HD Physiology Project-Japanese efforts to promote multilevel integrative systems biology and physiome research.

The HD Physiology Project is a Japanese research consortium that aimed to develop methods and a computational platform in which physiological and pathological information can be described in high-level definitions across multiple scales of time and size. During the 5 years of this project, an appropriate software platform for multilevel functional simulation was developed and a whole-heart model including pharmacokinetics for the assessment of the proarrhythmic risk of drugs was developed. In this article, we outline the description and scientific strategy of this project and present the achievements and influence on multilevel integrative systems biology and physiome research

Dwarf Peppers: Evaluation of ‘Triton’

In November, 2001 through a connection with Mary Musgrave at University of Massachusetts, the sweet pepper ‘Triton’ was identified. ‘Triton’ is only 20-cm tall, flowers in 25 days, and produces large (~5 to 8 cm long) fruit. We are now characterizing the yield and environmental response of ‘Triton’. Additionally, seed will be collected from mature fruit and will be included in our dwarf seed outreach program run primarily though our web page. We are attempting to find the genetic origin of ‘Triton’

The Relationship between Apelin and Angiotensin II in Paroxysmal Supraventricular Tachycardia

Background: We aimed to investigate apelin and angiotensin II serum levels in patient whit paroxysmal supraventricular tachycardia. Methods: This was a cross-sectional study on 38 patients with paroxysmal supraventricular tachycardia (PSVT), and 38 age- and sex-matched healthy individuals. Blood samples were taken from these people, and angiotensin II/apelin levels were measured using enzyme-linked immunosorbent assay (ELISA). To analyze the data, descriptive statistics were used. Results: Apelin levels were lower in PSVT group compared to control group; but the difference was not significant (P = 0.302). Angiotensin II levels were significantly lower in PSVT groups compared to controls (P = 0.003). Conclusion: Like similar studies, this study showed that apelin serum levels were lower in PSVT groups, but this difference was not significant. However, mean serum levels of angiotensin II was significantly lower in PSVT groups. This could be due to the consumption of calcium blockers in these patients.

Factors associated with student grades in Animal Physiology I

Students and faculty alike would like to know what factors are related to success in college courses. The purpose of this study was to evaluate factors that relate to a student’s success in Animal Physiology I (Phys I), an upper-level animal science course at the University of Arkansas. Student data were confidentially collected and coded. Data collected were student high school grade point average (HSGPA); composite ACT score; English, reading, math, and science subscores on the ACT; and student grades in English composition I and II, college algebra, chemistry, biology, microbiology, animal physiology II, and reproductive physiology. Prematriculation performance confirmed that students with higher HSGPA and (or) ACT scores had better grades in animal physiology I. However, ACT subscores were not more informative than the ACT composite score. Performance in prerequisite courses (chemistry and biology) was significantly related to student grades in Animal Physiology I. Student grades in related courses indicated the same results, that is, students that do well in high school tend to have better grades in college, including in Animal Physiology I

Historical Summary of the Selection of USU-Perigee

USU-Apogee was back-crossed with line 3-2-3 in 1999 to get an improved super dwarf wheat. Sixty-eight seeds were planted from the F1 generation. This table summarizes the two year selection process from F2 to F10 generations. USU-Perigee is the same height as Super-Dwarf but yields 30% better

Physiology of man and animals in the Tenth Five-Year Plan: Proceedings of the Thirteenth Congress of the I. P. Pavlov All-Union Physiological Society

Research in the field of animal and human physiology is reviewed. The following topics on problems of physiological science and related fields of knowledge are discussed: neurophysiology and higher nervous activity, physiology of sensory systems, physiology of visceral systems, evolutionary and ecological physiology, physiological cybernetics, computer application in physiology, information support of physiological research, history and theory of development of physiology. Also discussed were: artificial intelligence, physiological problems of reflex therapy, correlation of structure and function of the brain, adaptation and activity, microcirculation, and physiological studies in nerve and mental diseases

Update on male reproductive endocrinology.

Practitioners of male reproductive and sexual medicine must have an intimate understanding of the physiology of male reproductive endocrinology, as such a knowledge is the cornerstone on which hormonal treatments are based. In this review, we highlight what is known about male reproductive endocrine physiology and the various control mechanisms for the system. We also discuss the limitations of our current understanding of the reproductive physiology. We hope that this review is helpful for male reproductive medicine practitioners in understanding the principles on which hormonal treatments are based

The attachment system and physiology in adulthood: normative processes, individual differences, and implications for health.

Attachment theory provides a conceptual framework for understanding intersections between personality and close relationships in adulthood. Moreover, attachment has implications for stress-related physiology and physical health. We review work on normative processes and individual differences in the attachment behavioral system, as well as their associations with biological mechanisms related to health outcomes. We highlight the need for more basic research on normative processes and physiology and discuss our own research on individual differences in attachment and links with physiology. We then describe a novel perspective on attachment and physiology, wherein stress-related physiological changes may also be viewed as supporting the social-cognitive and emotion regulatory functions of the attachment system through providing additional energy to the brain, which has implications for eating behavior and health. We close by discussing our work on individual differences in attachment and restorative processes, including sleep and skin repair, and by stressing the importance of developing biologically plausible models for describing how attachment may impact chronic illness
