The diagnosis chylothorax is based on a chemical analysis of the pleural effusion. According to the literature, this analysis can be rather straightforward, comprising measurements of triglycerides, chylomicrons, and cholesterol. In this report we present an autopsy case that alerted us to interpret these results critically. Although the laboratory tests of the pleural effusion in this patient ...

The novel group of amphotericin B (AmB) cationic derivatives has been examined in terms of relationship between self-association and selective toxicity. In all determinations AmB has been used as reference compound. In vitro toxic effects of the compounds on human erythrocytes were determined by measuring leakage of intracellular potassium ions and hemolysis. Antifungal effects were determined ...

OBJECTIVE To investigate the changes including expression and localization of 2 potassium channels, renal outer medullary K+ channel (ROMK) and voltage-gated K+ channel 7.1 (KCNQ1), after increased urinary potassium leakage in patients with interstitial cystitis/painful bladder syndrome (IC/PBS). MATERIALS AND METHODS The study group included 24 patients with IC/PBS and a control group consis...

The aim of this work was to evaluate how an aqueous micellar system containing Amphotericin B (AmB) and sodium deoxycholate (DOC) can be rebuilt after heating treatment. Also, a review of the literature on the physicochemical and biological properties of this new system was conducted. Heated (AmB-DOC-H) and unheated (AmB-DOC) micelles were then diluted at four different concentrations (50 mg · ...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...

The effect of feedback inhibition from thalamic reticular cells on retinogeniculate transmission by thalamocortical neurons of the dorsal lateral geniculate nucleus is analyzed using a minimal integrate-and-fire-or-burst network model. Potassium leakage conductances control the neuromodulatory state of the network and eliminate rhythmic bursting in the presence of spontaneous input. During osci...

In the last years, there is a growing demand for plants used in traditional medicine. Licorice (Glycyrrhiza glabra) contains different phytocompounds, that have demonstrated various pharmacological activities. The endophytic fungus, Piriformospora indica, has been reported to enhance the growth of host plants and allow them to survive under abiotic and biotic stress. This study was undertaken t...

In a series of experiments performed on intact cells or spheroplasts of E. coli and Bac. subtilis a possibility of non-thermal effects induced by continuous microwave irradiation of a low power density (at wave length range from 0.0 to 7.8 mm) was studied. Thymidine and thymine uptake, leakage of potassium and hydrogen ions as well as the uptake of the transforming DNA by the component cells of...

introduction: the provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. root-end resection, preparation and obturation should provide an adequate apical seal. the aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of thes...
