OBJECTIVE - Ketosis-prone diabetes (KPD) is an emerging, heterogeneous syndrome. A sound classification scheme for KPD is essential to guide clinical practice and pathophysiologic studies. Four schemes have been used and are based on immunologic criteria, immunologic criteria and insulin requirement, BMI, and immunologic criteria and β-cell function (Aβ classification). The aim of the present stud

Hsu–Kasami–Chien (HKC) are a class of cyclic codes that can correct either burst or random errors. This paper studies the maximum burst-correcting capability of HKC codes. A necessary and sufficient condition for a b- burst-correcting cyclic HKC code is given and simplified as a generalized one for Fire codes. An upper bound on the burstcorrecting capability of HKC codes is derived, which improves

The smaller isoform of glutamate decarboxylase (GAD65) is a major autoantigen in type 1 diabetes (TID). Its hydrophobic character requires detergent to keep the protein in solution, which complicates studies of antigen processing and presentation. In this study an attempt was made to replace detergent with human serum albumin (HSA) for in vitro antigen presentation. Different preparations of recom

OBJECTIVE - Ketosis-prone diabetes (KPD) comprises four subgroups based on the presence or absence of β-cell autoantibodies (A+ or A-) and β-cell functional reserve (β + or β-). Genetic factors could contribute to their distinctive phenotypes. Our aim was to specify the role of HLA class II alleles associated with susceptibility or resistance to autoimmune type 1 diabetes in determining KPD phenot

This dissertation focuses on how to use prototyping as a method for developing models in Management Accounting and Control Systems, a field in Business Administration. It combines three emerging theories: prototyping, Activity Based Costing (ABC) and the Balanced Scorecard (BSc). Prototyping is an alternative to the traditional systems development method. In prototyping end-users play an important

The possible importance of virus infections before the development of islet autoimmunity and then for the appearance of clinical type 1 diabetes is reviewed. There is a lack of specific data on the role of virus to induce islet autoimmunity. There is also a paucity of data to demonstrate that virus infections may contribute to an accelerated disease process resulting in clinical onset of type 1 di

OBJECTIVE - Inflammatory mediators associated with type 1 diabetes are dilute and difficult to measure in the periphery, necessitating development of more sensitive and informative biomarkers for studying diabetogenic mechanisms, assessing preonset risk, and monitoring therapeutic interventions. RESEARCH DESIGN AND METHODS - We previously utilized a novel bioassay in which human type 1 diabetes se

Rodents homozygous for autosomal leptin receptor gene mutations not only become obese, insulin resistant, and hyperleptinemic but also develop a dysregulated immune system. Using marker-assisted breeding to introgress the Koletsky rat leptin receptor mutant (lepr-/lepr-), we developed a novel congenic BBDR.lepr-/lepr- rat line to study the development of obesity and type 2 diabetes (T2D) in the Bi

Distributed algorithms for solving coupled semidefinite programs (SDPs) commonly require many iterations to converge. They also put high computational demand on the computational agents. In this paper we show that in case the coupled problem has an inherent tree structure, it is possible to devise an efficient distributed algorithm for solving such problems. The proposed algorithm relies on predic

Background: The widely expressed protein chorein fosters activation of the phosphoinositide 3 kinase (PI3K) pathway thus supporting cell survival. Loss of function mutations of the chorein encoding gene VPS13A (vacuolar protein sorting-associated protein 13A) causes chorea-acanthocytosis (ChAc), a neurodegenerative disorder paralleled by deformations of erythrocytes. In mice, genetic knockout of c

Background: Type 1 diabetes (T1D) in both humans and BioBreeding (BB) rats is an autoimmune disease that results in complete destruction of islets and insulin dependency for life. Glucagon-like peptide 1 (GLP-1) promotes β cell proliferation and neogenesis and has a potent insulinotropic effect. We hypothesized that the expression of GLP-1 before disease onset would increase islet mass, delay diab

A tandem solar cell consisting of a III-V nanowire subcell on top of a planar Si subcell is a promising candidate for next generation photovoltaics due to the potential for high efficiency. However, for success with such applications, the geometry of the system must be optimized for absorption of sunlight. Here, we consider this absorption through optics modeling. Similarly, as for a bulk dual-jun

Immunoprotection of islets using bioisolator systems permits introduction of allogeneic cells to diabetic patients without the need for immunosuppression. Using TheraCyte™ immunoisolation devices, we investigated two rat models of type 1 diabetes mellitus (T1DM), BB rats and rats made diabetic by streptozotocin (STZ) treatment. We chose to implant islets after the onset of diabetes to mimic the pr

The loss of Gimap5 (GTPase of the immune-associated protein 5) gene function is the underlying cause of lymphopenia and autoimmune diabetes in the BioBreeding (BB) rat. The in vivo function of murine gimap5 is largely unknown. We show that selective gene ablation of the mouse gimap5 gene impairs the final intrathymic maturation of CD8 and CD4 T cells and compromises the survival of postthymic CD4

The first radio frequency (RF) noise measurements on lateral nanowire metal-oxide-semiconductor field-effect transistors (MOSFETs) and a noise model are presented. We have characterized the RF noise and scattering parameters of an indium gallium arsenide (InGaAs) device. A fitted model yields extrapolated ft = 316 GHz current gain cutoff and fmax = 166 GHz maximum oscillation frequency. This devic

A measurement of the splitting scales occuring in the kt jet-clustering algorithm is presented for final states containing a Z boson. The measurement is done using 20.2 fb−1 of proton-proton collision data collected at a centre-of-mass energy of s=8 TeV by the ATLAS experiment at the LHC in 2012. The measurement is based on chargedparticle track information, which is measured with excellent precis

Obesity and type 2 diabetes (T2D) are two prevalent chronic diseases that have become a major public health concern in industrialized countries. T2D is characterized by hyperglycemia and islet beta cell dysfunction. Glucagon-like peptide 1 (GLP-1) promotes β cell proliferation and neogenesis and has a potent insulinotropic effect. Leptin receptor deficient male rats are obese and diabetic and prov

BACKGROUND - Multiple laboratory tests are used to diagnose and manage patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these tests varies substantially. APPROACH - An expert committee compiled evidence-based recommendations for the use of laboratory testing for patients with diabetes. A newsystemwas developed to grade the overall quality of the evidenc
