This study evaluated the effects of globin and spray-dried porcine plasma (SDPP) on growth performance, digestibility, nitrogen retention, energy retention efficiency (ERE) and intestinal morphology of broiler chickens. A total of 336-day-old male broiler chickens were reared from 1 to 40 days of age and fed 3 diets (8 replicates/diet, 14 birds/replicate) during 3 feeding phases starter (1-12 days), grower (12-25 days) and finisher (25-40 days). Isonitrogenous diets were formulated by replacing gluten protein isolate contained in the control diet (C diet) with 2% (starter) or 1% (grower and finisher) spray-dried porcine plasma in the plasma diet (SDPP diet). The globin diet (G diet) was obtained by adding globin on the top of C diet at a dose of 0.08% for the whole rearing period. Total tract apparent digestibility (aD), nitrogen retention and ERE were assessed during the three growing phases. At 12  and 40 days of age, one bird per pen was slaughtered to sample gut, liver, spleen and bursa of Fabricius for histomorphological investigations. The SDPP diet increased body weights of chickens at 12 (+60 g; p  less then  .001), 25 (+101 g; p  less then  .001) and 40 days (+130 g; p = .018) of age compared to C and G diets. Also SDPP improved crude protein aD (+9.7%) and ERE (+12.3%) during the starter phase (p  less then  .001). Dietary globin and SDPP inclusion did not affect either the gut morphology or the histopathological findings in birds at 12 and 40 days of age, despite a numerical (+6.90% and +7.40% respectively) villus height improvement in the SDPP group. Overall, these results confirm that dietary supplementation with SDPP and, to a lesser extent, with globin can improve growth performance and dietary protein and energy utilization in broiler chickens without effect on gut functionality. © 2020 Blackwell Verlag GmbH.Photodynamic therapy (PDT) exhibits great potential for cancer therapy, but still suffers from nonspecific photosensitivity and poor penetration of photosensitizer. Here, a smart perylene monoimide-based nanocluster with enzyme-triggered disassembly is reported as an activatable and deeply penetrable photosensitizer. A novel carboxylesterase (CE)-responsive tetrachloroperylene monoimide (P1) was synthesized and assembled with folate-decorated albumins into a nanocluster ( FHP ) with a diameter of ~100 nm. Once P1 is hydrolyzed by the tumor-specific CE, FHP  disassembles into ultrasmall nanoparticles (~10 nm), facilitating the deep tumor penetration of FHP . Furthermore, such enzyme-triggered disassembly of FHP  leads to enhanced fluorescence intensity (~8-fold) and elevated singlet oxygen generation ability (~4-fold), enabling in situ near-infrared fluorescence imaging and promoted PDT. FHP  permits remarkable tumor inhibition in vivo  with minimal side effects through imaging-guided, activatable, and deep PDT. This work confirms that this cascaded multifunctional control via enzyme-triggered molecular disassembly is an effective strategy for precise cancer theranostics. © 2020 WILEY-VCH Verlag GmbH & Co.

The combination of gelatin films and stem cells could further accelerate the skin regeneration. Although polysaccharide modification can improve the mechanical property and biological activity of gelatin films, information about the stability and cellular affinity is still limited. This study investigated the influence of polysaccharides on the stability and cellular affinity of gelatin films. Two kinds of gelatin-polysaccharide composite films, including gelatin-hyaluronic acid (G-HA) and gelatin-chitosan (G-CS), were prepared in this study. selleck compound It was found that G-HA composite film had better short-term and long-term stability compared with G-CS composite film. And G-HA composite film also had better biological safety than G-CS film. Moreover, the surface of G-HA composite film supported the adhesion and growth of human umbilical cord Wharton's jelly-derived mesenchymal stem cells (WJ MSCs) better than G-CS film surface. These data illustrated that G-HA composite film has better stability and cellular affinity compared with G-CS film, which could be considered a promising delivery system of stem cells for further in vivo studies. Therefore, this work would be very helpful to optimize the preparation of gelatin-polysaccharide composite films. This article is protected by copyright. All rights reserved.

METHODS Thirty-five people were in the Parkinson's disease group (PDG; 12 women, 62.4 ± 11.0 years, 77.9 ± 15.6 kg, 166.5 ± 11.0 cm, 27.9 ± 3.8 kg/m2 , 1.9 ± 0.5 Hoehn & Yahr) and 32 were in the old adults group (OAG; 13 women, 69.5 ± 6.0 years, 74.2 ± 12.3 kg, 165.0 ± 8.3 cm, 27.2 ± 4.0 kg/m2 ). The static balance was measured on a force platform, three 30-s trials in four conditions feet side-by-side (FSBS) and semi-tandem stance (ST) positioning, eyes open (EO) and eyes closed (EC). The total sway path length (SPL), sway area (SA), anterior-posterior (APSR) and medial-lateral (MLSR) sway range of the centre of pressure were obtained. Dynamic balance was assessed using the timed-up-and-go test (TUG). For comparison between groups and repeated-measures, a mixed-design ANOVA was carried out and the Mann-Whitney U test to compare TUG between groups. The significance level was set at p ≤ .05. RESULTS Between groups, PDG presented higher mean values for SPL, APSR and SA in feet side-by-side eyes open compared to the OAG, for SPL in feet side-by-side eyes closed, for SPL and SA in STEO. For repeated-measures, both groups had higher mean values in the EC condition compared to EO and MLSR compared to APSR. No significant difference was found between groups for TUG. CONCLUSION Balance disorders are found early in people with Parkinson's disease compared to healthy older adults. Thus, Parkinson's disease seems to advance the process of alterations in the postural control system. © 2020 John Wiley & Sons, Ltd.BACKGROUND Keloids are firm, fibrous nodules that form on an individual's skin and are associated with difficult symptoms as well as high recurrence rates. This study aims to improve the surgical techniques that reduce local tension after surgical excision of keloids as well as applying adjuvant radiotherapy to suppress scar formation. METHODS A total of 58 patients aged between 21 to 76 received surgical incision of keloid and immediate post-operation low-dose radiotherapy. All patient follow-ups were performed at the out-patient department. Any sign of a keloid at the incision site was defined as treatment failure or keloid recurrence, regardless of the size. RESULTS At a median follow-up of 22 months, the overall recurrence for all lesions was 8.6%, which in improved compared with previous study. In addition, all incisions performed during surgeries were healed and no signs of necrosis or the development of ulcers was observed. CONCLUSION Our study suggest that this combined therapy provides excellent local control of keloids and shows promise for future therapy. This article is protected by copyright. All rights reserved.

However, to date this technique has been limited almost exclusively to first row transition metals. In this work, we present an extension of Kβ XES (in both the 4p-1s and valence-to-1s [or VtC] regions) to the second transition row by performing a detailed experimental and theoretical analysis of the Molybdenum emission lines. It is demonstrated in this work that Kβ2 lines are dominated by spin state effects, while VtC XES of a 4d transition metal provides access to metal oxidation state and ligand identity. An extension of Mo Kβ XES to nitrogenaserelevant model complexes shows that the method is sufficiently sensitive to act as a spectator probe for redox events that are localized at the Fe atoms. Mo VtC XES thus has promise for future applications to nitrogenase, as well as a range of other Mo-containing biological cofactors. Further, the clear assignment of the origins of Mo VtC XES features opens up the possibility of applying this method to a wide range of second metals, thus providing chemists with a site specific tool for the elucidation of 4d transition metal electronic structure. © 2020 WILEY-VCH Verlag GmbH & Co.

Subsequently, the overall water splitting was performed in 1 M KOH solution by employing Co9S8-Ni3S2/NF as both the anode and cathode electrodes, where the system required only 1.49, 1.60 and 1.69 V to deliver the current densities of 10, 25, and 50 mA cm-2, respectively. Comparison of the activity of Co9S8-Ni3S2/NF with the state-of-the-art Pt/C and RuO2 coated on NF displays an enhanced performance for Co9S8-Ni3S2/NF both in the half-cell as well as in the full cell, emphasizing the significance of the present work.  Overall, the activity modulation achieved in the present case is attributed to the presence of open-pore morphology of the as formed nanoflowers of Co9S8-Ni3S2 on NF and the simultaneous presence of the surface Co(OH)2 along with the highly conducting Co9S8-Ni3S2 core which facilitates the adsorption of the reactants and subsequently its conversion into the gases products during water electrolysis. © 2020 WILEY-VCH Verlag GmbH & Co.

OBJECTIVE We sought to analyze the value of the immunodeficiency scoring index (ISI) in predicting lower respiratory tract disease (LRTD) progression and mortality in a prospective cohort of consecutive adult (> 16 years) allo-HSCT recipients with EvRh infection from December 1 2013 to December 1 2019 at two Spanish transplant centers. RESULTS We included 234 allo-HSCT recipients with 383 EvRh episodes. Out of 383 EvRh episodes, 98 (25%) had LRTD. Multivariate logistic regression analysis identified three independent factors associated with LRTD progression Ig G less then 400 mg/dl, community-acquired respiratory virus (CARV) co-infection and high-risk ISI. Inclusion of Ig G levels and CARV co-infection in the ISI improved its performance by significantly increasing the area under the receiver operator characteristic curve (AUROC) from 0.643 to 0.
