    Notes: The thermal expansion coefficients along the a axis (αa) and c axis (αc) of barium hexaferrite were measured from room temperature to 850 °C. The thermal expansion of barium hexaferrite along the a axis and c axis was found to be linear as a function of temperature, indicating constant thermal expansion coefficients over this temperature range. The specific values for αc and αa were calculated to be 12.2±0.9 and 9.99±1.1 ppm/°C, respectively. The measurements were performed using a standard x-ray powder diffraction setup equipped with a high temperature stage. © 1996 American Institute of Physics.

    Notes: 1. Drugs acting within the autonomic nervous system (ANS) are of particular interest when autonomic abnormalities are implicated in the development and maintenance of various cardiovascular pathologies. For example, it has been documented that in the early stages of hypertensive disease (i.e. hyperkinetic borderline hypertension) a sympathetic hyperactivity associated with a decreased parasympathetic activity results in increased cardiac output and heart rate.2. Several classes of drugs acting within the central, as well as the peripheral ANS, are very efficient in treating hypertensive disease. One of these classes of drugs, the second generation of centrally acting drugs, has proved beneficial in this respect because, in addition to their therapeutic efficacy, these drugs are well tolerated.3. The central nervous system may also be the target for drugs with the potential to treat other cardiovascular diseases. Some recent experimental and clinical data supporting such new perspectives concerning idiopathic dysrhythmias, angina pectoris and congestive heart failure will be summarized.

    An improved Moser-Aubin-Onofri inequality for axially symmetric functions on $S^2$ (1998)

    Notes: Abstract. We show that for some $\alpha$ , ${1\over 2}\leq \alpha 〈{16 \over 25}$ , the following inequality holds: \[ {\alpha\over 2}\int_{-1}^1 (1-x^2)|g'(x)|^2 dx + \int_{-1}^1 g(x) dx - \ln{{1}\over{2}}\int_{-1}^1 e^{2g(x)} dx \geq 0, \] for every function $g$ on $(-1,1)$ satisfying $\|g\|^2 = \int_{-1}^1(1-x^2)|g'(x)|^2 dx 〈\infty$ and $ \int_{-1}^1 e^{2g(x)} x dx = 0$ . This improves a result of Chang and Yang [C-Y2] in the axially symmetric case.

    Analysis of frequency (frq) clock gene homologs: evidence for a helix-turn-helix transcription factor (1997)

    Notes: Abstract The frq gene plays a key role in the organization of the Neurospora crassa circadian clock. Our previous analysis of a C-terminal fragment of the putative FRQ protein suggested it is a nuclear transcription factor but did not identify a known DNA-binding domain. If the hypothesis is correct that FRQ is a transcription factor, sequences consistent with this function should be conserved in distantly related species. To investigate, we have cloned frq homologs from other filamentous fungi including Chromocrea spinulosa, and Leptosphaeria australiensis. Alignment of the Leptosphaeria and Chromocrea proteins with the published (complete) sequences for Neurospora crassa and Sordaria fimicola shows that they are respectively about 47% and 43% identical to both Neurospora and Sordaria. The alignment identifies several short regions of high conservation punctuated by regions showing near total divergence. Sequences consistent with FRQ being a transcription factor are generally conserved. Most importantly, we show that a highly conserved segment of the protein has strongly predicted helix-turn-helix (HTH) structure as supported by three independent methods. Further, this segment shows the defining sequence characteristics of known HTH DNA-binding domains. Amino acids at positions altered in frq mutant alleles are conserved in all species examined. Transformation of the Neurosporafrq 9(conditionally arrhythmic) mutant with the Chromocrea homolog rescued the pigmentation and conidiation defects of the mutant but not the circadian defect; the Leptosphaeria homolog failed to rescue any defect. Together, these data provide the first testable hypotheses concerning several specific aspects of FRQ structure and function.

    Health-related quality of life of HIV-infected women: evidence for the reliability, validity and responsiveness of the Medical Outcomes Study Short-Form 20 (1996)

    Notes: Abstract The purpose of this study was to assess the reliability, validity and responsiveness of a health-related quality of life (HRQOL) instrument, the Medical Outcomes Short-Form 20-ltem General Health Survey (MOS SF-20), in a sample of women with the human immunodeficiency virus (HIV). Longitudinal data were collected on 202 HIV-infected women without AIDS who were receiving care at Kings County Hospital or SUNY Health Sciences Center, Brooklyn, New York. Internal consistency results showed acceptable reliability for the four multi-item MOS scales (role function, physical function, general health perceptions and mental health). Symptomatic patients and patients with lower Karnofsky Performance Status (KPS) ratings reported lower HRQOL than those who were asymptomatic or who had higher KPS scores. Patients who were older, unemployed or who had a history of injection drug use (IDU) also reported lower HRQOL. than those who were younger, employed or who had no drug use history. Adjusted mean scores on the MOS role and physical functioning scales proved sensitive to differences in clinical status over time. The MOS SF-20 is a reliable and valid instrument of HRQOL for women with HIV infection. Its sensitivity to differences in clinical status over time suggest that it may be useful as an HRQOL indicator for HIV/AIDS clinical trials.
