Capture PCR: An Efficient Method for Walking Along Chromosomal DNA and cDNA (1994)

The polymerase chain reaction (PCR) is an enzymatic process that allows the generation of millions of identical DNA molecules in vitro in a few hours, starting with as little as one copy of DNA (Mullis et al., 1986; Mullis and Faloona, 1987; Saiki et al., 1988). In contrast to conventional cloning, this in vitro amplification process is quick, efficient, and can easily be automated. In addition to its enormous potential for clinical diagnosis PCR has found numerous applications in all fields of biology and medicine (Innis et al., 1990; Erlich, 1989; Erlich etal., 1991).

The coming of age of virus-like particle vaccines (2008)

Virus-like particles are supra-molecular assemblages, usually icosahedral or rod-like structures. They incorporate key immunologic features of viruses which include repetitive surfaces, particulate structures and induction of innate immunity through activation of pathogen-associated molecular-pattern recognition receptors. They carry no replicative genetic information and can be produced recombinantly in large scale. Virus-like particles thus represent a safe and effective vaccine platform for inducing potent B- and T-cell responses. In addition to being effective vaccines against the corresponding virus from which they are derived, virus-like particles can also be used to present foreign epitopes to the immune system. This can be achieved by genetic fusion or chemical conjugation. This technological innovation has greatly broadened the scope of their use, from immunizing against microbial pathogens to immunotherapy for chronic diseases. Towards this end, virus-like particles have been used to induce autoantibodies to disease-associated self-molecules involved in chronic diseases, such as hypertension and Alzheimer's disease. The recognition of the potent immunogenicity and commercial potential for virus-like particles has greatly accelerated research and development activities. During the last decade, two prophylactic virus-like particle vaccines have been registered for human use, while another 12 vaccines entered clinical development.
Diverse transposable elements are mobilized in hybrid dysgenesis in Drosophila virilis. (1995)

We describe a system of hybrid dysgenesis in Drosophila virilis in which at least four unrelated transposable elements are all mobilized following a dysgenic cross. The data are largely consistent with the superposition of at least three different systems of hybrid dysgenesis, each repressing a different transposable element, which break down following the hybrid cross, possibly because they share a common pathway in the host. The data are also consistent with a mechanism in which mobilization of a single element triggers that of others, perhaps through chromosome breakage. The mobilization of multiple, unrelated elements in hybrid dysgenesis is reminiscent of McClintock's evidence [McClintock, B. (1955) Brookhaven Symp. Biol. 8, 58-74] for simultaneous mobilization of different transposable elements in maize.
Subcontract (1993)

A key problem in operating systems is permitting the orderly introduction of new properties and new implementation techniques. We describe a mechanism, subcontract, that within the context of an object-oriented distributed system permits application programmers control over fundamental object mechanisms. This allows programmers to define new object communication mechanisms without modifying the base system. We describe how new subcontracts can be introduced as alternative communication mechanisms in the place of existing subcontracts. We also briefly describe some of the uses we have made of the subcontract mechanism to support caching, crash recovery, and replication.
Principles of antibody-mediated TNF receptor activation (2015)

From the beginning of research on receptors of the tumor necrosis factor (TNF) receptor superfamily (TNFRSF), agonistic antibodies have been used to stimulate TNFRSF receptors in vitro and in vivo. Indeed, CD95, one of the first cloned TNFRSF receptors, was solely identified as the target of cell death-inducing antibodies. Early on, it became evident from in vitro studies that valency and Fcγ receptor (FcγR) binding of antibodies targeting TNFRSF receptors can be of crucial relevance for agonistic activity. TNFRSF receptor-specific antibodies of the IgM subclass and secondary cross-linked or aggregation prone dimeric antibodies typically display superior agonistic activity compared with dimeric antibodies. Likewise, anchoring of antibodies to cell surface-expressed FcγRs potentiate their ability to trigger TNFRSF receptor signaling. However, only recently has the relevance of oligomerization and FcγR binding for the in vivo activity of antibody-induced TNFRSF receptor activation been straightforwardly demonstrated in vivo. This review discusses the crucial role of oligomerization and/or FcγR binding for antibody-mediated TNFRSF receptor stimulation in light of current models of TNFRSF receptor activation and especially the overwhelming relevance of these issues for the rational development of therapeutic TNFRSF receptor-targeting antibodies.
Regeneration versus neoplastic growth (1997)

Amphibian tissues seem to resist oncogenesis in proportion to their regenerative capacity, a phenomenon most easily seen in relation to limb regeneration. There is evidence that mammalian tissues also possess, in addition to and distinct from the capacity for physiological renewal, a limited and not always overtly evident degree of amphibian-like capacity for regeneration (epimorphic regeneration). It is the thesis of this paper that cancer in mammals would seldom occur were it not for a local destruction or exhaustion, secondary to injury or aging, of this normal amphibian-like regenerative capacity.
α-synuclein and tyrosine hydroxylase expression in acute rotenone toxicity (2007)

Chronic low-dose (2-3 mg/kg/day) rotenone infusion produces clinical features and biological markers of Parkinson's disease (PD) in some rats. A significant proportion of rats, however, die of acute rotenone toxicity. Most studies have focused on chronic rotenone-infused rats. It has not been established if the animals that die of acute low-dose rotenone toxicity manifest clinical or pathological evidence of PD. In the present study, six rats that received continuous 3 mg/kg/day subcutaneous rotenone infusion, became moribund and were euthanized after five days were compared with ten vehicle infused animals sacrificed 14, 28 or 56 days after placebo infusion. All rotenone-infused rats had significant motor function decline beginning one day after the infusion and progressive worsening in the physical condition until they became severely akinetic, at which point they were euthanized. In the substantia nigra of rotenone-treated rats, four of six had reduced numbers of tyrosine hydroxylase-positive neurons and all six had increased nigral alpha-synuclein expression. Our observations show that even a short duration of low-dose subcutaneous rotenone infusion can induce clinical and pathological markers of PD in some rats. The pathophysiology of the enhanced susceptibility to PD in some animals remains to be established.
Dynamic 3-D Virtual Fixtures for Minimally Invasive Beating Heart Procedures (2008)

Two-dimensional or 3-D visual guidance is often used for minimally invasive cardiac surgery and diagnosis. This visual guidance suffers from several drawbacks such as limited field of view, loss of signal from time to time, and in some cases, difficulty of interpretation. These limitations become more evident in beating-heart procedures when the surgeon has to perform a surgical procedure in the presence of heart motion. In this paper, we propose dynamic 3-D virtual fixtures (DVFs) to augment the visual guidance system with haptic feedback, to provide the surgeon with more helpful guidance by constraining the surgeon's hand motions thereby protecting sensitive structures. DVFs can be generated from preoperative dynamic magnetic resonance (MR) or computed tomograph (CT) images and then mapped to the patient during surgery. We have validated the feasibility of the proposed method on several simulated surgical tasks using a volunteer's cardiac image dataset. Validation results show that the integration of visual and haptic guidance can permit a user to perform surgical tasks more easily and with reduced error rate. We believe this is the first work presented in the field of virtual fixtures that explicitly considers heart motion.
Selective chemokine mRNA accumulation in the rat spinal cord after contusion injury (1998)

Following traumatic injury to the spinal cord, hematogenous inflammatory cells including neutrophils, monocytes, and lymphocytes infiltrate the lesion in a distinct temporal sequence. To examine potential mechanisms for their recruitment, we measured chemokine mRNAs in the contused rat spinal cord, using specific and sensitive reverse transcriptase polymerase chain reaction (RT-PCR) dot-blot hybridization assays. The neutrophil chemoattractant GRO-alpha was 30-fold higher than control values at 6 hr postinjury and decayed rapidly thereafter. LIX, a highly related alpha-chemokine, also was elevated early postinjury. Monocyte chemoattractant peptide (MCP)-1 and MCP-5 mRNAs, potent chemoattractants for monocytes, were significantly elevated at the lesion epicenter at 12 and 24 hr postinjury and declined thereafter. Interferon-gamma-inducible protein, 10 kDa (IP-10), chemoattractant towards activated T-lymphocytes, was significantly elevated at 6 and 12 hr postinjury. The dendritic cell chemoattractant MIP-3alpha also was increased, perhaps contributing to the development of T-cell autoreactivity to neural components after spinal cord injury (SCI) in rats. Other beta-chemokines, including MIP-1alpha and RANTES (regulated on expression normal T-cell expressed and secreted), were minimally affected by SCI. Expression of chemokines, therefore, directly precedes the influx of target neutrophils, monocytes, and T-cells into the spinal cord postinjury, as noted previously. Thus, selective chemokine expression may be integral to inflammatory processes within the injured spinal cord as a mechanism of recruitment for circulating leukocytes.
A vaccinia virus renaissance (2012)

In 1796, Edward Jenner introduced the concept of vaccination with cowpox virus, an Orthopoxvirus within the family Poxviridae that elicits cross protective immunity against related orthopoxviruses, including smallpox virus (variola virus). Over time, vaccinia virus (VACV) replaced cowpox virus as the smallpox vaccine, and vaccination efforts eventually led to the successful global eradication of smallpox in 1979. VACV has many characteristics that make it an excellent vaccine and that were crucial for the successful eradication of smallpox, including (1) its exceptional thermal stability (a very important but uncommon characteristic in live vaccines), (2) its ability to elicit strong humoral and cell-mediated immune responses, (3) the fact that it is easy to propagate, and (4) that it is not oncogenic, given that VACV replication occurs exclusively within the host cell cytoplasm and there is no evidence that the viral genome integrates into the host genome. Since the eradication of smallpox, VACV has experienced a renaissance of interest as a viral vector for the development of recombinant vaccines, immunotherapies, and oncolytic therapies, as well as the development of next-generation smallpox vaccines. This revival is mainly due to the successful use and extensive characterization of VACV as a vaccine during the smallpox eradication campaign, along with the ability to genetically manipulate its large dsDNA genome while retaining infectivity and immunogenicity, its wide mammalian host range, and its natural tropism for tumor cells that allows its use as an oncolytic vector. This review provides an overview of new uses of VACV that are currently being explored for the development of vaccines, immunotherapeutics, and oncolytic virotherapies.
Work Function Adjustment by Using Dipole Engineering for TaN-Al2O3-Si3N4-HfSiOx-Silicon Nonvolatile Memory (2015)

This paper presents a novel TaN-Al₂O₃-HfSiO<sub>x</sub>-SiO₂-silicon (TAHOS) nonvolatile memory (NVM) design with dipole engineering at the HfSiO<sub>x</sub>/SiO₂ interface. The threshold voltage shift achieved by using dipole engineering could enable work function adjustment for NVM devices. The dipole layer at the tunnel oxide-charge storage layer interface increases the programming speed and provides satisfactory retention. This NVM device has a high program/erase (P/E) speed; a 2-V memory window can be achieved by applying 16 V for 10 μs. Regarding high-temperature retention characteristics, 62% of the initial memory window was maintained after 10³ P/E-cycle stress in a 10-year simulation. This paper discusses the performance improvement enabled by using dipole layer engineering in the TAHOS NVM.
Abnormal GABAAReceptor-Mediated Currents in Dorsal Root Ganglion Neurons Isolated from Na–K–2Cl Cotransporter Null Mice (2000)

We have recently disrupted Slc12a2, the gene encoding the secretory Na-K-2Cl cotransporter in mice (NKCC1) (Delpire et al., 1999). Gramicidin perforated-patch and whole-cell recordings were performed to study GABA-induced currents in dorsal root ganglion (DRG) neurons isolated from wild-type and homozygote NKCC1 knock-out mice. In wild-type DRG neurons, strong GABA-evoked inward current was observed at the resting membrane potential, suggesting active accumulation of Cl(-) in these cells. This GABA-induced current was blocked by picrotoxin, a GABA(A) receptor blocker. The strong Cl(-) accumulation that gives rise to depolarizing GABA responses is caused by Na-K-2Cl cotransport because reduction of external Cl(-) or application of bumetanide induced a decrease in [Cl(-)](i), whereas an increase in external K(+) caused an apparent [Cl(-)](i) accumulation. In contrast to control neurons, little or no net current was observed at the resting membrane potential in homozygote NKCC1 mutant DRG neurons. E(GABA) was significantly more negative, demonstrating the absence of Cl(-) accumulation in these cells. Application of bumetanide induced a positive shift of E(GABA), suggesting the presence of an outward Cl(-) transport mechanism. In agreement with an absence of GABA depolarization in DRG neurons, behavioral analysis revealed significant alterations in locomotion and pain perception in the knock-out mouse. Our results clearly demonstrate that the Na-K-2Cl cotransporter is responsible for [Cl(-)](i) accumulation in DRG neurons and that via regulation of intracellular Cl(-), the Na-K-2Cl cotransporter participates in the modulation of GABA neurotransmission and sensory perception.
Efficient rainbow color luminescence from InxGa1−xN single quantum wells fabricated on {112¯2} microfacets (2005)

Rainbow color luminescence from InxGa1−xN single quantum wells (SQWs) is achieved and almost covers the entire visible range when the layers are fabricated on {112¯2} facets with a few micron-width using a regrowth technique on striped GaN templates. These facets are tilted 56° with respect to the (0001) facets and border the (0001) and {112¯0} facets. The emission wavelength on the {112¯2} facets is redshifted from the {112¯0} side to (0001) side due to the variations of the In composition, which leads to the color contrast with the rainbow geometry. The temperature dependence of the photoluminescence intensity shows that the internal quantum efficiency at room temperature is 33% due to the very small internal electric fields and a small threading dislocation density compared to that in conventional (0001) InxGa1−xN SQWs. Since the emission efficiency does not show a noticeable emission wavelength dependence, this type of structure has potential as light-emitting devices with multiwavelengths that perform numerous color controllability such as pastel and white colors.
Hyperlipidemia in Coronary Heart Disease I. LIPID LEVELS IN 500 SURVIVORS OF MYOCARDIAL INFARCTION (1973)

Plasma cholesterol and triglyceride levels were measured after an overnight fast in 500 consecutively studied 3-mo survivors of myocardial infarction. Virtually all patients under 60 yr of age (95% ascertainment) and a randomly chosen group of older survivors admitted to 13 Seattle hospitals during an 11 mo period were included. A comparison of their lipid values with those of 950 controls demonstrated that 31% had hyperlipidemia. These lipid abnormalities were most commonly found in males under 40 yr of age (60% frequency) and in females under 50 yr of age (60% frequency). Elevation in triglyceride levels with (7.8%) or without (15.6%) an associated elevation in cholesterol levels was three times more common in survivors than a high cholesterol level alone (7.6%). These results raise the possibility that hypertriglyceridemia may be as an important a risk factor for coronary atherosclerosis as hypercholesterolemia. The identification of hyperlipidemic survivors of myocardial infarction provided a unique source of probands for family studies designed to disclose the genetic origin of hyperlipidemia in coronary heart disease.

Intraocular Hemorrhage Causes Retinal Vascular Dysfunction via Plasma Kallikrein (2013)

Intraocular hemorrhage increases retinal vascular permeability and leukostasis, and these responses are mediated, in part, via PK. Intravitreal injections of either PK or collagenase, but not bradykinin, induce retinal hemorrhage in rats. PK exerts collagenase-like activity that may contribute to blood-retinal barrier dysfunction.
[Development of new approaches to standartization of enzyme immunoassay test systems for detection of antibodies to respiratory syncytial virus using electron microscopy and monoclonal antibodies]. (2000)

Respiratory syncytial virus (RSV), strain Long, was purified through 20-60% sucrose gradient. The virions from different sucrose density zones were tested by ELISA for reactivity with monoclonal antibodies (MAB) to F- (MAB 9C5) and N- (MAB 8B10) proteins of RSV. Comparative study of the same patterns of RSV by electron microscopy after negative staining showed a close relationship between the virion morphology and MAB binding in ELISA. MAB 9C5 were highly reactive with the surface domains of both mature RSV virions and "empty" virion envelopes without formed inner nucleocapsid structures. MAB 8B10 reacted well only with mature virions with completely assembled nucleocapsids. These MAB failed to reorganize the N-protein epitope of immature and destroyed virions, which indicated a conformation dependence of the 8B10 binding site. For practical purposes, MAB tests can be used to determine the RSV patterns, which can be used in ELISA for serologic diagnosis of RSV infection. Testing with these MAB demonstrate the stability of RSV to extreme exposures (lyophilization, storage, heating), which is important for creation of sensitive ELISA test systems and their standardization.
The Spectrum of Serious Infections Among Patients Receiving Immune Checkpoint Blockade for the Treatment of Melanoma (2016)

The risk of infection among patients receiving immune checkpoint blockade is unknown. We retrospectively reviewed medical records of 740 patients with melanoma who received immune checkpoint blockers. Serious infection occurred in 54 patients (7.3%). The main risk factors were receipt of corticosteroids and/or infliximab.
Effects of levocetirizine as add‐on therapy to fluticasone in seasonal allergic rhinitis (2006)

Contrary to current practice, the present results demonstrate that for the majority of patients, antihistamine add-on to effective nasal steroid treatment is inappropriate. Further work is required to confirm that this is also true in the most severe cases, and the available evidence needs to be put into guidelines and implemented.
Serine Phosphorylation-dependent Association of the Band 4.1-related Protein-tyrosine Phosphatase PTPH1 with 14-3-3 Protein (1997)

PTPH1 is a human protein-tyrosine phosphatase with homology to the band 4.1 superfamily of cytoskeletal-associated proteins. PTPH1 was found to associate with 14-3-3beta using a yeast two-hybrid screen, and its interaction could be reconstituted in vitro using recombinant proteins. Examination of the interaction between 14-3-3beta and various deletion mutants of PTPH1 by two-hybrid tests suggested that the integrity of the PTP is important for this binding. Although both PTPH1 and Raf-1 form complexes with 14-3-3beta, they appear to do so independently. Binding of 14-3-3beta to PTPH1 in vitro was abolished by pretreating PTPH1 with potato acid phosphatase and was greatly enhanced by pretreating with Cdc25C-associated protein kinase. Thus the association between PTPH1 and 14-3-3beta is phosphorylation-dependent. Two novel motifs RSLS359VE and RVDS853EP in PTPH1 were identified as major 14-3-3beta-binding sites, both of which are distinct from the consensus binding motif RSXSXP recently found in Raf-1. Mutation of Ser359 and Ser853 to alanine significantly reduced the association between 14-3-3beta and PTPH1. Furthermore, association of PTPH1 and 14-3-3beta was detected in several cell lines and was regulated in response to extracellular signals. These results raise the possibility that 14-3-3beta may function as an adaptor molecule in the regulation of PTPH1 and may provide a link between serine/threonine and tyrosine phosphorylation-dependent signaling pathways.
