Some say that science is an art, a craft, and a passion-and, one may add these days, often also a business [...

Subthreshold nanosecond laser therapy for chronic central serous chorioretinopathy: A prospective study.

Purpose: To investigate the morphologic and functional outcomes of nanosecond subthreshold (ST) laser treatment for patients with chronic central serous chorioretinopathy (CSC).

Methods: In this prospective study, 44 patients were treated with the ST nanosecond laser with a follow-up period of 12 months. All target variables were measured at 1, 3, 6 and 12 months after the first laser treatment.

Selenium Disulfide from Sustainable Resources: An Example of "Redneck" Chemistry with a Pinch of Salt.

Selenium disulfide (often referred to as SeS) encompasses a family of mixed selenium-sulfide eight-membered rings, traditionally used as an anti-dandruff agent in shampoos. SeS can be produced by reacting hydrogen sulfide (HS) with selenite (SeO) under acidic conditions. This chemistry is also possible with natural spring waters that are rich in HS, thus providing an avenue for the more sustainable, green production of high-quality SeS particles from an abundant natural source.
