Successful recanalization of previously subintimal stenting of the right coronary artery

Stent placement in the subintimal or false lumen is a rare complication of coronary interventions. Subintimal stenting can cause chronic total occlusion. Angiography images of previously treated CTO cases should be carefully monitored. To avoid placing a stent in the false lumen, it must be absolutely sure that it is inside the lumen. In this case, we presented a successful case of chronic total occlusion in the right coronary artery with a subintimal stent. [Med-Science 2020; 9(3.000): 796-8

Chorzy trudni nietypowi Istotne zwężenie proksymalnej części lewej tętnicy podobojczykowej objawiające się brakiem tętna na tętnicy promieniowej lewej i nawracającymi bólami wieńcowymi po operacji pomostowania wieńcowego

Stenosis of the subclavian artery, before the left internal mammary artery branch, is an important problem for patients who have undergone coronary artery bypass grafting, with an incidence rate of 0.5-1.1%. In this paper, a case of left subclavian artery stenosis, which developed after coronary artery bypass surgery and led to recurrent anginal attacks in the patient, is presented

Effects of the transcatheter closure of atrial septal defect on electrocardiographic and echocardiographic parameters six months after the closure

Although percutaneous transcatheter atrial septal defect (ASD) closure (TCC) has been performed on adults for a long time there is limited data about the effects of the procedure in the literature and the majority of studies have been performed on children. The study purposed to evaluate the impact of TCC on cardiac remodeling, electrical changes and exercise capacity in adults. Transthoracic echocardiography and electrocardiography were performed one day before and six months after TCC in 27 consecutive patients who underwent successful TCC. Twenty-seven age and sex matched healthy subjects were used as control group. Right ventricular (RV) diameter (had decreased from 44±6.3 to 34±3.9; p [Med-Science 2017; 6(2.000): 213-6

SERS-active linear barcodes by microfluidic-assisted patterning

© 2020 Elsevier Inc.Simple, low-cost, robust, and scalable fabrication of microscopic linear barcodes with high levels of complexity and multiple authentication layers is critical for emerging applications in information security and anti-counterfeiting. This manuscript presents a novel approach for fabrication of microscopic linear barcodes that can be visualized under Raman microscopy. Microfluidic channels are used as molds to generate linear patterns of end-grafted polymers on a substrate. These patterns serve as templates for area-selective binding of colloidal gold nanoparticles resulting in plasmonic arrays. The deposition of multiple taggant molecules on the plasmonic arrays via a second microfluidic mold results in a linear barcode with unique Raman fingerprints that are enhanced by the underlying plasmonic nanoparticles. The width of the bars is as small as 10 μm, with a total barcode length on the order of 100 μm. The simultaneous use of geometric and chemical security layers provides a high level of complexity challenging the counterfeiting of the barcodes. The additive, scalable, and inexpensive nature of the presented approach can be easily adapted to different colloidal nanomaterials and applications
