MiR‐513a promotes human erythroid differentiation by modulating c‐Jun
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.

Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Whole bone mechanics and mechanical testing
The Veterinary Journal, 2008The mechanical behaviour of material bone can be completely described by a group of material properties. The mechanical behaviour of the entire bone organ, however, is much more difficult to predict; it is the result both of the properties of the material of which it is made, and of the geometric spatial architecture in which this is arranged.

Mechanical Testing of Instrumentation
Spine, 1998Spinal instrumentation has a primarily mechanical function, but mechanical testing procedures are designed more by expediency than by their ability to evaluate whether instrumentation will produce a good clinical outcome. Differing testing protocols preclude direct comparisons between measurements made in different laboratories.

Precision Tests of Quantum Mechanics
Physical Review Letters, 1989It is proposed to set stringent limits on possible nonlinear corrections to ordinary quantum mechanics by searching for the detuning of resonant transitions. A suggested nonlinear generalization of quantum mechanics is used to show that such detuning would be expected in the rf transition in $^{9}\mathrm{Be}^{+}$ ions that is used to set frequency ...

Mechanical testing of urinary calculi
World Journal of Urology, 1993The ability to predict how easily a stone will break in response to extracorporeal and intracorporeal lithotripsy would be advantageous for the urologist. In a study of fragments from 52 urinary calculi, in vitro microhardness results were found to increase for the series struvite to brushite.
