Efficacy of periodic centrifugation of primates during 4-week head-down tilt.
TLDR
The purpose of the investigation was development of a protocol of periodic gravity loads as a counter-measure against the hypokinetic syndrome in Macaca mulatta and data imply that following HDT and HDT+G alike reduced the amount of total bodily fluids, the intracellular component, and plasma volume.

Bion 11 mission: primate experiments.
A summary is provided of the major operations required to conduct the wide range of primate experiments on the Bion 11 mission, which flew for 14 days beginning December 24, 1996. Information isExpand
Evidence for increased cardiac compliance during exposure to simulated microgravity.
TLDR
The data provide the first direct evidence that increased cardiac compliance was associated with headward fluid shifts similar to those induced by exposure to spaceflight and that reduced orthostatic tolerance wasassociated with lower cardiac contractility. Expand

Cardiovascular results from a rhesus monkey flown aboard the Cosmos 1514 spaceflight.
TLDR
Cardiovascular system changes persisted into the second day of flight and were most clearly indicated by a decrease in relative differences between blood flow to the head and total cardiac output as measured by impedance plethysmography. Expand
[Features of changes in blood pressure and blood flow in the common carotid artery of monkeys exposed aboard the biosatellite Cosmos-1514].
TLDR
Signs of cardiovascular adaptation to the effects of microgravity were discerned on flight days 3 to 5, and a significant increase when compared to the ground-based 36-hour control study. Expand
Circulation in primates exposed to microgravity aboard the "Cosmos" biosatellites.
[Oxygenation of the frontal cerebral cortex in monkeys during a two-week space flight].
TLDR
A combination of a decreased metabolic rate in the brain segment under study with a disorder in the mechanism of regulation of local cerebral blood flow is suggested. Expand
