The group concluded that the research productivity of a dental school depended to a large extent on the availability of resources, human and economic. Firstly it requires a group of individuals ...trained and educated to conduct independent research. Secondly, it requires that these individuals had time to spend on research activities. Thirdly, appropriate space and equipment in which to conduct the research were considered prerequisites. Fourthly, they require an ongoing and appropriate budget. Fifthly, it is essential to have an appropriate climate in the school that encourages and rewards research achievement.

The Genographic Project is an international effort using genetic data to chart human migratory history. The project is non-profit and non-medical, and through its Legacy Fund supports locally led ...efforts to preserve indigenous and traditional cultures. In its second phase, the project is focusing on markers from across the entire genome to obtain a more complete understanding of human genetic variation. Although many commercial arrays exist for genome-wide SNP genotyping, they were designed for medical genetic studies and contain medically related markers that are not appropriate for global population genetic studies. GenoChip, the Genographic Project's new genotyping array, was designed to resolve these issues and enable higher-resolution research into outstanding questions in genetic anthropology. We developed novel methods to identify AIMs and genomic regions that may be enriched with alleles shared with ancestral hominins. Overall, we collected and ascertained AIMs from over 450 populations. Containing an unprecedented number of Y-chromosomal and mtDNA SNPs and over 130,000 SNPs from the autosomes and X-chromosome, the chip was carefully vetted to avoid inclusion of medically relevant markers. The GenoChip results were successfully validated. To demonstrate its capabilities, we compared the FST distributions of GenoChip SNPs to those of two commercial arrays for three continental populations. While all arrays yielded similarly shaped (inverse J) FST distributions, the GenoChip autosomal and X-chromosomal distributions had the highest mean FST, attesting to its ability to discern subpopulations. The GenoChip is a dedicated genotyping platform for genetic anthropology and promises to be the most powerful tool available for assessing population structure and migration history.
Speech is the prototypical, usually preferred, communication mode for humans. Recent progress in digitally processing and transporting human speech, in synthesizing speech from text, and in automatic ...recognition of human speech, promises improvements in both human-to-human and human-to-machine communication. We examine the roles of the human factors specialist, applied psychologist, and linguist, in developing and deploying these new technologies, and in constructing human-to-machine interfaces particularly suitable for speech input/output.
Two hundred and fifty-eight patients with small cell carcinoma and 185 patients with adenocarcinoma were centrally randomized to receive either cyclophosphamide (1000 mg/m2 every 3 weeks) iv or ...cyclophosphamide (700 mg/m2 every 3 weeks) iv plus CCNU (70 mg/m2 every 6 weeks) orally. Those patients who were initially treated with the single agent were then treated with CCNU (130 mg/m2 every 6 weeks) at the time of cyclophosphamide failure. Objective tumor regression occurred more frequently with the combination regimen in patients with small cell carcinoma (43% vs 22%, P = 0.002), but no difference in response rates was apparent in patients with adenocarcinoma. In both cell types patients survived somewhat longer following treatment with the combination. The overall incidence of severe toxicity was equal for the two regimens in both cell types; however, the therapeutic index of the combination was superior to that of the single agent in small cell carcinoma. Severe drug toxicity was more frequent in small cell carcinoma patients with extensive disease, and survival was reduced in both cell types with extensive disease. Survival was better for ambulatory patients in both cell types and women survived longer than men. In women with small cell carcinoma, ambulatory status also was associated with a higher incidence of tumor regression. In patients with small cell carcinoma those who had prior lung surgery survived longer than those without prior surgery. Previous radiation therapy was associated with a reduced incidence of objective regression in men with small cell carcinoma. In both cell types patients with tumor regression lived longer than nonresponders; however, objective disease stability was associated with improved survival only in patients with adenocarcinoma. Stratification in future studies should consider extent of disease, performance status, sex, and prior therapy.
