Osteoprogenitor cells encapsulated in alginate and alternatively, additionally encapsulated in poly-L-lysine and/or agarose promote regeneration of bone at the site of implantation. The present invention provides a composition comprising osteoprogenitor cells embedded or encapsulated in alginate and the use of said microcapsules for the facilitation of bone regeneration.

A analytic bone implant includes a cylindrical housing with an inner chamber designed for collecting sample of bone tissues. The outer surface of the housing is provided with a plurality of threads for securing the implant into bone tissue. The housing is further provided with a plurality of openings to allow new bone tissue to grow into a collecting basket. The openings in the housing are alignable with complementary openings in the basket. The openings on the basket are provided with sharp edges which serve as cutting blades to facilitate the removal of the bone sample. The implant includes provision for repeated access to the medullary compartment for obtaining sample of cancellous tissue for histologic and morphometric analysis.

Analytic bone implant

A method for determining the pulse rate of a person. The method of the present invention is implemented in two phases. The first phase involes the determination of pulse intervals and the second phase provides an indication of the pulse rate based on the data produced during the first phase. The first phase is implemented by an algorithm which produces a pulse distribution profile from an array of pulses obtained from an appropriate transducer. In the second phase of the measurement, the distribution is searched to locate the region of maximum density. The pulse rate within the maximally dense region are then averaged to determine pulse rate. The pulse rate detection method of the present invention eliminates a significant number of erroneous pulse signals before calculation of pulse rate, thus providing a more accurate indication of the true pulse rate. The processing algorithm used in the preferred embodiment is based on an integer distribution the measurement can be obtained with a minimum amount of system memory and processor time.
