Postsurgical status of articular cartilage after arthroscopic posterior cruciate ligament reconstruction in patients with or without concomitant meniscal pathology.

Purpose: Several factors present at the time of posterior cruciate ligament reconstruction (PCLR) may cause the subsequent progression of articular cartilage lesions. This study aimed to evaluate postsurgical articular cartilage lesions which can be seen on MRI in patients who underwent arthroscopic PCLR with or without concomitant meniscal pathology.

Material And Methods: A total of sixty-five patients (mean age 35.

Radiation dose reduction in plain radiography of the full-length lower extremity and full spine.

Objective: To compare the diagnostic performance of standard- and low-dose radiographs of the full-length lower extremity and spine.

Methods: This study included 223 patients who visited our hospital and received full-length lower extremity standing radiographs and full-spine radiographs. We determined the dose area product (DAP) of each image, and effective doses (ED, mSv) were calculated based on the DAP.

Expressed Sequence Tags Analysis and Design of Simple Sequence Repeats Markers from a Full-Length cDNA Library in Perilla frutescens (L.).

Perilla frutescens is valuable as a medicinal plant as well as a natural medicine and functional food. However, comparative genomics analyses of P. frutescens are limited due to a lack of gene annotations and characterization.
