“新冠肺炎”抗疫中使用的重要高分子材料

Polymeric materials played an important role in the battle against novel corona virus epidemic. These materials can be seen everywhere not only from the conventional protective masks to professional protective equipment, but also from the expensive extracorporeal membrane oxygenation (ECMO) to the rapid construction of the Huoshenshan and Leishenshan Hospital. In this paper, the synthesis, processing and manufacture of these polymeric materials are introduced from the viewpoint of polymer chemistry, polymer physics and polymer processing, with emphasis on the important role of these materials in the battle against the COVID-19 epidemic.     

Granulocyte luminescence curves: Is anything there?

This problem (proposed for the 4th International Symposium on Applied Stochastic Models and Data Analysis) concerns an exploratory study related to the presently accepted hypothesis that temporal curves of the forced pulse luminescence of specialized blood cells, granulocytes, may indicate the level of effectiveness of the immunological system. This paper presents a new set of empirical data and an analysis of its structure.

The crystal and molecular structure of dl-BI-(o-trimethyl-cis-brazilane)

X-ray crystallographic analysis has established the crystal and molecular structure of the title compound, C₃₈H₃₈O₈. The monoclinic crystals belong to the centrosymmetric space group P2₁/c, with a = 16.701(5), b = 8.037(2), c = 23.600(9) Å, β = 93.10(2)° and Z=4. The structure was solved by direct methods from diffractometer data measured with CuKα radiation, and refined to a final R index of 0.081 for the 2088 observed terms. The dimeric molecule has approximate two-fold symmetry and its presence in the unit cell in both chiralities forms a racemic structure. The three central bonds, C(10)-C(11), C(11)-C'(11), C'(11)-C'(10), are significantly elongated with a mean value 1.59 Å.     

Regulatory compliance vs. NEXUS quality for laboratory tests

In the U.S., all clinical laboratory testing is regulated by the Clinical Laboratory Improvement Amendments (CLIA) (). The CLIA link test quality and adherence to a body of testing regulations intended to ensure accurate, reliable, and timely patient test results. The goal of the CLIA legislation was to ensure a minimum, fundamental level of quality. In the context of “NEXUS,” quality must “go beyond getting the ‘right’ answer on the ‘right’ patient that can be interpreted against ‘right’ reference values. CLIA regulations with specific minimum, performance requirements, or safeguards, are designed to prevent testing errors. The US Institute of Medicine found that testing processes fail as a result of human error, lack of documentation, and lack of test management. In the latest (2004) interpretations of CLIA regulations, the minimum quality control requirement continues to be analyzing at least two external, liquid quality control materials per test per day. In 1995, we proposed that the responsibility for achieving quality test results shifts from the sole purview of the laboratory director to an “alliance” of laboratory professionals, manufacturers, and regulators. The EQC (equivalent quality control) concept as proposed is a positive step in achieving this alliance. With the obvious lack of scientific and statistical robustness, EQC falls far short of ensuring quality. Achieving the “NEXUS Vision” for quality laboratory testing will not come solely from laboratory professionals. The NEXUS is about how to ensure the full-quality assessment of the testing process – pre-analytical, analytical, and post-analytical.Presented at the 10th Conference Quality in the Spotlight, March 2005, Antwerp, Belgium.
