Multifocal versus monofocal intraocular lenses after cataract extraction. [PDF]

open access: yes, 2012
BACKGROUND: Good unaided distance visual acuity is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision, however, still requires additional refractive power, usually in the form of reading glasses ...

Electroactive Metal–Organic Frameworks for Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

Corneal stromal demarcation line after collagen cross-linking in corneal ectatic diseases: a review of the literature [PDF]

open access: yes, 2016
Collagen cross-linking (CXL) is a relatively new conservative approach for progressive corneal ectasia, which is able to strengthen corneal tissue reforming new covalent bonds.

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

open access: yesAdvanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Embolization in an adrenocortical carcinoma as palliative therapy [PDF]

open access: yes, 1999
Background: With an annual incidence of 0.2% of new cases per 100,000 inhabitants, adrenocortical carcinoma is rare. In advanced tumor only palliative treatment modalities are practicable. Because of scarcity of the tumor, standard treatment has not been

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide

open access: yesAdvanced Functional Materials, EarlyView.
The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...

Laser refractive correction of presbyopia

open access: yesIndian Journal of Ophthalmology
Presbyopia is an inevitable and progressive loss of the eye’s ability to focus on nearby objects due to aging, which affects everyone regardless of their refractive error.

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Újabb diagnosztikus és terápiás lehetőségek a refraktív sebészetben = New diagnostic and therapeutic possibilities in refractive surgery [PDF]

open access: yes, 2006
A munkacsoport tisztázta a PRK, LASIK, LASEK módszerek hatékonyságát és indikációs területeit. Megállapításra került, hogy a TOSCA, WASCA eljárás bármelyik refraktív sebészeti műtét típussal kombinálható, azonban legjobb eredményeket a myopiás szemek ...
