The acknowledgement of risks for traumatic brain injury in American football players has prompted studies sideline concussion diagnosis and testing neurological deficits. While concussions are recognized etiological factors a spectrum sequelae, the consequences sub-concussive events unclear. We tested hypothesis that blood-brain barrier disruption (BBBD) accompanying surge astrocytic protein S100B blood may cause an immune response associated with production auto-antibodies. also wished to...

Abstract Based on the accumulating evidence of osteogenic cells present in systemic circulation, we hypothesized that circulating connective tissue progenitors (CTPs) home to fracture site and contribute skeletal repair. Parabiotic animals were formed by surgically conjoining transgenic mice constitutively expressing green fluorescent protein (GFP) no erythroid syngeneic wild‐type mice. After 3 weeks parabionts, equilibrium blood chimerism between partners was established. A transverse...

Abstract Background Concurrent chemoradiation therapy has been demonstrated to be effective as an organ‐sparing treatment for select advanced head and neck squamous cell carcinoma (HNSCC). However, this modality is not without side effects. One effect the formation of upper esophageal strictures. As concurrent used more frequently, it important identify risk factors associated with stricture formation. Methods A retrospective chart review all patients who had undergone definitive between...

The objective of this study was to determine whether meditation affects pain and quality life in people with multiple sclerosis (MS) peripheral neuropathy (PN). A total 22 patients (10 MS, 12 PN) participated a weekly class over 2-month period. 18 controls (7 11 received standard care. Primary outcome assessments were based on the 36-item Short Form Health Status Survey (SF-36) visual analogue scale (VAS) for at baseline 2 months. Secondary measures included Neuropathy Impairment Score (NIS)...

Background: The bony architecture of the hip depends upon functional adaptation to mechanical usage via dynamic interaction between acetabulum and femoral head. Acetabular retroversion is thought be a contributing factor pincer-type femoroacetabular impingement. Studies pathological joints suggest proximal anatomy compensates for acetabular retroversion. Hypothesis/Purpose: purpose this study was determine if predictable relationship exists angles, age, gender in normal joints. We...

To compare the biological effects of riboflavin-ultraviolet A (UVA) corneal cross-linking (CXL) performed with a traditional epithelium-off method to several transepithelial methods in rabbit model. Preliminary experiments on biomechanical rigidity were also performed.Four treatment groups included: (1) standard epithelium-off, (2) tetracaine transepithelial, (3) benzal-konium chloride-ethylenediaminetetraacetic acid (BKC-EDTA) and (4) femtosecond laser-assisted riboflavin-UVA CXL.

A dual childbirth injury model, including vaginal distension (VD) and pudendal nerve crush (PNC), may best represent the injuries seen clinically. The objective of this study was to investigate urethral function, anatomy, neurotrophin expression after several simulated injuries. Groups 140 rats underwent PNC, VD, PNC+VD, or neither (C). Four days injury, all groups had significantly decreased leak-point pressure (LPP) compared with C rats. Ten LPP in PNC PNC+VD remained lower than Three...
