Prevalence and importance of polymorphism occurring in pharmaceutical compounds are well recognized. It is of great importance to prepare and select the right form from the beginning during drug discovery and development. This review introduces the basic concepts of “What is polymorphism?”, addresses a fundamental question of “Why do polymorphs form?”, and provides practical guidelines of “How to prepare polymorphs?” “How to evaluate the relative thermodynamic stability between polymorphs?”, and

Gonococci often infect mucosal surfaces bathed in antibacterial fatty acids (FAs). Resistance of gonococci to FAs and other antibacterial hydrophobic agents has been attributed to the mtrCDE-encoded efflux pump system and a heretofore undefined mechanism. This alternative resistance mechanism has been suggested to mediate gonococcal resistance to long-chained FAs independently of the mtr efflux pump. We have now identified this alternative FA resistance system in gonococci and report that it bea

Spirulina is a microscopic and filamentous cyanobacterium that contains essential amino acids, essential fatty acids, vitamins, minerals and anti-oxidative components. The purpose of this study was to examine effects of spirulina intervention in Korean patients with type 2 diabetes. The subjects were 37 type 2 diabetic patients who visited a diabetic clinic in Seoul and randomly assigned into spirulina (8 g/day) or control group. During the intervention period of 12 weeks, subjects were asked to

Three studies explored whether social power affects the perception of physical properties of objects, testing the hypothesis that the powerless find objects to be heavier than the powerful do. Correlational findings from Study 1 revealed that people with a low personal sense of power perceived loaded boxes to be heavier than people with a high personal sense of power perceived them to be. In Study 2, experimentally manipulated power indicated that participants in the powerless condition judged t

The inhalation of silica particles induces silicosis, an inflammatory and fibrotic lung disease characterized by the early accumulation of macrophages and neutrophils in the airspace and subsequent appearance of silicotic nodules as a result of progressive fibrosis. This study evaluated whether apolipoprotein A1 (ApoA1) protects against ongoing fibrosis and promotes the resolution of established experimental lung silicosis. Crystallized silica was intratracheally administered to 6- to 8-week-old

Objectives: This study was performed to investigate the relationship between job stress and the type of turnover of registered nurses in a university hospital. Methods: A total of 553 registered nurses who left the hospital between 1994 and 2005 were surveyed, and aninterview record and self-administered questionnaire completed at the time of the turnover were used to assess the relationship. Job stress was categorized into four sub-scales (factor Ⅰ: insufficient work authority and lack of auton
