BACKGROUND: Employers are increasingly relying on rewards programmes in an effort to promote greater levels of activity among employees; however, if enrolment in these programmes is dominated by active employees, then they are unlikely to be a good use of resources. OBJECTIVE: This study uses a stated-preference survey to better understand who participates in rewards-based physical activity programmes, and to quantify stated uptake by active and insufficiently active employees...

Large tumor suppressor (LATS) is an important member of the Hippo pathway which can regulate organ size and cell proliferation. However, very little is known about the expression and clinical significance of LATS in lung cancer especially from this part of the world. We elucidated the frequency of LATS1 &LATS2 promoter hypermethylation (by methylation-specific PCR) and expression (by real-time PCR) in sixty nine (n = 69) Non-Small Cell Lung Cancer (NSCLC) patients and their corresponding normal lung tissue samples...

The C-Repeat Binding Factors (CBFs) are DNA-binding transcriptional activators that were identified using Arabidopsis thaliana. In barley, Hordeum vulgare, a cluster of CBF genes reside at FROST RESISTANCE-H2, one of two loci having major effects on winter-hardiness. FR-H2 was revealed in a population derived from the winter barley 'Nure' and the spring barley 'Trèmois'. 'Nure' harbors two to three copies of CBF2A and CBF4B as a consequence of tandem iteration of the genomic region encompassing these genes whereas 'Trèmois' harbors single copies, and these copy number differences are associated with their transcript level differences...

Chimeric antigen receptor (CAR) T cell therapy is a promising cancer treatment that has recently been undergoing rapid development. However, there are still some major challenges, including precise tumor targeting to avoid off-target or "on-target/off-tumor" toxicity, adequate T cell infiltration and migration to solid tumors and T cell proliferation and persistence across the physical and biochemical barriers of solid tumors. In this review, we focus on the primary challenges and strategies to design safe and effective CAR T cells, including using novel cutting-edge technologies for CAR and vector designs to increase both the safety and efficacy, further T cell modification to overcome the tumor-associated immune suppression, and using gene editing technologies to generate universal CAR T cells...

Transfer is a desired outcome of simulation-based training, yet evidence for how instructional design features promote transfer is lacking. In clinical reasoning, transfer is improved when trainees experience instruction integrating basic science explanations with clinical signs and symptoms. To test whether integrated instruction has similar effects in procedural skills (i.e., psychomotor skills) training, we studied the impact of instruction that integrates conceptual (why) and procedural (how) knowledge on the retention and transfer of simulation-based lumbar puncture (LP) skill...

Transmission of infectious agents might be associated with iatrogenic actions of charitable help in health care. An example is the vaccination against yellow fever in USA that transmitted hepatitis B virus. Another example is injections of praziquantel for treatment and cure of schistosomiasis in Central and Northern Africa, with a focus in Egypt that has spread hepatitis C virus. There is no indication that human T-lymphotropic virus type 1 was spread by injection treatment for African trypanosomiasis, syphilis and treponematosis, but these treatments might have contributed to the early spread of human immunodeficiency virus type 1 (HIV-1) in Central Africa...

Hyperoside is a major active constituent in many medicinal plants traditionally used in Chinese medicines for their anti-inflammatory, antioxidative, and vascular protective effects. Recent studies have focused on the protective effects of hyperoside on hyperlipidemia. However, the molecular mechanisms underlying these effects are unknown. In this study, vascular smooth muscle cells (VSMCs) were treated in vitro with oxidized low-density lipoprotein (oxLDL) in the presence or absence of hyperoside. Western blotting, quantitative PCR, and tetrazolium assay were used to detect lectin-like oxLDL receptor-1 (LOX-1) expression and extracellular signal-regulated kinases (ERK) activation, and to determine VSMCs viability...

PURPOSE OF REVIEW: Adipocytes have adapted to store energy in the form of lipid and also secrete circulating factors called adipokines that signal to other tissues to coordinate energy homeostasis. These functions are disrupted in the setting of obesity, promoting the development of diseases such as diabetes, cardiovascular disease, and cancer. RECENT FINDINGS: Obesity is linked to an increased risk of many types of cancer and increased cancer-related mortality...

PerR, a member of Fur family protein, is a metal-dependent H2O2 sensing transcription factor that regulates genes involved in peroxide stress response. Industrially important bacterium Bacillus licheniformis contains three PerR-like proteins (PerRBL, PerR2, and PerR3) compared to its close relative Bacillus subtilis. Interestingly, unlike other bacteria including B. subtilis, no authentic perR BL null mutant could be established for B. licheniformis. Thus, we constructed a conditional perR BL mutant using a xylose-inducible promoter, and investigated the genes under the control of PerRBL...

We generated an alternative reverse genetics (RG) system based on a synthesized swine 45S rRNA promoter to rescue the H3N2 subtype swine influenza virus. All eight flanking segment cassettes of A/swine/Henan/7/2010 (H3N2) were amplified with ambisense expression elements from RG plasmids. All segments were then recombined with the pHC2014 vector, which contained the synthesized swine 45S rRNA promoter (spol1) and its terminal sequence (t1) in a pcDNA3 backbone. As a result, we obtained a set of RG plasmids carrying the corresponding eight-segment cassettes...

Problematic patterns of gambling and their harms are known to have culturally specific expressions. For ethnic Chinese people, patterns of superstitious belief in this community appear to be linked to the elevated rates of gambling-related harms; however, little is known about the mediating psychological mechanisms. To address this issue, we surveyed 333 Chinese gamblers residing internationally and used a mediation analysis to explore how gambling-related cognitive biases, gambling frequency and variety of gambling forms ('scope') mediate the association between beliefs in luck and gambling problems...

The inhibitory immune checkpoint PD-L1/PD1 promotes the alternative splicing of the FKBP5 gene, resulting in increased expression of its variant 4 in the peripheral blood mononuclear cells of melanoma patients. The variant 4 transcript is translated into the truncated FKBP51s protein. Given the importance of co-inhibitory signalling in tumour immune escape, here we tested the potential for using FKBP51s expression to predict immunotherapy outcomes. To do this, we immunophenotyped PBMCs from 118 melanoma patients and 77 age- and sex-matched healthy controls...

Integrating gammaretroviral vectors can dysregulate the expression of cellular genes through a variety of mechanisms, leading to genotoxicity and malignant transformation. Although most attention has focused on the activation of cellular genes by vector enhancers, aberrant fusion transcripts involving cellular gene sequences and vector promoters, vector splice elements, and vector transcription termination sequences have also been mechanistically associated with dysregulated expression of cellular genes. Chromatin insulators have emerged as an effective tool for reducing the frequency of vector-mediated genotoxicity and malignant transformation and have been shown to block the activation of cellular genes by vector enhancers...

Mesenchymal stem cell (MSC)-derived exosomes have been recognized as new candidates for the treatment of degenerative diseases or injury and may provide an alternative to cell-based therapy. However, the compositions in MSC-derived exosomes are highly influenced by the microenvironment in which their original cells reside. Here, we hypothesized that a nitric oxide (NO)-releasing polymer can boost the proangiogenic compositions of exosomes and enhance their proangiogenic capacity. Our results demonstrated that exosomes, released from human placenta-derived MSCs (hP-MSCs) by NO stimulation, augment the angiogenic effects of human umbilical vein endothelial cells (HUVECs) in vitro...

Graphene quantum dots (GQDs) has been widely used in enormous fields, however, the inherent molecular mechanism of GQDs for potential risks in biological system is still elusive to date. In this study, the outstanding reduced graphene quantum dots (rGOQDs) with the QY as high as 24.62% were successfully synthesized by the improved Hummers method and DMF hydrothermal treatment approach. The rGOQDs were N-doped photoluminescent nanomaterials with functional groups on the surface. The fluorescent bio-imaging was performed by exposing zebrafish in different concentrations of the as-prepared rGOQDs, and the distribution of rGOQDs was successfully observed...

Functional foods provide health benefits if they are consumed on a regular basis as part of a varied diet. In this review, we discuss the availability and role of functional foods in pet nutrition with a focus on dogs and cats. Indeed, functional foods modify gastrointestinal physiology, promote changes in biochemical parameters, improve brain functions and may reduce or minimize the risk of developing specific pathologies. This evidence derives largely from clinical studies while only limited evidence is available from studies in dogs and cats...

Low temperature climate presented a technical challenge to start-up composting in northern region of China. This study investigated if the cold-adapted microbial consortium (CAMC) could promote composting start-up at low temperature. In this work, the CAMC was inoculated when food waste was composted at 10°C. The results showed that inoculating CAMC accelerated the piles temperature effectively, the piles passed through the start-up period within 37h. Moreover, the inoculants could enhance the abundances of dominant strains related to organic matters degradation rate...
