This study aims to synthesize a new localized drug delivery system of bioglass, polyvinyl alcohol (PVA), cellulose (CNC), and sodium alginate (SA) beads as a carrier for methotrexate (MTX) drugs for the treatment of osteosarcoma. Methotrexate /Bioglass-loaded Polyvinyl/Cellulose/Sodium alginate biocomposite beads were prepared via the dropwise method with different concentrations of (65%SiO-30%CaO- 5%PO) bioglass. Samples were named B0, S0, S1, S2, and S3, respectively.

Ammonia nitrogen (NH-N) discharge has caused eutrophication of water bodies and harm to humans and organisms. In this work, polyvinyl alcohol (PVA), sodium carboxymethyl cellulose (CMC), diatomite (DE), and FeO were used to prepare magnetic immobilized carriers by encapsulating microorganisms for the treatment of NH-N wastewater. The response surface methodology was used to explore the optimal ratio of the immobilized carriers.

A carbon nanotube (CNT) composite is an effective method to improve the thermoelectricity of materials. However, the depletion layer between the CNT and thermoelectric (TE) material always decreases the contribution of CNT to the conductivity of the TE material. It is important to eliminate the depletion layer for improving the TE properties.

Purpose: This study aims to investigate the role and mechanism of -hydroxyl cinnamaldehyde (CMSP) in triggering ferroptosis of small cell lung cancer (SCLC) cells.
Methods: The impact of CMSP on ferroptosis in H1688 and SW1271 cells was assessed through cell experiments and biological information analysis. Moreover, the expression of heme oxygenase 1 (HMOX1) in SCLC tissue was examined.
Modeling aerobic granules in continuously flowing wastewater-treatment processes.

Continuously flowing wastewater-treatment processes can be configured for biological and physical selection to form and retain large biological aggregates (LBAs), along with suspended biomass that contains ordinary biological flocs and biomass that has detached from the LBAs. Suspended biomass and LBAs have different solids residence times (SRTs) and mass-transport resistances. Here, mathematical sub-models that describe metabolic processes, a 1-D biofilm, and spherical carriers that can migrate throughout a wastewater-treatment process were combined to simulate a full-scale demonstration train having anaerobic, anoxic, and oxic zones, as well as side-stream enhanced biological phosphorus removal.
