Shear wave elastography (SWE) is an emerging technology that provides information about the inherent elasticity of tissues by producing an acoustic radiofrequency force impulse, sometimes called an "acoustic wind," which generates transversely-oriented shear waves that propagate through the surrounding tissue and provide biomechanical information about tissue quality. Although SWE has the potential to revolutionize bone and joint imaging, its clinical application has been hindered by technical and artifactual challenges...

BACKGROUND: Although all emergency departments (ED) should be ready to treat children, some may have illnesses or injuries that require higher-level pediatric resources that are not available at all hospitals. There are no national guidelines for EMS providers about when to directly transport children to hospitals with higher-level pediatric resources, with the exception of severe trauma. Variability exists in EMS protocols about when children warrant transport to hospitals with higher-level pediatric care...

The global burden of diabetes has drastically increased over the past decades and in 2017 approximately 4 million deaths were caused by diabetes and cardiovascular complications. Diabetic cardiomyopathy is a common complication of diabetes with early manifestations of diastolic dysfunction and left ventricular hypertrophy with subsequent progression to systolic dysfunction and ultimately heart failure. An in vitro model accurately recapitulating key processes of diabetic cardiomyopathy would provide a useful tool for investigations of underlying disease mechanisms to further our understanding of the disease and thereby potentially advance treatment strategies for patients...

PURPOSE: Psychoneurological (PN) symptoms, such as anxiety, cognitive impairment, depression, fatigue, sleep disturbances, and pain, are highly prevalent in breast cancer patients undergoing cancer treatment. Emerging evidence suggests that genetic polymorphisms may contribute to differential symptom susceptibility. We aimed to systematically review associations between genetic polymorphisms and PN symptoms during or after cancer treatment for early-stage breast cancer. METHODS: Twenty-six eligible articles published until October 2017 were identified in PubMed, PsycINFO, Web of Science, and additional records...

Exposure to electromagnetic radiation (EMR) is rapidly increasing in everyday environment, consequently conferring potential health effects. Oxidative stress is emerging as a mechanism implicated in pathophysiology and progression of various diseases. To our knowledge, no report has been made on the status of antioxidant redox systems after continuous exposure to radiofrequency radiation emitted from a Wi-Fi access point in animal model so far. Therefore, we aimed to continuously subject rats in the experimental group to radiofrequency (RF) radiation emitted from a commercially available Wi-Fi device...

Cerebellar Purkinje cells (PCs) are the sole output neurons of the cerebellar cortex, and damage to PCs results in motor deficits. Spinocerebellar ataxia type 3 (SCA3, also known as Machado-Joseph disease), a hereditary neurodegenerative disease, is caused by an abnormal expansion of the polyglutamine tract in the causative ATXN3 protein. SCA3 affects a wide range of cells in the central nervous system, including those in the cerebellum. To unravel SCA3 pathology, we used adeno-associated virus serotype 9 (AAV9) vectors to express full-length ATXN3 with an abnormally expanded 89 polyglutamine stretch (ATXN3[Q89]) in cerebellar neurons of mature wild-type mice...

CH functionalization is an attractive strategy to construct and diversify molecules. Heme proteins, predominantly cytochromes P450, are responsible for an array of CH oxidations in biology. Recent work has coupled concepts from synthetic chemistry, computation, and natural product biosynthesis to engineer heme protein systems to deliver products with tailored oxidation patterns. Heme protein catalysis has been shown to go well beyond these native reactions and now accesses new-to-nature CH transformations, including CN and CC bond forming processes...

Since the beginning of the last century, substantial evidence has suggested that various aspects of the immune system are influenced by the activity of the nervous system. However, the cellular and molecular basis for the neural control of immune responses has emerged only in the past decade. Recent studies have shown that adrenergic nerves control trafficking of immune cells through cell-type-specific mechanisms. Activation of the β2 -adrenergic receptor expressed on lymphocytes enhances signals mediated by a particular set of chemokine receptors, and consequently inhibits their exit from lymph nodes...

BACKGROUND: Bacteroides spp., an anaerobic resident intestinal flora is also known to cause severe morbidity. They are resistant to a wide variety of antimicrobial agents including metronidazole. Specific nitroimidazole (nim) resistance genes have been shown to be associated with the same. Worldwide, metronidazole resistance is emerging, though presently remains around 5%. This study was aimed at metronidazole susceptibility and distribution of nim genes within the Bacteroides spp. We also analyzed the relationship among the strains harboring nim genes and their susceptibility to metronidazole...

Ferret and mink coronaviruses typically cause catarrhal diarrhea in ferrets and minks, respectively. In recent years, however, systemic fatal coronavirus infection has emerged in ferrets, which resembles feline infectious peritonitis (FIP) in cats. FIP is a highly fatal systemic disease caused by a virulent feline coronavirus infection in cats. Despite the importance of coronavirus infections in these animals, there are no effective commercial vaccines or antiviral drugs available for these infections. We have previously reported the efficacy of a protease inhibitor in cats with FIP, demonstrating that a virally encoded 3C-like protease (3CLpro) is a valid target for antiviral drug development for coronavirus infections...

The ubiquitin proteasome system (UPS) is the major pathway for intracellular protein degradation in most organs, including the heart. UPS controls many fundamental biological processes such as cell cycle, cell division, immune responses, antigen presentation, apoptosis, and cell signaling. The UPS not only degrades substrates but also regulates activity of gene transcription at the post-transcription level. Emerging evidence suggests that impairment of UPS function is sufficient to cause a number of cardiac diseases, including heart failure, cardiomyopathies, hypertrophy, atrophy, ischemia-reperfusion, and atherosclerosis...

In the last few years, immunotherapy has revolutionized the oncology landscape by targeting the host immune system. Blocking immune checkpoints such as cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), programmed cell death-1 (PD-1) and its ligand (PD-L1 or B7-H1), has proven its efficacy in several solid cancers. Recently, several clinical studies have demonstrated a significant improvement in clinical response to the anti-PD-1-based immunotherapy in a subset of patients with microsatellite instability-high (MSI-H)/mismatch repair (MMR)-deficient tumors that accumulate short insertion/deletion mutations notably in coding microsatellites regions of the genome...

OBJECTIVE: Scorpion stings remain a serious health problem in many parts of the world. There is very limited information regarding the effects of therapies delivered for scorpion stings in pregnant women on the mother and fetus. They can cause acute conditions such as fetal loss, preterm delivery, or placental abnormalities and can also result in other conditions that may have an effect on the baby in the long term. MATERIALS AND METHODS: In this study the medical records of 24 pregnant women who were admitted to the emergency room at Suruç State Hospital due to scorpion stings between January 1, 2013 and January 1, 2014 were retrospectively reviewed...

Systemic diseases commonly managed by the Internist may have presentations within the head and neck. Awareness of these manifestations, sometimes as the presenting signs or symptoms of systemic disease, may aid the Internist in diagnosis and management. The Otolaryngologist may be helpful in assisting in the evaluation of these patients and in some cases providing targeted symptomatic therapy. Some systemic processes can generate emergent airway events, and early engagement of the otolaryngologist is of value...

Long noncoding RNAs (lncRNAs) are endogenous RNA transcripts longer than 200 nucleotides which regulate epigenetically the expression of genes but do not have protein-coding potential. They are emerging as potential key regulators of diabetes mellitus and a variety of cardiovascular diseases. Diabetic cardiomyopathy (DCM) refers to diabetes mellitus-elicited structural and functional abnormalities of the myocardium, beyond that caused by ischemia or hypertension. The purpose of this review was to summarize current status of lncRNA research for DCM and discuss the challenges and possible strategies of lncRNA research for DCM...

Magic-angle-spinning (MAS) dynamic nuclear polarization (DNP) has recently emerged as a powerful technology enabling otherwise unrealistic solid-state NMR experiments. The simulation of DNP processes which might, for example, aid in refining the experimental conditions or the design of better performing polarizing agents, is, however, plagued with significant challenges, often limiting the system size to only 3 spins. Here, we present the first approach to fully ab initio large-scale simulations of MAS DNP enhancements...

Current drug therapy against infections is threatening to become obsolete due to the poor physical, chemical, biological and pharmacokinetic properties of drugs, followed by high risk of acquiring resistance. Taking into account the significant benefits of nanotechnology, nano-based delivery of anti-infectious agents is emerging as a potential approach to combat several lethal infections. Co-delivery of multiple anti-infectious agents in a single nano-based system is beginning to show significant advantages over mono-therapy, such as synergism, enhanced anti-microbial activity, broad anti-microbial spectrum, reduced resistance development, and improved and cost-effective treatment...
