Lack of Herpes Simplex Virus (HSV) vaccine, low vaccination rates of Influenza viruses, waning immunity and viral transmission after vaccination underscore the need to reduce viral loads at their transmission sites. Oral virus transmission is several orders of magnitude higher than nasal transmission. Therefore, in this study, we evaluated neutralization of viruses using a natural viral trap protein (FRIL) formulated in clinical-grade chewing gum.

While deep learning is increasingly used, it is difficult to generalize due to variability at the level of cells, neighborhoods, and niches in health and disease. To address this, we developed TACIT, an unsupervised algorithm for cell annotation using predefined signatures that operates without training data.

Methods: This cross-sectional study describes the prevalence of maternal and child UPF/SSB consumption and the factors associated with frequent consumption in a convenience sample of 749 children ages 6 months through 6 years and their mothers participating in a community-based child oral health program in five informal settlement communities in Mumbai, India. Mothers were interviewed regarding maternal and child oral health and nutrition characteristics, including consumption of beverages and foods associated with tooth decay-milk, soda, tea with sugar, sweets, and chips/biscuits-using standardized questionnaires.
Biologics are unaffordable to a large majority of the global population because of prohibitively expensive fermentation systems, purification and the requirement for cold chain for storage and transportation. Limitations of current production and delivery systems of biologics were evident during the recent pandemic when <2.5% of vaccines produced were available to low-income countries and ∼19 million doses were discarded in Africa due to lack of cold-chain infrastructure.

Childhood caries experience is influenced by family characteristics and oral health practices in the context of many social-commercial determinants. The aim of this study was to explore the relationship between families' number of children, oral health practices and child caries experience in a convenience sample of 1374 children aged 6 months through 6 years and their families from Ecuador, Nepal, and Vietnam. Data were collected by mother interviews and child dental exams.

Health care professionals are acutely susceptible to COVID-19 exposure, ultimately leading to elevated levels of anxiety and mental illness. For example, dental professionals are at high risk due to their close work with the oral cavity.

In omicron nasopharyngeal (NP) samples, the microbubble count (based on N-antigen) was significantly reduced by 20 μg of FRIL (p < 0.0001) and 0.

Recently tele-medicine has emerged as a vital resource for interdisciplinary healthcare professionals to provide critical medical care on the frontlines during the combined COVID-19 pandemic and the drug and opioid crisis. With the recent 2020 expansion of insurance coverage of telemedicine services by the United States Centers for Medicare & Medicaid Services, there has been an uptick in the need to understand how to comprehensively train physicians and health care professionals on telemedicine during a public health crisis.

Powered toothbrushes are viewed as more effective at removing plaque; however, the conflicting evidence and considerable unexplained heterogeneity in their clinical outcomes does not corroborate the relative merits of powered tooth brushing. To explain the heterogeneity of brushing patterns with powered toothbrushes, we conducted a observational study of tooth brushing practices of 12 participants in their naturalistic setting.

Specifically, spectroscopic methods are used to characterize the structure of supramolecular hydrogels on the atomic and molecular scales. Diffraction techniques rely on measurements of crystallinity and help in analyzing the structure of supramolecular hydrogels, whereas microscopy allows researchers to inspect these hydrogels at high resolution and acquire a deeper understanding of the morphology and structure of the materials.
