Identification of an Antigen from Normal Human Tissue That Crossreacts with the Carcinoembryonic Antigen (1972)

A glycoprotein present in normal human tissue is characterized that is neither organ- nor tumor-specific (nonspecific crossreacting antigen) and that crossreacts (by the Ouchterlony double-diffusion technique) with the carcinoembryonic antigen. This immunological relationship indicates common determinants on the molecules of both antigens. We demonstrate that the nonspecific crossreacting antigen is not a fragment of the carcinoembryonic antigen molecule.
Development and Use of Fluorescent Protein Markers in Living Cells (2003)

The ability to visualize, track, and quantify molecules and events in living cells with high spatial and temporal resolution is essential for understanding biological systems. Only recently has it become feasible to carry out these tasks due to the advent of fluorescent protein technology. Here, we trace the development of highly visible and minimally perturbing fluorescent proteins that, together with updated fluorescent imaging techniques, are providing unprecedented insights into the movement of proteins and their interactions with cellular components in living cells.
SHORT COURSE SINGLE AGENT THERAPY WITH AN LFA-3-IgG1 FUSION PROTEIN PROLONGS PRIMATE CARDIAC ALLOGRAFT SURVIVAL1,2 (1996)

The interaction of T cell costimulatory molecules with their ligands is required for optimal T cell activation. Interference with such interactions can induce antigen unresponsiveness and delay xeno- and allograft rejection. We have previously shown that LFA3TIP, a soluble human lymphocyte function-associated antigen (LFA)-3 construct, binds CD2 and inhibits responses of human T cells in vitro. This study reports the first use of a human fusion protein, LFA3TIP, to significantly prolong primate cardiac allograft survival. Based on our observations that LFA3TIP inhibits baboon allogeneic mixed lymphocyte reactions, we gave baboon recipients of heterotopic cardiac allografts injections of LFA3TIP, 3 mg/kg i.v., for 12 consecutive days, starting 2 days before transplantation. This regimen delayed graft rejection from an average of 10.6 +/- 2.3 days for human IgG-treated controls (n = 5) to an average of 18.0 +/- 5.3 days for LFA3TIP-injected animals (n = 7; P < or = 0.01). Grafts from LFA3TIP-treated animals showed markedly diminished coronary endothelialitis as compared with control animals. LFA3TIP reached peak serum levels of approximately 100 micrograms/ml after 7-9 injections and persisted in the 10-micrograms/ml range for 1 to 2 weeks after the final injection. Despite these blood levels, circulating antibodies to LFA3TIP were not detected in the serum. No renal or hepatic toxicity was noted. The possible mechanism by which LFA3TIP acts to inhibit graft rejection is discussed; success in prolonging graft survival when LFA3TIP is used as a single-agent therapy suggests great potential for this novel therapeutic agent.
Clonal diversity, somatic mutation, and immune memory to phosphocholine-keyhole limpet hemocyanin. (1989)

Group II antibodies to phosphocholine (PC)-keyhole limpet hemocyanin in BALB/c mice are genetically diverse and of a defined binding phenotype which recognizes the hapten, phenyl-PC, and PC coupled to protein but not free PC. We sequenced the V regions of 14 kappa and lambda-bearing group II antibodies. Both types show extensive somatic mutations. The pattern of the mutations differs between kappa and lambda antibodies. The nature of the somatic mutation in lambda chains suggests strong Ag selection on the L chain but not the H chain of the lambda-bearing antibodies. The reverse pattern of selection was observed among kappa-containing antibodies wherein the accumulation of replacement mutations in the CDR of the H chain appears to result from selection while changes in the L chain appear unselected. From these findings it appears that somatic mutation plays a major role in anti-PC-keyhole limpet hemocyanin memory development because all 14 antibodies displayed changes from germ-line sequences.

A Variable Region 3 (V3) Mutation Determines a Global Neutralization Phenotype and CD4-Independent Infectivity of a Human Immunodeficiency Virus Type 1 Envelope Associated with a Broadly Cross-Reactive, Primary Virus-Neutralizing Antibody Response (2002)

The human serum human immunodeficiency virus type 1 (HIV-1)-neutralizing serum 2 (HNS2) neutralizes many primary isolates of different clades of HIV-1, and virus expressing envelope from the same donor, clone R2, is neutralized cross-reactively by HIV-immune human sera. The basis for this cross-reactivity was investigated. It was found that a rare mutation in the proximal limb of variable region 3 (V3), 313-4 PM, caused virus pseudotyped with the R2 envelope to be highly sensitive to neutralization by monoclonal antibodies (MAbs) directed against conformation-sensitive epitopes at the tip of the V3 loop, such as 19b, and moderately sensitive to MAbs against CD4 binding site (CD4bs) and CD4-induced (CD4i) epitopes, soluble CD4 (sCD4), and HNS2. In addition, introduction of this sequence by mutagenesis caused enhanced sensitivity to neutralization by 19b, anti-CD4i MAb, and HNS2 in three other primary HIV-1 envelopes and by anti-CD4bs MAb and sCD4 in one of the three. The 313-4 PM sequence also conferred increased infectivity for CD4(+) CCR5(+) cells and the ability to infect CCR5(+) cells upon all of these four and two of these four HIV-1 envelopes, respectively. Neutralization of R2 by HNS2 was substantially inhibited by the cyclized R2 V3 35-mer synthetic peptide. Similarly, the peptide also had some lesser efficacy in blocking neutralization of R2 by other sera or of neutralization of other primary viruses by HNS2. Together, these results indicate that the unusual V3 mutation in the R2 clone accounts for its uncommon neutralization sensitivity phenotype and its capacity to mediate CD4-independent infection, both of which could relate to immunogenicity and the neutralizing activity of HNS2. This is also the first primary HIV-1 isolate envelope glycoprotein found to be competent for CD4-independent infection.
Short-term Prognostic Value of Lipid Measurements in Patients with Angina pectoris (2000)

We studied the role of various markers of lipid metabolism, hemostasis and inflammation in a two year follow-up of 3,000 patients with angina pectoris, during which time 106 patients experienced myocardial infarction or sudden coronary death. Low levels of high density lipoprotein (HDL) cholesterol and of apolipoprotein (apo) A-I were most strongly associated with increased coronary risk. The relative risk per standard deviation increase was 0.68 for HDL cholesterol (95% confidence interval 0.55 to 0.84) and 0.66 for apoA-I (0.54 to 0.81). These associations were independent of other coronary risk factors, other lipid measurements, hemostatic factors, and C-reactive protein (CRP). The associations of total and LDL cholesterol, triglycerides, apoB, and lipoprotein(a) with coronary events were not independent of HDL cholesterol or hemostatic factors. We conclude that HDL cholesterol or apoA-I, hemostatic risk factors, and CRP are important prognostic markers of coronary events in secondary prevention.
An estimate of the global prevalence and incidence of herpes simplex virus type 2 infection (2008)

The prevalence of HSV-2 is relatively easy to measure since infection is lifelong and has a specific serological test. The burden of disease is less easy to quantify. Despite the often sparse data on which these estimates are based, it is clear that HSV-2 infection is widespread. The dramatic differences in prevalence between regions are worthy of further exploration.
Guidelines for using multiple views in information visualization (2000)

A multiple view system uses two or more distinct views to support the investigation of a single conceptual entity. Many such systems exist, ranging from computer-aided design (CAD) systems for chip design that display both the logical structure and the actual geometry of the integrated circuit to overview-plus-detail systems that show both an overview for context and a zoomed-in-view for detail. Designers of these systems must make a variety of design decisions, ranging from determining layout to constructing sophisticated coordination mechanisms. Surprisingly, little work has been done to characterize these systems or to express guidelines for their design. Based on a workshop discussion of multiple views, and based on our own design and implementation experience with these systems, we present eight guidelines for the design of multiple view systems.
High resolution photoemission study of CdSe and CdSe/ZnS core-shell nanocrystals (2003)

Colloidally prepared CdSe and CdSe/ZnS core-shell nanocrystals passivated with trioctylphosphine/trioctylphosphine oxide and hexadecylamine have been studied by photoelectron spectroscopy with tuneable synchrotron radiation. High-resolution spectra of the Se 3d level in CdSe nanocrystals indicate the bonding of organic ligands not only to surface Cd but also to surface Se atoms. The investigation of the CdSe/ZnS core-shell nanocrystals allows us to determine the average thickness of the ZnS shell and to study the interface between the two semiconductor nanomaterials. The photoemission spectra indicate a rather well ordered interface. No evidence for interfacial bonds other than Cd–S and Se–Zn is found.
Quantifying Bacterial Bioburden During Negative Pressure Wound Therapy (2004)

The bacterial colonization of a wound is a recognized detrimental factor in the multifactorial process of wound healing. The harmful effects on wound healing are recognized to correspond to a level of > 10(5) colonies of bacteria per gram of tissue. Negative pressure wound therapy has become an accepted treatment modality for acute and chronic wounds with accelerated healing rates observed. It has been previously reported that this therapy enhances bacterial clearance, which may account for the wound healing effects noted. We retrospectively reviewed 25 patients' charts undergoing Wound VAC (Vacuum Assisted Closure Device; KCI International, San Antonio, TX) therapy with serial quantitative cultures and found that there is not a consistent effect of bacterial clearance with the Wound VAC. Furthermore, bacterial colonization increased significantly with Wound VAC therapy and remained in a range of 10(4)-10(6). Despite this finding, the beneficial effects of this treatment modality on wound healing were noted in most cases.

B7-H1-Induced Apoptosis as a Mechanism of Immune Privilege of Corneal Allografts (2006)

The programmed death-1 (PD-1) costimulatory pathway has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. We investigated the role of this pathway in establishing an immune privilege status of corneal allografts in mice. B7-H1, but not B7-DC or PD-1, was expressed constitutively in the eye, i.e., cornea, iris-ciliary body, and retina. After corneal allografting, PD-1(+)CD4(+) T cells infiltrated and adhered with B7-H1(+) corneal endothelium. Blockade of PD-1 or B7-H1, but not B7-DC, led to accelerated corneal allograft rejection. In B7-H1-expressing corneal allografts, apoptosis of the infiltrating PD-1(+)CD4(+) or CD8(+) T cells was observed, after which there was allograft acceptance. In contrast, B7-H1 blockade suppressed apoptosis of infiltrating PD-1(+) T cells, which led to allograft rejection. In vitro, destruction of corneal endothelial cells by alloreactive T cells was enhanced when the cornea was pretreated with anti-B7-H1 Ab. This is the first demonstration that the constitutive expression of B7-H1 plays a critical role in corneal allograft survival. B7-H1 expressed on corneal endothelial cells maintains long-term acceptance of the corneal allografts by inducing apoptosis of effector T cells within the cornea.
The Development of Aircraft Manufacturing in Australia (1996)

Original powered aircraft manufacturing began in Australia in 1910 when Harold Duigan built a copy of a Wright biplane. This was the first powered and controllable aircraft manufactured in Australia. In 1927 the De Havilland Aircraft Company of the UK., started a plant in Melbourne to manufacture the Moth biplane. The next major manufacturer was a wholly Australian private company, the Commonwealth Aircraft Corporation (CAC), begun in 1936. After them came what was known as the Government Aircraft Factories (GAF), begun in 1939 at the behest of the British War Ministry. De Havillands have since acquired the Commonwealth Aircraft Corporation, and The Government Aircraft Factories evolved into the Government business enterprise Aerospace Technologies of Australia (ASTA), which has recently been sold [to] the American Rockwell Corporation.
Complement activation and immune complexes in juvenile rheumatoid arthritis. (1993)

We investigated the potential role of the complement system in juvenile rheumatoid arthritis (JRA) by examining plasma for levels of complement activation fragments C4d and Bb. We correlated findings with both disease activity and laboratory abnormalities, including immune complex (IC) levels. While there was a strong correlation between active disease and both C4d and Bb plasma levels in JRA, no strong correlations could be made between IC levels and complement activation products; weak associations were seen between complement activation fragments and erythrocyte sedimentation rate. Our data suggest that plasma complement activation is a concomitant of active disease in JRA; however, its role in the pathophysiology of JRA remains uncertain.
169: On the Road to in Situ Tissue Regeneration: A Tissue Engineered Nanofiber Fibrinogen-Polydioxanone Composite Matrix (2007)

spermatogonial stem cells, and for higher purification a magnetic activated cell sorting with cluster of differentiation 49f followed. The isolated cells were transposed into specific established culture mediums and protocols for neuronal, pancreatic, osteogenic and myogenic differentiation of embryonic stem cells were performed. The precursor cells were transplanted in utero and in adult nude mice for testing the potency of the cells.
Peptide receptor imaging and therapy. (2000)

This article reviews the results of somatostatin receptor imaging (SRI) in patients with somatostatin receptor-positive neuroendocrine tumors, such as pituitary tumors, endocrine pancreatic tumors, carcinoids, gastrinomas, and paragangliomas, or other diseases in which somatostatin receptors may also be expressed, like sarcoidosis and autoimmune diseases. [(111)In-DTPA0]octreotide is a radiopharmaceutical that has great potential for helping visualize whether somatostatin receptor-positive tumors have recurred. The overall sensitivity of SRI to localize neuroendocrine tumors is high. In several neuroendocrine tumor types, inclusion of SRI in the localization or staging procedure may be very rewarding in terms of cost effectiveness, patient management, or quality of life. The value of SRI in patients with other tumors, such as breast cancer or malignant lymphomas, or in patients with granulomatous diseases has to be established. The application of radiolabeled peptides may be clinically useful in another way: after the injection of [(111)In-DTPA0]octreotide, surgeons can detect tumor localizations by a probe that is used during the operation. This may be of particular value if small tumors with a high receptor density are present (e.g., gastrinomas). As the success of peptide receptor scintigraphy for tumor visualization became clear, the next logical step was to try to label these peptides with radionuclides emitting alpha or beta particles, or Auger or conversion electrons, and to perform radiotherapy with these radiolabeled peptides. The results of the described studies with 90Y- and (111)In-labeled octreotide show that peptide receptor radionuclide therapy using radionuclides with appropriate particle ranges may become a new treatment modality. One might consider the use of radiolabeled somatostatin analogs first in an adjuvant setting after surgery of somatostatin receptor-positive tumors to eradicate occult metastases and second for cancer treatment at a later stage.
A Probabilistic Representation for Dynamic Movement Primitives (2016)

Dynamic Movement Primitives have successfully been used to realize imitation learning, trial-and-error learning, reinforce- ment learning, movement recognition and segmentation and control. Because of this they have become a popular represen- tation for motor primitives. In this work, we showcase how DMPs can be reformulated as a probabilistic linear dynamical system with control inputs. Through this probabilistic repre- sentation of DMPs, algorithms such as Kalman filtering and smoothing are directly applicable to perform inference on pro- prioceptive sensor measurements during execution. We show that inference in this probabilistic model automatically leads to a feedback term to online modulate the execution of a DMP. Furthermore, we show how inference allows us to measure the likelihood that we are successfully executing a given motion primitive. In this context, we show initial results of using the probabilistic model to detect execution failures on a simulated movement primitive dataset.
[Continuous positive airway pressure (CPAP)--does the equipment live up to its name?]. (1992)

The purpose of this study was to evaluate the in- and expiratory pressures achieved by the use of different continuous positive airway pressure (CPAP) delivery systems. The study was performed on ten healthy adults breathing spontaneously with: 1) "simple CPAP", consisting of a fresh gas flow around 40 l/min and reservoir balloons of 2, 6 and 10 l and expiration against a water column, 2) a high-flow system CR60 CPAP, designed for home treatment and 3) another high-flow system Down's CPAP. Both high-flow systems used a venturi device (Downs Flow Generator, Vital Signs) giving flows around 90 and 170 l/min in our set-up, and the same PEEP valves (Vital signs) were used. All systems were tested with expiratory pressures set at 5, 10 and 20 cm H2O. Individual responses were found, but in general the simple CPAP with a 10 l latex balloon reservoir gave optimal CPAP. The high-flow systems were not found to provide better CPAP, however, CR60 CPAP was found also to be optimal with 5 and 10 cm H2O. Down's CPAP provided 3-5 cm higher expiratory pressure than the intended CPAP level. We recommend measurement of the pressure during the CPAP treatment to ensure that the intended CPAP is achieved.
Chronic electrical stimulation of the ventralis intermedius nucleus of the thalamus as a treatment of movement disorders (1996)

Tremor was suppressed by test stimulation of the thalamic ventralis intermedius (VIM) nucleus at high frequency (130 Hz) during stereotaxy in nonanesthetized patients suffering from Parkinson's disease or essential tremor. Ventralis intermedius stimulation has since been used by the authors over the last 8 years as a treatment in 117 patients with movement disorders (80 cases of Parkinson's disease, 20 cases of essential tremor, and 17 cases of various dyskinesias and dystonias including four multiple sclerosis). Chronic electrodes were stereotactically implanted in the VIM and connected to a programmable stimulator. Results depend on the indication. In Parkinson's disease patients, tremor, but not bradykinesia and rigidity, was selectively suppressed for as long as 8 years. Administration of L-Dopa was decreased by more than 30% in 40 Parkinson's disease patients. In essential tremor patients, results were satisfactory but deteriorated with time in 18.5% of cases, mainly for patients who presented an action component of their but deteriorated with time in 18.5% of cases, mainly for patients who presented an action component of their tremor. In other types of dyskinesias (except multiple sclerosis), results were much less favorable. Fifty-nine patients underwent bilateral implantation and 14 other patients received implantation contralateral to a previous thalamotomy. Thirty-seven patients (31.6%) experienced minor side effects, which were always well tolerated and immediately reversible. Three secondary scalp infections led to temporary removal of the implanted material. There was no permanent morbidity. This tremor suppression effect could be due to the inhibition or jamming of a retroactive loop. Chronic VIM stimulation, which is reversible, adaptable, and well tolerated even by patients undergoing bilateral surgery (74 of 117 patients) and by elderly patients, should replace thalamotomy in the regular surgical treatment of parkinsonian and essential tremors.
Simultaneous Measurements of Mass and Collisional Cross-Section of Single Ions with Charge Detection Mass Spectrometry (2017)

The masses and mobilities of single multiply charged ions of cytochrome c, ubiquitin, myoglobin, and bovine serum albumin formed by electrospray ionization are measured using charge detection mass spectrometry (CDMS). Single ions are trapped and repeatedly measured as they oscillate inside an electrostatic ion trap with cone electrodes for up to the maximum trapping time set at 500 ms. The histograms of the many single ion oscillation frequencies have resolved peaks that correspond to the different charge states of each protein. The m/z of each ion is determined from the initial oscillation frequency histogram, and the evolution of the ion energy with time is obtained from the changing frequency. A short-time Fourier transform of the time-domain data indicates that the increase in ion frequency occurs gradually with time with occasional sudden jumps in frequency. The frequency jumps are similar for each protein and may be caused by collision-induced changes in the ion trajectory. The rate of the gradual frequency shift increases with protein mass and charge state. This gradual frequency change is due to ion energy loss from collisions with the background gas. The total energy lost by an ion is determined from the latter frequency shifts normalized to a 500 ms lifetime, and these values increase nearly linearly with measured collisional cross-sections for these protein ions. These results show that the mass and collisional cross-section of single multiply charged ions can be obtained from these CDMS measurements by using proteins with known collisional cross-sections for calibration.
