A retrospective review of the clinical records of 54 patients with systemic lupus erythematosus (SLE) and documented tuberculosis (TB) infection seen at the University of Santo Tomas Hospital was accomplished. There were 53 women and one man, with a mean age of 32.2 +/- 10 years and a total of 57 TB occurrences. Pulmonary involvement was recorded in 42(More)
High molecular weight (MW) polymers have shown promise in terms of improving the properties and the efficacy of low MW therapeutics. However, new systems that are highly biocompatible, are biodegradable, have well-defined MW, and have multiple functional groups for drug attachment are still needed. The biological evaluation of a library of eight polyester(More)
The synthesis of a variety of core functionalized PEGylated polyester dendrimers and their in vitro and in vivo properties are described in this report. These water-soluble dendrimers have been designed to carry eight functional groups on their dendritic core for a variety of biological applications such as drug delivery and in vivo imaging as well as eight(More)
Rigid-rod dendronized linear polymers consisting of a poly(4-hydroxystyrene) backbone and fourth-generation polyester dendrons were evaluated in vitro and in vivo to determine their suitability as drug delivery vectors. Cytotoxicity assays indicated that the polymers were well tolerated by cells in vitro. Biodistribution studies of the polymers in both(More)
We evaluated gene transfer using PEGylated bioresponsive nanolipid particles (NLPs) containing plasmid DNA administered by convection-enhanced delivery (CED) into orthotopically implanted U87-MG tumors in rat brain. We hypothesized that attachment of the human immunodeficiency virus trans-acting transcriptional activator peptide (TATp) to pH-sensitive,(More)
The antitumor effect of doxorubicin (DOX) conjugated to a biodegradable dendrimer was evaluated in mice bearing C-26 colon carcinomas. An asymmetric biodegradable polyester dendrimer containing 8-10 wt % DOX was prepared. The design of the dendrimer carrier optimized blood circulation time through size and molecular architecture, drug loading through(More)
Matrix attachment therapy (MAT) is an enzyme prodrug strategy that targets hyaluronan in the tumor extracellular matrix to deliver a prodrug converting enzyme near the tumor cells. A recombinant fusion protein containing the hyaluronan binding domain of TSG-6 (Link) and yeast cytosine deaminase (CD) with an N-terminal His(x6) tag was constructed to test MAT(More)
In CKD, phosphate retention arising from diminished GFR is a key early step in a pathologic cascade leading to hyperthyroidism, metabolic bone disease, vascular calcification, and cardiovascular mortality. Tenapanor, a minimally systemically available inhibitor of the intestinal sodium-hydrogen exchanger 3, is being evaluated in clinical trials for its(More)
We immunized mice with an attenuated (cold-adapted) influenza virus followed by an attenuated vaccinia virus (modified vaccinia virus Ankara), both expressing a CD8(+)-T-cell epitope derived from malaria sporozoites. This vaccination regimen elicited high levels of protection against malaria. This is the first time that the vaccine efficacy of a recombinant(More)
Muscarinic receptors mediate the postsynaptic excitatory effects of acetylcholine (ACh) on inspiratory neurons in the pre-Bötzinger complex (pre-BötC), the hypothesized site for respiratory rhythm generation. Because pharmacological tools for identifying the subtypes of the muscarinic receptors that underlie these effects are limited, we probed for mRNA for(More)
