Escherichia coli strains of serogroup 0115:K(-):F165 have been associated with septicemia in calves and piglets. These strains express a capsular antigen referred to as K"V165" which inhibits agglutination of the 0 antigen by anti-0115 serum. We used hybrid transposon TnphoA mutants M48, 18b, and 2, and a spontaneous 0-agglutinable mutant, 5131a, to evaluate the role of K"IV165" in the pathogen...

Sub-Neptunes (Rp~1.25-4 REarth) remain the most commonly detected exoplanets to date. However, it remains difficult for observations tell whether these intermediate-sized have surfaces and where their are located. Here we propose that abundances of trace species in visible atmospheres sub-Neptunes can be used as proxies determining existence approximate surface conditions. As an example, a stat...

Observations of present-day mass-loss rates for close-in transiting exoplanets provide a crucial check on models planetary evolution. One common approach is to model the absorption signal during transit in lines like He I 10830 with an isothermal Parker wind, but this leads degeneracy between assumed outflow temperature $T_0$ and rate $\dot{M}$ that can span orders magnitude $\dot{M}$. In study...

BACKGROUND Nasopharyngeal carcinoma (NPC) is a common malignancy in South-East Asia. NPC is characterized by distant metastasis and poor prognosis. The pathophysiological mechanism of nasopharyngeal carcinoma is unknown. This study aimed to identify the crucial miRNAs in nasopharyngeal carcinoma and their target genes, and to discover the potential mechanism of nasopharyngeal carcinoma developm...
