Large-scale semi-arid afforestation can enhance precipitation and carbon sequestration potential.

Afforestation is an important approach to mitigate global warming. Its complex interactions with the climate system, however, makes it controversial. Afforestation is expected to be effective in the tropics where biogeochemical and biogeophysical effects act in concert; however, its potential in the large semi-arid regions remains insufficiently explored.

Corneal endothelial morphologic features in toxic anterior segment syndrome.

Purpose: To investigate the clinical and laboratory findings of toxic anterior segment syndrome (TASS) following cataract surgery with intraocular lens (IOL) implantation, with emphasis on the morphologic features of the corneal endothelium.

Methods: A single-center retrospective observational case-control design was used. The sample consisted of 15 patients (mean age 60.

Endothelial cell loss during pterygium surgery: importance of timing of mitomycin C application.

Purpose: To determine if the timing of mitomycin C (MMC) application during pterygium surgery affects endothelial cell loss.

Methods: A retrospective, nonrandomized, case-series design was used. The study group included 40 patients who underwent pterygium surgery with the bare sclera technique.

Bilateral primary pterygia: an occupational disease?

The authors report on a case of bilateral pterygia that the Israeli Social Security Service acknowledged to be an occupational disease. The question of whether certain occupations are risk factors for pterygia has important medico-legal implications. The authors sought to shed more light on this issue through a case report of bilateral simultaneous pterygia in an Israeli tennis instructor and through a literature review.
