T‐cell‐depleted allogeneic bone marrow transplantation for acute leukaemia using Campath‐1 antibodies and post‐transplant administration of donor's peripheral blood lymphocytes for prevention of relapse (1995)

One hundred and forty-six patients with acute leukaemia (81 with ANLL and 65 with ALL) received allogeneic bone marrow transplantation from their fully matched siblings. 121 patients underwent T-cell depletion (TCD) using Campath 1 monoclonal rat anti-human lymphocyte (CDw52) antibodies; 67 with Campath 1M and 54 with Campath 1G isotypes. Patients were conditioned for transplant using either total body irradiation combined with chemotherapy (125 patients) or busulfan and cyclophosphamide (21 patients). 112 recipients of T-cell depleted allografts received in addition total lymphoid irradiation (TLI) for prevention of rejection. Engraftment of neutrophils (> 0.5 x 10(9)/l) and platelets (> 25 x 10(9)/l) occurred on days 15 and 18, and on days 18 and 20 in recipients of Campath 1M and Campath 1G treated marrows respectively. Rejection was documented in 6.8% of T-cell depleted transplants. Leukaemia relapse-free survival at 2 years was 83% for patients transplanted in first CR, 76% in second CR (P2 = 0.34) and 42% in advanced leukaemia (P2 = 0.009). 81 marrow recipients, 38 with Campath 1M and 43 with Campath 1G treated marrow, received post-transplant graded increments of donor's peripheral blood lymphocytes (PBL) to induce graft-versus-leukaemia (GVL) effects. Administration of donor's PBL was associated with clinically significant GVHD and with decreased relapse rate especially in patients with ALL. Our data suggest that in patients receiving marrow allografts depleted of T cells by Campath 1 monoclonal antibodies, rejection can be reduced by adequate pregrafting immunosuppression. In patients with advanced disease, post-transplant cell-mediated immunotherapy (CMI) using donor's PBL may be beneficial; however, further studies are needed to define the optimal schedule of CMI for safe and effective prevention of relapse following TCD bone marrow transplantation in malignant haematological diseases.
Targeting CCR2 or CD18 Inhibits Experimental In-Stent Restenosis in Primates (2002)

A central role for leukocytes in neointimal hyperplasia after arterial injury is suspected. However, the relative importance of neutrophils and monocytes in balloon or stent-induced injury are not well understood, and mechanistic targeting of leukocyte recruitment or function is crude. We determined the temporal and spatial distribution of different leukocytes after balloon and stent-induced injury in primate iliac arteries. Based on these data, we targeted neutrophil and monocyte recruitment selectively after angioplasty or stent implantation and demonstrated that monocyte-specific blockade achieved via blockade of the MCP-1 receptor CCR2, was effective at reducing neointimal hyperplasia after stenting. In contrast, combined neutrophil and monocyte blockade achieved by targeting the leukocyte β 2 -integrin β-subunit CD18 was required to reduce neointimal hyperplasia after balloon injury. Distinct patterns of leukocyte infiltration in balloon versus stent-injured arteries predict distinct mechanisms for antiinflammatory strategies targeting neutrophils or monocytes in primates and may assist design of effective clinical strategies for optimizing vascular interventions.

Identification of amino acids controlling the low-pH-induced conformational change of rabies virus glycoprotein (1996)

The glycoprotein (G) of rabies virus assumes at least three different conformations: the native state detected at the viral surface above pH 7, the activated state involved in the first step of the fusion process, and the fusion-inactive conformation (I). A new category of monoclonal antibodies (MAbs) which recognized specifically the I conformation at the viral surface has recently been described. These MAbs (17A4 and 29EC2) became neutralizing when the virus was preincubated at acidic pH to induce the conformational change toward the I state of G. Mutants escaping neutralization were then selected. In this study, we have investigated the fusion and the low-pH-induced fusion inactivation properties of these mutants. All of these mutants have fusion properties similar to those of the CVS parental strain, but five mutants (E282K, M44I, M44V, V392G, and M396T) were considerably slowed in their conformational change leading to the I state. These mutants allow us to define regions that control this conformational change. These results also reinforce the idea that structural transition toward the I state is irrelevant to the fusion process. Other mutations in amino acids 10, 13, and 15 are probably located in the epitopes of selecting MAbs. Furthermore, in electron microscopy, we observed a hexagonal lattice of glycoproteins at the viral surface of mutants M44I and V392G as well as strong cooperativity in the conformational change toward the I state. This finding demonstrates the existence of lateral interactions between the spikes of a rhabdovirus.
Context data in geo-referenced digital photo collections (2004)

Given time and location information about digital photographs we can automatically generate an abundance of related contextual metadata, using off-the-shelf and Web-based data sources. Among these are the local daylight status and weather conditions at the time and place a photo was taken. This metadata has the potential of serving as memory cues and filters when browsing photo collections, especially as these collections grow into the tens of thousands and span dozens of years.
Nitrite: A physiological store of nitric oxide and modulator of mitochondrial function (2013)

Nitrite, long considered a biologically inert metabolite of nitric oxide (NO) oxidation, is now accepted as a physiological storage pool of NO that can be reduced to bioactive NO in hypoxic conditions to mediate a spectrum of physiological responses in blood and tissue. This graphical review will provide a broad overview of the role of nitrite in physiology, focusing on its formation and reduction to NO as well as its regulation of the mitochondrion- an emerging subcellular target for its biological actions in tissues.
Accelerated electron transfer between metal complexes mediated by DNA (1988)

DNA-mediated long-range electron transfer from photoexcited 1,10-phenanthroline complexes of ruthenium, Ru(phen)2(3)+, to isostructural complexes of cobalt(III), rhodium(III), and chromium(III) bound along the helical strand. The efficiency of transfer depended upon binding mode and driving force. For a given donor-acceptor pair, surface-bound complexes showed greater rate enhancements than those that were intercalatively bound. Even in rigid glycerol at 253 K, the rates for donor-acceptor pairs bound to DNA remained enhanced. For the series of acceptors, the greatest enhancement in electron-transfer rate was found with chromium, the acceptor of intermediate driving force. The DNA polymer appears to provide an efficient intervening medium to couple donor and acceptor metal complexes for electron transfer.
Dysfunction of T cell receptor AV24AJ18+,BV11+ double-negative regulatory natural killer T cells in autoimmune diseases (2001)

These findings strongly suggest that patients with autoimmune diseases can be divided into two groups (alpha-GalCer responders and nonresponders). They also suggest that the reduced numbers of NKT cells in patients with autoimmune diseases may be due to an inadequate amount of alpha-GalCer-like natural ligands (i.e., adequate in only 48.6% of patients) for the induction of NKT cells in vivo, or to a dysfunction in the NKT cells themselves (in 51.4% of patients).

Rapid infusion of esketamine for unipolar and bipolar depression: a retrospective chart review (2017)

The present study demonstrates that rapid infusion of esketamine is possibly not the optimal choice to administer this drug for treatment-resistant depression due to tolerability reasons. Further controlled studies are required to investigate efficacy, safety, and tolerability profiles among the different types of ketamines and methods of using this drug in depressed patients.
Engineering proteins for nonnatural environments (1993)

The ability to use proteins in nonnatural environments greatly expands their potential applications in biotechnology. Because nature has not paid much attention to optimizing proteins for in vitro applications under conditions that differ substantially from their natural surroundings, there is generally room for improvement through alterations in the amino acid sequence. The most effective approach to this protein engineering task depends on the level to which the molecular basis for the desired property is understood. Consistently successful "rational" design using site-directed mutagenesis requires a high level of understanding of structure and mechanisms or, alternatively, a particularly simple strategy for obtaining the desired feature. An example of a generally applicable and easy-to-implement protein stabilization strategy is metal ion chelation by specific surface dihistidine sites, which can affect thermal stability as well as the protein's ability to withstand denaturants such as guanidinium chloride. Random mutagenesis, on the other hand, can be effective even when structure or mechanisms are poorly understood, provided one can conveniently screen or select for the property of interest. This approach is illustrated by the sequential accumulation of random mutations that greatly enhance the catalytic activity of a serine protease, subtilisin E, in polar organic solvents. The random mutagenesis approach, which mimics the natural evolutionary refinement process, can be used to "coax" enzymes into tolerating nonnatural environments.
Integrin Profile and In Vivo Homing of Human Smooth Muscle Progenitor Cells (2004)

Structure and physical properties of silk fibroin/polyacrylamide blend films (1999)

This article deals with the characterization of blend films obtained by mixing silk fibroin (SF) and polyacrylamide (PAAm). The DSC curves of SF/PAAm blend films showed overlapping of the main thermal transitions characteristic of the individual polymers. The exothermic peak at 218°C, assigned to the β-sheet crystallization of silk fibroin, slightly shifted to a lower temperature by blending. The weight-retention properties (TG) of the blend films were intermediate between those of the two constituents. The TMA response was indicative of a higher thermal stability of the blend films, even at low PAAm content (≤25%), the final breaking occurring at about 300°C (100°C higher than pure SF film). The peak of dynamic loss modulus of silk fibroin at 193°C gradually shifted to lower temperature in the blend films, suggesting an enhancement of the molecular motion of the fibroin chains induced by the presence of PAAm. Changes in the NH stretching region of silk fibroin were detected by FTIR analysis of blend films. These are attributable to disturbance of the hydrogen bond pattern of silk fibroin and formation of new hydrogen bonds with PAAm. The values of strength and elongation at break of blend films slightly improved at 20–25% PAAm content. A sea–island structure was observed by examining the air surface of the blend films by scanning electron microscopy. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 71: 1563–1571, 1999
Genome-wide association study in premature ovarian failure patients suggests ADAMTS19 as a possible candidate gene (2009)

We observed a possible association between POF and a SNP in a biologically plausible candidate gene. Although limited by sample size, this proof-of-principle study's findings reveal ADAMTS19 as a possible candidate gene for POF and thus a larger follow-up study is warranted.
Podocyte detachment and epithelial cell reaction in focal segmental glomerulosclerosis with cellular variants. (1997)

In primary focal segmental glomerulosclerosis with cellular variants the type of epithelial cells that segmentally or globally increased and their relation to sites where podocytes detached from the capillary wall, remain unclear. Two renal samples containing glomeruli with cellular variants were serially examined using transmission electron microscopy. A total of 10 lesions, including 2 collapsing glomerulopathy, 7 cellular lesions, and 1 sclerosis, were examined. Disappearance of the dense basal band of microfilaments from portions of podocytes was followed by detachment from the capillary basement membrane, resulting in segmental denudation of the capillary wall. The defects were not covered by other portions of epithelial cells, when the defects occurred in more central regions of the glomerulus. When detachment of podocytes occurred in the peripheral areas of the glomerulus, the defects were covered with new basement membrane and by other epithelial cells. These epithelial cells were characterized by the formation of intercellular junctional complexes of zonula adherens and desmosomes between each other and with the parietal epithelial cells (PECs), by showing occasional cilia, apoptotic nuclei, and mitosis. Thus, repair is achieved as the defect is covered by the participation of PECs; synechia and glomerular sclerosis result, depending upon the extent of the original podocyte injury.
Sensitive detection of circulating hepatocellular carcinoma cells in peripheral venous blood (1995)

Reverse-transcriptase polymerase chain reaction is a very sensitive method for detecting circulating HCC cells. With this technique, important information for the management of HCC can be acquired, such as the indications for orthotopic liver transplantation in HCC patients. Moreover, use of this detection method may encourage investigation of the mechanism of metastasis in HCC.
Association of lysogenic bacteriophage MAV1 with virulence of Mycoplasma arthritidis (1995)

Mycoplasma arthritidis causes a severe polyarthritis under natural conditions in rats and under experimental conditions in both rats and mice. Although the disease itself has been extensively studied, M. arthritidis virulence factors remain uncharacterized. Comparison of relative arthritogenicity of 20 strains of M. arthritidis revealed that the strains tended to fall into two groups, a highly arthritogenic group, inducing maximum arthritis scores of > or = 11 in rats, and a low-virulence group, inducing maximum scores of < 6. Chromosomal DNA from the more highly arthritogenic strains possessed sequences that hybridized by Southern analysis with a probe prepared from lysogenic M. arthritidis bacteriophage MAV1, while DNA from low-virulence strains did not. One of the low-virulence strains, 158, was experimentally lysogenized with MAV1. Lysogenized 158 showed a significant increase in arthritogenicity over nonlysogenized 158. These data suggest that MAV1 carries a factor that is important in pathogenesis of M. arthritidis-induced arthritis of rats.
Higher Inflammatory Marker Levels in Older Persons: Associations With 5-Year Change in Muscle Mass and Muscle Strength (2009)

Background. There is growing evidence that higher levels of infl ammatory markers are associated with physical decline in older persons, possibly through the catabolic effects of infl ammatory markers on muscle. The aim of this study was to investigate the association between serum levels of infl ammatory markers and loss of muscle mass and strength in older persons. Methods. Using data on 2,177 men and women in the Health, Aging, and Body Composition Study, we examined 5-year change in thigh muscle area estimated by computed tomography and grip and knee extensor strength in relation to serum levels of interleukin-6 (IL-6), C-reactive protein, tumor necrosis factor-alpha (TNF- a ), and soluble receptors (measured in a subsample) at baseline. Results. Higher levels of infl ammatory markers were generally associated with greater 5-year decline in thigh muscle area. Most associations, with the exception of soluble receptors, were attenuated by adjustment for 5-year change in weight. Higher TNF- a and interleukin-6 soluble receptor levels remained associated with greater decline in grip strength in men. Analyses in a subgroup of weight-stable persons showed that higher levels of TNF- a and its soluble receptors were associated with 5-year decline in thigh muscle area and that higher levels of TNF- a were associated with decline in grip strength. Conclusions. TNF- a and its soluble receptors showed the most consistent associations with decline in muscle mass and strength. The results suggest a weight-associated pathway for infl ammation in sarcopenia.

Effect of the peripherally selective κ‐opioid agonist, asimadoline, on adjuvant arthritis (1998)

1. Opioids, though widely used as analgesics, have not been seriously considered as therapy for rheumatoid arthritis. The present study evaluated the dose-effect and time-dependence relationships of a new peripherally selective kappa agonist, asimadoline, in rats with adjuvant arthritis. 2. The arthritis was assessed by a pooled severity index combining the comprehensive criteria of oedema, radiography and histological changes, in the hind limbs. Asimadoline was extremely effective in attenuating joint damage (by up to 80%) when administered parenterally (0.5 to 10 mg kg(-1) day(-1), i.p.) throughout the disease or during its early phase; treatment was less successful if confined to the latter stages. Ten fold higher doses were effective orally. 3. Equimolar doses of a peripherally-selective antagonist, naloxone methiodide, and the kappa-selective antagonist, MR2266, fully reversed the peripheral anti-arthritic effects of asimadoline (5 mg kg(-1) day(-1)), indicating that asimadoline acts through peripheral kappa-opioid receptors. However, an equivalent dose of MR2266 did not fully reverse the anti-arthritic effects of the highest dose of asimadoline (40 mg kg(-1) day(-1)), suggesting a loss of kappa-selectivity at this dose. 4. Asimadoline also exhibited analgesic effects (mechanical nociceptive thresholds) in arthritic but not non-arthritic rats, indicating that inflammation is necessary for asimadoline-induced analgesia. 5. These data confirm our previous findings that kappa-opioids possess anti-arthritic properties and that these effects are mediated via peripheral kappa-receptors. The present results are new in showing that the peripherally acting kappa-opioid agonist, asimadoline, is a potent anti-arthritic agent. Such novel drugs, essentially lacking central side effects, herald new treatments for rheumatoid arthritis.
Functional implications for Kir4.1 channels in glial biology: from K+ buffering to cell differentiation (2008)

Astrocytes and oligodendrocytes are characterized by a very negative resting potential and a high resting permeability for K(+) ions. Early pharmacological and biophysical studies suggested that the resting potential is established by the activity of inwardly rectifying, Ba(2+) sensitive, weakly rectifying Kir channels. Molecular cloning has identified 16 Kir channels genes of which several mRNA transcripts and protein products have been identified in glial cells. However, genetic deletion and siRNA knock-down studies suggest that the resting conductance of astrocytes and oligodendrocytes is largely due to Kir4.1. Loss of Kir4.1 causes membrane depolarization, and a break-down of K(+) and glutamate homeostasis which results in seizures and wide-spread white matter pathology. Kir channels have also been shown to act as critical regulators of cell division whereby Kir function is correlated with an exit from the cell cycle. Conversely, loss of functional Kir channels is associated with re-entry of cells into the cell cycle and gliosis. A loss of functional Kir channels has been shown in a number of neurological diseases including temporal lobe epilepsy, amyotrophic lateral sclerosis, retinal degeneration and malignant gliomas. In the latter, expression of Kir4.1 is sufficient to arrest the aberrant growth of these glial derived tumor cells. Kir4.1 therefore represents a potential therapeutic target in a wide variety of neurological conditions.
