In Syrian hamsters, vasopressin (AVP) in the medial preoptic-anterior hypothalamus (MPOA-AH) controls a form of scent marking called flank marking. Another neurochemical signal that may interact with AVP to control flank marking is glutamate. We tested the hypothesis that glutamate interacts with AVP in the MPOA-AH to regulate flank marking. On day 1, AVP was microinjected into the MPOA-AH. On day 2, AVP was microinjected as a cocktail combining either AP-5, a NMDA antagonist, or GAMS, a non-NMDA antagonist or propranolol, a β norepinephrine antagonist. On day 3, AVP alone was microinjected. Hamsters engaged in high levels of marking in response to AVP alone or to a combination of AVP and propranolol. In contrast, the frequency of marking was significantly reduced in response to a combination of either AVP and AP-5 or AVP and GAMS. These data support the hypothesis that stimulation of flank marking by AVP within the MPOA-AH requires the activity of glutamate.

The article discusses the need for a low-cost, self-contained precision approach capability to be fielded into the F/A-18 Hornet, the premier naval strike aircraft in the U.S. The precision approach capability is necessary to increase the F/A-18 Hornet's mission effectiveness and safety. Also cited are the issues' implications for aviation and the U.S. Marine Corps.

Computer simulations of the co-adsorption of water and methanoic acid at a range of surface features of calcite and fluorite minerals have shown that the relative adsorption energies for the two minerals are reversed when solvent effects are included in the calculations, a finding which is important in the search for effective surfactant reagents in flotation techniques, which are used extensively in the mining and pharmaceutical industries and in environmental remediation processes.

Human papillomavirus (HPV) is recognized as the key risk factor for a distinct subset of oropharyngeal squamous cell carcinoma. P16 is a reliable, sensitive surrogate marker for HPV and confers a positive prognostic advantage. Basaloid differentiation on hematoxylin and eosin (H&E) staining is anecdotally noted by some pathologists to be associated with p16 positivity. This association, however, has not been adequately quantified in the literature, nor has the prognostic implications of basaloid differentiation been described.
