    The prevalence of low birth weight (LBW) in Indonesia varied between 2.1 - 17.2%. At the end of Five years Development Plan V (Repelita V) it was 15.0%, and is expected to decrease to 10.0% by the end of Repelita VI. Low Birth Weight infant (less than 2500 grm) is an important issue, because of its relationship with the survival and health status of the infant in the future. The prevalence of anemia in pregnant women is 63.5%. The cause of anemia is mostly iron deficiency. The need of iron in pregnant women is quite high which is an average of 800 mg during pregnancy. Daily food contains 10 - 20 mg iron but the human body can absorb only less than 10.0%. To overcome the problem, iron pills distribution program is implemented. The iron pills contain 200 mg ferro sulfate and 0.25 mg folic acid, and are given to all pregnant women who visit Community Health Centres (Puskesmas) and Integrated Health Service Posts (Posyandu). Each pregnant women is expected to have at least 90 iron pills during the pregnancy. The objective of further analysis of the Demographic and Health Survey 1994 is to obtain information on the impact of iron pills on low birth weight. Among the 1689 weighted children born in 1994, there were 6.7% (112 children) with low birth weight. The percentage of low birth weight (10.6%) in the mothers who did not take the iron pills is the highest, followed by mothers who took less than 90 pills (6.0%) and the lowest percentage of low birth weight is found among mothers who took the least iron pills (5.9%), and statistically the difference is significant at p=0.0271. Among mothers who weighted their new born children, 14.6% did not take iron pills during pregnancy, only 26.1% mothers who took at least 90 iron pills during pregnancy. There is variation among the number of iron pills taken. Iron pill is useful for pregnant women. Based on the pills consumed by the pregnant women, the risk for having low birth weight infant for mother who did not take pills compared with those who take at least 90 pills is 3.5 times (95% CI: 1.41 - 9.09) in Java Bali, 10.3 times (95% CI: 1.11-14.29) for mothers with education Junior High School and 2.7 times (95% CI: 1.11 - 6.66) for mothers who give birth for the first child.Based on the number of pills taken by pregnant women, risk for Low Birth Weight in urban and rural area is not different, in Java Bali and as outer Java Bali. To reduce the Low Birth Weght, it is important to intensify monitoring, educating, informating on the importance of iron pills with balanced nutrition through health attendant and community key person and involvement of private company through mass media. It is important to have examination of women before she get pregnant and give proper treatment to the diseases which can worsen the anemia during pregnancy. It is also important to do special research on the high risk of anemia by considerating factors which determine low birth weight in the effort of promoting the health of pregnant women and the infants, so that specific and or appropriate methods of intervention can be developed and applied

    An “orientation sphere” visualization for examining animal head movements

    Animal behavior is elicited, in part, in response to external conditions, but understanding how animals perceive the environment and make the decisions that bring about these behavioral responses is challenging. Animal heads often move during specific behaviors and, additionally, typically have sensory systems (notably vision, smell, and hearing) sampling in defined arcs (normally to the front of their heads). As such, head‐mounted electronic sensors consisting of accelerometers and magnetometers, which can be used to determine the movement and directionality of animal heads (where head “movement” is defined here as changes in heading [azimuth] and/or pitch [elevation angle]), can potentially provide information both on behaviors in general and also clarify which parts of the environment the animals might be prioritizing (“environmental framing”). We propose a new approach to visualize the data of such head‐mounted tags that combines the instantaneous outputs of head heading and pitch in a single intuitive spherical plot. This sphere has magnetic heading denoted by “longitude” position and head pitch by “latitude” on this “orientation sphere” (O‐sphere). We construct the O‐sphere for the head rotations of a number of vertebrates with contrasting body shape and ecology (oryx, sheep, tortoises, and turtles), illustrating various behaviors, including foraging, walking, and environmental scanning. We also propose correcting head orientations for body orientations to highlight specific heading‐independent head rotation, and propose the derivation of O‐sphere‐metrics, such as angular speed across the sphere. This should help identify the functions of various head behaviors. Visualizations of the O‐sphere provide an intuitive representation of animal behavior manifest via head orientation and rotation. This has ramifications for quantifying and understanding behaviors ranging from navigation through vigilance to feeding and, when used in tandem with body movement, should provide an important link between perception of the environment and response to it in free‐ranging animals.Deanship of Scientific Research at the King Saud University through Vice Deanship of Research Chairs; The National Geographic Global Exploration Fund.

    Health-enhancing potential bioactive peptide (BP) has driven an interest in food proteins as well as in the development of predictive methods. Research in this area has been especially active to use them as components in functional foods. Apparently, BPs do not have a given biological function in the containing proteins and they do not evolve under independent evolutionary constraints. In this work we performed a large-scale mapping of BPs in sequence and structural space. Using well curated BP deposited in BIOPEP database, we searched for exact matches in non-redundant sequences databases. Proteins containing BPs, were used in fold-recognition methods to predict the corresponding folds and BPs occurrences were mapped. We found that fold distribution of BP occurrences possibly reflects sequence relative abundance in databases. However, we also found that proteins with 5 or more than 5 BP in their sequences correspond to well populated protein folds, called superfolds. Also, we found that in well populated superfamilies, BPs tend to adopt similar locations in the protein fold, suggesting the existence of hotspots. We think that our results could contribute to the development of new bioinformatics pipeline to improve BP detection.Fil: Nardo, Agustina Estefania. Provincia de Buenos Aires. Gobernación.

    Large-scale patterns of turnover and basal area change in Andean forests

    General patterns of forest dynamics and productivity in the Andes Mountains are poorly characterized. Here we present the first large-scale study of Andean forest dynamics using a set of 63 permanent forest plots assembled over the past two decades. In the North-Central Andes tree turnover (mortality and recruitment) and tree growth declined with increasing elevation and decreasing temperature. In addition, basal area increased in Lower Montane Moist Forests but did not change in Higher Montane Humid Forests. However, at higher elevations the lack of net basal area change and excess of mortality over recruitment suggests negative environmental impacts. In North-Western Argentina, forest dynamics appear to be influenced by land use history in addition to environmental variation. Taken together, our results indicate that combinations of abiotic and biotic factors that vary across elevation gradients are important determinants of tree turnover and productivity in the Andes. More extensive and longer-term monitoring and analyses of forest dynamics in permanent plots will be necessary to understand how demographic processes and woody biomass are responding to changing environmental conditions along elevation gradients through this century

    Drosophila Genome-Wide RNAi Screen Identifies Multiple Regulators of HIF–Dependent Transcription in Hypoxia

    Hypoxia-inducible factors (HIFs) are a family of evolutionary conserved alpha-beta heterodimeric transcription factors that induce a wide range of genes in response to low oxygen tension. Molecular mechanisms that mediate oxygen-dependent HIF regulation operate at the level of the alpha subunit, controlling protein stability, subcellular localization, and transcriptional coactivator recruitment. We have conducted an unbiased genome-wide RNA interference (RNAi) screen in Drosophila cells aimed to the identification of genes required for HIF activity. After 3 rounds of selection, 30 genes emerged as critical HIF regulators in hypoxia, most of which had not been previously associated with HIF biology. The list of genes includes components of chromatin remodeling complexes, transcription elongation factors, and translational regulators. One remarkable hit was the argonaute 1 (ago1) gene, a central element of the microRNA (miRNA) translational silencing machinery. Further studies confirmed the physiological role of the miRNA machinery in HIF–dependent transcription. This study reveals the occurrence of novel mechanisms of HIF regulation, which might contribute to developing novel strategies for therapeutic intervention of HIF–related pathologies, including heart attack, cancer, and stroke

    Plant trait and vegetation data along a 1314 m elevation gradient with fire history in Puna grasslands, Perú

    Alpine grassland vegetation supports globally important biodiversity and ecosystems that are increasingly threatened by climate warming and other environmental changes. Trait-based approaches can support understanding of vegetation responses to global change drivers and consequences for ecosystem functioning. In six sites along a 1314 m elevational gradient in Puna grasslands in the Peruvian Andes, we collected datasets on vascular plant composition, plant functional traits, biomass, ecosystem fluxes, and climate data over three years. The data were collected in the wet and dry season and from plots with different fire histories. We selected traits associated with plant resource use, growth, and life history strategies (leaf area, leaf dry/wet mass, leaf thickness, specific leaf area, leaf dry matter content, leaf C, N, P content, C and N isotopes). The trait dataset contains 3,665 plant records from 145 taxa, 54,036 trait measurements (increasing the trait data coverage of the regional flora by 420%) covering 14 traits and 121 plant taxa (ca. 40% of which have no previous publicly available trait data) across 33 families
