Congenital stationary night blindness : an update and review of the disease spectrum in Saudi Arabia

Congenital stationary night blindness (CSNB) is a group of rare, mainly stationary disorders of the retina, resulting from dysfunction of several specific and essential visual processing mechanisms. The inheritance is often recessive and as such, CSNB may be more common among populations with a high degree of consanguinity. Here, we present a topic update and a review of the clinical and molecular

Effect of early discharge after planned cesarean section on recovery and parental sense of security. A randomized clinical trial

Introduction: In some European countries, discharge the day after planned cesarean section has become an accepted procedure. However, little is known about the patients’ perception of early discharge. The aim of this study was to compare early discharge with standard care in relation to parental sense of security. Further, we evaluated postoperative pain, mobilization, and readmission. Material an

Star turnover and the value of human capital-evidence from broadway shows

Theater shows routinely turn over actors in lead roles. Otherwise, the show stays the same, including the director, the script, other actors and, the physical theater environment. Even the lines performed do not change the set. Therefore, the theater provides a unique laboratory for assessing the value of human capital to an enterprise, a question that has been studied in other contexts, including

Optical Force-Induced Dynamics of Assembling, Rearrangement, and Three-Dimensional Pistol-like Ejection of Microparticles at the Solution Surface

Optical trapping and assembling dynamics of polystyrene microparticles (MPs) of 1 μm in diameter are studied at its solution-air surface using a widefield microscope. Upon switching on the intense 1064 nm laser, the MPs are gathered, forming a single concentric circle (CC)-like assembly larger than the focus. It consists of a few tens of MPs, and the central part of the assembly shows structural c

Enforcing the General Planar Motion Model : Bundle Adjustment for Planar Scenes

In this paper we consider the case of planar motion, where a mobile platform equipped with two cameras moves freely on a planar surface. The cameras are assumed to be directed towards the floor, as well as being connected by a rigid body motion, which constrains the relative motion of the cameras and introduces new geometric constraints. In the existing literature, there are several algorithms ava

Thermal analysis of a high-power glow discharge in flowing atmospheric air by combining Rayleigh scattering thermometry and numerical simulation

The thermal state of a glow discharge with intermediate current in flowing atmospheric air is investigated by a combination of Rayleigh scattering thermometry imaging and numerical simulation. Results from the simulation indicate that during the initial breakdown the local translational temperature can reach a huge value (e.g. 6000 K) but decreases quickly due to strong heat transfer to the surrou

Persuasive Argumentation and Epistemic Attitudes

This paper studies the relation between persuasive argumentation and the speaker’s epistemic attitude. Dung-style abstract argumentation and dynamic epistemic logic provide the necessary tools to characterize the notion of persuasion. Within abstract argumentation, persuasive argumentation has been previously studied from a game-theoretic perspective. These approaches are blind to the fact that, i

Current Trends in Development of Photosynthetic Bioelectrochemical Systems for Light Energy Conversion

During the past few decades, intensive research has been focused on the application of biological photosynthetic processes for "green" electrical power generation. In this contribution, we consider different possible photobiocatalysts, such as isolated photosystems, thylakoid membranes (TMs), and whole photosynthetic organisms suitable for building bioelectrochemical systems for light energy conve

Amyloid-specific extraction using organic solvents

Typing of amyloidosis by mass spectrometry (MS) based proteomic analysis contribute to the diagnosis of amyloidosis. For MS analysis, laser microdissection (LMD) is used for amyloid specific sampling. This study aimed to establish a method for selectively extracting amyloids from formalin-fixed, paraffin-embedded (FFPE) specimens by organic solvent instead of LMD. The extracts using dimethyl sulfo

Apolipoprotein E interferes with IAPP aggregation and protects pericytes from IAPP-Induced Toxicity

Apolipoprotein E (ApoE) has become a primary focus of research after the discovery of its strong linkage to Alzheimer’s disease (AD), where the ApoE4 variant is the highest genetic risk factor for this disease. ApoE is commonly found in amyloid deposits of different origins, and its interaction with amyloid-β peptide (Aβ), the hallmark of AD, is well known. However, studies on the interaction of A

Disability, Sociodemographics, and Discrimination: A Descriptive Analysis of Household Survey Data from Bangladesh

Purpose: Disability affects upwards of one billion people worldwide, the majority of whom live in low- and middle-income countries. Based on survey data from Bangladesh, the aim of the study is to contribute to an improved understanding of the experiences of people with disabilities in terms of discrimination, health, and sociodemographic indicators. Method: A descriptive analysis of data is prese

Exclusive photoproduction of excited quarkonia in ultraperipheral collisions

In this paper, we discuss the exclusive photoproduction of ground and excited states of ψ(1S,2S) and ϒ(1S,2S) in ultraperipheral collisions (UPCs). Using the potential model in order to obtain the vector meson wave function, we find a good agreement of our calculations with data from the LHC and HERA colliders for J/ψ(1S,2S) and ϒ(1S) in γp collisions. We extend the calculations to the nuclear tar

Effects of dipeptidyl peptidase 4 inhibition on inflammation in atherosclerosis : A 18F-fluorodeoxyglucose study of a mouse model of atherosclerosis and type 2 diabetes

Background and aims: Dipeptidyl peptidase 4 (DPP-4) inhibitors have anti-inflammatory and atheroprotective effects. We evaluated the effects of the DPP-4 inhibitor linagliptin on atherosclerotic plaque and hepatic inflammation using histology and 2-deoxy-2-[18F]-fluoro-D-glucose (18F-FDG), a positron emission tomography tracer of inflammation, in a mouse model of hypercholesterolemia and type 2 di

Anxiety, fear, and ontological security in world politics : Thinking with and beyond Giddens

Research on ontological security in world politics has mushroomed since the early 2000s but seems to have reached an impasse. Ontological security is a conceptual lens for understanding subjectivity that focuses on the management of anxiety in self-constitution. Building especially on Giddens, IR scholars have emphasized how this translates to a need for cognitive consistency and biographical cont

Incretin hormones, insulin, glucagon and advanced glycation end products in relation to cognitive function in older people with and without diabetes, a population-based study

Aim: The aim of this observational study was to investigate relationships between physiological levels of glucometabolic biomarkers and cognitive test results in a population-based setting. Methods: Cross-sectional data were obtained from the Swedish population-based Malmö Diet and Cancer Study Re-examination 2007–2012 comprising 3001 older people (mean age 72 years). Through oral glucose toleranc

Poor Little Rich Kids? The Role of Nature versus Nurture in Wealth and Other Economic Outcomes and Behaviours

Wealth is highly correlated between parents and their children; however, little is known about the extent to which these relationships are genetic or determined by environmental factors. We use administrative data on the net wealth of a large sample of Swedish adoptees merged with similar information for their biological and adoptive parents. Comparing the relationship between the wealth of adopte

Optimization of the Dental Direct Digital Imaging by Applying the Self-Recognition Technology

This paper is intended to introduce the technology to solve some of the deficiencies of the direct digital radiology. Nowadays, digital radiology is the latest progression in dental imaging, which has become an essential part of dentistry. There are two main parts of the direct digital radiology comprised of an intraoral X-ray machine and a sensor (digital image receptor). The dentists and the den

Identification of on- And off-pathway oligomers in amyloid fibril formation

The misfolding and aberrant aggregation of proteins into fibrillar structures is a key factor in some of the most prevalent human diseases, including diabetes and dementia. Low molecular weight oligomers are thought to be a central factor in the pathology of these diseases, as well as critical intermediates in the fibril formation process, and as such have received much recent attention. Moreover,
