One of the parameters affecting the leachability of heavy metals from waste is their contact time with the leachant. In this paper, the leaching behaviour of Zn, Cu, Pb and Ni was evaluated in relation to the liquid to solid ratio (L/S), which is a reflection of time after which a certain volume of water permeates the material, e.g.

Hematopoietic stem cell transplantation (HSCT) is a curative therapy for an increasing number of nonmalignant indications. Its use is restricted by severe transplant-related complications, including CMV infection; despite various prophylactic and therapeutic strategies, CMV reactivation has remarkable morbidity and mortality. The analysis included 94 children with nonmalignant disorder who underwent allogeneic HSCT in the Department of Pediatric Hematology, Oncology, and Bone Marrow Transplantation in Wrocław during years 2016-2020.

Introduction: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a treatment method for a wide range of malignant and non-malignant diseases. Infants constitute a distinct patient group, especially due to their organ immaturity and differences in drug metabolism. The present paper aims to analyse the short- and long-term outcomes after allo-HSCT in infants.

Background: The impact of maternal diet during pregnancy on the risk of allergic diseases in childhood is an increasing scientific and public health concern. We evaluated the associations of maternal type of diet and essential elements and vitamins intake during pregnancy with offspring allergic and respiratory outcomes.

Methods: The study population included 557 mother-child pairs from Polish Mother and Child Cohort (REPRO_PL).

Exposure to environmental factors, such as neurotoxic metals and micronutrients, during critical periods of development can contribute to long-term consequences in offspring's health, including neurodevelopmental outcomes. The aim of this study was to evaluate the association between simultaneous prenatal exposure to metals [lead (Pb), cadmium (Cd), mercury (Hg)] and micronutrients [selenium (Se), zinc (Zn), copper (Cu)] and neurodevelopmental outcomes in school-age children from the Polish Mother and Child Cohort (REPRO_PL). Metals and micronutrients concentrations were measured in cord blood (Pb, Cd, Se, Zn, Cu) and in maternal hair (Hg) collected during the 3rd trimester of pregnancy.

Allo-HSCT is associated with life-threatening complications. Therefore, a considerable number of patients require admission to a PICU. We evaluated the incidence and outcome of PICU admissions after allo-HSCT in children, along with the potential factors influencing PICU survival.

The paper presents the composition and properties of low-emission ternary cements: Portland multicomponent cement CEM II/C-M and multicomponent cement CEM VI. In the ternary cements, Portland clinker was replaced at the levels of 40% and 55% with a mixture of the main components such as limestone (LL), granulated blast furnace slag (S) and siliceous fly ash (V). Portland multicomponent cements CEM II/C-M and CEM VI are low-emission binders with CO emissions ranging from 340 (CEM VI) kg to 453 (CEM II/C-M) kg per Mg of cement.

Hepatic veno-occlusive disease (VOD) is a potentially fatal complication following hematopoietic stem cell transplantation (HSCT). We evaluated in prospective analysis the usefulness of the pediatric EBMT criteria for VOD diagnosis and their presumable impact on cost effectiveness and patients' outcome. Study included all 282 HSCT procedures performed in Department of Pediatric Hematology/Oncology and BMT in Wrocław between January 2016 and March 2019.

The use of mineral additives from the power and metallurgy industries in the production of building materials still raises questions about the ecological safety of such materials. These questions are particularly associated with the release of heavy metals. The article presents research related to the leaching of chromium from concretes made of Portland cement CEM I and slag cement CEM III/B (containing 75% of granulated blast furnace slag).

The paper presents the results obtained in pH leaching test and assesses the influence of pH changes and occurring processes on the release of heavy metals (Cd, Ni, Cr, Pb, Cu and Zn) from metallurgical slag in a zinc smelter. Additionally, the analysis of the potential maximum amount of element available for leaching and releasing in the batch leaching test was carried out. All the results of the leaching tests were compared with the total content of heavy metals in the material.

Introduction: Thanks to the Polish Universal Neonatal Hearing Screening Program (PUNHSP), all newborns in Poland undergo a free, screening hearing examination. Between 2006 and 2015, the average number of tested children per year was 373,477. According to the analysis of The Central Database (CDB), only 55.

Background: Acute graft-versus-host disease (aGvHD) is a potentially fatal complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Identifying its risk factors would enable the proper prophylaxis and management, which may significantly improve the general outcome of children treated with HSCT.

Objectives: The aim of this single-center, retrospective cohort study was to assess the potential risk factors for grades II-IV of aGvHD in children after the 1st allo-HSCT from an unrelated donor (UD), performed as a result of an underlying malignant disease.

The work presents the kinetic and isotherm studies of silver binding on casein, which was carried out using batch sorption technique. Moreover, the influence of light irradiation on the process was shown. In order to investigate the mechanism of metal ions sorption by casein the zero, pseudo-first order kinetics and Weber-Morris intra-particle diffusion as well as Langmuir and Freundlich isotherm models were used.

Purpose: In patients with nephrolithiasis, oxidative stress, especially lipid peroxidation is observed. Moreover, various invasive methods [including extracorporeal shock wave lithotripsy (ESWL)] for treatment of nephrolithiasis may induce not only the oxidative stress, but they may modulate hemostasis. The study was aimed to evaluate the oxidative damages of lipids and proteins in patients with nephrolithiasis (before and after ureteroscopic lithotripsy - URSL).

Phospholipases catalyze enzymatic degradation of membrane lipids. The phospholipases are divided into four major groups: A, A, C, and D by the type of ester bond which is hydrolyzed. Phospholipases A (PLA) hydrolyze membrane glycerophospholipids at sn-2 position releasing lysophospholipid and free fatty acid.

INTRODUCTION    Rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are characterized by chronic inflammatory processes mediated by proinflammatory cytokines that affect the synovial lining. Programmed death 1 (PD‑1) is a critical regulator of T‑cell activation by downregulating immune responses.  OBJECTIVES    The aim of the study was to investigate whether the expression of PD‑1 on CD4+ and CD8+ T cells differs between patients with RA and those with PsA.
