Laser ablation therapy: An alternative treatment for medically resistant mesial temporal lobe epilepsy after age 50.

Selective anterior mesial temporal lobe (AMTL) resection is considered a safe and effective treatment for medically refractory mesial temporal lobe epilepsy (MTLE). However, as with any open surgical procedure, older patients (aged 50+) face greater risks. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) has shown recent potential as an alternative treatment for MTLE.

Population dynamics of the rat Microryzomys minutus (Rodentia: Muridae) in the Venezuelan Andes.

The population dynamics of the small forest rice rat Microryzomys minutus, a murid rodent that occurs in the high altitudes of the northern and central Andes, was studied in disturbed and primary environments in a cloud forest of the Venezuelan Andes (Juan Pablo Peñaloza National Park, 8 degrees 11'N, 71 degrees 49'W). We collected 121 animals (66 female female and 55 male male) between 1995 and 1998, using pitfall traps with formalin. Adult males were heavier than adult females.
