Objective: To evaluate the molluscicidal effect of the chlorosalicylicamide sustained-release granules (LDS-SRG) on Oncomelania hupensis.
Methods: Seven effective concentrations or dosages of LDS-SRG, 0.1, 0.
We report here a series of novel spontaneously healable thermoplastic elastomers (TPEs) with a combination of improved mechanical and good autonomic self-healing performances. Hard-soft diblock and hard-soft-hard triblock copolymers with poly[exo-1,4,4a,9,9a,10-hexahydro-9,10(1',2')-benzeno-l,4-methanoanthracene] (PHBM) as the hard block and secondary amide group containing norbornene derivative polymer as the soft block were synthesized via living ring-opening metathesis copolymerization by use of Grubbs third-generation catalyst through sequential monomer addition. The microstructure, mechanical, self-healing, and surface morphologies of the block copolymers were thoroughly studied.

- The study investigates the rapid evolution of the influenza A virus in Shanghai, focusing on A/H1N1 and A/H3N2 strains from 2005 to 2008.
- Key findings indicate significant antigenic differences between older and more recent A/H1N1 strains, linked to a specific amino acid mutation.
- Results also reveal substantial antigenic drift in A/H3N2 strains, highlighting the need for updating the vaccine component for better effectiveness against recently circulating viruses.
[Study on evolutionary origin of influenza A virus (H1N1) based on HA gene].

Article Synopsis
- The study aimed to analyze the evolutionary rate and divergence time of the influenza A virus HA gene, focusing on recent pandemic strains and their transmission origins.
- Researchers collected a total of 344 H1 sequences from various sources, using molecular clock theory to calculate substitution rates and the time to the most recent common ancestor (tMRCA).
- Results showed significant clustering of H1 sequences from the US with Asian swine, indicating a possible origin from prolonged circulation in human and swine populations in America, with no evidence linking strains from China to the current outbreak.
Objective: To analyze the type and subtype distribution of influenza virus and the genetic evolution of hemagglutinin (HA) in Shanghai area during 2004 to 2008.
Methods: All 962 throat swabs were collected from influenza-like patients in 5 influenza sentry hospitals and influenza outbreaks. Influenza viruses were isolated in MDCK cell lines, and then viral types and subtypes were identified.
