Nanosecond pulsed electric field ablates rabbit VX2 liver tumors in a non-thermal manner.

Background: Liver tumor remains an important cause of cancer-related death. Nanosecond pulsed electric fields (nsPEFs) are advantageous in the treatment of melanoma and pancreatic cancer, but their therapeutic application on liver tumors need to be further studied.

Methods: Hep3B cells were treated with nsPEFs.

The latest research progress on minimally invasive treatments for hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide. Due to the high prevalence of hepatitis B virus (HBV) infection in China, the incidence of HCC in China is high, and liver cirrhosis caused by chronic hepatitis also brings great challenges to treatment. This paper reviewed the latest research progress on minimally invasive treatments for HCC, including percutaneous thermal ablation and new nonthermal ablation techniques, and introduced the principles, advantages, and clinical applications of various therapeutic methods in detail.

Development and preliminary testing of a probe-based duplex real-time PCR assay for the detection of African swine fever virus.

An outbreak of African swine fever (ASF) in China in 2018 caused substantial economic losses to the swine industry. To accurately diagnose clinical infection with ASF virus (ASFV), we developed a TaqMan probe-based duplex real-time PCR that simultaneously detected two discontinuous genes in the virus genome, thereby preventing the inaccurate results obtained with only one reaction. Two sets of ASFV gene-specific primers, along with two fluorescent TaqMan probes were designed to target conserved regions of the B646L and B438L genes.

Pollution characteristics, spatial variation, and potential risks of phthalate esters in the water-sediment system of the Yangtze River estuary and its adjacent East China Sea.

Spatiotemporal variability in seawater, spatial variation in sediment, pollution characteristics, and risks related to 16 phthalate esters (PAEs) were investigated in the Yangtze River estuary and its adjacent East China Sea. The total concentrations of ΣPAEs in surface water were 0.588-17.

Phthalic acid esters in the sea-surface microlayer, seawater and sediments of the East China Sea: Spatiotemporal variation and ecological risk assessment.

The spatial and temporal distribution, congener profiles and ecological risk of phthalic acid esters (PAEs) were investigated in the seawater and sediment samples from the East China Sea in spring and autumn. The average concentrations of ΣPAEs in water samples were 3.16 ± 2.

Distribution and ecotoxicological state of phthalate esters in the sea-surface microlayer, seawater and sediment of the Bohai Sea and the Yellow Sea.

The spatial distribution, chemical composition and ecological risk of 16 phthalate esters (PAEs) were investigated in the sea-surface microlayer (SML), seawater and sediment samples of the Bohai Sea (BS) and the Yellow Sea (YS). The concentration levels of the ΣPAEs spanned a range of 449-13441 ng L in the SML, 453-5108 ng L in seawater, and 1.24-15.
