Neutrophil: A New Player In Metastatic Cancers, Mengyue Wu, Mutian Ma, Zhenya Tan, Hong Zheng, Xia Liu

Toxicology and Cancer Biology Faculty Publications

The interaction between cancer cells and immune cells is important for the cancer development. However, much attention has been given to T cells and macrophages. Being the most abundant leukocytes in the blood, the functions of neutrophils in cancer have been underdetermined. They have long been considered an “audience” in the development of cancer. However, emerging evidence indicate that neutrophils are a heterogeneous population with plasticity, and subpopulation of neutrophils (such as low density neutrophils, polymorphonuclear-myeloid-derived suppressor cells) are actively involved in cancer growth and metastasis. Here, we review the current understanding of the role of neutrophils in cancer development ...

Gender And Presence Of Children: Examining Media Uses, Informational Needs, And Source Preferences During The Flint, Michigan Water Crisis, Ashleigh M. Day, Sydney O'Shay-Wallace, Matthew W. Seeger, Shawn P. Mcelmurry

Journal of International Crisis and Risk Communication Research

In 2014, a water crisis emerged in Flint, Michigan. Using uses and gratifications theory as the guiding framework, this study examines if crisis-related media uses, informational needs, and source preferences are related to respondents’ gender and/or whether or not respondents had children. A random sample of 208 Flint residents yielded results that are largely consistent with extant research, although minor nuances were found. Media uses, preferred informational sources, and desire to receive future crisis-related health information varied between women and men. Women reported significantly higher use of Facebook and Instagram. However, there were not significant differences between genders or ...

Biofilm Forming Ability Of Bacteria Isolated From Dental Caries: With Reference To Streptococcus Species, Sonali Kaustubh Ambulkar, Vidya Tale, Abhijit Jadhav, Komal Kulkarni

Future Dental Journal of Egypt

Dental caries is formed by the group of microorganisms attached to a tooth surface embedded in a matrix of polymers. Biofilm plays an important role in the development of dental caries, plaque and other periodontal diseases. The present study is aimed to isolate, identify and characterize bacteria from dental caries. The ability of biofilm formation of these isolates was confirmed by Congo red agar method, Tube method and Microtitre plate method. High biofilm-forming bacteria were identified by 16S rRNA sequencing. Streptococcus mutans, Streptococcus anginosus, Enterococcus faecalis and Rothia dentocariosa are the predominant biofilm forming bacteria associated with dental caries.

Future Dental Journal of Egypt

Background: Polyetheretherketone (PEEK) is a material that can be used instead of normal titanium implants. PEEK is considered inert and biocompatible, however, it has been shown to possess low surface energy and that leads to decreased osteointegration with bone, Recent researches have focused on increasing the bioactivity of PEEK by modifying the surface by chemical and physical means such as plasma treated surfaces.

The Purpose of this article to evaluate peek dental implant with cold plasma surface treatment

Materials In this case series an immediately loaded peek dental implant, treated with plasma surface activation method, was used to replace anterior ...
