Protein allosteric site identification using machine learning and per amino acid residue reported internal protein nanoenvironment descriptors.

Allosteric regulation plays a crucial role in modulating protein functions and represents a promising strategy in drug development, offering enhanced specificity and reduced toxicity compared to traditional active site inhibition. Existing computational methods for predicting allosteric sites on proteins often rely on static protein surface pocket features, normal mode analysis or extensive molecular dynamics simulations encompassing both the protein function modulator and the protein itself. In this study, we introduce an innovative methodology that employs a per amino acid residue classifier to distinguish allosteric site-forming residues (AFRs) from non-allosteric, or free residues (FRs).

Calcium phosphate and titanium cranioplasty after total angular craniopagus separation.

Craniopagus separation requires careful planning and a multi-staged surgical approach, managed by a multidisciplinary team. Despite growing experience on surgical management, the long-term restoration of the cranial defect has been rarely discussed so far. Several alloplastic materials have been proposed as effective and safe solutions for cranioplasty even for pediatric patients, allowing for bone generation, good aesthetic results, and low complication rates.

Vertical Hemispherotomy: Contribution of Advanced Three-Dimensional Modeling for Presurgical Planning and Training.

Vertical hemispherotomy is an effective treatment for many drug-resistant encephalopathies with unilateral involvement. One of the main factors influencing positive surgical results and long-term seizure freedom is the quality of disconnection. For this reason, perfect anatomical awareness is mandatory during each step of the procedure.

Combining 3-Dimensional Electroanatomic Mapping and Cardiac Magnetic Resonance: A New Tool for Arrhythmogenic Cardiomyopathy.

We present the case of a 17-year-old asymptomatic boy with a diagnosis of arrhythmogenic cardiomyopathy. Merging of cardiac magnetic resonance imaging and three-dimensional electroanatomic mapping provided striking visualization of the association between structural and electrical alterations and guided the decision to implant an implantable cardioverter defibrillator.

3D bioprinting in airway reconstructive surgery: A pilot study.

Objectives: Open surgery is a reliable choice for congenital subglottic stenosis, that represents the third most common congenital anomaly of the larynx. One of the procedures performed is anterior laryngotracheal reconstruction (LTR) with anterior rib graft. The objective of this preliminary study was to evaluate the potential of 3D printing technology for the realization of laryngo-tracheal scaffold in Polycaprolactone (PCL) implanted in vivo in ovine animal model.
