Thiourea (thiophen-3-yl-acetic acid) is a well established antithyroid drug used for treating hyperactivity of the thyroid gland as it blocks the conversion of thyroxine (T4) to triiodothyronine (T3) in peripheral tissues. Human exposures to thiourea include contaminated drinking water and vegetables for its extensive use in fertilizers. Chronic thiourea exposure can cause thyroid dysfunction leading to redox imbalance. However, such effects on morphological, quantitative, functional and hypothalamo-pituitary-adrenocortical axis (HPA) analysis of the adrenal gland are yet to be explored...

Pixantrone (PIX) is an anticancer drug approved for the treatment of multiple relapsed or refractory aggressive B-cell non-Hodgkin's lymphoma. It is an aza-anthracenedione synthesized to have the same anticancer activity as its predecessors, anthracyclines ( e.g. doxorubicin) and anthracenediones ( e.g . mitoxantrone), with lower cardiotoxicity. However, published data regarding its possible cardiotoxicity are scarce. Therefore, this work aimed to assess the potential cytotoxicity of PIX, at clinically relevant concentrations (0...

Safety assessment of chemicals, pharmaceuticals, food and food ingredients, cosmetics, industrial products is very crucial prior to their approval for human uses. Since the commencement of toxicity testing (about 500 years ago, since 1520), significant advances have been made with respect to the 3Rs (reduction, refinement and replacement) alternative approaches. This review is focused on the update in acute systemic toxicity testing of chemicals. Merits and demerits of these advances were also highlighted. Traditional LD50 test methods are being suspended while new methods are developed and endorsed by the regulatory body...

Ingrid Brucknerová, Michal Dubovický, Eduard Ujházy
Despite modern approaches in molecular biology and genetics, we are still not able to identify the actual cause in more than 50% of all congenital defects. One-half of the unidentified cases is referred to as "multifactorial". Detailed prenatal investigation of the fetus can discover the presence of congenital abnormality, which can worsen the process of postnatal adaptation. Retrospective analysis of newborns admitted to the Neonatal Department of Intensive Medicine (NDIM) in 2012-2016 with the aim to analyze how the process of postnatal adaptation can be changed by the presence of congenital abnormalities of lip and palate...

Parkinson's disease (PD) is a highly prevalent neurodegenerative disorder, often associated with oxidative stress-induced transcriptional changes in dopaminergic neurons. Phenolic antioxidants, oleuropein (OLE) and rutin (RUT) have attracted a great interest due to their potential to counteract oxidative protein aggregation and toxicity. This study aimed at examining the effects of OLE and RUT against 6-OHDA-induced stress response in rat pheochromocytoma cells. When differentiated PC12 cells were exposed to oxidative stress composer 6-OHDA (100 μM, 8 h), a decreased mitochondrial membrane potential (ΔΨm) was observed along with a significant loss of cell viability and apoptotic nuclear changes...

Cadmium (Cd) is a risk factor for neurodegenerative diseases. The purpose of this study was to compare the effects of meso -2,3-dimercaptosuccinic acid (DMSA) and the polyether ionophorous antibiotics monensin and salinomycin on Cd-induced neurodegenerative alterations in mice. The results show that subacute intoxication of mice with Cd (II) acetate (20 mg/kg body weight (BW) for 14 days) caused a significant accumulation of cadmium (Cd) in the brain. Treatment of Cd-exposed mice with DMSA (20 mg/kg BW for 14 days) significantly increased the Cd concentration in the brains compared to those of the Cd-treated group...

Lead (Pb) is a toxic pollutant known to cause several abnormalities related to the brain, including cognitive dysfunction, and it is ubiquitous in nature. β-amyloid peptides (AP) are crucially involved in Alzheimer's disease (AD). It has been reported that there is a connection between lead and amyloid peptides in exerting similar kinds of altered functions in the brain and long-term exposure to lead leads ultimately to increased beta amyloid formation in the brain, lethal to human brain cells. There is still a lack of information on the mechanism by which Pb affects AP formation, exerting combined toxicity in AD patients...

The effects of four food additives, namely sodium nitrite (NaNO2 ), sodium nitrate (NaNO3 ), potassium nitrite (KNO2 ), and potassium nitrate (KNO3 ), on animal development were evaluated by using Drosophila melanogster, a model organism. Adult male and female flies were allowed to breed in culture medium, each containing one of 4 concentrations, i.e .10, 20, 30 or 40 mM of the above mentioned salts. The concentration of 40 mM, NaNO2 and KNO2 completely arrested the development of the flies. Of the different concentrations of the four salts tested, exposure of flies to 30 mM NaNO2 exhibited only significant delays in the initial appearances of third instar larvae, pupae and young adults, along with huge reduction in the number of pupae and young adults compared to controls...

5-hydroxymethyl-2-furfural (5-HMF) is a thermal decomposition product of saccharides. There are two main ways for the formation of 5-HMF. First, 5-HMF is forming during Maillard reaction and second, during thermic dehydration of saccharides under acid conditions. Significant parameters of 5-HMF formation are temperature, time, pH, water activity, type of saccharide and amino acids. It is suspected that 5-HMF has genotoxic, mutagenic and carcinogenic potential. This chemical can be found in many food sources, e...
