Epidemiologic evidence linking environmental exposure to polycyclic aromatic hydrocarbons (PAH) with breast cancer is limited. Measurement of DNA adducts formed by aromatic compounds, including PAH, has been carried in breast tissue samples and white blood cells from women with breast cancer and different kinds of controls. However, these studies provide inconsistent results and bias cannot be ruled out. During the 7-year follow-up period, 305 women were diagnosed with first primary breast cancer in the EPIC-Spain cohort, and were compared with a sample of 149 women without breast cancer at recruitment, using a case-cohort approach...

Liver fluke infection causes serious disease (fasciolosis) in cattle and sheep in many regions of the world, resulting in production losses and additional economic consequences due to condemnation of the liver at slaughter. Liver fluke depends on mud snails as an intermediate host and infect livestock when ingested through grazing. Therefore, environmental factors play important roles in infection risk and climate change is likely to modify this. Here, we demonstrate how slaughterhouse data can be integrated with other data, including animal movement and climate variables to identify environmental risk factors for liver fluke in cattle in Scotland...

During the past three decades, non-human primate (NHP) models have gained an increasing importance in HIV basic and translational research. In contrast to natural host models, infection of macaques with virulent simian or simian-human immunodeficiency viruses (SIV, SHIV) results in a disease that closely resembles HIV infection and AIDS. Although there is no perfect animal model, and each of the available models has its benefits and limitations, carefully designed NHP studies with selection of experimental variables have unraveled important questions of basic pathogenesis and have provided the tools to explore and screen intervention strategies...

A significant proportion of patients treated for schizophrenia respond poorly to medication. Few studies have systematically examined the impact of clinical characteristics of patients to antipsychotic response in our environment. The study aimed to identify clinical variables associated with response in patients with schizophrenia. A total of 172 participants diagnosed with schizophrenia, placed on antipsychotics, who presented for the first time to the hospital or have stopped medication in the preceding six months, whose responses were assessed after four to six weeks were studied...

Coral reef macroalgae are expected to thrive in the future under conditions that are deleterious to the health of reef-building corals. Here we examined how macroalgae would be affected by exposure to future CO2 emission scenarios (pCO2 and temperature), enriched nutrients and combinations of both. The species tested, Laurencia intricata (Rhodophyta), Turbinaria ornata and Chnoospora implexa (both Phaeophyceae), have active carbon-concentrating mechanisms but responded differently to the treatments. L. intricata showed high mortality under nutrient enriched RCP4...

The human ether-a-go-go-related gene (HERG) channel is a novel target for the treatment of drug-induced long QT syndrome, which causes lethal cardiotoxicity. This study is designed to explore the possible role of PML SUMOylation and its associated nuclear bodies (NBs) in the regulation of HERG protein expression. Both arsenic trioxide (ATO) and angiotensin II (Ang II) were able to significantly reduce HERG protein expression, while also increasing PML SUMOylation and accelerating the formation of PML-NBs. Pre-exposure of cardiomyocytes to a SUMOylation chemical inhibitor, ginkgolic acid, or the silencing of UBC9 suppressed PML SUMOylation, subsequently preventing the downregulation of HERG induced by ATO or Ang II...

The growing need to develop surfaces able to effectively resist biological fouling has resulted in the widespread investigation of nanomaterials with potential antifouling properties. However, the preparation of effective antifouling coatings is limited by the availability of reactive surface functional groups and our ability to carefully control and organise chemistries at a materials interface. Here, we present two methods of preparing hydrophilic low fouling surface coatings through reaction of silica nanoparticle suspensions and pre-deposited silica nanoparticle films with zwitterionic sulfobetaine...

Toxic effects induced by exposure to endocrine-disrupting chemicals during fetal and neonatal periods can be irreversible and exert effects throughout an animal's entire life. Our previous study showed that neonatal exposure to 17α-ethynyl estradiol (EE) induced irregular estrous cycle in adults. To uncover the reason for the delayed effect after neonatal exposure to EE, reproductive parameters including ovarian weight, ovarian steroidogenesis, and hormonal profiles were investigated in developing female rats...

BACKGROUND: Sleep-disordered breathing (SDB) is often co-morbid with conductive hearing loss in early childhood due to a shared aetiology of adenotonsillar hypertrophy. Hearing loss is independently associated with impairment of executive function and behavioural difficulties. We hypothesised that these impairments in children with SDB may be mediated through hearing loss. METHODS: Fifty-eight children including 37 snorers awaiting adenotonsillectomy and 21 healthy non-snoring controls, aged 3-5 years, were assessed with pure tone audiometry, Strengths and Difficulties (SDQ), Behaviour Rating of Executive Function (BRIEF-P), and Childhood Middle Ear Disease and Hearing questionnaires...

OBJECTIVE: Traumatic events, particularly those that are interpersonal in nature, are associated with increased risk for co-occurring sequelae, including sleep disturbances, posttraumatic stress disorder (PTSD), and alcohol use disorder (AUD). However, the associations between these phenotypes have not been explored among college students. METHODS: We examined relationships between type of potentially traumatic event (PTE) exposure (pre-college) and sleep disturbances, as well as mediating effects of lifetime PTSD and AUD symptoms on these relationships, in a large undergraduate sample (N = 1599, 64...

Lead in maternal blood can cross the placenta and result in elevated blood lead levels in newborns, potentially producing negative effects on neurocognitive function, particularly if combined with childhood lead exposure. Little research exists, however, into the burden of elevated blood lead levels in newborns, or the places and populations in which elevated lead levels are observed in newborns, particularly in rural settings. Using ~2300 dried bloods spots collected within 1-3 days of birth among Iowa newborns, linked with the area of mother's residence at the time of birth, we examine the spatial patterns of elevated (>5 μg/dL) blood lead levels and the ecological-level predictors of elevated blood lead levels...

BACKGROUND: Injury risk in youth rugby has received much attention, highlighting the importance of establishing evidence-based injury reduction strategies. AIM: To determine the efficacy of a movement control exercise programme in reducing injuries in youth rugby players and to investigate the effect of programme dose on injury measures. METHODS: In a cluster-randomised controlled trial, 40 independent schools (118 teams, 3188 players aged 14-18 years) were allocated to receive either the intervention or a reference programme, both of which were to be delivered by school coaches...

Chronic sun-induced dysplastic skin changes (actinic keratoses) are extremely common in fair-skinned people in Scotland. These changes are a major cause of morbidity and may develop into skin cancer. Actinic keratoses are often extensive and pose a therapeutic challenge as field-directed treatment is required for chronic disease management. One such treatment approach is hospital-based photodynamic therapy, which is a well-established treatment in Scotland for actinic keratoses, using a photosensitiser pro-drug and red LED light irradiation...

In the fresh produce industry, validation of sanitation efficacy is critical to prevent cross-contamination of produce. The current validation approaches are either based on time-consuming plate counting assays or indirect measurements of chemical properties of wash water. In the study, the focus was to identify biomarkers that can provide direct assessment of oxidative damage in bacteria upon exposure to sanitizers in the presence of fresh produce and correlation of these oxidative biomarkers with logarithmic inactivation of bacteria...

<span style="margin: 0px; font-family: 'New times rome',serif;">Prostate cancer is one of the leading causes of cancer death in US men. There is an unmet need to identify modifiable risk factors for prostate cancer survival. Experimental studies have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may improve prostate cancer survival through anti-thrombotic and anti-inflammation mechanisms. Results from previous observational studies have been equivocal, and few have assessed whether an etiologically relevant time window of exposure exists...

Pituitary adenylate cyclase activating polypeptide (PACAP) and its cognate receptor 1 (PAC1), have been implicated in the pathophysiology of the Sudden Infant Death Syndrome (SIDS). Two main risk factors for SIDS are prone sleeping and cigarette smoke exposure. Using piglet models of these risk factors, intermittent hypercapnic hypoxia (IHH-mimicking rebreathing in prone position) and nicotine (main reinforcing element of cigarettes), this study aimed to determine their effects on PACAP and PAC1 protein expression in the medulla...

Globally type 1 diabetes incidence is increasing. It is widely accepted that the pathophysiology of type 1 diabetes is influenced by environmental factors in people with specific human leukocyte antigen haplotypes. We propose that a complex interplay between dietary triggers, permissive gut factors and potentially other influencing factors underpins disease progression. We present evidence that A1 β-casein cows' milk protein is a primary causal trigger of type 1 diabetes in individuals with genetic risk factors...

BACKGROUND: SA237 is a humanized anti-interleukin-6 receptor (IL-6R) monoclonal antibody in which the constant and variable regions have been engineered for a longer plasma half-life. According to literature, blocking of IL-6 related functions could have an influence on pregnancy sustainment, development of the immune system, and brain growth. METHODS: SA237 effects on dams, embryo-fetal development, parturition and postnatal development were investigated in an enhanced pre- and postnatal development study, in which SA237 was subcutaneously administered to pregnant cynomolgus monkeys at dose levels of 2 or 50 mg/kg once weekly from gestation day 20 until parturition...

Diselenonicotinamide (DSNA), a synthetic organoselenium compound, was evaluated for its radioprotective effect in cellular models. A clonogenic assay in Chinese Hamster Ovary (CHO) cells and an apoptosis assay in murine splenic lymphocytes indicated that pre-treatment with DSNA at a concentration of 25 μM significantly protected them from radiation-induced cell death. Upon irradiation (1-12 Gy), dose-response studies were carried out under similar treatment conditions, and its dose modification factor (DMF) was estimated to be 1...

Seminal theories posit that fragmented trauma memories are critical to posttraumatic stress disorder (PTSD; van der Kolk & Fisler, 1995; Brewin, 2014) and that elaboration of the trauma narrative is necessary for recovery (e.g., Foa, Huppert, & Cahill, 2006). According to fragmentation theories, trauma narrative changes, particularly for those receiving trauma-focused treatment, should accompany symptom reduction. Trauma and control narratives in 77 men and women with chronic PTSD were examined pre- and post-treatment, comparing prolonged exposure (PE) and sertraline...
