3D In Vitro Models of Breast Cancer: Current Challenges and Future Prospects Toward Recapitulating the Microenvironment and Mimicking Key Processes

open access: yesAdvanced Biology, EarlyView.
In vitro cancer models are advantageous for studying important processes such as tumorigenesis, cancer growth, invasion, and metastasis. The complexity and biological relevance increase depending on the model structure, organization, and composition of materials and cells.

Water Pollution

open access: yes, 2022
Water pollution is the contamination of water, Likes rivers, Lakes, Etc. Usually, as a result of human activities, it negatively affects its legitimate uses. Water is the great blessing of Allah; no one can withstand without water. Everybody needs water for their survival of life. It is estimated that 70% of humans rely on water.

Pollution lumineuse, pollution insidieuse

open access: yesBulletin de l'Académie Nationale de Médecine, 2020
RESUME Contrairement aux autres sources de pollution, l’agression lumineuse par les nouvelles sources de lumiere artificielle sont moins souvent denoncees. Et cependant, la retine y est constamment exposee. A tout le moins une photo-protection par des verres filtrant les rayonnements nocifs pour la retine pourrait etre a recommander, tout ...

Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

open access: yesAdvanced Engineering Materials, EarlyView.
High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Laboratory‐Scale Procedure for Evaluating the Flux Efficiency on Melt Cleanliness and Tensile Properties of Recycled Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
A laboratory‐scale procedure is developed to evaluate the efficiency of melt‐cleaning and drossing fluxes during aluminium alloy recycling, studying their effects on melt cleanliness and tensile properties of secondary foundry alloys. This work provides a practical tool for foundries and aluminium refiners to assess the efficiency of salt fluxes in ...

Air pollution and COVID-19 mortality in the United States: Strengths and limitations of an ecological regression analysis

open access: yesScience Advances, 2020
We describe the challenges and opportunities of analyzing links between exposure to air pollution and vulnerability to COVID-19. Assessing whether long-term exposure to air pollution increases the severity of COVID-19 health outcomes, including death, is
