It has been shown that nitrate supplementation can enhance endurance exercise performance. Recent work suggests that nitrate ingestion can also increase intermittent type exercise performance in recreational athletes. We hypothesized that six days of nitrate supplementation can improve high-intensity intermittent type exercise performance in trained soccer players. Thirty-two male soccer players (age: 23 ± 1 years, height: 181 ± 1 m, weight: 77 ± 1 kg, playing experience: 15.2 ± 0.5 years, playing in the first team of a 2nd or 3rd Dutch amateur league club) participated in this randomized, double-blind cross-over study...

Endoplasmic reticulum (ER) stress caused by accumulation of misfolded proteins is observed in several kinds of diseases. Since ER stress is reported to be involved in the progression of non-alcoholic steatohepatitis (NASH), highly sensitive and simple measurement methods are required for research into developing novel therapy for NASH. To investigate the involvement of ER stress in NASH pathogenesis in a mouse model, an assay for liver ER stress was developed using ER stress activated indicator-luciferase (ERAI-Luc) mice...

BACKGROUND: Within- and/or between-instrument variation may falsely indicate patient trends or obscure real trends. We employ a methodology that transforms sequential intra-patient results into estimates of biologic and analytic variation. We previously derived realistic biologic variation (sb) of blood gas (BG) and hematology analytes. We extend this methodology to derive the imprecision of two GEM 4000 BG analyzers. METHODS: A laboratory data repository provided arterial BG, electrolyte and metabolite results generated by two GEM 4000s on ICU patients in 2012-2013...

Chilblain lupus erythematosus (CHLE) is an acral erythema with cutaneous lesion of lupus erythematosus (LE) that is exacerbated during the winter (1). LE/lichen planus (LP) overlap syndrome is a rare cutaneous disorder characterized by mixed histological features of LE and LP at the same lesion (2). Although both CHLE and LE/LP overlap syndrome are immune mediated diseases (3), there is no indication that the same lymphocyte subset induces two distinct cutaneous lesions.

Nilotinib is a second-generation tyrosine kinase inhibitors (TKIs) developed to target the bcr-abl protein for the treatment of chronic myelogenous leukemia (CML). [1] Nilotinib has been described as a well-tolerated drug. The most common non-hematologic side effects are skin rash, pruritus, headache, nausea, and fatigue. Cases of panniculitis induced by the other bcr-able TKIs such as imatinib, dasatinib and ponatinib were rarely described in the literature.[2-5] However, a case of panniculitis induced by nilotinib has not been reported...

Regadenoson is an FDA approved adenosine receptor agonist which increases blood-brain barrier (BBB) permeability in rodents. Regadenoson is used clinically for pharmacologic cardiac stress testing using SPECT or CT imaging agents that do not cross an intact BBB. This study was conducted to determine if standard doses of regadenoson transiently disrupt the human BBB allowing higher concentrations of systemically administered imaging agents to enter the brain. Patients without known intracranial disease undergoing clinically indicated pharmacologic cardiac stress tests were eligible for this study...

Human breast cancers that exhibit high proportions of immune cells and elevated levels of pro-inflammatory cytokines predict poor prognosis. Here, we demonstrate that treatment of human MCF-7 breast cancer cells with pro-inflammatory cytokines results in ERα-dependent activation of gene expression and proliferation, in the absence of ligand or presence of 4OH-tamoxifen (TOT). Cytokine activation of ERα and endocrine resistance is dependent on phosphorylation of ERα at S305 in the hinge domain. Phosphorylation of S305 by IKKβ establishes an ERα cistrome that substantially overlaps with the estradiol (E2)-dependent ERα cistrome...

We investigated the exercise intensity and fitness effects of frequent school-based low-volume high-intensity training for 10 months in 8-10-year-old children. 239 Danish 3rd-grade school children from four schools were cluster-randomised into a control group (CON, n = 116) or two training groups performing either 5 × 12 min/wk small-sided football plus other ball games (SSG, n = 62) or interval running (IR, n = 61). Whole-body DXA scans, flamingo balance, standing long-jump, 20 m sprint, and Yo-Yo IR1 children's tests (YYIR1C) were performed before and after the intervention...

Understanding the rheological properties of soft biological tissue is a key issue for mechanical systems used in the health care field. We propose a simple empirical model using fractional dynamics and exponential nonlinearity (FDEN) to identify the rheological properties of soft biological tissue. The model is derived from detailed material measurements using samples isolated from porcine liver. We conducted dynamic viscoelastic and creep tests on liver samples using a plate-plate rheometer. The experimental results indicated that biological tissue has specific properties: (i) power law increase in the storage elastic modulus and the loss elastic modulus of the same slope; (ii) power law compliance (gain) decrease and constant phase delay in the frequency domain; (iii) power law dependence between time and strain relationships in the time domain; and (iv) linear dependence in the low strain range and exponential law dependence in the high strain range between stress-strain relationships...

Socioeconomic inequalities in health are commonly known to decrease at late age. Yet, it remains unclear whether socioeconomic inequalities in health at late age appear in relation to multimorbidity, particularly in Korea where social support remains unsatisfactory for older people. Using three waves of Korea Health Panel, data of 19,942 observations with repeated measure were constructed to ensure a temporal sequence between three socioeconomic measures (i.e., poverty, employment status, and education) and multimorbidity with a t to t+1 year transition...

Papillary thyroid cancer (PTC) is the most common tumor subtype of thyroid cancer. However, not all PTCs are responsive to current surgical and radioiodine treatment. The well-established clinical prognostic factors include tumor size, lymph node/distal metastasis, and extrathyroidal invasion. The RET/PTC-RAS-BRAF linear molecular signaling cascade is known to mediate PTC pathogenesis. However, whether presence of BRAF mutation, the most common genetic alteration in PTC, can affect PTC behavior and prognosis is controversial...

BACKGROUND: Female soccer has grown extensively in recent years, however differences in gender-specific physiology have rarely been considered. The female reproductive hormones which rise and fall throughout the menstrual cycle, are known to affect numerous cardiovascular, respiratory, thermoregulatory and metabolic parameters, which in turn, may have implications on exercise physiology and soccer performance. Therefore, the main aim of the present study was to investigate potential effects of menstrual cycle phase on performance in soccer specific tests...

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are clinically malignant, having metastatic potential. Histological tumor grade is an accepted indicator of malignant potential, but noninvasive prognostic markers have not yet been identified. This study assessed whether the preoperative neutrophil-to-lymphocyte ratio (NLR) could predict clinical outcomes of PNET patients. METHODS: Fifty-eight patients who underwent curative resection for PNETs between 2001 and 2015 were retrospectively evaluated...

BACKGROUND: Two of the most common types of young-onset dementia (<65 years old) are Alzheimer's disease and frontotemporal lobe dementia (FTLD). A limited amount of research that focuses on the needs of spouses of persons with young-onset FTLD (yo-FTLD) has been published. Thus, we have carried out a study aiming to examine the spouses of yo-FTLD experiences and needs for assistance in daily life. METHOD: Qualitative interviews with 16 informants (aged 51-69 years; nine wives, six husbands and one male cohabitant) were conducted in 2014 and 2015...

The aim of this work was to examine the influence of cryostorage duration of Pinzgau bull's insemination doses (IDs) on some sperm traits. The IDs were frozen by a slow freezing method and stored in liquid nitrogen for different periods: less than 8 years (group 1), 8-13 years (group 2) and 14-18 years (group 3). Motility (CASA), pathological sperm rate (Giemsa staining), apoptotic (Yo-Pro-1-positive) and necrotic (propidium iodide-positive) cell occurrence and fertilizing ability (penetration/fertilization test) of spermatozoa were evaluated post-thaw...

Mee-Hae Kim, Yo Sugawara, Yukako Fujinaga, Masahiro Kino-Oka
The undifferentiated state of human induced pluripotent stem cells (hiPSCs) depends on their cell-cell and cell-substrate adhesions. In this study, we report that exposure to botulinum hemagglutinin (HA), an E-cadherin function-blocking agent, selectively removed cells that deviated from the undifferentiated state in hiPSC colonies. After HA treatment, cell-cell adhesion was disrupted, deviated cells detached from colony centers, and dividing cells filled these spaces. Because E-cadherin-mediated adhesion was disrupted in undifferentiated cells, stress-fiber formation and focal adhesions were diminished; however, these were subsequently restored, and the cells retained expression of undifferentiated stem cell markers and their differentiation potential...

Tamon Miyake, Mariko Tsukune, Yo Kobayashi, Shigeki Sugano, Masakatsu G Fujie
Elderly people are at risk of tripping because of their narrow range of articular motion. To avoid tripping, gait training that improves their range of articular motion would be beneficial. In this study we propose a gait-training robot that applies a torque during the pre-swing phase to achieve this goal. We investigated the relationship between magnitude of applied torque and change in the range of knee-articular motion while walking before and after the application of this torque. We developed a wearable robot and carried out an experiment on human participants in which a motor pulls a string embedded on the robotic frame, applying torque in the pre-swing phase for a period of 20 [s]...

Very-KIND/Kndc1/KIAA1768 (v-KIND) is a brain-specific Ras guanine nucleotide exchange factor carrying two sets of the kinase non-catalytic C-lobe domain (KIND), and is predominantly expressed in cerebellar granule cells. Here, we report the impact of v-KIND deficiency on dendritic and synaptic growth in cerebellar granule cells in v-KIND knockout (KO) mice. Furthermore, we evaluate motor function in these animals. The gross anatomy of the cerebellum, including the cerebellar lobules, layered cerebellar cortex and densely-packed granule cell layer, in KO mice appeared normal, and was similar to wild-type (WT) mice...
