Part 2: Preparing Entry-Level Occupational and Physical Therapy Students to Promote Healthy Lifestyles Emphasizing Healthy Eating with Individuals with Disabilities

Rehabilitation professionals including occupational therapists (OT) and physical therapists (PT) are increasingly called upon to incorporate health promotion of lifestyle behaviors including physical activity and healthy eating into routine clinical care. While OTs and PTs may be comfortable promoting activity-related behaviors, many are less comfortable with nutrition behaviors. To address entry-level OT and PT students’ perceived discomfort with discussing diet-related behaviors, faculty developed a healthy eating module for students to use during a community-based service learning program. The purpose of this paper is to describe the formative evaluation process of developing the healthy eating module, and to discuss results of a pilot trial of this module. The formative assessment of the healthy eating module consisted of four steps: focus groups with students, key informant interviews with community partners, expert panel round table, and expert panel review of materials. Students (n=117) completed questionnaires at the end of the service learning program to assess how much they used the new resources, and how useful they found the resources. The final healthy eating module consisted of an on-line training session and a healthy eating toolkit, including resources for assessments, treatment activities and additional nutrition information. Mann-Whitney U tests indicated that students who reported high use of materials found the resources significantly more helpful than those students who reported low use (

Part 1: Preparing Entry-Level Occupational Therapy and Physical Therapy Students to Promote Health and Wellbeing with Individuals with Disabilities

To address accreditation standards for health and wellbeing within entry-level occupational therapy (OT) and physical therapy (PT) programs, the OT, PT, and Human Studies Departments at the University of Alabama at Birmingham (UAB) collaborated with community partners to conduct an interdisciplinary service learning activity based on the I Can Do It, You Can Do It Program (ICDI). This program is a structured community health program where individuals without disabilities are partnered with individuals with disabilities to enhance physical activity, healthy eating, and community participation. The purpose of this paper is to describe a formative evaluation of ICDI at UAB, and to discuss revisions to the program made as a result of the evaluation. Faculty used a qualitative design to collect feedback on perceived benefits and challenges of the program. Focus groups were conducted with students who completed the program, and key informant interviews were conducted with site coordinators from each of the three partnering community sites. Two themes emerged from student focus groups: (1) Program benefits, with sub-themes of hands-on application and interaction, and (2) Challenges with suggestions for change, with sub-themes of preparation, communication, and expectations. Four themes emerged from key informant interviews: (1) Students, (2) Logistics, (3) Program benefits, and (4) Transference. Results of this evaluation led to a number of revisions for the 2016 cohort. Future evaluations will include objective measures of change in student knowledge over time, as well as health and behavioral outcomes of community members who participated in the ICDI program at UAB

Ritonavir blocks AKT signaling, activates apoptosis and inhibits migration and invasion in ovarian cancer cells

<p>Abstract</p> <p>Background</p> <p>Ovarian cancer is the leading cause of mortality from gynecological malignancies, often undetectable in early stages. The difficulty of detecting the disease in its early stages and the propensity of ovarian cancer cells to develop resistance to known chemotherapeutic treatments dramatically decreases the 5-year survival rate. Chemotherapy with paclitaxel after surgery increases median survival only by 2 to 3 years in stage IV disease highlights the need for more effective drugs. The human immunodeficiency virus (HIV) infection is characterized by increased risk of several solid tumors due to its inherent nature of weakening of immune system. Recent observations point to a lower incidence of some cancers in patients treated with protease inhibitor (PI) cocktail treatment known as HAART (Highly Active Anti-Retroviral Therapy).</p> <p>Results</p> <p>Here we show that ritonavir, a HIV protease inhibitor effectively induced cell cycle arrest and apoptosis in ovarian cell lines MDH-2774 and SKOV-3 in a dose dependent manner. Over a 3 day period with 20 μM ritonavir resulted in the cell death of over 60% for MDAH-2774 compared with 55% in case of SKOV-3 cell line. Ritonavir caused G1 cell cycle arrest of the ovarian cancer cells, mediated by down modulating levels of RB phosphorylation and depleting the G1 cyclins, cyclin-dependent kinase and increasing their inhibitors as determined by gene profile analysis. Interestingly, the treatment of ritonavir decreased the amount of phosphorylated AKT in a dose-dependent manner. Furthermore, inhibition of AKT by specific siRNA synergistically increased the efficacy of the ritonavir-induced apoptosis. These results indicate that the addition of the AKT inhibitor may increase the therapeutic efficacy of ritonavir.</p> <p>Conclusion</p> <p>Our results demonstrate a potential use of ritonavir for ovarian cancer with additive effects in conjunction with conventional chemotherapeutic regimens. Since ritonavir is clinically approved for human use for HIV, drug repositioning for ovarian cancer could accelerate the process of traditional drug development. This would reduce risks, limit the costs and decrease the time needed to bring the drug from bench to bedside.</p

Measurement of the flavour composition of dijet events in pp collisions at root s=7 TeV with the ATLAS detector

This paper describes a measurement of the flavour composition of dijet events produced in pp collisions at &#8730;s=7 TeV using the ATLAS detector. The measurement uses the full 2010 data sample, corresponding to an integrated luminosity of 39 pb−1. Six possible combinations of light, charm and bottom jets are identified in the dijet events, where the jet flavour is defined by the presence of bottom, charm or solely light flavour hadrons in the jet. Kinematic variables, based on the properties of displaced decay vertices and optimised for jet flavour identification, are used in a multidimensional template fit to measure the fractions of these dijet flavour states as functions of the leading jet transverse momentum in the range 40 GeV to 500 GeV and jet rapidity |y|&#60;2.1. The fit results agree with the predictions of leading- and next-to-leading-order calculations, with the exception of the dijet fraction composed of bottom and light flavour jets, which is underestimated by all models at large transverse jet momenta. The ability to identify jets containing two b-hadrons, originating from e.g. gluon splitting, is demonstrated. The difference between bottom jet production rates in leading and subleading jets is consistent with the next-to-leading-order predictions

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Search for high-mass resonances decaying to dilepton final states in pp collisions at s√=7 TeV with the ATLAS detector

The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying to an electron-positron pair or a muon-antimuon pair. The search is sensitive to heavy neutral Z′ gauge bosons, Randall-Sundrum gravitons, Z * bosons, techni-mesons, Kaluza-Klein Z/γ bosons, and bosons predicted by Torsion models. Results are presented based on an analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 4.9 fb−1 in the e + e − channel and 5.0 fb−1 in the μ + μ −channel. A Z ′ boson with Standard Model-like couplings is excluded at 95 % confidence level for masses below 2.22 TeV. A Randall-Sundrum graviton with coupling k/MPl=0.1 is excluded at 95 % confidence level for masses below 2.16 TeV. Limits on the other models are also presented, including Technicolor and Minimal Z′ Models

Search for R-parity-violating supersymmetry in events with four or more leptons in sqrt(s) =7 TeV pp collisions with the ATLAS detector

A search for new phenomena in final states with four or more leptons (electrons or muons) is presented. The analysis is based on 4.7 fb−1 of $\sqrt{s}=7\;\mathrm{TeV}$ proton-proton collisions delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in two signal regions: one that requires moderate values of missing transverse momentum and another that requires large effective mass. The results are interpreted in a simplified model of R-parity-violating supersymmetry in which a 95% CL exclusion region is set for charged wino masses up to 540 GeV. In an R-parity-violating MSUGRA/CMSSM model, values of m 1/2 up to 820 GeV are excluded for 10 < tan β < 40

Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at root s=7 TeV with the ATLAS detector

A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7TeV recorded with the ATLAS detector at the Large Hadron Collider. The data were recorded in 2011 and correspond to an integrated luminosity of 4.7 fb-1 to 4.8 fb-1. Higgs boson decays into oppositely-charged muon or τ lepton pairs are considered for final states requiring either the presence or absence of b-jets. No statistically significant excess over the expected background is observed and exclusion limits at the 95% confidence level are derived. The exclusion limits are for the production cross-section of a generic neutral Higgs boson, φ, as a function of the Higgs boson mass and for h/A/H production in the MSSM as a function of the parameters mA and tan β in the mhmax scenario for mA in the range of 90GeV to 500 GeV.

‘It's all the way you look at it, you know’: reading Bill ‘Bojangles’ Robinson's film career

This paper engages with a major paradox in African American tap dancer Bill ‘Bojangles’ Robinson's film image – namely, its concurrent adherences to and contestations of dehumanising racial iconography – to reveal the complex and often ambivalent ways in which identity is staged and enacted. Although Robinson is often understood as an embodiment of popular cultural imagery historically designed to dehumanise African Americans, this paper shows that Robinson's artistry displaces these readings by providing viewing pleasure for black, as much as white, audiences. Robinson's racially segregated scenes in Dixiana (1930) and Hooray for Love (1935) illuminate classical Hollywood's racial codes, whilst also showing how his inclusion within these otherwise all-white films provides grounding for creative and self-reflexive artistry. The films' references to Robinson's stage image and artistry overlap with minstrelsy-derived constructions of ‘blackness’, with the effect that they heighten possible interpretations of his cinematic persona by evading representational conclusion. Ultimately, Robinson's films should be read as sites of representational struggle that help to uncover the slipperiness of performances of African American identities in 1930s Hollywood
