The maximum permissible concentration (MPC) of chloroprene was set at 2 mg/m3 in the USSR in the 1940's. The existing MPC is 4 mg/m3. The threshold of systemic effects as a result of chronic chloroprene exposure is l.69 mg/m3. However, the threshold for embryotoxic and mutagenic effects is 0.15 mg/m3. In consideration of this information, setting a new MPC for chloroprene at 0.05 mg/m3 is reco...

H2-M3 is a class Ib MHC molecule that binds a highly restricted pool of peptides, resulting in its intracellular retention under normal conditions. However, addition of exogenous M3 ligands induces its escape from the endoplasmic reticulum (ER) and, ultimately, its expression at the cell surface. These features of M3 make it a powerful and novel model system to study the potentially interrelate...

ing for muscarinic receptors (m1, m2, m3, m4, m5) have been identified and cloned. Pharmacologically, four subtypes (M1, M2, M3, M4) have been defined. 6—8) Among these muscarinic receptor subtypes, M3 receptors are localized in smooth muscle and mucosal glands and mediate contraction and mucus secretion. M1 receptors, localized to the post-ganglionic cholinergic nerve terminals and glands, fac...

UNLABELLED INTRODUCTION Potential health damage by environmental emission of tobacco smoke (environmental tobacco smoke, ETS) has been demonstrated convincingly in numerous studies. People, especially children, are still exposed to ETS in the small space of private cars. Although major amounts of toxic compounds from ETS are likely transported into the distal lung via particulate matter (PM)...
