Cariogenic Potential of Human and Bovine Milk on Enamel Demineralization.

Caries Res 2021 Jun 15:1-8. Epub 2021 Jun 15.

Piracicaba Dental School, UNICAMP, Piracicaba, Brazil.

The higher cariogenicity of human milk when compared with bovine milk is still a debatable subject. Therefore, we evaluated the effect of human or bovine milk exposure on biofilm composition and enamel demineralization using a validated cariogenic biofilm model. Streptococcus mutans UA159 biofilms (n = 8) were grown on human saliva-coated bovine enamel slabs of known surface hardness. Read More

Accid Anal Prev 2021 Jun 12;159:106225. Epub 2021 Jun 12.

University of Connecticut Psychological Sciences Department, USA.

During the COVID-19 stay-at-home period there were observed increases in both the percentage of cars engaged in extreme speeding, and the percentage of cars traveling below the speed limit. These changes have been attributed to unusually low traffic volume during the stay-at-home period. We develop a novel theoretical account, based on existing empirical research, of perceptual and psychological processes that may account for changes in speeding behavior under low traffic volume conditions.

Plant Physiol Biochem 2021 Jun 8;166:270-277. Epub 2021 Jun 8.

Institute of Soil and Water Resources, ELGO-DEMETER, Thessaloniki, 57001, Greece. Electronic address:

The benefits of silicon against abiotic stress in different annual plant species have been described in many studies, however the regulation of ripening of fruit tree crops by silicon remains largely uncharacterized. Therefore, the present study aimed to explore the impact of foliar silicon application in the apple (cv. 'Fuji') fruit ripening traits along with the effect of silicon in the nutrient and metabolic changes in the fully expanded leaves, annual shoots, fruit outer pericarp (peel) and fruit mesocarp (skin) tissues.

Enriched Random Forest for High Dimensional Genomic Data.

IEEE/ACM Trans Comput Biol Bioinform 2021 Jun 15;PP. Epub 2021 Jun 15.

Ensemble methods such as random forest works well on high-dimensional datasets. However, when the number of features is extremely large compared to the number of samples and the percentage of truly informative feature is very small, performance of traditional random forest decline significantly. To this end, we develop a novel approach that enhance the performance of traditional random forest by reducing the contribution of trees whose nodes are populated with less informative features.

Metformin reverses the effects of high glucose on human dermal fibroblasts of aged skin via downregulating RELA/p65 expression.

J Physiol Biochem 2021 Jun 15. Epub 2021 Jun 15.

Department of Medical Biology, Faculty of Medicine, Istanbul University-Cerrahpasa, Istanbul, Turkey.

Metformin has been successfully used as an anti-aging agent but exact molecular mechanisms of metformin in anti-aging remain unknown. Hyperglycemia during skin aging not only causes oxidative damage to cellular macromolecules, like dermal collagen, but also modulates the activation of transcription factor nuclear factor kappa B (NF-kB). We aimed to investigate in vitro effects of high glucose (HG) and metformin treatment on proliferation and apoptosis of human primary dermal fibroblasts (HDFs), and the expression of COL1A1, COL3A1, and RELA/p65 genes.

Enhanced efficiency of nonviral direct neuronal reprogramming on topographical patterns.

Biomater Sci 2021 Jun 15. Epub 2021 Jun 15.

Department of Chemical Engineering, University of Waterloo, 200 University Ave. W, Waterloo, Ontario N2L 3G1, Canada.

Nonviral direct neuronal reprogramming holds significant potential in the fields of tissue engineering and regenerative medicine. However, the issue of low reprogramming efficiency poses a major barrier to its application. We propose that topographical cues, which have been applied successfully to enhance lineage-directed differentiation and multipotent stem cell transdifferentiation, could improve nonviral direct neuronal reprogramming efficiency.
