During the dissolution of cocrystal particles, solution-mediated phase transformation (SMPT) can occur either on particle surface (PS-SMPT) or in bulk solution (BP-SMPT). In this study, we compared effect various polymers PS-SMPT and BP-SMPT for first time using carbamazepine saccharine (CBZ-SAC) as a model drug. Polyethylene glycol 6000 (PEG), polyvinylpyrrolidone K-30 (PVP), hydroxypropyl met...
The present study was conducted to prepare sustained release microspheres of naproxen sodium using ethyl cellulose (Ethocel 20 cps) polymer. Three different plasticizers namely polyethyleneglycol 600 (PEG 600), polyethyleneglycol 6000 (PEG 6000) and triethyl citrate (TEC) were used at 10% (wt/wt) and 40% (wt/wt) level of the drug content. Prepared microspheres were characterized with respect to...
Purification and PCR amplification procedures for DNA extracted from environmental samples (soil, compost, and river sediment) were improved by introducing three modifications: precipitation of DNA with 5% polyethylene glycol 8000 (PEG) and 0.6 M NaCl; filtration with a Sepharose 4B–polyvinylpolypyrrolidone (PVPP) spin column; and addition of skim milk (0.3% w/v) to the PCR reaction solution. H...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...
Seeds of pearl millet (Pennisetum glaucum (L) R. Br.) from six provenances of Tunisia were subjected to germination and shoot and root length tests on filter paper treated with polyethylene glycol 6000 (PEG 6000) solutions made up to provide osmotic potentials of 0, -1 and -2 MPa. Mean germination percent for all provenances decreased about 73% in -2 MPa compared to control (0 MPa) treatment. O...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
Background & Aims: Polyethylene glycol (PEG) solution is used as a laxative for the treatment of constipation in children. Due to the preparation of this solution as a compounding ingredient and solution instability as well as unavailability of the exact expiration date of compounding ingredients, it is necessary and important to investigate the stability of PEG solution. Materials & Methods: ...
In Central Europe, European beech (Fagus sylvatica L.) wood has a high potential for the production of construction and decorative materials, with aim replacing Norway spruce, oaks, other traditionally used tree species. However, biological resistance wood—to decaying fungi, molds, insects—is low, in damp conditions its must be increased suitable preservatives or modification methods. present e...
Environmental stresses specially drought, play an important role in decreasing plant growth, particularly during germination in dry and semi dry area. To considering the effect of drought stress caused by polyethylene glycol on germination and characteristics of 2 spices of Sesamum indicum, we had done factorial and complete accidental plot with 4 treatments and 3 times repetition. Experimental...
Polyethylene glycol (Klean-Prep, Norgine) is widely used for bowel cleansing in the United Kingdom. This study compares the efficacy, acceptability and adverse effects of a polyethylene glycol (PEG) solution with sodium phosphate (Fleet Phospho-soda, De Witt) for bowel preparation prior to colonoscopy. Two hundred and nine consecutive patients were prospectively randomised to either PEG or sodi...
