Cloned dendritic cells can present exogenous antigens on both MHC class I and class II molecules (1997)

Pathways for presenting proteins from the extracellular fluids on MHC class I molecules have been described in macrophages. However, it is uncertain whether similar mechanisms exist in dendritic cells, because conventional preparations of these cells can be contaminated with macrophages. We addressed this issue by transducing granulocyte-macrophage CSF into bone marrow cultures followed by supertransfection with myc and raf oncogenes. These immortalized clones displayed dendritic morphology, and many expressed the dendritic cell-specific markers DEC-205 and 33D1 as well as high levels of MHC molecules and costimulatory molecules. Using these cloned dendritic cells, we found that exogenous OVA could be presented on both their MHC class I and class II molecules. This presentation was markedly enhanced when the Ag was particulate and internalized by phagocytosis. Presentation of particulate OVA on MHC class I molecules was insensitive to the weak base chloroquine, but was blocked by peptide aldehyde inhibitors of the proteasome, indicating that the class I-presented peptides were generated in the cytosol. Brefeldin A, which inhibits the exocytosis of newly synthesized proteins from the endoplasmic reticulum, also inhibited Ag presentation. These results establish that dendritic cells can present exogenous Ags on MHC class I molecules and appear to use a similar phagosome to cytosol pathway as macrophages. Therefore, dendritic cells are likely to play an important role in generating immune responses to tissue transplants and tumors in vivo. Furthermore, these findings provide an approach for targeting vaccine Ags into these cells to prime immune responses in vivo.

These findings indicate that BPS has a therapeutic effect on diabetic nephropathy in the OLETF rat, which suggests a potential application of this drug in the treatment of human diabetic nephropathy.
High-Dose Chemotherapy and Stem-Cell Rescue for Metastatic Germ-Cell Tumors (2007)

Testicular tumors are potentially curable by means of high-dose chemotherapy plus hematopoietic stem-cell rescue, even when this regimen is used as third-line or later therapy or in patients with platinum-refractory disease.
Rapid and Simple Approach for Identification of Mycobacterium tuberculosis Complex Isolates by PCR-Based Genomic Deletion Analysis (2002)

Although the virulences and host ranges differ among members of the Mycobacterium tuberculosis complex (TBC; M. tuberculosis, M. africanum, M. canettii, M. microti, M. bovis, and M. bovis BCG), commercially available molecular assays cannot differentiate these organisms because of the genetic identities of their 16S rRNA gene sequences. Comparative genomic analyses with the complete DNA sequence of M. tuberculosis H37Rv has provided information on regions of difference (RD 1 to RD 16) deleted in members of the TBC other than M. tuberculosis. To determine whether deletion analysis could accurately differentiate members of TBC, we used PCR to assess the presence or absence of specific regions of the genome in 88 well-characterized isolates of M. tuberculosis, M. africanum, M. microti, M. bovis, and M. bovis BCG. The identifications obtained by use of the specific deletion profiles correlated 100% with the original identifications for all TBC members except M. africanum, but further characterization resulted in profiles specific for all members. Although six RD regions were used in the analyses with the original 88 isolates, it was found that the use of RD 1, RD 9, and RD 10 was sufficient for initial screenings, followed by the use of RD 3, RD 5, and RD 11 if the results for any of the first three regions were negative. When 605 sequential clinical isolates were screened, 578 (96%) were identified as M. tuberculosis, 6 (1%) were identified as M. africanum, 8 (1%) were identified as M. bovis, and 13 (2%) were identified as M. bovis BCG. Since PCR-based assays can be implemented in most clinical mycobacteriology laboratories, this approach provides a rapid and simple means for the differentiation of members of TBC, especially M. bovis and M. tuberculosis, when it is important to distinguish between zoonotic sources (i.e., cattle and unpasteurized dairy products) and human sources of tuberculosis disease.
Reactivity of peptidyl‐tyrosine to hydroxylation and cross‐linking (2001)

Tyrosine residues of neuroendocrine peptides are frequently the targets of oxidation reactions, one of which involves hydroxylation to peptidyl-3, 4-dihydroxy-phenyl-L-alanine (DOPA). The reactivity in vitro of peptidyl-DOPA in two neuroendocrine peptides, a neurotensin fragment (pELYENK) and proctolin (RYLPT), was investigated using ultraviolet-visible scanning spectrophotometry and matrix-assisted laser desorption ionization mass spectrometry following oxidation by tyrosinase and periodate. The peptides form covalently coupled dimers and trimers, and their masses are consistent with the presence of diDOPA cross-links. Lysine does not appear to participate in multimer formation because it is efficiently recovered in fragmentation ladders using subtilisin. While multimer formation in the neurotensin-derived peptide can be blocked effectively by adding N-acetyl-DOPA-ethylester to the reaction medium, the DOPA ethylester couples itself four to five times to each peptide.
Replication of adeno-associated virus in cells irradiated with UV light at 254 nm (1989)

Irradiation of simian virus 40 (ori mutant)-transformed Chinese hamster embryo cells (OD4 line) with UV light induced a cellular capacity which supported a full cycle of helper-independent adeno-associated virus replication. Monochromatic UV light at 254 nm was about 1,000-fold more effective than UV light at 313 nm, indicating that cellular nucleic acid is the primary chromophore in the UV-induced process leading to permissiveness for adeno-associated virus replication. The UV irradiation and the infection could be separated for up to 12 h without substantial loss of permissiveness. During this time interval, the induction process was partly sensitive to cycloheximide, suggesting a requirement for de novo protein synthesis.
Acute Posterior Cranial Fossa Hemorrhage—Is Surgical Decompression Better than Expectant Medical Management? (2016)

SDC following PCFH was associated with a reduction in mortality compared to expectant MT with or without EVD insertion. A high-quality multicenter randomized control trial is required to evaluate the superiority of SDC for PCFH.
Latency to paroxetine‐induced anxiolysis in the rat is reduced by co‐administration of the 5‐HT1A receptor antagonist WAY100635 (2000)

We report here the use of rat high-light social interaction to model the temporal anxiolytic/antidepressant effects of SSRIs seen in the clinic. Compared to vehicle controls, 21, but not 14, days of paroxetine treatment (3 mg kg(-1), p.o., daily) produced a marked increase in rat social interaction (Vehicle=71.3+/-7.3 s; Paroxetine=116.7+/-14.7 s; P<0.01) with no concurrent effect on locomotor activity, consistent with anxiolysis. To assess whether concurrent 5-HT(1A) receptor blockade reduces the time to onset of anxiolysis seen with paroxetine alone (21 days), rats were implanted with osmotic minipumps to continuously infuse the 5-HT(1A) receptor antagonist WAY100635 (1 mg kg(-1) day(-1), s.c., 7 days) alone or in combination with paroxetine (3 mg kg(-1), p.o., daily, 7 days), prior to anxiety testing. Paroxetine (Veh/Par=61.9+/-7.9 s) or WAY100635 (WAY/Veh=71.6+/-4.7 s) alone, had no effect on social interaction time compared to vehicle treated controls (Veh/Veh=76.4+/-4.9 s), whilst coadministration of WAY100635 with paroxetine, produced a marked elevation in social interaction (WAY/Par=149.3+/-16.8 s; P<0.01) relative to all other groups with no concurrent change in locomotor activity. In contrast, acute administration of WAY100635 (0.03 mg kg(-1), s.c.) with paroxetine (3 mg kg(-1), p.o.) did not alter any behavioural measure, suggesting that the anxiolysis induced by the combination after 7 days is attributable to a CNS adaptive response. This data demonstrates that coadministration of a 5-HT(1A) receptor antagonist with paroxetine markedly reduces the latency to anxiolysis, in the rat. This study supports the use of the rat social interaction test to further delineate adaptive changes in the CNS responsible for the anxiolytic/antidepressant action of SSRIs seen in humans.

Targeted Deletion of the Sclerostin Gene in Mice Results in Increased Bone Formation and Bone Strength (2008)

SOST KO mice have a high bone mass phenotype characterized by marked increases in BMD, bone volume, bone formation, and bone strength. These results show that sclerostin is a key negative regulator of a powerful, evolutionarily conserved bone formation pathway that acts on both trabecular and cortical bone.
Egg White Ovalbumin Digestion Mimicking Physiological Conditions (2010)

Gastrointestinal digestion of ovalbumin (OVA) was simulated using an in vitro system in two steps, which mimicked digestion in the stomach and duodenum, to assess the effect of different gastric pHs, different concentrations of proteases, and the presence of surfactants, such as phosphatidylcholine (PC) and bile salts (BS). OVA was very resistant to pepsin action at an enzyme/substrate ratio that would resemble a physiological situation (1:20 w/w, 172 units/mg) at pH values equal or above 2. The presence of PC did not change the susceptibility of OVA to proteolysis with pepsin. Fluorescence experiments showed that OVA interacted with PC vesicles, particularly at acidic pH, but it is likely that the protein maintained a high degree of conformational stability, resisting pepsin action. The presence of BS at physiological concentrations considerably increased the proteolysis of OVA by a mixture of pancreatic enzymes. The addition of PC made OVA even more sensitive to proteolytic degradation, suggesting that OVA could associate with the surfactants under duodenal conditions, increasing its exposure to pancreatic proteinases. Immunoreactivity against IgE from sera of allergic patients was retained after in vitro gastric digestion, depending on the reactivity of the sera, but it decreased considerably after in vitro duodenal digestion.
Planar Fully depleted SOI technology: A powerful architecture for the 20nm node and beyond (2010)

Recent device developments and achievements have demonstrated that planar undoped channel Fully depleted SOI devices are becoming a serious alternative to Bulk technologies for 20nm node and below. We have proven this planar option to be easier to integrate than the non planar devices like FinFET. This paper gives an overview of the main advantages provided by this technology, as well as the key challenges that need to be addressed. Electrostatic integrity, drivability, within wafer variability and scalability are addressed through silicon data (down to 18nm gate length) and TCAD analyses. Solutions to the Multiple V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</sub> challenges and non logic devices (ESD, I/Os) are also reported.
Impact of composition on the performance of sodium linear alkylbenzenesulfonate (NaLAS) (1997)

Abstract Like other commercial surfactants, commercial linear alkylbenzenesulfonate is not a single compound but a mixture of components. This mixture comprises different carbonchain homologs, different phenyl isomers, and, in addition, the manufacturing co‐product, dialkyltetralin sulfonate. Current manufacturing technology makes it possible to easily vary the average carbon chainlength. On the other hand, the phenyl isomer distribution and dialkyltetralin sulfonate content can be changed only within a certain range. Each of these variations in composition affects performance. This study reports on the effect of commercial alkylbenzenesulfonate composition on surface tension, solubility, viscosity, foam stability, and detergency. The study shows that average carbon chainlength affects all performance properties. Phenyl isomer distribution and dialkyltetralin sulfonate content affect only solubility and viscosity.
Rationale for Antiangiogenic Cancer Therapy with Vaccination Using Epitope Peptides Derived from Human Vascular Endothelial Growth Factor Receptor 2 (2005)

Angiogenesis is a critical mechanism for tumor progression. Multiple studies have suggested that tumor growth can be suppressed if tumor angiogenesis can be inhibited using various types of antiangiogenic agents. Recent studies in mouse systems have shown that tumor angiogenesis can also be inhibited if cellular immune response could be induced against vascular endothelial growth factor receptor 2 (VEGFR2), which is one of the key factors in tumor angiogenesis. In this study, we examined the possibility of developing this novel immunotherapy in clinical setting. We first identified the epitope peptides of VEGFR2 and showed that stimulation using these peptides induces CTLs with potent cytotoxicity in the HLA class I-restricted fashion against not only peptide-pulsed target cells but also endothelial cells endogenously expressing VEGFR2. In A2/Kb transgenic mice that express alpha1 and alpha2 domains of human HLA-A*0201, vaccination using these epitope peptides in vivo was associated with significant suppression of the tumor growth and prolongation of the animal survival without fatal adverse effects. In antiangiogenesis assay, tumor-induced angiogenesis was significantly suppressed with the vaccination using these epitope peptides. Furthermore, CTLs specific to the epitope peptides were successfully induced in cancer patients, and the specificities of the CTLs were confirmed using functional and HLA-tetramer analysis. These results in vitro and in vivo strongly suggest that the epitope peptides derived from VEGFR2 could be used as the agents for antiangiogenic immunotherapy against cancer in clinical settings.

Efficient delivery of genome-editing proteins using bioreducible lipid nanoparticles (2016)

A central challenge to the development of protein-based therapeutics is the inefficiency of delivery of protein cargo across the mammalian cell membrane, including escape from endosomes. Here we report that combining bioreducible lipid nanoparticles with negatively supercharged Cre recombinase or anionic Cas9:single-guide (sg)RNA complexes drives the electrostatic assembly of nanoparticles that mediate potent protein delivery and genome editing. These bioreducible lipids efficiently deliver protein cargo into cells, facilitate the escape of protein from endosomes in response to the reductive intracellular environment, and direct protein to its intracellular target sites. The delivery of supercharged Cre protein and Cas9:sgRNA complexed with bioreducible lipids into cultured human cells enables gene recombination and genome editing with efficiencies greater than 70%. In addition, we demonstrate that these lipids are effective for functional protein delivery into mouse brain for gene recombination in vivo. Therefore, the integration of this bioreducible lipid platform with protein engineering has the potential to advance the therapeutic relevance of protein-based genome editing.
Properties of Escherichia coli mutants altered in calcium/proton antiport activity (1979)

Mutants sensitive to growth inhibition by CaCl2 were found to have alterations in calcium uptake in everted membrane vesicles. These mutations map at different loci on the Escherichia coli chromosomes. A mutation at the calA locus results in vesicles which have two- to threefold higher levels of uptake activity than vesicles from wild-type cells. The calA mutation is phenotypically expressed as increased sensitivity to CaCl2 in a strain also harboring a mutation in the corA locus, which is involved in Mg2+ transport. The calA locus maps very close to purA and cycA at about min 97. The calB mutation results both in sensitivity to CaCl2 at pH 5.6 and in vesicles with diminished calcium transport capability. The CalB phenotype is also expressed only in a corA genetic background; the calB locus appears to map very near, yet separately from, the calA locus. When the cor+ allele is present, calA and calB mutations still result in a defect in calcium transport in vesicles. In addition, both calC and calD mutations result in vesicles with impaired calcium transport activity. calC is cotransducible with kdp and nagA, whereas calD is cotransducible with proC.

Tumor inhibition by titanocene complexes. Activity against B16 melanoma and colon 38 carcinoma. (1987)

In the present study, the antitumor activity of some titanocene derivatives (C5H5)2TiX2 (I, X = Cl; II, X = Br; III, X = cis-OOCCH = CHCOOH; IV, X = p-SC6H4NH3+Cl-) was investigated against B16 melanoma and colon 38 carcinoma. Both tumors grew subcutaneously as solid tumors in mice. Substances were applied intraperitoneally either as single, triple or 5-fold injections. Against both tumors, satisfactory results were observed for the chloro, bromo and aminothiophenolato derivatives I, II and IV, resp. They reduced tumor growth by 60-80% to 40-20% of control values. These effects underline the antitumor potency of titanocene complexes and show that titanocene dihalides as well as titanocene derivatives containing hydrophilic ligands X are able to inhibit the growth of various solid experimental tumors.
High efficiency of HIV-1 genomic RNA packaging and heterozygote formation revealed by single virion analysis (2009)

A long-standing question in retrovirus biology is how RNA genomes are distributed among virions. In the studies presented in this report, we addressed this issue by directly examining HIV-1 RNAs in virions using a modified HIV-1 genome that contained recognition sites for BglG, an antitermination protein in the Escherichia coli bgl operon, which was coexpressed with a fragment of BglG RNA binding protein fused to a fluorescent protein. Our results demonstrate that the majority of virions (>90%) contain viral RNAs. We also coexpressed HIV-1 genomes containing binding sites for BglG or the bacteriophage MS2 coat protein along with 2 fluorescent protein-tagged RNA binding proteins. This method allows simultaneously labeling and discrimination of 2 different RNAs at single-RNA-detection sensitivity. Using this strategy, we obtained physical evidence that virions contain RNAs derived from different parental viruses (heterozygous virion) at ratios expected from a random distribution, and we found that this ratio can be altered by changing the dimerization sequences. Our studies of heterozygous virions also support a generally accepted but unproven assumption that most particles contain 1 dimer. This study provides answers to long-standing questions in HIV-1 biology and illustrates the power and sensitivity of the 2-RNA labeling method, which can also be adapted to analyze various issues of RNA biogenesis including the detection of different RNAs in live cell imaging.
A new Co(ii)-metalloviologen-based electrochromic material integrated in thin multilayer films (2005)

A metallosupramolecular coordination polyelectrolyte prepared by the reaction of cobalt(II) with a novel bisterpyridine ligand has been assembled as the active component in electrochromic films by sequential deposition using electrostatic layer-by-layer self-assembly.
Synergistic effects of the fenretinide (4-HPR) and anti-CD20 monoclonal antibodies on apoptosis induction of malignant human B cells. (2001)

Retinoids have been shown to be clinically useful in the biological therapy of certain myeloid and T-cell malignancies, whereas CD20 has proven to be an effective target in B-cell lymphoma immunotherapy. Both retinoic acid derivatives and anti-CD20 monoclonal antibodies have also been shown to induce apoptosis of malignant cells in vitro. Retinoid-induced apoptosis is thought to be mediated by nuclear retinoid receptor binding and transcriptional activation, whereas CD20 ligation appears to initiate transmembrane Ca(2+) influx with resultant programmed cell death. In this report, we evaluate the in vitro effects of N-(4-hydroxyphenyl) retinamide (4-HPR) with and without anti-CD20 antibodies in B-cell lymphoma lines. We demonstrate that 4-HPR inhibits the growth of malignant B-cells beyond that of all-trans-retinoic acid and 13-cis-retinoic acid. We also show that this 4-HPR-mediated growth inhibition is attributable to apoptosis, is consistent across a variety of malignant B-cell lines (Ramos, Ramos AW, SU-DHL4, and Raji), peaks at 96 to 144 h, and is attainable with concentrations as low as 2 microM. As with CD20-mediated apoptosis, we show that the final common pathway includes caspase activation that can be blocked by 2-val-Ala-Asp-fluoromethyl ketone (z-VAD), a specific inhibitor of caspase function. Coincubation of a 2 microM concentration of 4-HPR and the anti-CD20 antibodies rituximab and tositumomab exhibited a supra-additive increase in levels of apoptosis induction of 24% (P = 0.009) and 42% (P = 0.0019) relative to expected additive levels of these same agents. These in vitro findings suggest that the potential in vivo synergy of these well-tolerated drugs may augment the previously demonstrated clinical activity of anti-CD20 monoclonal antibodies in the treatment of B-cell malignancies.
