Identification and Molecular Marker Detection of Leaf Rust Resistance Genes in Wheat Lines from China: Development of an Efficient Software for Gene Postulation.

Wheat leaf rust, caused by Erikss. (), is one of the most devastating diseases in common wheat ( L.) globally.

The effects of repeated freezing and thawing on bovine sperm morphometry and function.

Refreezing the remaining genetic resources after in vitro fertilization (IVF) can conserve genetic materials. However, the precise damage inflicted by repeated freezing and thawing on bovine sperm and its underlying mechanism remain largely unexplored. Thus, this study investigates the impact of repeated freeze-thaw cycles on sperm.

The complete chloroplast genome of R. Br. () and its phylogenetic implication.

The genus () is an annual parasitic twining herb. There are about 200 species in this genus, which are widely distributed in tropical and subtropical areas. is mainly parasitic on crops bringing significant losses to the production of agriculture.

MR diffusion weighted imaging for evaluation of radiotherapeutic effects on rabbit VX2 tumor model.

Objective: To investigate the feasibility of magnetic resonance (MR) diffusion weighted imaging (DWI) for evaluation of radiotherapeutic effects on rabbit VX2 tumor model.

Methods: Sixteen New Zealand white rabbits received a subcutaneous implantation of VX2 tumor cell suspension 0.5 mL (4 x 10(7) cells/mL) in their right thighs to set up tumor model.

Levonorgestrel implants enhanced the suppression of spermatogenesis by testosterone implants: comparison between Chinese and non-Chinese men.

Context: Previous male contraceptive studies showed that progestins enhance spermatogenesis suppression by androgens in men.

Objective: We compared the efficacy of spermatogenesis suppression by the combination of levonorgestrel (LNG) with testosterone (T) implants to that by T implants alone in two different ethnic groups.

Design: This was a randomized trial performed in two centers with two treatment groups.
