Ninety eyes of 90 individuals presenting consecutively to a tertiary referral uveitis service with active toxoplasmic retinochoroiditis and gradable SD-OCT scans were evaluated prospectively.

Comprehensive in silico analysis and molecular dynamics of the superoxide dismutase 1 (SOD1) variants related to amyotrophic lateral sclerosis.

Amyotrophic Lateral Sclerosis (ALS) is the most frequent motor neuron disorder, with a significant social and economic burden. ALS remains incurable, and the only drugs approved for its treatments confers a survival benefit of a few months for the patients. Missense mutations in superoxide dismutase 1 (SOD1), a major cytoplasmic antioxidant enzyme, has been associated with ALS development, accounting for 23% of its familial cases and 7% of all sporadic cases.

Real effluents and fractionation in the supply of COD: Rapid adaptation and high efficiency to treat mine drainage combined with industrial by-products.

The biological treatment of mine drainage (MD) using sulfate-reducing bacteria (SRB) is a technology in growing exploitation. The use of by-products as sources of electrons can make this treatment more environmentally and economically advantageous. However, the high chemical oxygen demand (COD) and the presence of recalcitrant molecules can lead to the accumulation of metabolic intermediates that acidify the system, thus interrupting the treatment.

Frequency and visual outcomes of ocular toxoplasmosis in an adult Brazilian population.

Although ocular toxoplasmosis is a leading cause of posterior uveitis worldwide, there is scarce information about the real-life frequency of ocular lesions, visual outcomes, and risk factors for poor prognosis. We conducted a community-based cross-sectional study with 721 adults living in Cássia dos Coqueiros, Southeast Brazil, consisted of visual acuity measurement, dilated ocular examination, a risk-factor questionnaire, and peripheral blood collection for anti-T. gondii serology.
