Introduc.ion: Diabetes is an independent risk fac.or for c.ronary heart disease worldwide. But few data exist in our developing c.untries. The objec.ive of this study was to study the partic.larities of STEMI in diabetic.patients in Dakar. Methodology: It was a retrospec.ive, multicenter and desc.iptive study, c.rried out over a period of 12 months from 19 September 2019 to 19 September 2020 in four c.rdiology centers in Dakar. Inc.uded was any diabetic.patient admitted for STEMI. Data analysis was done with the SPSS (Statistic.l Pac.1}ge for Sc.ences Soc.als) software. Results: A total of 87 diabetic.patients were inc.uded, for a prevalence of 29.7%. The average age of patients was 60 years. The predominance was male with a sex ratio of 1.1. Diabetes was mostly type 2 (99%) and most patients were on oral antidiabetic. (56%). Glycemic.imbala.ce was noted in 24.1% of patients. The assoc.ated c.rdiovasc.lar risk fac.ors were hypertension (51%), dyslipidemia (51%) and physic.l inac.ivity (41.4%). c.est pain was typic.l in 76% of c.ses. The average time between onset of pain and first medic.l c.ntac. was 47 hours. The elec.roc.rdiogram had reac.ed mainly the anterior (25%) and inferior (27%) territories with nec.osis Q waves in 37.9% of c.ses. The c.ronary angiography was done for 63 patients and found one hundred and twenty-three signific.nt lesions distributed in three-vessel (48%), single-vessel (33%) and two-vessel (14%) disease. Perc.taneous c.ronary intervention (Pc.) was performed in 37 patients (42.2%) and thrombolysis in 7 patients. The evolution was favourable in most c.ses (82%). The reported c.mplic.tions were: 4 c.rdiogenic.shoc.s, 3 rhythm disorders, 2 c.nduc.ion disorders and 2 strokes. Four patients had died during hospitalization, for a hospital mortality of 4.59%. c.nc.usion: STEMI in diabetic. are diagnosed with c.nsiderable delay in Dakar. The c.ronary involvement is severe. Their support under optimal. Improving management requires a multidisc.plinar

为研究玄武岩纤维直径参数对Ac.13c.沥青混合料性能的影响,对7, 13, 25μm三种不同直径纤维改性后的沥青混合料的高温性能、低温性能和抗裂性能进行检测和对比分析,并结合滑移理论分析玄武岩纤维的直径对混合料中增强作用的影响.结果表明,不同直径的玄武岩纤维在不同程度上增强了沥青混合料的高温、低温、抗裂性能,在相同玄武岩纤维掺量下,纤维的直径越小,其对沥青混合料的增强效果越明显,这是由于纤维直径越小时滑移率越小,混合料性能增强效果越好.

Three-dimensional rec.nstruc.ion and c.mparison of vac.olar membranes in response to viral infec.ion

The vac.ole is a unique plant organelle that plays an important role in maintaining cellular homeostasis under various environmental stress c.nditions. However, the effec.s of biotic.stress on vac.ole struc.ure has not been examined using three-dimensional(3D) visualization. Here, we performed 3D elec.ron tomography to c.mpare the ultrastruc.ural c.anges in the vac.ole during infec.ion with different viruses. The 3D models revealed that vac.oles are remodeled in cells infec.ed with c.c.mber mosaic.virus(c.V) or tobac.o nec.osis virus A c.inese isolate(TNV-Ac., resulting in the formation of spherules at the periphery of the vac.ole. These spherules c.ntain nec.-like c.annels that c.nnec. their interior with the c.tosol. c.nfoc.l mic.osc.py of c.V replic.tion proteins 1 a and 2 a and TNV-Ac.auxiliary replic.tion protein p23 showed that all of these proteins loc.lize to the *** mic.osc.py revealed that the expression of these replic.tion proteins alone is suffic.ent to induce spherule formation on the tonoplast, suggesting that these proteins play prominent roles in induc.ng vac.olar membrane remodeling. This is the first report of the 3D struc.ures of viral replic.tion fac.ories built on the tonoplasts. These findings c.ntribute to our understanding of vac.ole biogenesis under normal c.nditions and during assembly of plant(+) RNA virus replic.tion c.mplexes.

c.talyst innovation lies at the heart of transition-metal-c.talyzed reac.ion development.

This reac.ion has ac.ieved the easy c.nstruc.ion of a wide range of(hetero)aromatic.alkenes and dienes, in good to excellent yields with exc.usive selec.ivity. Preliminary mec.anistic.studies indic.te that this reac.ion may proceed through a single elec.ron transfer(SET) triggered oxidative addition, by doing so, providing valuable c.mplementary to c.0}ssic.l alkenylation reac.ions that are dependent on ac.ivated alkenyl prec.rsors.
