在本教程综述中,我们重新阐述和表达了镧系离子间无辐射能量传递(ET)速率的理论形式,并且强调了考虑镧系离子本身特异性所引发的与Förster和Dexter理论不同之处。所给出的表达式遵循了Judd-Ofelt的4f-4f跃迁理论框架之下的Kushida方法,并计入了如下电多极机制:偶极-偶极(W_(d-d))、偶极-四极(W_(d-q))和四极-四极(W_(q-q))。更为重要的是,当前的机制也扩展包括了交换(W_(ex))和磁偶极子-磁偶极子(W_(md-md))作用,并经过改进进一步包含了屏蔽效应以及给出了F因子(费米黄金规则中的态密度)的解析表达式。与Kushida的原始方法类似,我们只考虑了强制电偶极子(FED)对Judd-Ofelt强度参数的贡献,并细节性地讨论了磁偶极-磁偶极相互作用的选择定则以及相关矩阵元的计算。此外,我们还以Tb(Ⅲ)-Eu(Ⅲ)和Yb(Ⅲ)-Er(Ⅲ)的能量传递速率计算为例,逐步展示了计算过程、主要的计算支撑信息以及所使用的计算脚本。

Background: The study aimed to determine the apparent total tract digestibility coefficients(ATTDC) of nutrients, the apparent metabolizable energy(AME and AMEn) and the amino acid(AA) apparent ileal digestibility coefficients(AIDC)of a partially defatted(BSFp) and a highly defatted(BSFh) black soldier fly larvae meal. The experimental diets were: a basal diet and two diets prepared by substituting 250 g/kg(w/w) of the basal diet with BSFp or BSFh, ***: Significant differences were found between BSFp and BSFh meals for ATTDC of the nutrients: BSFp resulted more digestible than BSFh, except for ATTDC of CP which did not differed between meals, while a statistical trend was observed for ATTDC of DM and EE. The AME and AMEn values were significantly(P except for glutamic acid, proline and serine that were more digestible in the BSFh meal(P excellent source of AME and digestible AA for broilers with a better efficient nutrient digestion. These considerations suggested the effective utilization of defatted BSF larvae meal in poultry feed formulation.

The rapid prototyping biomodels manufacturing is a recent technology with great importance in oral and maxillofacial surgery. It provides a better surgical planning, decrease of anesthesia time and great functional and esthetic results. The aim of this experimental study was to evaluate the accuracy of rapid prototyping biomodels built by three-dimensional printing (3DP) technique, since this is one of the least expensive methods available. Linear measurements of standardized bone defects and anatomic distances were compared using a digital caliper of high precision in nine dry mandibles (gold standard) and their respective biomodels. The Bland-Altman test was used for statistical analysis (5% level of significance). The results showed strong concordance between the dry mandibles and their respective biomodels, with discrepancies smaller than 2 mmin most cases (97.4%). We can conclude that the biomodels built by 3DP technique can be used for surgical planning in Dentistry.

Background: Retinol (RE) is deeply involved in skin processes, therefore it is widely formulated in cosmetics, primarily as an anti-aging ingredient. Despite its efficacy, the safety profile of RE is controversial. Objectives: Pretinol (PRE) complex was formulated with two RE precursors, β-Carotene and Niacinamide, in order to deliver retinol-like skin benefits with healthier characteristics, assuming that skin enzymes will enable safe RE supply on spot. Methods: The expression levels of hyaluronic acid, Tumor Necrosis Factor alpha (TNFα) and Interleukin 1 alpha (IL-1α), were measured using various skin models before and after exposure to PRE and RE. Full genome microarray was performed and the affected genes and pathways were analyzed. Results: Following fibroblasts exposure to PRE, the natural synthesis of hyaluronic acid is significantly elevated. Skin safety, demonstrated via cytokines expression on ex-vivo skin, results with TNFα and IL-1α elevation by RE application. In contrary PRE significantly reduces TNFα while IL-1α is not affected. These results establish skin safety advantage of PRE vs RE. Microarray results examined on skin equivalents reveal the involvement of PRE in inflammatory attenuation. Conclusions: Formulating RE precursors as a safe source for RE is partially supported. PRE presents a skin benefit in parallel to RE, while PRE characteristics are suggested to be safer to skin.

This paper is devoted to the study of the potentiality of the Fricke dosimeter for the characterization of the highly energetic (62.1 MeV) α particles beams generated by a new cyclotron facility, namely ARRONAX started in 2009. Such for this high energetic α beam, in situ dosimetry is performed in order to avoid radiation safety inconvenience and to earn run time of irradiation. Therefore, an in situ Fricke dosimetry protocol is developed and its reliability is checked by comparison with other experiments carried out by using the traditional method (ex situ Fricke dosimetry) within another cyclotron facility (CEMHTI) and by comparison with literature data. To author’s knowledge, it is the first time that Fricke dosimetry is performed during the α irradiation experiment. The results of these in situ dosimetry experiments show that the value of ferric ions radiolytic yield (G(Fe3+) = (11.7 ± 1.2) 10–7 mol?J–1) extrapolated from literature data can be used for this higher energy of α particles (Eα = 62.1 MeV).

The micropropation is an important biotechnological tool for obtaining and maintaining mother vine plants with high quality plant health. The objective was to evaluate the establishment and multiplication in vitro and ex vitro acclimatization of grape genotypes with potential for Southern Brazil. Vine nodal segments were cultured in five culture medium formulations without adding growth regulators. It was evaluated the number of leaves and roots, length of roots and shoots, replication rate, relative chlorophyll index, percentage of regenerated and rooted plants, dry biomass of shoot, root and total plants grown in vitro and after acclimatization. In vitro propagation of IAC 571-6 rootstock and cv. Poloskei Muskotaly through nodal segments provided high rates of regeneration and rooting. High survival rates were obtained in the acclimatization of IAC 571-6 and P?l?skei Muskotaly. Considering all the variables, the culture medium Roubelakis showed the best growth rates and development for shoots and roots, and in vitro multiplication rate for IAC 571-6 and Poloskei Muskotaly grape varieties.

Peritoneal metastases (PM) from colorectal cancer (CRC) are associated with poor survival. The extracellular matrix (ECM) plays a fundamental role in modulating the homing of CRC metastases to the peritoneum. The mechanisms underlying the interactions between metastatic cells and the ECM, however, remain poorly understood, and the number of in vitro models available for the study of the peritoneal metastatic process is limited. Here, we show that decellularized ECM of the peritoneal cavity allows the growth of organoids obtained from PM, favoring the development of three-dimensional (3D) nodules that maintain the characteristics of in vivo PM. Organoids preferentially grow on scaffolds obtained from neoplastic peritoneum, which are characterized by greater stiffness than normal scaffolds. A gene expression analysis of organoids grown on different substrates reflected faithfully the clinical and biological characteristics of the organoids. An impact of the ECM on the response to standard chemotherapy treatment for PM was also observed. The ex vivo 3D model, obtained by combining patient-derived decellularized ECM with organoids to mimic the metastatic niche, could be an innovative tool to develop new therapeutic strategies in a biologically relevant context to personalize treatments.

During the SARS-Cov-2 or COVID-19 clinical course pandemic of the coronavirus family, we observed symptoms of the respiratory tract, fever, cough, sore throat, and fatigue. The most common symptoms were loss of smell and taste and, when aggravated, it could develop into pneumonia and even death. We selected 40 former COVID-19 patients, who answered a questionnaire with questions about the symptoms and complications after they were cured and which symptoms remained or appeared after the total isolation quarantine for a specific time. Among the answers, the most cited was about “forgetting”. Another observation noted was the number of cases in children, which surprised us, considering that, at the beginning of the pandemic, the danger was more related to the elderly population and those with comorbidities.
