Angewandte Chemie International Edition, Accepted Article.Iron is in an essential micronutrient in living systems. However, it is also potentially toxic and so the concentration of chelatable iron within cells is tightly regulated to prevent catalytic formation of harmful reactive oxygen species (ROS). Ferritins play a key role in iron homeostasis by storing excess iron as an insoluble ferric mineral within ...

Metabolomic analysis reveals the molecular mechanism related to leg abnormality in broilers
Animal Research and One Health, EarlyView.The graphical abstract shows the principal results of this study. Compared to the leg normal broilers, the serum calcium to phosphorus ratio was extremely decreased in the group with deformed leg bones. Additionally, a total of nine differential metabolites significantly associated with leg abnormalities and serum calcium and phosphorus levels were ...

Animal Research and One Health, EarlyView.Dietary selenium (Se) deficiency is recognized as a global problem, and exogenous Se supplementation can effectively enrich its levels in animal bodies. Offal tissues are equally important as meat in Se enrichment. Varying properties among Se species require information beyond total Se concentration to fully evaluate health risk/benefits.

Fractionation of human immune γ-globulin [PDF]
, 1950 Equine and bovine serum proteins have recently been fractionated by means of a physical method utilizing an electrophoretic adaptation of the principles of the Clusius column (l-4), first described and tested by Kirkwood (5) and Nielsen (6).

The Hydroxymethylation of Acetoguanamine with Formaldehyde
Nippon kagaku zassi, 1966 アセトガナミンのホルマリンによるメチロール化反応を検討し,その官能基数を求めた結果,1molあたり3.3なることがわかった。この値はベンゾガナミンおよびジアミノ-6-アルコキシ-1,3,5-トリアジンの3.5よりやや小であった。また温度20°～60℃,pH-8において反応速度定数,平衡定数を測定し,これから活性化エネルギーおよび反応熱ΔHを計算し,それぞれ20.4,-4.7kcal/molの値を得た。これらの値はメラミンにくらべてほぼ同等であった。反応速度定数はすでに得られているメラミンの値にくらべ小であった。これよリメチロール化の素反応について若干の検討を加えた。平衡定数は各温度でメラミンのそれとほぼ等しいが,高濃度溶液でのメチロール化反応において両者は異なる ...

Additively Manufactured Binder‐Free Electrodes for Supercapacitors
Batteries &Supercaps, EarlyView.The study presents an innovative manufacturing process for electrodes in supercapacitors. The masked stereolithography method is used to produce electrodes that do not require a binder or metal foil. The printed electrodes have a microporous charter. Electrochemical measurements show that the additively manufactured electrodes behave in the same way as

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The optimization of hydrothermal lactic acid (LA) production from corn stover using Ca(OH)2 as catalyst was investigated. Initial studies with a 9 g L−1 glucose solution, and different Ca(OH)2 concentrations, in the range of 0.025–0.1 M, identified 0.075 M as the optimal concentration.
