The Effects of Therabands on Collegiate Pitchers Rotator Cuff

This study looks at the effects that the rab and shave on the strength and mobility in the dominant rotator cuff of a collegiate pitcher. Collegiate pitchers should strengthen their rotator cuff muscles in order to prevent injuries. Injuries to the rotatorcuff could be season-ending and require surgery for repair. In order to prevent a pitchers chances of getting surgery, they need to find away to strengthen those muscles and make them more mobile. Therabands are a great way to increase strength and mobility in the rotator cuff.https://digitalcommons.gardner-webb.edu/exercise-science-research-proposal-posters/1035/thumbnail.jp

The Effects of Submaximal Fatigue on the Y-Balance Test scores

The purpose of this study was to assess how scores on the Y -balance test differed before and after submaximal fatigue. It was hypothesized that submaximal fatigue would cause Y-Balance Test scores to decrease in the anterior, posteromedial, and posterolateral directions.https://digitalcommons.gardner-webb.edu/exercise-science-research-proposal-posters/1036/thumbnail.jp

Predictors of latent tuberculosis treatment initiation and completion at a U.S. public health clinic: a prospective cohort study

Background Treatment of latent tuberculosis infection (LTBI) is a key component in U.S. tuberculosis control, assisted by recent improvements in LTBI diagnostics and therapeutic regimens. Effectiveness of LTBI therapy, however, is limited by patients’ willingness to both initiate and complete treatment. We aimed to evaluate the demographic, medical, behavioral, attitude-based, and geographic factors associated with LTBI treatment initiation and completion of persons presenting with LTBI to a public health tuberculosis clinic. Methods Data for this prospective cohort study were collected from structured patient interviews, self-administered questionnaires, clinic intake forms, and U.S. census data. All adults (>17 years) who met CDC guidelines for LTBI treatment between January 11, 2008 and May 6, 2009 at Wake County Health and Human Services Tuberculosis Clinic in Raleigh, North Carolina were included in the study. In addition to traditional social and behavioral factors, a three-level medical risk variable (low, moderate, high), based on risk factors for both progression to and transmission of active tuberculosis, was included for analysis. Clinic distance and neighborhood poverty level, based on percent residents living below poverty level in a person’s zip code, were also analyzed. Variables with a significance level <0.10 by univariate analysis were included in log binomial models with backward elimination. Models were used to estimate risk ratios for two primary outcomes: (1) LTBI therapy initiation (picking up one month’s medication) and (2) therapy completion (picking up nine months INH therapy or four months rifampin monthly). Results 496 persons completed medical interviews and questionnaires addressing social factors and attitudes toward LTBI treatment. 26% persons initiated LTBI therapy and 53% of those initiating completed therapy. Treatment initiation predictors included: a non-employment reason for screening (RR 1.6, 95% CI 1.0-2.5), close contact to an infectious TB case (RR 2.5, 95% CI 1.8-3.6), regular primary care(RR 1.4, 95% CI 1.0-2.0), and history of incarceration (RR 1.7, 95% CI 1.0-2.8). Persons in the “high” risk category for progression/transmission of TB disease had higher likelihood of treatment initiation (p < 0.01), but not completion, than those with lower risk. Conclusions Investment in social support and access to regular primary care may lead to increased LTBI therapy adherence in high-risk populations

CSF somatostatin in Alzheimer's disease and major depression: Relationship to hypothalamic-pituitary-adrenal axis and clinical measures

Patients with Alzheimer's disease (AD) and major depression have been shown to have overlapping clinical symptoms and biological markers, including decreased concentrations of cerebrospinal fluid (CSF) somatostatin-like immunoreactivity (SLI), which may be related to alterations in the hypothalamic-pituitary-adrenal axis activity. As in prior studies, we found that CSF SLI was significantly decreased in a group of AD patients (N = 49) and a group of elderly patients with major depression (N = 18), as compared with 13 age-matched controls (F[2, 77] = 12.9, p r = 0.49, p r = 0.47, p r = -0.51, p &lt; .03). Clinical measures of dementia severity and depression did not consistently correlate with CSF SLI in either patient group.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31089/1/0000766.pd

Ester hydrolysis: Conditions for acid autocatalysis and a kinetic switch

Autocatalysis can be used to obtain a sharp switch in state after a programmable time lag. Here, autocatalysis driven by acid concentration during the dissolution and hydrolysis of solid esters was investigated. In a generic model of the process, conditions were identified for observation of a kinetic switch with the introduction of an inhibitor species, bicarbonate, to delay the onset of autocatalysis. The kinetic profiles from the hydrolysis of two esters, d-gluconic acid δ-lactone and dl-lactide, were examined and evidence for dissolution-limited acid autocatalysis was obtained with lactide

Sex Differences in the Effects of Acute and Chronic Stress and Recovery after Long-Term Stress on Stress-Related Brain Regions of Rats

Studies show that sex plays a role in stress-related depression, with women experiencing a higher vulnerability to its effect. Two major targets of antidepressants are brain-derived neurotrophic factor (BDNF) and cyclic adenosine monophosphate response element–binding protein (CREB). The aim of this study was to investigate the levels of CREB, phosphorylation of CREB (pCREB), and BDNF in stress-related brain regions of male and female rats after stress and recovery. CREB and pCREB levels were examined in CA1, CA2, CA3, paraventricular nucleus of the thalamus (PVT), amygdala, anterior cingulate area, dorsal part (ACAd), and infralimbic area of prefrontal cortex (PFC), whereas dentate gyrus (DG) and prelimbic area (PL) of PFC were examined for BDNF levels. Our results demonstrate that levels of CREB and pCREB in male CA1, CA2 and CA3, PVT, amygdala, and ACAd were reduced by stress, whereas the same brain regions of female rats exhibited no change. BDNF levels were decreased by chronic stress in female PL but were increased by acute stress in female DG. BDNF levels in male DG and PL were found not to undergo change in response to stress. Abnormalities in morphology occurred after chronic stress in males but not in females. In all cases, the levels of CREB, pCREB, and BDNF in recovery animals were comparable to the levels of these proteins in control animals. These findings demonstrate a sexual dimorphism in the molecular response to stress and suggest that these differences may have important implications for potential therapeutic treatment of depression

Nanohelicoidal Nematic Liquid Crystal Formed by a Non‐Linear Duplexed Hexamer

The twist‐bend modulated nematic liquid crystal phase exhibits phenomena of fundamental importance to science; the formation of a helical pitch of nanometre scale in a fluid and the spontaneous breaking of mirror symmetry leading to a quasi‐fluid state composed of chiral domains despite being composed of an achiral material. We note that this phase has only been observed for materials with two or more mesogenic units, the manner of attachment between which is always linear. In this communication we report on non‐linear oligomers, with a H‐shaped hexamesogen found to exhibit both nematic and twist‐bend modulated nematic phases. This shatters the widely held assumption that a linear sequence of mesogenic units is a prerequisite for this phase, and points to this state of matter being exhibited by a much wider range of self‐assembling structures than was previously envisaged. The present results support the double helix model of the TB phase as opposed to the simple heliconical model. This new class of materials has the potential to act as low molecular weight surrogates for cross linked liquid‐crystalline elastomers

Hippocampal radial glial subtypes and their neurogenic potential in human fetuses and healthy and Alzheimer's disease adults

Neuropathological conditions might affect adult granulogenesis in the adult human dentate gyrus. However, radial glial cells (RGCs) have not been well characterized during human development and aging. We have previously described progenitor and neuronal layer establishment in the hippocampal pyramidal layer and dentate gyrus from embryonic life until mid-gestation. Here, we describe RGC subtypes in the hippocampus from 13 gestational weeks (GW) to mid-gestation and characterize their evolution and the dynamics of neurogenesis from mid-gestation to adulthood in normal and Alzheimer's disease (AD) subjects. In the pyramidal ventricular zone (VZ), RGC density declined with neurogenesis from mid-gestation until the perinatal period. In the dentate area, morphologic and antigenic differences among RGCs were observed from early ages of development to adulthood. Density and proliferative capacity of dentate RGCs as well as neurogenesis were strongly reduced during childhood until 5 years, few DCX+ cells are seen in adults. The dentate gyrus of both control and AD individuals showed Nestin+ and/or GFAPδ+ cells displaying different morphologies. In conclusion, pools of morphologically, antigenically, and topographically diverse neural progenitor cells are present in the human hippocampus from early developmental stages until adulthood, including in AD patients, while their neurogenic potential seems negligible in the adult.
