background co-infection with human immunodeficiency virus (hiv) and hepatitis b virus (hbv) is common due to shared routes of transmission, as reported approximately 10% of 33 million hiv-infected patients worldwide are chronically infected with hbv. mutations of hbsag especially within the “a” determinant could alter the antigenicity of the protein, causing failure of hbsag neutralization and ...

Changes in the actin-myosin interface are thought to play an important role in microfilament-linked cellular movements. In this study, we compared the actin binding properties of the motor domain of Dictyostelium discoideum (M765) and rabbit skeletal muscle myosin subfragment-1 (S1). The Dictyostelium motor domain resembles S1(A2) (S1 carrying the A2 light chain) in its interaction with G-actin...

We have determined the nucleotide sequences of two regions within the A+T-rich region of mitochondrial DNA (mtDNA) in the siIII type of Drosophila simulans and the maI type of D. mauritiana. The sequences of the two regions in siIII and maI are almost identical. The sequences include elements corresponding to the type I and type II repeats elements and the T-stretches as reported in D. melanoga...

objective: pompe disease is a rare neuromuscular genetic disorder and is classified into two forms of early and late-onset. over the past two decades, mitochondrial abnormalities have been recognized as an important contributor to an array of neuromuscular diseases. we therefore aimed to compare mitochondrial copy number and mitochondrial displacement-loop sequence variation in infantile and ad...

PURPOSE Somatic mutations in mitochondrial DNA (mtDNA) have recently been detected in various cancers. These mutations could possibly be detected in serum because mtDNA has a higher copy number than nuclear DNA. Thus, we examined genetic alterations in the D-loop region of mtDNA in hepatocellular carcinoma (HCC) patients. EXPERIMENTAL DESIGN Fifty patients with HCC were investigated in this s...

Ataxia-Telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease that is characterized by a wide range of features including, progressive cerebellar ataxia with onset during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. Mitochondrial DNA (mtDN...

Domestic chickens have long been important to human societies for food, religion, entertainment, and decorative uses, yet the origins and phylogeography of chickens through Asia remain uncertain. In this study, the complete mitochondrial (mtDNA) D-loop sequences were analyzed for a total of 27 individuals of Cambodia (n=13), Myanmar (n=6), Bangladesh (n=3) Red junglefowls (RJFs) and Laos native...
