Mad Cows, Demented Humans and Food

Fears lessen for human BSE

Alarm bells rang eight years ago with the evidence that mad cow disease could pass from cows to humans via the food chain. But new research suggests that the disease, although still a problem in a number of countries, will have a limited effect on the human population.

Prion diseases: Transmission from mad cows?

Prion diseases in humans show considerable clinical and pathological heterogeneity. The identification of a new variant of Creutzfeldt-Jakob disease, and its interpretation as evidence of transmission of mad cow disease to man, rely critically on our understanding of the epidemiology of prion diseases.

Mad cows, mad corn and mad communities: the role of socio-cultural factors in the perceived risk of genetically-modified food.

The rapid globalization of the world economy has increased the need for a knowledge base of reliable socio-cultural differences in perceptions, values and ways of thinking about new food technologies. Awareness of socio-cultural differences is important because collaborative efforts to deal with food hazards presuppose some understanding of where, how and why the viewpoints of various stakehold...

Comparison between two progesterone sources and two oestradiol formulations in a Heatsynch protocol for postpartum cycling dairy cows in pasture

To compare an injectable progesterone (MAD-4) with an intravaginal device (IPD), and natural O17 with synthetic oestradiol (OB) in a synchronisation protocol, 51 cows were divided into four groups. Each group was treated with one of the two sources of progesterone and one of the two oestradiol formulations. Oestrus behaviour, follicle diameter, and pregnancy rates were evaluated. Oestrus behavi...
