Polyetheretherketone (PEEK) materials belong to a group of high-performance thermoplastic polymers thermoplastic that has been proposed as a substitute for metals in biomaterials.In this research, in order to improve the performances of PEEK, nano titanium dioxide (n-TiO2) and nano-hydroxyapatite (n-HAp) were incorporated into PEEK loading up to (1
Introduction Glaucoma is a heterogeneous group of conditions which result in optic Caddies/Cart neuropathy and visual defects, majorly linked with the increase of intra-ocular pressure (IOP).It is known that psychotropic drugs have been implicated in drug induced angle-closure glaucoma, mostly through its anti-cholinergic effect.Objectives Systemat
Modern urbanism is called to face current challenges ranging from intensive demographic growth, economic and social stagnation to resources salvation and climate changes.Under the broader scope of sustainability, we argue that the transition to a holistic perspective of smart and regenerative planning and design is the way to face and yet to preven
In this paper, we propose an original complex network model for an epidemic problem in an heterogeneous geographical area.The complex network is constructed by coupling nonidentical instances of a HIV/AIDS epidemiological model for which a disease-free equilibrium and an endemic equilibrium can Latte Capelli coexist.After proving the existence of a
Summary: An evolving family of mobile colistin resistance (MCR) enzymes is threatening public health.However, the molecular mechanism by which the MCR enzyme as a rare member Accessories of lipid A-phosphoethanolamine (PEA) transferases gains the ability to confer phenotypic colistin resistance remains enigmatic.Here, we report an unusual example t
