Complete genome sequence analysis of Reticuloendotheliosis virus integrated in nonhomologous Avipoxvirus.

Integration of nucleic acid sequences of Reticuloendotheliosis virus (REV) in Avipoxvirus（APV） has become commonplace. In this study, 4 strains of suspected Fowlpox virus (FPV) and 1 strain of suspected Pigeonpox virus (PPV) collected in Taiyuan, Shanxi Province were cultured in chicken embryos, and the 4b core protein gene was amplified by PCR, and the identity and genome similarity were determined by sequence analysis. The sequences between the end of ORF201 and the beginning of ORF203 of FPV and PPV were then amplified, sequenced, and subjected to sequence comparison to determine genome similarity.

Isolation and identification of a pigeonpox virus strain and study on the integration of reticuloendotheliosis virus sequence.

In order to study the integration of reticuloendotheliosis virus (REV) in pigeonpox virus (PPV), we collected suspected pigeonpox disease material, amplified the 4b core protein gene of PPV, the gp90 gene of REV, and the integrated sequence fragments from the end of the ORF201 segment of PPV to the beginning of the LTR of REV, and sequenced these genes. The results showed that a 4b core protein fragment of 332 bp was amplified and identified as pigeonpox virus, which was named SX/TY/LTR 01/2023. Sequence analysis showed that the pigeonpox virus isolate belonged to genotype A2, which was the closest to the domestic CVL strain, with a identity of 99.

The effects of different types of periodontal ligament material models on stresses computed using finite element models.

Introduction: Finite element (FE) method has been used to calculate stress in the periodontal ligament (PDL), which is crucial in orthodontic tooth movement. The stress depends on the PDL material property, which varies significantly in previous studies. This study aimed to determine the effects of different PDL properties on stress in PDL using FE analysis.

Peak loads on teeth from a generic mouthpiece of a vibration device for accelerating tooth movement.

A systematic review of the effectiveness and safety of Chinese herbal medicine formula Gualou Xiebai Banxia (GLXBBX) decoction for the treatment of stable angina pectoris.

Background: A growing number of studies suggest that Gualou Xiebai Banxia (GLXBBX) decoction, a well-known Chinese herbal formula, has beneficial effects on eliminating angina pectoris symptoms and improving condition of stable angina pectoris (SAP) patients. However, whether this treatment is effective and safe for SAP or not, evidence supporting the effectiveness and safety of this treatment is still incomplete. Besides, there is lack of systematic review to assess the detailed situation (including risk of bias and methodology) of current related clinical studies.
