The aim of the present study was to prepare sustained release matrix tablets of lornoxicam to make drug in sustained form so as to prolong its elimination time for the effective treatment of rheumatoid arthritis, and also in the management of ankylosing spondylitis, acute sciatica and low back pain. The present investigation demonstrates that, use of hydrophilic and hydrophobic polymers could be successfully employed for formulating sustained release matrix tablets of Lornoxicam. Optimized formulation containing HPMC K100M and Ethyl cellulose at optimum ratio had successfully sustained the drug release for 24 h. Matrix tablets of optimized batch had in vitro drug release. It was observed that the optimized matrix tablets of optimized batch shows better flow property by studying various pre-compression parameters. Thus, sustained release matrix tablets of Lornoxicam using biocompatible polymers were successfully formulated, evaluated and found to be suitable candidates in extending the release of the drug from the matrix tablets.

‘‘Proteomics’’, is the emerging technology leading to high-throughput identification and understanding of proteins. Proteomics is the protein equivalent of genomics and has captured the imagination of biomolecular scientists, worldwide. Because proteome reveals more accurately the dynamic state of a cell, tissue, or organism, much is expected from proteomics to indicate better disease markers for diagnosis and therapy monitoring. Proteomics is expected to play a major role in biomedical research, and it will have a significant impact on the development of diagnostics and therapeutics for cancer, heart ailments and infectious diseases, in future. Proteomics research leads to the identification of new protein markers for diagnostic purposes and novel molecular targets for drug discovery.  Though the potential is great, many challenges and issues remain to be solved, such as gene expression, peptides, generation of low abundant proteins, analytical tools, drug target discovery and cost. A systematic and efficient analysis of vast genomic and proteomic data sets is a major challenge for researchers, today. Nevertheless, proteomics is the groundwork for constructing and extracting useful comprehension to biomedical research. This review article covers some opportunities and challenges offered by proteomics.

Aim: Woodfordia fruticosa (Lythraceae) commonly called as 'Dhatakipuspha' in India. In Ayurveda, The fresh flower of W. fruticosa has been reported to stop bleeding in emergency cuts, while the dried flower powder to heal wounds more efficiently. Traditionally Woodfordia fruticosa Kurz is used in wound healing by tribes of Chhattisgarh, India. There was no scientific evidence justifying the use of Woodfordia fruticosa for treating wounds, therefore the present study was aimed at evaluation of wound healing activity of the plant. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. Materials and Methods:In the present study the flowers of Woodfordia fruticosa were studied for wound healing activity by incorporating the methanolic and total aqueous extract in simple ointment base B.P. in concentrations of 1% (w/w) and 2% (w/w). Ointments were also prepared using yashad bhasma (1.25% w/w) (equivalent zinc concentration 0.95% w/w) and yashad bhasma (0.625% w/w) (equivalent zinc concentration 0.45% w/w and 0.56% w/w) in combination with methanolic and total aqueous extract (1% w/w) in simple ointment base B.P. Wound healing activity was studied in the wound models in rats viz. excision and incision. In case of the excision wound model, wound contraction, period of epithelization and hydroxyproline content in the scab were studied, while incision wound model was evaluated by determining tensile strength of the newly formed skin. Results: Treatment of wound with ointment containing 2% (w/w) the methanolic and total aqueous and yashad bhasma (0.625% w/w) in combination with the methanolic and total aqueous extract (1% w/w) exhibited significant (P < 0.001) wound healing activity. The activity of the formulation may be due to the tannins present in the methanolic and total aqueous extract and zinc ions from the yashad bhasma which play major role in wound healing process. Conclusion:The methanolic and total aqueous extract exhibited good wound healing activity probably due to presence of tannins constituents and also due to presence of Zinc in Yashad bhasma.

To determine antimycobacterium and dTDP rhamnose inhibitor activity of the synthesized azetidinone, thiazolidinone derivatives of thiazole, we studied different derivatives for the activity. One pot synthesis of 2-amino-4-methylthiazole-5-carboxylic acid ethyl ester has been carried out and synthesized different derivative compounds. Compounds were tested for antimicrobial activity against different strains of microorganism and antitubercular activity against M. tuberculosis H37Rv. Compounds 7c, 7d, 7i, 8d, 8e, 8g and 8h, were showed antimicrobial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhosa using Gentamycin as standard, while 7b, 7e, 7f, 7i, 8b, 8e, 8f and 8i showed very strong antimycobacterial activity using rifampicine as a standard. Thiazole derivatives especially with carbonyl group scaffold inhibit an enzyme RmlC, which is an essential component for the biosynthesis of dTDP-rhamnose and produce good antimycobacterium and antimicrobial activity.
