Purpose Electron beam computed tomography (EBcT) is a relatively new technolog y that has been used primarily to detect coronary artery calcification in adult patients. EBcT has several potential advantages over traditional cT: (1) fast ac quisition times resulting in less need for sedation, (2) decreased radiation exp osure, and (3) robust software enabling real-time interactive 3-dimensional vi sualization of anatomic relationships. In this series of case reports, the autho rs describe their initial experience with the use of EBcT in pediatric noncardia c imaging. Methods children with a variety of thoracic and abdominal disease pro cesses were evaluated by EBcT. Results All patients underwent EBcT scanning without the need for sedation, and 3-dimensional images of the data sets were rendered in minutes after their acquisition. The diagnostic image s provided equivalent spatial resolution to the multislice cT scanner but withou t motion artifacts and lower radiation exposure. conclusions EBcT is a safe, eff ective, and user-and patient-friendly alternative to traditional cT in the car e of pediatric surgical diseases. The diagnostic yield of EBcT will continue to improve with new technologic advances and clinical experience.

目前家禽正面临着许多挑战，包括禽类饲养对环境的影响、禽类健康和免疫、禽类产品的安全性等问题。试验旨在评价植酸酶和有机酸（单独或组合使用）对肉用公鸡（Ross308）生长性能、营养物质消化率、胫骨灰分、免疫力和肠道形态的影响。试验分为5个处理组，包括阳性对照组（Pc）：饲粮中添加足量的有效磷（起始期和生长期分别添加4．9和4．4g·kg^-1）；阴性对照组（Nc）：饲粮中添加低水平的有效磷（起始期和生长期分别添加3．9和3．4g·kg^-1）；在Nc组饲粮中添加有机酸（sal）0．2％；在Nc组饲粮中添加植酸酶500U·kg^-1饲粮（Phy）；Nc组饲粮中添加有机酸和植酸酶（sal＋Phv）；每个处理5个重复，每个重复20只鸡。在起始期（0—14d）和生长期（15～28d）饲喂玉米一豆粕型基础饲粮，自由采食。试验结果表明，Phy＋Sal组和Nc组分别有最高和最低的体增重（50．80和39．68g·只·d。）、采食量（74．78和64．69g·只·d“）和饲料转化率（1．47和1．63）（P〈0．001）。Nc组对粗蛋白质和乙醚提取物消化率最低（分别为0．7751和0．7949），与对照组相比，Phy组分别提高0．8506和0．8645，Phy＋Sal组分别提高0．8858和0．8561（P〈O．001和P=0．001）。与Nc组肉仔鸡（341．6g·kg^-1）相比，Sal组（374．3g·kg^-1）极显著提高胫骨灰分，但比其他组均低（Pc、Phy和Phy＋Sal）。与Pc组相比，Phy和Phy＋Sal组改善了肉仔鸡十二指肠、空肠和回场的绒毛长度和绒毛长度／隐窝深度。在起始期，与其他组相比，Phy＋Sal组的lgG（2．27）最高（P〈0．001），在生长期其总免疫球蛋白（7．84）和lgG（5．74）也最高（P〈0．001）。研究表明，同时补充植酸酶和有机酸可以提高饲喂低水平有效磷肉仔鸡的生长性能、骨内矿物质、肠道完整性和免疫反应。

Andean high-altitude wetlands are important ecosystems that serve a range of socialecological functions. In the Andes, bofedales, a specific type of peat-producing wetland, are essential for the sustainability of mountain ecosystems and indigenous pastoralist communities. The chucuyo bofedal in northern chile is affected by climatic variability and water extraction for agricultural uses via the Lauca canal. Herders in the local community also actively manage this wetland according to their traditional ecological knowledge to ensure permanent fodder for their animals. In this article, we analyze the annual behavior of the chucuyo bofedal after the wet season. Based on precipitation data, extracted water flows, vegetation vigor from satellite images, and an ethnographic approach, we determined that the bofedal’s productivity was negatively correlated with the amount of precipitation and positively correlated with the surface area of the wetland. However, water extraction via the Lauca channel had no significant relationship with either surface area or vegetation vigor. We identify community practices and traditional ecological knowledge as key elements in the maintenance of these ecosystems. This situation is critical in the context of an aging population and the current pattern of migration out of the region to urban areas. The results provide substantial empirical evidence for future decision-making regarding the conservation of these ecosystems.

Background:To measure angle-to-angle(ATA)and spur-to-spur(STS)distances along six meridians using highresolution swept-source optical coherence tomography(SS-OcT)and to compare those values with horizontal white-to-white(WTW)***:68 eyes from 68 patients were quantitatively assessed with the Anterion SS-OcT(Heidelberg Engineering,Heidelberg,Germany).ATA and STS distances were measured with the SS-OcT’s B-Scan in six cross-sectional images corresponding to the vertical(6-12 o’clock),1-7 o’clock,2-8 o’clock,horizontal(3-9 o’clock),4-10 o’clock and 5-11 o’clock *** was measured horizontally with the device’s infrared camera.A Pearson correlation analysis was carried out to compare ATA and STS distances with ***:The largest values were found for the vertical meridian and the shortest for the 2-8 o’clock meridian,both for ATA and STS *** statistically significant differences were found between WTW,ATA and STS along the horizontal meridian(p>0.1).However,ATA and STS showed statistically significant differences elsewhere,except for the horizontal and the 2-8 o’clock meridians(p>0.05).Moreover,we found that ATA and STS varied significantly depending on the meridian being assessed,except for ATA at 4-10 versus 3-9 o’clock and for STS at 4-10 versus 3-9 o’clock and at 3-9 versus 2-8 o’clock(p>0.1).R^(2) values ranged from 0.49 to 0.75 for ATA and STS at the different meridians,showing the best correlation at 3-9 o’clock meridian(0.64 and 0.75,respectively)and the worst at 6-12 o’clock meridian(R^(2)=0.49 for both ATA and STS).conclusions:ATA and STS distances vary radially,thus showing that the anterior chamber is vertically ***,it is advisable to measure these two distances along the meridian to be used.
