Virginia Commonwealth University is a public research university located in Richmond, Virginia. VCU was founded in 1838 as the medical department of Hampden–Sydney College, becoming the Medical College of Virginia in 1854. In 1968, the Virginia General Assembly merged MCV with the Richmond Professional Institute, founded in 1917, to create Virginia Commonwealth University. Today, more than 31,000 students pursue 222 degree and certificate programs through VCU's 13 schools and one college. The VCU Health System supports the university's health care education, research and patient care mission.With a record $256 million in sponsored research funding in the fiscal year 2011, VCU is designated as a research university with very high research activity by the Carnegie Classification of Institutions of Higher Education. A broad array of university-approved centers and institutes of excellence, involving faculty from multiple disciplines in public policy, biotechnology and health care discoveries, supports the university's research mission. Twenty-eight graduate and first-professional programs are ranked by U.S. News and World Report as among the best in the country. VCU's athletic teams compete in Division I of the NCAA and are collectively known as the VCU Rams. They are members of the Atlantic 10 Conference. The VCU campus includes historic buildings such as the Ginter House, now used by the school's provost. Wikipedia.

A family of compounds which function as selective ligands for the serotonin receptor 2B (5-HT_(2B)) is identified. Some of the compounds are synthetic non-natural ligands which have a relatively strong interaction with 5-HT2B compared to naturally occurring compounds (some of which are identified for the first time herein as ligands for 5-HT_(2B)). Because the compounds, both naturally occurring and synthetically produced, function as ligands for 5-HT_(2B )they will have application in, for example, the treatment and/or prevention of nervous system disorders such as Alzheimers disease.

The system includes various embodiments of components, including (1) a sensor array, (2) a processor, (3) a transmitter, (4) a receiver-stimulator, and (5) an implantable electrode array. The gustatory implant system generates tastant fingerprints by detecting tastants with an array of chemical sensors and then transmitting variable spatiotemporal stimulation patterns for an electrode array with electrode stimulating points positioned at different locations in the gustatory cortex (e.g., stimulating the chorda tympanic nerve). Different patterns of activity in the gustatory cortex are thereby generated which mimic the sense of taste in a subject. Once trained the system should be usable by a subject to detect or correctly identify or perceive one or more tastes. The system may also include an external electronic device for processing and displaying information to monitor ingestion of various substances in a subject.

L27 in Staphylococcus aureus and other Firmicutes is encoded with an N-terminal extension that is not present in most Gram-negative organisms and is absent from mature ribosomes. We have identified a cysteine protease, conserved among bacteria containing the L27 N-terminal extension, which performs post-translational cleavage of L27. The provided methods have utility for the development of new therapeutic antibiotics that target this novel pathway in order to kill pathogenic Firmicutes and related bacteria.

In one example implementation, a method includes receiving, at a computing device, a request to grant a set of requested permissions to an application installed on the computing device, and sending, from the computing device, a permission query request to a recommendation server, where the permission query request includes an identifier for the application, and the set of requested permissions. The method may also include receiving, at the computing device, from the recommendation server, a set of permission recommendations, where the set of permission recommendations indicates whether the recommendation server recommends granting each requested permission from the set of requested permissions. The method may also include displaying the set of requested permissions and the set of permission recommendations, determining a set of granted permissions for the application, granted by a user of the computing device, from the set of requested permissions, and setting the permissions for the application on the computing device using the set of granted permissions.

Antigenic polypeptides comprising linear immunodominant epitopes of Borrelia outer surface protein A (OspA) or Borrelia outer surface protein C (OspC) are useful as vaccines against Lyme disease, and as diagnostics for detecting Borrelia infections. The OspA and OspC antigenic polypeptides typically comprise a plurality of peptides representing epitope containing regions from multiple distinct phyletic groups. The antigenic polypeptides may also include epitopes from both Borrelia OspA and Borrelia OspC.

Methods and compositions for the prevention and treatment of liver damage or disease in a subject in need thereof are provided. The methods involve providing the sulfated oxysterol 25-hydroxycholesterol-3-sulfate (25HC3S) to the subject e.g. by 1) administering 25HC3S to the subject; or 2) overexpressing, in the subject, the hydroxysterol sulfotransferase enzyme SULT2B1b, which catalyzes the sulfation of 25-hydroxycholesterol (25HC) to form 25HC3S.

An organ protectant solution which is intravenously administered includes at least one oncotic agent and optionally a high concentration of cell-impermeant molecules. Together, they promote transfer of water from cells to interstitium and into the capillaries, thereby preventing or reducing cell swelling, maintaining blood circulation and oxygenation of tissues, and extending the Golden Hour for traumatic and/or hemorrhagic shock patients. In addition, compositions comprising PEG-20k and methods of their use for preserving and/or reanimating harvested organs ex vivo for lengthy periods of time (e.g. at least about 8-24 hours) are also provided.

A study was conducted to provide detailed information about strong ionic hydrogen bonds (IHB). These strong hydrogen bonds were critical in ionic clusters and nucleation, in electrolytes, ion solvation, and acid-base chemistry, in the structures of ionic crystals, surfaces, silicates, and clays. IHBs were also important in bioenergetics including protein folding, enzyme-active centers, formation of membranes and proton transport, and biomolecular recognition. The energetics of IHB interactions were isolated and studied quantitatively in the gas phase. These studies led to a fundamental understanding of relations between strong ionic hydrogen bond strengths and molecular structure and the solvation of ions in the critical inner shells, and acid-base phenomena and bioenergetics.

It is generally thought that autophagy has two primary and opposing functions in tumor cells in response to stress induced by chemotherapy or radiation. One is the cytoprotective function that can in theory be inhibited for therapeutic advantage by sensitizing the cells to these treatment modalities. The other is the cytotoxic function that is generally not observed with conventional treatment modalities, but that may function to promote tumor cell killing either alone or in association with apoptosis. In this commentary/review, we advance the premise that autophagy is actually populated by at least two additional players. One we have termed the nonprotective form of autophagy, where the cell is apparently carrying out autophagy-mediated degradative functions, but where autophagy inhibition does not lead to perceptible alterations in drug or radiation sensitivity. The other is what we now term the cytostatic form of autophagy in that its activation results in prolonged growth inhibition as well as reduced clonogenic survival (loss of reproductive capacity) but in the absence of actual loss of cell viability through apoptosis or necrosis; however, as is the case with cytototoxic autophagy, inhibition of cytostatic autophagy protects the tumor cell from the agent (drugs or radiation) that promotes the autophagic response. In view of current clinical efforts to exploit autophagy inhibition as a therapeutic strategy for sensitization of malignancies to chemotherapy and radiation, it is critical to recognize that if chemotherapy and/or radiation actually promote autophagy in patient tumors, the autophagy is not of necessity cytoprotective in function. © 2014 AACR.
