This study describes the design, pilot testing, and validation of a mobile phone application version of the Guatemala NEMS-S supermarket survey. In a single supermarket, the app demonstrated high interrater reliability relative to the paper version and good test-retest reliability. The app also reduced survey…

This case report describes a 30-year-old male admitted with intermittent fresh blood expectoration for three days and later found to have a small bleeding site on the posterior surface of the left tonsil. The authors diagnosed spontaneous tonsillar hemorrhage. They report successful management using low-temperature…

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 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 study reports implementation of a passive RFID system to passively track patient flow in a radiation therapy clinic using readers/antennae in linac vault areas. Across 4302 treatment fractions from 144 patients, the system achieved about 70% read reliability and enabled comparison of median in-vault treatment…

This qualitative case study (2011) describes a pilot mobile phone-based management information system for neglected tropical disease control in Tanzania, where village health workers used phones with web-based software to capture data at source. The study reports improved routine work efficiency and increased…

This study tested noninvasive 13.56 MHz radiofrequency electric fields as a treatment adjunct for pancreatic ductal adenocarcinoma in cell lines and mouse xenograft models. The authors report RF exposure caused cytotoxicity in PDAC cells via autophagy (not apoptosis) and that normal pancreatic ductal epithelial cells…

This study examined how pulsed electric field, hot water dip, ethanol vapours, and UV irradiation affected antioxidant-related properties of mung bean sprouts during storage at room and low temperatures. Ethanol vapour-treated sprouts had the highest ascorbic acid, total phenols, and antioxidant activity. Polyphenol…

This paper reports routine EMOST (Electro-Magnetic-Own-Signal-Treatment) use with low-frequency, low-intensity electromagnetic fields in two children with chronic constipation and persistent diarrhea. The authors state these conditions were eliminated following treatment. The abstract briefly discusses possible…

This article describes a pilot mobile-phone-based support system (“celemedicine”) for mid-level rural health workers in Gulmi District, Nepal, enabling free calls to three general practitioner doctors at the district hospital. The intervention aims to improve appropriate referral and connectivity between peripheral…

This engineering paper models the driving system of a centrifugal blood pump for extracorporeal circulation, focusing on disc magnetic coupling. It uses a three-dimensional static magnetic field edge element method in Ansys to numerically calculate magnetic fields and analyze how coupling parameters relate to…

This paper describes a SAR measurement system for a 3G mobile phone (1718.5 MHz) using brain phantom material in a Perspex box sized to a small rat volume, with induced fields measured at multiple locations. SAR was computed from induced-field measurements and also estimated experimentally via temperature rise, with…

This engineering study describes using antenna-coupled microwave radiation to enhance laser-induced breakdown spectroscopy (LIBS) emission from a Gd2O3 sample at reduced pressure. The authors report substantially increased plasma emission intensity, higher-temperature plasma, and longer emission lifetime when…

This laboratory study examined Rayleigh-Bénard convection in liquid gallium under varying strengths of a uniform imposed horizontal magnetic field. Using ultrasonic velocity profiling and temperature monitoring, the authors mapped a regime diagram across Ra and Q and identified five flow regimes. The results describe…

This paper theoretically investigates magnetic-field-induced phenomena in bent-core nematic liquid crystals, focusing on how molecular biaxiality modifies the response. Using molecular field and Landau theory, it reproduces reported experimental trends such as an enhanced Cotton-Mouton effect and an increase in the…
