The viscid exudate found on fronds o f the fern, Cheilanthes kaulfussii, consists of terpenoids in which flavonoid aglycones are dissolved. One of the terpenes is shown to be em-kaur-16-en-19-oic acid. The farinose frond exudate of Notholaena pallens contains this acid as the major constituent and its 3 /?-hydroxy derivative, together with flavonoid aglycones as minor components. In N. incana, ...

A 7-year-old horse was referred to the Veterinary Teaching Large Animal Hospital of Shiraz Veterinary School, Iran, with fever, dyspnea, tachypnea, cough and nasal discharge. Treatment with antibiotics and antihistamines was ineffective and the animal died 3 weeks post-admission. Post-mortem examination revealed bronchopneumonia with the presence of a large amount of fibrinopurulent exudate in ...

Effective management of wound exudate is key to promoting successful wound healing (White and Cutting, 2006). Wound exudate is produced in response to a complicated interaction between: wound aetiology, wound healing physiology, wound environment and compounding pathological processes (World Union of Wound Healing Societies [WUWHS], 2007). However, wound fluid is also known to assist healing by...

Traditional fluid handling data presented to clinicians attempts to demonstrate the ability of dressings to absorb and manage wound fluid in a clinical environment. However, little of the research available takes into account the variation in wound exudate presentation that a dressing would be expected to handle. The industry standard makes use of Solution A (142mmol sodium ions, 2.5mmol calciu...

Hagfish produce vast amounts of slime when under attack. The slime is the most dilute hydrogel known to date, and is a highly interesting material for biomaterial research. It forms from a glandular secrete, called exudate, which deploys upon contact with seawater. To study slime formation ex vivo and to characterize its material properties, stabilization of the sensitive slime exudate is cruci...

Burn wound exudate is an important source of information on the wound-healing process and systemic improvement of burn patients. Identification of biomarkers for the prediagnosis of local or systemic complications in patients will have a great impact on adapting personalized procedures in burn treatment. No efficient exudate collection method exists that offers a direct and continuous collectio...

Bacillus cereus UW85 suppresses diseases of alfalfa seedlings, although alfalfa seed exudate inhibits the growth of UW85 in culture (J. L. Milner, S. J. Raffel, B. J. Lethbridge, and J. Handelsman, Appl. Microbiol. Biotechnol. 43:685-691, 1995). In this study, we determined the chemical basis for and biological role of the inhibitory activity. All of the alfalfa germ plasm tested included seeds...

Stimulation of hatching of a tobacco cyst nematode (Globodera tabacum solanacearum) by root exudates from resistant NC 567 and susceptible K 326 cultivars of flue-cured tobacco, Nicotiana tabacum, was investigated. Root exudates were collected by soaking seedlings in deionized water for 2 hours at 22 degrees C in the dark. Fifteen mature and uniformly sized cysts were exposed at 15, 20, or 25 d...
