AIM Percutaneous Endoscopic Gastrostomy (PEG) placement is a useful but invasive method. Recently, the hemodynamic change of ultrathin transnasal esophagogastroduodenoscopy (transnasal EGD) was reported as less than that of conventional transoral EGD (transoral EGD). This study compared hemodynamic changes between transnasal EGD and transoral EGD in the setting of PEG placement using a modified...

A modi®ed two stage in vitro digestion method was used to study the effects of rate of PEG addition (0±1100 mg/g DM) on dry matter (IVDMD) and nitrogen digestibility (IVND) of freeze dried leaf materialfromactivelygrowingshootsofCalliandracalothyrsus (Calliandra)andLeucaenaleucocephala cv. Cunningham (Leucaena). For both species, IVDMD and IVND increased asymptotically with PEG rate; the IVND r...

The triblock 18β-glycyrrhetinic acid-poly(ethylene glycol)18β-glycyrrhetinic acid conjugates (GA-PEG-GA) based self-assembled micelles were synthesized and characterized by FTIR, NMR, transmission electron microscopy, and particle size analysis. The GA-PEG-GA conjugates having the critical micelle concentration of 6 × 10(-5) M were used to form nanosized micelles, with mean diameters of 159.21 ...

This study first reports the pharmacokinetic disposition of polyethylene glycol (PEG)-modified salmon calcitonin (sCT) based on the number of attached PEG molecules. PEG-modified sCT was prepared by covalent linkage with succinimidyl carbonate monomethoxy polyethylene glycol. Mono- and di-PEG-sCTs were separated by size exclusion and reverse phase HPLC, and radioiodinated by the chloramine-T me...

One of the major challenges faced by researchers in linguistics and psycholinguistics India is lack corpora linguistic information such as word frequency, letter phonological phonetic data on sounds, morphological words, etc, Indian languages. When they do not get stimulus material readily available any corpus, resort to preparing a set that meets criteria for their specific study. This paper p...

BACKGROUND/AIMS Although percutaneous endoscopic gastrostomy (PEG) is the method of choice for long-term enteral nutrition, feeding-related adverse events such as aspiration pneumonia and peristomal leakage can impede the use of PEG. Percutaneous endoscopic transgastric jejunostomy (PEG-J) using large-bore jejunal tubes may help by circumventing gastric passage during enteral nutrition and impr...

The aim of the current study was to investigate the antitumor potential of poly (D,L-lactic-co-glycolic acid) microspheres (PLGA MSs) containing polyethylene glycol (PEG)-conjugated (PEGylated) tumor necrosis factor-related apoptosis-inducing ligand (PEG-TRAIL). PEG-TRAIL PLGA MSs were prepared by using a water-in-oil-in-water double-emulsion method, and the apoptotic activities of supernatants...

Poly(ethylene glycol) (PEG) is a common building block for complex functional molecules. Because of its chain flexibility and hydrophilicity, it is widely used in bioconjugation chemistry. Modern applications require PEGs of high purity, hence well-defined, monodisperse PEG oligomers are gaining more attention. Here we report a large-scale synthetic procedure for monodisperse oligo(ethylene gly...
