Waterborne poly(urethane urea)s (PUDs) containing graphene derivatives with different morphologies and surface polarities were synthesized via in situ polymerization by using the acetone method. Sm...

The coronary vasoconstrictor properties of digitals were evaluated in 61 anesthetized, openchest dogs after coronary sinus cannulation and under conditions of a constant heart rate (atrioventricular pacing) and near-constant blood pressure. The contribution of alpha adrenergic receptor stimulation to the digitalis-induced increase in coronary vascular resistance (CVR) was examined. With Na pent...

Achieving a unique combination of stiffness, strength, extensibility, and toughness in sol-cast poly(urethane–urea) (PU) copolymer films is challenge since these properties are—in general—mutuall...

The expression of nonsteroidal anti-inflammatory drug-activated gene-1 (NAG-1) inhibits gastrointestinal tumorigenesis in NAG-1 transgenic mice (C57/BL6 background). In the present study, we investigated whether the NAG-1 protein would alter urethane-induced pulmonary lesions in NAG-1 transgenic mice on an FVB background (NAG-1). NAG-1 mice had both decreased number and size of urethane-induced...

The expression of nonsteroidal anti-inflammatory drug-activated gene-1 (NAG-1) inhibits gastrointestinal tumorigenesis in NAG-1 transgenic mice (C57/BL6 background). In the present study, we investigated whether the NAG-1 protein would alter urethane-induced pulmonary lesions in NAG-1 transgenic mice on an FVB background (NAG-1(Tg+/FVB)). NAG-1(Tg+/FVB) mice had both decreased number and size o...

Macrophages have established roles in tumor growth and metastasis, but information about their role lung promotion is limited. To assess the of macrophages tumorigenesis, we developed a method minimally invasive, long-term macrophage depletion by repetitive intratracheal instillation liposomal clodronate. Compared with controls treated doses PBS-containing liposomes, resulted marked reduction n...

1. The inhibition of oxygen consumption produced by a series of concentrations of ethyl carbamate has been measured in the protozoan Tetrahymena geleii. 2. The relation found between the narcotic concentration and its effect on respiration leads to the conclusion that urethane has two distinct modes of action in this cell. The respiratory data can be accurately predicted by assuming that the in...

Previous studies have shown that induction of 2kidney -1clip Goldblatt hypertension (2K-1C) induction in rats eliminates hypertensive response after inactivating of the central nucleus of the amygdale (ACe). The present study investigated the possibility of alteration in local renin angiotensin system (RAS) activity in ACe after hypertension induction. Clamps were placed on the left renal arter...

The oxidation of glucose by yeast is inhibited by urethane, and at sufficiently high concentrations of the inhibitor oxygen uptake may be suppresed completely. However, no direct proportionality exists between the degree of inhibition and urethane concentration. This discontinuity in the relationship between degree of inhibition and concentration of urethane has been adduced by Fisher and Stern...
