BACKGROUND Migraine is a prevalent neurological disorder with a complex genetic background characterized by recurrent episodes of headache. The disease is subclassified into migraine with aura (MA) and migraine without aura (MO). Many association studies have been performed to date to identify genetic risk variants for common migraine, most of them focusing on selected candidate genes, with var...

فاصله بین سقوط ایلخانان (736 ق) تا روی کار آمدن صفویان (907 ق) از پرآشوب­ترین و آشفته­ترین دوره­های تاریخ ایران است که عرصه را برای نضج و قدرت­گیری حکومت­های مختلفی در گوشه و کنار ایران فراهم آورد. جغرافیای سیاسی قبایل کُرد در غرب و شمال غرب که صحنه قدرت­نمایی آل جلایر، تیموریان، قراقویونلوها و آق قویونلوها بود از جمله حوزه­های موردتوجه و فعالیت حکومت­های مورد اشاره بود. پژوهش حاضر درصدد پژوهش د...

It remains unclear if differences in bone mineral density (BMD) exist at different skeletal sites between people with schizophrenia and age- and sex-matched healthy controls (HCs). Major databases were searched from inception until February 2016 for studies measuring BMD using dual-energy X-ray absorptiometry (DXA) at any skeletal site in individuals with schizophrenia. Ten studies investigatin...

14C-labelled proteins from E. coli 30S ribosomal subunits were isolated by HPLC, and selected groups of these proteins were reconstituted with 32P-labelled 16S RNA. The isolated reconstituted particles were partially digested with ribonuclease A, and the RNA fragments protected by the proteins were separated by gel electrophoresis and subjected to sequence analysis. Protein S7 alone gave no pro...

In order to identify the demographic features, seizure types and epilepsies, we reviewed the files of 1379 patients admitted to the epilepsy outpatient clinic of Bakirköy State Hospital for Neurological and Psychiatric Diseases between 1991 and 1994. Of these, 160 patients' files contained inadequate information and 80 patients with nonepileptic events were excluded from the study. There were 5...

Although subsequent studies have provided extensive support for the 1968 Tiffany and Krimm proposal (Biopolymers 6, 1379) that the polyproline II (PPII) conformation is a significant component of the structure of unordered polypeptide chains, two issues are still not fully resolved: the PPII persistence length in a chain and the source of its relative stability with respect to the β-conformatio...

The Traveling Salesman Problem (TSP) is an NP-hard problem that has been used as a significant testing ground for many algorithms. It is also a problem that appears in many real industrial problems. This paper describes a Bee Colony Optimization (BCO) algorithm with a fragmentation state transition rule (FSTR) for TSP. The FSTR in the BCO algorithm helps bees to produce a tour by combining a fe...
