Effect of satellite programming that is telecast to cable subscribers as perceived by public school liaisons.

In the late 1980\u27s and the early 1990\u27s the public perception of distance learning in many communities was manifested in a lack of community support and inadequate funding for educational satellite programs. Technological educational changes addressed major defects in the way information was transmitted to public schools. Satellites and cable technologies were available and affordable to serve as catalysts for positive educational results. Research indicated that the number of schools using satellite dishes to receive instructional programs had increased 87% during the 1992-1993 school year. Over one half of all public school students nationally attended schools where satellite technology was available. This dissertation entered upon research on the group of public school liaisons who provided educational satellite programming in their communities. A review of the literature showed a variety of models for staff development, teaching and community involvement that used satellite and cable. A questionnaire survey was conducted among a statewide group of satellite liaisons and provided the primary quantitative database for the study. The survey asked respondents about the use and coordination of satellite and cable at their institutions. The methodology also involved qualitative research in which respondents were queried about the perceptions of distance learning in their communities. This combination of the literature review and the survey results may serve as an informational guide for those communities and school districts not using this technology presently

Critical tonicity determination of sperm using fluorescent staining and flow cytometry

The use of cryopreserved, rather than fresh, mammalian semen for artificial insemination confers several important medical and/or economic advantages. However, current methods for cryopreservation of both human and bovine spermatozoa result in approximately only a 50% survival rate with thawing, obviously reducing the fertilizing capacity of the semen. A primary consideration during the cooling process is to avoid intracellular ice crystal formation with its lethal consequences to the cell. Current techniques achieve this by controlling the cooling rate. Computation of the time necessary for this dehydration, and hence, the cooling rate, is dependent upon knowledge of the water permeability coefficient (L{sub {rho}}) and its activation energy. The fluorophore, 6-carboxyfluoroscein diacetate (CFDA), which is nonfluorescent, readily crosses the intact plasma membrane. Intracellular esterases hydrolyze CFDA to 6-carboxyfluoroscein, a fluorescent, membrane-impermeable fluorophore. Consequently, spermatozoa with intact plasma membranes fluoresce bright green (Garner et. al., 1986), but those with disrupted membranes do not. Therefore, the purpose of this study was to use loss of CFDA fluorescence to determine the osmolality at which 50% of the spermatozoa will swell and lyse (critical tonicity, CT). These data will then be used to determine the L{sub {rho}} and its activation energy for sperm, thus increasing the knowledge available in cellular cryopreservation. 15 refs., 3 figs

Suppurative cribriform ulcers in one leg

An 89‐year‐old female presented with a 3‐year history of painless ulcers on right lower leg. Each lesion began as small nodules that gradually ulcerated and expanded (Figs. 1 and 2). She had similar ulcers on the same leg, which spontaneously healed over months in the past year. There was no preceding trauma or environmental water exposure. She denied fevers or systemic symptoms. Her past medical history is significant for ischemic heart disease, coronary arterial bypass, stroke, hypertension, and right lower limb venous insufficiency. Clinical examination revealed multiple superficial ulcers with an exudative base and surrounding erythema, distributed over her right distal leg from the mid shin to ankle with several erythematous nodules adjacent to the right knee. Angiotensin converting enzyme (ACE) levels, rheumatoid factor, and antineutrophil cytoplasmic antibodies were not raised. There was no hilar lymphadenopathy on chest radiography. Bone scan and Doppler ultrasonography excluded osteomyelitis and arterial disease, respectively. She reported no improvement after receiving multiple courses of antibiotic therapy. We performed multiple skin biopsies for histopathology and tissue culture (Figs. 3 and 4). Histopathology demonstrated a zone of dermal necrosis lined by granulomatous palisading epithelioid histiocytes with multinucleated giant cells undermining an acanthotic epidermis. The granulomatous reaction was associated with an inflammatory infiltrate of lymphocytes, neutrophils, and plasma cells. Special stains for organisms, including mycobacterial and fungi, were negative. Tissue cultures sent for atypical mycobacteria and fungi, as well as panmycobaterium DNA polymerase chain reaction, were negative on two separate occasions
