Dynamic Modulation of the Microenvironment Promotes Functional Maturation of Engineered Tissues

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered tissues lack the dynamic microenvironment of native tissues. A biocompatible, diffusible small molecule to dynamically modulate tissue microenvironments during maturation is used. Timing‐dependent modulation yields distinct outcomes, producing thicker, more native‐like blood vessels, stronger and more mature cardiac tissues, and optimized ...

Taming the Immiscibility of Gold, Iron, and Boron to Craft Chemodegradable Nanoparticles for Multimodal Imaging and Radiotherapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Over half of cancer patients undergo radiotherapy. Laser ablation enabled the synthesis of immiscible Au‐Fe‐B nanoparticles designed as degradable bimodal radiosensitizers for X‐ray radiotherapy (XRT), boron neutron capture therapy (BNCT), and bimodal imaging for X‐ray computed tomography (CT) and magnetic resonance imaging (MRI). These nanosensitizers

The heavy-element abundances of AGB stars and the angular momentum conservation model of wind accretion for barium stars [PDF]

open access: yes, 2000
Adpoting new s-process nucleosynthesis scenario and branch s-process path, we calculate the heavy-element abundances and C/O ratio of solar metallicity 3M_sun TP-AGB stars.

Bioengineered 3D hPSC‐Cholangiocyte Ducts With Physiological Signals for Biliary Disease Modeling

open access: yesAdvanced Healthcare Materials, EarlyView.
Tian and colleagues generated a bioengineered bile duct from human pluripotent stem cell (hPSC)‐derived intrahepatic cholangiocytes within a high‐throughput, 384‐well platform to systematically examine the influence of biliary physiological signals including fluid flow, stromal cells and bile acids, and models intrahepatic biliary disease progression ...

Barium‐Catalyzed Dehydrocoupling of Terminal Alkynes and Hydrosilanes

open access: yesChemistryEurope
The dehydrocoupling of terminal alkynes and hydrosilanes catalyzed by alkaline‐earth complexes: calcium, strontium and, most prominently, barium, is reported.

Barium and psoriasis: a mini-review and hypothesis linking environmental exposures to ion channel modulation

open access: yesFrontiers in Medicine
Psoriasis is a complex autoimmune skin disorder with rising prevalence and significant comorbidities. Although its etiology remains multifactorial, recent epidemiologic and mechanistic studies—including the NHANES-based analysis by Chen et al.—suggest ...
