The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation.

Relative influences of sex, race, environment, and HIV infection on body composition in adults. (1/7312)

BACKGROUND: The factors that control body composition in disease are uncertain. OBJECTIVE: We planned to compare the relative influences of HIV infection, sex, race, and environment on body composition. METHODS: We analyzed results of body composition studies performed by bioelectrical impedance analysis in 1415 adults from 2 cohorts: white and African American men and women from the United States, and African men and women (279 HIV-infected and 1136 control). The effects of sex and HIV infection on weight, body cell mass, and fat-free mass were analyzed by using both unadjusted and age-, weight-, and height-adjusted data. RESULTS: Control men weighed more and had more body cell mass and fat-free mass than did control women, although control women had more fat. The strongest correlates with body composition were height and weight, followed by sex. HIV infection, age, environment, and race. Control men and women weighed more and had more body cell mass, fat-free mass, and fat than did HIV-infected men. However, differences in body composition between HIV-infected and control groups were strongly influenced by sex. Of the differences in weight between HIV-infected and uninfected subjects, fat-free mass accounted for 51% in men but only 18% in women, in whom the remainder was fat. Sex effects were similar in African and American groups. CONCLUSIONS: Sex has a marked effect on the changes in body composition during HIV infection, with women losing disproportionately more fat than men. Sex-related differences in body composition were narrower in the HIV-infected groups. Race and environment had smaller effects than sex and HIV infection.  (+info)

Clinical, biochemical and molecular genetic features of Leber's hereditary optic neuropathy. (2/7312)

Leber's hereditary optic neuropathy (LHON) has traditionally been considered a disease causing severe and permanent visual loss in young adult males. In nearly all families with LHON it is associated with one of three pathogenic mitochondrial DNA (mtDNA) mutations, at bp 11778, 3460 or 14484. The availability of mtDNA confirmation of a diagnosis of LHON has demonstrated that LHON occurs with a wider range of age at onset and more commonly in females than previously recognised. In addition, analysis of patients grouped according to mtDNA mutation has demonstrated differences both in the clinical features of visual failure and in recurrence risks to relatives associated with each of the pathogenic mtDNA mutations. Whilst pathogenic mtDNA mutations are required for the development of LHON, other factors must be reponsible for the variable penetrance and male predominance of this condition. Available data on a number of hypotheses including the role of an additional X-linked visual loss susceptibility locus, impaired mitochondrial respiratory chain activity, mtDNA heteroplasmy, environmental factors and autoimmunity are discussed. Subacute visual failure is seen in association with all three pathogenic LHON mutations. However, the clinical and experimental data reviewed suggest differences in the phenotype associated with each of the three mutations which may reflect variation in the disease mechanisms resulting in this common end-point.  (+info)

Mitochondrial involvement in Parkinson's disease, Huntington's disease, hereditary spastic paraplegia and Friedreich's ataxia. (3/7312)

Respiratory chain dysfunction has been identified in several neurodegenerative disorders. In Friedreich's ataxia (FA) and Huntington's disease (HD), where the respective mutations are in nuclear genes encoding non-respiratory chain mitochondrial proteins, the defects in oxidative phosphorylation are clearly secondary. In Parkinson's disease (PD) the situation is less clear, with some evidence for a primary role of mitochondrial DNA in at least a proportion of patients. The pattern of the respiratory chain defect may provide some clue to its cause; in PD there appears to be a selective complex I deficiency; in HD and FA the deficiencies are most severe in complex II/III with a less severe defect in complex IV. Aconitase activity in HD and FA is severely decreased in brain and muscle, respectively, but appears to be normal in PD brain. Free radical generation is thought to be of importance in both HD and FA, via excitotoxicity in HD and abnormal iron handling in FA. The oxidative damage observed in PD may be secondary to the mitochondrial defect. Whatever the cause(s) and sequence of events, respiratory chain deficiencies appear to play an important role in the pathogenesis of neurodegeneration. The mitochondrial abnormalities induced may converge on the function of the mitochondrion in apoptosis. This mode of cell death is thought to play an important role in neurodegenerative diseases and it is tempting to speculate that the observed mitochondrial defects in PD, HD and FA result directly in apoptotic cell death, or in the lowering of a cell's threshold to undergo apoptosis. Clarifying the role of mitochondria in pathogenesis may provide opportunities for the development of treatments designed to reverse or prevent neurodegeneration.  (+info)

Plasma leptin concentrations in Pima Indians living in drastically different environments. (5/7312)

OBJECTIVE: Plasma leptin, an important signal for the regulation of energy stores, is known to be influenced by many hormonal factors, but may also be affected by behavioral and environmental factors. The purpose of this study was to investigate the impact of lifestyle (diet composition, level of physical activity) on plasma leptin concentrations among Pima Indians living in drastically different environments. RESEARCH DESIGN AND METHODS: We studied 224 Mexican Pima Indians (115 women, 109 men) living a traditional lifestyle in a remote, mountainous area of northwest Mexico and 418 U.S. Pima Indians (281 women, 137 men) living a North American lifestyle on the Gila River Indian Reservation in Arizona. We hypothesized that the absolute value of leptin would be lower in Mexican Pima Indians because of their lower percent body fat, but could be further influenced by their lifestyle, independent of body composition. RESULTS: Leptin concentration (enzyme-linked immunosorbent assay [ELISA]) was strongly correlated with percent fat (bioimpedance) in Mexican Pima Indians (r = 0.83, P < 0.0001) and U.S. Pima Indians (r = 0.86, P < 0.0001). Among U.S. Pima Indians, independent of percent fat, subjects with type 2 diabetes had lower leptin than nondiabetic subjects (difference = 6.9 +/- 1.0 ng/ml, P < 0.002). Among nondiabetic subjects, Mexican Pima Indians had lower absolute leptin concentrations than U.S. Pima Indians, but higher after adjustment for percent body fat, waist circumference, age, and sex. In a subset of 70 pairs of subjects matched for sex and percent body fat, leptin concentration was 4.4 +/- 1.0 ng/ml (P < 0.0001) higher in Mexican Pima Indians versus U.S. Pima Indians. CONCLUSIONS: These results suggest that independent of body composition, leptin concentration may be increased by environmental factors, such as a high-carbohydrate diet and a high level of physical activity.  (+info)

Lipoprotein(a) levels and apolipoprotein(a) isoforms related to life style risk factors. (6/7312)

Lipoprotein(a) [Lp(a)] has been considered to be a predictor of premature coronary heart disease and other cardiovascular diseases. Lp(a) levels are largely genetically determined, but the detailed mechanism of Lp(a) elevation is uncertain. We examined the association between Lp(a) levels and apolipoprotein(a) [apo(a)] phenotypes as well as that of Lp(a) level and other various conditions. The subjects were 280 healthy Japanese (102 males and 178 females) aged 39 to 70 years who were living in a rural community in 1992. We obtained apo(a) phenotypes determined by SDS-PAGE as well as Lp(a) levels and other cardiovascular risk factors. We combined apo(a) phenotypes form 4 groups according to molecular weights (from high apo(a) molecular weight to low: I, II, III and IV). Lp(a) levels were associated with apo(a) phenotype-groups, that is, they were inversely associated with apo(a) molecular weight. Small apo(a) phenotypes were less frequent than large ones. The median Lp(a) level was higher in smoking (29.2 mg/dL) than in non-smoking subjects (18.5 mg/dL) in phenotype-group III. Adjusted means of total cholesterol and fibrinogen levels in apo(a) phenotype-group IV were the highest of all phenotype-groups. Age, apo(a) phenotype, smoking status, total cholesterol and fibrinogen were positively correlated with Lp(a) levels by multiple regression analysis. Lp(a) levels were found to be mainly associated with apo(a) phenotype, but varied broadly within the same apo(a) phenotype at various conditions, such as smoking status and high total cholesterol.  (+info)

Alternatives to minimize the environmental impact of large swine production units. (7/7312)

Large swine production facilities have become controversial additions to the agricultural landscape as their numbers and sizes have increased. In addition to being larger enterprises, these units have involved greater specialization, the influx of outside capital, and the employment of labor without extensive investment in the enterprise. Major complaints have included water pollution and odors. Water pollution complaints have been related to surface and groundwater resources. Accidental spills, structural failure, and purposeful discharges have been noted. Odor problems are most often related to manure management techniques. Large anaerobic lagoons and irrigation of lagoon effluent have the potential to emit odors that travel long distances. Fortunately, technology and management alternatives exist to achieve higher levels of environmental acceptability. More effective water pollution and odor control alternatives generally increase construction and operating costs. Producers, regulatory officials, and the local public have an opportunity to interact to achieve progress in establishing acceptable compromises. This article identifies the range of existing and evolving alternative strategies and provides some assistance to producers and neighbors in achieving the necessary equilibrium.  (+info)

Ocular development and involution in the European cave salamander, Proteus anguinus laurenti. (8/7312)

The anatomy and development of the eye of Proteus anguinus are described. The relationships between organogenesis of the eye in embryos and larva and its involution in the young and the adult are discussed. The availability (in breeding cultures) of a significant number of Proteus embryos (which are normally rare) allowed experimental analysis of the effects of light, xenoplastic differentiation and thyroid hormones on the development of the eye. The results of this study suggest that development and involution of the eye of Proteus are controlled by genetic factors which are not greatly influenced by environment, and one can, therefore, consider the microphthalmy of Proteus as a relict characteristic which is the result of a specific development with disturbance of the normal ontogenic process.  (+info)

Plant breeders consistently come up against the phenomenon of the genotype x environment interaction (GxE) in the activities of breeding programs, especially in the phases of evaluating genotypes for recommendation to producers. These genotypes are thoroughly evaluated through more replications, crop years, locations, and crop seasons. Always with the purpose of obtaining a genotype with high yields, wide adaptability and high stability of performance (Barili et al. 2015Barili LD, Vale NM, Prado AL, Carneiro JES, Silva FF and Nascimento M (2015) Genotype-environment interaction in common bean cultivars with carioca grain cultivated in Brazil in the last 40 years.

Hedonic Pricing Method relates differences in property prices (house and land prices) to variables in the surrounding environment. The basic principle is that property prices are affected to some extent by the characteristics of a particular environment effect. The environment effect can then be given a price tag based on house prices. An environment effect can be seen as positive (proximity to a recreational area, nice view) or negative (water pollution, risk of flooding). It may be to do with differences in time (time series data: prices in 1970 compared to prices in 2005 related to a change in the environment effect). It is also possible to analyse differences between areas with the same type of property but with one important difference in environment variable (cross-section data: the same type of housing in comparable environments with and without the environment effect). ...

Autism is a developmental disability with age of onset in childhood (under 3 years old), which is characterized by definite impairments in social interactions, abnormalities in speech, and stereotyped pattern of behaviors. Due to the progress of autism in recent decades, a wide range of studies have been done to identify the etiological factors of autism. It has been found that genetic and environmental factors are both involved in autism pathogenesis. Hence, in this review article, a set of environmental factors involved in the occurrence of autism has been collected, and finally, some practical recommendations for reduction of the risk of this devastating disease in children are represented.. ...

To increase tolerance to abiotic stresses in breeding programmes, typically families and collections of genotypes are evaluated in series of trials (environments) representing different levels of stress. The statistical analysis of the data from such trials concentrates on modelling the phenotypic behaviour of the genotypes across the set of environments. This phenotypic behaviour can be modelled in the form of genotype-specific linear and non-linear response curves in relation to environmental characterizations. Non-parallelism of the response curves indicates genotype × environment interaction. Identification of the genetic basis of the parameters determining the response curves will help in the development of breeding programmes for improving abiotic stress tolerance and understanding genotype × environment interaction. In this paper we present two strategies for locating quantitative trait loci for response-curve parameters and estimation of their allele effects. The procedures are ...
Genetic variation for environmental sensitivity indicates that animals are genetically different in their response to environmental factors. Environmental factors are either identifiable (e.g. temperature) and called macro-environmental or unknown and called micro-environmental. The objectives of this study were to develop a statistical method to estimate genetic parameters for macro- and micro-environmental sensitivities simultaneously, to investigate bias and precision of resulting estimates of genetic parameters and to develop and evaluate use of Akaikes information criterion using h-likelihood to select the best fitting model. We assumed that genetic variation in macro- and micro-environmental sensitivities is expressed as genetic variance in the slope of a linear reaction norm and environmental variance, respectively. A reaction norm model to estimate genetic variance for macro-environmental sensitivity was combined with a structural model for residual variance to estimate genetic variance for
An option into guide selection strategies in soybean breeding programs is to investigate associations between the main traits studied by breeders. A question that is faced is the possible influence of genotype x environment (GE) interactions on correlations among traits. Path analysis allows, in addition to measuring correlation, a more detailed study of cause / effect relationships among traits. We measured the effect of the GE interaction in the association between agronomic traits in soybeans. The experiments were carried out during two crop seasons, in three municipalities of Minas Gerais, Brazil, using a randomized complete blocks design, with 35 treatments. We evaluated number of grains, number of pods (NP), number of grains per pod, grain yield, weight of 100 grains, lodging score, plant height, height of first pod insertion, and full maturity. The data were submitted to variance analysis and path analysis. We also calculated the sum of ranks index in three ways, considering different ...
It has been suggested that climate change will lead to increased environmental fluctuations, which will undoubtedly have evolutionary consequences for all biota. For instance, fluctuations can directly increase the risk of invasions of alien species into new areas, as these species have repeatedly been proposed to benefit from disturbances. At the same time increased environmental fluctuations may also select for better invaders. However, selection by fluctuations may also influence the resistance of communities to invasions, which has rarely been tested. We tested eco-evolutionary dynamics of invasion with bacterial clones, evolved either in constant or fluctuating temperatures, and conducted experimental invasions in both conditions. We found clear evidence that ecological fluctuations, as well as adaptation to fluctuations by both the invader and community, all affected invasions, but played different roles at different stages of invasion. Ecological fluctuations clearly promoted invasions,
We have investigated patterns of selection and local adaptation in soil bacteria sampled over the course of 2 years. Our leading results are: (i) most variation in fitness in our dataset is explained by differences among genotypes, in comparison with environments or genotype-by-environment interactions; (ii) though small, G × E variation is significant, even among genotypes that would otherwise be identified as identical through conventional sequence analysis, and sufficient to generate strong divergent selection among the most disparate environments; (iii) temporal adaptation can be substantial, especially relative to spatial variation, and more complex than we would expect from simple models of directional selection. Below we discuss these observations and what they mean for understanding how selection works in natural communities of microbes.. The main effect of genotype contributed close to 70% of the variation in fitness in our experiment, dwarfing that contributed by the average effect of ...

Organisms adapt readily to regularly varying environments, for instance, by adjusting to the daily light cycles by using internal circadian clocks. Real problems arise when environmental fluctuations are irregular. Organisms can adapt to sudden changes in chemical composition, local temperature, or illumination by sensing the changes and responding appropriately, for example, by switching phenotype or behavior. But there is a cost: each individual must maintain active sensory machinery.. Population diversity offers an alternate way to adapt to randomly fluctuating environments. Different subsets of the total population may be well-adapted to different types of environments. In genetically clonal populations, phenotypic diversity is generated by stochastic phenotype-switching mechanisms (1-9). Examples include flagellin phase variation in Salmonella enterica (6); microsatellite length variation (slipped-strand mispairing), controlling the expression of contingency genes in Haemophilus influenzae ...
Studies of animals often report a greater sensitivity of one sex to poor rearing environments. However, it is unclear whether size differences associated with sex, sex itself, or other factors are responsible for differences in performance. While the greater nutritional requirement of the larger sex is a plausible explanation for increased sensitivity (i.e., size-dependent vulnerability), other hypotheses suggest that size-independent traits may have effects on the fitness of offspring (i.e., sex-dependent vulnerability). For example, the heterogametic sex may be more vulnerable to expression of sex-linked recessives in poor environments, or sex-specific phenotypes may have negative effects (e.g., increased testosterone in males). We examined support for these hypotheses through the use of meta-analytic techniques based on the published literature on avian species. Our results revealed small, nonsignificant effects for hypotheses of size- and sex-dependent susceptibilities alone. Application of a
Environmental Effects on the Enhancement in Natural and Damaged DNA Nucleobase Acidity Because of Discrete Hydrogen-Bonding Interactions
An enduring puzzle in evolutionary biology is to understand how individuals and populations adapt to fluctuating environments. Here we present an integro-differential model of adaptive dynamics in a phenotype-structured population whose fitness landscape evolves in time due to periodic environmental oscillations. The analytical tractability of our model allows for a systematic investigation of the relative contributions of heritable variations in gene expression, environmental changes and natural selection as drivers of phenotypic adaptation. We show that environmental fluctuations can induce the population to enter an unstable and fluctuation-driven epigenetic state. We demonstrate that this can trigger the emergence of oscillations in the size of the population, and we establish a full characterisation of such oscillations. Moreover, the results of our analyses provide a formal basis for the claim that higher rates of epimutations can bring about higher levels of intrapopulation heterogeneity, whilst

There are problems with a Si based biochemistry. First of all there dont seem to be commonly occurring catalytic reactions for manipulating Si here on earth, and they would be very useful to living organisms here on earth as Si is very common in the soil in various forms. Obviously there is a need for dramatically different conditions of temperature, pressure, or chemistry for Si life precursors to occur. Sensibly the most favorable conditions would need to be present in this experiment, as our one good example of a place where live developed seems to have very favorable conditions for the reactions that give rise to life (they occur with startling frequency which is why the apparatus was a success.) ...
SUMMARYFactors affecting survival of parasites introduced to new geographical regions include changes in environmental temperature. Protopolystoma xenopodis is a monogenean introduced with the amphibian Xenopus laevis from South Africa to Wales (probably in the 1960s) where low water temperatures impose major constraints on life-cycle processes. Effects were quantified by maintenance of eggs from infections in Wales under controlled conditions at 10, 12, 15, 18, 20 and 25°C. The threshold for egg viability/ development was 15°C. Mean times to hatching were 22 days at 25°C, 32 days at 20°C, extending to 66 days at 15°C. Field temperature records provided calibration of transmission schedules. Although egg production continues year-round, all eggs produced during ,8 months/ year die without hatching. Output contributing significantly to transmission is restricted to 10 weeks (May-mid-July). Host infection, beginning after a time lag of 8 weeks for egg development, is also restricted to 10 ...
Arguably, humans are in need of both better diagnostic tools to prevent pro- gression of diseases as well as greener catalysts for synthesis of chemicals.. Neurodegenerative diseases affecting neurons in the brain leads to demen- tias, where Alzheimers disease (AD) is the most prevalent. It is estimated that about 50 million people worldwide suffer from AD, a number that has more than doubled during the last 30 years. Currently, there is no cure for AD, but in order to slow the progression of symptoms it is crucial to develop biomarkers for early detection and initiation of clinical interventions.. With theoretical tools it is possible to better understand the optical prop- erties of fluorescent biomarkers, and thus contribute to steering the design of biomarkers for distinguishing different types of disease-associated proteins. Lu- minescent conjugated oligothiophenes (LCO) is a class of molecules that binds to aggregates of misfolded amyloid-β proteins, facilitating in vivo-detection of the ...

This review highlights current knowledge of environmental factors in carcinogenesis and their cellular targets. The hypothesis that environmental factors influence carcinogenesis is widely supported by both epidemiological and experimental studies. The fact that only a small fraction of cancers can be attributed to germline mutations in cancer-related genes further buttresses the importance of environmental factors in carcinogenesis. Furthermore, penetrance of germline mutations may be modified by either environmental or other genetic factors. Examples of environmental factors that have been associated with increased cancer risk in the human population include chemical and physical mutagens (e.g. cigarette smoke, heterocyclic amines, asbestos and UV irradiation), infection by certain viral or bacterial pathogens, and dietary non-genotoxic constituents (e.g. macro- and micronutrients). Among molecular targets of environmental influences on carcinogenesis are somatic mutation (genetic change) and ...
Genotype by environment interactions (GxE) may reduce accuracy of sire selection. The objectives of this study were to evaluate the presence of GxE by comparing reaction norms of bulls for birth weight, weaning weight, gain and stayability. Environments were defined as nine regions within the United States with similar temperature humidity index. The environmental mean was determined and a weighted regression was used to determine the progeny mean. Reaction norms were calculated by regressing the progeny mean on the environmental mean. A logit model was used to determine the heritability of stayability on the underlying scale. The heritabilities of BW and WW reaction norms were 0.40 and 0.39, respectively. Heritabilities of stayabaility were 0.34, 0.18, 0.19, 0.08, 0.09, 0.28, 0.30, 0.31 and 0.40 for regions C, D, G, L, M, N, P, S and U, respectively and 0.18 for the national dataset.

The strategic environmental assessment (SEA) is carried out for certain plans, programmes that are likely to have significant environmental effects in accordance with the SEA Act (200/2005) and the SEA Decree (347/2005). The purpose of SEA is to ensure that environmental considerations are integrated into plan and programme in support of environmentally sound and sustainable development. Environmental assessment means an assessment of the environmental effects of a plan or programme and its alternatives, preparation of an environmental report, carrying out consultations, taking into account the environmental report and the results of consultations in decisionmaking, and the provision of information on the decision. The SEA is made by the authority preparing the plan or programme. The types of plans and programmes subject to the SEA are mainly specified in the legislation. A SEA is a required for e.g. national land use objectives, nature conservation programmes, regional plans, river basin ...
Since plants not only provide food for man and his domestic animals but also pharmaceutical products and raw materials for industry, the development of new crops is of great importance. However, many plant species remain unexploited or are only utilized at a local level. This book provides information on the current research into the use of such crops and on their development in a commercial setting. Written by scientists from many different countries, it covers a wide variety of both temperate and tropical crops, their cultivation, marketing and development, and the socio-economic and environmental factors influencing their utilization.
In discussions regarding growth in specific populations, it is important to use measurements that are independent of important confounding variables such as age and sex. The growth pattern of Pima children markedly differs from U.S. references published by the CDC (14). Preliminary analysis of our data showed that age correlated with the CDC weight z score (r = 0.2, P , 0.01). Because we derived z scores from regression models fit to the study population, these scores had the desirable properties of a mean of zero, a standard deviation of one, and being uncorrelated with age or sex.. There has been considerable interest in identifying patterns of early growth associated with later development of type 2 diabetes. This reflects the potential that specific environmental factors influencing growth, for example undernutrition in fetal and early postnatal life, might predispose to later development of diabetes.. In Pima Indians, maternal diabetes is associated with an increased risk of both type 2 ...

Autonomous vehicle self-localization must be robust to environment changes, such as dynamic objects, variable illumination, and atmospheric conditions. Topological maps provide a concise representation of the world by only keeping information about relevant places, being robust to environment changes. On the other hand, semantic maps correspond to a high level representation of the environment that includes labels associated with relevant objects and places. Hence, the use of a topological map based on semantic information represents a robust and efficient solution for large-scale outdoor scenes for autonomous vehicles and Advanced Driver Assistance Systems (ADAS). In this work, a novel topological semantic mapping and localization methodology for large-scale outdoor scenarios for autonomous driving and ADAS applications is presented. The methodology uses: (i) a deep neural network for obtaining semantic observations of the environment, (ii) a Topological Semantic Map (TSM) for storing selected ...
Sanjay Jain (University of Delhi; SFI External Professor). Abstract. What sets the scale of the size of bacterial cells and the scale of fluctuations of cell size of genetically identical bacteria in a fixed environment? The talk will discuss the possible origin of these two scales, as well the origin of a time scale - the doubling time of cells. Phenotypic variation in genetically identical cells is generally believed to be a consequence of environmental variations or stochasticity in gene expression due to the small number of molecules involved. Another source of phenotypic variation will be described - the first passage time for a molecular population to cross a fixed threshold in growing cells. In the context of a generic class of mathematical models of cells it will be shown how this time scale and its fluctuations set the average size of cells and the fluctuations of size. ...

Survival is a key fitness component and the evolution of age- and stage-specific patterns in survival is a central question in evolutionary biology. In variable environments, favouring chances of survival at the expense of other fitness components could increase fitness by spreading risk across uncertain conditions, especially if environmental conditions improve in the future. Both the magnitude of environmental variation and temporal autocorrelation in the environment might therefore affect the evolution of survival patterns. Despite this, the influence of temporal autocorrelation on the evolution of survival patterns has not been addressed. Here, we use a trade-off structure which reflects the empirically inspired paradigm of acquisition and allocation of resources to investigate how the evolutionarily stable survival probability is shaped in variable, density-dependent environments. We show that temporal autocorrelation is likely to be an important aspect of environmental variability that contributes
Facets of the post-natal environment including the type and complexity of environmental stimuli, the quality of parenting behaviors, and the amount and type of stress experienced by a child affects brain and behavioral functioning. Poverty is a type of pervasive experience that is likely to influence biobehavioral processes because children developing in such environments often encounter high levels of stress and reduced environmental stimulation. This study explores the association between socioeconomic status and the hippocampus, a brain region involved in learning and memory that is known to be affected by stress. We employ a voxel-based morphometry analytic framework with region of interest drawing for structural brain images acquired from participants across the socioeconomic spectrum (n = 317). Children from lower income backgrounds had lower hippocampal gray matter density, a measure of volume. This finding is discussed in terms of disparities in education and health that are observed across the

Environmental factors can also raise your risk of addiction. For children and teens, lack of parental involvement can lead to greater risk-taking or experimentation with alcohol and other drugs. Young people who experience abuse or neglect from parents may also use drugs or alcohol to cope with their emotions.. Peer pressure is another risk factor for addiction, especially among young people. Even when its not overt or aggressive, pressure from friends to fit in can create an environment of experimentation with substances that can lead to addiction. The availability of a substance in your social group can also affect your risk of becoming addicted. For example, large amounts of alcohol are available in many social settings that are popular among college students.. If youre trying to recover from an addiction, you may need to avoid environmental triggers, including some activities, settings, or people. For example, you may need to avoid the people that you previously used drugs with. You may ...
Both diseases are so-called lifestyle diseases. From a global perspective, 370 million people suffer from diabetes and their number is rising. In the press, an epidemic of the third millennium is discussed. Over 15% of European couples of reproductive age have problems with conception of a child. The male factor accounts for over 60% in infertility. Infertility in men is caused by a wide range of factors - genetic and living environment, vascular disease but also metabolic illnesses. They include also diabetes mellitus.. From long-term studies, we know that environmental factors can have a negative effect on reproductive parameters in male mice. We were interested in whether the diabetes environment could have a similar effect, says Jana Pěknicová from the Laboratory of Reproductive Biology at the Institute of Biotechnology of the CAS - BIOCEV. In collaboration with Gabriela Pavlínková from the Laboratory of Molecular Pathogenetics, who has for a long time dealt with research of the ...

We design experiences that people love. Our innovation process brings together superior design, engineering and consumer insights to build a diverse and growing portfolio. We believe we must find ways to make electronics more "cradle to cradle." A product that is created (from a cradle of materials) should contribute to society over its entire lifecycle, and the materials that form part of that product should be recycled to form inputs for other products at end-of-life. Its not easy. We believe that if we collectively focus efforts, creativity, and innovation in that direction we can achieve this sooner than we might think.. ...

DOSIS 3D helps to understand space radiation and how it penetrates the Space Station walls. Active and passive radiation detectors are used to map radiation in all modules of the Space Station.. The European Columbus laboratory is monitored by 11 passive dosimeters. The dosimeters are about the size of a pack of playing cards and attached to the walls of Columbus with Velcro. The detectors record how much radiation has been absorbed in total during the period they are in space.. After each six-month crew rotation, the detectors are replaced to record changes in radiation. Luca removed an old set of dosimeters from Columbus, packed them for return to Earth, and stuck a new set to the walls.. In addition to the passive detectors, DOSIS-3D uses active dosimeters that measure fluctuations in radiation levels over time. Data from all Station partners is shared to create as complete a picture of space radiation as possible.. ...
