Characterization of Si3N4 powders in aqueous dispersions

Cerâmica, 1998
alpha- Si3N4 can easily oxidize when exposed in air atmosphere or other oxidizing environment. The chemistry of Si3N4 particle surfaces can change by different synthesis routes and also by subsequent processing steps.

Optimisation of Amphiphilic-Polymer Coatings for Improved Chemical Stability of NaYF4-based Upconverting Nanoparticles

Acta Chimica Slovenica, 2022
NaYF4 nanoparticles codoped with Yb3+ and Tm3+ exhibit upconversion fluorescence in near-infrared and visible spectral range. Consequently, such upconverting nanoparticles (UCNPs) can be used as contrast agents in medical diagnostics and bioassays ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

NMR studies of membrane structure and dynamics [PDF]

, 1978
Over the past decade, there has been considerable interest in the motional state of the phospholipid bilayer membrane. The motivation underlying these efforts has been the contention that the phospholipid bilayer is the basic matrix in which membrane ...

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells

FEBS Open Bio, EarlyView.
Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.

Hierarchy of Electrorheological Responses in Aqueous Smectite Clay Dispersions in Relation to DLVO Potential Barriers

Eng
This study systematically investigated the electrorheological (ER) behavior of four aqueous smectite clay dispersions—fluorinated hectorite (Ht-F), stevensite (Stv), hectorite (Ht), and saponite (Sap)—with emphasis on transparency, rheological responses,

Studies on the absorption of beta-carotene and the distribution of total carotenoid in human serum lipoproteins after oral administration*

Journal of Lipid Research, 1962
The carotenoid increment in human serum was measured after the oral administration of aqueous dispersions and lipid dispersions of β-carotene with different test meal regimens. β-carotene was readily absorbed in both forms.

Structures of Aqueous Dispersions of Phosphatidylserine

Journal of Biological Chemistry, 1973
Abstract Dilute (g10% w/v) unsonicated phosphatidylserine dispersions in H2O contain spherical particles of a wide size distribution (0.1 to 15 µm). The majority have diameters between 0.1 to 2 µm and lack the multilamellar arrangement of bilayers typical of unsonicated lecithin dispersions. Sonication produces small thermodynamically unstable vesicles

Heterogeneity of Rheumatoid Arthritis–Associated Interstitial Lung Disease by Longitudinal Forced Vital Capacity Trajectory and Associations With Disease Outcomes

Arthritis Care &Research, EarlyView.
Objective We aimed to identify unique disease trajectories within rheumatoid arthritis–associated interstitial lung disease (RA‐ILD) based on longitudinal forced vital capacity (FVC) values and their associated clinical outcomes. Methods We performed a cohort study of RA‐ILD within the Veterans Health Administration from 1999 to 2021.

Adipokines and Associations With Incident Osteoporotic Fracture in Patients With Rheumatoid Arthritis

Arthritis Care &Research, EarlyView.
Objective We assessed whether circulating adipokines are associated with incident fractures in patients with rheumatoid arthritis (RA). Methods Three adipokines (adiponectin, leptin, and fibroblast growth factor [FGF]‐21) were measured using banked enrollment serum from participants in a longitudinal RA cohort.
