This conference paper reports an engineering approach to convert wireless microwave power into near-infrared light using a miniaturized, wirelessly powered laser. The device is described as millimeter-scale and capable of being powered through >1 cm of tissue. The abstract focuses on enabling in vivo activation of…

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 engineering study examines composite optical dipole nano-antennas made of alternating silica and gold layers. It reports that a 50% filling factor yields a 2.0× increase in electric-field enhancement compared with a pure-gold antenna. The abstract frames the work in terms of photonics applications rather than…

This feasibility study evaluated whether delayed-enhancement MRI (DE-MRI) using commercially available tools could visualize radiofrequency ablation lesions in Japanese patients with atrial fibrillation. Of 15 scans, 3 were uninterpretable due to low image quality, and lesions were visualized in 8 of the remaining 12…

This cross-sectional questionnaire study assessed how orthopaedic residents and consultants in Karachi used smartphones for clinical work and academics. Most respondents owned smartphones and reported using apps and internet/email, but fewer used them to share clinical data. The paper does not assess electromagnetic…

This case report describes a 24-year-old woman with a rare pleomorphic adenoma of the nasal septum. The tumor was identified on CT imaging, diagnosed by incisional biopsy, and removed endoscopically with histology confirming pleomorphic adenoma. The report focuses on clinical management rather than evaluating…

This engineering-focused paper reports the design principle and performance of a MALDI ion source ("MALDI-2") combining rarefied supersonic gas jets with weak electric fields and injection into gas-filled RF multipoles. The abstract reports rapid collisional cooling (

This paper describes the design and preliminary implementation of a mobile-phone-based wireless blood pressure monitoring system that transmits data via Bluetooth and computes blood pressure and heart rate on the phone. The authors state that experiments demonstrated the device’s reliability and stability, and that…

This SCENIHR Opinion updates earlier 2009 SCENIHR documents on EMF health effects and research needs, focusing on new information and remaining knowledge gaps. The abstract primarily characterizes sources and patterns of exposure across static, ELF, IF, and RF fields in both public and occupational settings. It notes…

This engineering paper introduces an RFID sensor network concept integrating RFID with wireless sensor networks and emphasizes the role of antennas. It discusses coil, dipole, and microstrip antennas and reports designing a microstrip antenna for a wireless temperature monitoring and control system. Measurements are…

This conference paper describes development of new functions for an ICU/CCU remote monitoring system that uses a 3G mobile phone. The authors state that evaluations were performed on several different mobile phones and suggest the system has accuracy and real-time performance suitable for hospital adoption. The…

This engineering study evaluates whether passive 13.56-MHz RFID-based chemical sensors can quantify analytes reliably despite repositioning errors between the sensor and pickup coil. Using simultaneous measurement of multiple complex-impedance parameters and multivariate statistical analysis, the authors report…

This chemistry/engineering study reports the synthesis and NMR/MRI-relevant characterization of a trinuclear Gd(III) chelate intended for high-field MRI contrast applications. Using 17O NMR and proton relaxivity across multiple fields and temperatures, the authors infer bishydration, quantify water exchange and…

This item is a bibliography of reported biological phenomena and clinical manifestations attributed to radio-frequency and microwave radiation. It compiles over 2000 references published up to June 1971, with supplemental listings through Nov. 21, 1971, and gives particular attention to reported effects in humans.…
