Psychological flexibility prospectively predicts COVID-19 PPE use across a two-month interval.

Perceived susceptibility, psychological flexibility and health behaviors (PPE use, social distancing) were measured at two time points spaced 2 months apart during the height of the COVID-19 pandemic and lockdown in the U.S.A (Time 1 April 2020; Time 2 June 2020).

Impact of stress and decision fatigue on parenting practices related to food and physical activity during COVID-19.

Background: The COVID-19 pandemic has resulted in substantial disruptions to daily functioning and lifestyle behaviours, with negative health consequences for youth. Parents play a large role in their children's health behaviour; yet changes to parenting behaviours during the pandemic related to food and physical activity remain relatively unexplored. The present study is the first to our knowledge to examine specific changes in American parents' parenting behaviours related to food and physical activity during COVID-19, and potential correlates of such changes, including perceived stress and decision fatigue.

Consequences of Picky Eating in College Students.

Objective: To examine the relation between young adult picky eating (PE) and psychosocial outcomes (eg, social phobia, quality of life) and dietary intake.

Design: Cross-sectional study including demographic, quantitative, and qualitative measures.

Participants: Midwestern undergraduate convenience sample (n = 488) recruited early 2020.

Predicting personal protective equipment use, trauma symptoms, and physical symptoms in the USA during the early weeks of the COVID-19 lockdown (April 9-18, 2020).

The COVID-19 pandemic created a complex psychological environment for Americans. In this study, 450 MTurk workers completed measures of sociodemographic characteristics, perceived risk for COVID-19, general perceived vulnerability to disease, intolerance of uncertainty, and psychological flexibility. These variables were used to predict COVID-19 preventive health behaviors (PPE use), psychological distress, and physical symptoms.

Psychological reactions to COVID-19: Survey data assessing perceived susceptibility, distress, mindfulness, and preventive health behaviors.

The COVID-19 pandemic created a complex psychological environment for persons in America. A total of 450 USA MTurk workers completed measures of: (a) basic demographic characteristics; (b) health risk factors for COVID-19; (c) perceived susceptibility variables related to COVID-19; (d) COVID-19 preventive health behaviors; and (e) distress, physical symptoms, and quality of life measures. The surveys were completed between April 9, 2020 and April 18, 2020.

Genome Sequence Analysis of New Isolates of the Winona Strain of Plum pox virus and the First Definitive Evidence of Intrastrain Recombination Events.

Plum pox virus (PPV) is genetically diverse with nine different strains identified. Mutations, indel events, and interstrain recombination events are known to contribute to the genetic diversity of PPV. This is the first report of intrastrain recombination events that contribute to PPV's genetic diversity.

Analysis of the complete genome of a virus associated with twisted leaf disease of cherry reveals evidence of a close relationship to unassigned viruses in the family Betaflexiviridae.

The genome of a virus associated with cherry twisted leaf disease (CTLaV, isolate ZH) was sequenced and consists of 8431 nucleotides, excluding a poly(A) tail at the 3' end. Genome analysis shows that CTLaV-ZH represents a new and distinct species and has a genome organization similar to those of unassigned viruses in the family Betaflexiviridae. The CTLaV-ZH genome has five open reading frames (ORFs), with putative ORFs within ORF2 and ORF5, identified as ORF2a and ORF5a, respectively.

Two novel mitoviruses from a Canadian isolate of the Dutch elm pathogen Ophiostoma novo-ulmi (93-1224).

Background: Ophiostoma novo-ulmi is the causative agent of Dutch elm disease (DED). It is an ascomycetous filamentous fungus that ranks as the third most devastating fungal pathogen in Canada. The disease front has spread eastward and westward from the epicentre in Ontario and Quebec and is threatening elm populations across the country.

Molecular Analysis of a Plum pox virus W Isolate in Plum Germplasm Hand Carried into the USA from the Ukraine Shows a Close Relationship to a Latvian Isolate.

Four of 19 Prunus germplasm accessions hand carried from the Ukraine into the United States without authorization were found to be infected with Plum pox virus (PPV). Of the three isolates characterized, isolates UKR 44189 and UKR 44191 were confirmed to be isolates of PPV strain W, and UKR 44188 was confirmed to be an isolate of PPV strain D. UKR 44189 and UKR 44191 are very closely related to the PPV strain W isolate LV-145bt (HQ670748) from Latvia.

Chloroplastic glutamine synthetase is activated by direct binding of aluminium.

Acidification of soils may release water soluble, toxic aluminium species from clay minerals. Al interferes with a wide range of physical and cellular processes. Glutamine synthetase (GS, EC 6.

Use of Luminex xMAP-derived Bio-Plex bead-based suspension array for specific detection of PPV W and characterization of epitopes on the coat protein of the virus.

A panel of monoclonal antibodies (MAbs) directed against the N-terminus region of the coat protein (CP) of strain PPV W (isolate 3174) was generated by immunizing mice with recombinant peptides. The best performing MAbs were identified as 2C3 and 10G7. MAb 2C3 was selected for comparison of a standard TAS-ELISA protocol with a Luminex xMAP technology-derived bead-based suspension array system described as a triple antibody sandwich-microsphere immunoassay (TAS-MIA).

Use of reverse transcription loop-mediated isothermal amplification for the detection of Plum pox virus.

A one step, accelerated reverse transcription loop-mediated isothermal amplification (RT-LAMP) procedure was developed for the detection of Plum pox virus (PPV). The six primers required for accelerated RT-LAMP were designed using a conserved region in the C-terminus of the coat protein coding region of PPV. RT-LAMP was used to detect isolates of five strains of PPV including the strains D, M, EA, C, and W.

Real-time RT-PCR and SYBR Green I melting curve analysis for the identification of Plum pox virus strains C, EA, and W: effect of amplicon size, melt rate, and dye translocation.

Real-time RT-PCR and SYBR green I melt curve analysis of a 74 bp amplicon enabled identification of Plum pox virus strains C, EA, and W, with distinct T(m)'s associated with each strain. This test is a useful supplement to a real-time RT-PCR test described earlier that was used to distinguish PPV strains D and M. A longer fragment of 155 bp was not effective for strain identification.

Detection and differentiation of Plum pox virus using real-time multiplex PCR with SYBR Green and melting curve analysis: a rapid method for strain typing.

A real-time multiplex PCR procedure with melting curve analysis, using the green fluorescence dye SYBR Green I, was developed for rapid and reliable identification of Plum pox virus (PPV) isolates of strains D and M. Members of the different strains were identified by their distinctive melting temperatures (T(m)s); 84.3-84.
