1.	Subacute Sclerosing Panencephalitis (SSPE) 02/01/2001 - "In the first step, sewage sludge was lyophilized, treated by sonication with a mixture of methanol and chloroform and finally cleaned up using a sequential solid phase extraction (SSPE) with an octadecylsilica cartridge (C18) in series with a polymeric Lichrolut EN cartridge (Lic EN). " 10/01/2000 - "A generic protocol involving the use of sequential solid-phase extraction (SSPE) with octadecylsilica and styrene-divinylbenzene cartridges in series and differential elution was used. "
2.	Neoplasms (Cancer) 07/01/1989 - "The content of prostaglandins in Yoshida tumor ascites fluid was evaluated by extraction of the arachidonic acid metabolites by means of octadecylsilyl-silica chromatography (ODS-extracts). "
3.	Inflammation (Inflammations) 03/30/1984 - "Effects of dexamethasone on chemotactic activity to polymorphonuclear leukocytes (PMN) of a lipophilic fraction collected with the aid of octadecylsilyl silica cartridge from exudates of an allergic inflammation were investigated. "
4.	Hypopituitarism (Sheehan's Syndrome) 06/01/1987 - "Urinary IGF-I was quantitated by RIA after extraction with octadecylsilyl silica cartridges (Sep-Pak C18 cartridge), a method that measures only free IGF-I. The mean urinary immunoreactive IGF-I levels in normal adults (n = 8) and patients with acromegaly (n = 10) or hypopituitarism (n = 9) were 72 +/- 7 (+/- SEM), 225 +/- 34, and 19 +/- 4 pg/mg creatinine, respectively; these mean values were significantly different from one another. "
5.	Hyperglycemia 05/01/1991 - "We conclude that pig plasma PLI levels can be measured by radioimmunoassay after extraction on octadecylsilyl silica and that there is a net pancreatic output of PLI, which is reduced by sympathetic stimulation and enhanced during hyperglycemia."
