Hemoglobin (Hb) Adana [HBA2: c179G>A (or HBA1); p.Gly60Asp] is a non-deletional α-thalassemia variant found in Malaysia. An improvement in the molecular techniques in recent years has made identification of Hb Adana much easier. For this study, a total of 26 Hb Adana α-thalassemia intermedia and 10 Hb Adana trait blood samples were collected from patients. Common deletional and non-deletional α-thalassemia genotypes were determined using multiplex gap polymerase chain reaction (PCR) and multiplex ARMS PCR techniques.
Selection among broilers for performance traits is resulting in locomotion problems and bone disorders, once skeletal structure is not strong enough to support body weight in broilers with high growth rates. In this study, genetic parameters were estimated for body weight at 42 days of age (BW42), and tibia traits (length, width, and weight) in a population of broiler chickens. Quantitative trait loci (QTL) were identified for tibia traits to expand our knowledge of the genetic architecture of the broiler population.
The protozoan parasite Toxoplasma gondii has a worldwide distribution; it can cause serious diseases in humans and almost all other warm-blooded animals. Different genotypes of T. gondii result in different lesions in the same host. T. gondii rhoptry protein 8 (TgROP8) is a major factor of T. gondii acute virulence. We examined sequence variation in the TgROP8 gene among T. gondii isolates from different hosts and geographical localities. The TgROP8 gene was amplified from individual isolates and sequenced.
