There is a growing consensus in the scientific community that suggests a strong association between obstructive sleep apnea (OSA) and cardiovascular (CVD) conditions and events, including coronary artery disease, hypertension, arrhythmia, heart failure, and sudden cardiac death. We reviewed evidence on the relationship between OSA and arrhythmia. Our conclusion, based on our review of the literature, is that the evidence supports a strong link between OSA and cardiovascular mortality, which warrants treating OSA...

In this work, heterogeneous photocatalysis was used to treat pulp and paper mill effluent (PPME). Magnetically retrievable Fe2O3-TiO2 was fabricated by employing a solvent-free mechanochemical process under ambient conditions. Findings elucidated the successful incorporation of Fe2O3 into the TiO2 lattice. Fe2O3-TiO2 was found to be an irregular and slightly agglomerated surface morphology. In comparison to commercial P25, Fe2O3-TiO2 exhibited higher ferromagnetism and better catalyst properties with improvements in surface area (58...

Cu3(BTC)2 (BTC: 1,3,5-benzenetricarboxylic acid) showed to be an efficient and reusable heterogeneous solid catalyst for the formation of SiO bond through dehydrogenative coupling of dimethylphenylsilane (1) with phenol under mild reaction conditions. It is observed that Fe(BTC), MIL-101(Cr) and UiO-66(Zr) are not able to promote this cross coupling between 1 and phenol. Cu3(BTC)2 exhibits higher stability and activity compared to other MOFs studied here. Furthermore, Cu3(BTC)2 is reused for three consecutive cycles with a slight decay in its activity...

A considerable research effort is focused on developing effective delivery systems for hydrophobic nutraceuticals. β-carotene, a pro-vitamin A carotenoid, requires encapsulation to improve its water dispersibility and chemical stability in foods. In this study, β-carotene was encapsulated in oil-in-water nanoemulsions fabricated using high-pressure dual-channel microfluidization. Two types of natural emulsifier, quillaja saponins (Q-Naturale) and whey protein isolate (WPI), were capable of producing nanoemulsions (d32=0...

A quantitative human norovirus (NoV) exposure model describing transmission of NoV during pre-harvest, harvest and further processing of soft red fruits exemplified by raspberries is presented. The outcomes of the model demonstrate the presence of NoV in raspberry puree or individual quick frozen (IQF) raspberry fruits and were generated by Monte Carlo simulations by combining GoldSim® and @Risk® software. Input data were collected from scientific literature, observational studies and assumptions. NoV contamination of soft red fruits is assumed to take place at farms by application of contaminated water for pesticides dilution or by berries' pickers shedding NoV...

BACKGROUND: Metabotropic glutamate receptors (mGlu) play a role in a number of physiological processes and behaviors, as well as in certain pathological conditions and diseases. New drugs targetting mGlu receptors are being developed with treatment purposes. Recent data indicates that glutamate is involved in sleep, and pharmacological manipulation of distinct subtypes of mGlu receptors affect sleep. Here the consequences of selective pharmacological agonism of mGlu8 receptor upon sleep and wakefulness are explored for the first time...

BACKGROUND: Acute lung injury (ALI) is characterized by extensive neutrophil infiltration, and apoptosis delay considered part of the pathogenesis of the condition. Despite great advances in treatment strategies, few effective therapies are known for ALI. Diethylcarbamazine (DEC) is used against lymphatic filariasis, a number of studies have described its anti-inflammatory activities and pro-apoptotic effect. These properties have been associated with nuclear factor kappa-B inactivation...

The study goal was to examine the effectiveness of surfactants to decontaminate plastic and copper potable water plumbing components. Several common potable water pipe and gasket plastics were examined as well as Alconox(®) detergent, Dawn(®) soap, and MAGIT-DG 100 surfactants. Results showed that the MAGIT-DG 100 solutions permeated all plastics within 3days, effectively compromising tensile strength (-82%), physical dimension (+43% volume, +45% weight), and oxidative resistance (-15%). A variety of MAGIT-DG 100 solution compounds permeated plastic samples, not just the declared major ingredient...

The current trend towards the implementation of organic gunshot residue (OGSR) analysis into gunshot residue (GSR) investigation protocols typically involves the sequential analysis of inorganic and organic GSR. However, to allow for the consecutive analysis of inorganic and organic GSR, specimens will often be stored for different lengths of time which may result in compounds of interest degrading. In order to optimise storage conditions, it is important to consider compound degradation on collection devices during storage...

In-stent restenosis is one of the most serious modes of failure of cardiovascular stent implant. Although drug-eluting stents have been proven to reduce in-stent restenosis, the nonspecific inhibitory effects of anti-proliferative drugs, such as rapamycin, result in delayed re-endothelialization and fatal late stent thrombosis. Although many studies have focused on promoting rapid re-endothelialization, a feasible method of reducing excessive extracellular matrix (ECM) production and cell proliferation might provide a promising way to efficiently inhibit the restenosis in vivo...

Jie Gao, Peiyong Zhu, Ahmed Alsaedi, Fuad E Alsaadi, Tasawar Hayat
In this paper, finite-time synchronization (FTS) of memristor-based recurrent neural networks (MNNs) with time-varying delays is investigated by designing a new switching controller. First, by using the differential inclusions theory and set-valued maps, sufficient conditions to ensure FTS of MNNs are obtained under the two cases of 0<α<1 and α=0, and it is derived that α=0 is the critical value of 0<α<1. Next, it is discussed deeply on the relation between the parameter α and the synchronization time...

The photolysis of acetaminophen, a widely used pharmaceutical, in simulated natural organic matter solutions was investigated. The triplet states of natural organic matter ((3)NOM*) were found to play the dominant role in its photodegradation, while the contributions from hydroxyl radicals and singlet oxygen were negligible. Dissolved oxygen (DO) plays a dual role. From anaerobic to microaerobic (0.5 mg/L DO) conditions, the degradation rate of acetaminophen increased by 4-fold. That suggests the involvement of DO in reactions with the degradation intermediates...

Chagas disease reactivation has been a defining condition for acquired immune deficiency syndrome in Brazil for individuals coinfected with Trypanosoma cruzi and HIV since 2004. Although the first coinfection case was reported in the 1980s, its prevalence has not been firmly established. In order to know coinfection prevalence, a cross-sectional study of 200 HIV patients was performed between January and July 2013 in the city of Pelotas, in southern Rio Grande do Sul, an endemic area for Chagas disease. Ten subjects were found positive for T...

Plant-growth promoting rhizobacteria (PGPR) are studied as complements/alternatives to chemical fertilization in agriculture. Poor information however, exists on the potential of PGPR from undisturbed ecosystems. Here, we evaluated the plant growth-promoting (PGP) effect of rhizobacterial consortia from undisturbed Chilean arid-ecosystems (Consortium C1) and agro-ecosystems (Consortium C2) on plant biomass production. The PGP effects of C1 and C2 were assayed in wheat seedlings (Triticum aestivum L.) grown in pots under growth chamber conditions and in pots placed in an open greenhouse under natural conditions, using two different Chilean Andisols (Piedras Negras and Freire series) kept either at 30% or 60% of their maximum water holding capacity (MWHC)...

Adjustments of aerobic metabolic processes are critical components of organismal responses to environmental change that require tight co-ordination between the nuclear and mitochondrial genomes. Intraspecific differences in mitochondrial genotype can affect gene transcription in both genomes. Thus, variation in mitochondrial genotype may be associated with differences in the plasticity of gene expression when organisms are faced with changes in environmental conditions. Cold acclimation is known to result in metabolic responses involving increases in mitochondrial amount and capacity, suggesting that low temperatures may pose a particular challenge when co-ordinating the functions of the nuclear and mitochondrial genomes...

Multiple illnesses are common in all homeless populations. While most previous studies have focused on experiences of mental illness, there is a scarcity of studies about experiences of bodily illness among people who are homeless. This study aimed to explore illness narratives of people who are homeless, and how homelessness as a social context shapes the experience of multiple and/or advancing somatic conditions. The design was a qualitative single-case study, using interpretive description. Data were generated through interviews, with nine participants who were homeless rough sleepers in Stockholm, Sweden, recruited while receiving care in a support home for homeless people with complex care needs...

BACKGROUND: Vulnerability in the past has sometimes been measured and understood in terms of checklists or common understanding. It is argued here that vulnerability is a more complex issue than this. Although checklists of vulnerable groups are important, they do not capture the essence and dynamics of vulnerability. OBJECTIVE: The case of rural health vulnerability in South Africa is discussed to show that classifying people into vulnerable groups does not portray the complexity and intricacies of what it means to have vulnerability...
