In mammals, the biological activity of the stem/progenitor compartment sustains production of mature gametes through spermatogenesis.Spermatogonial stem cells and their progeny belong to the class of undifferentiated spermatogonia, a germ cell population found on 1964-1973 Engine - Valve Cover the basal membrane of the seminiferous tubules.A large
A large part of Retail and Online foodborne outbreaks related to Listeria monocytogenes are linked to meat and meat products.Especially, recontamination of meat products and deli-meat during slicing, packaging, and repackaging is in the focus of food authorities.In that regard, L.monocytogenes persistence in multi-species biofilms is one major issu
There are great differences in the distribution characteristics of shock waves produced by ammunition explosions at different altitudes.At present, there are many studies on plain explosion shock waves, but there are few studies on the distribution characteristics of plateau explosion shock waves, and there is still a lack of complete analysis and
ABSTRACT Surface waters function as ecological niches where Salmonella enterica can persist and disseminate to fresh produce production systems.We examined the genomic characteristics of S.enterica serotypes Agona (n = 86), Braenderup (n = 47), Muenchen (n = Watches 53), and Panama (n = 69) isolates from surface waters in Chile, Mexico, and Brazil
Abstract Background Top-down homogeneous multiplexed tandem mass (HomMTM) spectra are generated from modified proteoforms of the same protein with different post-translational modification patterns.They are frequently observed in the analysis of ultramodified proteins, some proteoforms of which have similar molecular weights and cannot be well sepa
