RATIONALE Intraplaque hemorrhage (IPH) drives atherosclerosis through the dual metabolic stresses of cholesterol-enriched erythrocyte membranes and pro-oxidant heme/iron. When clearing tissue hemorrhage, macrophages are typically seen storing either iron or lipid. We have recently defined hemorrhage-associated macrophages (HA-mac) as a plaque macrophage population that responds adaptively to IP...

اندازه‌گیری پرتو گاما در زمینه‌های مختلف تحقیقاتی نیازمند آشکارسازهای کارآمد است. زمینه دزیمتری فوتون آشکارساز جرقه‌ای NaI(Tl) به عنوان یکی از سوسوزن معدنی (غیرآلی)، علت دارا بودن مقدار بالای نور خروجی بسیار حایز اهمیت این پژوهش سعی گردیده است، با کمک کد مونت‌کارلو (MCNPX) مقدمات مشخصه‌یابی توسط و بهره‌گیری روش‌های متفاوت محاسبه دز (تالی‌های 6F، 4*F، 6+F 8*F) انجام شود. طور معمول، یک تابش (شمار...

Impaired glucose tolerance (IGT) and type 2 diabetes including undiagnosed isolated postchallenge hyperglycemia (IPH) are common in the elderly. The aim of this study was to investigate the insulin secretion and sensitivity in Korean elderly lean diabetic women. Forty-one lean women aged 65-88 years took 2 hr oral glucose tolerance test (OGTT) and were stratified according to the WHO criteria (...

We report a very, rare case of idiopathic pulmonary haemosiderosis (IPH) occurring in a 68 yr old patient. Following alveolar haemorrhage onset, the diagnosis was obtained by a process of elimination, after clinical, endoscopic, cytohistological and laboratory investigations. The immunoglobulin G directed against myeloperoxidase antigen (C-ANCA), which was detected, can be regarded as indicativ...

Increasing evidence suggests that atherosclerotic plaque composition rather than size is linked to ischemic cardiovascular events, yet largescale population-based data in asymptomatic individuals remain scarce. This study sought investigate carotid relation incident stroke and coronary heart disease (CHD) a setting. Between 2007 2012, 1,349 persons (mean age 72 years, 49.5% women) from the Rott...

Human detection is the task of locating all instances human beings present in an image, which has a wide range applications across various fields, including search and rescue, surveillance, autonomous driving. The rapid advancement computer vision deep learning technologies brought significant improvements detection. However, for more advanced like healthcare, human–computer interaction, scene ...

O Novo Código Florestal (NCF), Lei Federal 12.651/2012, alterou as definições para Áreas de Proteção Permanente (APP) localizadas nos topos morro, o que reduziu drasticamente a área legalmente amparada tal categoria proteção. Nesse sentido, buscou-se compreender como uso e cobertura do solo podem alterar regime hidrológico, utilizando-se cenários simulações um modelo conceitual distribuído. Par...

BACKGROUND Intracranial bleeding (IB) is a common and serious consequence of traumatic brain injury (TBI). IB can be classified according to the location into: epidural haemorrhage (EDH) subdural haemorrhage (SDH) intraparenchymal haemorrhage (IPH) and subarachnoid haemorrhage (SAH). Studies involving repeated CT scanning of TBI patients have found that IB can develop or expand in the 48 hours ...

We present a new approach to the concrete planning (CP) shown to be a NP-hard problem [7]. This is the third stage of Web service composition (WSC) in the PlanICS framework [1]. The first two phases, namely an abstract planning and offer collecting, basing on an ontology, a user query, and a service registry provide data necessary for CP. A new hybrid algorithm (HSA), which combines Simulated A...

Portopulmonary hypertension (POPH) is a form of pulmonary arterial hypertension (PAH) in the setting of portal hypertension, and is associated with a poor prognosis [1]. The underling etiological cause of POPH is poorly understood [1]. Previously we have reported T cell-mediated immune deficiency or compromise in patients with chronic thromboembol-ic pulmonary hypertension (CTEPH), idiopathic p...
