Arsenic in the flue gas has been widely reported as a common poison for SCR catalysts; however, an appropriate coping strategy is still lacking to improve the arsenic resistance performance. Herein, a unique AsO/CeO interface is constructed to transform arsenic from poison into active site with balanced acid-redox property, successfully achieving efficient NO removal. The optimized AsO/CeO exhibits high NO removal efficiency, four times that of the As-poisoned VO/TiO catalyst, and even comparable to the state-of-the-art SCR catalysts.

Objective: To identify socioeconomic factors influencing the presentation and outcomes of cutaneous head and neck squamous cell carcinoma (cHNSCC).
Study Design: Retrospective cohort study.
Setting: Tertiary academic medical center with comprehensive cancer center.
Objectives: Variceal hemorrhage is a fatal complication of cirrhosis. In this study, we aimed to investigate the role of serum interleukin 2 receptor (sIL-2R) as a predictive indicator in patients with a previous history of cirrhosis-related variceal bleeding.
Methods: A total of 340 cirrhotic patients who had experienced variceal bleeding from December 2016 to December 2018 were enrolled, and were randomly assigned to the modeling group and the validation group.
The commercial VO -WO/TiO (VWTi) catalysts often suffer from a serious joint deactivation by multiple heavy metals in the flue gas for NO removal by NH-SCR. Herein, we report an extraordinary deactivation offset effect between Zn and As on VWTi with alleviation of the toxic effects of the heavy metals by "like cures like". With the As&Zn content of 4 wt%, VWTi-As&Zn exhibited over 97% NO conversion under a GHSV of 100,000 h and good SO/HO tolerance (> 93% NO conversion).

Machine learning, which has achieved dramatic success in a wide range of applications, holds the promise to bring unprecedented perspectives for this challenging task. However, despite the exciting progress made along this direction, the reliability of machine-learning approaches in experimental settings demands further investigation.

In this study we aimed to explore the practice patterns of Chinese practitioners in GV treatment and discuss whether these patterns conform to the guidelines in China and around the world.

Extramammary Paget disease can precede or occur along with internal malignant neoplasms.
Objective: To develop recommendations for the care of adults with EMPD.
Background: Optimal surgical treatment modality for invasive melanoma (IM) and melanoma in situ (MIS) has been debated with proponents for standard wide local excision (WLE), serial disk staged excision, and Mohs micrographic surgery.
Objective: The purpose of this study is to identify the recurrence rates and surgical margins of invasive stage 1 melanoma and MIS lesions using serial disk staged excision technique with rush permanent processing and "bread loafing" microscopic analysis.
Materials And Methods: Recurrence rates and surgical margins of 63 IM and 207 MIS at the University of California Dermatology Surgery Unit were retrospectively reviewed.

Background: Sweet's syndrome (SS), also known as acute febrile neutrophilic dermatosis, is a rare neutrophilic dermatitis characterized by pyrexia, neutrophilia and painful papulonodular lesions with a neutrophilic dermal infiltrate.
Case Presentation: We presented a case report of classical SS associated with ulcerative colitis (UC) and mucosal prolapse polyps (MPPs) in a male patient.
Conclusions: The particularity of this case is the occurrence of MPPs in a male patient with UC and classical SS.

Fusarium species represent a range of fungal pathogens capable of causing diverse mycotic diseases. Relative to antibacterial drugs, few effective antifungal agents have been developed to date, and all are subject to significant limitations. As such, there is an urgent need to design novel antifungal treatments for infections caused by Fusarium spp.

Health support has been sought by the public from online social media after the outbreak of novel coronavirus disease 2019 (COVID-19). In addition to the physical symptoms caused by the virus, there are adverse impacts on psychological responses. Therefore, precisely capturing the public emotions becomes crucial to providing adequate support.

Data regarding concordance between BCC subtype on initial biopsy and final histopathology for Mohs micrographic surgery (MMS) or excision with frozen sections (EFS) are limited.
Objectives: To determine the concordance between initial biopsy and final MMS or EFS subtyping of BCC.
Infections are a major complication of obesity, but the mechanisms responsible for impaired defense against microbes are not well understood. Here, we found that adipocyte progenitors were lost from the dermis during diet-induced obesity (DIO) in humans and mice. The loss of adipogenic fibroblasts from mice resulted in less antimicrobial peptide production and greatly increased susceptibility to infection.

This strategy involves sequential inert C-H/C-H functionalizations through intermolecular addition reaction of oxyalkyl radicals to -cyano groups followed by radical cyclization of iminyl radicals generated with C-2 aryl rings. This method allows for efficient synthesis of tetracyclic benzo[4,5]imidazo[1,2-]quinazolines.

The deactivation of selective catalytic reduction (SCR) catalysts by arsenic is a serious problem for NH-SCR. However, it is tough to design catalysts with good resistance to arsenic compared to other poisons such as alkali metal, SO, etc., because As not only deteriorates surface acidity but also redox property, causing excessive NO generation.
