Examination of low-incidence brain tumor responses in F344 rats following chemical exposures in National Toxicology Program carcinogenicity studies.

R C Sills et al.

Toxicologic pathology, 27(5), 589-599 (1999-10-21)

Neoplasms in the brain are uncommon in control Fischer 344 (F344) rats; they occur at a rate of less than 1% in 2-yr toxicity/carcinogenicity studies. Furthermore, only 10 of nearly 500 studies conducted by the National Toxicology Program (NTP) showed

Atmospheric oxidation mechanism of bromoethane.

Mónica Martínez-Avilés et al.

The journal of physical chemistry. A, 111(45), 11652-11660 (2007-10-19)

A mechanism for the atmospheric oxidation of bromoethane is proposed from an ab initio study. Using CCSD(T)/6-311++G(2df,2p)//MP2/6-31G(d) level of theory, the structure and energetics of the 35 species and transition states involved in the atmospheric oxidation of bromoethane are examined.

Release of apical dominance in potato tuber is accompanied by programmed cell death in the apical bud meristem.

Paula Teper-Bamnolker et al.

Plant physiology, 158(4), 2053-2067 (2012-03-01)

Potato (Solanum tuberosum) tuber, a swollen underground stem, is used as a model system for the study of dormancy release and sprouting. Natural dormancy release, at room temperature, is initiated by tuber apical bud meristem (TAB-meristem) sprouting characterized by apical
