From a human placental lambda gt11 cDNA library, we have isolated a cDNA clone that encodes the entire 215-residue amino acid sequence of HMG-1. Analysis of an internal sequence similarity suggests that the DNA-binding domains of HMG-1 are separated by a rather long and flexible linker segment. Southern blotting of DNA digested with BamHI indicated a highly variable number of genes (or pseudoge...

Cadmium is a toxic metal and the mechanism of its toxicity has been studied in various model systems from bacteria to mammals. We employed Saccharomyces cerevisiae as a model system to study cadmium toxicity at the molecular level because it has been used to identify the molecular mechanisms of toxicity found in higher organisms. cDNA microarray and Northern blot analyses revealed that cadmium ...

Placental development requires extensive angiogenesis and the invasion of the maternal decidua by the trophoblasts. Adequate and organized interaction of vascular endothelial growth factors (VEGF), placenta growth factors (PlGF), and their receptors are essential for a normal development and function of the placenta. In this study, we evaluated the expressions of PlGFs and their receptors, mRNA...

Histological Analysis and Immunohistochemistry Renal sections (3 μm thick) were stained with periodic acid-Schiff (PAS) and examined under light microscopy. Glomerulosclerosis index was semiquantitatively graded as 0 to 4+; vascular injury score as 0 to 3+; and tubulointerstitial injury score as 0 to 5+, according to the criteria reported previously. Ultrastructure of glomerular podocytes was a...

High-density arrays of DNA bound to solid substrates offer a powerful approach to identifying changes in gene expression in response to toxicants. While DNA arrays have been used to explore qualitative changes in gene regulation, less attention has focused on the quantitative aspects of this technology. Arrays containing expressed sequence tags for xenobiotic metabolizing enzymes, proteins asso...

Introduction:Liver has important roles in body metabolic regulation and for this reason hepatocytes are used worldwide.Investigations showed that isolation of hepatocytes causes activation of stress related genes.The aim of this study was to study the stress related expression of BEST-5 following hepatocytes isolation and culture. Method:The BEST-5 gene is cloned and analyzed for the first tim...

AIM This study investigated the association between early-life risk factors and school education outcomes. METHODS This is an historical cohort study of 7601 children (61% were Indigenous) born in the Northern Territory between 1999 and 2004. Information was linked, for each child on: perinatal health, student enrolment and National Assessment Program - Literacy and Numeracy (NAPLAN) Year 3 r...

The cap1 genes are required for the synthesis of type 1 capsular polysaccharide (CP1) in Staphylococcus aureus. We previously showed that the cap1 locus was associated with a discrete genetic element in S. aureus M. In this report, we defined the boundaries of the cap1 element by comparing its restriction pattern to that of a corresponding region from the CP1-negative strain Becker. The element...

BACKGROUND Melioidosis is less common in children than adults. The clinical spectrum of disease varies greatly between the 2 groups. Treatment guidelines are currently based on adult studies, and revision of existing guidelines is necessary to instruct specific pediatric management. METHODS Culture-confirmed cases of melioidosis in the Northern Territory between 1989 and 2013 were identified ...

TO THE EDITOR: Patients with BRAF-mutated metastatic melanoma benefit greatly from the novel BRAF inhibitor dabrafenib and the checkpoint inhibitor ipilimumab, recently listed under the Australian Pharmaceutical Benefits Scheme (PBS). Dabrafenib results in rapid responses; but the cancer later adapts, and patients relapse rapidly. Conversely, ipilimumab slowly reactivates anticancer immunity, m...
