Metastatic cancers adopt certain properties of normal cells in developing or regenerating organs, such as the ability to proliferate and alter tissue organization. We find here that activity of the Hedgehog (Hh) signalling pathway, which has essential roles in developmental patterning, is required for regeneration of prostate epithelium, and that continuous(More)
The effect of specific chemotherapy on hepatic fibrosis was studied in Swiss albino mice infected with Schistosoma mansoni. The effect of treatment with praziquantel at 8, 12, and 20 weeks postinfection on fibrosis was assessed by determination of total hepatic collagen content, ratio of type III/I + III collagen, granuloma volume, and histopathological(More)
This study aimed to describe a short-term ex vivo assay to predict response to epidermal growth factor receptor (EGFR) targeted therapy (gefitinib) in adenocarcinoma patients. Four patients with locally advanced esophageal adenocarcinoma were treated with gefitinib (250 mg/day) for 14 days and pharmacokinetic (PK) studies were conducted to monitor plasma(More)
The filtrate broth as well as mycelium of the new strain Streptomyces erythrochromogenes nov. sp. isolated from Saudi Arabian soil, produce the antitumor antibiotic daunomycin 1 and two anthracyclic derivatives: 7-deoxy 13-dihydrodaunomycinone 2 and 7-deoxy daunomycinone 4. The biotransformation of 1 to 2 and 4 by an acellular enzyme preparation from the(More)
Efforts have been done to recover proteins from waste liquors rich in protein in a soluble form. Cheese whey and animal bloods are by-products from the manufacture of cheese and meat. It contains a variety of proteins which can be reclaimed. The efficiency of protein precipitation from the sweet-cheese whey by the use of hydroxyethyl cellulose (HEC) was(More)
