Is Ranibizumab effective in stopping loss of vision secondary to Choroidal Neovascularization in Pathologic Myopia? A Long Term Follow-up Study.

2011

Purpose: To assess the efficacy and safety of Ranibizumab in the treatment of choroidal neovascularization (CNV) caused by pathologic myopia (PM). Design: Prospective, multicenter, interventional case series. Methods: 40 of 39 consecutive patients with PM and CNV were treated with “on-demand” intravitreal injection of ranibizumab 0.5 mg. Final best-corrected VA (BCVA) and its change from baseline were the main outcome measures. Changes in Optical Coherence Tomography (OCT) central retinal thickness (CRT) were a secondary outcome. Results: Mean age was 53 ± 13 years, mean refractive error -13.5 ± 6.5 diopters. Median follow-up was 13.3 ± 2 months (range 12 – 18). Fifteen eyes (37.5%) had pre…

Adhesive capsulitis of the shoulder: laser CO2 vs intra-articular injections

2012

Analysis of our data shows that the functional rehabilitation associated with the CO2 laser causes a greater reduction in pain, better recovery of joint ROM and increase in muscle strength compared to treatment associated with injections of corticosteriods

An Automatic System for the Analysis and Classification of Human Atrial Fibrillation Patterns from Intracardiac Electrograms

2008

This paper presents an automatic system for the analysis and classification of atrial fibrillation (AF) patterns from bipolar intracardiac signals. The system is made up of: 1) a feature- extraction module that defines and extracts a set of measures potentially useful for characterizing AF types on the basis of their degree of organization; 2) a feature-selection module (based on the Jeffries-Matusita distance and a branch and bound search algorithm) identifying the best subset of features for discriminating different AF types; and 3) a support vector machine technique-based classification module that automatically discriminates the AF types according to the Wells' criteria. The automatic s…

Neue Therapieoption für akute hepatische Porphyrien

2021

Was ist neu? Therapie mit Givosiran Givosiran ist ein kleines synthetisches doppelsträngiges siRNA-Fragment mit 20 Basenpaaren Länge. Eine prospektive, randomisierte multizentrische Studie (Envision) zeigte erstmalig die klinische Wirksamkeit von monatlich subkutan applizierten synthetischen RNA-Molekülen („small interfering“ RNA, siRNA) zur Prävention von Attacken bei akuten hepatischen Porphyrien (AHP) 2. Die Koppelung von siRNA-Molekülen an N-Acetyl-Galaktosamin (GalNAc) und die hierdurch leberspezifische Aufnahme durch den Asialoglykoprotein-Rezeptor auf Hepatozyten sind ein Meilenstein in der Hepatologie. Dies führt zu einer hochselektiven Inhibition der Translation der bei AHP überexp…

LC of high to moderately polar basic drugs in urine with water and detergent, and direct injection

2016

Background: Micellar LC was first proposed as a ‘green’ mode using mobile phases of water and surfactant. However, in most procedures a small amount of organic solvent is required to decrease the retention to convenient values. Results & methodology: Mixed micellar mobile phases prepared with both cationic (sodium dodecyl sulphate) and nonionic surfactant (Brij-35) modulate the retention of high to moderately polar basic drugs to practical times, eliminating the need of organic solvent. While the mobile phase is continuously recycled through the system, the stationary phase performance is maintained after repetitive injection of the samples. Discussion & conclusion: Through an exte…

The origin of slow electron recombination processes in dye-sensitized solar cells with alumina barrier coatings

2004

We investigate the effect of a thin alumina coating of nanocrystalline TiO2 films on recombination dynamics of dye-sensitized solar cells. Both coated and uncoated cells were measured by a combination of techniques: transient absorption spectroscopy, electrochemical impedance spectroscopy, and open-circuit voltage decay. It is found that the alumina barrier reduces the recombination of photoinjected electrons to both dye cations and the oxidized redox couple. It is proposed that this observed retardation can be attributed primarily to two effects: almost complete passivation of surface trap states in TiO2 that are able to inject electrons to acceptor species, and slowing down by a factor of…

State selective electron injection in non-aggregated titanium phthalocyanine sensitised nanocrystalline TiO2 films

2004

We describe a novel titanium phthalocyanine that shows no aggregation when anchored to nanocrystalline TiO2 films through its axial carboxylated ligand without the use of co-adsorbents; state selective electron injection into the TiO2 is demonstrated, resulting in efficient photocurrent generation in dye sensitised photoelectrochemical solar cells.
