Ebola virus disease (EVD) is one of the deadliest viral diseases. It is characterized by a high mortality rate due to the lack of effective and safe treatments or vaccines and its ability to spread at an unstoppable pace. The West Africa outbreak ended but the disease may strike again at any time. The latest epidemic was, by far, the deadliest to date. The most concern was why this outbreak was so different from the previous ones. We proposed in this review firstly to summarize the principal causes of its unprecedented spread and secondly to identify the steps for an effective management approach of a future Ebola outbreak...

Immunoproteomics is become a potent methodology used for identifying immunoreactive proteins. In this study, an immunoproteomic approach based on 2-dimensional gel electrophoresis (2D-PAGE) and immunoblotting combined with high resolution mass spectrometry (MS) was used to identify immunoreactive proteins that might be involved in mechanisms of Guillain-Barré syndrome (GBS) development, regardless of their potential reciprocal molecular mimicry. Proteins isolated from C. jejuni and human peripheral nerve tissue (HPN) were separated with 2D SDS-PAGE and subjected to western blotting using serum samples from GBS patients...

Indigenous populations of the Americas experienced high mortality rates during the early contact period as a result of infectious diseases, many of which were introduced by Europeans. Most of the pathogenic agents that caused these outbreaks remain unknown. Through the introduction of a new metagenomic analysis tool called MALT, applied here to search for traces of ancient pathogen DNA, we were able to identify Salmonella enterica in individuals buried in an early contact era epidemic cemetery at Teposcolula-Yucundaa, Oaxaca in southern Mexico...

BACKGROUND: Interactions between societies and nature are regulated by complex systems of beliefs, symbolism, customs, and worldviews (kosmos), ecological knowledge (corpus), and management strategies and practices (praxis), which are constructed as product of experiences and communication of people throughout time. These aspects influence social relations, life strategies, and cultural identity, and all of them in turn influence and are influenced by local and regional patterns of interchange...

BACKGROUND: While emergency airway management training is conventionally conducted via face-to-face learning (F2FL) workshops, there are inherent cost, time, place and manpower limitations in running such workshops. Blended learning (BL) refers to the systematic integration of online and face-to-face learning aimed to facilitate complex thinking skills and flexible participation at a reduced financial, time and manpower cost. This study was conducted to evaluate its effectiveness in emergency airway management training...

Intratumor heterogeneity is a key factor contributing to therapeutic failure and, hence, cancer lethality. Heterogeneous tumors show partial therapy responses, allowing for the emergence of drug-resistant clones that often express high levels of the receptor tyrosine kinase AXL. In melanoma, AXL-high cells are resistant to MAPK pathway inhibitors, whereas AXL-low cells are sensitive to these inhibitors, rationalizing a differential therapeutic approach. We developed an antibody-drug conjugate, AXL-107-MMAE, comprising a human AXL antibody linked to the microtubule-disrupting agent monomethyl auristatin E...

BACKGROUND: Few studies have demonstrated detailed physical risk factors of hemorrhagic complications (HC) associated with the Angio-Seal closure device. This retrospective study aimed to identify the risk factors of HC due to Angio-Seal use. METHODS: Data from 143 cases that underwent neurointerventional procedures that involved puncturing the femoral artery and that used an Angio-Seal to close the puncture site were reviewed. We divided these cases into HC and no HC groups and retrospectively compared age, sex, past medical and preference history, body mass index (BMI), femoral artery depth, dual antiplatelet therapy use, activated clotting time, general anesthesia use, sheath size, right femoral artery puncture, and treatment time...

CONTEXT: Presbycusis, an age-related hearing impairment (ARHI), represents the most common sensory disability in adults. Today, the molecular mechanisms underlying presbycusis remain unclear. This is in particular due to the fact that ARHI is a multifactorial complex disorder resulting from several genomic factors interacting with lifelong cumulative effects of: disease, diet, and environment. OBJECTIVE: Identification of novel biomarkers for presbycusis. MATERIALS AND METHODS: We selectively ascertained eighteen elderly unrelated women lacking environmental and metabolic risk factors...

OBJECTIVE: To identify nurses' experiences of administering oral medications to residents of aged care facilities (ACFs) with swallowing difficulties. INTRODUCTION: Administering medicines to older people with swallowing difficulties is a challenging task. Nurses frequently modify oral medications e.g. by crushing/splitting tablets or opening capsules, to facilitate the administration process. These practices are associated with an increased risk of medication administration errors...

Mechanical conditioning is incompletely characterized for stimulating therapeutic cells within the physiological range. We sought to unravel the mechanism of action underlying mechanical conditioning of adipose tissue-derived progenitor cells (ATDPCs), both in vitro and in silico. Cardiac ATDPCs, grown on 3 different patterned surfaces, were mechanically stretched for 7 days at 1 Hz. A custom-designed, magnet-based, mechanical stimulator device was developed to apply ~10% mechanical stretching to monolayer cell cultures...

Biological changes occurring as a consequence of domestication and/or captivity are not still deeply known. In Atlantic salmon (Salmo salar), endangered (Southern Europe) populations are enhanced by supportive breeding, which involves only 6 months of captive rearing following artificial spawning of wild-collected adults. In this work, we assess whether several fitness-correlated life-history traits (migratory behavior, straying rate, age at maturity, and growth) are affected by early exposure to the captive environment within a generation, before reproduction thus before genetic selection...

Spaceflight impacts cardiovascular function in astronauts; however, its impact on cardiac development and the stem cells that form the basis for cardiac repair is unknown. Accordingly, further research is needed to uncover the potential relevance of such changes to human health. Using simulated microgravity (SMG) generated via two-dimensional clinorotation and culture aboard the International Space Station (ISS), we assessed the effects of mechanical unloading on human neonatal cardiovascular progenitor cell (CPC) developmental properties and signaling...

Cryptosporidium is an enteric parasite infecting a wide range of hosts. It has emerged as an important cause of chronic life-threatening diarrhea in humans worldwide. Several subtypes of Cryptosporidium sp. have been described to be responsible for several large outbreaks related to water contamination in developed countries. However, there is a lack of information in the genetic diversity of Cryptosporidium among human population especially in developing countries. The present study aimed to update and report the genetic diversity of human Cryptosporidium spp...

The mechanisms whereby monosodium urate (MSU) crystals deposition in gout activate nociceptors to induce joint pain are incompletely understood. We tried to reproduce the signs of painful gouty arthritis, injecting into the knee joint of rats suspensions containing amorphous or triclinic, needle MSU crystals. The magnitude of MSU-induced inflammation and pain behavior signs was correlated with the changes in firing frequency of spontaneous and movement-evoked nerve impulse activity recorded in single knee joint nociceptor saphenous nerve fibers...

Cerebellar granule cell precursors (GCPs) and granule cells (GCs) represent good models to study neuronal development. Here we report that the transcription factor, Meis1, plays pivotal roles to regulate mouse GC development. We found that Meis1 is expressed in granule cell lineage cells and astrocytes in the cerebellum during development. Targeted disruption of the Meis1 gene specifically in the GC lineage resulted in smaller cerebella with disorganized lobules. Knockdown/knockout experiments for Meis1 as well as in vitro assays show that Meis1 binds to an upstream sequence of Pax6 to enhance its transcription in GCPs/GCs and further suggested that the Meis1-Pax6 cascade regulates morphology of GCPs/GCs during development...
