  • 'Masking the evidence': perspectives of the COVID-19 pandemic. [Editorial]
    J Clin Nurs. 2020 Jul 03 [Online ahead of print]Smith GD, Ng F, Watson R
  • The COVID-19 pandemic presents a severe and acute public health emergency around the world. The event of the pandemic has seen an upsurge in the general public wearing of disposable surgical masks (DSM) and other types of face masks. The World Health Organisation of mask wearing has been widely debated in the press a(WHO) have changed their advice, to now recommend the routine wearing of fabric m…
  • Realization of a Push-Me-Pull-You swimmer at low Reynolds numbers. [Journal Article]
    Bioinspir Biomim. 2020 Jul 03 [Online ahead of print]Silverberg O, Demir E, … Araci IE
  • Locomotion at low Reynolds numbers encounters stringent physical constraints due to the dominance of viscous over inertial forces. A variety of swimming microorganisms has demonstrated diverse strategies to generate self-propulsion in the absence of inertia. In particular, ameboid and euglenoid movements exploit shape deformations of the cell body for locomotion. Inspired by these biological orga…
  • Calcium phosphate nanoparticles as intrinsic inorganic antimicrobials: mechanism of action. [Journal Article]
    Biomed Mater. 2020 Jul 03 [Online ahead of print]Wu VM, Huynh E, … Uskokovic V
  • This is the final report of the study aimed at assessing the antimicrobial activity of CP nanoparticles delivered in the form of hydroxyapatite (HAp) or amorphous CP (ACP) and understanding the fundamental principles behind their mechanisms of action. Not responding to propidium iodide and causing no gross morphological changes except moderate stress-induced filamentation in E. coli, CP nanoparti…
  • Detection of lard in butter using Raman spectroscopy combined with chemometrics. [Journal Article]
    Food Chem. 2020 Jun 15; 332:127344.Taylan O, Cebi N, … Bakhsh AA
  • There is a contentious need for robust and rapid methodologies for maintaining the authenticity of foods and food additives. The current paper presented a new Raman spectroscopy-based methodology for detection and quantification of lard in butter. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were successfully performed for the classification and discrimination of but…
  • Measurement of selected trace elements in Olea europaea L. cv. 'Sigoise'. [Journal Article]
    J Trace Elem Med Biol. 2020 Jun 18; 62:126595.Nedjimi B
  • CONCLUSIONS: The present work indicates that the concentrations of macro- and microelements (Cu, Fe, K, Mn and Zn) were above the threshold limits for possible plant deficiencies except for P, and this cultivar can easily accumulate high amount of K in their organs (predominance in olives). These findings will be used to achieve efficient fertilization for O. europaea orchards.
  • A divergent mode of activation of a nitrosyl iron complex with unusual antiangiogenic activity. [Journal Article]
    J Inorg Biochem. 2020 Jun 20; 210:111133.Carvalho EM, Ridnour LA, … Lopes LGF
  • Nitric oxide (NO) and nitroxyl (HNO) have gained broad attention due to their roles in several physiological and pathophysiological processes. Remarkably, these sibling species can exhibit opposing effects including the promotion of angiogenic activity by NO compared to HNO, which blocks neovascularization. While many NO donors have been developed over the years, interest in HNO has led to the re…
  • Biosynthesis and tissue-specific partitioning of camphor and eugenol in Ocimum kilimandscharicum. [Journal Article]
    Phytochemistry. 2020 Jun 30; 177:112451.Singh P, Kalunke RM, … Giri AP
  • In Ocimum kilimandscharicum, the relative volatile composition of camphor in leaves was as high as 55%, while that of eugenol in roots was 57%. These metabolites were differentially partitioned between the aerial and root tissues. Global metabolomics revealed tissue-specific biochemical specialization, evident by the differential distribution of 2588 putative metabolites across nine tissues. Next…
  • Analysis of codon usage bias in potato virus Y non-recombinant strains. [Journal Article]
    Virus Res. 2020 Jun 30 [Online ahead of print]Gómez MM, de Mello Volotão E, … Cristina J
  • Potato virus Y (PVY) is a member of the genus Potyvirus, family Potyviridae, is considered one of the most devastating pest affecting economically important crops, such as potato, tobacco, tomato and pepper, representing a serious threat due to high incidence and worldwide distribution. Its economic significance as well as it biological and molecular complexities have aroused great attention, thu…
  • Low concentrations of 3-O-methylglucose improve post thaw recovery in cryopreserved bovine spermatozoa. [Journal Article]
    Cryobiology. 2020 Jun 30 [Online ahead of print]Bhat MH, Blondin P, … Benson JD
  • A number of studies have explored the use of membrane permeable (usually metabolizable) and membrane impermeable saccharides to protect cells in general, and sperm in particular during cryopreservation. Critical concentrations for protective levels of sugars frequently range between 50 mmol/L and 500 mmol/L, where efficacy is attributed to the sugar's membrane stabilizing and glass forming attrib…
  • Porous carbon supported Calcium oxide for CO2 adsorption and separation of CO2/CH4. [Journal Article]
    Environ Technol. 2020 Jul 03 [Online ahead of print]Jonnalagadda M, Ibrahim SM, … Mutyala S
  • Calcium oxide incorporated porous carbon materials were synthesized by the impregnation method to study CO2 adsorption and separation of CO2/CH4. The X-ray diffraction, Raman analysis, N2 isotherms at 77 K, and SEM with EDX analysis were used to characterize synthesized materials. XRD and N2 isotherm results have confirmed that synthesized carbon has porosity, and EDX analysis has reported that t…
  • Genetic structure and insecticide resistance characteristics of fall armyworm populations invading China. [Journal Article]
    Mol Ecol Resour. 2020 Jul 03 [Online ahead of print]Zhang L, Liu B, … Xiao Y
  • The rapid wide-scale spread of fall armyworm (Spodoptera frugiperda) has caused serious crop losses globally. However, differences in the genetic background of subpopulations and the mechanisms of rapid adaptation behind the invasion are still not well understood. Here we report the assembly of a 390.38Mb chromosome-level genome of fall armyworm derived from south-central Africa using Pacific Bio…
  • Phylogenetic signals and predictability in plant-soil feedbacks. [Journal Article]
    New Phytol. 2020 Jul 03 [Online ahead of print]Wandrag EM, Bates SE, … Duncan RP
  • There is strong evidence for a phylogenetic signal in the degree to which species share co-evolved biotic partners and in the outcomes of biotic interactions. This implies there should be a phylogenetic signal in the outcome of feedbacks between plants and soil microbiota they cultivate. However, attempts to identify a phylogenetic signal in plant-soil feedbacks have produced mixed results. We cl…
