Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

Removal of Tetracycline from Synthetic Solution by Natural LECA [PDF]

Muhandisī-i Bihdāsht-i Muḥīṭ, 2014
Background: Antibiotic in environment can be accumulated in soil and sediment and then adversely affect the ecosystem function as well as decrease the natural degradation rate of pollutants by producing a antibiotic-resistant microorganisms. The antibiotic-resistant genes can also transfer to drinking water resources and then, leading untreatable human

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Immunological Interactive Effects between Pollen Grains and Their Cytoplasmic Granules on Brown Norway Rats

World Allergy Organization Journal, 2009
Background: Grass pollen is one of the most important aeroallergen vectors in Europe. Under some meteorological factors, pollen grains can release pollen cytoplasmic granules (PCGs). PCGs induce allergic responses.

A practical guide to species trend detection with unstructured data using local frequency scaling (Frescalo)

Ecography, EarlyView.
Accurately measuring biodiversity change remains a central challenge in ecology. Beyond the general idea of quantifying temporal species frequency changes, several sampling‐related biases in data collection remain key methodological challenges to consider. Long‐term standardized ecological data are rare, and most available datasets exhibit considerable

From LUCA to LECA and to the Evolutionary Tree of Life

Natural Science and Advanced Technology Education, 2022
The article analyzes contemporary research on early microbial evolution starting from LUCA (Last universal common ancestor) to the establishment of the two branches of the empire (superkingdom) Prokaryota – Archaea and Bacteria. Under discussion are the basic stages and driving forces of biochemical, physiological and biological evolution of acetogens ...

The contrasted impacts of grasshoppers on soil microbial activities in function of primary production and herbivore diet

Peer Community Journal, 2023
Herbivory can have contrasted impacts on soil microbes and nutrient cycling, which has stimulated the development of conceptual frameworks exploring the links between below- and aboveground processes.

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

Ecography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

‘biomod2' – extending presence–absence species distribution models to multiple data types

Ecography, EarlyView.
The R package ‘biomod2' is one of the most widely used and versatile tools for species distribution modelling (SDM), enabling ecologists to calibrate, evaluate, and project species–environment relationships across space and time using multiple modelling algorithms and ensemble forecasting.
