The respiratory effector molecules carbon monoxide (CO), nitrous oxide (N 20), and deuterium oxide (D20) were used to probe cytochrome c oxidase (EC 1.9.3.1) activity in mitochondrial particles and enzyme isolated from germinating bean seeds. Mitochondrial CO effects were dose-dependent and readily reversible, with maximal activity inhibition of 58% and 81% for mitochondria and oxidase, respect...

In this paper we prove that every nonzero ∆2 e-degree is cuppable to 0e by a 1-generic ∆ 0 2 e-degree (so low and nontotal) and that every nonzero ω-c.e. e-degree is cuppable to 0e by an incomplete

The goal of this study was to systematically investigate the ontogeny of lymphoid populations throughout postnatal development. In CD-1 mice, peak lymphocyte numbers occurred in blood on postnatal day 10 (d10) including those for natural killers (NK1.1), B cells (CD19), T helper (CD3CD4), naïve T helper (CD4CD62LposCD44low), memory T helper (CD4CD62LnegCD44high), and T cytotoxic (CD3CD8) cells....

Adsorption of DzO on the MgO(100)/Mo(100) surface has been studied using temperature programmed desorption (TPD), reflection absorption infrared spectroscopy (RAIRS) and low energy electron diffraction (LEED). The epitaxially grown MgO(100) films show virtually identical water TPD spectra as the single crystal MgO(100) surface. The first, chemisorbed layer is adsorbed with the plane of the mole...

The quadrupole splittings in the deuterium NMR spectrum from single crystals of deuterated sodium Perchlorate monohydrate, NaC104-D20, have been measured at 25 °C and — 55 °C. At room temperature, the 180° flip frequency of the D20 molecules is large compared to the difference between the splittings for the two deuterons. The average quadrupole coupling constant (e2 q Q/h) and asymmetry paramet...

A new therapeutic strategy for treating metastasis in hepatocellular carcinoma (HCC) has entailed the use of antiangiogenic agents such as suramin, BB-94 (Batimastat), TNP-470, and carboxyamido-triazole (CAI, a synthetic inhibitor of non-excitable calcium channels that reversibly inhibits angiogenesis). These agents have been used to treat metastatic model of HCC in nude mouse (LCI-D20 mouse mo...

A highly metastatic LCI-D20 model of human hepatocellular carcinoma (HCC) was obtained via orthotopic implantation of a histologically preserved metastatic tumour selected from 1 of 30 surgical specimens, and had been maintained for 18 passages in nude mice. All mice with transplanted tumours exhibited 100% transplantability and metastatic ability, as well as various manifestations reminiscent ...

Femtosecond photoionization studies in neat protio and deuterio water at room temperature have been performed. The rate of appearance of the solvated electron is slower in D,O than in H,O, consistent with the predictions of continuum theories. The observed geminate recombination dynamics of the cation-electron pair is also isotope dependent. The recombination time is slower in D20 and the fract...

Abstract The aim of this study was to evaluate the effect formulations vitamin K, organic acids, essential oils and plant hydroalcoholic extracts as anticoccidial alternatives in broilers. A 34-day cage trial with 10 replicates 12 birds/cage conducted. Male broilers (Ross 308) were randomly assigned to: 1) non-infected (NI); 2) Eimeria-infected (EI); 3) EI+decoquinate/zoalene shuttle program (D...
