Rare Congenital Dissecting Thoracic Aortic Aneurysm in a Child with Noonan Syndrome: A Case Report.

We present a rare case of congenital thoracic aortic aneurysm (TAA) complicated with dissection in a nine-year-old girl with Noonan syndrome and atrial septal defect. She presented with rapid breathing and upper respiratory tract symptoms. Chest X-ray revealed a huge upper mediastinum with cardiomegaly.

LEP G2548A polymorphism is associated with increased serum leptin and insulin resistance among T2DM Malaysian patients.

Background: Type 2 diabetes mellitus (T2DM) is a chronic metabolic syndrome that is rapidly increasing across the world, especially in Malaysia. Leptin plays a vital role in the regulation of metabolism through its effect on peripheral tissues. G2548A polymorphism in the LEP gene promoter has been associated with insulin resistance, leptin, and type 2 diabetes mellitus across different population, but has not been inclusively reported within the Malaysian population.

Naphthalocyanine-Based NIR Organic Photodiode: Understanding the Role of Different Types of Fullerenes.

In this work, we presented experimental observation on solution-processed bulk heterojunction organic photodiode using vanadyl 2,11,20,29-tetra tert-butyl 2,3 naphthalocyanine (VTTBNc) as a p-type material. VTTBNc is blended with two different acceptors, which are PCBM and PCBM, to offer further understanding in evaluating the performance in organic photodiode (OPD). The blend film of VTTBNc:PCBM with a volumetric ratio of 1:1 exhibits optimized performance in the VTTBNc blend structure with 2.

Sensitivity Comparison of Refractive Index Transducer Optical Fiber Based on Surface Plasmon Resonance Using Ag, Cu, and Bimetallic Ag-Cu Layer.

A single-mode optical fiber sensor uses surface plasmon resonance (SPR) with a bimetallic silver-copper (Ag-Cu) coating compared to a single layer of Ag and Cu itself. Bimetallic Ag-Cu sensors are constructed by simple fabrication on a side-polished optical fiber, followed by an electron beam evaporation of Ag and Cu films. For this investigation, the thickness of the single Ag layer was set to 30 nm and the single Cu layer was set to 30 nm; whereas for the bimetallic combined Ag-Cu layer the thickness of Ag was 7 nm and Cu 23 nm.

Effect of dietary status on plasma-fractionated metanephrines in healthy individuals measured by Elisa.

Pheochromocytoma is a rare tumor that typically originates in the adrenal glands, often causing the over-production of catecholamines. The aim of this study was to determine whether dietary status could affect the concentration of plasma-fractionated metanephrines. This study was conducted at the Chemical Pathology Laboratory, Royal Hospital, Oman.
