Three new phenylpropanoid glycosides, named luteoside A (3), luteoside B (4), and luteoside C (5), were isolated together with the known compounds verbascoside (1) and isoverbascoside (2) from the roots of the medicinal plant Markhamia lutea. The structures of the new compounds were determined to be 1-O-(3, 4-dihydroxyphenyl)ethyl(More)
The authors analyzed data from the Framingham Heart Study to evaluate the association between physical activity and breast cancer risk. Physical activity was ascertained by a physician-administered questionnaire from 2,321 women at the fourth biennial examination conducted in 1954-1956. Breast cancers were identified by self-report, surveillance of(More)
BACKGROUND People with intellectual disability (ID) and epilepsy are more likely to die prematurely than the general population. A significant number of deaths in people with epilepsy may be potentially preventable through better seizure control, regular monitoring and raising awareness among patients and carers. The aim of this project was to study(More)
We observe a new D_{s} meson with mass (2856.6+/-1.5_{stat}+/-5.0_{syst}) MeV/c;{2} and width (48+/-7_{stat}+/-10_{syst}) MeV/c;{2} decaying into D0K+ and D;{+}K_{S};{0}. In the same mass distributions, we also observe a broad structure with mass (2688+/-4_{stat}+/-3_{syst}) MeV/c;{2} and width (112+/-7_{stat}+/-36_{syst}) MeV/c;{2}. To obtain this result,(More)
We study initial-state radiation events, e+ e- --> gammaISR pi+ pi- J/psi, with data collected with the BABAR detector. We observe an accumulation of events near 4.26 GeV/c2 in the invariant-mass spectrum of pi+ pi- J/psi. Fits to the mass spectrum indicate that a broad resonance with a mass of about 4.26 GeV/c2 is required to describe the observed(More)
The nitrite reductase (nirS and nirK) and nitrous oxide reductase-encoding (nosZ) genes of denitrifying populations present in an agricultural grassland soil were quantified using real-time polymerase chain reaction (PCR) assays. Samples from three separate pedological depths at the chosen site were investigated: horizon A (0-10 cm), horizon B (45-55 cm),(More)
BACKGROUND The purpose of this work was to determine the efficacy of inhibiting mammalian target of rapamycin (mTOR) in pancreatic cancer preclinical models and translate preclinical observations to the clinic. METHODS Temsirolimus (20 mg Kg(-1) daily) was administered to freshly generated pancreatic cancer xenografts. Tumour growth inhibition was(More)
SP-303, a large proanthocyanidin oligomer isolated from the latex of the plant species Croton lechleri (Eupborbiaceae) has demonstrated broad activity against a variety of DNA and RNA viruses. In cell culture, SP-303 exhibits potent activity against isolates and laboratory strains of respiratory syncytial virus (RSV), influenza A virus (FLU-A) and(More)
In order to examine whether a polymorphism in the promoter region of the myeloperoxidase (MPO) gene is associated with lung cancer among male smokers, we conducted a case-control study nested within a Finnish clinical trial cohort. Although we found no evidence of an overall association between lung cancer risk and MPO genotype, the variant MPO genotype was(More)
