Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes, involved in the degradation of extracellular matrix components. The physiological function of MMP-9 is associated with regulation of immune processes, embryogenesis, reproduction and wound healing. MMP-9 also plays a critical role in tumor invasion, degrading the basement membrane, what is observed in different types of cancers: breast, gastrointestinal, and gynecological. AIM: The aim of this study was to investigate the plasma levels and diagnostic utility of MMP-9 and CA 125 in cervical cancer patients...

Despite progress in the development of novel pharmacological compounds, their efficacy in the treatment of neuropathologies is not satisfactory. One strategy to achieve safe and efficient brain targeting therapy is to design nanocarriers capable of transporting antipsychotic drugs through the BBB (without affecting the normal functions of the barrier) in a defined part of the brain. Here we investigate the interaction of clozapine-loaded polymeric Nano capsules (CLO-NCs) with hCMEC/D3 (human cerebral microvascular endothelial cells, D3 clone) cells that constitutes an in vitro model of the blood brain barrier (BBB)...

Chronic kidney disease (CKD) results in decreased bone strength. Serotonin (5-HT) is one of the critical regulators of bone health, fulfilling distinct functions depending on its synthesis site: brain-derived serotonin (BDS) favors osteoblast proliferation, whereas gut-derived serotonin (GDS) inhibits it. We assessed the role of BDS and peripheral leptin in the regulation of bone metabolism and strength in young rats with 5/6 nephrectomy. BDS synthesis was accelerated during CKD progression. Decreased peripheral leptin in CKD rats was inversely related to BDS content in the hypothalamus, brainstem and frontal cortex...

BACKGROUND: Acceptance of illness is a significant determinant of further coping with a disease. Development of illness acceptance may be associated with the sense of coherence and perception of social support. Cancer is an example of a crisis situation which affects both the patient and his/her close relatives. Consequently, acceptance of illness may be influenced by factors originating from both sides of caregiver-patient dyad. The aim of this study was to analyze direct and indirect interrelationships between perceived support and the sense of coherence (SOC) in patient-caregiver dyad, and acceptance of illness in cancer patients...

Cell-based therapies that could provide an alternative treatment for the end-stage liver disease require an adequate source of functional hepatocytes. There is little scientific evidence for the influence of patient's age, sex, and chemotherapy on the cell isolation efficiency and metabolic activity of the harvested hepatocytes. The purpose of this study was to investigate whether hepatocytes derived from different sources display differential viability and biosynthetic capacity. Liver cells were isolated from 41 different human tissue specimens...

Urease is an important virulence factor from Helicobacter pylori that enables bacterial colonization of human gastric mucosa. Specific inhibition of urease activity can be regarded as a promising adjuvant strategy for eradication of this pathogen. A group of organophosphorus inhibitors of urease, namely, aminophosphinic acid and aminophosphonic acid derivatives, were evaluated in vitro against H. pylori urease. The kinetic characteristics of recombinant enzyme activity demonstrated a competitive reversible mode of inhibition with Ki values ranging from 0...

Differentiation between the sialyl linkages is often critical to understanding biological consequence. Here we present a facile method for determining these linkages in glycans. Analysis of sialic acids is challenging due to their labile nature during sample preparation and ionization. Derivatization is often required via chemical reaction. Amidation derivatizes all sialic acids regardless of linkage, while esterification enables differentiation between α2,3-linked and α2,6-linked sialic acids. Reactions have been primarily performed on free glycans in solution but have been recently adapted to solid-phase providing unique advantages such as simplified sample preparation, improved yield, and high throughput applications...

Pulmonary arterial hypertension is a disease that has a bad influence on the patient's prognosis. Recently, the possibility of therapy has dramatically changed. Nowadays, the treatment of this disease is concerned mainly with the pathophysiological target. In clinical practice, it is important to start therapy at the appropriate time, when the patient is qualified because of an unsatisfactory examination result or improve therapy when the patient is getting worse. The understanding of prognosis factors in pulmonary arterial hypertension is necessary, because it is used to determine the length of patients' life expectancy...

Vitreoretinal interface pathologies, such as vitreomacular traction syndrome, epiretinal membranes and macular holes are sight-threatening conditions and one of the important causes of vision defects and vision loss. To this date, vigilance with observation of how the vitreomacular traction resolves, or vitreoretinal surgery in more severe cases, were the only treatment options. Recent rapid progress in ophthalmology, especially in diagnostic and visualization techniques, provided better insight into the mechanisms taking place on the vitreoretinal surface, which enabled a more accurate selection of treatment options...
