We have developed a time-dependent computational framework, HEDOS (HEmatological DOSe), to estimate dose to circulating blood cells from radiation therapy treatment fields for any treatment site. Two independent dynamic models were implemented in HEDOS: one describing the spatiotemporal distribution of blood particles (BPs) in organs and the second describing the time-dependent radiation field delivery. A whole-body blood flow network based on blood volumes and flow rates from ICRP Publication 89 was simulated to produce the spatiotemporal distribution of BPs in organs across the entire body using a discrete-time Markov process...

OBJECTIVES: To test the effect of traditional up-sampling slice thickness (ST) methods on the reproducibility of CT radiomics features of liver tumors and investigate the improvement using a deep neural network (DNN) scheme. METHODS: CT images with ≤ 1 mm ST in the public dataset were converted to low resolution (3 mm, 5 mm) CT images. A DNN model was trained for the conversion from 3 mm-ST and 5 mm-ST to 1 mm-ST and compared with conventional interpolation-based methods (cubic, linear, nearest) using structural similarity (SSIM) and peak-signal-to-noise-ratio (PSNR)...

BACKGROUND: A prediction model for overall survival (OS) in metastatic pancreatic ductal adenocarcinoma (PDAC) including patient and treatment characteristics is currently not available, but it could be valuable for supporting clinicians in patient communication about expectations and prognosis. We aimed to develop a prediction model for OS in metastatic PDAC, called SOURCE-PANC, based on nationwide population-based data. MATERIALS AND METHODS: Data on patients diagnosed with synchronous metastatic PDAC in 2015 through 2018 were retrieved from the Netherlands Cancer Registry...

Autoimmune phenomena and clinically apparent autoimmune diseases, including autoimmune hepatitis, are increasingly been reported not only after natural infection with the SARS-CoV-2 virus, but also after vaccination against it. We report the case of a 63-year old man without a history of autoimmunity or SARS-CoV-2 natural infection who experienced acute severe autoimmune-like hepatitis seven days after the first dose of the mRNA-1273 SARS-CoV-2 vaccine. Liver histology showed inflammatory portal infiltrate with interface hepatitis, lobular and centrilobular inflammation with centrilobular necrosis, in absence of fibrosis and steatosis...

In order to explore the mechanism of liver injury induced by florfenicol (FFC) in broilers. Sixty broilers were randomly divided into 2 groups: control group: normal drinking water and feed were given every d; FFC group: tap water containing FFC (0.15g/L) was given every d and feed was taken freely; each group was given 5 dd of continuous medication and feed was taken freely. The results showed that compared with the control group, FFC could significantly inhibit the weight gain of broilers (P < 0.05), and significantly inhibit the expression of CYP1A1 and CYP2H1 in liver tissue (P < 0...

T cells of aged people, and of patients with either cancer or severe infections (including COVID-19), are often exhausted, senescent and dysfunctional, leading to increased susceptibilities, complications and mortality. Neurotransmitters and Neuropeptides bind their receptors in T cells, and induce multiple beneficial T cell functions. Yet, T cells of different people vary in the expression levels of Neurotransmitter and Neuropeptide receptors, and in the magnitude of the corresponding effects. Therefore, we performed an individual-based study on T cells of 3 healthy subjects, and 3 Hepatocellular Carcinoma (HCC) patients...

Perfluorooctanoic acid (PFOA) is an environmental pollutant that has multiple toxic effects. Although some medicines and functional food ingredients are currently being used to alleviate the biological toxicity effects caused by PFOA, these candidates all show potential side effects and cannot prevent the accumulation of PFOA in the body, making them unable to be used as a daily dietary supplement to relieve the toxic effects of PFOA. However, new research has shown that lactic acid bacteria (LAB) can alleviate toxicity caused by exposure to foreign substances...

In alcoholic liver disease (ALD) research, animal models, as one of the most popular methods to explore pathology and therapeutic drug screening, show the limitations of expensive cost and ethic, as well as long modeling time. To minimize the use of animal models in ALD research, an artificial liver model has been developed by incorporating HepG2 cells into hydrogel matrix based on difunctional hyaluronan and collagen. And on this basis an alcohol-induced ALD model in vitro by adding alcohol in the engineering process has been established...

Decabromodiphenyl ethane (DBDPE) is one of the most commonly used novel brominated flame retardants (NBFRs), and its mass production and widespread application have caused health threats to the human being. Existing studies have shown that DBDPE has hepatotoxicity. And we have found that DBDPE could change cytochrome P450 3A (CYP3A) expression levels in rat livers, whereas the mechanism is unclear. In this study, we exposed human normal hepatocyte (L-02) to DBDPE to further study the effect and mechanism of DBDPE on hepatocellular injury and liver metabolic enzyme CYP3A changes in vitro...

As the occurrence and development of HCC are often accompanied by inflammation, the combination of sorafenib with other therapeutic drugs, especially anti-inflammatory drugs, is one of the directions to be explored at present. Our previous research has been focused on the anti-inflammatory drug 2,5-dimethylcelecoxib (DMC), whether DMC combined with sorafenib could elevate the effect of inhibiting HCC deserves further exploration. In this study, we found that DMC induced CYP3A5 expression in HCC cells in a time-dependent and concentration dependent manner...

Oxidative damage and intestinal dysbiosis are regarded as crucial culprits in alcoholic liver disease (ALD). This study aimed to examine the protective effects of Echinacea purpurea polysaccharides (EPPs) against ALD and explore the underlying mechanisms based on hepatic oxidative stress, inflammation, and intestinal barrier function. Three polysaccharide fractions, namely, EPP40, EPP60, and EPP80, were obtained by stepwise ethanol precipitation, and their antioxidant activity in vitro was investigated. The results showed that EPP80 with Mw 11...

Psoriasis is associated with a higher risk of liver diseases. We investigated the impact of hepatic steatosis (European cohort) and hepatic inflammation (United States cohort) on subclinical atherosclerosis. In the European cohort (n=76 psoriasis participants and 76 controls), non-alcoholic fatty liver disease (NAFLD), assessed by the sonographic hepatorenal index (SHRI), was more prevalent in psoriasis than controls (61% vs 45%; p=.04). Psoriasis participants with NAFLD had a higher prevalence of subclinical atherosclerosis (ultrasonographic presence of plaque in femoral or carotid arteries) than psoriasis without NAFLD (61% vs 23%; p=...

Reduced exercise tolerance (whole body peak oxygen uptake, VO2 ) is a hallmark feature of both heart failure (HF) and cirrhosis1,2 . By the Fick equation, whole body peak VO2 is the product of cardiac output (central component) and O2 extraction (i.e., the arteriovenous O2 difference, peripheral component). In HF, multiple studies have described the important contributions of central and peripheral components to reduced peak VO2 3,4 .
