Remote Sensing Analysis and LiDAR Experimenting in the Espique Valley (La Peza, Granada, Spain)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The Espique valley is a small space at the foot of the mountain, practically closed, which hides a rich archaeological heritage, not only of habitats but also of varied productive spaces. For some years now, MEMOLab UGR has been carrying out research that is now enriched with the contribution of LiDAR, with whose application we are ...

The expression of CTLA-4 in hepatic alveolar echinococcosis patients and blocking CTLA-4 to reverse T cell exhaustion in Echinococcus multilocularis-infected mice

open access: yesFrontiers in Immunology
Alveolar echinococcosis (AE) is a zoonotic parasitic disease caused by the infection of Echinococcus multilocularis (E. multilocularis) larvae. Cytotoxic T-lymphocyte antigen 4 (CTLA-4) produces inhibitory signals and induces T cell exhaustion, thereby ...

Novel Sulfonylhydrazones With Sulfonate Ester Framework: Promising Dual Inhibitors of AChE and hCAs

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disorder that affects millions of individuals worldwide. Treatment strategies for AD vary depending on cognitive and behavioral symptoms, with cholinergic replacement therapy using acetylcholinesterase (AChE) inhibitors being one of the primary approaches.

Biochar‐based fertilizers increase crop yields in acidic tropical soils

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Depletion of soil organic carbon and nutrients creates mounting challenges for agricultural production in tropical regions, putting livelihoods and food security at risk. Biochar‐based fertilizer (BBF) has been suggested as a tool to maintain yields while concurrently improving soil organic carbon content and related soil functions. This study
