A Multicenter Large-Sample Shear Wave Ultrasound Elastographic Study of the Achilles Tendon in Chinese Adults.

Objectives: The changes in the viscoelasticity of the Achilles tendon are related to tendinopathy. Therefore, constructing a data model in the healthy population is essential to understanding the key factors affecting the viscoelasticity of the Achilles tendon. The purpose of our research was to obtain large sample data, construct a data model, and determine parameters that affect the elastic modulus of the Achilles tendon in healthy Chinese adults.

Effect of L-arginine on the expression of Bcl-2 and Bax in the placenta of fetal growth restriction.

Objective: To investigate the effect of l-arginine on fetal growth restriction (FGR) in terms of the expression of Bcl-2 and Bax in placenta.

Methods: Sixty pregnant women with FGR were randomized to receive conventional treatment alone (control group, n = 30) or in combination with L-arginine (L-arginine group, n = 30). The parameters of fetal growth and development were monitored by B-ultrasound at regular intervals.

[Impact of catalytic ozonation with ferric hydroxide on HAAs formation potential of a filtered surface water].

Formation potential of five haloacetic acids (HAA5FP) of a filtered surface water was studied after ozonation alone and catalytic ozonation with a ferric hydroxide (FeOOH). Factors studied were oxidation time, bromide, pH, bicarbonate alkalinity, and ozone dosages. The haloacetic acids detected were dichloroacetic acid (DCAA), trichloroacetic acid (TCAA), and dibromoacetic acid (DBAA) when bromide existed.
