Background In March 2021, the United States Food and Drug Administration (FDA) safety communication cautioned against the use of acellular dermal matrix (ADM) products in breast reconstruction and reiterated that the FDA does not approve ADM use in breast surgery. This study aims to assess the safety of ADM use in breast reconstruction. Methods Women who underwent ADM and non-ADM assisted tissue expander (TE)- based breast reconstruction were identified using the National Surgical Quality Improvement Program database (2012–2019). Trends of ADM use over time, and 30-day outcomes of surgical site infection (SSI), dehiscence, and unplanned reoperation were assessed. Results Of the 49,049 TE-based breast reconstructive cases, 42.4% were ADM assisted and 57.6% non-ADM assisted. From 2012 to 2019, the use of ADM increased from 26.1 to 55.6% (relative risk [RR] ¼1.10; p<0.01). Higher rates of SSI (3.9 vs. 3.4%; p¼0.003) and reoperation (7.4 vs. 6.0%; p<0.001) were seen in the ADM cohort. There was no significant difference seen in dehiscence rates (0.7 vs. 0.7%; p¼0.73). The most common reoperation within 30 days for the ADM group (17.6%) was removal of TE without insertion of implant (current procedural terminology: 11,971). ADM-assisted breast reconstruction was associated with increased relative risk of SSI by 10% (RR¼1.10, confidence interval [CI]: 1.01–1.21; p¼0.03) and reoperation by 15% (RR¼1.15, CI: 1.08–1.23; p<0.001). Conclusions ADM-assisted breast reconstruction more than doubled from 2012 to 2019. There are statistically higher complication rates of SSI (0.5%) and reoperation (1.4%) with ADM use in TE-based breast reconstruction, suggesting that reconstruction without ADM is safe when comparing immediate postoperative outcomes.
Ingestive Behavior of Lambs Confined in Individual and Group Stalls
Filho, A. Eustaquio,Carvalho, G.G.P.,Pires, A.J.V.,Silva, R.R.,Santos, P.E.F.,Murta, R.M.,Pereira, F.M. Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.2
The experiment was conducted to evaluate the ingestive behavior of lambs confined in individual and group stalls. We used thirty-four lambs in their growing phase, aged an average of three months, with mean initial live weight of $17.8{\pm}5.2$ kg. They were allotted in a completely randomized design with 24 animals kept in individual stalls and 10 animals confined as a group. The experiment lasted for a total of 74 days, and the first 14 days were dedicated to the animals' adaption to the management, facilities and diets. The data collection period lasted 60 days, divided into three 20-d periods for the behavior evaluation. The animals were subjected to five days of visual observation during the experiment period, by the quantification of 24 h a day, with evaluations on the 15th day of each period and an interim evaluation consisting of two consecutive days on the 30th and 31st day of the experiment. The animals confined as a group consumed less (p<0.05) fiber. However, the animals confined individually spent less (p<0.05) time on feeding, rumination and chewing activities and longer in idleness. Therefore, the lower capacity of lambs confined in groups to select their food negatively affects their feeding behavior.

<P><B>Summary</B></P><P>Interspecific hybridization is a significant evolutionary force as well as a powerful method for crop breeding. Partial substitution of the AA subgenome in <I>Brassica napus</I> (A<SUP>n</SUP>A<SUP>n</SUP>C<SUP>n</SUP>C<SUP>n</SUP>) with the <I>Brassica rapa</I> (A<SUP>r</SUP>A<SUP>r</SUP>) genome by two rounds of interspecific hybridization resulted in a new introgressed type of <I>B.?napus</I> (A<SUP>r</SUP>A<SUP>r</SUP>C<SUP>n</SUP>C<SUP>n</SUP>). In this study, we construct a population of recombinant inbred lines of the new introgressed type of <I>B.?napus</I>. Microsatellite, intron‐based and retrotransposon markers were used to characterize this experimental population with genetic mapping, genetic map comparison and specific marker cloning analysis. Yield‐related traits were also recorded for identification of quantitative trait loci (QTLs). A remarkable range of novel genomic alterations was observed in the population, including simple sequence repeat (SSR) mutations, chromosomal rearrangements and retrotransposon activations. Most of these changes occurred immediately after interspecific hybridization, in the early stages of genome stabilization and derivation of experimental lines. These novel genomic alterations affected yield‐related traits in the introgressed <I>B.?napus</I> to an even greater extent than the alleles alone that were introgressed from the A<SUP>r</SUP> subgenome of <I>B.?rapa</I>, suggesting that genomic changes induced by interspecific hybridization are highly significant in both genome evolution and crop improvement.</P>

<P>The Pecorans (higher ruminants) are believed to have rapidly speciated in the Mid-Eocene, resulting in five distinct extant families: Antilocapridae, Giraffidae, Moschidae, Cervidae, and Bovidae. Due to the rapid radiation, the Pecoran phylogeny has proven difficult to resolve, and 11 of the 15 possible rooted phylogenies describing ancestral relationships among the Antilocapridae, Giraffidae, Cervidae, and Bovidae have each been argued as representations of the true phylogeny. Here we demonstrate that a genome-wide single nucleotide polymorphism (SNP) genotyping platform designed for one species can be used to genotype ancient DNA from an extinct species and DNA from species diverged up to 29 million years ago and that the produced genotypes can be used to resolve the phylogeny for this rapidly radiated infraorder. We used a high-throughput assay with 54,693 SNP loci developed for Bos taurus taurus to rapidly genotype 678 individuals representing 61 Pecoran species. We produced a highly resolved phylogeny for this diverse group based upon 40,843 genome-wide SNP, which is five times as many informative characters as have previously been analyzed. We also establish a method to amplify and screen genomic information from extinct species, and place Bison priscus within the Bovidae. The quality of genotype calls and the placement of samples within a well-supported phylogeny may provide an important test for validating the fidelity and integrity of ancient samples. Finally, we constructed a phylogenomic network to accurately describe the relationships between 48 cattle breeds and facilitate inferences concerning the history of domestication and breed formation.</P>

This article presents an integrated approach for localized necking and failure prediction in sheet metal forming processes, based on the coupling between the anisotropic damage evolution law proposed by Lemaitre [1] and the modified maximum force criterion (MMFC) proposed by Hora et al [2]. To illustrate the essential features of the coupled approach, an aluminum alloy has been selected and numerical predictions have been compared with experimental forming limits, obtained for both linear strain paths evolutions. Numerical results show that the introduction of the softening behavior, caused by the increase of damage, into the necking criterion can play a significant role in triggering local necking, providing an improved prediction of the necking occurrence together with the capability of performing calculations of limit strains when they are governed by fracture rather than by local necking.
From Single to Many-Objective PID Controller Design using Particle Swarm Optimization
Hélio Freire,P. B. Moura Oliveira,E. J. Solteiro Pires 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.2
Proportional, integrative and derivative (PID) controllers are among the most used in industrial controlapplications. Classical PID controller design methodologies can be significantly improved by incorporatingrecent computational intelligence techniques. Two techniques based on particle swarm optimization (PSO) algorithmsare proposed to design PI-PID controllers. Both control design methodologies are directed to optimizePI-PID controller gains using two degrees-of-freedom control configurations, subjected to frequency domain robustnessconstraints. The first technique proposes a single-objective PSO algorithm, to sequentially design a twodegrees-of-freedom control structure, considering the optimization of load disturbance rejection followed by setpointtracking optimization. The second technique proposes a many-objective PSO algorithm, to design a twodegrees-of-freedom control structure, considering simultaneously, the optimization of four different design criteria. In the many-objective case, the control engineer may select the most adequate solution among the resulting optimalPareto set. Simulation results are presented showing the effectiveness of the proposed PI-PID design techniques, incomparison with both classic and optimization based methods.
Diets Based on Sugar Cane Treated with Calcium Oxide for Lambs
Carvalho, G.G.P.,Garcia, R.,Pires, A.J.V.,Silva, R.R.,Detmann, E.,Filho, A. Eustaquio,Ribeiro, L.S.O.,Carvalho, L.M. Asian Australasian Association of Animal Productio 2013 Animal Bioscience Vol.26 No.2
This experiment was conducted to evaluate the intake, nutrient apparent digestibility and the effect of total collection days (two and four days) on apparent digestibility estimates for lambs fed diets containing sugar cane treated with calcium oxide (CaO). Eight Santa In$\hat{e}$s castrated male lambs with a $16.6{\pm}1.8$ kg body weight were used. The lambs were distributed in two $4{\times}4$ Latin squares, with four experimental periods of 14 d each. The animals were kept in 1.2 $m^2$ individual pens, and the intake and digestibility evaluations were performed during the last four days of each period. The diets were formulated to be isonitrogenous, containing 14% crude protein (CP), and presenting 70% sugar cane treated with 0, 0.75, 1.5 or 2.25% of CaO (as-fed basis), corrected with 1% urea, and 30% concentrate. The sugar cane with added CaO was chopped, treated, and offered to the animals after 24 h of storage. The sugar cane with CaO increased the DM, OM, CP, NDF, NDFap, TC, NFCap and TDN intake (kg/d), when compared to natural sugar cane, and produced the same intake expressed as a percentage of body weight (% BW). The NFCap digestibility of the CaO-treated sugar cane was inferior to the NFCap digestibility in natural sugar cane. There was a linear increase in the DM intake with the CaO-added sugar cane, but the DM and NDF digestibility and the TDN content decreased linearly. The chemical treatment of sugar cane with CaO increases the intake but does not improve the nutrient digestibility. Two days of total fecal collection were found to be sufficient to estimate the total apparent digestibility in lambs.
