Abstract Sustainable modern poultry production depends on effective protection against infectious diseases and a diverse range of antibodies is key for an immune response. In the domestic chicken, somatic gene conversion dominant process in which antibody immunoglobulin genes are diversified. Affinity maturation by hypermutation (SHM) also occurs, but relative contribution versus to (Ig) divers...

Two breeds of chickens were used to develop reference family and detect QTLs affecting egg quality traits: cocks of a native Polish breed Green-Legged Partidgenous (GlP) and hens of Rhode Island Red (RIR). During the first 100 days of the laying period, the GlP hens lay about 40 eggs weighting on average 50 g, whilst the RIR flock laid 83 eggs with a mean weight of 60 g. QTL analysis of egg qua...

Multicenter clinical research studies are often needed to address issues of generalizability, conditions with low incidence, adequate statistical power, and potential study bias. While pediatric research networks began work in the 1950s, and Rhode Island physicians have contributed to many of these studies, pediatric emergency medicine (PEM) collaboratives are relative newcomers. Since the mid-...

Primers were used to amplify a 561-bp region of the 16S rRNA gene of Ehrlichia phagocytophila from Ixodes scapularis ticks and small mammals collected in Rhode Island and Connecticut. DNA sequences for all 50 E. phagocytophila-positive samples collected from 1996 through 1998 in southwestern Connecticut were identical to the sequence reported for E. phagocytophila DNA from confirmed human cases...

Appreciated for their versatile nutritive value and functional properties, eggs are considered as an important item in human diet. Eggs are one of the most common foods available worldwide as they play an important role in human diet by providing humans with protein, lipids, minerals and vitamins in an adequate amount. Chicken breeds differ in physical and biochemical contents in terms of eggs ...
