Novel Histopathologic Features of Diffuse Blue‐Gray Hyperpigmentation Associated With Kratom Use: A Case Report and Literature Review

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Drug‐induced hyperpigmentation accounts for 10%–20% of acquired pigmentary disorders and can be misdiagnosed for other causes such as melasma, post inflammatory changes, or heavy metal deposition. Kratom (Mitragyna speciosa), a Southeast Asian plant with an opioid‐like profile, has been increasingly used in the United States for ...

When Similar Individuals Don't Attract: Absence of Assortative Mating by Coloration in a Damselfly With Honest Signaling

Ethology, EarlyView.
In Acanthagrion lancea damselflies, both sexes display blue ornamentation, but do they choose mates based on it? We tested whether mutual mate choice and time constraints influence ornament evolution. Blue coloration correlated with individual quality, but individuals did not choose mates based on color, and this was unaffected by time constraints over

Limbal cystotomy by fine needle aspiration of a translucent iris cyst in a horse

Equine Veterinary Education, EarlyView.
Summary A 4‐year‐old Cremello crossbred mare was referred to the Equine Veterinary Teaching Hospital of Utrecht University for a translucent iris cyst from the dorsal pupillary margin corpora nigra in the right eye. Although noninvasive diode laser treatment is the preferred method of pigmented cyst ablation, two attempts did not result in disruption ...

Field‐based evidence of impaired sperm quality associated with conventional farming in two passerine birds

Ibis, EarlyView.
The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,
