The effect of blue-light-blocking lenses on retinal straylight

2021

Sometimes yellow-tinted lenses are recommended to help improve visual quality. As yellow lenses filter blue light, it is believed that their use could decrease the intensity of scattered light in the eye (retinal straylight). However, the results of some studies have contradicted this assumption (Van Os et al. 2017). Currently various nontinted blue-light-blocking lenses are used to protect the eyes from short-wavelength light. The objective of this study was to determine whether blue-light-blocking lenses affect the levels of retinal straylight in the eye. A straylight meter (C-Quant, Oculus) was used for retinal straylight measurements. The measurements were performed under four different…

Optical quality of hyperopic and myopic phakic intraocular lenses

2013

Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…

A boy with oral hair: Case report

2007

In personal communication we have never seen or heard of hair being detected in the oral cavity. Even Julia Pastrana, the famous ?Bearded Lady? of the 1800?s, had no record of oral hair, although her entire body was covered with hair. Extensive records of her oral condition, including plaster models of her teeth have been preserved in the Odontological Museum of the Royal College of Surgeons in London city. She suffered from excessive gingival hyperplasia, but apparently no hair existed within the mouth. Some rodents have oral hair as a normal occurrence, but the condition is apparently limited in the animal kingdom. A case of hair occurring naturally in the mouth has been reported only twi…

Third canal in the mesial root of permanent mandibular first molars: Review of the literature and presentation of 3 clinical reports and 2 in vitro s…

2007

Introduction. Systematic anatomical studies corroborate the anatomical complexity of the root canal system. Deviations from the norm such as multiple orifices, apical deltas, accessory canals and other variations are frequent. Objectives. To present clinical reports of mandibular molars with three canals in the mesial root and two in vitro studies of the morphology of these canals, together with a review of the literature. Materials and Methods. Three clinical reports are presented of mandibular molars where three canals in the mesial roots were treated endodontically. Two in vitro studies were performed, one using computerized tomography and the other with scanning electron microscopy, to …

Making Sense or Betting on the Future? : Identifying Antenarratives of AI projects in a Large Financial Organization

2019

The future is uncertain, but what is certain is that we can make sense of the future through our ‘antenarratives’. In this study, I shed light on prospective sensemaking and apply the concept of antenarrative as a framework to identify how strategy practitioners make sense of AI projects. The empirical case organization is a large Finnish financial organization that aims to be a digital leader. The case organization is currently developing and implementing AI in its business operations, a recent and emerging wave in the financial business sector. Following a thematic analysis, the narratives that seem to either reflect positive (that promote) or negative (that impede) changes were examined.…

Child Well-Being in Times of Confinement: The Impact of Dialogic Literary Gatherings Transferred to Homes

2020

The COVID-19 pandemic has created an unexpected situation that has forced people to find educational alternatives to support learning and ensure child well-being. The need for practices that 'open doors' at home as a way to promote a quality education and to foster an environment of supportive relationships and a sense of community, has led to the in-depth analysis of successful educational actions, particularly the Dialogic Literary Gatherings (DLGs). The aim of this article is to show how the transference of DLGs to the home environment has had an impact on child subjective well-being in times of confinement, promoting a safe and supportive environment for learning, interacting, coexistin…

Crystalline wax coverage of the imaginal cuticule in Calopteryx splendens (Odonata: Calopterygidae)

2009

In this study we use high resolution SEM to describe the diversity of wax crystals and their distribution on different morphological structures in male individuals of Calopteryx splendens. The entire cuticle surface of this damselfly, with the exception of ommatidia and ocelli, is covered with crystalline wax in dimensions from submicron to micron range. It is shown that shape – rod-like, plate like, filamentous, etc. –, size, and density of crystals vary on different surfaces and in individuals of different ages. Additionally, we demonstrate different types of damage to the crystalline wax layer: scratches, compressions, wear, and contamination. The primary function of the wax crystalline …

Zachowania zdrowotne a poczucie własnej skuteczności i kontrola emocji u pacjentów z chorobami nowotworowymi

2018

Wprowadzenie. Indywidualne cechy osobowości każdego człowieka warunkują odmienną reakcję na wiadomość o chorobie nowotworowej, wpływają na wyniki jej leczenia, dalsze rokowanie, a także jakość życia chorego. W tym kontekście istotną rolę odgrywają zdolności kontroli emocji oraz poczucie własnej skuteczności, które jest siłą przekonania, że poprzez realizację określonych działań można osiągnąć wyznaczone cele. Cel. Ocena związku pomiędzy poczuciem własnej skuteczności, kontrolą emocji a zachowaniami zdrowotnymi u pacjentów cierpiących z powodu choroby nowotworowej. Materiały i metody. Badaniem objęto 148 chorych leczonych onkologicznie, którzy odpowiedzieli na pytania zawarte w metryczce ora…
