BACKGROUND: Observational data have described the association of blood pressure (BP) with mortality as 'J-shaped', meaning that mortality rates increase below a certain BP threshold. We aimed to analyse the associations between BP and prognosis in a population of acute myocardial infarction (MI) patients with heart failure (HF) and/or systolic dysfunction. METHODS AND RESULTS: The datasets included in this pooling initiative are derived from four trials: CAPRICORN, EPHESUS, OPTIMAAL, and VALIANT...

Background Sporadic arteriovenous malformations of the brain, which are morphologically abnormal connections between arteries and veins in the brain vasculature, are a leading cause of hemorrhagic stroke in young adults and children. The genetic cause of this rare focal disorder is unknown. Methods We analyzed tissue and blood samples from patients with arteriovenous malformations of the brain to detect somatic mutations. We performed exome DNA sequencing of tissue samples of arteriovenous malformations of the brain from 26 patients in the main study group and of paired blood samples from 17 of those patients...

Adjuvants have a critical role for improving vaccine efficacy against many pathogens, including HIV. Here, using transcriptional RNA profiling and systems serology, we assessed how distinct innate pathways altered HIV-specific antibody responses in nonhuman primates (NHPs) using 8 clinically based adjuvants. NHPs were immunized with a glycoprotein 140 HIV envelope protein (Env) and insoluble aluminum salts (alum), MF59, or adjuvant nanoemulsion (ANE) coformulated with or without Toll-like receptor 4 (TLR4) and 7 agonists...

AIM: To evaluate the efficacy and safety of neuromultivit (valiant, Russia) as add-on to the basic therapy of vertebrogenic radiculopathy (VR) L5-S1. MATERIAL AND METHODS: The open clinical trial included 100 patients with VR L5-S1 randomized into 2 groups. In group 1, patients received neuromultivit and basic therapy; in group 2 only basic therapy. Treatment efficacy was assessed by the dynamics of regression of pain intensity on the visual analogue scale (VAS), McGill pain questionnaire (MGPQ), Aberdeen back pain scale (ABPS), the Quebec Back Pain Disability Scale (QBPDS), the dynamics of neurologic symptoms, the need for additional treatment with NSAID...

Mutations of SLC40A1 encoding ferroportin (Fpn), the unique cellular iron exporter, severely affect iron homeostasis causing type 4 hereditary hemochromatosis, an autosomal dominant iron overload condition with variable phenotypic manifestations. This disease can be classified as type 4A, better known as "ferroportin disease", which is due to "loss of function" mutations that lead to decreased iron export from cells, or as type 4B hemochromatosis, which is caused by "gain of function" mutations, conferring partial or complete resistance to hepcidin-mediated Fpn degradation...

Jaime Gómez-Ramírez, Shelagh Freedman, Diego Mateos, José Luis Pérez Velázquez, Taufik Valiante
This paper addresses a fundamental question, are eyes closed and eyes open resting states equivalent baseline conditions, or do they have consistently different electrophysiological signatures? We compare the functional connectivity patterns in an eyes closed resting state with an eyes open resting state to investigate the alpha desynchronization hypothesis. The change in functional connectivity from eyes closed to eyes open, is here, for the first time, studied with intracranial recordings. We perform network connectivity analysis in iEEG and we find that phase-based connectivity is sensitive to the transition from eyes closed to eyes open only in interhemispheral and frontal electrodes...

Sarah Voll, Taufik A Valiante
We expand on the discourse related to nature surrounding Canadian medical training and the CanMEDS flower. We advance the notion that a major contributor to burnout is the increasing complexity and segregation of not only the medical profession, but society as a whole, leading to choice overload and an overemphasis on complex, data driven, rational decision making. We then propose that the key to watering CanMEDS flowers and preventing physician burnout lies in getting back to the basics of human behaviour.

Filamentous fungi produce numerous high-value natural products (NPs). The biosynthetic genes for NPs are normally clustered in the genome. A valuable NP class is represented by the insecticidal austinoids. We previously determined their biosynthesis in the fungus Aspergillus calidoustus. After further computational analysis looking into the austinoid gene clusters in two additional distantly related fungi, Aspergillus nidulans and Penicillium brasilianum, a rearrangement of the genes was observed that corresponded to the diverse austinoid derivatives produced by each strain...

Gerard O'Leary, Taufik A Valiante, Roman Genov
Growing evidence suggests that cross-frequency coupling (CFC) is a key mechanism in neuronal computation, communication, and learning in the brain. Abnormal CFC has been implicated in pathological brain states such as epilepsy and Parkinson's disease. A reduction in excessive coupling has been shown in effective neuromodulation treatments, suggesting that CFC may be a useful feedback measure in closed-loop neural stimulation devices. However, processing latency limits the responsiveness of such systems. A VLSI architecture is presented which implements three selectable measures of CFC to enable the application specific trade-off between low-latency and high-accuracy processing...

Infection in humans with Leishmania manifests into a spectrum of diseases. The manifestations of the disease depend on the resultant evasion of the parasite to immune responses namely macrophages, which is an exclusive host of leishmania. The B cells valiantly mount antibody responses, however to no avail as the Leishmania parasites occupy the intracellular niches of the macrophages. Extensive studies have been documented on the role of cell-mediated immunity (CMI) in protection and counter survival strategies of the parasites leading to down-regulation of CMI...

Activation of γ-aminobutyric acid (GABAA) receptors have been associated with the onset of epileptiform events. To investigate if a causal relationship exists between GABAA receptor activation and ictal event onset, we activated inhibitory GABAergic networks in the superficial layer (2/3) of the somatosensory cortex during hyperexcitable conditions using optogenetic techniques in mice expressing channelrhodopsin-2 in all GABAergic interneurons. We found that a brief 30ms light pulse reliably triggered either an interictal-like event (IIE) or ictal-like ("ictal") event in the in vitro cortical 4-Aminopyridine (4-AP) slice model...

OBJECTIVES: Thoracic endovascular aortic repair (TEVAR) has been shown to lead to increased aortic stiffness. The aim of this study was to investigate the effect of stent graft type and stent graft length on aortic stiffness in a controlled, experimental setting. METHODS: Twenty porcine thoracic aortas were connected to a pulsatile mock loop system. Intraluminal pressure was recorded at two sites in order to measure pulse wave velocity (PWV) for each aorta: before stent graft deployment (t1); after deployment of a 100-mm long stent graft (t2); and after distal extension through deployment of a second 100-mm long stent graft (t3)...

BACKGROUND: Heart rate has been reported to be associated with adverse outcome in heart failure (HF) and myocardial infarction (MI), but conflicting evidence exists regarding its impact in patients with associated atrial fibrillation (AF). OBJECTIVES: We investigated the differential impact of heart rate on clinical outcomes according to the presence or absence of AF in patients with reduced systolic function and/or HF after MI. METHODS: We studied the association of heart rate with outcome using Cox-models in a merged dataset (n=28,771) of four randomized trials (CAPRICORN, EPHESUS, OPTIMAAL, and VALIANT)...

Dibutylphthalate (DBP) is an environmental pollutant widely used as plasticizer in a variety of industrial applications worldwide. This agent can be found in personal-care products, children's toy, pharmaceuticals, food products. Exposure to DBP can occur via ingestion and inhalation as well as intravenous or skin contact. DBP belongs to the family of endocrine disrupting chemicals (EDCs) and its effects on reproductive system were demonstrated both in vivo and in vitro. In the present study we evaluated the effects of DBP on human prostate adenocarcinoma epithelial cells (LNCaP) in order to highlight xenoestrogens influence on human prostate...

Structural and functional homologies between the Zika and Dengue viruses' envelope proteins raise the possibility that cross-reactive antibodies induced following Zika virus infection might enhance subsequent Dengue infection. Using the rhesus macaque model we show that prior infection with Zika virus leads to a significant enhancement of Dengue-2 viremia that is accompanied by neutropenia, lympocytosis, hyperglycemia, and higher reticulocyte counts, along with the activation of pro-inflammatory monocyte subsets and release of inflammatory mediators...

Following epilepsy surgery, a good psychosocial outcome is not necessarily contingent on a good seizure outcome. Increasingly, it is believed that "successful" surgery is a combination of both an acceptable and expected seizure status as well as the individual's perception of improvements in quality of life (QOL). The factors that create this optimal outcome remain an ongoing area of research in the epilepsy community. That being said, there have been some major breakthroughs in observing and understanding poor outcomes seen in a subset of postoperative patients with epilepsy...

gH625 constitutes a promising delivery vehicle for the transport of therapeutic biomacromolecules across membrane barriers. We report an application of multivalency to create a complex nanosystem for delivery and to elucidate the mechanism of peptide-lipid bilayer interactions. Multivalency may offer a route to enhance gH625 cellular uptake as demonstrated by results obtained on dimers of gH625 by fluorescence spectroscopy, circular dichroism, and surface plasmon resonance. Moreover, using both phase contrast and light sheet fluorescence microscopy we were able to characterize and visualize for the first time the fusion of giant unilamellar vesicles caused by a membranotropic peptide...
