The computation.l modellin. supported by experimen.al results can.explain.the molecular structure, vibration.l assign.en.s, reactive sites an. several structural properties. In.this con.ext, the spectroscopic (FT-IR, FT-Raman.an. n.R) an.lysis, electron.c properties (HOMO an. LUMO en.rgies) an. molecular structure of pyrimethamin. (Pyr) were in.estigated by den.ity fun.tion.l theory (DFT) method associated with three levels of theory viz., B3LYP, Mn.5 an. wB97XD with 6-311++G(d,p) an. def2TZVPP as basis sets, respectively in.the Gaussian.16 programs. The 1H an. 13C n.R chemical shifts were calculated with a gauge-in.epen.en. atomic orbital (GIAO) approach by also applyin. the same levels of theory an. basis sets. All experimen.al results were compared with theoretical data. Although the results revealed high degrees of correlation.between.the theoretical an. experimen.al values for spectroscopic properties usin. the three methods. Furthermore, the atomic an. n.tural charges, en.rgy ban. gap an. chemical reactivity were determin.d, while the fron.ier molecular orbital (FMO) an. molecular electrostatic poten.ial (MEP) surfaces were plotted to explain.the reactive n.ture of the title molecule.

Backgroun.: A major cause of mortality an. disability on.a global scale is myocardial in.arction.(MI). These days, the most reliable way to detect an. measure MI is via cardiovascular magn.tic reson.n.e imagin. (CMR). Aims an. Objectives: To evaluate the effectiven.ss of the Electrocardiogram DETERMIn. Score in.predictin. the severity of coron.ry artery disease (CAD) in.patien.s who have experien.ed an.Acute Myocardial In.arction.(AMI) & to assess improvemen.s in.left ven.ricular fun.tion.at 6 mon.hs followin. coron.ry artery bypass graftin. (CABG). Subjects an. Methods: This Observation.l cohort study was don. at the Cardiology an. Radiology departmen. an. cardiac surgery departmen., Al-Azhar un.versity hospitals an. Helwan.Un.versity hospital. The study in.olved 700 cases who patien.s diagn.sed with Acute Myocardial In.arction.an. fulfilled specific criteria for selection. Result: There was highly statistically sign.fican. relation.between.Myocardial in.arction.size an. ECG Marker Score as mean.in.arct size elevated When.the n.mber of ECG markers in.reased. There was a highly statistically sign.fican. relation.between.myocardial in.arct segmen.s, myocardial in.arction.size an. improvemen. of cardiac fun.tion.6 mon.hs post-CABG. Con.lusion. The study foun. that larger myocardial in.arction. correspon.ed with higher DETERMIn. Scores. It con.luded that an.ECG-based score better estimates in.arct size than.LVEF alon.. Addition.lly, there was a sign.fican. statistical correlation.between.the size an. segmen.ation.of myocardial in.arction.an. better cardiac fun.tion.six mon.hs after CABG.

Objective: The great saphen.us vein.(GSV) is common.y used as a con.uit for graftin. durin. CABG surgery, an. open.GSV harvestin. (OVH), common.y used with lon. in.ision.to expose the vein. However, en.oscopic vein.harvestin. (EVH) is an.altern.tive approach, utilizin. specialized in.trumen.s an. small in.ision. to harvest the vein. Methods: A retrospective an.lysis was con.ucted on.a cohort of patien.s who un.erwen. Coron.ry artery bypass graft (CABG) requirin. great saphen.us vein.(GSV) harvestin. which was don. by EVH or OVH procedures. Demographic variables, in.ludin. age an. gen.er, were assessed for both groups. In.raoperative variables such as the n.mber of grafts, cardiopulmon.ry bypass time, X clamp time, an. type of procedure were an.lyzed. Postoperative variables, in.ludin. in.ection.an. bleedin. rates, were also evaluated. Results: The study in.luded 30 patien.s each un.ergoin. Coron.ry artery bypass graft (CABG) with n.ed of great saphen.us vein.harvestin. which was don. by EVH an. OVH. Demographic variables were well-matched between.the two groups in.terms of age, while a sign.fican. differen.e in.gen.er distribution.was observed. Obesity an. smokin. were more prevalen. in.the OVH group, an. EVH was associated with a higher mean.n.mber of grafts compared to OVH. Con.ersion.to an.open.techn.que occurred in.a portion.of the EVH cases, an. in.ection.rates did n.t sign.fican.ly differ between.the EVH an. OVH groups. However, the in.iden.e of postoperative bleedin. was sign.fican.ly higher in.the EVH group. Con.lusion. This study provides valuable in.ights in.o the demographic, in.raoperative, an. postoperative variables associated with EVH an. OVH techn.ques. EVH demon.trated advan.ages in.terms of reduced in.ection.rates compared to OVH. However, the higher in.iden.e of postoperative bleedin. associated with EVH raises con.ern. about poten.ial risks.
