Oxygen vacancy-rich K-MnO@CeO catalyst for efficient oxidation degradation of formaldehyde at near room temperature.

Synthesis of catalysts with high catalytic degradation activity for formaldehyde (HCHO) at room temperature is highly desirable for indoor air quality control. Herein, a novel K-MnO@CeO catalyst with excellent catalytic oxidation activity toward HCHO at near room temperature was reported. In particular, the K addition in K-MnO@CeO considerably enhanced the oxidation activity, and importantly, 99.

Nanopore sequencing of cerebrospinal fluid of three patients with cryptococcal meningitis.

Background: Cryptococcal meningitis (CM) has a high morbidity and mortality due to the low detection of Cryptococcus in cerebrospinal fluid (CSF) during the early stage of the disease with traditional methods.

Case Presentation: In addition to the traditional methods of India ink staining and cryptococcal antigen (CrAg), we used nanopore sequencing and next-generation sequencing (NGS) to detect pathogenic DNA in CSF samples of three patients with CM. The CSF samples of all three patients were positive by India ink staining and CrAg.
