Objective: To evaluated the outcome of prevention and treatment for glucocorticoid-induced osteonecrosis of femoral head with anticoagulant and vasodilator drugs. Methods: A prospective, randomized, double-blind study was performed. From August 2003 to August 2006, 58 patients with large amounts of hormone therapy in the Zhongshan Hospital Affiliated Dalian University were enrolled and randomly assigned to the control group (placebo) or preventive group (anticoagulant and vasodilator drugs). And we prospectively analyzed the clinical outcomes of 24 patients with glucocorticoid-induced osteonecrosis of femoral head early stage (treatment group)treated by anticoagulant and vasodilator drugsat the same time...

Combining NK cell adoptive transfer with hypomethylating agents (HMA) is an attractive therapeutic approach for patients with acute myeloid leukemia (AML). However, data regarding the impact of HMA on NK cell functionality are mostly derived from in vitro studies with high non-clinical relevant drug concentrations. Here, we report a comparative study of azacitidine and decitabine in combination with allogeneic NK cells generated from CD34(+) hematopoietic stem and progenitor cells (HSPC-NK cells) in in vitro and in vivo AML models...

BACKGROUND: Randomized controlled trails (RCTs) on viral hepatitis in China have been increasing, but few studies have been systematically conducted to evaluate the reporting quality of RCTs in this field. In the present study, we assessed the reporting quality of RCTs on the treatment of hepatitis B or C from 1991 to 2015 in China. METHODS: Articles published between January 1991 and December 2015 were identified via PubMed, Medline, and Embase by using the key words "randomized clinical trials," "treatment," "therapy," "hepatitis B," "HBV," "hepatitis C," "HCV," "China," and "Chinese...

The aim of this study was to evaluate the clinical significance of N-myc downstream-regulated gene 1 (NDRG1) in colorectal cancer (CRC) patients and to explore the mechanisms governing the role of NDRG1 in apoptosis of CRC cells. In the current study, we found that NDRG1 was a prognostic marker of CRC patients. Moreover, NDRG1 expression negatively correlated to tumor size and clinical TNM stage, suggesting that NDRG1 might act as a tumor suppressor by inhibiting proliferation or inducing apoptosis in CRC. Consistently, substantial apoptosis was observed in vitro and in vivo in the presence of NDRG1...

With the increasing popularity of mountain biking, also known as off-road cycling, and the riders pushing the sport into extremes, there has been a corresponding increase in injury. Almost two thirds of acute injuries involve the upper extremities, and a similar proportion of overuse injuries affect the lower extremities. Mountain biking appears to be a high-risk sport for severe spine injuries. New trends of injury patterns are observed with popularity of mountain bike trail parks and freeride cycling. Using protective gear, improving technical proficiency, and physical fitness may somewhat decrease the risk of injuries...

Understanding the genetic basis of the switch from asexual to sexual lifestyles in response to sometimes rapid environmental changes is one of the major challenges in fungal ecology. Light appears to play a critical role in the switch-but fungal genomes harbor diverse light sensors. Fungal opsins are homologous to bacterial green-light sensory rhodopsins, and their organismal functions in fungi have not been well understood. Three of these opsin-like proteins were widely distributed across fungal genomes, but homologs of the Fusarium opsin-like protein CarO were present only in plant-associated fungi...

Background Dulanermin is a recombinant soluble human Apo2 ligand/tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) that activates apoptotic pathways by binding to proapoptotic death receptor (DR) 4 and DR5. The purpose of this study was to evaluate the efficacy and safety of dulanermin combined with vinorelbine and cisplatin (NP) as the first-line treatment for patients with advanced non-small-cell lung cancer (NSCLC). Experimental design Patients were randomly assigned to receive NP chemotherapy (vinorelbine 25 mg/m(2) on days 1 and 8 and cisplatin 30 mg/m(2) on days 2 to 4) for up to six cycles plus dulanermin (75 μg/kg on days 1 to 14) or placebo every three weeks until disease progression, intolerable toxicity, or withdrawal of consent...

Intraspecific variation in adult body mass can be particularly high in some insect species, mandating adjustment of the wing's structural properties to support the weight of the larger body mass in air. Insect wings elastically deform during flapping, dynamically changing the twist and camber of the relatively thin and flat aerofoil. We examined how wing deformations during free flight scale with body mass within a species of rose chafers (Coleoptera: Protaetia cuprea) in which individuals varied more than threefold in body mass (0...

Impaired apoptosis and systemic toxicity of chemotherapeutic drugs make cancer treatment suboptimal. Thus, there is urgency for drug repurposing which facilitates discovery of safe and effective combination therapy. This study aimed to evaluate chloroquine's (CQ) ability to trigger TRAIL/TRAILR2 apoptotic pathway in thioacetamide (TAA)-induced hepatocellular carcinoma (HCC) either alone or in combination with doxorubicin (DOX). Moreover, its ability to attenuate DOX-induced cardiotoxicity was investigated. TAA was injected in male Sprague Dawely rats (200 mg/kg; ip; 2 times/week) for 16 weeks...

OBJECTIVE: Tumor necrosis factor (TNF) related apoptosis inducing ligand (TRAIL) can induce the apoptosis of tumor cells, but leaving its effect on malignant lymphoma largely insignificant, as these tumors may develop drug resistance. Chlorambucil (CLB) had definitive treatment efficacy on low-malignant non-Hodgkin lymphoma (NHL), but with unclear efficacy on highly malignant Burkitt lymphoma. A study has been shown that CLB could enhance the sensitivity of chronic lymphatic leukemia cells against TRAIL...

Human activities, from resource extraction to recreation, are increasing global connectivity, especially to less-disturbed and previously inaccessible places. Such activities necessitate road networks and vehicles. Vehicles can transport reproductive plant propagules long distances, thereby increasing the risk of invasive plant species transport and dispersal. Subsequent invasions by less desirable species have significant implications for the future of threatened species and habitats. The goal of this study was to understand vehicle seed accrual by different vehicle types and under different driving conditions, and to evaluate different mitigation strategies...

OBJECTIVE: Executive dysfunction is observed in a sizable number of patients with refractory temporal lobe epilepsy (TLE). The frontostriatal network has been proposed to play a significant role in executive functioning, however, because of the complex architecture of these tracts, it is difficult to generate measures of fiber tract microstructure using standard diffusion tensor imaging. To examine the association between frontostriatal network compromise and executive dysfunction in TLE, we applied an advanced, multishell diffusion model, restriction spectrum imaging (RSI), that isolates measures of intraaxonal diffusion and may provide better estimates of fiber tract compromise in TLE...

BACKGROUND: Alzheimer's disease (AD) biomarkers are emerging as critically important for disease detection and monitoring. Most biomarkers are obtained through invasive, resource-intense procedures. A cognitive marker, intra-individual cognitive variability (IICV) may provide an alternative or adjunct marker of disease risk for individuals unable or disinclined to undergo lumbar puncture. OBJECTIVE: To contrast risk of incident AD and mild cognitive impairment (MCI) associated with IICV to risk associated with well-established biomarkers: cerebrospinal fluid (CSF) phosphorylated tau protein (p-tau181) and amyloid-β 42 (Aβ42) peptide...

Background & Aim: TNF-related apoptosis-inducing ligand (TRAIL) and its cognate receptor(s) are upregulated in human and murine nonalcoholic steatohepatitis (NASH). However, the consequence of this enhanced expression on NASH pathogenesis remains unclear. TRAIL may either accentuate liver injury by promoting hepatic steatosis and inflammation, or it may mitigate the disease process by improving systemic insulin resistance and averting hepatic fibrosis. Herein, we investigated the role of TRAIL in an obesity-induced murine model of NASH...

It is well established that osteoporosis and diabetes are prevalent diseases with significant associated morbidity and mortality. Patients with diabetes mellitus are at an increased risk of bone fractures. Today we have several groups of effective and save antidiabetic drugs, which are very given often in combination. Although diabetes-related complications are important in the etiology, the effects of medications on bone metabolism and fracture risk should not be neglected, because the diabetes medication may affect also bone health and fracture risk...

Lifting the limb sufficiently to clear an obstacle seems like a straightforward task, yet trips are a common cause of falls across all ages. Examination of obstacle contacts in the lab revealed a progressive decrease in foot elevation with repeated exposures, ultimately resulting in failure (Heijnen et al. Exp Brain Res 23:219-231, 2012). The purpose of this study was to determine if the progressive decrease in foot elevation continued when knowledge of obstacle contact was removed. Twenty-one young adults (mean 20...
