There has been no toxicologic proof that the long-term, low-level
exposure of man to chlorophenothane (DDT) is linked with an
increased susceptibility to toxicity or disease. Acute pretreatment
of rats with 75-100 mg/kg DDT has been demonstrated to potentiate
CCI₄-induced hepatotoxicity in that species (McLean and McLean,
1966). Since the...

Skeletal muscles provide several functions, including, yet not limited to, voluntary body movement and locomotion, posture and body position, and soft tissue support. Skeletal muscles also play a role in metabolism, requiring energy to facilitate contraction. Each skeletal muscle serves a different purpose despite seeming to perform the same task....
To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...
Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities and is an important threat to the zebrafish model. This microsporidian parasite can cause clinical disease, but more importantly is a causative agent of non-protocol induced variation in research. Studies utilizing infected zebrafish, could potentially confound...

Smoldering combustion in wildland fires is difficult to extinguish, can transition to flaming combustion, and produces a significant amount of pollutants. It is necessary to understand parameters controlling smoldering in order to help predict the smoldering behavior and potentially mitigate these hazards. The wide variety of natural fuels that occur...
Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...
