Crossing Methods and Cultivation Conditions for Rapid Production of Segregating Populations in Three Grain Amaranth Species.

Grain amaranths (Amaranthus spp.) have been cultivated for thousands of years in Central and South America. Their grains are of high nutritional value, but the low yield needs to be increased by selection of superior genotypes from genetically diverse breeding populations.

"Remotion" total wrist arthroplasty: preliminary results of a prospective international multicenter study of 215 cases.

Wrist stability after experimental traumatic triangular fibrocartilage complex lesions.

Purpose: The aim of this study was to evaluate changes in stability of the wrist after experimental traumatic triangular fibrocartilage complex lesions.

Methods: Sixteen cadaver wrist specimens were included: 8 were fixed in neutral rotation of the forearm, 4 in maximal supination, and 4 in maximal pronation. The specimens were tested in a multiangle and torque measuring instrument.
