Intracellular morphogenesis of diatom silica is guided by local variations in membrane curvature.

Silica cell-wall formation in diatoms is a showcase for the ability of organisms to control inorganic mineralization. The process of silicification by these unicellular algae is tightly regulated within a membrane-bound organelle, the silica deposition vesicle (SDV). Two opposing scenarios were proposed to explain the tight regulation of this intracellular process: a template-mediated process that relies on preformed scaffolds, or a template-independent self-assembly process.

Hexagonal Patterns in Diatom Silica Form via a Directional Two-Step Process.

Organisms are able to control material patterning down to the nanometer scale. This is exemplified by the intricate geometrical patterns of the silica cell wall of diatoms, a group of unicellular algae. Theoretical and modeling studies propose putative physical and chemical mechanisms to explain morphogenesis of diatom silica.

Comparative genomic analysis identifies potential adaptive variation in .

is associated with respiratory disease in wild and domestic Caprinae globally, with wide variation in disease outcomes within and between host species. To gain insight into phylogenetic structure and mechanisms of pathogenicity for this bacterial species, we compared genomes for 99 samples from 6 countries (Australia, Bosnia and Herzegovina, Brazil, China, France and USA) and 4 host species (domestic sheep, domestic goats, bighorn sheep and caribou). Core genome sequences of assemblies from domestic sheep and goats fell into two well-supported phylogenetic clades that are divergent enough to be considered different bacterial species, consistent with each of these two clades having an evolutionary origin in separate host species.

Sulforaphane suppresses bladder cancer metastasis via blocking actin nucleation-mediated pseudopodia formation.

Metastasis is the primary stumbling block to the treatment of bladder cancer (BC). In order to spread, tumor cells must acquire increased migratory and invasive capacity, which is tightly linked with pseudopodia formation. Here, we unravel the effects of sulforaphane (SFN), an isothiocyanate in cruciferous vegetables, on the assembly of pseudopodia and BC metastasis, and its molecular mechanism in the process.

Association between Diet Quality and Eating Behavior in Type 2 Diabetes Adults: A Cross-Sectional Study.

Type 2 diabetes mellitus (T2DM) has become a global epidemic. To effectively control T2DM, individuals must adhere to a high-quality diet that encompasses not only healthy dietary patterns but also promotes positive eating behaviors. We conducted a cross-sectional study on 314 patients with T2DM, and we evaluated the diet quality and also examined the associations between eating behavior, diet quality, and anthropometric and clinical factors in T2DM patients.
