RATIONALE: The association between obstructive sleep apnea (OSA) and cardiovascular disease (CVD) is complex, bi-directional, and may vary across groups. Understanding what cardiovascular risk factors vary in their relationship to OSA across population groups may improve the knowledge of the OSA-related CVD susceptibility. OBJECTIVE: To better understand the heterogeneity of associations, we assessed whether associations of OSA with cardiovascular risk factors vary by age, sex, and race/ethnicity...

Small diameter carbon nanotubes (CNTs) often require increased sophistication and control in synthesis processes, but exhibit improved physical properties and greater economic value over their larger diameter counterparts. Here, we study mechanisms controlling electrochemical synthesis of CNTs from the capture and conversion of ambient CO2 in molten salts, and leverage this understanding to achieve the smallest diameter CNTs ever reported in the literature from sustainable electrochemical synthesis routes, including some few-walled carbon nanotubes...

Ion mobility spectrometry (IMS) which acts as a rapid analysis technique is widely used in the field detection of illicit drugs and explosives. Due to limited separation abilities of the pint-sized IMS challenges and problems still exist regarding high false positive and false negative responses due to the interference of the matrix. In addition, the gas-phase ion chemistry and special phenomena in the IMS spectra, such one substance showing two peaks, were not identified unambiguously. In order to explain or resolve these questions, in this paper, an ion mobility spectrometry was coupled to a mass spectrometry (IMS-MS)...

Genetic epidemiological studies have provided evidence that several genes modify the link between air pollution and lung function. We assessed whether the adverse impacts of particulate matter with an aerodynamic diameter ≤10 μm (PM10 ) on lung function are modified by CYP1A1 gene polymorphisms in Korean adults. We used health check-up data from 1817 men, and the annual mean concentrations of ambient PM10 estimated from the ambient data. Three single nucleotide polymorphisms (SNPs) of CYP1A1 were selected for our study...

Long Non-Coding RNAs (lncRNAs) are functional RNAs longer than 200 nucleotides in length. Several lncRNAs are involved in cell proliferation and are deregulated in several human tumors. Few lncRNAs have been described to play a role in Acute Lymphoblastic Leukemia (ALL). In this study, we carried out a genome wide lncRNA expression profiling in ALL samples and peripheral blood samples obtained from healthy donors. We detected 43 lncRNAs that were aberrantly expressed in ALL. Interestingly, among them, linc-PINT showed a significant downregulation in T and B-ALL...

BACKGROUND: Uncertainties remain about the current risk of myocardial infarction (MI) after ischemic stroke or transient ischemic attack. METHODS AND RESULTS: We undertook a systematic review to estimate the long-term risk of MI, compared to recurrent stroke, with temporal trends in ischemic stroke/transient ischemic attack patients. Annual risks and 95% confidence intervals (95% CI) of MI and recurrent stroke were estimated using random-effect meta-analyses. We calculated incidence ratios of MI/recurrent stroke, for fatal and nonfatal events, using similar analyses...

BACKGROUND: Caesarean delivery carries a risk of major intra-operative blood loss and its performance is often delayed by non-availability of blood and blood products. Unnecessary cross-matching and reservation of blood lead to apparent scarcity in centres with limited supply. This study set out to identify the risk factors for blood transfusion in women who underwent caesarean delivery at a tertiary obstetric unit with a view to ensuring efficient blood utilization. METHODS: A prospective cohort analysis of 906 women who had caesarean deliveries at the Lagos State University Teaching Hospital, Nigeria between January and December, 2011...

BACKGROUND: The use of the potent oral P2Y12 inhibitors prasugrel and ticagrelor in patients with acute coronary syndromes (ACS) has a favorable net clinical effect compared with clopidogrel and is recommended as first-line therapy. However, the impact of these agents on ischemic and bleeding events in elderly ACS patients is not well defined. METHODS: We performed a systematic review of articles comparing potent P2Y12 inhibitors to clopidogrel in elderly and nonelderly patients (defined according to each study) with ACS in terms of efficacy (composite of cardiovascular death, myocardial infarction, or stroke) and safety (major bleeding) end points...

AIMS: The most recent European guidelines have proposed new definitions of pulmonary hypertension (PH) in left heart disease, to better approach the characteristics required to reflect the presence of pulmonary vascular disease. The purpose of this study was to assess whether different haemodynamic definitions of post-capillary PH imply a different reversibility of PH in response to acute vasodilator administration in heart failure patients with reduced ejection fraction and PH (HFrEF-PH)...

BACKGROUND: Plasma total homocysteine (tHcy) is related to plasma neopterin, an indicator of interferon-γ-mediated immune activation, and both biomarkers positively predict cardiovascular risk. We examined whether the association between tHcy and subsequent risk of acute myocardial infarction (AMI) was modified by systemic concentrations of neopterin and C-reactive protein among patients with coronary heart disease. METHODS AND RESULTS: By Cox modeling, we explored the association between tHcy and risk of AMI in 4164 patients with suspected stable angina pectoris...

The roles of specific fatty acids in breast cancer etiology are unclear, particularly among premenopausal women. We examined 34 individual fatty acids, measured in blood erythrocytes collected between 1996 and 1999, and breast cancer risk in a nested case-control study of primarily premenopausal women in the Nurses' Health Study II. Breast cancer cases diagnosed after blood collection and before June 2010 (n = 794) were matched to controls and conditional logistic regression was used to estimate OR's (95% CI's) for associations of fatty acids with breast cancer; unconditional logistic regression was used for stratified analyses...

Background  As technologies of percutaneous coronary intervention (PCI) for coronary chronic total occlusions (CTO) have improved, great uncertainty exists regarding patient selection and long-term benefit of CTO-PCI. Given that white blood cell (WBC) count has been associated with cardiovascular risk, we hypothesized that the latter might provide incremental prognostic value in patients undergoing CTO-PCI. Methods and Results  Our study population consisted of 1,262 consecutive patients (76.3% males, mean age of 67...

NMR spectroscopy is uniquely suited for atomic resolution studies of biomolecules such as proteins, nucleic acids and metabolites, since detailed information on structure and dynamics are encoded in positions and line shapes of peaks in NMR spectra. Unfortunately, accurate determination of these parameters is often complicated and time consuming, in part due to the need for different software at the various analysis steps and for validating the results. Here, we present an integrated, cross-platform and open-source software that is significantly more versatile than the typical line shape fitting application...

Research suggests that alcohol use and misuse are higher among lesbian, gay and bisexual than heterosexual populations, yet the social context of drinking in sexual minority communities has rarely been examined. To explore lesbian, gay, bisexual and transgender (LGBT) people's relationship with alcohol, we conducted seven focus groups (N = 33) with pre-existing groups of friends and work colleagues (18 to 52 years) in Scotland, UK. We identified and analysed patterns in our data using thematic analysis. Respondents perceived heavy drinking as central to the commercial gay scene...
