Shiga toxin 2 (Stx2), one of the most important virulence factors of enterohaemorrhagic Escherichia coli (EHEC), is encoded by phages. These phages (Stx2 phages) are often called lambda-like. However, most Stx2 phages are short-tailed, thus belonging to the family Podoviridae, and the functions of m...

The influence of metal cations on corrosion behavior of aluminum alloy (AA2024-T3) in model freshwater was examined by immersion experiments, surface analysis, and electrochemical measurements. After long-time immersion, the corrosion rate of AA2024-T3 decreased as the corrosion indicator Y increase...

GM1 gangliosidosis is a progressive, recessive, autosomal, neurodegenerative, lysosomal storage disorder that affects the brain and multiple systemic organs due to an acid β-galactosidase deficiency encoded by the GLB1 gene. This disease occurs in the Shiba Inu breed, which is one of the most popula...

With the aging of society, the incidence of chronic kidney disease (CKD), a common cause of death, has been increasing. Transcription factor EB (TFEB), the master transcriptional regulator of the autophagy/lysosomal pathway, is regarded as a promising candidate for preventing various age-related dis...

Safe water supply and sanitation are basic human needs and the basis of sustainable social development. In Bangladesh, an urgent issue related to water supply is wide spread arsenic contamination of groundwater, on which most people in this country rely for drinking water through tube-wells. Althoug...

The disaster could be classified into 2 major types, ‘natural disaster' and ‘environmental disaster'. The environmental disaster is thought to be classified into ‘disaster from environment destruction', ‘disaster from environment pollution', and ‘disaster from environment inflexibility'. Most of eno...

Abstract In order to understand the basic properties of KH2PO4 (KDP) ferroelectric thin films from the microscopic view point, Raman scattering measurements were carried out above and below the phase transition temperature. The KDP thin films were grown on the Ag-films by the slow evaporation method...

The results of the corrosion nature of aluminum 7075 alloy in a cation-containing aqueous medium are reported by using gravimetric tests and surface analysis. The investigation showed a substantial increase in the mass of the specimens after the immersion experiments, while a minor mass change was s...

Abstract Seasonal and gender impacts have not been well considered in fecal exposure assessment, especially in low- and middle-income countries. This study examined the seasonal and gender impacts on fecal exposure trends in children through daily living activities in an urban slum in Bangladesh. We...
