PURPOSE The purpose of this study was to evaluate the incidence of chronic knee changes in long-distance runners based on the training status, including distance, running frequency, training pace, and running experience. METHODS MRI of the knee was performed in 26 non-professional runners 5 days after their last training unit. Lesions of the menisci and cartilage (5-point scale), bone marrow ...

Introduction. A critical step for the in vitro engineering of a threedimensional tissue is to initially achieve a uniform distribution of cells seeded throughout the entire scaffold. Furthermore, if autologous cells are to be used in a clinical application, cells isolated from a small biopsy must be utilized with maximum efficiency. To overcome limitations associated with the most commonly empl...

The woollen coat, for example, which covers the day-labourer, as coarse and rough as it may appear, is the produce of the joint labour of a great multitude of workmen. The shepherd, the sorter of the wool, the wool-comber or carder, the dyer, the scribbler, the spinner, the weaver, the fuller, the dresser, with many others, must all join their different arts in order to complete even this homel...

We present a concept for a medium scale satellite mission to measurement the Bmode polarization in the CMB at large angular scales. The idea is to close pack a multifrequency array of ∼1500 corrugated feeds to make a “feed farm”. The majority point along the spin axis of the satellite. The primary modulation is obtained by spinning the satellite. Thus, in any instant the polarization in one dir...

A 55-year-old male runner was found to have severe three-vessel coronary disease on angiography soon after completing a 25-mile marathon with no symptoms. This patient raises important questions concerning our understanding of ischemic heart disease.

The purpose of this study was to compare the effects of bicycle seat tube angles (STA) of (72° and 82°) on power production and EMG of the vastus laeralis (VL), vastus medialis (VM), semimembranous (SM), biceps femoris (BF) during a Wingate test (WAT). Twelve experienced cyclists performed a WAT at each STA. Repeated measures ANOVA was used to identify differences in muscular activation by STA....
