In this study the peculiar Andean grass genus Aphanelytrum, with two species, is reduced to Poa subsect. Aphanelytrum comb. & stat. nov. A third species, Festuca reclinata, is assigned to the subsection, which shows states transitional between a more typical Poa and Aphanelytrum. Poa subgen. Poa supersect. Homalopoa sect. Dioicopoa subsect. Aphanelytrum comb. & stat. nov. is characterized in ha...

The complete genome sequence of 6.45 Mb is reported here for Pseudomonas trivialis strain IHBB745 (MTCC 5336), which is an efficient, stress-tolerant, and broad-spectrum plant growth-promoting rhizobacterium. The gene-coding clusters predicted the genes for phosphate solubilization, siderophore production, 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity, indole-3-acetic acid (IAA) pr...

The natural resistance of Escherichia coli to pyrazinoic acid (POA), the active derivative of pyrazinamide, was investigated. The TolC mutant was found to be more susceptible to POA and other weak acids than the wild-type strain. Mutation in EmrB but not AcrB efflux protein slightly increased POA susceptibility. Two transposon mutants with increased susceptibility to POA were found to harbor mu...

BACKGROUND Prescription opioid analgesic (POA) utilization has steeply increased globally, yet is far higher in established market economies than elsewhere. Canada features the world's second-highest POA consumption rates. Following increases in POA-related harm, several POA control interventions have been implemented since 2010. METHODS We examined trends and patterns in POA dispensing in Ca...

OBJECTIVE To evaluate how the accuracy of present-on-admission (POA) reporting affects hospital 30-day acute myocardial infarction (AMI) mortality assessments. DATA SOURCES A total of 2005 California patient discharge data (PDD) and vital statistics death files. STUDY DESIGN We compared hospital performance rankings using an established model assessing hospital performance for AMI with (1) ...

In this column, we continue our presentation of the new OMG Portable Object Adapter (POA) [1]. The POA was adopted by the OMG in mid-1997 as a replacement for the Basic Object Adapter (BOA), which was the original CORBA object adapter. As we described in our last column, the BOA was a major source of portability problems for CORBA applications due to its imprecise specification. Serious users o...

I have read with great interest the paper recently published in your journal by Uchino et al. [5] describing the persistent primitive olfactory artery (POA). In the anatomical paper on cerebral arteries, two important points are required. One is description of the detailed arterial anatomy (static anatomy). In this sense, new information of the incidence of the POA being 0.14% and no laterality...

The marine‑derived oxalicumone A (POA) has been demonstrated as a potent anti‑tumor bioactive agent for a variety of human carcinoma, but to the best of our knowledge, remains to be evaluated in healthy liver cells. As many drugs distribute preferentially in the liver, the present study aimed to investigate the effects of POA on apoptosis, oxidative stress and mitochondrial function in L‑02 hea...
