Malperfusions in Acute Type B Aortic Dissection—Predictors of Outcomes

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

Apolipoprotein M could inhibit growth and metastasis of SMMC7721 cells via vitamin D receptor signaling

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 (lyp) gene controls the intrathymic cytokine ratio in congenic biobreeding rats

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

Antibodies to GAD and glycemic control in recent-onset IDDM

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

Sustained, delayed, and small increments in glomerular permeability to macromolecules during systemic ET-1 infusion mediated via the ETa receptor

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

The beta cell glucokinase promoter variant is an unlikely risk factor for diabetes mellitus

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

Associations of GAD65- and IA-2-autoantibodies with genetic risk markers in new-onset IDDM patients and their siblings : The Belgian Diabetes Registry

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

Age governs gender-dependent islet cell autoreactivity and predicts the clinical course in childhood IDDM

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

HLA class II is associated with the frequency of glutamic acid decarboxylase M(r) 65,000 autoantibodies in Japanese patients with insulin dependent diabetes mellitus

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

Genetic and immunological findings in patients with newly diagnosed insulin-dependent diabetes mellitus

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

Naturally processed T cell epitopes from human glutamic acid decarboxylase identified using mice transgenic for the type 1 diabetes- associated human MHC class II allele, DRB1*0401

The identification of class II binding peptide epitopes from autoimmune disease-related antigens is an essential step in the development of antigen- specific immune modulation therapy. In the case of type 1 diabetes, T cell and B cell reactivity to the autoantigen glutamic acid decarboxylase 65 (GAD65) is associated with disease development in humans and in nonobese diabetic (NOD) mice. In this st

Association between HLA and islet cell antibodies in diabetic patients with a mitochondrial DNA mutation at base pair 3243

Islet cell antibodies (ICA), autoantibodies to glutamic acid decarboxylase (GAD) and HLA genotypes were examined in 31 patients with diabetes and a mitochondria! gene mutation located at base pair 3243 (mtDNA 3243 mutation). ICA was detected in 42 % (13/31) of these patients compared to 0 of 90 among healthy control subjects. The ICA showed a "non-restricted" pattern of staining in all 13 ICA-posi

Islet cell and glutamic acid decarboxylase antibodies in hyperthyroid patients : At diagnosis and following treatment

Objectives. To study the frequency of islet cell (ICA) and glutamic acid decarboxylase (GAD-Ab) antibodies in patients with hyperthyroidism of different types at diagnosis before treatment and in the euthyroid state following treatment. Setting. Department of Endocrinology, Malmo University Hospital, Malmo, Sweden. Subjects and design. Blood samples were collected at diagnosis from 129 hyperthyroi

HLA and glutamic acid decarboxylase in human insulin-dependent diabetes mellitus

Insulin dependent diabetes mellitus (IDDM) is linked to HLA factors on human chromosome 6 and strongly associated with the presence of autoantibodies against the glutamic acid decarboxylase isoform GAD65. These autoantibodies, GAD65Ab are detected both before and at the time of clinical diagnosis. Molecular sequencing of HLA alleles and PCR-based genotyping have improved our understanding of the l
