background: infections attributed to helicobacter pylori ( h. pylori ) involve almost half of the world's population. one of the effects is auto-antibody induction and cross-reaction with numerous proteins in the body. as a result of its widespread prevalence and importance, this study evaluates the associations between h. pylori and thyroid auto-antibodies. materials and methods: this study en...

Background
 Nowadays, we can distinguish more than two types of diabetes mellitus. Due to blood glucose measurement and genetic tests, different (such as autoimmune, monogenetic, atypical) be detected. Despite the constantly updated recommendations progress diagnostic making a diagnosis may difficult.
 Case report
 A 23-year old patient was admitted Department Endocrinology due d...

Background: Autism can occur as a result of a complex interaction between environmental factors and genetic predisposition. Mercury is a neurotoxicant and it is one of the main environmental triggers for autoimmunity. The underlying pathogenic mechanism in autoimmune disorders is the formation of auto-antibodies. Brain specific autoantibodies are elevated in a subgroup of autistic children. We ...

Molecular diagnostic tools with non-invasive properties that allow detection of pathological events in Alzheimer's disease (AD) and other neurodegenerative tauopathies are essential for the development of therapeutics. Several diagnostic strategies based on the identification of biomarkers have been proposed. However, its specificity among neurodegenerative disorders is disputable as the associ...

Abstract Background: ‘Honeymoon’ period among people with type 1 diabetes mellitus (T1DM) refers to the of time (mostly less than year) which beta-cell is still able produce insulin maintain good glycemic control shortly following development diabetes. This phenomenon remained incompletely understood but previous studies showed that absence diabetic ketoacidosis (DKA) at initial presentation, s...

Post-streptococcal autoimmunity affects millions worldwide, targeting multiple organs including the heart, brain, and kidneys. To explore the post-streptococcal autoimmunity spectrum, we used western blot analyses, to screen 310 sera from healthy subjects with (33%) and without (67%) markers of recent streptococcal infections [anti-Streptolysin O (ASLO) or anti-DNAse B (ADB)]. A 58 KDa protein,...

The seasonal change of free abscisic acid (ABA) and indole-3-acetic acid (IAA) and their relationship with the cambial activity in Eucommia ulmoides trees were investigated by ABA and IAA immunolocalization using primary polyclonal and rhodamine-red fluorescing secondary antibodies, ABA and IAA quantification using high performance liquid chromatography (HPLC), and systematic monitoring of vasc...

We identified the previously unknown structures of ribosylated imidazoleacetic acids in rat, bovine, and human tissues to be imidazole-4-acetic acid-ribotide (IAA-RP) and its metabolite, imidazole-4-acetic acid-riboside. We also found that IAA-RP has physicochemical properties similar to those of an unidentified substance(s) extracted from mammalian tissues that interacts with imidazol(in)e rec...

This study was designed to determine whether natural immune responses could elicit immunoregulatory auto-antiidiotypic antibodies. Female rabbits heterozygous at the a and b Ig loci were bred to homozygous males. Offspring of one such breeding were studied for natural production of antibodies specific for the noninherited allotypes and for the production of immunoregulatory auto-antiidiotypic a...
