Determination of Reservoir Ecosystem Status in Cimahi City Govenrment Office

open access: yesJurnal Presipitasi
Cimahi City continues to try to repair the damaged reservoir to function optimally as a raw water reservoir. This effort requires identifying the status of the reservoir ecosystem by assessing three standard criteria: aquatic, boundary, and terrestrial ...

Assessing the trophic status of Lake Mikri Prespa, Greece [PDF]

open access: yesAnnales de Limnologie, 1989
Lake Mikri Prespa is a shallow water basin characterized by unstable thermal stratification, primary dimictic condi­ tions and clinograde distribution of dissolved oxygen. The nutrient concentrations are high, indicating a trend towards eutrophication. Total phosphorus input calculated on the basis of the export coefficient accounting for land-uses and

HRS Degradation‐Induced Nicotinamide Deficiency in Placental Extracellular Vesicles Triggers Preeclampsia by Disrupting Maternal‐Fetal Immune Homeostasis

open access: yesAdvanced Science, EarlyView.
This study shows that lower NAM levels in PE‐derived pEVs correlate with disease severity. NAM‐deficient pEVs reduce Th1 and Th17 inhibition, leading to PE‐like symptoms. NAM in pEVs inhibits Th1 via SIRT1 and Th17 via macrophages. Reduced NAM in PE‐EVs is due to decreased HRS expression in trophoblasts, resulting from elevated HSP27.

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

Reductions in the dietary niche of southern sea otters (Enhydra lutris nereis) from the Holocene to the Anthropocene. [PDF]

open access: yes, 2020
The sea otter (Enhydra lutris) is a marine mammal hunted to near extinction during the 1800s. Despite their well-known modern importance as a keystone species, we know little about historical sea otter ecology.

Hepatocyte Mettl3 Deficiency Drives Primary Sclerosing Cholangitis and Liver Fibrosis via Cholangiocyte‐Macrophage Crosstalk

open access: yesAdvanced Science, EarlyView.
Schematic illustration demonstrating that hepatic Mettl3 depletion significantly elevates the secretion of Mif and Csf1. This elevation facilitates Trem2+ macrophage infiltration and triggers cholangiocyte remodeling through the Spp1‐Cd44 interaction, resulting in spontaneous PSC development in vivo.
