Novel mixture of mRNA in nanoparticles show therapeutic potential against tumor progression

9 декабря, 2024 - 20:51
Therapeutic mRNAs offer great potential as a versatile and precise tool against cancer and other diseases. However, the therapeutic effectiveness is limited by the poor translation uptake of naked mRNA. To circumvent this challenge, researchers from VIB, VUB, Ghent University, and eTheRNA Immunotherapies developed an immunotherapeutic platform based on lipid-based nanoparticles (LNPs).

Nanoparticle-mediated gene therapy fixes major cause of stillbirth and premature birth in guinea pig model

6 декабря, 2024 - 00:32
The life of billions of people inhabiting Earth is owed to a temporary organ that supported and nourished them in a mother's womb. The placenta, or afterbirth, is considered sacred by some cultures, its pivotal role in pregnancy recognized as far back as the raising of Egypt's pyramids. It provides nutrients and oxygen to the fetus via the umbilical cord, acting like a gut, kidney, liver, and lungs.

Experiments show coating rice seedling with nanoscale carbon dots from durian helps rice plants thrive in salty soil

5 декабря, 2024 - 21:32
Extreme weather and pollution have increased the salt content in some soil, making growing conditions harsh for salt-sensitive crops like rice. Now, researchers reporting in ACS Nano detail a possible solution that doesn't require genetic modification to make rice plants thrive in these conditions. In lab experiments, they determined that coating rice seedlings with magnesium-doped carbon dots—derived from durian peels—increased the seedlings' antioxidant activity and photosynthesis, reducing the stress caused by salty soil.

Thin coating of MXene material could replace thick layers of insulation

5 декабря, 2024 - 19:37
Materials that conduct electricity well, like metals, also tend to conduct heat. For instance, a metal spoon left in a hot cup of tea will get hot, while the ceramic mug remains cool. This is because good electrical conductors are usually good heat conductors too.
