Additionally, a unique histological change called goblet cell metaplasia was found in the ENS group. The respiratory epitheliums of ENS were mostly intact with preservation of ciliated cells and goblet cells. The ENS group had a significantly lower expression level of TRPM8. CONCLUSIONS The nasal mucosa of ENS experienced some airway remodeling and thermoreceptors downregulation, which contribute to clinical symptoms. The distinct histology of ENS included preserved respiratory epithelium and goblet cell metaplasia, accompanying with characteristics similar to atrophic rhinitis. Biopsy of the inferior turbinate may help diagnose ENS.

In order to further utilize the byproducts of aquatic shellfish (Pinctada martensii meat) with high value, this study proposes a method of extracting zinc and taurine from P. martensii meat. Zinc was first extracted from P. martensii meat with an ultrasonic crusher, and then taurine was further extracted by ultrasonic-assisted water extraction from the remaining shellfish. After optimization, the biological zinc extraction rate reached 8.63%, and the taurine extraction rate reached 0.71%. Meanwhile, the parameters for cation exchange separation and taurine purification were optimized, in which the injection volume, pH value, and elution rate were set to 8.0 mL, 4.5, and 3.0 mL/min, respectively. selleck compound Ultimately, the purity the extracted taurine reached 98.16%. This study provides a novel method for the extraction of biological zinc and taurine by deep processing of shellfish meat. © 2020 Institute of Food Technologists®.BACKGROUND The current study was performed to investigate whether circulating cell-free Epstein-Barr virus DNA (cfEBV DNA) would be useful for posttreatment surveillance in patients with nasopharyngeal carcinoma (NPC). METHODS The authors identified a total of 1984 nondisseminated NPC patients from an institutional big-data research platform. Blood samples were collected within 3 months of the completion of radiotherapy and every 3 to 12 months thereafter for cfEBV DNA analysis. Patients were followed until disease recurrence was detected or for a median of 60 months. Diagnostic performance was assessed by calculating the sensitivity, specificity, and accuracy based on the clinical detection of disease recurrence by conventional surveillance modalities (imaging scans and pathological examination). RESULTS During follow-up, a total of 767 patients (38.7%) had detectable cfEBV DNA. The recurrence rate among these patients was 63.8% (489 of 767 patients), which was significantly higher than that in patients with extrapulmonary metastases. © 2020 American Cancer Society.In the present work we study the photodynamic action of cercosporin (cerco), a naturally occurring photosensitizer, on human cancer multicellular spheroids. U87 spheroids exhibit double the uptake of cerco than T47D and T98G spheroids as shown by flow cytometry on the single cell level. Moreover, cerco is efficiently internalized by cells throughout the spheroid as shown by confocal microscopy, for all three cell lines. Despite their higher cerco uptake, U87 spheroids show the least vulnerability to cerco-PDT, in contrast to the other two cell lines (T47D and T98G). While 300 μm diameter spheroids consistently shrink and become necrotic after cerco PDT, bigger spheroids (>500 μm), start to re-grow following blue-light PDT and exhibit high viability. Cerco-PDT was found to be effective on bigger spheroids reaching 1mm in diameter especially under longer exposure to yellow light (~590 nm). In terms of metabolism, T47D and T98G undergo a complete bioenergetic collapse (respiration and glycolysis) as a result of cerco-PDT. U87 spheroids also experienced a respiratory collapse following cerco-PDT, but retained half their glycolytic activity. This article is protected by copyright.

Pathological data distributions that exhibit skewness and zero-inflation complicate these tasks-requiring highly flexible, data-adaptive modeling. In this paper, we present a multipurpose Bayesian nonparametric model for continuous, zero-inflated outcomes that simultaneously predicts structural zeros, captures skewness, and clusters patients with similar joint data distributions. The flexibility of our approach yields predictions that capture the joint data distribution better than commonly used zero-inflated methods. Moreover, we demonstrate that our model can be coherently incorporated into a standardization procedure for computing causal effect estimates that are robust to such data pathologies. Uncertainty at all levels of this model flow through to the causal effect estimates of interest-allowing easy point estimation, interval estimation, and posterior predictive checks verifying positivity, a required causal identification assumption. Our simulation results show point estimates to have low bias and interval estimates to have close to nominal coverage under complicated data settings. Under simpler settings, these results hold while incurring lower efficiency loss than comparator methods. We use our proposed method to analyze zero-inflated inpatient medical costs among endometrial cancer patients receiving either chemotherapy or radiation therapy in the SEER-Medicare database. © 2020 The International Biometric Society.Good sun-safety practice includes wearing sun-protective hats that must meet defined photoprotective criteria such as the 2017 Australian/New Zealand standard (AS/NZS 43992017). This study investigated the availability of sun-safe hats during a three-day cross-sectional survey in November 2019 by visiting every shop in a single large multi-store shopping complex in Australia. Hats were categorised according to whether the target customer was an adult or child prior to the assessment of design suitability for sun safety according to the standard. Of the 260 shops in the study shopping centre, 30 (12 %) sold hats. Of the 524 hats examined in the study, 69 % of all commercially available hats for adults and children did not meet the standard. Of the 9 % of hats that had swing tags claiming an Ultraviolet Protection Factor of 50 (UPF-50), about half were not sun safe. Further research is needed to investigate the possibility of whether sun-safety hat standards should be given to retailers of hats for display, or whether manufacturers could be required to put warning labels on all hats that do not meet sun-safety hat standards.
