Risk Prediction of Three Different Subtypes of Highly Pathogenic Avian Influenza Outbreaks in Poultry Farms: Based on Spatial Characteristics of Infected Premises in South Korea

Frontiers in Veterinary Science, 2022
From 2003 to 2017, highly pathogenic avian influenza (HPAI) epidemics, particularly H5N1, H5N8, and H5N6 infections in poultry farms, increased in South Korea.

Seasonality and spatial variability of dynamic precipitation controls on the Tibetan Plateau [PDF]

Earth System Dynamics, 2016
Abstract. The Tibetan Plateau (TP) is the origin of many large Asian rivers, which provide moisture for large regions in South and East Asia. Therefore, the water cycle on the TP and adjacent high mountain ranges and especially the precipitation distribution plays an important role for the water availability for billions of people in the regions ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Spatial variability and directional shifts in postural control in Parkinson’s disease

Clinical Parkinsonism & Related Disorders
Individuals with Parkinson's disease exhibit tremors, rigidity, and bradykinesia, disrupting normal movement variability and resulting in postural instability. This comprehensive study aimed to investigate the link between the temporal structure of postural sway variability and Parkinsonism by analyzing multiple datasets from young and older adults ...

Vegetation and Topographic Control on Spatial Variability of Soil Organic Carbon

Pedosphere, 2013
Abstract Soil organic carbon (SOC) is one of the most important parameters affecting the hydraulic characteristics of natural soils. Despite being rather easy to measure, SOC is known to be highly variable in space. In this study, vegetation, climate, and morphology factors were used to reproduce the spatial distribution of SOC in the mineral ...

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

FEBS 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.

Spatial scale effects in environmental risk-factor modelling for diseases

Geospatial Health, 2013
Studies attempting to identify environmental risk factors for diseases can be seen to extract candidate variables from remotely sensed datasets, using a single buffer-zone surrounding locations from where disease status are recorded. A retrospective case-

Spatial and temporal variability in cyanobacterial populations controlled by physical processes [PDF]

Journal of Plankton Research, 2004
The Fitzroy impoundment is a long slender water body (10 m deep) formed by the regulation of the Fitzroy River in tropical Australia. Large, monsoonally driven discharges in late summer flush the impoundment repeatedly leaving, after 2 months, a longitudinally uniform, well-mixed water column, rich in dissolved nutrients and with high turbidity.
