Clinical audits can work if they are followed up correctly

Nice work if you can get it.

Are Platelets Cells? And if Yes, are They Immune Cells?

Small fragments circulating in the blood were formally identified by the end of the nineteenth century, and it was suggested that they assisted coagulation via interactions with vessel endothelia. Wright, at the beginning of the twentieth century, identified their bone-marrow origin. For long, platelets have been considered sticky assistants of hemostasis and pollutants of blood or tissue sampl...

Quadrangulations of the projective plane are t-perfect if and only if they are bipartite

We show that every non-bipartite quadrangulation of the projective plane contains an odd wheel as a t-minor and is thus t-imperfect.

Broilers (Gallus gallus) are less stressed if they can smell a mother odorant

Performance, physiological and behavioural parameters of two groups of domestic chickens were compared. Chickens were raised in classical commercial conditions in buildings housing 12000 birds. One group acted as a control, while the environment of the other was perfused with MHUSA (Mother Hens’ Uropygial Secretion Analogue), a synthetic analogue of a mother-hen odorant secretion which has show...

Regeneration If They Can Do It, Why Can't We?

The therapeutic potential of stem cells and nuclear cloning has led to renewed interest in classical models of regeneration. This longstanding problem is undergoing a renaissance spurred by the availability of new techniques that finally allow analysis on the cellular and molecular level.
