Lorlatinib for the treatment of anaplastic lymphoma kinase-positive non-small cell lung cancer.

Approximately 3-5% of patients with non-small cell lung cancer （NSCLC）belonged to anaplastic lymphoma kinase (ALK)-positive NSCLC. The treatment drugs of ALK-positive NSCLC mainly included crizotinib, ceritinib, alectinib, and brigatinib. Although these drugs had some effects, most of them were usually easy to develop drug resistance.

Influence of Nutritional Status on the Absorption of Polyphyllin I, an Anticancer Candidate from Paris polyphylla in Rats.

Background And Objectives: Protein-calorie malnutrition (PCM) is one of the most suffered complications in cancer patients. Polyphyllin I (PPI), a saponin isolated from rhizome of Paris polyphylla, is a potential candidate in cancer therapy. In this study, the influence of nutritional status on the absorption of PPI in rats was explored after oral administration.

A high-throughput screening strategy for accurate quantification of menaquinone based on fluorescence-activated cell sorting.

To enhance the screening efficiency and accuracy of a high-yield menaquinone (vitamin K2, MK) bacterial strain, a novel, quantitative method by fluorescence-activated cell sorting (FACS) was developed. The staining technique was optimized to maximize the differences in fluorescence signals between spontaneous and MK-accumulating cells. The fluorescence carrier rhodamine 123 (Rh123), with its ability to reflect membrane potential, proved to be an appropriate fluorescent dye to connect the MK content with fluorescence signal quantitatively.

DuraLith geopolymer waste form for Hanford secondary waste: correlating setting behavior to hydration heat evolution.

The binary furnace slag-metakaolin DuraLith geopolymer waste form, which has been considered as one of the candidate waste forms for immobilization of certain Hanford secondary wastes (HSW) from the vitrification of nuclear wastes at the Hanford Site, Washington, was extended to a ternary fly ash-furnace slag-metakaolin system to improve workability, reduce hydration heat, and evaluate high HSW waste loading. A concentrated HSW simulant, consisting of more than 20 chemicals with a sodium concentration of 5 mol/L, was employed to prepare the alkaline activating solution. Fly ash was incorporated at up to 60 wt% into the binder materials, whereas metakaolin was kept constant at 26 wt%.

Biological reduction of uranium--from the laboratory to the field.

The chemical and biological processes underlying in situ bioremediation of uranium-contaminated groundwater have been studied in the laboratory and in the field. This article focuses on the long-term stability of uraninite (UO(2)) in the underground. A large tailings pond, 'Dänkritz 1' in Germany, was selected for this investigation.
