Osaka Metropolitan University researchers confirm using zebrafish that if a certain gene is not excluded when vertebrate embryos are developing, the notochord will not elongate properly, resulting in a shortened form.
Typically, closely related animal species have difficulty coexisting because they are competing for similar resources. Despite eating the same figs, binturong, small-toothed palm, masked palm, and common palm civets do coexist together. To understand how they coexist, a new study explores their degree of faunivory.
The study examines how masseter muscle volume (MMV) affects sarcopenia risk in older adults, revealing that reduced MMV is linked to a higher sarcopenia risk independent of nutritional intake, particularly in men. Additionally, comparisons between the characteristics of the masseter muscle and appendicular skeletal muscle provided new insights into the functional and genetic factors influencing MMV. These findings hold promise as an innovative approach for the prevention and early diagnosis of sarcopenia.
The skin microbiome plays a key role in skin health and disease. While imbalances in skin microbiome composition are linked to disease, studying it has been challenging due to limited methods for culturing multiple bacterial species together. Now, scientists have developed a new medium, the "TUS Skin Bacteria Co-culture (TSBC)," which allows co-culturing of key skin bacteria while preserving their natural balance, opening new pathways for studying microbial interactions and skin health.
As we age, our muscles atrophy. Earlier this year, researchers at Kyushu University found that hepatocyte growth factor (HGF), a protein critical in skeletal muscle development loses its functionality due to nitration as we age. Now, the same team has developed a monoclonal antibody that blocks the nitration sites of HGF, effectively preventing the protein’s age induced loss of function. Their findings were validated utilizing rat muscles cell culture.
Researchers at Kyushu University have developed a new bio-inspired approach to building complex 3D microfluidic networks by utilizing plant roots and fungal hyphae as molds. The team grew plants and fungi in nanoparticles of silica, then baked out the plants and solidified the glass. What remains is glass with micrometer-sized networks where the roots used to be.
