Out With The Old, In With The New: Best Practices For Replacing Library Signage, Mark Aaron Polger, Amy F. Stempler

Publications and Research

Signage is an essential way of communicating with users and is a vital way to alert patrons to important information, news, upcoming events, policies, and directions. Literature on library signage has emphasized the importance of consistency and clarity, to avoid clutter and contradictory messaging, and the need for buy-in from library staff, faculty and patrons. However, few scholarly studies address user preferences in signage. This article fills the void between theory and practice, and offers step-by-step details for revamping signage, specifically in an academic library. At the heart of the authors’ thesis is that library signs are living documents. Libraries …

Self-Assembled Hydrogel Fibers For Sensing The Multi-Compartment Intracellular Milieu, Praveen Kumar Vemula, Jonathan E. Kohler, Amy Blass, Miguel Williams, Chenjie Xu, Lynna Chen, Swapnil R. Jadhav, George John, David I. Soybel, Jeffrey M. Karp

Publications and Research

Targeted delivery of drugs and sensors into cells is an attractive technology with both medical and scientific applications. Existing delivery vehicles are generally limited by the complexity of their design, dependence on active transport, and inability to function within cellular compartments. Here, we developed self-assembled nanofibrous hydrogel fibers using a biologically inert, low-molecular-weight amphiphile. Self-assembled nanofibrous hydrogels offer unique physical/mechanical properties and can easily be loaded with a diverse range of payloads. Unlike commercially available E. coli membrane particles covalently bound to the pH reporting dye pHrodo, pHrodo encapsulated in self-assembled hydrogel-fibers internalizes into macrophages at both physiologic (37°C) and …

Multilocus Coalescent Analyses Reveal The Demographic History Of Mouse Lemur Sister Species., Christopher Blair, Kellie L. Heckman, Amy L. Russell, Anne D. Yoder

Publications and Research

Debate continues as to whether allopatric speciation or peripatric speciation through a founder effect is the predominant force driving evolution in vertebrates. The mouse lemurs of Madagascar are a system in which evolution has generated a large number of species over a relatively recent time frame. Here, we examine speciation patterns in a pair of sister species of mouse lemur, Microcebus murinus and M. griseorufus. These two species have ranges that are disparately proportioned in size, with M. murinus showing a much more extensive range that marginally overlaps that of M. griseorufus. Given that these two species are …

Evolutionary Cognitive Therapy Versus Standard Cognitive Therapy For Depression: A Protocol For A Blinded, Randomized, Superiority Clinical Trial, Cezar Giosan, Oana Cobeanu, Cristina Mogoase, Vlad Muresan, Loretta S. Malta, Katarzyna Wyka, Aurora Szentagotai

Publications and Research

Background: Depression is estimated to become the leading cause of disease burden globally by 2030. Despite existing efficacious treatments (both medical and psychotherapeutic), a large proportion of patients do not respond to therapy. Recent insights from evolutionary psychology suggest that, in addition to targeting the proximal causes of depression (for example, targeting dysfunctional beliefs by cognitive behavioral therapy), the distal or evolutionary causes (for example, inclusive fitness) should also be addressed. A randomized superiority trial is conducted to develop and test an evolutionary-driven cognitive therapy protocol for depression, and to compare its efficacy against standard cognitive therapy for depression.

Periodic Heat Shock Accelerated The Chondrogenic Differentiation Of Human Mesenchymal Stem Cells In Pellet Culture, Jing Chen, Chenghai Li, Sihong Wang

Publications and Research

Osteoarthritis (OA) is one of diseases that seriously affect elderly people's quality of life. Human mesenchymal stem cells (hMSCs) offer a potential promise for the joint repair in OA patients. However, chondrogenic differentiation from hMSCs in vitro takes a long time (∼6 weeks) and differentiated cells are still not as functionally mature as primary isolated chondrocytes, though chemical stimulations and mechanical loading have been intensively studied to enhance the hMSC differentiation. On the other hand, thermal stimulations of hMSC chondrogenesis have not been well explored. In this study, the direct effects of mild heat shock (HS) on the differentiation of …

Altering Murine Leukemia Virus Integration Through Disruption Of The Integrase And Bet Protein Family Interaction, Sriram Aiyer, G.V.T. Swapna, Nirav Malani, James M. Aramini, William M. Schneider, Matthew R. Plumb, Mustafa Ghanem, Ross C. Larue, Amit Sharma, Barbara Studamire, Mamuka Kvaratskhelia, Frederic D. Bushman, Gaetano T. Montelione, Monica J. Roth

Publications and Research

We report alterations to the murine leukemia virus (MLV) integrase (IN) protein that successfully result in decreasing its integration frequency at transcription start sites and CpG islands, thereby reducing the potential for insertional activation. The host bromo and extraterminal (BET) proteins Brd2, 3 and 4 interact with the MLV IN protein primarily through the BET protein ET domain. Using solution NMR, protein interaction studies, and next generation sequencing, we showthat the C-terminal tail peptide region ofMLV IN is important for the interaction with BET proteins and that disruption of this interaction through truncation mutations affects the global targeting profile of …

Synergism Between Airborne Singlet Oxygen And A Trisubstituted Olefin Sulfonate For The Inactivation Of Bacteria, Rajib Choudhury, Alexander Greer

Publications and Research

The reactivity of a trisubstituted alkene surfactant (8-methylnon-7-ene-1 sulfonate, 1) to airborne singlet oxygen in a solution containing E. coli was examined. Surfactant 1 was prepared by a Strecker-type reaction of 9-bromo-2-methylnon-2-ene with sodium sulfite. Submicellar concentrations of 1 were used that reacted with singlet oxygen by an “ene” reaction to yield two hydroperoxides (7-hydroperoxy-8-methylnon-8-ene-1 sulfonate and (E)-8-hydroperoxy-8-methylnon-6-ene-1 sulfonate) in a 4:1 ratio. Exchanging the H₂O solution for D₂O where the lifetime of solution-phase singlet oxygen increases by 20-fold led to an ∼2-fold increase in the yield of hydroperoxides pointing to surface activity …

We live in an era in which inequality is rampant. Media reports on inequality often gain little traction in a 24-hour news cycle dominated by the trivial. Activists work to address inequality in a myriad of ways, online and on the ground, but often lack connections to research or media that could further their cause. Key …

Laboratory Evaluation Of A Prospective Remediation Method For Pcb-Contaminated Paint, Erin K H Saitta, Michael J. Gittings, Christian Clausen, Jacqueline Quinn, Cherie L. Yestrebsky

Publications and Research

Background: Paint laden with polychlorinated biphenyls (PCBs) often acts as a point source for environmental contamination. It is advantageous to address contaminated paint before the PCBs transport to surrounding media; however, current disposal methods of painted material introduce a variety of complications. Previous work demonstrates that PCBs can be broken down at ambient temperatures and pressures through a degradation process involving magnesium metal and acidified ethanol. This report is an extension of that work by describing the development of a delivery system for said reaction in preparation for a field test. Two treatment options including the Activated Metal Treatment System …

Discovering Jewish Studies Collections In Academic Libraries: A Practical Guide, Izabella Taler

Publications and Research

The U.S. colleges and universities offering non-sectarian educational programs in Jewish Studies rely on the support of their academic libraries for research materials and library services. For college libraries which use Library of Congress Classification scheme, it is a common practice to integrate "studies" resources into their general library collections. Since Jewish Studies sources span a vast number of subjects within all major disciplines, shelving integration leads to the dispersion of all relevant sources and such dispersion in turn leads to a variety of problems for library professionals and library users. For collection development librarians the problems range from lack …

John Jay College's Research and Evaluation Center evaluated the effectiveness of the Cure Violence approach to violence reduction. Between April 2013 and February 2014, researchers began the project by visiting Cure Violence sites in New York City and Chicago, the home base for Cure Violence. The research team observed the program's operation and assessed the model's suitability for detailed evaluation. The report addresses the operations of the Cure Violence model and how it differs from other approaches for reducing gun violence. It reviews the evidence underlying these models and proposes an agenda for future evaluation research.

C. Elegans Cep-1/P53 And Bec-1 Are Involved In Dna Repair, Sandy Hoffman, Daniel Martin, Alicia Meléndez, Jill Bargonetti

Publications and Research

p53 is a transcription factor that regulates the response to cellular stress. Mammalian p53 functions as a tumor suppressor. The C. elegans p53, cep-1, regulates DNA-damage induced germline cell death by activating the transcription of egl-1 and ced-13. We used the C. elegans model to investigate how, in the whole animal, different forms of DNA damage can induce p53-dependent versus p53-independent cell death and DNA repair. DNA damage was induced by ultraviolet type C (UVC) radiation, or 10-decarbamoyl mitomycin C (DMC, an agent known to induce mammalian p53-independent cell death). Wild-type or cep-1 loss-of-function mutant animals were assayed for germline …

Disassembly Of The Cystovirus Φ6 Envelope By Montmorillonite Clay, Karin A. Block, Adrianna Trusiak, Al Katz, Paul Gottlieb, Alexandra Alimova, Hui Wei, Jorge Morales, William J. Rice, Jeffrey C. Steiner

Publications and Research

Prior studies of clay–virus interactions have focused on the stability and infectivity of nonenveloped viruses, yielding contradictory results. We hypothesize that the surface charge distribution of the clay and virus envelope dictates how the components react and affect aggregation, viral stability, and infectivity. The bacteriophage Cystoviridae species φ6 used in this study is a good model for enveloped pathogens. The interaction between φ6 and montmorillonite (MMT) clay (the primary component of bentonite) is explored by transmission electron microscopy. The analyses show that MMT–φ6 mixtures undergo heteroaggregation, forming structures in which virtually all the virions are either sequestered between MMT platelet …

Publications and Research

Extreme heat events (EHEs) are becoming more intense, more frequent and longer lasting in the 21st century. These events can disproportionately impact the health of low-income, minority, and urban populations. To better understand heat-related intervention strategies used by four U.S. cities, we conducted 73 semi-structured interviews with government and non-governmental organization leaders representing public health, general social services, emergency management, meteorology, and the environmental planning sectors in Detroit, MI; New York City, NY; Philadelphia, PA and Phoenix, AZ—cities selected for their diverse demographics, climates, and climate adaptation strategies. We identified activities these leaders used to reduce the harmful effects of …

Narratives Of Violence: The White Imagination And The Making Of Black Masculinity In “City Of God”, Jaime Alves

Publications and Research

The article explores the representation of young-black men in the 2002 film City of God. The film deploys “pathological scripts” of Black masculinity in Brazil as criminal and deviant. The controlling image of Black men’s bodies as a source of danger and impurity sustains Brazilian regime of racial domination, and the narratives of violence make explicit the ways in which the Brazilian nation is imagined though a racial underpinning. Blackness is consumed as an exotic commodity, yet is also understood as a threat to national harmony. The nation is, then, written and re-imagined as a racial paradise, but mostly by …

Cyclic Phosphonium Ionic Liquids, Sharon I. Lall-Ramnarine, Joshua A. Mukhlall, James F. Wishart, Robert R. Engel, Alicia R. Romeo, Masao Gohdo, Sharon Ramati, Marc B. Berman, Sophia N. Suarez

Publications and Research

Ionic liquids (ILs) incorporating cyclic phosphonium cations are a novel category of materials. We report here on the synthesis and characterization of four new cyclic phosphonium bis(trifluoromethylsulfonyl)amide ILs with aliphatic and aromatic pendant groups. In addition to the syntheses of these novel materials, we report on a comparison of their properties with their ammonium congeners. These exemplars are slightly less conductive and have slightly smaller self-diffusion coefficients than their cyclic ammonium congeners.

Peptide Detection Of Fungal Functional Amyloids In Infected Tissue, Melissa C. Garcia-Sherman, Nataliya Lysak, Alexandra Filonenko, Hazel Richards, Richard E. Sobonya, Stephen A. Klotz, Peter N. Lipke

Publications and Research

Many fungal cell adhesion proteins form functional amyloid patches on the surface of adhering cells. The Candida albicans Agglutinin-like sequence (Als) adhesins are exemplars for this phenomenon, and have amyloid forming sequences that are conserved between family members. The Als5p amyloid sequence mediates amyloid fibril formation and is critical for cell adhesion and biofilm formation, and is also present in the related adhesins Als1p and Als3p. We have developed a fluorescent peptide probe containing the conserved Als amyloid-forming sequence. This peptide bound specifically to yeast expressing Als5p, but not to cells lacking the adhesin. The probe bound to both yeast …

Sitapara, Vivek Patel, Mao Wang, Lokesh Sharma, Samir Gorasiya, Michelle Zur, Wenjun Wu, Jianhua Li, Huan Yang, Charles R. Ashby, Douglas Thomas, Haichao Wang, Lin L. Mantell

Publications and Research

Prolonged exposure to hyperoxia results in acute lung injury (ALI), accompanied by a significant elevation in the levels of proinflammatory cytokines and leukocyte infiltration in the lungs. However, the mechanisms underlying hyperoxia-induced proinflammatory ALI remain to be elucidated. In this study, we investigated the role of the proinflammatory cytokine high mobility group box protein 1 (HMGB1) in hyperoxic inflammatory lung injury, using an adult mouse model. The exposure of C57BL/6 mice to ≥99% O2 (hyperoxia) significantly increased the accumulation of HMGB1 in the bronchoalveolar lavage fluids (BALF) prior to the onset of severe inflammatory lung injury. In the airways of …

The Adaptive Remodeling Of Endothelial Glycocalyx In Response To Fluid Shear Stress, Ye Zeng, John M. Tarbell

Publications and Research

The endothelial glycocalyx is vital for mechanotransduction and endothelial barrier integrity. We previously demonstrated the early changes in glycocalyx organization during the initial 30 min of shear exposure. In the present study, we tested the hypothesis that long-term shear stress induces further remodeling of the glycocalyx resulting in a robust layer, and explored the responses of membrane rafts and the actin cytoskeleton. After exposure to shear stress for 24 h, the glycocalyx components heparan sulfate, chondroitin sulfate, glypican-1 and syndecan-1, were enhanced on the apical surface, with nearly uniform spatial distributions close to baseline levels that differed greatly from the …

Seasonal Mesophotic Coral Bleaching Of Stylophora Pistillata In The Northern Red Sea, Orit Nir, David F. Gruber, Eli Shemesh, Eliezra Glasser, Dan Tchernov

Publications and Research

Coral bleaching occurs when environmental stress induces breakdown of the coral-algae symbiosis and the host initiates algae expulsion. Two types of coral bleaching had been thoroughly discussed in the scientific literature; the first is primarily associated with mass coral bleaching events; the second is a seasonal loss of algae and/or pigments. Here, we describe a phenomenon that has been witnessed for repeated summers in the mesophotic zone (40–63 m) in the northern Red Sea: seasonal bleaching and recovery of several hermatypic coral species. In this study, we followed the recurring bleaching process of the common coral Stylophora pistillata. Bleaching occurred …
