The Etiquette Perspective for Human-Automation Relationships: Applications, Models and Results (2003)

At last year's HFES Annual Meeting, we presented a panel on the topic of The Etiquette Perspective for Human-Automation Relationships asking what etiquette might mean when applied to human-machine interactions and whether a consideration of etiquette in those settings might be a useful addition to our set of design tools. As a result of that panel, a subsequent, multi-day symposium sponsored by the American Association for Artificial Intelligence (Miller, 2002), and additional research, some answers are beginning to emerge. This year's panel will work toward refining the definition of etiquette as it applies to human-automation interaction, illustrating and justifying its utility in design and evaluation (through concrete results whenever possible), and providing suggestions for future work in this area.
Loa loa Infection in Temporary Residents of Endemic Regions: Recognition of a Hyperresponsive Syndrome with Characteristic Clinical Manifestations (1986)

Loiasis in residents of endemic areas is generally manifested by microfilaremia, episodic angioedema, periocular migration of adult worms, modest eosinophilia, and variable antibody levels. In 20 temporary residents who acquired loiasis in West Africa, however, the clinical presentations were markedly different. Only three of the 20 had detectable microfilaremia. Furthermore, these patients often showed a state of marked immunological hyperresponsiveness manifested by very high titers of antibody to filariae, increased levels of serum IgE, and profound hypereosinophilia--to levels greater than 3,000/mm3 in 18 of the 20. These patients were also notable for the increased severity, frequency, and pruritic nature of their angioedema. Also, significant complications occurred in seven of the 20; one patient developed endomyocardial fibrosis and six, renal disease after treatment with diethylcarbamazine. Thirteen of the 20 developed subcutaneous nodules; adult parasites were recovered from three of five of these patients who underwent biopsy. All of the patients responded to therapy with diminution of their clinical symptoms and decreases in levels of eosinophils, IgE, and antibody to filariae.
Assessing Sensor Accuracy for Non-Adjunct Use of Continuous Glucose Monitoring (2014)

Using CGM for insulin dosing decisions is feasible below a certain level of sensor error, estimated in silico at MARD=10%. In our experiments, further accuracy improvement did not contribute substantively to better glycemic outcomes.
Bovine adrenocortical cytochrome P-450(17 alpha). Regulation of gene expression by ACTH and elucidation of primary sequence. (1986)

In the steroidogenic pathway of the adrenal cortex, 17 alpha-hydroxylase cytochrome P-450 (P-450(17 alpha)) is a major regulatory enzyme. Previous studies have shown that stimulation of 17 alpha-hydroxylase activity occurs upon treatment of bovine adrenocortical cells in culture with adrenocorticotropic hormone (ACTH), via cAMP, due to an increase in the enzyme concentration. Alterations in the levels of this enzyme result in pronounced changes in the pattern of steroids produced, with the potent glucocorticoid cortisol, as well as the sex steroids, being products of 17 alpha-hydroxylated steroid precursors. In the present study, the identification and sequencing of two cloned DNA molecules, pB17 alpha-1 and pcD17 alpha-2, which are complementary to mRNA sequences encoding bovine adrenal cortex P-450(17 alpha), are reported. Clone pcD17 alpha-2 contains an open reading frame coding for the complete amino acid sequence of P-450(17 alpha) which consists of 509 amino acids and has a molecular weight of 57,251. By comparison to other forms of cytochrome P-450, we conclude that P-450(17 alpha) is a member of a previously unidentified family within the P-450 multigene superfamily. Single bovine and human mRNA species of approximately equal to 1850 bases in length hybridize to these clones. Regulation of the concentration of this RNA has been studied using bovine adrenocortical cells in culture. Treatment with ACTH or dibutyryl cAMP causes an increase in the content of P-450(17 alpha) RNA in as little as 2 h, and its concentration increases greater than 20-fold by 8 h. In contrast, other steroidogenic enzymes that have been studied respond more slowly to ACTH. Actinomycin D and cycloheximide block induction of P-450(17 alpha) RNA, indicating that regulation of 17 alpha-hydroxylase activity is controlled at the level of transcription and requires ongoing protein synthesis.
Bioconjugation Using Thiols: Old Chemistry Rediscovered to Connect Polymers with Nature’s Building Blocks (2012)

Various pathways to bioconjugates based on thiol chemistry are discussed. Thiol-halogeno, thiol-parafluoro, thiol-ene, thiol-yne, thiol-vinylsulfone and thiol-vinyl sulfone, thiol-maleimide, thiol-bisulfone, and thiol-pyridyl disulfide are well-established synthetic routes discovered in recent years as tools to marry polymers with biomolecules such as carbohydrates, proteins, peptide, DNA, antibodies, or other building blocks from nature.
Polarization-resolved laser-induced breakdown spectroscopy (2009)

It is shown that plasma polarization measurements can be used to enhance the sensitivity of laser-induced breakdown spectroscopy (LIBS). The polarization of the plasma emission is used to suppress the continuum with only slight attenuation of the discrete atomic and ionic spectra. The method is demonstrated for LIBS detection of copper and carbon samples ablated by pairs of femtosecond laser pulses.
Regulation of manganese superoxide dismutase and other antioxidant genes in normal and leukemic hematopoietic cells and their relationship to cytotoxicity by tumor necrosis factor (1993)

Myeloid cells are a major source of superoxide and other oxygen metabolites. As a protective mechanism, cells express antioxidant enzymes including manganese superoxide dismutase (Mn-SOD), copper-zinc SOD (Cu/Zn-SOD), and glutathione peroxidase (GSX-PX). Even though hematopoietic cells are a major source of oxidants, little is known of their expression of antioxidants. We found that seven myeloid leukemic cell lines blocked at different stages of differentiation constitutively expressed Mn-SOD, Cu/Zn-SOD, and GSX-PX RNAs. Level of Mn-SOD activities paralleled levels of Mn-SOD RNA. Terminal differentiation of native HL-60 cells to either granulocytes or macrophages did not alter levels of Mn-SOD RNA but markedly decreased cell division. Myeloid leukemic lines sensitive to cytotoxic effects of tumor necrosis factor (TNF) as well as normal peripheral blood lymphocytes and monocytes, dramatically increased their levels of Mn-SOD RNA in the presence of TNF. In contrast, Cu/Zn-SOD and GSX-PX RNA levels did not increase in these same cells. TNF-resistant leukemic lines had higher constitutive levels of Mn-SOD RNA and activity; and these levels did not change in the presence of TNF. Antisense but not random oligonucleotides to Mn-SOD markedly increased the sensitivity to the inhibitory effects of TNF for both the native HL-60 (TNF-sensitive) and K562 (TNF-resistant) cell lines. Further studies showed that the antisense oligonucleotides entered the cells and resulted in decreased levels of Mn-SOD RNA. The data suggest that Mn-SOD may provide protection against cytotoxicity of TNF in hematopoietic cells.
Systemic and Renal-Specific Sympathoinhibition in Obesity Hypertension (2011)

Chronic pressure-mediated baroreflex activation suppresses renal sympathetic nerve activity. Recent observations indicate that chronic electric activation of the carotid baroreflex produces sustained reductions in global sympathetic activity and arterial pressure. Thus, we investigated the effects of global and renal specific suppression of sympathetic activity in dogs with sympathetically mediated, obesity-induced hypertension by comparing the cardiovascular, renal, and neurohormonal responses to chronic baroreflex activation and bilateral surgical renal denervation. After control measurements, the diet was supplemented with beef fat, whereas sodium intake was held constant. After 4 weeks on the high-fat diet, when body weight had increased ≈50%, fat intake was reduced to a level that maintained this body weight. This weight increase was associated with an increase in mean arterial pressure from 100±2 to 117±3 mm Hg and heart rate from 86±3 to 130±4 bpm. The hypertension was associated with a marked increase in cumulative sodium balance despite an approximately 35% increase in glomerular filtration rate. The importance of increased tubular reabsorption to sodium retention was further reflected by ≈35% decrease in fractional sodium excretion. Subsequently, both chronic baroreflex activation (7 days) and renal denervation decreased plasma renin activity and abolished the hypertension. However, baroreflex activation also suppressed systemic sympathetic activity and tachycardia and reduced glomerular hyperfiltration while increasing fractional sodium excretion. In contrast, glomerular filtration rate increased further after renal denervation. Thus, by improving autonomic control of cardiac function and diminishing glomerular hyperfiltration, suppression of global sympathetic activity by baroreflex activation may have beneficial effects in obesity beyond simply attenuating hypertension.

Improving Precision of Proximity Ligation Assay by Amplified Single Molecule Detection (2013)

Proximity ligation assay (PLA) has been proven to be a robust protein detection method. The technique is characterized by high sensitivity and specificity, but the assay precision is probably limited by the PCR readout. To investigate this potential limitation and to improve precision, we developed a digital proximity ligation assay for protein measurement in fluids based on amplified single molecule detection. The assay showed significant improvements in precision, and thereby also detection sensitivity, over the conventional real-time PCR readout.
Free standing single-crystal silicon microstructures (1995)

Micromachined structures of single-crystal silicon have been fabricated with a view to developing them for a number of potential uses. The structures which are fabricated in (111) orientation silicon are undoped thus permitting the incorporation of active circuit elements in the structures themselves. Moreover no high temperatures, applied voltages or long etch times are used in the fabrication sequence, thereby simplifying the task of integration with circuit processes. The potential uses of these structures include photodiodes with high speed and efficiency, accelerometers, or structures for stress or thermal isolation.
Requirement for natural killer T (NKT) cells in the induction of allograft tolerance (2001)

In this study, we investigated the role of Valpha14 natural killer T (NKT) cells in transplant immunity. The ability to reject allografts was not significantly different between wild-type (WT) and Valpha14 NKT cell-deficient mice. However, in models in which tolerance was induced against cardiac allografts by blockade of lymphocyte function-associated antigen-1/intercellular adhesion molecule-1 or CD28/B7 interactions, long-term acceptance of the grafts was observed only in WT but not Valpha14 NKT cell-deficient mice. Adoptive transfer with Valpha14 NKT cells restored long-term acceptance of allografts in Valpha14 NKT cell-deficient mice. The critical role of Valpha14 NKT cells to mediate immunosuppression was also observed in vitro in mixed lymphocyte cultures in which lymphocyte function-associated antigen-1/intercellular adhesion molecule-1 or CD28/B7 interactions were blocked. Experiments using IL-4- or IFN-gamma-deficient mice suggested a critical contribution of IFN-gamma to the Valpha14 NKT cell-mediated allograft acceptance in vivo. These results indicate a critical contribution of Valpha14 NKT cells to the induction of allograft tolerance and provide a useful model to investigate the regulatory role of Valpha14 NKT cells in various immune responses.
Characterization of human bone marrow fibroblast colony-forming cells (CFU-F) and their progeny (1980)

The bone marrow stromal cell population is comprised of fibroblasts, endothelial cells, fat cells and “reticular cells.” The characteristics and the regulatory role in hematopoiesis of each of these cell types are unknown. A liquid culture system has been used to clone and to characterize human bone marrow fibroblast colony-forming cells (CFU-F). The linear relationship between the number of cells plated and the number of colonies formed suggests that fibroblast colonies originate in a single cell. Bone marrow CFU-F were adherent and nonphagocytic. The majority (90% ± 2%) were less dense than 1.070 g/cu cm. Velocity sedimentation separation demonstrated a heterogeneous CFU-F sedimentation rate, with a modal sedimentation of 4.95 ± 0.15 mm/hr. Analysis of CFU-F proliferative status by the thymidine suicide technique indicated that this cell was noncycling in individuals with undisturbed bone marrow function. Some of the more distinctive products of fibroblasts, other stromal cells, and hematopoietic colony-forming cells were used as positive and negative markers for CFU-F and the cells derived from them in vitro. Complement-mediated cytotoxicity using anti-Ia and anti-factor-VIII antigen antisera did not inhibit fibroblast colony formation. In contrast, a striking reduction of granulocyte-macrophage colony formation (CFU-c) was seen when bone marrow cells were treated with anti-Ia antiserum. Immunofluorescence staining was used to characterize the cells derived from CFU-F in vitro. No staining was observed after incubation of subconfluent cultures with anti-Ia and anti-factor-VIII antigen antisera. A positive immunofluorescent staining was obtained when isolated antibodies against three of the main proteins of bone marrow matrix: type I collagen, type III collagen, and fibronectin were used. Ultrastructural analysis showed that CFU-F progeny, in contrast to endothelial cells, did not contain Weibel-Palade bodies. These data support the conclusion that the colonies described in this study are of fibroblastic nature.
Cell transformation potential of a HER2 transmembrane domain deletion mutant retained in the endoplasmic reticulum. (1991)

The HER2 (c-erbB-2) gene encodes a protein, p185HER2, which possesses all of the structural characteristics and functional properties of a growth factor receptor, although its ligand has not yet been well characterized. HER2 is the human homolog of the rat proto-oncogene neu and is closely related to the gene encoding the epidermal growth factor receptor. Amplification of this gene and overexpression have been found to be a prognostic criterion for a 30% subpopulation of human breast cancer patients. In this study, we investigated the role of the transmembrane-spanning sequence in the biosynthesis and localization of p185HER2. A truncation mutant lacking the cytoplasmic and transmembrane domains was glycosylated and efficiently secreted. However, a mutant lacking only the transmembrane-spanning sequence was incompletely glycosylated and failed to reach the cell surface. Unexpectedly, although this deletion mutant was retained in the endoplasmic reticulum membrane, it was still able to transform NIH 3T3 cells when expressed at high levels.
The p53 tumor suppressor protein is a critical regulator of hematopoietic stem cell behavior (2009)

In response to diverse stresses, the tumor suppressor p53 differentially regulates its target genes, variably inducing cell-cycle arrest, apoptosis or senescence. Emerging evidence indicates that p53 plays an important role in regulating hematopoietic stem cell (HSC) quiescence, self-renewal, apoptosis and aging. The p53 pathway is activated by DNA damage, defects in ribosome biogenesis, oxidative stress and oncogene induced p19 ARF upregulation. We present an overview of the current state of knowledge about p53 (and its target genes) in regulating HSC behavior, with the hope that understanding the molecular mechanisms that control p53 activity in HSCs and how p53 mutations affect its role in these events may facilitate the development of therapeutic strategies for eliminating leukemia (and cancer) propagating cells.
The pyrethrins and related compounds. Part XVIII. Insecticidal 2,2-dimethylcyclopropanecarboxylates with new unsaturated 3-substituents (1974)

Fifty new esters related to the insecticide bioresmethrin [5-benzyl-3-furylmethyl (1R,3R)-2,2-dimethyl-3-(2-methylprop-1-enyl) cyclopropanecarboxylate], having various groups in place of the 2-methylprop-1-enyl side chain, have been synthesised. cis- and trans-3-Formyl-2,2-dimethylcyclopropanecarboxylic esters are obtained by ozonolysis of the corresponding chrysanthemates. Wittig and other reactions with these esters then give the required products. 5-Benzyl-3-furylmethyl esters are obtained by transesterification or via acids obtained by cleavage of t-butyl esters under mild conditions.
Relationship between increasing duodenal lipid doses, gastric perception, and plasma hormone levels in humans (2000)

Duodenal lipid causes gastric relaxation, CCK secretion, and nausea. Vasopressin has been implicated in motion sickness-related nausea. We hypothesized that increasing doses of lipid enhance gastric relaxation and CCK-vasopressin secretion, resulting in a dose-related exacerbation of nausea. Nine healthy subjects received isotonic saline or lipid (1, 2, or 3 kcal/min, L1, L2, L3) duodenally. Changes in gastric volume, sensations, and plasma hormone levels were assessed during infusions and isobaric gastric distensions. Lipid infusions increased gastric volume, plasma CCK (but not vasopressin) levels, and gastric compliance during distensions, compared with saline. Plasma CCK levels were related to the dose of lipid administered [CCK levels at 30 min (pmol/l), saline: 1.1 +/- 0.2, L1: 1.8 +/- 0.2, L2: 3.0 +/- 0.2, L3: 4.3 +/- 0.6]. During distensions, nausea increased in intensity with increasing doses of lipid [score (where 0 is no sensation and 100 is strongest sensation), saline: 7 +/- 4, L1: 19 +/- 7, L2: 44 +/- 7, L3: 66 +/- 8]; however, no further rise in plasma CCK occurred. Because neither lipid nor distension alone induced significant nausea, we conclude that the interaction between these stimuli together with a modulation by CCK is responsible for the effects observed. Vasopressin is not involved in lipid- and distension-induced nausea.
Metabolic evolution of energy-conserving pathways for succinate production in Escherichia coli (2009)

During metabolic evolution to improve succinate production in Escherichia coli strains, significant changes in cellular metabolism were acquired that increased energy efficiency in two respects. The energy-conserving phosphoenolpyruvate (PEP) carboxykinase (pck), which normally functions in the reverse direction (gluconeogenesis; glucose repressed) during the oxidative metabolism of organic acids, evolved to become the major carboxylation pathway for succinate production. Both PCK enzyme activity and gene expression levels increased significantly in two stages because of several mutations during the metabolic evolution process. High-level expression of this enzyme-dominated CO(2) fixation and increased ATP yield (1 ATP per oxaloacetate). In addition, the native PEP-dependent phosphotransferase system for glucose uptake was inactivated by a mutation in ptsI. This glucose transport function was replaced by increased expression of the GalP permease (galP) and glucokinase (glk). Results of deleting individual transport genes confirmed that GalP served as the dominant glucose transporter in evolved strains. Using this alternative transport system would increase the pool of PEP available for redox balance. This change would also increase energy efficiency by eliminating the need to produce additional PEP from pyruvate, a reaction that requires two ATP equivalents. Together, these changes converted the wild-type E. coli fermentation pathway for succinate into a functional equivalent of the native pathway that nature evolved in succinate-producing rumen bacteria.
Direct esterification of phosphates with various halides and its application to synthesis of cAMP alkyl triesters (1993)

Esterification of phosphates with various halides, including acid chlorides, phosphoryl trichloride and tin chloride, was achieved in 57–99% isolated yield using silver(I) oxide. The reaction was successfully applied to the preparation of phosphate triesters sensitive to acids and bases. cAMP benzyl esters were also prepared by this method.
UpregulatedTRPand enhanced capacitative Ca2+entry in human pulmonary artery myocytes during proliferation (2001)

A rise in cytosolic Ca(2+) concentration ([Ca(2+)](cyt)) due to Ca(2+) release from intracellular Ca(2+) stores and Ca(2+) influx through plasmalemmal Ca(2+) channels plays a critical role in mitogen-mediated cell growth. Depletion of intracellular Ca(2+) stores triggers capacitative Ca(2+) entry (CCE), a mechanism involved in maintaining Ca(2+) influx and refilling intracellular Ca(2+) stores. Transient receptor potential (TRP) genes have been demonstrated to encode the store-operated Ca(2+) channels that are activated by Ca(2+) store depletion. In this study, we examined whether CCE, activity of store-operated Ca(2+) channels, and human TRP1 (hTRP1) expression are essential in human pulmonary arterial smooth muscle cell (PASMC) proliferation. Chelation of extracellular Ca(2+) and depletion of intracellularly stored Ca(2+) inhibited PASMC growth in media containing serum and growth factors. Resting [Ca(2+)](cyt) as well as the increases in [Ca(2+)](cyt) due to Ca(2+) release and CCE were all significantly greater in proliferating PASMC than in growth-arrested cells. Consistently, whole cell inward currents activated by depletion of intracellular Ca(2+) stores and the mRNA level of hTRP1 were much greater in proliferating PASMC than in growth-arrested cells. These results suggest that elevated [Ca(2+)](cyt) and intracellularly stored [Ca(2+)] play an important role in pulmonary vascular smooth muscle cell growth. CCE, potentially via hTRP1-encoded Ca(2+)-permeable channels, may be an important mechanism required to maintain the elevated [Ca(2+)](cyt) and stored [Ca(2+)] in human PASMC during proliferation.
