The Internuclear Ophthalmoplegias
1993
Internuclear ophthalmoplegia (INO), which is caused by an ipsilateral medial longitudinal fasciculus (MLF) lesion, is characterized by adduction paresis of lateral gaze, usually with spared convergence [1–4]. In the opposite eye, abduction nystagmus and hypermetric abduction saccades are the main clinical and electro-oculographic abnormalities [1, 5, 6]. The origin of both is still debated. Abduction nystagmus has been explained by (a) an additional horizontal gaze paresis [7]; (b) vergence mechanisms aimed at alignment of the visual axes [8]; (c) interruption of descending excitatory projections from oculomotor nucleus internuclear neurons to contralateral abducens nucleus motoneurons [9];…
Diabētiskā retinopātija. Saistība ar metabolo kompensāciju, diabēta ilgumu, un citām mikro un makrovaskulārām komplikācijām 1. tipa cukura diabēta pa…
2018
Diabētiskā retinopātija ir nopietna komplikācija, kas skar ļoti daudz 1. tipa cukura diabēta pacientus. Tādēļ darba galvenais mērķis ir pierādīt diabēta retinopātijas attīstības smagumu atkarībā no CD ilguma un metabolās kompensācijas, kā arī retinopātijas saistību ar citām mikro un makrovaskulārajām komplikācijām, lai iegūtu lielāku priekšstatu par to, kas ir šīs komplikācijas veicinošie faktori un ar ko tā mēdz pastāvēt kopā. Materiāli un metodes: pētījumā retrospektīvi tika analizētas slimības vēstures pacientiem, kas slimo ar 1TCD no 2016.g janvāra līdz 2018.gada martam Paula Stradiņa Klīniskajā Universitātes slimnīcā. Pētījumā iekļauti 79 (158 acis) pacienti. Datu statistiskai apstrāde…
Glaucomatous Maculopathy: Thickness Differences on Inner and Outer Macular Layers between Ocular Hypertension and Early Primary Open-Angle Glaucoma U…
2020
The purpose of this study was to compare the thickness of all inner and outer macular layers between ocular hypertension (OHT) and early primary open-angle glaucoma (POAG) using spectral domain optical coherence tomography (SD-OCT) 8 × 8 posterior pole algorithm (8 × 8 PPA). Fifty-seven eyes of 57 OHT individuals and fifty-seven eyes of 57 early POAG patients were included. The thickness of macular retinal nerve fiber layer (mRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform and nuclear layer, photoreceptor layer (PRL) and retinal pigment epithelium were obtained in 64 cells for each macular layer and mean thickness of superior and inf…
Akomodācijas atbildes saistība ar heteroforijas un ametropijas veidiem
2019
Maģistra darbs ir uzrakstīts latviešu valodā uz 41 lapaspuses. Tas satur 24 attēlus, 3 tabulas un 48 atsauces uz literatūras avotiem. Darba mērķis: noteikt akomodācijas atpalikšanu monokulāros un binokulāros apstākļos un tās saistību ar refrakcijas veidu un heteroforijas veidu. Dalībnieki: 21 dalībnieks ar emetropiju, 21 dalībnieks ar miopiju. Metode: Akomodācijas atpalikšana tika noteikta ar MEM un Nott dinamisko retinoskopiju un ar ekscentrisko fotorefraktometru. Heteroforija tika mērīta ar Madox rod un Madox wing testiem. Rezultāti: Ametropijas un heteroforijas veids neietekmē akomodācijas atpalikšanas lielumu. Nav statistiski nozīmīgas atšķirības starp akomodācijas atpalikšanu monokulār…
Perceived development opportunities and reward satisfaction as antecedents of nurses’ job withdrawal intentions
2016
Retention of nurses has received considerable attention in recent years due to the ageing population and the shortage of nurses. However, most of the studies have concentrated on either older nurses’ early retirement or younger nurses’ turnover intentions. This study analyses the antecedents of different forms of job withdrawal intentions with special reference to perceived development opportunities and reward satisfaction. A quantitative survey was conducted among nurses in one Finnish University hospital. A total of 510 nurses completed the questionnaire, representing a 54.4% response rate. The results demonstrated that job withdrawal intentions were relatively common and age-dependent am…
Stromal Interaction Molecule 1 (STIM1) Is Involved in the Regulation of Mitochondrial Shape and Bioenergetics and Plays a Role in Oxidative Stress
2012
Calcium ions are involved in a plethora of cellular functions including cell death and mitochondrial energy metabolism. Store-operated Ca(2+) entry over the plasma membrane is activated by depletion of intracellular Ca(2+) stores and is mediated by the sensor STIM1 and the channel ORAI1. We compared cell death susceptibility to oxidative stress in STIM1 knock-out and ORAI1 knockdown mouse embryonic fibroblasts and in knock-out cells with reconstituted wild type and dominant active STIM1. We show that STIM1 and ORAI1 deficiency renders cells more susceptible to oxidative stress, which can be rescued by STIM1 and ORAI1 overexpression. STIM1 knock-out mitochondria are tubular, have a higher Ca…
Retinal Microcirculation in Type 1 Diabetic Patients With and Without Peripheral Sensory Neuropathy
2014
In patients with diabetes mellitus (DM), early retinal microvascular alterations can be observed even before the clinical diagnosis of diabetic retinopathy. This study aimed to investigate morphological and functional changes in retinal microvascular blood flow in type 1 diabetic patients with and without peripheral neuropathy (PNP) as compared to nondiabetic controls. Retinal microvascular blood flow (RBF) was assessed using scanning laser Doppler flowmetry (Heidelberg Retina Flowmeter, Heidelberg Engineering, Germany) before and after stimulation with flicker light. PNP was assessed using the neuropathy disability score (NDS) and by the evaluation of the vibration perception threshold (V…

Linee guida per l'interpretazione ambientale delle aree protette
2008
Le aree protette, viste dapprima come vincolo dalle popolazioni locali che vi risiedono, hanno acquisito sempre più il ruolo di laboratorio per la sperimentazione di nuove politiche di gestione virtuosa del territorio. Oggi rappresentano luoghi in cui è possibile ricucire il legame tra sviluppo economico, sociale e ambientale attraverso l’arresto dell’uso indiscriminato e irresponsabile delle risorse naturali e l’avvio di processi economici e sociali basati sugli scopi dello sviluppo sostenibile. L’Interpretazione Ambientale rappresenta, all’interno delle politiche di gestione delle aree protette, lo strumento adeguato a progettare e contemperare la fruizione con la conservazione e la tutel…
Intentions of early retirement and continuing to work among middle-aged and older employees
2009
The purpose of this study is to investigate personal, health, work, and work-related psychological factors in association with employee intentions of early retirement and continuing to work after retirement in the form of bridge employment. In addition, the study aims to further our understanding of what motivates older employees by investigating age-related differences in employee reward preferences. The study draws upon several theoretical perspectives, including continuity theory, the life course perspective, theories on motivation, and the meaning of work for older employees. Survey data from three individual research projects are used in this study - age management studies consisting o…
