Drivers of behavior in two tick species, and (Acari: Ixodidae), in a laboratory setting.

Ticks and tick-borne diseases are of increasing concern in the United States, and understanding tick behavior could be crucial to limiting the exposure of humans and other animals to ticks. Here, we wanted to understand the drivers of questing and burrowing in and . We used a factorial design to assess the effects of substrate (sand, soil, and rock), temperature (16° and 22° C), tick species ( and ), and competition (homogenous or heterogenous mixture of ticks in the arena) on tick behavior in laboratory arenas.

Minor Cannabinoid Profile of Unregulated Cannabidiol Products.

Although the majority of cannabinoid research has focused on delta-9-tetrahydrocannabinol (Δ-THC) and cannabidiol (CBD), there is increasing interest in the therapeutic effects of other phytocannabinoid compounds (i.e., minor cannabinoids), as there is little known about their effects or interaction with CBD.

Integrated multimodal cell atlas of Alzheimer's disease.

Alzheimer's disease (AD) is the leading cause of dementia in older adults. Although AD progression is characterized by stereotyped accumulation of proteinopathies, the affected cellular populations remain understudied. Here we use multiomics, spatial genomics and reference atlases from the BRAIN Initiative to study middle temporal gyrus cell types in 84 donors with varying AD pathologies.

Analysis of ductal carcinoma in situ by self-reported race reveals molecular differences related to outcome.

Background: Ductal carcinoma in situ (DCIS) is a non-obligate precursor to invasive breast cancer (IBC). Studies have indicated differences in DCIS outcome based on race or ethnicity, but molecular differences have not been investigated.

Methods: We examined the molecular profile of DCIS by self-reported race (SRR) and outcome groups in Black (n = 99) and White (n = 191) women in a large DCIS case-control cohort study with longitudinal follow up.
