OBJECTIVE To analyze the status and trend of injury deaths in Chinese people, and provide basic evidence for injury interventions. METHODS Data came from 2004-2005 the 3rd national retrospective sampling survey of death cause and covered 31 province-level regions and 160 surveillance spots in the interior of China, Total 142 660 482 person years were investigated. To describe the status of in...

The gamma-aminobutyrate/benzodiazepine-receptor complex has been purified from a Triton X-100 extract of crude synaptic membranes from pig cerebral cortex and cerebellum by a combination of affinity and ion-exchange chromatography. [3H]Flunitrazepam binding activity was purified 2200-fold from cortex with an overall yield of 2%. The dissociation constants for the binding of [3H]muscimol and [3H...

We employed Bayesian coalescent modeling of samples of mitochondrial control region sequences in two species of shorebird, Red Knots (Calidris canutus) and Dunlins (Calidris alpina) to estimate evolutionary effective population size, population divergence times, and time to most recent common ancestor of genes in the samples. The gene trees for the two species contrast sharply: knot haplotypes ...

The genus Flavivirus includes some of the most important human viral pathogens, and its members are found in all parts of the populated world. The temporal origin of diversification of the genus has long been debated due to the inherent problems with dating deep RNA virus evolution. A generally accepted hypothesis suggests that Flavivirus emerged within the last 10 000 years. However, it has be...

Fludarabine can exacerbate idiopathic thrombocytopenia (ITP) in chronic lymphocytic leukemia (CLL). We report 3 CLL patients with refractory fludarabine-associated ITP who responded to rituximab. The patients had Rai stages III, III, and IV disease. Before fludarabine treatment, the platelet counts were 141 000/microL, 118 000/microL, and 70 000/microL. ITP developed within week 1 of cycle 3 in...

The yearly incidence of the acute myeloblastic leukaemias (AMLs) in European adults is 5–8 cases per 100 000 individuals, and in myelodysplastic syndromes (MDSs) 4–5 new cases/100 000 are expected yearly. In individuals >60 years incidences of both AMLs and MDSs increase significantly, reaching 40–60 new cases of MDS per 100 000/year. Yearly mortality figures are 4–6 cases per 100 000 in AMLs a...

Plant macrofossils extracted from fossil woodrat (Neotoma spp.) middens at a single locale in the northwestern Great Basin were used to examine vegetation dynamics during the last 30 000 yr. Although the modem assemblage of xeric species at the study site is a recent occurrence, a large proportion of the modem plant taxa near the study locale were also found 12 000 30 000 yr BP. The persistence...

The boundaries, reach and regional importance of Armenia have ebbed and flowed over the centuries, but the current borders were drawn by Soviet cartographers and have never been fully accepted. The most significant example of the difficulties caused by the given borders is the conflict with neighbouring Azerbaijan over the territory of Nagorny Karabakh. As a consequence of the Nagorny Karabakh ...
