Trophic gradients of two minnow species with similar eco-type and their relations to water chemistry and multimetric biological integrity

Journal of Asia-Pacific Biodiversity, 2017
The objectives of this study were to determine tolerance ranges and trophic gradients of two fish populations of Zacco koreanus (Zk) and Zacco platypus (Zp) in relation to chemical water quality and ecological stream health, based on the biological ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Chemical-equilibrium-based Method for Calculating Multicomponent Dissolved Corrosion Product Distributions in Bulk-flow Regions of PWR Core Sub-channels

Yuanzineng kexue jishu
Oxidized corrosion products in pressurized water reactors (PWRs) deposit on fuel rods to form an oxide corrosion-product deposit layer, which threatens the safety and economic performance of nuclear power plants.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Assemblage of aquatic hyphomycetes and their colonization of leaf litter in a tropical lateritic cave stream

MycoAsia - Journal of Modern Mycology
Investigations on occurrence of aquatic hyphomycetes in lateritic cave streams in India are meager. This study examined the assemblage, diversity and leaf litter colonization of aquatic hyphomycetes in a cave stream in southwest India.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
