Ralph Steinman is to receive the 2007 Albert Lasker Award for Basic Medical Research for his discovery of dendritic cells and his path-breaking work demonstrating their central role as the principal antigen-presenting cells of the immune system and key activators of T cell responses.

a total of 68385 live pin-worm eggs from adhesive scotch tape were exposed to different detergent powders in under to compare method of detergent washing clothes with the boiling method for the control of family enterobiasis. results show that: a) 80.4-100 percent of eggs are destroyed after hatching within 6-8 hours of exposure to 0.25 gr% detergent at 10-250c. exposure for less than 6 hours h...

Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...

By R. DOROTHY SUNDBERG, PH.D., AND RUTH E. HODGSON, M.S. I NTEREST in obtaining specimens of bone marrow comparable to those aspirated from the human sternum, ilium, or spinous process caused us to devise a technic which we feel is both simple and reliable. Many similar technics have been described, but most of them have not attained wide usage because they have required minor surgical operatio...

Prostatic intra-epithelial neoplasia (PIN) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. In this study, we applied the PIN grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of...

A lthough the key principles of external fixation have changed little over the years, there remains a significant amount of variation in fixation methods and postoperative care. In particular, use and management of halfpins intended for prolonged reconstruction are the subject of strong opinions and intense debate. Half-pins are commonly available in stainless steel and titanium. They are also ...

The tracheal epithelium of the rodent is a simple columnar ciliated type composed of ciliated cells, goblet cells, nonciliated columnar cells, brush cells, and basal cells. The noncillatcd cells are concells have been described in detail (Rhodin and Dalhamn, 1956; Rhodin, 1966; Leeson, 1961; Cireli, 1966; Steinman, 1968), the three-dimensional construction of the tracheal epithelimn has never b...

In navigated total hip arthroplasty, the pelvis and the femur are tracked by means of rigid bodies fixed directly to the bones. Exact tracking throughout the procedure requires that the connection between the marker and bone remains stable in terms of translation and rotation. We carried out a cadaver study to compare the intra-operative stability of markers consisting of an anchoring screw wit...
