Can teaching hospitals use serial formative OSCEs to improve student performance?

Background We report on interns’ clinical competence and experiences of an objective structured clinical examination (OSCE) training program over 3 years. We aimed to determine whether repeated formative OSCEs allow teaching hospitals to improve the effectiveness of clinical training and help interns to achieve high scores in the national summative OSCE. Methods This study included ...

LHC signatures for the cascade seesaw mechanism

The cascade seesaw mechanism generates neutrino mass for higher-dimension (5+4$n$) operators through the tree-level diagram which brings the seesaw scale down to TeV. We investigate its collider signatures that are within reach of the LHC. In particular, both Type-II scalar and Type-III fermion seesaw signatures exist in such a scenario. Under the assumption that there are no mass ...

Involvement of hippocampal acetylcholinergic receptors in electroacupuncture analgesia in neuropathic pain rats

Background Cumulating evidence has shown a close correlation between electroacupuncture stimulation (EAS) frequency-specific analgesic effect and central opioid peptides. However, the actions of hippocampal acetylcholinergic receptors have not been determined. This study aims to observe the effect of different frequencies of EAS on the expression of hippocampal muscarinic and ...

Transfer of Dicamba Tolerance from Sinapis arvensis to Brassica napus via Embryo Rescue and Recurrent Backcross Breeding

Auxinic herbicides (e.g. dicamba) are extensively used in agriculture to selectively control broadleaf weeds. Although cultivated species of Brassicaceae (e.g. Canola) are susceptible to auxinic herbicides, some biotypes of Sinapis arvensis (wild mustard) were found dicamba resistant in Canada. In this research, dicamba tolerance from wild mustard was introgressed into canola ...

Isolation of vaccinia JX594 from pustules following therapy for hepatocellular carcinoma

Background JX594 is an oncolytic poxvirus derived from Wyeth strain vaccinia virus. We reported the presentation of cutaneous and mucosal pustules containing laboratory-confirmed JX594 in a patient following injection of JX594. Case presentation A 36-year-old man was diagnosed hepatitis B virus-associated hepatocellular carcinoma on September 19, 2011. Despite treatment with ...

The Prognostic Value of Forkhead Box P3 Expression in Operable Breast Cancer: A Large-Scale Meta-Analysis

Background Recent studies have shown that the forkhead box P3 (FOXP3) protein has a prognostic role in breast cancer. However, these results are controversial. Therefore, the aim of this meta-analysis was to clarify the prognostic role of FOXP3 expression in operable breast cancer cases. Methods Eligible studies describing the use of FOXP3 as a prognostic factor for operable breast ...

Posterior transpedicular approach with circumferential debridement and anterior reconstruction as a salvage procedure for symptomatic failed vertebroplasty

Background Complications and failure of vertebroplasty, such as cement dislodgement, cement leakage, or spinal infection, usually result in spinal instability and neural element compression. Combined anterior and posterior approaches are the most common salvage procedure for symptomatic failed vertebroplasty. The purpose of this study is to evaluate the feasibility and efficacy of ...

Metabolomics Reveals Dynamic Metabolic Changes Associated with Age in Early Childhood

Objectives A detailed understanding of the metabolic processes governing rapid growth in early life is still lacking. The aim of this study was to investigate the age-related metabolic changes in healthy children throughout early childhood. Methods Healthy children from a birth cohort were enrolled in this study from birth through 4 years of age. Urinary metabolites were assessed ...

Enhanced Particulate Organic Carbon Export at Eddy Edges in the Oligotrophic Western North Pacific Ocean

Mesoscale eddies in the subtropical oligotrophic ocean are ubiquitous and play an important role in nutrient supply and oceanic primary production. However, it is still unclear whether these mesoscale eddies can efficiently transfer CO2 from the atmosphere to deep waters via biological pump because of the sampling difficulty due to their transient nature. In 2007, particulate ...

Modulation of Human Macrophage Responses to Mycobacterium tuberculosis by Silver Nanoparticles of Different Size and Surface Modification

Exposure to silver nanoparticles (AgNP) used in consumer products carries potential health risks including increased susceptibility to infectious pathogens. Systematic assessments of antimicrobial macrophage immune responses in the context of AgNP exposure are important because uptake of AgNP by macrophages may lead to alterations of innate immune cell functions. In this study we ...

Binary icosahedral flavor symmetry for four generations of quarks and leptons

To include the quark sector, the $A_{5}\equiv I$ (icosahedron) four generation lepton model is extended to a binary icosahedral symmetry I′ flavor model. We find that the masses of fermions, including the heavy sectors, can be accommodated. At leading order the Cabibbo–Kobayashi–Maskawa (CKM) matrix is the identity and the Pontecorvo–Maki–Nakagawa–Sakata (PMNS) matrix, resulting ...

The Incidence and Risk Factors of Meningitis after Major Craniotomy in China: A Retrospective Cohort Study

Background Meningitis after neurosurgery can result in severe morbidity and high mortality. Incidence varies among regions and limited data are focused on meningitis after major craniotomy. Aim This retrospective cohort study aimed to determine the incidence, risk factors and microbiological spectrum of postcraniotomy meningitis in a large clinical center of Neurosurgery in China. ...

Thymoquinone Induces Cell Death in Human Squamous Carcinoma Cells via Caspase Activation-Dependent Apoptosis and LC3-II Activation-Dependent Autophagy

Background Thymoquinone (TQ), an active component of Nigella sativa or black cumin, elicits cytotoxic effects on various cancer cell lines. However, the anti-cancer effects of TQ on head and neck squamous cell carcinoma (HNSCC) remain unclear. Methodology/Principal Findings In this study, TQ elicited a strong cytotoxic effect on SASVO3, a highly malignant HNSCC cell line. The ...

Association Between Recent Use of Proton Pump Inhibitors and Nontyphoid Salmonellosis: A Nested Case-Control Study

Background. The association between proton pump inhibitors (PPIs) and nontyphoid salmonellosis (NTS) continues to be debated.
