Density functional theory (DFT) functionals for calculations of binding energies (BEs) the polyethylene (PE) chains cross-linked by selected metal atoms (M) are benchmarked against DLPNO–CCSD(T) and DLPNO–CCSD(T1) data. PEX-M-PEX complexes as compared with plain parallel PEX···PEX X = 3–9 carbon model species characterized a cooperative effect covalent C-M-C bonds interchain dispersion interact...

A female patient affected by a thrombotic syndrome due to non SLE-related antiphospholipid antibodies (APA), developed a serious, non inflammatory, thrombotic macroangiopathy and uremic-hemolytic syndrome during oral anticoagulant therapy. She was treated with aspirin, dipyridamole i.v. and with a total of 14 fresh frozen plasma exchange (PEX), but the thrombotic syndrome only showed a partial ...

Pseudoexfoliation (PXF) syndrome is a genetically determined, age-dependent generalized disorder of the elastic fiber system, characterized by excessive production and accumulation of an elastotic material within a multitude of intraand extraocular tissues. Accumulation of this abnormal material in the aqueous humor outflow pathways predisposes to ocular hypertension and development of a severe...

The histochemical staining properties of the abnormal material deposited in the anterior segment of the eye in the pseudoexfoliation syndrome and the zonular ligaments of the lens are essentially the same. Both present the staining characteristics of oxytalan, the microfibrillar component of elastic tissue. Reasons are advanced for regarding the pseudoexfoliative material as a product of the ci...

Crystalline lens dislocation and zonular dialysis during intraocular surgery are recognised features of the pseudoexfoliation syndrome (PES). A case is reported in which zonular dialysis occurred in both eyes during extracapsular cataract extraction. In particular surgery was complicated by difficulty in performing anterior capsulotomy. Careful preoperative assessment and peroperative technique...
