Novel therapeutic agents are needed in the adjuvant treatment of gastric cancer. The differentiating agent sodium butyrate (NaBT) inhibits the growth of colon cancer cells; its effects on gastric cancers are not known. The purpose of our study was to

The prognosis for gastric cancer remains dismal; novel agents that target specific molecular pathways are needed as adjuvant therapy. Camptothecin (CPT), on inhibitor of topoisomerase I, is effective in the treatment of certain solid tumors; its effe

Glycine-extended progastrin (G-17-Gly), the immediate biosynthetic precursor to gastrin (G-17), stimulates growth of some gastrointestinal cancers in vitro. The purpose of this study was twofold: to evaluate the effects of G-17-Gly on a human colon c

Effective clinical therapy to augment intestinal absorption of water and electrolytes does not exist; the gut hormone, peptide YY (PYY), is a potent proabsorptive agent in animal models. The purpose of our study was to evaluate the effects of two nov

1. Tin bronze OTsSN3-7-5-1, which has a low cavitation and corrosion—cavitation resistance, should be replaced with more resistant alloys in marine pumps. 2. Of the alloys tested, the corrosion—cavitation resistance in sea water is highest for br

1. Pump materials must be selected according to the data on their corrosion-cavitation resistance as well as their corrosion resistance. 2. Steel Kh34L has good resistance to cavitation of low and medium intensity. 3. Alloys with high corrosion-cavit
