Publication Metadata only Hair removal with a combined light/heat based photoepilation system(2001-12-01) D. J. Goldberg; S. Silapunt; Skin Laser & Surgery Specialists of New York & New Jersey; Rutgers New Jersey Medical School; Mahidol UniversityBACKGROUND: A variety of lasers and light sources have been used for removal of unwanted hair. A novel, new, flashlampbased device, with a mechanism of action based on a combination of both emitted light and heat, has been developed for safe... and reliable hair removal. OBJECTIVE: To assess the efficacy and safety of hair removal by a combined light/heat based photoepilation system. METHODS: A pilot trial was undertaken. Twenty one anatomic sites received one to three treatments with the SpaPublication Metadata only Pulpal blood flow recorded from exposed dentine with a laser Doppler flow meter using red or infrared light(2018-03-01) Kanittha Kijsamanmith; Noppakun Vongsavan; Bruce Matthews; University of Bristol; Mahidol Universitythe pulp by cutting a buccal, class V cavity in the tooth; and after sectioning the coronal pulp transversely through the exposure. Results There was no significant change in mean blood flow recorded with either light source when the tooth was anaesthetized... flow was recorded alternately with infrared or red light from the exposed dentine under four conditions: before and after injecting local anaesthetic (3% Mepivacaine without vasoconstrictor) (LA) over the apex of the root of the tooth; after exposingPublication Metadata only Characterization of a potent and highly unusual minimally enhancing antibody directed against dengue virus(2018-11-01) Max Renner; Aleksandra Flanagan; Wanwisa Dejnirattisai; Chunya Puttikhunt; Watchara Kasinrerk; Piyada Supasa; Wiyada Wongwiwat; Kriangkrai Chawansuntati; Thaneeya Duangchinda; Alison Cowper; Claire M.

Dengue virus is a major pathogen, and severe infections can lead to life-threatening dengue hemorrhagic fever. Dengue virus exists as four serotypes, and dengue hemorrhagic fever is often associated with secondary heterologous infections. Antibody-dependent enhancement (ADE) may drive higher viral loads in these secondary infections and is purported to result from antibodies that recognize dengue virus but fail to fully neutralize it. Here we characterize two antibodies, 2C8 and 3H5, that bind to the envelope protein. Antibody 3H5 is highly unusual as it not only is potently neutralizing but also promotes little if any ADE, whereas antibody 2C8 has strong capacity to promote ADE. We show that 3H5 shows resilient binding in endosomal pH conditions and neutralizes at low occupancy. Immunocomplexes of 3H5 and dengue virus do not efficiently interact with Fcγ receptors, which we propose is due to the binding mode of 3H5 and constitutes the primary mechanism of how ADE is avoided.Publication Metadata only A comparison between red and infrared light for recording pulpal blood flow from human anterior teeth with a laser Doppler flow meter(2011-06-01) Kanittha Kijsamanmith; Siriporn Timpawat; Noppakun Vongsavan; Bruce Matthews; Mahidol University; University of Bristollaser Doppler flow meter (Periflux 4001) equipped with both red and infrared lasers.

This suggests that light microscopy may not detect low levels of spore shedding. Considering that the asymptomatic group are a potential source of infection...Stool samples from seven human immunodeficiency virus (HIV)-negative and two HIV-positive children with asymptomatic Enterocytozoon bieneusi infections were daily examined to quantify spore shedding using Gram-chromotrope staining under lightPublication Metadata only Reliable interpretation and long-term stability using sybrtm safe fluorescent assay for loop-mediated isothermal amplification (Lamp) detection of leishmania spp.(2019-01-01) T. Thita; J. Manomat; S. Leelayoova; M. Mungthin; T. Ruang-Areerate; Mahidol University; Phramongkutklao College of Medicine(MON-229) were compared under two different light sources, i.e., blue light and ultraviolet light transilluminators. Regarding the SYBR™-LAMP assay, the detection limit of DNA of both L. siamensis and L. martiniquensis was 103 parasites/mL. The assay... exhibited consistency and reproducibility without requiring any post-reaction preparations. The dye is generally available, affordable and safe while reliable interpretation can be easily visualized under both blue light and ultraviolet lightPublication Metadata only Edible insects in Thailand: An unconventional protein source?(1997-01-01) J. Yhoung-Aree; P. Puwastein; G. A. Attig; Mahidol Universitypopulation reside, sociocultural and economic limitations often obstruct the use of more common protein sources such as pork, beef, poultry, milk and eggs. Alternatively, edible insects are readily available and commonly eaten by rural people and can thus... serve as an important protein source. In Thailand, over 50 species of insects are edible and can be consumed throughout the year.
