BACKGROUND An effective tool in analysing the learning environment, customised to the Sri Lankan setting, is vital for the assessment and delivery of quality healthcare training of preregistration house officers. Such a tool should be reliable and valid. We assessed psychometric properties such as internal reliability and construct validity of a modified version of the Postgraduate Hospital Edu...

Background:Addiction is regarded as one of the most important social issues influencing all aspects of people’s lives including personal, social, physical, and mental aspects. Given the increasing rate of the disease and its associated irreparable damages to a patient’s life and the community, this disease and its methods of preventing and treating should especially be taken into consideration....

Hydrology helps determine the character of wetlands; wetlands, in turn, regulate water flow, which influences regional hydrology. To understand these dynamics, we studied the Naoli basin where, from 1954 to 2005, intensive marshland cultivation took place, and the watershed's wetland area declined from 94.4 × 10(4)ha to 17.8 × 10(4)ha. More than 80% of the wetland area loss was due to conversio...

OBJECTIVE Genetic imaging is used to investigate the mechanism by which genetic variants influence brain structure. In a previous study, a structural change of the dorsolateral prefrontal cortex was associated with symptom modulation in post-traumatic stress disorder patients. This study examined the effect of a polymorphism in the gene encoding brain-derived neurotrophic factor (BDNF) on regio...

Expression of the gene encoding the halobacterial photoreceptor sensory rhodopsin I (SRI), sopI, was studied by means of homologous gene targeting. A sopI- Halobacterium salinarium mutant strain was constructed by homologous replacement of sopI with a novobiocin-resistant gyrB from Haloferax Aa 2.2. Cells bearing gyrB were resistant to novobiocin, indicating that the Haloferax gene is functiona...

Emotion regulation strategies are considered as determinant variables on both normal and psychopathological processes. The aim of the present study was to investigate the mediating role of emotion regulation difficulties on the relationship between social anxiety symptoms and anger. A total of 171 participants (71 men, 100 women) from the city of Tehran participated in this study as volunteers....
