peritoneally or intrapleurally into mice or patients bearing cancerous effusions remains largely local ized in the cavity and therefore can be used suc cessfully for intracavitary tumor therapy. Later (3, 9, 10), similar intracavitary retention of radio active material, suggesting analogous therapeutic application, was obtained with particle suspen sions of radioactive chromic phosphate (CrP320...

Crystal structure determination of macromolecules is often hampered by the lack of crystals suitable for diffraction experiments. This article describes a protocol to crystallize the acidic protein bovine -lactoglobulin in the presence of yttrium to yield high-quality crystals that belong to a new space group. The yttrium ions not only are used to engineer the crystallization, but are an integr...

Introduction: The use of lasers for treatment has become a common phenomenon in the medical field. Currently, numerous laser systems are available for dental use. The use of lasers for periodontal treatment becomes more complicated because the periodontium consists of both hard and soft tissues. Methods: Related articles were gathered and selected carefully and reviewed. Among the many lasers a...
