Abnormal glycolytic metabolism contributes to angiogenic sprouting involved in atherogenesis. We investigated the potential anti-angiogenic properties of specific 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 (PFKFB3) inhibitors in endothelial cells (ECs). ECs were treated with PFKFB3 inhibitors (named PA-1 and PA-2) and their effects on metabolic and functional characteristics of ECs were investigated.

Article Synopsis
  • The study aimed to compare two strategies for administering oral P2Y inhibitors in patients with non-ST-segment elevation acute coronary syndrome undergoing invasive treatment: pre-treatment (upstream) versus administering the drugs after angiography (downstream).
  • It involved 1,449 patients and was halted due to a pre-specified rule indicating futility, as there was no significant difference in major health events between the two groups.
  • Both strategies resulted in low rates of ischemic and bleeding complications, with only a minimal numerical difference in event rates, suggesting that the timing of P2Y inhibitor administration may not greatly impact patient outcomes.

The nuclear reaction known as proton-boron fusion has been triggered by a subnanosecond laser system focused onto a thick boron nitride target at modest laser intensity (∼10^{16}W/cm^{2}), resulting in a record yield of generated α particles. The estimated value of α particles emitted per laser pulse is around 10^{11}, thus orders of magnitude higher than any other experimental result previously reported. The accelerated α-particle stream shows unique features in terms of kinetic energy (up to 10 MeV), pulse duration (∼10 ns), and peak current (∼2 A) at 1 m from the source, promising potential applications of such neutronless nuclear fusion reactions.

The risk of acute kidney injury (AKI) is a major issue after percutaneous coronary interventions (PCIs), especially in the setting of ST-elevation myocardial infarction. Preliminary data from large retrospective registries seem to show a reduction of AKI when a transradial (TR) approach for PCI is adopted. Little is known about the relation between vascular access and AKI after emergent PCI.

Objectives: To assess the clinical outcome at 1-year follow-up of real-world patients with long coronary lesions treated with the 38 mm Xience Prime (Abbott Vascular) everolimus-eluting stent (EES).

Background: Long-lesions present special challenges to the interventional cardiologists, including increased risk of restenosis, periprocedural injury, geographical miss, and stent deliverability. Indeed, results obtained with shorter stent in the treatment of simpler lesions are of limited applicability to longer stents.

Laser atherectomy might decrease procedural complications during percutaneous coronary intervention (PCI) of degenerated saphenous vein grafts (SVGs) in case of unstable or thrombotic lesions because of its ability to debulk and vaporize thrombus. We aimed at prospectively evaluating the safety and efficacy of excimer laser coronary angioplasty (ELCA) as a primary treatment strategy in consecutively unstable patients undergoing PCI of degenerated SVG lesions. Seventy-one consecutive patients with non-ST elevation acute coronary syndrome (mean age 69 ± 10 years, 66 men [89%]) undergoing PCI of degenerated SVG were enrolled in a prospective case-control registry, using 2 different distal protection devices (DPDs; FilterWire EZ [Boston Scientific, Natick, Massachusetts; n = 24] and SpiderRX [Ev3, Plymouth, Minnesota; n = 23]) or ELCA (n = 24).

The success rate of recanalization of coronary chronic total occlusion (CTO) has improved in recent years, but the clinical benefit associated with successful CTO recanalization in the drug-eluting stent (DES) era is not well known. A cohort of 317 consecutive patients (mean age 65 ± 10, 84% men) with CTOs (defined as Thrombolysis In Myocardial Infarction [TIMI] flow grade 0 and duration >3 months) of native coronary vessels in which percutaneous coronary intervention was attempted was enrolled from June 2005 to March 2009. All successful procedures (196 patients) were performed by DES implantation.

Aims: To assess the main predictors and significance of filter no-reflow (FNR) in protected saphenous vein graft (SVG) percutaneous coronary intervention (PCI) and the effect of two different filter-based devices on FNR incidence. The phenomenon of FNR has been described as a transient impairment of blood flow due to debris plugging of a filter-based device used to shield the distal microvasculature during SVG PCI.

Methods And Results: Fifty consecutive patients treated with SVG PCI were enrolled, using two different filter-based devices (FilterWire EZ™ [Boston Scientific, Natick, MA, USA] and SpiderRX® [Ev3, Plymouth, MN, USA]).

Most of the surface explosions in nuclear tests have released radioactivity to the environment in the form of bulk glassy materials originating from the melting of sandy soil in the neighbourhood of ground zero. In view of clarifying issues concerning the mechanism of formation and the radiological impact of these materials, we investigated incorporation and volume distribution of radionuclides in a typical fragment of trinitite, the glassy substance generated following the first nuclear test (Trinity Site, New Mexico, 1945). Specific activities were determined by γ-spectrometry for the most significant fission and activation products.

Postoperative ischemia may complicate cardiac surgery, despite myocardial protection and recent technical developments. Its medical management in the intensive cardiac care unit is usually efficient, although sometimes it requires the revision of the surgical site. In other cases, urgent coronary angiography and subsequent coronary stenting may resolve the situation.

As the traditional cardiovascular control laboratory has disappeared from the first-year medical school curriculum, we have recognized the need to develop another "hands-on" experience as a vehicle for wide-ranging discussions of cardiovascular control mechanisms. Using an echocardiograph, an automatic blood pressure cuff, and a reclining bicycle, we developed protocols to illustrate the changes in cardiac and vascular function that occur with changes in posture, venous return, and graded exercise. We use medical student volunteers and a professional echocardiographer to generate and acquire data, respectively.
