Background Intra-articular injuries to the hip in elite athletes represent a source of significant pain and disability. Hip arthroscopic surgery has become the gold standard for the treatment of disorders involving the hip joint. Purpose To examine the incidence of and abnormalities treated with hip arthroscopic surgery as well as the impact on future participation in American football athlet...

Background: We compared the wave amplitude of visually evoked potential (VEP) between patients with esotropic and anisometropic amblyopic eyes and a normal group.Methods: The wave amplitude of VEP was documented in 2 groups of persons with amblyopia (15 with esotropia and 28 with anisometropia) and 1 group of individuals with normal visual acuity (n, 15). The amplitude of P100 was recorded mono...

BACKGROUND Anterior cruciate ligament (ACL) injuries are common in the National Football League (NFL). Limited literature exists regarding return to play (RTP) and the factors affecting RTP after ACL reconstruction in NFL players. PURPOSE/HYPOTHESIS To determine RTP rates after ACL reconstruction in NFL players and to ascertain which variables affect RTP in these players. We hypothesized that...

OBJECTIVE We assessed CSF levels of the light chain subunit of neurofilaments (NfL) at baseline and after fingolimod therapy or placebo in patients with relapsing-remitting multiple sclerosis (RRMS). Changes in NfL levels were also correlated with relapse and MRI outcomes. METHODS CSF samples were available, at baseline and 12 months after treatment initiation, from a subset of 36 patients wi...

The No Free Lunch (NFL) theorem due to Wolpert and Macready (1997) has led to controversial discussions on the usefulness of randomized search heuristics, in particular, evolutionary algorithms. Here a short and simple proof of the NFL theorem is given to show its elementary character. Moreover, the proof method leads to a generalization of the NFL theorem. Afterwards, realistic complexity theo...

tions that may result in disfigurement and functional impairment. Other manifestations of the syndrome include neuroendocrine tumors of the duodenum (somatostationomas) and pheochromocytomas. Numerous mapping studies localized the NFl gene on the long arm of chromosome 17 near the centromere and led to cloning of the complete coding region (13). The NFl gene encodes an mRNA of 11-13 kb containi...

BACKGROUND Navicular injuries can result in persistent pain, posttraumatic osteoarthritis, and diminished performance and function. PURPOSE To determine the epidemiology of navicular fracture in players participating in the National Football League (NFL) Scouting Combine and evaluate the impact of a navicular injury on the NFL draft position and NFL game play compared with matched controls. ...

BACKGROUND Frontotemporal dementia (FTD) is recognised as a clinically and morphologically heterogeneous group of interrelated neurodegenerative conditions. One of the subtypes within this disease spectrum is the behavioural variant FTD (bvFTD). This is known to be a varied disorder with a mixture of tau-positive and tau-negative underlying pathologies. The other subtypes include semantic demen...

Summary Aim : The purpose of this study is to determine the prevalence of amblyopia in 1310 children less than 10 years old at south east province of Tehran in 1994. Method : Diagnosis of amblyopia is based on linear snellen best corrected vision of 8/10 or less and or difference of 2 lines between eyes in children over 3 years old and behavioral difference when one eye is covered as compared...

purpose : to determine the prevalence of amblyopia and strabismus in the schoolchildren of the city of bojnourd, iran methods : in 2010, randomized stratified cluster sampling was employed in a cross-sectional study on primary and junior high schoolchildren. all the examinations were performed in schools. all students received refraction, vision and subjective refraction tests. the cover test w...
