Peroxiredoxin 2 (Prx2) is a redox enzyme that is abundantly expressed in red blood cells (RBCs) and has been the focus of clinical attention for monitoring the oxidative status. We previously developed a method to quantify the reduced and hyperoxidized forms of Prx2 in human RBCs using reverse-phase high-performance liquid chromatography (HPLC). In the present study, we investigated the hyperoxidative status of Prx2 at the molecular level in a post-translational modification analysis using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) system...

OBJECTIVES: Bearing in mind the rising prevalence of chronic medical conditions, the chronic disease management is one of the key features required by medical information systems used in primary healthcare. Our research group paid a particular attention to this specific area by offering a set of custom data collection forms and reports in order to improve medical professionals' daily routine. The main idea was to provide an overview of history for chronic diseases, which, as it seems, had not been properly supported in previous administrative workflows...

Obesity and associated pathologies are a dramatically growing problem. New therapies to prevent and/or cure them are strongly needed. Adipose tissue is a logical target for pharmacological intervention, since it is now recognized to exert an important endocrine function, secreting a variety of adipokines affecting, for example, adiposity and insulin resistance. This proof of principle work focuses on the development of novel lipid-mimetic prodrugs reaching fat deposits by the same lymphatic absorption route followed by dietary triglycerides...

Reactive oxygen species have emerged as key participants in a broad range of physiological and pathophysiological processes, not least within the vascular system. Diverse cellular functions which have been attributed to some of these pro-oxidants within the vasculature include the regulation of blood pressure, neovascularisation and vascular inflammation. We here highlight the emerging roles of the enzymatically-generated reaction oxygen species, O2(-) and H2O2, in the regulation of the functions of the gaseous signalling molecules: nitric oxide (NO), carbon monoxide (CO), and hydrogen sulphide (H2S)...

Triadimefon (TF, S-(+)-TF, R-(-)-TF) and its metabolite triadimenol (TN, TN-A1, A2 and TN-B1, B2) are two systemic fungicides and both of them are chiral pharmaceuticals which are widely used in agricultural industry. Many researches focused on the toxicity effects of triadimefon on mammals, while the ecotoxicological data of tiradimefon on reptiles is limited. In order to understand the toxicity mechanism of triadimefon in reptiles, the current study administrated S-(+)-TF or R-(-)-TF traidimefon (50mg/kg(bw)) to Chinese lizards (Eremias argus) respectively, the absorption, distribution of triadimefon and the formation of triadimenol were analysed at different sampling times...

BACKGROUND: Studies regarding postoperative outcomes after primary total hip arthroplasty (THA) in patients who have comorbid factors tend to focus on medical diseases. However, there is a paucity of literature examining the effect of a patient's orthopedic surgical history on outcomes after THA. Significantly, there are currently no studies on the effect of spinal fusion surgery on THA outcomes. METHODS: A review of 82 consecutive patients who had prior spinal fusion surgery who underwent elective THA from January 1, 2006 to December 31, 2015, was conducted...

Since 2013, Norway has engaged in political processes to revise criteria for priority setting. These processes have yielded key efficiency and equity criteria, but excluded potentially relevant social values. This study describes the views of 27 stakeholders in Norway's health system regarding a wider set of priority-setting criteria and procedural characteristics. Between January and February 2016, semi-structured interviews and focus groups were conducted with a purposive sample of policymakers, hospital administrators, practitioners, university students and seniors...

Humoral primary immunodeficiency diseases (hPIDs) are a heterogeneous group of hereditary disorders resulting in abnormal susceptibility to infections of the sinopulmonary tract. Some of these conditions (e.g., common variable immunodeficiency disorders [CVID]) imply a number of non-infectious thoracic complications such as non-infectious airway disorders, diffuse lung parenchymal diseases, and neoplasms. Chest high-resolution computed tomography (HRCT) is a key imaging tool to characterise and quantify the extent of underlying thoracic involvement, as well as to direct and monitor treatment...

Extracellular matrix-based scaffolds derived from mammalian tissues have been used in tissue engineering applications. Among all the tissues, decellularized small intestine submucosal layer (SIS) has been recently investigated for its exceptional characteristics and biocompatibilities. These investigations have been mainly focused on the decellularized porcine SIS; however, there has not been any report on ovine SIS (OSIS) layer. In this study, OSIS was decellularized and its physical, chemical, and morphological properties were evaluated...

We present a critical review of the literature that discusses the link between the level of out-of-pocket payments in developed countries and the share of people in these countries reporting that they postpone or forgo healthcare for financial reasons. We discuss the pros and cons of measuring access problems with this subjective variable. Whereas the quantitative findings in terms of numbers of people postponing care must be interpreted with utmost caution, the picture for the vulnerable groups in society is reasonably robust and unsurprising: people with low incomes and high morbidity and incomplete (or non-existent) insurance coverage are most likely to postpone or forgo healthcare for financial reasons...

This qualitative study explores prostate cancer knowledge and risk in Black college men. Using the Health Belief Model as a guide, focus groups and interviews were conducted with 35 Black males at a historically black college and university. Thematic analysis was conducted and general themes were found. Results indicate that Black college males have very little knowledge and understanding of what their prostate is and what it does. They are also unaware of their risk of developing prostate cancer. Additionally, while many believe prostate cancer is severe, few believe they are susceptible to getting it...

BACKGROUND: With most forms of dementia, the risk of road traffic accidents increases with disease progression. Addressing the issue of fitness to drive at an early stage can help to reduce driving-related risks and simultaneously preserve mobility. General practitioners (GPs) are central contact persons for dementia patients and their relatives in medical and psychosocial matters, and also play a key role in addressing the issue of driving safety. OBJECTIVE: Identification of relevant aspects of managing fitness to drive in dementia, as well as of support requirements for German general practice...

Several studies have demonstrated that injection of double-stranded RNAs (dsRNA) homologous to mRNA for the white spot syndrome virus (WSSV) viral protein 28 (VP28) can induce protection in shrimp against WSSV through RNA interference (RNAi). In comparison to shrimp injected with either PBS or a green fluorescent protein (GFP) nonspecific dsRNA, we obtained nearly complete protection against WSSV infection in shrimp injected with VP28 dsRNA. Upregulation of host genes associated with small RNA silencing was measured 48 hours post treatment in groups injected with dsRNA, and although the VP28-treated group remained moderately upregulated after challenge with WSSV, many-fold higher induction was observed in both control groups reflecting the ongoing viral infection...

It has been reported that younger patients with non-small cell lung cancer (NSCLC) tend to have a better prognosis. Yet, few studies have focused on the clinicopathological characteristics and prognosis of young small cell lung cancer (SCLC), especially for patients with age < 50. In our study, we used Surveillance, Epidemiology, and End Results (SEER) population-based data and identified 16503 patients with SCLC including 711 patients aged < 50, 3338 patients aged 50-59, 5937 patients aged 60-69, 4649 patients aged 70-79 and 1868 patients aged ≥ 80 between 2010 and 2013...

Chronic obstructive pulmonary disease (COPD) is an intractable pulmonary disease that causes widespread and irreversible alveolar collapse. Although COPD occurs worldwide, only symptomatic therapy is currently available. The objective of the present study was the development of therapeutic agents to eradicate COPD. Therefore, we focused on 4-[(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenyl) carbamoyl] benzoic acid (Am80), which is a derivative of all-trans retinoic acid. We evaluated the effects of Am80 on alveolar repair in a novel COPD model of adiponectin-deficient mice...

Epigenetic mechanisms are important for facilitating gene-environment interactions in many disease etiologies, including Fetal Alcohol Spectrum Disorders (FASD). Extensive research into the role of DNA methylation and miRNAs in animal models has illuminated the complex role of these mechanisms in FASD. In contrast, histone modifications have not been as well researched, due in part to being less stable than DNA methylation and less well-characterized in disease. It is now apparent that even changes in transient marks can have profound effects if they alter developmental trajectories...
