Natural Vibrio cholerae infection generates a robust B-cell response that wanes for T-cell independent antigens, suggesting that B-cell responses may be mediated in a T-cell dependent manner. Patients with cholera develop a memory-effector T-cell response to cholera antigens, and B-cell activation occurs after T-cell population expansion, suggesting that T-cells may play an important role in the development and maintenance of memory B-cell responses to T-cell dependent antigens.

We describe a novel platform, the nCounter Analysis System, for sensitive, highly multiplexed, digital gene expression analysis based on NanoString’s novel molecular barcoding technology. Detection of individual mRNA molecules using an assigned sequence of six different fluorescent spots per probe are detected, and then the number of times that code sequence appears in a sample are counted.

The study aims to design antigomirs against miRNAs involved in Cardiomyopathy. Potential miRNAs involved in the down regulation of certain important genes during this disorder have been identified. All reported miRNAs were scanned using an algorithm against these genes. At three step protocol was followed to take care of false positives and false negatives. Further, HL-1 cells (cardiomyocytes) are been transfected by anti-miRNAs for confirmation.

Constitutive TNF-alpha expression is characteristic of the malignant ovarian surface epithelium. Adenoviral mutants hold great promise as gene therapy vectors but their efficacy is hindered by an inflammatory cascade orchestrated by TNF-alpha. We found that delivering TNF-alpha shRNA to ovarian cancer cells using oncolytic adenoviruses could reduce the inflammatory cascade generated by adenoviruses and also had direct anti-tumour activity on the cancer cells.

Systemic delivery of both small molecules and macromolecules via inhaled therapies is an area of significant ongoing research1. The pulmonary route offers the physiological benefits of a highly vascularised, large surface area for absorption which can promote high bioavailability and a rapid onset of action. For biomolecules such as peptides, proteins and nucleic acid derivatives, inhaled drug delivery can also provide a viable alterative to intravenous administration.

Many drug classes are known to alter the rate of gastric emptying. Whilst there is no specific regulatory guidance requiring the impact of drugs on GE to be measured, it is important to fully understand the mode of action and the relationship between the pharmacokinetic profile and the pharmacodynamic response.

The transition of a drug candidate into Phase I and other early drug development programs is undergoing considerable examination and change. This has largely been brought about by commercial and scientific drivers to reduce attrition rates coupled with an evolving regulatory environment, all of which encourage the pharmaceutical industry to build both scientific focus and flexibility into the drug development program.

Many modified release (MR) oral formulations rely on bioavailability from the distal regions of the gastrointestinal (GI) tract (i.e. the ileum and colon). Therefore, by assessing the bioavailability of a drug following delivery to the distal intestines, it is possible to determine whether MR formulation development is achievable.

We synthesized fourteen 6-oxa-8a-estrogens analogues and investigated osteoprotective and uterotropic actions. We demonstrated correlation: every modification in structure of 6-oxa-8-analogues leading to strong (>30%) reduction of uterotropic action induces slump of osteoprotective activity. This allows to make conclusion: main biotarget, responsible for appearance of osteoprotective action is a-estrogen receptor. We found steroid estrogen analogues with cholesterol-lowering properties without u
