Opis:: Arsenic is a worldwide environmental pollutant that generates public health concerns. Various types of cancers and other diseases, including neurological disorders, have been associated with human consumption of arsenic in drinking water. At the molecular level, arsenic and its metabolites have the capacity to provoke genome instability, causing altered expression of genes. One such target of arsenic is the Pax6 gene that encodes a transcription factor in neuronal cells. The aim of this study was to evaluate the effect of two antioxidants, α-tocopheryl succinate (α-TOS) and sodium selenite, on Pax6 gene expression levels in the forebrain and cerebellum of Golden Syrian hamsters chronically exposed to arsenic in drinking water. Animals were divided into six groups. Using quantitative real-time reverse transcriptase (RT)-PCR analysis, we confirmed that arsenic downregulates Pax6 expression in nervous tissues by 53 ± 21% and 32 ± 7% in the forebrain and cerebellum, respectively. In the presence of arsenic, treatment with α-TOS did not modify Pax6 expression in nervous tissues; however, sodium selenite completely restored Pax6 expression in the arsenic-exposed hamster forebrain, but not the cerebellum. Although our results suggest the use of selenite to restore the expression of a neuronal gene in arsenic-exposed animals, its use and efficacy in the human population require further studies.

Tytuł:: The largest giant gypsum intergrowths from the Badenian (Middle Miocene) evaporites of the Carpathian Foredeep

Opis:: The Badenian (Middle Miocene) evaporite deposits of the Carpathian Foredeep in Poland, Ukraine and Czech Republic, contain large bottom-grown primary gypsum crystals (selenite) which are some of the largest in the world. The 0.5-3.5 m long crystals are arranged in a palisade manner and create specific intergrowths similar to the contact swallow-tail {101} twins known in other areas. They occur in one stratigraphical interval that is several metres thick. The largest specimens were found near Busko in Southern Poland. The selenite crystals are commonly 1-1.5 m long, but specimens exceeding 2.5 m in length are present but are rare and poorly documented. Some years ago one specimen approaching 3.5 m in length was recognized at Bogucice-Skałki and seems to be the largest known and existing mineral crystal in Poland. Recently another ca. 3.5 m long selenite specimen was exposed at nearby Gacki. Both these crystals are partly damaged, and one is not fully exposed, and therefore it is difficult to establish which is (or was) actually the largest one.

Tytuł:: Mitochondrial respiratory chain inhibitors modulate the metal-induced inner mitochondrial membrane permeabilization

Opis:: To elucidate the molecular mechanisms of the protective action of stigmatellin (an inhibitor of complex III of mitochondrial electron transport chain, mtETC) against the heavy metal-induced cytotoxicity, we tested its effectiveness against mitochondrial membrane permeabilization produced by heavy metal ions Cd2+, Hg2+, Cu2+ and Zn2+, as well as by Ca2+ (in the presence of Pi) or Se (in form of Na2SeO3) using isolated rat liver mitochondria. It was shown that stigmatellin modulated mitochondrial swelling produced by these metals/metalloids in the isotonic sucrose medium in the presence of ascorbate plus tetramethyl-p-phenylenediamine (complex IV substrates added for energization of the mitochondria). It was found that stigmatellin and other mtETC inhibitors enhanced the mitochondrial swelling induced by selenite. However, in the same medium, all the mtETC inhibitors tested as well as cyclosporin A and bongkrekic acid did not significantly affect Cu2+-induced swelling. In contrast, the high-amplitude swelling produced by Cd2+, Hg2+, Zn2+, or Ca2+ plus Pi was significantly depressed by these inhibitors. Significant differences in the action of these metals/metalloids on the redox status of pyridine nucleotides, transmembrane potential and mitochondrial respiration were also observed. In the light of these results as well as the data from the recent literature, our hypothesis on a possible involvement of the respiratory supercomplex, formed by complex I (P-site) and complex III (S-site) in the mitochondrial permeabilization mediated by the mitochondrial transition pore, is updated.
