Advances in biotechnology has been the subject of praise for a decade now, this is due to techniques such as gene expression which contributed immensely success genetic engineering, medical advancement, vaccine production and agriculture. Gene become very important tool overall improvement quality life. This paper tries look into development last forty years highlight how technological advancem...

We studied the serovar distribution of Chlamydia trachomatis in patients with clinical eye disease in Western Australia. Most disease occurred in indigenous communities and was caused by trachoma serovars Ba and C. Serovar Ba was genetically homogeneous throughout Western Australia and identical to strains previously described in indigenous communities in Northern Territory. This finding probab...

Human mitochondrial long noncoding RNAs (lncRNAs) have not been described to date. By analysis of deep-sequencing data we have identified three lncRNAs generated from the mitochondrial genome and confirmed their expression by Northern blotting and strand-specific qRT-PCR. We show that the abundance of these lncRNAs is comparable to their complementary mRNAs and that nuclear-encoded mitochondria...

Age-associated slowing of cardiac relaxation related to the decline in the Ca2+ pump function of cardiac sarcoplasmic reticulum (SR) has been previously described. It is unclear if the decreased Ca2+ pump function results from a lower amount of Ca2(+)-ATPase protein or a decreased pumping activity of the enzyme. To determine if these alterations could be mediated by changes in the amount of the...

miR-21 is the most commonly over-expressed microRNA (miRNA) in cancer and a proven oncogene. Hsa-miR-21 is located on chromosome 17q23.2, immediately downstream of the vacuole membrane protein-1 (VMP1) gene, also known as TMEM49. VMP1 transcripts initiate ∼ 130 kb upstream of miR-21, are spliced, and polyadenylated only a few hundred base pairs upstream of the miR-21 hairpin. On the other hand,...

The mouse MHC class I family includes genes encoded in four regions: H-2K, H-2D, Qa and Tla. While K/D genes are well characterized, relatively little is known about Qa or Tla genes. We have studied the transcription of a B10.P Qa region gene. DNA sequence comparisons of the transmembrane region, supported by Southern blot analysis of cosmid and genomic DNAs from BALB/c and C57BL/10, demonstrat...

In order to access the role of the Porphyromonas gingivalis Arg-gingipain proteases in the virulence of this organism, a mutant defective in the rgpA gene was constructed in strain 381. This mutant, MT10, displayed only 40% of the Arg-specific cysteine protease activity of the wild-type strain. In addition, MT10, as well as the recently characterized protease mutant G-102, which is defective in...

OBJECTIVES To determine the prevalence and trends of human hookworm infection (HWI) in the Northern Territory over the past 10 years, and to assess the influence of the community children's deworming program (CCDP). DESIGN, PATIENTS AND SETTING A retrospective observational analysis of consecutive microbiologically confirmed cases of HWI in patients diagnosed at NT government health care faci...
