The use of formaldehyde and formaldehyde releasers in hairstraightening formulations started in Rio de Janeiro in 2003. The technique is known as BKT, Brazilian keratin treatment. The aim of this study was to analyze the types of skin reactions presented by patients due to BKT. We describe 7 patients with severe erythema and scurf on the scalp which developed shortly after BKT. The lesions were...
Let B be a point robot moving in the plane, whose path is constrained to have curvature at most 1, and let P be a convex polygon with n vertices. We study the collision-free, optimal path-planning problem forB moving between two configurations insideP (a configuration specifies both a location and a direction of travel). We present an O(n2 log n) time algorithm for determining whether a collisi...
Heterotrimeric G proteins interact with G protein-coupled receptors in response to stimulation by hormones, neurotransmitters, chemokines, and sensory signals to intracellular signaling cascades. Recently reported studies indicate that G protein subunits play a significant role in different eukaryotic diseases including inflammation, neurological diseases, cardiovascular diseases, endocrine dis...
This study was conducted to evaluate whether preoperative magnetic resonance imaging (MRI) measurements of the cross-sectional area and length of the semitendinosus tendon correlated with graft diameter. The goal of the study was to identify tendons at risk for requiring graft augmentation. The records of 140 consecutive patients undergoing anterior cruciate ligament (ACL) reconstruction betwee...
PURPOSE Surgical removal of impacted third molars may be the most frequent procedure in oral surgery. Damage to the inferior alveolar nerve (IAN) is a typical complication of the procedure, with incidence rates reported at 1% to 22%. The aim of this study was to identify factors that lead to a higher risk of IAN impairment after surgery. MATERIALS AND METHODS In total 515 surgical third molar...
Solidi cation of a pure material from its undercooled melt is considered, taking into account e ects of surface tension, kinetic undercooling and anisotropy. The resulting crystals exhibit complicated dendritic shapes. To avoid explicit tracking of the solid-liquid interfaces a phase eld model is employed. A di use interface of arti cial width is introduced and the solidi cation is modeled by a...
مقدمه: بتائین (تری متیل گلیسین) به عنوان دهنده گروه متیل و آنتی اکسیدان در مطالعات قبلی شناخته شده است. هدف از انجام این مطالعه بررسی اثرات آنتی اکسیدانی بتائین در آسیب های معدی ناشی از اندومتاسین بود. روش بررسی: در این مطالعه تجربی 32 سر موش بالغ نر از نژاد اسپراگ- داولی به 4 گروه کنترل، اندومتاسین، بتائین-اندومتاسین و آسکوربیک اسید- اندومتاسین به طور مساوی تقسیم شدند. به گروه های کنترل و اندو...
در این تحقیق، ویژگی های کیفی نسبت رطوبت، چروکیدگی، فعالیت آبی، نسبت آب گیری مجدد و شاخص های رنگ گلابی (واریته سردشت) خشک شده به روش ترکیبی اسمزی–اولتراسوند-مایکروویو مورد مطالعه قرار گرفت. مقدار متوسط رطوبت اولیه گلابی ها، 25/79 درصد بر پایه وزن مرطوب بود. غلظت محلول اسمزی (40 و 50 درصد وزنی-وزنی)، دمای محلول اسمزی (30 و 40 درجه سانتی گراد)، زمان اولتراسوند (10 و 20 دقیقه)، توان مایکروویو (20...
We introduce version 2.0 of the Data Structures Library in Java (JDSL). In addition to basic data structures, such as lists and dictionaries, JDSL includes implementations of a variety of complex data structures, such as trees, graphs, and priority queues, with powerful and flexible access to the elements stored, both by means of traditional iterators and by means of new types of accessors call...
Background: There is a growing demand of dialysis in Asia for end-stage renal failure patients. Diabetes mellitus is the leading cause of end-stage renal failure in many countries in Asia. Summary: The growth of peritoneal dialysis (PD) in Asia is significant and seeing a good trend. With the enhanced practices of PD, the quality of care in PD in Asia is also improved. Overall, PD and hemodialy...
