PURPOSE: Conventional imaging cannot definitively detect nodal metastases from prostate cancer (PCa). We histologically validated 11-carbon-Acetate (11 C-Acetate) PET/CT for identifying nodal metastases, examining PCa factors that influence detection rates. MATERIALS AND METHODS: Patients with 11 C-Acetate-avid PET/CT imaged pelvic/retroperitoneal lymph nodes underwent high-extended robotic lymphadenectomy. A standardized mapping-template, comprising 8 pre-determined anatomic regions, was dissected during lymphadenectomy, allowing matched, region-based analysis and comparison of imaging and histological data...

Ghrelin, a peptide hormone produced in the gastrointestinal tract, has recently been found to be associated with the onset of myocardial fibrosis (MF). The exact mechanism, however, remains elusive. This study sought to identify the function and mechanism of ghrelin on MF after acute myocardial infarction (AMI). AMI was established in Spraque-Dawley rats by ligation of the left anterior descending (LAD). Ghrelin or saline was intraperitoneally injected two times per day for 8 weeks after ligation. The weight of heart (mg) and the weight ratio of heart to body (mg/g) as well as the fibrotic area was increased, while serum level of ghrelin was decreased after AMI...

Timely diagnosis of coronary involvement is paramount in Kawasaki disease (KD) as it can be associated with long-term morbidity. However, echocardiographic measurements of coronary artery dilation in KD are inconsistent and not proficient for all abnormal arteries. The purpose of this study was to investigate more valuable indices and determine their sensitivity and specificity for early diagnosis of coronary involvement in KD. We performed this retrospective study in 218 children. All patients underwent laboratory and echocardiographic evaluations upon admission...

REVIEW
D Allan Butterfield, Debra Boyd-Kimball
Alzheimer disease (AD) is a progressive neurodegenerative disorder associated with aging and characterized pathologically by the presence of senile plaques, neurofibrillary tangles, and neurite and synapse loss. Amyloid beta-peptide (1-42) [Aβ(1-42)], a major component of senile plaques, is neurotoxic and induces oxidative stress in vitro and in vivo. Redox proteomics has been used to identify proteins oxidatively modified by Aβ(1-42) in vitro and in vivo. In this review, we discuss these proteins in the context of those identified to be oxidatively modified in animal models of AD, and human studies including Familial AD (FAD), Preclinical AD (PCAD), Mild Cognitive Impairment (MCI), Early AD (EAD), Late AD (LAD), Down syndrome (DS) and DS with AD (DS/AD)...

BACKGROUND: A wider angle between the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) has been suggested to induce plaque formation in the arterial system via changes in shear stress. However, the relationship between the left main coronary artery (LM)-LAD angle and LAD stenosis has not been investigated. Therefore, we aimed to evaluate the associations between the LM-LAD and LAD-LCX angles and LAD stenosis. METHODS: Coronary computed tomography angiographies (CTAs) of 201 patients with suspected coronary artery disease were analyzed...

Background: An accurate diagnostic assessment of coronary artery disease is crucial for patients undergoing coronary artery bypass grafting (CABG). Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) to guide complete revascularization have not been adequately studied in patients prior to CABG. We compared an anatomic to a physiologic assessment of moderate coronary lesions (40-70% stenosis) in patients referred for CABG. Methods: We retrospectively reviewed 109 medical records of patients who underwent CABG at Tulane Medical Center from 2014 to 2016...

The Australian Sheep-Goat Scale (ASGS) is a commonly used measure of belief in the paranormal. The scale contains items that index extrasensory perception (ESP), psychokinesis (PK), and life after death (LAD). Although, research employs the ASGS as both a general (unidimensional) and factorial (multidimensional) measure, few studies have examined the appropriateness of these solutions. Accordingly, the present paper tested the psychometric integrity of the ASGS via two studies. Study 1 assessed ASGS factorial structure using confirmatory factor analysis...

This study examines the extent to which belief in extrasensory perception (ESP), psychokinesis (PK) or life after death (LAD), plus need for cognition (NFC) and faith in intuition (FI), predict the generation of confirmatory conjunction errors. An opportunity sample (n = 261) completed sixteen conjunction problems manipulated across a 2 event type (paranormal vs. non-paranormal) × 2 outcome type (confirmatory vs. disconfirmatory) within subjects design. Three Generalised Linear Mixed Models - one per paranormal belief type - were performed...

ETHNOPHARMACOLOGICAL RELEVANCE: Dragon's Blood (DB), the red resin of Dracaena cochinchinensis (Lour.) S. C., has been used in traditional Chinese medicine to treat acute myocardial infarction (AMI) for centuries. Evidence indicated that DB may exert cardio-protective effect by inhibiting inflammatory response during myocardial infarction. However, its pharmaceutical mechanism is still to be elucidated. AIM OF THE STUDY: Due to its potential anti-inflammatory effect, Dragon's Blood extract (DBE) was applied on AMI mice model in this study and its mechanism on inflammation via PI3K-AKT-mTOR signaling pathway was to be validated...

AIM: Recurrent thrombotic events still occur despite dual antiplatelet therapy in patient's post percutaneous coronary intervention (PCI) could be attributed to high on-treatment platelet reactivity. METHODS: A 44-year-old male, who had staged PCI to left anterior descending (LAD) 2 weeks after an anterior MI, with a drug-coated stent was readmitted with new anterior STEMI 35 days later. Coronary angiogram revealed mid-stent thrombus in situ. He had further uncomplicated PCI...

Spontaneous coronary artery dissection (SCAD) is one of the rarest causes of acute coronary syndromes, which include myocardial infarction (MI), stable and unstable angina, cardiogenic shock, and sudden death. The course of the disease, its etiology, prevalence, prognosis, and treatment remain ill-defined. Adding to the complexity is the fact that patients may lack typical risk factors for coronary heart disease. Herein, we report a case of a 42-year-old woman with vitamin B12 deficiency, who presented with chest pain; electrocardiography (ECG) findings were consistent with the acute anterior wall MI...

Approximately 40% of the patients with aortic aneurysm have coronary artery disease(CAD), which is an important factor contributing to early mortality associated with aneurysm surgery. Combined coronary artery bypass grafting (CABG)and aortic aneurysm repair of the ascending aorta to the aortic arch is often performed through a median sternotomy due to a good surgical exposure. However, treatment strategy of thoraco-abdominal aortic aneurysm(TAAA) combined with CAD is often controversial. We report a successful case of a 69-year-old man who underwent TAAA repair and CABG through a left thoracotomy...

Ventricular septal rupture(VSR) after acute myocardial infarction(AMI) is a rare and serious complication that is associated with extremely high mortality. Delayed VSR is particularly uncommon and is difficult to diagnose and treat. A 68-year-old man presented with dyspnea on effort. Coronary angiography revealed subtotal occlusion of the right coronary artery(RCA) with collateral circulation to the chronically and totally occluded left anterior descending artery (LAD). Elective stenting of the RCA was successfully performed for a recent MI of the RCA, while percutaneous coronary intervention(PCI) in the LAD ended in failure...

BACKGROUND: Henoch-Schonlein Purpura (HSP) is one of the most common vasculitides of childhood, with 10-20 cases per 100,000 children. It frequently occurs following an infectious trigger and involves IgA and C3 deposition in small vessel walls. HSP is characterized by palpable purpura plus IgA deposition on biopsy, arthritis/arthralgia, renal involvement (hematuria and/or proteinuria), and/or abdominal pain. It is not generally recognized as a cause of dilated coronary arteries. CASE PRESENTATION: We describe the first reported case of HSP presenting with dilated coronary arteries...

OBJECTIVE: To explore the role of microRNA-326 in myocardial fibrosis after myocardial infarction (MI) and its underlying mechanism. MATERIALS AND METHODS: MI rat model was constructed via left anterior descending artery (LAD) ligation. Infarct tissues, infarct border zone tissues and remote zone tissues were harvested at postoperative 1st, 2nd, and 4th week, respectively. The mRNA levels of microRNA-325, collagen I, fibronectin, and transforming growth factor-β1 (TGF-β1) in the above tissues were detected by qRT-PCR (quantitative Real-time polymerase chain reaction)...

BACKGROUND: Criteria for electrocardiographic detection of acute myocardial ischemia recommended by the Consensus Document of ESC/ACCF/AHA/WHF consist of two parts: The ST elevation myocardial infarction (STEMI) criteria based on ST elevation (ST↑) in 10 pairs of contiguous leads and the other on ST depression (ST↓) in the same 10 contiguous pairs. Our aim was to assess sensitivity (SE) and specificity (SP) of these criteria-and to seek their possible improvements-in three databases of 12‑lead ECGs...
