BACKGROUND Controversy persists about optimal mammography screening strategies. OBJECTIVE To evaluate screening outcomes, taking into account advances in mammography and treatment of breast cancer. DESIGN Collaboration of 6 simulation models using national data on incidence, digital mammography performance, treatment effects, and other-cause mortality. SETTING United States. PATIENTS Av...
Research to determine patterns of genetic differentiation among and within field populations of Crom.um quercuum f. sp.firsifome using RAPD markers is currently underway in the molecular genetics laboratory at the Southern Institute of Forest Genetics. Fungal tissue was collected as a drop of spermatia or scrapings of a discrete hymenium fiom a single gall on each tree sampled at a location. Co...
Contents Preface Foreword Recent highlights On the role of cirrus clouds in climate 11 Pathways in the ocean 19 Monitoring of tropical processes relevant to climate change 29 Current projects Preface • In 2001 the Intergovernmental Panel on Climate Change (ipcc) published its Third Assessment Report (tar). It was concluded that " There is new and stronger evidence that most of the warming obser...
The El Niño-Southern Oscillation (ENSO) and the variability in the Pacific subtropical highs (PSHs) have major impacts on social and ecological systems. Here we present an Atlantic capacitor effect mechanism to suggest that the Atlantic is a key pacemaker of the biennial variability in the Pacific including that in ENSO and the PSHs during recent decades. The 'charging' (that is, ENSO imprintin...
BACKGROUND Radix notoginseng is used in Chinese medicine to improve blood circulation and clotting; however, the pharmacological activities of other parts of Panax notoginseng have yet to be explored. The present study reports the anti-oxidative effects of various parts of Panax notoginseng. METHODS Various parts of Panax notoginseng, including the biennial flower, stem-leaf, root-rhizome, fi...
Objective: The biennial epidemic pattern of respiratory syncytial virus (RSV) circulation in Croatia has been preserved and could not be related to climatic factors and the predominant RSV subtypes. The possibility that the circulation of different RSV genotypes affect the outbreak cycle in children in Croatia (Zagreb region) over a period of 3 consecutive years was explored in the paper. Metho...
Monocarpic plant species, where reproduction is fatal, frequently exhibit variation in the length of their prereproductive period prior to flowering. If this life-history variation in flowering strategy has a genetic basis, genotype-by-environment interactions (G x E) may maintain phenotypic diversity in flowering strategy. The native monocarpic plant Common Evening Primrose (Oenothera biennis ...
