Since 1971, 21 placebo-controlled studies have been made to establish whether vitamin C at a dosage of ≥ 1 g/day affects the common cold. These studies have not found any consistent evidence that vitamin C supplementation reduces the incidence of the common cold in the general population. Nevertheless, in each of the 21 studies, vitamin C reduced the duration of episodes and the severity of the...

Chronic exposure to food of low quality may exert conflicting selection pressures on foraging behaviour. On the one hand, more active search behaviour may allow the animal to find patches with slightly better, or more, food; on the other hand, such active foraging is energetically costly and thus may be opposed by selection for energetic efficiency. Here we test these alternative hypotheses in ...

Background: Ascorbate biosynthesis in plants occurs mainly via the L-galactose pathway. Results: Chlamydomonas reinhardtii VTC2 encodes a GDP-L-galactose phosphorylase whose transcript levels are induced in response to oxidative stress concurrent with increased ascorbate accumulation. Conclusion: Increased oxidative stress in C. reinhardtii results in an enzymatic and nonenzymatic antioxidant r...
