Temperature programed desorption of water ice from the surface of amorphous carbon and silicate grains as related to planet-forming disks

open access: yes, 2018
Understanding the history and evolution of small bodies, such as dust grains and comets, in planet-forming disks is very important to reveal the architectural laws responsible for the creation of planetary systems.

Suppression of lung adenocarcinoma migration through organelle alkalization by human lactoferrin – albumin fusion

open access: yesFEBS Open Bio, EarlyView.
This paper reveals how human lactoferrin–albumin fusion (hLF‐HSA) potently suppresses lung adenocarcinoma cell migration. hLF‐HSA upregulates NHE7, leading to Golgi alkalization, disruption of the Golgi secretome, downregulation of MMP1, and reversal of EMT. These findings suggest a novel Golgi‐targeting strategy to suppress cancer cell migration.

The effect of a non-volatile dust mantle on the energy balance of cometary surface layers [PDF]

open access: yes
It is likely that large parts of a cometary surface layer consist of porous ices, which are covered by a thin layer of non-volatile debris, whose structure is also fluffy and porous. In this paper the results of model calculations are presented.

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment

open access: yesAging and Cancer, EarlyView.
Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Structural properties of impact ices accreted on aircraft structures [PDF]

open access: yes
The structural properties of ice accretions formed on aircraft surfaces are studied. The overall objectives are to measure basic structural properties of impact ices and to develop finite element analytical procedures for use in the design of all deicing

Inhibition of Classical and Alternative Complement Pathway by Ravulizumab and Eculizumab

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore the feasibility of classical (CH50) and alternative (AH50) complement pathway activity as potential biomarkers for treatment guidance and monitoring during therapy with ravulizumab in patients with generalized myasthenia gravis (gMG) and compare these to therapeutic drug monitoring under eculizumab.

Holistic Mapping of the Present-day Martian Seasonal CO2 Frost. I. Frost Detection within Global Visible, Thermal, and Spectral Data Sets

open access: yesThe Planetary Science Journal
A dominant driver of Martian atmospheric, landscape, and landform activity is the annual cycle of CO _2 and water, seasonally moving between atmospheric gases and surface frost.
