Superconductivity emerges from the spatial coherence of a macroscopic condensate of Cooper pairs. Increasingly strong binding and localization of electrons into these pairs compromises the condensate's phase stiffness, thereby limiting critical temperatures - a phenomenon known as the BCS-BEC crossover in lattice systems. In this study, we demonstrate enhanced superconductivity in a multiorbital model of alkali-doped fullerides (AC) that goes beyond the limits of the lattice BCS-BEC crossover.

However, the complexity associated with conducting these trials has resulted in criticism of nutrition and dietary recommendations because the strength and quality of evidence falls short of that for some pharmaceutical interventions. In this paper, we aim to promote greater awareness of the nutrition-related clinical trials that have been conducted showing ASCVD benefits and how this evidence has contributed to dietary recommendations.

We studied the effects of a typical Western diet (WD; high in refined carbohydrates, cholesterol and saturated fat), relative to a heart-healthy diet (HHD; high in unrefined carbohydrates, polyunsaturated fat and fiber, and low in cholesterol) on brain microvessel transcriptomics and brain metabolomics of the temporal region in Ossabaw minipigs. Thirty-two pigs (16 male and 16 females) were fed a WD or HHD starting at the age of 4 months for a period of 6 months.

- TTC fusion is a surgical procedure for severe hindfoot issues, and this study compares traditional methods to carbon fiber retrograde intramedullary nailing (CF RIMN) regarding effectiveness and safety.
- A retrospective study of 21 patients showed a 90% union rate, with complications like iatrogenic fractures and postoperative issues noted at 14% and 19%, respectively, while patient-reported satisfaction improved based on VAS scores.
- The results suggest that while CF RIMN is effective, its complications require careful consideration, and more extensive studies are needed for validation and understanding long-term results.
