The globular clusters of large spiral galaxies can be divided into two populations: one that formed in situ and one that comprises clusters tidally stripped away from other galaxies. In this paper, we investigate the contribution to the outer globular cluster population in the M31 galaxy through donation of clusters from dwarf galaxies. We test this numerically by comparing the contribution of glo

Objectives: Gastrointestinal symptoms are common in endometriosis, but the mechanisms behind these symptoms are yet poorly understood. Associations between endometriosis and irritable bowel syndrome (IBS), celiac disease, and various autoimmune diseases have been reported. These diseases express characteristic autoantibodies. The aim of the current study was to investigate autoantibodies against g

This pilot study is an attempt to explore how fundamental frequency (f0) as an acoustic correlate to paralinguistic infor- mation and biological codes are em- ployed in interspecific vocal communi- cation. Measures of f0 in human (Homo sapiens) and domestic cat (Felis catus) intra- and interspecific communication were compared. Results showed higher mean f0 in interspecific than intraspe- cific ut

Glycans at the surface of cellular membranes modulate biological activity via multivalent association with extracellular messengers. The lack of tuneable simplified models mimicking this dynamic environment complicates basic studies of these phenomena. We here present a series of mixed reversible self-assembled monolayers (rSAMs) that addresses this deficiency. Mixed rSAMs were prepared in water b

In the project Melody in Human–Cat Communication (Meowsic) we are using established phonetic methods to collect, annotate, pre-process and analyse domestic cat–human vocal communication. This article describes these methods, and also presents results of meow vocalisations in four different mental states showing variation in fundamental frequency (f0).

Background: Acute type B aortic dissection (AoD) with malperfusion is a rare and complex disease. In this specific setting, invasive treatment is generally required to improve aortic branch vessel flow. Thoracic aorta stent grafting (TEVAR) of the proximal descending thoracic aorta to cover/exclude the proximal intimal entry tear would promote resolution of the dynamic component (the most prevalen

Objective: Hepatocellular carcinoma (HCC) is one of the most common malignant tumors with high mortality-to-incidence ratios. Apolipoprotein M (ApoM), a member of the apolipoprotein family, is mainly synthesized in the liver, whereas its role in HCC has not been elucidated. Here, we examined the effect of ApoM on the biological behavior of HCC cells and the possible mechanisms. Methods: We used CR

The lymphopenia gene (lyp) on rat chromosome 4 is closely linked to autoimmune diabetes in the BioBreeding (BB) rat. Lyp controls the number of peripheral lymphocytes by reducing T cells of the RT6+ phenotype by almost 90%. Following nine cycles of marker-assisted cross-intercross breeding we have developed congenic lyp/lyp, lyp/+ and +/+ (wildtype) rats on the background of DR rats. Prediabetic a

OBJECTIVE - To analyze the effect of antibodies to glutamic acid decarboxylase (GAD65Ab) and islet cells (ICA512Ab) on glycemic control early in IDDM. RESEARCH DESIGN AND METHODS - GAD65Ab and ICA512Ab were measured twice in 35 patients (10 male, 25 female; age 1040 years) initially within 2 years of diagnosis and again 1 year later. The glycosylated hemoglobin was measured one to four times each

Dolinina J, Rippe A, Öberg CM. Sustained, delayed, and small increments in glomerular permeability to macromolecules during systemic ET-1 infusion mediated via the ETA receptor. Am J Physiol Renal Physiol 316: F1173–F1179, 2019. First published March 13, 2019; doi:10.1152/ajprenal.00040.2019.—Emerging evidence indicates that endogenous production of endothelin (ET)-1, a 21-amino acid peptide vasoc

Glucokinase plays an important role in the regulation of insulin secretion and is therefore an attractive candidate gene for both insulin dependent (IDDM) and non-insulin-dependent (NIDDM) diabetes mellitus. A single G-A nucleotide polymorphism at the -30 position of the beta-cell specific promoter region of the glucokinase gene was previously associated with reduced beta-cell function. In the pre

OBJECTIVE - To investigate the association of GAD (65-kDa) autoantibodies (GAD65-Abs) and IA-2 autoantibodies (IA-2-Abs) with human leukocyte antigen (HLA)-DQ and insulin gene (INS) risk markers in patients with recent-onset IDDM and their siblings. RESEARCH DESIGN AND METHODS - Blood was sampled from 608 recent-onset IDDM patients and 480 siblings, aged 0-39 years and consecutively recruited by t

Most IDDM patients temporarily restore some of their beta-cell function following the initiation of insulin therapy. The aim of this study was to analyse the influence of age, gender, metabolic state at diagnosis and presence of autoantibodies (GAD65 antibodies and ICA) on the duration of the clinical partial remission. In total, 149 consecutively diagnosed IDDM children, 0-16 y old (70F, 79M, mea

Autoantibodies to glutamic acid decarboxylase (GAD65Ab) are common in both caucasian and Japanese patients with insulin-dependent diabetes mellitus (type 1), while the type 1-associated HLA haplotypes differ. In the present study, we analyzed GAD65Ab in relation to HLA-DQ and -DR alleles in Japanese type 1 patients. GAD65Ab were found in 58% short-duration (less than 5 years) type 1, 23% long-dura

Two large population-based case-control studies are reviewed. The aim is to determine the effects of HLA, other genetic factors and immune markers (ICA, IAA and GAD65Ab) on the age at onset of insulin-dependent diabetes mellitus (IDDM) in 0-34 year olds. The primary HLA risk gene sequence for IDDM was difficult to identify because of the low recombination frequency within the HLA region. The frequ
