Simple snoring: Not quite so simple after all?

Simple snoring: not quite so simple after all?

Simple snoring (SS), in the absence of obstructive sleep apnoea (OSA), is a common problem, yet our understanding of its causes and consequences is incomplete. Our understanding is blurred by the lack of consistency in the definition of snoring, methods of assessment, and degree of concomitant complaints. Further, it remains contentious whether SS is independently associated with daytime sleepi...

Not so simple after all

Biologists have long thought that the internal workings of prokary­ otes—the smallest and simplest organisms, including bacteria—are well understood, and have accordingly consid­ ered eukaryotic organisms and their cells to be more fascinating objects for study. During the past decade, however, the focus of some research has begun to turn back to prokaryotes—particularly because genomic analyse...

Regenerating the liver: not so simple after all?

Under normal homeostatic conditions, hepatocyte renewal is a slow process and complete turnover likely takes at least a year. Studies of hepatocyte regeneration after a two-thirds partial hepatectomy (2/3 PH) have strongly suggested that periportal hepatocytes are the driving force behind regenerative re-population, but recent murine studies have brought greater complexity to the issue. Althoug...
