Priming grapevines with oregano essential oil vapour results in a metabolomic shift eliciting resistance against downy mildew.

Background: Priming plants with natural products is extensively studied in the agricultural field to reduce the use of synthetic and copper-based pesticides. Previous studies have shown that Oregano essential oil vapour (OEOV) is an effective priming agent against downy mildew (DM) in grapevine (Vitis vinifera L. cv.

Bascom Headen Palmer, Jr, MD (1889-1954).

Purpose: Most ophthalmologists in the United States recognize the name "Bascom Palmer" but few are familiar with the individual for whom the Eye Institute is named. This article reviews the biography of Bascom Headen Palmer, Jr, MD (1889-1954).

Electron diffraction of foam-like clusters between xenon and helium in superfluid helium droplets.

We report electron diffraction results of xenon clusters formed in superfluid helium droplets, with droplet sizes in the range of 105-106 atoms/droplet and xenon clusters from a few to a few hundred atoms. Under four different experimental conditions, the diffraction profiles can be fitted using four atom pairs of Xe. For the two experiments performed with higher helium contributions, the fittings with one pair of Xe-He and three pairs of Xe-Xe distances are statistically preferred compared with four pairs of Xe-Xe distances, while the other two experiments exhibit the opposite preference.

Semi-Autologous Corneal Transplantation with Simultaneous Bilateral Surgery: A Case Report.

The present report describes a case of semi-autologous corneal transplantation with bilateral surgery using two operating microscopes simultaneously. An 86-year-old man with history of six prior failed penetrating keratoplasties in his right eye presented with decreased vision. His other eye was deeply amblyopic but had a clear 30-year-old Castroviejo-square graft with an endothelial cell count of 803 cells/mm.
