Parsing Expression Grammar (PEG) encodes a recursivedescent parser with limited backtracking. Its properties are useful in many applications. In its appearance, PEG is almost identical to a grammar in the Extended Backus-Naur Form (EBNF), but may define a different language. Recent research formulated some conditions under which PEG is equivalent to its interpretation as EBNF. However, PEG has ...

A lot of people in the world choose rice as their main source carbohydrate beside maize and wheat. The increasing population make demand. Increasing demand doesn’t followed by supply. In order to solve that problem, researcher try find a new paddy cultivar which is can be planted dry area. This research aims study osmotic pressure still accepted var. Sintanur, LD50 (lethal dose 50) value especi...

PURPOSE Percutaneous endoscopic gastrostomy (PEG) can improve nutritional status and reduce the amount of time needed to feed neurologically impaired children. We evaluated the characteristics, complications, and outcomes of neurologically impaired children treated with PEG. METHODS We retrospectively reviewed the records of 32 neurologically impaired children who underwent PEG between March ...

BACKGROUND There has been debate over the indications for percutaneous endoscopic gastrostomy (PEG) in recent years in Japan. In addition, the level of satisfaction of patients and patient's family after PEG remains unclear. The aim of this study was to investigate the current status of PEG and the level of satisfaction of patients and patients' families after PEG in Japan. METHODS We reviewe...

In this study, novel hydrophilic multiblock copolymers composed of semi-crystalline poly(ε-caprolactone) [PCL] blocks and amorphous blocks consisting of poly(D,Llactide) (PDLA) and poly(ethylene glycol) (PEG) [PDLA-PEG] were synthesized. The block ratio of these [PDLA-PEG]-b-[PCL] multiblock copolymers was varied and the degradation of implants prepared of these polymers by hot melt extrusion (...

Intravesical instillation of antitumor agents following transurethral resection of bladder tumors is the standard strategy for the treatment of superficial bladder cancers. However, the efficacy of current intravesical instillation is limited partly due to the poor permeability of the urothelium. We therefore aimed to develop a high-penetrating, target-releasing drug delivery system to improve ...

BACKGROUND Poly (ethylene glycol) (PEG) has attracted broad interest for tissue engineering applications. The aim of this study was to synthesize 4-arm -PEG-20kDa with the terminal group of diacrylate (4-arm-PEG-DA) and evaluate its dual functionality for decellularized porcine aortic valve (DAV) based on its mechanical and biological properties. METHODS 4-arm-PEG-DA was synthesized by graft ...

INTRODUCTION Polyethylene-glycolated (PEG)-asparaginase (PEG-ASP) is a crucial component of pediatric acute lymphoblastic leukemia therapy. Although hypersensitivity reactions to PEG-ASP occur less frequently than with other formulations, they are not uncommon and have an adverse impact on patient outcomes. Intravenous (IV) administration of PEG-ASP reduces patient pain and anxiety and is being...
