Use of artificial intelligence to detect dental caries on intraoral photos.

Dental caries is one of the most common diseases globally and affects children and adults living in poverty who have limited access to dental care the most. Left unexamined and untreated in the early stages, treatments for late-stage and severe caries are costly and unaffordable for socioeconomically disadvantaged families. If detected early, caries can be reversed to avoid more severe outcomes and a tremendous financial burden on the dental care system.

Weak evidence of provenance effects in spring phenology across Europe and North America.

Forecasting the biological impacts of climate change requires understanding how species respond to warmer temperatures through interannual flexible variation vs through adaptation to local conditions. Yet, we often lack this information entirely or find conflicting evidence across studies, which is the case for spring phenology. We synthesized common garden studies across Europe and North America that reported spring event dates for a mix of angiosperm and gymnosperm tree species in the northern hemisphere, capturing data from 384 North American and 101 European provenances (i.

Establishment and application of a TaqMan probe-based qPCR for the detection of Enterocytozoon hepatopenaei in shrimp Litopenaeus vannamei.

Enterocytozoon hepatopenaei (EHP) is a common parasite that invades the epithelial cytoplasm in the hepatopancreas of shrimp Litopenaeus vannamei and results in slow growth of the host shrimps to cause significant economic loss in shrimp aquaculture. In this study, a TaqMan probe-based qPCR for quantitative detection of EHP was established. A pair of specific primers and a TaqMan probe were designed based on the sequence of cysteine desulfurase gene (NFS1) of EHP.
