: Elastic compression stockings are used to prevent venous thrombosis in postsurgical patients. However, they have been associated with skin complications, such as medical device-related pressure ulcers. This study aimed to assess the effect of elastic compression stockings on the skin tissue status of the lower limbs. : Transcutaneous oxygen pressure (TcPO) was measured in the anterior tibia and corresponding soft skin of healthy subjects before, during, and after continuous use of elastic stockings for 30 min. : Wearing elastic stockings significantly reduced TcPO in the skin of the anterior tibia, and removal of the stockings restored TcPO values. Both individuals who exercised regularly and men had lower TcPO at all measurement points than both individuals who did not exercise and women. Older subjects (50-60 years) had reduced TcPO in the sural region than younger ones (20-30 years). : The use of elastic compression stockings caused an early decrease of TcPO in healthy subjects. Clinical patients were predicted to be at a high risk of wounding.

The development of a direct compression excipient with extended-release property is crucial for improving tablet manufacturing and drug delivery. This research focuses on developing a novel co-processed excipient composed of rice starch (RS), methylcellulose (MC), and colloidal silicon dioxide (CSD) using a wet granulation technique. The ratios of RS: MC (1.

In this research, poly(lactic acid) (PLA) nanocomposites with multi-walled carbon nanotubes (MWCNT) were produced by extrusion, injection, and compression molding, focusing on electromagnetic shielding. Various amounts of carbon nanotubes (MWCNTs) were tested in PLA matrix, specifically ranging from 1 to 4 parts per hundred resin (phr). The resulting nanocomposites were analyzed before and after undergoing annealing heat treatment.

This article systematically investigated the improvement effect of polypropylene fiber (PPF) on the mechanical and freeze-thaw properties of alkali-activated fly ash slag concrete (AAFSC) with high fly ash content and cured at room temperature. Fly ash and slag were used as precursors, with fly ash accounting for 80% of the total mass. A mixed solution of sodium hydroxide and sodium silicate was used as alkali activator, and short-cut PPF was added to improve the performance of AAFSC.

Almond shells (ASs) are a potential source of cellulose that could be obtained through sustainable methods for their valorisation. Biocomposites (BCs) from polyvinyl alcohol (PVA) and cellulose are interesting materials for developing sustainable packaging materials. BC based on PVA and AS cellulose were obtained by melt blending and compression moulding, by using subcritical water extraction at 160 or 180 °C, and subsequent bleaching with sodium chlorite (C) or hydrogen peroxide (P) to purify cellulose.

Triply periodic minimal surfaces (TPMSs) are known for their smooth, fully interconnected, and naturally porous characteristics, offering a superior alternative to traditional porous structures. These structures often suffer from stress concentration and a lack of adjustability. Using laser powder bed fusion (LPBF), we have fabricated Inconel 625 sheet-based TPMS lattice structures with four distinct topologies: Primitive, IWP, Diamond, and Gyroid.
