Role of the androgen receptor in melanoma aggressiveness.

Malignant melanoma represents the fifth most common cancer in the world and its incidence is rising. Novel therapies targeting receptor tyrosine kinases, kinases and immune checkpoints have been employed with a significant improvement of the overall survival and long-term disease containment. Nevertheless, the disease often progresses and becomes resistant to the therapies.

A review of optical and thermal eye tissue parameters for improved computational models in retinal laser therapy.

Laser surgery is recognized as a highly effective method for managing retinal diseases. However, the thermal effects of the laser on different eye tissues are not entirely understood yet. In this context, computational modeling can be a useful tool to predict therapy outcomes.

Impact of Open Surgical Descending Repair on Aortic Stiffness in an Ex Vivo Porcine Model.

Background: Previous studies have strongly suggested that stent-graft deployment and acute arch angulation increase aortic stiffness, the impact of surgical interposition grafting remains unclear. We investigated the impact of open surgery on aortic stiffness and compared this with stent-graft induced aortic stiffening, utilising an ex vivo model.

Methods: Porcine thoracic aortas were connected to a mock circulatory loop.

Bicuspid Valve Aortopathy: Is It Reasonable to Define a Different Surgical Cutoff Based on Different Aortic Wall Mechanical Properties Compared to Those of the Tricuspid Valve?

Background: In this study, we examined and compared ex vivo mechanical properties of aortic walls in patients with bicuspid (BAV) and tricuspid (TAV) aortic valve aortopathy to investigate if the anatomical peculiarities in the BAV group are related to an increased frailty of the aortic wall and, therefore, if a different surgical cutoff point for ascending aortic replacement could be reasonable in such patients.

Methods: Ultimate stress tests were performed on fresh aortic wall specimens harvested during elective aortic surgery in BAV (n. 33) and TAV (n.

Experimental and Numerical Integrated Strategy for the Optimization of Microfluidic Parameters for Eudragit L100 Nanoparticles and Microparticles.

Oral immunization offers a minimally invasive administration, inducing local and systemic immune responses and facilitating mass immunization without needle-related risks. However, the gastrointestinal environment poses challenges, compromising vaccine effectiveness through enzymatic degradation and poor absorption by Peyer's patches. Advances in nanoparticle and microparticle (NP/MP) technology protect vaccines from degradation and enhance targeted release.
