Ultraviolet-C Powered Air Purifying Respirator (UVC PAPR)
… respirator (PAPR) incorporating direct ultraviolet-C (UVC) germicidal irradiation. The proposed PAPR aims to provide enhanced protection by actively sterilizing air through this UVC chamber immediately prior to inhalation. This approach offers an advantage over traditional filter-based …

Ultraviolet C Inactivation of <em>Salmonella enterica</em> in Raw Chicken Juice on Food Contact Surfaces with the Contamination Sanitization Inspection and Disinfection (CSI-D+) Device
<p><em>Salmonella</em> is the top bacterial cause of foodborne illness in the United States, with outbreaks commonly associated with poultry products. The Contamination Sanitization Inspection and Disinfection (CSI-D+) device is a handheld portable system equipped with fluorescence imaging with …

Later Life Consequences of Developmental Mitochondrial DNA Damage in C. elegans
… helix distorting lesions such as those caused by ultraviolet C (UVC) radiation and also many environmental toxicants, including benzo[a]pyrene (BaP) [8]. While these lesions cannot be repaired, they are slowly removed through a process that involves mitochondrial dynamics and autophagy [9, 10]. …

New Insights into the Roles of Human DNA Damage Checkpoint Protein ATR in the Regulation of Nucleotide Excision Repair and DNA Damage-Induced Cell Death
… are the major pathways by which cells handle ultraviolet C (UV-C)- or other exogenous genotoxin-induced bulky DNA damage. However, it is unclear how these 2 pathways may be coordinated. In this study we show that ATR physically interacts with NER factor xeroderma pigmentosum group A (XPA) …

Disinfection of Foodborne Bacteria using the Contamination Sanitization Inspection and Disinfection (CSI-D) Device
… surfaces contaminated with microorganisms using ultraviolet-C (UVC) illumination. This study aimed to determine the optimal parameters for the disinfection of foodborne bacteria using the CSI-D device. The following bacterial strains were tested: generic <em>E. coli; </em>enterohemorrhagic <em>E. …

Innovative minimal processing of mini broccoli for keeping quality and safety and enhancing bioactive compounds
… Among them, the electrolysed water (EW), ultraviolet C light (UV–C) and the superatmospheric oxygen packaging (HO) have been studied. This Ph. D. Thesis covers many of the above mentioned research needs. In addition, the real health benefits of the consumption of this kailan–hybrid …

Epithelial Cell Adhesion and Proliferation on Titanium(V) Biofunctionalized with Nanoceramic Thin Film
… nanoceramic thin film coating, with and without ultraviolet C (UVC) irradiation, on titanium(V) surface hydrophilicity, and adhesion and proliferation of human gingival keratinocytes. Materials and Methods: Polished titanium(V) disks were randomly divided into three groups: control (uncoated), …

Exploring the potential of UVC in treating superficial corneal infections
… exploration of alternative treatments. Ultraviolet C (UVC) light possesses potent broad spectrum antimicrobial activity against prokaryotic cells; bacteria, fungi, protozoa, and viruses, without demonstrating microbial resistance. Eukaryotic (mammalian) cells have an innate resistance to …

Role of Mitochondrial Dynamics and Autophagy in Removal of Helix-Distorting Mitochondrial DNA Damage
… including polycyclic aromatic hydrocarbons, ultraviolet C radiation (UVC) and mycotoxins. These lesions are irreparable and persistent in the short term, but their long-term fate is unknown. Degradation of mitochondria and mtDNA is carried out by autophagy. Autophagy is protective against …

Analysis of the S. pombe sister chromatid cohesin subunit in response to DNA damage agents during mitosis.
… strains were treated with three damaging agents, ultraviolet-C (UV-C) radiation, methyl-methane sulfonate (MMS) and phleomycin. Qualitative and quantitative data were collected which demonstrated that regardless of the damaging agent used, increasing concentrations resulted in decreased cell …
