A new method for the direct tracking of in vivo lignin nanocapsules in Eragrostis tef (Poaceae) tissues

Environmental concerns have driven scientists to research new eco-friendly approaches for the preparation of nanosystems. For this purpose, novel bio-polymers have been selected. Among these, one of the most promising is lignin, which is biodegradable and biocompatible. Additionally, lignin is one of the main by-products of the paper industry and can be re-used in nanosystems building. Lignin-based nanosystems could be used in agriculture, to improve the uptake of bioactive compounds, thus avoiding soil pollution. However, the mechanism of penetration in the plant and the route of transportation within the internal plant tissues are unknown and need to be clearly elucidated. Here we present a method of lignin nanocapsules staining and tracking by fluorochrome: Fluoral Yellow 088, which is a well-suited dye for the tracking of lipids and other oil phases. Two different applications were applied: in the first one fourteen-day plants were soaked with fluorescent nanocapsules (fNCs) pure solution and in the second one, Eragrostis tef plants were laid down on blotting paper and soaked with diluted fNCs solution. Wetting the roots of Teff plantlets with the pure fNCs solution resulted in the most efficient way of nanocapsule entrance. The dyeing of lignin nanocapsules allowed us to track them inEragrostis tef plant tissues through microscopic observations. In particular, fNCs were proven to be able to permeate roots, reaching xylem vessels where, through water pressure, they reache...

AbstractIntroduction and hypothesisA systematic survey on the association between childhood nocturnal enuresis (CNE) and adult pelvic floor disorders (PFDs) has not been presented previously. The aim was to describe the prevalence of PFDs and lower urinary tract symptoms in nulliparous women, with or without a history of CNE, at the age of ≥ 5 years.MethodsThis national survey of urinary (UI) and fecal incontinence (FI) and symptoms of pelvic organ prolapse (sPOP) was a random sample of 20,000 nulliparous women aged 25 –64 years conducted in 2014. Women ≥ 5 years of age having CNE were compared w...

Purpose of review This review aims to update the studies involving the treatment of lower urinary tract symptoms (LUTS) in neurogenic patients, published in the last two years. Recent findings Treatment of neurogenic LUTS (NLUTS) patients with β3 adrenoreceptor agonists was investigated in real-life conditions. A randomized controlled trial compared the efficacy of antimuscarinics versus onabotulinum toxin A in neurogenic patients. The use of desmopressin to treat nocturia in multiple sclerosis patients is also reported. The long-term treatment with BontA efficacy, its discontinuation, and possible strategies to ...

Reversible functional inkjet printing is introduced as a new route to paper ‐ and cardboard‐based electronics. Hybrid metal‐polymer nanoparticle inks are combined with tailored paper coats to create conductive structures on low‐cost cardboard substrates without sintering. The conductive particles can be redispersed in liquid, which makes it possible to repair damage s after bending and folding. AbstractConductive inkjet printing with metal nanoparticles is irreversible because the particles are sintered into a continuous metal film. The resulting structures are difficult to remove or repair and prone to cracking. H...
