Matrix of energy-specific PN dose equivalents was obtained demonstrating that the Sohrabi neutron dosimetry methods applied are unique for energy-specific PN dose equivalent studies as well as for 360°angular PN dose equivalent distribution data for PN-SPC risk estimation. The dosimetry methods can be specifically applied to many other exotic applications in health physics, medical physics, space flight dosimetry, and nuclear science and technology.

It is of great significance to monitor ROS in biological organs to further study oxygen metabolism. Herein, an ultrasensitive sensing platform is developed with electrochemiluminescent (ECL) signalling by integrating bioactive magnetic beads (BMBs) on indium tin oxide (ITO) coated glass using a magnet. For the first time, AuNPs were successfully deposited on Fe3O4 NPs in situ by reduction of α-ketoglutaric acid (α-KG), therefore the electroactive protein, haemoglobin (Hb) or cytochrome C (Cyt C), was assembled on via covalent bonds. The protein can realize direct electron transfer (DET) and catalyse the redox of ROS, reaching a detection limit of 6.21 μM or 0.6 μM of H2O2. Also Au@Fe3O4 NPs efficiently enhanced the ECL of luminol, promoting the sensing ability for ROS. This simultaneous effect endows the platform with low LOD of ROS for 7.69 nM (Hb), or 1.97 nM (Cyt C). Finally, the feasibility and practicality of the sensing platform were verified by monitoring the ROS released from mouse myocardial tissue.
Evidence suggests that non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) have antineoplastic properties of potential importance for survival of head and neck cancer.

We conducted a nationwide cohort study including all individuals with primary head and neck squamous cell carcinoma in Denmark during 2000-2016 at age 30-84 years, with no history of cancer (except non-melanoma skin cancer), and alive at 1 year after diagnosis. Nationwide registries provided information on drug use, causes of death and potential confounders, and additional clinical information was obtained for a subpopulation. We conducted Cox proportional hazards regression to estimate multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for the association between post-diagnosis non-aspirin NSAID use (defined as ≥1 filled prescription within first year after diagnosis) and cancer-specific mortality.

Among 10,770 head and neck cancer 1-year survivors, the HR for cancer-specific mortality with non-aspirin NSAID use was 1.68 at 1 year after diagnosis, but declined and stabilized around 1.15 (95% CI 1.02-1.29) at 2 years after diagnosis. Among 2-year survivors, the HRs for cancer-specific mortality with non-aspirin NSAID use remained slightly increased in analyses stratified by age, sex, stage, and pre-diagnosis non-aspirin NSAID use. Similar results were seen in the subpopulation (n=1029) with additional clinical information, and among 5-year survivors with additional non-aspirin NSAID exposure assessment.

In this nationwide cohort of patients with head and neck cancer, use of non-aspirin NSAIDs was associated with a slightly increased mortality risk, warranting further evaluation.

The platelet inhibitor aspirin reduces inflammation and atherosclerosis in both apolipoprotein E deficient (apoE
) mice and low-density lipoprotein receptor deficient (Ldlr
) mice. Similarly, the factor Xa inhibitor rivaroxaban reduces atherosclerosis in both apoE
and Ldlr
mice. We tested the hypothesis that the combination of aspirin and rivaroxaban reduces atherosclerosis in mice to a greater extent than either agent alone.

Male Ldlr
mice were fed a western-type diet for 12 weeks to induce atherosclerosis. Cohorts of mice received aspirin in the water and/or rivaroxaban in the diet. Atherosclerosis and lesion composition were measured in the aortic sinus and the aorta. Expression of 55 proteins in the aorta and plasma was determined using multiplex ELISA assays.

Aspirin alone, rivaroxaban alone, and the combination of both agents significantly reduced atherosclerosis in the Ldlr
mice compared with control Ldlr
mice fed a western-type diet. However, there were no significant differences in atherosclerosis in the group receiving aspirin and rivaroxaban compared with the groups that received aspirin or rivaroxaban alone. Aspirin, rivaroxaban and the combination reduced macrophage content and apoptosis in the lesions compared with controls but there was no difference between the three treatment groups. We observed statistically significant changes in the expression of a small number of proteins in the aorta and plasma in mice treated with aspirin and/or rivaroxaban.

Contrary to our expectation, the combination of aspirin and rivaroxaban did not further reduce atherosclerosis in Ldlr
mice beyond the level observed with each agent alone.

The regulation of cell-cholesterol efflux is not completely understood. Our aim was to assess the role of HDL- and non-HDL-related parameters in ATP-binding cassette transporter-A1 (ABCA1) and scavenger receptor class B-type-I (SRBI) cell-cholesterol efflux capacity (CEC) in coronary heart disease (CHD) cases and controls.

Lipids and apoA-I-containing HDL particles (by 2D gel-electrophoresis and immunodetection) were measured in 534 statin-treated CHD patients and in 1076 age-, gender-, and BMI-matched controls. ABCA1-CEC and SRBI-CEC were measured in apoB-depleted serum of 100 cases and 100 controls.

Cases had significantly higher concentrations of preβ-1 particles (88%) and ABCA1-CEC (34%) compared to controls. ABCA1-CEC was positively correlated with the concentrations of preβ-1 particles, triglycerides, small-dense (sd) LDL-C, and LDL-C in both cases and controls. Moreover, both the concentration and the functionality of preβ-1 particles (ABCA1-CEC/mg preβ-1) were positively associated with the concentrations of sdLDL-C and triglycerides. Cases had 27% lower levels of large HDL particles but similar SRBI-CEC compared to controls. SRBI-CEC was correlated positively with HDL-C, apoA-I, and large-HDL particle levels. However, the functionality of large-HDL particles (SRBI-CEC/mg large particles) was significantly and positively correlated with the preβ-1/α-1 ratio, sdLDL-C, and triglycerides.

CHD patients have significantly higher concentration, but less functional preβ-1 particles in term of cholesterol efflux capacity compared to controls. Triglyceride-rich lipoproteins have significant influence on either the concentration or the functionality or both of HDL particles and consequently HDL-CEC.

The Alberta Stroke Program Early CT Score (ASPECTS) and hyperdense vessel sign (HDVS) on baseline non-contrast CT (NCCT) may benefit prognosis of acute ischemic stroke (AIS). We aimed to investigate the agreement of ASPECTS between automated and manual interpretations, and further understand the roles of NCCT and CT Perfusion (CTP) in prognosis.

From January 2019 to May 2020, thrombolysis-treated AIS patients undergoing NCCT and Perfusion imaging before treatment were retrospectively reviewed. A radiologist, a senior neuroradiologist and a neurologist blindly interpreted ASPECTS from NCCT images and a prototypical software produced automated results. selleck products Another independent radiologist determined presence of HDVS and CTP-ASPECTS. Three-month modified Rankin scale (mRS)≤2 indicated good functional outcome. NCCT ASPECTS were compared against CTP-ASPECTS using squared weighted kappa. Univariable, multivariable and receiver operating characteristics (ROC) analysis were conducted to evaluate the prognostic value of clinical risk factors, NCCT and CTP findings.

Seventy-five patients were included in this study, of whom 35 (46.7%) presented favorable outcome. Fair to substantial agreement with CTP-ASPECTS was witnessed for automated and manual interpretations (0.685, automated; 0.778, radiologist; 0.830, neuroradiologist; 0.313, neurologist). ASPECTS, HDVS, infarct core volume and mismatch ratio were univariably related to functional outcome, and infarct core volume remained as an independent prognostic factor in the multivariable analysis. The multivariable model achieved an area under ROC (AUC) of 0.768 (95% CI, 0.666-0.870).

Automated ASPECTS achieves substantial agreement with reference CTP-ASPECTS, and comprehensive CT assessment may benefit AIS prognosis after intravenous thrombolysis.

For patients with meningioma, surgical procedures are different because of the status of sinus invasion. However, there is still no suitable technique to identify the status of sinus invasion in patients with meningiomas. We aimed to build a deep learning radiomics model to identify sinus invasion before surgery.

A total of 1048 patients with meningiomas were retrospectively enrolled from two hospitals. T1 enhanced-weighted (T1c) and T2-weighted MRI data for each patient were collected. Tumors and their corresponding peritumors were analyzed. Four ResNet50 models were built with different types of regions of interest (ROIs) (tumor and peritumor) and different modal images (T1c and T2) to predict the status of sinus invasion. Several data enhancement methods were applied before ResNet50 model building. The final model was generated by combining four ResNet50 models.

The models with a combination of tumors and peritumors using multimodal images achieved the highest predictive performance (AUC=0.884, ACC=78.1%) in the independent test cohort. The Delong test proved that the model built with combination ROIs achieved significantly higher performance than the model built only with tumors. The net reclassification improvement and integrated discrimination improvement tests both proved that including peritumor ROIs in the tumor ROIs could significantly improve the prediction ability.

In the current study, the deep learning model showed potential for identifying sinus invasion before surgery in patients with meningioma. Including peritumors could significantly improve predictive performance.
