Work on cytotoxic analogs of luteinizing hormone-releasing hormone (LH-RH), somatostatin and bombesin, designed for targeting chemotherapy to peptide receptors on various cancers, is reviewed here as the project is at advanced stages of development and clinical trials are pending. Cytotoxic analogs of LH-RH, AN-152 and AN-207, containing doxorubicin (DOX)(More)
The spatial and temporal visual sensitivity to drifting sinusoidal gratings was studied in 105 neurons of the suprageniculate nucleus of the feline thalamus. Extracellular single-unit recordings were performed in halothane-anesthetized, immobilized, artificially ventilated cats. Most suprageniculate nucleus cells were strongly sensitive to the direction of(More)
OBJECTIVE We investigated the effect of early jejunal feeding on septic complications and mortality rate in patients with acute pancreatitis in a two-phase, prospective, controlled study. METHODS In the first, randomized phase of the study, conventional parenteral nutrition was compared with early (within 24-72 h after the onset of symptoms) enteral(More)
Targeted chemotherapy is a modern approach aimed at increasing the efficacy of systemic chemotherapy and reducing its side effects. The peptide receptors expressed primarily on cancerous cells can serve as targets for a selective destruction of malignant tumors. Binding sites for LHRH (now known in genome and microarray databases as GNRH1), were found on(More)
The atomic force microscope is a high-resolution scanning-probe instrument which has become an important tool for cellular and molecular biophysics in recent years but lacks the time resolution and functional specificities offered by fluorescence microscopic techniques. To exploit the advantages of both methods, here we developed a spatially and temporally(More)
The role of the caudate nucleus (CN) in motor control has been widely studied. Less attention has been paid to the dynamics of visual feedback in motor actions, which is a relevant function of the basal ganglia during the control of eye and body movements. We therefore set out to analyse the visual information processing of neurons in the feline CN.(More)
BACKGROUND Edrecolomab is a murine monoclonal antibody to the cell-surface glycoprotein 17-1A, which is expressed on epithelial tissues and on various carcinomas. Preliminary data suggested that it might be of use in the adjuvant treatment of patients with resected stage III colon cancer. We did a randomised trial in 27 countries to determine the effect of(More)
PURPOSE The receptors for luteinizing hormone-releasing hormone receptor (LHRH-R) are found in >50% of human breast cancers. Doxorubicin (DOX) was linked to [D-Lys(6)]LHRH to form a cytotoxic conjugate, AN-152, which can be targeted to tumor cells expressing LHRH-R. We evaluated the effects of AN-152 on the estrogen-independent, DOX-resistant human mammary(More)
OBJECTIVE Eighty percent of human ovarian and endometrial cancers express receptors for luteinizing hormone-releasing hormone (LHRH-R). These receptors can be used for targeted chemotherapy with agents such as AN-152, in which doxorubicin is linked to analog [D-Lys(6)]-LHRH. Direct receptor-mediated antiproliferative effects of AN-152 have been shown in(More)
Sensorimotor co-ordination in mammals is achieved predominantly via the activity of the basal ganglia. To investigate the underlying multisensory information processing, we recorded the neuronal responses in the caudate nucleus (CN) and substantia nigra (SN) of anaesthetized cats to visual, auditory or somatosensory stimulation alone and also to their(More)
