We developed a mathematical model to compare 2 indoor remediation strategies in the aftermath of an outdoor release of 1.5 kg of anthrax spores in lower Manhattan. The 2 strategies are the fumigation approach used after the 2001 postal anthrax attack and a HEPA/vaccine plan, which relies on HEPA vacuuming, HEPA air cleaners, and vaccination of reoccupants. The HEPA/vaccine approach leads to few...

This study measured ventilation volumes and particle concentrations in indoor environments with open windows doors. In addition, the effect of airflow mode air conditioner on volume concentration variations was also measured. The fan could only provide approximately 43% during design phase. amount differed depending opening area increased by multiple or doors, even when same. No significant cha...

Four mouse hepatoma cell lines, a parent (Hepa-1c1c7) and three variants (MUL12, BPrc1, and TAOc1BPrc1) which had been derived from Hepa-1c1c7 by the fluorescence-activated cell sorter, were incubated with benzo(a)pyrene, and the metabolites were analyzed by high-pressure liquid chromatography. Among these four cell lines, Hepa-1c1c7 and MUL12 metabolized benzo(a)pyrene the most quickly and to ...

Alcohol is a potential risk factor of type 2 diabetes, but its underlying mechanism is unclear. To explore this issue, Wistar rats and mouse hepatoma cells (Hepa 1-6) were exposed to ethanol, 8 g·kg(-1) ·d(-1) for 3 months and 100 mM for 48 h, respectively. Glucose and insulin tolerance tests in vivo were performed, and protein levels of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) and gl...

Supportive environments have been used to change and influence health behaviours like smoking. While psychological and ecological theories and models demonstrate the possible influences of the environment on health-enhancing physical activity (HEPA), little is known about the effectiveness of the environmental interventions. This paper presents the results of a systematic review of studies that...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

•The public is sometimes exposed to damaging small particle aerosols including SARS-Cov-2. •During shortages, facepieces available the do not protect against aerosols. •We report designing homemade masks from home air purifier “true HEPA” filters. •These function similar an N95. Shortages of efficient filtering facepiece respirators leave vulnerable transmission infectious diseases in This stud...

BACKGROUND Facilitating and enhancing interaction between stakeholders involved in the policymaking process to stimulate collaboration and use of evidence, is important to foster the development of effective Health Enhancing Physical Activity (HEPA) policies. Performing an analysis of real-world policymaking processes will help reveal the complexity of a network of stakeholders. Therefore, the ...
