Sustained astrocytic clusterin expression improves remodeling after brain ischemia

open access: yesNeurobiology of Disease, 2006
Clusterin is a glycoprotein highly expressed in response to tissue injury. Using clusterin-deficient (Clu−/−) mice, we investigated the role of clusterin after permanent middle cerebral artery occlusion (MCAO).

Age and gravitational separation of the stratospheric air over Indonesia [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
The gravitational separation of major atmospheric components, in addition to the age of air, would provide additional useful information about stratospheric circulation.

Temporal bone pneumatization: A scoping review on the growth and size of mastoid air cell system with age.

open access: yesPLoS ONE, 2022
The interest in the mastoid air cell system arose from the association between temporal bone aeration and otitis media. Its size and growth have been considered when planning chronic and middle ear surgeries.

Assessment of a Portable Air Cleaning Device Performance in Eliminating Indoor Air Contaminants by Considering Particle Transport Characteristics

open access: yesApplied Sciences
Human health is significantly impacted by the quality of the air in living areas. Numerous factors, such as the kind of particle, clean air delivery rate, room geometry, surface features, and thermal plume produced by people or other equipment, all have ...

Seasonal and inter-annual variability of lower stratospheric age of air spectra [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Trace gas transport in the lower stratosphere is investigated by analysing seasonal and inter-annual variations of the age of air spectrum – the probability distribution of stratospheric transit times.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Age of air from ACE-FTS measurements of sulfur hexafluoride [PDF]

open access: yesAtmospheric Chemistry and Physics
Climate models predict that the Brewer–Dobson circulation (BDC) will accelerate due to tropospheric warming, leading to a redistribution of trace gases and, consequently, to a change of the radiative properties of the atmosphere.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

The effects of mixing on age of air [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2014
Mean age of air (AoA) measures the mean transit time of air parcels along the Brewer-Dobson circulation (BDC) starting from their entry into the stratosphere. AoA is determined both by transport along the residual circulation and by two-way mass exchange (mixing).
