The two-phase issue in the O(n) non-linear σ-model: a Monte-Carlo study Our paper [1] has motivated a comment [2] by A. Patrascioiu and E. Seiler which we reply in this note. The remarks in [2] concern three statements that the authors select from our paper: i) " The results for O(8) support the asymptotic freedom scenario ". The authors in [2] argue that at small˜β ≡ β/8 the O(8) is expected t...
There are no translations available. The inviolable assumption that obesity is simply a thermodynamic problem of calories in/calories out is being dissembled by the science linking environmental t oxins to obesity and diabetes. Exposure to environmental toxins in the absence of increased caloric intake induces weight gain and insulin resistance. Stated simply, toxins are an invisible, unappreci...
Methylenetetrahydrofolate reductase (MTHFR) is a critical folate-metabolising enzyme which requires riboflavin as its co-factor. A common polymorphism (677C T) in the MTHFR gene results in reduced MTHFR activity in vivo which in turn leads to impaired folate metabolism and elevated homocysteine concentrations. Homozygosity for this polymorphism (TT genotype) is associated with an increased risk...
The purpose of this study was to investigate the relationship between the chemical form and localization of zinc (Zn) in plant leaves and their Zn accumulation capacity. An interspecific cross between Arabidopsis halleri sp. halleri and Arabidopsis lyrata sp. petrea segregating for Zn accumulation was used. Zinc (Zn) speciation and Zn distribution in the leaves of the parent plants and of selec...
Bu çalışmada iskorpit balığı solungaç dokusundan glutatyon redüktaz enzimi literatürde ilk kez kısmi olarak saflaştırılmış ve ağır metal iyonlarının enzim aktivitesi üzerindeki etkileri belirlenmiştir. Saflaştırma işlemi homojenat hazırlanması, amonyum sülfat çöktürmesi diyaliz üç aşamada gerçekleştirilmiştir. Çalışma sonucunda optimum pH 6.5, substrat konsantrasyonu 2 mM NADPH tampon 400 KH2PO...
