BACKGROUND AND OBJECTIVE: Non-invasive ventilation (NIV) improves clinical outcomes in hypercapnic acute exacerbations of COPD (AECOPD), but the optimal model of care remains unknown. METHODS: We conducted a prospective observational non-inferiority study comparing three models of NIV care: general ward (Ward) (1:4 nurse to patient ratio, thrice weekly consultant ward round), a high dependency unit (HDU) (1:2 ratio, twice daily ward round) and an intensive care unit (ICU) (1:1 ratio, twice daily ward round) model in three similar teaching tertiary hospitals...

AIM: Premature birth is an extremely stressful experience. In 2013 to 2014 we explored the physiological stress responses of fathers during their first skin-to-skin contact with their new baby. METHODS: We recruited 49 fathers whose partners had given birth to a premature baby of up to 33 weeks and three days. The study, in the neonatal intensive care unit (NICU) of a Quebec hospital, measured the physiological stress responses of the fathers before and after they first experienced skin-to-skin contact with their new baby...

Chediak-Higashi syndrome (CHS) belongs to a group of partial oculocutaneous albinism and immunodeficiency. Five autosomal recessive conditions are recognized in this group, characterized by hypopigmentation of hair, skin and eyes, associated with recurrent infections. Additionally CHS can present coagulopathies, neurological dysfunction and large granules in many cell types. This article is protected by copyright. All rights reserved.

A prospective study of non-invasive ventilation at The Prince Charles Hospital outside of the intensive care unit from March 2015 to March 2016 was performed. Overall 69 patients were included. Acute hypercapnic respiratory failure was the most common indication (n = 59; 85%). 49 (71%) had multifactorial respiratory failure. 15 (22%) patients died. Premorbid inability to perform self-care (P = 0.001) and the combination of mean pH < 7.25 and mean PaCO2 ≥ 75 mmHg within 2 h of NIV initiation (P = 0.037) were significantly associated with mortality...

Salmonid alphaviruses (SAV) severely infects farmed salmonids and rainbow trout. Owing to the recent increase in fish import trade, several SAV-unreported countries, such as China, may face serious threat of this infection. Thus, it is necessary to develop efficient detection methods for the prevention and diagnosis of SAV infection. In this study, we selected a conserved segment of the SAV E1 protein as a target immunogen for the preparation of monoclonal antibodies (mAbs) specific to SAV. A sensitive indirect immunofluorescence (IF) method was developed using 26E9C2 mAb that detected E1 protein and identified subtypes 1, 2 and 5 of SAV...

In the present study, we isolated twenty eight yeast strains from samples of plant material and fermented food and evaluated the possibility of efficient production of 2-phenylethanol (2-PE) in the organic waste-based media supplemented with L-phenylalanine (L-Phe). We used whey, a by-product from milk processing, as a base for media and either glucose or three by-products from sugar-beet processing as a fermentable carbon source. Ten newly isolated yeast strains were capable of producing over 2 g l-1 2-PE through the L-Phe biotransformation in a batch-mode in standard medium...

AIM/HYPOTHESIS: Adiponectin (APN), a circulating hormone secreted by mature adipocytes, has been extensively studied because it has beneficial metabolic effects. While many studies have focused on the congenital loss of APN and its effects on systemic body glucose and lipid metabolism, little is known about the effects triggered by acute loss of APN in the adult mouse. We anticipated that genetically induced acute depletion of APN in adult mice would have a more profound effect on systemic metabolic health than congenital deletion of Adipoq, the gene encoding APN, with its associated potential for adaptive responses that may mask the phenotypes...

In folklore medicine, the plant Emilia sonchifolia, belonging to the family Asteraceae, is used for treating tumour and inflammation. In our previous studies, we have done a thorough phytochemical investigation of E. sonchifolia with a report on its potent antimetastatic activity. Further, we isolated and characterised its active fraction (AFES) containing the major compound γ-humulene with an evaluation of the antiangiogenic effect of AFES (5 mg/kg b.wt.). In the first part of the present study, AFES in different concentrations was used for the assessment of its possible anti-inflammatory effect employing three in vivo inflammatory models...

Four soybean storage protein subunit QTLs were mapped using bulked segregant analysis and an F2 population, which were validated with an F5 RIL population. The storage protein globulins β-conglycinin (7S subunit) and glycinin (11S subunits) can affect the quantity and quality of proteins found in soybean seeds and account for more than 70% of the total soybean protein. Manipulating the storage protein subunits to enhance soymeal nutrition and for desirable tofu manufacturing characteristics are two end-use quality goals in soybean breeding programs...

Over the last few years a number of restriction enzymes that cut DNA only if cytosines within their recognition sequences are methylated have been characterized and become commercially available. Cleavage with these enzymes to release DNA fragments in a methylation-dependent manner can be combined with a novel method of amplification, Helper Dependent Chain Reaction (HDCR), to selectively amplify these fragments. HDCR uses "Helper" oligonucleotides as templates for extension of the free 3' end of target fragments to incorporate tag sequences at the ends of fragments...

Cytosine methylation has been shown to have a role in a host of biological processes. In mammalian biology these include stem cell differentiation, embryonic development, genomic imprinting, inflammation, and silencing of transposable elements. Given the central importance of these processes, it is not surprising to find aberrant cytosine methylation patterns associated with many disorders in humans, including cancer, cardiovascular disease, and neurological disease. While whole genome shotgun bisulfite sequencing (WGBS) has recently become feasible, generating high sequence coverage data for the entire genome is expensive, both in terms of money and analysis time, when generally only a small subset of the genome is of interest to most researchers...

Epigenetic regulation plays a critical role in gene expression, cellular differentiation, and disease. There is a complex interplay between the different layers of epigenetic information, including DNA methylation, nucleosome positions, histone modifications, histone variants, and other important epigenetic regulators. The different modifications do not act independently of each other and their relationship plays an important role in governing the regulation of the epigenome. Of these, DNA methylation is the best-studied epigenetic modification in mammals...

PURPOSE: Ferritin is an intracellular iron storage protein and a marker of inflammation. Studies have shown that subjects with obstructive sleep apnea (OSA) have higher levels of circulating pro-inflammatory cytokines, but little is known about the association between ferritin and OSA. The aims of the study were to evaluate serum ferritin (S-Ferritin) levels in OSA patients compared to levels in the general population and also examine the effect of obesity level and treatment with positive airway pressure (PAP) on S-Ferritin levels...

AIMS: Mild-to-moderate hypoglycemia (blood glucose < 4.0 mmol/L) is recommended to be treated with 15 g of carbohydrates and to repeat the treatment if hypoglycemia persists after 15 min. This recommendation was established before intensive insulin therapy and based on studies using insulin with different pharmacokinetic profiles from actual insulin analogs showing that 15 g of glucose increases blood glucose by ~ 1.5 mmol/L in 15 min. We aimed to explore the effect of current recommended treatment of mild-to-moderate hypoglycemia in type 1 diabetes (T1D) participants and factors associated with treatment effectiveness...

A new begomovirus species was identified from tomato plants with upward leaf curling and purple vein symptoms, which was first identified in the Piaui state of Northeast (NE) Brazil in 2014. Tomato leaf samples were collected in 2014 and 2016, and PCR with degenerate primers revealed begomovirus infection. Rolling circle amplification and restriction enzyme digestion indicated a single genomic DNA of ~ 2.6 kb. Cloning and sequencing revealed a genome organization similar to DNA-A components of New World (NW) bipartite begomoviruses, with no DNA-B...

In order to evaluate the enhancement mechanisms of enhanced startup performance in biofilm systems for polluted source water pretreatment, three lab-scale reactors with elastic stereo media (ESM) were operated under different enhanced sediment and hydraulic agitation conditions. It is interesting to found the previously underestimated or overlooked effects of sediment on the enhancement of pollutants removal performance and enrichment of functional bacteria in biofilm systems. The maximum NH4+-N removal rate of 0...

BACKGROUND: Spontaneous cervical artery dissections (sCAD) are often preceded by infections. However, existing data about inflammatory parameters remained inconsistent. Remarkably, concurrent information about the coagulation system, whose affection seems also reasonable to cause ischaemic events, are still lacking in sCAD patients. Thus, this study explores the association between the inflammatory and coagulation system in patients with sCAD. METHODS: The parameters leukocyte and thrombocyte count, C-reactive protein, fibrinogen, D-dimer, activated partial thromboplastin time (aPTT) and prothrombin time were extracted from hospital-based medical records of patients (n = 60) with sCAD and compared with those of a control group (n = 97) from a prospective observational stroke study...

To advance predictive ecology, the hypothesis of hierarchical predictability proposes that community measures for which species are interchangeable (e.g., structure and species richness) are more predictable than measures for which species identity matters (e.g., community composition). Predictability is hypothesized to decrease for response measures in order of the following categories: structure, species richness, function, and species composition. We tested this hypothesis using a 14-year, oak savanna-prairie restoration experiment that removed non-native pine plantations at 24 sites in northwestern Ohio, USA...

Aneurysmal subarachnoid hemorrhage (aSAH) is associated with high socio-economic burden. Prothrombotic states of early brain injury (EBI) and delayed cerebral ischemia (DCI) after aSAH determine morbidity and mortality. To understand how activated platelets might contribute to such prothrombotic states, we studied trends in coated-platelets during EBI and DCI periods. Serial blood samples from a prospective cohort of aSAH patients were collected and assayed for coated-platelet levels. Patient's coated-platelet level during post-hospital discharge follow-up served as an estimate of baseline...

Women in the modern era are challenged with facing menopausal symptoms as well as heightened disease risk associated with increasing adiposity and metabolic dysfunction for up to three decades of life. Treatment strategies to combat metabolic dysfunction and associated pathologies have been hampered by our lack of understanding regarding the biological causes of these clinical conditions and our incomplete understanding regarding the effects of estrogens and the tissue-specific functions and molecular actions of its receptors...
