Maintaining Pig Temperatures in the Summer and Winter Seasons

Utah often faces extreme temperatures in the summer and winter seasons. Due to the adverse weather, it can be difficult to raise pigs. This fact sheet discusses ways to help pigs adjust to hot and cold temperatures with facilities and management techniques

Pasture Pig Basics

With an increasing push for more sustainable agriculture practices, raising pigs on pasture has gained much attention over recent years. Although it is possible to raise pigs on pasture, and this production method may support some sustainability goals, there are some important considerations. This fact sheet provides insight and answers to aspiring pig farmers so that they can make better-informed decisions before purchasing their pigs

Polymorphism in a T-cell receptor variable gene is associated with susceptibility to a juvenile rheumatoid arthritis subset

This report demonstrates a T-cell receptor (Tcr) restriction fragment length polymorphism, defined by a Tcrb-V6.1 gene probe and Bgl II restriction enzyme, to be absolutely correlated with allelic variation in the coding sequence of a Tcrb-V6.1 gene. A pair of non-conservative amino acid substitutions distinguish the Tcrb-V6.1 allelic variants. An association of this Tcrb-V6.1 gene allelic variant with one form of juvenile rheumatoid arthritis (JRA) was established in a cohort of 126 patients. The association was observed in patients possessing the HLA-DQA1*0101 gene. Among HLA-DQA*0101 individuals, 19 of 26 patients (73.1%) carried one particular Tcrb-V6.1 gene allele as opposed to 11 of 33 controls (33%; p<0.005). Haplotypes carrying this HLA gene have previously been shown to confer increased risk for progression of arthritis in JRA. This demonstration of a disease-associated Tcrb-V gene allelic variant has not, to our knowledge, been previously reported and supports the contribution of polymorphism in the Tcr variable region genomic repertoire to human autoimmune disease.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46750/1/251_2004_Article_BF00166831.pd
