Suppose E and F are Banach lattices such that E* and F have order-continuous norms. In [4] Dodds and Fremlin (cf. also [1]) showed that if T: E F is a positive compact operator and 0 < S < T then S is also compact. Aliprantis and Burkinshaw [1] showed by examples that the hypotheses on E and F are necessary. In [2] they asked whether a similar result is true for Dunford-Pettis operators, under ...

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic entity characterized by headaches, altered mental status, seizures, visual loss, and characteristic imaging pattern in brain MRI. The cause of PRES is not yet understood. We report a case of a 27-year-old woman that developed PRES after the use of FOLFOX 5 (oxaliplatin/5-Fluoracil/Leucovorin) chemotherapy for a colorecta...

BACKGROUND Irinotecan (CPT11) has established activity against advanced colorectal cancer without cross-resistance with 5-fluorouracil + leucovorin-based therapy. We conducted this pilot study to evaluate the efficacy and tolerance of combination treatment with irinotecan and 5-fluorouracil (5-FU) for patients in whom combination treatment with oxaliplatin with 5-FU + leucovorin has failed. M...

PURPOSE Erlotinib (Tarceva) is a potent epidermal growth factor receptor (HER1) inhibitor. Infusional 5-fluorouracil (5-FU), leucovorin, and oxaliplatin (FOLFOX) is a standard therapy for colorectal cancer. This trial assessed the maximum tolerated dose (MTD), safety, preliminary efficacy, and pharmacokinetics of erlotinib combined with FOLFOX. EXPERIMENTAL DESIGN Patients with advanced solid...

Folate cofactors are one-carbon donors essential for the biosynthesis of purines and thymidylate. Mammalian cells are devoid of folate biosynthesis and are therefore folate auxotrophs that take up folate vitamins primarily via the reduced folate carrier (RFC). In this study, we showed that the human RFC (hRFC) gene can serve as a novel selectable marker for the overproduction of recombinant pro...

OBJECTIVE The risk of venous thromboembolism has been reported to increase when receiving bevacizumab. Many cancer patients are reported to have elevated D-dimer levels. It is not clear what D-dimer level might indicate an increased risk of venous thromboembolism in the colorectal cancer patients treated with bevacizumab-containing chemotherapy. METHODS The D-dimer levels and any event concur...

There is evidence that before pteroylglutamic acid (PGA) can carry out certain catalytic functions in animal tissues it must first be converted to citrovorum factor (CF). This conversion has been studied in rat liver slices by Nichol and Welch (l), who found that the conversion was enhanced by ascorbic acid. Since Streptococcus faecalis utilizes either PGA or CF to meet its growth requirement f...

The isolation of N10 formylfolic acid' from natural materials has been reported by several groups of workers (Rauen et al., 1952; Rauen and Jaenicke, 1953; Greenberg, 1954a; Silverman et al., 1954). It was concluded that the compound had been derived either from the degradation of a labile intermediate involved in the conversion of a bound (microbiologically inactive) form of folic acid in live...
