INTRODUCTION: The role of IgA receptors in dermatitis herpetiformis (DH) pathogenesis is still unknown. CD89 and CD71 may be associated with immune response during DH development. The purpose of this study was to perform semiquantitative analysis of simultaneous immunoexpression of CD89 and CD71 in DH and IgA/neutrophil-mediated non-DH dermatoses (IgAN) in relation to specific IgA autoantibodies/antibodies (tissue and epidermal transglutaminases, nonapeptides of gliadin - eTG/tTG/npG) as well neutrophil activation via the release of neutrophil elastase (NE)...

INTRODUCTION: Significant and accessible predictive factors for bortezomib treatment in plasma cell myeloma (PCM) are still lacking. TP53 codon 72 polymorphism (P72R) results in proline (P) or arginine (R) at 72 amino acid position, which causes synthesis of proteins with distinct functions. The aims of our study were to: 1) analyze whether this polymorphism is associated with an increased risk of PCM; 2) study whether the P72R polymorphism affects overall survival (OS) among PCM patients; 3) assess the possible association of the P72R polymorphism with sensitivity to bortezomib in cell cultures derived from PCM patients...

INTRODUCTION: Greater splanchnic nerve (GSN) is by far the largest of the splanchnic nerves and connects the paravertebral and prevertebral ganglia to transmit the majority of nociceptive information from the viscera. Despite its importance, the immunohistochemical features of the porcine GSN neurons have not yet been examined. Therefore, the aim of the study was to investigate the neurochemistry of the porcine GSN neurons and to compare their neurochemical coding with those of the paravertebral and prevertebral ganglia...

INTRODUCTION: Sirtuins are NAD dependent class III histone deacetylases. In adrenal cortex mitochondria are able to transform - via nicotinamide nucleotide transhydrogenase (NNT) - NAD into NADPH, which is required for steroidogenesis. These findings suggest that sirtuins expressed in mitochondria, Sirt3, Sirt4 and Sirt5, may be associated with adrenal steroidogenesis. Therefore, the purpose of this study was to characterize the expression of mitochondrial sirtuins (Sirt3-5) in individual compartments of rat adrenal cortex, their developmental regulation and to demonstrate whether their expression is dependent on adrenocorticotrophic hormone (ACTH) and Nampt (nicotinamide phosphoribosyltransferase also known as visfatin/PBEF), the rate-limiting enzyme in the regulation of mammalian NAD synthesis...

INTRODUCTION: Endometritis and endometrosis have been and still are the major reasons for infertility in mares. The diagnosis of endometritis can be based on cytology and microbiology, but endometrial biopsy is still the only way to diagnose endometrosis in the mare. Our study attempted to determine if a single biopsy using histopathology and immunohistochemistry is sufficient to ascertain reasons for infertility in Icelandic mares. The objectives of this study were to examine the relationship between deviations in endometrial biopsies in terms of prostaglandin-endoperoxide synthase-2 (PTGS-2) and fibronectin expression and polymorphonuclear cells (PMNs) infiltration, as well as scoring degeneration in two endometrial biopsies...

Cytogenetic lesions do not completely explain clinical heterogeneity of chronic lymphocytic leukemia (CLL). The 2016 revision of the World Health Organization classification 2008 introduced that molecular lesions of TP53, NOTCH1, SF3B1 and BIRC3 have potential clinical relevance and could be integrated into an updated risk profile. The negative clinical implications of TP53 disruptions are well constituted and patients with these mutations should be considered for novel, small molecule signal transduction inhibitors therapies...

Circulating tumor cells (CTC) represent a very small subpopulation of the cancer cells found in the bloodstream of patients in the metastatic phase of neoplastic disease. Due to the timeline of the disease, they are regarded as a negative prognostic marker. This study focused on determining CTC percentages; these values vary between different types of cancer. In addition to their diagnostic use, CTCs may also be used to treat the disease. Calculating CTC population size and analyzing their biology in patients in advanced stages of cancer may prove valuable in creating a molecular profile for the disease...

INTRODUCTION: Factors promoting nerve cell ingrowth are considered responsible for chronic back pain resulting from the intervertebral disc degeneration (IDD). One of the recent exploratory IDD treatments is stem cell transplantation therapy. The CD271 (low-affinity nerve growth factor receptor) has been identified as a marker of the most homogeneous mesenchymal stem cell (MSC) subset. It is capable of promoting differentiation along adipogenic, osteogenic and chondrogenic lineages and producing significantly higher levels of cytokines as compared to the total population of plastic adherence-mesenchymal stem cells (PA-MSCs)...

INTRODUCTION: . In traditional medicine, Citrullus colocynthis is used to treat diabetes, hyperlipidemia, cardiovascular diseases, inflammation, and oxidative stress, all of which can appear when a diet rich in vegetable fats, such as palm oil, is continuously consumed. Such high-fat diets are chronic stressors of the hypothalamic-pituitary-adrenal axis. The objective of our study was to analyze and evaluate the effects of colocynth total alkaloids and glycosides on metabolic, hormonal, and structural disorders of the adrenal medulla in Wistar rats fed a high-fat diet...

INTRODUCTION: Elevated plasma homocysteine (Hcy) levels have been associated with several tissue injuries including heart and liver fibrosis. In these diseases, hyperhomocysteinemia (Hhcy) plays a major role in modulating the alteration of the balance between matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMPs), leading to the pathological accumulation of extracellular matrix (ECM) proteins. Since the effect of Hhcy on ECM of seminal vesicle was not studied, the aim of our research was to check if Hcy can induce a remodeling within seminal vesicles ECM...

INTRODUCTION: Much of what we know about the functioning of human T lymphocytes is based on the experiments carried out in atmospheric oxygen (O₂) concentrations, which are significantly higher than those maintained in blood. Interestingly, the gender differences in the activity of T cells and their susceptibility to apoptosis under different O₂ conditions have not yet been described. The aim of the study was to compare two main markers of lymphocyte function: proliferation capacity and ability to produce cytokines as well as their susceptibility to apoptosis under two different O₂ concentrations, between men and women...
