Optimized synthesis of biphasic calcium phosphate: enhancing bone regeneration with a tailored β-tricalcium phosphate/hydroxyapatite ratio.

Biphasic calcium phosphate (BCP) is a bioceramic widely used in hard tissue engineering for bone replacement. BCP consists of β-tricalcium phosphate (β-TCP) - a highly soluble and resorbable phase - and hydroxyapatite (HA) - a highly stable phase, creating a balance between solubility and resorption, optimally supporting cell interactions and tissue growth. The β-TCP/HA ratio significantly affects the resorption, solubility, and cellular response, with a higher β-TCP ratio increasing resorption due to its solubility.

Accelerating the Discovery of Abiotic Vesicles with AI-Guided Automated Experimentation.

The first protocells are speculated to have arisen from the self-assembly of simple abiotic carboxylic acids, alcohols, and other amphiphiles into vesicles. To study the complex process of vesicle formation, we combined laboratory automation with AI-guided experimentation to accelerate the discovery of specific compositions and underlying principles governing vesicle formation. Using a low-cost commercial liquid handling robot, we automated experimental procedures, enabling high-throughput testing of various reaction conditions for mixtures of seven (7) amphiphiles.

Poorer objective but not subjective driving performance in drivers vulnerable to sleep loss effects during extended wake.

Sleepiness-related errors are a leading cause of driving accidents, requiring drivers to effectively monitor sleepiness levels. However, there are inter-individual differences in driving performance after sleep loss, with some showing poor driving performance while others show minimal impairment. This research explored if there are differences in self-reported sleepiness and driving performance in healthy drivers who exhibited vulnerability or resistance to objective driving impairment following extended wakefulness.

Apolipoprotein-L1 G1 variant contributes to hydrocephalus but not to atherosclerosis in apolipoprotein-E knock-out mice.

Introduction: In USA, six million individuals with Sub-Saharan ancestry carry two high-risk variants, which increase the risk for kidney diseases. Whether APOL1 high-risk variants are independent risk factors for cardiovascular diseases is unclear and requires further investigation.

Methods: We characterized a mouse model to investigate the role of APOL1 in dyslipidemia and cardiovascular diseases.

Exploring cigarette butts pollution in Vung Tau beaches: A case study in Vietnam.

Cigarette butts (CBs), alongside other plastic items, are widely recognized as a significant source of marine litter in coastal areas worldwide. This research is the first to examine CB pollution, offering valuable insights into its impact across various beaches in Vung Tau, Vietnam. A total of 512 CBs were collected, with an average density of 0.
