“…The width on the top and base of footpad skin papillae changed by elevated TEM making them more prone to carry litter and fecal material in between papillae, which consequently causes them to maintain more contact with materials that can cause dermatitis. This field study confirms recent observations reported by DaCosta et al [34] about negative effects of high incubation temperatures on all skin layers of chicken footpads from hatch until 22 d of age.…”

“…Nevertheless, it was pertinent that treatments did have an effect on embryo yolk utilization, impacted some parameters of footpad skin development at hatch and 35 d of age, and influenced (P<0.10) probabilities to observe FPD. This field trial provided more evidence that incubation affects footpad skin development [34] and proper incubation could be important to minimize FPD in poultry species [22].…”

SUMMARYFootpad dermatitis (FPD) is a major animal welfare and economical concern. A field trial was conducted to evaluate the effects of eggshell conductance (G) and incubation temperature profiles (TEM) on duck footpad skin structure at hatch and 35 d of age, and their influence on probability to observe FPD scores under commercial conditions. A total of 10,000 Pekin duck eggs were assigned to 4 treatments, resulting from a combination of two G, reduced and normal, and two TEM, elevated and normal. At hatch, 6 ducklings from each treatment were weighed and footpad skin samples collected for histological processing. The remaining ducklings were placed in a commercial house. At 35 d, 5 drakes and 5 hens from each treatment combination were weighed and classified for FPD using a 3-level scale to determine probabilities to observe each score using logistic regression. Additionally, footpads of 7 ducks per treatment combination were sampled for histological analysis. Data were analyzed as a CRD with 2×2 factorial arrangement of treatments. There were no effects of treatments on BW at hatch and 35 d. High TEM and reduced G increased residual yolk. On footpad skin layer measurements, an interaction effect was observed on dermis length and area and total papillae height at hatch. At 35 d reduced G ducks had more area of epidermis than normal G. Additionally, either elevated TEM or reduced G tended to increase the probability (P<0.10) of having FPD. The stratus corneum was not affected by treatments. In conclusion, G and incubation TEM have an effect on footpad skin structure development during embryo development, and this might be related to FPD in ducks at market age.

“…The DSC curve of Q showed three phase-transition peaks assigned to the water loss (118 °C, endothermal), melting point (305 °C, endothermal), and the initial decomposition process (332 °C, exothermal). [44] In the case of CHITB and CHITQ, broad exothermic peaks (250-395 °C), expressing the overall exothermic effect connected with decomposition, [45] were evident, with ΔH values moving from 464.44 (CHITB) to 475.62 (CHITQ) J g −1 , probably as a consequence of the covalent bond between CHIT and Q determining a more stable polymeric structure.…”

Multifunctional hydrogels based on chitosan–quercetin (CHITQ) conjugate are prepared by a thermo‐induced radical procedure in the presence of N‐isopropylacrylamide (NIPAAm), acrylamide (AAm), and N,N′‐methylenebis(acrylamide) (MEBA). At first, quercetin (Q) is grafted onto chitosan backbone with a functionalization degree of 275 mg of Q per gram of conjugate, as calculated by 1H‐NMR analyses to impart antioxidant properties to the polysaccharide. Then, a pH and temperature sensitive hydrogel was obtained by involving CHITQ and NIPAAm in the polymerization reaction. The accessibility of phenolic moieties is modified in response to the hydrogel swelling/deswelling, as confirmed by antioxidant tests performed at different temperatures. Dual stimuli‐responsive hydrogels are proposed for the delivery of caffeine as model drug. The release profiles of caffeine depict a system particularly performing as on/off device at acidic pH with excellent applicability prospects.

Additive manufacturing is an emerging technology that brings several opportunities to the manufacturing industry. Therefore, research in this arena on current and future developments is required to make strategic decisions. Under this context, the goal of this research is to develop a patent analysis on additive manufacturing. Keyword-patent analysis is performed to identify the most important organizations, countries, inventors, and technology areas through International Patent Classifications (IPCs) of the additive manufacturing industry. Results show that there is an increase on additive manufacturing research, particularly in 2013 and 2014. The main areas of research are focused on shaping of plastics and after-treatment of shaped products and working metallic powder and manufacture articles from this material. Moreover, the analysis indicates that leading countries on additive manufacturing research are United States, Great Britain and Switzerland. Additionally, top three companies on this area are: Stratasys Inc. (USA), United Technologies Corp. (USA) and Alstom Technology LTD (Switzerland). Its recent research inventions were identified in this study. The main contribution of this research is to offer a template for analysis in other industries, but it also brings valuable insights to decision makers interested in recent patent efforts developed for the advancement of additive manufacturing.
