This study aimed to investigate the correlations among androgen receptor (AR) CAG repeat polymorphism, sex hormones and penile length in healthy Chinese young adult men. Two hundred and fifty-three healthy men (aged 22.8 ± 3.1 years) were enrolled. The individuals were grouped as CAG short (CAG S ) if they harbored repeat length of ≤ 20 or as CAG long (CAG L ) if their CAG repeat length was >20...
thirtyfrieswal lactating cows were screened for clinical and subclinical mastitis and subsequently classified into healthy, subclinically affected and clinically affected groups each group comprising of 10 cows. polymorphism of cow lactoferrin (ltf) gene promoter was determined by polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp). the results showed that lft gene pro...
background and objectives: avian tuberculosis is one of the most important infections affecting most species of birds. mycobacterium avium can not only infect all species of birds, but also infect some domesticated mammals.the most crucial aspect of control and eradication scheme is identification of infection sources and transmission routs. mo- lecular techniques such as restriction fragment l...
background: henoch-schönlein purpura (hsp) is an lga mediated small vessel systemic vasculitis disease in children. the etiology and pathogenesis of hsp disease remain unknown. however, environmental and genetic risk factors could play important roles in susceptibility to hsp disease. in this study we investigated the association of 5՛-untranslated region polymorphism (-634g/c) of vegf gene wit...
Bovine tuberculosis caused by Mycobacterium bovis remains a significant disease of farmed cattle in many countries despite ongoing tuberculosis eradication programs. Molecular typing methods such as restriction fragment length polymorphism (RFLP) analysis and spoligotyping have been used to identify related herd breakdowns in an attempt to identify more precisely the route of infection into cat...
Assessing microbiological quality assurance by monitoring bacteria in various sources of freshwater used for human consumption, recreation, and food preparation is important for a healthy life. Bacterial number and their community structure in freshwater should be determined as quickly as possible, and "real-time" and "on-site" microbiological methods are required. In this study, we examined th...
Among 12 clarithromycin-resistant Helicobacter pylori strains isolated in Guri, Korea, 8 showed an adenine to guanine mutation at position 2143 (formerly A2144G or E. coli 2059) in the 23S rRNA gene by the PCR-restriction fragment length polymorphism (RFLP) method. The remaining 4 strains, digested by neither BsaI nor BbsI, showed a thymine to cytosine mutation at position 2182 (T2182C) by dire...
The present study utilizes polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis using partial plastid rbcL and mitochondrial trnC-trnP gene sequences to distinguish the six representative Pyropia species produced via mariculture in Korea. The rbcL, trnC, and trnP sequences of 15 Pyropia species from the NCBI database were aligned to determine specific restricti...
