Velocity structure tomography analysis in southern Hebei Province

open access: yes地震科学进展
The destruction of cratons is one of the key research objects of geophysicists. According to China Earthquake Networks Center, small and medium-sized earthquakes have occurred more frequently in southern Hebei in recent years than before.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Organically bound tritium in sediments from the Severn Estuary, UK [PDF]

open access: yes, 2006
Amersham plc, now GE Healthcare, has discharged both organically bound tritium (OBT) and tritiated water (HTO) into the Severn estuary since 1981. The OBT component of these discharges results in elevated tritium (3H) activities in the sediments and ...

Degradation of Hydrocarbons and Heavy Metal Reduction by Marine Bacteria in Highly Contaminated Sediments

open access: yesMicroorganisms, 2020
Investigations on the ability of bacteria to enhance removal of hydrocarbons and reduce heavy metal toxicity in sediments are necessary to design more effective bioremediation strategies. In this study, five bacterial strains, Halomonas sp.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Determination of the source location of the 2023 Jishishan M6.2 earthquake in Gansu Province

open access: yes地震科学进展
Based on the P-phase arrival time, we determined the source location of the Jishishan M6.2 earthquake with simulated annealing (SA) method, and quantitatively evaluated the reliability of the results using sample set statistical analysis method.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

open access: yesFEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Iron inputs from sediments to the oceans [PDF]

open access: yes, 2009
This thesis explores the nature and ubiquity of iron (Fe) inputs from sediments to theoceans. In the last 10 years continental shelf sediments have become widely recognisedas important vectors for dissolved Fe inputs to the oceans, where bacterial ...

Analysis of the anomalous characteristics of the solid tide modulation ratio before the Linfen,Shanxi M4.1 and M4.2 earthquakes in 2025

open access: yes地震科学进展
The starting magnitude is one of the core parameters that determine the scanning results of the solid tide modulation ratio. Currently, the modulation ratio scanning analysis of solid tides is mostly based on a single, specific magnitude as the benchmark,
