A broad comparative study of insect respiratory morphology is presented. Tracheae, epidermal invaginations extending into the body in branching networks tubes, supply tissues with direct access to air for gas exchange. While previous tracheal studies focused on a handful taxa and lacked consistency, here unified system nomenclature established using visualizations from micro-CT scanning represe...

I magine a three-dimensional city that is twelve times higher that the Great Pyramid of Giza in Egypt. It is the largest structure on the world and it floats over Tokyo Bay while being build largely by robots. It ...

OBJECTIVES The aims of this study were to: (1) determine the validity and reliability of the Nova Biomedical Lactate Plus portable analyzer, and quantify any fixed or proportional bias; (2) determine the effect of any bias on the determination of the lactate threshold and (3) determine the effect that blood sampling methods have on validity and reliability. DESIGN In this method comparison st...

BACKGROUND The purpose of this study was to test effects of negative pressure on tendon-bone healing after reconstruction of anterior cruciate ligament (ACL) in rabbits. METHODS Hind legs of 24 New Zealand White rabbits were randomly selected as negative pressure group and the contralateral hind legs as control. Reconstruction of the ACL was done. Joints of the negative pressure side were pla...

The increase in number of fine (< 0.5 mm diameter) roots of one-year-old clonal Pinus radiata D. Don trees grown in large open-top field chambers at ambient (362 micro mol mol(-1)) or elevated (654 micro mol mol(-1)) CO(2) concentration was estimated using minirhizotron tubes placed horizontally at a depth of 0.3 m. The trees were well supplied with water and nutrients. Destructive harvesting o...

OBJECTIVE To determine the efficacy of a non-invasive, manual soft-tissue physical therapy in opening completely blocked fallopian tubes in infertile women with confirmed bilateral occlusion and a history indicative of abdominopelvic adhesions. DESIGN Retrospective analysis. SETTING Clear Passage Therapies, Inc, clinic, Gainesville, Florida. PATIENTS 28 infertile women (mean age = 35.2) w...

Interference microscopy has enabled investigators to determine the weight of unstained and even living cells and cellular components by precise optical means and has also provided a direct image of structural details with excellent and control lable contrast and high resolution (Mellors 1957). By interference microscopy measurements of dry mass of genetic material in sperm nuclei of the mouse, ...
