Recent Trends in the Recurrence of North Atlantic Atmospheric Circulation Patterns

open access: yesComplexity, 2018
A few types of extreme climate events in the North Atlantic region, such as heatwaves, cold spells, or high cumulated precipitation, are connected to the recurrence of atmospheric circulation patterns.

Atmospheric teleconnection mechanisms of extratropical North Atlantic SST influence on Sahel rainfall [PDF]

open access: yes, 2014
Extratropical North Atlantic cooling has been tied to droughts over the Sahel in both paleoclimate observations and modeling studies. This study, which uses an atmospheric general circulation model (GCM) coupled to a slab ocean model that simulates this ...

The Importance of Isentropic Mixing in the Formation of the Martian Polar Layered Deposits

open access: yesThe Planetary Science Journal, 2023
Layers of ice and dust at the poles of Mars reflect variations in orbital parameters and atmospheric processes throughout the planet's history and may provide a key to understanding Mars's climate record.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Inter-basin contrast in the Southern Ocean warming

open access: yesNature Communications
The Southern Ocean (SO) is a major contributor to global ocean heat uptake, exhibiting deep-reaching warming trends within the 35°S-55°S band. Here, we reveal a notable inter-basin contrast in the SO warming rates.

Projections of thermal conditions for Poland for winters 2021?2050 in relation to atmospheric circulation

open access: yesMeteorologische Zeitschrift, 2013
Winter thermal conditions in Poland are largely determined by atmospheric circulation. Therefore, the projection of future temperature change should be considered in relation to changes in circulation patterns. This paper assesses the spatial variability

Two-Way Feedback Interaction between the Thermohaline and Wind-Driven Circulations [PDF]

open access: yes, 2006
The thermohaline circulation (THC) affects the meridional atmospheric temperature gradient and therefore the atmospheric wind and the wind-driven ocean circulation.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...
