Authors: Wu YH, Lin JC, Wang TY, Lin TJ, Yen MC, Liu YH, Wu PL, Chen FW, Shih YL, Yeh IJ Abstract Hexavalent chromium [Cr(VI)], is a well‑known toxic form of the heavy metal chromium in the natural environment. Clinical evidence has indicated that exposure to Cr(VI) can cause severe renal damage. The production of reactive oxygen species (ROS) due to intracellular reduction of Cr(VI) is the main mechanism underlying the induction of cellular dysfunction and apoptosis. The present study aimed to investigate in detail the apoptotic pathways induced by Cr(VI)‑exposure in a human immortalized proximal tubular epith...

Authors: Orsini D Abstract Poverty, high population density and unhealthy dwellings in Siena's historic district accounted for the spread of tuberculosis in its various forms between the mid-nineteenth century and the first three decades of the twentieth century. In this paper, the author relies on statistical data relating to a time span between 1898 and 1935 to discuss the high incidence of scrofula, or tuberculosis of the lymphatic glands, among Siena's infant population.The result is a description of the most important actions implemented at city level to prevent tuberculosis and to assist and treat sick childr...

An excess Gibbs energy model has been proposed for modelling of aqueous two-phase systems (ATPS) containing light straight/branched alcohol, K2HPO4, and water. The hybrid ion-interaction and solvation model (HIS) was implemente...

SonawaneAbstractHerein, we report a raspberry-shaped reduced graphene oxide labelled Fe-CeO2 ternary photocatalyst synthesized via simple hydrothermal method. In order to evaluate structural, morphological, elemental composition and optical properties, resultant photocatalysts were characterized by x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), energy dispersive x-ray analysis (EDX), photoluminescence (PL) and UV-visible spectrosc...

We describe in the article effective stabilizers of model unstructured soil, sand, “polyelectrolyte complexes” (PECs), composed of two oppositely charged ionic polymers (polyelectrolytes), cationic poly(diallyldimethylammonium chloride) (PDADMAC) and anionic potassium humates (PH). By varying the PDADMAC-to-PH ratio, the total charge of PECs and their solubility in water was adjusted. The PECs as well as PDADMAC and PH were deposited on the surface of monomineral quartz sand, with a mean diameter of particles from 0.15 up to 2.1 mm. After drying, polymer-sand crusts were formed; their mechanical strength...

Written by Pendell MeyersA patient in her 50s presented with shortness of breath and fatigue worsening over 1 week. Her vital signs were within normal limits except for bradycardia at 55 bpm.Here is her ECG recorded at triage:What do you think?It is probably sinus bradycardia with very small/depressed P-waves and prolonged PR interval. The QRS is about 150 ms, and has morphology consistent with LAFB. The T-waves are peaked. All findings are concerning for hyperkalemia. Here was the baseline ECG on file:The hyperkalemia was not yet identified, and the chemistry was pending.To us, this is clearly hyperkalemia, and we on...

Louch, Erik ØieBackgroundThe optimal antiarrhythmic management of recent-onset atrial fibrillation (ROAF) or atrial flutter is controversial and there is a considerable variability in clinical treatment strategies. It is not known if potassium infusion has the potential to convert ROAF or atrial flutter to sinus rhythm (SR). Therefore, we aimed to investigate if patients with ROAF or atrial flutter and plasma-potassium levels ≤4.0 mmol/L have increase...
