Dynamics of a salinity-prone agricultural catchment driven by markets, farmers' attitude and climate change [PDF]

open access: yes, 2007
An agent-based simulation model has been developed with CORMAS combining simplified bio-physical processes of land cover, dry-land salinity changes, rainfall, farm profitability and farmer decisions on land uses in a dry-land agricultural catchment (no ...

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

open access: yesAdvanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Tendon Organoids Enable Functional Tendon Rejuvenation Through ALKBH5‐Dependent RNA Demethylation

open access: yesAdvanced Science, EarlyView.
FT organoids reverse the aged phenotype of tendon cells, reinstating a fetal‐like state. This breakthrough establishes a potent cell source for tendon tissue engineering, effectively advancing regenerative medicine. ABSTRACT Adult tendon injuries pose a major clinical challenge due to limited self‐repair capacity, resulting in suboptimal regeneration ...

Valuation of livestock population and national feed security to enhance livestock productivity in Ethiopia

open access: yesVeterinary Medicine and Science
Background Feed is a major input in the livestock industry and covers about 60%–70% of the total cost of producing meat, milk and eggs. Inadequate feed supply in terms of quality and quantity leads to lower production performance in livestock.
