Mitochondrial Complex I: A PET Study in Comparison with 18 F-BMS-747158-02 in Rat Brain (2014)

We developed novel PET probes, 2-tert-butyl-4-chloro-5-{6-[2-(218F-fluoroethoxy)-ethoxy]-pyridin-3-ylmethoxy}-2H-pyridazin-3-one (18F-BCPP-EF) and 2-tert-butyl-4-chloro-5-[6-(4-18F-fluorobutoxy)pyridin-3-ylmethoxy]-2H-pyridazin-3-one (18F-BCPP-BF), for quantitative imaging of mitochondrial complex I (MC-I) activity in the brain and preliminarily evaluated their properties in comparison with 18FBMS-747158-02 (18F-BMS). Methods: The affinity of 18F-BCPPEF, 18 F-BCPP-BF, and 18 F-BMS to MC-I was analyzed using in vitro binding assays with 3 H-dihydrorotenone and bovine cardiomyocyte submitochondrial particles. 18 F-BCPP-EF, 18 F-BCPP-BF, or 18 F-BMS was intravenously injected into rats, and the uptake (standardized uptake value) in each organ was determined by dissection method. The effects of rotenone, a specific MC-I inhibitor, on the uptake of each probe were assessed by whole-body PET imaging in rats. Ischemic brain model rats were imaged using 18 FBCPP-EF. Results: The rank order of affinity to MC-I was 18 FBCPP-BF . 18 F-BMS . 18 F-BCPP-EF. The uptake of 18 F-BCPP-EF and 18 F-BMS was high in the heart, intermediate in brain, and low in muscle and bone 60 min after the injection. 18 F-BCPP-BF provided increasing bone uptake with time after the injection. The uptake of 18 F-BCPP-EF and 18 F-BMS into the brain and heart was significantly decreased by preadministration of rotenone; however, the reduction degree of 18F-BCPP-EF was more pronounced than that of 18FBMS. Rotenone did not affect 18F-BCPP-BF uptake in either the brain or the heart. 18F-BCPP-EF imaged the cortical ischemic neuronal damage without any disturbance by microglial activation even on day 7 when 18F-FDG showed high uptake in the damaged area. Conclusion: The present study demonstrated that 18F-BCPP-EF could be a potential PET probe for quantitative imaging of MC-I activity and its ischemic damage in the living brain with PET.
Nasal Contribution to Exhaled Nitric Oxide at Rest and During Breathholding in Humans (1996)

We characterized the nasal contribution to exhaled nitric oxide (NO) at rest and during breathholding in humans. Exhaled NO was greater during nose breathing (141 +/- 17 nl/min/M2, mean +/- SEM) compared with mouth breathing (68 +/- 6 nl/min/M2, n = 8, p < 0.001). After voluntary closure of the soft palate (VCSP) to eliminate nasal NO, exhaled NO from the mouth decreased further (30 +/- 4 nl/min/M2, p < 0.001). Release of NO into nasal passages during VCSP (217 +/- 19 nl/min/M2) was greater than exhaled NO during nasal breathing (141 +/- 17 nl/min/m2, p < 0.001), suggesting that nasal NO is taken up by the respiratory tract. During mouth breathing or nose breathing, NO concentrations sampled with a bronchoscope were higher in the nasopharynx than at the epiglottis or in the trachea in five subjects. Increased peak exhaled NO after a breathhold (33 +/- 7 ppb) was reduced (10 +/- 4 ppb, p < 0.001) after balloon occlusion of the nasopharynx. NO concentration during breathholding increased to a greater extent in the nasopharynx than in the pharynx or trachea. We conclude that the majority of exhaled NO at rest and during a breathhold originates in the nasopharynx.
Coupling of FRET and Photoinduced Electron Transfer in Regioregular Silylene-Spaced Energy Donor–Acceptor−Electron Donor Copolymers (2008)

Two new silylene-spaced copolymers containing three kinds of different chromophores in regioregular manner were synthesized by rhodium-catalyzed hydrosilylation of a bisalkyne with a bis-silyl hydride. The photophysical and electrochemical properties of these polymers and the corresponding monomeric models were investigated. Time-resolved fluorescence spectroscopy has been employed for detailed kinetic analyses. The chromophores in these polymers have been shown to exhibit light harvesting to collect light energy, energy transfer, and efficient charge separation. The overall efficiencies involving both FRET and PET in these silylene-spaced vinylarene copolymers can be up to 96%.
High Pressure Diels−Alder Approach to Hydroxy-Substituted 6a-Cyano-tetrahydro-6H-benzo[c]chromen-6-ones: A Route to Δ6-Cis-Cannabidiol (2009)

Diels-Alder cycloaddition reactions of 3-cyanocoumarin, hydroxy-substituted 3-cyanocoumarins and mesyl-substituted 3-cyano-coumarins with methyl-1,3-butadienes carried out under high pressure (11 kbar) are reported. Activation by high pressure allows these reactions to proceed satisfactorily under mild conditions to produce 6a-cyano-hydroxy- and 6a-cyano-mesyl-tetrahydro-6H-benzo[c]chromen-6-ones in moderate to excellent yield. The synthesis of cis-1-hydroxy-9-methyl-3-pentyl-6a,7,10,10a-tetrahydro-benzo[c]chromen-6-one as precursor of Delta(6)-3,4-cis-cannabidiol (Delta(6)-cis-CBD) and Delta(8)-cis-tetrahydrocannabinol (Delta(8)-cis-THC) is outlined.
Growth and Renewal in the United States: Retooling America's Economic Engine* (2011)

New research by the McKinsey Global Institute (MGI) examines the growth challenge facing the United States and explores how U.S. business and government can contribute to the economy's renewal by reinvigorating their drive toward higher productivity. As baby boomers retire and the female participation rate plateaus, the U.S. economy will receive significantly less lift from increases in the labor force and will have to rely increasingly on productivity gains to fuel growth. The report finds that the United States needs a 34% acceleration in productivity growth if it is to match the GDP growth rates of the past 20 years—and that this is possible. Three‐quarters of the necessary productivity growth acceleration can come from the efforts of private‐sector companies operating within the current regulatory and business environment. Even the best‐performing companies and sectors still have headroom to boost productivity by emulating the best practice of others and tapping into new innovations, and coming up with new innovations of their own. The remaining one‐quarter—and more—can come from government and business working together to address barriers that now limit growth. MGI lays out a seven‐point agenda for action to spur productivity.
A monoclonal antibody specific for mouse dendritic cells. (1982)

Dendritic cells (DC) are a small subpopulation of lymphoid cells with distinctive cytologic features, surface properties, and functions. This report describes the DC-specific antibody (Ab) secreted by clone 33DI. Rat spleen cells immune to mouse DC were fused to the P3U myeloma. Hybrid culture supernatants were screened simultaneously against DC, a macrophage (M phi) cell line, and mitogen-stimulated lymphoblasts. 33DI Ab specifically killed 80-90% of DC from spleen and lymph node, but no other leukocytes, including Ia+ and Ia- M phi (Ia, I-region-associated antigen,). Quantitative binding studies with 5H-labeled 33D1 Ab showed that DC had an average of 14,000 binding sites per cell. Binding to DC was inhibited with Fab fragment of 33D1 Ab but not with a panel of other monoclonal antibodies, including anti-Ia Ab. Adherence and flotation procedures that enriched for DC enriched for 3H-labeled 33D1 Ab binding in parallel. 33D1 antigen was not detectable on: M phi from spleen, peritoneal cavity, and blood; three M phi cell lines; lymphocytes; granulocytes; platelets; and erythroid cells. DC continued to express the 33D1 antigen after 4 days in culture, whereas M phi and lymphocytes did not acquire it. Quantitative and autoradiographic studies confirmed that spleen and lymph node suspensions contain less than 1% DC. We conclude that 33D1 Ab detects a stable and specific DC antigen and can be used to monitor DC content in complex lymphoid mixtures.
Novel method for clearing red blood cell debris from BacT/ALERT® blood culture medium for improved microscopic and antimycobacterial drug susceptibility test results (2007)

Even though automation in mycobacterial culture has immensely improved the detection of organisms, identification of species and antimycobacterial susceptibility testing from blood culture bottles remain cumbersome and error-prone due to the presence of intact red blood cells (RBCs). The removal or lysis of these RBCs and excessive protein from the blood components could theoretically help improve this process. The present study reports an effective method that uses ammonium chloride (NH(4)Cl) and Triton X-100 to lyse the RBCs in blood culture medium. The method was optimized by preparing various concentrations of NH(4)Cl and Triton X-100, and incubation conditions, leading to eight protocols. The lysis protocol with a concentration of 150 mM of NH(4)Cl, 0.5% Triton X-100, and 1% potassium bicarbonate, pH 7.0, and incubation at 37 degrees C for 15 min was found to be optimal. This method not only made the culture medium clear, the protein concentration decreased from 753.5+/-39.4 to 53.2+/-4.2 mg/mL in the M. tuberculosis-spiked culture medium and in the blood culture medium inoculated with the blood from tuberculosis patients. The method had no adverse effect on mycobacteria, and no depletion of M. tuberculosis colony-forming units was found. The lysate could be used for antimycobacterial susceptibility testing with no difficulty in setting the mycobacterial concentration of inoculum to 0.5 McFarland standards. Furthermore, this method had the added advantage in the microscopy and molecular methods for the speciation of Mycobacterium sp.
Epitaxial growth of AlxGa1−xN on Si(111) via a ZrB2(0001) buffer layer (2004)

Epitaxial growth of an Al0.2Ga0.8N(0001) film by metalorganic chemical vapor deposition (MOCVD) at 1050 °C on a Si(111) substrate via a ZrB2(0001) buffer layer has been accomplished free of unintentional Si doping. The in-plane lattice mismatch between Al0.2Ga0.8N(0001) and ZrB2(0001) is only 0.3% and good epitaxial relation is established with [112_0]AlGaN//[112_0]ZrB2//[1_10]Si. The cathodoluminescence (CL) spectrum of the Al0.2Ga0.8N shows a band-edge emission at 3.87 eV with full width at half maximum (FWHM) of 40 meV. Both the intensity and FWHM of the CL emission are comparable to those from a high-quality undoped Al0.2Ga0.8N film grown by MOCVD on sapphire. The close lattice match and the reflective nature of the ZrB2(0001) buffer layer are both attributes accountable for the optical quality of the Al0.2Ga0.8N grown on Si(111).
Additive Protection of the Ischemic Heart Ex Vivo by Combined Treatment With δ-Protein Kinase C Inhibitor and ε-Protein Kinase C Activator (2003)

delta-PKC inhibitor prevents reperfusion injury, and epsilon-PKC activator mimics ischemic preconditioning. Furthermore, treatment with both peptides confers additive cardioprotective effects. Therefore, these peptides mediate cardioprotection by regulating ischemia/reperfusion damage at distinct time points.
Ordered Mesoporous Materials for Bioadsorption and Biocatalysis (2005)

The encapsulation of enzymes and other proteins into inorganic host materials has attracted considerable attention over the past few years. This research has demonstrated that biomolecules immobilized in inorganic matrixes retain their functional characteristics to a large extent. These new materials are of interest for applications as (optically based) biosensors and biocatalysts. We review the growing field of amino acids, vitamins, enzymes, and whole cells adsorbed (immobilized) onto ordered mesoporous silica and carbon molecular sieves. Strategies for the preparation of mesoporous supports and the essential properties of the resulting materials with respect to the envisaged applications are presented. Basic effects of the nature of the adsorption and various aspects of the application of these materials as biosensors, bicatalysts, and for drug release are discussed. Outlook of potential applications and further challenges are also provided.
Acoustic channel drop tunneling in a phononic crystal (2005)

We study both theoretically and experimentally the possibility of resonant tunneling of acoustic waves between two parallel guides created in a phononic crystal composed of steel cylinders in water. In the absolute band gap of the phononic crystal, ranging from 250to325kHz, a full transmission band exists for propagation inside a straight waveguide. We show that the transfer of a particular wavelength can occur between two parallel waveguides coupled together through an appropriate coupling structure. The latter is composed of isolated cavities interacting with stubs located at the sides of the waveguides.
Prostate Cancer Susceptibility Locus on Chromosome 1q: a Confirmatory Study (1997)

Our data confirm that chromosome 1q24-25 is likely to contain a prostate cancer susceptibility gene. Future efforts at positional cloning of the HPC1 gene should focus on families who meet the proposed clinical criteria for hereditary prostate cancer.
The B7 Homologues and their Receptors in Hematologic Malignancies (2012)

The B7 homologues and their receptors regulate both peripheral tolerance and adaptive immunity. This field is rapidly evolving as new ligands and receptors are being identified. Much of the work supporting their role in the regulation of host anti-tumor immunity has been derived from experimental models and clinical trials in solid malignancies. However, a growing body of evidence demonstrates that the B7-H family has important immunologic and non-immunologic functions in a variety of hematologic malignancies. Herein, we will review recent evidence that supports the therapeutic targeting of the B7 homologues in hematologic malignancies.

A Phase I Pharmacokinetic and Pharmacodynamic Study of Dalotuzumab (MK-0646), an Anti-Insulin-like Growth Factor-1 Receptor Monoclonal Antibody, in Patients with Advanced Solid Tumors (2011)

Dalotuzumab was generally well-tolerated, exhibited dose-proportional PK, inhibited IGF-1R pathway signaling and cell proliferation in treated tumors, and showed clinical activity. The low clearance rate and long terminal half-life support more extended dosing intervals.
FISH with Padlock Probes Can Efficiently Reveal the Genomic Position of Low or Single-Copy DNA Sequences (2017)

A padlock probe is a circularized oligonucleotide containing complementary sequences of target regions. Padlock probes combined with rolling-circle amplification enable fluorescence in situ hybridization (FISH) to reproducibly detect the genomic position of low or single-copy DNA sequences. The FISH with padlock probes revealed that a plant gene cluster of tandemly arrayed three paralogues responsible for photosynthesis rapidly moved from the interior subnuclear region to the peripheral subnuclear region in response to light. Using a pair of peptide nucleic acids as a double-strand opener for the target region, the efficiency of FISH with padlock probes at the detection of a single-copy genomic region was much improved. FISH with padlock probes will give us reliable data of dynamics, arrangement and position of a specific single locus in both the nucleus and the condensed chromosomes.
Low‐level laser therapy stimulates bone–implant interaction: an experimental study in rabbits (2004)

The aim of the present study was to investigate the effect of low-level laser therapy (LLLT) with a gallium-aluminium-arsenide (GaAlAs) diode laser device on titanium implant healing and attachment in bone. This study was performed as an animal trial of 8 weeks duration with a blinded, placebo-controlled design. Two coin-shaped titanium implants with a diameter of 6.25 mm and a height of 1.95 mm were implanted into cortical bone in each proximal tibia of twelve New Zealand white female rabbits (n=48). The animals were randomly divided into irradiated and control groups. The LLLT was used immediately after surgery and carried out daily for 10 consecutive days. The animals were killed after 8 weeks of healing. The mechanical strength of the attachment between the bone and 44 titanium implants was evaluated using a tensile pullout test. Histomorphometrical analysis of the four implants left in place from four rabbits was then performed. Energy-dispersive X-ray microanalysis was applied for analyses of calcium and phosphorus on the implant test surface after the tensile test. The mean tensile forces, measured in Newton, of the irradiated implants and controls were 14.35 (SD+/-4.98) and 10.27 (SD+/-4.38), respectively, suggesting a gain in functional attachment at 8 weeks following LLLT (P=0.013). The histomorphometrical evaluation suggested that the irradiated group had more bone-to-implant contact than the controls. The weight percentages of calcium and phosphorus were significantly higher in the irradiated group when compared to the controls (P=0.037) and (P=0.034), respectively, suggesting that bone maturation processed faster in irradiated bone. These findings suggest that LLLT might have a favourable effect on healing and attachment of titanium implants.
Xenogenization of a mouse lung carcinoma (3LL) by transfection with an allogeneic class I major histocompatibility complex gene (H-2Ld). (1987)

We investigated the tumorigenicity and immunogenicity of tumor cells transfected with an allogeneic class I major histocompatibility complex gene. A single clone (3LL/3) from a Lewis lung carcinoma in the C57BL/6 strain (H-2b) was cotransfected with a BALB/c genomic clone containing an H-2Ld gene and a bacterial neo gene conferring resistance to G418. Three Ld-positive, three Ld-negative, and two Neor clones were selected by means of a 125I-protein A binding assay using an anti-H-2Ld monoclonal antibody. The antigenic expression of the H-2Ld gene products was only 20-40% on the Ld-positive clones compared with Meth-A tumor cells of BALB/c mice. The 50% lethal tumor dose of these clones in C57BL/6 mice was 5.6 X 10(6) in the Ld-positive clones, but only 1.3 X 10(5) in the 3LL/3 parent clone, 1.2 X 10(5) in the Neor clones, and 2.2 X 10(5) in the Ld-negative clones. The tumorigenicity of the Ld-positive clones was, therefore, reduced to less than 1/40 of that of the parent tumor cells. The decreased tumorigenicity of the Ld-positive clones was abrogated in mice irradiated with 600 rads. After inoculation and spontaneous regression of the viable Ld-positive clone cells, the mice acquired transplantation resistance against the challenge of a parental 3LL/3 tumor. However, the immunogenicity variation between Ld-positive, Ld-negative, Neor, and 3LL/3 parent clones showed no statistical difference. These results indicate that tumor cells transfected with an allogeneic class I H-2 gene can express an H-2 foreign antigen, can regress in syngeneic hosts, and can induce antitumor transplantation resistance against the original tumors, although they are not able to enhance their immunogenicity.
STAT3-Activating Cytokines: A Therapeutic Opportunity for Inflammatory Bowel Disease? (2015)

The gastrointestinal tract is lined by a single layer of epithelial cells that secrete mucus toward the lumen, which collectively separates the immune sentinels in the underlying lamina propria from the intestinal microflora to prevent aberrant immune responses. Inflammatory bowel disease (IBD) describes a group of autoimmune diseases that arise from defects in epithelial barrier function and, as a consequence, aberrant production of inflammatory cytokines. Among these, interleukin (IL)-6, IL-11, and IL-22 are elevated in human IBD patients and corresponding mouse models and, through activation of the JAK/STAT3 pathway, can both propagate and ameliorate disease. In particular, cytokine-mediated activation of STAT3 in the epithelial lining cells affords cellular protection, survival, and proliferation, thereby affording therapeutic opportunities for the prevention and treatment of colitis. In this review, we focus on recent insights gained from therapeutic modulation of the activities of IL-6, IL-11, and IL-22 in models of IBD and advocate a cautionary approach with these cytokines to minimize their tumor-promoting activities on neoplastic epithelium.
Effects of vitamin E on immune function of dairy cows (1995)

The effect of vitamin E supplementation on the immune function of dairy cows was studied. Twelve cows were assigned to 1 of the 2 experimental groups: control (no vitamin E supplementation), and vitamin E-supplemented. Supplementation of vitamin E started 4 weeks before and continued up to 8 weeks after parturition and included oral supplementation of vitamin E at the rate of 3,000 IU/cow/d. In addition, the same group of cows received 1 injection of vitamin E (5,000 IU), 1 week prior to the expected date of parturition. Data indicated that blood neutrophils isolated from control cows produced twofold less (P < 0.05) superoxide anion after parturition, compared with the corresponding value before parturition. Furthermore, blood macrophages isolated from control cows produced 15 and 35% (P < 0.05) less interleukin 1 (IL-1) and major histocompatibility (MHC) class-II antigens, respectively, after parturition, compared with the corresponding values before parturition. These data, collectively, indicate that functions of blood macrophages and neutrophils are depressed during the early postpartum period in control cows. In contrast, there were no differences in superoxide anion production by blood neutrophils, or in IL-1 production, and MHC class-II antigen expression by blood macrophages before and after parturition in cows supplemented with vitamin E. There were no differences in lymphocyte proliferation, or IL-1 production and MHC class-II antigen expression by mammary macrophages when control and vitamin E-supplemented cows were compared. We conclude that vitamin E prevented suppression of blood neutrophil and macrophage function during the early postpatum period.
