Cooling load dynamics of rooms with cooled ceilings (1997)

Radiant cooling technologies are emerging in the European market. The dynamic building thermal analysis program ACCURACY has therefore been enhanced so as to calculate cooling loads and analyse annual energy consumption for rooms with cooled-ceiling climate systems. The program addresses the radiant effects of the ceiling panels on thermal comfort and cooling load dynamics. The program was validated against the measured dynamic response of a test room to step heating and step cooling. The underlying principles of the program are given. It is used to calculate the cooling load for an office room. This demonstrates the applicability and significance of the new method.
Design of Experiments for Evaluating Frozen Sperm (1990)

This paper describes the difficulties encountered in evaluating frozen sperm in both animal and human experiments, and discusses the principles of experimental design used to overcome them. Issues influencing the validity of results include randomization strategies and blindness. Issues which bear on the efficiency of design include stratification, pairing and blocking, multifactor designs, and use of covariates. Fundamental questions concerning the impact of study size and negative results are discussed. One approach to combining the results of many small studies, meta-analysis, is presented.
Robotics, computing, and biology An interdisciplinary approach to the analysis of complex genomes (1997)

A staggering amount of genetic information is contained within the DNA of complex organisms such as humans. Of these vast tracts of DNA code, only very small regions actually constitute the 'genes'; with the information ultimately translated into proteins, the basic machinery of cells. However, a complex organism has a cell or tissue type and developmental specific pattern of gene expression which interact in complex networks within and between these cells or tissues. Such a combination of vast tracts of genomic DNA, tissue and developmental specific transcription of small subsets of this information, plus complex interactions between gene products provides a daunting scientific and logistical challenge if a global picture of gene function within complex organisms is to be obtained. This objective can be achieved only through an interdisciplinary combination of biology, computer image analysis, and robotic engineering. The development of a global approach to the understanding of complex genomes is not just an academic challenge. For example, the ability to understand the complex network of gene interactions, or to be able rapidly to screen many genetic samples in parallel, would have enormous consequences for the pharmaceutical and diagnostic industries. The systems described are used in several genetic screening or drug discovery centres that require rapid, reliable, high density screening of small quantities of biological or biologically active material.
A 1200/2400 bps coding suite based on MELP (2003)

This paper presents key algorithm features of the future NATO narrow band voice coder (NBVC), a 1.2/2.4 kbps speech coder with noise preprocessor based on the MELP analysis algorithm. At 1.2 kbps, the MELP parameters for three consecutive frames are grouped into a superframe and jointly quantized to obtain high coding efficiency. The inter-frame redundancy is exploited with distinct quantization schemes for different unvoiced/voiced (U/V) frame combinations in the superframe. Novel techniques used at 1.2 kbps include pitch vector quantization using pitch differentials, joint quantization of pitch and U/V decisions and LSF quantization with a forward-backward interpolation method. A new harmonic synthesizer is introduced for both rates which improves the reproduction quality. Subjective test results indicate that the 1.2 kbps speech coder achieves quality close to the existing federal standard 2.4 kbps MELP coder.
High‐level expression of a neoagarobiose‐producing β‐agarase gene from Agarivorans sp. JAMB‐A11 in Bacillus subtilis and enzymic properties of the recombinant enzyme (2005)

The structural gene for a neoagarobiose-producing beta-agarase of an Agarivorans isolate was expressed in Bacillus subtilis. High-level production of the recombinant enzyme was achieved corresponding to a level of 1.9 x 10(4) units/l of the culture broth. The efficiency of the production is thus 30-fold greater than that of the original strain. The recombinant enzyme (RagaA11) had a molecular mass of 105 kDa and a specific activity of 371 units/mg. The optimal pH and temperature of the enzyme were 7.5-8.0 and 40 degrees C respectively. The enzyme is an endo-type beta-agarase hydrolysing not only agarose, but also neoagarotetraose, to yield neoagarobiose as the final main product, representing approx. 90 mol% of total products. RagaA11 would be useful for industrial production of neoagarobiose.
Molecular Cloning of Complementary DNA Encoding the Avian Receptor for Vitamin D (1987)

Vitamin D3 receptors are intracellular proteins that mediate the nuclear action of the active metabolite 1,25-dihydroxyvitamin D3 [1,25(OH)2D3]. Two receptor-specific monoclonal antibodies were used to recover the complementary DNA (cDNA) of this regulatory protein from a chicken intestinal lambda gt11 cDNA expression library. The amino acid sequences that were deduced from this cDNA revealed a highly conserved cysteine-rich region that displayed homology with a domain characteristic of other steroid receptors and with the gag-erbA oncogene product of avian erythroblastosis virus. RNA selected via hybridization with this DNA sequence directed the cell-free synthesis of immunoprecipitable vitamin D3 receptor. Northern blot analysis of polyadenylated RNA with these cDNA probes revealed two vitamin D receptor messenger RNAs (mRNAs) of 2.6 and 3.2 kilobases in receptor-containing chicken tissues and a major cross-hybridizing receptor mRNA species of 4.2 kilobases in mouse 3T6 fibroblasts. The 4.2-kilobase species was substantially increased by prior exposure of 3T6 cells to 1,25(OH)2D3. This cDNA represents perhaps the rarest mRNA cloned to date in eukaryotes, as well as the first receptor sequence described for an authentic vitamin.
Cholera toxin and cholera toxin B subunit induce IgA switching through the action of TGF-beta 1. (1998)

Cholera toxin (CT) and its B subunit (CTB) are potent immunogens and adjuvants that, either alone or linked to protein Ags, can stimulate mucosal immune responses, modulate the induction of oral tolerance, and stimulate IgA isotype switching. The present studies addressed the mechanisms by which CT and CTB promote IgA switching. CT and rCTB, in the presence of IL-2, significantly increased IgA isotype switching at the clonal level in populations of purified and LPS-activated murine surface IgA- spleen B cells, as determined by ELISA, enzyme linked immunospot assays, and limiting dilution analysis. The IgA stimulatory effects of CT and CTB were independent of the A subunit of CT. CTB and CT did not increase the secretory rate of IgA-producing cells or the clonal burst size of IgA clones, and did inhibit B cell growth. Because TGF-beta 1 also inhibits B cell growth and promotes IgA switching, further studies tested whether the activity of CTB and CT on IgA isotype switching was mediated through TGF-beta 1. Anti-TGF-beta Ab and soluble TGF-beta 1 type IIR inhibited CTB- and CT-stimulated IgA isotype switching. Furthermore, increased TGF-beta 1 mRNA levels and bioactive TGF-beta 1, within a range shown to induce IgA isotype switching, were detected in cultures of surface IgA- B cells stimulated with CT or CTB and IL-2. These data indicate that CTB- and CT-stimulated IgA isotype switching are mediated through TGF-beta 1. The finding that CTB up-regulates TGF-beta 1 activity has important implications for understanding the mechanisms by which CTB promotes both IgA mucosal immunity and oral tolerance.
The kinetic mechanism of myosin V (1999)

Myosin V is an unconventional myosin proposed to be processive on actin filaments, analogous to kinesin on a microtubule [Mehta, A. D., et al. (1999) Nature (London) 400, 590-593]. To ascertain the unique properties of myosin V that permit processivity, we undertook a detailed kinetic analysis of the myosin V motor. We expressed a truncated, single-headed myosin V construct that bound a single light chain to study its innate kinetics, free from constraints imposed by other regions of the molecule. The data demonstrate that unlike any previously characterized myosin a single-headed myosin V spends most of its kinetic cycle (>70%) strongly bound to actin in the presence of ATP. This kinetic tuning is accomplished by increasing several of the rates preceding strong binding to actin and concomitantly prolonging the duration of the strongly bound state by slowing the rate of ADP release. The net result is a myosin unlike any previously characterized, in that ADP release is the rate-limiting step for the actin-activated ATPase cycle. Thus, because of a number of kinetic adaptations, myosin V is tuned for processive movement on actin and will be capable of transporting cargo at lower motor densities than any other characterized myosin.
ParAlign: a parallel sequence alignment algorithm for rapid and sensitive database searches (2001)

There is a need for faster and more sensitive algorithms for sequence similarity searching in view of the rapidly increasing amounts of genomic sequence data available. Parallel processing capabilities in the form of the single instruction, multiple data (SIMD) technology are now available in common microprocessors and enable a single microprocessor to perform many operations in parallel. The ParAlign algorithm has been specifically designed to take advantage of this technology. The new algorithm initially exploits parallelism to perform a very rapid computation of the exact optimal ungapped alignment score for all diagonals in the alignment matrix. Then, a novel heuristic is employed to compute an approximate score of a gapped alignment by combining the scores of several diagonals. This approximate score is used to select the most interesting database sequences for a subsequent Smith-Waterman alignment, which is also parallelised. The resulting method represents a substantial improvement compared to existing heuristics. The sensitivity and specificity of ParAlign was found to be as good as Smith-Waterman implementations when the same method for computing the statistical significance of the matches was used. In terms of speed, only the significantly less sensitive NCBI BLAST 2 program was found to outperform the new approach. Online searches are available at http://dna.uio.no/search/
Glycosylation as a strategy to improve antibody-based therapeutics (2009)

To date, more than 20 recombinant immunoglobulin G (IgG) antibody therapeutics are licensed for the treatment of various diseases. The mechanism of action of recombinant monoclonal antibodies (rMAbs) has been extensively investigated and several distinct pathways have been defined; selective activation of specific pathways may optimize clinical outcomes for different diseases, such as cancer and chronic inflammation. Human IgG is a glycoprotein with oligosaccharides attached at a single site. These are essential to the mode of action of rMAbs, and the antibody efficacy can vary depending on the particular oligosaccharide that is attached. Methods are now becoming available that allow the production of rMAbs bearing pre-selected oligosaccharides - glycoforms - to provide maximum efficacy for a given disease indication. This Review summarizes current knowledge of these methods and avenues for their exploitation in the clinic.
Blood Polymorphonuclear Leukocytes From the Majority of Sickle Cell Patients in the Crisis Phase of the Disease Show Enhanced Adhesion to Vascular Endothelium and Increased Expression of CD64 (1998)

There is increasing interest in the role of blood polymorphonuclear leukocytes (PMNs) in the pathogenesis of sickle cell crisis. We studied the adherence of PMNs from 18 sickle cell patients in crisis, 25 out of crisis, and 43 healthy subjects (controls) to monolayers of human umbilical cord endothelium that were either untreated or pretreated with tumor necrosis factor alpha (TNFalpha). Overall, the PMNs from patients in crisis were more adherent than control PMNs to untreated endothelial monolayers (mean 53% increase; P < .001) and TNFalpha-treated monolayers (mean 41% increase; P < .002). Increased adhesiveness was not associated with an abnormal expression of CD11a, CD11b, CD11c, CD18, CD62L, or CD15. There was an increase in the number of PMNs expressing CD64 in patients in crisis (median value, 44%) compared with patients out of crisis (median, 21%; P = .025) and controls (median, 6.5%; P < .001). Sera from patients in crisis had normal levels of granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, interferon-gamma, TNFalpha, interleukin-1 (IL-1), IL-6, or IL-8 and did not modify the adherence of PMNs or their expression of CD64. Only IFN-gamma induced CD64 expression on PMNs, but this effect was not associated with enhanced binding to endothelium. Because PMNs bound to endothelial monolayers were CD64(+) and CD64-enriched PMNs were 7 times more adherent to endothelial monolayers than CD64-depleted PMNs, it is likely that CD64 is a marker of adherent PMNs. Two of the three anti-CD64 antibodies used in our antibody blocking studies (clones 32.2 and 197) partially inhibited the binding of sickle cell PMNs to untreated endothelium (mean inhibitions of 33% [P = .01] and 21% [P = .03], respectively), whereas only one (clone 197) inhibited binding to TNFalpha-treated endothelium (mean inhibition, 29%; P = . 004). In some patients with sickle cell disease, an enhanced PMN adhesion to vascular endothelium could contribute to the vascular occlusion that characterizes the acute crisis of the disease.
Synthesis and Biological Activity of Four Kinds of Reversed Peptides. (1996)

We have synthesized four kinds of reversed peptides of various physiologically active peptides, which inhibit TNF (tumor necrosis factor) cytotoxicity, produce NGF (nerve growth factor), exert antimicrobial activity and inhibit cell attachment, respectively. They were examined for their biological activity in comparison with that of normal peptides, that is, naturally occurring peptides. The reversed peptides induce similar activities, but to a lesser extent than those of the normal peptides, respectively. These results indicate that there may be conformationally ambiguous binding in some of the naturally occurring ligand-protein interactions. This method may be useful as a tool to rapidly generate a novel lead peptide with the desired biological function from a naturally occurring active peptide.

Prevalence of Human Immunodeficiency Virus Infection among Patients Attending Tuberculosis Clinics in the United States (1992)

In 1988-1989, surveillance for human immunodeficiency virus (HIV) infection was conducted in 20 clinics providing medical care for patients with suspected and confirmed tuberculosis (TB) in 14 cities. A total of 3077 specimens from consecutive patients were tested for HIV after patient identifiers were removed. The median clinic seroprevalence rate was 3.4%, (range, 0-46.3%). The highest rates were found in the Northeast and Atlantic coastal areas. Rates by clinic were highest for persons born in the United States (median, 11.2%) and in the Caribbean region (Haitians, 36%-40%, and Cubans, 16%). Most HIV-infected patients had pulmonary TB, but HIV infections were more frequent in patients with extrapulmonary TB than in pulmonary TB patients (19.8% vs. 10.2%, P less than .0002). For US-born patients, rates did not differ by race or sex. These serosurveillance data indicate widespread HIV infection among TB patients and have important implications for clinical management of TB patients and for TB and AIDS prevention programs. Testing all HIV-infected persons and all TB patients for dual infection is essential to control the interrelated epidemics of AIDS and TB.
Transistor sizing: how to control the speed and energy consumption of a circuit (2004)

We introduce a simple model for calculating transistor sizes of an asynchronous control circuit. The model builds on the theory of logical effort and relates transistor sizes to the speed and energy consumption of a circuit. We show how to calculate transistor sizes quickly, how to calculate the speed limit of a circuit, and how to compare circuits in terms of energy-versus-speed independent of a process technology. We compare three asynchronous control circuits for a FIFO: a chain of C-elements, an asP control, and a GasP control.
Immunocytochemical localization of beta II subspecies of protein kinase C in rat brain. (1989)

The distribution of a subspecies of protein kinase C (PKC) encoded by the beta II sequence in rat central nervous tissue was demonstrated immunocytochemically by using antibodies raised against an oligopeptide having a partial sequence specific for the beta II PKC. The beta II PKC immunoreactivity was widely but discretely distributed in the brain. The distribution of the beta II PKC immunoreactivity differed from that of the beta I and gamma PKC subspecies. The beta II PKC immunoreactivity was found in the perikarya, dendrites, and axons of neuronal cells. Few if any glial cells were stained. Immunoreactive neurons were present in the anterior olfactory nucleus, olfactory tubercle, amygdaloid complex, caudate-putamen, accumbens nucleus, claustrum, dorsal part of the lateral septal nucleus, CA1 region of the hippocampus, subiculum, medial habenular nucleus, cerebral cortex, nucleus of the spinal tract of the trigeminal nerve, nucleus of the solitary tract, and substantia gelatinosa of the spinal cord. In these neurons, the beta II PKC immunoreactivity was seen mainly in the form of cytoplasmic dots and, in some cases, diffusely in the cytoplasm. Under electron microscopy, these immunoreactive large dots appeared to be associated with the Golgi complex, suggesting that the beta II PKC plays a specialized function at the Golgi complex in certain neuronal cell types.

Lack of Protective Immunity Against Reinfection with Hepatitis C Virus (1992)

Some individuals infected with hepatitis C virus (HCV) experience multiple episodes of acute hepatitis. It is unclear whether these episodes are due to reinfection with HCV or to reactivation of the original virus infection. Markers of viral replication and host immunity were studied in five chimpanzees sequentially inoculated over a period of 3 years with different HCV strains of proven infectivity. Each rechallenge of a convalescent chimpanzee with the same or a different HCV strain resulted in the reappearance of viremia, which was due to infection with the subsequent challenge virus. The evidence indicates that HCV infection does not elicit protective immunity against reinfection with homologous or heterologous strains, which raises concerns for the development of effective vaccines against HCV.
A real-time matching system for large fingerprint databases (1996)

With the current rapid growth in multimedia technology, there is an imminent need for efficient techniques to search and query large image databases. Because of their unique and peculiar needs, image databases cannot be treated in a similar fashion to other types of digital libraries. The contextual dependencies present in images, and the complex nature of two-dimensional image data make the representation issues more difficult for image databases. An invariant representation of an image is still an open research issue. For these reasons, it is difficult to find a universal content-based retrieval technique. Current approaches based on shape, texture, and color for indexing image databases have met with limited success. Further, these techniques have not been adequately tested in the presence of noise and distortions. A given application domain offers stronger constraints for improving the retrieval performance. Fingerprint databases are characterized by their large size as well as noisy and distorted query images. Distortions are very common in fingerprint images due to elasticity of the skin. In this paper, a method of indexing large fingerprint image databases is presented. The approach integrates a number of domain-specific high-level features such as pattern class and ridge density at higher levels of the search. At the lowest level, it incorporates elastic structural feature-based matching for indexing the database. With a multilevel indexing approach, we have been able to reduce the search space. The search engine has also been implemented on Splash 2-a field programmable gate array (FPGA)-based array processor to obtain near-ASIC level speed of matching. Our approach has been tested on a locally collected test data and on NIST-9, a large fingerprint database available in the public domain.
Plasma Adiponectin Levels and Risk of Myocardial Infarction in Men (2004)

High plasma adiponectin concentrations are associated with lower risk of MI in men. This relationship can be only partly explained by differences in blood lipids and is independent of inflammation and glycemic status.
