PURPOSE Determine acceptance of and compliance with intranasal cobalamin (vitamin B12) replacement therapy. METHODS Veteran subjects were recruited from VA Outpatient facilities in Hawai'i. Information was obtained by interview and medical record review. Subjects received the standard dose of intranasal cobalamin of 500 micrograms intranasally, once a week. A follow-up questionnaire was admin...

Although the blood-brain barrier (BBB) restricts access to the central nervous system (CNS) for the use of systemically administered therapies, an alternative approach, the non-invasive method of intranasal delivery, can rapidly target delivery of molecules to the CNS. Intranasal delivery has the distinct advantages of circumventing the BBB while minimizing systemic exposure. This novel approac...

Of several newer delivery systems under development and investigation for the administration of opioids, the intranasal route has received a substantial amount of attention. Intranasal administration is a convenient form of delivery that is applicable to several opioids. It has the potential for self-administration, combined with a rapid onset of action, allowing for patient-controlled analgesi...

Administering diazepam intravenously or rectally in an adult with status epilepticus can be difficult and time consuming. The aim of this study was to examine whether intranasal diazepam is an effective alternative to intravenous diazepam when treating status epilepticus. We undertook a retrospective cohort study based on the medical records of 19 stroke patients presenting with status epilepti...

Bioassay-guided fractionation of extracts from temperate Australian collections of the marine sponge Pseudoceratina purpurea resulted in the isolation and characterisation of two new and six known bromotyrosine-derived alkaloids with antibiotic activity. Surprisingly, a single specimen of the mollusc Tylodina corticalis, which was collected while feeding on P. purpurea, contained only a few of ...

The sponge construction, designed by Bertoni, Daemen, Peeters, and Ass­ cheis, is the framework for hash functions such as Keccak, PHOTON, Quark, and spon­ gent. The designers give a keyed sponge construction by prepending the message with key and prove a bound on its pseudorandomness in the ideal permutation model . In this paper we give a different keyed sponge construction that is based on t...

Caribbean coral reefs have been transformed in the past few decades with the demise of reef-building corals, and sponges are now the dominant habitat-forming organisms on most reefs. Competing hypotheses propose that sponge communities are controlled primarily by predatory fishes (top-down) or by the availability of picoplankton to suspension-feeding sponges (bottom-up). We tested these hypothe...

Despite the large number of reports describing sponge-microbe associations, limited knowledge is available about associated fungi and their relationships with the hosts. In this work, specific fungal strains were obtained directly from in vitro sponge cell cultures (primmorphs) and single sponge cells (cytospins) and compared with those obtained from whole tissue preparations. A total of 27 fun...

Sponges are abundant, diverse and functionally important organisms of coral reef ecosystems. Sponge-associated microorganisms have been receiving greater attention because of their significant contribution to sponge biomass, biogeochemical cycles and biotechnological potentials. However, our understanding of the sponge microbiome is limited to a few species of sponges from restricted geographic...

Title of Dissertation: ROLES OF THE SYMBIOTIC MICROBIAL COMMUNITIES ASSOCIATED WITH SPONGE HOSTS IN THE NITROGEN AND PHOSPHORUS CYCLES Fan Zhang, Doctor of Philosophy, 2015 Directed By: Dr. Russell T. Hill, Professor, Institute of Marine and Environmental Technology, University of Maryland Center for Environmental Science Marine sponges are habitat-forming organisms in coral reefs. Many sponge ...
