AbstractThe purpose of this study was to screen for mental and behavioral health risk of Division II collegiate student athletes using a novel online screening tool (i.e., Heads Up Checkup) viathe Sharpen mobile platform and learn the practicality of using such a tool. Collegiate student athletes (n = 367) were recruited to complete the Heads Up Checkup mental and behavioral health screening through the Sharpen mobile application. A total of 338 out of 367 possible collegiate student athletes completed the screening for a participation rate of 92.09%. Participants self-reported mental and behavioral health symptoms, including risk and criteria for 26 ICD-10 disorders. Across the sample, 17.1% of participants (n = 63) met at least 50% of the criteria for at least one diagnosis, 18.8% of participants (n = 69) met 70–99% of diagnostic criteria for at least one diagnosis, and 15.5% of participants (n = 57) met 100% of diagnostic criteria for at least one ICD-10 diagnosis. Although the Heads Up Checkup cannot diagnose disorders, it can be a valuable screening tool to assist coaches, trainers, clinicians, and athletic staff to collaboratively care for collegiate student athletes.

There has been a shift in higher education from traditional lecture-based learning to incorporating high-impact practices and experiential learning. These practices offer students an opportunity to engage in real-world settings that allow them to apply course content directly into practice. In order for high-impact practices to be effective, both program implementation and evaluation should be conducted collaboratively with community stakeholders, also known as community-based participatory research (CBPR). The Girls Empowering Movement (GEM) initiative, an out-of-school time physical activity program, is an example of CBPR in that it was developed by middle school girls, for middle school girls. The purpose of this article is to provide the framework used to recruit and train undergraduate students to collaboratively lead the GEM initiative in the southeastern United States. This article discusses how community partnerships were created, how specific content and curricular decisions were made to foster a unique learning experience, and how evaluation protocols were created to ensure undergraduate learning and community collaboration.

Duke (b) Keywords: Manufacturing; Automated systems; Performance/productivity Abstract: Statistical process control by a simple control chart of a process variable is based on the assumption that the process variable is an independent identically distributed random variable. In practice the process variable typically contains significant correlations due to common cause effects. These common cause effects become confounded with special cause effects. The objective of time series model based statistical process control is to separate the process variable into two components, namely the systematic variation due to common cause (contained in the fitted values) and the purely random variation (contained in the residuals). The moving-window spectral (MWS) time series model is a frequency domain approach. It is an extension of the time series concept to a generalized automatic system that further decomposes the process variable into trend, periodic components and residuals. The MWS model is applied to simulated autoregressive process variable series containing multiple periodic components and randomness. The proposed dual chart MWS method outperforms the standard X chart and the time domain exponentially weighted moving average (EWMA) model. The MWS method is the only one to correctly classify and detect special cause and common cause effects for small and large process shifts with no increase in false alarms.

The primary objective was to (a) test the effectiveness of an Exercise Is Medicine® on Campus (EIM-OC) program in a university setting and (b) compare the baseline levels of physical activity, mental health, and physical health with post-EIM-OC levels. Referred and consenting students (n= 9) participated in a 12-week program. At pre- and postprogram, participants completed measures of current health behaviors, obstacles to physical activity, health goals, physical activity history, biometric screening (resting heart rate, blood pressure (BP), waist-to-hip ratio, body composition percentage via bioelectrical impedance, cardiovascular and muscular endurance baseline, and flexibility), perceived stress, and self-compassion. All of the participants adhered to 100% of the program. Participants experienced a decrease in resting heart rate, body composition, and BP and an increase in sleep, physical activity, and self-compassion. The program will be implemented with a larger sample of referred students with the goal of reducing risk or prevalence of chronic disease.

Bertolotti’s syndrome is characterised by anomalous enlargement of the transverse process(es) of the most caudal lumbar vertebra which may articulate or fuse with the sacrum or ilium and cause isolated L4/5 disc disease.We analysed the elective MR scans of the lumbosacral spine of 769 consecutive patients with low back pain taken between July 2003 and November 2004. Of these 568 showed disc degeneration. Bertolotti’s syndrome was present in 35 patients with a mean age of 32.7 years (15 to 60). This was a younger age than that of patients with multiple disc degeneration, single-level disease and isolated disc degeneration at the L4/5 level (p = 0.05). The overall incidence of Bertolotti’s syndrome in our study was 4.6% (35 of 769). It was present in 11.4% (20 patients) of the under-30 age group.Our findings suggest that Bertolotti’s syndrome must form part of a list of differential diagnoses in the investigation of low back pain in young people.

Designing for continuous interaction requires designers to consider the way in which human users can perceive and evaluate an artefact’s observable behaviour, in order to make inferences about its state, and plan and execute their own continuous behaviour. Understanding the human point of view in continuous interaction requires an understanding of human causal reasoning, of the way in which humans perceive and structure the world, and of human cognition. We present a framework for representing human cognition, and show briefly how it relates to the analysis of structure in continuous interaction, and the ways in which it may be applied in design.

Background:: Many modalities for the treatment of tattoos and pigmented lesions produce a greater risk of complications in Fitzpatrick types V and VI skin because of an increased incidence of adverse pigmentary changes and keloidal scarring. In fair-skinned persons, Q-switched lasers have proved effective in removing pigmented lesions and tattoos without scarring. Objective:: This study was conducted to determine the efficacy and effects of Q-switched lasers on a small series of darkly pigmented patients with tattoos. Methods:: Four patients of Ethiopian origin with facial and neck tribal tattoos were treated with both the Q-switched ruby and Nd:YAG lasers. One black woman with a multicolored tattoo on the mid chest was treated with the Q-switched ruby laser. Results:: Clearing of all lesions was seen. The treatments did not result in scarring or permanent pigment changes other than the ones intended. Conclusion:: Our results indicate that in darkly pigmented patients, Q-switched laser treatment of tattoos can be performed successfully. The longer wavelength Q-switched Nd:YAG laser is recommended when removing tattoos in darker complected persons. A test treatment is advised before treatment of large skin areas.

The athymic nude rat rnu/rnu has been established as an in vivo model for the acceptance of human digestive-tumour xenografts. We report the successful xenografting of 7/12 (58%) primary explants from patients with digestive cancer. Successful xenografting also occurred in 21/25 (84%) pancreatic tumours derived from a pancreatic exocrine adenocarcinoma (GER) maintained in cell culture, 2 of those have been successfully passaged in nude rats. The simultaneous implantation of these tumours into nude mice led to an almost identical take rate. Passage of one colonic and one pancreatic xenograft from nude rats into nude mice, and transplantation back into nude rats, increased the take rates. The critical period for the establishment of primary tumour growth was usually 28-42 days. The xenografts maintained histological and cytological characteristics of the primary explants or of the original tumour from which the cell line derived. The karyotype of the cell line was also maintained in the solid tumour. Three murine tumours were successfully grown as xenografts. Despite their immunoincompetence, the rats in this study showed no increased morbidity or mortality when kept in conventional conditions, compared with animals housed in isolators. The athymic nude rat will become a valuable complementary tool to the nude mouse for the establishment and maintenance of human digestive tumours and for surgical and serial serological studies.

Homozygous nude rats (rnu/rnu) injected s.c. with 3 X 10(7) human pancreatic cancer cells from the GER cell line developed circulating antibody to GER cell surface, detected in a 125I binding assay against viable GER cells in vitro. Antibody titre rose with progressive xenograft growth. These antibodies showed no selectivity for GER cells when compared with a panel of other human cell lines. Heterozygous nude rats (rnu/+) immunised with serum from their GER xenograft-bearing nude relatives (rnu/rnu) also developed anti-GER cell surface antibodies. These antibodies showed some selectivity for GER and WAD (a second human pancreatic cancer cell line) when compared with other human cancer cells and lymphocytes. These findings show that some human pancreatic cancer cell surface components may persist independently in the circulation of xenograft bearing rnu/rnu rats despite the presence of antibody excess to other surface determinants from the same cells. It is suggested that differences in the relative immune competence of rnu/rnu and rnu/+ rats may offer a biological opportunity for enhancing the recognition of weak antigenic determinants which may have some useful selectivity for different types of human tumour cells.

Antibodies directed against the antigen released from viable tumour cells during growth have been raised by cross-immunization of immunocompetent hairy litter-mates with serum from nude mice bearing pancreatic tumour xenografts. Antisera raised against the components released from a primary pancreatic tumour xenograft (WB) or from a tumour cell-line xenograft (GER) showed a titre greater than 1:625 against cultured pancreatic tumour cells by an I125-binding assay. Five out of 14 of the hairy litter-mates immunized with serum from the same tumour (GER) produced antisera that bound more strongly to pancreatic cancer cells than to 13 other non-pancreatic cell lines (binding ratio greater than 2). Absorption of the antisera with pure CEA reduced the level of binding by 11-25% without affecting the specificity for pancreatic tumour cells. The antibody response could be completely removed by absorption with pancreatic tumour cells, whereas 50% and 18% of the activity remained after absorption with normal pancreas homogenate and a mixed non-pancreatic tumour-cell pool, respectively. Immunofluorescent staining of pancreatic tumour sections indicated that the antibody was localized on the membrane of ductular epithelial cells. Challenge of immunocompetent mice using this procedure has produced a polyspecific antiserum with signs of selectivity for the circulating antigens released from pancreatic cancer cells, and may provide a route to the production of antibody against specific tumour components.

Primary human panceratic exocrine adenocarcinoma has been established in tissue culture and as xenografts in immune-deficient nu/nu mice. The cell line has a doubling time of 36 h and grows as a confluent monolayer together with a constant population of free-floating cells. Evidence of tumourigenicity was provided by growth on an early diploid fibroblast monolayer and in soft agar, and as solid tumours in immune-deficient nu/mu mice. Chromosome analysis of the cultured cells confirmed their tumour origin. Xenografts established from the cell line or directly from primary tumour tissue have retained a similar histology to the original tumour on serial transplantation. An electrophoretic study of exportable pancreatic digestive enzymes and a number of intracellular enzymes has shown that the cell line and xenografts maintain a human intracellular enzyme profile, but do not produce pancreatic digestive enzymes.

Glass-ceramic materials may transmit visible light if either of the following conditions are operative: (i) the crystallites of all species are much smaller than the wavelength of visible light, or (ii) the optical anisotropy (birefringence) within the crystals and refractive index difference between crystals and glass are very small. These conditions are achieved in several aluminosilicate glass-ceramic systems. Solid solutions (ss) of ß-quartz, spinel, and mullite are the major crystalline phases in these transparent glass-ceramics. The transparent ß-quartz solid solution glass-ceramics can be divided into three areas: ultra-low expansion materials, refractory and colourless materials, and high electrical resistivity—low dielectric loss materials. These three material groups, though chemically distinct, are all characterised by high crystallinity, thermal shock resistance, excellent chemical durability, and susceptibility to mechanical strengthening by ion-exchange techniques.

The symptoms, diagnostic categories, and general characteristics of patients in 70 cases of adverse reactions to lysergic acid diethylamide tartrate (LSD) are varied. Psychiatric side effects ranged from depressive reaction to psychotic states. In all cases, LSD ingestion occurred separately and apart from medical-experimental and psychiatric-therapeutic models of LSD usage. Findings based on these cases and from observations made on LSD users in the community indicate that widespread use of LSD is a cause for concern.

Titania- and zirconia-nucleated glasses in the basic Li_2Al_2O_4–SiO_2 system were found suitable for casting relatively large mirror blanks. Upon heat treatment, these glasses crystallized uniformly to yield transparent, very low expansion β quartz solid solution glass-ceramics. Special care was required in processing large diameter blanks, owing to localized temperature increases resulting from the exothermic heat of crystallization. Glass-ceramics with a wide range of β quartz solid solution stability resulted in a uniform product. Transparent glass-ceramic mirror blanks were obtained with average expansion coefficients from 5°C to 50°C of 0 ± 0.3 × 10^−7/°C. Ware up to 15 cm thick was processed to less than 10 mμ/cm strain, with no change in expansion or transparency through the blank. Work with thick ware provided additional insight into the problems that might be encountered in the fabrication of very large castings.

Physical property measurements are reported for beryl glass and for three 60 mole % SiO2 melts (including beryl) at temperatures above 1600° C. Electron micrographic evidence shows that beryl glass has undergone a two-liquid phase separation. Density measurements of this glass and its melt can be interpreted in terms of the dissociation of Si6O18-12 rings as beryl melts incongruently. The presence of discrete BeO4 tetrahedra and AlO6 octahedra in molten beryl is suggested by the electrical conductance and viscosity data for these melts.

The effect of hormone therapy on the growth of human non-endocrine pancreatic adenocarcinoma xenografts in nude mice was evaluated. The androgen testosterone stimulated tumour growth rate, whereas the anti-androgen cyproterone acetate significantly inhibited tumour growth rate compared with untreated controls. These findings provide further support for the suggestion that the growth and metabolism of pancreatic carcinoma may be dependent on the sex steroid hormones.

The Gaussian surrogate-date procedure was applied to the measurement of the effect of cigarette smoking on the dimensional complexity of normal, resting EEG. Evidence of significant nonlinearity in the EEG was obtained, replicating previous results. However, unlike EEG dimensional complexity, EEG nonlinearity (difference between original and surrogate data) was not affected by smoking. This indicates that, under resting conditions, smoking/nicotine may have a modulating effect on input from the reticular activating system, with such input having a global, linearizing effect on cortical dynamics. Nonlinear dynamics resulting from intracortical processes appear not to be affected.

IN order to test for functional competence in thin pieces of isolated tissue containing muscular elements, such as the skin of the rat (which contains smooth muscle and a sheet of skeletal muscle known as the panniculus carnosus)', a bath was devised in which the muscles could be excited directly or indirectly by transmural stimulation1. The response of the stimulated muscle provided a measure of functional competence in the surviving tissue. This bath and also our method of recording the pressure changes developed in it are described here.
