The literature on root exudate is replete with studies of factors influencing the quantity and cycle of its production. For the most part, this work has been done utilizing herbaceous species or vines, but citations are also available on some of the broad-leaved trees. Root exudate from conifers is rarely reported, but in the course of preparation of a thesis at the University of California it ...

purpose: to report a relatively rare case of familial exudative vitreoretinopathy (fevr). patient and findings: a 13-year-old boy referred with decreased visual acuity of both eyes, specially right eye from 6 years ago. he had several ophthalmologist and optometrist visits and spectacle prescription without any improvement of vision. best corrected visual acuity (bcva) was 25 cm of count finger...

With the advances in the computer field, methods and techniques in automatic image processing and analysis provide the opportunity to detect automatically the change and degeneration in retinal images. Localization of the optic disc is extremely important for determining the hard exudate lesions or neovascularization, which is the later phase of diabetic retinopathy, in computer aided eye disea...

Determining the pH values of microscopic plant samples may help to explain complex processes in plants, so it is an area of interest to botanists. Fiber-optic probes with small dimensions can be used for this purpose. This paper deals with the fiber-optic detection of the pH values of droplets of plant xylem exudate based on ratiometric fluorescence intensity measurements with an internal refer...

The experiments reported above give evidence that in unresolved lobar pneumonia, the persistence of the exudate, followed by organization, depends upon the presence of serum in the exudate.

BACKGROUND A relatively new technology in wound care, negative pressure wound therapy (NPWT), has become widely used for the management of open abdomens and soft tissue wounds and provides a means to collect wound exudate to quantify protein loss. METHODS A prospective observational study was conducted in surgical, trauma, or burn patients (8 patients with open abdomens and 9 patients with ac...

The hydrogen ion concentration in the lesions of experimental pneumococcus infection has been estimated directly by pH determinations on exudates from living animals. For indirect evidence of an increase in hydrogen ion concentration within the lesions, the difference in sugar content between exudate and blood from animals with pneumococcus infection has been measured. With sanguinous exudate f...

Abstract Detection of the optic disc which has similar brightness with hard and soft exudate lesions seen in early stage diabetic retinopathy is very difficult due to different light conditions contrast values. Automatic detection these by expert systems medical field important. In this context, we propose a new approach based on analysis color spaces, keypoint detectors, texture for retinal fu...

Bud exudates from twelve clones o f Populus nigra originating from seven countries were analyzed by gas chromatography-mass spectrometry and the principal compounds identified. Specimens o f P. nigra var betulifolia differed in bud exudate composition from the other speci­ mens analyzed, and were more similar in exudate composition to P. deltoides than were the other specimens. The range o f bu...
