Hydrogen sulphide produced during metabolism of sulphate-reducing microorganisms (SRM) is toxic, corrosive and causes detrimental oil reservoir souring. During secondary oil recovery, injecting oil reservoirs with seawater that is rich in sulphate and that also cools high temperature formations provides favourable growth conditions for SRM. Nitrate addition can prevent metabolism of SRM by stimulating nitrate-reducing microorganisms (NRM). The investigations of thermophilic NRM are needed to develop mechanisms to control the metabolism of SRM in high temperature oil field ecosystems. We therefore established a model system consisting of enrichment cultures of cold surface marine sediments from the Baltic Sea (Aarhus Bay) that were incubated at 60°C. Enrichments contained 25 mM nitrate and 40 mM sulphate as potential electron acceptors, and a mixture of the organic substrates acetate, lactate, propionate, butyrate (5 mM each) and yeast extract (0.01%) as potential carbon sources and electron donors. Slurries were incubated at 60°C both with and without initial pasteurization at 80°C for 2 hours. In the enrichments containing both nitrate and sulphate, the concentration of nitrate decreased indicating metabolic activity of NRM. After a four-hour lag phase the rate of nitrate reduction increased and the concentration of nitrate dropped to zero after 10 hours of incubation. The concentration of nitrite increased as the reduction of nitrate progressed and reached 16.3 mM after 12 hours, before being consumed and falling to 4.4 mM after 19-day of incubation. No evidence for sulphate reduction was observed in these cultures during the 19-day incubation period. In contrast, the concentration of sulphate decreased up to 50% after one week incubation in controls containing only sulphate but no nitrate. Similar sulfate reduction rates were seen in the pasteurized controls suggesting the presence of heat resistant SRM, whereas nitrate reduction rates were lower in the

The "style of life is the unique way in which individuals try to realize their fictional final goal and meet or avoid the three main tasks of life: work, community, love" (Alfred Adler, founder of the Individual Psychology). Lifestyle refers to the way individuals live their lives and how they handle problems and interpersonal relations. The lifestyle behaviours associated to oral cancer with convincing evidence are tobacco use, betel quid chewing, alcohol drinking, low fruit and vegetable consumption (the detrimental lifestyle is high fat and/or sugar intake, resulting in low fruit and/or vegetable intake). Worldwide, 25% of oral cancers are attributable to tobacco usage (smoking and/or chewing), 7-19% to alcohol drinking, 10-15% to micronutrient deficiency, more than 50% to betel quid chewing in areas of high chewing prevalence. Carcinogenicity is dose-dependent and magnified by multiple exposures. Conversely, low and single exposures do not significantly increase oral cancer risk. These behaviours have common characteristics: (i) they are widespread: one billion men, 250 million women smoke cigarettes, 600-1200 million people chew betel quid, two billion consume alcohol, unbalanced diet is common amongst developed and developing countries; (ii) they were already used by animals and human forerunners millions of years ago because they were essential to overcome conditions such as cold, hunger, famine; their use was seasonal and limited by low availability, in contrast with the pattern of consumption of the modern era, characterized by routine, heavy usage, for recreational activities and with multiple exposures; (iii) their consumption in small doses is not recognized as detrimental by the human body and activates the dopaminergic reward system of the brain, thus giving instant pleasure, "liking" (overconsumption) and "wanting" (craving). For these reasons, effective Public Health measures aimed at preventing oral cancer and other lifestyle-related conditions

Sauropterygia, a successful clade of marine reptiles abundant in aquatic ecosystems of the Mesozoic, inhabited nearshore to pelagic habitats over >180 million years of evolutionary history [1]. Aquatic vertebrates experience strong buoyancy forces that allow movement in a three-dimensional environment, resulting in structural convergences such as flippers and fish-like bauplans [2, 3], as well as convergences in the sensory systems. We used computed tomographic scans of 19 sauropterygian species to determine how the transition to pelagic lifestyles influenced the evolution of the endosseous labyrinth, which houses the vestibular sensory organ of balance and orientation [4]. Semicircular canal geometries underwent distinct changes during the transition from nearshore Triassic sauropterygians to the later, pelagic plesiosaurs. Triassic sauropterygians have dorsoventrally compact, anteroposteriorly elongate labyrinths, resembling those of crocodylians. In contrast, plesiosaurs have compact, bulbous labyrinths, sharing some features with those of sea turtles. Differences in relative labyrinth size among sauropterygians correspond to locomotory differences: bottom-walking [5, 6] placodonts have proportionally larger labyrinths than actively swimming taxa (i.e., all other sauropterygians). Furthermore, independent evolutionary origins of short-necked, large-headed "pliosauromorph" body proportions among plesiosaurs coincide with reductions of labyrinth size, paralleling the evolutionary history of cetaceans [7]. Sauropterygian labyrinth evolution is therefore correlated closely with both locomotory style and body proportions, and these changes are consistent with isolated observations made previously in other marine tetrapods. Our study presents the first virtual reconstructions of plesiosaur endosseous labyrinths and the first large-scale, quantitative study detailing the effects of increasingly aquatic lifestyles on labyrinth morphology among marine reptiles.

Full Text Available Mono- and di-acylglycerol lipase has been applied to industrial usage in oil modification for its special substrate selectivity. Until now, the reported mono- and di-acylglycerol lipases from microorganism are limited, and there is no report on the mono- and di-acylglycerol lipase from bacteria. A predicted lipase (named MAJ1 from marine Janibacter sp. strain HTCC2649 was purified and biochemical characterized. MAJ1 was clustered in the family I.7 of esterase/lipase. The optimum activity of the purified MAJ1 occurred at pH 7.0 and 30 °C. The enzyme retained 50% of the optimum activity at 5 °C, indicating that MAJ1 is a cold-active lipase. The enzyme activity was stable in the presence of various metal ions, and inhibited in EDTA. MAJ1 was resistant to detergents. MAJ1 preferentially hydrolyzed mono- and di-acylglycerols, but did not show activity to triacylglycerols of camellia oil substrates. Further, MAJ1 is low homologous to that of the reported fungal diacylglycerol lipases, including Malassezia globosa lipase 1 (SMG1, Penicillium camembertii lipase U-150 (PCL, and Aspergillus oryzae lipase (AOL. Thus, we identified a novel cold-active bacterial lipase with a sn-1/3 preference towards mono- and di-acylglycerides for the first time. Moreover, it has the potential, in oil modification, for special substrate selectivity.

Bacteria belonging to the genus Pseudovibrio have been frequently found in association with a wide variety of marine eukaryotic invertebrate hosts, indicative of their versatile and symbiotic lifestyle. A recent comparison of the sponge-associated Pseudovibrio genomes has shed light on the mechanisms influencing a successful symbiotic association with sponges. In contrast, the genomic architecture of Pseudovibrio bacteria associated with other marine hosts has received less attention. Here, we performed genus-wide comparative analyses of 18 Pseudovibrio isolated from sponges, coral, tunicates, flatworm, and seawater. The analyses revealed a certain degree of commonality among the majority of sponge- and coral-associated bacteria. Isolates from other marine invertebrate host, tunicates, exhibited a genetic repertoire for cold adaptation and specific metabolic abilities including mucin degradation in the Antarctic tunicate-associated bacterium Pseudovibrio sp. Tun.PHSC04_5.I4. Reductive genome evolution was simultaneously detected in the flatworm-associated bacteria and the sponge-associated bacterium P. axinellae AD2, through the loss of major secretion systems (type III/VI) and virulence/symbioses factors such as proteins involved in adhesion and attachment to the host. Our study also unraveled the presence of a CRISPR-Cas system in P. stylochi UST20140214-052 a flatworm-associated bacterium possibly suggesting the role of CRISPR-based adaptive immune system against the invading virus particles. Detection of mobile elements and genomic islands (GIs) in all bacterial members highlighted the role of horizontal gene transfer for the acquisition of novel genetic features, likely enhancing the bacterial ecological fitness. These findings are insightful to understand the role of genome diversity in Pseudovibrio as an evolutionary strategy to increase their colonizing success across a wide range of marine eukaryotic hosts.

The passage from shore to marine life is a critical step in the development of juvenile penguins and is characterized by a fuel selection towards lipid oxidation concomitant to an enhancement of lipid-induced thermogenesis. However, mechanisms of such thermogenic improvement at fledging remain undefined. We used two different groups of pre-fledging king penguins (Aptenodytes patagonicus) to investigate the specific contribution of cold exposure during water immersion to lipid metabolism. Terrestrial penguins that had never been immersed in cold water were compared with experimentally cold-water immersed juveniles. Experimentally immersed penguins underwent ten successive immersions at approximately 9-10 °C for 5 h over 3 weeks. We evaluated adaptive thermogenesis by measuring body temperature, metabolic rate and shivering activity in fully immersed penguins exposed to water temperatures ranging from 12 to 29 °C. Both never-immersed and experimentally immersed penguins were able to maintain their homeothermy in cold water, exhibiting similar thermogenic activity. In vivo, perfusion of lipid emulsion at thermoneutrality induced a twofold larger calorigenic response in experimentally immersed than in never-immersed birds. In vitro, the respiratory rates and the oxidative phosphorylation efficiency of isolated muscle mitochondria were not improved with cold-water immersions. The present study shows that acclimation to cold water only partially reproduced the fuel selection towards lipid oxidation that characterizes penguin acclimatization to marine life.

Cold-climate slope deposits and landscape modifications of the Mid-Atlantic Coastal Plain, Eastern USA

2011-01-01

The effects of Pleistocene cold-climate geomorphology are distributed across the weathered and eroded Mid-Atlantic Coastal Plain uplands from the Wisconsinan terminal moraine south to Tidewater Virginia. Cold-climate deposits and landscape modifications are superimposed on antecedent landscapes of old, weathered Neogene upland gravels and Pleistocene marine terraces that had been built during warm periods and sea-level highstands. In New Jersey, sequences of surficial deposits define a long history of repeating climate change events. To the south across the Delmarva Peninsula and southern Maryland, most antecedent topography has been obscured by Late Pleistocene surficial deposits. These are spatially variable and are collectively described as a cold-climate alloformation. The cold-climate alloformation includes time-transgressive details of climate deterioration from at least marine isotope stage (MIS) 4 through the end of MIS 2. Some deposits and landforms within the alloformation may be as young as the Younger Dryas. Southwards along the trend of the Potomac River, these deposits and their climatic affinities become diffused. In Virginia, a continuum of erosion and surficial deposits appears to be the product of ‘normal’ temperate, climate-forced processes. The cold-climate alloformation and more temperate deposits in Virginia are being partly covered by Holocene alluvium and bay mud.

Seasonal variation of marine organic aerosols in the North Pacific Ocean

Atmospheric aerosols were collected in the marine boundary layer during five marine cruises in the northern Pacific Ocean from October 1996 to July 1997. Organic molecular compositions of the marine aerosols were measured using gas chromatography/mass spectrometry (GC/MS). Higher concentrations of levoglucosan and its isomers, the biomass-burning tracers, were observed in the coastal regions than those in the central north Pacific. Seasonal trends of biomass burning tracers were found to be higher in fall-winter-spring than in summer, suggesting an enhanced influence of continental aerosols to the marine atmosphere during cold seasons when the westerlies prevail. However, the atmospheric levels of secondary organic aerosol (SOA) tracers from the photooxidation of isoprene and monoterpenes were higher in warm seasons than cold seasons, which are in accordance with the enhanced emissions of biogenic volatile organic compounds (BVOCs) in summer. Stable C isotope ratios of total carbon (δ13CTC) in the marine aerosols ranged from -28.5‰ to -23.6‰ (mean -26.4‰), suggesting an important input of terrestrial/continental aerosol particles. Stable N isotope ratios (2.6‰ to 12.9‰, mean 7.1‰) were found to be higher in the coastal regions than those in the open oceans, suggesting an enhanced emission of marine aerosols in the open oceans. The fluorescence properties of the water-soluble organic carbon (WSOC) in the marine aerosols conform the importance of marine emitted organics in the open ocean, especially during the high biological activity periods.

ι-Carrageenases play a role in marine ι-carrageenan degradation, and their enzymatic hydrolysates are thought to be excellent antioxidants. In this study, we identified a new ι-carrageenase, encoded by cgiF, in psychrophilic bacterium Flavobacterium sp. YS-80-122. The deduced ι-carrageenase, CgiF, belongs to glycoside hydrolase family 82 and shows less than 40% amino acid identity with characterized ι-carrageenases. The activity of recombinant CgiF peaked at 30°C (1,207.8U/mg). Notably, CgiF is a cold-adapted ι-carrageenase, which showed 36.5% and 57% of the maximum activity at 10°C and 15°C, respectively. In addition, it is a thermo-tolerant enzyme that recovered 58.2% of its initial activity after heat shock. Furthermore, although the activity of CgiF was enhanced by NaCl, the enzyme is active in absence of NaCl. This study also shows that CgiF is an endo-type ι-carrageenase that hydrolyzes β-1,4-linkages of ι-carrageenan, yielding neo-ι-carratetraose as the main product. Its cold-adaptation, thermo-tolerance, NaCl independence and high neo-ι-carratetraose yield make CgiF an excellent candidate for industrial applications in production of ι-carrageen oligosaccharides from seaweed polysaccharides.

Physiological basis for high CO2 tolerance in marine ectothermic animals: pre-adaptation through lifestyle and ontogeny?

Directory of Open Access Journals (Sweden)

M. Bleich

2009-10-01

Full Text Available Future ocean acidification has the potential to adversely affect many marine organisms. A growing body of evidence suggests that many species could suffer from reduced fertilization success, decreases in larval- and adult growth rates, reduced calcification rates, and even mortality when being exposed to near-future levels (year 2100 scenarios of ocean acidification. Little research focus is currently placed on those organisms/taxa that might be less vulnerable to the anticipated changes in ocean chemistry; this is unfortunate, as the comparison of more vulnerable to more tolerant physiotypes could provide us with those physiological traits that are crucial for ecological success in a future ocean. Here, we attempt to summarize some ontogenetic and lifestyle traits that lead to an increased tolerance towards high environmental pCO2. In general, marine ectothermic metazoans with an extensive extracellular fluid volume may be less vulnerable to future acidification as their cells are already exposed to much higher pCO2 values (0.1 to 0.4 kPa, ca. 1000 to 3900 μatm than those of unicellular organisms and gametes, for which the ocean (0.04 kPa, ca. 400 μatm is the extracellular space. A doubling in environmental pCO2 therefore only represents a 10% change in extracellular pCO2 in some marine teleosts. High extracellular pCO2 values are to some degree related to high metabolic rates, as diffusion gradients need to be high in order to excrete an amount of CO2 that is directly proportional to the amount of O2 consumed. In active metazoans, such as teleost fish, cephalopods and many brachyuran crustaceans, exercise induced increases in metabolic rate require an efficient ion-regulatory machinery for CO2 excretion and acid-base regulation, especially when anaerobic metabolism is involved and metabolic protons leak into the extracellular space. These ion-transport systems, which are located in highly developed gill epithelia, form the basis for

Full Text Available Public health recommendations for lifestyle modification, including diet and physical activity, have been widely disseminated for the prevention and treatment of disease. These guidelines are intended for the overall population without significant consideration for the individual with respect to one’s genes and environment. Personalized lifestyle medicine is a newly developed term that refers to an approach to medicine in which an individual’s health metrics from point-of-care diagnostics are used to develop lifestyle medicine-oriented therapeutic strategies for improving individual health outcomes in managing chronic disease. Examples of the application of personalized lifestyle medicine to patient care include the identification of genetic variants through laboratory tests and/or functional biomarkers for the purpose of designing patient-specific prescriptions for diet, exercise, stress, and environment. Personalized lifestyle medicine can provide solutions to chronic health problems by harnessing innovative and evolving technologies based on recent discoveries in genomics, epigenetics, systems biology, life and behavioral sciences, and diagnostics and clinical medicine. A comprehensive, personalized approach to medicine is required to promote the safety of therapeutics and reduce the cost of chronic disease. Personalized lifestyle medicine may provide a novel means of addressing a patient’s health by empowering them with information they need to regain control of their health.

The concept of 'lifestyle' includes different factors such as nutrition, behavior, stress, physical activity, working habits, smoking and alcohol consumption. Increasing evidence shows that environmental and lifestyle factors may influence epigenetic mechanisms, such as DNA methylation, histone acetylation and miRNA expression. It has been identified that several lifestyle factors such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress and working on night shifts might modify epigenetic patterns. Most of the studies conducted so far have been centered on DNA methylation, whereas only a few investigations have studied lifestyle factors in relation to histone modifications and miRNAs. This article reviews current evidence indicating that lifestyle factors might affect human health via epigenetic mechanisms.

Historical overexploitation of marine mammals, combined with present-day pressures, has resulted in severely depleted populations, with many species listed as threatened or endangered. Understanding breeding patterns of threatened marine mammals is crucial to assessing population viability, potential recovery and conservation actions. However, determining reproductive parameters of wild fully-marine mammals (cetaceans and sirenians) is challenging due to their wide distributions, high mobility, inaccessible habitats, cryptic lifestyles and in many cases, large body size and intractability. Consequently, reproductive biologists employ an innovative suite of methods to collect useful information from these species. This chapter reviews historic, recent and state-of-the-art methods to examine diverse aspects of reproduction in fully-aquatic mammals.

Microbial community changes along the active seepage site of one cold seep in the Red Sea.

The active seepage of the marine cold seeps could be a critical process for the exchange of energy between the submerged geosphere and the sea floor environment through organic-rich fluids, potentially even affecting surrounding microbial habitats. However, few studies have investigated the associated microbial community changes. In the present study, 16S rRNA genes were pyrosequenced to decipher changes in the microbial communities from the Thuwal seepage point in the Red Sea to nearby marine sediments in the brine pool, normal marine sediments and water, and benthic microbial mats. An unexpected number of reads from unclassified groups were detected in these habitats; however, the ecological functions of these groups remain unresolved. Furthermore, ammonia-oxidizing archaeal community structures were investigated using the ammonia monooxygenase subunit A (amoA) gene. Analysis of amoA showed that planktonic marine habitats, including seeps and marine water, hosted archaeal ammonia oxidizers that differed from those in microbial mats and marine sediments, suggesting modifications of the ammonia oxidizing archaeal (AOA) communities along the environmental gradient from active seepage sites to peripheral areas. Changes in the microbial community structure of AOA in different habitats (water vs. sediment) potentially correlated with changes in salinity and oxygen concentrations. Overall, the present results revealed for the first time unanticipated novel microbial groups and changes in the ammonia-oxidizing archaea in response to environmental gradients near the active seepages of a cold seep.

Are glendonites reliable indicators of cold conditions? Evidence from the Lower Cretaceous of Spitsbergen

Science.gov (United States)

Vickers, Madeleine; Price, Gregory; Watkinson, Matthew; Jerrett, Rhodri

2017-04-01

Glendonites are pseudomorphs after the mineral ikaite, and have been found in marine sediments throughout geological time. Ikaite is a metastable, hydrated form of calcium carbonate, which is only stable under specific conditions: between -2 and +5 °C, and with high alkalinity and phosphate concentrations. Glendonites are often associated with cold climates due to the strong temperature control on ikaite growth, and the coincidence in the geological record with episodes of global cooling. Glendonites are found in the Lower Cretaceous succession in Spitsbergen. During the Early Cretaceous, Spitsbergen was at a palaeolatitude of 60°N, and was part of a shallow epicontinental sea that formed during the Mesozoic as Atlantic rifting propagated northwards. Though the Early Cretaceous was generally characterised by greenhouse climate conditions, episodic cold snaps occurred during the Valanginian (the "Weissert Event") and during Aptian-Albian. Using high resolution carbon-isotope stratigraphy, we show that the first occurrences of glendonites are in the upper Lower Hauterivian and in the very upper Upper Hauterivian, stratigraphically higher than the Valanginian cooling event. Glendonites are also found in horizons in the Upper Aptian, coincident with the Aptian-Albian cold snap. Petrological analysis of the glendonite structure reveals differences between the Hauterivian and Aptian glendonites, with evidence for multiple diagenetic phases of growth in the Hauterivian glendonites, suggesting oscillating chemical conditions. This evidence suggests that local environmental conditions may have a stronger control on glendonite formation and preservation than global climate. We present a new model for ikaite growth and slow transformation to glendonite in marine sediments, which points to a more complex suite of diagenetic transformations than previously modelled. Furthermore, we critically assess whether such pseudomorphs after marine sedimentary ikaite may be indicators

A constant flux of diverse thermophilic bacteria into the cold arctic seabed

Microorganisms have been repeatedly discovered in environments that do not support their metabolic activity. Identifying and quantifying these misplaced organisms can reveal dispersal mechanisms that shape natural microbial diversity. Using endospore germination experiments, we estimated a stable...... supply of thermophilic bacteria into permanently cold Arctic marine sediment at a rate exceeding 108 spores per square meter per year. These metabolically and phylogenetically diverse Firmicutes show no detectable activity at cold in situ temperatures but rapidly mineralize organic matter by hydrolysis......, fermentation, and sulfate reduction upon induction at 50°C. The closest relatives to these bacteria come from warm subsurface petroleum reservoir and ocean crust ecosystems, suggesting that seabed fluid flow from these environments is delivering thermophiles to the cold ocean. These transport pathways may...

Alginates are abundant polysaccharides in brown algae that constitute an important energy source for marine heterotrophic bacteria. Despite the key role of alginate assimilation processes in the marine carbon cycle, little information is available on the bacterial populations involved in these processes. The goal of this work was to gain insight into the structure and functional traits of the alginolytic communities from sediments of cold coastal environments. Sediment metagenomes from high-latitude regions of both Hemispheres were interrogated for alginate lyase gene homolog sequences and their genomic context. Sediments contained highly abundant and diverse bacterial assemblages with alginolytic potential, including members of Bacteroidetes and Proteobacteria, as well as several poorly characterized taxa. Temperature and salinity were correlated to the variation in community structure. The microbial communities in Arctic and Antarctic sediments exhibited the most similar alginolytic profiles, whereas brackish sediments had a higher proportion of novel members. Examination of the gene context of the alginate lyase homologs revealed distinct patterns according to the phylogenetic origin of the scaffolds, with evidence of evolutionary relationships among lineages. This information is relevant for understanding carbon fluxes in cold coastal environments and provides valuable information for the development of biotechnological applications from brown algae biomass.

Sea surface temperature contributes to marine crocodylomorph evolution.

Martin, Jeremy E; Amiot, Romain; Lécuyer, Christophe; Benton, Michael J

2014-08-18

During the Mesozoic and Cenozoic, four distinct crocodylomorph lineages colonized the marine environment. They were conspicuously absent from high latitudes, which in the Mesozoic were occupied by warm-blooded ichthyosaurs and plesiosaurs. Despite a relatively well-constrained stratigraphic distribution, the varying diversities of marine crocodylomorphs are poorly understood, because their extinctions neither coincided with any major biological crises nor with the advent of potential competitors. Here we test the potential link between their evolutionary history in terms of taxic diversity and two abiotic factors, sea level variations and sea surface temperatures (SST). Excluding Metriorhynchoidea, which may have had a peculiar ecology, significant correlations obtained between generic diversity and estimated Tethyan SST suggest that water temperature was a driver of marine crocodylomorph diversity. Being most probably ectothermic reptiles, these lineages colonized the marine realm and diversified during warm periods, then declined or became extinct during cold intervals.

Recent Advances in Marine Enzymes for Biotechnological Processes.

Science.gov (United States)

Lima, R N; Porto, A L M

In the last decade, new trends in the food and pharmaceutical industries have increased concern for the quality and safety of products. The use of biocatalytic processes using marine enzymes has become an important and useful natural product for biotechnological applications. Bioprocesses using biocatalysts like marine enzymes (fungi, bacteria, plants, animals, algae, etc.) offer hyperthermostability, salt tolerance, barophilicity, cold adaptability, chemoselectivity, regioselectivity, and stereoselectivity. Currently, enzymatic methods are used to produce a large variety of products that humans consume, and the specific nature of the enzymes including processing under mild pH and temperature conditions result in fewer unwanted side-effects and by-products. This offers high selectivity in industrial processes. The marine habitat has been become increasingly studied because it represents a huge source potential biocatalysts. Enzymes include oxidoreductases, hydrolases, transferases, isomerases, ligases, and lyases that can be used in food and pharmaceutical applications. Finally, recent advances in biotechnological processes using enzymes of marine organisms (bacterial, fungi, algal, and sponges) are described and also our work on marine organisms from South America, especially marine-derived fungi and bacteria involved in biotransformations and biodegradation of organic compounds. © 2016 Elsevier Inc.

In many countries around the world, negative changes in lifestyles are observed. The aim of this study was to analyze the influence of selected lifestyle indicators on work ability among professionally active individuals. The study was performed in the randomly selected group of full-time employees (94 men and 93 women) living in the city of Lódź. Work ability was measured with the work ability index and lifestyle characteristic was assessed with the healthy lifestyle index. We analyzed four lifestyle indicators: non-smoking, healthy weight, fiber intake per day, and regular physical activity. Logistic regression was used to estimate odds ratios and 95% confidence intervals to control the effects of lifestyle and work ability. The analysis of lifestyle index indicated that 27.7, 30.9, 27.7 and 11.7% of men and 15.1, 21.5, 35.5 and 26.9% of women scored 0, 1, 2, 3 points, respectively. Only 2.1% of men and 1.1% of women met the criteria for the healthy lifestyle (score 4). Work ability was excellent, good and moderate in 38.3, 46.8 and 14.9% of men, and in 39.8, 14.9 and 19.3% of women, respectively. Poor work ability was found in 9.7% women. Work ability was strongly associated with lifestyle in both men and women. Among men with index score = 0, the risk of moderate work ability was nearly seven times higher than in men whose lifestyle index score exceeded 1 or more points (OR = 6.67; 95% CI: 1.94-22.90). Among women with lifestyle index score = 0, the risk of moderate or lower work ability was also highly elevated as compared to those with lifestyle index = 1 or higher (OR = 14.44; 95% CI: 3.53-59.04). Prophylactic schedules associated with the improvement of lifestyles should be addressed to all adults. Future programs aimed at increasing work ability should consider work- and lifestyle-related factors.

Recently it was suggested that the phylogenetic clustering of Mesozoic marine reptile lineages, such as thalattosaurs, the very successful fish-shaped ichthyosaurs and sauropterygians (including plesiosaurs), among others, in a so-called 'superclade' is an artefact linked to convergent evolution of morphological characters associated with a shared marine lifestyle. Accordingly, partial 'un-scoring' of the problematic phylogenetic characters was proposed. Here we report a new, exceptionally preserved and mostly articulated juvenile skeleton of the diapsid reptile, Eusaurosphargis dalsassoi, a species previously recovered within the marine reptile 'superclade', for which we now provide a revised diagnosis. Using micro-computed tomography, we show that besides having a deep skull with a short and broad rostrum, the most outstanding feature of the new specimen is extensive, complex body armour, mostly preserved in situ, along its vertebrae, ribs, and forelimbs, as well as a row of flat, keeled ventrolateral osteoderms associated with the gastralia. As a whole, the anatomical features support an essentially terrestrial lifestyle of the animal. A review of the proposed partial character 'un-scoring' using three published data matrices indicate that this approach is flawed and should be avoided, and that within the marine reptile 'superclade' E. dalsassoi potentially is the sister taxon of Sauropterygia.

2005-12-01

Full Text Available Abstract Background Pain is elicited by cold, and a major feature of many neuropathic pain states is that normally innocuous cool stimuli begin to produce pain (cold allodynia. To expand our understanding of cold induced pain states we have studied cold pain behaviors over a range of temperatures in several animal models of chronic pain. Results We demonstrate that a Peltier-cooled cold plate with ± 1°C sensitivity enables quantitative measurement of a detection withdrawal response to cold stimuli in unrestrained rats. In naïve rats the threshold for eliciting cold pain behavior is 5°C. The withdrawal threshold for cold allodynia is 15°C in both the spared nerve injury and spinal nerve ligation models of neuropathic pain. Cold hyperalgesia is present in the spared nerve injury model animals, manifesting as a reduced latency of withdrawal response threshold at temperatures that elicit cold pain in naïve rats. We also show that following the peripheral inflammation produced by intraplantar injection of complete Freund's adjuvant, a hypersensitivity to cold occurs. Conclusion The peltier-cooled provides an effective means of assaying cold sensitivity in unrestrained rats. Behavioral testing of cold allodynia, hyperalgesia and pain will greatly facilitate the study of the neurobiological mechanisms involved in cold/cool sensations and enable measurement of the efficacy of pharmacological treatments to reduce these symptoms.

European society is experiencing unprecedented changes triggered by expansion of the European Union, the fall of Communism, economic growth and the onset of globalisation. Europe's regional seas, the Baltic, Black Sea, Mediterranean and North-East Atlantic (including the North Sea), provide key goods and services to the human population but have suffered from severe degradation in past decades. Their integrity as coupled social and ecological systems depends on how humanity will anticipate potential problems and deal with its ecological footprint in the future. We report the outcome of an EU-funded 15-country, 28 institution project entitled European Lifestyles and Marine Ecosystems (ELME). Our studies were designed to inform new EU policy and legislation that incorporates Ecosystem-Based Management. ELME has modelled the key relationships between economic and social drivers (D), environmental pressures (P) and changes in the state of the environment (S) in Europe's regional seas. We examined four key issues in each sea: habitat change, eutrophication, chemical pollution and fisheries. We developed conceptual models for each regional sea and employed a novel stochastic modelling technique to examine the interrelationship between key components of the conceptual models. We used the models to examine 2-3 decade projections of current trends in D, P and S and how a number of alternative development scenarios might modify these trends. These simulations demonstrate the vulnerability of Europe's seas to human pressure. As affluence increases in countries acceding to the EU, so does the demand for marine goods and services. There are `winners' and `losers' amongst marine species; the winners are often species that are opportunistic invaders or those with low economic value. In the case of eutrophication, semi-enclosed seas such as the Baltic or Black Sea are already affected by the `legacy of the past'; nutrients that have accumulated in soils, ground waters and

The clean-up of oil spills in the Arctic environment is often limited by severe and cold environmental conditions. Mechanical methods are usually considered to be most favorable for oil spill combatting. However, remote spill sites, long distances, severe environmental conditions and sensitive ecosystems mean that more advanced combatting techniques are also needed to back up conventional recovery and clean-up measures. This paper describes the results of macro-scale tests conducted by VTT Manufacturing Technology to study the effectiveness of biosorbent technology against marine oil spills. The use of biosorbents was studied as a joint research project involving VTT (Finland) and the Murmansk Marine Biological Institute (Russia). Selected biosorbent products of Marine Systems, U.S.A., and the Bios Group, Russia, were used in macro-scale tests conducted in a basin measuring 15.0 x 3.0 m in length and width, respectively. This paper outlines the macro-scale test project, including microbiological and chemical studies, supported by toxicity tests and various analyses to understand better the fate of oil, especially the degree of biodegradation during the test

Background Lifestyle medicine is the science and application of healthy lifestyles as interventions for the prevention and treatment of disease, and has gained significant momentum as a specialty in recent years. College is a critical time for maintenance and acquisition of healthy habits. Longer-term, more intensive web-based and in-person lifestyle medicine interventions can have a positive effect. Students who are exposed to components of lifestyle medicine in their education have improvements in their health behaviors. A semester-long undergraduate course focused on lifestyle medicine can be a useful intervention to help adopt and sustain healthy habits. Objective To describe a novel, evidence based curriculum for a course teaching the concepts of Lifestyle Medicine based on a web-based course offered at the Harvard Extension School. Methods The course was delivered in a web-based format. The Lifestyle Medicine course used evidence based principles to guide students toward a “coach approach” to behavior change, increasing their self-efficacy regarding various lifestyle-related preventive behaviors. Students are made to understand the cultural trends and national guidelines that have shaped lifestyle medicine recommendations relating to behaviors. They are encouraged to engage in behavior change. Course topics include physical activity, nutrition, addiction, sleep, stress, and lifestyle coaching and counseling. The course addressed all of the American College of Preventive Medicine/American College of Lifestyle Medicine competencies save for the competency of office systems and technologies to support lifestyle medicine counseling. Results The course was well-received, earning a ranking of 4.9/5 at the school. Conclusions A novel, semester-long course on Lifestyle Medicine at the Harvard Extension School is described. Student evaluations suggest the course was well-received. Further research is needed to evaluate whether such a course empowers students to

Damayanthi Durairajanayagam

2018-03-01

Full Text Available Objective: To examine the potential effects of lifestyle factors on male reproductive health. Evidence of a global decline in human sperm quality over recent decades has been accumulating. Environmental, occupational, and modifiable lifestyle factors may contribute to this decline. This review focuses on key lifestyle factors that are associated with male infertility such as smoking cigarettes, alcohol intake, use of illicit drugs, obesity, psychological stress, advanced paternal age, dietary practices, and coffee consumption. Other factors such as testicular heat stress, intense cycling training, lack of sleep and exposure to electromagnetic radiation from mobile phone use are briefly discussed. Materials and method: A comprehensive literature search was performed to identify and synthesise all relevant information, mainly from within the last decade, on the major lifestyle factors associated with male infertility and semen quality. Database searches were limited to reports published in English only. A manual search of bibliographies of the reports retrieved was conducted to identify additional relevant articles. Results: In all, 1012 articles were identified from the database search and after reviewing the titles and abstract of the reports, 104 articles met the inclusion criteria. Of these, 30 reports were excluded as the full-text could not be retrieved and the abstract did not have relevant data. The remaining 74 reports were reviewed for data on association between a particular lifestyle factor and male infertility and were included in the present review. Conclusion: The major lifestyle factors discussed in the present review are amongst the multiple potential risk factors that could impair male fertility. However, their negative impact may well be mostly overcome by behaviour modification and better lifestyle choices. Greater awareness and recognition of the possible impact of these lifestyle factors are important amongst couples seeking

Latent lifestyle preferences and household location decisions

Walker, Joan L.; Li, Jieping

2007-04-01

Lifestyle, indicating preferences towards a particular way of living, is a key driver of the decision of where to live. We employ latent class choice models to represent this behavior, where the latent classes are the lifestyles and the choice model is the choice of residential location. Thus, we simultaneously estimate lifestyle groups and how lifestyle impacts location decisions. Empirical results indicate three latent lifestyle segments: suburban dwellers, urban dwellers, and transit-riders. The suggested lifestyle segments have intriguing policy implications. Lifecycle characteristics are used to predict lifestyle preferences, although there remain significant aspects that cannot be explained by observable variables.

The Lifestyle Change Experiences of Cancer Survivors.

Tsay, Shiow-Luan; Ko, Wang-Sheng; Lin, Kuan-Pin

2017-10-01

Leading a healthy lifestyle not only alleviates the physical problems but also improves the quality of life of cancer survivors. Healthcare professionals should understand the benefits of altering lifestyle behaviors to provide effective intervention programs to assist cancer survivors to improve their health. The aim of this study was to understand the experiences of cancer survivors in changing their lifestyle after a cancer diagnosis. A qualitative descriptive study was conducted on 13 cancer survivors who were sampled purposively from a regional teaching hospital in central Taiwan. Data were collected using in-depth interviews that were guided by semistructured, open-ended questions and analyzed using content analysis. The analysis of interview data revealed four main themes: motivation of lifestyle change, exploring ways toward a healthy lifestyle, making adjustments in lifestyle, and feeling the benefits of lifestyle changes. In striving for survival, an unwillingness to bear the suffering from treatment and their acceptance of responsibility and gratitude to family members prompted most of the participants to change their lifestyle proactively. They had received inadequate lifestyle guidance and sought health lifestyle information on their own. After a period of research and self-contemplation, most of the participants adopted a consistently healthy lifestyle, changed their dietary consumption habits, abstained from tobacco and alcohol, and managed emotional problems that were caused by the disease. Participants who changed to a healthy lifestyle realized benefits in the physical, emotional, and life domains. It is hoped that these findings help healthcare professionals to better appreciate that a cancer diagnosis is a critical opportunity to link the disease to lifestyle choices in the minds of cancer survivors. Healthcare professionals should ask cancer survivors about their lifestyle and then provide appropriate advice and education on healthy lifestyles

How cold is cold dark matter?

International Nuclear Information System (INIS)

Armendariz-Picon, Cristian; Neelakanta, Jayanth T.

2014-01-01

If cold dark matter consists of particles, these must be non-interacting and non-relativistic by definition. In most cold dark matter models however, dark matter particles inherit a non-vanishing velocity dispersion from interactions in the early universe, a velocity that redshifts with cosmic expansion but certainly remains non-zero. In this article, we place model-independent constraints on the dark matter temperature to mass ratio, whose square root determines the dark matter velocity dispersion. We only assume that dark matter particles decoupled kinetically while non-relativistic, when galactic scales had not entered the horizon yet, and that their momentum distribution has been Maxwellian since that time. Under these assumptions, using cosmic microwave background and matter power spectrum observations, we place upper limits on the temperature to mass ratio of cold dark matter today (away from collapsed structures). These limits imply that the present cold dark matter velocity dispersion has to be smaller than 54 m/s. Cold dark matter has to be quite cold, indeed

Marine Enzymes and Microorganisms for Bioethanol Production.

Science.gov (United States)

Swain, M R; Natarajan, V; Krishnan, C

Bioethanol is a potential alternative fuel to fossil fuels. Bioethanol as a fuel has several economic and environmental benefits. Though bioethanol is produced using starch and sugarcane juice, these materials are in conflict with food availability. To avoid food-fuel conflict, the second-generation bioethanol production by utilizing nonfood lignocellulosic materials has been extensively investigated. However, due to the complexity of lignocellulose architecture, the process is complicated and not economically competitive. The cultivation of lignocellulosic energy crops indirectly affects the food supplies by extensive land use. Marine algae have attracted attention to replace the lignocellulosic feedstock for bioethanol production, since the algae grow fast, do not use land, avoid food-fuel conflict and have several varieties to suit the cultivation environment. The composition of algae is not as complex as lignocellulose due to the absence of lignin, which renders easy hydrolysis of polysaccharides to fermentable sugars. Marine organisms also produce cold-active enzymes for hydrolysis of starch, cellulose, and algal polysaccharides, which can be employed in bioethanol process. Marine microoorganisms are also capable of fermenting sugars under high salt environment. Therefore, marine biocatalysts are promising for development of efficient processes for bioethanol production. © 2017 Elsevier Inc. All rights reserved.

Genomes of planktonic Acidimicrobiales: widening horizons for marine Actinobacteria by metagenomics.

Mizuno, Carolina Megumi; Rodriguez-Valera, Francisco; Ghai, Rohit

2015-02-10

The genomes of four novel marine Actinobacteria have been assembled from large metagenomic data sets derived from the Mediterranean deep chlorophyll maximum (DCM). These are the first marine representatives belonging to the order Acidimicrobiales and only the second group of planktonic marine Actinobacteria to be described. Their streamlined genomes and photoheterotrophic lifestyle suggest that they are planktonic, free-living microbes. A novel rhodopsin clade, acidirhodopsins, related to freshwater actinorhodopsins, was found in these organisms. Their genomes suggest a capacity to assimilate C2 compounds, some using the glyoxylate bypass and others with the ethylmalonyl-coenzyme A (CoA) pathway. They are also able to derive energy from dimethylsulfopropionate (DMSP), sulfonate, and carbon monoxide oxidation, all commonly available in the marine habitat. These organisms appear to be prevalent in the deep photic zone at or around the DCM. The presence of sister clades to the marine Acidimicrobiales in freshwater aquatic habitats provides a new example of marine-freshwater transitions with potential evolutionary insights. Despite several studies showing the importance and abundance of planktonic Actinobacteria in the marine habitat, a representative genome was only recently described. In order to expand the genomic repertoire of marine Actinobacteria, we describe here the first Acidimicrobidae genomes of marine origin and provide insights about their ecology. They display metabolic versatility in the acquisition of carbon and appear capable of utilizing diverse sources of energy. One of the genomes harbors a new kind of rhodopsin related to the actinorhodopsin clade of freshwater origin that is widespread in the oceans. Our data also support their preference to inhabit the deep chlorophyll maximum and the deep photic zone. This work contributes to the perception of marine actinobacterial groups as important players in the marine environment with distinct and

2018-03-01

To examine the potential effects of lifestyle factors on male reproductive health. Evidence of a global decline in human sperm quality over recent decades has been accumulating. Environmental, occupational, and modifiable lifestyle factors may contribute to this decline. This review focuses on key lifestyle factors that are associated with male infertility such as smoking cigarettes, alcohol intake, use of illicit drugs, obesity, psychological stress, advanced paternal age, dietary practices, and coffee consumption. Other factors such as testicular heat stress, intense cycling training, lack of sleep and exposure to electromagnetic radiation from mobile phone use are briefly discussed. A comprehensive literature search was performed to identify and synthesise all relevant information, mainly from within the last decade, on the major lifestyle factors associated with male infertility and semen quality. Database searches were limited to reports published in English only. A manual search of bibliographies of the reports retrieved was conducted to identify additional relevant articles. In all, 1012 articles were identified from the database search and after reviewing the titles and abstract of the reports, 104 articles met the inclusion criteria. Of these, 30 reports were excluded as the full-text could not be retrieved and the abstract did not have relevant data. The remaining 74 reports were reviewed for data on association between a particular lifestyle factor and male infertility and were included in the present review. The major lifestyle factors discussed in the present review are amongst the multiple potential risk factors that could impair male fertility. However, their negative impact may well be mostly overcome by behaviour modification and better lifestyle choices. Greater awareness and recognition of the possible impact of these lifestyle factors are important amongst couples seeking conception.

Lifestyle modification programs are different but typically include both nutritional aspects and physical activity as main domains with different behavioral and/or psychological strategies designed to affect change. A fundamental role in modifying unhealthy habits is played by personal motivation for change. The present study sought to investigate, in a group of 100 overweight/obese outpatients with and/or without TMD2, treatment seeking, the effect of an intensive lifestyle program on medical measures and motivational profile for physical activity (PA) and healthy nutrition (NUTR). Subjects participated in an intensive multidisciplinary lifestyle intervention at C.U.R.I.A.MO. Before and after the intervention, patients received a comprehensive evaluation of their clinical, anthropometric, and metabolic states and motivation to lifestyle changes. Data showed differences before and after intervention in both medical and motivational measures. Before the intervention patients reported to be ready, open, and determined to change and gave importance to healthy habits. After the intervention patients continued to be determined but increased the actions toward the change showing a higher degree of maintenance and of acquisition of habits especially in the physical domain of the new lifestyle. Data support the notion that the motivation should be followed during all the lifestyle interventions to support the change on both domains of the lifestyle program.

Since a history of stroke or transient ischaemic attack is a major risk factor for a recurrent event, lifestyle counselling during the hospital phase is an essential component of treatment and may increase the probability of lifestyle change. To study the effect of risk factor-targeted lifestyle counselling intervention on working-age stroke patients' adherence to lifestyle changes. A quasi-experimental, nonequivalent control group pretest-post-test design. Stroke patients in an acute neurological unit were divided into a control group (n = 75) receiving standard counselling and an experimental group (n = 75) receiving risk factor-targeted counselling. Lifestyle data and clinical outcomes were collected at hospital between January 2010 and October 2011, while data on adherence to lifestyle changes 3, 6, and 12 months after discharge. The baseline lifestyle habits did not differ significantly other than in alcohol behaviour. Both groups increased their intake, but the intervention group to a lesser degree. However, the experimental group significantly lost their weight for the first 3 and 6 months; at 3 months reduction in cigarette consumption and at 6 months significant increases in smoking cessation were also achieved. All improved some of their lifestyle habits. Intervention was associated with support from nurses as well as from family and friends. Adherence scores were higher in the experimental group. Some short-term advantages in lifestyle habits due to the intervention were noted. Participants in both groups improved some of their lifestyle habits. © 2016 Nordic College of Caring Science.

Full Text Available Research Question (RQ: What kind of lifestyle do the principals and entrepreneurs lead? Does the lifestyle of principals and entrepreneurs influence burnout? Purpose: To find out, based on the results of a questionnaire, what kind of lifestyle both researched groups lead. Does lifestyle have an influence on the occurrence of the phenomenon of burnout. Method: We used the method of data collection by questionnaire. Acquired data were analyzed using SPSS, descriptive and inference statistics. Results: Results showed, that both groups lead a similar lifestyle and that lifestyle influences burnout with principals, as well as entrepreneurs. Organization: School principals and entrepreneurs are the heads of individual organizations or companies, the goal of which is success. To be successful in their work, they must adapt their lifestyle, which can be healthy or unhealthy. If their lifestyle is unhealthy, it can lead to burnout. Society: With results of the questionnaire we would like to answer the question about the lifestyle of both groups and its influence on the occurrence of burnout. Originality: The study of lifestyle and the occurrence of burnout in these two groups is the first study in this area. Limitations/Future Research: In continuation, research groups could be submitted to the research fields of effort physiology and tracking of certain haematological parameters, such as cholesterol, blood sugar and stress hormones - adrenaline, noradrenalin, cortisol. Thus, we could carry out an even more in depth research of the connection between lifestyle and burnout.

Full Text Available Esterases catalyze the hydrolysis of ester bonds in fatty acid esters with short-chain acyl groups. Due to the widespread applications of lipolytic enzymes in various industrial applications, there continues to be an interest in novel esterases with unique properties. Marine ecosystems have long been acknowledged as a significant reservoir of microbial biodiversity and in particular of bacterial enzymes with desirable characteristics for industrial use, such as for example cold adaptation and activity in the alkaline pH range. We employed a functional metagenomic approach to exploit the enzymatic potential of one particular marine ecosystem, namely the microbiome of the deep sea sponge Stelletta normani. Screening of a metagenomics library from this sponge resulted in the identification of a number of lipolytic active clones. One of these encoded a highly, cold-active esterase 7N9, and the recombinant esterase was subsequently heterologously expressed in Escherichia coli. The esterase was classified as a type IV lipolytic enzyme, belonging to the GDSAG subfamily of hormone sensitive lipases. Furthermore, the recombinant 7N9 esterase was biochemically characterized and was found to be most active at alkaline pH (8.0 and displays salt tolerance over a wide range of concentrations. In silico docking studies confirmed the enzyme's activity toward short-chain fatty acids while also highlighting the specificity toward certain inhibitors. Furthermore, structural differences to a closely related mesophilic E40 esterase isolated from a marine sediment metagenomics library are discussed.

We have conducted a series studies in the South China Sea (SCS), investigating phytoplankton, sea surface temperature (SST), fishery data and related factors before, during, and after typhoon. Satellite remote sensing and in situ observation data obtained from research cruise were applied. Our study showed that typhoon can support nutrients to surface phytoplankton by inducing upwelling and vertical mixing, and typhoon rain can also nourish marine phytoplankton; both typhoon winds and rain can enhance production of marine phytoplankton. Slow-moving typhoon induced phytoplankton blooms of higher Chlorophyll-a (Chl-a), the strong typhoon induced phytoplankton blooms of a large area. We conservatively estimate that typhoon periods may account for 3.5% of the annual primary production in the oligotrophic SCS. It indicated that one typhoon may induce transport of nutrient-rich water from depth and from the coast to offshore regions, nourishing phytoplankton biomass. More observations confirmed that typhoon can induce cold eddy, and cold eddy can support eddy-shape phytoplankton bloom by upwelling. We have suggested a new index to evaluate typhoon impact on marine ecosystem and environment. This is the first time to report moving eddies and eddy-shape phytoplankton blooms associated with tropical cyclone, the relationship among tropical cyclone, cold eddy upwelling and eddy-shape phytoplankton bloom may give some viewpoint on the tropical cyclone's affection on the mesoscale circulation.

Full Text Available Combined lifestyle interventions (CLIs can be effective in reducing weight and improving lifestyle-related behaviours but it is unclear how CLIs can best be implemented in practice in order to achieve sustained lifestyle changes. The Coaching on Lifestyle programme (CooL is a CLI in the Netherlands, in which professional lifestyle coaches counsel adults and children (and/or their parents who are obese or at high risk of obesity to achieve a sustained healthier lifestyle. The CooL intervention consists of group and individual sessions addressing the topics of physical activity, dietary behaviours, sleep and stress. Our longitudinal one-group pre-post study aimed to identify lifestyle changes among participants (adults, children and their parents at 8 and 18 months after initiation. We assessed constructs ranging from motivation and behaviour-specific cognitions to behaviours and health outcomes. Positive and sustained changes among adults were found regarding perceived autonomy, motivation, perceived barriers, lifestyle behaviours, quality of life and weight. Among children and their parents, few improvements were found regarding behaviours and quality of life. CooL has been successful in coaching adult participants towards sustained behavioural change during the intervention period. Mixed results and smaller effect sizes were found for children and their parents.

For conclusion we found a pervasive preference for lifestyle changes over medical treatment when individuals were promised the same benefits. Lifestyle risk factors and socioeconomic characteristics were associated with preference for lifestyle changes as well as belief in ability to maintain lifestyle changes. For health professionals risk communication should not only focus on patient preferences but also on patients' beliefs in their own ability to initiate lifestyle changes and possible barriers against maintaining changes.

2015-01-01

Pressure ulcers (PrUs) are a major burden to patients with spinal cord injury (SCI), affecting their psychological, physical, and social well-being. Lifestyle choices are thought to contribute to the risk of developing PrUs. This article focuses on the interaction between lifestyle choices and the development of PrUs in community settings among participants in the University of Southern California–Rancho Los Amigos National Rehabilitation Center Pressure Ulcer Prevention Study (PUPS II), a randomized controlled trial of a lifestyle intervention for adults with SCI. We conducted a secondary cross-case analysis of treatment notes of 47 PUPS II participants and identified four patterns relating PrU development to lifestyle changes: positive PrU changes (e.g., healing PrUs) with positive lifestyle changes, negative or no PrU changes with positive lifestyle changes, positive PrU changes with minor lifestyle changes, and negative or no PrU changes with no lifestyle changes. We present case studies exemplifying each pattern. PMID:25553751

Cold injuries.

Kruse, R J

1995-01-01

There are two categories of cold injury. The first is hypothermia, which is a systemic injury to cold, and the second is frostbite, which is a local injury. Throughout history, entire armies, from George Washington to the Germans on the Russian Front in World War II, have fallen prey to prolonged cold exposure. Cold injury is common and can occur in all seasons if ambient temperature is lower than the core body temperature. In the 1985 Boston Marathon, even though it was 76 degrees and sunny, there were 75 runners treated for hypothermia. In general, humans adapt poorly to cold exposure. Children are at particular risk because of their relatively greater surface area/body mass ratio, causing them to cool even more rapidly than adults. Because of this, the human's best defense against cold injury is to limit his/her exposure to cold and to dress appropriately. If cold injury has occurred and is mild, often simple passive rewarming such as dry blankets and a warm room are sufficient treatment.

Major climatic changes in the Pleistocene had significant effects on marine organisms and the environments in which they lived. The presence of divergent patterns of demographic history even among phylogenetically closely-related species sharing climatic changes raises questions as to the respective influence of species-specific traits on population structure. In this work we tested whether the lifestyle of Antarctic notothenioid benthic and pelagic fish species from the Southern Ocean influenced the concerted population response to Pleistocene climatic fluctuations. This was done by a comparative analysis of sequence variation at the cyt b and S7 loci in nine newly sequenced and four re-analysed species. We found that all species underwent more or less intensive changes in population size but we also found consistent differences between demographic histories of pelagic and benthic species. Contemporary pelagic populations are significantly more genetically diverse and bear traces of older demographic expansions than less diverse benthic species that show evidence of more recent population expansions. Our findings suggest that the lifestyles of different species have strong influences on their responses to the same environmental events. Our data, in conjunction with previous studies showing a constant diversification tempo of these species during the Pleistocene, support the hypothesis that Pleistocene glaciations had a smaller effect on pelagic species than on benthic species whose survival may have relied upon ephemeral refugia in shallow shelf waters. These findings suggest that the interaction between lifestyle and environmental changes should be considered in genetic analyses.

Lifestyle hotels: New paradigm of modern hotel industry

Full Text Available The practice of modern hotel industry introduced to professional community the term 'lifestyle' hotel. The paper deals with the essential meaning of this term. This raises the question of the difference between the lifestyle and boutique hotels which are in practice often identified. The paper aims to resolve the basic dilemma - whether lifestyle hotel can be treated as a special type of hotel, or all types of hotels under certain conditions can fit into a group called 'lifestyle'. Closer defining of the term 'lifestyle' is a starting point for further discussion. This paper makes an attempt to overcome the uncritical use of the term 'lifestyle' in tourism and hospitality practice. Providing a clearer definition is necessary to establish standards for the typology of lifestyle hotels. These standards are primarily based on the criteria of market segmentation. Among them, psychographic criteria occupy a special place. To make lifestyle hotel more than a promotional slogan, it is necessary to confirm its market position. This means identifying specific target groups differentiated according to the main features of the lifestyle.

Several studies have identified negative health lifestyles as a primary determinant of the mortality crisis in Europe's post-communist states, but little is known about Ukraine. In order to address this gap in the literature, this paper provides data on Ukrainian health lifestyles. Data were collected by face-to-face interviews in the households (N = 2 400) of a random sample of respondents in Ukraine in November, 2001. The sample was selected using multi-stage random sampling with stratification by region and area (urban/rural). Data were analyzed using logistic regression. Male gender was found to be the most powerful single predictor of negative health lifestyles as shown in the results for frequent drinking, heavy vodka use at one occasion, smoking, and diet. Males rated their health status better than females, but over one-third of the males and one-half of the females rated their health status as rather bad or bad. Gender and class differences in health lifestyle practices appear to be key variables, with working-class males showing the most negative practices. The results for health status suggest that the overall level of health in Ukraine is not good.

Unhealthy lifestyle characteristics (i.e., physical inactivity, excess body mass, poor diet, and smoking) as well as associated poor health metrics (i.e., dyslipidemia, hyperglycemia, and hypertension) are the primary reasons for the current non-communicable disease crisis. Compared to those with the poorest of lifestyles and associated health metrics, any movement toward improving lifestyle and associated health metrics improves health outcomes. To address the non-communicable disease crisis we must: 1) acknowledge that healthy lifestyle (HL) interventions are a potent medicine; and 2) move toward a healthcare system that embraces primordial as much as, if not more than, secondary prevention with a heavy focus on HL medicine. This article introduces the Healthy Lifestyle Practitioner, focused on training health professionals to deliver HL medicine.

Individuals with low socioeconomic status (SES) are generally less well reached through lifestyle interventions than individuals with higher SES. The aim of this study was to identify opportunities for adapting lifestyle interventions in such a way that they are more appealing for individuals with low SES. To this end, the study provides insight into perspectives of groups with different socioeconomic positions regarding their current eating and physical activity behaviour; triggers for lifestyle change; and ways to support lifestyle change. Data were gathered in semi-structured focus group interviews among low SES (four groups) and high SES (five groups) adults. The group size varied between four and nine participants. The main themes discussed were perceptions and experiences of healthy eating, physical activity and lifestyle advice. Interviews were transcribed verbatim and a thematic approach was used to analyse the data. In general, three key topics were identified, namely: current lifestyle is logical for participants given their personal situation; lifestyle change is prompted by feedback from their body; and support for lifestyle change should include individually tailored advice and could profit from involving others. The perceptions of the low SES participants were generally comparable to the perceptions shared by the high SES participants. Some perceptions were, however, especially shared in the low SES groups. Low SES participants indicated that their current eating behaviour was sometimes affected by cost concerns. They seemed to be especially motivated to change their lifestyle when they experienced health complaints, but were rather hesitant to change their lifestyle for preventive purposes. Regarding support for lifestyle change, low SES participants preferred to receive advice in a group rather than on their own. For physical activities, groups should preferably consist of persons of the same age, gender or physical condition. To motivate

Marine free living copepods can survive harsh periods and cope with seasonal fluctuations in environmental conditions using resting eggs (embryonic dormancy). Laboratory experiments show that temperature is the common driver for resting egg production. Hence, we hypothesize (i) that seasonal...... temperature variation, rather than variation in food abundance is the main driver for the occurrence of the resting eggs strategy in marine and estuarine copepod species; and (ii) that the thermal boundaries of the distribution determine where resting eggs are produced and whether they are produced to cope...... with warm or cold periods. We compile literature information on the occurrence of resting egg production and relate this to spatio-temporal patterns in sea surface temperature and chlorophyll a concentration obtained from satellite observations. We find that the production of resting eggs has been reported...

Full Text Available Nowdays, a degree of contamination by heavy metals can be observed in the environment. Heavy metals have serious effects on all living organisms because they can accumulate in lethal or sublethal concentrations in the various parts of food chain and so they can cause different health problems like cardiovascular and cancer diseases. Marine fish and animals are one of the bigges source of mercury in human food. Therefore this work is focused to the rate of mercury content in muscle tisuues of marine fish and animals. We analyzed mainly frozen or otherwise preserved marine fish and animals that were purchased in retail network in Slovakia. Mercury content in samples was analyzed by cold vapor AAS with mercury analyser AMA254. The contents of mercury in analysed samples were in the interval 0.0057 – 0,697 mg.kg-1. Our results shows, that no analyzed samples of marine fish and animals had over-limit concetration of Hg, so they are safe for human nutrition.

2013-01-01

So far many worksite lifestyle or health promotion programmes have shown only moderate evidence of effectiveness and cost-effectiveness. However, participation in work is in itself an important determinant of health. For this reason ensuring of fitting work and sustained workability should be an aspect of health policy. Workers' health is not only determined by their working environment but also by health practices and lifestyle factors. Under certain preconditions (e.g. on a voluntary basis, confidentiality, integration with health protection) lifestyle interventions during work time can contribute to a healthier working population. As such programmes may result in financial and social benefits for employers, they should be partly responsible for paying the costs. From a societal perspective, governmental commitment to a preventive policy and the involvement of health and income insurance companies are also required.

Lifestyle factors in U.S. residential electricity consumption

International Nuclear Information System (INIS)

Sanquist, Thomas F.; Orr, Heather; Shui Bin; Bittner, Alvah C.

2012-01-01

A multivariate statistical approach to lifestyle analysis of residential electricity consumption is described and illustrated. Factor analysis of selected variables from the 2005 U.S. Residential Energy Consumption Survey (RECS) identified five lifestyle factors reflecting social and behavioral patterns associated with air conditioning, laundry usage, personal computer usage, climate zone of residence, and TV use. These factors were also estimated for 2001 RECS data. Multiple regression analysis using the lifestyle factors yields solutions accounting for approximately 40% of the variance in electricity consumption for both years. By adding the household and market characteristics of income, local electricity price and access to natural gas, variance accounted for is increased to approximately 54%. Income contributed ∼1% unique variance to the models, indicating that lifestyle factors reflecting social and behavioral patterns better account for consumption differences than income. Geographic segmentation of factor scores shows distinct clusters of consumption and lifestyle factors, particularly in suburban locations. The implications for tailored policy and planning interventions are discussed in relation to lifestyle issues. - Highlights: ► Illustrates lifestyle analysis of residential electricity consumption. ► Lifestyle factors based on social and behavioral decisions and equipment use. ► Regression models using lifestyle factors account for 40% of consumption variance. ► Lifestyle factors are stable over time when applied to other data sets. ► Energy reduction opportunities are identified by segmentation analysis.

A cold plate, an electronic assembly including a cold plate, and a method for forming a cold plate are provided. The cold plate includes an interface plate and an opposing plate that form a plenum. The cold plate includes a plurality of active areas arranged for alignment over respective heat generating portions of an electronic assembly, and non-active areas between the active areas. A cooling fluid flows through the plenum. The plenum, at the non-active areas, has a reduced width and/or reduced height relative to the plenum at the active areas. The reduced width and/or height of the plenum, and exterior dimensions of cold plate, at the non-active areas allow the non-active areas to flex to accommodate surface variations of the electronics assembly. The reduced width and/or height non-active areas can be specifically shaped to fit between physical features of the electronics assembly.

The study was performed on 245 Slovene railroad workers (168 of them blue-collar ones. The great majority (66.9% were found to be overweight or obese (BMI 25 or more, with no significant difference between blue- and white-collar workers. The great majority of them were in general aware of having unhealthy nutrition and an unhealthy lifestyle.

Thus the effort needed to overcome constraints toward a healthier lifestyle seems to be the key problem: the majority (54.3% would rather choose walking than running or other intensive forms of exercise; they are not ready to do it for more than one hour per day (60%, and they are not ready to give up permanently food that they like and that is considered unhealthy. The differences in motivations for a healthy lifestyle between blue- and white-collar workers were not significant at the 0.05 level. Further research in this field is needed; however, it seems that the methods of efficient marginal modifications of lifestyle are required.

Fossil methane from the large and dynamic marine gas hydrate reservoir has the potential to influence oceanic and atmospheric carbon pools. However, natural radiocarbon (14C) measurements of gas hydrate methane have been extremely limited, and their use as a source and process indicator has not yet been systematically established. In this study, gas hydrate-bound and dissolved methane recovered from six geologically and geographically distinct high-gas-flux cold seeps was found to be 98 to 100% fossil based on its 14C content. Given this prevalence of fossil methane and the small contribution of gas hydrate (??? 1%) to the present-day atmospheric methane flux, non-fossil contributions of gas hydrate methane to the atmosphere are not likely to be quantitatively significant. This conclusion is consistent with contemporary atmospheric methane budget calculations. In combination with ??13C- and ??D-methane measurements, we also determine the extent to which the low, but detectable, amounts of 14C (~ 1-2% modern carbon, pMC) in methane from two cold seeps might reflect in situ production from near-seafloor sediment organic carbon (SOC). A 14C mass balance approach using fossil methane and 14C-enriched SOC suggests that as much as 8 to 29% of hydrate-associated methane carbon may originate from SOC contained within the upper 6??m of sediment. These findings validate the assumption of a predominantly fossil carbon source for marine gas hydrate, but also indicate that structural gas hydrate from at least certain cold seeps contains a component of methane produced during decomposition of non-fossil organic matter in near-surface sediment.

Full Text Available Climatically extreme weather events often drive long-term ecological responses of ecosystems. By disrupting the important symbiosis with zooxanthellae, Marine Cold Spells (MCS can cause bleaching and mortality in tropical and subtropical scleractinian corals. Here we report on the effects of a severe MCS on high latitude corals, where we expected to find bleaching and mortality. The MCS took place off the coast of Perth (32°S, Western Australia in 2016. Bleaching was assessed before (2014 and after (2017 the MCS from surveys of permanent plots, and with timed bleaching searches. Temperature data was recorded with in situ loggers. During the MCS temperatures dipped to the coldest recorded in ten years (15.3°C and periods of <17°C lasted for up to 19 days. Only 4.3% of the surveyed coral colonies showed signs of bleaching. Bleaching was observed in 8 species where those most affected were Plesiastrea versipora and Montipora mollis. These findings suggest that high latitude corals in this area are tolerant of cold stress and are not persisting near a lethal temperature minimum. It has not been established whether other environmental conditions are limiting these species, and if so, what the implications are for coral performance on these reefs in a warmer future.

Recognition is growing of the influence of the workplace on lifestyle, and its consequent effect on health. This relation between work, lifestyle and health is highly relevant to the North Sea oil and gas industry where employment often demands the adoption of, and exposure to, a lifestyle far removed from that of comparable onshore occupations. This risk factors for Coronary Heart Disease (CHD) which is the largest single cause of premature adult death in Great Britain can be classified according to those that are immodifiable (eg gender), and those that result from lifestyle choices (eg smoking, diet). The demographic profile (predominant gender, age group and nationality) of the offshore workforce is thought to place it in an inherently high risk group for CHD. Anecdotal evidence further suggests that the offshore lifestyle may expose the workforce to increased CHD risk factors, particularly in terms of diet, tobacco consumption and exercise habits. The lifestyle of offshore workers may be considered as a form of occupational hazard, comparable with recognised occupational risks. A sample of 500 offshore workers undertaking survival training were surveyed using a structured questionnaire to investigate aspects of their lifestyle. Subjects compared their smoking, dietary and exercise habits between periods onshore and offshore. Analysis of results pointed to some significant differences in lifestyle between these two periods. Additional factors such as occupation status (whether directly employed or contracted), onshore alcohol consumption, and subjects` perception of job and family satisfaction were also analysed in relation to lifestyle. Results indicate the potential benefits of health promotion intervention. Opportunities for such intervention are identified and discussed within the context of caring for an efficient utilisation of the Offshore Industry`s human resources. (Author)

Senior's lifestyle and their store choice

Lesakova Dagmar

2014-01-01

Full Text Available To attract and retain customers, an understanding of their motives and reasons for selecting particular food and grocery store is needed. This is of particular importance in the growing segment of seniors. The size of the senior's market demands a better understanding of the older consumer. The aim of our study is to identify psychographic characteristics of the elderly consumer, and to indicate the lifestyle groups and the relationship between these groups and retail store attributes. Differences in the motives for patronizing specific food stores are analyzed for lifestyle groups. We use the lifestyle as a segmentation variable in the diverse population of seniors for the reason, that the lifestyle of the elderly provides more valuable information than chronological age alone. This information can be used by retailers to improve marketing strategies in order to appeal to a target group of senior shoppers. Empirical research is based on a self-administrated questionnaire aimed on the identification of the lifestyle characteristics and retail store attributes of the consumers in 65+ age, used for the choice of food purchasing retail stores. Lifestyles characteristics were measured by the respondents activities, interests and opinions (AIO. The results of the research indicate that there are differences among the lifestyle groups with significant differences in attitudes towards quality of products or internal store environment. Our research demonstrates the value of psychographic information over age alone regarding the patronage factors in store selection. Our study is a part of the research project VEGA 1/0612/12 'Determinants of the size, structure and tendences in the individual consumption of seniors'.

There is a general lack of information on the dispersal and genetic structuring for populations of small-sized deep-water taxa, including free-living nematodes which inhabit and dominate the seafloor sediments. This is also true for unique and scattered deep-sea habitats such as cold seeps. Given the limited dispersal capacity of marine nematodes, genetic differentiation between such geographically isolated habitat patches is expected to be high. Against this background, we examined genetic variation in both mitochondrial (COI) and nuclear (18S and 28S ribosomal) DNA markers of 333 individuals of the genus Sabatieria, abundantly present in reduced cold-seep sediments. Samples originated from four Eastern Mediterranean cold seeps, separated by hundreds of kilometers, and one seep in the Southeast Atlantic. Individuals from the Mediterranean and Atlantic were divided into two separate but closely-related species clades. Within the Eastern Mediterranean, all specimens belonged to a single species, but with a strong population genetic structure (Φ ST  = 0.149). The haplotype network of COI contained 19 haplotypes with the most abundant haplotype (52% of the specimens) shared between all four seeps. The number of private haplotypes was high (15), but the number of mutations between haplotypes was low (1-8). These results indicate intermediary gene flow among the Mediterranean Sabatieria populations with no evidence of long-term barriers to gene flow. The presence of shared haplotypes and multiple admixture events indicate that Sabatieria populations from disjunct cold seeps are not completely isolated, with gene flow most likely facilitated through water current transportation of individuals and/or eggs. Genetic structure and molecular diversity indices are comparable to those of epiphytic shallow-water marine nematodes, while no evidence of sympatric cryptic species was found for the cold-seep Sabatieria.

What the body temperature and thermoregulation processes of extinct vertebrates were are central questions for understanding their ecology and evolution. The thermophysiologic status of the great marine reptiles is still unknown, even though some studies have suggested that thermoregulation may have contributed to their exceptional evolutionary success as apex predators of Mesozoic aquatic ecosystems. We tested the thermal status of ichthyosaurs, plesiosaurs, and mosasaurs by comparing the oxygen isotope compositions of their tooth phosphate to those of coexisting fish. Data distribution reveals that these large marine reptiles were able to maintain a constant and high body temperature in oceanic environments ranging from tropical to cold temperate. Their estimated body temperatures, in the range from 35 degrees +/- 2 degrees C to 39 degrees +/- 2 degrees C, suggest high metabolic rates required for predation and fast swimming over large distances offshore.

Prevention of Dementia: Focus on Lifestyle

Directory of Open Access Journals (Sweden)

Maria Cristina Polidori

2010-01-01

Full Text Available The objective of this paper is to summarize current knowledge on the possible advantages of lifestyle interventions, with particular attention to physical fitness, cognitive activity, leisure and social activity as well as nutrition. There is a large amount of published papers providing partial evidence and asserting the need for immediate, appropriate preventive lifestyle measures against dementia and AD development. Nevertheless, there are currently great difficulties in drafting effective guidelines in this field. This depends mainly upon lack of randomized controlled trials assessing benefits versus risks of particular lifestyle interventions strategies. However, due to the rapid increase of dementia burden, lifestyle factors and their amelioration should be already made part of decision making in light of their health-maintaining effects while awaiting for results of well-designed large prospective cohort studies in dementia.

Full Text Available This research analyzes gender differences observed in different aspects of adolescent lifestyles, such as physical activities and sports, involvement in extracurricular activities, use of ICT’s, time spent with friends and time spent studying, substance use, and sleep-related routines. Bearing this in mind, we analyzed differences by year and gender in a sample of 2400 adolescents, 55.5 percent girls and 44.5 percent of boys, aged between 12 and 17 (mean age =14.73 and SD = 1.24 in 20 schools from Andalusia. The results from correlation analysis, ANOVA, and Tukey test confirm significant correlations between most variables making up lifestyle, most of them positive except those related to substance use (most correlations were negative. We also found significant gender differences in lifestyles: 10 out of the 15 variables analyzed have significant gender differences. A significant negative correlation with age was found in a number of variables making up healthy lifestyles, such as the practice of sport and physical activity, participation in extracurricular activities and sleep.

Mapping of Cold-Water Coral Carbonate Mounds Based on Geomorphometric Features: An Object-Based Approach

Directory of Open Access Journals (Sweden)

Markus Diesing

2018-01-01

Full Text Available Cold-water coral reefs are rich, yet fragile ecosystems found in colder oceanic waters. Knowledge of their spatial distribution on continental shelves, slopes, seamounts and ridge systems is vital for marine spatial planning and conservation. Cold-water corals frequently form conspicuous carbonate mounds of varying sizes, which are identifiable from multibeam echosounder bathymetry and derived geomorphometric attributes. However, the often-large number of mounds makes manual interpretation and mapping a tedious process. We present a methodology that combines image segmentation and random forest spatial prediction with the aim to derive maps of carbonate mounds and an associated measure of confidence. We demonstrate our method based on multibeam echosounder data from Iverryggen on the mid-Norwegian shelf. We identified the image-object mean planar curvature as the most important predictor. The presence and absence of carbonate mounds is mapped with high accuracy. Spatially-explicit confidence in the predictions is derived from the predicted probability and whether the predictions are within or outside the modelled range of values and is generally high. We plan to apply the showcased method to other areas of the Norwegian continental shelf and slope where multibeam echosounder data have been collected with the aim to provide crucial information for marine spatial planning.

Cold urticaria. Dissociation of cold-evoked histamine release and urticara following cold challenge.

Keahey, T M; Greaves, M W

1980-02-01

Nine patients with acquired cold urticaria were studied to assess the effects of beta-adrenergic agents, xanthines, and corticosteroids on cold-evoked histamine release from skin in vivo. The patients, in all of whom an immediate urticarial response developed after cooling of the forearm, demonstrated release of histamine into the venous blood draining that forearm. Following treatment with aminophylline and albuterol in combination or prednisone alone, suppression of histamine release occurred in all but one patient. In some patients, this was accompanied by a subjective diminution in pruritus or buring, but there was no significant improvement in the ensuing edema or erythema. In one patient, total suppression of histamine release was achieved without any effect on whealing and erythema in response to cold challenge. Our results suggest that histamine is not central to the pathogenesis of vascular changes in acquired cold urticaria.

Lifestyle and accidents among young drivers.

Gregersen, N P; Berg, H Y

1994-06-01

This study covers the lifestyle component of the problems related to young drivers' accident risk. The purpose of the study is to measure the relationship between lifestyle and accident risk, and to identify specific high-risk and low-risk groups. Lifestyle is measured through a questionnaire, where 20-year-olds describe themselves and how often they deal with a large number of different activities, like sports, music, movies, reading, cars and driving, political engagement, etc. They also report their involvement in traffic accidents. With a principal component analysis followed by a cluster analysis, lifestyle profiles are defined. These profiles are finally correlated to accidents, which makes it possible to define high-risk and low-risk groups. The cluster analysis defined 15 clusters including four high-risk groups with an average overrisk of 150% and two low-risk groups with an average underrisk of 75%. The results are discussed from two perspectives. The first is the importance of theoretical understanding of the contribution of lifestyle factors to young drivers' high accident risk. The second is how the findings could be used in practical road safety measures, like education, campaigns, etc.

Spatial and temporal distributions of Martian north polar cold spots before, during, and after the global dust storm of 2001

In the 1970s, Mariner and Viking observed features in the Mars northern polar region that were a few hundred kilometers in diameter with 20 fj,m brightness temperatures as low as 130 K (considerably below C02 ice sublimation temperatures). Over the past decade, studies have shown that these areas (commonly called "cold spots") are usually due to emissivity effects of frost deposits and occasionally to active C02 snowstorms. Three Mars years of Mars Global Surveyor Thermal Emission Spectrometer data were used to observe autumn and wintertime cold spot activity within the polar regions. Many cold spots formed on or near scarps of the perennial cap, probably induced by adiabatic cooling due to orographic lifting. These topographically associated cold spots were often smaller than those that were not associated with topography. We determined that initial grain sizes within the cold spots were on the order of a few millimeters, assuming the snow was uncontaminated by dust or water ice. On average, the half-life of the cold spots was 5 Julian days. The Mars global dust storm in 2001 significantly affected cold spot activity in the north polar region. Though overall perennial cap cold spot activity seemed unaffected, the distribution of cold spots did change by a decrease in the number of topographically associated cold spots and an increase in those not associated with topography. We propose that the global dust storm affected the processes that form cold spots and discuss how the global dust storm may have affected these processes. ?? 2009 by the American Geophysical Union.

Ecohydrodynamics of cold-water coral reefs: a case study of the Mingulay Reef Complex (western Scotland.

Directory of Open Access Journals (Sweden)

Juan Moreno Navas

Full Text Available Ecohydrodynamics investigates the hydrodynamic constraints on ecosystems across different temporal and spatial scales. Ecohydrodynamics play a pivotal role in the structure and functioning of marine ecosystems, however the lack of integrated complex flow models for deep-water ecosystems beyond the coastal zone prevents further synthesis in these settings. We present a hydrodynamic model for one of Earth's most biologically diverse deep-water ecosystems, cold-water coral reefs. The Mingulay Reef Complex (western Scotland is an inshore seascape of cold-water coral reefs formed by the scleractinian coral Lophelia pertusa. We applied single-image edge detection and composite front maps using satellite remote sensing, to detect oceanographic fronts and peaks of chlorophyll a values that likely affect food supply to corals and other suspension-feeding fauna. We also present a high resolution 3D ocean model to incorporate salient aspects of the regional and local oceanography. Model validation using in situ current speed, direction and sea elevation data confirmed the model's realistic representation of spatial and temporal aspects of circulation at the reef complex including a tidally driven current regime, eddies, and downwelling phenomena. This novel combination of 3D hydrodynamic modelling and remote sensing in deep-water ecosystems improves our understanding of the temporal and spatial scales of ecological processes occurring in marine systems. The modelled information has been integrated into a 3D GIS, providing a user interface for visualization and interrogation of results that allows wider ecological application of the model and that can provide valuable input for marine biodiversity and conservation applications.

Global habitat suitability for framework-forming cold-water corals.

Directory of Open Access Journals (Sweden)

Andrew J Davies

Full Text Available Predictive habitat models are increasingly being used by conservationists, researchers and governmental bodies to identify vulnerable ecosystems and species' distributions in areas that have not been sampled. However, in the deep sea, several limitations have restricted the widespread utilisation of this approach. These range from issues with the accuracy of species presences, the lack of reliable absence data and the limited spatial resolution of environmental factors known or thought to control deep-sea species' distributions. To address these problems, global habitat suitability models have been generated for five species of framework-forming scleractinian corals by taking the best available data and using a novel approach to generate high resolution maps of seafloor conditions. High-resolution global bathymetry was used to resample gridded data from sources such as World Ocean Atlas to produce continuous 30-arc second (∼1 km(2 global grids for environmental, chemical and physical data of the world's oceans. The increased area and resolution of the environmental variables resulted in a greater number of coral presence records being incorporated into habitat models and higher accuracy of model predictions. The most important factors in determining cold-water coral habitat suitability were depth, temperature, aragonite saturation state and salinity. Model outputs indicated the majority of suitable coral habitat is likely to occur on the continental shelves and slopes of the Atlantic, South Pacific and Indian Oceans. The North Pacific has very little suitable scleractinian coral habitat. Numerous small scale features (i.e., seamounts, which have not been sampled or identified as having a high probability of supporting cold-water coral habitat were identified in all ocean basins. Field validation of newly identified areas is needed to determine the accuracy of model results, assess the utility of modelling efforts to identify vulnerable marine

This study was conducted to investigate relationships of self-identified cold tolerance and cold-induced vasodilatation (CIVD) in the finger. Nine males and 34 females participated in the following 2 tests: a CIVD test and a self-reported survey. The CIVD test was conducted 30-min cold-water immersion (3.8 ± 0.3 °C) of the middle finger at an air temperature of 27.9 ± 0.1 °C. The self-reported questionnaire consisted of 28 questions about whole and local body cold and heat tolerances. By a cluster analysis on the survey results, the participants were divided into two groups: high self-identified cold tolerance (HSCT, n = 25) and low self-identified cold tolerance (LSCT, n = 18). LSCT had lower self-identified cold tolerance ( P cold or heat tolerance had relationships with cold tolerance index, T max, and amplitude ( P cold tolerance classified through a standardized survey could be a good index to predict physiological cold tolerance.

Full Text Available Objective: Sedentary lifestyle is a major risk factor for physical and mental problems, such as cardiovascular, musculoskeletal diseases, and psychological stress. About 60% of the world’s population is not sufficiently physically active in leisure time or during work and social activities. This study aimed to determine the prevalence of inactive Jordanian adults and describe their demographic and behavioral characteristics. Methods: The study used data from the behavioral risk factors surveillance survey conducted in Jordan in 2007. The sample size was 3654. Respondents who were physically inactive for more than 240 min daily (sleep time not included were considered to have a sedentary lifestyle. Data were analyzed with the program SPSS. Results: The prevalence of a sedentary lifestyle was 82.8% (2965 respondents, with a mean sedentary time of 587 min (95% confidence interval 581–594 min. Among the physically inactive adults, 52.6% were men, one third of them aged 35–44 years. Sedentary lifestyle was reported by 30% of those with a secondary level of education or above. Of those with a sedentary lifestyle, 37.6% were housewives and 37.5% were employees; 66% of them were overweight and obese. Of the physically inactive people, 2.5% had a history of heart failure and 1.3% had a history of cerebrovascular accidents; 57.2% of them tried to engage more in physical activity and almost three quarters of them were interested in improving their dietary habits. Conclusion: Most Jordanian adults have a sedentary lifestyle, which emphasizes that there is a public health problem. Many of them are attempting to lead a healthier lifestyle. Therefore, there is an urgent need to launch an applicable national plan that enables people to practice a healthier lifestyle.

Genotype-dependent Burst of Transposable Element Expression in Crowns of Hexaploid Wheat (Triticum aestivum L. during Cold Acclimation

Debbie Laudencia-Chingcuanco

2012-01-01

Full Text Available The expression of 1,613 transposable elements (TEs represented in the Affymetrix Wheat Genome Chip was examined during cold treatment in crowns of four hexaploid wheat genotypes that vary in tolerance to cold and in flowering time. The TE expression profiles showed a constant level of expression throughout the experiment in three of the genotypes. In winter Norstar, the most cold-hardy of the four genotypes, a subset of the TEs showed a burst of expression after vernalization saturation was achieved. About 47% of the TEs were expressed, and both Class I (retrotransposons and Class II (DNA transposons types were well represented. Gypsy and Copia were the most represented among the retrotransposons while CACTA and Mariner were the most represented DNA transposons. The data suggests that the Vrn-A1 region plays a role in the stage-specific induction of TE expression in this genotype.

Impacts of metal and metal oxide nanoparticles on marine organisms

International Nuclear Information System (INIS)

Baker, Tony J.; Tyler, Charles R.; Galloway, Tamara S.

2014-01-01

Increasing use of metal and metal oxide nanoparticles [Me(O)NPs] in products means many will inevitably find their way into marine systems. Their likely fate here is sedimentation following hetero-aggregation with natural organic matter and/or free anions, putting benthic, sediment-dwelling and filter feeding organisms most at risk. In marine systems, Me(O)NPs can absorb to micro-organisms with potential for trophic transfer following consumption. Filter feeders, especially bivalves, accumulate Me(O)NPs through trapping them in mucus prior to ingestion. Benthic in-fauna may directly ingest sedimented Me(O)NPs. In fish, uptake is principally via the gut following drinking, whilst Me(O)NPs caught in gill mucus may affect respiratory processes and ion transport. Currently, environmentally-realistic Me(O)NP concentrations are unlikely to cause significant adverse acute health problems, however sub-lethal effects e.g. oxidative stresses have been noted in many organisms, often deriving from dissolution of Ag, Cu or Zn ions, and this could result in chronic health impacts. -- Highlights: • Nanoparticle (NP) use increasing, and NPs ultimately discharged to marine systems. • Metal ion dissolution from NPs causes oxidative stress at relevant concentrations. • Bioaccumulation and trophic transfer of NPs likely at all levels of marine food webs. • Biofilms and filter feeders are major NP accumulators, but many Classes lack study. • Current release levels unlikely to cause chronic damage, but may be a future issue. -- Exposure to metal (oxide) nanoparticles causes sub-lethal effects in marine organisms, the extent of which is related principally to the organisms' feeding regime, habitat and lifestyle

Cold-Hearted or Cool-Headed: Physical Coldness Promotes Utilitarian Moral Judgment

Directory of Open Access Journals (Sweden)

Full Text Available In the current study, we examine the effect of physical coldness on personal moral dilemma judgment. Previous studies have indicated that utilitarian moral judgment—sacrificing a few people to achieve the greater good for others—was facilitated when: (1 participants suppressed an initial emotional response and deliberately thought about the utility of outcomes; (2 participants had a high-level construal mindset and focused on abstract goals (e.g., save many; or (3 there was a decreasing emotional response to sacrificing a few. In two experiments, we exposed participants to extreme cold or typical room temperature and then asked them to make personal moral dilemma judgments. The results of Experiment 1 indicated that coldness prompted utilitarian judgment, but the effect of coldness was independent from deliberate thought or abstract high-level construal mindset. As Experiment 2 revealed, coldness facilitated utilitarian judgment via reduced empathic feelings. Therefore, physical coldness did not affect the cool-headed deliberate process or the abstract high-level construal mindset. Rather, coldness biased people toward being cold-hearted, reduced empathetic concern about a sacrificed victim, and facilitated utilitarian moral judgments.

To: (a) establish criteria for defining positive health behaviors and lifestyle; and (b) identify characteristics of adolescents who practice a healthy lifestyle. Responses from a 1998 survey via questionnaire, of 1487 students, from a public high school, Cambridge, Massachusetts, were used to assess correlates of healthy lifestyle choices. Strict and broad assessments of healthy behaviors were defined for students: use of alcohol, tobacco, and illegal drugs; sexual behavior; attempted suicide. Whereas the "strict" criteria included only those adolescents who did not practice any of the behaviors in question, the broad criteria reflected experimentation and moderate risk-taking. The prevalence of positive behaviors was assessed by demographic and student characteristics. In addition, logistic regression models were created to predict determinants of teenagers' healthy lifestyles using both strict and broad definitions. Using strict criteria of healthy lifestyle, significant predictors were being female, born outside the United States, higher academic performance, and fewer stressful life events. Using a broad definition of a healthy lifestyle, significant predictors were being non-Caucasian, in the lower grade levels at the school, higher academic performance, and fewer stressful life events. In both models, peers' approval of risky behaviors negatively influenced teens' lifestyles, whereas parents' disapproval of risky behaviors was a positive influence. These results reinforce the importance of school, peer, and parent support of positive behaviors. It is important for public health workers and families to understand and define healthy lifestyles choices for adolescents.

Full Text Available Coral growth patterns result from an interplay of coral biology and environmental conditions. In this study colony size and proportion of live and dead skeletons in the cold-water coral (CWC Lophelia pertusa (Linnaeus, 1758 were measured using video footage from Remotely Operated Vehicle (ROV transects conducted at the inshore Mingulay Reef Complex (MRC and at the offshore PISCES site (Rockall Bank in the NE Atlantic. The main goal of this paper was to explore the development of a simple method to quantify coral growth and its potential application as an assessment tool of the health of these remote habitats. Eighteen colonies were selected and whole colony and dead/living layer size were measured. Live to dead layer ratios for each colony were then determined and analysed. The age of each colony was estimated using previously published data. Our paper shows that: (1 two distinct morphotypes can be described: at the MRC, colonies displayed a ‘cauliflower-shaped’ morphotype whereas at the PISCES site, colonies presented a more flattened ‘bush-shaped’ morphotype; (2 living layer size was positively correlated with whole colony size; (3 live to dead layer ratio was negatively correlated to whole colony size; (4 live to dead layer ratio never exceeded 0.27. These results suggest that as a colony develops and its growth rate slows down, the proportion of living polyps in the colony decreases. Furthermore, at least 73% of L. pertusa colonies are composed of exposed dead coral skeleton, vulnerable to ocean acidification and the associated shallowing of the aragonite saturation horizon, with significant implications for future deep-sea reef framework integrity. The clear visual contrast between white/pale living and grey/dark dead portions of the colonies also gives a new way by which they can be visually monitored over time. The increased use of marine autonomous survey vehicles offers an important new platform from which such a surveying

Microbial Surface Colonization and Biofilm Development in Marine Environments

Science.gov (United States)

2015-01-01

SUMMARY Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms. Surface colonization and subsequent biofilm formation and development provide numerous advantages to these organisms and support critical ecological and biogeochemical functions in the changing marine environment. Microbial surface association also contributes to deleterious effects such as biofouling, biocorrosion, and the persistence and transmission of harmful or pathogenic microorganisms and their genetic determinants. The processes and mechanisms of colonization as well as key players among the surface-associated microbiota have been studied for several decades. Accumulating evidence indicates that specific cell-surface, cell-cell, and interpopulation interactions shape the composition, structure, spatiotemporal dynamics, and functions of surface-associated microbial communities. Several key microbial processes and mechanisms, including (i) surface, population, and community sensing and signaling, (ii) intraspecies and interspecies communication and interaction, and (iii) the regulatory balance between cooperation and competition, have been identified as critical for the microbial surface association lifestyle. In this review, recent progress in the study of marine microbial surface colonization and biofilm development is synthesized and discussed. Major gaps in our knowledge remain. We pose questions for targeted investigation of surface-specific community-level microbial features, answers to which would advance our understanding of surface-associated microbial community ecology and the biogeochemical functions of these communities at levels from molecular mechanistic details through systems biological integration.

2012-01-01

The need for alternative sources of energy has never been more urgent than it is today. At the very time International Energy Agency estimates that demand will increase 30% by 2030, fossil fuels (oil, gas and coal) are beginning to dwindle, as the need to counter global warming imposes limits on CO 2 emissions. In this context, DCNS has entered a new field of innovation and development: ocean energy. Having included marine renewable energy as an intrinsic part of its strategic growth plan, DCNS is the only industrial company in the world to invest in all four key technologies in this sector: - the tidal energy generated using underwater turbines known as 'tidal turbines',' which convert the energy of marine tidal streams into electricity; - the ocean thermal energy conversion (OTEC) technology that exploits the difference of temperature between the warm surface water of tropical oceans and the cold water found in the ocean depths to generate electrical power 24 hours a day, 35 days a year; - the offshore wind energy generated by offshore floating wind turbines; - the wave energy technology which operates on the principle of recovering energy from the ocean swell. With 400 years of expertise in shipbuilding and its in-depth understanding of the marine environment, DCNS is committed to playing a major role in the development of this new ocean industry.

Introduction In recent years, many marine resources have drew attention in the research for bio-active compounds to develop new drugs and health foods. (1) Marine algae are now considered as a rich source of antioxidants (2). It is known that seaweeds contain numerous bioactive substances that have the ability to lower cholesterol, reduce blood pressure, promote healthy digestion; and antioxidant activity (3). Natural antioxidants are interesting compounds due to their properties which help prevent oxidative stress (4), among other potentially beneficial actions. For instance, several biological effects have been attributed to flavonoids, such as anti-tumoral, anti-inflammatory, anti-ischemic and anti-aggregate plaquetary activities. These activities are believed to be in part related to the antioxidant properties of the compounds, namely in scavenging radical oxygen species (ROS). (5, 6) The cold ischemia constitute a situation of oxidative stress in touch with liberation of oxygenated radicals, these situations incited the researchers to find means for the improvement of the conservation of organs allowing to prolong the durations of the cold ischemia of certain organs (in particular the liver) with conservation of the maximum functional value. However, the constant efforts led by the teams of transplantation to develop transplants, the conservation of organs remains a problem to be resolved. (7) Conservation solution of organ appears as being a stemming to remedy the fatal effects of the ischemia-reperfusion. For our part, we think that seaweeds have not delivered their secrets and yet especially that the marine environment of the Tunisian coast still remains little exploited in spite of the big variety of the fauna and the flora of the coast. We envisage in this work, to study a sort of seaweed collected on the Tunisian quotation in the region of "Chott Meriem" (North West of Tunisia). The purpose of our work is to estimate the capacity of extracts stemming

Status of marine biodiversity of the China seas.

Directory of Open Access Journals (Sweden)

J Y Liu

Full Text Available China's seas cover nearly 5 million square kilometers extending from the tropical to the temperate climate zones and bordering on 32,000 km of coastline, including islands. Comprehensive systematic study of the marine biodiversity within this region began in the early 1950s with the establishment of the Qingdao Marine Biological Laboratory of the Chinese Academy of Sciences. Since that time scientists have carried out intensive multidisciplinary research on marine life in the China seas and have recorded 22,629 species belonging to 46 phyla. The marine flora and fauna of the China seas are characterized by high biodiversity, including tropical and subtropical elements of the Indo-West Pacific warm-water fauna in the South and East China seas, and temperate elements of North Pacific temperate fauna mainly in the Yellow Sea. The southern South China Sea fauna is characterized by typical tropical elements paralleled with the Philippine-New Guinea-Indonesia Coral triangle typical tropical faunal center. This paper summarizes advances in studies of marine biodiversity in China's seas and discusses current research mainly on characteristics and changes in marine biodiversity, including the monitoring, assessment, and conservation of endangered species and particularly the strengthening of effective management. Studies of (1 a tidal flat in a semi-enclosed embayment, (2 the impact of global climate change on a cold-water ecosystem, (3 coral reefs of Hainan Island and Xisha-Nansha atolls, (4 mangrove forests of the South China Sea, (5 a threatened seagrass field, and (6 an example of stock enhancement practices of the Chinese shrimp fishery are briefly introduced. Besides the overexploitation of living resources (more than 12.4 million tons yielded in 2007, the major threat to the biodiversity of the China seas is environmental deterioration (pollution, coastal construction, particularly in the brackish waters of estuarine environments, which are

On the normative model of a healthy lifestyle

Full Text Available The formation of a healthy lifestyle among the educational process subjects is one of the main functions of health-saving educational space. This function can be implemented effectively only if the executive bodies in the sphere of education, other agencies, the public and the subjects of the educational process take active part in this process. Such cooperation requires a common understanding in the issues to promote health of all pedagogical process participants, but to date the concept “healthy lifestyle” has not been clearly defined and the effective and optimized pedagogical models for its formation, according to the cross-cutting principle, have not been elaborated. The article analyzes different points of view on this issue. A healthy lifestyle is considered as a complex pedagogical technology to create health culture. Taking into account the scholars’ attitudes to the concept “healthy lifestyle” the author identifies three main components of a healthy lifestyle: health culture, health-saving activity and conditions that ensure a healthy lifestyle. The article argues that health saving needs of a person predetermine his/her health-saving activities. It reveals the main strategic sub-components of a healthy lifestyle: physical, environmental, medical, psychological and spiritual-moral activities. The work presents the normative model of a healthy lifestyle and its structure. It defines a healthy lifestyle as a model of health-saving behavior model. The author proves that the proposed normative model of a healthy lifestyle can be successfully used for the formation of health-saving educational space on the principles of inter-sectoral collaboration

The components of lifestyle of medical students, with comprehensive reporting of their physical activity and drinking and eating behavior, are rarely evaluated. Being overweight (increased body mass index - BMI) is associated with health problems, an unhealthy lifestyle (inadequate sleep, diet and exercise) being implicated. The aim was to determine if there were discrepancies between assessments of actual lifestyle and advice regarding the principles of a healthy lifestyle. The relationship between lifestyle and BMI was investigated in 270 medical students (158 females, 112 males) who answered a questionnaire about aspects of their lifestyle. The mean ±SD BMI in males (23.41 ±0.25kg/m2) was significantly higher than in females (20.52 ±0.16kg/m2). Many aspects of lifestyle differed significantly with gender, including sleep habits, number of meals eaten, types of food eaten (fast food, amounts of fresh fruit and vegetables, sweets, etc.) and alcohol consumption, males generally having less healthy lifestyles. After correcting the associations between BMI and lifestyle factors for gender, one main finding was a positive association between BMI and alcohol intake, BMI rising by 0.014 kg/m2/g alcohol intake per week. These results show clear differences between actual and advised lifestyle with regard to many aspects of sleep, food and fluid intake, and exercise. Most students, particularly males, had not adopted a healthy lifestyle. Possible future problems associated with this require more emphasis.

The bean bug (Riptortus pedestris) is a pest of soybeans and other legumes in Japan and other Asian countries. It enters a facultative adult diapause on exposure to short days. While photoperiodism and diapause are well understood in R. pedestris, knowledge of cold tolerance is very limited, as is information on the effect of diapause on cold tolerance. We examined the effect of photoperiod, cold acclimation, and feeding status on cold tolerance in R. pedestris. We found that cold acclimation significantly increased survival at -10°C in both long- and short-day adult R. pedestris. Since the difference in cold survival between long- and short-day cold-acclimated groups was only marginal, we conclude that entering diapause is not crucial for R. pedestris to successfully pass through cold acclimation and become cold tolerant. We observed similar effects in 5th instar nymphs, with both long- and short-day cold-acclimated groups surviving longer cold exposures compared with non-acclimated groups. Starvation, which was tested only in adult bugs, had only a negligible and negative impact on cold survival. Although cold tolerance significantly increased with cold acclimation in adult bugs, supercooling capacity unexpectedly decreased. Our results suggest that changes in supercooling capacity as well as in water content are unrelated to cold tolerance in R. pedestris. An analysis of metabolites revealed differences between the treatments, and while several metabolites markedly increased with cold acclimation, their concentrations were too low to have a significant effect on cold tolerance.

Convergent evolution of marine mammals is associated with distinct substitutions in common genes

2015-01-01

Phenotypic convergence is thought to be driven by parallel substitutions coupled with natural selection at the sequence level. Multiple independent evolutionary transitions of mammals to an aquatic environment offer an opportunity to test this thesis. Here, whole genome alignment of coding sequences identified widespread parallel amino acid substitutions in marine mammals; however, the majority of these changes were not unique to these animals. Conversely, we report that candidate aquatic adaptation genes, identified by signatures of likelihood convergence and/or elevated ratio of nonsynonymous to synonymous nucleotide substitution rate, are characterized by very few parallel substitutions and exhibit distinct sequence changes in each group. Moreover, no significant positive correlation was found between likelihood convergence and positive selection in all three marine lineages. These results suggest that convergence in protein coding genes associated with aquatic lifestyle is mainly characterized by independent substitutions and relaxed negative selection. PMID:26549748

The relations between salivary variables, lifestyle and mental health status were investigated for 61 healthy female university students. The salivary secretion rates were significantly higher in the good lifestyle groups compared with the poor lifestyle groups. Among the 8 lifestyle items tested. "eating breakfast" and "mental stress" were significantly related to the salivary secretion rates. The present findings suggest that the acquisition of a good lifestyle is also very important from the viewpoint of the prevention of oral disease.A highly significant correlation (r=0.97; p<0.01) between the salivary cortisol levels and the cortisol secretion rates when controlled for the salivary secretion rates was also observed. This suggests that there is a high correlation between the intact salivary cortisol levels and the total cortisol quantity per unit time. Therefore, both these values can be used as a good index for the salivary cortisol determination.

Gut Microbiota and Lifestyle Interventions in NAFLD

2016-01-01

The human digestive system harbors a diverse and complex community of microorganisms that work in a symbiotic fashion with the host, contributing to metabolism, immune response and intestinal architecture. However, disruption of a stable and diverse community, termed “dysbiosis”, has been shown to have a profound impact upon health and disease. Emerging data demonstrate dysbiosis of the gut microbiota to be linked with non-alcoholic fatty liver disease (NAFLD). Although the exact mechanism(s) remain unknown, inflammation, damage to the intestinal membrane, and translocation of bacteria have all been suggested. Lifestyle intervention is undoubtedly effective at improving NAFLD, however, not all patients respond to these in the same manner. Furthermore, studies investigating the effects of lifestyle interventions on the gut microbiota in NAFLD patients are lacking. A deeper understanding of how different aspects of lifestyle (diet/nutrition/exercise) affect the host–microbiome interaction may allow for a more tailored approach to lifestyle intervention. With gut microbiota representing a key element of personalized medicine and nutrition, we review the effects of lifestyle interventions (diet and physical activity/exercise) on gut microbiota and how this impacts upon NAFLD prognosis.

Highlights: • T-Hg, MMHg, and Hg isotopes were determined in Gulf of Mexico deep marine sediments. • Levels of mass independent fractionation of Hg isotopes varied from coastal sediments. • Levels of the MMHg were only slightly elevated at the cold seep site. • Cold seeps do not appear to be significant sources of MMHg to Gulf of Mexico waters. -- Abstract: Total-Hg, monomethylmercury (MMHg), and mercury isotopic composition was determined in sediment from a cold seep and background sites in the northern Gulf of Mexico (nGoM). Total-Hg averaged 50 ng/g (n = 28), ranged from 31 to 67 ng/g, and decreased with depth (0–15 cm). MMHg averaged 0.91 ng/g (n = 18), and ranged from 0.2 to 1.9 ng/g. There was no significant difference for total-Hg or MMHg between cold seep and background sites. δ 202 Hg ranged from −0.5 to −0.8‰ and becomes more negative with depth (r = 0.989). Mass independent fractionation (Δ 199 Hg) was small but consistently positive (0.04–0.12‰); there was no difference between cold seeps (Δ 199 Hg = +0.09 ± 0.03; n = 7, 1SD) and background sites (Δ 199 Hg = +0.07 ± 0.02; n = 5, 1SD). This suggests that releases of hydrocarbons at the cold seep do not significantly alter Hg levels, and that cold seeps are likely not major sources of MMHg to nGoM waters

Stroke is a major cause of disability and family disruption and carries a high risk of recurrence. Lifestyle factors that increase the risk of recurrence include smoking, unhealthy diet, excessive alcohol consumption and physical inactivity. Guidelines recommend that secondary prevention interventions, which include the active provision of lifestyle information, should be initiated in hospital, and continued by community-based healthcare professionals (HCPs) following discharge. However, stroke patients report receiving little/no lifestyle information.There is a limited evidence-base to guide the development and delivery of effective secondary prevention lifestyle interventions in the stroke field. This study, which was underpinned by the Theory of Planned Behaviour, sought to explore the beliefs and perceptions of patients and family members regarding the provision of lifestyle information following stroke. We also explored the influence of beliefs and attitudes on behaviour. We believe that an understanding of these issues is required to inform the content and delivery of effective secondary prevention lifestyle interventions. We used purposive sampling to recruit participants through voluntary sector organizations (29 patients, including 7 with aphasia; 20 family members). Using focus group methods, data were collected in four regions of Scotland (8 group discussions) and were analysed thematically. Although many participants initially reported receiving no lifestyle information, further exploration revealed that most had received written information. However, it was often provided when people were not receptive, there was no verbal reinforcement, and family members were rarely involved, even when the patient had aphasia. Participants believed that information and advice regarding healthy lifestyle behaviour was often confusing and contradictory and that this influenced their behavioural intentions. Family members and peers exerted both positive and negative

To examine (1) the prevalence of four lifestyle behaviours among Australia Post employees and (2) employees' perceptions of the role of the workplace in promotion of lifestyle change. A cross-sectional survey using a self-administered questionnaire involved 688 employees working in Australia Post throughout metropolitan Sydney. Prevalence related to age and sex of alcohol consumption, cigarette smoking, inadequate exercise, perception of excessive weight. 36% of men and 11% of women reported drinking alcohol at levels considered hazardous or harmful; 33% of men and 25% of women reported smoking; 51% of men and 62% of women thought they were overweight; 30% of men and 39% of women did not exercise regularly. Younger respondents were more likely to report drinking hazardously or harmfully, were smokers and had multiple risk factors. A majority of respondents thought that their employer should be interested in employee's lifestyle issues, particularly excessive drinking (63%). However, few considered seeking advice from the workplace regarding smoking (16%), weight (25%) and excessive alcohol consumption (12%). These results show that many of Australia Post employees have unhealthy lifestyle behaviours. While employees perceive that the workplace has an important role in promoting healthy lifestyles among staff, few are presently willing to seek advice from the workplace regarding these issues. Promotion of healthy lifestyles in Australian workplaces is a potentially important public health advance that could reduce the incidence of diseases associated with high-risk lifestyle behaviours.

Daanen, Hein A M; Van Marken Lichtenbelt, Wouter D

2016-01-01

Reviews on whole body human cold adaptation generally do not distinguish between population studies and dedicated acclimation studies, leading to confusing results. Population studies show that indigenous black Africans have reduced shivering thermogenesis in the cold and poor cold induced vasodilation in fingers and toes compared to Caucasians and Inuit. About 40,000 y after humans left Africa, natives in cold terrestrial areas seems to have developed not only behavioral adaptations, but also physiological adaptations to cold. Dedicated studies show that repeated whole body exposure of individual volunteers, mainly Caucasians, to severe cold results in reduced cold sensation but no major physiological changes. Repeated cold water immersion seems to slightly reduce metabolic heat production, while repeated exposure to milder cold conditions shows some increase in metabolic heat production, in particular non-shivering thermogenesis. In conclusion, human cold adaptation in the form of increased metabolism and insulation seems to have occurred during recent evolution in populations, but cannot be developed during a lifetime in cold conditions as encountered in temperate and arctic regions. Therefore, we mainly depend on our behavioral skills to live in and survive the cold.

In China, the health impact of cold weather has received little attention, which limits our understanding of the health impacts of climate change. We collected daily mortality and meteorological data in 66 communities across China from 2006 to 2011. Within each community, we estimated the effect of cold spell exposure on mortality using a Distributed Lag Nonlinear Model (DLNM). We also examined the modification effect of cold spell characteristics (intensity, duration, and timing) and individual-specific factors (causes of death, age, gender and education). Meta-analysis method was finally used to estimate the overall effects. The overall cumulative excess risk (CER) of non-accidental mortality during cold spell days was 28.2% (95% CI: 21.4%, 35.3%) compared with non-cold spell days. There was a significant increase in mortality when the cold spell duration and intensity increased or occurred earlier in the season. Cold spell effects and effect modification by cold spell characteristics were more pronounced in south China. The elderly, people with low education level and those with respiratory diseases were generally more vulnerable to cold spells. Cold spells statistically significantly increase mortality risk in China, with greater effects in southern China. This effect is modified by cold spell characteristics and individual-level factors.

Psychosocial stress has been linked with an unhealthy lifestyle but the relation's direction remains unclear. Does stress induce sleeping problems, comfort food consumption, and lower physical activity, or do these unhealthy lifestyle factors enhance stress? This study examined the bidirectional stress-lifestyle relation in children. The relation between stress and lifestyle was examined over 2 years in 312 Belgian children 5-12 years old as part of the Children's Body Composition and Stress study. Stress-related aspects were measured by questionnaires concerning negative events, negative emotions, and behavioral problems. The following lifestyle factors were assessed: physical activity (by accelerometers), sleep duration, food consumption (sweet food, fatty food, snacks, fruits and vegetables), and eating behavior (emotional, external, restrained). Bidirectional relations were examined with cross-lagged analyses. Certain stress aspects increased physical activity, sweet food consumption, emotional eating, restrained eating, and external eating (βs = .140-.319). All relations were moderated by sex and age: Dietary effects were mainly in the oldest children and girls; stress increased physical activity in the youngest, whereas it tended to decrease physical activity in the oldest. One reversed direction effect was found: Maladaptive eating behaviors increased anxiety feelings. Relations were mainly unidirectional: Stress influenced children's lifestyle. Stress stimulated eating in the absence of hunger, which could facilitate overweight. Consequently, families should realize that stress may influence children's diet, and problem-solving coping skills should be acquired. In contrast to recent findings, stress might also stimulate physical activity in the youngest as positive stress coping style.

Health lifestyle theory and the convergence of agency and structure.

Science.gov (United States)

Cockerham, William C

2005-03-01

This article utilizes the agency-structure debate as a framework for constructing a health lifestyle theory. No such theory currently exists, yet the need for one is underscored by the fact that many daily lifestyle practices involve considerations of health outcomes. An individualist paradigm has influenced concepts of health lifestyles in several disciplines, but this approach neglects the structural dimensions of such lifestyles and has limited applicability to the empirical world. The direction of this article is to present a theory of health lifestyles that includes considerations of both agency and structure, with an emphasis upon restoring structure to its appropriate position. The article begins by defining agency and structure, followed by presentation of a health lifestyle model and the theoretical and empirical studies that support it.

Amino sugars are quantitatively significant constituents of soil and marine sediment, but their sources and turnover in environmental samples remain poorly understood. The stable carbon isotopic composition of amino sugars can provide information on the lifestyles of their source organisms and can be monitored during incubations with labeled substrates to estimate the turnover rates of microbial populations. However, until now, such investigation has been carried out only with soil samples, partly because of the much lower abundance of amino sugars in marine environments. We therefore optimized a procedure for compound-specific isotopic analysis of amino sugars in marine sediment, employing gas chromatography-isotope ratio mass spectrometry. The whole procedure consisted of hydrolysis, neutralization, enrichment, and derivatization of amino sugars. Except for the derivatization step, the protocol introduced negligible isotopic fractionation, and the minimum requirement of amino sugar for isotopic analysis was 20 ng, i.e., equivalent to ~8 ng of amino sugar carbon. Compound-specific stable carbon isotopic analysis of amino sugars obtained from marine sediment extracts indicated that glucosamine and galactosamine were mainly derived from organic detritus, whereas muramic acid showed isotopic imprints from indigenous bacterial activities. The δ13C analysis of amino sugars provides a valuable addition to the biomarker-based characterization of microbial metabolism in the deep marine biosphere, which so far has been lipid oriented and biased towards the detection of archaeal signals.

Cognitive reserve and lifestyle: moving towards preclinical Alzheimer’s disease

Directory of Open Access Journals (Sweden)

Eider M Arenaza-Urquijo

2015-08-01

Full Text Available The large majority of neuroimaging studies in Alzheimer’s disease (AD patients have supported the idea that lifestyle factors may protect against the clinical manifestations of AD rather than influence AD neuropathological processes (the cognitive reserve hypothesis. This evidence argues in favor of the hypothesis that lifestyle factors act as moderators between AD pathology and cognition, i.e. through indirect compensatory mechanisms. In this review, we identify emerging evidence in cognitively normal older people that relate lifestyle factors to established AD neuroimaging biomarkers. While some of these investigations are in agreement with the compensatory view of cognitive reserve, other studies have revealed new clues on the neural mechanisms underlying beneficial effects of lifestyle factors on the brain. Specifically, they provide novel evidence suggesting direct effects of lifestyle factors on AD neuropathological processes. Here, we review current findings on the effects of lifestyle factors on AD neuroimaging biomarkers in cognitively normal older people. We propose a tentative theoretical model where lifestyle factors may act via direct neuroprotective and/or indirect compensatory pathways. Importantly, we suggest that neuroprotective mechanisms may have a major role during early stages and compensatory pathways in later stages of the disease. In the absence of an effective treatment for AD and considering the potential of lifestyle factors in AD prevention, understanding the neural mechanisms underlying lifestyle effects on the brain seems crucial. We hope to provide an integrative view that may help to better understand the complex effects of lifestyle factors on AD neuropathological processes, starting from the preclinical stage.

2010-06-01

Full Text Available Chronic diseases continue to be a significant burden to the health care system. Pharmacists have been able to show that drug therapy for patients with chronic diseases can be improved through medication therapy management (MTM services but have yet to become significantly involved in implementing lifestyle modification programs to further control and prevent chronic conditions. A novel and innovative lifestyle medicine program was started by pharmacists in a community pharmacy in 2008 to more comprehensively prevent and manage chronic conditions. The lifestyle medicine program consists of designing seven personalized programs for patients to address physical activity, nutrition, alcohol consumption, weight control, stress management, sleep success, and tobacco cessation (if needed. The lifestyle medicine program complements existing MTM services for patients with hypertension, dyslipidemia, and/or diabetes. This program is innovative because pharmacists have developed and implemented a method to combine lifestyle medicine with MTM services to not only manage chronic conditions, but prevent the progression of those conditions and others. Several innovative tools have also been developed to enhance the effectiveness of a lifestyle medicine program. This manuscript describes the program's pharmacy setting, pharmacy personnel, participants and program details as well as the tools used to integrate a lifestyle medicine program with MTM services.

Testes of most male mammals present the particularity of being externalized from the body and are consequently slightly cooler than core body temperature (4-8°C below). Although, hypothermia of the testis is known to increase germ cells apoptosis, little is known about the underlying molecular mechanisms, including cold sensors, transduction pathways, and apoptosis triggers. In this study, using a functional knockout mouse model of the cold and menthol receptors, dubbed transient receptor potential melastatine 8 (TRPM8) channels, we found that TRPM8 initiated the cold-shock response by differentially modulating cold- and heat-shock proteins. Besides, apoptosis of germ cells increased in proportion to the cooling level in control mice but was independent of temperature in knockout mice. We also observed that the rate of germ cell death correlated positively with the reactive oxygen species level and negatively with the expression of the detoxifying enzymes. This result suggests that the TRPM8 sensor is a key determinant of germ cell fate under hypothermic stimulation.-Borowiec, A.-S., Sion, B., Chalmel, F., Rolland, A.

Lipids of Prokaryotic Origin at the Base of Marine Food Webs

Directory of Open Access Journals (Sweden)

Maria José Caramujo

2012-11-01

Full Text Available In particular niches of the marine environment, such as abyssal trenches, icy waters and hot vents, the base of the food web is composed of bacteria and archaea that have developed strategies to survive and thrive under the most extreme conditions. Some of these organisms are considered “extremophiles” and modulate the fatty acid composition of their phospholipids to maintain the adequate fluidity of the cellular membrane under cold/hot temperatures, elevated pressure, high/low salinity and pH. Bacterial cells are even able to produce polyunsaturated fatty acids, contrarily to what was considered until the 1990s, helping the regulation of the membrane fluidity triggered by temperature and pressure and providing protection from oxidative stress. In marine ecosystems, bacteria may either act as a sink of carbon, contribute to nutrient recycling to photo-autotrophs or bacterial organic matter may be transferred to other trophic links in aquatic food webs. The present work aims to provide a comprehensive review on lipid production in bacteria and archaea and to discuss how their lipids, of both heterotrophic and chemoautotrophic origin, contribute to marine food webs.

Metagenomics uncovers a new group of low GC and ultra-small marine Actinobacteria

Science.gov (United States)

Ghai, Rohit; Mizuno, Carolina Megumi; Picazo, Antonio; Camacho, Antonio; Rodriguez-Valera, Francisco

2013-01-01

We describe a deep-branching lineage of marine Actinobacteria with very low GC content (33%) and the smallest free living cells described yet (cell volume ca. 0.013 μm3), even smaller than the cosmopolitan marine photoheterotroph, ‘Candidatus Pelagibacter ubique'. These microbes are highly related to 16S rRNA sequences retrieved by PCR from the Pacific and Atlantic oceans 20 years ago. Metagenomic fosmids allowed a virtual genome reconstruction that also indicated very small genomes below 1 Mb. A new kind of rhodopsin was detected indicating a photoheterotrophic lifestyle. They are estimated to be ~4% of the total numbers of cells found at the site studied (the Mediterranean deep chlorophyll maximum) and similar numbers were estimated in all tropical and temperate photic zone metagenomes available. Their geographic distribution mirrors that of picocyanobacteria and there appears to be an association between these microbial groups. A new sub-class, ‘Candidatus Actinomarinidae' is proposed to designate these microbes. PMID:23959135

Cold stress alters transcription in meiotic anthers of cold tolerant chickpea (Cicer arietinum L.).

Science.gov (United States)

Sharma, Kamal Dev; Nayyar, Harsh

2014-10-11

Cold stress at reproductive phase in susceptible chickpea (Cicer arietinum L.) leads to pollen sterility induced flower abortion. The tolerant genotypes, on the other hand, produce viable pollen and set seed under cold stress. Genomic information on pollen development in cold-tolerant chickpea under cold stress is currently unavailable. DDRT-PCR analysis was carried out to identify anther genes involved in cold tolerance in chickpea genotype ICC16349 (cold-tolerant). A total of 9205 EST bands were analyzed. Cold stress altered expression of 127 ESTs (90 up-regulated, 37 down-regulated) in anthers, more than two third (92) of which were novel with unknown protein identity and function. Remaining about one third (35) belonged to several functional categories such as pollen development, signal transduction, ion transport, transcription, carbohydrate metabolism, translation, energy and cell division. The categories with more number of transcripts were carbohydrate/triacylglycerol metabolism, signal transduction, pollen development and transport. All but two transcripts in these categories were up-regulated under cold stress. To identify time of regulation after stress and organ specificity, expression levels of 25 differentially regulated transcripts were also studied in anthers at six time points and in four organs (anthers, gynoecium, leaves and roots) at four time points. Limited number of genes were involved in regulating cold tolerance in chickpea anthers. Moreover, the cold tolerance was manifested by up-regulation of majority of the differentially expressed transcripts. The anthers appeared to employ dual cold tolerance mechanism based on their protection from cold by enhancing triacylglycerol and carbohydrate metabolism; and maintenance of normal pollen development by regulating pollen development genes. Functional characterization of about two third of the novel genes is needed to have precise understanding of the cold tolerance mechanisms in chickpea anthers.

Housing-related lifestyle and energy saving: A multi-level approach

International Nuclear Information System (INIS)

Thøgersen, John

2017-01-01

A new instrument for measuring housing-related lifestyle (HRL) is introduced and employed for identifying national and cross-national HRL segments in 10 European countries (N=3190). The identified HRL segments are profiled and the practical importance of HRL for everyday energy-saving efforts in the home and for the energy-consumer's openness to new energy saving opportunities (i.e., energy saving innovativeness) is investigated. The HRL instrument's 71 items load on 16 dimensions within five lifestyle elements. Multi-group confirmatory factor analysis reveals that the instrument possesses metric but not scalar (measurement) invariance across the 10 countries. Multilevel latent class analysis is used to classify participants to HRL segments and the 10 countries into regions with similar segment structure. The optimal solution has seven HRL segments and three country classes, which are profiled in terms of relevant background characteristics. A multivariate GLM analysis reveals that when differences in housing-related lifestyles are controlled, neither country of residence nor the interaction between lifestyle and country of residence influence energy saving innovativeness or everyday energy-saving efforts. However, these two behavioural tendencies vary significantly and substantially between lifestyle segments. The study shows that HRL segmentation is a useful tool for creating more targeted and effective energy-saving campaigns. - Highlights: • 7 housing-related lifestyle segments identified in 10 European countries. • The 10 countries cluster in 3 regions with similar housing-related lifestyle pattern. • Lifestyle segments differ significantly with regard to energy saving efforts. • Lifestyle segments also differ with regard to energy saving innovativeness. • Housing-related lifestyle mediate all effects of country on energy saving.

Structural Components of Lifestyle and Beyond: The Case of Hungary

Directory of Open Access Journals (Sweden)

Tamás Keller

2011-06-01

Full Text Available This paper deals with the question of when and how lifestyle and its components are important in social stratification. There is considerable consensus among scholars about the structure of the society being a consequence of hierarchical dimensions like occupation, income, or wealth. Some thirty years ago, largely based on Bourdieu’s “Distinction”, a new paradigm emerged highlighting the lifestyle components and the value-oriented cultural and material consumption in stratifi cation. The idea refl ects the empirical fi nding that inequality between social classes has largely decreased, giving priority to horizontal lifestyle differentiation instead of vertical inequality dimensions. From a theoretical viewpoint, a challenge in the approach is finding out to what extent lifestyle typology is of a non-vertical character in reality. This social determination of lifestyle is investigated for Hungary when comparing an occupation-based typology with a consumption-based one. On the one hand, results reveal that the effects of structural components on social status are stronger than those of lifestyle. On the other hand, lifestyle turns out to be less independent of social position and the top and bottom levels of the lifestyle typology are particularly predictable by structural measures.

Lifestyle factors and reproductive health: taking control of your fertility.

Sharma, Rakesh; Biedenharn, Kelly R; Fedor, Jennifer M; Agarwal, Ashok

2013-07-16

Approximately 10 to 15% of couples are impacted by infertility. Recently, the pivotal role that lifestyle factors play in the development of infertility has generated a considerable amount of interest. Lifestyle factors are the modifiable habits and ways of life that can greatly influence overall health and well-being, including fertility. Many lifestyle factors such as the age at which to start a family, nutrition, weight, exercise, psychological stress, environmental and occupational exposures, and others can have substantial effects on fertility; lifestyle factors such as cigarette smoking, illicit drug use, and alcohol and caffeine consumption can negatively influence fertility while others such as preventative care may be beneficial. The present literature review encompasses multiple lifestyle factors and places infertility in context for the couple by focusing on both males and females; it aims to identify the roles that lifestyle factors play in determining reproductive status. The growing interest and amount of research in this field have made it evident that lifestyle factors have a significant impact on fertility.

Lifestyle and precision diabetes medicine: will genomics help optimise the prediction, prevention and treatment of type 2 diabetes through lifestyle therapy?

Science.gov (United States)

Franks, Paul W; Poveda, Alaitz

2017-05-01

Precision diabetes medicine, the optimisation of therapy using patient-level biomarker data, has stimulated enormous interest throughout society as it provides hope of more effective, less costly and safer ways of preventing, treating, and perhaps even curing the disease. While precision diabetes medicine is often framed in the context of pharmacotherapy, using biomarkers to personalise lifestyle recommendations, intended to lower type 2 diabetes risk or to slow progression, is also conceivable. There are at least four ways in which this might work: (1) by helping to predict a person's susceptibility to adverse lifestyle exposures; (2) by facilitating the stratification of type 2 diabetes into subclasses, some of which may be prevented or treated optimally with specific lifestyle interventions; (3) by aiding the discovery of prognostic biomarkers that help guide timing and intensity of lifestyle interventions; (4) by predicting treatment response. In this review we overview the rationale for precision diabetes medicine, specifically as it relates to lifestyle; we also scrutinise existing evidence, discuss the barriers germane to research in this field and consider how this work is likely to proceed.

[Ancient dietetics - lifestyle and medicine].

Science.gov (United States)

Steger, Florian

2004-01-01

The wide reaching meaning of eating and drinking is already recognized in antiquity. The declared aim of antique dietetics is the upbringing to a healthy lifestyle. Fundamental considerations of dietetic, theoretically organized ideas can be traced back to the Presocratics, who, for the first time in cultural history, let themselves be guided by direct observations from nature. Working from the meaning of dietetics as pure nutritional teaching, one can see in the Corpus Hippocraticum a significant, systematic attempt to put forth dietetics as a concept of lifestyle. Here a central aspect is that of equilibrium, as it is expressed in the rule of the four humours. Dietetics continually become a connecting link between Natural Philosophy and Anthropology and a lifestyle orientated to nature. Finally, Galen introduces a further systematization of the already existing and the increasingly modified. Nutrition and health are brought into association and the theoretical presupposed practically overturned. In late Antiquity dietetical outlooks continue to be discussed, which were transferred to the Middle Ages and still show practical relevance.

Full Text Available Adake Saiken, Fang Gu Department of Gastroenterology, Peking University Third Hospital, Beijing, People’s Republic of China Objective: The purpose of this study was to determine the lifestyle and lifestyle-related comorbidities independently associated with colorectal adenoma (CRA recurrence in elderly Chinese people. Methods: During the 5-year follow-up after the initial colonoscopy, participants aged >60 years with the diagnosis and removal of CRA underwent a complete surveillance colonoscopy, and 152 participants with CRA recurrence plus 152 participants free of recurrence were included in this analysis. Results: Participants with CRA recurrence were more likely to consume less vegetables and fruits, and more red meats compared with the control group (P<0.05 for all. Lifestyle-related comorbidities, including hypertension and nonalcoholic fatty liver disease (NAFLD, were more common in participants with CRA recurrence than in the control group (P<0.05 for all. In the multivariate analysis, pack-years of smoking were independently associated with an increased CRA recurrence (odds ratio [OR]: 1.03; P<0.05. Eating less vegetables (OR: 099; P<0.05 and fruits (OR: 0.98; P<0.05 was identified as a statistically independent factor influencing CRA recurrence, as was eating more red meats (OR: 1.01; P<0.05. Hypertension was also found to be a factor independently associated with an increased CRA recurrence (OR: 2.44; P<0.05. NAFLD had an independent association, with an increased CRA recurrence (OR: 3.43; P<0.05. Conclusion: Smoking cigarettes, high consumption of red meats, low intake of fruits and vegetables, and the presence of hypertension and NAFLD were independently associated with an increased CRA recurrence in elderly Chinese people. This conclusion helps elderly Chinese people to make effective behavioral changes, such as smoking cessation, substitution of fruits and vegetables for red meats, and timely treatment of hypertension and NAFLD

Viable cold-tolerant iron-reducing microorganisms in geographically diverse subglacial environments

Science.gov (United States)

Nixon, Sophie L.; Telling, Jon P.; Wadham, Jemma L.; Cockell, Charles S.

2017-03-01

Subglacial environments are known to harbour metabolically diverse microbial communities. These microbial communities drive chemical weathering of underlying bedrock and influence the geochemistry of glacial meltwater. Despite its importance in weathering reactions, the microbial cycling of iron in subglacial environments, in particular the role of microbial iron reduction, is poorly understood. In this study we address the prevalence of viable iron-reducing microorganisms in subglacial sediments from five geographically isolated glaciers. Iron-reducing enrichment cultures were established with sediment from beneath Engabreen (Norway), Finsterwalderbreen (Svalbard), Leverett and Russell glaciers (Greenland), and Lower Wright Glacier (Antarctica). Rates of iron reduction were higher at 4 °C compared with 15 °C in all but one duplicated second-generation enrichment culture, indicative of cold-tolerant and perhaps cold-adapted iron reducers. Analysis of bacterial 16S rRNA genes indicates Desulfosporosinus were the dominant iron-reducing microorganisms in low-temperature Engabreen, Finsterwalderbreen and Lower Wright Glacier enrichments, and Geobacter dominated in Russell and Leverett enrichments. Results from this study suggest microbial iron reduction is widespread in subglacial environments and may have important implications for global biogeochemical iron cycling and export to marine ecosystems.

Sleep disorder is associated with the lifestyle-related diseases including obesity, insulin resistance and atherosclerosis. Adipose tissue functions as an endocrine organ by producing bioactive secretory proteins, also known as adipokines, that can directly act on nearby or remote organs. Recently, the associations between these adipokines and sleep disorders such as obstructive sleep apnea have been reported. In this review, we focus on the relationship between sleep disorder and lifestyle-related diseases.

Inequality in health versus inequality in lifestyle choices

Directory of Open Access Journals (Sweden)

Arnstein Øvrum

2015-10-01

Full Text Available Repeated Norwegian cross-sectional data for the period 2005 to 2011 are used to compare sources of inequality in health, as represented by self-assessed health and obesity, with sources of inequality in lifestyles that are central to the production of health, as represented by physical activity, cigarette smoking and dietary behavior. Sources of overall inequality and socioeconomic inequality in these lifestyle and health indicators are compared by estimating probit models, and by decomposing the explained part of the associated Gini and concentration indices with respect to education and income. As potential sources of inequality, we consider education, income, occupation, age, gender, marital status, psychological traits and childhood circumstances. Our results suggest that sources of inequality in health are not necessarily representative of sources of inequality in underlying lifestyles. While education is generally an important source of overall inequality in both lifestyles and health, income is unimportant in all lifestyle indicators except physical activity. In several cases, education and income are clearly outranked by other factors in terms of explaining overall inequality, such as gender in eating fruits and vegetables and age in fish consumption. These results suggest that it is important to decompose both overall inequality and socioeconomic inequality in different lifestyle and health indicators. In indicators where other factors than education and income are clearly most important, policy makers should consider to target these factors to efficiently improve overall population health.

Walking and biking to school can be an important part of a healthy lifestyle, yet most US children do not start their day with these activities. The Safe Routes to School Program in Marin County, California, is working to promote walking and biking to school. Using a multipronged approach, the program identifies and creates safe routes to schools and invites communitywide involvement. By its second year, the program was serving 4665 students in 15 schools. Participating public schools reported an increase in school trips made by walking (64%), biking (114%), and carpooling (91%) and a decrease in trips by private vehicles carrying only one student (39%).

Full Text Available This article aims at finding different lifestyles of female clothing in Tehran. To this end, it describes women’s diverse types of clothing in different social and cultural environments. The main questions advanced in the article are about special lifestyles and logic of choosing clothes by women. The authors try to discover whether distinction, identity making or some kinds of primary functions such as protection, decoration, and chastity are considered the most important factors for women. To find answers, the authors conducted deep interviews with 40 female residents of Tehran and extracted their social positions and lifestyle in clothing. Based on these findings, the authors could distinguish nine different social types.

This is the first study describing the tobacco industry's objectives developing and publishing lifestyle magazines, linking them to tobacco marketing strategies, and how these magazines may encourage smoking. Analysis of previously secret tobacco industry documents and content analysis of 31 lifestyle magazines to understand the motives behind producing these magazines and the role they played in tobacco marketing strategies. Philip Morris (PM) debuted Unlimited in 1996 to nearly 2 million readers and RJ Reynolds (RJR) debuted CML in 1999, targeting young adults with their interests. Both magazines were developed as the tobacco companies faced increased advertising restrictions. Unlimited contained few images of smoking, but frequently featured elements of the Marlboro brand identity in both advertising and article content. CML featured more smoking imagery and fewer Camel brand identity elements. Lifestyle promotions that lack images of smoking may still promote tobacco use through brand imagery. The tobacco industry still uses the "under-the-radar" strategies used in development of lifestyle magazines in branded Websites. Prohibiting lifestyle advertising including print and electronic media that associate tobacco with recreation, action, pleasures, and risky behaviors or that reinforces tobacco brand identity may be an effective strategy to curb young adult smoking.

This article brings together the fields of Cold War studies and memory studies. In Denmark, a remarkable institutionalisation of Cold War memory has taken place in the midst of a heated ideological battle over the past and whether to remember the Cold War as a ‘war’. Using Danish Cold War museums...... and heritage sites as case studies, this article sheds new light on the politics of history involved in Cold War commemoration. It suggests that the Cold War is commemorated as a war, yet this war memory is of a particular kind: it is a war memory without victims....

A variety of ecologically important processes are driven by bacterial motility and taxis, yet these basic bacterial behaviours remain understudied in cold habitats. Here, we present a series of experiments designed to test the chemotactic ability of the model marine psychrophilic bacterium Colwellia psychrerythraea 34H, when grown at optimal temperature and salinity (8°C, 35 ppt) or its original isolation conditions (-1°C, 35 ppt), towards serine and mannose at temperatures from -8°C to 27°C (above its upper growth temperature of 18°C), and at salinities of 15, 35 and 55 ppt (at 8°C and -1°C). Results indicate that C. psychrerythraea 34H is capable of chemotaxis at all temperatures tested, with strongest chemotaxis at the temperature at which it was first grown, whether 8°C or -1°C. This model marine psychrophile also showed significant halotaxis towards 15 and 55 ppt solutions, as well as strong substrate-specific chemohalotaxis. We suggest that such patterns of taxis may enable bacteria to colonize sea ice, position themselves optimally within its extremely cold, hypersaline and temporally fluctuating microenvironments, and respond to various chemical signals therein. © 2017 The Authors.

The use of scalp cooling for the prevention of chemotherapy-induced alopecia (CIA) is increasing. Cold caps are placed onto the hair-bearing areas of the scalp for varying time periods before, during, and after cytotoxic chemotherapy. Although not yet reported, improper application procedures could result in adverse events (AEs). At present, there are no evidence-based scalp cooling protocols, and there is no regulatory oversight of their use. To report the occurrence of cold thermal injury (frostbite) on the scalp, following the use of cold caps for the prevention of CIA. We identified four patients who developed cold thermal injuries on the scalp following the application of cold caps. Medical records were analyzed to retrieve the demographic and clinical characteristics. The cold thermal injuries in our patients were grade 1/2 in severity and improved with topical interventions and interruption of cold cap use, although grade 1 persistent alopecia ensued in 3 patients. The true incidence of such injuries in this setting, however, remains unknown. Cold thermal injuries are likely infrequent and preventable AEs that may result from improper device application procedures during cold cap use. Although these untoward events are usually mild to moderate in severity, the potential occurrence of long-term sequelae (e.g., permanent alopecia and scarring) or the need to discontinue cold cap use, are not known. Prospective studies are needed to further elucidate the risk and standardize healthcare delivery methods, and to improve patient/supportive/healthcare provider education.

Previous knowledge of the impact of certain life-style factors on hand eczema is scanty. To investigate a possible association between hand eczema and life-style factors such as obesity, physical exercise, stress, smoking and alcohol consumption. In a cross-sectional public health survey in Stockholm, Sweden, 27,994 (58%) randomly chosen individuals aged 18-64 years completed a postal questionnaire regarding physical and mental health, social relations, economic status and work. Of these, 27,793 individuals responded to the question regarding hand eczema and were included in the present study. The association between life-style factors and hand eczema was analysed by prevalence proportion ratios (PPR), using a generalized linear model. Hand eczema was more common among individuals who reported high stress levels, PPR 1·326 (95% CI 1·303-1·350). There was also a positive dose-response relationship between hand eczema and stress. Hand eczema was less common among individuals reporting high physical exercise, and most apparent in women, PPR 0·781 (95% CI 0·770-0·792). Men who reported high alcohol intake reported hand eczema less often, PPR 0·958 (95% CI 0·930-0·987). Obese individuals reported hand eczema more commonly, PPR 1·204 (95% CI 1·174-1·234). There was a slight increase of hand eczema among smokers, PPR 1·025 (95% CI 1·006-1·044). Hand eczema was more common in individuals who reported stress, obesity and smoking. In individuals who reported high physical exercise levels hand eczema was less common. As there appears to be an association between life-style factors and hand eczema it is important to consider life-style factors in clinical practice. © 2011 The Authors.

Feudel, U.; Baurmann, M.; Gross, T.

2009-04-01

Spatio-temporal patterns in marine systems are a result of the interaction of population dynamics with physical transport processes. These physical transport processes can be either diffusion processes in marine sediments or in the water column. We study the dynamics of one population of bacteria and its nutrient in in a simplified model of a marine sediments, taking into account that the considered bacteria possess an active as well as an inactive state, where activation is processed by signal molecules. Furthermore the nutrients are transported actively by bioirrigation and passively by diffusion. It is shown that under certain conditions Turing patterns can occur which yield heterogeneous spatial patterns of the species. The influence of bioirrigation on Turing patterns leads to the emergence of ''hot spots``, i.e. localized regions of enhanced bacterial activity. All obtained patterns fit quite well to observed patterns in laboratory experiments. Spatio-temporal patterns appear in a predator-prey model, used to describe plankton dynamics. These patterns appear due to the simultaneous emergence of Turing patterns and oscillations in the species abundance in the neighborhood of a Turing-Hopf bifurcation. We observe a large variety of different patterns where i) stationary heterogeneous patterns (e.g. hot and cold spots) compete with spatio-temporal patterns ii) slowly moving patterns are embedded in an oscillatory background iii) moving fronts and spiral waves appear.

To identify the prevalence of a sedentary lifestyle in individuals with high blood pressure. This cross-sectional study was conducted among 310 individuals with high blood pressure. The prevalence of the diagnosis of sedentary lifestyle was 60%. The more common defining characteristics were "lack of physical conditioning" and "lack of practice for physical exercises." The nursing diagnosis was associated with age and presence of diabetes. Individuals who presented with a sedentary lifestyle related to lack of motivation were significantly younger. This study showed a high prevalence of "sedentary lifestyle" and its associations with age and the presence of diabetes. IMPLICATIONS TO NURSING PRACTICE: The acknowledgement of "sedentary lifestyle" contributes to the choice for nursing interventions that promote physical activity centered on the subject and the surroundings.

Cold urticaria: inhibition of cold-induced histamine release by doxantrazole.

Science.gov (United States)

Bentley-Phillips, C B; Eady, R A; Greaves, M W

1978-10-01

Thirteen patients with cold urticaria were studied to assess the effect of the systemic drug doxantrazole, which has actions resembling disodium cromoglycate, on cold evoked histamine release. The patients, all of whom developed an immediate local whealing response after cooling of the forearm, demonstrated release of histamine into venous blood draining that forearm. Following doxantrazole treatment, significant suppression of histamine release occurred. In some but not all patients this was accompanied by diminution of urtication in response to cooling. A double-blind study was carried out in 3 subjects, all of whom showed diminished cold-stimulated histamine release after doxantrazole. Two of these showed clinical improvement. Doxantrazole had no effect on erythema due to intradermal histamine, but did suppress the erythematous reaction to intradermal injection of compound 48/80. Our results suggest that doxantrazole or related anti-allergic agents might be useful in the treatment of cold urticaria.

Microbial diversity in cold seep sediments from the northern South China Sea

Full Text Available South China Sea (SCS is the largest Western Pacific marginal sea. However, microbial studies have never been performed in the cold seep sediments in the SCS. In 2004, “SONNE” 177 cruise found two cold seep areas with different water depth in the northern SCS. Haiyang 4 area, where the water depth is around 3000 m, has already been confirmed for active seeping on the seafloor, such as microbial mats, authigenic carbonate crusts and bivalves. We investigated microbial abundance and diversity in a 5.55-m sediment core collected from this cold seep area. An integrated approach was employed including geochemistry and 16S rRNA gene phylogenetic analyses. Here, we show that microbial abundance and diversity along with geochemistry profiles of the sediment core revealed a coupled reaction between sulphate reduction and methane oxidation. Acridine orange direct count results showed that microbial abundance ranges from 105 to 106 cells/g sediment (wet weight. The depth-related variation of the abundance showed the same trend as the methane concentration profile. Phylogenetic analysis indicated the presence of sulphate-reducing bacteria and anaerobic methane-oxidizing archaea. The diversity was much higher at the surface, but decreased sharply with depth in response to changes in the geochemical conditions of the sediments, such as methane, sulphate concentration and total organic carbon. Marine Benthic Group B, Chloroflexi and JS1 were predominant phylotypes of the archaeal and bacterial libraries, respectively.

Full Text Available Abstract Background Seagrasses are a polyphyletic group of monocotyledonous angiosperms that have adapted to a completely submerged lifestyle in marine waters. Here, we exploit two collections of expressed sequence tags (ESTs of two wide-spread and ecologically important seagrass species, the Mediterranean seagrass Posidonia oceanica (L. Delile and the eelgrass Zostera marina L., which have independently evolved from aquatic ancestors. This replicated, yet independent evolutionary history facilitates the identification of traits that may have evolved in parallel and are possible instrumental candidates for adaptation to a marine habitat. Results In our study, we provide the first quantitative perspective on molecular adaptations in two seagrass species. By constructing orthologous gene clusters shared between two seagrasses (Z. marina and P. oceanica and eight distantly related terrestrial angiosperm species, 51 genes could be identified with detection of positive selection along the seagrass branches of the phylogenetic tree. Characterization of these positively selected genes using KEGG pathways and the Gene Ontology uncovered that these genes are mostly involved in translation, metabolism, and photosynthesis. Conclusions These results provide first insights into which seagrass genes have diverged from their terrestrial counterparts via an initial aquatic stage characteristic of the order and to the derived fully-marine stage characteristic of seagrasses. We discuss how adaptive changes in these processes may have contributed to the evolution towards an aquatic and marine existence.

A strong positive cross-sectional relationship between BMI and a sedentary lifestyle has been consistently observed in numerous studies. However, it has been questioned whether high BMI is a determinant or a consequence of a sedentary lifestyle. Using data from four follow-ups of the University of North Carolina Alumni Heart Study, we examined the prospective associations between BMI and sedentary lifestyle in a cohort of 4595 middle-aged men and women who had responded to questionnaires at the ages of 41 (standard deviation 2.3), 44 (2.3), 46 (2.0), and 54 (2.0). BMI was consistently related to increased risk of becoming sedentary in both men and women. The odds ratios of becoming sedentary as predicted by BMI were 1.04 (95% confidence limits, 1.00, 1.07) per 1 kg/m(2) from ages 41 to 44, 1.10 (1.07, 1.14) from ages 44 to 46, and 1.12 (1.08, 1.17) from ages 46 to 54. Controlling for concurrent changes in BMI marginally attenuated the effects. Sedentary lifestyle did not predict changes in BMI, except when concurrent changes in physical activity were taken into account (p sedentary lifestyle but did not provide unambiguous evidence for an effect of sedentary lifestyle on weight gain.

A picture on the wall: innovative mapping reveals cold-water coral refuge in submarine canyon.

Directory of Open Access Journals (Sweden)

Veerle A I Huvenne

Full Text Available Cold-water corals are azooxanthellate species found throughout the ocean at water depths down to 5000 m. They occur in patches, reefs or large mound structures up to 380 m high, and as ecosystem engineers create important habitats for a diverse fauna. However, the majority of these habitats are now within reach of deep-sea bottom trawling. Many have been severely damaged or are under threat, despite recent protection initiatives. Here we present a cold-water coral habitat type that so far has been overlooked--quite literally--and that has received minimal impact from human activities. Vertical and overhanging cliffs in deep-sea canyons, revealed using an innovative approach to marine habitat mapping, are shown to provide the perfect substratum for extensive cold-water coral-based communities. Typical canyon-related processes, including locally enhanced internal tides and focussed downslope organic carbon transport, provide favourable environmental conditions (current regime, food input to sustain the communities, even outside the optimal depth and density envelopes reported elsewhere in the NE Atlantic. Our findings show that deep-sea canyons can form natural refuges for faunal communities sensitive to anthropogenic disturbance, and have the potential to fulfil the crucial role of larval sources for the recolonisation of damaged sites elsewhere on the margin.

A new cold neutron source at the HANARO Research Reactor had been constructed in the framework of a five-year project, and ended in 2009. It has seven neutron guides, among which five guides were already allocated for a number of neutron scattering instruments. A new two-year project to develop a Cold Neutron Activation Station (CONAS) was carried out at the two neutron guides since May 2010, which was supported by the program of the Ministry of Education, Science and Technology, Korea. Fig. 1 shows the location of CONAS. CONAS is a complex facility including several radioanalytical instruments utilizing neutron capture reaction to analyze elements in a sample. It was designed to include three instruments like a CN-PGAA (Cold Neutron - Prompt Gamma Activation Analysis), a CN-NIPS (Cold Neutron - Neutron Induced Pair Spectrometer), and a CN-NDP (Cold Neutron - Neutron-induced prompt charged particle Depth Profiling). Fig. 2 shows the conceptual configuration of the CONAS concrete bioshield and the instruments. CN-PGAA and CN-NIPS measure the gamma-rays promptly emitted from the sample after neutron capture, whereas CN-NDP is a probe to measure the charged particles emitted from the sample surface after neutron capture. For this, we constructed two cold neutron guides called CG1 and CG2B guides from the CNS

The Nav1.9 Channel Is a Key Determinant of Cold Pain Sensation and Cold Allodynia

Directory of Open Access Journals (Sweden)

Stéphane Lolignier

2015-05-01

Full Text Available Cold-triggered pain is essential to avoid prolonged exposure to harmfully low temperatures. However, the molecular basis of noxious cold sensing in mammals is still not completely understood. Here, we show that the voltage-gated Nav1.9 sodium channel is important for the perception of pain in response to noxious cold. Nav1.9 activity is upregulated in a subpopulation of damage-sensing sensory neurons responding to cooling, which allows the channel to amplify subthreshold depolarizations generated by the activation of cold transducers. Consequently, cold-triggered firing is impaired in Nav1.9−/− neurons, and Nav1.9 null mice and knockdown rats show increased cold pain thresholds. Disrupting Nav1.9 expression in rodents also alleviates cold pain hypersensitivity induced by the antineoplastic agent oxaliplatin. We conclude that Nav1.9 acts as a subthreshold amplifier in cold-sensitive nociceptive neurons and is required for the perception of cold pain under normal and pathological conditions.

Cold temperatures increase cold hardiness in the next generation Ophraella communa beetles.

Directory of Open Access Journals (Sweden)

Zhong-Shi Zhou

Full Text Available The leaf beetle, Ophraella communa, has been introduced to control the spread of the common ragweed, Ambrosia artemisiifolia, in China. We hypothesized that the beetle, to be able to track host-range expansion into colder climates, can phenotypically adapt to cold temperatures across generations. Therefore, we questioned whether parental experience of colder temperatures increases cold tolerance of the progeny. Specifically, we studied the demography, including development, fecundity, and survival, as well as physiological traits, including supercooling point (SCP, water content, and glycerol content of O. communa progeny whose parents were maintained at different temperature regimes. Overall, the entire immature stage decreased survival of about 0.2%-4.2% when parents experienced cold temperatures compared to control individuals obtained from parents raised at room temperature. However, intrinsic capacity for increase (r, net reproductive rate (R 0 and finite rate of increase (λ of progeny O. communa were maximum when parents experienced cold temperatures. Glycerol contents of both female and male in progeny was significantly higher when maternal and paternal adults were cold acclimated as compared to other treatments. This resulted in the supercooling point of the progeny adults being significantly lower compared to beetles emerging from parents that experienced room temperatures. These results suggest that cold hardiness of O. communa can be promoted by cold acclimation in previous generation, and it might counter-balance reduced survival in the next generation, especially when insects are tracking their host-plants into colder climates.

Background: The health model which forms the basis is knowledge, attitude, temporary, and permanent behaviors. Currently, more emphasis has been directed towards the combined influence of lifestyle, education, levels and socioeconomic factors, instead of regular risk factors in dealing with chronic illnesses. The present study is conducted to correlate the periodontal health of people with reference to lifestyle, education level, and socioeconomic status. Materials and Methods: A cross-sectional study was conducted in the Department of Periodontics, Narayana Dental College and Hospital, Nellore. A total of 1350 subjects were examined and 948 patients were randomly selected from out patient department. Information about their lifestyle, education level, and socioeconomic status were recorded using a questionnaire and correlated with the periodontal status. Results: The statistical analysis showed significant decrease in periodontitis when income and education levels increased. Also the prevalence of periodontitis associated with a healthy lifestyle is significantly lower when compared to an unhealthy lifestyle. Conclusions: There is a strong association of lifestyle, education level, and socioeconomic status with periodontal health. PMID:22114373

PHYSIOLOGICAL AND LEUKOCYTE SUBSET RESPONSES TO EXERCISE AND COLD EXPOSURE IN COLD-ACCLIMATIZED SKATERS

Full Text Available We investigated physiological responses and changes in circulating immune cells following exercise in cold and thermoneutral conditions. Participants were short track skaters (n=9 who were acclimatized to cold conditions, and inline skaters (n=10 who were not acclimatized. All skaters were young, and skating at a recreational level three days per week for at least one year. Using a cross-over design, study variables were measured during 60 min of submaximal cycling (65% ·VO2max in cold (ambient temperature: 5±1°C, relative humidity: 41±9% and thermoneutral conditions (ambient temperature: 21±1°C, relative humidity: 35±5%. Heart rate, blood lactate and tympanic temperature were measured at rest, during exercise and recovery. Plasma cortisol, calprotectin and circulating blood cell numbers were measured before and after 60 min of cold or thermoneutral conditions, and during recovery from exercise. Heart rate was lower in both groups during exercise in cold versus thermoneutral conditions (P<0.05. The increase in total leukocytes during recovery was primarily due to an increase in neutrophils in both groups. The cold-acclimatized group activated neutrophils after exercise in cold exposure, whereas the non-acclimatized group activated lymphocyte and cortisol after exercise in cold exposure. Lymphocyte subsets significantly changed in both groups over time during recovery as compared to rest. Immediately after exercise in both groups, CD16+ and CD69+ cells were elevated compared to rest or before exercise in both conditions. Acclimatization to exercise in the cold does not appear to influence exercise-induced immune changes in cold conditions, with the possible exception of neutrophils, lymphocytes and cortisol concentration.

Thomas, Kristin; Bendtsen, Preben; Krevers, Barbro

2014-11-01

To explore and theorize how patients perceive, interpret, and reactin healthy lifestyle promotion situations in primary care and to investigate patients' role in implementation of lifestyle promotion illustrated by typologies. Grounded theory was used to assess qualitative interview data from 22 patients with varied experience of healthy lifestyle promotion. Data were analyzed by constant comparative analysis. A substantive theory of being healthy emerged from the data. The theory highlights the processes that are important for implementation before, during, and after lifestyle promotion. Three interconnected categories emerged from the data: conditions for being healthy, managing being healthy, and interactions about being healthy; these formed the core category: being healthy. A typology proposed four patient trajectories on being healthy: resigned, receivers, coworkers, and leaders. Patients coproduced the implementation of lifestyle promotion through the degree of transparency, which was a result of patients' expectations and situation appraisals.

(1) to study preconception lifestyle changes and associated factors in women with planned pregnancies; (2) to assess the prevalence of risk factors for adverse pregnancy outcomes in women not reporting any preconception lifestyle changes; and (3) to explore the need for and use of preconception-related advice. secondary data analysis of a cross-sectional study about pregnancy planning. six Flemish Hospitals (Belgium). four hundred and thirty women with a planned pregnancy ending in birth. preconception lifestyle changes were measured during the first 5 days postpartum using the validated London Measure of Unplanned Pregnancy. The following changes were assessed: folic acid or multivitamin intake, smoking reduction or cessation, alcohol reduction or cessation, caffeine reduction or cessation, eating more healthily, achieving a healthier weight, obtaining medical or health advice, or another self-reported preconception lifestyle change. most women (83%) that planned their pregnancy reported ≥1 lifestyle change in preparation for pregnancy. Overall, nulliparous women (OR 2.18, 95% CI 1.23-3.87) and women with a previous miscarriage (OR 2.44, 95% CI 1.14-5.21) were more likely to prepare for pregnancy, while experiencing financial difficulties (OR 0.20, 95% CI 0.04-0.97) or having a lower educational level (OR 0.56, 95% CI 0.32-0.99) decreased the likelihood of preparing for pregnancy. Half of the women (48%) obtained advice about preconception health, and 86% of these women received their advice from a professional caregiver. Three-quarters (77%) of the women who did not improve their lifestyle before conceiving reported one or more risk factors for adverse pregnancy outcomes. multiparous women and women of lower socio-economic status were less likely to change their lifestyle before conception. Strategies to promote preconception health in these women need to be tailored to their needs and characteristics to overcome barriers to change. It may be advantageous to

Full Text Available Due to the rapid growth of the industries and constantly involvement of the new technologies into the human lives, the lifestyles of the people are altering. Simultaneously few new disorders in their lifestyles and diseases in their lives are also emerging. The spinal cord abnormalities i.e., the spinal disc herniation and/or low back pain is one of them which have made the life of some people very miserable (Farahani et al., 2012. Indeed the overall lifestyle of a human being regulates the musculoskeletal symptoms. Differences in lifestyle and psychosocial factors associated with individuals' lifestyle are effective in experiencing the level of pressure in musculoskeletal systems. Studies related to the lifestyle and musculoskeletal system, including pain and inflammation, are largely correlate (Mikkonen et al., 2015. Proper knowledge regarding the relationship between lifestyle and spinal disc herniation is very important. Social habits such as diet, exercise, weight gain, anxiety, and depression can cause changes in the spinal cord and spinal disc herniation (Kadow et al., 2014. Further, some of the lifestyle parameters such as smoking, nutrition, BMI, level of activity, sleep status, stress, and anxiety are also seen to reduce the need for medication or avoid and reduce musculoskeletal pain (Dean et al., 2015. As per Bohman et al. (2014 people with a healthy lifestyle suffer 66% less from low back pain than those who have unhealthy lifestyles.

Full Text Available The cold-water coral Lophelia pertusa is one of the few species able to build reef-like structures and a 3-dimensional coral framework in the deep oceans. Furthermore, deep cold-water coral bioherms may be among the first marine ecosystems to be affected by ocean acidification. Colonies of L. pertusa were collected during a cruise in 2006 to cold-water coral bioherms of the Mingulay reef complex (Hebrides, North Atlantic. Shortly after sample collection onboard these corals were labelled with calcium-45. The same experimental approach was used to assess calcification rates and how those changed due to reduced pH during a cruise to the Skagerrak (North Sea in 2007. The highest calcification rates were found in youngest polyps with up to 1% d−1 new skeletal growth and average rates of 0.11±0.02% d−1±S.E.. Lowering pH by 0.15 and 0.3 units relative to the ambient level resulted in calcification being reduced by 30 and 56%. Lower pH reduced calcification more in fast growing, young polyps (59% reduction than in older polyps (40% reduction. Thus skeletal growth of young and fast calcifying corallites suffered more from ocean acidification. Nevertheless, L. pertusa exhibited positive net calcification (as measured by 45Ca incorporation even at an aragonite saturation state (Ωa below 1.

The relationship between lifestyle regularity and subjective sleep quality

Monk, Timothy H.; Reynolds, Charles F 3rd; Buysse, Daniel J.; DeGrazia, Jean M.; Kupfer, David J.

2003-01-01

In previous work we have developed a diary instrument-the Social Rhythm Metric (SRM), which allows the assessment of lifestyle regularity-and a questionnaire instrument--the Pittsburgh Sleep Quality Index (PSQI), which allows the assessment of subjective sleep quality. The aim of the present study was to explore the relationship between lifestyle regularity and subjective sleep quality. Lifestyle regularity was assessed by both standard (SRM-17) and shortened (SRM-5) metrics; subjective sleep quality was assessed by the PSQI. We hypothesized that high lifestyle regularity would be conducive to better sleep. Both instruments were given to a sample of 100 healthy subjects who were studied as part of a variety of different experiments spanning a 9-yr time frame. Ages ranged from 19 to 49 yr (mean age: 31.2 yr, s.d.: 7.8 yr); there were 48 women and 52 men. SRM scores were derived from a two-week diary. The hypothesis was confirmed. There was a significant (rho = -0.4, p subjects with higher levels of lifestyle regularity reported fewer sleep problems. This relationship was also supported by a categorical analysis, where the proportion of "poor sleepers" was doubled in the "irregular types" group as compared with the "non-irregular types" group. Thus, there appears to be an association between lifestyle regularity and good sleep, though the direction of causality remains to be tested.

Effects of cold temperatures on the excitability of rat trigeminal ganglion neurons that are not for cold-sensing

Science.gov (United States)

Kanda, Hirosato; Gu, Jianguo G.

2016-01-01

Except a small population of primary afferent neurons for sensing cold to generate the sensations of innocuous and noxious cold, it is generally believed that cold temperatures suppress the excitability of other primary afferent neurons that are not for cold-sensing. These not-for-cold-sensing neurons include the majority of non-nociceptive and nociceptive afferent neurons. In the present study we have found that not-for-cold-sensing neurons of rat trigeminal ganglia (TG) change their excitability in several ways at cooling temperatures. In nearly 70% of not-for-cold-sensing TG neurons, the cooling temperature of 15°C increases their membrane excitability. We regard these neurons as cold-active neurons. For the remaining 30% of not-for-cold-sensing TG neurons, the cooling temperature of 15°C either has no effect (regarded as cold-ineffective neurons) or suppress (regarded as cold-suppressive neurons) their membrane excitability. For cold-active neurons, the cold temperature of 15°C increases their excitability as is evidenced by the increases in action potential (AP) firing numbers and/or reduction of AP rheobase when these neurons are depolarized electrically. The cold temperature of 15°C significantly inhibits M-currents and increases membrane input resistance of cold-active neurons. Retigabine, an M-current activator, abolishes the effect of cold temperatures on AP firing but not the effect of cold temperature on AP rheobase levels. The inhibition of M-currents and the increases of membrane input resistance are likely two mechanisms by which cooling temperatures increase the excitability of not-for-cold-sensing TG neurons.

Cold-triggered pain is essential to avoid prolonged exposure to harmfully low temperatures. However, the molecular basis of noxious cold sensing in mammals is still not completely understood. Here, we show that the voltage-gated Nav1.9 sodium channel is important for the perception of pain in response to noxious cold. Nav1.9 activity is upregulated in a subpopulation of damage-sensing sensory neurons responding to cooling, which allows the channel to amplify subthreshold depolarizations generated by the activation of cold transducers. Consequently, cold-triggered firing is impaired in Nav1.9(-/-) neurons, and Nav1.9 null mice and knockdown rats show increased cold pain thresholds. Disrupting Nav1.9 expression in rodents also alleviates cold pain hypersensitivity induced by the antineoplastic agent oxaliplatin. We conclude that Nav1.9 acts as a subthreshold amplifier in cold-sensitive nociceptive neurons and is required for the perception of cold pain under normal and pathological conditions.

Full Text Available Tamar ShochatDepartment of Nursing, Faculty of Social Welfare and Health Sciences, University of Haifa, Haifa, IsraelAbstract: Although the physiological and psychological mechanisms involved in the development of sleep disorders remain similar throughout history, factors that potentiate these mechanisms are closely related to the "zeitgeist", ie, the sociocultural, technological and lifestyle trends which characterize an era. Technological advancements have afforded modern society with 24-hour work operations, transmeridian travel and exposure to a myriad of electronic devices such as televisions, computers and cellular phones. Growing evidence suggests that these advancements take their toll on human functioning and health via their damaging effects on sleep quality, quantity and timing. Additional behavioral lifestyle factors associated with poor sleep include weight gain, insufficient physical exercise and consumption of substances such as caffeine, alcohol and nicotine. Some of these factors have been implicated as self-help aids used to combat daytime sleepiness and impaired daytime functioning. This review aims to highlight current lifestyle trends that have been shown in scientific investigations to be associated with sleep patterns, sleep duration and sleep quality. Current understanding of the underlying mechanisms of these associations will be presented, as well as some of the reported consequences. Available therapies used to treat some lifestyle related sleep disorders will be discussed. Perspectives will be provided for further investigation of lifestyle factors that are associated with poor sleep, including developing theoretical frameworks, identifying underlying mechanisms, and establishing appropriate therapies and public health interventions aimed to improve sleep behaviors in order to enhance functioning and health in modern society.Keywords: sleep, technology, lifestyle, behavior

Allergic diseases develop in genetically susceptible individuals in a complex interplay with the environment, usually early in life. We have previously shown that the anthroposophic lifestyle is associated with reduced risk of allergic disease in children, but details on the influencing environmental factors are largely unknown. This study aims to elucidate if anthroposophic lifestyle influences fetal exposure to selected toxic and essential elements. Randomly selected non-smoking mothers with (n=40) and without (n=40) anthroposophic lifestyle from the prospective birth cohort ALADDIN were included. Concentrations of 12 toxic and essential elements were analyzed in full term placentas and in the erythrocyte fractions of maternal peripheral blood and of umbilical cord blood, using inductively coupled plasma mass spectrometry. Cadmium concentrations in maternal blood and placenta were significantly higher in mothers with an anthroposophic lifestyle (p<0.001), while concentrations in cord blood were generally low, irrespective of lifestyle. Cobalt concentrations were higher in both maternal blood, placenta and cord blood in the anthroposophic group. Lead concentrations were higher in maternal blood and cord blood, but not placenta, of mothers with anthroposophic lifestyle. Analysis of covariance, including lifestyle, parity, maternal age, gestational age, vegetarian diet, use of herbal medicine and occupation in the model, showed that mainly the anthroposophic lifestyle was significantly associated with cadmium concentrations. In conclusion, women with an anthroposophic lifestyle had higher concentrations of cadmium, cobalt and lead concentrations. Cadmium concentrations might have been influenced by a diet rich in vegetables and/or low iron status of the mothers. - Highlights: • Toxic elements in mother–newborn pairs in relation to anthroposophic lifestyle. • Anthroposophic lifestyle was associated with higher levels of cadmium, cobalt and lead. • A diet rich

Abel, T

1991-01-01

The concept of lifestyle bears great potential for research in medical sociology. Yet, weaknesses in current methods have restrained lifestyle research from realizing its full potentials. The present focus is on the links between theoretical conceptions and their empirical application. The paper divides into two parts. The first part provides a discussion of basic theoretical and methodological issues. In particular selected lines of thought from Max Weber are presented and their usefulness in providing a theoretical frame of reference for health lifestyle research is outlined. Next, a theory guided definition of the subject matter is introduced and basic problems in empirical applications of theoretical lifestyle concepts are discussed. In its second part the paper presents findings from comparative lifestyle analyses. Data from the U.S. and West Germany are utilized to explore issues of measurement equivalence and theoretical validity. Factor analyses indicate high conceptual equivalence for new measures of health lifestyle dimensions in both the U.S. and West Germany. Divisive cluster analyses detect three distinct lifestyle groups in both nations. Implications for future lifestyle research are discussed.

The manufacture of lifestyle: the role of corporations in unhealthy living.

Science.gov (United States)

Freudenberg, Nicholas

2012-05-01

Recently, researchers have debated two views on the connection between lifestyle and health. In the first, health-related lifestyles including tobacco and alcohol use, diet, and physical activity are seen as primary influences on health. In the second, social stratification is the dominant influence with lifestyles simply markers of social status. Neither approach leads to interventions that can reverse the world's most serious health problems. This article proposes that corporate practices are a dominant influence on the lifestyles that shape patterns of health and disease. Modifying business practices that promote unhealthy lifestyles is a promising strategy for improving population health. Corporations shape lifestyles by producing and promoting healthy or unhealthy products, creating psychological desires and fears, providing health information, influencing social and physical environments, and advancing policies that favor their business goals. Public officials and health professionals can promote health by advocating policies to modify these corporate practices.

Limited knowledge is available on lifestyle patterns in Spanish adults. We investigated dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, sleep time, and smoking in Spanish adults aged 18-64 years and their association with obesity. Analysis was based on a subsample ( n = 1617) of the cross-sectional ANIBES study in Spain. We performed exploratory factor analysis and subsequent cluster analysis of dietary patterns, physical activity, sedentary behaviors, sleep time, and smoking. Logistic regression analysis was used to explore the association between the cluster solutions and obesity. Factor analysis identified four dietary patterns, " Traditional DP ", " Mediterranean DP ", " Snack DP " and " Dairy-sweet DP ". Dietary patterns, physical activity behaviors, sedentary behaviors, sleep time, and smoking in Spanish adults aggregated into three different clusters of lifestyle patterns: " Mixed diet-physically active-low sedentary lifestyle pattern ", " Not poor diet-low physical activity-low sedentary lifestyle pattern " and " Poor diet-low physical activity-sedentary lifestyle pattern ". A higher proportion of people aged 18-30 years was classified into the " Poor diet-low physical activity-sedentary lifestyle pattern ". The prevalence odds ratio for obesity in men in the " Mixed diet-physically active-low sedentary lifestyle pattern " was significantly lower compared to those in the " Poor diet-low physical activity-sedentary lifestyle pattern ". Those behavior patterns are helpful to identify specific issues in population subgroups and inform intervention strategies. The findings in this study underline the importance of designing and implementing interventions that address multiple health risk practices, considering lifestyle patterns and associated determinants.

Cold fusion

Koster, J.

1989-01-01

In this contribution the author the phenomenom of so-called cold fusion, inspired by the memorable lecture of Moshe Gai on his own search for this effect. Thus much of what follows was presented by Dr. Gai; the rest is from independent reading. What is referred to as cold fusion is of course the observation of possible products of deuteron-deuteron (d-d) fusion within deuterium-loaded (dentended) electrodes. The debate over the two vanguard cold fusion experiments has raged under far more public attention than usually accorded new scientific phenomena. The clamor commenced with the press conference of M. Fleishmann and S. Pons on March 23, 1989 and the nearly simultaneous wide circulation of a preprint of S. Jones and collaborators. The majority of work attempting to confirm these observations has at the time of this writing yet to appear in published form, but contributions to conferences and electronic mail over computer networks were certainly filled with preliminary results. To keep what follows to a reasonable length the author limit this discussion to the searches for neutron (suggested by ref. 2) or for excessive heat production (suggested by ref. 1), following a synopsis of the hypotheses of cold fusion

To compare different definitions of a sedentary lifestyle and to determine which is the most appropriate for demonstrating its relationship with the metabolic syndrome and other cardiovascular risk factors. A cross-sectional study of 5814 individuals was carried out. Comparisons were made between two definitions of a sedentary lifestyle: one based on active energy expenditure being less than 10% of total energy expenditure, and the other, on performing less than 25-30 minutes of physical activity per day. Reported levels of physical activity, anthropometric measurements, and biochemical markers of cardiovascular risk were recorded. The associations between a sedentary lifestyle and metabolic syndrome and other risk factors were adjusted for gender, age and tobacco use. The prevalence of a sedentary lifestyle was higher in women (70%) than in men (45-60%, according to the definition used). The definitions based on physical activity duration and on energy expenditure were equally useful: there were direct associations between a sedentary lifestyle and metabolic syndrome, body mass index, abdominal and pelvic circumferences, systolic blood pressure, heart rate, apolipoprotein B, and triglycerides, and inverse associations with high-density lipoprotein cholesterol and paraoxonase activity, which demonstrated the greatest percentage difference between sedentary and active individuals. An incidental finding was that both definitions of a sedentary lifestyle were more strongly associated with the metabolic syndrome as defined by International Diabetes Federation criteria than by Adult Treatment Panel III criteria. Given that it is relatively easy to determine whether a patient performs less than 25 minutes of physical activity per day, use of this definition of a sedentary lifestyle is recommended for clinical practice. The serum paraoxonase activity level could provide a useful marker for studying sedentary lifestyles.

Background Lifestyle and dietary advice typically precedes or accompanies the prescription of statin medications. However, evidence for adherence to this advice is sparse. The objective was to compare saturated fat intake, exercise, alcohol consumption and smoking between statin users and non-users in Australia. Methods Data were analysed for 4614 participants aged ≥37 years in the Australian Diabetes, Obesity and Lifestyle study in 2011-2012. Statin use, smoking status and physical activity were self-reported. Saturated fat and alcohol intake were measured via a food frequency questionnaire. Multinomial logistic regression was used to compute adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between statin use and the four lifestyle factors. All models were adjusted for age, sex, education, number of general practitioner visits, body mass index, hypertension, diabetes and prior cardiovascular diseases. Results In total 1108 (24%) participants used a statin. Statin users were 29% less likely to be within the highest quartile versus the lowest quartile of daily saturated fat intake compared to non-users (OR 0.71, 95% CI 0.54-0.94). There were no statistically significant associations between statin use and smoking, physical activity or alcohol consumption. Conclusions Smoking status, alcohol consumption and exercise level did not differ between users and non-users of statins. However, statin users were less likely to consume high levels of saturated fat than non-users. We found no evidence that people took statins to compensate for a poor diet or lifestyle.

Adherence to a Mediterranean dietary pattern is a well-established protective factor against cardiovascular disease (CVD). However, diet quality is only one aspect of the overall healthy lifestyle adopted by Mediterranean populations. The latter has never been evaluated as a multi-factorial composite lifestyle. Thus, the aim of the present study was to provide a broader picture of the Mediterranean lifestyle and its effects on CVD risk, among elderly individuals. During 2005-2015, 2,749 older (aged 65-100 years) from 21 Mediterranean islands (MEDIS) and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled onto the study. Dietary habits, physical activity status, socio-demographic characteristics, lifestyle parameters (sleep, smoking habits, social life and educational status) and clinical profile aspects were derived through standard procedures. The overall prevalence of the traditional CVD risk factors were 62.3% for hypertension, 22.3% for diabetes mellitus (type 2) and 47.7% for hypercholesterolemia. The presence of diabetes mellitus was positively predicted by the geriatric depression scale (GDS) [odds ratio (OR) =1.13, 95% confidence interval (CI): 1.02-1.25] and by an urban residential environment (OR =2.57, 95% CI: 1.10-6.06) after adjusting for several confounders. Presence of hypertension was predicted by increasing age (OR =1.07, 95% CI: 1.02-1.12), increasing body mass index (BMI) (OR =1.12, 95% CI: 1.04-1.21), the habit of midday sleep (OR =2.07, 95% CI: 1.07-4.02) and inversely predicted by the frequency of socializing with friends (OR =0.767, 95% CI: 0.616-0.955). The estimated score in the GDS was the only independent positive predictor for the presence of hypercholesterolemia (OR =1.10, 95% CI: 1.01-1.21). Lifestyle parameters such as social life, midday sleep (siesta) and residential environment are strongly associated with the presence of CVD risk factors in elderly and should be part of broader CVD prevention strategies to

Personal lifestyle, including diet, exercise, and sleep, might have an impact on work engagement, though previous studies have not focused on these relationships. The aim of this study was to examine whether dietary intake of fish, regular exercise, sufficient sleep, abstinence from alcohol, and abstinence from tobacco were positively associated with work engagement. We recruited adults aged 40-74 years who attended the health checkups with a particular focus on the metabolic syndrome in central Tokyo. In December 2015, 797 people responded to a questionnaire and 592 (74.3%) who had regular jobs were selected for this study. Work engagement was assessed on the 9-item Utrecht Work Engagement Scale (UWES-9). Bivariate and multivariate regression analyses were performed to examine the relationships between lifestyle and UWES-9. Dietary intake of fish, regular exercise, sufficient sleep, and abstinence from tobacco were significantly correlated with the total UWES-9 score, even after adjusting for age, sex, and depressive and anxiety symptoms. The results suggested a dose-response relationship between dietary fish intake and work engagement. Dietary fish intake, regular exercise, sufficient sleep, and abstinence from tobacco might be lifestyle factors that can serve as resources for work engagement. These findings could be useful in motivating employees to make lifestyle improvements and convincing employers and managers that lifestyle is important not only for health but also for productivity.

Although social capital as a key determinant of health has been well established in various studies, little is known about how lifestyle factors mediate this relationship. Understanding the cross-relationships between social capital, health, and lifestyle factors is important if health promotion policies are to be effective. The purpose of this study is to explore whether different dimensions of social capital and lifestyle factors are related, and whether lifestyle factors mediate the association between social capital and self-rated health (SRH) and psychological well-being (PWB) in China. This study used nationally representative data from the 2014 China Family Panel Studies (n = 28,916). The data reported on three dimensions of individual-level social capital: social trust, social relationship and Chinese Communist Party (CCP) membership. Health was assessed using SRH and PWB. Five lifestyle indicators were recorded: healthy diet, physical activity, smoking, sleeping, and non-overweight status. Logistic regression was used to examine the associations between social capital and lifestyle factors, and whether there was a mediating role of lifestyle. Odds ratios relating health status to social capital were reported before and after adjustment for lifestyle factors. Mediation analysis was then used to calculate the total, direct and indirect effects of social capital on SRH and PWB. The results show that social trust was significantly associated with all five lifestyle factors. Social relationship was significantly associated with four of the five: healthy diet, physical activity, sleeping and non-overweight. CCP membership was only significantly associated with two lifestyle factors: physical activity and non-overweight. Social trust and social relationship were significantly related to both SRH and PWB. CCP membership was only significantly related to SRH. Mediation analysis found modest evidence that lifestyle factors influenced the relationship between all

Although Earth's climate history is best known through marine records, the corresponding continental climatic conditions drive the evolution of terrestrial life. Continental conditions during the latest Miocene are of particular interest because global faunal turnover is roughly synchronous with a period of global glaciation from ∼6.2-5.5 Ma and with the Messinian Salinity Crisis from ∼6.0-5.3 Ma. Despite the climatic and ecological significance of this period, the continental climatic conditions associated with it remain unclear. We address this question using erosion rates of ancient watersheds to constrain Mio-Pliocene climatic conditions in the south-central Andes near 30° S. Our results show two slowdowns in erosion rate, one from ∼6.1-5.2 Ma and another from 3.6 to 3.3 Ma, which we attribute to periods of continental aridity. This view is supported by synchrony with other regional proxies for aridity and with the timing of glacial ‟cold" periods as recorded by marine proxies, such as the M2 isotope excursion. We thus conclude that aridity in the south-central Andes is associated with cold periods at high southern latitudes, perhaps due to a northward migration of the Southern Hemisphere westerlies, which disrupted the South American Low Level Jet that delivers moisture to southeastern South America. Colder glacial periods, and possibly associated reductions in atmospheric CO 2 , thus seem to be an important driver of Mio-Pliocene ecological transitions in the central Andes. Finally, this study demonstrates that paleo-erosion rates can be a powerful proxy for ancient continental climates that lie beyond the reach of most lacustrine and glacial archives.

The boundary layer moist static energy budget: Convection picks up moisture and leaves footprints in the marine boundary layer

de Szoeke, S. P.

2017-12-01

Averaged over the tropical marine boundary layer (BL), 130 W m-2 turbulent surface moist static energy (MSE) flux, 120 W m-2 of which is evaporation, is balanced by upward MSE flux at the BL top due to 1) incorporation of cold air by downdrafts from deep convective clouds, and 2) turbulent entrainment of dry air into the BL. Cold saturated downdraft air, and warm clear air entrained into the BL have distinct thermodynamic properties. This work observationally quantifies their respective MSE fluxes in the central Indian Ocean in 2011, under different convective conditions of the intraseasonal (40-90 day) Madden Julian oscillation (MJO). Under convectively suppressed conditions, entrainment and downdraft fluxes export equal shares (60 W m-2) of MSE from the BL. Downdraft fluxes are more variable, increasing for stronger convection. In the convectively active phase of the MJO, downdrafts export 90 W m-2 from the BL, compared to 40 W m-2 by entrainment. These processes that control the internal, latent (condensation), and MSE of the tropical marine atmospheric BL determine the parcel buoyancy and strength of tropical deep convection.

Cold acclimation and cognitive performance: A review.

Jones, Douglas M; Bailey, Stephen P; Roelands, Bart; Buono, Michael J; Meeusen, Romain

2017-12-01

Athletes, occupational workers, and military personnel experience cold temperatures through cold air exposure or cold water immersion, both of which impair cognitive performance. Prior work has shown that neurophysiological pathways may be sensitive to the effects of temperature acclimation and, therefore, cold acclimation may be a potential strategy to attenuate cold-induced cognitive impairments for populations that are frequently exposed to cold environments. This review provides an overview of studies that examine repeated cold stress, cold acclimation, and measurements of cognitive performance to determine whether or not cold acclimation provides beneficial protection against cold-induced cognitive performance decrements. Studies included in this review assessed cognitive measures of reaction time, attention, logical reasoning, information processing, and memory. Repeated cold stress, with or without evidence of cold acclimation, appears to offer no added benefit of improving cognitive performance. However, research in this area is greatly lacking and, therefore, it is difficult to draw any definitive conclusions regarding the use of cold acclimation to improve cognitive performance during subsequent cold exposures. Given the current state of minimal knowledge on this topic, athletes, occupational workers, and military commands looking to specifically enhance cognitive performance in cold environments would likely not be advised to spend the time and effort required to become acclimated to cold. However, as more knowledge becomes available in this area, recommendations may change. Copyright © 2017 Elsevier B.V. All rights reserved.

Adaptation and evolution in marine environments. Vol. 2. The impacts of global change on biodiversity

2013-02-01

Offers a regionally focussed approach. Describes research on adaptive evolution. State-of-the-art content. The second volume of ''Adaptation and Evolution in Marine Environments - The Impacts of Global Change on Biodiversity'' from the series ''From Pole to Pole'' integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea. The speed and extent of warming in the Arctic and in regions of Antarctica (the Peninsula, at the present) are greater than elsewhere. Changes impact several parameters, in particular the extent of sea ice; organisms, ecosystems and communities that became finely adapted to increasing cold in the course of millions of years are now becoming vulnerable, and biodiversity is threatened. Investigating evolutionary adaptations helps to foresee the impact of changes in temperate areas, highlighting the invaluable contribution of polar marine research to present and future outcomes of the IPY in the Earth system scenario.

What is the cost-effectiveness of lifestyle intervention preceding infertility treatment in obese infertile women? Lifestyle intervention preceding infertility treatment as compared to prompt infertility treatment in obese infertile women is not a cost-effective strategy in terms of healthy live birth rate within 24 months after randomization, but is more likely to be cost-effective using a longer follow-up period and live birth rate as endpoint. In infertile couples, obesity decreases conception chances. We previously showed that lifestyle intervention prior to infertility treatment in obese infertile women did not increase the healthy singleton vaginal live birth rate at term, but increased natural conceptions, especially in anovulatory women. Cost-effectiveness analyses could provide relevant additional information to guide decisions regarding offering a lifestyle intervention to obese infertile women. The cost-effectiveness of lifestyle intervention preceding infertility treatment compared to prompt infertility treatment was evaluated based on data of a previous RCT, the LIFEstyle study. The primary outcome for effectiveness was the vaginal birth of a healthy singleton at term within 24 months after randomization (the healthy live birth rate). The economic evaluation was performed from a hospital perspective and included direct medical costs of the lifestyle intervention, infertility treatments, medication and pregnancy in the intervention and control group. In addition, we performed exploratory cost-effectiveness analyses of scenarios with additional effectiveness outcomes (overall live birth within 24 months and overall live birth conceived within 24 months) and of subgroups, i.e. of ovulatory and anovulatory women, women birth rates were 27 and 35% in the intervention group and the control group, respectively (effect difference of -8.1%, P birth rate. Mean costs per healthy live birth event were €15 932 in the intervention group and €15 912 in the

Full Text Available Introduction: Lifestyle modification is one of the methods to promote healthy lifestyle among adolescents. In this study, the researcher planned to develop, implement and evaluate a need based Participatory Adolescent Strategic Health Action (PASHA for lifestyle modification among selected adolescents. Materials and Methods: An evaluative approach with Quasi experimental one group pretest post test design (time series was adopted. Sample constituted 103 adolescents, aged 12-17 years studying in high schools and pre university colleges of Udupi district selected based on convenient sampling. Data was gathered using reliable and valid tools. Results: The mean combined preventive health lifestyle score among all adolescents increased from 75.65-81.56. Similarly the number of adolescents with healthy lifestyle score also increased from 28.2-53.4% after practicing for 180 days. Analysis of all the components of lifestyle showed that the adolescents had adopted healthy lifestyle practices in all the components of lifestyle. The number of adolescents with combined health status score also showed an increase from 31.1-54.4% after implementing PASHA practice. Analysis of reported outcome among subjects indicated that PASHA was motivating to improve their lifestyle practices. Conclusion: PASHA was found to be effective in lifestyle modification of adolescents. It is reiterated that when lifestyle modification is to be done, a strategy to improve self directedness and self efficacy should be adopted.

To examine nurses' health-promoting lifestyle behaviors, describe their self-reported engagement in employee wellness program benefit options, and explore relationships between nurse demographic factors, health characteristics and lifestyle behaviors. Nurses adopting unhealthy lifestyle behaviors are at significantly higher risk for developing a number of chronic diseases and are at increased susceptibility to exhaustion, job dissatisfaction and turnover. Strengthening professional nurses' abilities to engage in healthy lifestyle behaviors could serve as a valuable tool in combating negative workplace stress, promote improved work-life balance and personal well-being, and help retain qualified health-care providers. In a 187-bed community hospital in the Washington D.C. metropolitan area, we conducted an IRB-approved exploratory descriptive study. We examined 127 nurses' demographic characteristics, self-reported employer wellness program use, and measured their healthy lifestyle behaviors using the 52-item Health-Promoting Lifestyle Profile-II (HPLP-II) survey instrument. Nurse demographic and HPLP-II scores were analyzed in SPSS v20.0. Inferential univariate statistical testing examined relationships between nurse demographic factors, health and job characteristics, and HPLP-II score outcomes. Nurses over 40years old were more likely to report participation in hospital wellness program options. Statistically significant age differences were identified in total HPLP-II score (p=0.005), and two subscale scores-spiritual growth (p=0.002) and interpersonal relations (p=0.000). Post-hoc testing identified nurse participants 40-49years old and ≥50years old experienced slightly lower total HPLP-II score, subscale scores in comparison to younger colleagues. Nurses ≥40years old may benefit from additional employer support and guidance to promote and maintain healthy lifestyles, personal well-being, and positive interpersonal relationships.

Full Text Available Background & objectives: Male reproductive function in the general population has been receiving attention in recent years due to reports of various reproductive and developmental defects, which might be associated with various lifestyle and environmental factors. This study was carried out to determine the role of various lifestyle and environmental factors in male reproduction and their possible association with declining semen quality, increased oxidative stress as well as sperm DNA damage. Methods: Semen samples were obtained from 240 male partners of the couples consulting for infertility problem. Semen analysis was carried out using WHO criteria and subjects were categorized on the basis of self reported history of lifestyle as well as environmental exposure. The oxidative and antioxidant markers; lipid peroxidation (LPO, superoxide dismutase (SOD and catalase (CAT as well as DNA damage by acridine orange test (AO were determined. Results: The presence of abnormal semen parameters was significantly higher among the lifestyle and/or environmental exposed subjects as compared to the non-exposed population. Further, the levels of antioxidants were reduced and sperm DNA damage was more among the lifestyle and/or environmental exposed subjects, though the changes were not significant. Interpretation & conclusions: These findings indicated that various lifestyle factors such as tobacco smoking, chewing and alcohol use as well as exposure to toxic agents might be attributed to the risk of declining semen quality and increase in oxidative stress and sperm DNA damage.

"Cold" Fixation: Reconciliation of Nitrogen Fixation Rates and Diazotroph Assemblages in the Arctic Ocean

Fong, A. A.; Waite, A.; Rost, B.; Richter, K. U.

Measurements of biological nitrogen fixation are typically conducted in oligotrophic subtropical and tropical marine environments where concentrations of fixed inorganic nitrogen are low. To date, only a handful of nitrogen fixation studies have been conducted in high latitude marine environments, but further investigation is needed to resolve the distribution of cold ocean diazotrophic assemblages. Nitrogen fixation rates and nifH gene distributions were measured at seven stations from 5°E to 20°E, north of 81°N in the Arctic Ocean at the onset of summer 2015. Discrete water samples in ice-covered regions were collected from the sea surface to 200 m for 15N2-tracer additions and targeted nifH gene and transcript analyses. Previous work suggests that heterotrophic bacteria dominate diazotrophic communities in the Arctic Ocean. Therefore, additional nifH gene surveys of sinking particles were conducted to test for enrichment on organic matter-rich microenvironments. Together, these measurements aim to reconcile diazotrophic activity with microbial community composition, further elucidating how nitrogen fixers could impact current concepts in polar carbon and nutrient cycling.

To examine the relationship between a general measure of chronic life stress and atherosclerosis among middle aged adults without clinical cardiovascular disease via pathways through unhealthy lifestyle characteristics. We conducted an analysis of The Multi-Ethnic Study of Atherosclerosis (MESA). The MESA collected in 2000 includes 5,773 participants, aged 45-84. We computed standard regression techniques to examine the relationship between life stress and atherosclerosis as well as path analysis with hypothesized paths from stress to atherosclerosis through unhealthy lifestyle. Our outcome was sub-clinical atherosclerosis measured as presence of coronary artery calcification (CAC). A logistic regression adjusted for potential confounding variables along with the unhealthy lifestyle characteristics of smoking, excessive alcohol use, high caloric intake, sedentary lifestyle, and obesity yielded no significant relationship between chronic life stress (OR 0.93, 95% CI 0.80-1.08) and CAC. However, significant indirect pathways between chronic life stress and CAC through smoking (p = .007), and sedentary lifestyle (p = .03) and caloric intake (.002) through obesity were found. These results suggest that life stress is related to atherosclerosis once paths of unhealthy coping behaviors are considered.

The role of lifestyle change in health promotion

Full Text Available We are experiencing a period where we are faced with rising healthcare costs, as well as an increased disease impact on the entire population of the country. Although the slogan “prevention is cheaper than cure” may seem old-fashioned, however, it is more true than ever. It is necessary to offer health education and also to promote health care in Romania, in accordance with the international standards, as adopted by the European Union. Health Promotion is the art and science of helping people change their lifestyle in order to achieve a state of optimal health, restoring the harmony at all levels of human existence. Promoting a lifestyle which given certain conditions maximizes health, welfare and human fulfilment represents a goal that does not belong exclusively to the health sector; all fields of activity, all those sectors that define the life of an individual or a community are essential parts of achieving a healthy lifestyle. Modern men adopt a lifestyle where sedentary life, overeating, smoking, erratic working hours and alcohol use are common behaviours. Therefore, they become vulnerable to a new class of diseases of multi-factorial aetiology where the lifestyle plays a prominent role. Although the lifestyle may be complex, it is still under personal control and lead by the ability to choose extensively, which can be of benefit to the person's life and health. Choices regarding health involve more than objective information. Health education should be an ongoing concern for health professionals and health educators, psychologists, sociologists, family, for those who through effective collaboration contribute to ensuring physical and mental health in the community, in the increasingly demanding conditions of the modern life, which raise difficult issues regarding human adaptability.

Carmen Pérez-Rodrigo

2017-06-01

Full Text Available Limited knowledge is available on lifestyle patterns in Spanish adults. We investigated dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, sleep time, and smoking in Spanish adults aged 18–64 years and their association with obesity. Analysis was based on a subsample (n = 1617 of the cross-sectional ANIBES study in Spain. We performed exploratory factor analysis and subsequent cluster analysis of dietary patterns, physical activity, sedentary behaviors, sleep time, and smoking. Logistic regression analysis was used to explore the association between the cluster solutions and obesity. Factor analysis identified four dietary patterns, “Traditional DP”, “Mediterranean DP”, “Snack DP” and “Dairy-sweet DP”. Dietary patterns, physical activity behaviors, sedentary behaviors, sleep time, and smoking in Spanish adults aggregated into three different clusters of lifestyle patterns: “Mixed diet-physically active-low sedentary lifestyle pattern”, “Not poor diet-low physical activity-low sedentary lifestyle pattern” and “Poor diet-low physical activity-sedentary lifestyle pattern”. A higher proportion of people aged 18–30 years was classified into the “Poor diet-low physical activity-sedentary lifestyle pattern”. The prevalence odds ratio for obesity in men in the “Mixed diet-physically active-low sedentary lifestyle pattern” was significantly lower compared to those in the “Poor diet-low physical activity-sedentary lifestyle pattern”. Those behavior patterns are helpful to identify specific issues in population subgroups and inform intervention strategies. The findings in this study underline the importance of designing and implementing interventions that address multiple health risk practices, considering lifestyle patterns and associated determinants.

Mortality in Japanese with life-styles similar to Seventh-Day Adventists: strategy for risk reduction by life-style modification.

Hirayama, T

1985-12-01

Using 16 years of follow-up results of a prospective cohort study for 122,261 men, 95% of the census population, aged 40 years and older in 29 Health Center Districts in Japan as subjects, we compared the age-standardized mortality rates for cancer of each site and other causes of death in Japanese with life-styles similar to those of Seventh-Day Adventists (SDA), i.e., no smoking, no drinking, no meat consumption daily and eating green and yellow vegetables daily, with those of Japanese with opposite life-styles. Compared with the latter Japanese, the risks were one-fifth or less in Japanese with SDA-like life-styles for cancers of the mouth, pharynx, esophagus, and lung, and subarachnoid hemorrhage. Risks were less than one-half for cancers of all sites, stomach, and liver, and for peptic ulcer and heart disease. As a single factor, the addition of daily smoking was observed to elevate the risk most strikingly in Japanese who followed SDA life patterns. Influences of further addition of habits of daily drinking of alcohol and dietary changes were significant for cancers of the esophagus, liver, and bladder and other selected diseases. Strategies for cancer prevention by means of life-style modification, e.g., increased consumption of green and yellow vegetables, were discussed.

Spectroscopy with cold and ultra-cold neutrons

Full Text Available We present two new types of spectroscopy methods for cold and ultra-cold neutrons. The first method, which uses the R×B drift effect to disperse charged particles in a uniformly curved magnetic field, allows to study neutron β-decay. We aim for a precision on the 10−4 level. The second method that we refer to as gravity resonance spectroscopy (GRS allows to test Newton’s gravity law at short distances. At the level of precision we are able to provide constraints on any possible gravity-like interaction. In particular, limits on dark energy chameleon fields are improved by several orders of magnitude.

Cold recovery during regasification of LNG part one: Cold utilization far from the regasification facility

La Rocca, Vincenzo

2010-01-01

The paper deals with cold recovery during LNG regasification. The applications analyzed pertain to the use in deep freezing agro food industry and in space air conditioning facilities in commercial sector (Supermarkets and Hypermarkets) of cold recovered from the regasification process. A modular LNG regasification unit is proposed having the regasification capacity of 2 BCM/year of gas and it is based on use of a Power Cycle working with Ethane, this unit allows operation of cold energy transfer, contained in LNG to be regasified, in a range of temperatures suitable for multipurpose use of cold, reducing regasification process irreversibility. Some electric energy is produced by the Power Cycle, but the purpose of the modular unit is to deliver cold suitable for industrial and commercial use in the proper temperature range utilizing Carbon dioxide as secondary fluid to transfer cold from regasification site to far end users. The subject is divided in two papers: this paper deals with facilities delivering cold released during LNG regasification and related pipeline facilities to transfer cold at far end users while the other paper pertains to analysis of end users applications. Results of a detailed thermodynamic and economic analysis demonstrate the suitability of the proposal.

Behavioral Lifestyle Intervention in the Treatment of Obesity

Shannon M. Looney

2013-01-01

Full Text Available This article provides an overview of research regarding adult behavioral lifestyle intervention for obesity treatment. We first describe two trials using a behavioral lifestyle intervention to induce weight loss in adults, the Diabetes Prevention Program (DPP and the Look AHEAD (Action for Health in Diabetes trial. We then review the three main components of a behavioral lifestyle intervention program: behavior therapy, an energy- and fat-restricted diet, and a moderate- to vigorous-intensity physical activity prescription. Research regarding the influence of dietary prescriptions focusing on macronutrient composition, meal replacements, and more novel dietary approaches (such as reducing dietary variety and energy density on weight loss is examined. Methods to assist with meeting physical activity goals, such as shortening exercise bouts, using a pedometer, and having access to exercise equipment within the home, are reviewed. To assist with improving weight loss outcomes, broadening activity goals to include resistance training and a reduction in sedentary behavior are considered. To increase the accessibility of behavioral lifestyle interventions to treat obesity in the broader population, translation of efficacious interventions such as the DPP, must be undertaken. Translational studies have successfully altered the DPP to reduce treatment intensity and/or used alternative modalities to implement the DPP in primary care, worksite, and church settings; several examples are provided. The use of new methodologies or technologies that provide individualized treatment and real-time feedback, and which may further enhance weight loss in behavioral lifestyle interventions, is also discussed.

Hornstein, Mark D

2016-12-01

Whereas much has been written about the prognostic factors associated with outcomes of in vitro fertilization (IVF) such as female age, diagnosis, and ovarian reserve, relatively little attention has been devoted to patient-oriented lifestyles that may influence IVF outcomes. Patients are particularly interested in this topic because many patients wish to partner with their physicians and want to know specific behaviors to improve their chances of IVF success. This brief review is not intended as an exhaustive literature search of all possible lifestyles that may influence assisted reproductive outcome nor is it intended to be a comprehensive review of individual topics. It does give, however, a brief overview of a number of areas in which patient-specific behaviors may influence outcomes in assisted reproduction. Specifically, this review will look at the effects of smoking, alcohol consumption, caffeine, diet, exercise, and exposure to the reproductive toxin bisphenol A on IVF outcomes. © The Author(s) 2016.

Studies on the impact of presurgery weight loss and lifestyle preparation on outcomes following bariatric surgery are needed. To evaluate whether a presurgery behavioral lifestyle intervention improves weight loss through a 24-month postsurgery period. Bariatric Center of Excellence at a large, urban medical center. Candidates for bariatric surgery were randomized to a 6-month behavioral lifestyle intervention or to 6 months of usual presurgical care. The lifestyle intervention consisted of 8 weekly face-to-face sessions, followed by 16 weeks of face-to-face and telephone sessions before surgery; the intervention also included 3 monthly telephone contacts after surgery. Assessments were conducted 6, 12, and 24 months after surgery. Participants who underwent surgery (n = 143) were 90.2% female and 86.7% White. Average age was 44.9 years, and average body mass index was 47.5 kg/m(2) at study enrollment. At follow-up, 131 (91.6%), 126 (88.1%), 117 (81.8%) patients participated in the 6-, 12-, and 24-month assessments, respectively. Percent weight loss from study enrollment to 6 and 12 months after surgery was comparable for both groups, but at 24 months after surgery, the lifestyle group had significantly smaller percent weight loss compared with the usual care group (26.5% versus 29.5%, respectively, P = .02). Presurgery lifestyle intervention did not improve weight loss at 24 months after surgery. The findings from this study raise questions about the utility and timing of adjunctive lifestyle interventions for bariatric surgery patients.

NKCP®, a natto-derived dietary food supplement whose main component is bacillopeptidase F, has antithrombotic, fibrinolytic, and blood pressure-lowering effects. We examined whether daily intake of NKCP® effectively improves subjective symptoms in patients with lifestyle diseases in this cross-over, double-blind study. Fermented soya extract with subtilisin NAT (nattokinase as the main component was used as an active placebo. A 4-week course of NKCP® significantly decreased the visual analog scale (VAS score for shoulder stiffness from 42.3 to 32.4 (P=0.009, the VAS score for low back pain from 25.5 to 18.8 (P=0.02, and the VAS score for coldness of the extremities from 33.1 to 25.7 (P=0.002. However, no significant difference was found in the VAS score for headache. After a 4-week course of active placebo, no significant changes in the VAS score were found for any symptoms. The significant improvement in the symptoms secondary to blood flow disturbance was caused by the improvement in blood flow by NKCP®. The use of dietary supplements based on the Japanese traditional food natto helps to relieve subjective symptoms for patients with lifestyle diseases receiving medical care.

Data from the National Health and Nutrition Examination Survey (NHANES) indicate 89% of Americans regularly consume caffeine, but these data do not include military personnel. This cross-sectional study examined caffeine use in Navy and Marine Corps personnel, including prevalence, amount of daily consumption, and factors associated with use. A random sample of Navy and Marine Corps personnel was contacted and asked to complete a detailed questionnaire describing their use of caffeine-containing substances, in addition to their demographic, military, and lifestyle characteristics. A total of 1708 service members (SMs) completed the questionnaire. Overall, 87% reported using caffeinated beverages ≥1 time/week, with caffeine users consuming a mean ± standard error of 226 ± 5 mg/day (242 ± 7 mg/day for men, 183 ± 8 mg/day for women). The most commonly consumed caffeinated beverages (% users) were coffee (65%), colas (54%), teas (40%), and energy drinks (28%). Multivariable logistic regression modeling indicated that characteristics independently associated with caffeine use (≥1 time/week) included older age, white race/ethnicity, higher alcohol consumption, and participating in less resistance training. Prevalence of caffeine use in these SMs was similar to that reported in civilian investigations, but daily consumption (mg/day) was higher. PMID:27735834

Lifestyle precision medicine: the next generation in type 2 diabetes prevention?

Science.gov (United States)

Mutie, Pascal M; Giordano, Giuseppe N; Franks, Paul W

2017-09-22

The driving force behind the current global type 2 diabetes epidemic is insulin resistance in overweight and obese individuals. Dietary factors, physical inactivity, and sedentary behaviors are the major modifiable risk factors for obesity. Nevertheless, many overweight/obese people do not develop diabetes and lifestyle interventions focused on weight loss and diabetes prevention are often ineffective. Traditionally, chronically elevated blood glucose concentrations have been the hallmark of diabetes; however, many individuals will either remain 'prediabetic' or regress to normoglycemia. Thus, there is a growing need for innovative strategies to tackle diabetes at scale. The emergence of biomarker technologies has allowed more targeted therapeutic strategies for diabetes prevention (precision medicine), though largely confined to pharmacotherapy. Unlike most drugs, lifestyle interventions often have systemic health-enhancing effects. Thus, the pursuance of lifestyle precision medicine in diabetes seems rational. Herein, we review the literature on lifestyle interventions and diabetes prevention, describing the biological systems that can be characterized at scale in human populations, linking them to lifestyle in diabetes, and consider some of the challenges impeding the clinical translation of lifestyle precision medicine.

Full Text Available Abstract Background Preventive services and health promotion in terms of lifestyle counselling provided through primary health care (PHC has the potential to reduce morbidity and mortality in the population. Health professionals in general are positive about and willing to develop a health-promoting and/or preventive role. A number of obstacles hindering PHC staff from addressing lifestyle issues have been identified, and one facilitator is the use of modern technology. When a computer-based tool for lifestyle intervention (CLT was introduced at a number of PHC units in Sweden, this provided an opportunity to study staff perspectives on the subject. The aim of this study was to explore PHC staff’s perceptions of handling lifestyle issues, including the consultation situation as well as the perceived usefulness of the CLT. Methods A qualitative study was conducted after the CLT had been in operation for 2 years. Six focus group interviews, one at each participating unit, including a total of 30 staff members with different professions participated. The interviews were designed to capture perceptions of addressing lifestyle issues, and of using the CLT. Interview data were analysed using manifest content analysis. Results Two main themes emerged from the interviews: a challenging task and confidence in handling lifestyle issues. The first theme covered the categories responsibilities and emotions, and the second theme covered the categories first contact, existing tools, and role of the CLT. Staff at the units showed commitment to health promotion/prevention, and saw that patients, caregivers, managers and politicians all have responsibilities regarding the issue. They expressed confidence in handling lifestyle-related conditions, but to a lesser extent had routines for general screening of lifestyle habits, and found addressing alcohol the most problematic issue. The CLT, intended to facilitate screening, was viewed as a complement, but was not

Cold water injection nozzles

Purpose: To inject cold water in a reactor without applying heat cycles to a reactor container and to the inner wall of a feedwater nozzle by securing a perforated plate at the outlet of the cold water injection nozzle. Constitution: A disc-like cap is secured to the final end of a return nozzle of a control rod drive. The cap prevents the flow of a high temperature water flowing downward in the reactor from entering into the nozzle. The cap is perforated with a plurality of bore holes for injecting cold water into the reactor. The cap is made to about 100 mm in thickness so that the cold water passing through the bore holes is heated by the heat conduction in the cap. Accordingly, the flow of high temperature water flowing downwardly in the reactor is inhibited by the cap from backward flowing into the nozzle. Moreover, the flow of the cold water in the nozzle is controlled and rectified when passed through the bore holes in the cap and then injected into the reactor. (Yoshino, Y.)

The infant-juvenile period is one of high vulnerability during the lifestyles chosen become determining factors for future health status. This study aimed to evaluate lifestyle, specifically eating habits and physical activity, in 5-15-year-olds in Spain and their health status (anthropometry). This cross-sectional population study with two time points (2006 and 2013) was conducted by compiling data from the Spanish National Health Survey. We used the minor survey, specifically the data from the Health Determinants module, which included 5-15-year-olds. Compiled information was obtained from parents or guardians. The overall overweight and obesity prevalence in Spain (2013) in 5- to 15-year-olds is 24.3%. A drop of 8.2% in meat consumption was found, while overall intake was high. Daily intake of plant-based food (fruit, vegetables, pulses) was low, especially vegetables (32.9%). Increased sedentary lifestyle was observed, probably because the use of communication technologies has increased in recent years (P<0.001). Moreover, watching TV rose to 19.3% for 1 hour/day watching TV on weekdays and to 23.5% at weekends. When comparing the two time points (2006 and 2013), we observed that lifestyle, eating habits and physical activity strongly associated with the Spanish infant-juvenile population's anthropometry. Mediterranean diet patterns seem to be abandoned and physical activity is practiced less, which will have a negative impact on future quality of life.

Lack of exercise and excessive food intake are known to be the important causes of nonalcoholic steatohepatitis (NASH). To elucidate the relationship between lifestyle and NASH, we surveyed exercise and dietary habits, comparing them among 171 biopsy-proven NASH patients, 29 nonalcoholic fatty liver (NAFL) patients and 49 normal subjects. Dietary habits including the duration of dinner time, amount of rice at dinner, and weekly frequencies of meat, fries, Chinese noodles, sweets, and instant food consumption were significantly different in male NASH patients compared to normal male subjects. In women, differences were seen in the amount of rice at dinner, frequency of eating out, and proclivity for sweets. In male NASH patients, the frequency of physical exercise was significantly lower. The lifestyle tendencies of NASH were almost similar to those of NAFL. In the comparison between obese NASH and non-obese NASH, no clear lifestyle differences were found. In conclusion, the most striking result of this survey was that the lifestyle of males contributed significantly to the development of NASH. These results point to treatment of NASH in males. In female NASH patients, lifestyle differences were minimal, and the effects of other factors such as genetic background will need to be investigated.

Recruiting isolated older adults to clinical trials is complex, time-consuming and difficult. Previous studies have suggested querying existing databases to identify appropriate potential participants. We aim to compare recruitment techniques (general practitioner (GP) mail-outs, community engagement and clinician referrals) used in three randomised controlled trial (RCT) studies assessing the feasibility or effectiveness of two preventative interventions in isolated older adults (the Lifestyle Matters and Putting Life In Years interventions). During the three studies (the Lifestyle Matters feasibility study, the Lifestyle Matters RCT, the Putting Life In Years RCT) data were collected about how participants were recruited. The number of letters sent by GP surgeries for each study was recorded. In the Lifestyle Matters RCT, we qualitatively interviewed participants and intervention facilitators at 6 months post randomisation to seek their thoughts on the recruitment process. Referrals were planned to be the main source of recruitment in the Lifestyle Matters feasibility study, but due to a lack of engagement from district nurses, community engagement was the main source of recruitment. District nurse referrals and community engagement were also utilised in the Lifestyle Matters and Putting Life In Years RCTs; both mechanisms yielded few participants. GP mail-outs were the main source of recruitment in both the RCTs, but of those contacted, recruiting yield was low (recruited. Participants recommended that direct contact with health professionals would be the most beneficial way to recruit. Recruitment to the Lifestyle Matters RCT did not mirror recruitment to the feasibility study of the same intervention. Direct district nurse referrals were not effective at recruiting participants. The majority of participants were recruited via GP mail-outs, which may have led to isolated individuals not being recruited to the trials. Further research is required into

Cold perception and gene expression differ in Olea europaea seed coat and embryo during drupe cold acclimation.

FAD2 and FAD7 desaturases are involved in cold acclimation of olive (Olea europaea) mesocarp. There is no research information available on cold acclimation of seeds during mesocarp cold acclimation or on differences in the cold response of the seed coat and embryo. How FAD2 and FAD7 affect seed coat and embryo cold responses is unknown. Osmotin positively affects cold acclimation in olive tree vegetative organs, but its role in the seeds requires investigation. OeFAD2.1, OeFAD2.2, OeFAD7 and Oeosmotin were investigated before and after mesocarp acclimation by transcriptomic, lipidomic and immunolabelling analyses, and cytosolic calcium concentration ([Ca(2+)](cyt)) signalling, F-actin changes and seed development were investigated by epifluorescence/histological analyses. Transient [Ca(2+)](cyt) rises and F-actin disassembly were found in cold-shocked protoplasts from the seed coat, but not from the embryo. The thickness of the outer endosperm cuticle increased during drupe exposure to lowering of temperature, whereas the embryo protoderm always lacked cuticle. OeFAD2 transcription increased in both the embryo and seed coat in the cold-acclimated drupe, but linoleic acid (i.e. the product of FAD2 activity) increased solely in the seed coat. Osmotin was immunodetected in the seed coat and endosperm of the cold-acclimated drupe, and not in the embryo. The results show cold responsiveness in the seed coat and cold tolerance in the embryo. We propose a role for the seed coat in maintaining embryo cold tolerance by increasing endosperm cutinization through FAD2 and osmotin activities. © 2012 The Authors.

COMBUSTION STAGE NUMERICAL ANALYSIS OF A MARINE ENGINE

Directory of Open Access Journals (Sweden)

DOREL DUMITRU VELCEA

2016-06-01

Full Text Available The primary goal of engine design is to maximize each efficiency factor, in order to extract the most power from the least amount of fuel. In terms of fluid dynamics, the volumetric and combustion efficiency are dependent on the fluid dynamics in the engine manifolds and cylinders. Cold flow analysis involves modeling the airflow in the transient engine cycle without reactions. The goal is to capture the mixture formation process by accurately accounting for the interaction of moving geometry with the fluid dynamics of the induction process. The changing characteristics of the air flow jet that tumbles into the cylinder with swirl via intake valves and the exhaust jet through the exhaust valves as they open and close can be determined, along with the turbulence production from swirl and tumble due to compression and squish. The target of this paper was to show how, by using the reverse engineering techniques, one may replicate and simulate the functioning conditions and parameters of an existing marine engine. The departing information were rather scarce in terms of real processes taking place in the combustion stage, but at the end we managed to have a full picture of the main parameters evolution during the combustion phase inside this existing marine engine

To evaluate the relationship between lifestyle habits and the components of metabolic syndrome (MS). Based on the routine health check-up system in a certain Center for Health Management of Shandong Province, a longitudinal surveillance health check-up cohort from 2005 to 2010 was set up. There were 13 225 urban workers in Jinan included in the analysis. The content of the survey included demographic information, medical history, lifestyle habits, body mass index (BMI) and the level of blood pressure, fasting blood-glucose, and blood lipid, etc. The distribution of BMI, blood pressure, fasting blood-glucose, blood lipid and lifestyle habits between MS patients and non-MS population was compared, latent variables were extracted by exploratory factor analysis to determine the structure model, and then a partial least squares path model was constructed between lifestyle habits and the components of MS. Participants'age was (46.62 ± 12.16) years old. The overall prevalence of the MS was 22.43% (2967/13 225), 26.49% (2535/9570) in males and 11.82% (432/3655) in females. The prevalence of the MS was statistically different between males and females (χ(2) = 327.08, P alcohol consumption has statistical difference (χ(2) = 374.22, P smoking status was statistically significant (χ(2) = 115.86, P smoking was 59.72% (1772/2967), 6.24% (185/2967), 34.04% (1010/2967) respectively, while in non-MS population was 70.03% (7184/10 258), 5.35% (549/10 258), 24.61% (2525/10 258) respectively. Both lifestyle habits and the components of MS were attributable to only one latent variable. After adjustment for age and gender, the path coefficient between the latent component of lifestyle habits and the latent component of MS was 0.22 with statistical significance (t = 6.46, P Unhealthy lifestyle habits are closely related to MS. Meat diet, excessive drinking and smoking are risk factors for MS.

Unhealthy lifestyles during childhood constitute a public health problem in Japan. However, current health education in Japan is ineffective in counteracting them. Previous studies contend that healthy lifestyles in children vary by academic grade and sex. This study examined changes throughout childhood suggests some intervention points for lifestyle education. The participants were 2833 elementary and junior high school students living in Japanese rural areas. Data on 26 variables assigned to 5 subfactors were collected. We estimated the composite score of each subfactor on the basis of item response theory. A 2-way ANOVA and a graph review were performed to explore the differences and changes by sex and grade. Most of the main effects for sex and grade were statistically significant. Lifestyle behaviors acquired early in elementary school were lost as students progressed to higher grades. The research indicated the following emphases: (1) Physical activity and leisure habits should be focused on girls and hygiene habits on boys; (2) Continuous education for a healthy lifestyle is essential to maintain good health among children; (3) Education for healthy lifestyle can be classified into 2 important stages such as for dietary and sleeping habits, education from the upper grades of elementary school is important, whereas for other routine activities, reeducation in junior high school is effective. © 2013, American School Health Association.

Our laboratory has been working toward increasing our understanding of the genetic control of cold hardiness in blueberry (Vaccinium section Cyanococcus) to ultimately use this information to develop more cold hardy cultivars for the industry. Here, we report using cDNA microarrays to monitor changes in gene expression at multiple times during cold acclimation under field and cold room conditions. Microarrays contained over 2,500 cDNA inserts, approximately half of which had been picked and single-pass sequenced from each of two cDNA libraries that were constructed from cold acclimated floral buds and non-acclimated floral buds of the fairly cold hardy cv. Bluecrop (Vaccinium corymbosum L.). Two biological samples were examined at each time point. Microarray data were analyzed statistically using t tests, ANOVA, clustering algorithms, and online analytical processing (OLAP). Interestingly, more transcripts were found to be upregulated under cold room conditions than under field conditions. Many of the genes induced only under cold room conditions could be divided into three major types: (1) genes associated with stress tolerance; (2) those that encode glycolytic and TCA cycle enzymes, and (3) those associated with protein synthesis machinery. A few of the genes induced only under field conditions appear to be related to light stress. Possible explanations for these differences are discussed in physiological context. Although many similarities exist in how plants respond during cold acclimation in the cold room and in the field environment, there are major differences suggesting caution should be taken in interpreting results based only on artificial, cold room conditions.

Lifestyle modification and progressive renal failure.

Ritz, Eberhard; Schwenger, Vedat

2005-08-01

There is increasing evidence that lifestyle factors impact on the risk of developing chronic kidney disease (CKD) and the risk of progression of CKD. Equally important is the consideration that patients with CKD are more likely to die from cardiovascular disease than to reach the stage of end-stage renal failure. It is advantageous that manoeuvres that interfere with progression at the same time also reduce the risk of cardiovascular events. Lifestyle factors that aggravate progression include, among others, smoking, obesity and dietary salt intake. Alcohol consumption, according to some preliminary information, has a bimodal relationship to cardiovascular risk and progression, with moderate consumption being protective.

Regardless of age, making healthy lifestyle choices is prudent. Despite that, individuals of all ages sometimes have difficulty choosing the healthy option. We argue that individuals' view of the future and position in the life span affects their current lifestyle choices. We capture the multidimensionality of future thinking by assessing 3 types of future perspective. Younger and older men and women (N = 127) reported global future time perspective, future health perspective, and perceived importance of future health-related events. They also rated their likelihood of making healthy lifestyle choices. As predicted, older participants indicated greater intention to make healthy choices in their current life than did younger participants. Compared to younger participants, older participants reported shorter global future time perspective and anticipated worse future health but perceived future health-related events as more important. Having a positive view of one's future health and seeing future health-related events as important were related to greater intention to make healthy lifestyle choices, but greater global future time perspective was not directly related to healthy choices. However, follow-up analyses suggested that greater global future time perspective indirectly affected healthy choices via a more positive view of future health. None of these relations were moderated by age. Individuals' perspective on the future is shown to be an important multidimensional construct affecting everyday healthy lifestyle choices for both younger and older adults. Implications for encouraging healthy choices across the adult life span are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

[Exercise for prevention of osteoporosis and other lifestyle-related diseases].

Suzuki, Takao

2011-05-01

The prevalence of lifestyle-related diseases including hypertension, dyslipidemia (hyperlipidemia) and diabetes increases with aging, and all these conditions are risk factors of arteriosclerotic diseases such as cerebrovascular event (stroke) and myocardial infarction. The term "metabolic domino" has been used to describe the collective concept of the development and progression of these lifestyle-related diseases, the sequence of events, and the progression process of complications. Like the first tile of a domino toppling game, undesirable lifestyle such as overeating and underexercising first triggers obesity, and is followed in succession by onset of an insulin resistance state (underlied by a genetic background indigenous to Japanese) , hypertension, hyperlipidemia, and further postprandial hyperglycemia (the pre-diabetic state) , the so-called metabolic syndrome, at around the same time. On the other hand, apart from the other lifestyle-related diseases, the prevalence of osteoporosis also increases rapidly accompanying aging. Osteoporosis is known to be strongly related to disorders due to the metabolic domino such as arteriosclerosis and vascular calcification, and a new disease category called "osteo-vascular interaction" has attracted attention recently. Regarding "osteo-vascular interaction" , a close relation between bone density loss or osteoporotic changes and vascular lesion-associated lifestyle-related diseases such as hypertension, dyslipidemia and diabetes has been reported. Therefore, as a common preventive factor for bone mass loss or osteoporosis and lifestyle-related diseases including hypertension, dyslipidemia and diabetes (osteo-vascular interaction) , exercise has been recognized anew as an important non-pharmaceutical therapy that should take top priority. This article overviews the evidence of exercise therapy for the prevention of osteoporosis and other lifestyle-related diseases, from the viewpoint of health promotion, especially of

2011-01-01

There is a lack of comparable data on physical activity, sedentary behavior, and dietary habits among Arab adolescents, which limits our understanding and interpretation of the relationship between obesity and lifestyle parameters. Therefore, we initiated the Arab Teens Lifestyle Study (ATLS). The ATLS is a multicenter collaborative project for assessing lifestyle habits of Arab adolescents. The objectives of the ATLS project were to investigate the prevalence rates for overweight and obesity, physical activity, sedentary activity and dietary habits among Arab adolescents, and to examine the interrelationships between these lifestyle variables. This paper reports on the objectives, design, methodology, and implications of the ATLS. The ATLS is a school-based cross-sectional study involving 9182 randomly selected secondary-school students (14-19 years) from major Arab cities, using a multistage stratified sampling technique. The participating Arab cities included Riyadh, Jeddah, and Al-Khobar (Saudi Arabia), Bahrain, Dubai (United Arab Emirates), Kuwait, Amman (Jordan), Mosel (Iraq), Muscat (Oman), Tunisia (Tunisia) and Kenitra (Morocco). Measured variables included anthropometric measurements, physical activity, sedentary behavior, sleep duration, and dietary habits. The ATLS project will provide a unique opportunity to collect and analyze important lifestyle information from Arab adolescents using standardized procedures. This is the first time a collaborative Arab project will simultaneously assess broad lifestyle variables in a large sample of adolescents from numerous urbanized Arab regions. This joint research project will supply us with comprehensive and recent data on physical activity/inactivity and eating habits of Arab adolescents relative to obesity. Such invaluable lifestyle-related data are crucial for developing public health policies and regional strategies for health promotion and disease prevention.

Effects of cold temperatures on the excitability of rat trigeminal ganglion neurons that are not for cold sensing.

Aside from a small population of primary afferent neurons for sensing cold, which generate sensations of innocuous and noxious cold, it is generally believed that cold temperatures suppress the excitability of primary afferent neurons not responsible for cold sensing. These not-for-cold-sensing neurons include the majority of non-nociceptive and nociceptive afferent neurons. In this study we have found that the not-for-cold-sensing neurons of rat trigeminal ganglia (TG) change their excitability in several ways at cooling temperatures. In nearly 70% of not-for-cold-sensing TG neurons, a cooling temperature of 15°C increases their membrane excitability. We regard these neurons as cold-active neurons. For the remaining 30% of not-for-cold-sensing TG neurons, the cooling temperature of 15°C either has no effect (cold-ineffective neurons) or suppress their membrane excitability (cold-suppressive neurons). For cold-active neurons, the cold temperature of 15°C increases their excitability as is evidenced by increases in action potential (AP) firing numbers and/or the reduction in AP rheobase when these neurons are depolarized electrically. The cold temperature of 15°C significantly inhibits M-currents and increases membrane input resistance of cold-active neurons. Retigabine, an M-current activator, abolishes the effect of cold temperatures on AP firing, but not the effect of cold temperature on AP rheobase levels. The inhibition of M-currents and the increases of membrane input resistance are likely two mechanisms by which cooling temperatures increase the excitability of not-for-cold-sensing TG neurons.

The number of persons suffering from type 2 diabetes mellitus continues to rise worldwide and causes significant morbidity and mortality, especially in the developing world. Behaviour change and adoption of healthy lifestyle habits help to prevent or slow down the complications of type 2 diabetes mellitus. However, the knowledge and practice of healthy lifestyles in many diabetic patients have been inadequate. This study sought to establish the knowledge, attitude and practice regarding lifestyle modification amongst type 2 diabetic patients. The diabetic clinic of Mamelodi hospital, Pretoria, Gauteng Province, South Africa. A cross-sectional study was done using a structured questionnaire amongst 217 type 2 diabetic patients seen at the diabetic clinic of Mamelodi hospital. Baseline characteristics of the participants were obtained and their knowledge, attitude and practice regarding lifestyle modification were assessed. Of the 217 participants, 154 (71%) were obese and 15 (7%) were morbidly obese. The majority of respondents (92.2%) had poor knowledge of the benefits of exercise, weight loss and a healthy diet. What is interesting is that the majority (97.7%) demonstrated bad practices in relation to lifestyle modifications, although over four-fifths (84.3%) had a positive attitude toward healthy lifestyle modifications. Despite the positive attitudes of respondents toward healthy lifestyle modifications, the knowledge and practice regarding lifestyle modifications amongst type 2 diabetes mellitus participants seen at Mamelodi hospital were generally poor.

Lifestyle behaviors such as reducing weight if overweight or obese, reducing salt intake, exercising, reducing alcohol intake, quitting smoking, and eating a healthy diet are related to the prevention and control of chronic diseases. However the amount of lifestyle advice provided by clinicians has been declining over the last decade. In 2002, a telephone survey was conducted to assess the quality of preventive care offered by health care providers. The study was a cross-sectional observational study of a randomly selected sample of 516 diverse individuals in Durham County, North Carolina. Information regarding age, sex, race, education, health conditions, and self-reported receipt of lifestyle advice was examined in the study. The odds of receiving advice to engage in preventive lifestyle behaviors were significantly higher for those with a pre-existing diagnosis of diabetes or hypertension and for participants reporting poor health status. For example, the odds of receiving advice to control or lose weight was 8.32 (95% CI, 2.65, 26.75) among individuals reporting a diagnosis of diabetes. Similarly, the odds of reporting "receiving advice to reduce salt intake" was 6.97 (95% CI, 3.74, 13.00) among subjects reporting a diagnosis of hypertension. The results are from a cross-sectional study of a sample of individuals in only one county. Additionally, the results are based on patient self-reported information, which could be subject to recall and social desirability bias. Patients with identified health problems were more likely than others to report being advised to adopt healthy lifestyle recommendations. Future research should examine methods to encourage health care providers to offer lifestyle advice to those without pre-existing illness.

It is well-documented that severe cold stress impairs exercise performance. Repeated immersion in cold water induces an insulative type of cold acclimation, wherein enhanced vasoconstriction leads to greater body heat retention, which may attenuate cold-induced exercise impairments. The purpose of this study, therefore, was to investigate changes in exercise performance during a 7-day insulative type of cold acclimation. Twelve healthy participants consisting of eight males and four females (mean ± SD age: 25.6 ± 5.2 years, height: 174.0 ± 8.9 cm, weight: 75.6 ± 13.1 kg) performed a 20 min self-paced cycling test in 23 °C, 40% humidity without prior cold exposure. Twenty-four hours later they began a 7-day cold acclimation protocol (daily 90 min immersion in 10 °C water). On days one, four, and seven of cold acclimation, participants completed the same cycling test. Measurements of work completed, core and skin temperatures, heart rate, skin blood flow, perceived exertion, and thermal sensation were measured during each cycling test. Successful insulative cold acclimation was observed. Work produced during the baseline cycling test (220 ± 70 kJ) was greater (p immersions (195 ± 58, 197 ± 60, and 194 ± 62 kJ) despite similar ratings of perceived exertion during each test, suggesting that cold exposure impaired cycling performance. This impairment, however, was not attenuated over the cold acclimation period. Results suggest that insulative cold acclimation does not attenuate impairments in exercise performance that were observed following acute cold water immersion.

Currently, cold temperatures are one of the main factors threatening rapeseed production worldwide; thus, it is imperative to identify cold-resistant germplasm and to cultivate cold-resistant rapeseed varieties. In this study, the cold resistance of four Brassica rapa varieties was analyzed. The cold resistance of Longyou6 and Longyou7 was better than that of Tianyou2 and Tianyou4. Thus, an F 2 population derived from Longyou6 and Tianyou4 was used to study the correlation of cold resistance and physiological indexes. Our results showed that the degree of frost damage was related to the relative conductivity and MDA content (r1 = 0.558 and r2 = 0.447, respectively). In order to identify the markers related to cold resistance, 504 pairs of SSR (simple sequence repeats) primers were used to screen the two parents and F 2 population. Four and five SSR markers had highly significant positive correlation to relative conductivity and MDA, respectively. In addition, three of these SSR markers had a highly significant positive correlation to both of these two indexes. These three SSR markers were subsequently confirmed to be used to distinguish between cold-resistant and non-cold-resistant varieties. The results of this study will lay a solid foundation for the mapping of cold-resistant genes and molecular markers assisted selection for the cold-resistance.

Lifestyle modification based on behavior therapy is the most important and effective strategy to manage the metabolic syndrome. Modern lifestyle modification therapy combines specific recommendations on diet and exercise with behavioral and cognitive strategies. The intervention may be delivered face-to-face or in groups, or in groups combined with individual sessions. The main challenge of treatment is helping patients maintain healthy behavior changes in the long term. In the last few years, several strategies have been evaluated to improve the long-term effect of lifestyle modification. Promising results have been achieved by combining lifestyle modification with pharmacotherapy, using meals replacement, setting higher physical activity goals, and long-term care. The key role of cognitive processes in the success/failure of weight loss and maintenance suggests that new cognitive procedures and strategies should be included in the traditional lifestyle modification interventions, in order to help patients build a mind-set favoring long-term lifestyle changes. These new strategies raise optimistic expectations for an effective treatment of metabolic syndrome with lifestyle modifications, provided public health programs to change the environment where patients live support them.

2012-04-01

Full Text Available Atmospheric water soluble organic nitrogen (WSON is a subset of the complex organic matter in aerosols and rainwater, which impacts cloud condensation processes and aerosol chemical and optical properties and may play a significant role in the biogeochemical cycle of N. However, its sources, composition, connections to inorganic N, and variability are largely unknown. Rainwater samples were collected on the island of Bermuda (32.27° N, 64.87° W, which experiences both anthropogenic and marine influenced air masses. Samples were analyzed by ultra-high resolution electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry to chemically characterize the WSON. Elemental compositions of 2281 N containing compounds were determined over the mass range m/z⁺ 50 to 500. The five compound classes with the largest number of elemental formulas identified, in order from the highest number of formulas to the lowest, contained carbon, hydrogen, oxygen, and nitrogen (CHON+, CHON compounds that contained sulfur (CHONS+, CHON compounds that contained phosphorus (CHONP+, CHON compounds that contained both sulfur and phosphorus (CHONSP+, and compounds that contained only carbon, hydrogen, and nitrogen (CHN+. Compared to rainwater collected in the continental USA, average O:C ratios of all N containing compound classes were lower in the marine samples whereas double bond equivalent values were higher, suggesting a reduced role of secondary formation mechanisms. Despite their prevalence in continental rainwater, no organonitrates or nitrooxy-organosulfates were detected, but there was an increased presence of organic S and organic P containing compounds in the marine rainwater. Cluster analysis showed a clear chemical distinction between samples collected during the cold season (October to March which have anthropogenic air mass origins and samples collected during the warm season (April to September with remote

Cold moderators at ORNL

International Nuclear Information System (INIS)

Lucas, A. T.

1997-09-01

The Advanced Neutron Source (ANS) cold moderators were not an 'Oak Ridge first', but would have been the largest both physically and in terms of cold neutron flux. Two cold moderators were planned each 410 mm in diameter and containing about 30L of liquid deuterium. They were to be completely independent of each other. A modular system design was used to provide greater reliability and serviceability. When the ANS was terminated, upgrading of the resident High Flux Isotope Reactor (HFIR) was examined and an initial study was made into the feasibility of adding a cold source. Because the ANS design was modular, it was possible to use many identical design features. Sub-cooled liquid at 4 bar abs was initially chosen for the HFIR design concept, but this was subsequently changed to 15 bar abs to operate above the critical pressure. As in the ANS, the hydrogen will operate at a constant pressure throughout the temperature range and a completely closed loop with secondary containment was adopted. The heat load of 2 kW made the heat flux comparable with that of the ANS. Subsequent studies into the construction of cryogenic moderators for the proposed new Synchrotron Neutron source indicated that again many of the same design concepts could be used. By connecting the two cold sources together in series, the total heat load of 2 kW is very close to that of the HFIR allowing a very similar supercritical hydrogen system to be configured. The two hydrogen moderators of the SNS provide a comparable heat load to the HFIR moderator. It is subsequently planned to connect the two in series and operate from a single cold loop system, once again using supercritical hydrogen. The spallation source also provided an opportunity to re-examine a cold pellet solid methane moderator operating at 20K.

Background: GPs have a mandate from society to facilitate their patients to adopt a healthy lifestyle to reduce the burden of non-communicable diseases. GPs consider lifestyle counselling as an important but challenging task, but often choose not to follow clinical guidelines in lifestyle counselling. Power in doctor-patient relationships is asymmetrically distributed. In lifestyle counselling the GP may use power to make the patient change an unhealthy lifestyle. Doctors have ...

Physicians report poor training and lack of confidence in counseling patients on lifestyle changes. To evaluate a new curriculum and rotation in lifestyle medicine for preventive medicine residents. Training included didactics (six sessions/year), distance learning, educational conferences, and newly developed lifestyle medicine rotations at the Institute of Lifestyle Medicine, the Yale-Griffin Prevention Research Center, and the Integrative Medicine Center. We used a number of tools to assess residents' progress including Objective Structured Clinical Examinations (OSCEs), self-assessments, and logs of personal health habits. A total of 20 residents participated in the lifestyle medicine training between 2010 and 2013. There was a 15% increase in residents' discussions of lifestyle issues with their patients based on their baseline and follow-up surveys. The performance of preventive medicine residents on OSCEs increased each year they were in the program (average OSCE score: PGY1 73%, PGY2 83%, PGY3 87%, and PGY4 91%, p=0.01). Our internal medicine and preliminary residents served as a control, since they did participate in didactics but not in lifestyle medicine rotations. Internal medicine and preliminary residents who completed the same OSCEs had a slightly lower average score (76%) compared with plural for resident, preventive medicine residents (80%). However, this difference did not reach statistical significance (p=0.11). Incorporating the lifestyle medicine curriculum is feasible for preventive medicine training allowing residents to improve their health behavior change discussions with patients as well as their own personal health habits.

On cold spots in tumor subvolumes

International Nuclear Information System (INIS)

Tome, Wolfgang A.; Fowler, Jack F.

2002-01-01

Losses in tumor control are estimated for cold spots of various 'sizes' and degrees of 'cold dose'. This question is important in the context of intensity modulated radiotherapy where differential dose-volume histograms (DVHs) for targets that abut a critical structure often exhibit a cold dose tail. This can be detrimental to tumor control probability (TCP) for fractions of cold volumes even as small as 1%, if the cold dose is lower than the prescribed dose by substantially more than 10%. The Niemierko-Goitein linear-quadratic algorithm with γ 50 slope 1-3 was used to study the effect of cold spots of various degrees (dose deficit below the prescription dose) and size (fractional volume of the cold dose). A two-bin model DVH has been constructed in which the cold dose bin is allowed to vary from a dose deficit of 1%-50% below prescription dose and to have volumes varying from 1% to 90%. In order to study and quantify the effect of a small volume of cold dose on TCP and effective uniform dose (EUD), a four-bin DVH model has been constructed in which the lowest dose bin, which has a fractional volume of 1%, is allowed to vary from 10% to 45% dose deficit below prescription dose. The highest dose bin represents a simultaneous boost. For fixed size of the cold spot the calculated values of TCP decreased rapidly with increasing degrees of cold dose for any size of the cold spot, even as small as 1% fractional volume. For the four-subvolume model, in which the highest dose bin has a fractional volume of 80% and is set at a boost dose of 10% above prescription dose, it is found that the loss in TCP and EUD is moderate as long as the cold 1% subvolume has a deficit less than approximately 20%. However, as the dose deficit in the 1% subvolume bin increases further it drives TCP and EUD rapidly down and can lead to a serious loss in TCP and EUD. Since a dose deficit to a 1% volume of the target that is larger than 20% of the prescription dose may lead to serious loss of

A transcription factor for cold sensation!

2005-03-01

Full Text Available Abstract The ability to feel hot and cold is critical for animals and human beings to survive in the natural environment. Unlike other sensations, the physiology of cold sensation is mostly unknown. In the present study, we use genetically modified mice that do not express nerve growth factor-inducible B (NGFIB to investigate the possible role of NGFIB in cold sensation. We found that genetic deletion of NGFIB selectively affected behavioral responses to cold stimuli while behavioral responses to noxious heat or mechanical stimuli were normal. Furthermore, behavioral responses remained reduced or blocked in NGFIB knockout mice even after repetitive application of cold stimuli. Our results provide strong evidence that the first transcription factor NGFIB determines the ability of animals to respond to cold stimulation.

Full Text Available Based upon long-term observations (1993 - 2010 of satellite-derived winter sea surface temperature (SST data, an exceptional cold-water intrusion into the southern Taiwan Strait (TS was noted in February 2008. In the winter of 2008, La Niña caused a strong and continuous northeasterly wind that drove the cold ocean current, the China Coastal Current, more southward to penetrate the southern TS north of the Chang-Yuen Ridge. A portion of this current turned eastward to the south of Penghu Islands (PHI. The low-SST event significantly impeded local marine aquaculture and wild fish, causing the death of more than 73 tons of fish around PHI. Comparing variations of the first quarterly catches in 2008 with the long-term averages from 1993 to 2010 (excluding 2008, we noted a 50 to 80% decrease in catches from pole-and-line, long-line, and gill-net fishery. Non-migratory species dominated the composition of the catches. We also noted a greater than 230% increase in the catches from set-net fishery, with the majority being migratory species. These results illustrate the positive and negative effects of cold-water intrusion on several fish communities and species.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder with diverse reproductive and metabolic features. It is underpinned by insulin resistance that is exacerbated by obesity. Lifestyle modification is the first line treatment in PCOS, but it is associated with low adherence and sustainability. In small studies, metformin improves outcomes such as hyperinsulinaemia, ovulation and menstrual cyclicity. We conducted a systematic review and meta-analysis to compare the effect of lifestyle modification + metformin with lifestyle modification ± placebo, and of metformin alone with lifestyle modification ± placebo in PCOS on anthropometric, metabolic, reproductive and psychological outcomes. Databases including MEDLINE, EMBASE, Pubmed, Scopus, Cochrane, PsycINFO, CINAHL, Clinical Trials registry and ANZCTR were searched for RCTs conducted on humans and published in English up to August 2014. Inclusion criteria were diagnosis of PCOS based on Rotterdam criteria (inclusive of National Institutes of Health criteria) at any age and with any BMI. Interventions of interest included lifestyle + metformin (with any dose and any duration) or metformin alone compared with lifestyle ± placebo. Of 2372 identified studies, 12 RCTs were included for analysis comprising 608 women with PCOS. Lifestyle + metformin were associated with lower BMI (mean difference (MD) -0.73 kg/m(2), 95% confidence intervals (CI) -1.14, -0.32, P = 0.0005) and subcutaneous adipose tissue (MD -92.49 cm(2), 95% CI -164.14, -20.84, P = 0.01) and increased number of menstrual cycles (MD 1.06, 95% CI 0.30, 1.82, P = 0.006) after 6 months compared with lifestyle ± placebo. There were no differences in other anthropometric, metabolic (surrogate markers of insulin resistance, fasting and area under the curve glucose, lipids and blood pressure), reproductive (clinical and biochemical hyperandrogenism), and psychological (quality of life) outcomes after 6 months between lifestyle + metformin compared with

Modern lifestyle modification therapy combines specific recommendations on diet and exercise with behavioral and cognitive strategies. The intervention may be delivered face-to-face or in groups, or in groups combined with individual sessions. The main challenge of treatment is helping patients maintain healthy behavior changes in the long term. In the last few years, several strategies have been evaluated to improve the long-term effect of lifestyle modification. Promising results have been achieved by combining lifestyle modification with pharmacotherapy, using meals replacement, setting higher physical activity goals, and long-term care. The key role of cognitive processes in the success/failure of weight loss and maintenance suggests that new cognitive procedures and strategies should be included in the traditional lifestyle modification interventions, in order to help patients build a mind-set favoring long-term lifestyle changes. These new strategies raise optimistic expectations for an effective treatment of metabolic syndrome with lifestyle modifications, provided public health programs to change the environment where patients live support them.Keywords: metabolic syndrome, obesity, lifestyle modification, cognitive behavior therapy

The high traffic accident risk among young drivers is a well-known and well-documented fact in most countries. Lifestyle has proven to affect driving behavior as well as accident risk. This study covers the lifestyle component of the problems related to young male Kuwaiti drivers' accident risk. The purpose of the study is to measure the relationship between lifestyle and accident risk. Lifestyle is measured through a questionnaire, where 302 male Kuwaiti drivers (mean age=28 years; range 25-35 years) answer 39 questions related to behavioral and social factors, road conditions, police enforcement, and life satisfaction. They also report their involvement in accidents and traffic violations. The questionnaire's validity and reliability (Cronbach's alpha=0.7) were achieved. Principal component analysis reduced the 39 items on the questionnaire to 5 factors. Inadequate police enforcement is strongly correlated (r=0.862) to accident risk and traffic violations and is thus considered the best predictor of traffic accidents in Kuwait. As driving-related incidents (on-the-job and off-the-job) are a significant source of fatalities and lost-work-days, the study points to the importance of considering cultural factors in the design of comprehensive safety programs for industry. 2010.

Global patterns of extinction risk in marine and non-marine systems.

Webb, Thomas J; Mindel, Beth L

2015-02-16

Despite increasing concern over the effects of human activities on marine ecosystems, extinction in the sea remains scarce: 19-24 out of a total of >850 recorded extinctions implies a 9-fold lower marine extinction rate compared to non-marine systems. The extent of threats faced by marine systems, and their resilience to them, receive considerable attention, but the detectability of marine extinctions is less well understood. Before its extinction or threat status is recorded, a species must be both taxonomically described and then formally assessed; lower rates of either process for marine species could thus impact patterns of extinction risk, especially as species missing from taxonomic inventories may often be more vulnerable than described species. We combine data on taxonomic description with conservation assessments from the International Union for Conservation of Nature (IUCN) to test these possibilities across almost all marine and non-marine eukaryotes. We find that the 9-fold lower rate of recorded extinctions and 4-fold lower rate of ongoing extinction risk across marine species can be explained in part by differences in the proportion of species assessed by the IUCN (3% cf. 4% of non-marine species). Furthermore, once taxonomic knowledge and conservation assessments pass a threshold level, differences in extinction risk between marine and non-marine groups largely disappear. Indeed, across the best-studied taxonomic groups, there is no difference between marine and non-marine systems, with on average between 20% and 25% of species being threatened with extinction, regardless of realm.

Metagenomic Classification and Characterization Marine Actinobacteria from the Gulf of Maine without Representative Genomes

Science.gov (United States)

Sachdeva, R.; Heidelberg, J.

2012-12-01

Actinobacteria represent one of the largest and most diverse bacterial phyla and unlike most marine prokaryotes are gram-positive. This phylum encompasses a broad range of physiologies, morphologies, and metabolic properties with a broad array of lifestyles. The marine actinobacterial assemblage is dominated by the orders Actinomycetales and Acidimicrobiales (also known as the marine Actinobacteria clade). The Acidimicrobiales bacteria typically outnumber the Actinomycetales bacteria and are mostly represented by the OCS155 group. Although bacteria of the order Acidimicrobiales make up ~7.6% of the 16S matches from the Global Ocean Survey shotgun metagenomic libraries; very little is known about their potential function and role in biogeochemical cycling. Samples were collected from surface seawater samples in the Gulf of Maine (GOM) from the summer and winter of 2006. Sanger sequences were generated from the 0.1-0.8 μm fractions using paired-end medium insert shotgun libraries. The resulting 2.2 Gb were assembled using the Celera Assembler package into 280 Mb of non-redundant scaffolds. Putative actinobacterial assemblies were identified using (1) ribosomal RNA genes (16S and 23S), (2) phylogenetically informative non-ribosomal core genes thought to be resistant to horizontal gene transfer (e.g. RecA and RpoB) and (3) compositional binning using oligonucleotide frequency pattern based hierarchical clustering. Binning resulted in 3.6 Mb (4.2X coverage) of actinobacterial scaffolds that were comprised of 15.1 Mb of unassembled reads. Putative actinobacterial assemblies included both summer and winter reads demonstrating that the Actinobacteria are abundant year round. Classification reveals that all of the sampled Actinobacteria are from the orders Acidimicrobiales and Actinomycetales and are similar to those found in the global ocean. The GOM Actinobacteria show a broad range of G+C % content (32-66%) indicating a high level of genomic diversity. Those assemblies

2013-09-01

Full Text Available Biodiesel produced from vegetable oils, animal fats and algae oil is a renewable, environmentally friendly and clean alternative fuel that reduces pollutants and greenhouse gas emissions in marine applications. This study investigates the influence of biodiesel blend on the characteristics of residual and distillate marine fuels. Adequate correlation equations are applied to calculate the fuel properties of the blended marine fuels with biodiesel. Residual marine fuel RMA has inferior fuel characteristics compared with distillate marine fuel DMA and biodiesel. The flash point of marine fuel RMA could be increased by 20% if blended with 20 vol% biodiesel. The sulfur content of residual marine fuel could meet the requirement of the 2008 MARPOL Annex VI Amendment by blending it with 23.0 vol% biodiesel. In addition, the kinematic viscosity of residual marine fuel could be reduced by 12.9% and the carbon residue by 23.6% if 20 vol% and 25 vol% biodiesel are used, respectively. Residual marine fuel blended with 20 vol% biodiesel decreases its lower heating value by 1.9%. Moreover, the fuel properties of residual marine fuel are found to improve more significantly with biodiesel blending than those of distillate marine fuel.

Various behaviors are considered health enhancing. Nevertheless, according to the current scientific literature, four health behaviors are considered particularly risky in view of their association with a group of chronic diseases: 1) smoking; 2) excessive alcohol consumption; 3) poor diet; and 4) lack of physical activity. Theoretically, it should be possible to make improvements to one's health by maximizing the number of healthy behaviors and minimizing the unhealthy ones. However, in reality, the different behaviors interconnect to create more complex lifestyles. Therefore, the objective of this paper is to present the construction of a lifestyle indicator based on health behaviors selected in the ELSA-Brazil study. This indicator revealed two lifestyles: less healthy and healthier lifestyles. The model proved adequate and was confirmed using latent class analysis (LCA). Agreement was 83.2 between the indicator and the LCA results, with a kappa coefficient of 0.65. Women were more likely to have a healthier lifestyle than men, reinforcing the scientific consistency of the indicator, since this finding is in agreement with data from the scientific literature. The indicator created to define lifestyle was found to have scientific consistency and validity; therefore, its use can be recommended for future population-based studies concerning the promotion of health and healthy lifestyles.

Full Text Available The purpose of this study was to demonstrate the impact of certain lifestyles in our daily lives, and to reference some of them, among which are a sedentary lifestyle, diet, physical activity, social and family support, and the impact they have on people’ quality of life. It is clear that as a human beings, the developments in everyday life are addressed by duties and rights that affect our way of living, hence all individuals should enjoy the right to a better quality of life; to achieve this, it is necessary to maintain healthy lifestyle habits that create mechanisms to protect people against the development of chronic degenerative diseases. Historically it has been shown that people who have unhealthy life habits develop over time no only hypokinetic diseases, but also neurological ones such as Alzheimer's and Parkinson's. Under this scenario this paper is intended to present clear and concise information about what lifestyles represent to people and their importance as a right for everyone who decides to adapt them to their daily lives.

Dietary and lifestyle behaviours among adolescents are risk factors for several chronic diseases in adulthood. To examine the differences in dietary habits and lifestyle between male and female adolescents in Syria. A cross-sectional multi-stage stratified sampling study was carried out on adolescents, 15-18-years-old, in Damascus, Syria. The total sample selected was 365 (178 males and 187 females). Data were collected with a pretested questionnaire. There were significant differences between males and females in the frequency of intake of vegetables, milk and dairy products, red meat, sugary beverages and fast foods. Females were more likely to skip breakfast than males (52.4% vs. 43%), but the difference was not statistically significant. Males were significantly more likely to consume larger portions of fast foods and soft drinks. Significant differences were found between genders in eating while watching television, hours using Internet, practicing physical activity and emotional eating. A significant variation between male and female Syrian adolescents in their food habits and lifestyle was observed. Interventions should consider the gender differences to promote a healthy lifestyle for schoolchildren in Syria.

People with multiple unhealthy lifestyles are less likely to consult primary healthcare.

Behavioural interventions are often implemented within primary healthcare settings to prevent type 2 diabetes and other lifestyle-related diseases. Although smoking, alcohol consumption, physical inactivity and poor diet are associated with poorer health that may lead a person to consult a general practitioner (GP), previous work has shown that unhealthy lifestyles cluster among low socioeconomic groups who are less likely to seek primary healthcare. Therefore, it is uncertain whether behavioural interventions in primary healthcare are reaching those in most need. This study investigated patterns of GP consultations in relation to the clustering of unhealthy lifestyles among a large sample of adults aged 45 years and older in New South Wales, Australia. A total of 267,153 adults participated in the 45 and Up Study between 2006 and 2009, comprising 10% of the equivalent demographic in the state of New South Wales, Australia (response rate: 18%). All consultations with GPs within 6 months prior and post survey completion were identified (with many respondents attending multiple GPs) via linkage to Medicare Australia data. An index of unhealthy lifestyles was constructed from self-report data on adherence to published guidelines on smoking, alcohol consumption, diet and physical activity. Logistic and zero-truncated negative binomial regression models were used to analyse: (i) whether or not a person had at least one GP consultation within the study period; (ii) the count of GP consultations attended by each participant who visited a GP at least once. Analyses were adjusted for measures of health status, socioeconomic circumstances and other confounders. After adjustment, participants scoring 7 unhealthy lifestyles were 24% more likely than persons scoring 0 unhealthy lifestyles not to have attended any GP consultation in the 12-month time period. Among those who attended at least one consultation, those with 7 unhealthy lifestyles reported 7% fewer consultations than

2006-05-01

Several studies have shown that risky driving is especially prevalent among young drivers and recent research has pointed out that driving in adolescence should be investigated in the more general context of adolescent development. The first aim of this contribution was to analyze involvement in risky driving in a normative sample of 645 Italian adolescents, boys and girls, aged 14-17, through a self-report questionnaire. A second aim was to evaluate the association between risky driving and lifestyle, defined as involvement in other health risk behaviors and leisure activities. The main results showed that many adolescents drove cars and motorcycles without the required driving license and the most frequent offences were speeding and failure to maintain a safe braking distance. Gender and age differences were also investigated. Results concerning the association between risky driving and lifestyle showed that risky driving was not an isolated behavior. Boys who displayed risky driving practices were more likely to adopt a lifestyle characterized by high involvement in antisocial behaviors, tobacco smoking, comfort eating and time spent in non-organized activities with friends. Girls involved in risky driving were more likely to be involved in other risk-taking behaviors, antisocial behaviors and drug use.

Full Text Available In our fast paced world, using technology allows us to connect with people and assist them in developing healthier lifestyles within their time limits due to families, work, and other responsibilities. The goal of our project was the development of online, technology-based, nutrition, health, and fitness education challenges using social media as a means of helping consumers develop healthy lifestyle changes. Participants completed preassessments and postassessments to determine overall program impact and to self-report perceptions of knowledge gained and practice/behavior change. Results from the challenges indicated participants gained knowledge on nutrition, health and fitness topics while making strides towards lifestyle changes and adoption of healthy habits. Results revealed healthier eating habits were developed and physical activity was increased with many participants losing weight. Ease of participating was the most reported reason for participating in the challenges. To determine “best practice,” varying lengths of time for the challenges from four, seven, and thirteen weeks allowed the educators to derive implications for future programming, including branding, length of the challenge, frequency, and participant behavior change. To remain relevant and reach a greater diversity of populations, educators need to continue to explore and utilize various social media tools.

The Ocean in Depth - Ideas for Using Marine Technology in Science Communication

By deploying camera and video systems on remotely operated diving vehicles (ROVs), new and fascinating insights concerning the functioning of deep ocean ecosystems like cold-water coral reef communities can be gained. Moreover, mapping hot vents at mid-ocean ridge locations, and exploring asphalt and mud volcanoes in the Gulf of Mexico and the Mediterranean Sea with the aid of video camera systems have illustrated the scientific value of state-of-the-art diving tools. In principle, the deployment of sophisticated marine technology on seagoing expeditions and their results - video tapes and photographs of fascinating submarine environments, publication of new scientific findings - offer unique opportunities for communicating marine sciences. Experience shows that an interest in marine technology can easily be stirred in laypersons if the deployment of underwater vehicles such as ROVs during seagoing expeditions can be presented using catchwords like "discovery", "new frontier", groundbreaking mission", etc. On the other hand, however, a number of restrictions and challenges have to be kept in mind. Communicating marine science in general, and the achievements of marine technology in particular, can only be successful with the application of a well-defined target-audience concept. While national and international TV stations and production companies are very much interested in using high quality underwater video footage, the involvement of journalists and camera teams in seagoing expeditions entails a number a challenges: berths onboard research vessels are limited; safety aspects have to be considered; copyright and utilisation questions of digitalized video and photo material has to be handled with special care. To cite one example: on-board video material produced by professional TV teams cannot be used by the research institute that operated the expedition. This presentation aims at (1)informing members of the scientific community about new opportunities related

Repeated deep dives are highly pro-oxidative events for air-breathing aquatic foragers such as penguins. At fledging, the transition from a strictly terrestrial to a marine lifestyle may therefore trigger a complex set of anti-oxidant responses to prevent chronic oxidative stress in immature penguins but these processes are still undefined. By combining in vivo and in vitro approaches with transcriptome analysis, we investigated the adaptive responses of sea-acclimatized (SA) immature king penguins (Aptenodytes patagonicus) compared with pre-fledging never-immersed (NI) birds. In vivo, experimental immersion into cold water stimulated a higher thermogenic response in SA penguins than in NI birds, but both groups exhibited hypothermia, a condition favouring oxidative stress. In vitro, the pectoralis muscles of SA birds displayed increased oxidative capacity and mitochondrial protein abundance but unchanged reactive oxygen species (ROS) generation per g tissue because ROS production per mitochondria was reduced. The genes encoding oxidant-generating proteins were down-regulated in SA birds while mRNA abundance and activity of the main antioxidant enzymes were up-regulated. Genes encoding proteins involved in repair mechanisms of oxidized DNA or proteins and in degradation processes were also up-regulated in SA birds. Sea life also increased the degree of fatty acid unsaturation in muscle mitochondrial membranes resulting in higher intrinsic susceptibility to ROS. Oxidative damages to protein or DNA were reduced in SA birds. Repeated experimental immersions of NI penguins in cold-water partially mimicked the effects of acclimatization to marine life, modified the expression of fewer genes related to oxidative stress but in a similar way as in SA birds and increased oxidative damages to DNA. It is concluded that the multifaceted plasticity observed after marine life may be crucial to maintain redox homeostasis in active tissues subjected to high pro-oxidative pressure

Workshop on cold-blanket research

International Nuclear Information System (INIS)

1977-05-01

The objective of the workshop was to identify and discuss cold-plasma blanket systems. In order to minimize the bombardment of the walls by hot neutrals the plasma should be impermeable. This requires a density edge-thickness product of nΔ > 10 15 cm -2 . An impermeable cold plasma-gas blanket surrounding a hot plasma core reduces the plasma wall/limiter interaction. Accumulation of impurities in this blanket can be expected. Fuelling from a blanket may be possible as shown by experimental results, though not fully explained by classical transport of neutrals. Refuelling of a reacting plasma had to be ensured by inward diffusion. Experimental studies of a cold impermeable plasma have been done on the tokamak-like Ringboog device. Simulation calculations for the next generation of large tokamaks using a particular transport model, indicate that the plasma edge profile can be controlled to reduce the production of sputtered impurities to an acceptable level. Impurity control requires a small fraction of the radial space to accomodate the cold-plasma layer. The problem of exhaust is, however, more complicated. If the cold-blanket scheme works as predicted in the model calculations, then α-particles generated by fusion will be transported to the cold outside layer. The Communities' experimental programme of research has been discussed in terms of the tokamaks which are available and planned. Two options present themselves for the continuation of cold-blanket research

To verify the relationship between coping strategies of people with chronic kidney disease undergoing hemodialysis and their clinical variables and lifestyle habits. It was developed a cross-sectional study that used the Coping Strategies Inventory of Folkman and Lazarus and a semi-structured questionnaire for collecting clinical variables and lifestyles of patients undergoing hemodialysis in the Urology and Nephrology Institute of São Jose do Rio Preto-SP (Brazil). Participants were 107 adults undergoing hemodialysis, with an average age of 51 years; 62.4% were men. The main causes of chronic kidney disease were chronic glomerulonephritis, diabetes mellitus, undetermined cause and hypertension. The most reported coping strategies were focused on emotion. There were greater coping scores among people who had diabetes, those who had leisure and those who referred religion. People who exercised and those who had undergone renal transplantation had more positive coping. Clinical variables of people undergoing hemodialysis can be sources of stress, and lifestyle habits are associated with coping strategies to mitigate the effects of stress.

Previous studies have found associations between individual healthy behaviors and reduced risk of gestational diabetes mellitus (GDM); however, the association of composite healthy lifestyle during pregnancy with GDM has not been examined. Participants in the Omega Study (n = 3,005), a pregnancy cohort study conducted in Washington State (1996-2008), reported information on diet, physical activity, smoking, and stress during early pregnancy. Lifestyle components were dichotomized into healthy/unhealthy and then combined into a total lifestyle score (range, 0-4). Regression models were used to determine relative risk of GDM (n = 140 cases) in relation to healthy lifestyle. Twenty percent of participants had a healthy diet, 66% were physically active, 95% were nonsmokers, and 55% had low stress. Each 1-point increase in lifestyle score was associated with a 21% lower risk of GDM (95% confidence interval: 0.65, 0.96) after adjustment for age, race, and nulliparity. Adjustment for prepregnancy body mass index, prepregnancy physical activity, and prepregnancy smoking attenuated the associations slightly. Associations were similar in normal-weight and overweight/obese women. In this study, a composite measure of healthy lifestyle during early pregnancy was associated with substantially lower GDM risk. Public health messaging and interventions promoting multiple aspects of a healthy lifestyle during early pregnancy should be considered for GDM prevention. © The Author(s) 2017.

Distributional limits of many tropical species in Florida are ultimately determined by tolerance to low temperature. An unprecedented cold spell during 2–11 January 2010, in South Florida provided an opportunity to compare the responses of tropical American crocodiles with warm-temperate American alligators and to compare the responses of nonnative Burmese pythons with native warm-temperate snakes exposed to prolonged cold temperatures. After the January 2010 cold spell, a record number of American crocodiles (n = 151) and Burmese pythons (n = 36) were found dead. In contrast, no American alligators and no native snakes were found dead. American alligators and American crocodiles behaved differently during the cold spell. American alligators stopped basking and retreated to warmer water. American crocodiles apparently continued to bask during extreme cold temperatures resulting in lethal body temperatures. The mortality of Burmese pythons compared to the absence of mortality for native snakes suggests that the current population of Burmese pythons in the Everglades is less tolerant of cold temperatures than native snakes. Burmese pythons introduced from other parts of their native range may be more tolerant of cold temperatures. We documented the direct effects of cold temperatures on crocodiles and pythons; however, evidence of long-term effects of cold temperature on their populations within their established ranges remains lacking. Mortality of crocodiles and pythons outside of their current established range may be more important in setting distributional limits.

Polycystic ovary syndrome (PCOS) affects 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. Obesity worsens the presentation of PCOS and weight management (weight loss, maintenance or prevention of excess weight gain) is proposed as an initial treatment strategy, best achieved through lifestyle changes incorporating diet, exercise and behavioural interventions. To assess the effectiveness of lifestyle treatment in improving reproductive, anthropometric (weight and body composition), metabolic and quality of life factors in PCOS. Electronic databases (Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, PsycINFO, CINAHL, AMED) (date of last search 7/9/2010), controlled trials register, conference abstracts, relevant journals, reference lists of relevant papers and reviews and grey literature databases, with no language restrictions applied. Randomised controlled trials comparing lifestyle treatment (diet, exercise, behavioural or combined treatments) to minimal or no treatment in women with PCOS. Two authors independently selected trials, assessed methodological quality and risk of bias and extracted data. Six studies were included with n=164 participants. Three studies compared physical activity to minimal dietary and behavioural advice or no advice. Three studies compared combined dietary, exercise and behavioural interventions to minimal intervention. Risk of bias varied with 4/6 having adequate sequence generation and clinician or outcome assessor blinding and 3/6 having adequate allocation concealment, complete outcome data and being free of selective reporting.  There were no studies assessing the fertility primary outcomes of pregnancy, live birth and miscarriage and no data for meta-analysis on ovulation or menstrual regularity. Lifestyle intervention provided benefits when compared to minimal treatment for secondary reproductive, anthropometric and

Cross sectional study, in which a questionnaire containing sociodemographic, habits and health conditions variables was used. Forty-seven people with spinal cord injury participated and answered the self-report questionnaire. The group under study was predominantly male (92%), under 40 years of age (47%), and had low educational level (76%). The most frequent risk factors related to the lifestyle were: smoking (28%), alcohol consumption (36%), coffee consumption (92%) and being physically inactive (64%). Association was found between having four or more risk factors related to lifestyle and the loss of appetite, as well as constipation. . The actual inadequate lifestyle is associated with the health conditions of patients, and the nursing team should pay special attention to the education and promotion of health related to people with spinal cord injury.

Tip model of cold fission

International Nuclear Information System (INIS)

Goennenwein, F.; Boersig, B.

1991-01-01

Cold fission is defined to be the limiting case of nuclear fission where virtually all of the available energy is converted into the total kinetic energy of the fragments. The fragments have, therefore, to be born in or at least close to their respective ground states. Starting from the viewpoint that cold fission corresponds to most compact scission configurations, energy constraints have been exploited to calculate minimum tip distances between the two nascent fragments in binary fission. Crucial input parameters to this tip model of cold fission are the ground-state deformations of fragment nuclei. It is shown that the minimum tip distances being compatible with energy conservation vary strongly with both the mass and charge fragmentation of the fission prone nucleus. The tip distances refer to nuclei with equivalent sharp surfaces. In keeping with the size of the surface width of leptodermous nuclei, only configurations where the tip distances are smaller than a few fm may be considered as valid scission configurations. From a comparison with experimental data on cold fission this critical tip distance appears to be 3.0 fm for the model parameters chosen. Whenever the model calculation yields tip distances being smaller than the critical value, a necessary condition for attaining cold fission is considered to be fulfilled. It is shown that this criterion allows to understand in fair agreement with experiment which mass fragmentations are susceptible to lead to cold fission and which fragment-charge divisions are the most favored in each isobaric mass chain. Being based merely on energy arguments, the model cannot aim at predicting fragment yields in cold fission. However, the tip model proposed appears well suited to delineate the phase space where cold fission phenomena may come into sight. (orig.)

The fermented soybean product natto is a popular traditional food in Japan and is considered a health supplement. NKCP®, a natto-derived dietary food supplement whose main component is bacillopeptidase F, has antithrombotic, fibrinolytic, and blood pressure-lowering effects. We examined whether daily intake of NKCP® effectively improves subjective symptoms in patients with lifestyle diseases in this cross-over, double-blind study. Fermented soya extract with subtilisin NAT (nattokinase) as the main component was used as an active placebo. A 4-week course of NKCP® significantly decreased the visual analog scale (VAS) score for shoulder stiffness from 42.3 to 32.4 (P=0.009), the VAS score for low back pain from 25.5 to 18.8 (P=0.02), and the VAS score for coldness of the extremities from 33.1 to 25.7 (P=0.002). However, no significant difference was found in the VAS score for headache. After a 4-week course of active placebo, no significant changes in the VAS score were found for any symptoms. The significant improvement in the symptoms secondary to blood flow disturbance was caused by the improvement in blood flow by NKCP®. The use of dietary supplements based on the Japanese traditional food natto helps to relieve subjective symptoms for patients with lifestyle diseases receiving medical care. PMID:25653551

The first meeting devoted to cold neutron sources was held at the Los Alamos National Laboratory on March 5--8, 1990. Cosponsored by Los Alamos and Oak Ridge National Laboratories, the meeting was organized as an International Workshop on Cold Neutron Sources and brought together experts in the field of cold-neutron-source design for reactors and spallation sources. Eighty-four people from seven countries attended. Because the meeting was the first of its kind in over forty years, much time was spent acquainting participants with past and planned activities at reactor and spallation facilities worldwide. As a result, the meeting had more of a conference flavor than one of a workshop. The general topics covered at the workshop included: Criteria for cold source design; neutronic predictions and performance; energy deposition and removal; engineering design, fabrication, and operation; material properties; radiation damage; instrumentation; safety; existing cold sources; and future cold sources.

Purpose: To improve the reliability and the durability of cold traps by simplifying the structure and recycling liquid metals without using electromagnetic pumps. Constitution: The reactor container is partitioned by an intermediate container enhousing primary recycling pumps and cold traps. The inlet and the exit for the liquid metal of each cold trap are opened to the outside and the inside of the intermediate container respectively. In such a structure, the pressure difference between the inside and the outside of the intermediate container is exerted on the cold traps due to the exhaust pressure of the recycling pumps in which the liquid metal flowing into the cold traps is purified through filters, cooled and then discharged from the exit to the cold plenum. In this way, liquid metal can be recycled without using an electromagnetic pump whose reliability has not yet been established. (Kamimura, M.)

Full Text Available Background: The prevalence of asthma in adults varied from 0.96% to 11.03% while in children ranged from 2.3% to 11.9% in India. A number of factors including genetic predisposition, environment, and lifestyle factors including dietary habits influence the development and expression of asthma. The goal of asthma treatment is to achieve and maintain clinical control, which can be achieved in a majority of patients with pharmacologic intervention strategy. Objective: To assess the role of diet and lifestyle factors in asthma control in Indian population. Materials and Methods: Diagnosed asthma patients (aged 12-40 years were enrolled from the outpatient clinics. All patients were followed up and reassessed after 4 weeks with asthma control test (ACT and dietary and lifestyle questionnaire. The assessment of dietary pattern was performed by food frequency questionnaire (Nordic Nutrition Recommendations-Danish Physical Activity Questionnaire. The lifestyle factor included body mass index, smoking status, tobacco chewing, alcohol consumption, duration of travel (h/week, mental stress (visual analog scale: 0-10, sports activity - h/day, television (TV watching/video games - h/day, duration of sleep - h/day. Results: Seventy-five asthma patients (43 males and 32 females were divided into three groups according to ACT, 18 (24% patients in poorly-controlled asthma, 35 (46.7% in well-controlled asthma, and 22 (29.3% patients with totally-controlled asthma. Increased consumption of vegetables and cereals in patients with total-controlled asthma while increased consumption of sugar, nonvegetarian, fast food, salted and fried snacks in patients with poorly-controlled asthma. Poorly-controlled asthma had the highest duration of watching TV and sleep and least duration of travel and sports, though the results failed to reach statistical significance. Conclusion: The dietary and lifestyle factors too contribute to degree of control of asthma in India.

Assess the evolution of cardiovascular lifestyle behaviors in hypercholesterolemic patients concomitantly with changes in their daily intake of phytosterol-supplemented yoghurt (Phyto-SY). Nationwide prospective observational study conducted in general practices across France and Spain. Each practitioner suggested lifestyle changes to five consecutive patients with hypercholesterolemia (whether or not they were taking hypocholesterolemic drugs) and recommended daily consumption of Phyto-SY. The study design involved an inclusion visit, a patient's self-monitoring assessment after 1 month, and a final visit after 4 months. Primary evaluation criterion: changes in dietary habits assessed by a standardized Nutritional Lifestyle score. Secondary criteria: changes in lipid profile, anthropometry (waist circumference) and lifestyle behavior. A total of 2376 hypercholesterolemic patients (of whom 54.8% were women) were included. The average age was 56.2 years old. The Nutritional Lifestyle score improved from 15.4 ± 5.4 to 8.7 ± 4.0 (p 30 min) increased from 59.3% to 78.3% (p < 0.0001). The overweight rate decreased from 22.8% to 17.5% (p < 0.0001) and waist circumference from 94.6 ± 13.3 cm to 93.0 ± 12.8 cm (p < 0.0001).

Full Text Available Cardiovascular disease (CVD is the driving force behind the discrepancy in life expectancy between indigenous and non-indigenous groups in many countries. Preceding CVD many indigenous groups exhibit a cluster of cardiometabolic risk factors, including overweight-obesity, diabetes, high cholesterol, and high blood pressure. In turn, modifiable lifestyle risk factors contribute to the development of this cluster of cardiometabolic conditions. Modifiable lifestyle risk factors include, but are not limited to, physical inactivity, poor nutrition, excessive alcohol consumption, and cigarette smoking. Notably, these metabolic and lifestyle risk factors are relatively simple to monitor and track. The current review will look at modifiable cardiometabolic (overweight-obesity, diabetes mellitus, high cholesterol, and high blood pressure and lifestyle (physical inactivity, poor nutrition, risky alcohol behavior, and cigarette smoking risk factors among indigenous populations from Australia (Aboriginal Australians and Torres Strait Islanders, New Zealand (Mβori and the United States (Native Americans. Discussion will focus on the causal relationship between modifiable lifestyle risk factors and cardiometabolic outcomes, as well as, simple measurements for tracking these risk factors.

So Hyun Park

Full Text Available OBJECTIVES: This study investigated the prevalence and patterns of lifestyle risk behaviors in Korean adults. METHODS: We utilized data from the Fourth Korea National Health and Nutrition Examination Survey for 14,833 adults (>20 years of age. We used association rule mining to analyze patterns of lifestyle risk behaviors by characterizing non-adherence to public health recommendations related to the Alameda 7 health behaviors. The study variables were current smoking, heavy drinking, physical inactivity, obesity, inadequate sleep, breakfast skipping, and frequent snacking. RESULTS: Approximately 72% of Korean adults exhibited two or more lifestyle risk behaviors. Among women, current smoking, obesity, and breakfast skipping were associated with inadequate sleep. Among men, breakfast skipping with additional risk behaviors such as physical inactivity, obesity, and inadequate sleep was associated with current smoking. Current smoking with additional risk behaviors such as inadequate sleep or breakfast skipping was associated with physical inactivity. CONCLUSION: Lifestyle risk behaviors are intercorrelated in Korea. Information on patterns of lifestyle risk behaviors could assist in planning interventions targeted at multiple behaviors simultaneously.

We evaluated cold sensation at rest and in response to exercise-induced changes in core and skin temperatures in cold-sensitive exercise trained females. Fifty-eight trained young females were screened by a questionnaire, selecting cold-sensitive (Cold-sensitive, n  = 7) and non-cold-sensitive (Control, n  = 7) individuals. Participants rested in a room at 29.5°C for ~100 min after which ambient temperature was reduced to 23.5°C where they remained resting for 60 min. Participants then performed 30-min of moderate intensity cycling (50% peak oxygen uptake) followed by a 60-min recovery. Core and mean skin temperatures and cold sensation over the whole-body and extremities (fingers and toes) were assessed throughout. Resting core temperature was lower in the Cold-sensitive relative to Control group (36.4 ± 0.3 vs. 36.7 ± 0.2°C). Core temperature increased to similar levels at end-exercise (~37.2°C) and gradually returned to near preexercise rest levels at the end of recovery (>36.6°C). Whole-body cold sensation was greater in the Cold-sensitive relative to Control group during resting at a room temperature of 23.5°C only without a difference in mean skin temperature between groups. In contrast, cold sensation of the extremities was greater in the Cold-sensitive group prior to, during and following exercise albeit this was not paralleled by differences in mean extremity skin temperature. We show that young trained females who are sensitive to cold exhibit augmented whole-body cold sensation during rest under temperate ambient conditions. However, this response is diminished during and following exercise. In contrast, cold sensation of extremities is augmented during resting that persists during and following exercise. © 2017 The Authors.

1999-01-01

High-resolution AMS (accelerator-mass-spectrometer) radiocarbon dating was performed on late-glacial macrofossils in lake sediments from Kodiak Island, Alaska, and on shells in marine sediments from southwest Sweden. In both records, a dramatic drop in radiocarbon ages equivalent to a rise in the atmospheric C-14 by approximately 70%. coincides with the beginning of the cold period at 11000 yr B.P. (C-14 age). Thus our results show that a close correlation between climatic records around the globe is possible by using a global signature of changes in atmospheric C-14 content.

Adult attention-deficit/hyperactivity disorder (ADHD) has been added as a diagnosis to the Diagnostic and Statistical Manual of Mental Disorders version 5 (DSM5) in 2013, thus making ADHD, which has been classically known as a childhood disorder, a life-long disorder. Those suffering from the condition show very specific behavioral traits, which manifest as lifestyle habits; they also show comorbidities that can be the symptoms and/or consequences of certain lifestyles. The targeted population was adults aged 18-65 years. The total sample was 1,012 (507 males and 505 females). The Adult ADHD Self-Report Scale (ASRS V. 1.1) was administered to evaluate the current symptoms of ADHD and a questionnaire regarding lifestyles that are pertinent to ADHD, exercise, drug use, and diet. An ASRS score of 4-6 points was found in 11.4% of the male population and 9.7% of the female population (5-6 points indicate very high-intensity symptoms). A score of 6, the highest intensity of symptomatology, was found in 1.18% of males and 0.99% of females. Gender differences in scores were not statistically significant. In terms of self-reported lifestyles, we calculated an ordered logistic regression and the odds ratios of those with ASRS scores >4. Those with higher ASRS scores had higher rates of self-reported unhealthy lifestyles and poor diets with high consumption of sweets. We also ascertained a paradoxical finding that is not in line with the current literature on the disorder - lower rates of cigarette smoking among people with higher ADHD symptomatology. Several specific lifestyles were found to be associated with higher ADHD symptoms such as poor diet and cannabis use. Other factors classically associated with the disorder such as cocaine addiction and nicotinism were either insignificant or surprisingly less prominent among the Czech sample. However, ADHD-prone respondents reported to be more physically active, which fits the clinical picture of hyperactivity but contrasts

Overseas-born-women from certain ethnicities are at high risk of type-2 diabetes and related metabolic disorders. This study explored the barriers and facilitators to long-term healthy lifestyle recommendations among Australian-born and overseas-born-women who attended health promotion sessions at a tertiary Australian Hospital for gestational diabetes 3-4 years previously. Face-to-face semi-structured interviews were conducted. Data were analyzed to identify major themes and the differing experiences of both groups of women. Women in both groups faced many barriers to improve post-gestational-diabetes lifestyle. Women from both groups recalled healthy lifestyle recommendations for during pregnancy they received at the service, but had difficulty recalling the long-term lifestyle recommendations. Timing of the health information, non-reiteration of lifestyle recommendations, uncoordinated and fragmented health system support after childbirth were barriers faced by all women. Additional barriers for overseas-born women included the cultural competence of the health education material, their cultural preferences for food and physical activities and unsupportive family and partner. Both groups had excellent compliance with the first annual postnatal oral-glucose-tolerance-test. This was attributed to the personal motivation and health professional reminder. Women only reverted to the healthy lifestyles postnatally for weight loss. A better understanding of the barriers to healthy lifestyle by women in their everyday lives will assist in the development of culturally appropriate health promotion guidelines and strategies. Constant un-fragmented postnatal engagement by the specialised diabetes clinics and primary health care services is crucial to sustain the healthy lifestyle in the long-term for women with previous gestational-diabetes.

Healthful lifestyles before and during pregnancy are important to facilitate healthy outcomes for mother and baby. For example, behaviors such as a sedentary lifestyle and consuming an energy-dense/nutrient-poor diet increase the risk of overweight/obesity before pregnancy and excessive weight gain during pregnancy, leading to adverse maternal and child health outcomes. Maternal psychopathology may be implicated in the development of suboptimal maternal lifestyle behaviors before and during pregnancy, perhaps through impacts on motivation. This article explores this notion using maternal obesity and excessive gestational weight gain as examples of the health impacts of psychological states. We suggest that factors such as psychological well-being, individual motivation for behavior change, and broader environmental influences that affect both individual and system-wide determinants all play important roles in promoting healthy lifestyles periconception and are key modifiable aspects for intervention designers to consider when trying to improve dietary behaviors and increase physical activity before and during pregnancy. In addition, implementing system-wide changes that impact positively on individual and environmental barriers to behavior change that are sustainable, measureable, and effective is required.

The role of lifestyle in preventing low birth weight.

Lifestyle behaviors such as cigarette smoking, weight gain during pregnancy, and use of other drugs play an important role in determining fetal growth. The relationship between lifestyle risk factors and low birth weight is complex and is affected by psychosocial, economic, and biological factors. Cigarette smoking is the largest known risk factor for low birth weight. Approximately 20% of all low birth weight could be avoided if women did not smoke during pregnancy. Reducing heavy use of alcohol and other drugs during pregnancy could also reduce the rate of low birth weight births. Pregnancy and the prospect of pregnancy provide an important window of opportunity to improve women's health and the health of children. The adoption before or during pregnancy of more healthful lifestyle behaviors, such as ceasing to smoke, eating an adequate diet and gaining enough weight during pregnancy, and ceasing heavy drug use, can positively affect the long-term health of women and the health of their infants. Detrimental lifestyles can be modified, but successful modification will require large-scale societal changes. In the United States, these societal changes should include a focus on preventive health, family-centered workplace policies, and changes in social norms.

Integration is an emerging concept in the study of self-management and chronic illness, yet this process and how it occurs is not well understood. This investigation, part of a triangulated study, focused on the experience of integrating type 2 diabetes treatment recommendations into an existing lifestyle while participating in a nurse-coaching intervention. An interpretive method elicited data from nurse-coaching sessions (4), field notes, and an interview in 9 women with type 2 diabetes. The process of data reduction and analysis (Miles & Huberman, 1994) was used to interpret data. The core process of integrating lifestyle change in type 2 diabetes was multifaceted and complex. Challenges to the process of integrating lifestyle change included reconciling emotions, composing a structure, striving for satisfaction, exploring self and conflicts, discovering balance, and developing a new cadence to life. These challenges required acknowledgment in order for participants to progress toward integration. Balance was an integral component to the experience of integration, between structure and flexibility, fear and hope, conflict and acceptance, diabetes and life. Conceptualizations identified with this investigation extend understanding of theories of integration and lifestyle change and invite the development and testing of nursing interventions.

Modifying some lifestyle factors can be useful in depression, at least as an adjuvant treatment. Combining different lifestyle interventions seems to be an adequate strategy to increase their antidepressant efficacy according with preliminary studies, but this issue has not been enough investigated. The present study is a randomized, double-blinded, multicentre, two arm-parallel clinical trials, with a 12 month follow-up. The sample consisted of 273 Primary Care patients. Four combined hygienic-dietary written recommendations were given to the patients about diet, exercise, light exposure and sleep hygiene. Both active and control interventions were associated with improvement on BDI (Beck Depression Inventory) scores. However, there were not statistically significant differences (7.0 vs. 7.6; p=0.594). We were unable to monitor whether patients carry out recommendations. Intervention could be too difficult to accomplish for depressed patients without enough support and supervision. Just giving written lifestyle recommendations are not enough for depressive patients to benefit from them, so perhaps lifestyle change recommendations work or do not work on Depression depending on how they are presented to patients and on monitoring systems of their implementation.

Full Text Available Active volcanoes in Antarctica contrast with their predominantly cold surroundings, resulting in environmental conditions capable of selecting for versatile and extremely diverse microbial communities. This is especially true on Deception Island, where geothermal, marine, and polar environments combine to create an extraordinary range of environmental conditions. Our main goal in this study was to understand how microbial community structure is shaped by gradients of temperature, salinity, and geochemistry in polar marine volcanoes. Thereby, we collected surface sediment samples associated with fumaroles and glaciers at two sites on Deception, with temperatures ranging from 0 to 98°C. Sequencing of the 16S rRNA gene was performed to assess the composition and diversity of Bacteria and Archaea. Our results revealed that Deception harbors a combination of taxonomic groups commonly found both in cold and geothermal environments of continental Antarctica, and also groups normally identified at deep and shallow-sea hydrothermal vents, such as hyperthermophilic archaea. We observed a clear separation in microbial community structure across environmental gradients, suggesting that microbial community structure is strongly niche driven on Deception. Bacterial community structure was significantly associated with temperature, pH, salinity, and chemical composition; in contrast, archaeal community structure was strongly associated only with temperature. Our work suggests that Deception represents a peculiar “open-air” laboratory to elucidate central questions regarding molecular adaptability, microbial evolution, and biogeography of extremophiles in polar regions.

Imaging with cold neutrons

Neutrons for imaging purposes are provided mainly from thermal beam lines at suitable facilities around the world. The access to cold neutrons is presently limited to very few places only. However, many challenging options for imaging with cold neutrons have been found out, given by the interaction behavior of the observed materials with neutrons in the cold energy range (3-10 A). For absorbing materials, the interaction probability increases proportionally with the wavelength with the consequence of more contrast but less transmission with cold neutrons. Many materials are predominantly scattering neutrons, in particular most of crystalline structural materials. In these cases, cold neutrons play an important role by covering the energy range of the most important Bragg edges given by the lattice planes of the crystallites. This particular behavior can be used for at least two important aspects-choosing the right energy of the initial beam enables to have a material more or less transparent, and a direct macroscopic visualization of the crystalline structure and its change in a manufacturing process. Since 2006, PSI operates its second beam line for neutron imaging, where cold neutrons are provided from a liquid deuterium cold source (operated at 25 K). It has been designed to cover the most current aspects in neutron imaging research with the help of high flexibility. This has been done with changeable inlet apertures, a turbine based velocity selector, two beam positions and variable detector systems, satisfying the demands of the individual investigation. The most important detection system was found to be a micro-tomography system that enables studies in the presently best spatial resolution. In this case, the high contrast from the sample interaction process and the high detection probability for the cold neutrons combines in an ideal combination for the best possible performance. Recently, it was found out that the energy selective studies might become a

We investigated the impact of cold-water acclimation on whole-body fluid regulation using tracer-dilution methods to differentiate between the intracellular and extracellular fluid compartments. Seven euhydrated males [age 24.7 (8.7) years, mass 74.4 (6.4) kg, height 176.8 (7.8) cm, sum of eight skinfolds 107.4 (20.4) mm; mean (SD)] participated in a 14-day cold-water acclimation protocol, with 60-min resting cold-water stress tests [CWST; 18.1 (0.1) degrees C] on days 1, 8 and 15, and 90-min resting cold-water immersions [18.4 (0.4) degrees C] on intervening days. Subjects were immersed to the 4th intercostal space. Intracellular and extracellular fluid compartments, and plasma protein, electrolyte and hormone concentrations were investigated. During the first CWST, the intracellular fluid (5.5%) and plasma volumes were reduced (6.1%), while the interstitial fluid volume was simultaneously expanded (5.4%). This pattern was replicated on days 8 and 15, but did not differ significantly among test days. Acclimation did not produce significant changes in the pre-immersion distribution of total body water, or changes in plasma osmolality, total protein, electrolyte, atrial natriuretic peptide or aldosterone concentrations. Furthermore, a 14-day cold-water acclimation regimen did not elicit significant changes in body-fluid distribution, urine production, or the concentrations of plasma protein, electrolytes or the fluid-regulatory hormones. While acclimation trends were not evident, we have confirmed that fluid from extravascular cells is displaced into the interstitium during acute cold-water immersion, both before and after cold acclimation.

Obese pregnant women are the focus of numerous dietary and lifestyle intervention studies, however there is a paucity of literature examining the habitual dietary and lifestyle habits of this population. This paper aims to assess maternal dietary and lifestyle habits in an obese cohort, in order to identify priority areas to be addressed in future studies and in clinical practice. This prospective observational study recruited 100 pregnant women with a body mass index 30.0-39.9 kg/m(2) from routine antenatal clinics. Dietary intakes were assessed using a 3-day food diary and a structured lifestyle questionnaire assessed physical activity levels, smoking and alcohol habits and wellbeing. Macronutrient intakes as a percentage of total energy were not compliant to healthy eating guidelines with an inadequate intake of carbohydrate and excess intake of saturated fat. Compliance to recommended intakes of calcium, iron, folate and vitamin D was poor from diet alone. The consumption of energy dense food groups high in fat and sugar was greater than for published pregnant populations and the general female non-pregnant population. One-third of women reported engaging in weekly physical activity that would comply with recommendations for pregnant women while 25 % reported low mood status indicating potential depression. High intakes of energy-dense processed foods and poor compliance to micronutrient recommendations are critical dietary issues of concern among obese pregnant women. Low mood is a barrier to motivation for changing behaviour which would also need to be addressed in future lifestyle intervention studies.

The Community Preventive Services Task Force recommends combined diet and physical activity promotion programs for people at increased risk of type 2 diabetes, as evidence continues to show that intensive lifestyle interventions are effective for overweight individuals with prediabetes. To illustrate the potential clinical and economic benefits of treating prediabetes with lifestyle intervention to prevent or delay onset of type 2 diabetes and sequelae. This 2014 analysis used a Markov model to simulate disease onset, medical expenditures, economic outcomes, mortality, and quality of life for a nationally representative sample with prediabetes from the 2003-2010 National Health and Nutrition Examination Survey. Modeled scenarios used 10-year follow-up results from the lifestyle arm of the Diabetes Prevention Program and Outcomes Study versus simulated natural history of disease. Over 10 years, estimated average cumulative gross economic benefits of treating patients who met diabetes screening criteria recommended by the ADA ($26,800) or USPSTF ($24,700) exceeded average benefits from treating the entire prediabetes population ($17,800). Estimated cumulative, gross medical savings for these three populations averaged $10,400, $11,200, and $6,300, respectively. Published estimates suggest that opportunistic screening for prediabetes is inexpensive, and lifestyle intervention similar to the Diabetes Prevention Program can be achieved for ≤$2,300 over 10 years. Lifestyle intervention among people with prediabetes produces long-term societal benefits that exceed anticipated intervention costs, especially among prediabetes patients that meet the ADA and USPSTF screening guidelines.

Pregnant women are generally more motivated to change their lifestyle habits compared with non-pregnant women. However, the ability to change these habits depends on the motivation to change. This study describes pregnant women's self-reported motivation and ability to change lifestyle habits and their relation to body mass index (BMI), self-rated health, educational level and country of origin. This cross-sectional study combined data from the Maternal Health Care Register in Västerbotten (MHCR-VB) and the Salut Programme Register (Salut-R). Data were collected from 3,868 pregnant residents in Västerbotten County (northern Sweden) between 2011 and 2012. Chi-square test, two independent samples t-test and univariate and multivariate logistic regression were performed. Most of the pregnant women (61.3%) were satisfied with their self-reported lifestyle habits irrespective of BMI, self-rated health, educational level, and country of origin. Many reported that they wanted to increase their physical activity, improve their dietary habits, and reduce their weight. In general, they estimated their ability to change their lifestyle habits as equal to their motivation of change. Women who reported a large or very large motivation to change their lifestyle habits were characterized by higher BMI and higher educational level. Most of the participating pregnant women were satisfied with their lifestyle habits, although they reported being further motivated to change some of them. Health care professionals encountering fertile and pregnant women may have a unique opportunity to support and promote lifestyle changes, taking into account women's motivation for change. Future research should focus on factors that motivate pregnant women to change their lifestyle, explore barriers for change of lifestyle and how support best may be provided to pregnant women. In addition, studies on lifestyle and motivation for lifestyle change from non-Nordic countries are called for. Copyright

The molecular and cellular basis of cold sensation.

Science.gov (United States)

McKemy, David D

2013-02-20

Of somatosensory modalities, cold is one of the more ambiguous percepts, evoking the pleasant sensation of cooling, the stinging bite of cold pain, and welcome relief from chronic pain. Moreover, unlike the precipitous thermal thresholds for heat activation of thermosensitive afferent neurons, thresholds for cold fibers are across a range of cool to cold temperatures that spans over 30 °C. Until recently, how cold produces this myriad of biological effects has been poorly studied, yet new advances in our understanding of cold mechanisms may portend a better understanding of sensory perception as well as provide novel therapeutic approaches. Chief among these was the identification of a number of ion channels that either serve as the initial detectors of cold as a stimulus in the peripheral nervous system, or are part of rather sophisticated differential expression patterns of channels that conduct electrical signals, thereby endowing select neurons with properties that are amenable to electrical signaling in the cold. This review highlights the current understanding of the channels involved in cold transduction as well as presents a hypothetical model to account for the broad range of cold thermal thresholds and distinct functions of cold fibers in perception, pain, and analgesia.

The aim of the present study was to evaluate the local cold tolerance of older Korean female divers, haenyeo ( N = 22) in terms of cold acclimatization and ageing. As control groups, older non-diving females ( N = 25) and young females from a rural area ( N = 15) and an urban area ( N = 51) participated in this study. To evaluate local cold tolerance, finger cold-induced vasodilation (CIVD) during finger immersion of 4 °C water was examined. As a result, older haenyeos showed greater minimum finger temperature and recovery finger temperature than older non-diving females ( P < 0.05), but similar responses in onset time, peak time, maximum finger temperature, frequency of CIVD, heart rate, blood pressure, and thermal and pain sensations as those of older non-diving females. Another novel finding was that young urban females showed more vulnerable responses to local cold in CIVD variables and subjective sensations when compared to older females, whereas young rural females had the most excellent cold tolerance in terms of maximum temperature and frequency of CIVD among the four groups ( P < 0.05). The present results imply that older haenyeos still retain cold acclimatized features on the periphery even though they changed their cotton diving suits to wet suits in the early 1980s. However, cardiovascular responses and subjective sensations to cold reflect aging effects. In addition, we suggest that young people who have been adapted to highly insulated clothing and indoor heating systems in winter should be distinguished from young people who were exposed to less modern conveniences when compared to the aged in terms of cold tolerance.

Full Text Available Smoking is harmful for one’s health and affects many people in the world. Its consequences are high morbidity and mortality from cardio-respiratory diseases and cancer. This complex public health issue also entails high costs. In order to understand this addiction, it is necessary to find out whether its presence is an isolated habit or a part of an unhealthy behavior. Objective: to explore the relationship between smoking and some components of a lifestyle. Methodology: a cross-sectional study with 4,000 adults aiming at identifying the link between smoking and certain aspects of lifestyle such as age, gender, education, socioeconomic level, physical inactivity, eating habits, recreation and alcohol. Results: age and socioeconomic level were not found to be associated with smoking; however, gender, schooling level, alcohol consumption, physical inactivity, unhealthy eating habits, and inadequate recreation were found to be statistically and epidemiologically related to smoking. Conclusions: smoking is associated with other adverse components of an unhealthy lifestyle. Community control and health promotion activities should address this issue through comprehensive strategies aimed at modifying human behavior in order to achieve more effective results.

Step counting (using pedometers or accelerometers) is widely accepted by researchers, practitioners, and the general public. Given the mounting evidence of the link between low steps/day and time spent in sedentary behaviours, how few steps/day some populations actually perform, and the growing interest in the potentially deleterious effects of excessive sedentary behaviours on health, an emerging question is "How many steps/day are too few?" This review examines the utility, appropriateness, and limitations of using a reoccurring candidate for a step-defined sedentary lifestyle index: 10 000) to lower (sedentary lifestyle index for adults is appropriate for researchers and practitioners and for communicating with the general public. There is little evidence to advocate any specific value indicative of a step-defined sedentary lifestyle index in children and adolescents.

The Lapinlahti 2005 study was carried out to explore cardiovascular disease risk factors, lifestyle and quality of life in Lapinlahti residents in eastern Finland. Our aim was to study the association between lifestyle and health-related quality of life (HRQoL) in the community. The present study is based on the baseline data of the followed up (2005-2010) population-based cohort (N = 376, n of males = 184). A trained research nurse measured weight, height, waist circumference and blood pressure. Self-reported HRQoL was measured using a 15D questionnaire. A BDI-21 inventory was used to assess the presence of self-reported depressive symptoms. Lifestyle factors (nutrition, exercise, smoking and alcohol use) were examined with a structured questionnaire. Each lifestyle item was valued as -1, 0 or 1, depending on how well it corresponded to the recommendations. Based on the index the participants were divided into three lifestyle sum tertiles: I = unhealthy, II = neutral and III = healthy. The age- and sex-adjusted linear trend between the tertiles was tested. The 15D score had a positive linear relationship with the lifestyle tertiles (P = .0048 for linearity, age- and sex-adjusted). Respectively, self-reported depressive symptoms were less frequent among subjects with a healthier lifestyle (P = .038). People who are expected to strive most to change their lifestyle have the lowest quality of life and psychological welfare, which should be taken into account in both clinical work and health promotion.

Marine habitat mapping has recently become essential in coastal marine science research. It is one of the efforts to understand marine ecosystems, and thus to protect them. Habitat mapping is integral to marine-related industries such as fisheries, aquaculture, forestry and tourism. An assessment of marine habitat mapping was conducted at Labuan Marine Park (LMP), a marine protected area in the Federal Territory of Labuan. It is surrounded by shallow water within its islands (Kuraman, Rusukan Kecil and Rusukan Besar) with an area of 39.7 km2. The objectives of the study are to identify the substrate and types of marine habitat present within the park. Side scan sonar (SSS) (Aquascan TM) was used to determine the substrates and habitat while ground truthings were done through field observation and SCUBA diving survey. Seabed classification and marine habitat was based on NOAA's biogeography program. Three substrate types (sand, rock, silt) were identified in this area. The major marine habitats identified are corals, macro algae and small patches of sea grass. The study area is an important refuge for spawning and juvenile fish and supports the livelihood of the coastal communities on Labuan Island. Therefore, proper management is crucial in order to better maintain the marine protected area. The findings are significant and provide detailed baseline information on marine habitat for conservation, protection and future management in LMP.

Extreme ocean waves in the Caribbean Sea are commonly related to the effects of storms and hurricanes during the months of June through November. The collapse of 200 m of the Puerto Colombia pier in March 2009 revealed the effects of meteorological phenomena other than storms and hurricanes that may be influencing the extreme wave regime in the Colombian Caribbean. The marked seasonality of these atmospheric fronts was established by analyzing the meteorological-marine reports of the Instituto de Hidrología, Meteorología y Estudios Ambientales of Colombia (IDEAM, based on its initials in Spanish) and the Centro de Investigación en Oceanografía y Meteorología of Colombia (CIOH, based on its initials in Spanish) during the last 16 yr. The highest number of cold fronts was observed during the months of January, February, and March, with 6 fronts occurring per year. An annual trend was observed and the highest number of fronts occurred in 2010 (20 in total); moreover, an annual strong relationship between the maximum average wave values and the cold fronts in the central zone of the Colombian Caribbean during the first three months of the year was established. In addition, the maximum values of the significant height produced by the passage of cold fronts during the last 16 yr were identified. Although the Colombian Caribbean has been affected by storms and hurricanes in the past, this research allows us to conclude that there is a strong relationship between cold fronts and the largest waves in the Colombian Caribbean during the last 16 yr, which have caused damage to coastal infrastructure. We verified that the passage of a cold front corresponded to the most significant extreme wave event of the last two decades in the Colombian Caribbean, which caused the structural collapse of the Puerto Colombia pier, located near the city of Barranquilla, between 5 and 10 March 2009. This information is invaluable when evaluating average and extreme wave regimes for the

An overview of literature about isolating biosurfactant producers from marine sources indicated no such producers have been reported form North Atlantic Canada. Water and sediment samples were taken from petroleum hydrocarbon contaminated coastal and offshore areas in this region. Either n-hexadecane or diesel was used as the sole carbon source for the screening. A modified colony-based oil drop collapsing test was used to cover sessile biosurfactant producers. Fifty-five biosurfactant producers belong to genera of Alcanivorax, Exiguobacterium, Halomonas, Rhodococcus, Bacillus, Acinetobacter, Pseudomonas, and Streptomyces were isolated. The first three genera were established after 1980s with interesting characteristics and limited relevant publications. Some of the 55 isolated strains were found with properties such as greatly reducing surface tension, stabilizing emulsion and producing flocculant. Isolates P6-4P and P1-5P were selected to demonstrate the performance of biosurfactant production, and were found to reduce the surface tension of water to as low as 28 dynes/cm.

Increased plasma total homocysteine (Hcy) is a known cardiovascular disease (CVD) risk factor, related to several components of the established CVD risk profile. Observational studies support the role of modifying life-style related risk factors such as diet, physical activity and alcohol consumption in CVD prevention. Regular physical activity protects against coronary artery disease, possibly through its role in controlling risk factors such as hypertension, diabetes mellitus and obesity, but also independently. The aim of our study was to test the hypothesis that there is an association between physical activity, life-style habits and plasma Hcy levels in an elderly population. In this cross-sectional study, 423 males and females aged 69.0 +/- 6.7 years completed an interview and laboratory examinations. Our main outcome measure was plasma levels of Hcy. Mean Hcy values were 10.5 +/- 5.5 micromol/L (11.4 +/- 6.1 for males and 9.3 +/- 4.5 for females; p sedentary life-style, 17% higher amongst males, 1% higher for each one-year increment in age, and 10% higher amongst participants who used no B vitamin supplements. Any level of physical activity was found to be an independent life-style habit associated with a lower Hcy level in an elderly population. This study supports existing recommendations for elderly persons to maintain a physically active life-style.

The anaerobic oxidation of methane (AOM) with sulfate controls the emission of the greenhouse gas methane from the ocean floor. AOM is performed by microbial consortia of archaea (ANME) associated with partners related to sulfate-reducing bacteria. In vitro enrichments of AOM were so far only successful at temperatures ≤25 °C; however, energy gain for growth by AOM with sulfate is in principle also possible at higher temperatures. Sequences of 16S rRNA genes and core lipids characteristic for ANME as well as hints of in situ AOM activity were indeed reported for geothermally heated marine environments, yet no direct evidence for thermophilic growth of marine ANME consortia was obtained to date. To study possible thermophilic AOM, we investigated hydrothermally influenced sediment from the Guaymas Basin. In vitro incubations showed activity of sulfate-dependent methane oxidation between 5 and 70 °C with an apparent optimum between 45 and 60 °C. AOM was absent at temperatures ≥75 °C. Long-term enrichment of AOM was fastest at 50 °C, yielding a 13-fold increase of methane-dependent sulfate reduction within 250 days, equivalent to an apparent doubling time of 68 days. The enrichments were dominated by novel ANME-1 consortia, mostly associated with bacterial partners of the deltaproteobacterial HotSeep-1 cluster, a deeply branching phylogenetic group previously found in a butane-amended 60 °C-enrichment culture of Guaymas sediments. The closest relatives (Desulfurella spp.; Hippea maritima) are moderately thermophilic sulfur reducers. Results indicate that AOM and ANME archaea could be of biogeochemical relevance not only in cold to moderate but also in hot marine habitats.

The prevalence of childhood obesity has been increasing but the causes are not fully understood. Recent public health interventions and guidance aiming to reduce childhood obesity have focused on the whole family, as opposed to just the child but there remains a lack of empirical evidence examining this relationship. Using data from the longitudinal Millennium Cohort Study (MCS), we investigate the dynamic relationship between underlying family lifestyle and childhood obesity during early childhood. The MCS interviewed parents shortly after the birth of their child and follow up interviews were carried out when the child was 3, 5 and 7 years. We use a dynamic latent factor model, an approach that allows us to identify family lifestyle, its evolution over time (in this case between birth and 7 years) and its influence on childhood obesity and other observable outcomes. We find that family lifestyle is persistent, 87.43% of families which were above the 95th percentile on the lifestyle distribution, remained above the 95th percentile when the child was 7 years old. Family lifestyle has a significant influence on all outcomes in the study, including diet, exercise and parental weight status; family lifestyle accounts for 11.3% of the variation in child weight by age 7 years. The analysis suggests that interventions should therefore be prolonged and persuasive and target the underlying lifestyle of a family as early as possible during childhood in order to have the greatest cumulative influence. Our results suggest that children from advantaged backgrounds are more likely to be exposed to healthier lifestyles and that this leads to inequalities in the prevalence of obesity. To reduce inequalities in childhood obesity, policy makers should target disadvantaged families and design interventions specifically for these families.

Computer usage and its relationship with adolescent lifestyle in Hong Kong.

To determine the patterns of computer usage among adolescents in Hong Kong and to examine whether computer usage is associated with less physical activity and social support among adolescents. A total of 2110 secondary school students (52% boys and 48% girls) in Hong Kong completed a set of questionnaires to measure their computer usage and lifestyle. Mean age of the respondents was 14.16 years (SD = 1.81 years). Computer usage was taped by asking the students to indicate how much time (in minutes) they spent on the computer each day for doing homework assignments; playing computer games; "surfing" the Internet; and communicating with others. The students also provided information on their social-physical lifestyle. Student's t-tests and analysis of variance were used to examine group differences. Pearson product moment correlations were used to explore relationships between computer usage and lifestyle. Boys who use computers for doing homework, "surfing" the Internet, and communicating with others engage in more social-physical activities than others. Boys who use computers to play games tend to be more social-behaviorally inactive. For girls, patterns of computer usage are not related to lifestyle. Computer users tended to engage in social-physical activities more frequently and had higher social support than nonusers. But among computer users, the amount of time spent daily on the computer was not associated with lifestyle. Instead, patterns of computer usage are more related to lifestyle and the relationship is moderated by gender.

Full Text Available Background: Factors affecting lifestyle become one of the most priorities of the research field, especially in adolescents and youth. Using a qualitative approach, this study aimed to understand what factors are affecting young people's healthy lifestyle. Methods: Using the conventional content analysis, and used the semi-structured in-depth interviews, we conducted a qualitative study to elicit the youth opinion considering their lifestyle affecting factors. Initially, purposeful sampling method was considered for data collection. Participants were selected from volunteered youths 18–30 years whom were selected from the Tehran city. Inclusion criteria for the participants were; (a willingness to participate in the study, and (b ability to express experiences. Results: According to findings, although the majority of participants agreed on the important role of lifestyle related behaviors in their healthy life, the lack of essential motivation and the pressure of educational assignments remove it from their daily program priorities. The most important barrier to observing the healthy lifestyle was expressed as; the acceptance of the concept by the individual and the social and economic potential of the individual. It was also suggested that practical interventions should focus on improving more participator engagement of all of the related stakeholders. Conclusions: We proposed the participatory strategies for youth healthy lifestyle promotion. Through which based on a specific needs the assessment of different target groups, designing, development, and implementation of health programs led to more effective interventions.

Lifestyle issues for colorectal cancer survivors--perceived needs, beliefs and opportunities.

2013-01-01

As survival rates for patients treated with colorectal cancer (CRC) increase, it is important to consider the short- and long-term self-management needs. The current work aimed to explore perceived patient needs for advice on diet, activity and beliefs about the role of lifestyle for reducing disease recurrence. Forty colorectal cancer survivors, aged between 27 and 84, participated in six focus groups in community locations in the UK. The findings suggest that CRC survivors would welcome guidance on diet in the immediate posttreatment period to alleviate symptoms and fears about food choices. Many participants actively sought lifestyle advice but experienced confusion, mixed messages, culturally inappropriate guidance and uncertainty about evidence of benefit. There was scepticism over the role of diet and physical activity as causes of cancer, in part because people believed their lifestyles had been healthy and could not see how reinstating healthy behaviours would reduce future disease risk. The sense of changing lifestyle to 'stack the odds in their favour' (against recurrence) appeared a more meaningful concept than prevention per se. Those people who had made or maintained dietary changes highlighted the importance of these to contributing to wellbeing and a sense of control in their life. A dogmatic approach to lifestyle change may lead to perceptions of victim blaming and stigmatisation. Personalised, evidence informed, guidance on lifestyle choices does appear to be a much needed part of care planning and should be built in to survivorship programmes.

Early labor force exit is one of the major problems worldwide. The present study investigates the relationship between work ability and lifestyle. This study was conducted at a manufacturing plant in Tehran in 2012. All 851 male workers in this plant were included into the study and their work ability was assessed using the Work Ability Index (WAI). Based on the obtained scores, the participants were then classified into four work ability groups (poor, moderate, good, or excellent). Moreover, the participants' lifestyles were studied in three areas, including physical activity, cigarette smoking, and Body Mass Index (BMI). The average work ability index score was 42.07, ranging from 7-48. Among the participants, 6.4% (43), 6.5% (44), 38.3% (259), and 48.8% (330) were in the groups with poor, moderate, good, and excellent work ability, respectively. The results of logistic regression analysis showed that there is a significant relationship between work ability and lifestyle (cigarette smoking, BMI, and physical activity) even after adjustment for confounding variables (Pwork ability and lifestyle (physical activity, BMI, cigarette smoking). Therefore, it is recommended to implement a lifestyle quality enhancement program to improve work ability in working environments.

Marine Rhodobacteraceae (Alphaproteobacteria) are key players of biogeochemical cycling, comprise up to 30% of bacterial communities in pelagic environments and are often mutualists of eukaryotes. As 'Roseobacter clade', these 'roseobacters' are assumed to be monophyletic, but non-marine Rhodobacteraceae have not yet been included in phylogenomic analyses. Therefore, we analysed 106 genome sequences, particularly emphasizing gene sampling and its effect on phylogenetic stability, and investigated relationships between marine versus non-marine habitat, evolutionary origin and genomic adaptations. Our analyses, providing no unequivocal evidence for the monophyly of roseobacters, indicate several shifts between marine and non-marine habitats that occurred independently and were accompanied by characteristic changes in genomic content of orthologs, enzymes and metabolic pathways. Non-marine Rhodobacteraceae gained high-affinity transporters to cope with much lower sulphate concentrations and lost genes related to the reduced sodium chloride and organohalogen concentrations in their habitats. Marine Rhodobacteraceae gained genes required for fucoidan desulphonation and synthesis of the plant hormone indole 3-acetic acid and the compatible solutes ectoin and carnitin. However, neither plasmid composition, even though typical for the family, nor the degree of oligotrophy shows a systematic difference between marine and non-marine Rhodobacteraceae. We suggest the operational term 'Roseobacter group' for the marine Rhodobacteraceae strains.

Full Text Available Objective : To study the antecedent risk factors in the causation of gallstone disease in a hospital-based case control study. Materials and Methods: Cases (n = 150 from all age groups and both sexes with sonographically proven gallstones were recruited over a duration of 3 months from the surgical wards of a tertiary care teaching hospital. Modes of presentation were also noted among cases. Age- and sex-matched controls (n = 150 were chosen from among ward inmates admitted for other reasons. Univariate and multivariate logistic regression analyses were performed for selected sociodemographic, dietary, and lifestyle-related variables. Results : Females had a higher prevalence of gallstone disease than males (P 60 years was relatively more susceptible (28%. Prepubertal age group was least afflicted (3.3%. Univariate analysis revealed multiparity, high fat, refined sugar, and low fiber intakes to be significantly associated with gallstones. Sedentary habits, recent stress, and hypertension were also among the significant lifestyle-related factors. High body mass index and waist hip ratios, again representing unhealthy lifestyles, were the significant anthropometric covariates. However, only three of these, viz., physical inactivity, high saturated fats, and high waist hip ratio emerged as significant predictors on stepwise logistic regression analysis (P < 0.05. Conclusion : Gallstone disease is frequent among females and elderly males. Significant predictor variables are abdominal adiposity, inadequate physical activity, and high intake of saturated fats; thus representing high risk lifestyles and yet amenable to primary prevention.

Primary care nurses struggle with lifestyle counseling in diabetes care: a qualitative analysis

Elwyn Glyn

2010-05-01

Full Text Available Abstract Background Patient outcomes are poorly affected by lifestyle advice in general practice. Promoting lifestyle behavior change require that nurses shift from simple advice giving to a more counseling-based approach. The current study examines which barriers nurses encounter in lifestyle counseling to patients with type 2 diabetes. Based on this information we will develop an implementation strategy to improve lifestyle behavior change in general practice. Method In a qualitative semi-structured study, twelve in-depth interviews took place with nurses in Dutch general practices involved in diabetes care. Specific barriers in counseling patients with type 2 diabetes about diet, physical activity, and smoking cessation were addressed. The nurses were invited to reflect on barriers at the patient and practice levels, but mainly on their own roles as counselors. All interviews were audio-recorded and transcribed. The data were analyzed with the aid of a predetermined framework. Results Nurses felt most barriers on the level of the patient; patients had limited knowledge of a healthy lifestyle and limited insight into their own behavior, and they lacked the motivation to modify their lifestyles or the discipline to maintain an improved lifestyle. Furthermore, nurses reported lack of counseling skills and insufficient time as barriers in effective lifestyle counseling. Conclusions The traditional health education approach is still predominant in primary care of patients with type 2 diabetes. An implementation strategy based on motivational interviewing can help to overcome 'jumping ahead of the patient' and promotes skills in lifestyle behavioral change. We will train our nurses in agenda setting to structure the consultation based on prioritizing the behavior change and will help them to develop social maps that contain information on local exercise programs.

The concept of cold-formed light steel framing construction has been widespread after understanding its structural characteristics with massive research works over the years. Connection serves as one of the important elements for light steel framing in order to achieve its structural stability. Compared to hot-rolled steel sections, cold-formed steel connections perform dissimilarity due to the thin-walled behaviour. This paper aims to review current researches on cold-formed steel connections, particularly for screw connections, storage rack connections, welded connections, and bolted connections. The performance of these connections in the design of cold-formed steel structures is discussed. PMID:24688448

Cardiovascular disease (CVD) progression is modifiable through lifestyle behaviors. Community pharmacists are ideally placed to facilitate self-management of cardiovascular health however research shows varied pharmacist engagement in providing lifestyle advice. This study explored community pharmacists' experiences and perceptions of providing lifestyle advice to patients with CVD. Semi-structured interviews were conducted with fifteen pharmacists (1 supermarket; 7 multiple; 7 independent) recruited through multiple methods from community pharmacies across the Midlands, England. A thematic analysis was conducted using a Framework approach. Pharmacists categorized patients according to their perceptions of the patients' ability to benefit from advice. Many barriers to providing lifestyle advice were identified. Confidence to provide lifestyle advice varied, with pharmacists most comfortable providing lifestyle advice in conjunction with conversations about medicines. Some pharmacists felt lifestyle advice was an integral part of their role whilst others questioned whether pharmacists should give lifestyle advice at all, particularly when receiving no remuneration for doing so. Pharmacists viewed providing lifestyle advice as important but identified many barriers to doing so. Lifestyle advice provision was influenced by pharmacists' perceptions of patients. Professional identity and associated role conflict appeared to underpin many of the barriers to pharmacists providing lifestyle advice. Pharmacists may benefit from enhanced training to: increase their confidence to provide lifestyle advice; integrate lifestyle advice with regular pharmaceutical practice and challenge their perceptions of some patients' receptiveness to lifestyle advice and behavior change. Changes to the way UK pharmacists are remunerated may increase the provision of lifestyle advice. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

Nurses have an increased risk for non-communicable diseases (NCDs), along with a high prevalence of obesity, poor eating habits and insufficient physical activity. The aim of this study was to determine the health concerns, health priorities and barriers to living a healthy lifestyle among nurses and hospital management staff from public hospitals in the Western Cape Metropole, South Africa. Participants were purposively sampled (n = 103), and included management personnel (n = 9), night shift (n = 57) and day-shift nurses (n = 36). Twelve focus groups (FGDs) were conducted with nursing staff to obtain insight into nurses' health concerns, lifestyle behaviours and worksite health promotion programmes (WHPPs). Seven key informant interviews (KII) were conducted with management personnel, to gain their perspective on health promotion in the worksite. Thematic analysis was used to analyse the data with the assistance of Atlas.ti Qualitative Data Analysis Software. Night shift nurses frequently identified weight gain and living with NCDs such as hypertension as their main health concerns. Being overweight was perceived to have a negative impact on work performance. All nurses identified backache and exposure to tuberculosis (TB) as occupation-related health concerns, and both management and nurses frequently reported a stressful working environment. Nurses frequently mentioned lack of time to prepare healthy meals due to long working hours and being overtired from work. The hospital environment was perceived to have a negative influence on the nurses' lifestyle behaviours, including food service that offered predominantly unhealthy foods. The most commonly delivered WHPPs included independent counselling services, an online employee wellness programme offered by the Department of Health and wellness days in which clinical measures, such as blood glucose were measured. Nurses identified a preference for WHPPs that provided access to fitness facilities or

Full Text Available The objective of the study was to examine whether reasons to adopt vegetarian lifestyle differ significantly among generations. Using a Food Frequency Questionnaire (FFQ, we identified that 4% of the participants were vegans, 25% lacto-ovo-vegetarians, 4% pesco-vegetarians and 67% non-vegetarian. Younger people significantly agreed more with the moral reason and with the environmental reason. People ages 41–60 significantly agreed more with the health reason. There are significant differences across generations as to why people choose to live a vegetarian lifestyle.

Steel weldability. Underbead cold cracking

International Nuclear Information System (INIS)

Marquet, F.; Defourny, J.; Bragard, A.

1977-01-01

The problem of underbead cold cracking has been studied by the implant technique. This approach allows to take into account in a quantitative manner the different factors acting on the cold cracking phenomenon: structure under the weld bead, level of restraint, hydrogen content in the molten metal. The influence of the metallurgical factors depending from the chemical composition of the steel has been examined. It appeared that carbon equivalent is an important factor to explain cold cracking sensitivity but that it is not sufficient to characterize the steel. The results have shown that vanadium may have a deleterious effect on the resistance to cold cracking when the hydrogen content is high and that small silicon additions are beneficient. The influence of the diffusible hydrogen content has been checked and the important action of pre- and postheating has been shown. These treatments allow the hydrogen to escape from the weld before the metal has been damaged. Some inclusions (sulphides) may also decrease the influence of hydrogen. A method based on the implant tests has been proposed which allows to choose and to control safe welding conditions regarding cold cracking

This mismatch between our ancient physiology and the western diet and lifestyle underlies many so-called diseases of civilization, including coronary heart disease, obesity, hypertension, type 2 diabetes, epithelial cell cancers, autoimmune disease, and osteoporosis, which are rare or virtually absent in hunter–gatherers and other non-westernized populations. It is therefore proposed that the adoption of diet and lifestyle that mimic the beneficial characteristics of the preagricultural environment is an effective strategy to reduce the risk of chronic degenerative diseases.Keywords: Paleolithic, hunter–gatherers, Agricultural Revolution, modern diet, western lifestyle and diseases

Background: Coronary heart disease (CHD) is the leading cause of morbidity and mortality worldwide. The growth of ageing populations in developing countries with progressively urbanized lifestyles are major contributors. The key risk factors for CHD such as hypercholesterolemia, diabetes mellitus, and obesity are likely to increase in the future. These risk factors are modifiable through lifestyle. Objectives: To review current literature on the potential benefit of cholesterol lowering in CHD risk reduction with a particular focus on the evidence of non-pharmacological/lifestyle management of hypercholesterolemia. Methods: Medline/PubMed systematic search was conducted using a two-tier approach limited to all recent English language papers. Primary search was conducted using key words and phrases and all abstracts were subsequently screened and relevant papers were selected. The next tier of searching was conducted by (1) reviewing the citation lists of the selected papers and (2) by using PubMed weblink for related papers. Over 3600 reports were reviewed. Results: Target cholesterol levels set out in various guidelines could be achieved by lifestyle changes, including diet, weight reduction, and increased physical activity with the goal of reducing total cholesterol to hypercholesterolemia is an important cause of CHD. Non-pharmacological methods provide initial as well as long-term measures to address this issue. PMID:22998604

Lifestyle related diseases associated with physical inactivity and poor diet quality, represent a major health burden. This study assessed negative and positive health habits and health care utilization in healthy women (n = 50) and women with lifestyle related diseases such as polycystic ovary syndrome (PCOS) (n = 50), gestational diabetes mellitus (GDM) (n = 44) and type 2 diabetes (DM2) (n = 43). A significant difference existed across groups for negative health habits (P = .012) with a trend for positive health habits (P = .06) elevated in women with PCOS. Women with DM2 had the highest amount of health care utilization including doctors office visits (P women with DM2 but there were no differences in positive health habits across sub-groups. Encouraging lifestyle modification in women with precursor diseases such as GDM and PCOS is vital in order to prevent progression to DM2.

Having a modern application capable to automatically collect and process data from users, based on information and lifestyle answers is one of current challenges for researchers and medical science. The purpose of the current study is to integrate user experience design (UXD) in a cloud-based medical application to improve patient safety, quality of care and organizational efficiency. The process consists of collecting traditional and new data from patients and users using online questionnaires. A questionnaire dynamically asks questions about the user's current diet and lifestyle. After the user will introduce the data, the application will formulate a presumptive nutritional plan and will suggest different medical recommendations regarding a healthy lifestyle, and calculates a risk factor for diseases. This software application, by design and usability will be an efficient tool dedicated for fitness, nutrition and health professionals.

The aim of this study was to investigate students' health-related lifestyles and to identify barriers and social determinants of healthier lifestyles. An online survey, two focus groups and three in-depth interviews across 2014/2015. A stratified by school size and random sample ( n = 468) of university students answered a 67-item questionnaire comprising six scales: Rapid Assessment of Physical Activity, Rapid Eating and Activity Assessment for Patients-Short Version, CAGE, Fagerström Test for Nicotine Dependence, Warwick-Edinburgh Mental Wellbeing Scale short version, and ad hoc scale for drug use/misuse. Stratified by gender, χ 2 tests were run to test associations/estimate risks and three multivariate Logistic Regression models were adjusted. A thematic approach guided the analysis of qualitative data. A total of 60% of the respondents were insufficiently physically active, 47% had an unbalanced diet and 30% had low mental wellbeing. Alcohol drinkers versus abstinent were almost equally distributed. A total of 42% of alcohol drinkers reported getting drunk at least once a month. Smokers accounted for 16% of the respondents. Identified risk factors for suboptimal physical activity were as follows: being a woman, not using the university gym and smoking. Risk factors for unbalanced diet were low mental wellbeing and drug use. Poor mental wellbeing was predicted by unbalanced diet, not feeling like shopping and cooking frequently, and a lack of help-seeking behaviour in cases of distress. Qualitative analysis revealed seven thematic categories: transition to new life, university environment and systems, finances, academic pressure, health promotion on campus and recommendations. This study provides robust evidence that the health-related lifestyles of the student population are worrying and suggests that the trend in chronic diseases associated with unhealthy lifestyles sustained over years might be unlikely to change in future generations.

An effective bactericidal cold-marinating method for beef products is described, exploiting the synergism between soy sauce and natural compounds (carvacrol, CV or thymol, TM) to reduce microbiological risks. Beef slices inoculated with Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella Typhimurium (3.1-3.5logCFU/g) were marinated in a teriyaki sauce with or without CV and TM (0.3 and 0.5%). After 1, 3, and 7days at 4°C, indigenous microflora population, color, lipid oxidation, marinade uptake, and pH of marinated beef and leftover marinade samples were examined. Teriyaki sauce alone did not reduce or inhibit any of the target pathogens or indigenous bacteria, while 0.5% CV- or TM-containing teriyaki sauce inactivated all inocula without recovery within 7days (p0.05).

Night shift work has been linked to some chronic diseases. Modification of lifestyle by night work may partially contribute to the development of these diseases, nevertheless, so far epidemiological evidence is limited. The aim of the study was to explore association between night shift work and lifestyle factors using data from a cross-sectional study among blue-collar workers employed in industrial plants in Łódź, Poland. The anonymous questionnaire was self-administered among 605 employees (236 women and 369 men, aged 35 or more) - 434 individuals currently working night shifts. Distribution of the selected lifestyle related factors such as smoking, alcohol drinking, physical activity, body mass index (BMI), number of main meals and the hour of the last meal was compared between current, former, and never night shift workers. Adjusted ORs or predicted means were calculated, as a measure of the associations between night shift work and lifestyle factors, with age, marital status and education included in the models as covariates. Recreational inactivity (defined here as less than one hour per week of recreational physical activity) was associated with current night shift work when compared to never night shift workers (OR = 2.43, 95% CI: 1.13-5.22) among men. Alcohol abstinence and later time of the last meal was associated with night shift work among women. Statistically significant positive relationship between night shift work duration and BMI was observed among men (p = 0.029). This study confirms previous studies reporting lower exercising among night shift workers and tendency to increase body weight. This finding provides important public health implication for the prevention of chronic diseases among night shift workers. Initiatives promoting physical activity addressed in particular to the night shift workers are recommended.

To investigate associations between health-promoting lifestyle and suboptimal health status (SHS) in the population of Guangdong province. A cross-sectional survey was conducted in a clustered sample of 24 159 individuals aged 12-80 years from 2012 to 2013. Health-promoting lifestyle was assessed via the Health-Promoting Lifestyle Profile (HPLP-II), and SHS was evaluated using the medical examination report and Sub-health Measurement Scale V1.0 (SHMS V1.0). Of the 24159 participants, subjects with SHS (46.0%) and disease status (35.2%) accounted for a much higher percentage than healthy subjects (18.8%). Regression analyses revealed a significant association between health status and healthy lifestyle (PUnhealthy lifestyle was an important risk factor for SHS and disease, especially the former. Compared with the participants with a healthy lifestyle (minimal exposure), after demographic adjustment, subjects with a 'poor' lifestyle (maximal exposure) were at a 43 times higher risk of developing SHS (OR: 42.825, 95% CI: 30.567-59.997), those with a general lifestyle were at a 21 times higher risk of SHS (OR: 21.072, 95%CI: 17.258-25.729), and those with a suboptimal lifestyle had a 4 times higher risk (OR: 4.085, 95%CI: 3.352-4.979). In the general population, the major risk factors for SHS included poor stress management, poor self-actualization, inactive exercise and poor interpersonal relationship. s Unhealthy lifestyles are significantly related to an increased risk of SHS. Intervention of unhealthy lifestyles, controlling the risk factors of SHS, and rigorous management of the time window of SHS are necessary to promote the heath status.

Nutrition and lifestyle, known to modulate aging process and age-related diseases, might also affect telomerase activity. Short and dysfunctional telomeres rather than average telomere length are associated with longevity in animal models, and their rescue by telomerase maybe sufficient to restore cell and organismal viability. Improving telomerase activation in stem cells and potentially in other cells by diet and lifestyle interventions may represent an intriguing way to promote health-span in humans.
