A Recombinant Blood‐Stage Malaria Vaccine Reduces Plasmodium falciparum Density and Exerts Selective Pressure on Parasite Populations in a Phase 1–2b Trial in Papua New Guinea (2002)

The malaria vaccine Combination B comprises recombinant Plasmodium falciparum ring-infected erythrocyte surface antigen and 2 merozoite surface proteins (MSP1 and MSP2) formulated in oil-based adjuvant. A phase 1-2b double-blind, randomized, placebo-controlled trial in 120 children (5-9 years old) in Papua New Guinea demonstrated a 62% (95% confidence limits: 13%, 84%) reduction in parasite density in children not pretreated with sulfadoxine-pyrimethamine. Vaccinees had a lower prevalence of parasites carrying the MSP2-3D7 allelic form (corresponding to that in the vaccine) and a higher incidence of morbid episodes associated with FC27-type parasites. These results demonstrate functional activity of Combination B against P. falciparum in individuals with previous malaria exposure. The specific effects on parasites with particular msp2 genotypes suggest that the MSP2 component, at least in part, accounted for the activity. The vaccine-induced selection pressure exerted on the parasites and its consequences for morbidity strongly argue for developing vaccines comprising conserved antigens and/or multiple components covering all important allelic types.
Trop-2 protein overexpression is an independent marker for predicting disease recurrence in endometrioid endometrial carcinoma (2012)

Trop-2 protein overexpression is significantly associated with higher tumor grade and serves as an independent prognostic factor for DFS in endometrioid endometrial cancer.
Angelman syndrome: advancing the research frontier of neurodevelopmental disorders (2010)

This report is a meeting summary of the 2010 Angelman Syndrome Foundation's scientific symposium on the neuroscience of UBE3A. Angelman syndrome is characterized by loss of speech, severe developmental delay, seizures, and ataxia. These core symptoms are caused by maternal allele disruptions of a single gene-UBE3A. UBE3A encodes an E3 ubiquitin ligase that targets certain proteins for proteasomal degradation. This biology has led to the expectation that the identification of Ube3a protein targets will lead to therapies for Angelman syndrome. The recent discovery of Ube3a substrates such as Arc (activity-regulated cytoskeletal protein) provides new insight into the mechanisms underlying the synaptic function and plasticity deficits caused by the loss of Ube3a. In addition to identifying Ube3a substrates, there have also been recent advances in understanding UBE3A's integrated role in the neuronal repertoire of genes and protein interactions. A developmental picture is now emerging whereby UBE3A gene dosage on chromosome 15 alters synaptic function, with deficiencies leading to Angelman syndrome and overexpression associated with classic autism symptomatology.
Oncostatin M and Leukemia Inhibitory Factor Do Not Use the Same Functional Receptor in Mice (1997)

Oncostatin M (OSM) and leukemia inhibitory factor (LIF ) are members of the interleukin-6 (IL-6) subfamily of cytokines that use a common signal transducer gp130. Human OSM (hOSM) and LIF share a functional high-affinity receptor that is composed of gp130 and LIF receptor β subunit (LIFRβ). A second high-affinity receptor for hOSM was recently found to be formed by gp130 and the hOSM receptor β subunit. However, the nature of murine OSM (mOSM) and its receptors has remained unknown. Using the recently cloned mOSM cDNA, we produced recombinant mOSM and studied its biological activity and receptor structure. Murine hematopoietic cell lines M1 and DA1.a, an embryonic stem cell line CCE, and Ba/F3 transfectants expressing gp130 and LIFRβ responded to murine LIF (mLIF ) and hOSM equally well, while these cells responded to mOSM only at a 30-fold to 100-fold higher concentration than those of mLIF and hOSM. In contrast, NIH3T3 cells responded to mOSM, but not to mLIF and hOSM. Scatchard plot analyses showed that mOSM bound to gp130 with low-affinity (kd = 2.8 to 4.2 nmol/L) and that the binding affinity did not increase in the presence of LIFRβ. However, mOSM bound to NIH3T3 cells with high-affinity (kd = 660 pmol/L), whereas mLIF did not bind to NIH3T3 cells at all. These results indicate that unlike hOSM, mOSM and mLIF do not share the same functional receptor, and mOSM delivers signals only through its specific receptor complex. Further studies in mice will define the physiological roles of OSM.
Transforming growth factor-β-like activity in tumors of the central nervous system (1988)

Transforming growth factor type beta (TGF-beta) is a ubiquitous peptide with wide-ranging regulatory functions. This paper reports the initial isolation of TGF-beta activity from human glial and mesenchymally derived tumors and a human glial tumor cell line. While its physiological function at the molecular level is not yet defined, it is believed that this peptide plays a central role in the control of growth and transformation, with the exact role it plays being a function of the entire set of growth factors present in a given cell.
Class Testing from State Diagrams Using Stream X-Machine Based Methods (2007)

The stream X-machine (SXM) is a form of extended finite state machine that describes a system as a finite set of states, an internal memory and a number of transitions between the states. One of the strengths of using a SXM to specify a system is that, under certain well defined conditions, it is possible to produce a test suite that is guaranteed to determine the correctness of the implementation under test. This paper shows how SXM based testing techniques can be applied to generate test suites at class level from state diagrams. Furthermore, a technique for constructing test suites for a hierarchical SXM without flattening the diagram, by reusing the test suites for the components, is given.
Transfer printing: An approach for massively parallel assembly of microscale devices (2008)

Transfer printing is a new technique that enables the massively parallel assembly of high performance semiconductor devices onto virtually any substrate material, including glass, plastics, metals or other semiconductors. This semiconductor transfer printing technology relies on the use of an elastomeric molded stamp to selectively pick-up devices from a source wafer and then prints the devices onto the target substrate. The key enabling technique is the ability to tune the adhesion between the elastomeric stamp and the semiconductor devices. The transfer process is massively parallel as the stamps are designed to transfer thousands of discrete devices in a single pick-up and print operation. Studies of the process yield indicate that print yields in excess of 99.9% can be achieved. In addition, experiments show that the chips can be printed with placement accuracy better than +/- 5 mum.
Ovine Trophoblast Protein 1, an Early Secreted Blastocyst Protein, Binds Specifically to Uterine Endometrium and Affects Protein Synthesis* (1984)

Ovine trophoblastic protein-1 (oTP-1), an early secretory protein of the sheep blastocyst, was purified after culturing day 14-16 conceptuses for 24 h in vitro. The localization of oTP-1 in the pregnant day 16 sheep uterus was determined immunocytochemically. The protein was associated with trophectoderm cells of the elongated blastocyst and with the surface and upper glandular epithelium of the maternal uterus. Receptors that bound oTP-1 with high affinity (Kd = approximately 2 X 10(-10) M) were present in crude membrane preparations derived from homogenates of endometria from day 12 nonpregnant and anestrous ewes. Uterine infusion of 125I-labeled oTP-1 into day 12 nonpregnant ewes showed that the majority of the radioactivity was retained in the uterus, and only very small amounts of intact protein appeared to enter the maternal vasculature. There was no significant association with the corpora lutea, ovaries, or other tissues tested. oTP-1 failed to compete with ovine PRL for rabbit mammary gland receptors or with hCG or bovine LH for sheep luteal cell receptors, and the oTP-1 did not stimulate progesterone production by dispersed luteal cells from day 12 cycling ewes. Incubation of endometrial explants from day 12 nonpregnant ewes with 5 micrograms/ml oTP-1 resulted in increased rates of protein release into the medium. Two-dimensional polyacrylamide gel electrophoresis revealed that the synthesis of six polypeptides was stimulated selectively by the presence of oTP-1. Together these data suggest that oTP-1 acts on the maternal endometrium. It is suggested that the interaction of oTP-1 with uterine endometrium may elicit maternal responses which contribute to the maintenance of pregnancy in the sheep.
Nutritional and pharmacologic support in patients with pancreatic cancer. (2008)

NTS score at initial visit in 44 patients (100%) was > or = 5. Using nutritional counseling, enteral food substitution and pharmacological support, weight gain was observed in 61.1% patients and appetite improved. Average KPS mostly improved after first month of therapy while after two months was again at the basal level. With nutritional counseling, supplemental feeding and pharmacologic support weight loss in our patients slowed down and appetite improved. Despite of that, Karnofsky Performance Status didn't change significantly, reflecting the impact of the disease itself and chemotherapy procedures to the patient's condition. We can conclude that nutritional and pharmacological support can temporarily stop weight loss and improve appetite, social life and quality of life in those groups of patients but have no implications on patients KPS and course of their disease.
Treatment of Skin Papillomas with Topical α-Lactalbumin–Oleic Acid (2004)

Treatment with topical alpha-lactalbumin-oleic acid has a beneficial and lasting effect on skin papillomas.
A covalent and cleavable antibody-DNA conjugation strategy for sensitive protein detection via immuno-PCR (2016)

Immuno-PCR combines specific antibody-based protein detection with the sensitivity of PCR-based quantification through the use of antibody-DNA conjugates. The production of such conjugates depends on the availability of quick and efficient conjugation strategies for the two biomolecules. Here, we present an approach to produce cleavable antibody-DNA conjugates, employing the fast kinetics of the inverse electron-demand Diels-Alder reaction between tetrazine and trans-cyclooctene (TCO). Our strategy consists of three steps. First, antibodies are functionalized with chemically cleavable NHS-s-s-tetrazine. Subsequently, double-stranded DNA is functionalized with TCO by enzymatic addition of N3-dATP and coupling to trans-Cyclooctene-PEG12-Dibenzocyclooctyne (TCO-PEG12-DBCO). Finally, conjugates are quickly and efficiently obtained by mixing the functionalized antibodies and dsDNA at low molar ratios of 1:2. In addition, introduction of a chemically cleavable disulphide linker facilitates release and sensitive detection of the dsDNA after immuno-staining. We show specific and sensitive protein detection in immuno-PCR for human epidermal stem cell markers, ITGA6 and ITGB1, and the differentiation marker Transglutaminase 1 (TGM1). We anticipate that the production of chemically cleavable antibody-DNA conjugates will provide a solid basis for the development of multiplexed immuno-PCR experiments and immuno-sequencing methodologies.
Combining passive haptics with redirected walking (2005)

Two large problems faced by virtual environment designers are lack of haptic feedback and constraints imposed by limited tracker space. Passive haptic feedback has been used effectively to provide a sense of touch to users (Insko, et al., 2001). Redirected walking is a promising solution to the problem of limited tracker space (Razzaque, et al., 2001). However, these solutions to these two problems are typically mutually exclusive because their requirements conflict with one another. We introduce a method by which they can be combined to address both problems simultaneously.
Enhanced Electroluminescence Efficiency in a Spiro‐Acridine Derivative through Thermally Activated Delayed Fluorescence (2012)

Make your OLED fluorescent: an aromatic molecule based on a spiro-acridine derivative was designed, and its photoluminescence and electroluminescence were characterized. By combining the donor and acceptor moieties a small energy gap between the lowest singlet and triplet states was achieved. This design leads to an organic light-emitting diode (OLED) that rivals phosphorescent devices regarding exciton generation efficiency.
A Protective Role for C5a in the Development of Allergic Asthma Associated with Altered Levels of B7-H1 and B7-DC on Plasmacytoid Dendritic Cells (2009)

The role of complement in the development of maladaptive immunity in experimental allergic asthma is unclear. In this study, we show that C3a receptor (C3aR)-deficient mice are protected from the development of Th2 immunity in a model of house dust mite-induced asthma. C5a receptor (C5aR)-targeting of C3aR-deficient mice during allergen sensitization not only reversed the protective effect but enhanced Th2 cytokine production, airway inflammation, and airway responsiveness, suggesting that the reduced allergic phenotype in C3aR-deficient mice results from protective C5aR signaling. In support of this view, C5aR expression in C3aR-deficient pulmonary dendritic cells (DCs) was increased when compared with wild-type DCs. Moreover, C5aR targeting regulated the frequency of pulmonary plasmacytoid DCs expressing costimulatory molecules B7-H1 and B7-DC. Ex vivo targeting of B7-H1 and B7-DC increased Th2 cytokine production from T cells of wild-type but not of C5aR-targeted mice, suggesting a protective role for C5a through regulation of B7 molecule expression on plasmacytoid DCs.
Giant Cell Myocarditis Associated with Silicone: An Unusual Case of Biomaterials Pathology Discovered at Autopsy Using X-Ray Energy Spectroscopic Techniques (1990)

Silicones, used extensively in the fabrication of medical devices because they were presumed inert and biocompatible, are now well-recognized inducers of localized granulomatous inflammation. Silicones less commonly are also associated with more complex clinico-pathologic entities. In this communication, the authors present a case of a patient on chronic hemodialysis involving tubing probably fabricated from silicone rubber who died from a giant cell myocarditis associated with silicone rubber. This case is presented to expand the interpretive paradigm of human pathology and underscores the need for pathologists to consider medical-device associated phenomena in the differential diagnosis of clinical specimens.
Prolonged complete remission of myelodysplastic syndrome treated with danazol, retinoic acid and low-dose prednisone (2000)

Myelodysplastic syndrome (MDS) is a diverse group of clonal hematologic neoplasms. Different medications have been tried in MDS; however, no effective treatment has been yet established. We report a patient with MDS who achieved a complete remission in response to combination therapy of danazol, retinoic acid, and prednisone. A 53-year-old female presented with pancytopenia, macrocytosis, and hypercellular bone marrow with erythroid hyperplasia and dysplasia and 10% ringed sideroblasts. Cytogenetic studies revealed the presence of two abnormal clones. She was diagnosed as having MDS-refractory anemia and was given blood transfusions to maintain blood cell counts at acceptable levels. At the same time, she was started on a combination of danazol (600 mg/day), retinoic acid (100 mg/day), and prednisone (10 mg every other day). Fourteen months later, the patient was in complete hematologic remission; she had normal peripheral blood count, and the blood smear showed normal morphology. Bone marrow studies revealed normal trilineage hematopoiesis. She was continued on the same combination treatment for 86 months, and she remained in complete clinical remission. Eighty-eight months from diagnosis, she relapsed with acute myeloid leukemia. This is the first reported case of MDS-RA that sustained a complete hematologic remission for a prolonged period in response to this combination treatment. This report indicates that restoration of normal hematopoiesis, prolongation of disease-free survival, and delay in the transformation to acute leukemia may be achieved by this combination of treatment in a subset of patients with MDS, especially refractory anemia with severe thrombocytopenia.

K‐252b Is a Selective and Nontoxic Inhibitor of Nerve Growth Factor Action on Cultured Brain Neurons (1991)

K-252b is a kinase inhibitor structurally related to K-252a, which is known to abolish selectively the effects of nerve growth factor (NGF) on PC12 cells and PNS neurons. We tested whether K-252b, K-252a, and staurosporine, another related compound, are effective and selective inhibitors of NGF actions on CNS neurons. All three compounds, at appropriate concentrations, completely and selectively prevented the NGF-mediated activity increase of the cholinergic marker enzyme choline acetyltransferase in cultures of rat basal forebrain cells. The stimulatory effects of basic fibroblast growth factor and insulin on choline acetyltransferase in these cultures and on dopamine uptake in cultures of dissociated ventral mesencephalon were not affected. No signs of toxicity were observed in cultures treated with K-252b. In contrast, K-252a and staurosporine, at concentrations required to block the NGF actions on cholinergic cells, were cytotoxic and produced cell loss. In addition, K-252a, at higher concentrations and in the absence of growth factors, increased cell numbers. Our study suggests that K-252b is a selective and nontoxic inhibitor of NGF actions in the brain and may become a useful tool to study these actions in vivo.
Up-Regulation of Vascular Endothelial Growth Factor-D Expression in Clear Cell Renal Cell Carcinoma by CD74: A Critical Role in Cancer Cell Tumorigenesis (2008)

Elevation of CD74 is associated with a number of human cancers, including clear cell renal cell carcinoma (ccRCC). To understand the role of CD74 in the oncogenic process of ccRCC, we ectopically expressed CD74 in human embryonic kidney 293 cells (HEK/CD74) and evaluated its oncogenic potential. Through overexpression of CD74 in HEK293 and Caki-2 cells and down-regulation of CD74 in Caki-1 cells, we show that vascular endothelial growth factor-D (VEGF-D) expression is modified accordingly. A significant, positive correlation between CD74 and VEGF-D is found in human ccRCC tissues (Pearson's correlation, r = 0.65, p < 0.001). In HEK/CD74 xenograft mice, CD74 significantly induced the formation of tumor masses, increased tumor-induced angiogenesis, and promoted cancer cell metastasis. Blockage of VEGF-D expression by small interference RNA resulted in a decrease in cell proliferation, invasion, and cancer cell-induced HUVEC migration enhanced by CD74. Furthermore, we provide evidence that the intracellular signaling cascade responsible for VEGF-D up-regulation by CD74 is both PI3K/AKT- and MEK/ERK-dependent, both of which are associated with NF-kappaB nuclear translocation and DNA-binding activity. These results suggest that VEGF-D is crucial for CD74-induced human renal carcinoma cancer cell tumorigenesis.
PCR Detection of Acute Ehrlichia Canis Infection in Dogs (1996)

A polymerase chain reaction (PCR)-based detection assay that specifically detected Ehrlichia canis in dogs with acute infections was developed. A region of the 16S ribosomal RNA gene of E. canis was targeted for PCR amplification and chemiluminescent hybridization (CH) with a complementary internal 287-base pair (bp) oligonucleotide probe. The CH improved the PCR assay sensitivity 1,000-fold as compared with visualization on ethidium bromide-stained agarose gels. The PCR assay with CH (PCR/CH) detected as little as 30 fg of E. canis genomic DNA, the equivalent of approximately 150 E. canis organisms. The 495-bp product defined by the specific primers was not detected when genomic DNA from E. platys, E. chaffeensis, E. risticii, and E. equi were used in the PCR/CH assay. The PCR/CH assay was tested with unfractionated blood samples collected from 9 dogs experimentally infected with E. canis. The PCR/CH assay had greater detection sensitivity than did cell culture isolation (CCI) from infected blood. PCR/CH detected E. canis 7 days prior to CCI in 4 of 6 experimentally infected dogs. The results obtained with the PCR/CH assay otherwise consistently matched the results obtained by CCI. This PCR/CH assay is a rapid, sensitive, and specific method for E. canis detection with sensitivity comparable to or exceeding that of CCI. A diagnosis of E. canis using this PCR/CH assay can be made in 2 days as compared with 1-4 weeks for CCI. The PCR/CH assay appears to be an acceptable alternative or complement to current diagnostic techniques.
Human immunoglobulin heavy chain genes: evolutionary comparisons of Cμ, Cδ and Cγ genes and associated switch sequences (1981)

Human immunoglobulin heavy chain constant region genes have been characterised in isolated clones. The human c mu gene comprises discrete domains for C mu 1, C mu 2, C mu 3 and C mu 4 + tp separated by short intervening sequences. The C delta gene has been located about 5 kb downstream of C mu 4. Furthermore, the coding segments for the membrane form of mu have been located 1.9 kb downstream of C mu 4. Tandemly repeated sequences implicated in the heavy chain class switch occur upstream of the C mu and the C gamma genes, but none were detected near the C delta gene. These tandem repeats are very homologous to those of mouse. Particularly common is the sequence G-A-G-C-T. These data suggest that the mu to gamma switch in humans involves DNA rearrangements of the CH-genes and subsequent deletion of DNA, but that the coexpression of C mu and C delta genes results from different mechanisms.
Uncoupling in the expression of platelet GP IIb/IIIa in human endothelial cells and K562 cells: absence of immunologic crossreactivity between platelet GP IIb and the vitronectin receptor alpha chain [see comments] (1988)

Platelet glycoproteins (GP) IIb and IIIa exist as noncovalently associated Ca++-dependent heterodimer complexes within the platelet membrane and express the major platelet alloantigens Leka (Baka) and PIA1 (Zwa), which are genetic markers of GP IIb and GP IIIa, respectively. Since heterodimers immunologically related to platelet GP IIb/IIIa have been identified in a number of nucleated cell types, we tested anti-Leka and anti-PIA1 antiserum, polyclonal anti-platelet GP IIb/IIIa IgG, as well as a panel of 28 monoclonal anti-GP IIb, GP IIIa, or complex dependent anti-GP IIb/IIIa antibodies on endothelial cells, peripheral blood mononuclear cells, and the erythroleukemic cells HEL and K562 in order to determine whether nucleated cell GP IIb/IIIa related proteins and platelet GP IIb/IIIa are immunologically related. Using immunofluorescence, immunoblotting, and immunoprecipitation experiments, evidence is presented that (1) the alloantigen Leka is not expressed in endothelial cells of an individual whose platelets are of the Leka/PIA1 phenotype, whereas the PIA1 alloantigen is readily detectable in these cells, (2) that in contrast to HEL cells, which express platelet GP IIb/IIIa and are of the Leka/PIA1 phenotype, platelet GP IIb is immunologically undetectable in 12-O-tetradecanoyl- phorbol-13-acetate (TPA)-treated K562 cells despite the presence of platelet GP IIIa, and (3) that peripheral blood mononuclear cells do not express platelet GP IIb or GP IIIa on their cell surface.
