The international reference system for beta-particle emitting radionuclides: Validation through the pilot study CCRI(II)-P1.Co-60.

The Bureau International des Poids et Mesures (BIPM) is developing a new transfer instrument to extend its centralized services for assessing the international equivalence of radioactive standards to new radionuclides. A liquid scintillation counter using the triple/double coincidence ratio method is being studied and tested in the CCRI(II)-P1.Co-60 pilot study.

A high-resolution radiation hybrid map of the human genome draft sequence.

We have constructed a physical map of the human genome by using a panel of 90 whole-genome radiation hybrids (the TNG panel) in conjunction with 40,322 sequence-tagged sites (STSs) derived from random genomic sequences as well as expressed sequences. Of 36,678 STSs on the TNG radiation hybrid map, only 3604 (9.8%) were absent from the unassembled draft sequence of the human genome.

Acute bereavement services and routine referral as a mechanism to increase donation.

Efforts to develop a mechanism that improves donation rates and provides better service to patients and staff are presented in this article. The University of Nebraska Medical Center has incorporated a routine referral process into its acute bereavement services requiring representatives to respond to each in-house death to provide consistent support and management for the decedent's family and the hospital staff. Every family was offered bereavement support and the opportunity to consent to autopsy as well as to organ and tissue donation if medically appropriate.

Board certification in health psychology.

As professional practice in health psychology has matured, mechanisms for board certification through the American Board of Professional Psychology have been developed. This article describes the American Board of Health Psychology and its role in the credentialing of practitioners who demonstrate advanced competence in the science and practice of psychology related to health, including the prevention, treatment, and rehabilitation of illness.
