Abstract
Parkinson's Disease (PD) is a neurodegenerative disorder characterized by motor symptoms that result from loss of nigrostriatal dopamine (DA) cells. While L-DOPA provides symptom alleviation, its chronic use often results in the development of L-DOPA-induced dyskinesia (LID). Evidence suggests that neuroplasticity within the serotonin (5-HT) system contributes to LID onset, persistence, and severity. This has been supported by research showing 5-HT compounds targeting 5-HT1A/1B receptors and/or the 5-HT transporter (SERT) can reduce LID. Recently, vortioxetine, a multimodal 5-HT compound developed for depression, demonstrated acute anti-dyskinetic effects. However, the durability and underlying pharmacology of vortioxetine's anti-dyskinetic actions have yet to be delineated. To address these gaps, we used hemiparkinsonian rats in Experiment 1, examining the effects of sub-chronic vortioxetine on established LID and motor performance. In Experiment 2, we applied the 5-HT1A antagonist WAY-100635 or 5-HT1B antagonist SB-224289 in conjunction with L-DOPA and vortioxetine to determine the contributions of each receptor to vortioxetine's effects. The results revealed that vortioxetine consistently and dose-dependently attenuated LID while independently, 5-HT1A and 5-HT1B receptors each partially reversed vortioxetine's effects. Such findings further support the promise of pharmacological strategies, such as vortioxetine, and indicate that broad 5-HT actions may provide durable responses without significant side effects.

Abstract
Sucrose octapalmitate-d11, d24 and d248 have been synthesized. Using 2H NMR T1 and analyses of the temperature dependence of the lineshapes, a detailed description of the solid state molecular motional modes is presented. Activation energies for methyl and methylene group rotation in the fatty acyl chains have been determined. The sucrose moiety is found to be static on the solid state deuterium NMR timescale.

Abstract
Phages lytic to Vibrio vulnificus were found in estuarine waters, sediments, plankton, crustacea, molluscan shellfish, and the intestines of finfish of the U.S. Gulf Coast, but no apparent relationship between densities of V. vulnificus and its phages was observed. Phage diversity and abundance in molluscan shellfish were much greater than in other habitats. V. vulnificus phages isolated from oysters did not lyse other mesophilic bacteria also isolated from oysters. Both V. vulnificus and its phages were found in a variety of oyster tissues and fluids with lowest densities in the hemolymph and mantle fluid. These findings suggest a close ecological relationship between V. vulnificus phages and molluscan shellfish.

Abstract
Forty specimens of carotid plaque from 30 patients who had suffered cerebrovascular accidents and 10 asymptomatic control patients were examined by light and scanning electron microscopy (SEM). The SEM revealed the finely detailed surface characteristics of the plaque including cell deposits, endothelial damage, and exposed subendothelium. X-ray energy spectrography scans revealed that 7 specimens had calcium deposits. Presurgical treatment with dipyridamole and aspirin inhibited or substantially reduced thrombus formation.
