The present study describes the plasma levels of soluble fibronectin (FN), C3d, the breakdown product of C3 complement and Ba, the breakdown product of properdin factor B, in 30 patients of uncomplicated acute viral hepatitis (AVH), 64 patients of fulminant hepatic failure (FHF) and 29 patients of subacute hepatic failure (SAHF) with different hepatitis viral infections. Aetiological analysis o...

Objectives: Bonding of zirconia crowns and bridges to abutments is important, not only bonding of the thin resin layer to the abutment, but also bonding to the zirconia ceramic is crucial. Both mechanical and chemical adhesion are desired. Mechanical retention of dental porcelain achieved by etching with moderately concentrated hydrofluoric acid is not possible with zirconia ceramics. The purpo...

OBJECTIVES To study changes in hepatic blood flow with age. DESIGN Functional hepatic flow (FHF) and total hepatic flow (THF) were determined by non-invasive methods in 40 normal subjects in four age groups (<45, 45-60, 61-75 and >75 years). All subjects had normal routine liver function tests and no history of liver disease. RESULTS THF was measured by pulsed echo-Doppler, as the sum of po...

We propose an alternative to the usual time–independent Born–Oppenheimer approximation that is specifically designed to describe molecules with symmetrical Hydrogen bonds. In our approach, the masses of the Hydrogen nuclei are scaled differently from those of the heavier nuclei, and we employ a specialized form for the electron energy level surface. Consequently, anharmonic effects play a role ...

Social workers are increasingly called upon to provide services to homeless families, the vast majority of which arc mother-headed. Drawing on empirical findings from the literature on homeless families and the practice literature on solution-focused and strength-based practice, this article describes and illustrates how principles and techniques of these two approaches to practice can be used ...

BACKGROUND An increasing number of lesbian women and single heterosexual women are bringing up children with no male involvement. This study follows up to adolescence a sample of children raised in fatherless families from birth or early infancy. METHODS Twenty-five lesbian mother families and 38 families headed by a single heterosexual mother were compared with 38 two-parent heterosexual fam...

Fibroblast growth factors (FGFs) mediate cell growth, differentiation, migration, and morphogenesis by binding to the extracellular domain of cell surface receptors, triggering receptor tyrosine phosphorylation and signal transduction [1-5]. FGF homologous factors (FHFs) were discovered within vertebrate DNA sequence databases by virtue of their sequence similarity to FGFs [3, 6, 7], but the me...

Over the past 20 years, single-parent families have become even more common than so-called "nuclear family" consisting of a mother, father, and children. Today we see all sorts families: headed by either mother or raising their Individuals ages experience stress, but single parents are particularly vulnerable. Single often complain that they too much to do, not enough time, money maintain thems...
