PLUMBISM REINVENTED

When Hymenopteran Males Reinvented Diploidy

In most plants and animals, a consistent relationship exists between the DNA content of a cell and its metabolic activity. The male-haploid sex determination of Hymenoptera and other arthropods may therefore impose a particular selective pressure upon males, which must evolve adaptations to cope with a genomic DNA reduced by half compared with that of females. Here, we show that a nuclear DNA c...

Myocardial infarction: redefined or reinvented?

The recent joint statement by the European Society of Cardiology (ESC) and the American College of Cardiology (ACC) proposing a “redefinition” of myocardial infarction has aroused much interest but also sparked considerable controversy. The basis of the new definition is the promotion of troponins to a pivotal role in the diagnosis of acute myocardial infarction, coupled with the relegation of ...

Vitamin D reinvented: implications for clinical chemistry.

THE EVIDENCE FOR NEWLY DISCOVERED ROLES FOR VITAMIN D An important clue to roles of vitamin D beyond calcium homeostasis came with the finding that the 1,25dihydroxyvitamin D nuclear receptor is present in most tissues. A reevaluation of the physiological and pharmacological actions of vitamin D produced evidence that vitamin D can regulate the immune system and thereby is implicated in several...

Apprenticeship reinvented: Cognition, discourse and implications for academic literacy

Among educational theorists and applied linguists sharing a common concern with the learning and teaching of literacy, there exist divergent understandings of the term ‘apprenticeship’. The more widespread and influential understanding is more precisely classified as ‘cognitive apprenticeship’, denoting a theory of learning that originated in North America in the late 1980s and which emphasises...
