This paper describes the preparation of iron oxide nanoparticles, surface of which was coated with extremely high immobilization stability and relatively higher density of poly(ethylene glycol) (PEG), which are referred to as PEG protected iron oxide nanoparticles (PEG-PIONs). The PEG-PIONs were obtained through alkali coprecipitation of iron salts in the presence of the PEG-poly(4-vinylbenzylp...
هدف پژوهش حاضر، بررسی گوارش پذیری ماده آلی پوسته پسته (پسماند کشاورزی آلوده کننده محیط زیست) به روش آزمایشگاهی (omd) با استفاده از شیرابه شکمبه گوسفند تالشی بود. جیره گوسفندان شامل 34 درصد پوسته پسته، 29 درصد تفاله انگور، 32 درصد یونجه و 5 درصد دانه جو بود. ترکیب شیمیایی و ترکیبات فنولیک پوسته پسته صنعتی خشک (idph) و آفتاب خشک (sdph) تعیین شد. میزان omd پوسته پسته در روز صفر، 3 و 30 دوره مصرف ب...
To evaluate the effect of coupling of recombinant human serum albumin (rHSA) onto the surface of poly(ethylene glycol)-modified liposome (PEG liposome) on the in vivo disposition characteristics of liposomal doxorubicin (DXR), the pharmacokinetics and tissue distribution of DXR were evaluated after intravenous administration of rHSA-modified PEG (rHSA/PEG) liposomal DXR into tumor-bearing rats....
University of Wisconsin (UW) solution is not optimal for preservation of marginal organs. Polyethylene glycol (PEG) could improve protection. Similarly formulated solutions containing either 15 or 20 g/L PEG 20 kDa or 5, 15 and 30 g/L PEG 35 kDa were tested in vitro on kidney endothelial cells, ex vivo on preserved kidneys, and in vivo in a pig kidney autograft model. In vitro, all PEGs provide...
BACKGROUND Many patients with cancer or other systemic illnesses can experience malnutrition. One way to mitigate malnutrition is by insertion of a percutaneous endoscopic gastrostomy feeding tube (PEG tube). The goal of this retrospective matched cohort study is to evaluate if PEG tube placement improved nutritional status and overall survival (OS) in advanced gastroesophageal (GE) cancer pati...
Poly(ethylene glycol) (PEG) has been studied as a drug-carrier for proteins, but not for small peptides. Laminin, a cell adhesive protein, has Tyr-Ile-Gly-Ser-Arg (YIGSR) sequence and peptides containing this sequence inhibit experimental metastasis. We have studied PEG hybrids of YIGSR and other small laminin-related peptides. In a previous paper, we reported preparation of YIGSR-PEG hybrids b...
pigeonpea (cajanus cajan (l) millsp.) is a drought tolerant legume widely grown in the arid and semi-arid tropics of the world which possesses a deep and extensive root system that succors a number of important physiological and metabolic functions to cope with drought. application of available functional genomics approaches to improve productivity under water deficit requires a better understa...
BACKGROUND AND PURPOSE Stroke guidelines recommend time-limited trials of nasogastric feeding prior to percutaneous endoscopic gastrostomy (PEG) tube placement. We sought to describe timing of PEG placement and identify factors associated with early PEG for acute ischemic stroke. METHODS We designed a retrospective observational study to examine time to PEG for ischemic stroke admissions in t...
The development of silicone elastomers with hydrophilic functionality in the form of PEG substituents provides benefits beyond the rheology modification (thickening) that can be achieved with silicone elastomers that lack functional substituents. We have shown that PEG-modified dimethicone crosspolymer (PEG-DCP) is an effective emulsifier for water-in-silicone (w/s) emulsions where the continuo...
