2. 9p21 Locus Polymorphisms: Risk and Severity Factors of Coronary Artery Disease in Venezuelan Patients
Abstract Background: The 9p21 region is the most relevant locus associated with coronary heart disease in different populations. However, there are no studies that prove that this region is a risk factor in the Venezuelan population. Objectives: To analyze whether or not the 9p21 rs1333049 polymorphism is a risk factor for acute myocardial infarction (AMI)

3. The role of vein grafts in reconstructive head and neck microsurgery
Abstract Objective: Free tissue transfer is widely used for head and neck reconstruction. In certain circumstances, vein grafting is required to elongate free flap pedicles to connect them to appropriate recipient vessels. Because of controversy regarding the use of interposition vein grafts in free tissue reconstruction, this paper reports vein graft indic

4. Vascular Spectrum of Imaging Findings in COVID-19: Ischemic, Hemorrhagic, and Thromboembolic Complications
Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can

5. RhoA/ROCK-1 Signaling Pathway and Oxidative Stress in Coronary Artery Disease Patients
Abstract Introduction: Coronary artery disease (CAD) is an ischemic condition that occurs as a result of partial or complete interruption of blood flow by narrowing or complete blockage of the vessels supplying the heart, which are called coronary arteries. Our objective in this study is to investigate the RhoA/Rho-associated kinase (ROCK)-1 signaling pathw

6. Predictive factors of melanoma thickness
Abstract Background: Melanoma thickness is a relevant prognostic marker that is crucial for staging and its calculation relies on the histopathological examination. There is a risk of thickness underestimation with an incisional biopsy if the latter is not performed on a tumor area where the thickness is maximal. This occurrence may have an impact on a ther

8. A Morphometric Analysis of Pathological Alterations in Hemorrhoidal Disease Versus Normal Controls: A Controlled Trial
ABSTRACT Objective Until today, the true pathophysiology of hemorrhoidal disease (HD) has not yet been unraveled. More and more evidence guides us towards the hypothesis that reduced connective tissue stability is associated with a higher incidence of hemorrhoids. The present study aimed to compare the quantity and quality of collagen, and vessel morphometr

10. Quercetin as a nephroprotector after warm ischemia: histomorphometric evaluation in a rodent model
ABSTRACT Purpose: To quantitatively evaluate the possible long-term protective effects of quercetin during renal warm ischemia. Materials and Methods: Male rats were allocated into 4 groups: sham (S), sham quercetin (SQ), ischemia (I), and ischemia quercetin (IQ). Groups SQ and IQ received quercetin (50mg/kg) before and after surgery. Groups I and IQ had t

12. A laparoscopic vascular blocking forceps used for renal carcinoma combined with tumor thrombus
ABSTRACT Objectives: To discuss the feasibility and efficacy of a laparoscopic vessel blocking forceps in laparoscopic inferior vena cava (IVC) thrombectomy (1–3). Materials and methods: The patient was secured in a left lateral decubitus position. The surgical field was built with 4-trocar. The laparoscopic vessel blocking forceps was used to block the
