σ Bond activation through tunneling: formation of the boron hydride cations BHn(+) (n = 2, 4, 6).
Athens, United States. In Phys Chem Chem Phys, Feb 2016
After using theoretical results to remove tunneling effects from the experimental rate constants, new Arrhenius fits yield activation barriers of 4.6(3) kcal mol(-1) and 3.8(1) kcal mol(-1) for the BH6(+) and BD6(+) insertion reactions, respectively, which are in near perfect agreement with converged theoretical values (4.6 kcal mol(-1) and 3.9 kcal mol(-1)).
Alterations in gene expression in the caput epididymides of nonobstructive azoospermic men.
Québec, Canada. In Biol Reprod, 2008
Differentially regulated genes included several encoding proteins involved in spermatozoal maturation, water and ion channels, and beta-defensins: CRISP1, SPINLW1, FAM12B, and DEFB129 were upregulated, whereas CFTR, AQP5, KCNK4, KCNK17, SLC6A20, SLC13A3, DEFB126, and DEFB106A were downregulated.
