Triple coaxial microcatheter for preoperative transcatheter arterial embolization in bone and soft tissue tumors.

Background: Preoperative transcatheter arterial embolization (P-TAE) is a procedure designed to reduce intraoperative blood loss (IBL) and support the performance of surgery for bone and soft tissue tumors (BSTT).

Purpose: To develop a new P-TAE technique using a triaxial microcatheter system (TMCS) that maintains normal tissue circulation while embolizing only the feeding artery of BSTT and to investigate the safety and efficacy of P-TAE with TMCS.

Material And Methods: A total of 34 cases of BSTT in the whole body (25 men, nine women; mean age = 74.

Pseudogap in electron-doped cuprates: Strong correlation leading to band splitting.

The pseudogap phenomena have been a long-standing mystery of the cuprate high-temperature superconductors. The pseudogap in the electron-doped cuprates has been attributed to band folding due to antiferromagnetic (AFM) long-range order or short-range correlation. We performed an angle-resolved photoemission spectroscopy study of the electron-doped cuprates PrLaCeCuO showing spin-glass, disordered AFM behaviors, and superconductivity at low temperatures and, by measurements with fine momentum cuts, found that the gap opens on the unfolded Fermi surface rather than the AFM Brillouin zone boundary.

Preparation and Structural Properties of Gel Coating Films Containing Lipophilized Nanocarbon Particles Functionalized with Thixotropic Chains.

Gel coating films comprising nanodiamonds organo-modified with 12-hydroxystearic (12-OHC ) and stearic acids were prepared and characterized. Because molecules with 12-OHC groups can convert solvents into thixotropic gels, Gemini-type diamide derivatives with two 12-OHC chains were also introduced as thixotropic additives into the gel coating films. Although the 12-OHC -modified nanodiamonds did not lead to solvent gelation on their own, they displayed an affinity for the thixotropic additive molecules.

Omega-3 supplementation attenuates doxorubicin-induced cardiotoxicity but is not related to the ceramide pathway.

Cardiotoxicity is the serious side effect of doxorubicin treatment. Ceramides are formed from the degradation of sphingolipids in cell membranes and play an important role in signaling and modulating biological processes. There is evidence that omega-3 fatty acid administration can act on this pathway.

Pera orange juice ( L. ) alters lipid metabolism and attenuates oxidative stress in the heart and liver of rats treated with doxorubicin.

Background: Doxorubicin (DOX) is a highly effective chemotherapy drug widely used to treat cancer, but its use is limited due to multisystemic toxicity. Lipid metabolism is also affected by doxorubicin. Orange juice can reduce dyslipidemia in other clinical situations and has already been shown to attenuate cardiotoxicity.
