Towards quantitative and intuitive percutaneous tumor puncture via augmented virtual reality.

Comput Med Imaging Graph 2021 Mar 31;90:101905. Epub 2021 Mar 31.

Department of Computer Science and Engineering, Chinese University of Hong Kong, Hong Kong SAR, China.

In recent years, the radiofrequency ablation (RFA) therapy has become a widely accepted minimal invasive treatment for liver tumor patients. However, it is challenging for doctors to precisely and efficiently perform the percutaneous tumor punctures under free-breathing conditions. This is because the traditional RFA is based on the 2D CT Image information, the missing spatial and dynamic information is dependent on surgeons' experience. Read More

Characterization of mandarin fish (Siniperca chuatsi) IL-6 and IL-6 signal transducer and the association between their SNPs and resistance to ISKNV disease.

Fish Shellfish Immunol 2021 Apr 10. Epub 2021 Apr 10.

Pearl River Fisheries Research Institute, Chinese Academy of Fishery Sciences, Key Laboratory of Fishery Drug Development, Ministry of Agriculture and Rural Affairs, Key Laboratory of Aquatic Animal Immune Technology, Guangdong Provinces, Guangzhou, 510380, China.

In fish, interleukin-6 (IL-6) is a very important immune-regulatory cytokine that plays a polyfunctional role in inflammation, metabolism, regeneration, and neural processes. IL-6 signal transducer (IL-6ST) is a specific receptor for IL-6 and expressed mainly in immune cells and hepatocytes. In this study, the complete cDNA and genomic DNA sequences of mandarin fish (Siniperca chuatsi) IL-6 and IL-6ST genes were identified and analyzed. Read More

Development and Application of SYBR Green Ⅰ Real-time Quantitative Reverse Transcription PCR Assay for Detection of Swine Getah Virus.

Mol Cell Probes 2021 Apr 10:101730. Epub 2021 Apr 10.

College of Veterinary Medicine, Henan Agricultural University. Electronic address:

Getah virus (GETV), a mosquito-borne virus belonging to the Alphavirus genus of family Togaviridae, has become increasingly problematic, which poses a huge threat to the safety of animals and public health. In order to detect GETV quickly and accurately, we have developed a SYBR Green I real-time quantitative reverse transcription PCR (RT-qPCR) assay for GETV with the detection limit of 66 copies/μL, excellent correlation coefficient (R) of 0.9975, and amplification efficiency (E) of 98.

Synergistic effects of green tea extract and Paclitaxel in the induction of mitochondrial apoptosis in ovarian cancer cell lines.

Gene 2021 Apr 10:145638. Epub 2021 Apr 10.

Department of Medical Radiation, Faculty of Engineering, Islamic Azad University, Science and Research Branch, Tehran, Iran. Electronic address:

Background: Green tea is a natural compound with anti-neoplastic properties. Paclitaxel (PTX) is a natural anti-tumor medication used to manage patients with advanced ovarian cancer. This manuscript evaluated the cytotoxic effects of green tea extract combined with PTX drug in two human ovarian cancer cell lines (p53-negative cell line, SKOV-3; and mutant type p53 cell line, OVCAR-3) and underlying mechanisms.

Genome-wide characterization and expression profiling of the PDR gene family in N. tabacum.

Gene 2021 Apr 10:145637. Epub 2021 Apr 10.

China Tobacco Gene Research Center, Zhengzhou Tobacco Research Institute of CNTC, Zhengzhou, 450001, China. Electronic address:

The pleiotropic drug resistance (PDR) proteins of the ATP-binding cassette (ABC) family play essential roles in physiological processes and have been characterized in many plant species. However, no comprehensive investigation of tobacco (Nicotiana tabacum), an important economic crop and a useful model plant for scientific research, has been presented. We identified 32 PDR genes in the tobacco genome and explored their domain organization, chromosomal distribution and evolution, promoter cis-elements, and expression profiles. Read More

J Feline Med Surg 2021 Apr 13:1098612X211005301. Epub 2021 Apr 13.

Ontario Veterinary College, Guelph, Canada.

Objectives: The aim of this study was to optimize the diagnosis of feline panleukopenia virus (FPV) in a shelter setting by: (1) comparing the results of the canine parvovirus IDEXX SNAP Parvo (SNAP) point-of-care ELISA with a commercial FPV quantitative real-time PCR (qPCR) test; (2) assessing whether vomit and anal/rectal swabs could be used for early diagnosis; and (3) clarifying the interpretation of weak-positive SNAP test results.

Methods: The study included shelter cats and kittens with incomplete or unknown vaccination history that had clinical signs suspicious for feline panleukopenia and fecal SNAP and PCR tests performed within 24 h of onset. Feces, anal/rectal swabs and vomit were tested using SNAP and PCR, with fecal PCR utilized as the reference standard. Read More
