Roles of Cartilage Matrix Proteins, Chondromodulin-I and -II, in Endochondral Bone Formation: A Review (1996)

Insulin induces early chondrogenesis in cultures of a clonal cell-line, ATDC5, which was derived from mouse embryonal carcinoma line AT805. Cartilage-generated matrix components chondromodulin-I (ChM-I) synergistically stimulates growth and differentiation of chondrocytes in the presence or absence of FGF-2. In contrast, ChM-I inhibits the proliferation of vascular endothelial cells and tube formation, thereby further stimulating cartilage growth and inhibiting replacing cartilage by bone in an early stage. Another cartilage-derived chondromodulin-II (ChM-II) also stimulates cartilage growth. However, ChM-II does not inhibit vascularization but stimulates osteoclast differentiation. Therefore, endochondral bone formation is regulated sequentially by cartilage-derived multiple autocrine factors. This opens a new mechanism of regulation of endochondral bone formation.
Sleep Duration and Snoring in Relation to Biomarkers of Cardiovascular Disease Risk Among Women With Type 2 Diabetes (2007)

The associations of sleep duration and snoring with lipid profile, hormone measures, and/or inflammatory markers may partially explain the previously reported relationship between sleep habits and cardiovascular and metabolic disorders.
Cyclic nucleotide-gated channels: structural basis of ligand efficacy and allosteric modulation (1997)

Most working proteins, including metabolic enzymes, transcription regulators, and membrane receptors, transporters, and ion channels, share the property of allosteric coupling. The term ‘allosteric’ means that these proteins mediate indirect interactions between sites that are physically separated on the protein. In the example of ligand-gated ion channels, the binding of a suitable ligand elicits local conformational changes at the binding site, which are coupled to further conformational changes in regions distant from the binding site. The physical motions finally arrive at the site of biological activity: the ion-permeating pore. The conformational changes that lead from the ligand binding to the actual opening of the pore comprise ‘gating’. In 1956, del Castillo and Katz suggested that the competition between different ligands at nicotinic acetylcholine receptors (nAChRs) could be explained by formation of an intermediate, ligand-bound, yet inactive state of the receptor, which separates the active state of the receptor from the initial binding of the ligand (del Castillo &amp; Katz, 1957). This ‘binding-then-gating’, two-step model went beyond the then-prevailing drug-receptor model that assumes a single bimolecular binding reaction, and paralleled Stephenson's conceptual dichotomy of ‘affinity’ and ‘efficacy’ (Stephenson, 1956). In 1965 Monod, Wyman and Changeux presented a simple allosteric model (the MWC model) (Monod et al. 1965) that explained the cooperative binding of oxygen to haemoglobin; it was adopted as an important paradigm for ligand-gated channels soon after its initial formulation (Changeux et al. 1967; Karlin, 1967; Colquhoun, 1973).
Vaccine-induced immunity against cutaneous leishmaniasis in BALB/c mice (1988)

Partially purified antigens, derived from Leishmania infantum or L. major promastigotes and isolated under reducing conditions, were used to immunize BALB/c mice. Three subcutaneous injections of the 64- to 97-kilodalton preparation in conjunction with muramyl dipeptide conferred long-lasting immunity against L. mexicana subsp. mexicana and L. major infection; they led to the development of antibodies neutralizing the infectiousness of promastigotes, induced specific delayed-hypersensitivity reactions, and generated populations of peritoneal macrophages capable of killing amastigotes. Vaccination resulted in no harmful effects, since these antigen neither exacerbated preexisting Leishmania infection nor impeded the formation of antibodies to other antigens administered concomitantly.
An update on Reproductive Technologies with Potential Short‐Term Application in Pig Production (2005)

Over the past decade, there has been an increase in the development and/or in the improvement of emerging reproductive technologies in pigs. Among emerging reproductive technologies with potential short-term application in pig production are: artificial insemination with low number of spermatozoa, cryopreservation of spermatozoa and embryos, sperm sexing, and non-surgical embryo transfer. The following review will give emphasis to recent advancements in these reproductive technologies that are starting to show possibilities of serious applications under field conditions.
Synergistic Inflammation Is Induced by Blood Degradation Products with Microbial Toll‐Like Receptor Agonists and Is Blocked by Hemopexin (2010)

Detection of microbial components by immune cells via Toll-like receptors (TLRs) with subsequent induction of inflammation is essential for host defense. However, an overactive immune response can cause tissue damage and sepsis. The endogenous molecule hemoglobin and its derivative heme are often released into tissue compartments where there is infection in the presence of degrading blood. We found that hemoglobin synergizes with multiple TLR agonists to induce high levels of tumor necrosis factor and interleukin-6 from macrophages and that this synergy is independent of TLR4 and MyD88. In contrast, heme synergized with some but not all TLR agonists studied. Furthermore, the synergy of both hemoglobin and heme with lipopolysaccharide was suppressed by hemopexin, a plasma heme-binding protein. These studies suggest that hemoglobin and heme may substantially contribute to microbe-induced inflammation when bacterial or viral infection coexists with blood degradation and that hemopexin may play a role in controlling inflammation in such settings.
Cardiovascular Considerations in Using Topical, Oral, and Intravenous Drugs for the Treatment of Glaucoma and Ocular Hypertension (2001)

Glaucoma and ocular hypertension are highly prevalent conditions in individuals over the age of 40 and are commonly seen together in patients with cardiovascular disease. Many of the antiglaucoma medications, when systemically absorbed, affect the sympathetic and parasympathetic nervous systems of patients and can cause cardiovascular toxicity. Such adverse effects are frequently associated with the long-term use of potentially toxic agents in elderly people, who are most prone to chronic eye disease. Moreover, patients may not associate their symptoms with the topical eye medications, and consequently may not report adverse drug effects. Drug-drug interactions can also occur when patients are taking medications for both cardiovascular disease and glaucoma. This review focuses on beta-adrenergic blockers as topical antiglaucoma medications and other topical antiglaucoma drugs. The systemic toxicity of these agents is reviewed, along with the possible drug interactions. Brief mention is also made of other antiglaucoma medications used alone and in combination with topical beta-blockers.
Actions of the chemotactic cytokines MCP‐1, MCP‐2, MCP‐3, RANTES, MIP‐1α and MIP‐1β on human monocytes (1995)

The activities of six synthetic CC chemokines, MCP-1, MCP-2, MCP-3, RANTES, MIP-1 alpha and MIP-1 beta on human blood monocytes were studied. All CC chemokines elicited a bimodal migration response in vitro. Highest numbers of migrating cells were obtained with the monocyte chemotactic proteins (MCP) and RANTES, somewhat lower numbers with MIP-1 alpha, and only weak migration with MIP-1 beta. The most potent attractants were MCP-1 and MIP-1 alpha which reached maximum efficacy at 0.1 to 1 nM. All CC chemokines also induced the release of N-acetyl-beta-D-glucosaminidase from cytochalasin B-pretreated monocytes. The MCP were most effective (MCP-1 > MCP-3 > MCP-2), RANTES and MIP-1 alpha showed moderate (1/3 of MCP-1 activity), and MIP-1 beta only minimal activity. Cytosolic free Ca2+ changes and exocytosis were used to monitor receptor desensitization. Marked cross-desensitization was observed among MCP-1, MCP-2 and MCP-3 on the one hand, and RANTES, MIP-1 alpha and MIP-1 beta on the other, indicating receptor sharing within these two subgroups of CC chemokines. The responses to RANTES, MIP-1 alpha and MIP-1 beta were also moderately to markedly desensitized by pretreatment with MCP-1, MCP-2 or MCP-3, while the responses to the MCP were virtually unaffected by pretreatment with RANTES, MIP-1 alpha and MIP-1 beta. These results suggest that the MCP also interact with receptors recognized by RANTES, MIP-1 alpha and MIP-1 beta, but not vice versa. Binding studies were performed with radiolabeled MCP-1 or MIP-1 alpha. All MCP competed readily for labeled MCP-1 yielding a concentration-dependent sigmoidal displacement curve. Displacement with RANTES, MIP-1 alpha and MIP-1 beta was observed at higher concentrations, but was not complete. Radiolabeled MIP-1 alpha was displaced efficiently by MIP-1 alpha or MIP-1 beta, but only partially by RANTES. Of the MCP, only MC-3 completely displaced MIP-1 alpha, while only partial displacement was observed with MCP-1 and MCP-2.
Testing Compounds for Antiviral Activity in Cell Cultures Infected with HIV (2003)

This chapter describes the procedures that can be used to determine compounds that have antiviral activity against HIV. These include: maintenance of lymphoblastoid cell lines, preparation of peripheral blood mononuclear cells (PMMCs), and determination of the infectivity of the HIV stock-supernatant and antiviral assays. The assays described use both acutely and chronically infected cells. Toxicity of compounds is assessed by measuring (14)C uptake. These protocols are used for the evaluation of compounds that can be carried out by a single individual in a Category 3 containment laboratory. The number of compounds analyzed would be about 10, which is a convenient number to fill a single 96-well p24 enzyme-linked immunosorbent assay (ELISA) plate.

Principles of entrainment: diagnostic utility for supraventricular tachycardia. (2008)

Entrainment is an important pacing maneuver that can be used to identify reentry as a tachycardia mechanism and define components of the circuit. This review examines how principles of entrainment can be used to arrive at a firm supraventricular tachycardia diagnosis using a simple algorithm and builds a foundation for the application of entrainment to more complex or unknown circuits.
Grafting: fast, incremental feature selection by gradient descent in function space (2003)

We present a novel and flexible approach to the problem of feature selection, called grafting.Rather than considering feature selection as separate from learning, grafting treats the selection of suitable features as an integral part of learning a predictor in a regularized learning framework. To make this regularized learning process sufficiently fast for large scale problems, grafting operates in an incremental iterative fashion, gradually building up a feature set while training a predictor model using gradient descent. At each iteration, a fast gradient-based heuristic is used to quickly assess which feature is most likely to improve the existing model, that feature is then added to the model, and the model is incrementally optimized using gradient descent. The algorithm scales linearly with the number of data points and at most quadratically with the number of features. Grafting can be used with a variety of predictor model classes, both linear and non-linear, and can be used for both classification and regression. Experiments are reported here on a variant of grafting for classification, using both linear and non-linear models, and using a logistic regression-inspired loss function. Results on a variety of synthetic and real world data sets are presented. Finally the relationship between grafting, stagewise additive modelling, and boosting is explored.
Elastic biodegradable poly(glycolide‐co‐caprolactone) scaffold for tissue engineering (2003)

Cyclic mechanical strain has been demonstrated to enhance the development and function of engineered smooth muscle (SM) tissues, and it would be necessary for the development of the elastic scaffolds if one wishes to engineer SM tissues under cyclic mechanical loading. This study reports on the development of an elastic scaffold fabricated from a biodegradable polymer. Biodegradable poly(glycolide-co-caprolactone) (PGCL) copolymer was synthesized from glycolide and epsilon-caprolactone in the presence of stannous octoate as catalyst. The copolymer was characterized by (1)H-NMR, gel permeation chromatography and differential scanning calorimetry. Scaffolds for tissue engineering applications were fabricated from PGCL copolymer using the solvent-casting and particle-leaching technique. The PGCL scaffolds produced in this fashion had open pore structures (average pore size = 250 microm) without the usual nonporous skin layer on external surfaces. Mechanical testing revealed that PGCL scaffolds were far more elastic than poly(lactic-co-glycolic acid) (PLGA) scaffolds fabricated using the same method. Tensile mechanical tests indicated that PGCL scaffolds could withstand an extension of 250% without cracking, which was much higher than withstood by PLGA scaffolds (10-15%). In addition, PGCL scaffolds achieved recoveries exceeding 96% at applied extensions of up to 230%, whereas PLGA scaffolds failed (cracked) at an applied strain of 20%. Dynamic mechanical tests showed that the permanent deformation of the PGCL scaffolds in a dry condition produced was less than 4% of the applied strain, when an elongation of 20% at a frequency of 1 Hz (1 cycle per second) was applied for 6 days. Moreover, PGCL scaffolds in a buffer solution also had permanent deformations less than 5% of the applied strain when an elongation of 10% at a frequency of 1 Hz was applied for 2 days. The usefulness of the PGCL scaffolds was demonstrated by engineering SM tissues in vivo. This study shows that the elastic PGCL scaffolds produced in this study could be used to engineer SM-containing tissues (e.g. blood vessels and bladders) in mechanically dynamic environments.
Molecular cloning of two isoforms of the plasma membrane Ca2+-transporting ATPase from rat brain. Structural and functional domains exhibit similarity to Na+,K+- and other cation transport ATPases. (1988)

Complementary DNAs for two isoforms of the plasma membrane Ca2+-ATPase from rat brain have been isolated. The cDNAs were identified using an oligonucleotide probe derived from a conserved amino acid sequence of the ATP binding site of the aspartylphosphate family of transport ATPases. The complete nucleotide sequences have been determined, and the primary structures for both isoforms have been deduced. The Mr of isoform 1, which has 1,176 amino acids, is 129,500 and that of isoform 2, which has 1,198 amino acids, is 132,605. A region of isoform 1 exhibits perfect amino acid identity with a fragment consisting of 17 amino acids from the phosphorylation domain of the human erythrocyte calmodulin-sensitive Ca2+-ATPase (James, P., Zvaritch, E.I., Shakhparonov, M.I., Penniston, J.T., and Carafoli, E. (1987) Biochem. Biophys. Res. Commun. 149, 7-12). A comparison of transport ATPases from diverse species has allowed the identification of a sequence that may form part of a second ATP binding site. Amino acid similarity and hydropathy profile comparisons suggest that the transmembrane organization of the plasma membrane Ca2+-ATPase is the same as that of the Na+,K+-ATPase and sarcoplasmic reticulum Ca2+-ATPase; the data indicate that each of these enzymes has an even number of transmembrane domains and that their C termini are located on the cytoplasmic side of the membrane. An arginine-rich sequence that is highly characteristic of the "A" domain of a calmodulin binding site is located near the C termini of both isoforms. This putative A domain is identical in isoforms 1 and 2 but their "B" domains, and the remaining C-terminal sequences, are very different. However, 3'-untranslated sequences of the isoform 1 transcript have the potential to encode a calmodulin binding B domain and a C terminus that is very similar to that of isoform 2. This suggests the possibility that additional diversity may occur via alternative processing of the primary transcript.
Streptomyces griseus aminopeptidase is a calcium‐activated zinc metalloprotein (1989)

A heat-stable aminopeptidase with an N-terminal Ala-Pro-Asp-Ile-Pro-Leu sequence has been purified from Streptomyces griseus by heat treatment followed by gel-exclusion and anion-exchange chromatographic procedures. The enzyme is a monomeric zinc metalloenzyme showing an apparent molecular mass of 33 kDa by sodium dodecyl sulfate/polyacrylamide gel electrophoresis and 21 kDa by gel filtration on Superose 12. Calcium ions bind to the enzyme, pKCa 4.5, and activate it about sixfold when the substrate is leucine-4-nitroanilide (0.4 mM in 50 mM Tris/HCl pH 8.0, 25 degrees C). Binding of Ca2+ also contributes to the thermal stability of the protein. This aminopeptidase may be useful for two-stage assays of bacterial and mammalian metalloendopeptidases; it may also serve in studies of proteolytic enzyme activation by calcium ions.
A solver for the network testbed mapping problem (2003)

Network experiments of many types, especially emulation, require the ability to map virtual resources requested by an experimenter onto available physical resources. These resources include hosts, routers, switches, and the links that connect them. Experimenter requests, such as nodes with special hardware or software, must be satisfied, and bottleneck links and other scarce resources in the physical topology should be conserved when physical resources are shared. In the face of these constraints, this mapping becomes an NP-hard problem. Yet, in order to prevent mapping time from becoming a serious hindrance to experimentation, this process cannot consume an excessive amount of time.In this paper, we explore this problem, which we call the network testbed mapping problem .We describe the interesting challenges that characterize it, and explore its applications to emulation and other spaces, such as distributed simulation. We present the design, implementation, and evaluation of a solver for this problem, which is in production use on the Netbed shared network testbed. Our solver builds on simulated annealing to find very good solutions in a few seconds for our historical workload, and scales gracefully on large well-connected synthetic topologies.
The α4β1 (Very Late Antigen (VLA)-4, CD49d/CD29) and α5β1 (VLA-5, CD49e/CD29) Integrins Mediate β2 (CD11/CD18) Integrin-Independent Neutrophil Recruitment to Endotoxin-Induced Lung Inflammation (2001)

The beta(2) integrin cell adhesion molecules (CAM) mediate polymorphonuclear leukocyte (PMNL) emigration in most inflamed tissues, but, in the lung, other yet to be identified CAMs appear to be involved. In Lewis rats, the intratracheal injection of Escherichia coli-LPS induced acute (6-h) PMNL accumulation in the lung parenchyma (280 x 10(6) by myeloperoxidase assay; PBS control = 35 x 10(6)) and bronchoalveolar lavage fluid (BALF = 27 x 10(6); PBS = 0.1 x 10(6)). Parenchymal accumulation was not inhibited by a blocking Ab to beta(2) integrins and only minimally inhibited (20.5%; p < 0.05) in BALF. We examined the role of alpha(4)beta(1) and alpha(5)beta(1) integrins and of selectins in this PMNL recruitment. Treatment with mAbs to alpha(4)beta(1) or alpha(5)beta(1), even in combination, had no effect on PMNL accumulation induced by intratracheal LPS. However, anti-alpha(4) combined with anti-beta(2) mAbs inhibited PMNL recruitment to the parenchyma by 56% (p < 0.001) and to BALF by 58% (p < 0.01). The addition of anti-alpha(5) mAb to beta(2) plus alpha(4) blockade inhibited PMNL accumulation further (by 79%; p < 0.05). In contrast, blockade of L-, P-, and E-selectins in combination or together with beta(2), alpha(4), and alpha(5) integrins had no effect. LPS-induced BALF protein accumulation was not inhibited by treatment with anti-beta(2) plus alpha(4) mAbs, but was prevented when alpha(5)beta(1) was also blocked. Thus, while selectins appear to play no role, alpha(4)beta(1) and alpha(5)beta(1) function as major alternate CAMs to the beta(2) integrins in mediating PMNL migration to lung and to pulmonary vascular and epithelial permeability.
CD52 is a molecular target in advanced systemic mastocytosis (2014)

Advanced systemic mastocytosis (SM) is an aggressive hematopoietic neoplasm with poor prognosis and short survival times. So far, no curative therapy is available for affected patients. We have identified the cell surface antigen CD52 (CAMPATH-1) as a molecular target expressed abundantly on the surface of primary neoplastic mast cells (MCs) in patients with advanced SM. In contrast, neoplastic MCs of patients with indolent SM and normal MCs expressed only low levels or did not express CD52. To study the mechanisms of CD52 expression and the value of this antigen as a potential therapeutic target, we generated a human MC cell line, designated MCPV-1, by lentiviral immortalization of cord blood-derived MC progenitor cells. Functional studies revealed that activated RAS profoundly promotes surface expression of CD52. The CD52-targeting antibody alemtuzumab induced cell death in CD52(+) primary neoplastic MCs obtained from patients with SM as well as in MCPV-1 cells. NSG mice xenotransplanted with MCPV-1 cells survived significantly longer after treatment with alemtuzumab (median survival: 31 d untreated vs. 46 d treated; P=0.0012). We conclude that CD52 is a novel marker and potential therapeutic target in neoplastic MCs in patients with advanced SM.
