马来半岛广泛发育的晚古生代‒早中生代岩浆作用完整地记录了古特提斯洋俯冲‒碰撞‒消亡的演化历史。该洋盆于中‒晚三叠世关闭,随之发生陆‒陆碰撞、地壳增厚以及造山带垮塌,区域上形成大规模的碰撞后火成岩,构成了东南亚古特提斯巨型火成岩带东部和中部花岗岩省的重要组成部分,但关于其岩石成因及构造背景仍然存在不同认识。因此,本文对马来半岛东部晚三叠世花岗岩开展了详细的岩相学、年代学以及地球化学研究,并结合区域地质资料综合探讨了晚三叠世岩浆作用的演化规律及深部动力学过程。研究表明马来半岛东部晚三叠世花岗岩可以分成两组:第一组为231~222 Ma,样品显示出较为富集的同位素特征((^(87)Sr/^(86)Sr)i=0.72040~0.72518,εNd(t)=−10.4~−6.7,εHf(t)=−11.5~+0.1),来自变火成岩和变杂砂岩的混合源区;第二组样品形成于218~216 Ma,对应的(^(87)Sr/^(86)Sr)i=0.70576~0.71464,εNd(t)=−9.1~−3.9,εHf(t)=−3.9~+1.9,表明其源区存在一定新生地壳物质的参与,且Ga/Al、FeO^(T)/(FeO^(T)+MgO)值及锆石饱和温度相对较高,具有典型的A型花岗岩特征。年代学结果表明古特提斯东部和中部花岗岩省晚三叠世岩浆作用的峰期为220 Ma,且具有相似的元素‒同位素变化规律,证实古特提斯洋碰撞后造山垮塌主要发生于220 Ma,软流圈上涌促使中‒下地壳物质发生部分熔融从而形成了区域大规模的岩浆作用。

This study has isolated,characterized,and identified potential plant growthpromoting rhizobacteria(PGPR)with multiple PGP characteristics(N_(2)-fixation,P-and K-solubilization,IAA,and siderophores production)from the rhizosphere BRIS soil of Acacia mangium.A total of 24 pure colonies were isolated and only 8 colonies were selected for further evaluation of the growth rate in 5%organic molasses medium supplemented with 2%KNO_(3).Based on the biochemical,potential PGP characteristics and growth performance,3 superior PGPR strains were selected and identified as Paraburkholderia unamae(UA1),Bacillus amyloliquefaciens(UA6),and Enterobacter asburiae(UAA2)by partial sequencing of the 16S rRNA *** selected bacterial strains either in single or mixed(UA1+UA6+􀀁UAA2)cultures have shown a significant biochemical estimation of the PGP *** strain has its own PGPR traits superiority with UA1 showing the best PGP characteristic followed by UA6 and *** use of mixed bacterial strains was beneficial as it showed the best performance in N_(2)-fixation,siderophores production,and significant effect on corn phenology,growth and yield compared to using a single *** types of microbes showed potential to be used as biofertilizer and should be exploited more.

Introduction: Sickle cell disease, which is the most common hereditary hemoglobinopathy in the world, attacks all body systems, particularly the kidneys. The view of this study was to investigate the predictive factors of kidney damage during sickle cell disease. Materials and methods: It was a retrospective, descriptive and analytical study on files of sickle cell patients hospitalized in the Hematology-Oncology Department of Donka University Hospital during a period from January 1, 2016 to December 31, 2019. Records of sickle cell patients with one or more renal abnormalities were retained. Sickle cell patients without kidney damage were also selected for a comparative study. Only patients without sickle cell disease were excluded. Results: Seventy-five (75) medical records were collected during the study period. From these cases, thirteen (13) records with kidney disease were observed, a frequency of 17%. The mean age of patients was 24.2 years for extremes of 10 and 65 years. The sex ratio was 1.6 in favor of men. The SSFA2 form was the most represented with 92%. 24-hour proteinuria was measured in 13 patients between whom 6 patients (46.2%) had a proteinuria level ≤ 1 g. Eight (8) patients (61.5%) were in stage 1 of chronic kidney disease. The most common type of renal involvement was tubulo-interstitial nephropathy with 8 patients (61.5%). Bivariate analysis showed that elevated serum creatinine (P 2 form of the sickness (P Conclusion: After the observation of an increased serum creatinine and urea, a predominance observation of the SSFA2 form, it should be possible to target patients for whom screening for kidney damage should henceforth be systematic.
