Changing refractive outcomes with increasing astigmatism at longer-term follow-up for infant cataract surgery.

PurposeTo present longer-term refractive and ocular health outcomes for patients who had primary intraocular lens (IOL) insertion following infant cataract surgery.Patients and methodsA retrospective review of all infant cataract cases at a tertiary children's hospital between 2003 and 2006 was conducted. Surgery was performed before 12 months of age.

Algal biofuels from urban wastewaters: maximizing biomass yield using nutrients recycled from hydrothermal processing of biomass.

Recent studies have proposed algal cultivation in urban wastewaters for the dual purpose of waste treatment and bioenergy production from the resulting biomass. This study proposes an enhancement to this approach that integrates cultivation of an acidophilic strain, Galdieria sulphuraria 5587.1, in a closed photobioreactor (PBR); hydrothermal liquefaction (HTL) of the wet algal biomass; and recirculation of the nutrient-rich aqueous product (AP) of HTL to the PBR to achieve higher biomass productivity than that could be achieved with raw wastewater.
