Objective: The combination of endovenous therapies with stab avulsion or ultrasound guided foam sclerotherapy is widely performed. However, these conventional techniques tend to result in incomplete avulsions or persistent varicosities.
Methods: One hundred and thirteen legs in 97 consecutive patients who underwent 1470 nm laser ablation for great saphenous varicose veins were enrolled.
We established a methodology for initiating cross-linking of antibodies selectively on the cell surface through intermolecular copper-free click reactions facilitated by increased effective concentrations of antibodies binding to target antigens. Upon cross-linking of tetrazine- and bicyclononyne-modified trastuzumab on the surface of HER2-overexpressing cells, increased antibody uptake and activation of intracellular signaling were observed. Our findings demonstrate that the cross-linking reaction can significantly alter the biophysical properties of proteins, activating their unique functionalities on targeted cells to realize an increased cargo delivery and synthetic manipulation of cellular signaling.

A 39-year-old man complained of right lower leg skin pigmentation, pain and fatigue for several years. Duplex ultrasound revealed that the great saphenous vein diameter at the saphenofemoral junction level was 7.

Purpose: To improve the evaluation of low-attenuation plaque (LAP) by using semiautomated software and to assess whether the use of a proposed automated function (LAP editor) that excludes voxels adjacent to the outer vessel wall improves the relationship between LAP and the presence and size of the lipid-rich component (LRC) verified at intravascular US. At coronary CT angiography, quantification of LAP can improve risk stratification. defined as the area between the vessel and the lumen wall, is prone to partial volume effects from the surrounding pericoronary adipose tissue.
