The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 virus (SARS-CoV-2), has triggered an enormous scientific response. Many studies have focused on understanding the entry of SARS-CoV-2 into host cell. angiotensin-converting enzyme-2 (ACE2) is recognized as receptor used to enter its target cells. Recent suggest that ACE2 gene polymorphisms might be candidates for genetic susceptibility infection. aim this study evaluate influence disease risk and severity. In...

Introduction: Due to the SARS-CoV-2 coronavirus pandemic, wearing of masks has become a common phenomenon. Most undesirable effects using protective face covering are usually related prolonged time its wearing, and adverse consequences coverings should be considered two-fold. The aim study was evaluate rate contamination three types (surgical, N95, FFP2 masks) with microorganism—aerobic bacteria, yeasts, molds—after 3 h exposure time. aimed investigate (KN95) on respiratory function...

BACKGROUND Immunosuppressive drugs such as cyclosporine A (CsA) are characterized by a narrow therapeutic range and high interindividual pharmacokinetic variations. Therefore, the effective monitoring of drug serum level is crucial for successful therapy. This variability can be caused polymorphisms in genes encoding transporters enzymes responsible biotransformation. The aim this study was to determine relationship between CYP3A4*1B MDR1 dose requirements achieve target CsA. MATERIAL AND...

Ischemia-reperfusion injury (IRI) after renal transplantation is a complex biochemical process. The first component an ischemic phase during kidney storage. second reperfusion, the main source of oxidative stress. This study aimed to analyze activity enzymes and concentrations non-enzymatic compounds involved in antioxidant defense mechanisms: glutathione (GSH), peroxidase (GPX), catalase (CAT), superoxide dismutase (SOD), reductase (GR), transferase (GST), thiobarbituric acid reactive...

In the last decade, there has been a noticeable increase in interest aesthetic and corrective surgery regardless of patient's age. Both aesthetical practical considerations are motivation for patients undergoing plastic surgery. The goal this study is to analyze dependencies between welfare, self-assessment body self-perception that qualified surgical procedures. group included 164 female patients, whom 124 filled out questionnaire before after demographic data scales such as Body Esteem...

Background: Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder (FGID), in which etiology and pathogenesis are not fully explored. There an ongoing need for more population studies adhering to new ROME IV criteria. In the current study, follows our previous investigation among participants of Woodstock Rock Festival Poland, we aimed evaluate prevalence IBS its relation age, gender, education, type. Methods: Rome criteria questionnaire was used assess abdominal...

Ischemia-reperfusion injury (IRI) occurring after renal transplantation is a complex biochemical process that can be monitored by specific biomarkers. The roles of those are not yet fully elucidated. aim this study was to analyze the concentrations endothelins (ET-1, ET-2, and ET-3), interleukin-18 (IL-18), neutrophil gelatinase-associated lipocalin (NGAL) during reperfusion human kidneys grafted from brain dead donors later transplanted. group (n = 44) analyzed according method kidney...

Background: Kidney transplantation is followed by immunosuppressive therapy involving calcineurin inhibitors (CNIs) such as cyclosporin A. However, long-term high CNIs doses can lead to vitamin D deficiency, and genetic variations influencing levels indirectly impact the necessary dosage. This study investigates of binding protein (DBP) rs2282679 CYP2R1 hydroxylase rs10741657 polymorphisms on A dosage in kidney transplant recipients. Additional polymorphisims genes that are predicted...

During the organ procurement procedure, a surgeon encounters anatomic anomalies not very often but also uncommonly. These changes may put success of transplant into question. Despite thorough diagnosis potential donor, these are diagnosed during donation. In our paper we present case kidney transplantation with duplicated ureter. The was collected from donor inferior vena cava. After transplantation, functioned immediately. Taking consideration well-being recipient, organs abnormalities...

Acid-base balance disorders are a crucial element of ischemia-reperfusion injury during organ transplantation. Hypoxia procurement and storage cause cellular homeostasis imbalance with impact on further graft function. Acidosis in preserved kidney caused by lactate accumulation may have an important role as common denominator various pathways leading to damage. Our trial sought answer questions regarding range pH alterations the before transplantation, their potential cause, how this affect...
