Effects of local land-use on riparian vegetation, water quality, and the functional organization of macroinvertebrate assemblages.

Land-use change is a principal factor affecting riparian vegetation and river biodiversity. In Chile, land-use change has drastically intensified over the last decade, with native forests converted to exotic forest plantations and agricultural land. However, the effects thereof on aquatic ecosystems are not well understood.

Comprehensive Review of the ThinkFirst Injury Prevention Programs: A 30-Year Success Story for Organized Neurosurgery.

Traumatic brain and spinal cord injuries are major public health issues causing significant death and long-term disability in the United States, with higher incidences in young and older adults. The ThinkFirst National Injury Prevention Foundation is a nonprofit organization focused on injury prevention education and awareness for people of all ages, with a particular focus on educating children, teens, and young adults. ThinkFirst chapters have evaluated the effectiveness of the ThinkFirst programs in both children and teens by demonstrating significant improvement in knowledge regarding high-risk behaviors postintervention.

Isolation Driven Divergence in Osmoregulation in Galaxias maculatus (Jenyns, 1848) (Actinopterygii: Osmeriformes).

Background: Marine species have colonized extreme environments during evolution such as freshwater habitats. The amphidromous teleost fish, Galaxias maculatus is found mainly migrating between estuaries and rivers, but some landlocked populations have been described in lakes formed during the last deglaciation process in the Andes. In the present study we use mtDNA sequences to reconstruct the historical scenario of colonization of such a lake and evaluated the osmoregulatory shift associated to changes in habitat and life cycle between amphidromous and landlocked populations.

Clinical characterization and mutation spectrum in Caribbean Hispanic families with Lynch syndrome.

Lynch syndrome (LS) is an inherited form of colorectal cancer (CRC) caused by germline mutations in the mismatch repair (MMR) genes. It accounts for approximately 5% of all CRCs. The prevalence of LS among US Hispanics is unknown.

Heavy metals in the liver and muscle of Micropogonias manni fish from Budi Lake, Araucania Region, Chile: potential risk for humans.

The concentrations of cadmium, lead, manganese and zinc were determined in the fish species Micropogonias manni captured in Budi Lake, Araucanía Region (Chile). The measurements were made by atomic absorption spectroscopy, and the analysis considered the sex, weight and size of the species; the representative samples were taken from the liver and muscle tissue. The method was validated using certified reference material (DOLT-1).
