Electrostriction is the upsurge of strain under an electric field in any dielectric material. Oxygen-defective metal oxides, such as acceptor-doped ceria, exhibit high electrostriction 10 mV values, which can be further enhanced via interface engineering at the nanoscale. This effect in ceria is "non-classical" as it arises from an intricate relation between defect-induced polarisation and local elastic distortion in the lattice.

The predominant role of FliC contributes to the flagella-related pathogenicity of ST34 S. Typhimurium monophasic variant.

Article Synopsis
  • Over the last two decades, the monophasic variant of Salmonella enterica serovar Typhimurium, particularly the European ST34 clone, has rapidly increased in prevalence worldwide.
  • The distinct difference in ST34 S. Typhimurium is the replacement of the fljB gene, which encodes for a second-phase flagellin, with multidrug resistance cassettes, raising questions about its pathogenicity.
  • Research shows that while the absence of fljB doesn’t significantly impact various virulence factors, the deletion of the fliC gene, which encodes for the first-phase flagellin, does lead to a major reduction in these factors, indicating that fliC is crucial for the bacterium’s mot

Article Synopsis
  • A study in Chongqing, Southwest China, explored changes in scarlet fever incidence from 2005 to 2023, noting a focus on predicting cases in 2024 and 2025 amidst the impact of the COVID-19 pandemic.
  • Research showed a total of 9,593 reported cases, with children aged 3-7, particularly 6-year-olds, being the most affected group; the incidence was notably higher in boys and peaked seasonally in spring and late fall.
  • Spatial analysis indicated scarlet fever outbreaks were concentrated in urban areas, with a significant rise in cases after COVID restrictions, showing a 106.54% increase in incidence from 2015-2019 and fluctuating decreases during the

TBVs are suggested to inhibit parasite transmission from humans to Anopheles mosquitoes. For the transmission of Plasmodium parasite, a variety of factors are included in gametes fusion phase. In this step, conserved male-specific generative cell specific 1 antigen is necessary for fusion of cytoplasmic membranes of micro- and macro-gametocytes and zygot formation.

What determines informal care need among community-dwelling older adults in China? Results from a longitudinal study.

BMC Geriatr

July 2024

State Key Laboratory of Molecular Vaccinology and Molecular Diagnostics, School of Public Health, Xiamen University, Xiamen, China.

Background: With an intensified aging population and an associated upsurge of informal care need in China, there is an ongoing discussion around what factors influence this need among older adults. Most existing studies are cross-sectional and do not focus on older people living in the community. Conversely, this study empirically explores the factors that affect informal care need of Chinese community-dwelling older individuals based on longitudinal data.
