Dietary elimination of children with food protein induced gastrointestinal allergy – micronutrient adequacy with and without a hypoallergenic formula?

Background: The cornerstone for management of Food protein-induced gastrointestinal allergy (FPGIA) is dietary exclusion; however the micronutrient intake of this population has been poorly studied. We set out to determine the dietary intake of children on an elimination diet for this food allergy and hypothesised that the type of elimination diet and the presence of a hypoallergenic formula (HF) significantly impacts on micronutrient intake. Method: A prospective observational study was conducted on children diagnosed with FPIGA on an exclusion diet who completed a 3 day semi-quantitative food diary 4 weeks after commencing the diet. Nutritional intake where HF was used was compared to those without HF, with or without a vitamin and mineral supplement (VMS). Results: One-hundred-and-five food diaries were included in the data analysis: 70 boys (66.7%) with median age of 21.8 months [IQR: 10 - 67.7]. Fifty-three children (50.5%) consumed a HF and the volume of consumption was correlated to micronutrient intake. Significantly (p <0.05) more children reached their micronutrient requirements if a HF was consumed. In those without a HF, some continued not to achieve requirements in particular for vitamin D and zinc, in spite of VMS. Conclusion: This study points towards the important micronutrient contribution of a HF in children with FPIGA. Children, who are not on a HF and without a VMS, are at increased risk of low intakes in particular vitamin D and zinc. Further studies need to be performed, to assess whether dietary intake translates into actual biological deficiencies

Karakteristik Pantai Pulau Laut-sekatung (Salah Satu Pulau Terluar Nkri)

Pulau Laut-Sekatung adalah salah satu pulau terluar Negara Republik Indonesia yang berbatasan dengan perairan Malaysia Timur. Pulau ini terletak di laut Cina Selatan sebagai bagian dari Kepulauan Natuna dan secara administratif termasuk Provinsi Kepulauan Riau. Tujuan dari studi ini adalah untuk mengetahui karakteristik dan tipologi kawasan pantai berdasarkan metoda geologi dan geofisika kelautan seperti pemetaan geologi kawasan pantai, pengambilan contoh sedimen, serta data-data penunjang seperti pengamatan pasang surut, pengukuran arus dan batimetri. Berdasarkan metoda-metoda tersebut, kawasan pantai Pulau Laut dapat dibedakan 3 jenis yaitu, pantai berpasir, pantai berbatuan dan pantai berbakau. Pantai tipe I adalah pantai berpasir menempati bagian selatan dan timur daerah penelitian, merupakan pasir hasil metasedimen dan terumbu karang. Pantai tipe II adalah pantai berbakau, menempati bagian tenggara daerah penelitian dan merupakan endapan rawa dengan morfologi pedarataran.

Tipe pasang surut di perairan Pulau Laut-Sekatung adalah harian tunggal (diurnal tide). Morfologi dasar laut perairan pantai sebelah barat dan timur berbeda, dimana sebelah barat dari garis pantai morfologinya curam sedangkan sebelah timur morfologinya landai. Perubahan garis pantai dicirikan oleh erosi pantai dibagian barat dan akrasi dibagian timur. Kata kunci: Pulau Laut-Sekatung, pulau terluar, karakteristik pantai The Sekatung-Laut Island is one of the outer island of the Republic Indonesia which bordered with the East of Malaysia waters. This island is located in the South China Sea as part of Natuna island and administratively within the Province of Riau islands. The purpose of this study is to know the characteristic and typology of coastal area. To support this purpose, the geology and geophysical survey method such as coastal mapping, sediment sampling, tide, current and bathymetry measurement have been done. Based on these method, the coastal area of Sekatung-Sea island can be distinguished in to 3 type. Coastal type I is a sand coast which is located in the south and east of the island where sand material is derived from meta-sediment rock and coral reef. Coastal type II is a mangrove coast which is located in the south east of study area. This coast is characterized by swamp deposits, mangrove plantation and plain area. Coastal type III is a rocky coast. This coast is characterized by the steep cliff of Cretaceous meta-sediment and volcanic rock of Bungaran Formation. Tide characteristic of study area is diurnal tide and the maximum current velocity is about 1.6 meter/second and is dominated by north direction. The morphology of water coast at west coast is very steep and in the eastern part is very flat. The coast line change is characterized by the erosion in the eastern part and akrasi to sable coast in the western part. Key words: Laut-Sekatung island, outer island, coastal characteristi

Detection of Non-Random Galaxy Orientations in X-ray Subclusters of the Coma Cluster

This study on the Coma cluster suggests that there are deviations from a completely random galaxy orientation on small scales. Since we found a significant coincidence of hot-gas features identified in the latest X-ray observations of Coma with these local anisotropies, they may indicate regions of recent mutual interaction of member galaxies within subclusters which are currently falling in on the main cluster.Comment: 4 pages, 4 figures, 3 tables v2: Rewritten introduction, amendments to the 'Interpretation' sectio

Penafsiran Struktur Geologi Bawah Permukaan Di Kawasan Semburan Lumpur Sidoarjo, Berdasarkan Penampang Ground Penetrating Radar (GPR)

DOI: 10.17014/ijog.v5i3.102The Ground Penetrating Radar (GPR) survey has been carried out around the Sidoarjo mud eruption. The aim of the survey is to see how far the development of shallow subsurface geological condition related to the eruptions that frequently occur around the main eruption. Ground Probing Radar is one of the geophysical method which is developed as a tool for a relatively shallow and detailed subsurface geological survey. The use of GPR method is not different with the seismic reflection method. The penetration depth of GPR method depends on electric properties of subsurface geological condition such as electric conductivity and dielectric constant. Both of these properties are related to physical properties of soil or rock such as water content and salinity. The result of the survey shows that at a shallow depth the geological structure such as fold, fault, and joint is frequently seen. Based on these results, the GPR method is very useful to decide the indication of potential area of small mud intrusion, so that the result can be used to help the mitigation plan

An Economic analysis of the potential for precision farming in UK cereal production

The results from alternative spatial nitrogen application studies are analysed in economic terms and compared to the costs of precision farming hardware, software and other services for cereal crops in the UK. At current prices, the benefits of variable rate application of nitrogen exceed the returns from a uniform application by an average of £22 ha−1 The cost of the precision farming systems range from £5 to £18 ha−1 depending upon the system chosen for an area of 250 ha. The benefits outweigh the associated costs for cereal farms in excess of 80 ha for the lowest price system to 200–300 ha for the more sophisticated systems. The scale of benefits obtained depends upon the magnitude of the response to the treatment and the proportion of the field that will respond. To be cost effective, a farmed area of 250 ha of cereals, where 30% of the area will respond to variable treatment, requires an increase in crop yield in the responsive areas of between 0·25 and 1.00 t ha−1 (at £65 t−1) for the basic and most expensive precision farming systems, respectively

Subsurface Geological Condition of Several Land Coastal Zone in Indonesia Based on the Gssi Ground Probing Radar (Gpr) Record Interpretation

The GSSI Ground Penetrating radar have been used to profile the shallow depth of subsurface geology of several area of Land Coastal zone in Indonesia Analysis of a large data base of GPR profile from natural subsurface geological condition along the land coast line have allowed identification of reflection configuration that characterize this type of sub surface geological environment. In many contamination problem, the geological information of coastal area is sparse and drill-core description only gives a limited picture of the geometry of inhomogeneties. The Ground-Probing Radar (GPR) method is a promising tool for resolving changes of physical properties in subsurface geological condition at the scale of natural inhomogeneties arising from changing lithology composition. The objective of present work are to examine whether and to what extent the characteristic lithofacies of subsurface lithology can be recognised as mapable reflection pattern on ground probing radar (GPR) reflection profiles in order to gain information about the subsurface geometry of subsurface geology in coastal area.

Multiaperture UBVRIzJHKUBVRIzJHK Photometry of Galaxies in the Coma Cluster

We present a set of $UBVRIzJHK_s$ photometry for 745 $J+H$ band selected objects in a $22.5' \times 29.2'$ region centered on the core of the Coma cluster. This includes 516 galaxies and is at least 80% complete to H=16, with a spectroscopically complete sample of 111 cluster members (nearly all with morphological classification) for $H < 14.5$. For each object we present total \cite{kron80} magnitudes and aperture photometry. As an example, we use these data to derive color-magnitude relations for Coma early-type galaxies, measure the intrinsic scatter of these relations and its dependence on galaxy mass, and address the issue of color gradients. We find that the color gradients are mild and that the intrinsic scatter about the color-magnitude relation is small ($\sim 0.05$ mag in $U-V$ and less than $\sim 0.03$ in $B-R$, $V-I$ or $J-K$). There is no evidence that the intrinsic scatter varies with galaxy luminosity, suggesting that the cluster red sequence is established at early epochs over a range of $\sim 100$ in stellar mass.Comment: 41 pages, 5 figures, 18 data tables attached to source files or available on request from R.

A comparison of the galaxy populations in the Coma and distant clusters: the evolution of k+a galaxies and the role of the intracluster medium

The spectroscopic properties of galaxies in the Coma cluster are compared with those of galaxies in rich clusters at $z \sim 0.5$, to investigate the evolution of the star formation history in clusters. Luminous galaxies with $M_V \leq -20$ and post-starburst/post-starforming (k+a) spectra which constitute a significant fraction of galaxies in distant cluster samples are absent in Coma, where spectacular cases of k+a spectra are found instead at $M_V>-18.5$ and represent a significant proportion of the cluster dwarf galaxy population. A simple inspection of their positions on the sky indicates that this type of galaxy does not show a preferential location within the cluster, but the bluest and strongest-lined group of k+a's lies in projection towards the central 1.4 Mpc of Coma and have radial velocities significantly higher than the cluster mean. We find a striking correlation between the positions of these young and strong post-starburst galaxies and substructure in the hot intracluster medium (ICM) identified from {\it XMM-Newton} data, with these galaxies lying close to the edges of two infalling substructures. This result strongly suggests that the interaction with the dense ICM could be responsible for the quenching of the star formation (thus creating the k+a spectrum), and possibly, for any previous starburst. The evolution with redshift of the luminosity distribution of k+a galaxies can be explained by a ``downsizing effect'', with the maximum luminosity/mass of actively star-forming galaxies infalling onto clusters decreasing at lower redshift. We discuss the possible physical origin of this downsizing effect and the implications of our results for current scenarios of environmental effects on the star formation in galaxies.Comment: 21 pages, 7 figures, to appear in ApJ, version after referee's change
