Article Synopsis
  • Percutaneous mechanical thrombectomy (PMT) is an effective method for treating iliofemoral deep vein thrombosis (DVT) by dissolving and removing clots, especially when anticoagulation alone isn't sufficient.
  • However, the use of devices like AngioJet can lead to complications such as intravascular hemolysis and hemoglobinuria, increasing the risk of acute kidney injury (AKI).
  • Clinicians must be vigilant about these potential risks, provide clear information to patients about the possibility of AKI, and ensure timely referrals to nephrologists if severe kidney issues arise.

Article Synopsis
  • - Arterial stiffening contributes significantly to age-related cardiovascular diseases through processes like proinflammation, collagen deposition, and calcification, primarily driven by the TGF-β1 signaling pathway.
  • - The protein vasorin (VASN) helps regulate TGF-β1's proinflammatory effects, but its levels decrease with age due to activation of the enzyme MMP-2, worsening arterial fibrosis and calcification.
  • - Understanding the interaction between VASN and TGF-β1 could lead to new treatments focused on reducing age-related cardiovascular issues by preventing harmful remodeling in arterial walls.

This research investigates the efficacy of zinc oxide (ZnO) tubes in decontaminating polluted water using a substrate-free hydrothermal synthesis process for ZnO tubes. The synthesized tubes are impregnated into calcium alginate microfibres, strategically chosen for their high surface area to enhance photocatalytic degradation performance and for practical handling during decontamination and subsequent collection, thereby preventing secondary contamination. Structural and morphological analyses, conducted using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD), thoroughly characterize the properties of the ZnO tubes and the composite material.

Dry reforming of methane (DRM) has recently received wide attention owing to its outstanding performance in the reduction and conversion of CH and CO to syngas (H and CO). From an industrial perspective, nickel (Ni)-supported catalysts have been deemed among the most suitable catalysts for DRM owing to their low cost and high activity compared to noble metals. However, a downside of nickel catalysts is their high susceptibility to deactivation due to coke formation and sintering at high temperatures.
