Multiple sclerosis (MS), the most common disabling neurologic disease of young people, afflicts approximately a quarter of a million Americans. The symptoms of MS result from recurrent attacks of inflammation in the central nervous system, which probably occur through an autoimmune mechanism. The target of the immune attack is myelin, the lipoprotein sheath that surrounds the axons and insulate...

This research builds on the emerging body of literature investigating implications changing land tenure relations in Prairie Provinces, where over 70% Canada’s farmland is located. Through an analysis survey data collected 2019 from 400 grain farmers, we address following questions: How are farmers experiencing patterns and control at local level? What challenges opportunities do face these mar...

  Purpose: Scabies is a parasitic disease with nocturnal itching and cutaneous lesions. It spreads   by physical contact and it occurs mostly in crowded places. Because of their occupation, military   personnel have to live in garrisons and camps. So the prevalence of scabies is higher in military   systems. Hence, this study evaluated the epidemiology of scabies in Iran’s Army.   Materials and...

Calomyscus elburzensis Goodwin, 1938, was previously known from central and northern Iran to southern and southwestern Turkmenistan and northwestern Afghanistan. Its type locality is at altitude of 1200m elevation in the Kurkhud Mts., North Khorasan province in northeastern Iran. This study provides new evidence that its range is more extensive than thought previously and central Iranian Mounta...

The four stages of postformal thought are Systematic, Metasystematic, Paradigmatic, and Cross-Paradigmatic. Each successive stage is more hierarchically complex than the one that precedes it. Each stage uses the elements formed at the previous stage to construct more hierarchically complex elements (e.g., metasystems, paradigms). An actual instrument constructed using the Model of Hierarchical ...

Sir, Side-e¡ects of drugs are often thought to be the cause of certain skin manifestations, especially in cases of clear time-relationships. We describe here a patient in whom side-e¡ects of antihypertensive drugs were suspected, but since the speci¢c combination of telangiectasia of the cheeks and gingival hyperplasia had not been described previously some delay occurred before it was clear th...

We investigated the circumstances of unintended carbon monoxide deaths from motor vehicle exhaust. Of 64 episodes involving 82 deaths investigated by the West Virginia Office of the Chief Medical Examiner, 1978-84, 50 occurred outdoors in older vehicles with defective exhaust systems and 14 occurred in enclosed or semi-enclosed home garages. Blood alcohol was detected in 50 (68 per cent) of 74 ...

After a 75-year absence from Florida, substantial local transmission of dengue virus (DENV) occurred in Key West, Monroe County, Florida in 2009 and continued in 2010. The outbreak culminated in 85 reported cases. In 2011 and 2012, only isolated cases of local DENV transmission were reported in Florida, none were reported in Key West. In 2013, a new outbreak occurred, but this time in Martin Co...

Upstream of Byrd Station (West Antarctica), ice-penetrating radar data reveal a distinctive fold structure within the ice, in which isochronous layers are unusually deep. The fold has an axis more than 50 kilometers long, which is aligned up to 45 degrees to the ice flow direction. Although explanations for the fold's formation under the present flow are problematic, it can be explained if flow...
