Effects of rotational and continuous grazing on herbage quality, feed intake and performance of sheep on a semi-arid grassland steppe.
Abstract Compared to continuous grazing (CG), rotational grazing (RG) increases herbage production and thereby the resilience of grasslands to intensive grazing. Results on feed intake and animal performance, however, are contradictory. Hence, the objective of the study was to determine the effects of RG and CG on herbage mass, digestibility of ingested organic matter (dOM), organic matter intake (OMI) and live weight gain (LWG) of sheep in the Inner Mongolian steppe, China. During June-September 2005-2008, two 2-ha plots were used for each grazing system. In RG, plots were divided into four 0.5-ha paddocks that we...

Projecting Thailand physician supplies between 2012 and 2030: application of cohort approaches
Conclusion: This supply forecast, given various assumptions, would meet the targets outlined above, ofone doctor per 1,800 population, and one per 1,500 population, by 2016 and 2020respectively. However, rapid changes in the contextual environment, e.g. economic demand,physician demographics, and disease burden, may mean that the annual loss rate of 1% usedin this projection is not accurate in the future. To ensure population health needs are met,parallel policies on physician production encompassing both qualitative and quantitativeaspects should be in place.

DANPOS: Dynamic analysis of nucleosome position and occupancy by sequencing [METHOD]
Recent developments in next-generation sequencing have enabled whole-genome profiling of nucleosome organizations. Although several algorithms for inferring nucleosome position from a single experimental condition have been available, it remains a challenge to accurately define dynamic nucleosomes associated with environmental changes. Here, we report a comprehensive bioinformatics pipeline, DANPOS, explicitly designed for dynamic nucleosome analysis at single-nucleotide resolution. Using both simulated and real nucleosome data, we demonstrated that bias correction in preliminary data processing and optimal statistical tes...

Intercoalescence Time Distribution of Incomplete Gene Genealogies in Temporally Varying Populations, and Applications in Population Genetic Inference
Summary Tracing back to a specific time T in the past, the genealogy of a sample of haplotypes may not have reached their common ancestor and may leave m lineages extant. For such an incomplete genealogy truncated at a specific time T in the past, the distribution and expectation of the intercoalescence times conditional on T are derived in an exact form in this paper for populations of deterministically time‐varying sizes, specifically, for populations growing exponentially. The derived intercoalescence time distribution can be integrated to the coalescent‐based joint allele frequency spectrum (JAFS) theory, and is us...

Macrophage/epithelial cell CCL2 contributes to rhinovirus-induced hyperresponsiveness and inflammation in a mouse model of allergic airways disease
Human rhinovirus (HRV) infections lead to exacerbations of lower airways disease in asthmatic patients but not in healthy individuals. However, underlying mechanisms remain to be completely elucidated. We hypothesized that the Th2-driven allergic environment enhances HRV-induced CC chemokine production, leading to asthma exacerbations. Ovalbumin (OVA)-sensitized and -challenged mice inoculated with HRV showed significant increases in the expression of lung CC chemokine ligand (CCL)-2/monocyte chemotactic protein (MCP)-1, CCL4/macrophage inflammatory protein (MIP)-1β, CCL7/MCP-3, CCL19/MIP-3β, and CCL20/MIP3&alpha...

Lifestyle change in Kerala, India: needs assessment and planning for a community-based diabetes prevention trial. K-DPP Needs Assessment
Conclusion: These findings provide strong support for undertaking more research into the conduct of community-based diabetes prevention in the rural areas of Kerala. We aim to develop, implement and evaluate a group-based peer support program that will address cultural and family determinants of lifestyle risks, including family decision-making regarding adoption of healthy dietary and physical activity patterns. Furthermore, we believe that this approach will be feasible, acceptable and effective in these communities; with the potential for scale-up in other parts of India.

Replication of a carcinogenic nitropyrene DNA lesion by human Y-family DNA polymerase
Nitrated polycyclic aromatic hydrocarbons are common environmental pollutants, of which many are mutagenic and carcinogenic. 1-Nitropyrene is the most abundant nitrated polycyclic aromatic hydrocarbon, which causes DNA damage and is carcinogenic in experimental animals. Error-prone translesion synthesis of 1-nitropyrene–derived DNA lesions generates mutations that likely play a role in the etiology of cancer. Here, we report two crystal structures of the human Y-family DNA polymerase iota complexed with the major 1-nitropyrene DNA lesion at the insertion stage, incorporating either dCTP or dATP nucleotide opposite th...

The relationship between physical activity, physical fitness and overweight in adolescents: a systematic review of studies published in or after 2000
Conclusions: The small number of studies on the interrelationship of BMI, fitness and physical activity emphasizes the need for longitudinal studies that would reveal 1) the causality between physical activity and overweight / fitness and overweight and 2) the causal interrelationships among overweight, physical activity and fitness. These results must be carefully interpreted given the lack of distinction between self-reported and objective physical activity and that studies analyzing the metabolic syndrome or cardiovascular disease were not considered. The importance of physical activity or fitness in predicting overweight remains unknown.

The Science of Early Life Toxic Stress for Pediatric Practice and Advocacy
In this report, we provide an overview of the science of toxic stress. We summarize the development of the neuroendocrine-immune network, how its function is altered by early life adversity, and how these alterations then increase vulnerability to disease. The fact that early environments shape and calibrate the functioning of biological systems very early in life is both a cautionary tale about overlooking critical periods in development and reason for optimism about the promise of intervention. Even in the most extreme cases of adversity, well-timed changes to children’s environments can improve outcomes. Pediatric...

Prehypertension and Hypertension in Community-Based Pediatric Practice
Prevalence of hypertension in children increased significantly over the past few decades, tracks into adulthood, and is a major risk factor for cardiovascular disease. However, current prevalence estimates in children have largely been based on studies conducted in school environments. The current study reports the prevalence of childhood hypertension in community pediatric practice, which provides a typical pediatric examination environment, unlike blood pressure measured in school. The results show a significantly lower prevalence than what has previously been reported. (Read the full article)

Understanding the Moral Nature of Intrapartum Nursing
ConclusionThese findings suggest a need to challenge assumptions related to the provision of choice and family centered care to create environments that can support and sustain understanding and trust between nurses and women giving birth. In addition, given the lack of shared understandings of what constitutes best care, there is a need to develop collaborative models of care that include the voices of women as a central component.

Updating of the spatial reference frame of head direction cells in response to locomotion in the vertical plane
Many species navigate in three dimensions and are required to maintain accurate orientation while moving in an Earth vertical plane. Here we explored how head direction (HD) cells in the rat anterodorsal thalamus responded when rats locomoted along a 360° spiral track that was positioned vertically within the room at the N, S, E, or W location. Animals were introduced into the vertical plane either through passive placement (experiment 1) or by allowing them to run up a 45° ramp from the floor to the vertically positioned platform (experiment 2). In both experiments HD cells maintained direction-specific firing in ...

The effect of larval nutritional deprivation on the life history and DDT resistance phenotype in laboratory strains of the malaria vector Anopheles arabiensis
The 'silver spoon' hypothesis of larval nutrition in insects suggests that well nourished larvae become healthier adults that are better capable of survival in variable environments, particularly are more likely to be resistant to insecticides. This paper shows how this operates in an important vector of malaria.

Reviewing the definition of crisis in dementia care
Conclusions: This is the first article to review the definition of crisis in the context of dementia care. A review of the literature indicated that the definition of a crisis is idiosyncratic. Therefore, it is difficult to prevent or plan for all crises. We used an operational framework to compile types of crisis stressors and recommendations from the crisis literature based on three different perspectives; the person with the dementia, the caregiver and the healthcare providers.

IgE cross-linking critically impairs human monocyte function by blocking phagocytosis
Conclusions: IgE cross-linking drives monocyte proinflammatory processes and autoregulatory IL-10 in a serum IgE-dependent manner. In contrast, monocyte phagocytic function is critically impaired by IgE cross-linking. Our findings suggest that IgE cross-linking on monocytes may contribute to allergic disease by both enhancing detrimental inflammatory responses and concomitantly crippling phagocytosis, a primary mechanism used by these cells to resolve inflammation.

The cutaneous innate immune response in patients with atopic dermatitis
Orchestrating when and how the cutaneous innate immune system should respond to commensal or pathogenic microbes is a critical function of the epithelium. The cutaneous innate immune system is a key determinant of the physical, chemical, microbial, and immunologic barrier functions of the epidermis. A malfunction in this system can lead to an inadequate host response to a pathogen or a persistent inflammatory state. Atopic dermatitis is the most common inflammatory skin disorder and characterized by abnormalities in both skin barrier structures (stratum corneum and tight junctions), a robust TH2 response to environmental ...

Exposure to environmental allergens can result in apoptosis of airway epithelial cells, and clusters of apoptotic cells can be found in the sputum of asthmatic patients, but the significance of the clearance of apoptotic cells by epithelial cells themselves is unknown. Juncadella et al (Nature 2012 [Epub ahead of print]) investigated the phagocytic activity of airway epithelial cells in experimental models of asthma. Pulmonary epithelial cells were shown to engulf apoptotic cells by means of a mechanism that was dependent on recognition of phosphatidylserine on the surfaces of the apoptotic cells and Rac1 expression by the...

Fungal diversity from various marine habitats deduced through culture‐independent studies
Abstract Studies on the molecular diversity of the micro‐eukaryotic community have shown that fungi occupy a central position in a large number of marine habitats. Environmental surveys using molecular tools have shown the presence of fungi from a large number of marine habitats such as deep‐sea habitats, pelagic waters, coastal regions, hydrothermal vent ecosystem, anoxic habitats and ice‐cold regions. This is of interest to a variety of research disciplines like ecology, evolution, biogeochemistry and biotechnology. In this review we have summarized how molecular tools, have helped to broaden our understanding of t...

Assisted reproductive technologies and perinatal morbidity: interrogating the association
Interrogating the association between assisted reproductive technologies (ART) and perinatal outcome is complicated but very important. This is an introduction to a series of articles that review this potential association with an eye toward etiology of risk, and what aspects of in vitro fertilization (IVF) can be modified to reduce this risk. When an association is not due to chance (i.e., statistically significant), one must also consider how the association may be affected due to bias or confounding. Despite lack of the perfect study, perinatal consequences of ART are apparent, even though the vast majority of children...

Heavy Metal Associated Isoprenylated Plant Protein (HIPP): characterization of a family of proteins exclusive of plants
In this study, we provided evidence that proteins of this family are found only in vascular plants and can be separated into five distinct clusters. HIPPs may be involved in (i) heavy metal homeostasis and detoxification mechanisms, especially those involved in cadmium tolerance; (ii) transcriptional responses to cold and drought, and (iii) plantpathogen interactions. In particular, our results identified that the rice (Oryza sativa) HIPP OsHIPP41 gene is highly expressed in response to cold and drought stresses and its product is localized in the cytosol and the nucleus.
