Recently, epidemiologic studies have shown that the lack of vitamin D levels may be associated with high asthma prevalence, but its effect is still controversial, depending on season, area, and food consumption. We aimed to examine the association of serum vitamin D levels with the prevalence of pediatric asthma in Korea. A total of 80 children (50 asthmatic children and 30 healthy controls) aged 6-14 years were participated in this study. Serum 25-hydroxy vitamin D (vitamin D) levels were measured and compared between the two groups...

A review of more than 20 years of experience with vibratory stimulation in vestibular diseases is given. Vibrations in a frequency frame of 30-60 Hz are applied on the mastoid during 20 s. Eye movements are recorded by video-oculography to detect a vibration-induced nystagmus (VIN). A VIN occurs in cases of a side difference between the peripheral vestibular receptors beating to the side of better excitability. In patients with central lesions, a VIN does not appear generally, only exceptionally if the lesion is located laterally in the brain stem...

To maintain upright posture and prevent falling, balance control involves the complex interaction between nervous, muscular and sensory systems, such as sensory reweighting. When balance is impaired, compliant foam mats are used in training methods to improve balance control. However, the effect of the compliance of these foam mats on sensory reweighting remains unclear. In this study, eleven healthy subjects maintained standing balance with their eyes open while continuous support surface (SS) rotations disturbed the proprioception of the ankles...

PURPOSE: We examined the expression, clinical correlation and functional mechanisms of endogenous microRNA-424 (miR-424) in human non-small cell lung cancer (NSCLC). METHODS: Expression pattern of endogenous miR-424 was examined by qRT-PCR in clinical samples obtained from 233 NSCLC patients. Correlations between differential miR-424 expression level (low vs. high) and NSCLC patients' clinicopathological parameters or survival were statistically examined. In in vitro NSCLC H596 and SW900 cells, miR-424 was either upregulated or downregulation by lentiviral transduction...

OBJECTIVE: Endoscopic examination followed by tissue biopsy is the gold standard in the evaluation of lesions of the upper aerodigestive tract. However, it can be difficult to distinguish between healthy mucosa, dysplasia, and invasive carcinoma. Optical coherence tomography (OCT) is a non-invasive technique which acquires high-resolution, cross-sectional images of tissue in vivo. Integrated into a surgical microscope, it allows the intraoperative evaluation of lesions simultaneously with microscopic visualization...

In animals, a Western style diet-high in saturated fat and added sugar-causes impairments in hippocampal-dependent learning and memory (HDLM) and perception of internal bodily state (interoception). In humans, while there is correlational support for a link between Western-style diet, HDLM, and interoception, there is as yet no causal data. Here, healthy individuals were randomly assigned to consume either a breakfast high in saturated fat and added sugar (Experimental condition) or a healthier breakfast (Control condition), over four consecutive days...

OBJECTIVES: Muscular targets that are deep or inaccessible to surface electromyography (sEMG) require intrinsic recording using fine-wire electromyography (fEMG). It is unknown if fEMG validly record cortically evoked muscle responses compared to sEMG. The purpose of this investigation was to establish the validity and agreement of fEMG compared to sEMG to quantify typical transcranial magnetic stimulation (TMS) measures pre and post repetitive TMS (rTMS). The hypotheses were that fEMG would demonstrate excellent validity and agreement compared with sEMG...

BACKGROUND: In 2014-2015, we assessed favipiravir tolerance and efficacy in patients with Ebola virus (EBOV) disease (EVD) in Guinea (JIKI trial). Because the drug had never been used before for this indication and that high concentrations of the drugs were needed to achieve antiviral efficacy against EBOV, a pharmacokinetic model had been used to propose relevant dosing regimen. Here we report the favipiravir plasma concentrations that were achieved in participants in the JIKI trial and put them in perspective with the model-based targeted concentrations...

The safety and high quality of ethnic ready-to-eat foods as a source of nourishment and food supplies chain to the remote areas become particularly important. Consuming healthy and balanced nutritional foods means eating better quality foods in proper quantities. Such foods can be developed through a preservation technique by using ionizing radiation. Although implementation of the technology for certain foodstuffs has been implemented in some countries, application of the process to a complete set of meals for selected target groups is still very limited...

Organochlorine chemicals and lead are environmental exposures that have endocrine disrupting properties (EDCs) which interfere with many aspects of hormone action. Childhood and adolescence are windows of susceptibility for adverse health effects of EDCs. Our ongoing study, the Russian Children's Study (RCS), is one of the few longitudinal studies investigating the impact of EDCs on growth and puberty in boys. It is conducted in the historically contaminated city of Chapaevsk, in the Samara region. The study focuses on evaluating the associations of persistent organochlorine chemicals and lead with growth and pubertal timing...

BACKGROUND: CYP1A2 and CYP2A6 are polymorphic drug-metabolising enzymes that are also implicated in the activation of procarcinogens in humans. Some of their alleles and haplotypes, often varied in prevalence across populations, are thought to influence activity despite the known contribution of environmental factors. This study assessed the potential influence of some genetic variants of CYP1A2 and CYP2A6 on metabolic phenotypes in Nigerians. METHODS: Genomic DNA was extracted from blood samples of 100 healthy, unrelated subjects for whom CYP1A2 and CYP2A6 phenotypes had previously been determined, alongside an additional 80 other individuals for whom phenotype data were unavailable...

Among the long-term effects of the Chornobyl disaster the greatest concern of international medical and scientific community is given to the established fact of excess of the spontaneous level of cancer incidence in the exposed population. According to mo-dern concepts, the accumulation of chromosome aberrations, especially in radiosensitive cells, could be potentially oncogenic, and low doses of ionizing radiation could be promoters of the radiation-induced carcinogenesis. The results of our studies have shown that such substances as thymalin, inosine, ascorbic acid, caffeine could modify radiation-induced cytogenetic effects in peripheral blood lymphocytes of healthy individuals and exert protective or sensitizing action dependent on their concentrations, cell radiosensitivity, dose of irradiation, and relative biologic effectiveness of ionizing radiation...

BACKGROUND: Polyomavirus-associated nephropathy (PVAN) following BK virus reactivation in kidney transplant recipients (KTR) can compromise graft survival. Lowering immunosuppression is the only established approach to prevent or treat PVAN but nonspecifically increasing host immune competence also augments rejection risk. Ex vivo T cell stimulation/expansion offers the possibility to generate BK-specific T cell lines for adoptive immunotherapy. The objective of this study was to develop and characterize a clinical scale protocol to generate BK-specific T cell lines from viremic KTR...

Trauma-induced coagulopathy is associated with adverse patient outcome. Animal models demonstrate that histone deacetylase inhibitors, such as valproic acid (VPA), improve survival following injury. While in-vivo data suggest that improved survival may in part be because of an attenuation of coagulopathy, it remains unknown whether this is a direct effect of the drug, or the establishment of an overall prosurvival phenotype. We thus conducted an ex-vivo experiment to determine if VPA has an effect on coagulation and platelet function...

Among various biomaterials used as scaffolds in tissue engineering, silk fibroin is a highly attractive material. A scaffold should be biocompatible and nontoxic, with optimal physical features and mechanical properties. For this reason, tissue-engineering approaches in regenerative medicine have focused on investigating the biocompatibility of possible biomaterials by analyzing cell-scaffold interaction properties. The aim of the present study was to examine the biocompatibility of silk fibroin as a film (two-dimensional [2D]) and a scaffold (three-dimensional [3D]) after being cellularized with human dental pulp stem cells (hDPSCs)...

OBJECTIVES: To provide musculoskeletal ultrasound (MSKUS) images of hand anatomy in the position of hemiparetic flexion as a reference for spasticity injections. After a stroke, spasticity can result in anatomic distortion of the hand. Spasticity may require treatment with botulinum toxin or phenol injections. Anatomic distortion may decrease the accuracy of injections. Standard anatomic references are of limited utility because they are not in this spastic hemiparetic position. There presently is no anatomic reference in the literature for these spastic postures...

With their ability to recognize and eliminate virus-infected and neoplastic cells, natural killer cells (NK-cells) represent an important part of the innate immune system. NK-cells have attracted the attention of exercise scientists for more than thirty years ago. To date, it is widely accepted that NK-cell counts in the peripheral blood are strongly influenced by acute exercise. Additionally, many studies reported effects of both, acute and chronic exercise on NK-cell cytotoxicity. However, these findings are contradictory...
