Abstract: The invention provides for the expression and purification of a recombinant form of FABP (Fh15) exhibiting a similar suppressive effect on TLR-stimulation and inflammatory cytokine expression from macrophages than those previously demonstrated for the native molecule. Fh15 suppresses the expression of IL-1? and TNF? in murine macrophages and THP1 Blue CD14 cells. Additionally, Fh15 suppress the LPS-induced TLR4 stimulation. This effect was not impaired by a thermal denaturing process or blocked by the presence of anti-Fh12 antibodies. Fh15 also suppressed the stimulation of various TLRs in response to whole bacteria extracts so that Fh15 could be an excellent alternative for an anti-inflammatory drug in preclinical studies in the near future.

Abstract: A series of pharmaceutical metal complexes (pMCs) were produced and characterized using the mast cell stabilizer, cromolyn, and bioactive metal ions (Zn+2, Mg+2, and Ca+2). Three novel pMCs, Cromolyn-Zn, Cromolyn-Mg, and Cromolyn-Ca were formed through reactions under controlled temperature and pH conditions. TGA demonstrated that these metal complexes showed an enhanced thermal stability due to the strong coordination with the ligand, cromolyn. PXRD data indicates a high degree of crystallinity as well as a unique packing arrangement for each pMCs. SEM analysis showed materials with well-defined morphologies while EDS presented elemental evidence for the unique composition of each pMCs. The crystal structure for these materials was elucidated through SCXRD, and a variety of binding modes and packing motifs were found within each respective metal complex. Only 2D structures were achieved under the conditions studied.

Abstract: The invention proposes the photosensitized generation of nitric oxide (NO) from alanosine (3-(hydroxynitrosoamino)-D,L-alanine) by aluminum phthalocyanine tetrasulfonate (AlPcS4). While NO is obtained in nitrogen-saturated solutions, the invention proposes that both NO and peroxynitrite are produced in air-saturated solutions. Enhancement of NO production occurs in the presence of ubiquinone-0. The invention evidence that NO is produced by the photosensitized oxidation of alanosine. Both NO and peroxynitrite are detected during photoirradiation of AlPcS4 in the presence of 2-methyl-2-nitrosopropane (MNP) and hypoxanthine, but not in the absence of hypoxanthine, in air-saturated solutions, where HX is acting as sacrificial electron donor, thus promoting superoxide formation.

Abstract: The invention is a high-throughput voltage screening crystallographic device and methodology that uses multiple micro wells and electric circuits capable of assaying different crystallization condition for the same or different proteins of interest at the same of different voltages under a humidity and temperature controlled environment. The protein is solubilized in a lipid matrix similar to the lipid composition of the protein in the native environment to ensure stability of the protein during crystallization. The invention provides a system and method where the protein is transferred to a lipid matrix that holds a resting membrane potential, which reduces the degree of conformational freedom of the protein. The invention overcomes the majority of the difficulties associated with vapor diffusion techniques and essentially reconstitutes the protein in its native lipid environment under “cuasi” physiological conditions.

Abstract: The invention provides extended bisphosphonate-based metal complexes using benzene1,4-bis(bisphosphonic acid) (BBPA), an analog of benzene 1,4-dicarboxylic acid (BDC). Hydrothermal synthesis of BBPA with the bioactive metals Ca2+, Zn2+, and Mg2+ leads to four crystals phases, namely, BBPA-Ca forms I and II, BBPA-Zn form I, and BBPA-Mg form I. Out of the three structures, BBPA-Ca form II presents large channels (8 ?×12 ?), potentiating the use of this framework to load drugs. Cytotoxicity effects of BBPA was elucidated in a human breast cancer MDA-MB-231 and a normal osteoblast hFOB 1.19 cell lines. The half-maximal inhibitory concentration (IC50) for BBPA used to treat both cell lines were >200 ?M at 24, 48, and 72 h of treatment. The BBPA in the range of concentration employed (0-200 ?M) was not cytotoxic against these cell lines.

Abstract: A new passive control building arrangement is provided for improving the seismic response of structures. The proposed control arrangement was incorporated to a 1/20 scale model of a steel structure. The SAP2000 software program was used to develop an analytical model of the constructed scale model. After using a series of experimental data to calibrate the analytical model, valuable information of the dynamic properties of the arrangement was obtained. Different configurations with distinct parameters of the control arrangement were analyzed in the program to evaluate the variables that affect the dynamic properties of the model. It was determined that the geometric configuration of the arrangement and the spring stiffness value of a spring used in the arrangement affect considerably the dynamic properties. Simulated earthquake tests were performed in two proposed alternatives of the control arrangement to evaluate their effectiveness in improving the seismic response of the scale model.

Abstract: A simple optical layout for a grazing angle probe mount that allows coupling to a mid-infrared (MIR), laser-based spectrometer is provided. The assembly enables doing reflectance measurements at high incident angles. In the case of optically thin films and deposits on MIR reflective substrates, a double pass effect, accompanied by absorption by the chemicals or biological samples deposited in an Infrared Reflection-Absorption Infrared Spectroscopy (IRRAS) modality is achieved. The optical system includes a probe that allows the passage of MIR light through the same sampling area twice. Initially, the infrared beam produces a spot on the surface, and then the light is returned in back reflection to the sample surface producing a new little slightly larger spot onto the selfsame position.

Abstract: The enzyme telomerase is present at about 85% of human cancers that makes it not only an excellent target for cancer treatment but also an excellent marker for cancer detection. Using a single stranded DNA probe specific for telomerase binding and reverse transcription tethered to an interdigital gold electrode array surface, the chromosome protection provided by the telomerase was replicated and followed by Electrochemical Impedance Spectroscopy as an unlabeled biosensor. Using a custom system, which is simple and affordable, the impedance measurements were taken while incubating at 37° C. and promoting the probe elongation. This resulted in up to 14-fold increase in the charge transfer resistance when testing a telomerase-positive nuclear extract from Jurkat cells compared to the heat-inactivated telomerase-negative nuclear extract.

Abstract: Plakortinic acids A (2) and B (3), two polyketide endoperoxides having an unprecedented bicyclo[4.2.0]octene unit, were isolated as minor constituents from the sponge-sponge symbiotic association Plakortis halichondrioides-Xestospongia deweerdtae from Puerto Rico, along with the known epiplakinic acid F (1). The molecular structures of 2 and 3 were determined mainly on the basis of NMR spectroscopy. Due to the structural similarities, 2 and 3 are thought to be biosynthetically related to 1. Biological screening for cytotoxic activity against two human tumor cell lines revealed that these novel metabolites are very active at low to sub-micro molar concentration.
