BACKGROUND/AIMS Povidone-iodine (PVP -I) is applied for microbial decontamination of human eyes donated for transplantation. Concentrations and immersion times vary greatly. The effectiveness and toxicity of PVP-I were assessed for different decontamination protocols. METHODS Human donor eyes and corneas were immersed in different concentrations (5-100 mg/ml) of PVP-I for different times (2-3...

0. Introduction. Minimal immersions from a Riemann surface M into Sn were studied by Calabi ([3]) and Chern ([4]), among many authors. To such an immesion F in S4, they found a holomorphic quartic form QF (to be defined in Section 1) on M . A superminimal immersion is one for which QF = 0, which is always the case when M = S 2. In [2], Bryant studied a superminimal immersion of a higher genus i...

A previously reported procedure for the introduction of Borrelia spirochetes into tick larvae by immersion in a suspension of spirochetes was tested on Ixodes ricinus (L.) ticks and three of the most medically important European Borrelia genomic species, B. burgdorferi sensu stricto, B. garinii and B. afzelii. The procedure was compared with "classical" infection of nymphs by feeding on infecte...

Thiazolidinediones cause sodium retention and edema by a direct effect on the kidneys. The aim of this study was to use the technique of head-out water immersion to investigate the effects of rosiglitazone on sodium and volume homeostasis in subjects with type 2 diabetes mellitus. The volume expansion response to water immersion was compared with the response on a non-immersion control day in 1...

The objectives of this experimental, randomized, controlled trial study were to evaluate the effect of immersion baths on the length of the first stage of childbirth labor and on the frequency and length of the uterine contractions. Data were collected in a philanthropic public maternity hospital of the city of São Paulo whose month average is 1,100 births. The sample was comprised of 108 women...

The resolution of an optical microscope is restricted by the diffraction limit, which is approximately 200 nm for a white light source. We report that sub-diffraction-limited objects can be resolved in immersion liquids using a microsphere optical nanoscopy (MONS) technique. Image magnifications and resolutions were obtained experimentally and compared in different immersion liquids. We show th...

An important question for ecologically valid virtual environments is whether cohort characteristics affect immersion. If a method for assessing a certain neurocognitive capacity (e.g. attentional processing) is adapted to a cohort other than the one that was used for the initial normative distribution, data obtained in the new cohort may not be reflective of the neurocognitive capacity in quest...
