Investigation on the Properties of Phenolic-Resin-Based Functional Gradient Thermal Protection Composite Materials

Aerospace
Crosslinked phenolic resin was prepared using hexamethylenetetramine (HMTA) as a crosslinking agent in hydrochloric acid solution. The ablation-heat-resistant material was prepared by a pressure-assisted RTM (resin transfer molding) process with ...

Evidence‐Based Clinical Practice Guidelines for the Management of Pediatric Febrile Neutropenia: Resource‐Sensitive Recommendations for the Asian Continent

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Febrile neutropenia (FN) is a frequent and serious complication in children receiving cancer therapy. Standardizing FN management across Asia is challenging due to variable healthcare infrastructure, diagnostic capacity, and infection patterns; however, it could improve resource use and patient outcomes.

Renal Denervation by Ablation with Innovative Technique in Resistant Hypertension

Arquivos Brasileiros de Cardiologia, 2013
Hypertension is the cause of thousands of deaths annually1, and half of the patients treated present controlled blood pressure (BP)2. Resistant hypertension (RH)is defined when the BP remains above the recommended targets with the use of three antihypertensive drugs with synergistic actions at maximum doses recommended and tolerated, preferably one ...
