Active Learning‐Driven Discovery of Sub‐2 Nm High‐Entropy Nanocatalysts for Alkaline Water Splitting

Advanced Functional Materials, EarlyView.
High‐entropy nanoparticles (HENPs) hold great promise for electrocatalysis, yet optimizing their compositions remains challenging. This study employs active learning and Bayesian Optimization to accelerate the discovery of octonary HENPs for hydrogen and oxygen evolution reactions.

Optimizing Angiopep‐2 Density on Polymeric Nanoparticles for Enhanced Blood–Brain Barrier Penetration and Glioblastoma Targeting: Insights From In Vitro and In Vivo Experiments

Advanced Functional Materials, EarlyView.
The Angiopep‐2 peptide density on polymeric nanoparticles significantly impacts blood–brain barrier (BBB) penetration. This study explores this nuanced relationship using various in vitro models and in vivo assays, revealing that dynamic models better predict BBB penetration.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

The Cell Nucleus [PDF]

JAMA: The Journal of the American Medical Association, 1975
The cell nucleus is a characteristic feature of most eukaryotic cells. It is a double-membrane-bound organelle that contains the genetic information of the cell packaged in the form of chromatin.

The role of the cell nucleus in mechanotransduction

Current Opinion in Cell Biology, 2020
Mechanical forces are known to influence cellular processes with consequences at the cellular and physiological level. The cell nucleus is the largest and stiffest organelle, and it is connected to the cytoskeleton for proper cellular function.

Assembly of the cell nucleus

Trends in Genetics, 1990
Purified DNA can be assembled into structures that closely resemble cell nuclei. The cell-free systems that allow this can be exploited to study assembly pathways for several components of the nucleus. They also offer great opportunities for the experimental analysis of nuclear function.

Immunocytochemistry of the cell nucleus

Electron Microscopy Reviews, 1990
This electron microscopic review addresses in situ immunocytochemistry of the mammalian cell nucleus with special reference to the use of autoantibodies, which are the major source of antinuclear antibodies. The localization of many key nuclear antigens is documented and immunocytochemical data are related to the major functional processes of ...

Hyperthermia and the Cell Nucleus

Radiation Research, 1982
Recent reviews document that hyperthermic shock inhibits the major nuclear activities, including semiconservative DNA replication (1, 2). These inhibitions may result either from a direct effect of heat on the cell nucleus or as a consequence of changes in other cell compartments [e.g., cell membrane damage (3)].

Mechanics of the Cell Nucleus

2018
Nucleus is a specialized organelle that serves as a control tower of all the cell behavior. While traditional biochemical features of nuclear signaling have been unveiled, many of the physical aspects of nuclear system are still under question. Innovative biophysical studies have recently identified mechano-regulation pathways that turn out to be ...
