Livistona chinensis R. Br. var. subglobosa Becc. is a subtropical fan palm distributed mainly in the islands of the Ryukyu Archipelago, Japan. Some small populations, separated by a few 100 km from the main species range, are also established on islands around northern Kyushu and Cape Ashizuri, Shikoku. Most of those are designated as national or prefectural natural treasures. We developed 20 microsatellite markers for this species and characterized them for polymorphisms within six populations. The number of alleles per locus ranged from two to nine, with an average of 4.2; the expected heterozygosity ranged from 0.16 to 0.61, with an average of 0.46. These markers will be useful for investigating disjunct range formation within L. chinensis var. subglobosa and the origins of the remote populations, providing crucial information for conservation of the populations.
General Hospital A 37-year-old, previously healthy man, with no history of serious infection, sustained a contusion on the flexor side of his right thigh. Severe pain and swelling at the wound area were present the following day. He had fever, hypotension, anuria, stupor and right leg ischemia, and was admitted on the 3rd post injury day. Although incisions were twice made in the swollen portion of his thigh for decompression, shortly after admission, the skin around the incision became necrotic on the 4th day. At the same time, adult respiratory distress syndrome, disseminated intravascular coagulation, and profound hypotension developed rapidly, and cathecolamine infusion, mechanical ventrilation, hemodialysis and debridement of the necrotizing skin and muscle were needed. However, erythema with blisters extended to both legs, the lower abdomen and bilateral chest, and he died due to circulatory collapse on the 6th day. Group A streptococcal organisms were isolated from the necrotizing skin, muscles and blood. The serotype of this strain was M22, which produces exotoxins type B and C in vitro.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
