A phase I/II trial of iodine-131–tositumomab (anti-CD20), etoposide, cyclophosphamide, and autologous stem cell transplantation for relapsed B-cell lymphomas (2000)

Relapsed B-cell lymphomas are incurable with conventional chemotherapy and radiation therapy, although a fraction of patients can be cured with high-dose chemoradiotherapy and autologous stem-cell transplantation (ASCT). We conducted a phase I/II trial to estimate the maximum tolerated dose (MTD) of iodine 131 ((131)I)-tositumomab (anti-CD20 antibody) that could be combined with etoposide and cyclophosphamide followed by ASCT in patients with relapsed B-cell lymphomas. Fifty-two patients received a trace-labeled infusion of 1.7 mg/kg (131)I-tositumomab (185-370 MBq) followed by serial quantitative gamma-camera imaging and estimation of absorbed doses of radiation to tumor sites and normal organs. Ten days later, patients received a therapeutic infusion of 1.7 mg/kg tositumomab labeled with an amount of (131)I calculated to deliver the target dose of radiation (20-27 Gy) to critical normal organs (liver, kidneys, and lungs). Patients were maintained in radiation isolation until their total-body radioactivity was less than 0.07 mSv/h at 1 m. They were then given etoposide and cyclophosphamide followed by ASCT. The MTD of (131)I-tositumomab that could be safely combined with 60 mg/kg etoposide and 100 mg/kg cyclophosphamide delivered 25 Gy to critical normal organs. The estimated overall survival (OS) and progression-free survival (PFS) of all treated patients at 2 years was 83% and 68%, respectively. These findings compare favorably with those in a nonrandomized control group of patients who underwent transplantation, external-beam total-body irradiation, and etoposide and cyclophosphamide therapy during the same period (OS of 53% and PFS of 36% at 2 years), even after adjustment for confounding variables in a multivariable analysis.
A Controlled Trial of a Human Papillomavirus Type 16 Vaccine (2002)

Administration of this HPV-16 vaccine reduced the incidence of both HPV-16 infection and HPV-16-related cervical intraepithelial neoplasia. Immunizing HPV-16-negative women may eventually reduce the incidence of cervical cancer.
A novel camera calibration method based on genetic algorithm (2008)

A camera calibration method based on genetic algorithm to conventional non-linear camera calibration optimization methods was presented in this paper. Contrary to the classical non-linear photogrammetric approach, the proposed technique can correctly find the solution without the need of initial guesses. In this method, a more comprehensive camera model was adopted which based on the pinhole model, extended with radial distortions, decentering distortion and thin prism distortions correction. In the process of calibration, calibration precision is improved by imaging at different locations in the whole measurement space. The excellent performance of the proposed technique, such as convergence, accuracy and robustness, was demonstrated.
Absence of fetal liver hematopoiesis in mice deficient in transcriptional coactivator core binding factor beta. (1996)

Core binding factor beta (CBF beta) is considered to be a transcriptional coactivator that dimerizes with transcription factors core binding factor alpha 1 (CBFA1), -2, and -3, and enhances DNA binding capacity of these transcription factors. CBF beta and CBFA2, which is also called acute myeloid leukemia 1 gene, are frequently involved in chromosomal translocations in human leukemia. To elucidate the function of CBF beta, mice carrying a mutation in the Cbfb locus were generated. Homozygous mutant embryos died between embryonic days 11.5-13.5 due to hemorrhage in the central nervous system. Mutant embryos had primitive erythropoiesis in yolk sac but lacked definitive hematopoiesis in fetal liver. In the yolk sac of mutant embryos, no erythroid or myeloid progenitors of definitive hematopoietic origin were detected, and the expression of flk-2/flt-3, the marker gene for early precursor cells of definitive hematopoiesis, was absent. These data suggest that Cbfb is essential for definitive hematopoiesis in liver, especially for the commitment to early hematopoietic precursor cells.
Development of Supervised Link Mining Using Computer Vision and Pattern Mining Approach (2016)

The network type we have discussed and explored so far in social network analysis is generated from the nonverbal communication like email logs or chats through electronic medium that provide a rich set of data for analysis of social interactions between people. For getting data for these kind of interactions, we could only rely on that available data that sometimes conduces biased information and we ended up with nonrealistic consequences. Therefore, we propose a new direction to be looked into to explore the interactions in network generated from a means other than electronic communication. This mode of interactions is expected to yield results that must be more realistic. In this paper, we address the important problem of discovering and analysis of social networks with the help of computer vision. A new link mining technique is proposed with the help of computer vision and pattern mining approach which exhibits two processes: extraction of social networks and establishing a link between frequently interacted people captured from the video data.
Debe ser Texas la Referencia para fijar el Precio del Gas en México (2003)

En el presente artículo se estudia la política de precios óptima para una empresa pública de gas con base en un modelo que considera N demandas domesticas de gas distribuidas sobre una línea de Hotelling. Se encuentra que, a pesar de que la empresa pública importa y exporta gas, no tiene que existir un vínculo directo entre los precios socialmente óptimos para los mercados abastecidos con gas doméstico y los precios internacionales. La política de precios vigente en México no es consistente con este resultado.
Microbial models of mammalian metabolism: microbial reduction and oxidation of pentoxifylline (1984)

Fourteen microorganisms, including fungi, yeasts, and bacteria, were screened for their ability to metabolize the xanthine drug pentoxifylline. Thirteen cultures either reduced the drug to the alcohol metabolite or oxidatively cleaved the ketonic side chain to homologous carboxylic acid metabolites. The alcohol metabolite was the predominant or sole metabolite in all organisms, with conversions ranging from 6 to 91%. Preparative-scale production of the alcohol metabolite with Rhodotorula rubra (ATCC 20129) allowed for the isolation of this product with a 40% yield. Two organisms also produced the carboxylic acid metabolites at low levels (2 to 10%). The routes of metabolism in microbial cultures are the same as those reported in mammalian systems.
Olanzapine versus haloperidol in the treatment of schizophrenia and schizoaffective and schizophreniform disorders: results of an international collaborative trial (1997)

Olanzapine shows a superior and broader spectrum of efficacy in the treatment of schizophrenic psychopathology, with a substantially more favorable safety profile, than haloperidol. It meets several of the criteria for a novel atypical antipsychotic agent.
Direct analysis of tau from PSP brain identifies new phosphorylation sites and a major fragment of N‐terminally cleaved tau containing four microtubule‐binding repeats (2008)

Tangles containing hyperphosphorylated aggregates of insoluble tau are a pathological hallmark of progressive supranuclear palsy (PSP). Several phosphorylation sites on tau in PSP have been identified using phospho-specific antibodies, but no sites have been determined by direct sequencing due to the difficulty in enriching insoluble tau from PSP brain. We describe a new method to enrich insoluble PSP-tau and report eight phosphorylation sites [Ser46, Thr181, Ser202, Thr217, Thr231, Ser235, Ser396/Ser400 (one site) and Thr403/Ser404 (one site)] identified by mass spectrometry. We also describe a 35 kDa C-terminal tau fragment (tau35), lacking the N-terminus of tau but containing four microtubule-binding repeats (4R), that is present only in neurodegenerative disorders in which 4R tau is over-represented. Tau35 was readily detectable in PSP, corticobasal degeneration and 4R forms of fronto-temporal dementia with parkinsonism linked to chromosome 17, but was absent from control, Alzheimer's disease and Pick's disease brain. Our findings suggest the aggregatory characteristics of PSP-tau differ from those of insoluble tau in Alzheimer's disease brain and this might be related to the presence of a C-terminal cleavage product of tau.
Topical Sucralfate Treatment of Anal Fistulotomy Wounds: A Randomized Placebo-Controlled Trial (2011)

The results of this study add support to the evidence that topical sucralfate is a safe and effective method for promoting mucosal healing and for providing analgesia during wound treatment. Patients undergoing anal fistulotomy can benefit from the use of topical application of sucralfate.
Angiotensin II subtype 1-receptor antagonists in the treatment of diabetic nephropathy (2001)

Diabetic nephropathy has become the leading cause of terminal renal failure in all Western nations due to a steady increase of patients with the renal complication of type 2 (non-insulin-dependent) diabetes mellitus. A number of modifiable risk factors have been identified that predispose to and/or accelerate renal disease in patients with diabetes mellitus. Among these, the level of blood pressure, even in the range of normotension according to World Health Organization or Joint National Committee definition, is closely related to the rate of progression of diabetic nephropathy. This has been documented in patients with incipient (microalbuminuric) and in patients with manifest (proteinuric) diabetic renal disease. Consequently, the treatment of even normotensive diabetics has been recommended once microalbuminuria is present, and blood pressure values in the low normal range should be aimed for. The selection of antihypertensive agents is also important, however, since a 'renoprotective effect' has been documented for drugs that interfere with the renin-angiotensin-aldosterone system such as angiotensin converting enzyme inhibitors. Recently, a new class of drugs that selectively inhibits this system by specifically targeting the angiotensin II receptor has been developed. These angiotensin II subtype 1-receptor antagonists are efficacious antihypertensive agents with a side-effect profile similar to placebo. Evidence for a renoprotective effect in patients with diabetic nephropathy from a large controlled clinical trial is still awaited, but data generated in animal experiments and in smaller clinical trials are encouraging. Currently, these drugs are a valuable substitute for angiotensin converting enzyme inhibitors in patients who experience side effects such as intractable cough.
Survival and Function of Hepatocytes on a Novel Three-Dimensional Synthetic Biodegradable Polymer Scaffold With an Intrinsic Network of Channels (1998)

HCs cocultured with nonparenchymal cells can attach to and survive on the 3D polymer scaffolds in both static and flow conditions in the size and configuration used in this study. Flow conditions may provide a more conducive environment for HC metabolism and albumin synthesis than static conditions. The authors hypothesize that flow through directed channels will be necessary for the transfer of large masses of cells when implantation studies are initiated.
Furanonaphthoquinone Analogs Possessing Preferential Antitumor Activity Compared to Normal Cells (1999)

The 50% growth inhibition toxicity (IC50 at 72 h) of 16 synthetic and 2 phytochemical natural analogs of furanonaphthoquinones (naphtho[2,3-b]furan-4,9-dione; FNQ) and 2 analogs of isofuranonaphthoquinones was assayed in vitro in respect to established human cervical cancer and lung adenocarcinoma cells in comparison with human uterine endocervical, tracheal and bronchiolar epithelial cells and fibroblasts. Prostate, cholangio, colon, laryngeal, and tongue carcinoma cell lines and two osteosarcoma cell lines were also used for the assay. The IC50 ratio of normal cells to cancer cells was estimated in order to represent preferential antitumor activity. Two analogs, 2-methylnaphtho[2,3-b]furan-4, 9-dione (FNQ3) and 2-methyl-5(or 8)-hydroxynaphtho[2,3-b]furan-4, 9-dione (FNQ13) showed 10.4 to 14.1 IC50 ratios for all carcinoma cells used, indicating a wide spectrum. Among different carcinomas, there was no difference or variety in the IC50 ratio of a single analog. A moderate IC50 ratio (3.1-4.7) was also found in nine analogs, but seven others were equally cytotoxic (less than 2.6) to both cancer and normal cells. Two isofuranonaphthoquinone derivatives were ineffective, but a thieno derivative was equally cytotoxic to all cells tested. On the basis of the IC50 ratio data and the structure of the furanonaphthoquinones, the following structural activity (selectivity) relationship can be postulated: (i) the presence of an alkyl group at position 2 enhances the IC50 ratio, particularly the methyl group; (ii) a hydroxyl group at position 5 or 8 enhances the IC50 ratio; and (iii) methylation of the phenolic hydroxyl group leads to a decrease of potency. These results indicate that FNQ3, 13, and some other analogs are more preferentially cytotoxic to human tumor cells than to normal cells, unlike mitomycin-C, adriamycin, carboplatin, and methotrexate which are cytotoxic to the both. In nude mouse xenograft tests, FNQ3 demonstrated a significant antitumor activity with T/C% values of 16. 6 to 41.6 against several human carcinoma and osteosarcoma cells.
Geranylgeranyl Diphosphate-Based Inhibitors of Post-Translational Geranylgeranylation of Cellular Proteins (1996)

A novel series of stable analogs of geranylgeranyl diphosphate (GGdP) are described in which the biologically labile diphosphate moiety of GGdP is replaced by portions that can act as stable isosters. The compounds inhibited the geranylgeranyltransferase activity in whole PC-3 prostate cancer cells, as determined by the inhibition of post-translational isoprenylation of the small GTP-binding protein p21rap 1 and the accumulation of unprocessed p21rap 1 in the cytosolic fraction. However, the compounds did not affect the farnesylation of p21ras, as shown by protein immunoprecipitation after whole cell labeling with [3 H]-(R,S)-mevalonolactone. Despite the absence of effects of post-translational processing of p21ras, these compounds proved to be cytotoxic for prostate cancer cells, with half-maximal inhibition of cell growth obtained in the range 18.5-35.1 microM. The GGdP analogs described in the this study are novel, non-peptidic inhibitors of geranylgeranylation that may be active as antitumor agents.
Olfactory centres in Alzheimer's disease: olfactory bulb is involved in early Braak's stages (2001)

In Alzheimer's disease (AD), neurofibrillary tangles spread from the entorhinal cortex to the limbic system, then to neocortical areas, according to the Braak's stages. Olfaction is impaired in early stages of AD. The aim of this study was to describe the pathology of the cortical olfactory centres in relation to Braak's stages determining the earliest site of pathology. We examined 15 control and 15 AD cases. The primary olfactory cortices were involved in more advanced Braak's stages, while olfactory bulbs were damaged in very early (i.e. Braak's stage 0 or 1) stages. These results are supporting the fact that olfaction might be an early marker in AD and argues against the hypothesis that AD pathology is spreading through the olfactory system.
Vertebrate Collagenase Inhibitor. II. Tetrapeptidyl Hydroxamic Acids. (1991)

A series of tripeptidyl analogues carrying hydroxamic acid residue at the C-terminus of the molecule were synthesized, and their inhibitory activities against vertebrate collagenase and other metalloenzymes including bacterial collagenase were examined. Both Z-Pro-Leu-Ala-NHOH and Z-Pro-D-Leu-D-Ala-NHOH showed highly specific and potent inhibitory activity against tadpole and human skin collagenases with an IC50 of 10(-6) M order.
Gas Phase Photoproduction of Diatomic Metal Nitrides During Metal Nitride Laser Chemical Vapor Deposition (1999)

Photolysis of M(NEt2)4 in the gas phase produces diatomic MN molecules (M = Ti, Zr, Hf). TiN and ZrN molecules were identified in the gas phase under CVD conditions by emission spectroscopy and time-of-flight mass spectroscopy. Nanostructured deposits of TiN were formed on quartz substrates by irradiating Ti(NEt2)4 gas at 355 nm. These studies demonstrate the gas phase formation of diatomic molecules having the same stoichiometry as that of the desired solid-phase deposit.
Receptor for Advanced Glycation End Product-Dependent Activation of p38 Mitogen-Activated Protein Kinase Contributes to Amyloid-β-Mediated Cortical Synaptic Dysfunction (2008)

Soluble amyloid-beta (Abeta) peptide is likely to play a key role during early stages of Alzheimer's disease (AD) by perturbing synaptic function and cognitive processes. Receptor for advanced glycation end products (RAGE) has been identified as a receptor involved in Abeta-induced neuronal dysfunction. We investigated the role of neuronal RAGE in Abeta-induced synaptic dysfunction in the entorhinal cortex, an area of the brain important in memory processes that is affected early in AD. We found that soluble oligomeric Abeta peptide (Abeta42) blocked long-term potentiation (LTP), but did not affect long-term depression, paired-pulse facilitation, or basal synaptic transmission. In contrast, Abeta did not inhibit LTP in slices from RAGE-null mutant mice or in slices from wild-type mice treated with anti-RAGE IgG. Similarly, transgenic mice expressing a dominant-negative form of RAGE targeted to neurons showed normal LTP in the presence of Abeta, suggesting that neuronal RAGE functions as a signal transducer for Abeta-mediated LTP impairment. To investigate intracellular pathway transducing RAGE activation by Abeta, we used inhibitors of stress activated kinases. We found that inhibiting p38 mitogen-activated protein kinase (p38 MAPK), but not blocking c-Jun N-terminal kinase activation, was capable of maintaining LTP in Abeta-treated slices. Moreover, Abeta-mediated enhancement of p38 MAPK phosphorylation in cortical neurons was reduced by blocking antibodies to RAGE. Together, our results indicate that Abeta impairs LTP in the entorhinal cortex through neuronal RAGE-mediated activation of p38 MAPK.
Strategy to improve swine influenza virus (SIV) vaccination (2007)

The objective of this study was to assess the effect of concurrent infection with porcine reproductive and respiratory syndrome virus (PRRSV) on the efficacy of an inactivated swine influenza virus (SIV) vaccine. Eight groups of pigs were used in the study. One group was infected with a virulent PRRSV isolate between the two SIV vaccines or at the time of SIV challenge. Control groups included SIV vaccination without PRRSV and pigs infected with SIV and/or PRRSV. Pigs infected with PRRSV during vaccination showed increased levels of macroscopic and microscopic lesions compared to pigs vaccinated against and challenged with only SIV. The presence of PRRSV decreased SIV vaccine efficacy as measured by increased clinical disease and levels of SIV shedding at the acute phase of infection. No alterations in systemic and local antibody response to either SIV vaccination or challenge were observed. These findings demonstrate the impact that PRRSV infection has on SIV vaccine efficacy is important for disease control.
Combination therapy with interferon-? plusN-acetyl cysteine for chronic hepatitis C: A placebo controlled double-blind multicentre study (2000)

A small pilot study in patients with chronic hepatitis C (HCV) infection suggested that antiviral treatment with interferon (IFN) plus N-acetyl cysteine (NAC) was more effective than treatment with interferon alone [Beloqui et al. (1993) Journal of Interferon Research 13:279-282]. An attempt was made to confirm this by performing a placebo-controlled double-blind study at 8 medical centres in Spain and Italy. One-hundred forty-seven patients with chronic HCV infection were investigated, 73 received 3MU IFN-alpha thrice weekly plus NAC 1800 mg daily and 74 received IFN alone. Treatment was continued for 6 months and patients were followed up for a further 6 months. Amongst patients receiving IFN plus NAC, sustained virological responses were observed in 5.5%, transient responses in 26% and non-response in 68.5%. The figures for patients receiving IFN only were 4.1%, 24.3% and 71.6% respectively. Sustained virological response was significantly associated with non-type 1 genotypes (P = 0.045) and with low pre-treatment viraemia levels (P = 0.034). Biochemical response (serum ALT concentrations) correlated with virological outcome in 97% (n = 139) of cases. Patients who experienced a sustained virological response also showed reduction in the Knodell histological activity index. It is concluded that patients with chronic HCV infection are very unlikely to benefit from the addition of N-acetyl cysteine to conventional therapy with interferon-alpha.
cDNA cloning, expression and chromosome mapping of the human STAT4 gene: both STAT4 and STAT1 genes are mapped to 2q32.2→q32.3 (1997)

Studies of transcriptional activation by interferons and a variety of cytokines have led to the identification of a family of proteins that serve as signal transducers and activators of transcription (STAT). STAT4 is phosphorylated following interleukin (IL)-12 stimulation and is essential for IL-12 signal transduction. The human STAT4 cDNA was cloned, and both STAT4 and STAT1 genes were mapped to human chromosome bands 2q32.2-->q32.3 by fluorescence in situ hybridization. These results suggest that STAT4 and STAT1 may have arisen via a tandem gene duplication. However, human STAT1 is expressed ubiquitously, whereas human STAT4 is expressed in several tissues including spleen, heart, brain, peripheral blood cells, and testis.
Transmission and Passage in Horses of the Agent of Human Granulocytic Ehrlichiosis (1995)

The human granulocytotropic ehrlichia and Ehrlichia equi produce similar diseases in their respective host species (humans, horses). Currently, the phylogenetic and biologic relationships of these 2 uncultured pathogens remain unclear. Previous studies have revealed nucleotide sequence similarity approaching identity at the level of the 16S ribosomal RNA gene. To investigate the biologic similarities of these 2 ehrlichiae, the susceptibility of horses to the human agent was tested by intravenous inoculation of infected human blood. The results demonstrate that the human granulocytotropic ehrlichia produces a disease in the horse indistinguishable from that caused by E. equi, providing biologic evidence that these 2 organisms are highly related and potentially conspecific. It is possible that cases of human illness now attributed to human granulocytotropic ehrlichia may in fact be caused by 1 or more strains of an ehrlichia known chiefly as an equine pathogen.
