This study reports synthesizing hydroxyapatite and carbonate-substituted hydroxyapatite using ultrasound and microwave radiation as processing methods. The authors report that these physical factors produced calcium-deficient hydroxyapatite and B-type carbonated apatite and increased in vitro bioactivity compared…

This case report describes radiofrequency pulmonary vein isolation in a 67-year-old man with dextrocardia and situs inversus totalis. The procedure successfully isolated all pulmonary veins using 3D mapping with intracardiac echocardiography guidance. No procedural complications were reported, and the authors…

This in vitro study exposed human osteoarthritic and non-osteoarthritic chondrocyte pellets to a sinusoidal 15 Hz electromagnetic field at 5 mT or 8 mT for 7 days. Under 5 mT, osteoarthritic chondrocytes showed increased expression of cartilage-related genes (COL2A1 and ACAN) compared with controls, while…

This study develops a quantum-mechanical radical pair mechanism model to examine how an extremely-low-frequency electromagnetic field (ELF-EMF) might influence early chemical hepatocarcinogenesis in rats. The model evaluates singlet-state recombination and quantum yield under a low magnetic field effect, proposing…

This engineering study evaluates microwave radiation in a household microwave oven for rapid treatment of 1000 g of human feces across multiple power and time settings. It reports substantial volume reduction and high pathogen eradication at higher power settings, and improved moisture removal when using lower power…

This laboratory study investigated ring-opening polymerization of ε-caprolactone using organic-acid catalysts to produce poly-ε-caprolactone intended as a biodegradable drug carrier. The authors report that citric acid catalysis yielded substantially higher molecular weight polymer than other catalysts. They also…

This laboratory study examined how UV-C radiation, an electromagnetic field, microwave radiation, and ultrasound affected polyphenolic compounds in chokeberry. Using UPLC-PDA-MS/MS, the authors report that UV-C, microwaves, and ultrasound generally increased several polyphenolic groups, while the electromagnetic…

This review-style article discusses gerontechnologies—mobile applications on smartphones/tablets and remote monitoring systems—for outpatient symptom monitoring and self-care management in older adults with heart failure. It frames these tools as potentially cost-effective and accessible when designed for older…

This conference paper describes an automated method for ABO and Rh-D blood typing using images captured by low-cost mobile phones of a fabric strip rapid diagnostic test. The approach applies morphological image processing steps including noise reduction, range filtering, and empirically derived heuristics to…

This proof-of-concept cohort study evaluated cardiac magnetic resonance (CMR) radiofrequency tissue tagging to diagnose constrictive pericarditis and compared results with surgical findings and cardiac catheterization. In 16 patients who underwent pericardiectomy, CMR positivity agreed 100% with intraoperative…

This animal organ-preservation study compared 12-hour porcine heart preservation at -3°C using a device generating a variable magnetic field versus conventional 4°C preservation. The subzero variable-magnetic-field condition showed higher myocardial ATP, lower lactate, and less mitochondrial ultrastructural damage…

This qualitative report describes phase one of a treatment development study for adolescent suicide prevention, including development of a safety plan smartphone application. Clinicians, parents, and adolescents emphasized transition of care, specific treatment targets, and safety planning as important. All…

This cross-sectional study surveyed 883 HIV-infected patients on ART in Soweto, South Africa, to identify demographic correlates of using mobile phones as reminder tools. Older age, female gender, and lower education were associated with lower use of phones for clinic appointment reminders. Older age and lower income…

This study enrolled 70 patients with primary hyperthyroidism and 74 healthy volunteers and assessed carotid artery structure and function using ultrasound RF data parameters before and after 131I therapy. Hyperthyroid patients showed worse carotid IMT and stiffness-related measures than controls at baseline. After…

This paper describes development of a fully implantable biotelemetry system that wirelessly transmits cardiac biomechanical force data along with ECG. The system uses a microcontroller with a bidirectional RF transceiver and was tested in a porcine model. The authors report successful transmission and recording of…

This animal study exposed rats of different early-life ages to 950 MHz UHF electromagnetic radiation for 30 minutes per day (SAR 1.0–1.3 W/kg) across gestation and/or early postnatal periods. The authors report no evidence of oxidative stress by TBARS or protein carbonyls, but report changes in fatty acid…

This engineering/medical physics study used Monte Carlo simulations to examine how a uniform transverse magnetic field affects the dose distribution of a 30 MeV electron beam in a water phantom. The abstract reports substantial changes in depth-dose, including reduced range and a pronounced end-of-range dose peak…

This study evaluated a fractional radiofrequency microneedle system for treating facial atrophic acne scars in Asian subjects over 1-, 3-, and 6-month follow-up after three monthly sessions. Of 26 completers, the most common self-reported improvement category at 6 months was 26–50% improvement, and scar volume…

This retrospective study evaluated liver lesion conspicuity during real-time MR-guided radiofrequency applicator placement using spoiled GRE and balanced SSFP MRI sequences in a 1.5 T scanner. Lesion detectability categories and contrast-to-noise ratio (CNR) were compared for hepatocellular carcinoma and liver…
