Phosphorylation state of a Tob/BTG protein, FOG-3, regulates initiation and maintenance of the Caenorhabditis elegans sperm fate program
(2011-05-12)FOG-3, the single Caenorhabditis elegans Tob/BTG protein, directs germ cells to adopt the sperm fate at the expense of oogenesis. Importantly, FOG-3 activity must be maintained for the continued production of sperm that ... -
Photodynamic Therapeutic Effect of Nanostructured Metal Sulfide Photosensitizers for Cancer Treatment
(2022-03-08)Photodynamic therapy (PDT) utilizes photosensitizers (PSs) to produce reactive oxygen species (ROSs) upon irradiation, which causes the shutdown of vessels and deprives the tumor of nutrients and oxygen, and in turn induces ... -
Photofrin-Mediated Electroporation-Assisted Photodynamic Therapy of MCF-7 Human Breast Cancer and B16-F10 Mouse Melanoma Cells
(East Carolina University, 2011)Photodynamic therapy is a relatively new player on the field of cancer treatment that involves the injection of a nontoxic light-sensitive drug followed by light excitation, creating reactive oxygen species that cause ... -
Photoplethysmographic imaging and analysis of pulsatile pressure wave in palmar artery at 10 wavelengths
(2022-11-10)Significance As a noncontact method, imaging photoplethysmography (iPPG) may provide a powerful tool to measure pulsatile pressure wave (PPW) in superficial arteries and extract biomarkers for monitoring of artery wall ... -
Phylogenetics and Systematics of the Millipede genus Brachycybe Wood, 1864 (Platydesmida: Andrognathidae)
(East Carolina University, 2010)The genus Brachycybe Wood, 1864 (Platydesmida: Andrognathidae) belongs to an ancient millipede lineage that has persisted since the Miocene. The group displays a Holarctic distribution with species in the eastern Nearctic, ... -
Phylogenomic Reconstruction of the Neotropical Poison Frogs (Dendrobatidae) and Their Conservation
(2019-01-29)The evolutionary history of the Dendrobatidae, the charismatic Neotropical poison frog family, remains in flux, even after a half-century of intensive research. Understanding the evolutionary relationships between dendrobatid ... -
Phylogeny and Classification of the Trapdoor Spider Genus : An Integrative Approach to Evaluating Taxonomic Hypotheses
(2010)Background Revised by Bond and Platnick in 2007, the trapdoor spider genus Myrmekiaphila comprises 11 species. Species delimitation and placement within one of three species groups was based on modifications of the male ... -
Physical activity across the curriculum: year one process evaluation results
(East Carolina University, 2008-07-07)Background: Physical Activity Across the Curriculum (PAAC) is a 3-year elementary school-based intervention to determine if increased amounts of moderate intensity physical activity performed in the classroom will diminish ... -
PHYSICAL ACTIVITY AND GREENWAY USAGE AMONG PROXIMATE AND NON-PROXIMATE RESIDENTS
(East Carolina University, 2011)Regular physical activity can reduce the risk of obesity and can help people live longer, healthier lives. One mechanism to increase physical activity and reduce the risk of obesity is to facilitate active living. Greenways ... -
