The appearance of fresh meat is a major determinant of its appeal to consumers. Ground beef in retail display oxidizes at a faster rate than whole muscle products;the use of antioxidants to break the radical chain reaction in the oxidation process is an effective method for slowing oxidation. Soybean is a complex matrix with several bioactive compounds, including peptides and proteins, isoflavones, saponins, and other compounds with antioxidant properties. This study was conducted for 1) to evaluate the antioxidant properties of dry soybeans sprouts (DSS) from Glycine max (L.) Merr., MUNASQA?;2) to evaluate quality characteristics of raw beef patties added with dried soybean sprouts at different levels (0.5%, 1% and 2%) and soybean oil as a replacer of fat;and 3) to estimate color changes and lipid oxidation of n3 fortified raw beef under frozen storage. Results showed that dry soybean sprouts had a high level of superoxide dismutase enzyme, high total phenolics and flavonoids content and appreciable vitamin c content. Although reduction power was low, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzthiazoline-6-ulphonic acid) (ABTS) radicals scavenging activity were elevated. When different concentrations of DSS were incorporated to enriched beef patties with soybean oil, the nutritional value was slightly affected, while that n3 and n6 fatty acid content were increased around three twice. The beef patties formulated with 1% of natural antioxidant showed significantly (p < 0.05) better color stability than those without antioxidants. The lipid oxidation was inhibited in all cases, and was strongly effective at 1% concentration of DSS being the reduced percent of thiobarbituric acid reactive substances (TBARS) comparable to butilated hydroxianisole (BHA). The results shown in this research suggest that dry soybeans sprouts could also be used as a cheap natural antioxidant source for meat products.

Investigating local corrosion processes of magnesium alloys with scanning probe electrochemical techniques: A review

Journal of Magnesium and Alloys 2022年第11期10卷 2997-3030页

The study of corrosion of magnesium and its alloys has emerged a hot topic in the applications of lightweight structural materials. The inherently high electrochemical activity of bare magnesium surfaces still lacks a convincing mechanism to describe the observed experimental characteristics, and it has prompted the development of various types of protective coatings with the aim of slowing metal dissolution. In recent years, new instruments and techniques have been developed to study with spatial resolution the local corrosion processes that occur in metallic materials in general, and for magnesium and its alloys in particular, both for bare surfaces and coated. Scanning microelectrochemical techniques, such as local electrochemical impedance spectroscopy(LEIS), scanning electrochemical microscopy(SECM), scanning vibrating electrode technique(SVET), scanning ion-selective electrode technique(SIET) and scanning Kelvin probe(SKP) can provide information about the local electrochemical activity of metallic surfaces. In the present work, the applications of these techniques in corrosion studies of magnesium and its alloys are reviewed. Assessment of corrosion mechanisms, barrier properties of conventional coatings and active corrosion behavior of self-healing coatings are examined. Limitations and future developments in this area are discussed.

Abdominal aortic aneurysm (AAA) is a common degenerative vascular disease with a prevalence up to 8% in males over 60 years of age.1 This is a complex disorder characterized by permanent and focal dilation of abdominal aorta that exceeds at least 50% of the normal diameter. In these patients, the aortic diameter progressively expands boosted by smoking and aging as major risk factors. Unfortunately, aneurysm growth increases the risk of aortic rupture, a life-threatening emergency that carries a mortality rate of 80%. Despite the increasing effort of the scientific community to identify therapeutic strategies for AAA, there are currently no pharmacological tools that ameliorate aneurysm expansion, while the underlying mechanisms involved in this disease are not completely understood.

COVID-19: Feelings Experienced by Nurses, Physiotherapists, and Medical Doctors in a Brazilian Field Hospital

Open Journal of Nursing 2021年第5期11卷 390-406页

Facing critical situations such as the ones triggered by COVID-19 may take healthcare professionals to confront their psychological resources, which may induce a higher stress level. We aimed to understand the feelings experienced by nurses, physiotherapists, and medical doctors in a field hospital dedicated to patients with COVID-19 in the biggest city of Brazil. Methods: We performed a qualitative study in a state field hospital in S?o Paulo city, Brazil, in a sample of 25 volunteer healthcare professionals. Participants answered to a sociodemographic electronic survey and were subjected to an individual semi-structured on-site interview. Results: Participants were mostly female (68%), comprised eight nurses, eight physiotherapists, and nine medical doctors, had an average age of 36.8 years, and were professionally experienced. Speech analysis revealed two thematic categories (related to work and assistance in the pandemic) and 11 subcategories: adaptation to the scenario, stressing experience, psychological support, difficulties with workwear, safety with workwear, non-verbal communication, empathy, patient comfort, outstanding experiences, major challenges, and teamwork. Conclusion: Nurses, physiotherapists, and medical doctors’ experiences while working in the field hospital were permeated by both positive and negative feelings. Those feelings originated directly from the fear of the unknown when dealing with a new disease without well-established scientific evidence, the use of medical workwear for long periods, and communication and environmental difficulties. In contrast, positive feelings, related to teamwork and empathy, arose and overlapped with the difficulties.

AIM: To compare the current capsule and a new prototype at 2 and 4 frames-per-second, respectively, in terms of clinical and therapeutic impact. METHODS: One hundred patients with an indication for capsule endoscopy were included in the study. All procedures were performed with the new device(SB24). After an exhaustive evaluation of the SB24 videos, they were then converted to "SB2-like" videos for their evaluation. Findings, frames per finding, and clinical and therapeutic impact derived from video visualization were analyzed. Kappa index for interobserver agreement and χ2 and Student's t tests for qualitative/quantitative variables, respectively, were used. Values of P under 0.05 were considered statistically ***: Eighty-nine out of 100 cases included in the study were ultimately included in the analysis. The SB24 videos detected the anatomical landmarks(Zline and duodenal papilla) and lesions in more patients than the "SB2-like" videos. On the other hand, the SB24 videos detected more frames per landmark/lesion than the "SB2-like" videos. However, these differences were not statistically significant(P > 0.05). Both clinical and therapeutic impacts were similar between SB24 and "SB2-like" videos(K = 0.954). The time spent by readers was significantly higher for SB24 videos visualization(P 0.05).CONCLUSION: More frames-per-second detect more landmarks, lesions, and frames per landmark/lesion, but is time consuming and has a very low impact on clinical and therapeutic management.

小胶质细胞是大脑的常驻巨噬细胞,通过感知神经元活动并支持突触重塑和可塑性积极促进脑实质的稳态。虽然已有研究表明星形胶质细胞在睡眠中的不同作用,但小胶质细胞在调节睡眠/觉醒周期和白天不同阶段调节突触活动中的作用尚未深入研究。以光作为授时提示,我们研究了用集落刺激因子-1受体拮抗剂PLX5622消除小胶质细胞对雄性小鼠睡眠/觉醒周期和海马突触传递的影响。我们的数据表明,小胶质细胞几乎完全的耗竭会增加NREM睡眠的持续时间并减少海马兴奋性神经传递。由于cx3cr1GFP/GFP小鼠显现与PLX5622处理的小鼠中发现的相同情况,趋化因子fractalkine受体CX3CR1在这些效应中起相关作用。此外,在光照阶段小胶质细胞表达较低水平的cx3cr1;当培养的小胶质细胞受到ATP(一种在睡眠期间释放的嘌呤能分子)的刺激时其cx3cr1表达降低。我们的研究结果表明,小胶质细胞参与调节睡眠,调整其cx3cr1表达以响应光/暗阶段,并以时相依赖性方式调节突触活动。
