1. The effect of muscarinic antagonists considered to be selective for M1 receptors (pirenzepine) and for M2 receptors (gallamine) were studied on bronchoconstriction and bradycardia elicited by stimulation of the vagal nerves and by i.v. acetylcholine (ACh) in anaesthetized rabbits. 2. Pirenzepine was equipotent as an antagonist of ACh-induced responses at(More)
Groups of pregnant mice were irradiated at selected times between 10.00 hours on gestation day 7 and 16.00 hours on day 8. Each group received 0.39 Gy of neutrons or 1.60 Gy of X-rays, or was sham irradiated. We identified a period of high susceptibility of the embryos to radiation-induced exencephalia, anophthalmia and prenatal mortality early in gestation(More)
The location of neuronal inhibitory muscarinic receptors in pulmonary parasympathetic nerves was investigated in vivo and in vitro. The effects of an agonist for neuronal muscarinic receptors (pilocarpine) and an antagonist (gallamine) were tested on contractions of airway smooth muscle induced by pre- and postganglionic cholinergic nerve stimulation. In(More)
1. The effect of pirenzepine, a muscarinic antagonist considered to be selective for M1 receptors, was studied on bronchoconstriction and bradycardia elicited by preganglionic stimulation of the parasympathetic vagal nerves and by i.v. injections of acetylcholine (ACh) in anaesthetized guinea-pigs. 2. Pirenzepine was equipotent in the heart and lung as an(More)
Multiple myeloma (MM) is an incurable malignancy with an unmet need for innovative treatment options. Histone deacetylase inhibitors (HDACi) are a new class of anticancer agent that have demonstrated activity in hematological malignancies. Here, we investigated the efficacy and safety of HDACi (vorinostat, panobinostat, romidepsin) and novel combination(More)
N-methyl-2-pyrrolidone (NMP) is a common solvent and drug vehicle. We discovered unexpected antineoplastic and immunomodulatory activity of NMP in a cMYC-driven myeloma model. Coincident to this, NMP was identified as an acetyllysine mimetic and candidate bromodomain ligand. Accordingly, NMP-treated cells demonstrated transcriptional overlap with(More)
The dose equivalent to air carrier crewmembers from galactic cosmic radiation was estimated for each of 32 nonstop flights on a variety of routes to and from, or within, the contiguous United States. Flying times were from 0.4 to 13 hours. The annual dose equivalents received on the flights ranged from 0.2 to 9.1 mSv (20 to 910 mrem), or 0.4 to 18% of the(More)
OBJECTIVE Carboplatin is one of the most effective chemotherapeutic drugs for the treatment of ovarian cancer. It has simple pharmacokinetics and a predictable toxicity profile. The dose can be calculated effectively based on a patient's renal function as defined by the glomerular filtration rate (GFR). The measurement of the GFR is best done using(More)
In order to stimulate antigen presentation and T cell activity against cancer, we treated three different tumor models in mice with the monoclonal antibodies anti-CD40 plus anti-CD137 (BiMab). In a subcutaneous transplantable MC38 colon cancer model, there was significant enhancement in the survival of mice following BiMab treatment. Anti-CD40 has shown(More)
Striking and pronounced growth responses to the gibberellins as plant regulators and hormones are well known and readily produced in suitable plants. It was our purpose to study the effects of such growth responses on the concentrations of plant lipids and on the concentrations of antioxidants that are synthesized in plants. Growth changes were induced in(More)
