Tear menisci and corneal subbasal nerve density in patients after laser in situ keratomileusis

Objective: To investigate the relationship between tear menisci and corneal nerve density in patients after laser in situ keratomileusis (LASIK). Methods: Twenty-eight eyes of 14 myopic patients were enrolled. Height and area of the upper and lower tear menisci—upper tear meniscus height, upper tear meniscus area, lower tear meniscus height (LTMH), and lower tear meniscus area (LTMA)—were measured

The FANCM:p.Arg658* truncating variant is associated with risk of triple-negative breast cancer

Breast cancer is a common disease partially caused by genetic risk factors. Germline pathogenic variants in DNA repair genes BRCA1, BRCA2, PALB2, ATM, and CHEK2 are associated with breast cancer risk. FANCM, which encodes for a DNA translocase, has been proposed as a breast cancer predisposition gene, with greater effects for the ER-negative and triple-negative breast cancer (TNBC) subtypes. We te

Glucose-dependent insulinotropic peptide and risk of cardiovascular events and mortality : a prospective study

AIMS/HYPOTHESIS: Evidence that glucose-dependent insulinotropic peptide (GIP) and/or the GIP receptor (GIPR) are involved in cardiovascular biology is emerging. We hypothesised that GIP has untoward effects on cardiovascular biology, in contrast to glucagon-like peptide 1 (GLP-1), and therefore investigated the effects of GIP and GLP-1 concentrations on cardiovascular disease (CVD) and mortality r

The Historical Geography of Phrygia : The Settlement of Leonton Kephalai

This article examines the literary evidence for a settlement in Phrygia named Leonton Kephalai, i.e. Lions´Heads. According to preserved literary sources, of which there are only three, Leonton Kephalai was an important military stronghold from the Achaemenid period until the end of the Roman Republic, but the settlement may have been occupied for longer. Furthermore, one literary source specifial

Uncertainty and the Great Slump

This article investigates the impact of economic policy uncertainty on the British interwar economy. The first type of evidence examined is qualitative. The historical record shows that contemporaries regularly reported the incidence and consequences of major uncertainty shocks. The second type of evidence analysed is quantitative. Based on a new index of economic policy uncertainty constructed fr

Laminar burning velocities of surrogate components blended with ethanol

To provide a consistent database for all important classes of hydrocarbons considered as components of surrogate mixtures, laminar burning velocities of n-decane, p-xylene and methylcyclohexane blended with ethanol were determined using the heat flux method at atmospheric pressure and initial temperatures of 318–400 K. The results obtained at Samara University and Lund University are within overla

The 21st Century movement within the area of skin sensitization assessment : From the animal context towards current human-relevant in vitro solutions

In a regulatory context, skin sensitization hazard and risk evaluations of manufactured products and their ingredients (e.g. cosmetics) are mandatory in several regions. Great efforts have been made within the field of 21st Century Toxicology to provide non-animal testing approaches to assess the skin allergy potential of materials (e.g. chemicals, mixtures, nanomaterials, particles). Mechanistic

Alloxan cytotoxicity in vitro : Microscope photometric analyses of trypan blue uptake by pancreatic islet cells in suspension

Suspensions of islet cells were prepared by shaking pancreatic islets from non inbred ob/ob mice in a Ca 2+ free buffer. The cells were incubated with or without 20 mM alloxan, and subsequently with Trypan Blue. The uptake of Trypan Blue by cell nuclei was analysed by microscope photometry and by counting the frequency of cells appearing stained on visual inspection. Cells classified as stained o

Stimulation of insulin release by thiols

The effects of thiol compounds on insulin release were studied in microdissected pancreatic islets of non-inbred ob/ob mice. In control experiments the reactivity of thiols against 6,6′-dithiodinicotinic acid and the degradation of mouse insulin were measured. At a concentration of 0.1 mM, 1-thio-D-glucose or reduced glutathione potentiated the insulin-releasing action of 10 mM D-glucose without a

Glucagon and insulin release from the allografted canine pancreas

Six previously pancreatectomized dogs were transplanted with ductligated, pancreatic allografts. Glucagon and insulin levels in the venous outflow from the graft and in the systemic circulation were determined during the first 60 minutes after transplantation. Two of the dogs were subjected to L-arginine stimulation 5 days after transplantation and the glucagon levels in the venous outflow from th

The use of dispersed pancreatic islet cells in measurements of transmembrane transport

Suspensions of dispersed islet cells were prepared by shaking collagenaseisolated pancreatic islets of ob ob-mice in Ca2+-free buffer. The dispersed cells exhibited a glucose uptake with stereospecificity for the d isomer and concentrated Rb+ about 30-fold from a medium containing 70 μm RbCl. These results compare well with previous observations on unbroken islets and indicate that the dispersion

Cytotoxic effects of a thiol reactive ferritin compound on isolated pancreatic β cells and the protective action of L cysteine

The effects of an electron dense thiol reagent, Hg phenylazo ferritin, on β cell ultrastructure was studied in cell suspensions from mouse pancreatic islets. This type of thiol reagent induced severe damage in the β cells. The ferritin particles were traced with the electron microscope and found to be bound to the plasma membrane as well as to various cytoplasmic structures. The β cell cytotoxic a

Content of adenosine 3′:5′-cyclic monophosphate in the pancreatic islets of mice with a hereditary defect of insulin secretion

Glucose (20 mM) released insulin from pancreatic islets of C57BL 6J- db2J db2J mice, the response being potentiated by 1 mM 3-isobutyl-1-methylxanthine. Islets of C57BL KsJ- db db mice failed to respond to glucose and released only little insulin when challenged with both glucose and methylxanthine. After incubation with 0 or 20 mM glucose alone the islet content of adenosine 3′:5′-cyclic monophos

Growth, Factor Shares, and Factor Prices

This dissertation is a study in empirical macroeconomic history. The first two papers concern themselves with the functional distribution of income. The third paper is an examination of global real interest rates, and the final paper examines city growth in Sweden over the last two hundred years. While this thesis is not about secular stagnation per se, every articles is related in one way or the

New Guidelines for AOM Treatment in Sweden

In October 2010 new recommendations were issued in Sweden concerningthe treatment of acute otitis media (AOM). Watchful waiting is recommendedfor otherwise healthy children aged 1-12 years with uncomplicated AOM. In allpatients with complicating circumstances and all patients under the age of 1 yearand over the age of 12 years (including adults) antibiotic treatment of AOM isrecommended. In the gu
