Zanim został ministrem: o kontaktach Ryszarda Zakrzewskiego z wywiadem PRL

2017

After the Second World War Ryszard Zakrzewski (1913–1994) was a well-known exile political and social activist in Great Britain. In the late 1940s he became one of the leaders of the Polish Socialist Party in emigration. He was also active in the Polish Ex-Combatants’ Association and the Federation of Poles in Great Britain. In 1956, the intelligence of the Polish People’s Republic got interested in his person. Over the next few years Zakrzewski maintained contacts with intelligence officers, employed as diplomats at the Polish Embassy in London. Despite the fact that he was not formally recruited, he provided information about activities of certain political groups on emigration, especiall…

2010

Artykuł zawiera analizę treści informacji znajdujących się w Internecie, które dotyczą systemu informacyjno-wyszukiwawczego PEDAGOG, tworzonego przez pracowników Biblioteki Głównej Uniwersytetu Opolskiego. Znaczącą rolę w promowaniu i określaniu znaczenia danego serwisu w sieci www, w tym również bibliograficznych baz danych tworzonych przez biblioteki, odgrywają odnośniki od innych stron internetowych. Analiza ma na celu przede wszystkim określenie „ukrytej” obecności PEDAGOGA w Internecie przez ocenę hiperłączy pochodzących od innych stron internetowych, jak również omówienie treści informacji o PEDAGOGU, znajdujących się w sieci www.

Removal of Viscoelastic Substances

2000

All viscoelastics should be completely removed from the eye to reduce the likelihood of increased intraocular pressure. Should OVD retention behind the IOL occur, an unstable refraction could result. Residual high molecular viscous substance is transported away through the trabecular meshwork, with delay, possibly resulting in a protracted postoperative IOP increase. To aspirate viscoelastics various techniques as well as instruments with different aspiration/irrigation adjustments have been proposed, a few of which will be described here. Viscoelastic removal involving the simultaneous irrigation and aspiration through a single cannula (Nevyas, 1987) or two separate cannulas (Brauweiler, 1…

Steady-state levels of retinal 24S-hydroxycholesterol are maintained by glial cells intervention after elevation of intraocular pressure in the rat

2012

Purpose: Our previous studies suggested that CYP46A1 and 24S-hydroxycholesterol. (24SOH) may be associated with glaucoma. Loss of CYP46A1-expressing retinal. ganglion cells is involved in the activation of glia, and therefore possibly in the. disbalance of cholesterol. In this context, the purpose of our present work was to. emphasize the glial and longitudinal CYP46A1 expression after an interventional. glaucoma-related stress triggered by elevated intraocular pressure (IOP). Methods: Sprague–Dawley rats were submitted to laser photocoagulation of the. trabecular meshwork, limbus and episcleral veins in one eye to induce elevated IOP. Rats were euthanized at days 3, 14, 30 and 60 (n = 10 p…

Learning from the past: Mitomycin C use in trabeculectomy and its application in bleb-forming minimally invasive glaucoma surgery.

2019

Trabeculectomy has been performed since the mid-1960s and remains the gold standard for glaucoma surgery. Newer surgical options have evolved, collectively referred to as minimally invasive glaucoma surgeries. Despite producing large intraocular pressure decreases, full-thickness procedures into the subconjunctival space may be limited by fibrosis. Mitomycin C (MMC) and 5-fluorouracil have been in use with trabeculectomy with good evidence of significantly increased success at the cost, however, of an increased risk of complications. Off-label MMC application can be found in almost all clinical trials, including in combination with minimally invasive glaucoma surgeries. We explore current e…

Objective To compare surgical success, postoperative intraocular pressure and complication rates between trabeculectomy and XEN gelstent surgery in a cohort of glaucoma patients in a typical clinical setting. Methods A retrospective cohort study of consecutive patients with refractory open-angle glaucoma including patients who underwent either stand-alone XEN gelstent insertion with Mitomycin C or trabeculectomy with Mitomycin C between 2016 and 2018 at the University Eye Hospital Mainz, Germany. Primary outcome measure was the proportion of surgical success 1 year after surgery. Patients with an IOP ≤18mmHg, an intraocular pressure reduction of >20% and in no need of revision surgery or to…

Comparison of subconjunctival microinvasive glaucoma surgery and trabeculectomy

2021

Purpose To assess surgical success and the post-operative development of intraocular pressure between XEN45® gelstent, Preserflo® MicroShunt and trabeculectomy with mitomycin C. Methods Data from 105 eyes from 105 patients of matched cases with refractory open-angle glaucoma, who underwent surgery between January 2019, and August 2020, were evaluated. Patients underwent either stand-alone XEN gelstent insertion with Mitomycin C, stand-alone Preserflo with Mitomycin C or trabeculectomy with Mitomycin C. The primary outcome was the proportion of complete surgical success at 6 months post-operatively (i.e. intraocular pressure between 5mmHg and 18mmHg, no revision surgery, no loss of light per…

Trabeculotomy in congenital glaucoma.

2000

Background: Congenital glaucoma is a potentially blinding disease that requires surgical therapy. This paper describes the outcome of trabeculotomy in primary congenital glaucoma. Methods: Thirty-nine eyes of 22 children with congenital glaucoma who underwent trabeculotomy with or without a simultaneous trabeculectomy between 1992 and 1997 were retrospectively analyzed. Results: Mean follow-up was 24.7±17.9 months. A mean of 1.3 operations per eye were performed. The mean IOP at the end of follow-up (n=39) was 17.7±6.0 mmHg; in 8 eyes (20.5%) the IOP was >21 mmHg, in 31 eyes (79.5%) it was ≤21 mmHg. The mean difference between pretreatment IOP and IOP at the end of follow-up (n=39) was –10.…

The Impact of Depression Symptoms in Patients with Parkinson’s Disease: A Novel Case-Control Investigation

2021

Parkinson’s disease is a common neurodegenerative disease and it is known to cause motor disturbances associated with musculoskeletal problems of the locomotor apparatus, and non-motor symptoms, that are believed to have a harmful effect on health, social functioning and mobility. The aim of this study was to evaluate depression in patients with Parkinson’s Disease (PD) compared to subjects who do not have it. The sample consisted of 124 participants (mean age 69.18 ± 9.12). Patients with PD were recruited from a center of excellence for Parkinson’s disease (cases n = 62) and healthy subjects without PD from their relatives and caregivers (control n = 62). The Spanish version of Beck’s Depr…
