Introduction: Type 2 diabetes mellitus (T2D) is a chronic disease, primarily caused by a combination of defective insulin secretion and the inability of insulin-sensitive tissues to respond to insulin. Laparoscopic sleeve gastrectomy associated with duodenal ileal interposition (SGDII) has been shown to be a feasible treatment option for patients with T2D, as it provides improvement and control of glycemia, dyslipidemia and arterial hypertension. The aim of this study was to evaluate the mid and long-term results of SGDII for the treatment of diabetic patients, considering diabetic remission, weight loss and postoperative complications. Materials and Methods: Retrospective study with 96 patients with T2D submitted to SGDII, between 2010 and 2016. The glycated hemoglobin (HbA1c) value Results: Sixty-one patients (62.8%) were male, and 36 patients (37.2%) were female. The average age was 50.9 years. Median BMI was 33.43 kg/m2. The incidence of major postoperative complications in the first 30 days was 2.1%, with no mortality. Dyslipidemia control was sustained, after five years, in 62% of the patients. The five years follow-up demonstrated that 80% of patients had T2D remission at one year, 74.5% at three years and 61.8% at five years. Univariate analysis demonstrated that preoperative values of HbA1c and BMI, preoperative use of insulin, gender, and 30-day complication were not predictors of remission at all study intervals. The average duration of the disease was nine years and the mean glycated hemoglobin before surgery was 8.95%. Conclusion: SGDII resulted in good glycemic control at 5-years follow-up and represents a valid alternative for the treatment of T2D.

本研究基于当代中国人群3D牙齿模型数据,参照拉美人群进化和多样性研究联合会(consortium for the analysis of the diversity and evolution of Latin America,CANDELA)所使用的牙齿特征点标记方法,使用牙齿特征点间的欧几里得线性距离(Euclidean linear distances,ELD)表示的牙齿表型作为牙齿可观测特征的度量,探究个体因素(年龄、性别)和群体因素(民族)对当代中国人群牙齿可观测特征多样性的影响。通过对牙齿标记特征点的典型变量分析(canonical variate analysis,CVA)、交叉验证(cross validation,CV)、主成分分析(principal component analysis,PCA)以及对牙齿表型的Pearson相关性分析和差异分析,本研究发现进化上相近的群体牙齿可观测特征往往更接近。具体来说,汉族的上颌牙齿可观测特征和壮族、苗族较为接近而不同于蒙古族的,而藏族的上、下颌牙齿可观测特征不同于维吾尔族的;南北中汉族牙齿表型的差异具有明确的方向性,下颌牙齿差异比上颌更明显;从性别角度看,男女牙齿表型差异主要体现在尖牙上,男性尖牙平均宽度和高度显著大于女性的;对不同年龄群体的差异分析表明,遗传外因素对牙齿可观测特征的影响主要体现在尖牙、上颌第一磨牙、下颌第一前磨牙上。

泰格·伍兹对Scotty Cameron推杆的钟爱,使该品牌的球杆成了艺术品,甚至成为一种真正的资产类别。它们真的值得人们如此喜爱吗?很少有运动器材比推杆更加个性化的了。它被用来完成体育运动中一个比较精细的任务:让球缓慢滚动3英尺、10英尺或20英尺。除非遇到特殊情况,否则它会是高尔夫球手在每个球洞都会使用的唯一球杆。推杆功能的微妙之处掩盖了人们与这根球杆之间强大的情感联结。它不像鞋子那样在几周或几个月后会磨损、撕裂和更换。

Sensors Applied to Plant Breeding: Leaf Reflectance Indices (LRIs) and Resistance to Anthracnose in Capsicum annuum L. var. annuum

Advances in Remote Sensing 2024年第1期13卷 1-17页

作者： Rosimara Barboza Bispo Maria Do Socorro Bezerra Araújo Antônio andré da Silva Alencar Cláudia Pombo Sudré Rosana Rodrigues Plant Breeding Laboratory Darcy Ribeiro North Fluminense State University Campos dos Goytacazes Brazil Plant Breeding Laboratory University of the State of Mato Grosso Cáceres Brazil

The present work investigated the efficiency of leaf reflectance indices in the identification of Capsicum annuum L. var. annuum resistant to anthracnose in the fruit. Twenty-five F5:6 families originating from contrasting parents were assessed;the parents were accession UENF 2285 (susceptible to anthracnose) and accession UENF 1381, a hot pepper resistant to anthracnose in the fruit. The experiment was carried out in an experimental field in Campos dos Goytacazes, Rio de Janeiro, Brazil, between May and October of 2021. The treatments were arranged in a randomized block design, with three replications and five plants per plot. Fifteen LRIs were estimated using a CI-710 portable mini leaf spectrometer. The assessments covered all plant growth after flowering, and a total of six assessments were performed at 15-days intervals, beginning at 35 and ending 120 days after flowering (DAFs). Analysis of variance in a split-plot scheme was performed, as were tests of mean groupings and principal components analysis (PCA). The best period for evaluating leaf reflectance indices in C. annuum var. annuum is 120 days after flowering. The leaf reflectance indices PRI, CNDVI and Ctr2 stood out as effective in distinguishing between resistant and susceptible genotypes.

Structural Controls and Predictive Mapping of Tin, Niobium and Tantalum Mineralization Associated with the Mayo Darlé Stanniferous Granitoids;Contributions of Geostatistics

引用

Journal of Geoscience and Environment Protection 2024年第1期12卷 180-210页

作者： Bah-Yero liman Ngounouno Ismaïla Mbowou Gbambié Isaac Bertrand Alpha Baster Kenfack Fokem andré William Boroh Amadou Diguim Kepnamou Department of Earth Sciences Faculty of Science University of Ngaoundéré Ngaoundéré Cameroon Department of Mining Geology School of Geology and Mining and Engineering University of Ngaoundéré Meiganga Cameroon Department of Earth Sciences Faculty of Science University of Garoua Garoua Cameroon

The aim of this study of the spatial dispersion of tin, niobium and tantalum mineralization associated with the Mayo Darlé granitoids was to produce prospecting guides through predictive maps of Sn, Nb and Ta in the region. It was based on a database (in appendix) obtained after analysis of rock samples (greisens and quartz veins) collected in the field, using a portable X-ray fluorescence (XRF) spectrometer. Two approaches were used: 1) structural studies in the field using the directions of veins and fractures 2) the use of variographic maps, an essential element in geostatistics for determining directional anisotropies. A joint synthesis of the modelling results shows that tin, tantalum and niobium mineralization at Mayo Darlé is concentrated along strike intervals N315E to N320E, with mineralization also occurring along strike N35E for high-grade Sn, medium-grade Ta and low-grade Nb. In short, mineral concentrations disperse progressively in space: positively from east to west for tantalum and niobium, and inversely for tin.

This study was focused to assess major and trace elements in bauxitic duricrusts from Ngaoundal and its surroundings in order to establish their mining interest. To this end, fieldworks, mineralogical and geochemical analyses were carried out. Four facies of duricrust were identified and characterized from the summit to the top of the slope of the Ngaoundal mountain: scoriaceous, pisolitic, nodular and massive. Mineralogical and geochemical analyses performed on 16 samples, revealed a significant concentration of Al2O3 mainly in the scoriaceous facies (over 45% in grade), moderate in Fe2O3 (averaging 23.69%) and SiO2 (averaging 21.7%). Trace elements were generally low, excluding Cr (421 ppm on average), Zr (327 ppm on average and V (213 ppm on average). In addition, the limited quantities of alkalis (Na2O, K2O) and alkaline earths metals (MgO, CaO) coupled with the very high values of Chemical Index of Alteration (CIA) and Mineralogical Index of Alteration (MIA), (more than 99%) attest to the intense weathering of the studied materials. Allitization and monosiallitization constituted the crystallochemical phenomena that have led to the development of bauxitic minerals. More than 90% of gibbsite in scoriaceous facies, 52.21% - 76.01% of kaolinite in pisolitic facies and more than 40% of hematite in nodular facies were quantified. The relationships between the constitutive components indicated their interdependency during the bauxitization phenomenon. The mineralogical and geochemical properties highlighted the mining interest of the studied duricrusts to be valorized.
