Will the increased use of ring lights during the coronavirus pandemic lead to a growing burden of macular degeneration?
Stanhope J, Weinstein P. Stanhope J, et al. Med Hypotheses. 2023 Jun;175:111064. doi: 10.1016/j.mehy.2023.111064. Epub 2023 Mar 28. Med Hypotheses. 2023. PMID: 37144026 Free PMC article.
One such change is an increase in the use of videoconferencing for communication with friends, family and work colleagues, and doing presentations, while physically distancing. We demonstrate an increase in the use of ring lights during the pandemic, and argue that this in …

Assessing soil microbes that drive fairy ring patterns in temperate semiarid grasslands.
Li J, Guo L, Wilson GWT, Cobb AB, Wang K, Liu L, Zhao H, Huang D. Li J, et al. BMC Ecol Evol. 2022 Nov 5;22(1):130. doi: 10.1186/s12862-022-02082-x. BMC Ecol Evol. 2022. PMID: 36335298 Free PMC article.
Soil microbial community biomarkers indicate shifts in relative microbial biomass as fairy rings expand. Inside the ring, plant roots showed greater damage from pathogenic fungi, compared to outside or ring-edge. ...However, as the ring expands, L. chinensis …

Signet-ring cell dermatofibroma.
Garrido-Ruiz MC, Carrillo R, Enguita AB, Peralto JL. Garrido-Ruiz MC, et al. Am J Dermatopathol. 2009 Feb;31(1):84-7. doi: 10.1097/DAD.0b013e31818981ff. Am J Dermatopathol. 2009. PMID: 19155733
Signet-ring cell formation, however, has never been described in dermatofibroma. We present, for the first time, a new, distinctive variant of dermatofibroma, so-called signet-ring cell dermatofibroma, in a 16-year-old man with a slowly growing skin tumor on …
