In-vitro endothelialization of patches of bovine jugular vein stabilized by dye-mediated photooxidation.

Background And Aim Of The Study: The study aim was to evaluate the cytotoxicity of photooxidatively stabilized bovine jugular vein and the in-vitro endothelialization properties of such material.

Methods: Bovine jugular veins were cross-linked by dye-mediated photooxidation and cut into 4 cm2 pieces. Ovine jugular vein endothelial cells were isolated, cultured, and then seeded onto the inner surface of bovine jugular vein patches at a density of 1.

[Prenatal ultrasonographic evaluation of fetal limbs anatomy and fetal limbs malformations using a systematic continuous sequence approach].

Objective: To review the value of ultrasonographic evaluation on fetal limbs anatomy and malformations in prenatal diagnosis using a systematic continuous sequence approach (SCSA).

Methods: Successive 4,932 prenatal ultrasonographic evaluation during gestation aging 14 - 40 weeks from August 2000 to September 2002 entered the present review. SCSA was applied to scan each limb of the fetus respectively.

trans-Diaquabis(thiosemicarbazido-kappa2N,S)nickel(II) dimaleate dihydrate.

In the title compound, [Ni(CH(5)N(3)S)(2)(H(2)O)(2)](C(4)H(3)O(4))(2).2H(2)O, the Ni atom lies on a center of symmetry and is coordinated by N and S atoms from two thiosemicarbazide ligands and the O atoms of two water molecules in a distorted octahedral geometry. In the asymmetric unit, the three components are linked together by one O-H.

[Using purified conjugated bilirubin as a calibrator for bilirubin measurement].

Objectives: To improve the accuracy and precision of the determination of bilirubin, especially direct bilirubin (DB), and the standardization of that as well.

Methods: Purified conjugated bilirubin (Bc) and ditaurobilirubin(DTB) and their diazo products were subjected to absorption spectrum analysis. The diazo reaction characters of their calibration solutions were compared by the method of Doumas J-G(TB & DB).

Studies on the two-photon pumped upconverted fluorescence and superradiance of a new organic dye material in solutions.

The linear and nonlinear optical properties of a new organic dye, trans-4-[p-(N-ethyl-N-ethylamino)-styryl]-N-methyl-pyridinium tris(thiocyanato) cadmates (II), are reported in this paper. When pumped with a picosecond laser at the wavelength range of 850-1200 nm, intense upconversion fluorescence can be obtained. The upconversion efficiencies at different pump energies were measured when pumped with a 1064-nm laser beam from a mode-locked Nd:YAG laser.
