Human glycol ether poisonings are sparsely reported in the medical literature. We describe a healthy 22-month-old boy who accidentally drank up to 330 mL of brake fluid containing a 75% bleed of various glycol ethers (5%-50% polyethylene glycol monomethyl ether, 15%-40% triethylene glycol monoethyl ether, 1%-30% triethylene glycol monomethyl ether, 1%-25% triethylene glycol monobutyl ether, 1%-...

Cationic polyacrylamide (CPAM) was synthesized by aqueous two-phase polymerization technique using acrylamide (AM) and dimethylaminoethyl methacrylate methyl chloride (DMC) as raw materials, aqueous polyethylene glycol 20000 (PEG 20000) solution as dispersant, 2,2′-azobis(2-amidinopropane) dihydrochloride (V-50) as initiator and poly(dimethylaminoethyl methacrylate methyl chloride) (PDMC) as st...

PURPOSE The aim of this study was to compare the efficacy and patient tolerance of two bowel preparations for colonoscopy. METHODS Three hundred twenty-three consecutive patients undergoing colonoscopy were randomly assigned to receive either oral sodium phosphate, or 2 liters of polyethylene glycol solution preceded by the stimulant laxative bisacodyl. Patients were asked to record the effec...

Effective colonoscopy requires an adequate level of cleansing as a basic component. This review will describe a compact review about general considerations in bowel preparation for colonoscopy and specific considerations for various patients. A low-fiber diet instead of a regular diet on the day before colonoscopy is an independent predictor of adequate bowel preparation. Improved bowel cleansi...

The increased demand for portable electronic devices and electric vehicles has resulted in an exponential increase lithium-ion battery (LIB) waste, becoming turn important secondary source critical metals. Electrowinning is a commonly used method to recover base precious metals from solution, which can also be valuable spent LIBs. This study unveiled the cobalt electrochemical recovery using mo...

Materials: Chemicals were purchased from Sigma-Aldrich BV and used as received: the surfactants, sodium bis(2-ethylhexyl)sulphosuccinate (Na-AOT, 99%) and 4(1,1,3,3-Tetramethylbutyl)phenyl-polyethylene glycol (Triton-X 100, 99.999%); the solvents, n-heptane (99.9%) and toluene (≥99.5%); the metal precursors, chloroplatinic acid hydrate (99.9%), iron chloride (≥99%), cobalt acetate tetrahydrate ...

nano-sized γ-al2o3 was synthesized successfully by a simple method using al2(so4)3·18h2o as aluminium source and in the presence of polyethylene glycol (peg 2000). ftir spectroscopy, x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscope (tem) were used to characterize the structure and morphology of synthesized powder. the results showed that peg playe...

it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...

An experimental procedure developed to concentrate fungal viruses from large volumes of homogenized mycelia with water-soluble polymers, such as polyethylene glycol, possesses advantages over more conventional methods. Concentration of the Penicillium stoloniferum fast-moving virus from mycelial homogenates after addition of polyethylene glycol was rapid and produced large quantities of pure vi...
