BACKGROUND Patients with chronic ankle instability (CAI) can present with abnormal gait. The purpose of this study was to evaluate plantar pressure distributions and posture balance during walking in unilateral CAI patients. MATERIAL AND METHODS We recruited 24 unilateral CAI patients and 24 healthy individuals; plantar pressure analysis was conducted using the Footscan® 3D pressure system.

It is found that alloying addition as well as anharmonic lattice vibration and disordered atomic occupation contributes to enhance the stability of cubic structure and accordingly introduce the disordered β phase into the high-temperature microstructure. The formation of low-temperature β phase originates from not only the stabilization of cubic structure but also the destabilization of tetragonal structure.

Using an in vitro spinal cord injury model induced by glutamate treatment, we sought to investigate the neuroprotective effects of allicin in primary cultured spinal cord neurons. We found that allicin treatment significantly attenuated glutamate-induced lactate dehydrogenase (LDH) release, loss of cell viability and apoptotic neuronal death.

Flame atomic emission spectrometry (FAES) is frequently used to analyze various alkaline elements. The effects of concentrated oxy-organics in water solution on the radiation intensity of alkaline elements FAES were studied. The species and concentration of oxy-organics may affect the radiation intensity variation amplitude of alkaline elements and also the tendency of the mutation can be different dramatically.

Aim: To probe into the operation mechanism of stress, through the studies on the effects of bile secretion in rats at the condition of water immersion restraint.
Methods: The animals were divided into six groups (n=8): Group A: restraint alone under room temperature + saline; Group B: water immersion restraint + saline; Group C: restraint alone under room temperature + Atropine; Group D: water immersion restraint + Atropine; Group E: restraint alone under room temperature + Phentolamine; F group: water immersion restraint + Phentolamine.
Results: Compared with group A, the capacity of bile secretion in group B decreased significantly (P < 0.
