Phylogenetic analysis of Asiatic species in the tropical genus Beilschmiedia (Lauraceae).

The tropial genus Beilschmiedia, comprising over 250 species worldwide, includes approximately 40 species distributed in the northern tropical forests of Asia. However, the phylogenetic relationships among these Asiatic Beilschmiedia species remain incompletely understood. In this study, we sequenced and assembled complete chloroplast genomes from six Asiatic Beilschmiedia species, including five from China and one from Indonesia.

Genomic insights and phylogenetics of the mitochondrial genome of Cryptocarya.

The tropical genus Cryptocarya is known for its valuable timber and its constituents show potential for medicinal properties. However, the phylogenetic relationships among species in Asia remain unclear. Here, we report the first mitochondrial genome assembly for Cryptocarya kwangtungensis, consisting of 758,020 bp, including 43 protein-coding genes, 23 tRNA genes and three rRNA genes, with 234 simple sequence repeats, and 1346 dispersed repeats, 35 homologous DNA fragments between the mitogenome and the plastome.

[Total knee arthroplasty with 3D printing technique versus conventional surgery: comparison of the outcomes].

Objective: To compare the clinical outcomes of patients receiving total knee arthroplasty (TKA) using 3D printing technique and conventional surgical methods.

Methods: From October, 2015 to February, 2017, 17 patients (20 knees) underwent TKA with the assistance of individualized navigation template and 16 concurrent patients (18 knees) matched for age, gender and knee society score received conventional TKA. The operation time, blood loss, and osteotomy data of the femoral condyle and tibia plateau were recorded.
