In a number of microbial pathogens that undergoes antigenic variation to evade the host’s immune attack, genes encoding surface antigens are located at subtelomeric loci, and recent studies have revealed that telomere components play important roles in regulation of surface antigen expression in several of these pathogens, indicating that telomeres play critical roles in microbial pathogen virulence regulation. Importantly, although telomere protein components and their functions are largely conserved from protozoa to mammals, telomere protein homologs in microbial pathogens and humans have low sequence homology. Therefore, pathogen telomere components are potential drug targets for therapeutic approaches because first, most telomere proteins are essential for pathogens’ survival, and second, disruption of pathogens’ antigenic variation mechanism would facilitate host’s immune system to clear the infection.

Diabetes mellitus: Exploring the challenges in the drug development process.

Diabetes mellitus has reached epidemic proportions and continues to be a major burden on society globally. The International Diabetes Federation (IDF) estimated the global burden of diabetes to be 366 million in 2011 and predicted that by 2030 this will have risen to 552 million. In spite of newer and effective treatment options, newer delivery and diagnostic devices, stricter glycaemic targets, better treatment guidelines and increased awareness of the disease, baseline glycosylated hemoglobin remains relatively high in subjects diagnosed and treated with type 2 diabetes. The search continues for an ideal anti diabetic drug that will not only normalize blood glucose but also provide beta cell rest and possibly restoration of beta cell function. The development of anti diabetic drugs is riddled with fundamental challenges. The concept of beta cell rest and restoration is yet to be completely understood and proven on a long term. The ideal therapeutic approach to treating type 2 diabetes is not yet determined. Our understanding of drug safety in early clinical development is primarily limited to “Type A” reactions. Until marketing authorization most drugs are approved based on the principle of confirming non-inferiority with an existing gold standard or determining superiority to a placebo. The need to obtain robust pharmaco-economic data prior to marketing authorization in order to determine appropriate pricing of a new drug remains a major challenge. The present review outlines some of the challenges in drug development of anti-diabetic drugs citing examples of pulmonary insulin, insulin analogues, thiazolidinediones and the GLP1 analogues.

Misoprostol is a versatile drug with an effective uterotonic effect on the postpartum uterine tissue and is used through various routes during the third stage of labor.A randomized prospective study was carried out to analyze the most effective route for misoprostol administration, with an emphasis on parturients’ acceptability and compliance, a possible shortening of the duration of the third stage of labor, minimization of blood loss and possibly reducing the incidence of potential side effects.The study groups comprised of 300 healthy parturients, divided randomly into three groups of 100 parturients each, who were administered misoprostol 400 ?g through the oral (O), rectal (R), and sublingual (S) routes, respectively, during the third stage of labor. Estimation of blood loss was measured in terms of fall in hemoglobin, hematocrit, and packed cell volume (PCV) levels, and duration of the third stage of labor was also compared.The mean duration for the third stage of labor was significantly shorter in group S (3.62 minutes) as compared to R (4.12 minutes), and O (4.94 minutes) (P = 0.02). The average blood loss was observed to be the least in the group S (210 ml) as compared to group R (230 ml), and group O. The incidence of shivering and fever was observed to be significantly higher (25 and 15%) in the parturients of group S (P < 0.05).All routes were equally effective in managing the third stage of labor, but administration of misoprostol through the rectal route evoked better acceptability, comparable efficacy, and had an incidence of minimal side effects.

MTV Rehabs – Welcome Viewers to another exciting episode of MTV HABS, the one place on the internet where ou can find addicts doing what they do best. The following footage was taken on site at a drug and alcohol rehabilitation center on the central coast of NSW. The views, actions and opinions are not necessarily correctly represented and do not reflect the rehabilitation center or the people in it. In reality “the glen” has saved many peoples lives as it did with mine.
