Published: November 2019

Złożoność etiopatogenezy schorzeń autoimmunologicznych, w tym celiakii i choroby Hashimoto oraz brak skutecznej farmakoterapii powoduje, że istotnym czynnikiem poprawy stanu zdrowia i komfortu życia oraz zmniejszenia rozwoju powikłań może być odpowiednia dietoterapia. W badaniach własnych zaobserwowano, że jedna trzecia osób z celiakią oprócz wyłączenia zbóż glutenowych eliminowała z diety produkty mleczne. Większość osób z chorobą Hashimoto wyłączyła z diety zboża glutenowe, a ponad połowa również produkty mleczne i soję. Największą poprawę stanu zdrowia, w tym szczególnie zmniejszenie występowania nudności, wzdęć, dolegliwości bólowych oraz zwiększenie uczucia komfortu obserwowały osoby z celiakią eliminujące oprócz zbóż glutenowych: mleko i jego przetwory, orzechy i soję. Podobnie największe zmiany samopoczucia związanego z objawami choroby Hashimoto, w tym szczególnie zmniejszenie nadwrażliwości na temperaturę, uczucia suchości skóry oraz poprawę samopoczucia deklarowały osoby eliminujące zboża glutenowe, produkty mleczne, orzechy arachidowe i warzywa psiankowate. Leczenie celiakii oparte na diecie bezglutenowej połączone z eliminacją orzechów i soi może przynieść największe korzyści związane z poprawą stanu zdrowia i jakości życia, a eliminacja zbóż glutenowych i orzeszków ziemnych może wspomagać poprawę jakości życia osób z chorobą Hashimoto.

Znaczenie ryb i przetworów rybnych w żywieniu człowieka – analiza korzyści i zagrożeń
Authors: Januszko Olga , Kałuża Joanna 
Published: November 2019

Ryby i owoce morza są ważnym elementem prawidłowo zbilansowanej diety, na każdym etapie rozwoju i życia człowieka. Spożywanie ryb co najmniej 2 razy w tygodniu zalecane jest przez żywieniowców na całym świecie w celu profilaktyki choroby niedokrwiennej serca i nowotworów. Jednak ze względu na istnienie ryzyka zanieczyszczenia tych produktów m.in. metylortęcią i dioksynami, dla grup wrażliwych (kobiet w ciąży, karmiących piersią oraz dzieci) wprowadzono pewne ograniczenia odnośnie ich spożycia. Jednocześnie podkreśla się, że korzyści zdrowotne wynikające ze spożycia umiarkowanych ilości ryb przez kobiety w ciąży przewyższają ryzyko. W wielu krajach podjęto działania edukacyjne w zakresie zaleceń żywieniowych, dotyczące ograniczenia spożycia określonych gatunków ryb morskich ze względu na zawartość w nich metylortęci. Istotna wydaje się być edukacja kobiet ciężarnych, karmiących piersią oraz w wieku rozrodczym dotycząca spożycia ryb, ich wartości odżywczej oraz wyboru odpowiednich gatunków.

Published: November 2019

Field experiments were undertaken on sandy soils with three cropping systems at Giridih, Jharkhand, India for two years during 2012-2014. The experiments were executed in split plot design by assigning water soluble phosphorus (WSP) fertilizers in main-plot and recommended dose of phosphorus (RDP) in sub-plot with three replications. The maximum economical yield of rice (4705 kg/ha), baby corn (842 kg/ha) and Chickpea (920 kg/ha) were recorded with the application of 30% WSP. The maximum economical yield of successive crops - wheat (3185 kg/ha), mustard (1720 kg/ha) and groundnut (1578 kg/ha) were recorded with the application of 30% WSP and 100% RDP treatment. Almost similar trends were noticed in terms of by-product yield, nutrient uptake and residual soil fertility status. All the levels of WSP (30% - 89%) in complex fertilizers were found to be equally effective for grain yield, straw yield, nutrient uptake, and residual soil fertility.

Abstract
A new mineral, metathénardite, ideally Na2SO4, the high-temperature hexagonal dimorph of thénardite, a natural analogue of the synthetic phase Na2SO4(I), was found in the sublimates of active fumaroles at the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure eruption, Tolbachik volcano, Kamchatka, Russia. The holotype originates from the Glavnaya Tenoritovaya fumarole in which metathénardite is associated with hematite, tenorite, fluorophlogopite, sanidine, anhydrite, krasheninnikovite, vanthoffite, glauberite, johillerite, and lammerite. The cotypes 1 and 2 are from the Arsenarnaya (with hematite, tenorite, fluorophlogopite, sanidine, euchlorine, wulffite, anhydrite, fluoborite, johillerite, nickenichite, calciojohillerite, badalovite, tilasite, cassiterite, and pseudobrookite) and the Yadovitaya (with tenorite, euchlorine, fedotovite, dolerophanite, langbeinite, krasheninnikovite, anhydrite, and hematite) fumaroles, respectively. All specimens with metathénardite were collected from areas with temperatures of 350–400 °C. Metathénardite forms hexagonal tabular, lamellar, or dipyramidal crystals (forms: {001}, {100}, {102}, and {201}) up to 3 mm combined in crusts up to several hundred cm2 in area. The mineral is transparent to semitransparent, colorless, white, light-blue, greenish, yellowish, grayish or brownish, with vitreous luster. Dmeas. = 2.72(1), Dcalc. = 2.717 g/cm3. Metathénardite is optically uniaxial (–), ω = 1.489(2), ε = 1.486(2). The empirical formulae are (Na1.92K0.05Ca0.02Zn0.01)[S0.99O4] (holotype), (Na1.54K0.22Ca0.09Cu0.01Mg0.01)[S1.00O4] (cotype 1), and Na1.65K0.11Ca0.05Cu0.04Mg0.01)[S1.01O4] (cotype 2). Admixed K and bivalent cations probably stabilize the hexagonal aphthitalite-like structure of metathénardite at room temperature. The crystal structure was solved using single crystals of all three samples, R1 = 0.0852, 0.0452, and 0.0449 for holotype and cotypes 1 and 2, respectively. The space group is P63/mmc, and the unit-cell parameters of the holotype are a = 5.3467(9), c = 7.0876(16) Å, V = 157.47(6) Å3, and Z = 2. The strongest reflections of the powder X-ray diffraction pattern [d,Å(I)(hkl)] are: 4.667(27)(100), 3.904(89)(101), 3.565(33)(002), 2.824(94)(102), 2.686(100)(110), and 1.939(35)(202). Metathénardite and thénardite clearly differ from one another in X-ray diffraction data and infrared and Raman spectra.
