dog rose (rosa canina l.) is a wild native species in iran, with a significant genetic diversity. the purpose of this research was to study quantitative and qualitative characteristics of saturated and unsaturated fatty acids dog rose ecotypes in five habitats of isfahan province in 2014-2015. oil was extracted from seeds by using soxhlet apparatus; the fatty acid composition of oil was charact...

Bulbar urethral ischemic necrosis (BUIN) is an iatrogenic entity resulting from repeated attempts at performing anastomotic urethroplasty for pelvic fracture injuries. Etiologically speaking, BUIN related to a compromised blood supply of the bulbar urethra, which normally relies on anterograde arteries and retrograde recurrent branches dorsal penile arteries, through glans. At each transection ...

allowing animals to adapt to changing internal and external environments. During development, learning and in ongoing behaviour, individual neurons, synapses and the circuits they form show short-term and long-term changes as a result of experience. Plasticity occurs at all levels, from the behaviour of single ion channels to the morphology of neurons and large circuits and over timescales rang...

October 2005, Vol. 95, No. 10 SAMJ Great strides were made during the last century in the management of diabetes in pregnancy. Before the discovery of insulin in 1921 the outlook for the diabetic mother and her fetus was abysmal. With the advent of insulin, an emphasis on a team approach to care, improved methods of fetal surveillance, and a focus on metabolic normalisation brought about by int...

Cocaine is a widely abused substance with psychostimulant effects that are attributed to inhibition of the dopamine transporter (DAT). We present molecular models for DAT binding of cocaine and cocaine analogs constructed from the high-resolution structure of the bacterial transporter homolog LeuT. Our models suggest that the binding site for cocaine and cocaine analogs is deeply buried between...
