PURPOSE To determine population age norms in the first three years of life for binocular and monocular grating visual acuity (VA) obtained with Vistech-Teller Acuity Cards (TAC). METHODS TAC was used to estimate grating acuity in 646 healthy infants and children born at due date +/- 2 weeks, all of whom underwent ophthalmologic and orthoptic evaluation. The sample consisted of 20 age groups f...

For routine behavioral tasks, mice predominantly rely on olfactory cues and tactile information. In contrast, their visual capabilities appear rather restricted, raising the question whether they can improve if vision gets more behaviorally relevant. We therefore performed long-term training using the visual water task (VWT): adult standard cage (SC)-raised mice were trained to swim toward a re...

This is an a posteriori analysis of previously published data to assess whether improving vitamin A (VA) status resolves measles-related pneumonia (MP). Nonhospitalized acute measles patients (2 d of rash onset) had their VA status determined based on the molar ratio of retinol-binding protein to transthyretin (RBP/TTR). Using a cutoff value of </=0.36, indicative of marginal VA deficiency, 82 ...

Greenhouse gases released by human activities are the dominant forcing in anomalously high latter twentieth century temperatures in the Northern Hemisphere, overriding a millennial-scale cooling trend due to astronomical forcing (Briffa et al., 1995; Mann et al., 1998). At northern high latitudes this results in winter and spring warming accompanied Institute of Arctic Biology, University of Al...

BACKGROUND Many veterans have dual Veterans Administration (VA) and Medicare healthcare coverage. We compared 3-year overall and cancer event-free survival (EFS) among patients with nonmetastatic colon cancer who obtained substantial portions of their care in both systems and those whose care was obtained predominantly in the VA or in the Medicare fee-for-service system. METHODS We conducted ...

purpose: to assess the efficacy of polyhexamethylene biguanide (phmb) in treating acanthamoeba keratitis (ak) and also to identify related factors affecting final visual outcome in ak patients treated with phmb methods: in these interventional case series study, 27 eyes of 25 patients with ak received phmb 0.02% and divided into two groups according to the final visual acuity (va) va equal to o...
