Paraquat (PQ) is a commonly used herbicide that induces oxidative stress via reactive oxygen species (ROS) generation. This study aimed to investigate the effects of the antioxidant N-acetylcysteine (NAC) against PQ-induced oxidative stress in mice. Male Balb/C mice (24) were randomly divided into 4 groups and treated for 3 weeks: 1) control (saline), 2) NAC (0.5% in diet), 3) PQ (20 mg/kg, IP)...

bachground: paraquat (pq) intoxication manifests with pulmonary edema and fibrosis, heart failure, hepatic failure, and sometimes convulsions. in severe cases, the patients may die within the early hours. at best conditions, the conventional therapeutic methods can only save less than 50% of the victims of intentional pq intoxication. the aim of this study was to evaluate the outcome of new the...

In supersymmetric theories, the Peccei-Quinn symmetry has a complex extension as a symmetry of the superpotential, so that the scalar potential always has an almost flat direction, the dilaton. We discuss how coherent oscillation of the dilaton affects axion cosmology. We stress that the dilaton decay, if its dominant mode is not into axions, releases large entropy at a late epoch of the Univer...

Mucins are highly glycosylated secretary proteins produced by most epithelial cells. Hypersecretion of mucins is one of the prominent symptoms of several airway diseases, including asthma, cystic fibrosis, nasal allergy, rhinitis, and sinusitis. Paraquat (PQ), a common herbicide, has been associated with pulmonary damage and is a potent reactive oxygen species (ROS) producer. However, until now...

A bosonized-field-theory representation of spin operators in the uniform-field-induced Tomonaga-Luttinger-liquid (TLL) phase in spin-1 Haldane chains is formulated by means of the non-Abelian (Tsvelik’s Majorana fermion theory) and the Abelian bosonizations and Furusaki-Zhang technique [Phys. Rev. B 60, 1175 (1999)]. It contains massive magnon fields as well as massless boson fields. From it, a...
