Phase transitions of the starch–water system (1979)

Abstract When purified potato starch granules are heated in the presence of limited amounts of water (less than 1.5 H 2 O: starch, w/w), two endothermic transitions are observed by differential scanning calorimetry. The lower temperature endotherm is always observed at a fixed temperature, 66°C; it is the only endotherm observed when excess water is present. The higher temperature endotherm is observed at increasing temperatures as the water content is decreased. The size of this endotherm decreases with water content. The appearance of the higher temperature endotherm allows the determination of the stoichiometry for full hydration of starch, 14 H 2 O/hexose unit. The shift of the higher temperature endotherm is interpreted as the lowering of the melting point of starch crystallites by solvent water.
Sensor integration for robot navigation: Combining sonar and stereo range data in a grid-based representataion (1987)

Multiple range sensors are essential in mobile robot navigation systems. This introduces the problem of integrating noisy range data from multiple sensors and multiple robot positions into a common description of the environment. We propose a cellular representation called the occupancy grid as a solution to this problem. In this paper, we use occupancy grids to combine range information from sonar and one-dimensional stereo into a two-dimensional map of the vicinity of a robot. Each cell in the map contains a probabilistic estimate of whether it is empty or occupied by an object in the environment. These estimates are obtained from sensor models that describe the uncertainty in the range data. A Bayesian estimation scheme is used to update the existing map with successive range profiles from each sensor. This representation is simple to manipulate, treats different sensors uniformly, and models uncertainty in the sensor data and in the robot position. It also provides a basis for motion planning and creation of higherlevel object descriptions.
Measurement of ultra-steep edge, high rejectionfibre Bragggrating filters (1995)

Fibre grating reflection filters with fully resolved extinctions greater than 64 dB and edge widths less than 1 nm have been fabricated in photosensitive optical fibres. Filters have been cascaded to give &gt;74 dB of rejection.
Reactive Oxygen Species Formation by Polymorphonuclear Cells and Mononuclear Cells as a Risk Factor of Cardiovascular Diseases (2006)

To better identify patients at high risk for cardiovascular events, several markers of risk have been proposed for use in screening. Recently, oxidative stress and inflammation have been evaluated as potential tools for prediction of the risk of cardiovascular events. Among them, we have measured reactive oxygen species (ROS) formation by polymorphonuclear cells (PMNs) and mononuclear cells (MNCs), since they may be a possible link between inflammation and oxidative stress. ROS formation by PMNs and MNCs was measured by a gated flow cytometric assay. Such biotechnological method of measuring ROS formation by PMNs and MNCs will make it possible that we measure vascular oxidative stress and vascular inflammation at the same time from only small amount of blood. We will state in this review that ROS formation by PMNs and MNCs are regulated by different mechanisms, although PMNs and MNCs are circulating in the same blood. Moreover, we will state that ROS formation by PMNs are regulated by blood pressure, Hb A(1C) and oxidided LDL. ROS formation by MNCs are regulated by vascular inflammation, and that ROS formation by MNCs are also related to various cardiovascular risks such as LV mass, norepinephrine, IMT, and nocturnal blood pressure.
Impact of therapy with epoetin alfa on clinical outcomes in patients with nonmyeloid malignancies during cancer chemotherapy in community oncology practice. Procrit Study Group. (1997)

Epoetin alfa is effective in improving the functional status and quality of life in anemic cancer patients receiving chemotherapy, as well as increasing hemoglobin level and decreasing transfusion requirements. Improvement in functional status can be attributed to an increase in hemoglobin level, demonstrating that quality of life in this group of patients can be improved by aggressively treating anemia. Further studies will be required to define the optimal doses and schedules for epoetin alfa.

Interstitial Collagenase (MMP-1) Expression in Human Carotid Atherosclerosis (1995)

This study demonstrates that MMP-1 is expressed by several cell types in human carotid atherosclerosis and that there is a correlation between the expression of the protease and histopathological evidence of plaque instability. Since MMP-1 may degrade the major structural collagens of the plaque, expression of the protease by macrophages in regions critical to plaque integrity could contribute to plaque expansion, rupture, and hemorrhage.
VCP/p97 AAA-ATPase Does Not Interact with the Endogenous Wild-Type Cystic Fibrosis Transmembrane Conductance Regulator (2007)

The cystic fibrosis transmembrane conductance regulator (CFTR) is a chloride channel that is defective in cystic fibrosis. The most common mutation, DeltaF508 CFTR, is retained in the endoplasmic reticulum, retrotranslocated into the cytosol, and degraded by the proteasome. In a proteomics screen to identify DeltaF508 CFTR interacting proteins, we found that valosin-containing protein (VCP)/p97, a Type II AAA ATPase that is a component of the retrotranslocation machinery, binds DeltaF508 CFTR, and this interaction is stabilized by proteasomal inhibition. Since wild-type (WT) CFTR has been reported to be inefficiently processed during biogenesis with as much as 75% of the newly synthesized protein degraded by the proteasome, we examined the VCP interaction in Calu-3, T-84, and 16HBE, three epithelial cell lines that endogenously express WT CFTR. The results indicate that when WT CFTR processing is efficient, as demonstrated in Calu-3 cells, VCP does not interact. Interestingly, overexpression of recombinant WT CFTR in Calu-3 cells results in inefficient processing and VCP interaction, demonstrating that CFTR processing efficiency and the VCP interaction are tightly coupled. Furthermore, induction of ER stress and activation of the unfolded protein response result in inefficient processing of WT CFTR in Calu-3 cells and promote the WT CFTR-VCP interaction. The results support the hypothesis that components of the retrotranslocation machinery such as VCP do not interact with CFTR in epithelial cells that endogenously express WT CFTR, since under normal conditions the processing of the WT protein is efficient.
Plastic ELISA-on-a-Chip Based on Sequential Cross-Flow Chromatography (2006)

A plastic chip that can perform immunoassays using an enzyme as signal generator, i.e., ELISA-on-a-chip, was developed by incorporating an immunostrip into channels etched on the surfaces of the chip. To utilize an analytical concept of cross-flow chromatography, the chip consisted of two cross-flow channels in the horizontal and vertical directions. In the vertical channel, we placed a 2-mm-wide immunostrip for cardiac troponin I (cTnI), which was identical to a conventional rapid test kit except for the utilization of an enzyme, horseradish peroxidase (HRP), as tracer. An enzyme substrate supply channel and a horizontal flow absorption pad compartment were transversely arranged on each lateral side of the signal generation pad of the strip, respectively. Upon application of a sample containing cTnI, it migrated vertically through the membrane strip by capillary action, and antigen-antibody binding occurred. After 15 min, the horizontal flow was initiated by the addition of a chromogenic substrate solution for HRP into the supply channel and by partial superimposition of the horizontal flow absorption pad onto the signal generation pad. A color signal proportional to the analyte concentration was produced on this pad, measured after 5 min as optical densities using a digital camera-based detector, and quantified by integration of the densities under the peak after normalization. Its calibration curve indicated that the detection limit of the chip was approximately 0.1 ng/mL and its quantification limit was 0.25 ng/mL. In measuring blindly prepared samples, the chip performance correlated with that of a reference system, Beckman Coulter Access, within 2.5-fold discrepancy at the detection limit.
Immobilization of Plasminogen Activator, Urokinase, on Nylon (1978)

Urokinase (UK), a fibrinolytic enzyme activator purified from human material was immobilized on nylon using different procedures. One was a modified method of immobilization of antigen or antibody initially carried out by Edelman and others in 1971 (Procedure I). The other was our newly devised method (Procedure II) (Sugitachi et al. 1976). Major specificities of the immobilized UK are as follows: 1. The UK revealed properties of a plasminogen activator and the optimum pH of the immobilized UK was between 7.2 and 7.4, these values being in good parallel with that of soluble UK. The immobilized UK maintained a stable fibrinolytic activity after long-term preservation and heat-treatment. 2. As the fibrinolytic activity of immobilized UK was found to be inhibited by the antiplasmin in human plasma, an antiplasmin inhibitor was immobilized on the nylon together with the UK. The antiplasmin activity was to some extent prevented using this procedure. 3. Nylon tubes immobilized with UK and antiplasmin inhibitor were used for thrombotic coagulation studies carried out according to the method of Chandler. Thrombus formation time (TFT) of UK-immobilized tubes was 30 min, while that of the non-treated tubes was no longer than 10 min.
Diverse Effects of Pathogenic Mutations of Parkin That Catalyze Multiple Monoubiquitylation in Vitro (2005)

Mutational dysfunction of PARKIN gene, which encodes a double RING finger protein and has ubiquitin ligase E3 activity, is the major cause of autosomal recessive juvenile Parkinsonism. Although many studies explored the functions of Parkin, its biochemical character is poorly understood. To address this issue, we established an E3 assay system using maltose-binding protein-fused Parkin purified from Escherichia coli. Using this recombinant Parkin, we found that not the front but the rear RING finger motif is responsible for the E3 activity of Parkin, and it catalyzes multiple monoubiquitylation. Intriguingly, for autosomal recessive juvenile Parkinsonism-causing mutations of Parkin, whereas there was loss of E3 activity in the rear RING domain, other pathogenic mutants still exhibited E3 activity equivalent to that of the wild-type Parkin. The evidence presented allows us to reconsider the function of Parkin-catalyzed ubiquitylation and to conclude that autosomal recessive juvenile Parkinsonism is not solely attributable to catalytic impairment of the E3 activity of Parkin.
Glucose transporters (GLUT and SGLT): expanded families of sugar transport proteins (2003)

The number of known glucose transporters has expanded considerably over the past 2 years. At least three, and up to six, Na+-dependent glucose transporters (SGLT1-SGLT6; gene name SLC5A) have been identified. Similarly, thirteen members of the family of facilitative sugar transporters (GLUT1-GLUT12 and HMIT; gene name SLC2A) are now recognised. These various transporters exhibit different substrate specificities, kinetic properties and tissue expression profiles. The number of distinct gene products, together with the presence of several different transporters in certain tissues and cells (for example, GLUT1, GLUT4, GLUT5, GLUT8, GLUT12 and HMIT in white adipose tissue), indicates that glucose delivery into cells is a process of considerable complexity.
Shape memory polymers with built-in threshold temperature sensors (2008)

The design, fabrication and characterization of a new shape memory polymer (SMP) with built-in temperature sensing capabilities are reported. The material was prepared by incorporating a fluorescent, chromogenic oligo(p-phenylene vinylene) dye into a cross-linked poly(cyclooctene) (PCO) matrix via guest diffusion. The dye concentration was chosen to allow for self-assembly of the dye upon drying, resulting in the formation of excimers. Exposure of these phase-separated blends to temperatures above the melting point (Tm) of the PCO leads to dissolution of the dye molecules, and therefore causes a pronounced change of their absorption and fluorescence color. The optical changes are reversible; i.e., the aggregate absorption and emission are restored upon cooling below Tm. The color is dictated by the phase behavior and is independent of the mechanical state of the SMP. Thus the effect allows one to monitor reaching of the set/release temperature of the polymer.
Detection of Polypeptides on Immunoblots Using Secondary Antibodies or Protein A (2003)

Immunoblotting provides a simple and effective method for identifying specific antigens in a complex mixture of proteins. Initially, the constituent polypeptides are separated using SDS-polyacrylamide gel electrophoresis, or a similar technique, and then are transferred either electrophoretically or by diffusion onto a nitrocellulose filter. Once immobilized on a sheet of nitrocellulose, specific polypeptides can be identified using antibodies that bind to antigens retained on the filter and subsequent visualization of the resulting antibody-antigen complex. This chapter describes conditions suitable for binding antibodies to immobilized proteins and methods for locating these antibody-antigen complexes using appropriately labeled ligands. These methods are based on those of Blake et al. (1), Burnette (2), and Towbin et al. (3).
Nucleotide Sequence of Plasmid pCNB1 from Comamonas Strain CNB-1 Reveals Novel Genetic Organization and Evolution for 4-Chloronitrobenzene Degradation (2007)

The nucleotide sequence of a new plasmid pCNB1 from Comamonas sp. strain CNB-1 that degrades 4-chloronitrobenzene (4CNB) was determined. pCNB1 belongs to the IncP-1beta group and is 91,181 bp in length. A total of 95 open reading frames appear to be involved in (i) the replication, maintenance, and transfer of pCNB1; (ii) resistance to arsenate and chromate; and (iii) the degradation of 4CNB. The 4CNB degradative genes and arsenate resistance genes were located on an extraordinarily large transposon (44.5 kb), proposed as TnCNB1. TnCNB1 was flanked by two IS1071 elements and represents a new member of the composite I transposon family. The 4CNB degradative genes within TnCNB1 were separated by various truncated genes and genetic homologs from other DNA molecules. Genes for chromate resistance were located on another transposon that was similar to the Tn21 transposon of the class II replicative family that is frequently responsible for the mobilization of mercury resistance genes. Resistance to arsenate and chromate were experimentally confirmed, and transcriptions of arsenate and chromate resistance genes were demonstrated by reverse transcription-PCR. These results described a new member of the IncP-1beta plasmid family, and the findings suggest that gene deletion and acquisition as well as genetic rearrangement of DNA molecules happened during the evolution of the 4CNB degradation pathway on pCNB1.
Anti-CRISPR RNA? (2018)

Bacterial Immunity
Bacteria use the CRISPR-Cas immune system to fend off viruses; viruses use anti-CRISPR proteins to fight back. Some bacteria have acquired anti-CRISPR proteins in their genomes to avoid self-cutting. Meeske and Marraffini report the intriguing possibility that bacteria might also use RNA to inhibit CRISPR-Cas enzymes. Cas13, the effector of the type VI CRISPR-Cas system, is directed by guide RNA to cleave target RNA in cis, which further unleashes its indiscriminate trans RNA-cutting activity. However, extended complementarity between guide and target RNAs locks Cas13 into an inactive state, which prevents both cis and trans cleavage, suggesting an endogenous RNA-based mechanism to regulate Cas13. Cas13 is a powerful tool because of its ability to detect and manipulate RNA. The discovery of “anti-CRISPR RNA” has the potential to diversify and expand Cas13's applications.

Human Melanoma Antigens Recognized by T Lymphocytes. (1996)

Human melanoma antigens and their epitopes recognized by T cells have been identified using a variety of methods. These antigens are classified as 1) melanocyte specific melanosomal proteins (MART-1, gp100, tyrosinase and TRP-1), 2) proteins expressed in testis and a variety of cancers (MAGE-1, MAGE-3, BAGE and GAGE), 3) tumor specific mutated proteins (beta-catenin, MUM-1 and CDK4), and 4) others (p15). Some of the HLA-A2 binding non-mutated melanoma epitopes contained non-dominant anchor amino acids and have relatively low HLA-A2 binding affinity, suggesting that these epitopes were likely to be subdominant or cryptic self determinants. The significant correlation observed between vitiligo development and IL2 based immunotherapy suggested that autoreactive T cells specific for these self peptides were involved in melanoma regression in vivo. In addition, since adoptive transfer into patients of CTL recognizing these epitopes resulted in tumor regression, these epitopes may be tumor rejection antigens. Melanoma reactive CTL were efficiently induced from PBL of patients by in vitro stimulation with PBMC pulsed with these melanoma epitopes and may be useful in adoptive transfer protocols for the treatment of patients with metastatic melanoma. An immunization trial using the MART-1 and gp100 peptides in conjunction with incomplete Freund's adjuvant is in progress. These identified antigens may be useful for the development of new immunotherapies for the treatment of melanoma patients as well as for understanding the mechanisms of anti-tumor immune responses and autoimmune disorders against melanocytes.

In Vitro and In Vivo Antibacterial Activities of TAK-083, an Agent for Treatment of Helicobacter pylori Infection (2001)

The antibacterial activity of TAK-083 was tested against 54 clinical isolates of Helicobacter pylori and was compared with those of amoxicillin, clarithromycin, and metronidazole. The growth-inhibitory activity of TAK-083 was more potent than that of amoxicillin, clarithromycin, or metronidazole (the MICs at which 90% of the strains are inhibited were 0.031, 0.125, 64, and 8 microg/ml, respectively). The antibacterial activity of TAK-083 was highly selective against H. pylori; there was a >30-fold difference between the concentration of TAK-083 required to inhibit the growth of H. pylori and that required to inhibit the growth of common aerobic and anaerobic bacteria. Exposure of H. pylori strains to TAK-083 at the MIC or at a greater concentration resulted in an extensive loss of viability. When four H. pylori strains were successively subcultured in the medium containing subinhibitory concentrations of TAK-083, no significant change in the MICs of this compound was observed. TAK-083 strongly inhibited the formation of tryptophanyl-tRNA in H. pylori while exhibiting little effect on the same system in eukaryotes. TAK-083 was efficacious in the treatment of gastric infection caused by H. pylori in Mongolian gerbils. The results presented here indicate that TAK-083 is a promising candidate for the treatment of H. pylori infection.
