Was that cheating? Perceptions vary by sex, attachment anxiety, and behavior.

We generated an inventory of 27 interpersonal behaviors and examined the extent to which participants judged each behavior as cheating on a long-term partner. We predicted variation in these judgments based on participant sex and attachment insecurity. Ratings for items ranged considerably; participants rated sexual behaviors as most indicative of cheating, then erotic behaviors, followed by behaviors consistent with a romantic relationship, and then behaviors related to financial support.

Nitric oxide-dependent cilia regulatory enzyme localization in bovine bronchial epithelial cells.

Airway epithelial-derived nitric oxide (NO), through the activation of nucleotide cyclases and downstream kinases, stimulates ciliary beating, yet the precise locations of these enzymes are unknown. We hypothesized that these NO-activated enzymes are located within, or adjacent to, the ciliary axoneme. Immunohistochemistry of intact ciliated cells revealed that endothelial-type nitric oxide synthase (eNOS), the RII isoform of the cAMP-dependent protein kinase (PKA-RII), the type I isoform of the cGMP-dependent protein kinase (PKG-I), and guanylate cyclase beta (GC-beta) all colocalized with pericentrin to the basal body.
