Detection of amblyopia utilizing generated retinal reflexes
Investigation confirmed that GRR images can be consistently obtained and that these images contain information required to detect the optical inequality of one eye compared to the fellow eye. Digital analyses, electro-optical analyses, and trained observers were used to evaluate the GRR images. Two and three dimensional plots were made from the digital analyses results. These plotted data greatly enhanced the GRR image content, and it was possible for nontrained observers to correctly identify normal vs abnormal ocular status by viewing the plots. Based upon the criteria of detecting equality or inequality of ocular status of a person's eyes, the trained observer correctly identified the ocular status of 90% of the 232 persons who participated in this program
Eating disorders in the time of COVID-19.
We have all been stunned by the speed of this viral pandemic. At the time of writing, one fifth of the world is under lockdown. The main foci have been on the public health effort to contain the spread of the virus, and the care of individuals with acute infection. We, in eating disorders, must have a broader brief. Not only must we help care for those sufferers who contract COVID-19, we must also address the impact-psychological, financial and social - on those that do not. The peculiarities of COVID-19 and the reaction of the public and governments to it, have particular relevance for people living with an eating disorder and those who care for them
Lax forms of the -Painlev\'e equations
All -Painlev\'e equations which are obtained from the -analog of the
sixth Painlev\'e equation are expressed in a Lax formalism. They are
characterized by the data of the associated linear -difference equations.
The degeneration pattern from the -Painlev\'e equation of type is also
presented.Comment: 24 page
Community-based trial of screening for Chlamydia trachomatis to prevent pelvic inflammatory disease: the POPI (prevention of pelvic infection) trial.
BACKGROUND: Pelvic inflammatory disease (PID) is common and can lead to tubal factor infertility, ectopic pregnancy or chronic pelvic pain. Despite major UK government investment in the National Chlamydia Screening Programme, evidence of benefit remains controversial. The main aim of this trial was to investigate whether screening and treatment of chlamydial infection reduced the incidence of PID over 12 months. Secondary aims were to conduct exploratory studies of the role of bacterial vaginosis (BV) in the development of PID and of the natural history of chlamydial infection.
DESIGN: Randomised controlled trial with follow up after 12 months.
SETTING NON-HEALTHCARE: Common rooms and lecture theatres at 20 universities and further education colleges in Greater London.
PARTICIPANTS: 2500 sexually active female students were asked to complete a questionnaire on sexual health and provide self-administered vaginal swabs and smears.
INTERVENTION: Vaginal swabs from intervention women were tested for chlamydia by polymerase chain reaction (PCR) and those infected referred for treatment. Vaginal swabs from control women were stored and analysed after a year. Vaginal smears were Gram stained and analysed for BV.
MAIN OUTCOME MEASURE: Incidence of clinical PID over 12 months in intervention and control groups. Possible cases of PID will be identified from questionnaires and record searches. Confirmation of the diagnosis will be done by detailed review of medical records by three independent researchers blind to whether the woman is in intervention or control group. TRIAL REGISTRATION: Clinical Trials NCT 00115388

Atomic Energy - Patents - Patent Aspects of Domestic Law, Euratom, and the International Atomic Energy Agency
With the growing importance of atomic energy, conventional legal concepts must be adapted and remodeled to fit new situations. In the area of patent law, the traditional notion that the inventor\u27s reward should be a legal monopoly in the invention, in the form of a patent, has to be reconciled with the need for wide dissemination of technical information. The need for secrecy, for government control over weapons, and for cooperation with other countries affects the atomic patent system. These factors are reflected in the Atomic Energy Act of 1954 and in the agreements establishing two international organizations concerned with atomic energy: the European Atomic Energy Community (EURATOM) and the International Atomic Energy Agency. It is the purpose of this comment to sketch some of these patent provisions
Dow Chemical vs. âCoercive Utopiansâ: Constructing the Contested Ground of Science and Government Regulation in 1970s America
In 1979, the Dow Chemical Company published an excerpt from a speech by H. Peter Metzger that announced an emerging conflict in American ideals and public policy. He stated that a new kind of individual inhabited Washington, people from the counterculture who were âcoercive utopiansâ because they sought to achieve their agenda through covert actions and hoped to end the American free market economy. Following the 1962 publication of Rachel Carsonâs Silent Spring and the subsequent banning of DDT in 1972, Dow and other chemical manufacturers fought to keep the regulatory climate favorable to industry. Dow found itself defending the phenoxy herbicide 2,4,5-T in particular for almost the entire decade of the 1970s. Using Dow Chemical Company records, trial transcripts, scientific journals, and writings by environmental activists, it becomes possible to see the contested landscape of scientific knowledge and chemical regulation. This essay argues that Metzger\u27s âcoercive utopiansâ challenged the assumed scientific basis of chemical safety and used the regulatory powers of the state to reassess the safety of everyday chemicals. This established a pattern of contested knowledge and ideological conflict that continues to form the core of debate between public safety and free-market prerogative
