While photovoltaic (PV) renewable energy production has surged, concerns remain about whether or not PV power plants induce a "heat island" (PVHI) effect, much like the increase in ambient temperatures relative to wildlands generates an Urban Heat Island effect in cities. Transitions to PV plants alter the way that incoming energy is reflected back to the atmosphere or absorbed, stored, and reradiated because PV plants change the albedo, vegetation, and structure of the terrain. Prior work on the PVHI has been mostly theoretical or based upon simulated models...

: Term born infants are predisposed to human rhinovirus (HRV) lower respiratory tract infections (LRTI) by reduced neonatal lung function and genetic susceptibility. Our aim was to investigate whether prematurely born infants were similarly predisposed to HRV LRTIs or any other viral LRTIs. Infants born less than 36 weeks of gestational age were recruited. Prior to neonatal/maternity unit discharge, lung function (functional residual capacity by helium gas dilution and multiple breath washout, lung clearance index and compliance (Crs), and resistance (Rrs) of the respiratory system) was assessed and DNA samples assessed for eight single nucleotide polymorphisms (SNPs) in seven genes: ADAM33, IL10, MMP16 NFκB1A,SFTPC, VDR, and NOS2A...

OBJECTIVES: Cortical bone drilling for preparation of screw placement is common in multiple surgical fields. The heat generated while drilling may reach thresholds high enough to cause osteonecrosis. This can compromise implant stability. Orthopedic drill bits are several orders more expensive than their similarly sized, publicly available industrial counterparts. We hypothesize an industrial bit will generate less heat during drilling, and the bits will not generate more heat after multiple cortical passes...

INTRODUCTION: To date, no study has reported on the public's opinion of orthopaedic resident duty-hour requirements (DHR). METHODS: A survey was administered to people in orthopaedic waiting rooms and at three senior centers. Responses were analyzed to evaluate seven domains: knowledge of duty hours; opinions about duty hours; attitudes regarding shift work; patient safety concerns; and the effects of DHRs on continuity of care, on resident training, and on resident professionalism...

Patients with tuberculosis (TB) pose a risk to other patients and health care workers, and outbreaks in health care settings occur when appropriate infection control measures are not used. In this article, we discuss strategies to prevent transmission of Mycobacterium tuberculosis within health care settings. All health care facilities should have an operational TB infection control plan that emphasizes the use of a hierarchy of controls (administrative, environmental, and personal respiratory protection). We also discuss resources available to clinicians who work in the prevention and investigation of nosocomial transmission of M tuberculosis...

Primary sarcomas of the thumb metacarpal are rare malignant lesions. Surgical treatment involves amputation versus tumor resection with thumb reconstruction. If complete tumor resection is possible, thumb preservation may be considered, as the thumb is vital to hand function. Following tumor resection, previous reports have described graft reconstruction with fusion to the trapezium or scaphoid. We present two cases of sarcoma necessitating resection of the thumb metacarpal that were reconstructed with an arthrodesis of the proximal phalanx to the second metacarpal shaft...

The ATP synthase (F-ATPase) is a highly complex rotary machine that synthesizes ATP, powered by a proton electrochemical gradient. Why did evolution select such an elaborate mechanism over arguably simpler alternating-access processes that can be reversed to perform ATP synthesis? We studied a systematic enumeration of alternative mechanisms, using numerical and theoretical means. When the alternative models are optimized subject to fundamental thermodynamic constraints, they fail to match the kinetic ability of the rotary mechanism over a wide range of conditions, particularly under low-energy conditions...

Contemporary models of personality assume a hierarchical structure in which broader traits contain narrower traits. Individual differences in response styles also constitute a source of score variance. In this study, the bifactor model is applied to separate these sources of variance for personality subscores. The procedure is illustrated using data for two personality inventories-NEO Personality Inventory-Revised and Zuckerman-Kuhlman-Aluja Personality Questionnaire. The inclusion of the acquiescence method factor generally improved the fit to acceptable levels for the Zuckerman-Kuhlman-Aluja Personality Questionnaire, but not for the NEO Personality Inventory-Revised...

BACKGROUND: Although previous studies suggest that exposure to traffic-related pollution during childhood increases risk of childhood overweight or obesity (COWO), the role of early-life exposure to fine particulate matter (aerodynamic diameter <2.5 micrometers, PM2.5) and its joint effect with mother's pre-pregnancy body mass index (MPBMI) on COWO remain unclear. OBJECTIVES: The present study was conducted to examine the individual and joint effects of ambient PM2...

AbstractIn order to develop novel host/pathogen real- time PCR assays for routine diagnostic use, early gene expression patterns from both Epstein-Barr virus (EBV) and Raji cells were examined after inducing the lytic life cycle using 12-O-tetradecanoyl-13-phorbol ester (TPA) and sodium butyrate. Real-time PCR identified several highly induced (>90-fold) EBV lytic genes over a 48 hr time-course during the lytic induction phase. Latent genes were induced at low levels during this phase. The cellular response to lytic viral replication is poorly understood...

BACKGROUND: In order to compare open reduction and internal fixation (ORIF) with locked plating to hemiarthroplasty for the treatment of three- and four-part proximal humerus fractures, we compared two groups of patients treated during the same time period. MATERIALS AND METHODS: Sixty-five patients who underwent repair of a three- or four-part proximal humerus fracture with locked plates (Group A) were identified in a prospective database and were compared to 29 patients who underwent hemiarthroplasty for similar injuries (Group B)...

UNLABELLED: Sleep problems have been defined using a variety of definitions. No study has assessed the longitudinal association between infant sleep problems and childhood overweight or obesity using existing definitions of sleep problems. This study used longitudinal data (n = 895) from the multi-site Study of Early Child Care and Youth Development (SECCYD) to investigate the effects of infant sleep problems on childhood weight status in Grade 6. Infants with sleep problems in Phase I (1991) and with complete data through Phase III (2004) of SECCYD were included...

This study aimed to assess variation in parent beliefs about causes of learning and developmental problems in U.S. children with autism spectrum disorder, using data from a nationally representative survey. Results showed that beliefs about a genetic/hereditary cause of learning/developmental problems were most common, but nearly as many parents believed in exposure causes. Forty present of parents had no definite causal beliefs. On multivariate analysis, parents who were non-White, publicly insured or poor were more likely than other parents to endorse exposure causes, or less likely to endorse genetic causes, compared to other parents...

BACKGROUND: With this study, we sought to quantify perioperative changes in driving performance among patients who underwent anatomic or reverse shoulder arthroplasty. METHODS: Using a driving simulator, 30 patients (20 anatomic and 10 reverse total shoulder arthroplasties) were tested preoperatively and at 2 weeks (PO2), 6 weeks (PO6), and 12 weeks (PO12) postoperatively. The total number of collisions, centerline crossings, and off-road excursions (when the vehicle traversed the lateral road edge), and scores on a visual analog scale (VAS) for pain and the Shoulder Pain and Disability Index (SPADI) were recorded at each driving trial...

The Zuckerman-Kuhlman Personality Questionnaire (ZKPQ; Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993 ) was designed for the assessment of personality. The goal of this work was to determine the psychometric properties of the ZKPQ, as well as to establish normative data by gender and age in an outpatient sample attending primary mental health care services. We administered the questionnaire to 314 participants (34.7% males) 18 to 81 years old. The most prevalent primary diagnoses were mood (37.9%) and adjustment disorders (35...

Regulatory decisions are made based on the assessment of risk and benefit of medical devices at the time of pre-market approval and subsequently, when post-market risk-benefit balance needs reevaluation. Such assessments depend on scientific evidence obtained from pre-market studies, post-approval studies, post-market surveillance studies, patient perspective information, as well as other real world data such as national and international registries. Such registries provide real world evidence and are playing a more and more important role in enhancing the safety and effectiveness evaluation of medical devices...

The characterization of protein binding processes - with all of the key conformational changes - has been a grand challenge in the field of biophysics. Here, we have used the weighted ensemble path sampling strategy to orchestrate molecular dynamics simulations, yielding atomistic views of protein-peptide binding pathways involving the MDM2 oncoprotein and an intrinsically disordered p53 peptide. A total of 182 independent, continuous binding pathways were generated, yielding a kon that is in good agreement with experiment...
