E,Anane H,Serrar C,Es-sofi A,Lamsabhi A. M,Jarid A.Is the lewis-acid behavior of GaH3 comparable to that of BH3 and AIH3? A DFT comparison study of H3AXH3 (A=B, Al, Ga and X= N, P, As) donor-acceptor complexes.Journal of Molecular Structure. 2004...
The chemical shift perturbations of cross-peaks are calculated as [(ΔH)2 + (0.2ΔN)2]1/2, where ΔH represents the chemical shift change of the amide proton, and ΔN represents the chemical shift change of the amide nitrogen of an amino acid residue. Arbitrary thresholds value = mean ...
To verify the expression levels of miR-7 in embryonic cortices, we performed northern blot analyses and detected mature miR-7 in cortices of E12.5 and throughout development using a locked nucleic acid (LNA) probe for miR-7a, which can also detect miR-7b (Figure 1B). Next, we used ...
Indolelactic acid Our findings, furthermore, indicate variations in how proteins of the antiapoptotic and BH3-only subfamilies modulate the activation of Bax and Bak. We have further explored the proposed molecular models for Bax and Bak oligomerization, utilizing the BiFC technique. Mutants of Bax...
We engaged an atmospheric plasma torch, the source of which was an aerosolized tetrachloroauric(III) acid trihydrate (HAuCl4⋅3H2O) solution. The investigation's results underscored that a solvent of pure ethanol for the gold precursor enhanced dispersion more effectively than solutions including ...
There was a significant interaction (P < 0.005) between CSB and XOS treatments on the production of cecal acetic acid, propionic acid, butyric acid, and total short-chain fatty acids (SCFAs). Propionic acid in the CSB group was significantly elevated, 154 times higher than in the control ...
{eq}H_{3}AsO_{3} {/eq} or {eq}H_{3}AsO_{4} {/eq}Oxyacids:Nitric acid is a type of oxyacid. Oxyacids contain H atoms and a polyatomic anion with an O atom. An electronegative atom is directly bonded to the O atom. The stru...
Acid and Bases:Several theories describe the characteristics of acid and bases. These theories are Arrhenius acid and base theory, the Lewis theory, and the Bronsted acid and base concept.Answer and Explanation: Electron deficient species are lewis acid, while electron-rich species...
