OBJECTIVE To determine the adult reference intervals for the Siemens IgG subclass reagents. METHODS 636 blood samples of healthy adults were analyzed to determine the level of IgG subclass using the reagents of Siemens immunonephelometric assay with molecular biology kits. RESULTS IgGSc reference intervals were as follows: IgG1 4.45-9.76 g/L, IgG2 2.07-8.57 g/L, IgG3 0.08-0.80 g/L and IgG4 ...

Experiments were conducted to determine the tryptophan (Trp) requirement of 10- to 20-kg pigs. A Trp-deficient experimental diet (.11% total Trp, 18% CP, 3,320 kcal of ME/kg) was composed of corn, feather meal, corn gluten meal, soybean meal, and dried whey. True digestibility of Trp in the experimental diet was 70% (.077% digestible Trp) as established in a digestibility assay that involved ce...

THEORY Social homecare is important for older people, as it enables them to remain in their own homes during worsening health, thus relieving the burden on institutional facilities such as homes for the elderly or nursing homes and hospitals. METHOD A representative survey of social homecare users was employed to assess determinants of the scope of social homecare in Slovenia. Multiple regres...

Interval graphs are intersection graphs of closed intervals of the real-line. The wellknown computational problem, called recognition, asks for an input graph G whether it can be represented by closed intervals, i.e., whether G is an interval graph. There are several linear-time algorithms known for recognizing interval graphs. In this paper, we study a generalization of recognition, called par...

BACKGROUND The role of diarrhoea in the aetiology of growth retardation in young children remains controversial. To evaluate this, a population-based, longitudinal study of young children aged 6-48 months was conducted in Matlab, a rural area of Bangladesh, between May 1988 and April 1989. METHODS Data obtained from 584 children were examined by one-year (n = 412) and 3-month (n = 1220) growt...

Let x(G) and w(G) denote the chromatic number and clique number (maximum size of a clique) of a graph G. To avoid trivial cases, we always assume that w (G);?: 2. It is well known that interval graphs are perfect, in particular x( G)= w (G) for every interval graph G. In this paper we study the closeness of x and w for two well-known non-perfect relatives of interval graphs: multiple interval g...

Stool carrier rates of Escherichia coli serogroups 4, 6, and 75 were determined on admission and discharge for 190 patients. Persons who were in the hospital 3 weeks or longer had an intestinal carrier rate of 46% compared to a rate of 28% in individuals who had no recent hospital contact. Treatment with broad spectrum antibiotics increased the susceptibility for acquisition of certain specific...

Let G=(V,E) be a graph, a subset X of V is an interval of G whenever for a, b E X and xE V X , (a,x)EE (resp. (x,a)EE) if and only if (b,x)EE (resp. (x,b)EE). For instance, 0, {x}, where x E V, and V are intervals of G, called trivial intervals. A graph G is then said to be indecomposable when all of its intervals are trivial. In the opposite case, we will say that G is decomposable. We now int...
