Jimmy Hu, Phillip Cantrell, Aklesh Nand
Urethane products that contain isocyanates are extensively used in the motor vehicle repair (MVR) industry and other industries such as furniture and cabinet-making as two-pack spray paints, clears, and adhesives. Attention has recently been refocussed on isocyanate-containing chemicals, particularly in paints. The spray painters in the MVR industry had a propensity to develop industrial asthma at a rate 80 times higher than the general public, which was previously reported in the UK. To track workers exposure to isocyanates, urine samples were collected from 196 spray painters who worked mainly in 78 MVR shops across 54 New South Wales (NSW) towns and suburbs...

Cinnamaldehyde amino acid Schiff base (CAAS) is a new class of safe, bioactive compounds which could be developed as potential antifungal agents for fungal infections. To design new cinnamaldehyde amino acid Schiff base compounds with high bioactivity, the quantitative structure-activity relationships (QSARs) for CAAS compounds against Aspergillus niger (A. niger) and Penicillium citrinum (P. citrinum) were analysed. The QSAR models (R(2) = 0.9346 for A. niger, R(2) = 0.9590 for P. citrinum,) were constructed and validated...

Doxorubicin (DOX) is an effective anticancer drug. But its clinical application is limited, because DOX induces apoptosis in cardiomyocytes and it leads to permanent degenerative cardiomyopathy and heart failure. Recent trainings showed that Hibiscus sabdariffa exhibit pharmacological actions such as potent antioxidant. So, in this study we explored the protective effect of H. sabdariffa extract on doxorubicin-induced cytotoxicity in H9c2 cells. Cell viability was quantified by MTT assay. Apoptotic cells were determined using PI staining of DNA fragmentation by flowcytometry (sub-G1 peak)...

In the general population, physical activity is associated with improved health outcomes. However, long-term sports participation may be associated with adverse outcomes, particularly at the elite level. The aims of this study were to assess morbidity and health-related quality of life (HrQoL) amongst former rugby players, compared to an age-standardised general population sample. A cross-sectional study of former elite, male, rugby players (n = 259) was undertaken, and standardised morbidity ratios (SMR) calculated, assessing morbidity prevalence relative to English Longitudinal Study of Aging participants (ELSA, n = 5186)...

Herpes simplex encephalitis (HSE) is associated with significant mortality and morbidity. As a consequence of HSE, up to 75% of infected individuals die or experience irreversible neurological damage. While the pathogenesis of the disease is unknown, it is traditionally hypothesized that the viral infection occurs by neuronal transmission directly from peripheral sites. Non-neuronal modes of infection have generally been overlooked as the brain is protected by the blood-brain-barrier (BBB). The BBB poses an effective barrier to pathogens as well as to drugs such as chemotherapies...

Hepatitis A is an acute viral infection of the liver that produces clinical features ranging from asymptomatic infection to fulminant hepatitis(1). The authors report a cluster of 5 serologically-confirmed cases of acute Hepatitis A Virus (HAV), all serum IgM positive for HAV Genotype 1A. This is on a background of only 2 other cases notified to HSE-South in 2016 to date, both travel related. There was a considerable delay in notification in two out of 5 cases. This case report highlights the importance of prompt notification of Hepatitis A, as timely notification would have facilitated prompt contact vaccination and might well have prevented illness in two subsequent household contacts...

The Irish National Consent Policy (NCP) proposes that the legal requirement for consent extends to all forms of interventions, investigations and treatment, carried out on or behalf of the Health Service Executive (HSE). This study employs a quantitative descriptive approach to investigate the practices for obtaining consent for an identified group of routine neonatal procedures in neonatal facilities throughout Ireland. The BAPM (British Association of Perinatal Medicine) guidelines were identified as 'gold standard' for the purposes of this study...

The requirement for organisations to co-operate regarding doses to staff who work across organisational boundaries is well established. However, in the field of personal dosimetry there is little guidance as to how to actually achieve legal compliance. Following improvement action in the UK by the regulator, The Health & Safety Executive, a guidance document was developed by the leading professional bodies in this area. This guidance was also commented on by the HSE Specialist Inspectorate (Radiation) enabling the published guidance to represent a compliant standard...

The birth of novel genes, including their cell-specific transcriptional control, is a major source of evolutionary innovation. The lens-preferred proteins, crystallins (vertebrates: α- and β/γ-crystallins), provide a gateway to study eye evolution. Diversity of crystallins was thought to originate from convergent evolution through multiple, independent formation of Pax6/PaxB-binding sites within the promoters of genes able to act as crystallins. Here, we propose that αB-crystallin arose from a duplication of small heat shock protein (Hspb1-like) gene accompanied by Pax6-site and heat shock element (HSE) formation, followed by another duplication to generate the αA-crystallin gene in which HSE was converted into another Pax6-binding site...

Obesity is a major public health problem. Herein, we aim to identify the correlation between brain circuit segregation and obesity using multimodal functional magnetic resonance imaging (fMRI) techniques and analysis. Twenty obese patients (BMI=37.66±5.07) and 30 healthy controls (BMI=22.64±3.45) were compared using neuroimaging and assessed for symptoms of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). All participants underwent resting-state fMRI (rs-fMRI) and T1-weighted imaging using a 1...

BACKGROUND: The global economic crisis saw recessionary conditions in most EU countries. Ireland's severe recession produced pro-cyclical health spending cuts. Yet, human resources for health (HRH) are the most critical of inputs into a health system and an important economic driver. The aim of this article is to evaluate how the Irish health system coped with austerity in relation to HRH and whether austerity allowed and/or facilitated the implementation of HRH policy. METHODS: The authors employed a quantitative longitudinal trend analysis over the period 2008 to 2014 with Health Service Executive (HSE) staff database as the principal source...

BACKGROUND: Standard two-dimensional (2D) cell migration assays do not provide information about vertical invasion processes, which are critical for melanoma progression. We provide information about three-dimensional (3D) melanoma cell migration, proliferation and invasion in a 3D melanoma skin equivalent (MSE) model. In particular, we pay careful attention to compare the structure of the tissues in the MSE with similarly-prepared 3D human skin equivalent (HSE) models. The HSE model is identically prepared to the MSE model except that melanoma cells are omitted...

The antagonism of mercury toxicity by selenium has been well documented. Mercury is a toxic metal, widespread in the environment. The main target organs (kidneys, lungs, or brain) of mercury vary depending on its chemical forms (inorganic or organic). Selenium is a semimetal essential to mammalian life as part of the amino acid selenocysteine, which is required to the synthesis of the selenoproteins. This chapter has the aim of disclosing the role of selenide or hydrogen selenide (Se(-2) or HSe(-)) as central metabolite of selenium and as an important antidote of the electrophilic mercury forms (particularly, Hg(2+) and MeHg)...

BACKGROUND: A relatively large body of literature examines the association between depression and alcohol consumption, with evidence suggesting a bidirectional causal relationship. However, the endogeneity arising from this reverse causation has not been addressed in the literature. METHODS: Using data on 5828 respondents from the Health Survey for England (HSE), this study revisits the relationship between alcohol and depression and addresses the endogenous nature of this relationship...

In Europe, employers of all private and public enterprises have a legal obligation to protect their employers by all the different types of workplace hazards to the safety and health of workers. The most important methods developed for the work-related stress risk assessment are based on the Cox's research commissioned by European Agency for Safety and Health at Work (EU-OSHA) and are the Management Standard HSE for work-related stress in United Kingdom, the START method in Germany, the Screening, Observation, Analysis, Expertise (SOBANE) in Belgium, and the National Institute for Prevention and Safety at Work (INAIL-ISPESL) model in Italy, the latter based on the British Management Standard...

In the last few decades, dye-sensitized solar cell (DSC) technology has been demonstrated to be a promising candidate for low cost energy production due to cost-effective materials and fabrication processes. Arguably, DSC stability is the biggest challenge for making this technology appealing for industrial exploitation. This work provides further insight into the stability of DSCs by considering specific dye-electrolyte systems characterized by Raman and impedance spectroscopy analysis. In particular, two ruthenium-based dyes, Z907 and Ru505, and two commercially available electrolytes, namely, the high stability electrolyte (HSE) and solvent-free Livion 12 (L-12), were tested...

Directional microwave-assisted liquefaction and stepwise extraction are introduced for producing platform chemicals: aromatics and monosaccharides. When sulfuric acid was used as a catalyst, a 45% monosaccharides yield and a 29% aromatics yield were obtained from bamboo with 0.3g catalyst per 18g methanol and 2g bamboo at 160°C with 10min. Approximately 78-86wt% of the six biomass materials were converted into liquid products. After the stepwise extraction and precipitation process, the yields of monosaccharide derivatives and three phenolic compound fractions were 39-45% and 28-32%, respectively...
