Long-term oral administration of sodium warfarin significantly reduced the incidence of spontaneous metastases in the lungs from 83 percent in controls to 8 percent in treated C57/BL/6N mice. The size and weight of primary tumors in mice treated with warfarin were less than in control mice. Length of survival was unaffected.

Bose-Chaudhuri-Hocquenghem and Justesen codes are used to pack equa spheres in M-dimensional Euclidean space with density A satisfying log2 A > — 6n + o(ri), for all sufficiently large n of the form m2, where m is a power of 4. These appear to be the densest packings yet constructed in high dimensional space.

Diet-induced obesity (DIO) in C57BL/6 mice is the standard model for studying obesity in mice. The few reports of DIO utilizing voluntary running provide contradictory results with respect to prevention of obesity. However, total energy expenditures associated with voluntary running during DIO are unknown. We hypothesized that voluntary running would increase the amount of total energy expended...

BACKGROUND Several prospective cohort and case-control studies reported the inconsistent association between biospecimen composition of C20 and C22 long-chain (LC) n-3 polyunsaturated fatty acid (PUFA) and colorectal cancer (CRC) risk. The aim of the present study was to investigate the association of biospecimen LC n-3 PUFA with CRC risk based on prospective cohort and case-control studies. ...

Background Circulating long-chain (LC) n-3 polyunsaturated fatty acid (PUFA) can provide objective measures that reflect both dietary consumption and relevant biological processes. Nevertheless, prospective cohort studies on circulating LC n-3 PUFA in relation to incidence of stroke have yielded inconsistent results. We therefore conducted a meta-analysis to quantitatively evaluate the associat...

The role of dynorphin/kappa opioid receptors in epilepsy and addiction are well accepted, but their function in emotional control is not yet fully understood. Data obtained from different strains of prodynorphin (Pdyn)- and kappa opioid receptor (KOP)-deficient mice do not provide a consistent picture of the functions of Dyn/KOP in anxiety, suggesting the influence of testing conditions and/or ...
