AIMS: Endothelial cells (ECs) constitute the defensive barrier of vasculature, which maintains the vascular homeostasis. Mitochondrial oxidative stress (mitoOS) in ECs significantly affects the initiation and progression of vascular diseases. The higher serum thyroid stimulating hormone (TSH) level is being recognized as a nonconventional risk factor responsible for the increased risk of cardiovascular diseases in subclinical hypothyroidism (SCH). However, effects and underlying mechanisms of elevated TSH on ECs are still ambiguous...

Generalised Joint Hypermobility including shoulder hypermobility (GJHS) in swimmers is considered an intrinsic risk factor for shoulder injuries. The aim was to investigate the association of GJHS with shoulder strength, fatigue development and muscle activity during swimming-related shoulder rotations. Totally, 38 competitive swimmers (aged 13-17 years) participated, 19 were competitive swimmers with GJHS and 19 were age, sex and club matched swimmers without GJHS. Concentric isokinetic force in medial and lateral rotations were measured at 60°/s (5 repetitions) and 180°/s (10 repetitions)...

Renal recovery after dialysis-requiring acute kidney injury (AKI-D) is an important clinical and patient-centered outcome. Here we examined whether the pre-admission proteinuria level independently influences risk for non-recovery after AKI-D in a community-based population. All adult members of Kaiser Permanente Northern California who experienced AKI-D between January 1, 2009 and September 30, 2015 were included. Pre-admission proteinuria levels were determined by dipstick up to four years before the AKI-D hospitalization and the outcome was renal recovery (survival and dialysis-independence four weeks and more) at 90 days after initiation of renal replacement therapy...

Acute kidney injury (AKI) is associate with high mortality. Despite the evidence of AKI-induced distant organ injury, a relationship between AKI and liver injury has not been clearly established. The goal of this study is to investigate whether renal ischemia-reperfusion (IR) can affect liver pathophysiology. We showed that renal IR in mice induced fatty liver and compromised liver function through the down-regulation of constitutive androstane receptor (CAR; -90.4%) and inhibition of hepatic very low-density lipoprotein-triglyceride (VLDL-TG) secretion (-28...

The rapid expansion of the elderly population has led to the recent epidemic of age-related diseases, including increased incidence and mortality of chronic and acute lung diseases. Numerous studies have implicated aging and oxidative stress in the pathogenesis of various pulmonary diseases; however, despite recent advances in these fields, the specific contributions of aging and oxidative stress remain elusive. This review will discuss the consequences of aging on lung morphology and physiology, and how redox imbalance with aging contributes to lung disease susceptibility...

BACKGROUND AND PURPOSE: Fall-induced injuries and resulting deaths are a serious health problem among older adults. The most common risk factors for falls in older adults are muscle weakness, gait deficiencies, and balance deficits. Patients with end-stage hip osteoarthritis (OA) also have many hip dysfunctions, and these all have the potential to increase the risk of falls. However, the incidence and risk factors for falls in patients with end-stage hip OA remain unclear. The aim of this study was to determine the incidence of falls in women with end-stage hip OA and to identify risk factors for falls in this patient population...

Rotenone is a common pesticide and has been reported as one of the risk factors for Parkinson disease. Rotenone can cause neuronal death or apoptosis through inducing oxidative injury and inhibiting mitochondrial function. As a natural polyphenolic compound, resveratrol possesses the anti-oxidant capacity and neuroprotective effect. However, the mechanism underlying the neuroprotective effect of resveratrol against rotenone-induced neurotoxicity remains elusive. Here, we treated PC12 cells with rotenone to induce neurotoxicity, and the neurotoxic cells were subjected to resveratrol treatment...

Hepatic ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and acute/chronic rejection as well as a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although glucocorticoid receptor (GR) signaling may enhance cytoprotective programs, clinical use of glucocorticoid is limited due to adverse effects, while clinical relevance of GR-facilitated cytoprotection in OLT remains unknown. We aimed to evaluate the significance of hepatic GR in clinical OLT and verify the impact of recombinant human relaxin (rhRLX), which may function as GR agonist in tissue/disease-specific manner...

Mild Traumatic Brian Injury (mTBI) is a common diagnosis and approximately one third of mTBI patients experience a variety of cognitive, emotional, psychosocial and behavioral post-concussion symptoms. When a cluster of these symptoms persists for more than three months they are often classified as post-concussion syndrome (PCS). The objective of this study was to determine prevalence rates, risk factors and functional outcome associated with PCS six months after mTBI applying divergent classification methods...

Lung immaturity is the major cause of morbidity and mortality in premature infants, especially those born <28 weeks of gestation. These infants are at high risk of developing respiratory distress syndrome (RDS), a lung disease caused by insufficient surfactant production and immaturity of saccular/alveolar type II epithelial cells in the lung. RDS treatment includes oxygen and respiratory support that improve survival but also increase the risk for bronchopulmonary dysplasia (BPD), a chronic lung disease characterized by arrested alveolarization, airway hyperreactivity, and pulmonary hypertension...

Childhood physical activity (PA) is important for health across the lifespan. Time pre-schoolers spend outdoors, which has been associated with more PA, is likely influenced by parents' perception of neighbourhood informal social control relevant to pre-schoolers' PA, defined as the willingness of neighbours to intervene to ensure social order and a safe community environment for young children's active play. To advance measurement of this construct, we assessed factorial and construct validities of the PA-related neighbourhood informal social control scale for parents of pre-schoolers (PANISC-PP)...

Background: Hip adductor muscle weakness and a history of groin injury both have been identified as strong risk factors for sustaining a new groin injury. Current groin pain and age have been associated with hip adductor strength. These factors could be related, but this has never been investigated. Purpose: To investigate whether soccer athletes with past-season groin pain and with different durations of past-season groin pain had lower preseason hip adductor squeeze strength compared with those without past-season groin pain...

Hepatofibrosis, which leads to cirrhosis and eventual hepatocellular carcinoma, is a common response to chronic toxin-mediated liver injury. Nitrosamines are potent hepatotoxic agents that cause necrosis and subsequent fibrosis in the liver as a result of cytochrome P450 2E1 (CYP2E1)-dependent metabolism, which generates toxic metabolites that form adducts with nucleic acids, leading to hepatotoxicity and mutagenesis. Herein, CYP2E1 activity and content were determined in fibrotic liver tissue from patients with hepatocellular carcinoma...

Elevated toll-like receptor 4 (TLR4) expression is associated with a high risk of radiation-induced liver disease (RILD). MicroRNA (miR)-146a-5p is a key regulator of lipopolysaccharide (LPS)/TLR4 signaling, but its role in modulation of RILD remains unclear. Here, we found that irradiation and LPS stimulation induced TLR4 and miR-146a-5p expression in the human hepatic stellate cell (HSC) line LX2. Ectopic expression of miR-146a-5p in LX2 inhibited irradiation-induced and LPS-induced pro-inflammatory cytokine secretion and cell proliferation, and promoted cell apoptosis by down-regulating the expression levels of TLR4, interleukin-1 receptor associated kinase 1 (IRAK1), tumor necrosis factor receptor associated factor 6 (TRAF6) and phosphorylation of nuclear factor-kappa B...

OBJECTIVES: After injury, many children experience posttraumatic stress symptoms (PTSS) that negatively impact recovery. Acute pain and PTSS share neurobiological pathways, and acute dosage of morphine has been linked to reduced PTSS in naturalistic studies. However, the complex interactions between pain, morphine and other opioid use, and PTSS have yet to be investigated in robust pediatric samples.This prospective, longitudinal study examined relationships between acute pain, opioid medications, and PTSS after pediatric injury...
