Yeast DNA replication.

We have explored various strategies for exploiting the yeast genetic and biochemical system for understanding DNA replication. Because of the long time that has intervened between the isolation of random replication mutants of yeast and the identification of the gene products affected, an alternative approach to elucidating the molecular basis of replication has been needed. One such alternative involves purifying replication proteins, isolating the genes encoding them, and constructing the appropriate mutant from the cloned gene. We have applied this "reverse genetics" strategy to three different replication activities: DNA polymerases, single-stranded DNA binding proteins, and proteins that bind to autonomously replicating sequence (ARS) elements.

The teaching of ethics in the dental hygiene curriculum.

This study describes the extent of formal instruction in ethics in dental hygiene programs. Responses from 159 programs indicated that all hygiene programs include ethics in the curriculum, but the method of teaching and the amount of time devoted to the subject varied considerably. The majority of programs included ethics as a component of a larger course such as dental hygiene practice or as a separate course in ethics and jurisprudence. Although most course instructors used the lecture format, most programs combined lecture with more active forms of learning, such as use of ethical dilemmas. In general, respondents felt satisfied with the current role of ethics in the dental hygiene curriculum, although there was some concern about their own competence in teaching the subject.

The location of eggs retained in the oviducts of mares.

The oviducts of 24 mares were examined to determine the site of retention of unfertilized eggs. The ampullary-isthmic junction regions of 42 of the 48 oviducts were serially sectioned and examined histologically. The remaining parts of the oviducts were flushed and the flushings searched microscopically. Of 45 eggs located, 40 were in the sectioned segments of 24 oviducts and only 5 were in the flushings. All but one of the sectioned segments contained prominent masses of material obstructing the lumen, but these were apparently not the direct cause of egg retention since eggs were found on both sides of them.

A community health center dental program in Boston, U.S.A.

In 1970, a community-based and federally funded dental program was established in Boston. The multiple objectives of this program included the following: provision of dental treatment; education of schoolchildren in dental health; support for community measures of prevention such as water fluoridation; support of job training programs in dental assisting for community residents; employment of community people; and sensitization and training in community health for dental students and auxiliaries. The program provided a number of dental services at a reasonable benefit-cost ratio of 0.87. Other endeavors included the development of a dental health program with community schools and the involvement of dental students in the delivery of care and in screening for children with dental treatment needs.

The status of community advisory committees in dental education.

A questionnaire survey was undertaken to determine how prevalent community advisory committees have become in the nation's dental schools and what types of committees have been formed. Responses were received from 52 (90 percent) of the 58 dental schools. The data revealed the following: 1. Nine schools (17 percent) have developed consumer committees. 2. The number of committee members varies from five to 29. 3. All the committees are composed of consumer members and school representatives, and, in all but one committee, health care providers are represented. 4. Four (44 percent) committees have advisory functions only, while the remaining five (56 percent) play an advisory and policy-making role. 5. No committee planned formal training sessions for their consumer members. 6. Of the 43 schools (83 percent) without such a committee, seven (16 percent) replied they foresee implementing a consumer committee in the future.

A comprehensive approach to dental health in a school population.

A program to provide school children with dental health education and preventive services was initiated by the Boston University School of Graduate Dentistry. This program utilized several generally untapped resources. The emphasis was on classroom education using teachers who were motivated by special workshops as well as students of dental auxiliary training programs. These dental auxiliary students under the supervision of a dental health educator were used to educate the classroom teachers as well as to teach children in the classroom. Direct dental services were also provided in the program in the form of preventive services utilizing an unused dental chair available at a school.
