An early Prussian study on the composition of milk from 1871.

Connections between the 2 scientific fields of physiology and dairy science have existed for a very long time-since the 19th century. One possible explanation for this circumstance could have been the necessity for financial support, which might have played a significant role for many theoretical physiologists to conduct studies on dairy products. This study discusses a correspondence written by the physiologist R.

Distribution of serotonin 4(a) receptors in the juvenile rat brain and spinal cord.

In the last 20 years there have been many studies investigating the distribution of 5-HT4-receptors in the brain of different species. Most studies are methodically based on RT-PCR or in situ hybridization and have analysed the receptors at the mRNA level. Furthermore there have been some autoradiographic studies using specific 5-HT4-receptor antagonists like [(3)H]GR113808, [(3)H]BIMU-1 or [(125)I]SB207710.
