Victoria Land permafrost harbours a potentially large pool of cold-affected microorganisms whose metabolic potential still remains underestimated. Three cores (BC-1, BC-2 and BC-3) drilled at different depths in Boulder Clay (Northern Victoria Land) and one sample (DY) collected from a core in the
The human health risks posed by exposure to cyanobacterial toxins such as microcystin (MC) through water and fish consumption remain poorly described. During the last two decades, coastal regions of Lake Victoria such as Nyanza Gulf (Kisumu Bay) have shown severe signs of eutrophication with blooms
Seven female and three male common wombats (Vombatus ursinus) collected from forested areas of Victoria (Australia) over a 10 mo period, 10 April 1997 to 22 February 1998 had at least 30% of their skin affected by severe hyperkeratotic sarcoptic mange. Mangy wombats were grazing during the day,
Complementary DNA clones coding for the catalytic unit of the enzyme glucose-6-phosphatase (G6Pase) were obtained from Haplochromis nubilus and Haplochromis xenognathus, two cichlid fish species from Lake Victoria. The translated sequence of these two cDNAs identifies a polypeptide consisting of 352
Hematological and serum biochemical values were determined in a wild population of the mountain brushtail possum (Trichosurus caninus) at Cambarville, central Victoria, southeastern Australia. Animals were sampled during two-week trapping periods in June, September, and December 1992, and April
Guttation, the loss of water and dissolved materials from uninjured plant organs, is a common phenomenon in higher plants. By using endoplasmic reticulum signal peptides fused to the recombinant protein sequences, we have generated transgenic tobacco (Nicotiana tabacum L. cv Wisconsin) plants that
The CLN3 gene associated with Batten disease and encoding a novel protein of a predicted 438 amino acids was cloned in 1995 by the International Batten Disease Consortium. The function of CLN3 protein remains unknown. Computer-based analysis predicted that CLN3 may contain several posttranslational
OBJECTIVE
The study aimed to assess the long-term follow-up of patients with an autologous pericardial aortic valve (APAV) replacement and to analyse in vivo histopathological changes in implanted APAVs.
METHODS
From 1996 to 1997, 15 patients (mean age, 34 years) underwent aortic valve replacement
In Tanzania, pastoralists such as the Maasai and small urban farmers are responsible for the country's milk production, and 95% of the national milk supply is sold without regulation. This study was conducted using hygiene checklists and milk sampling to investigate milk quality and safety at
BACKGROUND
Non-invasive autofluorescent reporters have revolutionized lineage labeling in an array of different organisms. In recent years green fluorescent protein (GFP) from the bioluminescent jellyfish Aequoria Victoria has gained popularity in mouse transgenic and gene targeting regimes 1. It
Influenza B/LEE/40, B/Rome/1/67, B/Hong Kong/8/73, and B/Victoria/98926/70 viruses have a similar polypeptide composition as analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis. These viruses are composed of six or seven polypeptides, depending on whether one or two
Genes-encoding marker proteins, which are easily assayable, are useful to monitor cell lineage, gene expression, or promoter activities. In gene-transfer technology such marker genes allow a direct and simple detection of successfully transduced cells. The detection of marker gene products such as
