The Sexually Dichromatic Use of Chromatophores for Cryptic Coloration in the Shrimp .

AbstractSexual dimorphism typically arises as a result of sexual selection or sex-specific natural selection. Species that exhibit cryptic coloration provide an excellent system for studying sex-specific selection for sexual dichromatism. In this study, we examined the sexually dichromatic use of chromatophores in the seawhip shrimp, (Borradaile, 1920), which commonly resides on colonies of (Lamarck, 1815), a gorgonian octocoral that occurs in multiple color morphs.

Pan-tumor validation of a NGS fraction-based MSI analysis as a predictor of response to Pembrolizumab.

Microsatellite instability high (MSI-H) and mismatch repair deficient (dMMR) tumor status have been demonstrated to predict patient response to immunotherapies. We developed and validated a next-generation sequencing (NGS)-based companion diagnostic (CDx) to detect MSI-H solid tumors via a comprehensive genomic profiling (CGP) assay, FoundationOne®CDx (F1CDx). To determine MSI status, F1CDx calculates the fraction of unstable microsatellite loci across >2000 loci using a fraction-based (FB) analysis.

Amygdala and Cortex Relationships during Learning of a Sensory Discrimination Task.

During learning of a sensory discrimination task, the cortical and subcortical regions display complex spatiotemporal dynamics. During learning, both the amygdala and cortex link stimulus information to its appropriate association, for example, a reward. In addition, both structures are also related to nonsensory parameters such as body movements and licking during the reward period.

The Rare Presentation of Multiple Chondroid Syringomas in One Patient: A Case Report.

Chondroid syringomas are rare, benign tumors originating from sweat glands occurring as singular lesions of the head and neck. This case report presents a patient in whom multiple chondroid syringoma lesions were found. Thus illuminating the possibility for such occurrences in the future of which physicians should be aware.

Sea urchin mass mortalities 40 y apart further threaten Caribbean coral reefs.

In 1983 to 1984, a mass mortality event caused a Caribbean-wide, >95% population reduction of the echinoid grazer, . This led to blooms of algae contributing to the devastation of scleractinian coral populations. Since then, exhibited only limited and patchy population recovery in shallow water, and in 2022 was struck by a second mass mortality reported over many reef localities in the Caribbean.
