  • This suggested a variation in tandem repeat copy numbers in the VNTR loci. (pasteur.fr)
  • These observations suggest that Piezo1 is a biologically critical protein with high importance in humans and related species. (ukri.org)
  • Many cases of canine MAC infection discussed in the literature have not been typed at subspecies level ( 4 , 8 ). (frontiersin.org)
  • Since type 2 HCV infections in the Turkish population are rare, the possibility of nosocomial infection was investigated by means of phylogenetic analysis of viral sequences amplified by the polymerase chain reaction in the NS5b region. (ox.ac.uk)
  • This finding suggests that if B. pseudomallei has been introduced to the region from northern Australia, it was not in recent times, and there has not been a point source of infection. (edu.au)
  • The gene Tri12 encodes a predicted Major Facilitator Superfamily protein suggested to play a role in export of trichothecene mycotoxins produced by Fusarium species. (usda.gov)
  • According to a study published September 29 in Nature, the defining feature of each type of tauopathy may boil down to a minute detail that requires a cryoelectron microscope to see. (alzforum.org)
  • The study, led by Dr. Carla Lacerda from the Department of Chemical Engineering at Texas Tech University in Lubbock, reports that 10 percent cyclic radial strain on isolated mitral valve anterior leaflets provides a true physiological environment that can be used for mechanistic studies and drug discovery. (drugdiscoverynews.com)
  • In the current study, Lacerda and colleagues used proteomic analysis to evaluate the effect of 10 percent cyclic radial strain on isolated heart valves. (drugdiscoverynews.com)
  • SIGNIFICANCE AND IMPACT OF THE STUDY: A common pattern of stress response between efficient wine strains exists, which could be used as a criterion for selection. (unboundmedicine.com)
  • In this study, we investigated the mutational profile and EBV strains of 71 ENKTL cases from Latin America (42 from Mexico, 17 from Peru, and 12 from Argentina) and compared it with Asian cohorts. (tmu.edu.tw)
