An unusual erythrocyte carbonic anhydrase C type isozyme tentatively designated as H has been found in American Negroes. It has an electrophoretic mobility near that of carbonic anhydrase B. In about 18% of the individuals studied the H isozyme replaces half of the normal C isozyme, and in about 1% of this population only the H isozyme is present.This work was supported in part by Grant CA-01786 from the United States Public Health Service.

This article explores links between disease and social standing in a primitive New Guinea community. Social and cultural events have modified the incidence of certain diseases. Furthermore, the changing patterns of disease may have influenced the development and form of social distinctions.This work is based on data collected as a predoctoral fellow in the Department of Anthropology at Columbia University. Fieldwork in New Guinea was done with NIH support under Training Grant 1 T01-MH11775-01 (related to 2 F1 MH301640-02), with Dr. Margaret Mead as the sponsor. Additional funding for analysis of data was obtained from the Harvard School of Public Health, the Department of Preventive Medicine of the Harvard Medical School, and the Institute for Transcultural Studies in New York.  相似文献

Starch gel electrophoresis has shown that natural populations of Fundulus heteroclitus have variants at four enzyme-coding loci: Idh-A, Idh-B, 6-Pgdh-A, and Est-S. Analysis of the phenotypic distribution of the F1 generation suggests that each of the variants segregates as autosomally inherited codominant alleles. Tissue specificity and intracellular localization were also determined for the IDH and 6PGDH isozymes.This work was supported by Grants DEB 76-19877 and DEB 79-12216 from the National Science Foundation and by Grant P60-80-04 from the State of Maryland.

Coordinating behavior is widespread in contexts that include courtship, aggression, and cooperation for shared outcomes. The social significance of cooperative coordination (CC) is usually downplayed by learning theorists, evolutionary biologists, and game theorists in favor of an individual behavior → outcome perspective predicated on maximizing payoffs for all participants. To more closely model CC as it occurs under free-ranging conditions, pairs of rats were rewarded for coordinated shuttling within a shared chamber with unrestricted social interaction. Results show that animals learned to work together with sensitivity to the task and type of partner. Moreover, social interaction and coordination influenced both consumption of the reward solution immediately following a session and preference for cooperation, suggesting that affective states and incentives related to cooperation extend beyond the outcomes obtained. These results support field studies by showing not only how cooperation is performed but also the importance of considering how the behavior of cooperating affects outcomes and preference for cooperating.

Diagnostic ultrasound came to Yale in the 1960s and was first developed in Glasgow and London. This story tells us that ultrasound was well-established in the Department of Obstetrics and Gynecology at Yale University School of Medicine in the Yale-New Haven Hospital by 1970. By then it had caught up with the pioneers in New York, Denver, and even Glasgow.  相似文献

Summary Using operant conditioning methods, the pigeon's wavelength discrimination abilities were assessed in two experiments to generate discrimination functions. Both these functions showed three minima at 460, 530 and 595 nm. In the second wavelength discrimination experiment, extending measurements into the UV spectral region, pigeons also maintained good discrimination between wavelengths within the UV range tested. A fourth minimum was indicated at the lower end of the spectral range tested (365–385 nm). The results point to the complexity of the pigeon's chromatic system, which must be at least tetrachromatic, probably pentachromatic.Abbreviations S+ positive stimulus - S– negative stimulus We thank the technical staff of the Psychology Department at Durham University for their assistance and. in particular, Mr. D.

Selection pressure from health risk is hypothesized to have shaped adaptations motivating individuals to attempt to become valued by other individuals by generously and recurrently providing beneficial goods and/or services to them because this strategy encouraged beneficiaries to provide costly health care to their benefactors when the latter were sick or injured. Additionally, adaptations are hypothesized to have co-evolved that motivate individuals to attend to and value those who recurrently provide them with important benefits so they are willing in turn to provide costly care when a valued person is disabled or in dire need. Individuals in egalitarian foraging bands can provide a number of valuable benefits, such as defense, diplomacy, food, healing, information, technical skill, or trading savvy. We therefore expect that humans have evolved psychological mechanisms motivating the pursuit and cultivation of a difficult-to-replace social role based on the provisioning of a benefit that confers a fitness advantage on its recipients. We call this phenomenon social niche specialization. One such niche that has been well-documented is meat-sharing. Here we present cross-cultural evidence that individuals cultivate two other niches, information and tool production, that serve (among other things) to buffer health risk.

To assess the relative contribution of specific and nonspecific effects of skin temperature biofeedback upon migraine headache, 11 migraine patients were taught to increase the temperature of their hand. Training to decrease the skin temperature of the hand served as a control for 12 other migraine patients. An additional 11 control subjects were not trained but kept records of migraine activity. Under carefully controlled double-blind procedures, migraine patients who learned to raise finger temperatures showed statistically significant and clinically therapeutic improvement during a 6-week follow-up period. However, they were not significantly better than those trained to lower finger temperatures, those who did not meet a learning criterion, or those receiving no training. While these groups did show some significant improvement when compared to subjects who learned to decrease finger temperature, the results are most parsimoniously explained through nonspecific rather than specific factors. The necessity of using double-blind procedures in evaluating therapeutic effectiveness is again stressed.This article was presented as a Citation Award Paper at the Biofeedback Society of America meetings, San Diego, 1979.

In two discrimination training studies, we noted improvements in the ability of healthy individuals to discriminate between respiratory sensations. We trained individuals to discriminate between respiratory sensations elicited during inspiration in Experiment 1 and during expiration in Experiment 2. We elicited respiratory sensations by having participants breathe through circuits that differed in their resistance to air flow. Training, in both experiments, was conducted within the context of a task in which individuals judged which member of a series of respiratory circuit pairs was easier to breathe through. To improve the accuracy of judgments, we gave participants feedback of their performance, and we faded air flow resistance. The latter procedure consisted of presenting circuit pairs in order of increasing similarity. Individuals who received performance feedback with fading of air flow resistance demonstrated reliable improvements in discrimination from pre- to posttraining in both experiments, but controls, who received either performance feedback or practice in discrimination did not. These findings may contribute to improving awareness of respiratory sensations in asthma patients, and thereby bolster efforts to manage asthma.This research was supported by a Biomedical Research Support Grant from the National Institute of Health to Ohio University and by an Academic Challenge Grant from the State of Ohio to the Ohio University Psychology Department.  相似文献

The Annual Spring workshop of the HUPO-PSI was this year held at the EMBL International Centre for Advanced Training (EICAT) in Heidelberg, Germany. Delegates briefly reviewed the successes of the group to date. These include the wide spread implementation of the molecular interaction data exchange formats, PSI-MI XML2.5 and MITAB, and also of mzML, the standard output format for mass spectrometer output data. These successes have resulted in enhanced accessibility to published data, for example the development of the PSICQUIC common query interface for interaction data and the development of databases such as PRIDE to act as public repositories for proteomics data and increased biosharing, through the development of consortia, for example IMEx and ProteomeXchange which will both share the burden of curating the increasing amounts of data being published and work together to make this more accessible to the bench scientist. Work then started over the three days of the workshop, with a focus on advancing the draft format for handling quantitative mass spectrometry data (mzQuantML) and further developing TraML, a standardized format for the exchange and transmission of transition lists for SRM experiments.  相似文献

Recently, there has been renewed interest in the organization and neurobiology of remote memory, and the pace of work in this area has accelerated. Yet the recent literature does not suggest that a consensus is developing, and there is disagreement about both facts and their interpretation. This article undertakes a comprehensive review of the three kinds of evidence that have been most prominent in recent discussion: studies of retrograde amnesia in memory-impaired patients who have well-characterized lesions, neuroimaging of healthy volunteers, and work with experimental animals including lesion studies, imaging and mouse genetics. The available evidence tells a coherent story and leads to some straightforward conclusions about the neuroscience of remote memory.  相似文献

The spatial variation in gene frequencies of four unlinked polymorphic loci was studied in the teleost Fundulus heteroclitus. Three loci (Idh-A, Idh-B, and Est-S) exhibit significant north-south clinal variation in allelic frequencies along the Atlantic Coast of North America, while a fourth locus (6-Pgdh-A) shows a modest clinal variation. These data, together with our previous data for Ldh-B, Mdh-A, Gpi-B, and Pgm-A, reveal a pattern of low gene diversity in the colder northern extremes of the species range and high gene diversity in warmer southern latitudes.This work was supported by Grants DEB76-19877 and DEB79-12216 from the National Science Foundation and by Grant P60-80-04 from the State of Maryland.

At the gene locus for liver alcohol dehydrogenase (ADH) of the Japanese quail, three alleles which give electrophoretic variants, A, B, and C, exist. This enzyme is autosomally inherited. Allelic polymorphism was not observed in the chicken, but the wild-type ADH of the chicken can readily be distinguished from A, B, and C of the quail by starch gel electrophoresis. In the development of both species, ADH activity reached a near adult level at about the nineteenth day (a few days after hatching in the quail and a few days before hatching in the chicken). Chicken-quail hybrids at the day of hatching (nineteenth day) revealed the presence of maternally derived quail ADH only, and their ADH activities were about half that of both parental species. Those hybrids which received either A or C allele from the mother quail showed three bands of ADH at the third day after hatching. The chicken and quail alleles began to function in synchronous harmony. One 3-day-old and two adult hybrids which received B allele from the quail, however, still revealed complete absence of the paternally derived chicken ADH.This work was supported in part by a grant (CA-05138) from the National Cancer Institute, U.S. Public Health Service, and in part by a research fund established in honor of General James H.

This paper is one of a series of papers in which I consider contemporary Yale medical education in general and the Yale Department of Epidemiology and Public Health in particular. It tells of the retirement in 1945 of C.-E.A. Winslow, Professor and Chairman of the Yale Department of Public Health since its inception in 1915; of the committees established by the dean of the School of Medicine and the president of the University, charged with determining the future direction of the department; and of the outcome, which, in 1945, proved favorable to Winslow's public health philosophy in contrast to the medical school's clinical needs and desires.  相似文献
