An electronic catheter stethoscope measures and analyzes acoustic fields and dynamic pressure variations in the gaseous or liquid fluid inside a conventional medical catheter that is positioned in a patients urologic, digestive, reproductive, cardiovascular, neurological or pulmonary system. Measurement transducers are installed in a housing connectable to multiple preselected medical catheters. The transducers detect bodily functions that are transmitted to the preselected catheter from within the body. The transducers, housing, electrical interface and signal processing electronics are positioned outside the body.


The inventors have determined, contrary to the prior art and experience, how to successfully use triciribine to treat esophogeal adenocarcinoma by one or a combination of (i) administering triciribine only to patients which according to a diagnostic test described below, exhibit enhanced sensitivity to the drug; (ii) use of a described dosage level that minimizes the toxicity of the drug but yet still exhibits efficacy; or (iii) use of a described dosage regimen that minimizes the toxicity of the drug.

Blood brain barrier (BBB) permeabilizers, such as mannitol, can facilitate the entry of stem cells from the periphery to the stroke brain. It is unknown whether BBB permeation in the chronic stage of the disease still facilitates the entry of stem cells from the periphery to the injured brain. Evidence herein shows BBB permeation in the chronic stage of stroke assisted in the entry of stem cells from the periphery to the stroke brain. Stroke models treated with human umbilical cord stem cells (hUCBC) only (2 million viable cells), mannitol or a combination. Results revealed that hUCBC alone or combined with mannitol displayed significant behavioral and histological deficits compared to control animals, with the HUCBC-mannitol combined treatment showing improvements over hUCBC only treatments in brain cell survival in the peri-infarct area. BBB permeation in chronic stroke also lowers the effective stem cell dose necessary to improve functional outcomes.

Synthetically-derived S,S-heterodisubstituted disulfides that exhibit potent in vitro antibacterial activity against a variety of bacteria, including Staphylococcus aureus, methicillin-resistant Staphylococcus aureus and Francisella tularensis. The present invention provides compounds, methods and compositions effective to treat microbial/bacterial infections, and, especially, infections arising from bacteria which have developed resistance to conventional antibiotics.

Novel antimicrobial compounds and associated methods of development are presented herein.


Patent
University of South Florida | Date: 2016-10-13

The present invention is directed to a novel class of antimicrobial agents called -AApeptides. The current invention provides various categories of -AApeptides, for example, linear -AApeptides, cyclic -AApeptides, and lipidated -AApeptides. -AApeptides of the current invention are designed to exert antimicrobial activity while being stable and non-toxic. -AApeptides also do not appear to lead to the development of microbial resistance in treated microorganisms. Thus, the disclosed -AApeptides can be used for the treatment of various medical conditions associated with pathogenic microorganisms.

Annual Review of Marine Science | Year: 2012

Over the past two decades, marine virology has progressed from a curiosity to an intensely studied topic of critical importance to oceanography. At concentrations of approximately 10 million viruses per milliliter of surface seawater, viruses are the most abundant biological entities in the oceans. The majority of these viruses are phages (viruses that infect bacteria). Through lysing their bacterial hosts, marine phages control bacterial abundance, affect community composition, and impact global biogeochemical cycles. In addition, phages influence their hosts through selection for resistance, horizontal gene transfer, and manipulation of bacterial metabolism. Recent work has also demonstrated that marine phages are extremely diverse and can carry a variety of auxiliary metabolic genes encoding critical ecological functions. This review is structured as a scientific "truth or dare," revealing several well-established "truths" about marine viruses and presenting a few "dares" for the research community to undertake in future studies.

Surface Science Reports | Year: 2012

Graphene, a single atomic layer of sp 2 hybridized carbon, exhibits a zero-band gap with linear band dispersion at the Fermi-level, forming a Dirac-cone at the K-points of its Brillouin zone. In this review, we focus on basic materials science issues of this intriguing material. The scope of this work is further narrowed by concentrating on graphene grown at transition metal surfaces, mostly under vacuum conditions, and neglecting other graphene synthesis approaches, namely growth on SiC or by graphene oxide reduction. Thus one large section of this review focuses on metal/graphene interfaces. We summarize recent surface science studies on the structure, interaction, and the growth of graphene on various metals. Metal supported graphene is a recurring theme throughout this review as it provides model-systems for studying adsorption and graphene modifications on well-defined, large area samples, and thus is ideal for employing surface science techniques. Other aspects of graphene are also reviewed. Approaches for creating and characterizing graphene nanostructures, in particular graphene nanoribbons, are discussed. Graphene nanoribbons play an important role for potential electronic applications because the lateral electron confinement in the ribbons opens a band-gap in graphene. Materials issues of nanoribbons, like formation of well-defined edges are introduced. Atomic-scale defect-structures in graphene are another topic. The known defect structures in graphene are categorized and atomic scale characterization of these defects by scanning tunneling microscopy (stocktickerSTM) and high resolution transmission electron microscopy (TEM) is illustrated. Important for applications of graphene is our ability of modifying its properties. Therefore, studies of substitutional doping of graphene with nitrogen or boron, hydrogenation or fluorination of graphene, and the adsorption of molecules with strong electron affinity are included in this review. This review is restricted to a summary of surface science studies on well-ordered systems. Other important graphene research areas such as transport measurements on pure and modified graphene are not included. The goal of this review is to give a concise overview of the materials science of graphene from the surface science perspective. © 2011 Elsevier B.V. All rights reserved.
