Females display vigorously towards courting males after copulating (female-male aggression), as well as fight for and defend nest sites against other females (female-female aggression). To understand the neuroendocrine basis of this aggressive behavior, we examined changes in testosterone (T), estradiol (E2), corticosterone (CORT), and progesterone (P4) during the mating and nesting periods, and then air jordan canada measured levels in nesting females captured during aggressive interactions.
The possible roles that contact plays in attitudes formation include: (1) normalizing homosexuality, (2) challenging previously held myths and stereotypes, and (3) increasing a person’s likelihood of having contact experiences with gay men and developing gay-supportive attitudes. Participants described the quality of the contact as taking place air jordans canada in the context of a friendship that developed between them and a gay male that strengthened after the gay friend came out. Furthermore, the impact of these contact experiences did not change fag hags’ sense of morality, but “improved” their attitudes toward gay men.
OBJECTIVE: To determine how filler content and an acidic environment affect the retention of sealants placed on smooth enamel surfaces.MATERIALS AND METHODS: A sample of 120 teeth was randomly divided into six subsamples. Three experimental sealants with identical formulas, with the exception of the amount of filler content (18%, 30%, 50%), were applied according to manufacturers’ recommendations. Half of the subsamples were exposed to an acid environment (pH of 2.5) for 96 hours.
All 15 children with awake apnea had frequent episodes of gastroesophageal reflux. Treatment with home monitoring and reflux precautions was successful in 10 of 15. Five children received therapy with urecholine hydrochloride because of continuing episodes of reflux-associated apnea.
Three-dimensional (3-D) analysis of airway trees extracted from computed tomography (CT) image data can provide objective information about lung structure and function. However, manual analysis of 3-D lung CT images is tedious, time consuming and, thus, impractical for routine clinical care. We have previously reported an automated rule-based method for extraction of airway trees from 3-D CT images using a priori knowledge about airway-tree anatomy.
A better understanding of osteogenesis at genetic and biochemical levels is yielding new molecular entities that can modulate bone regeneration and potentially act as novel therapies in a clinical setting. These new entities are motivating alternative approaches for bone repair by utilizing DNA-derived expression systems, as well as RNA-based regulatory molecules controlling the fate of cells involved in osteogenesis. These sophisticated mediators of osteogenesis, however, pose unique delivery challenges that are not obvious in deployment of conventional therapeutic agents.
