OBJECTIVES To assess the ability of reactive hyperemia-peripheral artery tonometry (RH-PAT) to serve as a surrogate marker of endothelial dysfunction in children with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS Forty-four children with T1D [age 14.6 +/- 2.7 yr; duration of diabetes 6.01 +/- 4 yr; range of diabetes duration 1-16 yr; and hemoglobin A1c (HbA1c) 8.34 +/- 1.2%] and 20 child...

A spectroscopic investigation of complexes used to catalyze the oxidative carbonylation of toluene to p-toluic acid was conducted. Rhodium complexes were analyzed by (103)Rh and (13)C NMR, UV-visible spectroscopy, and infrared spectroscopy. In the presence of vanadium and oxygen, the resting state of the Rh-catalyst was found to exist as a Rh(III) complex with carbonyl and trifluoroacetate liga...

The Rh blood group system plays a major role in immune and nonimmune hemolytic states. Although an Rh cDNA has been previously cloned, there is no information on which Rh antigenic protein it encodes. Using polymerase chain reaction (PCR) amplification, we have identified this original Rh clone, here designated Rh21, and an additional Rh cDNA clone, Rh13, that is 96% nucleotide- and 92% amino a...

The title compound, [Rh(C(5)H(7)O(2))(C(18)H(12)Cl(3)P)(CO)], contains the bidentate acetyl-acetonate ligand coordinated to the Rh(I) atom, forming a chelate ring [Rh-O = 2.0327 (15) and 2.0613 (14) Å]. The Rh(I) atom is additionally coordinated by one P [Rh-P = 2.2281 (6) Å] and one carbonyl C [Rh-C = 1.812 (2) Å] atom, resulting in a slightly distorted square-planar geometry. The mol-ecules a...

Solutions of glycerol and water provide a convenient and inexpensive system to control the relative humidity (RH) in small controlledenvironment chambers. The relationship between the specific gravity (SG) of a glycerol-water solution and its equilibrium RH is described by the equation SG = [-0.189 (RH) + 19.9] 0.0806 . Gas can be humidified by bubbling it through jars containing solutions of g...

The reaction of [Rh(μ-Cl)(cod)]2 with diimines, differing in their steric and electronic properties, diphenylphosphine oxide leads to the oxidative addition products, hydrido-phosphinito-Rh(III) complexes {Rh(PPh2OH)(PPh2O)(NN)(H)Cl} (1), stabilized by formation a hydrogen bonded phosphinous acid-phosphinito quasi-chelate [(PO⋅⋅⋅HOP)-κ2P]. Exchange hydride chloride afford {Rh(PPh2OH)(PPh2O)(NN)...

The effect of ractopamine hydrochloride (RH) and zilpaterol hydrochloride (ZH) on slice shear force (SSF) and sensory characteristics of beef from calf-fed Holstein steers was evaluated. All steers were implanted with a progesterone (100 mg) plus estradiol benzoate (10 mg) implant followed by a terminal trenbolone acetate (200 mg) plus estradiol (40 mg) implant. Steers were blocked by weight in...

Monometallic complexes of the tetrakis(pyrazolyl)borate ligand [ML(2){B(pz)(4)}] {M = Rh, Ir; L(2) = eta-cod, eta-nbd, (CO)(2), (CO)(PPh(3))} have two free pyrazolyl rings which can be coordinated to a second ML(2) unit to give the dimeric compounds [L(2)M{mu-B(pz)(4)}ML(2)](+), and to a metal halide to give heterobimetallic species [L(2)M{mu-B(pz)(4)}M'Cl(2)]. (1)H NMR spectroscopy shows that ...

By following the titer of passively acquired Rh antibodies in newborn infants, it is calculated that the half-life of the placenta-passing Rh antibody molecule is approximately 30 days. Evidence is offered that this estimate applies not only to placenta-passing Rh antibodies, but also to other placenta-passing antibodies, and not improbably to serum gamma globulin molecules in general. Studies ...

Using local density functional calculations, we studied the morphological changes of Mo(1 1 1) and W(1 1 1) upon the adsorption of an ultrathin ®lm of Rh. The unusual relaxations induced by Rh on Mo(1 1 1) and W(1 1 1) surfaces should be caused by competing several factors such as Smoluchowski smoothing e€ect, change of atomic interactions, and charge transfer between overlayer and substrate. I...
