e. The Oxford–AstraZeneca COVID‑19 vaccine, sold under the brand names Covishield [31] and Vaxzevria [1] [32] among others, is a viral vector vaccine for the prevention of COVID-19. It was developed in the United Kingdom by Oxford University and British-Swedish company AstraZeneca, [33] [34] [35] using as a vector the modified chimpanzee ...
Human papillomavirus infection ( HPV infection) is caused by a DNA virus from the Papillomaviridae family. [5] Many HPV infections cause no symptoms and 90% resolve spontaneously within two years. [1] In some cases, an HPV infection persists and results in either warts or precancerous lesions. [2] These lesions, depending on the site affected ...
Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.

Medical uses
1. Pharmaceutical-grade PEG is used as an excipientin many pharmaceutical products, in oral, topical, and parenteral dosage forms. 2. PEG is the basis of a number of laxatives (as MiraLax, RestoraLAX, etc.). Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy or for children with constipation. Macrogol (with brand names such as Laxido, Movicol and Miralax) is the generic name for polyethylene glycol used as a laxat...
Chemical uses
1. Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluidin electronic testers. 2. PEG is frequently used to preserve waterlogged wood and other organic artifacts that have been salvaged from underwater archaeological contexts, as was the case with the warship Vasa in Stockholm, and similar cases. It replaces water in wooden objects, making the wood dimensionally stable and preventing warping or shrinking of the wood when...
Biological uses
1. An example study was done using PEG-diacrylate hydrogels to recreate vascular environments with the encapsulation of endothelial cells and macrophages. This model furthered vascular disease modeling and isolated macrophage phenotype's effect on blood vessels. 2. PEG is commonly used as a crowding agent in in vitro assays to mimic highly crowded cellular conditions. Although polyethylene glycol is considered biologically inert, it can form non-covalent complexes with monovalent cations such...
PEG is considered biologically inert and safe by the U.S. FDA. However, a growing body of evidence shows the existence of a detectable level of anti-PEG antibodies in approximately 72% of the population, never treated with PEGylated drugs, based on plasma samples from 1990 to 1999.[further explanation needed] Due to its ubiquity in a multitude of p...
PEG, PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry. Because different applications require different polymer chain lengths, PEG has tended to refer to oligomers and p...
The production of polyethylene glycol was first reported in 1859. Both A. V. Lourenço and Charles Adolphe Wurtz independently isolated products that were polyethylene glycols. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. The reaction is catalyzed by acidic or basic c...
PEO's have "very low singledose oral toxicity", on the order of tens of grams per kg body weight (oral). Because of its low toxicity, PEO is used in a variety of edible products.The polymer is used as a lubricating coating for various surfaces in aqueous and non-aqueous environments. The precursor to PEGs is ethylene oxide, which is hazardous. Ethy...
Messier 56 (also known as M56 or NGC 6779) is a globular cluster in the constellation Lyra.[a] It was discovered by Charles Messier in 1779.[b] It is angularly found about midway between Albireo (Beta (β) Cygni) and Sulafat (Gamma (γ) Lyrae). In a good night sky it is tricky to find with large (50–80 mm) binoculars, appearing as a slightly ...
NGC 6744 (also known as Caldwell 101) is an intermediate spiral galaxy about 30 million light-years away [2] in the constellation Pavo (Peacock). It is considered as a Milky Way mimic in the immediate vicinity, displaying flocculent (fluffy) arms and an elongated core.
NGC 6745 (also known as UGC 11391) is an irregular galaxy about 206 million light-years (63.5 mega- parsecs) away in the constellation Lyra. It is actually a trio of galaxies in the process of colliding . The three galaxies have been colliding for hundreds of millions of years. After passing through the larger galaxy (NGC 6745A), the smaller ...
