Comparison of Remote Sensing Estimation Models for Leaf Area Index of Rubber Plantation in Hainan Island

open access: yes智慧农业, 2021
Leaf area index (LAI) is an important index to describe the growth status and canopy structure of vegetation, is of great theoretical and practical significance to quickly obtain LAI of large area vegetation and crops for ecosystem science research and ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Extraction and monitoring of vegetation coverage based on uncrewed aerial vehicle visible image in a post gold mining area

open access: yesFrontiers in Ecology and Evolution, 2023
Vegetation coverage reflects the degree of environmental degradation. Timely and effective monitoring of vegetation conditions is the basis for promoting vegetation protection and improving the ecological environment of mining areas. Exploring vegetation

Linking vegetation indexes from remote sensing and long-term prospection data to help in the preventative control of desert locust : O401M19 IPM [PDF]

open access: yes, 2012
Desert Locust management is nowadays done through a preventative control strategy that consists in avoiding populations to reach high densities and a gregarization process leading to uncontrollable swarms.

Development and Optimization of the Ratio Vegetation Index on the Visible and Infrared Spectrum [PDF]

open access: yes, 2018
This study aims to find a suitable vegetation index model to analyze the distribution of clove vegetation in Buleleng regency, Bali. Vegetation index model Ratio Vegetation Index (RVI) extracted from Landsat 8 was developed in the visible spectrum (l = 0.

ESTIMATING LEAF AREA INDEX OF RIVERINE VEGETATION USING HYPERSPECTRAL REMOTE SENSING AND VEGETATION INDEX

open access: yesPROCEEDINGS OF HYDRAULIC ENGINEERING, 2006
Hyperspectral data were acquired from in situ ground measurements in a riparian grass field. The leaf area index (LAI) was measured using a LAI-2000 analyzer. Data sets were analyzed by empirical approaches using simple vegetation indices (VIs), NDVI and RVI.

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

Assessing spectral similarities between rainfed and irrigated croplands in a humid environment for irrigated land mapping [PDF]

open access: yes, 2014
Deriving accurate spatial assessments of the distribution of irrigated crops has become more important in recent years for water resource planning, particularly where irrigation water resources are constrained.

Fluid and Neuroimaging Biomarkers in Microgliopathy Colony‐Stimulating Factor‐1 Receptor‐Related Disorders

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aims to identify both fluid and neuroimaging biomarkers for CSF1R‐RD that can inform the optimal timing of treatment administration to maximize therapeutic benefit, while also providing sensitive quantitative measurements to monitor disease progression.
