We describe successful percutaneous coronary intervention (PCI) of significantly diseased ostial left main (LM) and distal LM bifurcation (Medina 1,1,1) in a patient with a reduced left ventricular ejection fraction and a recent valve-in-valve balloon-expandable TAVR using the DK-Crush technique with the support of a percutaneous left ventricular assist device.

Taurodontism is a rare dental anomaly presented with an aberration of teeth that lacks the constriction at the level of the cemento-enamel junction (CEJ). It is characterized by elongated pulp chambers and apical displacement of bifurcation or trifurcation of the roots, forming a rectangular shape. Whilst, it appears most frequently as an isolated anomaly, its association with several syndromes and abnormalities has also been reported in the literature. Although permanent molars are most commonly affected, this anomaly could also be seen in deciduous dentition, unilaterally or bilaterally, and in any combination of teeth or quadrants. These morphological anomalies pose various challenges to the dentist during their endodontic treatment. Modern diagnostic tools such as Cone beam computed tomography (CBCT), loupes and Dental operating microscopes (DOM) help in achieving better treatment outcome in such cases. The presented article elaborates diagnosis and successful management of 2 rare cases of taurodontism in permanent molars.

Severe aorto-iliac occlusive disease: Options beyond standard aorto-bifemoral bypass

  • Konstantinos Filis*, Constantinos Zarmakoupis, Fragiska Sigala and George Galyfos

According to recent guidelines, endovascular angioplasty is the standard treatment for TASC A and B primary aorto-iliac occlusive (AIOD) disease, and the first-line approach for TASC C lesions [1,2]. Extended TASC D occlusive disease is usually treated by open surgery yielding excellent patency rates at a cost of a higher mortality (2%-4%) and a severe morbidity (up to 10%) [3]. However, several studies have reported promising results after endovascular treatment of extensive AIOD and full reconstruction of the aortic bifurcation [4,5]. In a recent meta-analysis, Jongkind et al., concluded that endovascular treatment of extensive AIOD can be performed successfully by experienced interventionists in selected patients [6]. Although primary patency rates seem to be lower than those reported for surgical revascularization, reinterventions can often be performed percutaneously yielding a secondary patency comparable to surgical repair.

Bifurcations and control studies in Circadian Rhythms in Drosophila

  • Lakshmi N Sridhar*

Published on: 7th February, 2025

Bifurcation analysis and Multiobjective Nonlinear Model Predictive Control (MNLMPC) calculations were performed on a model of circadian oscillations of the Period (PER) and Timeless (TIM) proteins in Drosophila. The MATLAB program MATCONT was used to perform the bifurcation analysis. The optimization language PYOMO was used along with the state-of-the-art global optimization solvers IPOPT and BARON for the MNLMPC calculations. The bifurcation analysis revealed oscillation causing Hopf bifurcations while the MNLMPC calculations revealed the existence of spikes in the control profiles. Both Hopf bifurcation points and the control profile spikes were eliminated using an activation factor involving the hyperbolic tangent function.
