BACKGROUND AND PURPOSE: Inflammatory bowel disease (IBD) is a chronic and relapsing inflammatory disorder of gastrointestinal tract, and the dysfunction of immune regulation plays a critical role in IBD. Reflecting the limited use of current drugs and therapies for IBD treatment, it is necessary to explore novel drugs or therapies for this disease. We investigated the effect of cambogin in a mouse model of dextran sulphate sodium (DSS)-induced colitis and whether cambogin attenuates inflammation via Treg-cell-mediated immune modulation...

Treatment outcomes in diffuse large B-cell lymphoma (DLBCL) following standard R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) therapy is highly variable and dependent on a number of clinical, biologic, and genetic features. The identification of molecular heterogeneity via gene expression profiling dichotomizes patients based on the cell of origin (COO) model into germinal center B-cell-like (GCB) and activated B-cell-like (ABC) subsets, with ABC-DLBCL having a worse outcome...

BACKGROUND: Sipuleucel-T is an autologous cell-based cancer immunotherapy for men with asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC). Its approval by the Food and Drug Administration was based on demonstration of an overall survival (OS) benefit in randomized placebo-controlled phase III trials. However, treatment was associated with a prostate-specific antigen (PSA) decline in only a small minority of patients. Understanding the clinical factors that are associated with OS could help guide treatment decisions, including patient selection and the timing of sipuleucel-T relative to other therapies...

OBJECTIVES: Arteriovenous malformations (AVMs) are complex vascular lesions. Surgical excision is the treatment of choice, but is often not achievable. Embolo-sclerotherapy alone is associated with high recurrence rates. This study tested the hypothesis that seeding hydrogel conditioned bone marrow derived mesenchymatous stem cells (BM-MSCs) in an AVM nidus model induces solid microvascular occlusion through endoluminal tissue growth. METHODS: AVMs were modelled as arteriovenous microvascular nidus, using swine rete mirabile, a plexiform intracranial structure composed of arterial microvessels that extensively anastomose...

Errors during mRNA translation can lead to a reduction in the levels of functional proteins and an increase in deleterious molecules. Advances in next-generation sequencing have led to the discovery of rare genetic disorders, many caused by mutations in genes encoding the mRNA translation machinery, as well as to a better understanding of translational dynamics through ribosome profiling. We discuss here multiple neurological disorders that are linked to errors in tRNA aminoacylation and ribosome decoding. We draw on studies from genetic models, including yeast and mice, to enhance our understanding of the translational defects observed in these diseases...

The lung is a delicately balanced and highly integrated mechanical system. Lung tissue is continuously exposed to the environment via the air we breathe, making it susceptible to damage. As a consequence, respiratory diseases present a huge burden on society and their prevalence continues to rise. Emergent function is produced not only by the sum of the function of its individual components but also by the complex feedback and interactions occurring across the biological scales - from genes to proteins, cells, tissue and whole organ - and back again...

According to the 2015 Global Burden of Disease Study, diarrhea ranked ninth among causes of death for all ages, and fourth among children under 5 years old, accounting for an estimated 499,000 deaths in this young age group. It was also the second most common cause of years lived with disability (2.39 billion YLDs). The goal of the WHO/UNICEF Integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhea (GAPPD) is to reduce deaths from diarrhea in children under 5 years of age to less than 1 per 1000 live births, by 2025...

BACKGROUND AND PURPOSE: Multiple sclerosis (MS) is a complex disease of the central nervous system. As new drugs are becoming available, knowledge on diagnosis and treatment must continuously evolve. There is therefore a need for a reference tool compiling current data on benefit and safety, to aid professionals in treatment decisions and use of resources across Europe. The European Committee of Treatment and Research in Multiple Sclerosis (ECTRIMS) and the European Academy of Neurology (EAN) have joined forces to meet this need...

BACKGROUND: Postharvest diseases result in major losses in fruits. Tomato is susceptible to postharvest rot caused by B. cinerea and is regarded as a good model system to study postharvest disease and quality deterioration in fruit. To develop a safe and effective technique to alleviate disease and maintain fruit quality, the effects of methyl salicylate (MeSA) or 1-methylcyclopropene (1-MCP) either separately or combined on quality and gray mold caused by B. cinerea in tomato fruit were investigated...

BACKGROUND: Dichotomous models like Milan Criteria represent the routinely used tools for predicting the outcome of patients with hepatocellular carcinoma (HCC). However, a paradigm shift from a dichotomous to continuous prognostic stratification should represent a good strategy for improving the prediction process. Recently, the tumor burden score (TBS) has been proposed for selecting patients with colorectal liver metastases. To date, TBS has not been validated in a large HCC population...

BACKGROUND: The ability to provide accurate prognostic data after hepatectomy for intrahepatic cholangiocarcinoma (ICC) remains poor. We sought to develop and validate a nomogram to predict survival, as well as investigate the clinical implications of underestimating patients' risk of recurrence. METHODS: Patients undergoing curative-intent resection of ICC between 1990 and 2015 at 14 major hepatobiliary centers were included. Variables significant on multivariable analysis were used to construct a nomogram to predict disease-free survival (DFS)...

BACKGROUND: The American Joint Committee on Cancer (AJCC) uses the same nodal staging system for cutaneous and mucosal squamous cell carcinoma of the head and neck in its 8th edition (AJCC 8) despite differences in the etiology, risk factors, and clinical behavior of the two diseases. This study aims to evaluate the performance of the AJCC 8 nodal staging system by direct comparison of cutaneous (cSCC) versus oral squamous cell carcinoma (oSCC) patients. METHODS: Patients with metastatic cSCC (N = 382) and oSCC (N = 325) were identified from a prospective database (years 1987-2016)...

There is evidence for insulin resistance in drug-naïve first-episode schizophrenia (Sz) patients. We have tested whether impaired insulin homeostasis is also present in first-episode patients with major depression (MD) and if this can be discerned from stress-related and medication effects. Homeostatic model assessment of insulin resistance (HOMA-IR) was determined in a cross-sectional cohort study of acute first-episode drug-naïve patients with MD (n = 18) or Sz (n = 24), and healthy controls (C, n = 43)...

OBJECTIVES: We aimed to investigate if lesion-specific ischaemia by invasive fractional flow reserve (FFR) can be predicted by an integrated machine learning (ML) ischaemia risk score from quantitative plaque measures from coronary computed tomography angiography (CTA). METHODS: In a multicentre trial of 254 patients, CTA and invasive coronary angiography were performed, with FFR in 484 vessels. CTA data sets were analysed by semi-automated software to quantify stenosis and non-calcified (NCP), low-density NCP (LD-NCP, < 30 HU), calcified and total plaque volumes, contrast density difference (CDD, maximum difference in luminal attenuation per unit area) and plaque length...

Activation of CD4 T cells leads to their metabolic reprogramming which includes enhanced glycolysis, catalyzed through hexokinase enzymes. Studies in some systems indicate that the HK2 isoform is the most up regulated isoform in activated T cells and in this report the relevance of this finding is evaluated in an infectious disease model. Genetic ablation of HK2 was achieved in only T cells and the outcome was evaluated by measures of T cell function. Our results show that CD4 T cells from both HK2 depleted and WT animals displayed similar responses to in vitro stimulation and yielded similar levels of Th1, Treg or Th17 subsets when differentiated in vitro...

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma (KS). It is endemic in a number of sub-Saharan African countries with infection rate of >50%. The high prevalence of HIV-1 coupled with late presentation of advanced cancer staging make KS the leading cancer in the region with poor prognosis and high mortality. Disease markers and cellular functions associated with KS tumorigenesis remain ill-defined. Several studies have attempted to investigate changes of the gene profile with in vitro infection of monoculture models, which are not likely to reflect the cellular complexity of the in vivo lesion environment...

Our aims were to describe physical activity (PA) behaviour in Spain and to examine its association with the prevalence of some of the major non-communicable diseases and with the use of prescription medication. Individualized secondary data retrieved from the 2014 European Health Interview Survey (EHIS) for Spain were used to conduct a cross-sectional epidemiological study (n = 18926). PA was assessed by two different measures: a specific designed variable for EHIS and a leisure time PA frequency-based query of the national survey...
