Rice snails are one of the pests that have potential to cause high losses rice plants. snail mucus contains glycosaminoglycans, proteoglycans, glycoprotein enzymes, copper peptides, metal ions, collagen, elastin, glycolic acid, allantoin, antimicrobial peptides and vitamin C. Vitamin C or ascorbic acid is vitamins needed by body functions as a help process in body's metabolism. To determine lev...

Cervical mucus hydration increases during the fertile interval prior to ovulation. Since sperm can only penetrate mucus having a high water content, cervical secretions provide a reliable marker of the fertile days of the menstrual cycle. This article develops a Bayesian approach for modeling of daily observations of cervical mucus, and applies the approach to assess heterogeneity among women a...

Mucus hyperproduction in asthma results from Th2-induced airway inflammation. Controversy exists about the precise mechanism of this Th2 effect. Although we showed that mucus can be induced by Th2 cells in the absence of interleukin (IL)-4, IL-5, eosinophils, and mast cells, but not without IL-4Ralpha signaling, others demonstrated that IL-4 and IL-9 can directly stimulate airway epithelial muc...

A new mathematical model of the transport of mucus and periciliary liquid (PCL) in the airways by cilia is presented. Mucus is represented by a linearly viscoelastic fluid, the mat of cilia is modelled as an 'active porous medium.' The propulsive effect of the cilia is modelled by a time-dependent force acting in a shear-thinned 'traction layer' between the mucus and the PCL. The effects of sur...

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...

Despite advances in the study of particle selection in suspension-feeding bivalves, the mechanisms upon which bivalves rely to discriminate among particles have not been elucidated. We hypothesized that particle sorting in suspension-feeding bivalves could be based, in part, on a biochemical recognition mechanism mediated by lectins within the mucus that covers the feeding organs. Using Crassos...

The distal colon functions as a bioreactor and harbors an enormous amount of bacteria in a mutualistic relationship with the host. The microbiota have to be kept at a safe distance to prevent inflammation, something that is achieved by a dense inner mucus layer that lines the epithelial cells. The large polymeric nets made up by the heavily O-glycosylated MUC2 mucin forms this physical barrier....

aloe buettneri a. berger is commonly used in traditional togolese medicine to treat inflammatory and gastric ulcers. the present study examined the gastro-protection effect of the hydro-alcoholic extract of a. buettneri on mucus production and gastric ph. a gastric ulcer is induced by ethanol 95° alone (1 ml/kg body weight), after pre-treatment with indomethacin (300 mg/kg) or by utilising l-na...

conclusions in japan, 8% lidocaine pump spray contains menthol and ethanol as additives. these additives, particularly menthol, might have led to excessive mucus production, although we did not analyze the mucus secretion. introduction pulmonary collapse after intubation is common, and it is caused by a variety of factors. case presentation a 21-year-old man presented at our operation room to u...

clomiphene citrate (cc) has an adverse effect on the quality and quantity of cervical mucus (cm). poor cervical mucus has been reported in 15% of cc-treated women. cc exhibits estrogen agonist and antagonist activities. antiestrogenic activity affecting the endocervical glands is theorized to cause a decrease in cervical mucus quality and quantity. an experimental study was performed to assess ...
