introduction the lulak abad iron occurrence is located in the northwestern part of the central iran, 55 km west of zanjan. mineralization at the lulak abad area was originally identified by zamin gostar company (2007), during a geophysical exploration. the present paper provides an overview of the geological framework, the mineralization characteristics, and the results of a geochemical study o...

Patients with acute type B aortic dissection (ABAD) are often treated medically. However, ABAD is a potentially serious emergency if complicated by acute organ ischemia. The therapeutic strategy for ABAD with visceral malperfusion remains controversial. Because emergent surgery has a high mortality rate, emergent endovascular treatment can be performed instead. We report a case of endovascular ...

BACKGROUND Continuous glucose monitoring system (CGMS) accuracy is of critical importance both in delivering therapeutic value and as a component of a closed-loop system. This study aims at assessing the differences between accuracy assessments of CGMS at home and at the clinical research center (CRC). METHODS Twelve patients with type 1 diabetes used the Dexcom® SEVEN® PLUS (DexCom, Inc.) CG...

BACKGROUND This study is aimed at comparing the performance of three continuous glucose monitoring (CGM) systems following the Clinical and Laboratory Standards Institute's POCT05-A guideline, which provides recommendations for performance evaluation of CGM systems. METHODS A total of 12 subjects with type 1 diabetes were enrolled in this study. Each subject wore six CGM systems in parallel, ...

Patients with uncomplicated acute type B aortic dissection (ABAD) can generally be treated with conservative medical management. However, these patients may develop aortic enlargement during follow-up, with the risk of rupture. Several predictors have been studied in recent years to identify ABAD patients at high risk of aortic enlargement, who may benefit from early surgical or endovascular in...

Sir, Acute type B aortic dissection (ABAD) is a life-threatening vascular emergency with an incidence estimated at 5-30 per 1 million people per year.[1] Available evidence support endovascular and surgical treatment for ABAD complicated by shock or organ damage. In uncomplicated ABAD, benefits of endovascular treatment are not well established and the preferred management mandates close clinic...

In this paper, the Periodic Capacitated Arc Routing Problem (PCARP) is investigated. PCARP is an extension of the well-known CARP from a single period to a multi-period horizon. In PCARP, two objectives are to be minimized. One is the number of required vehicles (nv), and the other is the total cost (tc). Due to the multi-period nature, given the same graph or road network, PCARP can have a muc...

Alzheimer's disease (AD) is a conformational disease that is characterized by amyloid-β (Aβ) deposition in the brain. Aβ exerts its toxicity in part by receptor-mediated interactions that cause down-stream protein misfolding and aggregation, as well as mitochondrial dysfunction. Recent reports indicate that Aβ may also interact directly with intracellular proteins such as the mitochondrial enzy...

arghash – ghasem-abad area in ne iran is located in the rim of the sabzevar structural zone. tertiary outcrops include granite and quartz monzodiorite porphyry associated with dacite and andesite volcanic rocks. in the study area, quartz gabbro and quartz monzodiorite dykes intruded the older rocks. granite and volcanic rocks host au-sb-bearing quartz-calcite veins. mineralized veins are mainly...

Using a new dataset, this paper presents new evidence on inequality in Latin America for the 19th century and studies the effects of factor endowments and trade on inequality. Recent research has highlighted the link between the colonial origins of inequality and its persistence in Latin America. We find that inequality varied substantially throughout the century a...
