Cyprinid herpesvirus 3 (CyHV-3) causes a lethal disease in common and koi carp (Cyprinus carpio). The present study investigated the ability of CyHV-3 to infect common carp during the early stages of its development (from embryos to fingerlings) after inoculation by immersion in water containing the virus. Fish were inoculated at different times after hatching with a pathogenic recombinant CyHV...

background: childhood masturbation (cm) is considered a variant of normal sexual behavior; however, it is commonly misdiagnosed as epilepsy and movement disorders. as the first study from iran, we analyzed a large population of infants and children with cm in a case-control study and evaluated the value of mucus in urine analysis as an alternative diagnostic tool for cm. methods: a total of 623...

Anabas testudineus is a sturdy freshwater fish that can live in polluted environment due to the epidermal mucus (EM) protects from pathogens or germs. This study explored functional properties of EM as potential antimicrobial and anticancer agent. Inactive Pseudomonas aeruginosa was introduced into tanks stimulate production EM. stimulus significantly increased by more than 100% after 10 days s...

Mucus hypersecretion from hyperplastic airway goblet cells is a hallmark of chronic obstructive pulmonary disease (COPD). Although cigarette smoking is thought to be involved in mucus hypersecretion in COPD, the mechanism by which cigarette smoke induces mucus overproduction is unknown. Here we show that activation of epidermal growth factor receptors (EGFR) is responsible for mucin production ...

The influence of the sympathetic nervous system and adrenergic agonists on flow rate and secretion of epidermal growth factor (EGF) from Brunner's glands has been investigated in the rat. Chemical sympathectomy by administration of 6-hydroxydopamine increased volume secretion and output of EGF from Brunner's glands but depleted the glands of EGF. Infusion of noradrenaline, an alpha-adrenergic a...

background: the airway surface liquid (asl), which is a fluid layer coating the interior epithelial surface of the bronchi and bronchiolesis, plays an important defensive role against foreign particles and chemicals entering lungs. objective: numerical investigation has been employed to solve two-layer model consisting of mucus layer as a viscoelastic fluid and periciliary liquid layer as a newt...

Airway mucus hypersecretion is a significant clinical and pathological feature of chronic inflammatory airway diseases. Its clinical presentations include recurrent coughing and phlegm. Airway mucus is closely associated with the occurrence, development and prognosis of chronic inflammatory airway diseases and critically affects the lung function, quality of life, hospitalization rate and morta...
