A natural chabazite-based silver nanocomposite (AgMC) was synthesized to capture mercury from flue gases of coal-fired power plants. Silver nanoparticles were engineered on zeolite through ion-exchange sodium ions with ions, followed by thermal annealing. Mercury sorption test using AgMC performed at various temperatures exposing it either pulse injection or continuous flow. complete achieved up a temperature 250 °C. Nano particles shown be the main active component for amalgamation...
E-cadherin and the retinoblastoma tumor suppressor (Rb) are traditionally associated with diverse regulatory aspects of cell growth differentiation. However, we have discovered new evidence, which suggests that these proteins functionally linked in a physiologic pathway required for survival programmed death. Pharmacological activation protein kinase C (PKC) or inducible overexpression α isozyme PKC (PKCα) resulted approximately 60% apoptosis mammary prostate epithelial cells. Interestingly,...
Abstract Zeolite molecular sieves are essential to many processes in adsorption, catalysis and ion exchange. From the separation of air, petroleum cracking, water softening decontamination, these materials influence our everyday lives. Some researchers have come believe that all great discoveries field may be past. Nothing could farther from truth. new mechanisms for pore size control, nanocomposite materials, approaching dream robust, industrial‐scale sieving membranes, whole definitions...
Objective: Because of their beneficial effects in patients with hemorrhagic shock and multiple-system trauma, hypertonic saline solutions are increasingly being used perioperatively for volume resuscitation. Although the anti-edema on brain well documented a variety injury paradigms, its water content other organs has not been studied rigorously. In this study, we tested hypothesis that a) when given as an intravenous bolus continuous infusion attenuates small bowel, lung, rats without...
Titanium silicate molecular sieves contain structural units that are fundamentally different from classical aluminosilicates. In addition to ordered octahedral titanium chains, members of the zorite family pentagonal which project into main adsorption channels framework. We report effective pore size these materials can be controlled by substituting halogens at O7 sites cap pyramids projecting channel. The quantity and type halogen used determines adsorptive properties sieve. Barium exchange...
Abstract Background: Mannitol and hypertonic saline (HS) are used by clinicians to reduce brain water intracranial pressure have been evaluated in a variety of experimental clinical protocols. Administering equivolume, equiosmolar solutions healthy animals could help produce fundamental data on translocation uninjured tissue. Furthermore, the role furosemide as an adjunct osmotherapy remains unclear. Methods: Two hundred twenty isoflurane-anesthetized rats were assigned randomly receive...
Subclinical pulmonary tuberculosis (PTB) is a recently described intermediate state of great interest, but about which little known. This study sought to describe and compare the frequency key radiologic features subclinical PTB on chest radiograph (CXR) versus computed tomographic scan (CT), interpret clinical public health relevance differences. Diagnostic CXRs CT scans thorax neck in 16-year cohort patients Canada were re-acquired read by two independent readers arbitrated third reader....
Objective The purpose of this study was to analyze the incidence infections in patients following placement External Ventricular Drain (EVD) either Emergency Room (ER) or Intensive Care Unit (ICU)/ Operating (OR) at a single Comprehensive Stroke Center. Methods Retrospective analysis post-procedure infection rates 710 with EVDs placed on site between 2010 and 2018 performed. We analyzed cases sex, age, stroke non-stroke related further requirement conversion EVD ventriculoperitoneal (VP)...
Silver exchanged molecular sieves ETS-10 (Ag-ETS-10) and mordenite (Ag-mordenite) were dehydrated under vacuum at temperatures between 100 degrees C-350 C. Changes in the state of silver studied using X-ray photoelectron spectroscopy (XPS). cations titanosilicate Ag-ETS-10 are fully reduced to Ag(0) as low 150 The characteristic features XPS spectrum this species correspond only metallic silver. signal for is not observed aluminosilicate Ag-mordenite, indicating that reduced, even after heating 350
Titanium based molecular sieves, such as ETS-10, have the ability to exchange silver ions and subsequently support self assembly of stable nanoparticles when heated. We report that a high surface area sodium titanate (resembling ETS-2) displays similar template on its surface. Scanning electron microscopy (SEM) transmission (TEM) show concentrations this titanate, formed by thermal reduction exchanged cations. The range in size from 4 12 nm, centered at around 6 nm. In addition SEM TEM, XRD...
Surface templated and supported silver nanoparticles form on silver-exchanged mineral chabazite upon thermal reduction. The method generates high concentrations of thermostable, uniform nanoparticulates that may have applications as catalysts. Properties such are expected to vary with particle size, composition, metallic character, defect type density. We establish these metallic, crystalline highly twinned. twinned nature the particles influence both their remarkable stability enhanced...
