EFFORTS TO OPTIMIZE THE OPERATION OF THE DADAHUP LOWLAND IRRIGATION AREA IN CENTRAL KALIMANTAN

Jurnal Teknik Hidraulik, 2023
Dadahup lowland irrigation area is one of the areas developed as a food estate. Land cover change to shrubs is caused by channels with buildings that are not functioning optimally, so it is often hit by floods and droughts.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...
