OBJECTIVE: Ecological models have been applied to investigate multiple domains influencing physical activity behaviour, including individual, social, organisational, community, environmental and policy factors. With regard to the built environment, research to date has been limited to small geographical areas and/or small samples of participants. This study examined the geographical association between provision of sport facilities and participation in sport across an entire Australian state, using objective total enumerations of both, for a group of sports, with adjustment for the effect of socioeconomic status (SES)...

T K Padma Shri, N Sriraam
This paper presents a novel ranking method to select spectral entropy (SE) features that discriminate alcoholic and control visual event-related potentials (ERP'S) in gamma sub-band (30-55 Hz) derived from a 64-channel electroencephalogram (EEG) recording. The ranking is based on a t test statistic that rejects the null hypothesis that the group means of SE values in alcoholics and controls are identical. The SE features with high ranks are indicative of maximal separation between their group means. Various sizes of top ranked feature subsets are evaluated by applying principal component analysis (PCA) and k-nearest neighbor (k-NN) classification...

Sexual debut experience may influence HIV/sexual risks among men who have sex with men (MSM). We assessed associations between age of sexual debut and sex of debut partner with recent (past-3-month) sexual/HIV/syphilis risks among 3588 community-based Chinese MSM. Sexual debut with women was associated with more recent (condomless) insertive anal sex with men, more recent (condomless) vaginal sex, and more lifetime female partners. Sexual debut with men was associated with more recent (condomless) receptive anal sex with men and more lifetime male partners...

PURPOSE: Several factors may influence the risk of recurrence after an episode of acute colonic diverticulitis. Until now, a comprehensive systematic overview and evaluation of relevant risk factors have not been presented. This review aimed at assembling and evaluating current evidence on risk factors for recurrence after conservatively treated acute colonic diverticulitis. METHODS: PubMed, Embase, and Cochrane databases were searched for studies evaluating risk factors for recurrence after acute diverticulitis treated non-surgically defined as antibiotic treatment, percutaneous abscess drainage, or by observation...

PURPOSE: Previous studies have shown vascular dysfunction of main conductance arteries and microvessels after diving. We aim to evaluate the impact of bubble formation on vascular function and haemostasis. To achieve this, we used a vibration preconditioning to influence bubble levels without changing any other parameters linked to the dive. METHODS: Twentty-six divers were randomly assigned to one of three groups: (1) the "vibrations-dive" group (VD; n = 9) was exposed to a whole-body vibration session 30 min prior the dive; (2) the "diving" group (D; n = 9) served as a control for the effect of the diving protocol; (3) The "vibration" protocol (V; n = 8) allowed us to assess the effect of vibrations without diving...

: Background and Hypotheses: The growing number of medical television series and the increasing amount of time people spend watching TV will have an influence on what they expect from their treatment in a hospital. We suspect that reality as presented in the media and the actual reality of hospitals are not always conceived of as two different worlds. Many medical TV shows present dramatic, life-threatening operations much more often than they occur in reality. Patients who frequently watch such shows might be induced to believe that even routine operations are often dangerous, which could result in higher levels of fear before such an operation...

Nan Li Ya, ZhiQuan Jiang
OBJECTIVE: Prolactinomas are the most common functional hormone-producing pituitary lesions, accounting for 30-40% of all pituitary tumors, while in autopsy series their incidence reaches 50%. However, patients with prolactinoma had a higher recurrence percentage and rate than patients with acromegaly or Cushing's disease. Furthermore, prolactinomas have the highest rate of recurrence post-surgery as compared with other pituitary adenomas. At present, this behavior of prolactinoma is largely unexplained, but may be related to definition of cure, or to more frequent microscopic tumor infiltration into normal pituitary tissue, which is not removed at surgery...

The objective of this study was to examine the influence of BMI on the passive-elastic properties of the ankle plantarflexors in older women. Twenty-three women, 65-80 yr, were separated into normal weight (NW, BMI <25.0kgm(-2), n=11) and overweight-obese (OW, BMI≥25.0kgm(-2), n=12) groups. Resistive torque of the ankle plantarflexors was recorded on an isokinetic dynamometer by passively moving the ankle into dorsiflexion. Stiffness, work absorption, and hysteresis were calculated across an ankle dorsiflexion angle of 10-15°...

The aim of the current study was to explore the influence that the age and the familiarity of a group majority has on copying fidelity in 4- to 6-year-old children. In Experiment 1, participants (N=120, Mage=68months) viewed five child models, all of whom were either younger than, the same age as, or older than themselves, open a puzzle box using an inefficient technique (four models) or an efficient technique (one model). In Experiment 2 (N=82, Mage=71months), the identical task was presented by groups of unfamiliar models...

This study explored the effects on speech intelligibility of across-formant differences in fundamental frequency (ΔF0) and F0 contour. Sentence-length speech analogues were presented dichotically (left = F1 + F3; right = F2), either alone or-because competition usually reveals grouping cues most clearly-accompanied in the left ear by a competitor for F2 (F2C) that listeners must reject to optimize recognition. F2C was created by inverting the F2 frequency contour. In experiment 1, all left-ear formants shared the same constant F0 and ΔF0F2 was 0 or ±4 semitones...

OBJECTIVES: Depression and negative symptoms have been associated with impaired Quality of life (QoL) in schizophrenia (SZ). However, childhood trauma may influence both QoL and depression in SZ patients, with consequences for the management of impaired QoL in SZ patients. The aim of the present study was to determine if childhood trauma was associated with impaired QoL in schizophrenia. METHOD: A sample of 544 community-dwelling stabilized SZ patients enrolled in FACE-SZ cohort were utilized in this study (74...

OBJECTIVES: Periostin is a matricellular protein, synthesized in the airway epithelium and induced by interleukin (IL)-4 and IL-13. The significance of periostin as a biomarker of T helper type 2 cell (Th2)-induced airway inflammation, and as a measure of the response to Th2-targeted therapy, has recently been highlighted. We explored the relationship between serum periostin and allergic rhinitis in Korean children. METHODS: Data for fifth and sixth grade children from six randomly selected elementary schools located in Jeju and Seogwipo City, Korea, were investigated...

Nitric oxide influences a wide range of cellular functions through S-nitrosylation, a redox-dependent posttranslational protein modification that involves attachment of a nitroso moiety to a reactive thiol group. Over the past two decades, S-nitrosylation has emerged as a ubiquitous mechanism for controlling the activity, subcellular localization, and molecular interactions of proteins, thereby influencing many cellular processes. In addition, recent studies have indicated that aberrant S-nitrosylation may lead to cellular dysfunction and damage...

BACKGROUND: Human and animal health are deeply intertwined in livestock dependent areas. Livestock health contributes to food security and can influence human health through the transmission of zoonotic diseases. In low-income countries diagnosis and treatment of livestock diseases is often carried out by household members who draw upon both ethnoveterinary medicine (EVM) and contemporary veterinary biomedicine (VB). Expertise in these knowledge bases, along with their coexistence, informs treatment and thus ultimately impacts animal and human health...
