with industrial and economic growth and different material production that humans gained from natural resources for their comfort and walfare, inwardly introduced toxic material and heavy metal entered environment that there created serious problems for themselves and environment. This study accomplished to determine heavy metal concentration (As, Ba, Cd, Hg, Pb, Cr)in water resources and river...
با توجه کمبود اطلاعات درباره جنس Potamogeton در ایران و نیز با توجه به پراکنش گسترده آن در اکوسیستمهای آبی کشور، جمعیت های این جنس در اکوسیستم های مختلف اصفهان و چهار محال و بختیاری در طول رودخانه زاینده رود از نظر ریخت شناسی مورد بررسی قرارگرفت، برای این منظور نمونه برداری از 19 جمعیت این جنس انجام گرفت. در طی این مطالعه 6 گونهی ,P. nodosus pusillus, P. perfoliatus, P. pectinatus, P. lucen...
BACKGROUND Despite an increase in the prevalence of medial ulnar collateral ligament (UCL) reconstruction of the elbow in professional baseball and popularity within the media, there are no population-based studies examining the incidence of UCL reconstruction. PURPOSE To examine the epidemiological trends of UCL reconstruction on a statewide level over a 10-year period. The primary endpoint ...
BACKGROUND The majority of children with cow's milk and hen's egg allergy develop clinical tolerance with time. However, there are no good indices to predict when and in whom this occurs. OBJECTIVE The aim of this study was to determine if monitoring food specific IgE levels over time could be used as a predictor for determining when patients develop clinical tolerance. METHODS Eighty-eight...
BACKGROUND Malaria-endemic countries are encouraged to increase, expedite, and standardize care based on parasite diagnosis and treat confirmed malaria using oral artemisinin-based combination therapy (ACT) or rectal artesunate plus referral when patients are unable to take oral medication. METHODS In 172 villages in 3 African countries, trained community health workers (CHWs) assessed and ...
منحنی های کمّیت به شدت (q/i) و پارامترهای مشتق از آنها اطلاعات مفیدی را در خصوص قابلیت استفاده پتاسیم فراهم می کنند. تحقیق حاضر برای تعیین پارامترهای کمیت به شدت پتاسیم شامل پتاسیم آسان قابل تبادل (ko? )، نسبت فعالیت تعادلی پتاسیم ( arek)، پتاسیم به سختی قابل تبادل (kx)، پتانسیل ظرفیت بافری پتاسیم ( pbck) و انرژی تبادل پتاسیم ( ek) و روابط موجود بین آنها با شکل های پتاسیم، کانی های رس خاک و خصوص...
BACKGROUND AND OBJECTIVE Since limited data concerning quantitative and qualitative differences of CD34+ cells collected after different mobilization schedules are available, we investigated phenotype, proliferative capacity and primitive progenitor cell content of CD34+ cells mobilized with four different regimens. DESIGN AND METHODS The number, phenotype, and progenitor cell content of CD34...
Cost-effective and efficacious approaches to the management of hepatocellular carcinoma (HCC) must be developed in response to the rising incidence of this disease worldwide. While surgical resection is the current standard of care, most patients afflicted with HCC are unresectable at diagnosis. Developing good therapy for these patients is thus imperative. Liver transplantation offers the poss...
BACKGROUND Repetitive tensile stresses from valgus torque can induce elbow injury in adolescent baseball players. Insufficient hip range of motion (ROM) can change throwing mechanics, reducing the transfer of energy from the lower to the upper extremities. Thus, hip ROM limitations may force the upper extremities to bear the burden of a strong throw. Improper pitching mechanics caused by insuff...
