Article Synopsis
- Researchers are exploring liver sinusoidal endothelial cells (LSECs) and their progenitor cells (LPCs) from human pluripotent stem cells (PSCs) as potential treatments for hemophilia A, a condition caused by insufficient coagulation factor VIII (FVIII) production.* -
- The study aimed to enhance the process of mesoderm differentiation to efficiently produce LSEC-like cells from human induced pluripotent stem cells (iPSCs), observing a successful differentiation rate of approximately 65% for LPCs and 54% for LSEC-like cells.* -
- Optimizing specific factors like CHIR99021 and bone morphogenetic protein 4 led to significant FVIII protein secretion from L
Article Synopsis
- The study focused on the structural and superconducting properties of the Bi-based superconductor BiRh(SeS) under varying pressure conditions.
- BiRhSe shows superconductivity with a transition temperature below 1.0 K and a charge density wave transition at 240 K, whereas BiRhS does not exhibit superconductivity but has a structural transition at 165 K.
- Researchers created samples of BiRh(SeS) and examined how its superconducting properties and phase transitions change with different ratios of Se to S, aiming to understand the relationship between these materials and their phase behavior under pressure.
Article Synopsis
- CD34-positive endothelial progenitor cells (EPCs) are important for promoting blood vessel growth and could be useful in treating ischemic diseases, but their numbers and quality decline due to various factors, prompting research into better generation methods.* -
- Researchers explored using chemical compounds, specifically PD0325901, a MEK inhibitor, to reprogram human umbilical vein endothelial cells (HUVECs) into CD34-positive cells, leading to a significant increase in CD34 expression.* -
- The findings indicate that PD0325901 primarily enhances CD34 expression by reducing ERK phosphorylation in endothelial cells, offering insights for improving regenerative therapies for blood flow-related conditions.*
Dynamical fluctuations of the elastic strain in strongly correlated systems are known to affect the onset of metal-to-insulator or superconducting transitions. Here we report their effect on the properties of a family of bandwidth-controlled alkali-intercalated fullerene superconductors. We introduce elastic strain through static local structural disorder in a systematic and controllable way in the fcc-structured K Cs C (with potassium content, 0.

The formation of a trimer of Te atoms at low temperatures has been fully explored using these methods. An increase in the Te-Fe distance at approximately 150 K was suggested by EXAFS and presumably indicates the formation of a Te trimer.
