Dinosaurs had a "rostral nostril," says Science researcher

As a human, the rostral nostril might not seem like a big deal: our own bony nostril is relatively small, leaving little dou...Structure of pain-modulating enzyme described by scientists at the Scripps Research Institute
...lus. THC binds to "CB-1" receptors on cells on the rostral ventromedial medulla, a pain-modulating center of the brain, decreasing sensitivity to pain. Unfortunately, the receptors that THC bind to are also widely expressed in other parts of the brain, such as in the memory and information-processing centers...... These Six3-mutant mice died at birth, lacking the rostral forebrain and most anterior head structures, like ...rritories. We have now determined that in the most rostral region, Six3 expression is required in order to guarantee that no Wnt1 protein will reach that terri...St. Jude researchers show that the Six3 gene is vital in the creation of the brains complexity
...ish, similar to the Six3-/- mice, the anterior, or rostral part of the head is missing due to the abnormal extension of Wnt1 activity into this region. When the researchers injected genetic material (messenger RNA, or mRNA) for mouse Six3 into the mutant zebrafish embryos, these mutant embryos developed a no...Childhood sleep-disordered breathing severity related to tonsil size, oropharyngeal volume
...e to the posterior wall of the pharynx defined the rostral limit of the oropharynx, while the tip of the epiglottis defined the caudal margin. Data Analysis: Subjects were divided into two groups: one with high- (>7) and one with low- (<4) OAHI values. Researchers used ANOVA, followed by the Stud...
