Background Previous studies have shown an effect of lysine fortification on nutrition and immunity of poor men, women, and children consuming a predominantly wheat-based diet. Objective To examine the lysine value of diets and the effect of lysine fortification on functional protein status, anthropometry, and morbidity of men, women, and children in rural Syria. Methods At baseline of a two-phase study using 7-day household food intake inventories ( n = 98), nutrient availabilities per adult male equivalent were estimated. In the intervention phase, a 16-week double-blind trial, households ( n = 106) were randomly assigned to control and lysine groups. Hematologic and anthropometric data were collected from men ( n = 69; 31 control, 38 lysine), women ( n = 99; 51 control, 48 lysine), and children ( n = 69; 37 control, 32 lysine) at baseline, 12 weeks, and 16 weeks. Total CD3 T lymphocytes as well as T lymphocytes bearing the receptors CD4, CD8, and CD56, IgM, IgG, IgA, complement C3, C-reactive protein, serum albumin, prealbumin, transferrin, retinol-binding protein, hemoglobin, and hepatitis B surface antigen were determined. Health status and flour usage were monitored. Paired- and independent-sample t-tests and chi-square tests were performed. Results Mean nutrient availability per adult equivalent was 2,650 ± 806 kcal, 70.1 ± 26.4 g protein, 65 ± 14% cereal protein, and 41.9 ± 0.8 mg lysine per gram of protein. Complement C3 was significantly higher in men receiving lysine than in controls ( p < .05). Among women, there were significant differences between the control and lysine groups in diarrhea period prevalence (total number of diarrheal episodes during the period of intervention divided by the total number of observations), (20 in the control group, 6 in the lysine group; p = .014), the mean number of days ill (0.4 ± 0.7, control, 0.14 ± 0.4, lysine, p = 0.03), and the number of diarrheal episodes per person per year (1.39 in the control group, 0.47 in the lysine group). No other significant differences between the lysine and the control groups were observed. Conclusions Lysine fortification of wheat flour demonstrated a positive effect on diarrheal morbidity in women. The effect could be attributed to an improvement in protein utilization but possibly also to a direct effect of lysine in gastrointestinal tract. Studies in populations with higher diarrheal prevalence and significant dietary lysine deficiency are needed to determine whether the reported effects on diarrheal prevalence are replicable and whether they are pharmacological or nutritional. It would be particularly desirable to study the effect of lysine on diarrhea in preschool children, who have much higher morbidity and mortality rates from this disease than school-age children or adults.
Seasonality, Household Food Security, and Nutritional Status in Dinajpur, Bangladesh
Authors: Hillbruner Chris , Egan Rebecca 
Published: August 2015

Background The influence of seasonality on food security and nutritional status is widely accepted. However, research has typically focused on rural households and has not explored the specific mechanisms underlying seasonal effects. Objective To investigate the role of seasonality in determining the food security and nutritional status of low-income urban households and to isolate specific pathways through which seasonality has its impact. Methods Secondary panel data from CARE/IFPRI were utilized. Three rounds of data were collected from approximately 600 households in low-income areas of Dinajpur, Bangladesh, from 2002 through 2003, twice during the monsoon season and once in the dry season. Household-level surveys collected data on income and expenditure, employment, urban agriculture, health, and assets. Height and weight measurements were taken from children between the ages of 6 and 72 months. Paired t-tests and logistic fixed-effects modeling were then used to explore the role of seasonality. Results The prevalence rates of food insecurity, wasting, and inadequate growth were all significantly higher during the monsoon season as compared with the dry season. Dietary diversity and lost work due to the weather were identified as specific pathways through which season affected household food security. However, mechanisms hypothesized to contribute to seasonal declines in nutritional status, such as child illness, were not found to be significant. Conclusions Season had a significant effect on both food security and nutritional status in Dinajpur, with households consistently worse off during the monsoon season. Initiatives to promote food market development, support employment during the hunger season, and prevent seasonal declines in nutritional status should be implemented.

AbstractFlamite (Ca,Na,K)2(Si,P)O4 (P63; a = 43.3726(18), c = 6.8270(4) Å; V = 11122.2(9) Å3), a natural analogue of the P,Na,K-doped high-temperature α-Ca2SiO4 modification, is a new mineral from Ca- and Al-rich paralava, an ultrahigh-temperature combustion metamorphic melt rock. The type locality is situated in the southern Hatrurim Basin, the Negev Desert, Israel. Flamite occurs as regular lamellar intergrowths with partially hydrated larnite, together with rock-forming gehlenite, rankinite and Ti-rich andradite, minor ferrian perovskite, magnesioferrite, hematite, and retrograde ettringite and calcium silicate hydrates. The mineral is greyish to yellowish, transparent with a vitreous lustre, non-fluorescent under ultraviolet light and shows no parting or cleavage; Mohs hardness is 5–5½; calculated density is 3.264 g cm–3. The empirical formula of holotype flamite (mean of 21 analyses) is (Ca1.82Na0.09K0.06(Mg,Fe,Sr,Ba)0.02)Σ1.99(Si0.82P0.18)Σ1.00O4. The strongest lines in the powder X-ray diffraction pattern are [d, Å (Iobs)]: 2.713(100), 2.765(44), 2.759(42), 1.762(32), 2.518(29), 2.402(23), 2.897(19), 1.967(18), 2.220(15), 1.813(15).

Gatedalite, Zr(Mn2+2Mn3+4)SiO12, a new mineral species of the braunite group from Långban, Sweden
Authors: Hålenius Ulf , Bosi Ferdinando 
Published: August 2015

AbstractGatedalite, Zr(Mn22+Mn43+)SiO12, is a new mineral of the braunite group. It is found in hausmannite-impregnated skarn together with jacobsite, Mn-bearing calcite, tephroite, Mn-bearing phlogopite, långbanite, pinakiolite and oxyplumboroméite at the Långban Mn-Fe oxide deposit, Värmland, central Sweden. The mineral occurs as very rare, small (≤60 μm), grey, submetallic, irregularly rounded anhedral grains. Gatedalite has a calculated density of 4.783 g/cm3. It is opaque and weakly anisotropic with reflectivity in air varying between 17.1 and 20.8% in the visible spectral range. Gatedalite is tetragonal, space groupI41/acd, with the unit-cell parametersa= 9.4668(6) Å,c= 18.8701(14) Å,V= 1691.1(2) Å3andZ= 8. The crystal structure was refined to anR1 index of 5.09% using 1339 unique reflections collected with MoKαX-ray radiation. The five strongest powder X-ray diffraction lines [din Å, (I), (hkl)] are: 2.730(100)(224), 2.367(12)(040), 1.6735(12)(440), 1.6707(29)(048) and 1.4267(16)(264). Electron microprobe analyses in combination with single-crystal structure refinement resulted in the empirical formula: (Zr0.494+Mn0.402+Mg0.07Ca0.02Zn0.01Ce0.013+)Σ1.00(Mn4.443+Fe0.593+Mn0.572+Mg0.41Al0.01)Σ6.02Si0.99O12. Gatedalite is a member of the braunite group (general formula AB6SiO12). It is related to braunite (Mn2+Mn63+SiO12) through the net cation exchange (Zr4++ Mn2+) → 2Mn3+, which results from the substitutions Zr4+→ Mn2+at the 8-fold coordinated site (Ain the general formula) coupled with a 2Mn2+→ 2Mn3+substitution at the 6-fold coordinated sites (Bin the general formula).
Manganese incorporation in synthetic hercynite

Published: August 2015

AbstractManganese incorporation in synthetic hercynite, and partitioning between hercynite and silicate melt synthesized at 1.0 GPa, 1250°C, and at an fO2 buffered by Fe–FeO, has been studied by X-ray absorption spectroscopy and single-crystal X-ray structure refinement. Spectra indicate the presence of both Mn2+ and Mn3+ (and possibly also Mn4+) in synthetic hercynite and partitioning of Mn2+ into the melt phase, and Mn3+ into hercynite, respectively, under run conditions. X-ray refinement is consistent with partial disorder of Fe and Al across tetrahedral and octahedral sites. A higher than expected degree of Fe-Al disorder in the Mn-bearing hercynite can be explained by preferential incorporation of Mn2+ onto the tetrahedral site, and indicates that Fe-Al disorder in pure, stoichiometric hercynite cannot necessarily be used to determine closure temperatures in natural spinel. However, partitioning of Mn2+ and Mn3+ between melt and hercynite suggests that Mn incorporation in hercynite could be used as a measure of fO2 conditions in magmas during spinel crystallization.

AbstractThe new pyroxenoid barrydawsonite-(Y) occurs at the Merlot Claim, North Red Wine Pluton, Labrador, Canada (62°32'38.54'' W; 54°08'1.37'' N). The host rock is a metamorphosed eudialyte syenite consisting of eudialyte, potassic arfvedsonite, jadeitic aegirine, nepheline, albite and potassium feldspar with accessory Y-bearing pectolite, britholite and steenstrupine. Barrydawsonite-(Y) crystals commonly have discrete thin rims of Y-bearing pectolite. The average empirical formula (based on nine anions p.f.u.) is Na1.54Ca0.74Mn0.15Fe0.07Y0.38Nd0.01Sm0.01Gd0.02Tb0.01Dy0.04Ho0.01Er0.02Yb0.01Si3.00O9H. The simplified formula is Na1.5Y0.5CaSi3O9H. Barrydawsonite-(Y) is related to pectolite by the substitution ½[NaM3+Ca–2] (M3+= Y,REE), and is exceptional in being the only member of the pectolite group that has the structure of the monoclinicM2abcpolytype. The crystal structure has been determined in monoclinic space groupP21/a: a= 15.5026(2),b= 7.0233(1),c= 6.9769(1) Å, β = 95.149(1)°,V= 756.58(2) Å3(Z= 4). Final agreement indices areR1= 0.038,wR2= 0.068, Goof = 1.136. The asymmetric unit of barrydawsonite-(Y) has three metal sites:M(1) = Ca,M(2) = Na0.5(Y,REE)0.5,M(3) = Na.M(1) andM(2) are octahedrally-coordinated sites, whereasM(3) is [8]-coordinated as in pectolite and serandite. The structural formula for the empirical composition isM(3)Na1.00M(2)(Na0.50Y0.38REE0.13)Σ=1.01M(1)(Na0.04Ca0.74Mn0.152+Fe0.072+)Σ=1.00Si3O9H. There is excellent agreement between the refined site-scattering values and those calculated based upon the structural formula.Barrydawsonite-(Y) is biaxial (+) with α = 1.612(1), β = 1.617(1), γ = 1.630(1) (white light) and 2V = 63(1)°.

Low-crystallinity products of trace-metal precipitation in neutralized pit-lake waters without ferric and aluminous adsorbent: Geochemical modelling and mineralogical analysis
Authors: Sánchez-España Javier , Yusta Iñaki 
Published: August 2015

AbstractThe removal of dissolved trace metals during neutralization of acid mine drainage has usually been described and modelled as a progressive, pH-dependent sorption onto standard ferric or aluminous adsorbent. In the absence of adsorbent mineral surfaces, trace metals tend to form amorphous to low-crystallinity compounds which are often difficult to characterize. Here, we study the behaviour of the more soluble metals (Cu2+, Zn2+, Mn2+, Co2+, Ni2+, Cd2+) in the absence of ferric and aluminous adsorbent by neutralization experiments with waters from two acidic pit lakes. The objectives of our study were to identify the mineral products formed by trace-metal precipitation and the pH ranges at which these metals are removed from the solutions. Both geochemical modelling and detailed mineralogical and chemical analyses (XRD, SEM, TEM, XRF, ICP-AES) were undertaken to characterize the products. The schwertmannite and hydrobasaluminite colloids formed in the initial neutralization stages were removed from the waters at pH 3.5 and 5.1, respectively. These two minerals had previously adsorbed the Cr3+and Pb2+initially present in the solutions. The Cu precipitates were amorphous to X-rays, though chemical and modelling data suggest that Cu probably precipitated as a precursor of brochantite (Cu4(SO4)(OH)6·2H2O) at pH >6.0, together with minor quantities of other Cu hydroxysulfates (langite, antlerite) and Cu(OH)2. At higher pH, other divalent metals (Zn2+, Mn2+) precipitated as silicates, carbonates and/or (possibly) minor oxides and (oxy)hydroxides. The high concentration of aqueous SiO2in the solutions allowed Zn to precipitate as willemite (Zn2SiO4) at pH >7.0. Similarly, the presence of inorganic carbon (originally as CO2(aq.)) greatly influenced the nature of the corresponding precipitate of Mn. This metal was initially present as Mn2+and experienced a partly oxidative precipitation forming, in combination with Mg2+, the hydroxyl carbonate desautelsite (Mg6Mn2(CO3)(OH)16·4H2O) at pH 9.0–10.0. The formation of Mn3+/Mn4+oxides and hydroxides (hausmannite, manganite, birnessite) could not be demonstrated, although geochemical calculations support their subordinate formation. Other metallic cations such as Co2+, Ni2+and Cd2+did not form discrete mineral phases but were totally removed by sorption onto and/or incorporation into the cited Zn and Mn compounds. The discrepancies between theoretical and demonstrated mineralogy and the significance of these minerals for future pit-lake remediation initiatives are discussed.
Rare sulfides enriched in K, Tl and Pb from the Noril'sk and Salmagorsky complexes, Russia: new data and implications
Authors: Barkov Andrei Y. , Martin Robert F. , Cabri Louis J. 
Published: August 2015

AbstractNew results (compositional data and reflectance values) are reported for some rare sulfides enriched in K, Tl and Pb, which are related to djerfisherite, thalfenisite, bartonite, a “Cl-bearing bartonite”, or chlorbartonite, and also for shadlunite, from the Noril'sk and Salmagorsky complexes, Russia. Our observations and comparisons with relevant data in the literature imply that: (1) bartonite is probably a S-dominant (or Cl-free) analogue of djerfisherite; and a “Cl-bearing bartonite” and chlorbartonite are probably compositional variants of the djerfisherite–bartonite series. (2) The most probable formulae of bartonite and djerfisherite are (K,Me2+)6(Fe,Cu,Ni)25–xS26(S,Cl) and (K,Me2+)6(Fe,Cu,Ni)25–xS26(Cl,S), where 0 ≤ x ≤ 5, respectively. (3) Two independent substitution mechanisms probably operate in the natural series. A coupled substitution [Me2+ + S2– ↔ K+ + Cl–] is reflected by an observed deficit in K, accompanied by the incorporation of Me2+(Pb, Fe, or Ni) in the K site. Another mechanism is inferred to be [2Fe3+ + 〈 ↔ 3Fe2+], which assumes the existence of vacancy-type defects at the Me site. Thus, the second mechanism could possibly control the existing variations of Σ(Fe, Cu, Ni) in the range of ∼21 to 25 a.p.f.u., documented in djerfisherite- and bartonite-type minerals. The minerals analysed from Noril'sk, which are free of Cl and related to bartonite and to a Tl-dominant analogue of bartonite (unnamed species), probably crystallized from microvolumes of late fluid rich in K and Tl, under conditions of relatively low oxygen fugacity in the environment. Uniform contentss of Fe and Cu, observed in coexisting phases of normal (Cl-bearing) djerfisherite and bartonite (or Cl-free analogue of djerfisherite) at Salmagorsky imply that they reached equilibrium with regard to the distribution of these elements during crystallization. These phases probably formed as a result of fluctuations in the ratios of sulfur and chlorine fugacity in a fluid at a postmagmatic hydrothermal stage.
Palinspastic restoration of an exhumed deepwater system: A workflow to improve paleogeographic reconstructions

Published: August 2015

The Permian Laingsburg depocenter, Karoo Basin, South Africa, is the focus of sedimentological and stratigraphic research as an exhumed analog for offshore hydrocarbon reservoirs in deepwater basins. Thin-skinned thrust tectonics during the Permo-Triassic Cape Orogeny result in postdepositional deformation of the Permian basin fill. Regional-scale cross sections reveal two structural domains: a southern domain in the Laingsburg depocenter comprising 8–11-km wavelength north-verging fault-propagation folding, driven by buried low-angle ([Formula: see text]) reverse faults that coalesce at depth as part of a megadetachment below the Lower Paleozoic Cape Supergroup; and a northern domain to the north of the Laingsburg depocenter of short-wavelength, low-amplitude, asymmetrical folding facilitated by a detachment within the Permian Ecca Group. Five detailed structural cross sections permit the palinspastic restoration, and a calculation of the amount of shortening, across a [Formula: see text] area in the Laingsburg depocenter. Average shortening across the study area is −16.9% (5.8 km), and it decreases south to north. Shortening estimates from the Upper Ecca Group increase from 4.3 km near Matjiesfontein in the west to 10.4 km near Prince Albert in the east. Three-dimensional restorations of stratigraphic surfaces are consistent with these figures (−17%), and they allow paleogeographic and isopach thickness maps to be resorted to their configuration at the time of deposition. Structural restoration can be routinely used in outcrop studies to improve the accuracy of dimensions (e.g., volumetrics) and reconstructions (e.g., sediment dispersal patterns) derived from ancient sedimentary systems. The workflow presented here will add value to exhumed basin analogs by presenting prekinematic configurations at the frontal margins of fold-thrust belts.

Abstract

Objectives
The study was to investigate the prevention effects and possible mechanism of Yu Ping Feng San fractioned polysaccharide (YPF-P) on CCl4-induced liver fibrosis in rats.

Methods
YPF-P was prepared from root of Astragalus membranaceus, rhizome of Atractylodes macrocephaia and root of Raidix saposhnikoviae, and compared with polysaccharide from root of Astragalus membranaceus (AP). Hepatic fibrosis was induced by subcutaneous injection with carbon tetrachloride twice weekly for 12 weeks in Sprague–Dawley rats. YPF-P, AP and colchicine were administered intragastrically daily to carbon tetrachloride-treated rats. Histopathological changes of the liver and hepatic stellate cells were evaluated by Masson staining and transmission electron microscopy, respectively. Markers of fibrosis were determined by radioimmunoassay, biochemistry assay and ELISA. The mRNA expressions of tissue inhibitor of metalloproteinase-1 (TIMP-1), matrix metalloproteinase-13 (MMP-13), procollagen I and collagen III were detected by RT-PCR.

Key findings
YPF-P dose-dependently alleviated the degree of liver fibrosis and inhibited hepatic stellate cell transformation into myofibroblast-like cells, markedly reduced the elevated levels of hyaluronic acid, laminin, type IV collagen, type III procollagen, hydroxyproline and transforming growth factor beta-1, suppressed procollagen I, collagen III and TIMP-1 expression, and improved the TIMP-1/MMP-13 ratio. MMP-13 expression was only promoted moderately by YPF-P. Compared with AP, YPF-P showed more potency on most markers except laminin, type IV collagen and MMP-13 mRNA.

Conclusions
YPF-P prevented the progress of rat liver fibrosis induced by carbon tetrachloride and had a more potent preventative effect. The preventative effect may be associated with the ability of YPF-P to inhibit the synthesis of matrix collagen and balance the TIMP/MMP system.
