#1
Marie Brix Ley, Maiken Kudahl Larsen
Cardiovascular disease is the leading cause of sudden death in the world. The etiology of sudden cardiac death involves a wide range of diseases, but seldom pericardial cysts. A pericardial cyst is an uncommon cyst usually located in the middle mediastinum and rarely in the posterior part. They are usually harmless and asymptomatic. Here, we present a case of a 63-year-old woman who presented with dyspnea and hoarseness, but died suddenly after a CT scan was attempted. The detailed forensic pathologic and histologic examination revealed a pericardial cyst located in the posterior mediastinum...

OBJECTIVE: Introduction:The level of people's health and its preservation is a medical problem that requires the optimal solution and the need to improve the management of the system of measures to achieve the goal. According to specialists, the health of Ukrainian people is accompanied by high mortality, significant parameters of disability and morbidity and a decrease in the average life expectancy. Diseases that lead to such negative medical and social and socio-economic consequences are so-called "illnesses of a way of life" or "diseases of civilization"...

N6-methyladenosine (m6A), one of the most abundant RNA methylation which is ubiquitous in eukaryotic RNA, plays vital roles in many biological progresses. Therefore, the rapid and accurate quantitative detection of m6A is particularly important for its functional research. Herein, a label-free and highly selective electrochemical immunosensor was developed for the detection of m6A. The method is established on that the anti-m6A-Ab can recognize both m6A-RNA and m6A-DNA. An analogous modified DNA probe (L1) serves as a signal molecule, by competing with m6A-RNA for binding to Abs to broaden the linear range...

How to effectively and efficiently reduce carbon dioxide (CO2 ) to value-added chemicals represent a frontier in catalysis research. Due to the high activation energy needs and the endothermic nature of CO2 reduction, the reactions are difficult to carry out. When H2 O is present, hydrogen evolution reactions (HER) often compete favorably with CO2 reduction reactions. For these reactions, catalysts are of critical importance to CO2 reduction. In this article, we review the various metal nanocatalysts for electrochemical CO2 reduction (ECR) reactions...

Catalases reduce oxidative stress by degrading hydrogen peroxide to molecular oxygen and water. The presence of heme-dependent or manganese-dependent catalases was observed for a long time in lactic acid bacteria (LAB) but, to date, knowledge on the factors affecting gene expression and enzymatic functionality are limited to a very few strains. In this study, the effect of atmosphere of incubation (not aerated static growth vs aerated shaken growth) and supplementation with Fe2+ , hemin, Mn2+ or their combinations on the catalase production of respiration-competent strain Lactobacillus casei N87 was evaluated using a 24 factorial design...

An extracellular acidic and thermostable chitinase (HgChi) from thermophilic Humicola grisea was purified and characterized. Enhancement in chitinase production (Qp  = 2.9662 Ul-1  h-1 ) was achieved through derivation of optimum fermentation conditions via central composite design. H. grisea observed to produce various isoforms of chitinase, among which the major expressed form has molecular mass of about 50 kDa. Purified chitinases exhibited optimal activity at pH 3.0 and 70 °C. Chitinase showed notable stability at increasing temperatures...

Purpose: The patient-centered medical home (PCMH) model has been proposed as the ideal model for delivering primary care and is focused on improving patient safety and quality, reducing costs, and enhancing patient satisfaction. The mandated Accreditation Council for Graduate Medical Education educational milestones for evaluation of resident competency represent the skills graduates will utilize after graduation. Many of these skills are reflected in the PCMH model. We sought to determine if residency programs whose main family medicine (FM) practice sites have achieved PCMH recognition are therefore more prepared to evaluate milestones...

The United Nations Security Council passed its first resolution on children in armed conflict in 1999, making it one of the oldest examples of Security Council engagement with a thematic mandate and leading to the creation of a dedicated working group in 2005. Existing theoretical accounts of the Security Council cannot account for the developing substance of the children and armed conflict agenda as they are macro-oriented and focus exclusively on states. I argue that Security Council decision-making on thematic mandates is a productive process whose outcomes are created by and through practices of actors across the three United Nations: member states (the first United Nations), United Nations officials (the second United Nations) and non-governmental organizations (the third United Nations)...

Aedes aegypti is the vector of some of the most important vector-borne diseases like dengue, chikungunya, zika and yellow fever, affecting millions of people worldwide. The cellular processes that follow a blood meal in the mosquito midgut are directly associated with pathogen transmission. We studied the homeostatic response of the midgut against oxidative stress, as well as bacterial and dengue virus (DENV) infections, focusing on the proliferative ability of the intestinal stem cells (ISC). Inhibition of the peritrophic matrix (PM) formation led to an increase in reactive oxygen species (ROS) production by the epithelial cells in response to contact with the resident microbiota, suggesting that maintenance of low levels of ROS in the intestinal lumen is key to keep ISCs division in balance...

BACKGROUND: The human filarial parasites cause diseases that are among the most important causes of morbidity in the developing world. The elimination programs targeting these infections rely on a limited number of drugs, making the identification of new chemotherapeutic agents a high priority. The study of these parasites has lagged due to the lack of reverse genetic methods. METHODOLOGY/PRINCIPAL FINDINGS: We report a novel co-culture method that results in developmentally competent infective larvae of one of the human filarial parasites (Brugia malayi) and describe a method to efficiently transfect the larval stages of this parasite...

INTRODUCTION: Professionalism rests upon a number of individual, environmental, and societal level factors, leading to specific professional behavior in specific situations. Focusing on professional lapses to identify and remediate unprofessional physicians is incomplete. We explored professionalism in practicing internal medicine physicians in the context of everyday practice, to highlight how typical experiences contribute to positive, yet often unnoticed, professional behavior. METHODS: In-depth interviews were used to uncover 13 physicians' most meaningful experiences of professionalism...

This study was carried out to explore the mechanism of LncRNA MALAT-1 as a competing endogenous RNA to regulate miR-124 in epithelial-mesenchymal transition and development of non-small-cell lung cancer (NSCLC). NSCLC and adjacent tissues were collected for RT-qPCR. The correlation of MALAT-1 and miR-124 was analyzed by Pearson. MALAT-1 expression was measured in NSCLC A549, NCI-H460, NCI-H529, SK-MES-1 cells, and 16HBE cells. A549 cells were selected for cell transfection experiments after the creation of six groups...

The Flavivirus genus comprises a diverse group of viruses that utilize a wide range of vertebrate hosts and arthropod vectors. The genus includes viruses that are transmitted solely by mosquitoes or vertebrate hosts as well as viruses that alternate transmission between mosquitoes or ticks and vertebrates. Nevertheless, the viral genetic determinants that dictate these unique flaviviral host and vector specificities have been poorly characterized. In this report, a cDNA clone of a flavivirus that is transmitted between ticks and vertebrates (Powassan lineage II, deer tick virus [DTV]) was generated and chimeric viruses between the mosquito/vertebrate flavivirus, West Nile virus (WNV), were constructed...

BACKGROUND: Subcutaneous implantation of a macroencapsulated patch containing human allogenic islets has been successfully used to alleviate type 1 diabetes mellitus (T1DM) in a human recipient without the need for immunosuppression. The use of encapsulated porcine islets to treat T1DM has also been reported. Although no evidence of pathogen transfer using this technology has been reported to date, we deemed it appropriate to determine if the encapsulation technology would prevent the release of virus, in particular, the porcine endogenous retrovirus (PERV)...

Demand for monoclonal antibodies (mAbs) in basic research and medicine is increasing yearly. Hybridoma technology has been the dominant method for mAb development since its first report in 1975. As an alternative technology, phage display methods for mAb development are increasingly attractive since Humira, the first phage-derived antibody and one of the best-selling mAbs, was approved for clinical treatment of rheumatoid arthritis in 2002. As a non-animal based mAb development technology, phage display bypasses antigen immunogenicity, humanization, and animal maintenance that are required from traditional hybridoma technology based antibody development...

The diagnostic process is a highly complex, problem-solving enterprise. Yet, traditional case reports have not focused directly on this endeavor. Physicians could use the case format to present actual experiences of getting to a diagnosis. This approach would allow for modeling of nonjudgmental, self-reflective practices and also provide information to aid in studying the diagnostic endeavor. Given that diagnostic errors in medicine are widespread and constitute a serious public health problem, it is crucial for physicians to understand the diagnostic process as one step toward improving error rates...
