Advantages of Concurrent Biochemotherapy Modified by Decrescendo Interleukin-2, Granulocyte Colony-Stimulating Factor, and Tamoxifen for Patients With Metastatic Melanoma (1999)

PURPOSE: Concurrent biochemotherapy results in high response rates but also significant toxicity in patients with metastatic melanoma. We attempted to improve its efficacy and decrease its toxicity by using decrescendo dosing of interleukin-2 (IL-2), posttreatment granulocyte colony-stimulating factor (G-CSF), and low-dose tamoxifen. PATIENTS AND METHODS: Forty-five patients with poor prognosis metastatic melanoma were treated at a community hospital inpatient oncology unit affiliated with the John Wayne Cancer Institute (Santa Monica, CA) between July 1995 and September 1997. A 5-day modified concurrent biochemotherapy regimen of dacarbazine, vinblastine, cisplatin, decrescendo IL-2, interferon alfa-2b, and tamoxifen was repeated at 21-day intervals. G-CSF was administered beginning on day 6 for 7 to 10 days. RESULTS: The overall response rate was 57% (95% confidence interval, 42% to 72%), the complete response rate was 23%, and the partial response rate was 34%. Complete remissions were achieved in an additional 11% of patients by surgical resection of residual disease after biochemotherapy. The median time to progression was 6.3 months and the median duration of survival was 11.4 months. At a maximum follow-up of 36 months (range, 10 to 36 months), 32% of patients are alive and 14% remain free of disease. Decrescendo IL-2 dosing and administration of G-CSF seemed to reduce toxicity, length of hospital stay, and readmission rates. No patient required intensive care unit monitoring, and there were no treatment-related deaths. CONCLUSION: The data from this study indicate that the modified concurrent biochemotherapy regimen reduces the toxicity of concurrent biochemotherapy with no apparent decrease in response rate in patients with poor prognosis metastatic melanoma.
The sulfur controller-2 negative regulatory gene of Neurospora crassa encodes a protein with beta-transducin repeats. (1995)

The sulfur regulatory system of Neurospora crassa is composed of a set of structural genes involved in sulfur catabolism controlled by a genetically defined set of trans-acting regulatory genes. These sulfur regulatory genes include cys-3+, which encodes a basic region-leucine zipper transcriptional activator, and the negative regulatory gene scon-2+. We report here that the scon-2+ gene encodes a polypeptide of 650 amino acids belonging to the expanding beta-transducin family of eukaryotic regulatory proteins. Specifically, SCON2 protein contains six repeated G beta-homologous domains spanning the C-terminal half of the protein. SCON2 represents the initial filamentous fungal protein identified in the beta-transducin group. Additionally, SCON2 exhibits a specific amino-terminal domain that potentially defines another subfamily of beta-transducin homologs. Expression of the scon-2+ gene has been examined using RNA hybridization and gel mobility-shift analysis. The dependence of scon-2+ expression on CYS3 function and the binding of CYS3 to the scon-2+ promoter indicate the presence of an important control loop within the N. crassa sulfur regulatory circuit involving CYS3 activation of scon-2+ expression. On the basis of the presence of beta-transducin repeats, the crucial role of SCON2 in the signal-response pathway triggered by sulfur limitation may be mediated by protein-protein interactions.

Representation and visualization of variability in a 3D anatomical atlas using the kidney as an example (2006)

Computer-based 3D atlases allow an interactive exploration of the human body. However, in most cases such 3D atlases are derived from one single individual, and therefore do not regard the variability of anatomical structures concerning their shape and size. Since the geometric variability across humans plays an important role in many medical applications, our goal is to develop a framework of an anatomical atlas for representation and visualization of the variability of selected anatomical structures. The basis of the project presented is the VOXEL-MAN atlas of inner organs that was created from the Visible Human data set. For modeling anatomical shapes and their variability we utilize "m-reps" which allow a compact representation of anatomical objects on the basis of their skeletons. As an example we used a statistical model of the kidney that is based on 48 different variants. With the integration of a shape description into the VOXEL-MAN atlas it is now possible to query and visualize different shape variations of an organ, e.g. by specifying a person's age or gender. In addition to the representation of individual shape variants, the average shape of a population can be displayed. Besides a surface representation, a volume-based representation of the kidney's shape variants is also possible. It results from the deformation of the reference kidney of the volume-based model using the m-rep shape description. In this way a realistic visualization of the shape variants becomes possible, as well as the visualization of the organ's internal structures.
Reduction of Flatulence‐Causing Sugars by High Temperature Extrusion of Pinto Bean High Starch Fractions (1992)

ABSTRACT Pinto bean high starch fractions were extruded using a Wenger TX‐52 twin screw extruder. The effect of process temperature and moisture in the barrel on flatulence‐causing sugars was investigated. Levels of flatulence causing sugar were lower in extruded compared to non‐extruded samples with higher reduction at higher process temperature. Sugar content decreased from 5.29% in nonextruded samples to 3.69% in samples extruded at 163°C. Moisture content in the extruder barrel did not significantly affect sugars in the samples. Raffinose and stachyose contents were reduced 47 to 60% by extrusion.
IMMUNOFLUORESCENCE COUNTERSTAINS (1974)

Counterstains in the direct and indirect immunofluorescence methods may be used to reduce or eliminate background nonspecific staining or autofluorescence and to increase cellular and tissue detail. The advantages and disadvantages of a number of such counterstains in terms of (a) elimination of background fluorescence, (b) blocking of specific staining, (c) cellular detail and (d) rapidity of fading are discussed, and a new method of counterstaining nuclei with methyl green is presented. Methyl green counterstain is the procedure of choice when maximal cellular and tissue detail is desired. The lissamine-rhodamine-conjugated bovine serum albumin and eriochrome black methods are especially useful in reducing or eliminating nonspecific staining and tissue autofluorescence.
Strategies for 3D video with wide fields-of-view (2001)

Real three-dimensional images make their full impact only if seen over a wide field-of-view, but those on present three-dimensional video displays rarely span more than 20°. The field-of-view of a multiprojector three-dimensional display can be expanded to 90° or more by a circularly symmetric field lens, and the dark zones typically present between the views of a multiprojector system can be eliminated without ghosting by using a pinhole projector equivalent arrangement and a precise diffuser. A planarised version of the optics has been demonstrated, and if combined with a waveguide screen and microdisplays may give an inexpensive three-dimensional display which has a large, flat screen and wide field-of-view.
Linking Emulsion PCR Haplotype Analysis (2010)

The experimental measurement of haplotype requires the determination of two or more genotypes on the same DNA molecule. Because such measurements are much more complicated than measurements of genotypes, haplotypes are typically inferred using population data for linkage disequilibrium between the markers of interest. We have developed a method for molecular haplotyping, linking emulsion PCR (LE-PCR), and have demonstrated that the method is sufficiently robust to determine haplotypes for multiple markers in a population setting. LE-PCR uses emulsion PCR to isolate single template molecules for simultaneous PCR of widely spaced markers and uses linking PCR to fuse these amplicons into one short amplicon, which maintains the phase of the markers. LE-PCR is illustrated for polymorphisms in human paraoxonase 1 (PON1) that have been shown to affect transcriptional activity and substrate specificity in the detoxification of organophosphates.
Early‐onset degeneration of the intervertebral disc and vertebral end plate in mice deficient in type IX collagen (2007)

A deletion mutation for type IX collagen is associated with connective tissue changes characteristic of musculoskeletal degeneration in bony and cartilaginous tissue regions. Some of the observed changes were similar to cartilage changes in osteoarthritis, while others were more similar to disc degenerative changes in humans. The finding of premature onset of intervertebral disc degeneration in this mouse model may be useful in studies of the pathology and treatment of human disc degeneration.
Comparison of expression in hemopoietic cells by retroviral vectors carrying two genes (1988)

In order to identify factors that influence expression by retroviral vectors in hemopoietic cells, we have compared viral RNA levels in cells infected with several different recombinant viruses. All of the vectors tested carry the neomycin resistance gene and provide for the insertion of a second gene which, in these studies, comprised sequences from the myc or myb oncogenes or the gene encoding granulocyte-macrophage colony-stimulating factor. The vectors utilize two different strategies for the coexpression of the two genes: alternate splicing and the use of a separate internal promoter. We found that expression in hemopoietic cells could be increased by substituting sequences from the myeloproliferative sarcoma virus long terminal repeat for those of the Moloney murine leukemia virus long terminal repeat. However, none of the vectors examined was able to express a second gene at levels equivalent to those achieved by the parental vectors carrying only the neomycin resistance gene. The reasons for this varied with the different vectors and included inefficient splicing and/or a reduction in the level of unspliced transcripts upon insertion of a second gene. Although the basis of the latter phenomenon is not clear, it is probably related to the position--near the 5' long terminal repeat--at which the second gene was inserted, since insertion of the same genes near the 3' end of another vector had no effect on viral RNA levels. In an attempt to circumvent some of these problems, we constructed a vector that employs an internal beta-actin promoter. Although this vector could express granulocyte-macrophage colony-stimulating factor sequences in a responsive hemopoietic cell line, the level of granulocyte-macrophage colony-stimulating factor produced was disappointingly low. The results from these studies suggest approaches to the design of improved vectors for effective expression of genes in hemopoietic cells.
Tau monomer encodes strains (2018)

Tauopathies have diverse presentation, progression, and neuropathology. They are linked to tau prion strains, self-replicating assemblies of unique quaternary conformation, whose origin is unknown. Strains can be propagated indefinitely in cultured cells, and induce unique patterns of transmissible neuropathology upon inoculation into mice. DS9 and DS10 cell lines propagate different synthetic strains that derive from recombinant tau. We previously observed that tau monomer adopts two conformational states: one that is inert (M<sub>i</sub>) and one that is seed-competent (M<sub>s</sub>) (Mirbaha et al., 2018). We have now found that M<sub>s</sub> itself is comprised of multiple stable ensembles that encode unique strains. DS9 monomer inoculated into naive cells encoded only DS9, whereas DS10 monomer encoded multiple sub-strains. Sub-strains each induced distinct pathology upon inoculation into a tauopathy mouse model (PS19). M<sub>s</sub> purified from an Alzeimer's disease brain encoded a single strain. Conversely, M<sub>s</sub> from a corticobasal degeneration brain encoded three sub-strains, in which monomer from any one re-established all three upon inoculation into cells. Seed competent tau monomer thus adopts multiple, stable seed-competent conformations, each of which encodes a limited number of strains. This provides insight into the emergence of distinct tauopathies, and may improve diagnosis and therapy.
Tratamento farmacológico da dependência do álcool (2004)

The pharmacological intervention can play a crucial role in the reduction of craving and drinking and the maintenance of abstinence. This article reviews pharmacotherapy for alcohol dependence with an emphasis on the naltrexone, dissulfiram and acamprosate. The opioid antagonist naltrexone lowers relapse rate, reduces drinking days and prolongs periods of abstinence. Acamprosate restores the normal activity of glutamate and GABA systems. Disulfiram has been shown to be most effective for patients who believe in its efficacy and remain compliant with the treatment. Ondansetron, has shown promise in the early-onset alcohol dependence but needs more extensive study. Topiramate (up to 300 mg per day) was more efficacious than placebo in the treatment of alcohol dependence.
Measurement of Intracellular Calcium Using Bioluminescent Aequorin Expressed in Human Cells (1993)

Changes in intracellular free calcium concentration ([Ca2+]i) are involved in many important physiological responses. Detecting changes in [Ca2+]i is crucial to understanding the physiologic roles of intracellular free calcium. We have characterized changes of [Ca2+]i in human cells transfected with apoaequorin cDNA. When reconstituted in vivo by incubating transfected cells with coelenterazine, aequorin emits light upon binding free calcium and acts as a bioluminescent indicator for calcium. We have used this system to determine the concentration response relationship of serotonin for its receptor. Cells cotransfected with serotonin receptor cDNA and apoaequorin cDNA emitted light upon treatment with serotonin. The light emission responses were saturable and serotonin concentration-dependent, and they were inhibited by serotonin antagonists. Human 293 cells that stably express apoaequorin have been created. This system should facilitate the investigation of [Ca2+]i involvement in physiological and pathophysiological responses.
A Data Model for Audio-Video Data . (1994)

Immunoelectrophoresis revealed the following four protein components in the lung surfactant system of guinea-pigs: albumin, transferrin, IgG, and an organ-specific protein migrating in the beta-globulin range. These proteins probably take part in the formation of the hypophase of the alveolar lining layer and thereby influence the surface properties of the alveolar air-liquid interface.
A Novel Toll-like Receptor That Recognizes Vesicular Stomatitis Virus (2010)

Toll-like receptors (TLRs) are the key molecular sensors used by the mammalian innate immune system to detect various types of pathogens. Tlr13 is a novel and uncharacterized member of the mammalian TLR family. Here we report the cloning and characterization of tlr13. Tlr13 is predominantly expressed in the spleen, particularly in dendritic cells and macrophages. Tlr13 appears to activate a MyD88- and TAK1-dependent TLR signaling pathway, inducing the activation of NF-κB. This receptor can also activate type 1 interferon through IRF7. Furthermore, Tlr13 seems to be another intracellular TLR. Remarkably, cells expressing tlr13 fail to respond to known TLR ligands but instead respond specifically to vesicular stomatitis virus. Cells with the knockdown of tlr13 are highly susceptible to vesicular stomatitis virus infection. Thus, these results provide an important insight into the potential role of the novel Toll-like receptor tlr13 in the recognition of viral infection.
Inhibitory Effect of the TRFK-5 Anti-IL-5 Antibody in a Guinea Pig Model of Asthma (1993)

To investigate the role of IL-5 in airway hyperreactivity and pulmonary eosinophilia, we used a model of allergic asthma in guinea pigs and a neutralizing monoclonal antibody (TRFK-5) directed against murine IL-5. Sensitized guinea pigs were challenged with 1% ovalbumin (OVA) aerosol and assessed for airway eosinophilia (by bronchoalveolar lavage [BAL] and histologic evaluation of airway tissue) and bronchoconstrictor responsiveness to substance P (SP) (as RL100 and Cdyn40) 24 h later. OVA challenge of sensitized animals caused a significant increase in airway responsiveness to SP, with a 4.9-fold decrease in RL100 and a 4.7-fold decrease in Cdyn40. Accompanying this increased sensitivity to SP was a 9-fold increase in eosinophils recovered in BAL and a 4- to 5-fold increase in eosinophils in intrapulmonary bronchial tissue. Intraperitoneal treatment with 10 mg/kg of the IL-5 antibody 2 h before OVA challenge blocked BAL and lung tissue increases in eosinophils but had no effect on the development of airway sensitivity to SP. In contrast, similar treatment with 30 mg/kg of this antibody blocked OVA-induced increased sensitivity to SP as well as BAL and lung tissue eosinophilia. These data suggest a critical and possibly independent role for IL-5 in allergic airway hyperresponsiveness and the accumulation of eosinophils within the lung of the guinea pig.
Neuregulins Signaling via a Glial erbB-2–erbB-4 Receptor Complex Contribute to the Neuroendocrine Control of Mammalian Sexual Development (1999)

Activation of erbB-1 receptors by glial TGFalpha has been shown to be a component of the developmental program by which the neuroendocrine brain controls mammalian sexual development. The participation of other members of the erbB family may be required, however, for full signaling capacity. Here, we show that activation of astrocytic erbB-2/erbB-4 receptors plays a significant role in the process by which the hypothalamus controls the advent of mammalian sexual maturation. Hypothalamic astrocytes express both the erbB-2 and erbB-4 genes, but no erbB-3, and respond to neuregulins (NRGs) by releasing prostaglandin E(2) (PGE(2)), which acts on neurosecretory neurons to stimulate secretion of luteinizing hormone-releasing hormone (LHRH), the neuropeptide controlling sexual development. The actions of TGFalpha and NRGs in glia are synergistic and involve recruitment of erbB-2 as a coreceptor, via erbB-1 and erbB-4, respectively. Hypothalamic expression of both erbB-2 and erbB-4 increases first in a gonad-independent manner before the onset of puberty, and then, at the time of puberty, in a sex steroid-dependent manner. Disruption of erbB-2 synthesis in hypothalamic astrocytes by treatment with an antisense oligodeoxynucleotide inhibited the astrocytic response to NRGs and, to a lesser extent, that to TGFalpha and blocked the erbB-dependent, glia-mediated, stimulation of LHRH release. Intracerebral administration of the oligodeoxynucleotide to developing animals delayed the initiation of puberty. Thus, activation of the erbB-2-erbB-4 receptor complex appears to be a critical component of the signaling process by which astrocytes facilitate the acquisition of female reproductive capacity in mammals.
Deaths: final data for 2004. (2007)

Generally, mortality patterns in 2004 were consistent with long-term trends. Life expectancy in 2004 increased again to a new record level. The age-adjusted death rate declined to a record low historical figure. Although not statistically significant, the decrease in the infant mortality rate is typical of recent trends; except for 2002, the infant mortality rate has either decreased or remained level each successive year from 1958 to 2004.
Adjuvants in Veterinary Vaccines: Modes of Action and Adverse Effects (2003)

Vaccine adjuvants are chemicals, microbial components, or mammalian proteins that enhance the immune response to vaccine antigens. Interest in reducing vaccine-related adverse effects and inducing specific types of immunity has led to the development of numerous new adjuvants. Adjuvants in development or in experimental and commercial vaccines include aluminum salts (alum), oil emulsions, saponins, immune-stimulating complexes (ISCOMs), liposomes, microparticles, nonionic block copolymers, derivatized polysaccharides, cytokines, and a wide variety of bacterial derivatives. The mechanisms of action of these diverse compounds vary, as does their induction of cell-mediated and antibody responses. Factors influencing the selection of an adjuvant include animal species, specific pathogen, vaccine antigen, route of immunization, and type of immunity needed.
2006 Update of Recommendations for the Use of White Blood Cell Growth Factors: An Evidence-Based Clinical Practice Guideline (2006)

Purpose To update the 2000 American Society of Clinical Oncology guideline on the use of hematopoietic colony-stimulating factors (CSF). Update Methodology The Update Committee completed a review and analysis of pertinent data published from 1999 through September 2005. Guided by the 1996 ASCO clinical outcomes criteria, the Update Committee formulated recommendations based on improvements in survival, quality of life, toxicity reduction and cost-effectiveness. Recommendations The 2005 Update Committee agreed unanimously that reduction in febrile neutropenia (FN) is an important clinical outcome that justifies the use of CSFs, regardless of impact on other factors, when the risk of FN is approximately 20% and no other equally effective regimen that does not require CSFs is available. Primary prophylaxis is recommended for the prevention of FN in patients who are at high risk based on age, medical history, disease characteristics, and myelotoxicity of the chemotherapy regimen. CSF use allows a modest to moderate increase in dose-density and/or dose-intensity of chemotherapy regimens. Dose-dense regimens should only be used within an appropriately designed clinical trial or if supported by convincing efficacy data. Prophylactic CSF for patients with diffuse aggressive lymphoma aged 65 years and older treated with curative chemotherapy (CHOP or more aggressive regimens) should be given to reduce the incidence of FN and infections. Current recommendations for the management of patients exposed to lethal doses of total body radiotherapy, but not doses high enough to lead to certain death due to injury to other organs, includes the prompt administration of CSF or pegylated G-CSF.
Effects of Human Somatomedin Preparations on Membrane Transport and Protein Synthesis in the Isolated Rat Diaphragm (1974)

Partially purified preparations of human somatomedin stimulated amino acid and sugar transport and protein synthesis in isolated diaphragms of hypophysectomized rats when added in vitro. These metabolic effects cannot be ascribed to the low level of insulin present in the somatomedin preparations. Effects were obtained with amounts of the preparations that contained less insulin than that required to stimulate membrane transport and protein synthesis in the diaphragm. Further, sugar transport was stimulated by one of the preparations in the presence of a large excess of insulin antibodies. The action of the somatomedin preparations on the transport of amino acids into the diaphragm was found to be qualitatively similar to the effect of insulin on this process, i.e., it is very rapid, and not sensitive to puromycin or theophylline. The later finding would suggest that protein synthesis and shifts in intracellular cyclic nucleotide levels are not involved in mediating the effect of these materials on amino acid transport in the diaphragm.
