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 ...

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 ...

Kras oncogene ablation prevents resistance in advanced lung adenocarcinomas

Journal of Clinical Investigation, 2023
KRASG12C inhibitors have revolutionized the clinical management of patients with KRASG12C-mutant lung adenocarcinoma. However, patient exposure to these inhibitors leads to the rapid onset of resistance. In this study, we have used genetically engineered mice to compare the therapeutic efficacy and the emergence of tumor resistance between genetic ...

Wide temperature range protection performance of Zr–Ta–B–Si–C ceramic coating under cyclic oxidation and ablation environments

High Temperature Materials and Processes
In order to improve the oxidation and ablation resistance of carbon materials, Zr–Ta–Si–C–B coatings with different Zr/Ta ratios were successfully prepared on the graphite surface by combining slurry impregnation and reactive melt infiltration (RMI). The

Hospitalization Through Families’ Eyes: Comparing Inpatient Care Quality for Children With Sickle Cell Disease and Cystic Fibrosis in Canada

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
