Psoriasis and psoriatic arthritis (PsA) are chronic autoimmune diseases characterized by persistent inflammation and oxidative imbalance. Oxidative stress, caused by excessive production of reactive oxygen species (ROS) and dysfunction in antioxidant mechanisms, plays a critical role in the pathogenesis of both conditions, leading to increased inflammatory processes and tissue damage. This study aims to review current antioxidant-based therapeutic options and analyze oxidative stress biomarkers in the context of psoriasis and PsA.

Exposure to heavy metals and lifestyle factors like smoking contribute to the production of free oxygen radicals. This fact, combined with a lowered total antioxidant status, can induce even more damage in the development of ankylosing spondylitis (AS). Despite the fact that some researchers are looking for more genetic factors underlying AS, most studies focus on polymorphisms within the genes encoding the human leukocyte antigen (HLA) system.

Glucocorticoids (GCs), which are secreted by the adrenal cortex, are important regulators in the metabolism of carbohydrates, lipids, and proteins. For the proper functioning of the body, strict control of their release is necessary, as increased GCs levels may contribute to the development of obesity, type 2 diabetes mellitus, hypertension, cardiovascular diseases, and other pathological conditions contributing to the development of metabolic syndrome. 11β-hydroxysteroid dehydrogenase type I (11β-HSD1) locally controls the availability of the active glucocorticoid, namely cortisol and corticosterone, for the glucocorticoid receptor.

Introduction: Difficult healing of chronic wounds is a serious problem for modern medicine. It leads to ulceration, especially in conditions such as diabetic foot syndrome or chronic venous insufficiency. This may be a result of chemical, physical, thermal or biological factors, among others.

A common mechanism in which glucocorticoids participate is suggested in the pathogenesis of such metabolic diseases as obesity, metabolic syndrome, or Cushing's syndrome. The enzyme involved in the control of the availability of cortisol, the active form of the glucocorticoid for the glucocorticoid receptor, is 11β-HSD1. Inhibition of 11β-HSD1 activity may bring beneficial results for the alleviation of the course of metabolic diseases such as metabolic syndrome, Cushing's syndrome or type 2 diabetes.

Tumors are currently more and more common all over the world; hence, attempts are being made to explain the biochemical processes underlying their development. The search for new therapeutic pathways, with particular emphasis on enzymatic activity and its modulation regulating the level of glucocorticosteroids, may contribute to the development and implementation of new therapeutic options in the treatment process. Our research focuses on understanding the role of 11β-HSD1 and 11β-HSD2 as factors involved in the differentiation and proliferation of neoplastic cells.

Glucocorticoid metabolism at the tissue level is regulated by two isoenzymes 11β-hydroxysteroid dehydrogenase (11β-HSD), which mutually convert biologically active cortisol and inactive cortisone. Recent research is focused on the role of 11β-HSD1 and 11β-HSD2 as autocrine factors of tumor cell proliferation and differentiation. Herein, we report the synthesis of novel 2-(isopropylamino)thiazol-4(5)-one derivatives and their inhibitory activity for 11β-HSD1 and 11β-HSD2.

Objectives: Obesity has serious consequences such as the onset of metabolic syndrome, type 2 diabetes, atherosclerosis, or cardiovascular complications. The aim of this study was to evaluate the levels of paraoxonase 1 (PON1), lectin-like oxidized LDL receptor-1 (LOX-1), antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx)), and lipid peroxidation processes in the course of obesity.

Methods: 28 men took part in the experiment.

The metabolic syndrome is defined by impaired carbohydrate metabolism and lipid disorders and often accompanied by hypertension, all of which will lead to obesity and insulin resistance. Glucocorticoids play a regulatory role in the metabolism of proteins, lipids, and carbohydrates. There is growing evidence for a role of glucocorticoids in the development of the metabolic syndrome.

Article Synopsis
  • Tinnitus is characterized as hearing sounds that aren't present in the environment, and this study aimed to evaluate the antioxidant defenses in tinnitus patients.
  • The research involved 51 tinnitus patients and 19 healthy controls, where various auditory tests and blood analyses were conducted to measure oxidative stress markers.
  • Results indicated that tinnitus patients had a reduced effectiveness of their natural antioxidant defenses, suggesting a need for further research to explore potential antioxidant therapies to enhance their quality of life.

Uterine myomas represent one of the most frequently manifested benign tumors in women. They originate from smooth muscle cells of myometrium or its blood vessels. Many studies suggest that inflammation and pro-inflammatory factors may play a role in the carcinogenesis with an involvement of the transcription factor NF-kappaB which activity can be controlled by various environmental factors, including many cytokines.

The aim of the study was to determine the prevalence rate for inherited thrombophilia (IT) in patients with chronic (CVU) and recurrent venous leg ulceration. We also investigated and evaluated the severity of the clinical pattern of CVU in patients with and without IT. We examined 110 patients with CVU (the study group) and 110 healthy subjects (the control group).

The aim of the study is to present our own perioperative bridging therapy with low molecular weight heparin (LMWH) for surgical patients with thrombophilia on long-term acenokumarol therapy [oral anticoagulant (OAC)]. In some European countries, the drug used in secondary antithrombotic prophylaxis is acenokumarol. Forty-two patients with inherited thrombophilia and 21 with antiphospholipid syndrome underwent surgery.

Unlabelled: Surgery for malignant neoplasms in hemophilia patients is no different from standard procedures in the general population on condition that the normal hemostatic activity of deficient factors: VIII in hemophilia A and IX in hemophilia B in perioperative period is ensured. The aim of the study was to determine the type and frequency of malignant neoplasms in hemophilia patients as well as to provide a strategy for establishing safe hemostatic activity in surgically treated hemophilia patients.

Material And Methods: In the period 2003-2008, surgical procedures were performed on 19 hemophilia A and B patients with diagnosed malignant neoplasms of various location.

Background: The immediate effect of acute haemorrhage is a significant reduction in tissue blood flow, frequently resulting in haemorrhagic shock. The main aim of resuscitation after bleeding is the immediate restoration of intravascular volume. Intravenous administration of volume expanders should be commenced immediately, regardless of whether they are colloids or electrolytes.

Purpose: To identify the vascular patterns found in superficial lymph nodes with histologically confirmed lymphomatous involvement and to determine their value in the sonographic diagnosis of lymphadenopathy.

Methods And Materials: The study involved the prospective classification of vascular patterns observed during power Doppler and/or color Doppler studies of superficial lymph nodes scheduled for resection. Forty patients (27 men and 13 women, aged 22-84 years; mean age: 58 years) with pathologically proven lymphoma were selected for this study (26 cervical, 13 axillary and 1 inguinal).

Napoleon Cybulski (1854-1919) was the most prominent Polish physiologist who chaired the Department of Physiology at the Faculty of Medicine of Jagiellonian University between 1885 and 1919. One of his greatest achievements was the construction of a device for precise measurements of blood movement in the vessels - the photohemotachometer, which provided a better insight into the physiology and pathophysiology of the circulatory system. In the field of endocrinology Cybulski together with Szymonowicz, found out that adrenal extracts contain biologically active substances that elevate blood pressure.
