Synthesis and preclinical evaluation of a selective MET kinase positron emission tomography tracer.

The tyrosine kinase MET (hepatocyte growth factor receptor) is activated or mutated in a wide range of cancers and is often correlated with a poor prognosis. Precision medicine with positron emission tomography (PET) can potentially aid in the assessment of tumor biochemistry and heterogeneity, which can prompt the selection of the most effective therapeutic regimes. The selective MET inhibitor PF04217903 (1) formed the basis for a bioisosteric replacement, leading to the deoxyfluorinated analog [ F]2.

Four new subspecies of butterflies (Lepidoptera, Papilionoidea) from Phu Quoc Island, southern Vietnam.

We describe and illustrate four new subspecies of Papilionoidea butterflies which were collected from Phu Quoc Island, Kien Giang province, southern Vietnam between 2006 and 2017. These are papilionid Graphium antiphates matsui T. Saito & Vu subspec.

Thirty years of nutrients and biogeochemistry in the Norwegian, Greenland and Iceland Seas, 1990-2019.

This dataset contains biogeochemical samples analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR), from the Norwegian, Greenland and Iceland Seas. Number of surveys and stations have varied greatly over the last 3 decades. IMR is conducting one annual Ecosystem Survey in April-May each year, with multiple trawl surveys and net tows, but only CTD water collections are reported here.

Thirty Years of Nutrient Biogeochemistry in the Barents Sea and the adjoining Arctic Ocean, 1990-2019.

This dataset contains biogeochemical samples from the Barents Sea and Arctic region analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR). Number of surveys and stations visited in the Barents Sea and Arctic has varied over the last 30 years. One major effort is the annual Ecosystem Survey in the fall, with multiple trawl surveys, net tows and CTD water sampling.

A new species related to Ypthima praenubila Leech, 1891 in Vietnam and China (Lepidoptera, Nymphalidae, Satyrinae).

We describe a new species of satyrine butterfly, Ypthima thao Monastyrskii Lang sp. nov., recently discovered in northern Vietnam and southwestern China.
