Nitrogen and phosphorus frequently limit terrestrial plant production, but have a mixed record in regulating the abundance of terrestrial invertebrates. We contrasted four ways that Na could interact with an NP fertilizer to shape the plants and invertebrates of an inland prairie. We applied NP and Na to m(2) plots in a factorial design. Aboveground invertebrate abundance was independently co-limited by NaCl and NP, but with +NP plots supporting more individuals. We suggest the disparity arises because NP enhanced plant height by 35% (1SD) over controls, providing both food and habitat while NaCl provides only food...

Immunotherapy is considered a new treatment option for many tumor entities, as decades of research into cancer immunotherapy have recently yielded promising results. Indeed, impressive clinical results of checkpoint blockade inhibitors in malignant melanoma and non-small cell lung cancer indicate the therapeutic potential of tumor-specific immune restoration. Over the years, different immunotherapeutic approaches have been evaluated for the treatment of hepatocellular carcinoma (HCC) with some respectable results...

Background and aims: Hepatic steatosis is the basis of non-alcoholic fatty liver disease (NALFD). Mere fat accumulation within hepatocytes is considered the mild form of NAFLD, but can progress in some patients to advanced steatohepatitis (NASH), which may lead to fibrosis, cirrhosis or hepatocellular carcinoma. However, even hepatic steatosis alone may be a risk factor for cardiovascular disease (CVD). Patients and methods: In the present real life study 106 patients from the outpatient clinic of the Department for Gastroenterology and Hepatology with either NAFLD (n = 60) or other typical diagnoses (n = 46) were included...

The relationship between stressful life transitions and wellbeing is well established, however, the protective role of social connectedness has received mixed support. We test two theoretical models, the Stress Buffering Hypothesis and the Social Identity Model of Identity Change, to determine which best explains the relationship between social connectedness, stress, and wellbeing. Study 1 (N=165) was an experiment in which participants considered the impact of moving cities versus receiving a serious health diagnosis...

OBJECTIVE: Certain aspects of the anterior cerebral artery (ACA) cortical branches tend to vary, including absent or additional arteries, variation in origin, and changes to diameter and length. Knowledge of these factors can be crucial in aneurysm and arteriovenous malformation surgery. Few studies report on these aspects and a South African study have not been completed. Therefore, the aim of this study is to report absent or additional arteries, the origin, diameter and length of ACA cortical branches in a Western Cape population...

A mixture of water/carbon dioxide is a "green" perspective solvent from the viewpoint of biomedical applications. Clathrate hydrates are formed this solvent under certain conditions and a very interesting question is the impact of clathrates hydrates on the structure and properties of bovine pericardium, which is used in biomedicine, in particular as a main part of biological heart valve prostheses. The aim of the present work is to investigate the influence of clathrates on the structure and mechanical properties of the collagen tissue treated with chitosan in H2O/CO2 mixtures under pressure 3...

The infrapatellar adipose body (Hoffa's fat pad, IFP) is situated between the patellar tendon, the femoral condyle and the tibial plateau. The IFP consists of lobules of white adipose tissue delimited by thin connective septa. The actual structural functionality of the IFP is debated and should pertain to a cushioning role in the knee joint, providing to distribute and to damp mechanical stresses during articular activity. The present study is aimed to analyze the correlation between histological configuration and mechanical properties of the IFP, compared to other adipose tissues, partially differentiated by composition and conformation...

Coronary artery vasospasm (constriction) caused by reduced nitric oxide bioavailability leads to myocardial infarction. Reduced endothelial release of nitric oxide by the neurotransmitter acetylcholine, leads to paradoxical vasoconstriction as it binds to smooth muscle cell M3 receptors. Thus, inhibition of coronary artery vasospasm will improve clinical outcomes. Inhibition of insulin regulated aminopeptidase has been shown to improve vessel function, thus we tested the hypothesis that HFI419, an inhibitor of insulin regulated aminopeptidase, could reduce blood vessel constriction to acetylcholine...

PURPOSE: Urodynamic studies are crucial to neuropathic bladder management and they often determine surgical intervention. However, current evidence indicates that interpretations show poor agreement across physicians. We sought to determine the interrater reliability of urodynamic interpretation in our practice. We hypothesized that there would be strong correlation among pediatric urologists of similar training in a single academic practice. MATERIALS AND METHODS: We retrospectively identified patients with neuropathic bladder who underwent urodynamics at our institution between 2014 and 2015...

BACKGROUND: TB patients co-infected with HIV have worse treatment outcomes than non-coinfected patients. How clinical characteristics of TB and socioeconomic characteristics influence these outcomes is poorly understood. Here, we use polytomous regression analysis to identify clinical and epidemiological characteristics associated with unfavorable treatment outcomes among TB-HIV co-infected patients in Brazil. METHODS: TB-HIV cases reported in the Brazilian information system (SINAN) between January 1, 2001 and December 31, 2011 were identified and categorized by TB treatment outcome (cure, default, death, and development of MDR TB)...

OBJECTIVE: Minority stress theory is one of the primary theories used to understand substance use among lesbian, gay, and bisexual populations. This study tested whether drinking to cope with stress (DTC), loneliness, and gay community participation (GCP) mediated the relationship between one type of minority stress (i.e., internalized heterosexism) and behavioral health outcomes. METHOD: Using secondary data analysis and the PROCESS procedure, relationships between internalized heterosexism, the mediators (DTC, loneliness, and GCP), and outcomes (heavy drinking, alcohol problems, and psychological distress) were explored, both cross-sectionally and in a lagged manner, among both treatment-seeking and non-treatment-seeking problem drinking men who have sex with men...

OBJECTIVE: The need to be thin is pervasive in adolescent culture and is associated with increased risk outcomes among adolescent girls. Body image and behavioral misperception (BIBM) exists when there is a disconnect between body weight perception and actions taken related to perceived weight status. To understand this further, we examined the relationship between BIBM and alcohol use among high school girls in the United States. METHOD: Using 2013 Youth Risk Behavior Survey data, we ran survey-weighted multivariable logistic regression analyses to examine BIBM and (a) lifetime alcohol use, (b) current alcohol use, and (c) current heavy episodic drinking (≥5 drinks in a few hours) among female high school students (N = 6,579)...

OBJECTIVE: This secondary data analysis examined patterns of drinking during alcohol treatment and associated drinking outcomes during the first year following treatment. The goal was to provide clinicians with guidance on which patients may be most at risk for negative long-term outcomes based on drinking patterns during treatment. METHOD: This study was an analysis of existing data (N = 3,851) from three randomized clinical trials for alcohol use disorder: the COMBINE Study (n = 1,383), Project MATCH (n = 1,726), and the United Kingdom Alcohol Treatment Trial (n = 742)...
