Article Synopsis
- Human activities are putting aquatic habitats at significant risk, notably affecting anadromous fish species like salmon and trout; improving freshwater habitats is crucial for their survival.
- A study conducted in lowland rivers examined the impact of the aquatic plant Ranunculus on juvenile Atlantic salmon and brown trout by manipulating its cover in various sites over two years.
- Results showed that increased Ranunculus cover led to higher abundance, growth, and retention of salmon, while also promoting better foraging conditions and reducing competition between trout and salmon.
Systematic Analysis of the Relative Abundance of Polymers Occurring as Microplastics in Freshwaters and Estuaries.

Despite growing interest in the environmental impact of microplastics, a standardized characterization method is not available. We carried out a systematic analysis of reliable global data detailing the relative abundance of polymers in freshwaters and estuaries. The polymers were identified according to seven main categories: polyethylene terephthalate, polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyurethane and a final category of miscellaneous plastic.

This study compared the clinical utility of serum myoglobin (S-Mgb) in conjunction with the ratio of S-Mgb to CA-III (S-Mgb/CA-III) versus creatine kinase-MB (CK-MB) for the early diagnosis of acute myocardial infarction (AMI).
Methods: This prospective observational study set at a university teaching hospital emergency department enrolled 251 consecutive consenting patients who presented with symptoms consistent with cardiac ischemia or infarction of less than 12 hours' duration.
Study Objective: To compare the predictive values of serum myoglobin and creatine kinase (CK)-MB for ruling out acute myocardial infarction in the emergency department.
Design: Prospective, observational study.
Setting: University teaching hospital.
"Abnormal" electrocardiograms are found in 56% to 84% of patients with cocaine-associated chest pain. This study was designed to assess whether these findings can be explained by "normal" variations in young patients' electrocardiograms. This cross-sectional study was conducted in a municipal hospital emergency department and walk-in clinic.
