Integrated Transcriptomics Reveals Evolutionary Trajectories and Cell Density‐Dependent Mechanisms in Aldosterone‐Producing Adenomas

open access: yesAdvanced Science, EarlyView.
Aldosterone‐producing adenomas (APAs) develop via two distinct paths: directly from adrenal zona glomerulosa (zG) cells, or stepwise from zG cells through aldosterone‐producing micronodules (APMs) before progressing to APAs. Advanced single‐cell and spatial analyses identified distinct cell states linked to oxidative stress and cell–cell interactions ...

A Novel Function of Nonadecanoic Acid in Regulating Glucose Homeostasis

open access: yesAdvanced Science, EarlyView.
This study identifies the odd‐chain fatty acid C19:0 as an endogenous ligand of GPR120 that promotes glucose homeostasis via Gαq signaling. In obesity, elevated palmitic acid suppresses endogenous C19:0 production through a miRNA–PPARα–HACL1 pathway, offering a promising direction for understanding the role of OCFAs in human health.

On the Fairness of Internet Congestion Control over WiFi with Deep Reinforcement Learning

open access: yesFuture Internet
For over forty years, TCP has been the main protocol for transporting data on the Internet. To improve congestion control algorithms (CCAs), delay bounding algorithms such as Vegas, FAST, BBR, PCC, and Copa have been developed.

Isothermal elastohydrodynamic lubrication of point contacts. 4: Starvation results [PDF]

open access: yes
The influence of lubricant starvation on minimum film thickness was investigated by moving the inlet boundary closer to the contact center. The following expression was derived for the dimensionless inlet distance at the boundary between the fully ...

Strategy of Nannochloropsis Against Environment Starvation: Population Density and Crude Lipid Contents [PDF]

open access: yes, 2013
Nannochloropsis sp., an unicellular marine microalgae, has potential function as a food source for fish larvae and in chemical industry. Microenvironmental conditions, especially nitrogen and salinity stress in marine ecosystems, became major factor ...

XIAP Stabilizes DDRGK1 to Promote ER‐Phagy and Protects Against Noise‐Induced Hearing Loss

open access: yesAdvanced Science, EarlyView.
Mechanism of GAS‐mediated protection against noise‐induced hearing loss (NIHL). Noise exposure activates the ATF4/eIF2α axis, downregulating XIAP and promoting DDRGK1 degradation, thereby inhibiting ER‐phagy and leading to hair cell (HC) death. GAS treatment rescues XIAP and DDRGK1 expression, reactivating ER‐phagy to mitigate HC loss, synaptic damage,

Bioabsorbable Endovascular Adhesive Tape (BEAT) for Improving Vascular Regeneration

open access: yesAdvanced Science, EarlyView.
A bioabsorbable endovascular adhesive tape (BEAT) platform based on a hierarchical polyelectrolyte complex is developed to enhance drug delivery in the DCB system. The coating enables rapid transfer to the vessel, provides short‐term mechanical support, and promotes both immediate transfer and long‐term retention of drugs at the lesion site.

The role of low levels of juvenile hormone Esterase in the metamorphosis of Manduca sexta

open access: yesJournal of Insect Science, 2001
The activity of juvenile hormone esterase (JHE) in feeding fifth instar larvae of Manduca sexta increases gradually with larval weight and rises to a peak after larvae pass the critical weight when juvenile hormone secretion ceases.

Selective Targeting of Tip Endothelial Cells as a Therapeutic Strategy for Tumor Angiogenesis

open access: yesAdvanced Science, EarlyView.
Doppel protein is selectively expressed in tip endothelial cells within the tumor vasculature, where it promotes tip cell motility and stabilizes the tip cell phenotype. Targeting Doppel with monoclonal antibodies disrupts this stabilization, impairs angiogenic sprouting, and reduces tumor angiogenesis, offering a selective and druggable switch for ...
