Dengue is a major global disease requiring improved treatment and prevention strategies. The recently licensed Sanofi-Pasteur Denvaxia vaccine does not protect children under the age of nine and additional vaccine strategies are thus needed to halt this expanding global epidemic. Here, we employed a molecular engineering approach and plant-expression to produce a humanised and highly immunogenic Poly-Immunoglobulin G Scaffold (PIGS) fused to the consensus dengue envelope protein III domain (cEDIII). The immunogenicity of this IgG Fc receptor targeted vaccine candidate was demonstrated in transgenic mice expressing human FcγRI/CD64, by induction of neutralising antibodies and evidence of cell-mediated immunity...

BACKGROUND AND OBJECTIVES: Human milk has nutritional, protective, and developmental advantages for premature infants. However, proteomic information of low abundant protein of donor milk is insufficient. The purpose of this study is to analyze and compare the proteome of low abundant protein of donor milk obtained at different postpartum ages other than the colostrum. METHODS AND STUDY DESIGN: Donor breast milk from 12 healthy mothers was collected 15 days, 2 months and 6 months after delivery and stored by medically approved methods...

Tau misfolding is a major cause of neurodegeneration, tauopathies being a growing group of diseases in which tau forms insoluble aggregates, best known in Alzheimer disease as neurofibrillary tangles (NFTs). Many transgenic mouse models of tauopathies have been generated, but it has been difficult to demonstrate disease in primary brain neurons from these mice because neurons need to be harvested within a few days of birth and tau fails to produce NFTs. Transgenic mice have been generated that express the 0N4R isoform of human tau mutated at amino acid 301 (P301S mice) under the Thy1...

Butyricicoccus pullicaecorum and Megasphaera elsdenii inhabit the human intestine and have probiotic potential. The aim of this study was to evaluate the effects of B. pullicaecorum and M. elsdenii on the lifespan of Caenorhabditis elegans. They significantly (P < 0.05) extended the lifespan of C. elegans compared with Escherichia coli OP50, a standard food for the worm. Analysis of age-related biomarkers such as lipofuscin, body size, and locomotory activity showed that they retarded aging. They all failed to extend the lifespan of daf-12 or dbl-1 loss-of-function C...

To understand the prenatal origin of developmental and psychiatric disorders, studies in laboratory animals are imperative. However, the developmental pace differs between humans and animals; hence, corresponding human ages must be estimated to infer the most vulnerable developmental timings in humans. Because rats and mice are extensively used as models in developmental research, a correspondence between human foetal ages and rodents' ages must be precisely determined; thus, developing a translational model is of utmost importance...

Concurrent with the development of recombinant factor replacement products, the characterization of the F9 and F8 genes over 3 decades ago allowed for the development of recombinant factor products and made the hemophilias a target disease for gene transfer. The progress of hemophilia gene therapy has been announced in 3 American Society of Hematology scientific plenary sessions, including the first "cure" in a large animal model of hemophilia B in 1998, first in human sustained vector-derived factor IX activity in 2011, and our clinical trial results reporting sustained vector-derived factor IX activity well into the mild or normal range in 2016...

BACKGROUND: Because gait performance is a marker of organic integrity, and the Human Development Index (HDI) of a region impacts the organism globally, this paper aims to investigate possible associations between both HDI and HDI dimensions at individual level (i.e. education, income, or life expectancy) with gait performance in older adults. METHODS: Searches were conducted on EMBASE and PubMed databases. Eligible studies included community-dwelling population aged ≥60years, analysis of at least one quantitative gait variable, observational studies, Human Development Index or its dimensions (i...

C-C chemokine receptor type 5 (CCR5) is a chemokine receptor that influences the immune response to infectious and parasitic diseases. This study aimed to determine whether the CCR5Δ32 and CCR5 59029 A/G polymorphisms are associated with the development of ocular toxoplasmosis in humans. Patients with positive serology for Toxoplasma gondii were analyzed and grouped as 'with ocular toxoplasmosis' (G1: n=160) or 'without ocular toxoplasmosis' (G2: n=160). A control group (G3) consisted of 160 individuals with negative serology...

BACKGROUND: Venovenous extracorporeal membrane oxygenation (VV-ECMO) is a valuable life support in acute respiratory distress syndrome (ARDS) in adult patients. However, the success of VV-ECMO is known to be influenced by the baseline settings of mechanical ventilation (MV) before its institution. This study was aimed at identifying the baseline ventilator parameters which were independently associated with hospital mortality in non-trauma patients receiving VV-ECMO for severe ARDS. METHODS: This retrospective study included 106 non-trauma patients (mean age: 53 years) who received VV-ECMO for ARDS in a single medical center from 2007 to 2016...

BACKGROUND: As the practice of medicine inevitably raises both ethical and legal issues, it had been recommended since 1999 that medical ethics and human rights be taught at every medical school. Most Nigerian medical schools still lack a formal undergraduate medical ethics curriculum. Medical education remains largely focused on traditional medical science components, leaving the medical students to develop medical ethical decision-making skills and moral attitudes passively within institutions noted for relatively strong paternalistic traditions...

BACKGROUND: A recent publication suggested molecular mimicry of a nucleoprotein (NP) sequence from A/Puerto Rico/8/1934 (PR8) strain, the backbone used in the construction of the reassortant strain X-179A that was used in Pandemrix® vaccine, and reported on anti-hypocretin (HCRT) receptor 2 (anti-HCRTR2) autoantibodies in narcolepsy, mostly in post Pandemrix® narcolepsy cases (17 of 20 sera). In this study, we re-examined this hypothesis through mass spectrometry (MS) characterization of Pandemrix®, and two other pandemic H1N1 (pH1N1)-2009 vaccines, Arepanrix® and Focetria®, and analyzed anti-HCRTR2 autoantibodies in narcolepsy patients and controls using three independent strategies...
