OBJECTIVE To briefly review biochemical changes that may result from prolonged strenuous exercise and to relate these changes to health risk. METHODS Medline and Sports Discus databases were searched for relevant articles. Additional articles were found using cross referencing and the authors' knowledge of the subject area. RESULTS Prolonged strenuous exercise may result in a series of bioc...

In the context of several pathologies, the presence of lymphocytes has been correlated with disease outcome. The ability to automatically detect lymphocyte nuclei on histopathology imagery could potentially result in the development of an image based prognostic tool. In this paper we present a method based on the estimation of a mixture of Gaussians for determining the probability distribution ...

Changes in body posture, musculoskeletal disorders and somatic dysfunctions are frequently observed during pregnancy especially ligament, joint and myofascial impairment. The aim of the paper is to present the use of osteopathic manipulative treatment (OMT) for back and pelvic pain in pregnancy on the basis of a review of the available literature. MEDLINE and Cochrane Library were searched in J...

To determine whether Schistosoma mattheei is present in the south-western Transvaal, sixty habitats were searched for the intermediate host snail, Bulinus africanus. Ten populations of this snail were located, 2 of which were infected with S. mattheei. Eggs of one of these isolates, originating from a spring in the Mooi River, were examined with an optical microscope. Scanning electron microgra...

The Antibiotic Guide is a clinically oriented database developed by Johns Hopkins infectious disease and pharmacology personnel. It is described as a decision support tool for clinicians. The guide has two components: a main database of more than 160 antibiotics, which can be searched by entering a search term or by choosing a drug name, diagnosis or pathogen; and a feature area including news ...

This review looks at the role of an alkaline diet in health. Pubmed was searched looking for articles on pH, potential renal acid loads, bone health, muscle, growth hormone, back pain, vitamin D and chemotherapy. Many books written in the lay literature on the alkaline diet were also reviewed and evaluated in light of the published medical literature. There may be some value in considering an a...

This paper proposes a method for detecting known objects in 3D environments and estimating their positions with multiple pan-tilt-zoom cameras. Our search method, Dynamic Active Search, reduces the number of camera operations by predicting the existence of a target in wide angles, zooming-in a promising area, and confirming the target. Even when many reference images taken under various object ...

We present 1.4 GHz VLA observations of the variability of radio sources in the Lockman Hole region at the level of ≥ 100µJy on timescales of 17 months and 19 days. These data indicate that the areal density of highly variable sources at this level is < 5 × 10 −3 arcmin −2. We set an upper limit of 2% to the fraction of 50 to 100µJy sources that are highly variable (∆S ≥ 50%). These results impl...

Searching Twenty-three databases of published and grey literature were searched using a pre-specified search strategy. These sources included MEDLINE (from 1966 to October 1998), databases on BIDS (from 1981 to October 1998), EconLit (from 1969 to October 1998), EMBASE (from 1985 to October 1998), Cancerlit (from 1985 to October 1998), CINAHL (from 1982 to October 1998) and PsycINFO (from 1985 ...

Expert chess players, specialized in different openings, recalled positions and solved problems within and outside their area of specialization. While their general expertise was at a similar level, players performed better with stimuli from their area of specialization. The effect of specialization on both recall and problem solving was strong enough to override general expertise-players remem...
