An Assessment Of The AFL MaskĀ® And LUNA Wallmount, The New Developments In The AirPurifier Industry For Preventing The Airborne Pathogens
The current unprecedented situation with the COVID-19 (Coronavirus Disease 2019) poses a great challenge to the scientific world, demanding immediate development of technologies to fight with and prevent transmission of pathogens, especially in regards to airborne pathogens and surface contaminants. It also urges us to reevaluate designs of advanced Personal Protective Equipment (PPE). We have been working on the development and assessment of the AFL-Photo Catalytic Oxidation (AFLPCOĀ®) Nanotechnology to combat with airborne pathogens and different forms of impurities and pollutants present in the indoor air. Various types of facemasks are available in the world market and have become the most important personal protective equipment for healthcare workers and the public. Depending upon their filters, they can provide protection against dreaded contagious diseases and several types of pollution. With the current 2 spread of the COVID-19 Pandemic, facemasks and powerful air purification equipment are considered as lifesaving apparatus necessary for survival and living a healthy life. The facemasks filter fine airborne particles from reaching the respiratory system and prevent infection. We have designed a new type of facemask, AFL MaskĀ® and LUNA Wall Mount SanifierĀ® air purification unit to combat with the airborne pathogen and increased air pollution. The AFL MaskĀ® has proven to prevent the entry of the PM2.5 and airborne pathogen up to 99% and provide internal air, reducing the chances of building up moisture on the face. This newly designed AFL MaskĀ® and LUNA Wall Mount SanifierĀ® can be used to prevent the pathogens and particulate matters significantly. We also tested the LUNA Wall Mount SanifierĀ® (LNT2-6000 Model), AFL Car SanifierĀ® and AFL MaskĀ® for Ozone emission. All the equipment tested were proven safe to international standards in terms of Ozone emission.

Cost analysis of noninvasive blood-based microRNA testing versus CT scans for follow-up in patients with testicular germ-cell tumors
BACKGROUND: Our group has developed a noninvasive blood-based microRNA (miRNA) test for improving diagnosis, disease monitoring, and relapse detection in malignant testicular germ-cell tumors (TGCTs). Performance analysis suggests the test is likely to have comparable sensitivity and specificity in detecting TGCT as computed tomography (CT), thus reducing the need for serial CT scans for follow-up monitoring, with associated reductions in cumulative radiation burden and second cancer risk. To facilitate clinical adoption, we undertook a cost analysis to identify the budget impact of replacing CT scans with miRNA testing within health care systems. METHODS: The TGCT aftercare pathway was mapped out using National Comprehensive Cancer Network guidelines. A Markov model was built to simulate the impact of the miRNA test on TGCT aftercare costs. Incidence, treatment probabilities, relapse rate, and death rate data were collected from published studies to populate the model. RESULTS: Applying our model to the US health care system, the miRNA test has the potential to save up to $69 million per year in aftercare expenses related to TGCT treatment, with exact savings depending on the adoption rate and test price. CONCLUSION: This analysis demonstrates the potential positive budget impact of adopting miRNA testing in place of CT scans in the clinical management of TGCTs
Mercury in Hair Is Inversely Related to Disease Associated Damage in Systemic Lupus Erythematosus.
Systemic lupus erythematosus (SLE) is an autoimmune inflammatory disease, and environmental factors are proposed to exacerbate existing symptoms. One such environmental factor is mercury. The aim of this study was to investigate the relationship between exposure to mercury (Hg) and disease activity and disease associated damage in Total Hg concentrations in hair and urine were measured in 52 SLE patients. Dental amalgams were quantified. Disease activity was assessed using three indexes including the British Isles Lupus Assessment Group Index (BILAG). Disease associated damage was measured using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology SLICC/ACR Damage Index. Pearsonās correlation identified a significant negative correlation between hair Hg and BILAG (r = ā0.323, p = 0.029) and SLICC/ACR (r = ā0.377, p = 0.038). Multiple regression analysis identified hair Hg as a significant predictor of disease associated damage as determined by SLICC/ACR (Ī² = ā0.366, 95% confidence interval (CI): ā1.769, ā0.155 p = 0.019). Urinary Hg was not related to disease activity or damage. Fish consumption is the primary route of MeHg exposure in humans and the inverse association of hair Hg with disease activity observed here might be explained by the anti-inflammatory effects of n-3 long chain polyunsaturated fatty acids also found in fish
Selfie-Objectification:Self-Objectification and Positive Feedback (āLikesā) are Associated with Frequency of Posting Sexually Objectifying Self-Images on Social Media
The present study is the first to examine the extent to which young adult women post objectifying self-images on social media, and whether the frequency of posting such content can be predicted by self-objectification and positive feedback (likes). Eighty-six young adult women from the UK (Age M = 19.88; SD = 1.34, Range = 18-24) completed self-report measures of self-objectification and social media use. The 20 most recent images they had posted on their personal Instagram accounts were downloaded (Image N = 1720) and content analysed for self-objectifying content. The analysis found that 29.77% of participantsā Instagram images were objectified, though there were individual differences. Higher frequency of posting objectified self-images was associated with trait self-objectification and receiving more likes on this type of self-image, relative to non-objectified self-images. The implications of the novel findings for objectification theory are discussed within
GSK-3Ī² Function in Bone Regulates Skeletal Development, Whole-Body Metabolism, and Male Life Span
Glycogen synthase kinase 3 Ī² (GSK-3Ī²) is an essential negative regulator or ābrakeā on many anabolic-signaling pathways including Wnt and insulin. Global deletion of GSK-3Ī² results in perinatal lethality and various skeletal defects. The goal of our research was to determine GSK-3Ī² cell-autonomous effects and postnatal roles in the skeleton. We used the 3.6-kb Col1a1 promoter to inactivate the Gsk3b gene (Col1a1-Gsk3b knockout) in skeletal cells. Mutant mice exhibit decreased body fat and postnatal bone growth, as well as delayed development of several skeletal elements. Surprisingly, the mutant mice display decreased circulating glucose and insulin levels despite normal expression of GSK-3Ī² in metabolic tissues. We showed that these effects are due to an increase in global insulin sensitivity. Most of the male mutant mice died after weaning. Prior to death, blood glucose changed from low to high, suggesting a possible switch from insulin sensitivity to resistance. These male mice die with extremely large bladders that are preceded by damage to the urogenital tract, defects that are also seen type 2 diabetes. Our data suggest that skeletal-specific deletion of GSK-3Ī² affects global metabolism and sensitizes male mice to developing type 2 diabetes. (Endocrinology 154: 3702ā3718, 2013
Enhanced interferon regulatory factor 3 binding to the interleukin-23p19 promoter correlates with enhanced interleukin-23 expression in systemic lupus erythematosus.
OBJECTIVE: To examine the role of interferon regulatory factor 3 (IRF-3) in the regulation of interleukin-23 (IL-23) production in patients with systemic lupus erythematosus (SLE).
METHODS: Bone marrow-derived macrophages were isolated from both wild-type and IRF3(-/-) C57BL/6 mice. These cells were stimulated with the Toll-like receptor 3 (TLR-3) agonist poly(I-C), and IL-23p19 cytokine levels were analyzed by enzyme-linked immunosorbent assay. IRF-3 binding to the IL-23p19 gene promoter region in monocytes from patients with SLE and healthy control subjects was analyzed by chromatin immunoprecipitation (ChIP) assay. Luciferase reporter gene assays were performed to identify key drivers of IL-23p19 promoter activity. TANK-binding kinase 1 (TBK-1) protein levels were determined by Western blotting.
RESULTS: ChIP assays demonstrated that IRF-3 was stably bound to the human IL-23p19 promoter in monocytes; this association increased following TLR-3 stimulation. Patients with SLE demonstrated increased levels of IRF-3 bound to the IL-23p19 promoter compared with control subjects, which correlated with enhanced IL-23p19 production in monocytes from patients with SLE. Investigations of the TLR-3-driven responses in monocytes from patients with SLE revealed that TBK-1, which is critical for regulating IRF-3 activity, was hyperactivated in both resting and TLR-3-stimulated cells.
CONCLUSION: Our results demonstrate for the first time that patients with SLE display enhanced IL-23p19 expression as a result of hyperactivation of TBK-1, resulting in increased binding of IRF-3 to the promoter. These findings provide novel insights into the molecular pathogenesis of SLE and the potential role for TLR-3 in driving this response
The distribution of burden of dental caries in schoolchildren: a critique of the high-risk caries prevention strategy for populations
BACKGROUND: The 'high-risk approach' is a commonly adopted strategy recommended for the prevention of dental caries in populations. The scientific basis for the strategy has been questioned. The objective of this study is to assess the contribution that children identified at 'high-risk' made towards the total of new caries lesions over a 4-year period, by analysing the distribution of new lesions per 100 children. METHODS: Data are from the National Preventive Dentistry Demonstration Programme (NPDDP) in the United States. The analyses identified the distribution of new carious lesions over a 4-year period in four groups of 7 year-old children who received differing preventive regimes. RESULTS: The majority of new lesions occurred in those children classified at lowest caries risk at baseline. Irrespective of the preventive regime adopted and the initial caries levels, children classified as 'highest risk' contributed less than 6% of the total number of new lesions developing over 4 years. CONCLUSION: These findings challenge the basis for the adoption of a high-risk strategy
Grouping of tooth surfaces by susceptibility to caries: a study in 5ā16 year-old children
BACKGROUND: The decline in caries has slowed and this may be indicative of variation in the susceptibility of differing teeth to caries. This study tests the hypothesis that in children, there are groups of tooth sites that exhibit differences in caries susceptibility. METHODS: Probit analysis of caries data collected from a 4-year longitudinal study of 20,000 schoolchildren aged between 5 and 16 years in 10 differing locations in the United States. RESULTS: The development of dental caries within the mouth followed a fixed hierarchy indicating that tooth surfaces show variation in caries susceptibility. Certain teeth and tooth sites have similar susceptibilities and can be grouped, the sizes of the groups vary. The most susceptible group consists of six tooth surfaces: the buccal pits and occlusal fissured surfaces of the first molar teeth. The second group consisted of 12 sites on the second molar and premolar teeth. The group formed by the least susceptible sites included the largest number of tooth surfaces and consists of the majority of the lower anterior teeth and canines. CONCLUSION: Variation in the caries susceptibility of tooth surfaces exists. Surfaces can be grouped according to caries susceptibility. An effect that reduces the cariogenic challenge of one of the sites within a group is likely to affect all the other sites within the particular group
