The use of productive cultivars with adaptability and stability and less demanding to fungicide use are critical to the sustainability of production factors. The objective of this work was to determine the per se performance of white oat cultivars and parameters of adaptability and stability on yield and grain quality in the proposition of cultivars more responsive in reducing the use fungicide. The study was conducted in Augusto Pestana, RS, Brazil, between the years 2010 and 2013. The experimental design was randomized blocks with six replicates, three with and three without fungicide. The study evaluated 14 white oat cultivars for yield and industrial capability. The white oat cultivars FAEM 4 Carlasul and URS Corona indicate high grain yield with stability and general adaptability, independent of chemical control. The cultivar URS Corona shows together high yield and thousand grain weight and hectoliter with general adaptability and stability in the absence of fungicide. Although no stability has been detected in industrial yield without the use of fungicides, cultivars of URS Charrua, URS Corona and URS Taura show high means with general adaptability.

Background Xylanase and β-glucanase combination(XG) hydrolyzes soluble non-starch polysaccharides that are anti-nutritional compounds. This study aimed to evaluate the effects of increasing levels of XG on intestinal health and growth performance of nursery *** Forty pigs(6.5 ± 0.4 kg) were assigned to 5 dietary treatments and fed for 35 d in 3 phases(11, 9, and 15 d, respectively). Basal diets mainly included corn, soybean meal, and corn distiller's dried grains with solubles, contained phytase(750 FTU/kg), and were supplemented with 5 levels of XG at(1) 0,(2) 280 TXU/kg xylanase and 125 TGU/kg β-glucanase,(3) 560 and 250,(4) 840 and 375, or(5) 1,120 and 500, respectively. Growth performance was measured. On d 35, all pigs were euthanized and jejunal mucosa, jejunal digesta, jejunal tissues, and ileal digesta were collected to determine the effects of increasing XG levels and XG intake on intestinal *** Increasing XG intake tended to quadratically decrease(P = 0.059) viscosity of jejunal digesta(min: 1.74 m Pa·s at 751/335(TXU/TGU)/kg). Increasing levels of XG quadratically decreased(P < 0.05) Prevotellaceae(min: 0.6% at 630/281(TXU/TGU)/kg) in the jejunal mucosa. Increasing XG intake quadratically increased(P < 0.05) Lactobacillaceae(max: 40.3% at 608/271(TXU/TGU)/kg) in the jejunal mucosa. Increasing XG intake quadratically decreased(P < 0.05) Helicobacteraceae(min: 1.6% at 560/250(TXU/TGU)/kg) in the jejunal mucosa. Increasing levels of XG tended to linearly decrease(P = 0.073) jejunal Ig G and tended to quadratically increase(P = 0.085) jejunal villus height to crypt depth ratio(max: 2.62 at 560/250(TXU/TGU)/kg). Increasing XG intake tended to linearly increase the apparent ileal digestibility of dry matter(P = 0.087) and ether extract(P = 0.065). Increasing XG intake linearly increased(P < 0.05) average daily *** A combinational use of xylanase and β-glucanase would hydrolyze the non-starch polysaccharides fractions, positively

Chitin powder and chitin-aerogel were prepared from shrimp wastes and used to uptake Y^(3+)from aqueous solutions and concentrate this rare earth element from phosphogypsum(PG).Chitin aerogel displays a specific surface area of 945 m^(2)/g,while chitin powder is 3.6 m^(2)/g,which largely influences its adsorption *** the adsorption in synthetic solutions,the effect of pH on Y^(3+)removal is strong for chitin powder *** contrast,no big pH influence was detected for chitin *** interactions and chelation can highlight the proposed mechanism of Y^(3+)on chitin adsorbents for the powder and ***,in addition to these interactions,pore filling/pore diffusion is the main mechanism of Y^(3+)removal in the chitin *** aerogel is efficient in concentrating 8 times the Y^(3+)from PG,a very complex *** complex chitin aerogel-Y^(3+)can be a secondary source of rare earth elements for other applications.

Background: Prostate cancer ranks as the second most prevalent malignancy in men, with treatment strategies ranging from observation to various interventions. Radical prostatectomy is a common approach, aiming for a cure, and the technique for vesico-urethral anastomosis varies, employing separate or continuous stitches. However, a consensus on the optimal technique is lacking. This study aims to compare vesico-urethral anastomosis techniques (separate vs. continuous stitches) in laparotomy-based radical prostatectomies, evaluating peri and postoperative outcomes. Materials and Method: A retrospective analysis of 140 patients’ medical records yielded 86 eligible cases, divided into two groups based on anastomosis technique. Both groups underwent surgery at the same urology center between 2016 and 2019, with a follow-up period exceeding 12 months. Pre-operative characteristics were statistically similar between groups. Results: Perioperative complication rates did not significantly differ between the two techniques (p > 0.99). However, the continuous stitch group experienced a 20-minute longer procedure time (p 0.05), patients with continuous stitches had 2.5 times higher diaper usage at twelve months (p Conclusion: This research suggests that vesico-urethral anastomosis with separate stitches yields superior results in laparotomy-based radical prostatectomies compared to continuous stitches, demonstrating benefits in surgical time, hospital stay, sentinel drain duration, stenosis rates, and long-term urinary incontinence outcomes.
