of Phosphorus, undigested phytate is excreted in manure without absorbed for metabolism and poses serious phosphorus pollution in the environment. Therefore, supplementation of phytases into animal feed is expected to solve the above problems. The present investigation deals with cloning and expression of a phytase-PhyL gene from Bacillus licheniformisin in E. coli strain DH5 alpha to facilitate large scale production of this enzyme. DNA was isolated from Bacillus licheniformis ATCC14580 and the phytase-PhyL gene was amplified. The amplified gene was cloned in ready to ligate cloning vector and cloning was confirmed by colony PCR and plasmid digestion. The reported and confirmed clone in this study will be useful in resolving the possible extensive production of recombinant phytases by means of fermentation. This cost effective phytases can be utilized as a feed supplement in animals.

Although disinfection methods currently used in drinking water treatment can effectively control microbial pathogens, research in the past few decades have revealed a dilemma between effective disinfection and formation of harmful and to consider innovative approaches that enhance the effectiveness. With the rapid advancement of nanoscience and nanotechnology, detailed knowledge of interactions between engineered nanomaterials and cells, tissues and organisms have become increasingly important, especially in regard to possible hazards to human health. The study was mainly designed to study the effect of silver and gold nanoparticles against the enterococcal pathogens. The organisms were also tested against the antibiotics to prove of their susceptibility toward the drugs. The enterococcal pathogens studied here showed a positive response for all the drugs used. The silver and gold nanoparticles are studied in this context to prove of their effect on the bacterial pathogens. Gold and silver particles are studied separately and are found to show some significant effect on the growth of bacteria. The pathogens studied showed susceptibility toward both the particles (gold and silver). And the effect of the nanoparticles was completely dose dependent, i.e., the effect was found to be more at higher concentration. All effects were statistically significant at the 0.05 significance level. There was a significant effect of the nanoparticles (gold and silver) among the four different concentrations remembered at the p<0.05 level. Gold nanoparticles showed a significance to the concentration (F [1,7]=13.36364, p=0.035353). © 2015, Asian Journal of Pharmaceutical and Clinical Research. All rights reserved.

India has one of the largest pools of hepatitis B-infected patients. The presence of HBs Ag in serum or plasma is an indication of active Hepatitis B infection either acute or chronic. Quantitative detection of Hepatitis B virus (HBV) DNA in serum by real time polymerase chain reaction (PCR) assay emerged as a gold standard in guided anti viral therapy. Evidences are suggestive of association of HBV genotype in liver dysfunction. We evaluated the performance as well as usefulness of both ELISA and PCR for detection of the major blood borne pathogen, HBV in southern India. First ALT and AST enzymes level was determined to check liver function. Serum of patients with chronic hepatitis B (HBsAg positive) and healthy individuals were tested both quantitatively and qualitatively. 4.5% of participants were HBsAg Positive by ELISA, while 7.5% of participants showed HBV DNA in real time PCR.
