Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

Advanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Simulated weightlessness for the ontogenesis of the otolith organ

Die Naturwissenschaften, 1968
Abstract : The critical phase of the otolith-organ-ripening within the embryo was used in a simulation experiment by setting frog eggs (Rana temporaria) and toad eggs (Bufo bufo) near the center of a rotating system with a horizontal axis. The experiment speeds were 100 and 160 r.p.m.; the eggs and tadpoles were subjected to maximal centripetal forces ...

Exercise response to simulated weightlessness

Acta Astronautica, 1979
Two bed rest analog studies of space flight were performed; one 14 d and the other 28 d in duration. Exercise response was studied in detail during the 28 d study and following both the 14 d and 28 d studies. This paper relates the results of these studies to physiologic changes noted during and following space flight.

An upper arm model for simulated weightlessness

Acta Physiologica Scandinavica, 2000
This investigation examined the effects of 4 weeks of non‐dominant arm unloading on the functional and structural characteristics of the triceps brachii muscle of six normo‐active college‐age males (age: 23 ± 1 years, height: 176 ± 4 cm, weight: 76 ± 6 kg).

The Effects of Simulated Weightlessness on Bone Maturation*

Endocrinology, 1987
In earlier studies we showed that elevating the hind limbs of growing rats for up to 2 weeks results in a temporary cessation of bone growth in the hind limbs and a transient fall in the serum levels of 1,25-dihydroxyvitamin D. To determine whether such skeletal unloading also retards the maturation of bone, as seen in vitamin D-deprived animals, we ...
