Prev Vet Med 2021 Jul 13;194:105431. Epub 2021 Jul 13.

Department of Large Animal Clinical Sciences, University of Florida, Gainesville, 32610, USA; Department of Animal Sciences, Institute of Food and Agricultural Sciences, University of Florida, Gainesville, 32610, USA. Electronic address:

Precision dairy farming, specifically the design of management strategies according to the animal's needs, may soon become the norm since automated technologies that generate large amounts of data for each individual are becoming more affordable. Our objectives were to determine whether the use of behavioral changes could improve the accuracy of prediction of the risk of metritis and the risk of clinical cure of cows diagnosed with metritis. Addition of behavioral data to the algorithms to predict the outcomes of interest increased their accuracy by 7 to 32%. Read More

Hurricane/tropical storm rainwater chemistry in the US (from 2008 to 2019).

Sci Total Environ 2021 Jul 17;798:149009. Epub 2021 Jul 17.

Physical and Environmental Sciences Department, Texas A & M University - Corpus Christi, 6300 Ocean Drive, Corpus Christi, TX 78412, United States of America; Center for Water Supply Studies, Texas A & M University - Corpus Christi, 6300 Ocean Drive, Corpus Christi, TX 78412, United States of America.

Rainwater chemistry of extreme rain events is not well characterized. This is despite an increasing trend in intensity and frequency of extreme events and the potential excess loading of elements to ecosystems that can rival annual loading. Thus, an assessment of the loading imposed by hurricane/tropical storm (H/TS) can be valuable for future resiliency strategies. Read More

Effect of Biomodulina-T® and VA-MENGOC-BC® on lymphocyte subpopulations in older adults.

Exp Gerontol 2021 Jul 26:111497. Epub 2021 Jul 26.

Institute of Hematology and Immunology, Immunochemistry-Immunology Department, 19th St, between 8th and 10th St, Vedado, 10400 Plaza de la Revolución, Havana, Cuba.

Introduction: The elderly population suffers from the natural process called immunosenescence, which may be related to the high mortality rates it has against the SARS-CoV2 virus, which is why therapies that improve the immune status are required. The combined treatment of the VA-MENGOC-BC® (V-BC) vaccine and the Biomodulina T® (BT) drug could achieve this purpose. This treatment could immunomodulate both the innate and adaptive branches of the immune system simultaneously. Read More

Improvement of sensitivity and specificity for laminar BOLD fMRI with double spin-echo EPI in humans at 7 T.

Neuroimage 2021 Jul 26:118435. Epub 2021 Jul 26.

Center for Neuroscience Imaging Research, Institute for Basic Science (IBS), Suwon, South Korea; Department of Biomedical Engineering, Sungkyunkwan University, Suwon, South Korea; Department of Intelligent Precision Healthcare Convergence, Sungkyunkwan University, Suwon, South Korea. Electronic address:

Mapping mesoscopic cortical functional units such as columns or laminae is increasingly pursued by ultra-high field (UHF) functional magnetic resonance imaging (fMRI). The most popular approach for high-resolution fMRI is currently gradient-echo (GE) blood oxygenation level-dependent (BOLD) fMRI. However, its spatial accuracy is reduced due to its sensitivity to draining vessels, including pial veins, whereas spin-echo (SE) BOLD signal is expected to have higher spatial accuracy, albeit with lower sensitivity than the GE-BOLD signal.

Evolution of physiological performance in invasive plants under climate change.

Evolution 2021 Jul 29. Epub 2021 Jul 29.

Instituto de Ciencias Biológicas, Universidad de Talca, Talca, Chile.

Climate change is expected to promote biological invasions. Invasive species often undergo adaptive evolution, but whether invasive species show greater evolutionary potential than their native counterparts under climate change has rarely been evaluated. We conducted experimental evolution trials comparing the evolution of physiological performance (light-saturated photosynthetic rate, A ) of coexisting and closely related 1) invasive-native species pairs from Arid, Alpine and Antarctic ecosystems, and 2) an invasive-naturalized species pair from a Mediterranean ecosystem differing in invasiveness.

Synthesis and electrochemical properties of ZnTiO/g-CN composites as anode materials for Li-ion batteries.

Dalton Trans 2021 Jul 29. Epub 2021 Jul 29.

School of Energy and Environment, Anhui University of Technology, Maanshan, Anhui 243002, PR China.

Zn2Ti3O8/g-C3N4 (0, 1, 3 and 8 wt%) composites were prepared via a simple solvothermal method, and their physical and electrochemical properties were systematically analyzed. SEM and HRTEM results show that the Zn2Ti3O8/g-C3N4 spherical structures with width sizes of about 500-700 nm are plump and uniform. Moreover, g-C3N4 with a large specific surface area can effectively buffer the deformation of Zn2Ti3O8 and reduce the resistance of Zn2Ti3O8 charge transfer and Li+ diffusion, thus improving the conductivity of Zn2Ti3O8.

Grafted Nanoparticle Surface Wetting during Phase Separation in Polymer Nanocomposite Films.

ACS Appl Mater Interfaces 2021 Jul 29. Epub 2021 Jul 29.

Department of Materials Science and Engineering, University of Pennsylvania, Philadelphia, Pennsylvania 19104, United States.

Wetting of polymer-grafted nanoparticles (NPs) in a polymer nanocomposite (PNC) film is driven by a difference in surface energy between components as well as bulk thermodynamics, namely, the value of the interaction parameter, χ. The interplay between these contributions is investigated in a PNC containing 25 wt % polymethyl methacrylate (PMMA)-grafted silica NPs (PMMA-NPs) in poly(styrene--acrylonitrile) (SAN) upon annealing above the lower critical solution temperature (LCST, 160 °C). Atomic force microscopy (AFM) studies show that the areal density of particles increases rapidly and then approaches 80% of that expected for random close-packed hard spheres. Read More

The Effect of Zoom Magnification and Large Display on Video Comprehension in Individuals With Central Vision Loss.

Transl Vis Sci Technol 2021 Jul;10(8):30

Schepens Eye Research Institute, Massachusetts Eye and Ear, Boston, MA, USA.

Purpose: A larger display at the same viewing distance provides relative-size magnification for individuals with central vision loss (CVL). However, the resulting large visible area of the display is expected to result in more head rotation, which may cause discomfort. We created a zoom magnification technique that placed the center of interest (COI) in the center of the display to reduce the need for head rotation. Read More
