Increased metabolic demand reveals morpho-functional impacts caused by settleable atmospheric particulate matter on fish gills.

Department of Physiological Sciences, Federal University of São Carlos, São Carlos, SP, Brazil.
Exposure to environmentally relevant levels of settleable atmospheric particulate matter (SePM) limits the aerobic performance of inactive healthy adult fish. We evaluated the gill morpho-functional impacts (gill structure and ionic balance) caused by SePM exposure (96 h) in Nile tilapia when fish is impelled to maximal aerobic swimming effort. In control fish, swimming reduced epithelial filament thickness (EFT, 25 %), increased the distance between lamellae (DL, 21 %), and reduced the plasma Na (5 %).

Department of Orthodontics, The University of Texas Health Science Center at Houston School of Dentistry, Houston, Texas.
Background: This study aimed to compare the soft tissue effects of Herbst appliance in Class II malocclusion patients treated in three different craniofacial growth phases: prepubertal (PRE), circumpubertal (CIR), and postpubertal (POS).
Methods: In total, 95 patients with Class II Division 1 malocclusion previously treated with a Herbst appliance were analyzed. Through the cervical vertebral maturation stages method, patients were allocated into three groups depending on the growth craniofacial phase at the beginning of treatment: PRE, CIR, and POS.

Changes in environmental conditions in aquatic ecosystems caused by anthropic actions can modify the composition of primary producers, promoting the excessive proliferation of cyanobacteria. These organisms can form cyanobacterial blooms, which directly affect aquatic life. The present study investigated the mutagenicity of the cyanobacterium Sphaerospermopsis torques-reginae (strain ITEP-024), guanitoxin-producing (natural organophosphate), and sublethal effects on fish in relevant environment concentrations.

February 2019
Departmento de Química Física, Facultad de Ciencias del Mar y Ambientales, Universidad de Cádiz, Puerto Real, Spain; Department of Ecotoxicology, University of Santa Cecilia, Santos, Sao Paulo, Brazil.
Article Synopsis
- The study evaluates sediment quality in the Guadalquivir River between Alcalá del Río and Seville, focusing on contamination and toxicity using the Asiatic clam as a bioindicator.
- This research employs a range of biomarkers to identify the adverse effects of sediment contamination from various human activities, revealing significant biological stress from metal(loid)s, especially near Seville.
- Findings suggest that the biomarker approach effectively highlights contamination impacts, with evidence that as exposure levels peak, the clams' detoxification abilities decline, indicating a deterioration in sediment quality.

Lasers Med Sci
January 2013
Department of Endodontics, University of Santa Cecília, São Paulo, Brazil.
Different treatments of dentin walls, as laser irradiation, prior to obturation can influence the adhesion ability of endodontic sealers. Therefore, the objective of this study was to compare in vitro the shear bond strength of four resin-based sealers to dentin treated with citric acid solution or erbium: yttrium, aluminum, garnet (Er:YAG) irradiation. A total of 240 slices with 1.
