BACKGROUND: Although functional tests including the single leg hop (SLH), triple hop (TH), cross over hop (COH) for distance, and the tuck jump assessment (TJA) are used for return to play (RTP) criteria for post anterior cruciate ligament (ACL) injury, sport-specific baseline measurements are limited. PURPOSE: The purpose of this study was to examine differences in SLH, TH, and COH distance and limb symmetry index (LSI), as well as total scores, number of jumps, and individual flaws of the TJA in 97 injury-free Division I (DI) collegiate female student athletes participating in ACL injury prone vs...

Return-to-play (RTP) decisions often represent a challenge to physicians caring for athletes. The multifaceted and unique nature of each RTP decision makes standardization of the decision-making process impossible and demands of the physician thoughtful consideration of all competing interests and variables. Such difficult medical decisions are further complicated by unique ethical and legal considerations. Although no concrete RTP recommendations are available, the consensus of experienced team physicians and knowledge of the rules and regulations that apply to RTP are helpful guides to treating the various upper extremity injuries that occur in elite athletes...

The design and preparation of metal-free organic materials that exhibit room-temperature phosphorescence (RTP) is a very attractive topic owing to potential applications in organic optoelectronic devices. Herein, we present a facile approach to efficient and long-lived organic RTP involving the doping of N-phenylnaphthalen-2-amine (PNA) or its derivatives into a crystalline 4,4'-dibromobiphenyl (DBBP) matrix. The resulting materials showed strong and persistent RTP emission with a quantum efficiency of approximately 20 % and a lifetime of a few to more than 100 milliseconds...

Study Design Survey. Objective Sports-related spinal cord injury (SCI) represents a growing proportion of total SCIs but lacks evidence or guidelines to guide clinical decision-making on return to play (RTP). Our objective is to offer the treating physician a consensus analysis of expert opinion regarding RTP that can be incorporated with the unique factors of a case for clinical decision-making. Methods Ten common clinical scenarios involving neurapraxia and stenosis, atlantoaxial injury, subaxial injury, and general cervical spine injury were presented to 25 spine surgeons from level 1 trauma centers for whom spine trauma is a significant component of their practice...

Muscle injuries are frequent and represent one of the most substantial medical problems in professional football. They can have both traumatic and overuse causes with direct practical consequence due to differences in terms of the post-primary care regimen and prognosis. An accurate diagnosis is the first step towards a specific treatment and usually allows to predict return to play (RTP). Current treatment principles have no firm scientific basis; they are practiced largely as empirical medicine due to a lack of prospective randomised studies...

There is worldwide concern with regard to the adverse effects of drug usage. However, contaminants can gain entry into a drug manufacturing process stream from several sources such as personnel, poor facility design, incoming ventilation air, machinery and other equipment for production, etc. In this validation study, we aimed to determine the impact and evaluate the contamination control in the preparation areas of the rapid transfer port (RTP) chamber during the pharmaceutical manufacturing processes. The RTP chamber is normally tested for airflow velocity, particle counts, pressure decay of leakage, and sterility...

BACKGROUND: Shoulder instability in athletics is a common occurrence. However, there is controversy as to whether non-operative versus operative management is the most effective treatment in youth athletes. We systematically reviewed recurrence and return to play (RTP) after shoulder instability events in youth athletes based on surgical versus non-surgical intervention. DESIGN: The systematic review concerned studies published before August 2016. Statistical analysis was performed to compare rates of recurrence for each extracted risk factor...

PURPOSE: Malnutrition is one of the important risk factors for postoperative complications. Transferrin, prealbumin, and retinol-binding protein, so-called rapid turnover proteins (RTPs), may be the better indicators for early detection of nutritional deficits. However, few studies have described the impact of serum RTP levels on postoperative surgical site infection (SSI) in spine surgery. The purpose of this study was to investigate the relationship between preoperative serum RTPs and postoperative SSI...

: We report an in vitro RNA synthesis assay for the RNA dependent RNA polymerase (RdRP) of rabies virus (RABV). We expressed RABV large polymerase protein (L) in insect cells from a recombinant baculovirus vector and the phosphoprotein cofactor (P) in Escherichia coli and purified the resulting proteins by affinity and size exclusion chromatography. Using chemically synthesized short RNA corresponding to the first 19-nt of the rabies virus genome we demonstrate that L alone initiates synthesis on naked RNA, and that P serves to enhance initiation and processivity of the RdRP...

BACKGROUND: Vestibular and ocular motor impairments are routinely reported in patients with sports-related concussion (SRC) and may result in delayed return to play (RTP). The Vestibular/Ocular Motor Screening (VOMS) assessment has been shown to be consistent and sensitive in identifying concussion when used as part of a comprehensive examination. To what extent these impairments or symptoms are associated with length of recovery is unknown. PURPOSE: To examine whether symptom provocation or clinical abnormality in specific domains of the VOMS results in protracted recovery (time from SRC to commencement of RTP protocol)...

The authors examined the efficacy of an 8-week regimen combining repetitive task-specific practice (RTP) with a myoelectric brace (RTP+Myomo) on paretic upper extremity (UE; use in valued activities, perceived recovery, and reaching kinematics) in 12 subjects (4 men; M age = 53.5 years; mean time poststroke = 61.7 months). Seven subjects were administered RTP+Myomo therapy, and 5 were administered RTP only. Both groups participated in individualized, 45-min therapy sessions occurring 3 days/week over an 8-week period...

A mechanism for the enhanced room-temperature phosphorescence (RTP) of gadolinium-coordinated hematoporphyrin monomethyl ether (Gd-HMME) in the presence of imidazole and free gadolinium ions (Gd(3+)) is revealed. Imidazole, the molten solvent used in the synthesis of Gd-HMME, was effective in enhancing the Gd-HMME RTP. In the presence of imidazole, further enhancement of the Gd-HMME RTP was observed upon adding Gd(3+). Overall, a 40-fold enhancement of Gd-HMME RTP intensity was achieved by adding both imidazole and Gd(3+)...

An intra-cavity RbTiOPO4 (RTP) cascade Raman laser was demonstrated for efficient multi-order Stokes emission. An acousto-optic Q-switched Nd:YAlO3 laser at 1.08 μm was used as the pump source and a 20-mm-long x-cut RTP crystal was used as the Raman medium to meet the X(Z,Z)X Raman configuration. Multi-order Stokes with multiple Raman shifts (~271, ~559 and ~687 cm(-1)) were achieved in the output. Under an incident pump power of 9.5 W, a total average output power of 580 mW with a pulse repetition frequency of 10 kHz was obtained...
