In the present research, biodiesel production from olive oils with different initial free fatty acid concentrations (2.5, 5.0, and 10.0%) was evaluated. A two-stage acid-catalyzed esterification and alkaline-catalyzed transesterification (ACT) process using the microwave heating method was compared with the traditional heating method. Free fatty ac...

Percutaneous radiofrequency ablation (RFA) and microwave ablation (MWA) are well-validated interventions for hepatocellular carcinoma (HCC). The purpose of this study was to compare their safety and efficacy through a meta-analysis of randomized controlled trials (RCT). MEDLINE, Pubmed, and the Cochrane Library were queried up to September 2020 usi...

Conventional microalgal drying consumes huge time and contributes to 60-80% of downstream process costs. With the aim to develop an effective and rapid drying process, the present study evaluated the performance of microwave based drying (MWD) with a power range of 360-900 W and compared with the conventional oven drying (OD) at 40-100 °C. MWD was ...

Ultrasound (US) and Microwaves (MW) are effective methods for processes intensification. Their combined use in the same reactor can lead to remarkable results. Recently there has been a resurgence of interest in this field for new synthetic applications using reactors based upon existing technologies. We describe here a new type of apparatus in whi...

To evaluate the effect of intravenous iodinated contrast on estimated glomerular filtration rate (eGFR) when administered immediately after thermal ablation of clinically localized T1a (cT1a) renal cell carcinoma (RCC). This HIPAA-compliant, dual-center retrospective study was performed under a waiver of informed consent. Three hundred forty-two co...
Magnetic resonance is a branch of science that aims to detect spins via their absorption and emission of electromagnetic radiation. Two areas can be distinguished: nuclear magnetic resonance (NMR) which aims at detecting the spins of nuclei, and electron spin resonance (ESR) that concerns the detection of the spin of unpaired electrons. In this the...

BACKGROUND Hepatectomy is the first choice for treating neuroendocrine tumor liver metastases. However, most patients with neuroendocrine tumor liver metastases are not suitable for hepatectomy. Ablation combined with hepatectomy can be an alternative to liver resection. AIM To explore the clinical effect of microwave ablation combined with hepatec...
