Mechanisms of herb-induced nephrotoxicity.
2013
Herbal therapies gained much popularity among the general public, but compared to therapies approved by official authorities, toxicological studies are frequently not available for them. Hence, there may be inherent risks and the kidneys may be especially vulnerable to toxic effects. Herbs may induce nephrotoxicity by induction of apoptosis. High oxalate contents in Star fruit (Averrhoa carambola L.) may induce acute nephropathy. Triptolide from Thunder God Vine (Triperygium wilfordii Hook) is a diterpenoid epoxide with induces reactive oxygen species and nephrotubular apoptosis. Cranberry juice is discussed as promoter of kidney stone formation (nephrolithiasis). Abuse of guaifenesin from …
The Formation of a Collective Identity Through Expressions of ‘Love’ and ‘Hate’: An Exploratory Analysis of the Discourse of Football Fans in Germany…
2021
International audience; Football is an exemplary platform where the social dynamics within and between societies can be regularly observed. In addition, online message boards are a rich resource of everyday expressions where football fans express their ‘love’ of their clubs as well as their ‘disdain’ for others. We conducted a qualitative content analysis during two seasons of Olympique de Marseille and FC Bayern Munich as well as Toulouse FC and Hannover 96. Our analysis illustrates that hateful expressions that differentiate groups are much more prevalent and therefore more determinant in the formation of a collective identity. Furthermore, the analysis confirms that the self-conception c…
Efficient stabilisation of a dihydrogenphosphate tetramer and a dihydrogenpyrophosphate dimer by a cyclic pseudopeptide containing 1,4-disubstituted …
2017
A cyclic pseudooctapeptide 2 is described containing 1,4-disubstituted 1,2,3-triazole moieties. This compound features eight converging hydrogen bond donors along the ring, namely four amide NH and four triazole CH groups, which enable 2 to engage in interactions with anions. While fully deprotonated sulfate anions exhibit only moderate affinity for 2, protonated anions such as dihydrogenpyrophosphate and dihydrogenphosphate anions are strongly bound. Complexation of the phosphate-derived anions involves sandwiching of a dihydrogenpyrophosphate dimer or a dihydrogenphosphate tetramer between two pseudopeptide rings. X-ray crystallography provided structural information, while 1H NMR spectro…
Owrzodzenie podudzia związane z niewydolnością żyły mięśnia brzuchatego łydki - opis przypadku
2008
Przedstawiono przypadek chorego z żylnymi owrzodzeniami goleni na tle niewydolności żyły mięśnia brzuchatego łydki z układem refleksowym typu „enigma of the gastrocnemius vein”. Operacja polegała na wybiórczym podwiązaniu niewydolnego perforatora łączącego żyłę mięśnia brzuchatego łydki z żyłą odstrzałkową. Po operacji owrzodzenia wygoiły się oraz ustąpił refluks w układzie żyły mięśnia brzuchatego łydki. Omówiono również taktykę operacji u chorych z żylakami towarzyszącymi niewydolności żyły mięśnia brzuchatego łydki.
The behavior of Rare-Earth Elements, Zr and Hf during biologically-mediated deposition of silica-stromatolites and carbonate-rich microbial mats
2015
Abstract Venere Lake, in the Pantelleria Island thermal system (Central Mediterranean Sea) consists of a mix of seawater and hydrothermal volcanic fluids containing high levels of dissolved SiO 2 . Close to the lake's thermal springs, siliceous stromatolites are deposed under high bacterial activity conditions whereas roughly interlaminated Ca-carbonates and microbial mats are widely scattered in the lake. The dissolved REE speciation in lake waters is dominated by [REE(CO 3 ) 2 ] − , [REE(CO 3 )] + and [REE(H 3 SiO 4 )] 2 + complexes. On the contrary the most abundant Zr and Hf species are hydroxyl- and fluoride-complexes. The behavior of REE Zr and Hf in the Venere lake waters is controll…
Toxicity of waste dump leachates and sugar factory effluents and their impact on groundwater and surface water quality in the Opole Province in Poland
2000
A battery of Toxkit microbiotests with 4 aquatic species from different trophic levels has been used to evaluate the toxicity of 2 types of point source pollution in the Voivoidship of Opole in Poland: percolating waters from drainage systems of 4 municipal waste dumps and the effluents of a sugar factory. In addition, the toxicity of groundwaters from 2 wells near 2 waste dumps was also assessed. All the drainage waters of the waste dumps and the groundwaters near one dump (an unprotected landfill) showed toxic effects on all the test species, for samples taken in spring as well as in autumn. The well water of the (more recent) waste dump of the City of Opole in turn did not show any toxic…
Geochemistry of phosphatic nodules as a tool for understanding depositional and taphonomical settings in a paleolithic cave site (San teodoro, Sicily)
2021
Interpreting depositional settings of cave sites is generally problematic, especially in absence of palaeontological/archaeological evidence. This is the case of some deposits at San Teodoro Cave (Sicily), a key site for the Mediterranean Palaeolithic. In a stratigraphic level interrupted by a carbonatic concretion, phosphatic nodules are present only in the part enclosed between the concretion and the cave wall. The discovery of these nodules combined with the punctual lack of fossils had initially suggested an erosion phenomenon and subsequent formation of nodules at a vadose level. Here we show the usefulness of an integrated, geochemical-palaeoecological approach in defining stratigraph…
Using the Trace Element Contents in Bronchoalveolar Lavages to Probe the Human Exposure to Inhaled Particulates
2013
Explosive volcanic eruptions eject large volumes of high surface area, metal-rich dust and ash into the atmosphere. In areas near major volcanic eruptions, humans often interact with these materials and may bioaccumulate heavy and toxic metals. To evaluate these interactions, we examine bronchoalveolar lavage samples (BAL) collected from people exposed to the paroxysmal 2001 Etna eruption. BAL samples reveal a strong enrichment of many toxic heavy metals and the capacity for trace elements released from inhaled particles to induce crystallisation of phosphatic microcryst biominerals in intraaveolar spaces. BAL rare earth element (REE) concentration patterns normalised to shale reveal a ‘V-s…
L'ekkyklema nel teatro greco dell'età classica
2016
The aim of this paper is to demonstrate that the tragic poets of the fifth century BC used an engine called ekkyklema in order to reveal the scenes supposed to take place inside. I think I can indicate a passage, that clearly demonstrates the use of such an engine (Eur. Her. 1028 ff.), since the chorus' words are otherwise unintellegibile. Comic poets used this engine only for paratragic purpose, because the distinction inside/outside was not relevant for comedy.
Prolonging in utero-like oxygenation after birth diminishes oxidative stress in the lung and brain of mice pups☆
2013
Background Fetal-to-neonatal transition is associated with oxidative stress. In preterm infants, immaturity of the antioxidant system favours supplemental oxygen-derived morbidity and mortality. Objectives To assess if prolonging in utero-like oxygenation during the fetal-to-neonatal transition limits oxidative stress in the lung and brain, improving postnatal adaptation of mice pups. Material and methods Inspiratory oxygen fraction (FiO2) in pregnant mice was reduced from 21% (room air) to 14% (hypoxia) 8–12 h prior to delivery and reset to 21% 6–8 h after birth. The control group was kept at 21% during the procedure. Reduced (GSH) and oxidized (GSSG) glutathione and its precursors [γ-glut…
