Hypotheses and facts.
The book, The river, is based on assumptions and not facts. Oral polio vaccine was produced entirely in rhesus monkey kidney cell cultures. Allegations that it was produced in chimpanzee kidneys at the Wistar Institute in Philadelphia or, alternatively, that the vaccine was made in the then Belgian Congo in chimpanzee kidney has no basis in fact. As the only witness to the historical events lea...
متن کاملVertical nystagmus: clinical facts and hypotheses.
The pathophysiology of spontaneous upbeat (UBN) and downbeat (DBN) nystagmus is reviewed in the light of several instructive clinical findings and experimental data. UBN due to pontine lesions could result from damage to the ventral tegmental tract (VTT), originating in the superior vestibular nucleus (SVN), coursing through the ventral pons and transmitting excitatory upward vestibular signals...
متن کاملSex hormones, glucocorticoids and autoimmunity: facts and hypotheses.
Increasing knowledge on the regulation of immune responses over the past decade has made it clear that the immune system is involved in complex interactions with most, if not all, of the biological systems responsible for normal homeostasis. The evidence for important interplays between the immune and endocrine systems has launched the whole new field of neuroimmunoendocrinology which has attra...

متن کاملProtein Phosphatases Involved in Regulating Mitosis: Facts and Hypotheses
Almost all eukaryotic proteins are subject to post-translational modifications during mitosis and cell cycle, and in particular, reversible phosphorylation being a key event. The recent use of high-throughput experimental analyses has revealed that more than 70% of all eukaryotic proteins are regulated by phosphorylation; however, the mechanism of dephosphorylation, counteracting phosphorylatio...
