Ocular Damage Index, Ocular Pain and Subjective Visual Rating in Patients with Behçet's Uveitis: A Study of Impact on Health-Related Quality of Life.

Purpose: The aim of our study is to assess subjective disease burden parameters (SVR and OP) as well as objective ones (BCVA and ODI) as predictors of HRQoL in Egyptian patients with BD uveitis.

Methods: Ninety-six patients with BD uveitis were recruited in this cross-sectional study from the Rheumatology Department, Cairo University Hospital. HRQoL was assessed using RAND-36 item health survey 1.

Impact of exposure to arsenic on the bacterial microbiota associated with river biofilms in the Pampas region.

Freshwater contamination by arsenic (As) is a worldwide problem. It may be found in Pampean streams of Argentina at concentrations higher than those recommended by international organizations and stipulated by national regulations. Exposure to high As concentrations causes serious consequences to both human health and the environment.

Occurrence and accumulation of pharmaceutical products in water and biota of urban lowland rivers.

We evaluated the distribution of eleven groups of pharmaceutically active compounds (PhACs) in surface waters and biota of different trophic levels, in five sites of two lowland urban rivers in Argentine. Twenty-nine out of 39 PhACs and two metabolites were detected in at least one water sample (2-9622 ng/L), eleven detected in biofilms (1-179 ng/g d.w) and eight in the macrophyte Lemna gibba (4-112 ng/g d.

Evaluation of the Acute Effects of Arsenic on Adults of the Neotropical Native Fish Cnesterodon decemmaculatus Using a Set of Biomarkers.

Neotropical fish Cnesterodon decemmaculatus were exposed to different sublethal concentrations (0.5, 1.0 and 5.

Acute toxicity of cadmium to freshwater fishes and its relationship with body size and respiratory strategy.

Acute toxicity assays in freshwater fishes are used in diverse local and regional regulations. Lethality is a complex biological process, depending on both extrinsic and intrinsic factors. The extrinsic parameters (pH, temperature, hardness and alkalinity, among others) have been widely studied and their influence on toxicity has been well characterized.
