Magnetic resonance imaging of disseminated bone marrow disease in patients treated for malignancy.

Skeletal radiology

Hanna SL, Fletcher BD, Fairclough DL, Jenkins JH, Le AH.
PMID: 2020867
Skeletal Radiol. 1991;20(2):79-84. doi: 10.1007/BF00193815.

Magnetic resonance imaging (MRI) is a sensitive method for the diagnosis of bone marrow abnormalities, but its usefulness in detecting active disseminated cancer in this tissue in treated patients has not been determined. We therefore examined 14 children who...

Muscle edema in musculoskeletal tumors: MR imaging characteristics and clinical significance.

Journal of magnetic resonance imaging : JMRI

Hanna SL, Fletcher BD, Parham DM, Bugg MF.
PMID: 1790366
J Magn Reson Imaging. 1991 Jul-Aug;1(4):441-9. doi: 10.1002/jmri.1880010408.

To determine the frequency and clinical significance of tumor-associated muscle edema, magnetic resonance (MR) imaging findings in 46 consecutive patients with benign or malignant musculoskeletal lesions were reviewed. Increased muscle signal intensity on T2-weighted, STIR (short-inversion-time inversion-recovery), and gadopentetate...

Subtraction technique for contrast-enhanced MR images of musculoskeletal tumors.

Magnetic resonance imaging

Hanna SL, Langston JW, Gronemeyer SA, Fletcher BD.
PMID: 2195271
Magn Reson Imaging. 1990;8(3):213-5. doi: 10.1016/0730-725x(90)90091-f.

Vascularized malignant tissue, fat and hemorrhage may have similar intensities on Gd-DTPA-enhanced, T1-weighted MRI performed to evaluate musculoskeletal tumors. We describe a simple, rapid post-processing subtraction technique which resulted in improved definition of these tissues in 33 of 42...

Variability of critical epitopes within HIV-1 heptad repeat domains for selected entry inhibitors in HIV-infected populations worldwide [corrected].

AIDS (London, England)

BACKGROUND: Two of the fusion inhibitors T-20 and 5-helix polypeptide have been shown to be potent inhibitors of cell-to-cell fusion and are currently under investigation as therapy for HIV-1.OBJECTIVES: To examine variability of HIV-1 gp41 heptads repeat regions (HR1...

Genome-wide RNAi screen identifies broadly-acting host factors that inhibit arbovirus infection.

PLoS pathogens

Yasunaga A, Hanna SL, Li J, Cho H, Rose PP, Spiridigliozzi A, Gold B, Diamond MS, Cherry S.
PMID: 24550726
PLoS Pathog. 2014 Feb 13;10(2):e1003914. doi: 10.1371/journal.ppat.1003914. eCollection 2014 Feb.

Vector-borne viruses are an important class of emerging and re-emerging pathogens; thus, an improved understanding of the cellular factors that modulate infection in their respective vertebrate and insect hosts may aid control efforts. In particular, cell-intrinsic antiviral pathways restrict...

The neutralizing antibody response against West Nile virus in naturally infected horses.

Virology

Sánchez MD, Pierson TC, Degrace MM, Mattei LM, Hanna SL, Del Piero F, Doms RW.
PMID: 17055550
Virology. 2007 Mar 15;359(2):336-48. doi: 10.1016/j.virol.2006.08.047. Epub 2006 Oct 20.

A major neutralizing epitope (here referred to as the T332 epitope) located on the lateral surface of domain III (DIII) of the West Nile virus (WNV) envelope protein has been identified based on the analysis of murine monoclonal antibodies....

Genome-wide RNAi screen identifies SEC61A and VCP as conserved regulators of Sindbis virus entry.

Cell reports

Panda D, Rose PP, Hanna SL, Gold B, Hopkins KC, Lyde RB, Marks MS, Cherry S.
PMID: 24332855
Cell Rep. 2013 Dec 26;5(6):1737-48. doi: 10.1016/j.celrep.2013.11.028. Epub 2013 Dec 12.

Alphaviruses are a large class of insect-borne human pathogens and little is known about the host-factor requirements for infection. To identify such factors, we performed a genome-wide RNAi screen using model Drosophila cells and validated 94 genes that impacted...

Analysis of the interaction of Ebola virus glycoprotein with DC-SIGN (dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin) and its homologue DC-SIGNR.

The Journal of infectious diseases

Marzi A, Möller P, Hanna SL, Harrer T, Eisemann J, Steinkasserer A, Becker S, Baribaud F, Pöhlmann S.
PMID: 17940955
J Infect Dis. 2007 Nov 15;196:S237-46. doi: 10.1086/520607.

BACKGROUND: The lectin DC-SIGN (dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin) augments Ebola virus (EBOV) infection. However, it its unclear whether DC-SIGN promotes only EBOV attachment (attachment factor function, nonessential) or actively facilitates EBOV entry (receptor function, essential).METHODS: We...

Stabilization of an Unprecedented Hexanuclear Secondary Building Unit in a Thorium-Based Metal-Organic Framework.
