Abstract Background Evidence for historical, demographic and selective factors affecting enzyme evolution can be obtained by examining nucleotide sequence variation in candidate genes such as Lactate dehydrogenase (Ldh).Two closely related Daphnia species can be distinguished by their electrophoretic Ldh genotype and habitat.Daphnia pulex populatio
We use broadband records from a dense seismic network deployed in and around the Qaidam Basin in northwestern China to analyze the crustal phases and investigate the depth of the Conrad and Moho discontinuities as well as the P-wave velocity.Waveform cross-correlation is used to assist in the identification of the crustal phases and in determining
Históricamente, la mujer ha sido apartada del deporte en general y de algunas disciplinas deportivas en particular.Argumentos como su fragilidad física, los efectos negativos para su salud o el efecto antiestético que pudiera causar la práctica deportiva han sido las razones alegadas para ello.Estas cuestiones han sido, en muy buena parte, ya v
Bacterial biofilms, especially those formed by pathogens, have been increasingly impacting human health.Bacterial extracellular vesicle (bEV), a kind of spherical membranous structure released by bacteria, has not only been reported to be a component of the biofilm matrix but also plays a non-negligible role in the biofilm life cycle.Nevertheless,
Abstract Background Tolerance to antibiotics and persistence are associated with antibiotic treatment failures, chronic-relapsing infections, and emerging antibiotic resistance in various bacteria, including Staphylococcus aureus.Mechanisms of persistence are largely unknown, yet have been linked to physiology under low-ATP conditions and the metab
