Pickering emulgels stabilized by graphene oxide (GO) with didodecyldimethylammonium bromide (DDAB) as an auxiliary surfactant and liquid paraffin as the oil phase have proved to be an excellent 3D printable ink. This paper elucidates the structure of such emulgels by a combination of microscopy before and after intensive shear as well as broadband dielectric spectroscopy and rheology in the linear and nonlinear regime. An increase of the DDAB surfactant and GO-contents leads to a systematic increase of modulus and viscosity, a reduction of the limits of the nonlinear regime and a more complicated variation of the normal forces, with negative normal forces at high shear rate for low GO-contents and positive normal forces at high GO-contents.

- The study explores how flexible polymer chains at the interface of cellulose nanofiber (CNF)-based Pickering emulsions affect their rheological and dielectric properties, using liquid paraffin and didodecyldimethylammonium bromide (DDAB) as components.
- Results show that varying the amounts of CNF and DDAB alters droplet size and dispersion, leading to changes in viscosity and yield points, with CNF promoting a network formation and DDAB assisting in solubilizing CNF.
- Polarized optical microscopy and fluorescence analysis reveal distinct behaviors of droplets based on CNF and DDAB content, while broadband dielectric spectroscopy further clarifies the relationship between composition, morphology, and physical interactions within the emulsion system
Few studies have examined the association between perioperative blood transfusion and postoperative delirium (POD) in aged patients undergoing total hip replacement surgery. In this prospective study, 186 patients older than 65 years undergoing elective unilateral total hip replacement surgery were enrolled. Of those, 94 patients were randomly assigned to the restrictive strategy transfusion strategy group, in which red blood cells were transfused in order to maintain 10.

Article Synopsis
- - The study investigates a surgical technique using an island flap to treat skin defects on the distal phalanges of fingers, specifically from the 2nd to 5th fingers.
- - Over a period of five years, 54 patients with 61 affected fingers underwent this procedure, with outcomes showing complete survival of all flaps and good recovery in terms of texture, color match, and sensation.
- - The island flap method was found to be effective and resulted in normal movement of the finger joints, making it a recommended approach for dealing with these types of injuries.
Background: The cannabinoid receptor-2 (CB2) is important for bone remodeling. In this study, we investigated the effects of CB2 selective antagonist (AM630) on receptor activator of nuclear factor kappa B (RANK) ligand (RANKL) induced osteoclast differentiation and the underlying signaling pathway using a monocyte-macrophage cell line-RAW264.7.

We analyzed the difference of arteriolar pathology between CAA patients (CAAs) and vascular dementia patients without CAA (VaDs).
Methods: Ten deceased CAAs and twelve deceased VaDs were available for this study.
Article Synopsis
- The study aimed to evaluate the therapeutic effects of treating collapsed and comminuted distal radius fractures in 26 hospitalized patients from 1998 to 2003.
- The treatment involved open reduction, sustained bone grafting, and the use of a joint external fixator, which helped restore the anatomical shape of the radius.
- Results indicated successful fracture healing with no length discrepancies, intact joint surfaces, and a majority rated as excellent or good based on the Dieust criterion.
