Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

open access: yesFEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Distribution of trace and toxic element monitoring in soil samples from the lesser Himalayan region of India, pollution indices and source identification

open access: yesDiscover Environment
Monitoring toxic and trace elements in soil is vital for environmental protection, agricultural productivity, and regulatory compliance, yet tailored methodologies for comprehensive soil analysis are limited, particularly in ecologically sensitive ...

Environmental monitoring in heterogeneous soil-landscapes; A Dutch case study

open access: yes, 2010
The spatial heterogeneity of agricultural soil-landscapes is mostly not taken into account in environmental policies. Most environmental goals have been defined at national level or farm level but not at the landscape level.

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

open access: yesFEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

High-Resolution Mapping and Biomass Estimation of Suaeda salsa in Coastal Wetlands Using UAV Visible-Light Imagery and Hue Angle Inversion

open access: yesApplied Sciences
Unmanned Aerial Vehicles (UAVs) have become powerful tools for high-resolution, quantitative remote sensing in ecological and environmental studies. In this study, we present a novel approach to accurately mapping and estimating the biomass of Suaeda ...

The complete mitochondrial genome of Helice Sheni and its phylogenetic implication

open access: yesMitochondrial DNA. Part B. Resources, 2018
In this study, the complete mitochondrial genome (mitogenome) of Helice sheni was amplified and analyzed. The mitogenome is 16,062 bp in length, encoding the standard set of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and one control region ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Characterization of the complete mitochondrial genome of Eriocheir leptognathus with phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2019
Eriocheir leptognathus is a dominant species in the Yangtze River estuary. In this study, we first determined the complete mitochondrial genome (mitogenome) of E. leptognathus. The mitogenome is 16,143 bp in length, consisting of 13 protein-coding genes (

Soil acidification monitoring in the Netherlands

open access: yes, 2002
The last decades of the 20th century are characterized by a vast increase in activities developed and measures taken by the authorities to accommodate the fear of environmental problems that boomed since the late 1960s.
