A phase I clinical evaluation of liposome-entrapped doxorubicin (Lip-Dox) in patients with primary and metastatic hepatic malignancy.

Liposome-entrapped doxorubicin (Lip-Dox) was evaluated in two phase I clinical trials in patients with hepatic malignancy. Patients with metastases from primary gastric or colonic tumours and patients with hepatoma were eligible. Lip-Dox was extremely well tolerated and acute toxicities such as nausea and vomiting were totally eliminated; no antiemetics were used even at doses of 80 mg/m2.

Effects of reading and writing on cerebral laterality in good readers and children with dyslexia.

The present study evaluated the idea that the hemisphere-specific cognitive demands of reading and writing may induce task-specific maladaptive patterns of language lateralization in children with dyslexia. Situation-specific lateralization was examined in a repeated measures design under three dichotic listening conditions: baseline, concurrent reading, and concurrent writing. Twelve males with phonological dyslexia, 8 to 12 years old, were compared to 12 age-matched and 12 younger reading-matched good readers.

Hemostasis and cold knife cone biopsy: a prospective randomized trial comparing a suture versus non-suture technique.

Two methods of obtaining hemostasis after cold knife cone biopsy were compared in a prospective randomized trial involving 200 patients. One method relied primarily on hemostatic sutures, and the other involved the use of a styptic solution (Monsel's solution) and vaginal pack, thus avoiding the use of sutures altogether. The short- and long-term morbidity in these two groups were compared and 12-month follow-up was completed.

Synthesis, processing, and secretion of the Marek's disease herpesvirus A antigen glycoprotein.

The 57,000- to 65,000-dalton (Da) Marek's disease herpesvirus A (MDHV-A) antigen glycoprotein (gp57-65) has a 47,000-Da unglycosylated precursor polypeptide (pr47), as determined by immunological detection after cell-free translation of infected-cell mRNA. Cleavage of its signal peptide yielded a 44,000-Da precursor polypeptide molecule (pr44), detected both in vivo after tunicamycin inhibition of glycosylation and in vitro after dog pancreas microsome processing of pr47. High-resolution pulse-chase studies showed that pr44 was quickly glycosylated (within 1 min) to nearly full size, a rapid processing time consistent with a cotranslational mode of glycosylation.
