The effectiveness of anticancer therapies relies on the ability of these substances to selectively eliminate the malignant cells with little or no toxicity to normal cells. The isolation in most human tumors of a rare subpopulation of cancer stem cells (CSCs) associated with chemo resistance leads to the “stem cell theory” (SCT). The SCT proposed that eliminating this fraction will eventually cure cancer but experimental data supportin Read More

Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder affecting women in reproductive age. Although the etiology of PCOS remains unclear, it is believed to result from genetic, environmental and behavioral interactions. Women with PCOS have higher lifetime risk for cardiovascular disease (CVR) than healthy women at the same age and tend to display insulin resistance (IR). IR has trad Read More

Inhibition of DPP-IV enzyme has taken centre stage as a validated drug target for type 2 diabetes therapy and as a result of research efforts done towards developing effective DPP-IV inhibitors, the first clinical candidate of this class came in focus in 1998. Thus, from 1998 to 2013, these 16-years have witnessed heightened research activities in the discovery and development of clinically relevant inhibitors of DPP-IV as antidi Read More

In the last decades, the cannabinoid system (comprising synthetic and endogenous cannabinoid agonists and antagonists, their receptors and degrading enzymes) has been shown to induce potent immunomodulatory activities in atherogenesis and acute ischemic complications. Different from the other cannabinoid receptors in which controversial results are reported, the selective activation of the cannabinoid receptor ty Read More

Photodynamic therapy (PDT) is a novel medical technique involving three key components: light, a photosensitizer molecule and molecular oxygen, which are essential to achieve the therapeutic effect. There has been great interest in the use of PDT in the treatment of many cancers and skin disorders. Upon irradiation with light of a specific wavelength, the photosensitizer undergoes several reactions resulting in the productio Read More

Tuberculosis continues to be a deadly infectious disease, mainly due to the existence of persistent bacterial populations that survive drug treatment and obstruct complete eradication of infection. The enzymes GlgE and GlgB, which are involved in the glycan pathway, have recently been identified as promising drug targets for combating persistent bacillus strains. In the glycan pathway, enzymes GlgE, GlgA, and Tre-xyz pr Read More

Intravascular substances invade extracellular spaces in the brain via endothelial cells in the sites without bloodbrain barrier (BBB) and move not only in the cerebrospinal fluid (CSF) but also in the interstitial fluid (ISF) of brain parenchyma adjacent to non-BBB sites. It is likely that CSF drains directly into the blood via arachnoid villi and granulations and also to lymph nodes via subarachnoid spaces in the brain and nasal lymph Read More
