Myocardial infarctions go along with biomechanical stress, i.e. stretching of muscle fibres, and the expression of certain marker molecules. We tested if two of those markers, endothelin-1 (ET-1) and growth differentiation factor 15 (GDF-15), can be used as immunohistochemical markers for myocardial ischaemia/infarctions. The study included experiments with an animal model, the isolated perfused Langendorff heart, as well as the investigation of human tissue samples drawn during autopsies. The overall picture of our results showed that GDF-15 is very sensitive and expressed very fast, not only as a consequence of ischaemia/infarctions, but also under other circumstances...

Conceptualization of the ventricular system of the brain by macroscopic studies is complicated by the lack of physical structure of these interconnected cavities. Dissection procedures designed to display the structures in the walls of the ventricles are destructive and not conducive for the appreciation of the ventricular system in its entirety. The application of Micro-focus X-ray tomography affords the possibility to appreciate hidden structures in a non-destructive manner. The aim of this study was to explore the possibility of using micro-focus X-ray tomography in the three-dimensional (3D) visualization of the ventricular system as well as the various neuroanatomical structures within its walls for educational purposes...

In a reply to our letter Ferrandiz and colleagues wondered why dermoscopy experts did not already fully embrace teledermoscopy (TD) for suspicious pigmented skin lesions.(1) Our study showed that the structure of the health systems that were investigated differed, with countries where primary care physicians (PCP) hold a gate keeper function and others with direct access to a dermatologist. Significant differences in waiting time and travel distance were observed.(2) Since we believe that there is enough evidence that the addition of high quality dermoscopic pictures to a teleconsultation leads to higher accuracy of the diagnosis we did not investigate this question in our survey...

Intracellular signal mediator phosphatidylinositol-3-kinase (PIK3K) -δ, an isoform of PIK3K, is expressed in hematopoietic cells especially in lymphoid lineage 1. Idelalisib is a novel PIK3K-δ targeted kinase inhibitor which is approved for relapsed follicular B-cell non-Hodgkin lymphoma as a monotherapy and in combination with rituximab, an anti-CD20 antibody, for relapsed chronic lymphocytic leukemia (CLL) 2. Only one case describing the clinical features of severe cutaneous adverse reaction (SCAR) of idelalisib in detail has been previously published 3...

REVIEW
Scott W Burnside, Giles E Hardingham
Diverse neurodegenerative diseases share some common aspects to their pathology, with many showing evidence of disruption to the brain's numerous homeostatic processes. As such, imbalanced inflammatory status, glutamate dyshomeostasis, hypometabolism and oxidative stress are implicated in many disorders. That these pathological processes can influence each other both up- and downstream makes for a complicated picture, but means that successfully targeting one area may have an effect on others. This targeting requires an understanding of the mechanisms by which homeostasis is maintained during health, in order to uncover strategies to boost homeostasis in disease...

The picture of human immunodeficiency virus (HIV)-infected patients has changed dramatically since the original description in 1981. The introduction of antiretroviral drugs in 1987 and combination antiretroviral therapy has decreased mortality by as much as 80%. We now see patients in their 60s and 70s, having lived decades with HIV and living a normal live. As outlined in the article, despite good viral control, patients with HIV may present with solid organ cancers earlier than noninfected patients and are also prone to other complications of their disease that may require the attention of a thoracic surgeon...

BACKGROUND: Understanding intervention fidelity is an essential part of the evaluation of complex interventions because fidelity not only affects the validity of trial findings, but also because studies of fidelity can be used to identify barriers and facilitators to successful implementation, and so provide important information about factors likely to impact the uptake of the intervention into clinical practice. Participant observation methods have been identified as being particularly valuable in studies of fidelity, yet are rarely used...

Zhiye Tang, Chia-En A Chang
Understanding the fine balance between changes of entropy and enthalpy and the competition between a guest and water molecules in molecular binding is crucial in fundamental studies and practical applications. Experiments provide measurements. However, illustrating the binding/unbinding processes gives a complete picture of molecular recognition not directly available from experiments, and computational methods bridge the gaps. Here, we investigated guest association/dissociation with β-cyclodextrin (β-CD) by using microsecond-timescale molecular dynamics (MD) simulations, post-analysis and numerical calculations...

Dengue infections are among the most frequent causes of febrile disease in tropical climates. Infections are caused by a flavivirus transmitted by the Aedes mosquito. Aedes aegypti mosquitos are the main transmitters of Dengue viruses. Since these insects are both diurnal and container breeders, particular prevention and control measures are required. Symptom severity varies and can range from a mild, flu-like clinical picture to severe hemorrhage and shock. The most common symptoms experienced by travelers include fever, muscular pain, headaches and skin rash...

Metastasis accounts for a majority of cancer death. One key feature during metastasis is epithelial-mesenchymal transition (EMT), which is regulated by transcription factors such as Snail and Twist. In non-malignant cells, Snail has a short half-life and is degraded via ubiquitination, but its stability is increased in cancer cell. However, the mechanism by which Snail escapes ubiquitination and degradation remains unknown. Recently, we found that Dub3 is a deubiquinase of Snail. Most importantly, we determined that Dub3 responded to extracellular signals such as IL-6, and that the resultant signaling prevented Snail degradation, and promoted cancer growth, invasion, and migration...

While the usage of illicit drugs in itself carries significant health risks and associated toxicities, drugs that are adulterated to give them volume, alter their psychogenic properties, and make them cheaper to produce are to be considered even more dangerous. Cocaine is one of them, and it is now most commonly being adulterated with levamisole. We report a case of a 37-year-old female with the chief complaint of painful skin lesions and wounds on both of her upper and lower extremities for three weeks duration...

INTRODUCTION: The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herniate and become obstructed. This report describes 2 rare cases of small bowel occlusion owing to an internal hernia caused by a MDB...

Body dissatisfaction and depressive symptoms are commonly experienced during adolescence and increase the risk of adverse health outcomes, especially eating disorders. However, the dominant temporal associations between these two experiences (i.e., whether one is a risk factor for the other or the two are mutually reinforcing) has yet to be fully explored. We examined the associations between body dissatisfaction and depressive symptoms assessed at baseline and 5- and 10-year follow-up in younger (M age = 12...

Chronic uveitis is a common extra-articular manifestation of juvenile idiopathic arthritis. The classic clinical picture is one of chronic anterior uveitis, which usually remains asymptomatic until ocular complications arise. The risk of uveitis is increased in girls with an early onset of oligoarthritis and positive antinuclear antibodies. Even though the inflammation in patients with juvenile idiopathic arthritis is initially limited in the anterior part of the eye, chronic active inflammation may eventually cause significant damage to the posterior pole...

OBJECTIVE: Even though current policy is strongly focused on the crucial first '1000 days', it might be still possible to enhance cognitive function during the pre-adolescent and adolescent years by improving micronutrient status. In Cambodia, nutritional status is poor. Provision of rice fortified with micronutrients through a school meal programme (SMP) could be a cost-effective strategy to help improve health and school performance. The present study aimed to evaluate the effect of three different micronutrient-fortified rice formulations on cognitive function in Cambodian children...
