Perceived neighborhood safety and exercise behavior among community dwellers in Gauteng, South Africa.

Maintaining a physically active life is an important determinant of overall health and psychosocial wellbeing among adults. Physical exercise behavior can be influenced by various social and environmental circumstances including neighborhood safety. Using data from South Africa Quality of life Survey 2015/16, this study aimed to assess the hypothesis that lack of perceived neighborhood safety (PNS) can reduce the likelihood of engaging in physical exercise (PE).

Impact of Communicating With Doctors Via Social Media on Consumers' E-Health Literacy and Healthy Behaviors in China.

This study investigated the relationship between consumers' communication with doctors and their e-Health literacy and healthy behaviors based on the theory of reasoned action. Five communication activities were identified: following doctors' social media accounts, reading doctors' posts, responding to doctors' posts, favoring (clicking "like" of) doctors' posts, and recommending doctors to other patients. E-Health literacy and healthy behaviors were measured based on instruments used in previous literature.

Effects of the weight of shoes on calf muscle simulation.

The current study investigated the effects of shoes of different weights on calf individual muscle contributions during a running cycle. Twenty male runners ran on a force platform with shoes of four different weights (175 g, 255 g, 335 g, and 415 g). The study evaluated runners' lower extremity muscle forces under the four shoe weight conditions using a musculoskeletal modeling system.

Echinacoside inhibits breast cancer cells by suppressing the Wnt/β-catenin signaling pathway.

Echinacoside, a small molecule derived from the natural herbs Cistanche and Echinacea, shows effective anticancer abilities, but the mechanism remains unclear. By using colony formation, scratch, and transwell assays in MDA-MB-231 breast cancer cells, we confirmed the anti-breast cancer ability of Echinacoside in vitro. In addition, we found that Echinacoside can dose-dependently reduce phosho-LRP6, total LRP6, phosho-Dvl2, active β-catenin, and total β-catenin protein expression level in MDA-MB-231 and MDA-MB-468 cells by western blot.

Dose-time fractionation schedules of preoperative radiotherapy and timing to surgery for rectal cancer.

Chemoradiotherapy (CRT) is extensively used prior to surgery for rectal cancer to provide significantly better local control, but the radiotherapy (RT), as the other component of CRT, has been subject to less interest than the drug component in recent years. With considerable developments in RT, the use of advanced techniques, such as intensity-modulated radiotherapy (IMRT) in rectal cancer, is garnering more attention nowadays. The radiation dose can be better conformed to the target volumes with possibilities for synchronous integrated boost without increased complications in normal tissue.

A three dimension magnetic bio-char composite-based quick, easy, cheap, effective, rugged and safe method for multi-pesticides analysis of vegetables.

To improve the efficiency of high-throughput analysis, a three-dimensional (3D) magnetic FeO-biochar composite was synthesized and used as adsorbent of QuEChERS pretreatment method for the analysis of 49 pesticide residues in vegetables containing complex pigments. The structure evolution mechanism of FeO-biochar was discussed and the structural morphology was confirmed by a series of characterization methods. Multivariate approach was employed to optimize the extraction parameters including sample amount, solvent volume, NaCl amount, extraction time, anhydrous MgSO amount, adsorbent amount, purification time.

Effects of Officials' Cross-Regional Redeployment on Regional Environmental Quality in China.

Cross-regional redeployment (or relocation) of government officials has a significant effect on the local economic development and environmental protection. Based on the panel data of 31 provinces (municipalities) in China from 2001 to 2016 and the environmental pollution index obtained by Entropy method, the dynamic panel regression model was applied to verify the relationship between the officials' cross-regional redeployment and environmental pollution. The results show that environmental pollution was positively correlated with officials' relocation and their tenure after the redeployment.

Interactions of stimulus quality and frequency on N400 in Chinese character recognition: Evidence for cascaded processing.

Event-related brain potentials (ERPs) were recorded during a delayed character-matching (target-probe matching) task to examine the joint effects of stimulus quality (blurriness) and character frequency on the N400. The behavioral results indicated robust interactive effects of stimulus quality and character frequency on response times, suggesting the cascade of pre-lexical activation to the lexical stage. The ERP results showed an interaction between stimulus quality and character frequency on N400-like amplitude.

A novel FeO/graphene oxide/citrus peel-derived bio-char based nanocomposite with enhanced adsorption affinity and sensitivity of ciprofloxacin and sparfloxacin.

To create more active adsorption sites on biochar, the FeO/GO/citrus peel-derived magnetic bio-nanocomposite (mGOCP) with hierarchically porous architectures was synthesized by a facile one-pot hydrothermal approach for efficient removal of fluoroquinolone antibiotics ciprofloxacin (CIP) and sparfloxacin (SPA). The characterization analysis of bio-nanocomposites showed that the incorporation of GO could ensure relatively higher surface area (1556 cm g), more abundant pore structure, and higher thermal stability within mGOCP bio-nanocomposites than FeO/citrus peel-derived magnetic bio-nanocomposites (mCP). And the mGOCP-1% attained outstanding adsorption capacity for CIP (283.

Prefrontal sensitivity to changes in language form and semantic content during speech production.

In bilingual speakers, language switching might involve a change in language form, meaning, or both. However, the neural substrates of language control in the three switching conditions have not been specified. We examined bilingual speech production using a picture-naming paradigm that teased apart language and semantic switching.

Early attentive processing on forged and genuine exemplars by imitators: An ERP study.

Important questions have arisen about the capacity of traditional questioned document methodology to differentiate between genuine and forged exemplars of an author's handwriting. This paper does not address that dispute. The paper describes the first part of a research project investigating whether imitators (forgers) can reliably differentiate between genuine samples and forgeries.

Effects of thalamic infarction on the structural and functional connectivity of the ipsilesional primary somatosensory cortex.

Objectives: To identify regions causally influenced by thalamic stroke by measuring white matter integrity, cortical volume, and functional connectivity (FC) among patients with thalamic infarction (TI) and to determine the association between structural/functional alteration and somatosensory dysfunction.

Methods: Thirty-one cases with TI-induced somatosensory dysfunction and 32 healthy controls underwent magnetic resonance imaging scanning. We reconstructed the ipsilesional central thalamic radiation (CTR) and assessed its integrity using fractional anisotropy (FA), assessed S1 ipsilesional changes with cortical volume, and identified brain regions functionally connected to TI locations and regions without TI to examine the potential effects on somatosensory symptoms.
