In this paper, a method of Micellar Enhanced Ultrafiltration (MEUF) with Hexadecyltrimethylammonium bromide (CTAB) is proposed to remove phosphate ions from treated domestic wastewaters from the reclamation station of University Campus of Toledo (Spain). This technique is able to reach phosphate rejection coefficients higher than 99% (a phosphate concentration in permeate of 1 mg/L if feed conc...
Washing is one of the common technologies in the chlorinated organic pollution site repair, surfactant adding would help washing more chlorinated organics pollution, but it also can be dissolved in eluent with the chlorinated organic together, and increase the difficulty of the eluent treatment. In this text, three surfactants, anionic surfactant (sodium dodecyl benzene sulfonate, SDBS), cation...
Clinical trials using allogeneic mesenchymal stem cells (MSCs) are ongoing for the purpose of providing therapeutic benefit for a variety of human disorders. Pertinent to their clinical use are the accessibility to sufficient quantities of these cells allowing for repetitive administration, as well as a better understanding of the specific mechanisms by which allogeneic MSCs evade host immune r...
BACKGROUND We sought to determine the safety and efficacy of Cutting Balloon therapy (CB) compared with conventional high-pressure balloon therapy (HPB) for the treatment of pulmonary artery stenosis. METHODS AND RESULTS This prospective, randomized, multicenter, investigational device exemption trial compared CB with HPB. Patient eligibility was determined at the precatheterization assessmen...
Hemoglobin adducts of the carcinogenic tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) release 4-hydroxy-1-(3-pyridyl)-1-butanone (HPB) upon mild base or acid hydrolysis. HPB has been detected in hydrolysates of hemoglobin from smokers and snuff dippers and has been proposed as a dosimeter of exposure to and metabolic activation of NNK in people exposed to toba...
There are two fundamental problems concerning equivalence relations in concurrency. One is: for which system classes is a given equivalence decidable? The second is: when do two equivalences coincide? Two well-known equivalences are history preserving bisimilarity (hpb) and hereditary history preserving bisimilarity (hhpb). These are both ‘independence’ equivalences: they reflect causal depende...
IMPORTANCE Malignant neoplasms of the hepatopancreaticobiliary (HPB) system constitute a significant public health problem worldwide. Treatment coordination for these tumors is challenging and can result in substandard care. Referral centers for HPB disease have been used as a strategy to improve postoperative outcomes, but their effect on accomplishing regionalization of care and improving qua...
