In Saccharomyces cerevisiae, nascent carboxypeptidase Y (CPY) is directed into the endoplasmic reticulum by an NH2-terminal signal peptide that is removed before the glycosylated protein is transported to the vacuole. In this paper, we show that this signal peptide does not function in mammalian cells: CPY expressed in COS-1 cells is not glycosylated, does(More)
The aims of the present study were (a) to maintain the structure and function of the small intestine of the piglet after weaning, and (b) to compare the capacity in vivo of sucking and weaned piglets to digest oral boluses of lactose and sucrose and absorb their monosaccharide products. Piglets were fed on cows' whole milk ad libitum every 2 h for 5 d after(More)
A 17.5 kDa protein was isolated from porcine whey by reverse phase HPLC and identified as a putative whey acidic protein (WAP) homologue by sequencing 35 and 40 amino acid residues of the amino- and carboxy-terminus respectively. Degenerate oligonucleotides to both of these amino acid sequences were designed and used in reverse transcriptase PCR with RNA(More)
The capacity of intestinal lactase (EC 3.2.1.23) of piglets to hydrolyse lactose in vivo was investigated by measuring the response of blood galactose to doses of lactose, galactose plus glucose and both whole and skimmed milk. Following the administration of oral doses of lactose dissolved in water to piglets from 2 to 18 d of age the adjusted galactose(More)
We wish to report the preparation of several bis(ter-tiary phosphine)platinum(Il) metallocycles, and kinetic evidence indicating that certain of these substances have much higher thermal stability than analogous acyclic dialkylplatinum(II) compounds. Metallo-cycles are of current interest for two reasons. First, members of this class of compounds have been(More)
Surgery of the middle ear is a delicate process that requires the surgeon to manipulate the ossicles, the smallest bones in the body. Excessive force applied to the ossicles can easily be transmitted through to the inner ear which may cause a permanent sensorineural hearing loss. An instrument was required to measure the forces applied to cadaveric temporal(More)
