INTRODUCTION Rates of new HIV-1 diagnoses are increasing in Australia, with evidence of an increasing proportion of non-B HIV-1 subtypes reflecting a growing impact of migration and travel. The present study aims to define HIV-1 subtype diversity patterns and investigate possible HIV-1 transmission networks within Australia. METHODS The Australian Molecular Epidemiology Network (AMEN) HIV col...

UNLABELLED Pseudocercospora is a large cosmopolitan genus of plant pathogenic fungi that are commonly associated with leaf and fruit spots as well as blights on a wide range of plant hosts. They occur in arid as well as wet environments and in a wide range of climates including cool temperate, sub-tropical and tropical regions. Pseudocercospora is now treated as a genus in its own right, althou...

Is medical school only for the rich? T imes are getting tough in Canada for those who aspire to a post-secondary education but are not from wealthy families. Surveys done at the University of Western Ontario reveal that medical students are a privileged crew, coming from homes with family incomes in the top few percentiles. This phenomenon has intensified dramatically in the last few years, coi...

Drought stress is the major limitation of common bean (Phaseolus vulgaris L.) grown in subsistence farming systems worldwide. The objective of this study was to use single nucleotide polymorphism (SNP) markers from the BARCBean6K_3 Beadchip to identify quantitative trait loci (QTL) associated with traits related to drought tolerance in common bean. An intergene pool recombinant inbred line (RIL...

‘Medark’ rice (Oryza sativaL.) (Reg.No.CV-123, PI 636725) is a high-yielding, early maturing, semidwarf, medium-grain cultivar developed by the Arkansas Agricultural Experiment Station in cooperation with the USDA-ARS, the Louisiana State University Agricultural Center, the Mississippi Agricultural and Forestry Experiment Station, and the Texas Agricultural Experiment Station. It was released i...

Over the past year, and especially over the past few months, there have appeared intimations that the newest revolution in post-genomic biology is under way. This is taking the form of microarrays of nucleic acid molecules, or DNA chips, onto which complementary probes can be annealed. Their main application is in the generation of a very large amount of data on gene expression. The activity in...

Objectives: Intramuscular injections with hypertonic saline are frequently used as induction of experimental pain that mimics chronic muscle pain (myalgia). 5-HT, a neurotransmitter, participates in the pain mediation via the 5-HT3 receptor. Granisetron, a selective 5-HT3-receptor antagonist, has previously been reported to increase the pressure pain threshold (PPT) in healthy muscles and to re...

Many nice things can be said about theory. Theories help us organize our thoughts, generate coherent explanations, and improve our predictions. In short, theories help us achieve understanding. But theories are not ends in themselves, and members of the academic field of management should keep in mind that a blanket insistence on theory, or the requirement of an articulation of theory in everyt...

This month, as the surest route to public embarassment, I decided to write about scientific heroes. Today’s world is full of talk of mentoring. Graduate students are told to find supervisors who will intellectually nourish them, emotionally support them, and teach them networking and grantspersonship. As I tap away, I can almost hear Uncle Syd muttering that the world is going to the dogs. In h...
