A structurally novel metabolite, fatuamide A (), was discovered from a laboratory cultured strain of the marine cyanobacterium sp., collected from Faga'itua Bay, American Samoa. A bioassay-guided approach using NCI-H460 human lung cancer cells directed the isolation of fatuamide A, which was obtained from the most cytotoxic fraction.

The characterization of phenotypes in cells or organisms from microscopy data largely depends on differences in the spatial distribution of image intensity. Multiple methods exist for quantifying the intensity distribution - or image texture - across objects in natural images. However, many of these texture extraction methods do not directly adapt to 3D microscopy data.

Catalytic elimination through an oxidative decomposition pathway is the most promising candidate for the purification of chlorinated volatile organic compound (CVOC) pollutants, but the complicated mechanisms and the formation pathways of hydrogenated byproducts still need to be clearly revealed. Herein, W/ZrO, as a structure-tunable catalyst, is used to catalytically oxidize dichloromethane (DCM) and clarify the formation pathway of monochloromethane (MCM). Crystal engineering of ZrO tailors surface WO species; practically, the predominant Zr-WO clusters and crystalline WO can be obtained on monoclinic (m-ZrO) and tetragonal (t-ZrO) phases.

Plants are colonized by a vast array of microorganisms that outstrip plant cell densities and genes, thus referred to as plant's second genome or extended genome. The microbial communities exert a significant influence on the vigor, growth, development and productivity of plants by supporting nutrient acquisition, organic matter decomposition and tolerance against biotic and abiotic stresses such as heat, high salt, drought and disease, by regulating plant defense responses. The rhizosphere is a complex micro-ecological zone in the direct vicinity of plant roots and is considered a hotspot of microbial diversity.

Background: Self-management behaviors can prevent the negative consequences among patients with coronary heart disease (CHD). The reality of patients followed the self-management behaviors rate are unoptimistic.
Objective: This study aimed to examine whether self-efficacy serves as a mediating role between family functioning and self-management behaviors among coronary heart disease patients.
