Cardiovascular disease remains the leading cause of mortality and morbidity despite the identification of major risk factors and risk reduction strategies. Myocardial infarction (MI) is a relevant cardiovascular worldwide event for morbidity and mortality. In most cases, sudden cardiac death is triggered by ischemia-related ventricular tachyarrhythmia and accounts for 50% of deaths from cardiovascular disease in developed countries. This is a descriptive analytical case control study aimed to determine D-dimer, PT and PTT level and among patients with acute myocardial infarction conducted in Sudan cardiac center hospital. Thirty patients after MI and twenty normal controls have been studied. The MI patients also include co-exist disease diabetes and hypertension, they receive different anticoagulants therapy. The result demonstrates a significant increase post MI in the mean level of D-dimer (p = 0.00) whereas none significantly compares to control group. There are no differences between INR (0.393), PTT (0.648) and PT (0.393), parameters between cases and controls. In conclusion, our study reveals higher D-dimer level among patients than the control. In conclusion, serum D-dimer levels appear to be useful for diagnosing MI and may assist in the prediction of mortality among those patients which are presented with acute chest pain or known diagnosed with MI and should be done as indicator for thrombosis risk during therapy in post MI.

International Journal of Otolaryngology and Head & Neck Surgery 2024年第5期13卷 305-310页

作者： mohammed Atiah Alzahrani Yahia Dhafer Alahmari ali Jaber Asiry Ibrahem Hamad Erwe Ghada ahmed Bin Abbas Department of Otorhinolaryngology Aseer Central Hospital Abha Saudi Arabia College of Medicine University of King Khalid Abha Saudi Arabia

Glomus tumors are extremely rare tumors that arise from paraganglionic cells, which are derived from neural crest cells. These tumors are benign, slow-growing, locally invasive, and destructive. Glomus tumors are the most common tumor of the middle ear cavity and the second most common tumor of the temporal bone. We present a case of a 49-year-old healthy female who, following diagnostic tools, received surgical intervention resulting in an excellent outcome. Our case report includes a comprehensive analysis of published cases in the literature.

Ding w-Flat Modules and Dimensions

Algebra Colloquium 2018年第2期25卷 203-216页

The introduction of w-operation in the class of flat modules has been successful. Let R be a ring. An R-module M is called a w-fiat module if Tor1r（M, N） is GV-torsion for all R-modules N. In this paper, we introduce the w-operation in Gorenstein homological algebra. An R-module M is called Ding w-flat if there exists an exact sequence of projective R-modules ... → P1 → P0 → p0 → p1 → ... such that M Im（P0 → p0） and such that the functor HomR （-,F） leaves the sequence exact whenever F is w-flat. Several well- known classes of rings are characterized in terms of Ding w-flat modules. Some examples are given to show that Ding w-flat modules lie strictly between projective modules and Gorenstein projective modules. The Ding w-flat dimension （of modules and rings） and the existence of Ding w-flat precovers are also studied.
