Disc-fovea Angle Is Associated With Visual Field Defect Location in Patients With Glaucoma.

Precis: The current study showed that glaucomatous eyes from patients with central visual field defects presented less negative disc-fovea angle compared with patients with peripheral defects.

Purpose: The purpose of this study was to investigate the relationship between disc-fovea angle and visual field defect location in patients with glaucoma.

Materials And Methods: This was a cross-sectional study including glaucoma patients divided into isolated central and isolated peripheral scotoma groups.

The effects of local ischemic preconditioning and topical hypothermia in renal ischemia/reperfusion injury in rats.

Purpose: Topical hypothermia and local ischemic preconditioning have been shown to reduce renal ischemia-reperfusion (I/R) injury individually. We examined whether combination of both strategies lessens renal I/R injury.

Methods: Post right nephrectomy, 40 male Wistar rats were randomly assigned to five experimental protocols performed in the left kidney: topical hypothermia without ischemia (TH), warm ischemia (IR), ischemic preconditioning followed by warm ischemia (IPC+IR), cold ischemia (TH+IR), and ischemic preconditioning followed by cold ischemia (IPC+TH+IR).

Archeometric studies in the Franciscan Convent of "Santo Antônio" (Recife, PE).

The purpose of this paper is to characterize the tiles placed on the walls of the Franciscan convent of "Santo Antônio" (Recife-PE) and to obtain information about the several expansions and structural reforms performed on the convent by dating the bricks. For this purpose, a portable energy dispersive x-ray fluorescence (EDXRF) was used to characterize the tiles. The dating of the bricks was performed using the Thermoluminescence (TL) technique.
