Testing the naked eye observation of the cervix after application of acetic acid as an effective screening test for cervical dysplasia

The Papanicolaou test is the recommended screening for cervical cancer. It has a high false-negative rate. Because of the imperfection of the Papanicolaou other screening tests have been developed. Five studies compared various aspects of different screening techniques with mixed results; A quasi-experimental design study was constructed comparing the naked eye observation of the cervix to the colposcopy observation, and the naked eye observation of the cervix to the Papanicolaou test; The sample of 136 women from the Las Vegas area, being seen at their regular clinics were examined with all three procedures. A physiologic framework directed this study. The research hypotheses included: (1) The naked eye observation of the cervix agrees with the colposcopy observation; (2) The naked eye observation of the cervix agrees with the Papanicolaou test; (3) The naked eye observation of the cervix increases detection of cervical dysplasia. Hypotheses 1 and 3 were accepted

A simple microbiological tool to evaluate the effect of environmental health interventions on hand contamination.

The effects of interventions such as sanitation or hand hygiene on hand contamination are difficult to evaluate. We explored the ability of a simple microbiological test to: (1) detect recontamination after handwashing; (2) reflect risk factors for microbial contamination and (3) be applicable to large populations. The study was done in rural Andhra Pradesh, India, and Maputo, Mozambique. Participants placed all 10 fingertips on a chromogenic agar that stains Enterococcus spp. and E. coli spp. Outcomes were the number of colonies and the number of fingertips with colonies. In the recontamination study, participants were randomised to handwashing with soap and no handwashing, and tested at 30 min intervals afterwards. In two cross sectional studies, risk factors for hand contamination were explored. Recontamination of hands after washing with soap was fast, with baseline levels reached after 1 h. Child care was associated with higher Enterococcus spp. counts, whereas agricultural activities increased E. coli spp. counts. Food preparation was associated with higher counts for both organisms. In Maputo, counts were not strongly associated with water access, latrine type, education or diarrhoea. The method seems unsuitable for the evaluation of handwashing promotion. It may reflect immediately preceding risk practices but not household-level risk factors

Expansion of the half retinal projection to the tectum in goldfish: An electrophysiological and Anatomical study

The topographical retino-tectal projection of goldfish was electrophysiologically mapped at various intervals after surgical removal of the nasal half of the retina and pigment epithelium. The remaining projection was initially restricted to the appropriate rostral half of the tectum, even if the nerve was crushed and allowed to regenerate. But later, after 137 days or more, it showed a progressive expansion onto the foreign caudal half of the tectum. The magnification factor, the number of micrometers of tectum per degree in the visual field, doubled in the rostro-caudal but not in the medio-lateral direction. Analysis of the sequence of the expansion showed that a few fibers originally projecting nearest the denervated area were the first to spread over it. Then, progressively more fibers moved caudally until a nearly uniform representation of the half retina was established on the tectum. Radioautography also demonstrated that retinal fiber terminals had invaded the caudal tectum. The retinae of these fish were also examined histologically. The density of ganglion cells had not increased, but they consistently showed the axonal reaction. This was not found to be associated with any initial surgical trauma, but rather with the movement of their fiber terminals within the tectum. Frozen sections, through half retinal and normal eyes, were cut and photographed for comparison of ocular geometry. Operated eyes were normal except for a slight but consistent loss of ocular volume. Analysis of the optical geometry showed that recording with fish in air produced two effects: Myopia (10° blur circle, or less) and enlargement of the visual field by 15% to 20%.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50003/1/901770206_ftp.pd

Nurturing at-risk students\u27 writing abilities

The purpose of this journal article was to review current professional literature on the writing process and the importance of voice in writing and then to design and implement a writing program for at-risk sixth grade students. The writing process is an effective means for children to create meaning, especially for at-risk students. In the writing process, the writer\u27s voice gives the best sense of a writer\u27s potential. This driving force was the basis of the instructional project in writing developed for at-risk sixth grade students

The Impact of Microenterprise Development Training on Low-Income Clients

The study reported here examined the impact of microenterprise development (MED) programs on low-income individuals using a case study of 140 clients of the Vermont Micro Business Development Program who participated in a statewide telephone survey. The study also examined variables that are associated with change in client reliance on public assistance. Outcomes achieved include: access to capital, positive attitude changes, business start up and growth, job creation, increased household income, decreased reliance on public assistance, and satisfaction with services. Significant relationships were found between certain client characteristics and outcomes and decreased reliance on public assistance

Use of Flow Cytometry and Stable Isotope Analysis to Determine Phytoplankton Uptake of Wastewater Derived Ammonium in a Nutrient-rich River

Anthropogenic alteration of the form and concentration of nitrogen (N) in aquatic ecosystems is widespread. Understanding availability and uptake of different N sources at the base of aquatic food webs is critical to establishment of effective nutrient management programs. Stable isotopes of N (14N,15N) are often used to trace the sources of N fuelling aquatic primary production, but effective use of this approach requires obtaining a reliable isotopic ratio for phytoplankton. In this study, we tested the use of flow cytometry to isolate phytoplankton from bulk particulate organic matter (POM) in a portion of the Sacramento River, California, during river-scale nutrient manipulation experiments that involved halting wastewater discharges high in ammonium (NH4 +). Field samples were collected using a Lagrangian approach, allowing us to measure changes in phytoplankton N source in the presence and absence of wastewater derived NH4 +. Comparison of δ15N-POM and δ15N-phytoplankton (δ15N-PHY) revealed that their δ15N values followed broadly similar trends. However, after 3 days of downstream travel in the presence of wastewater treatment plant (WWTP) effluent, δ15N-POM and δ15N-PHY in the Sacramento River differed by as much as 7‰. Using a stable isotope mixing model approach, we estimated that in the presence of effluent between 40 and 90% of phytoplankton-N was derived from NH4 + after 3 days of downstream transport. An apparent gradual increase over time in the proportion of NH4 + in the phytoplankton N pool suggests that either very low phytoplankton growth rates resulted in an N turnover time that exceeded the travel time sampled during this study, or a portion of the phytoplankton community continued to access nitrate even in the presence of elevated NH4 + concentrations
