Hypocomplementemic urticarial vasculitis (HUV) is the rare immune complex vasculitis, affecting small vessels and associated with anti-C1q antibodies, presenting with urticaria and hypocomplementemia. Glomerulonephritis, arthritis, obstructive pulmonary disease, and ocular inflammation are common in HUV. HUV may present as an idiopathic disease or be a part of systemic autoimmune or autoinflamm...

Human umbilical vein (HUV) endothelial cells were grown for 15 to 21 passages at a split ratio of 1:5 (at least 27 population doublings) on a human fibronectin (HFN) matrix in Medium 199 supplemented with fetal bovine serum (FBS) and endothelial-cell growth factor (ECGF). This system also permitted the growth of HUV endothelial cells at cell densities as low as 1.25 cells/cm2. In addition to de...

Human herpes virus 6 (HHV-6) is a common human pathogen that is most often detected in hematopoietic cells. Although human cells harboring chromosomally integrated HHV-6 can be generated in vitro, the availability of such cell lines originating from in vivo tissues is limited. In this study, chromosomally integrated HHV-6B has been identified in a human vascular endothelial cell line, HUV-EC-C ...

OBJECTIVES/HYPOTHESIS Health utility value (HUV) is an index used to measure health-related quality of life for the valuation and comparison of treatments. The Euroqol 5-Dimension (EQ-5D) questionnaire is a widely used method for determining HUV, but it has not been applied for this purpose in patients with chronic rhinosinusitis (CRS) who undergo sinus surgery. STUDY DESIGN Prospective cohor...

The response of the antioxidant defense system of an intertidal macroalgae Corallina officinalis L. to different dosages of UV-B irradiation was investigated. Results showed that superoxide dimutase (SOD) and peroxidase (POX) increased and then maintained at a relatively stable level when subjected to UV-B irradiation. Catalase (CAT) activity under medium dosage of UV-B irradiation (Muv) and hi...

Biologic function and the mechanical performance of vascular grafting materials are important predictors of graft patency. As such, "functional" materials that improve biologic integration and function have become increasingly sought after. An important alternative to synthetic materials is the use of biomaterials derived from ex vivo tissues that retain significant biologic and mechanical func...

PURPOSE To compare long-term patency of Heparin-Bonded Dacron (HBD) and Human Umbilical Vein (HUV) vascular prostheses in above-knee femoro-popliteal bypass surgery. DESIGN A prospective randomized multi-centre clinical trial. PATIENTS AND METHODS Femoro-popliteal bypasses were performed in 129 patients between 1996 and 2001. After randomization 70 patients received an HUV and 59 an HBD pro...

In machine learning, a popular tool to analyze the structure of graphs is the hitting time and the commute distance (resistance distance). For two vertices u and v, the hitting time Huv is the expected time it takes a random walk to travel from u to v. The commute distance is its symmetrized version Cuv = Huv +Hvu. In our paper we study the behavior of hitting times and commute distances when t...

Aiming to learn about the chemistry of the dense PDR around the ultracom-pact (UC) H II region in Mon R2, we have observed a series of mm-wavelength transitions of C 3 H 2 and C 2 H. In addition, we have traced the distribution of other molecules, such as H 13 CO + , SiO, HCO, and HC 3 N. These data, together with the reactive ions recently detected, have been considered to determine the physic...

The use of ex vivo-derived scaffolds as vascular conduits has shown to be a clinically valid approach to repair or bypass occluded vessels. Implantation of allogeneic tissue grafts requires careful processing to lower immunogenicity and prevent bacterial infection. However, the mechanical/chemical treatments used to prepare biological scaffolds can result in significant alterations to the nativ...
