Uptake and translocation of nano/microplastics by rice seedlings: Evidence from a hydroponic experiment.

J Hazard Mater 2021 Jul 21;421:126700. Epub 2021 Jul 21.

College of Environment and Safety Engineering, Qingdao University of Science and Technology, Qingdao, Shandong Province 266042, PR China. Electronic address:

Microplastics (MPs) are emerging contaminants in terrestrial systems that cause diverse impacts on plants. However, little is known about whether MPs especially micro-sized MPs can be accumulated and translocated in plants particularly food crops. Hereby, a hydroponic experiment was conducted to verify whether nano-sized (80 nm) and micro-sized (1 µm) fluorescently labeled polystyrene (PS) microspheres can enter rice roots and translocate to aerial parts.

PLoS One 2020 7;15(2):e0228647. Epub 2020 Feb 7.

Department of Animal and Poultry Science, University of Saskatchewan, Saskatoon, Saskatchewan, Canada.

The objective of this research was to evaluate activation of the ileal brake in broiler chickens using diets containing semi-purified wheat (WS; rapidly and highly digested) and pea (PS; slowly and poorly digested) starch. Diets were formulated to contain six WS:PS ratios (100:0, 80:20, 60:40, 40:60, 20:80, 0:100) and each starch ratio was fed to 236 Ross 308 male broilers housed in 4 litter floor pens. At 28 d of age, the effect of PS concentration was assessed on starch digestion, digestive tract morphology, and digesta pH and short-chain fatty acid (SCFA) concentration. Read More

A QTL associated with leaf trichome traits has a major influence on the abundance of the predatory mite in a hybrid grapevine population.

Hortic Res 2019 21;6:87. Epub 2019 Jul 21.

Horticulture Section, School of Integrative Plant Science, Cornell AgriTech, Geneva, NY 14456 USA.

The abundance of predatory phytoseiid mites, , important biological control agents of spider mite pests in numerous crops, is positively influenced by the density of leaf trichomes and tuft-form domatia in vein axils. Identification of the genetic regions controlling both trophic levels could facilitate the improvement of predatory mite habitat in breeding programs. The abundance of and non-glandular trichomes was measured in a segregating F family derived from the cross of the complex hybrid, 'Horizon', with Illinois 547-1 ( B38 ×  B9), finding positive correlation among traits.

[Stenting of calcified iliofemoral venous segment in post-thrombotic syndrome].

Angiol Sosud Khir 2019 ;25(1):82-86

Department of Surgery, Institute of Additional Professional Education, South Ural State Medical University of the RF Ministry of Public Health, Chelyabinsk, Russia.

Stenting of the iliac veins in patients with post-thrombotic syndrome is an intervention associated with a low risk of complications, high primary and secondary patency rates, low incidence of restenosis, leading to a significant decrease in the severity of symptoms of chronic venous disease and a high rate of trophic ulcer healing, as compared with conservative therapy. Unlike subcutaneous veins, the formation of calcinates in deep veins after endured thrombosis is of considerably less frequent occurrence. Described in the article is a clinical case report concerning successful stenting of the iliofemoral venous segment in a female patient presenting with post-thrombotic syndrome, a trophic ulcer of the crus, and the presence of linear calcinosis in the lumen of the iliac veins and common femoral vein.

Key Laboratory for Biomedical Effects of Nanomaterials and Nanosafety , Institute of High Energy Physics, Chinese Academy of Sciences , Beijing 100049 , China.

The physiochemical properties of nanoparticles (NPs), including surface charge, will affect their uptake, transformation, translocation, and final fate in the environment. In this study, we compared the phytoxoxicity and transport behaviors of nano CeO (nCeO) functionalized with positively charged (Cs-nCeO) and negatively charged (PAA-nCeO) coatings. Cucumber seedlings were hydroponically exposed to 0-1000 mg/L of Cs-nCeO and PAA-nCeO for 14 days and the contents, distribution, translocation, and transformation of Ce in plants were analyzed using inductively coupled plasma mass spectrometry, micro X-ray fluorescence (μ-XRF), and X-ray absorption near-edge spectroscopy (XANES), respectively.
