Submerged macrophytes affect many aspects of lotic ecosystems, including nutrient dynamics. We performed longitudinal vegetation surveys to describe the distribution of macrophytes in Big Spring Creek, Wisconsin. We also ...

Abstract: A conserved [K/R]x[K/R] motif is found at the subunit-subunit interface in bacterial RecA protein filaments. In the Escherichia coli RecA protein, this motif is made up of residues K248 and K250. Both of these ...

Many large- and small-scale changes occur in the genomes of tumor cells. The optical mapping system was used previously to discover structural variations (OSAs; Optical Structural Alterations) in tumor genomes. OSAs are ...

Through previous studies, it has been found that Zebrafish embryos show a predictable pattern of cell division consisting of the spindle apparatus always aligning perpendicular to its orientation in the previous cell stage. ...

Development of residential lakeshore properties can have several effects on aquatic ecosystems including the thinning of littoral coarse woody habitat. Previous studies have shown that reduction of littoral coarse woody ...

Mothers of many species find great comfort in their offspring, which in turn has been found to alleviate mild stress in the mother. In the face of a life-threatening event, however, do offspring still act as effective ...

Calorie Restriction (CR) without malnutrition extends mean and maximal lifespan in multiple species, although the mechanism is unknown. CR has a dramatic effect on adipose tissue morphology, gene expression and energy ...

Vitamin D (1,25 D3) is an important transcriptional regulator of many genes including our gene of interest, osteopontin. Osteopontin is a known regulator of bone calcification and mineralization and is involved in signaling ...

Mutated SETX, a human gene encoding for the protein Senataxin, has been identified among patients with two different neurodegenerative disorders--ataxia-ocular apraxia 2 (AOA2) and amyotrophic lateral sclerosis 4 (ALS4). ...

Our previous studies demonstrated that anti-CD40 mAb (anti-CD40) can synergize with CpG oligodeoxynucleotides (CpG) to mediate antitumor effects by activating myeloid cells such as macro phages in tumor-bearing mice. ...
