Background: Little is known about mechanisms of genetic influence on panic, particularly in childhood. Cognitive theories of panic disorder highlight threatening interpretations of physical sensations, and increased awareness of such sensations. Specifically, anxiety sensitivity (AS) and heartbeat perception (HBP) have been associated with panic…

A considerable body of evidence obtained from studies of children who are deaf and who use cochlear implants has been useful in guiding practices that lead to higher levels of English language proficiency and age-appropriate literacy. Both (a) research conducted at implant centers and (b) educational programs with significant numbers of children…

The ability to recognize and appreciate from a reproductive standpoint that males and females possess different attributes has been long standing. Only more recently have we begun to look more deeply into both the similarities and differences between men and women, as well as between boys and girls, with respect to the structure and function of…

A vital and productive society with a prosperous and sustainable future is built on a foundation of healthy child development. Health in the earliest years--beginning with the future mother's well-being before she becomes pregnant--lays the groundwork for a lifetime of vitality. When developing biological systems are strengthened by positive early…

Teachers represent the largest group of occupational voice users and have voice-related problems at a rate of over twice that found in the general population. Among teachers, music teachers are roughly four times more likely than classroom teachers to develop voice-related problems. Although it has been established that music teachers use their…

Catechol-O-methyltransferase (COMT) is a methylation enzyme that catalyzes the degradation pathway and inactivation of dopamine. It is accepted widely as being involved in the modulation of dopaminergic physiology and prefrontal cortex (PFC) function. The COMT Val158Met polymorphism is associated with variation in COMT activity. COMT 158Met allele…

The differential results obtained when the perceived exertion levels of 19 high-fit and 17 low-fit women were assessed according to Borg's Rating of Perceived Exertion Scale and magnitude estimation suggests that the RPE scaling procedures may be tapping a very select component of the perceptual process. These results do indicate that the scaling…

This investigation sought to determine whether the excellent performer evolves from typical material through training or if he brings facilitating characteristics with him to practice on the first day. Subjects were highly successful AAU age-group competitors who had invested at least 50 percent of their lives in swim training. These seven female…

Describes a computer program allowing students to study such circulatory variables as venus return, cardiac output, mean circulatory filling pressure, resistance to venous return, and equilibrium point. Documentation for this Applesoft program (or diskette) is available from author. (JM)

Author provided a brief series of exercises designed to promote flexibility for students learning modern dance and suitable for the limited space of most classrooms. (Author/RK)

A study attempted to determine whether force and duration parameters are programmed in an interactive or independent fashion prior to executing ballistic type isometric contractions of graded intensities. Four adult females each performed 360 trials of producing ballistic type forces representing 25, 40, 55, and 75 percent of their maximal…

This study reexamined the concept that delayed muscle soreness (DMS) is a form of inflammatory pain. This was accomplished by having 32 male volunteers perform exercise known to induce DMS and then assess the total and differential white blood cell changes. In addition, an anti-inflammatory drug, idomethacin, was administered to determine whether…

New systems for analyzing large numbers of body fluid components can be used in the clinical laboratory. (Author/RH)

This round-table discussion focuses on the pros and cons of biking as a means to physical fitness and offers practical tips for beginning cyclists. (JS)
