Objective: This study aimed to evaluate the replacement of degummed soybean oil (DSO) by acid soybean oil (ASO) in diets with or without the inclusion of emulsifier on broiler performance, relative organ weight, lipase activity, intestinal morphometry, and nutrient digestibility. Methods: A total of 704 1-day-old male broiler chicks were allotted to a 2×2 completely randomized factorial design (with or without emulsifier × two lipid sources [ASO and DSO]), with eight replicates and 22 birds each. The metabolizable energy level in diets with emulsifier was reduced by 40 kcal/kg from 1 to 21 d and 50 kcal/kg from 22 to 49 d. Results: Broilers fed diets containing ASO without emulsifier had higher (p = 0.005) weight gain than DSO-fed animals and with the inclusion of emulsifier had worse (p = 0.018) feed conversion ratio (FCR). Birds fed diets with emulsifier worsened FCR regardless of lipid source from 1 to 21 days (p = 0.006) and from 1 to 49 days (p = 0.0002). There was an increase (p = 0.026) in the relative pancreas weight, at 14 days, in birds fed diets containing ASO. Lipase activity and morphometry of the duodenum and jejunum, at 14 and 21 days, were not affected (p>0.05). The dietary inclusion of emulsifier improved the digestible energy (p = 0.053) in the presence of ASO. For the digestibility coefficients (gross energy, crude protein, and mineral matter), no interference was observed (p>0.05). Conclusion: The inclusion of emulsifier to energy-restricted diet with ASO maintained broiler performance in the first week, but worsened FCR in subsequent phases. The ASO can be considered as an alternative lipid source to DSO and does not interfere with the morphophysiological characteristics and performance of broilers. The combination of ASO and emulsifier increased the digestible energy content by 6.2%.

Átila Vinícius Vitor Nobre,Mário Taba Júnior,Alfredo Ribeiro Silva,Sérgio Luís Scombatti de Souza,Ana Carolina Fragoso Motta 대한피부과학회 2022 Annals of Dermatology Vol.34 No.4

Focal dermal hypoplasia (FDH), also known as Goltz syndrome, consists of an unusual genodermatosis that affects tissues of ectodermal and mesodermal origin and various or- gans and systems, especially skin, bones, eyes, and oral cavity. While systemic manifesta- tions of FDH have been well documented, the oral manifestations have not been extensively discussed. We present a 22-year-old female patient with history of FDH that showed a variety of systemic and oral manifestations. FDH was diagnosed at birth based on cutane- ous alterations. Extra and intraoral examination showed facial asymmetry, lip and perioral atrophy, upper lip papilloma, malocclusion, enamel hypoplasia, and gingival hyperplasia. Mucosal lesions, periodontal diseases, and malocclusion were treated by oral surgery, peri- odontal therapy and orthodontic treatment, respectively. Although FDH is an uncommon syndrome, health professionals should be aware of its systemic and oral manifestations to establish an early diagnosis and adequate treatment.

Purpose: The aim of this study was to evaluate whether the presence of an intrauterinehematoma (IUH) on an early pregnancy ultrasound scan showing a live fetus was related toadverse perinatal outcomes. Methods: We performed a retrospective cohort study to evaluate pregnant women whounderwent an ultrasound examination in early pregnancy, between 6 weeks 0 days and 10weeks 6 days. We compared the perinatal outcomes between women with and without firsttrimester IUH using the Mann-Whitney and Fisher exact tests. Furthermore, we performed astepwise regression analysis to identify possible predictors of miscarriage among maternalcharacteristics, ultrasound parameters, and IUH. Results: During the study period, data from 783 pregnancies were included, and the incidence ofIUH was 4.5% (35 of 783). We observed a higher proportion of miscarriage following the scan(28.6% vs. 10%, P=0.003) and a larger yolk sac diameter during the scan (4.8 mm vs. 3.8 mm,P<0.001) in the pregnant women with first-trimester IUH. There was no significant differenceregard the prevalence of low birth weight (LBW; P=0.091), very LBW (P=0.370), or extremelyLBW (P=0.600) between cases with IUH and without IUH, the cesarean section rate (68% vs. 81%, P=0.130), preterm delivery (16% vs. 16%, P>0.999), or the incidence of first-trimestervaginal bleeding (31% vs. 20%, P=0.130). Moreover, heart rate (HR) was the only variable thatpredicted miscarriage with statistical significance (P=0.017). Conclusion: Women with first-trimester IUH had a higher risk of miscarriage after the ultrasoundscan. HR was the only variable that predicted miscarriage with statistical significance.

Tunnel access for ridge augmentation: A review

D’Albis Giuseppe,D’Albis Vincenzo,Cesário de Oliveira Júnior Jonhson,D’Orazio Fabrizio 대한치과이식(임프란트)학회 2021 The Korean Academy of Implant Dentistry Vol.40 No.2

In traditional bone regeneration, the periosteal layer of the flap must be released to achieve tension-free primary wound closure. Several minimally invasive tunnel techniques have been introduced to augment the bone volume for prosthetic-driven implant placement, thus minimizing tissue trauma and patient morbidity. This literature review aimed at analyzing the available literature on ridge augmentation with a lateral tunnel access approach, and detailed the surgical protocols, materials, advantages, indications for use, disadvantages, and complications. The Medline and PubMed medical databases were searched for reports published between 2005 and March of 2021. Seventeen articles describing minimally invasive tunnel techniques for ridge augmentation were identified. Preservation of the integrity of the periosteum has been found to be the determining factor in reducing postoperative pain and improving wound vascularization. Studies have reported encouraging data on the bone volume obtained for implant-prosthetic rehabilitation using this technique.

Determination of kinetic parameters for the sisal residue pyrolysis through thermal analysis

Daniel Bemmuyal Passos Santos,Marcos Fábio de Jesus,José Mário Ferreira Júnior,Carlos Augusto de Moraes Pires 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.109 No.-

Determining the kinetics of biomass degradation by thermogravimetry is complex due to the existence ofnumerous parallel and consecutive reactions. The individual use of models available in the literature haslimitations regarding the applicability of the data due to high adjustment errors or lack of process information. Thus, a new procedure was proposed to determine the degradation kinetics of sisal residue, atheating rates of 20–80 C/min and inert atmosphere. First, the reaction order was determined by thefit model for each heating rate, resulting in approximate values. Then, the activation energy and thepre-exponential factor were determined by free models (Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose,and Friedman). These models were validated from the experimental data of conversion and temperature,together with the calculated kinetic parameters. Friedman’s model was the best fit. Finally, the errorsobtained are compatible with those in the literature, indicating that this procedure can be used in kineticsinvolving biomass pyrolysis.

Influence of Protein and Energy Level in Finishing Diets for Feedlot Hair Lambs: Growth Performance, Dietary Energetics and Carcass Characteristics

Rios-Rincon, F.G.,Estrada-Angulo, A.,Plascencia, A.,Lopez-Soto, M.A.,Castro-Perez, B.I.,Portillo-Loera, J.J.,Robles-Estrada, J.C.,Calderon-Cortes, J.F.,Davila-Ramos, H. Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.1

Forty-eight Pelibuey${\times}$Katahdin male intact lambs ($23.87{\pm}2.84$ kg) were used in an 84-d feeding trial, with six pens per treatment in a $2{\times}2$ factorial design arrangement. The aim of the study was to evaluate the interaction of two dietary energy levels (3.05 and 2.83 Mcal/kg ME) and two dietary protein levels (17.5% and 14.5%) on growth performance, dietary energetics and carcass traits. The dietary treatments used were: i) High protein-high energy (HP-HE); ii) High protein-low energy (HP-LE); iii) Low protein-high energy (LP-HE), and iv) Low protein-low energy (LP-LE). With a high-energy level, dry matter intake (DMI) values were 6.1% lower in the low-protein diets, while with low-energy, the DMI values did not differ between the dietary protein levels. Energy levels did not influence the final weight and average daily gain (ADG), but resulted in lower DMI values and higher gain efficiencies. No effects of protein level were detected on growth performance. The observed dietary net energy (NE) ratio and observed DMI were closer than expected in all treatments and were not affected by the different treatments. There was an interaction (p<0.03) between energy and protein level for kidney-pelvic and heart fat (KPH), KPH was higher in lambs fed high energy and high protein diet but not in high energy and low protein diet. The KPH was increased (20.2%, p = 0.01) in high-energy diets, while fat thickness was increased (21.7%, p = 0.02) in high-protein diets. Therefore, it is concluded that dietary energy levels play a more important role in feed efficiency than protein levels in finishing lambs with a high-energy diet (>2.80 Mcal/kg ME). Providing a level of protein above 14.5% does not improves growth-performance, dietary energetics or carcass dressing percentage.

Cerebral Hemodynamics in Premature Infants

Christopher J. Rhee,Danielle R. Rios,Jeffrey R. Kaiser,Ken Brady 대한신생아학회 2018 Neonatal medicine Vol.25 No.1

Extremely low birth weight infants remain at increased risk of intraventricular hemorrhage from the fragile vascular bed of the germinal matrix; the roles of hypotension (ischemia) and reperfusion (hyperemia) in the development of intraventricular hemorrhage are still debated. Cerebrovascular pressure autoregulation protects the brain by maintaining constant cerebral blood flow despite changes in blood pressure. The ontogeny of cerebrovascular pressure autoregulation has not been well established and uncertainty remains about the optimal arterial blood pressure required to support brain perfusion. Another important aspect of premature cerebral hemodynamics is the critical closing pressure––the arterial blood pressure at which cerebral blood flow ceases. Interestingly, in premature infants, the critical closing pressure approximates the mean arterial blood pressure. Often in this unique population, cerebral blood flow occurs only during systole when the diastolic arterial blood pressure is equal to the critical closing pressure. Moreover, the diastolic closing margin, a metric of cerebral perfusion that normalizes diastolic arterial blood pressure to the critical closing pressure, may be a better measure than arterial blood pressure for defining cerebral perfusion in premature infants. Elevated diastolic closing margin has been associated with intraventricular hemorrhage. This review summarizes the current state of understanding of cerebral hemodynamics in premature infants.
