Fetal fibronectin: a method for detecting the presence of amniotic fluid. (1992)

Fetal fibronectin is a sensitive test for detection of AF in the vagina and compares favorably to standard tests. Its low specificity suggests that the assay may detect an alteration in membrane integrity. In addition, in patients without rupture of the membranes, the interval between sampling and delivery is significantly shorter if fetal fibronectin is present. We speculate that the presence of fetal fibronectin in cervicovaginal secretions may be a marker for impending labor in gravidas without gross rupture of the membranes.

Can genetic testing guide the therapy of cholestatic pruritus? A case of benign recurrent intrahepatic cholestasis type 2 with severe nasobiliary drainage‐refractory itch (2018)

Benign recurrent intrahepatic cholestasis (BRIC) is a peculiar familial disease caused by mutations of the genes encoding hepatocanalicular flippase for phosphatidylserine (ATP8B1; BRIC type 1) or the bile salt export pump (ABCB11; BRIC type 2). Here, we report on a patient with nasobiliary drainage-refractory BRIC type 2 who improved under plasma separation and anion absorption therapy. We also suggest that nasobiliary drainage might be an ineffective approach in carriers of severe loss-of-function mutations of the bile salt export pump ABCB11. (<i>Hepatology Communications</i> 2018;2:152-154).
Clinical manifestations of atherosclerosis in an elderly population are related to plasma neopterin, NGAL and endothelin-1, but not to Chlamydia pneumoniae serology. (2002)

The inflammatory mediators neopterin and NGAL and endothelial derived vasoconstrictive ET-1 were increased in elderly subjects with symptomatic cardiovascular disease. Increased plasma neopterin predicted cardiovascular disease during follow-up. No relationships were found between C. Pneumoniae serology and cardiovascular disease.
Intercellular adhesion molecule-1 (ICAM-1) gene polymorphisms in endometriosis (2003)

Endometriosis is a gynaecological disease with a certain genetic background, but the locations of possible genomic aberrations are still poorly clarified. Intercellular adhesion molecule-1 (ICAM-1), which is a surface glycoprotein that promotes adhesion in immunological and inflammatory reactions, seems to play a role in this condition. The aim of this study was to examine the potential associations of ICAM-1 gene polymorphisms with endometriosis and its severity. Specifically, we have studied two polymorphic sites located in codons 241 (G/R241) and 469 (E/K469) of the ICAM-1 gene. Three hundred and sixty-three Italian Caucasian women of reproductive age who underwent laparoscopy for benign pelvic conditions were enrolled in the study. Endometriosis was documented and staged in 188 women while 175 subjects, in whom endometriosis was laparoscopically ruled out, served as the control group. The frequency of the R241 allele was only marginally higher in endometriosis patients than in controls [5.8 versus 2.9%, P = 0.05; odds ratio (OR), 2.1; 95% confidence interval (CI), 1-4.5]. However, a strikingly high frequency of this allele was found in patients with Stage IV endometriosis versus controls (8.6 versus 2.8%, P = 0.008; OR, 3.2; 95% CI, 1.3-7.9). In contrast, the allele and genotype frequencies of the E/K469 polymorphism did not differ significantly between endometriosis and control groups. While the functional correlate of the G/R241 polymorphism remains unclear, this finding indicates that a genetic polymorphism in the ICAM-1 gene domain may contribute to the susceptibility to endometriosis.
Structure of the Human Chromosomal Gene for the 25 Kilodalton Insulin-Like Growth Factor Binding Protein (1989)

We have characterized the structure of the human chromosomal gene for the 25 kilodalton insulin-like growth factor binding protein (BP-25) as a first step toward understanding both the factors which regulate BP-25 transcription and also the evolution of the insulin-like growth factor binding proteins. The BP-25 gene is present in the human genome as a single copy which spans 5.2 kilobases and contains four exons. Primer extension localizes the mRNA cap site 165 base pairs (bp) upstream of the ATG translational start codon. Preliminary analysis of the putative promoter region for BP-25 demonstrates characteristics consistent with those of many eukaryotic promoters; these include a consensus TATA box beginning 28 bp 5' to the cap site and a consensus CCAAT promoter element beginning 72 bp upstream from the cap site.
Effects of grapefruit juice on the pharmacokinetics of sildenafil (2002)

Grapefruit juice increases sildenafil bioavailability and tends to delay sildenafil absorption. Sildenafil pharmacokinetics may become less predictable with grapefruit juice. Although patients usually will not be endangered by concomitant use of grapefruit juice, it seems advisable to avoid this combination.

Inducible production of c-fos antisense RNA inhibits 3T3 cell proliferation. (1986)

Antisense RNA complementary to c-fos mRNA was produced in mouse 3T3 cells by gene transfer techniques. Transcriptional units were constructed consisting of a steroid-inducible mouse mammary tumor virus (MMTV) promoter, mouse or human 5' c-fos gene fragments in either the sense (5' to 3') or antisense (3' to 5') orientation, and splice and poly(A) signals from the human beta-globin gene. A gene that confers neomycin resistance was included in the vectors to allow isolation of stable transformants. Dexamethasone caused a marked induction of hybrid MMTV-fos-globin RNA. Induction of the hybrid transcript containing antisense c-fos RNA decreased colony formation following DNA transfer and inhibited the proliferation of cells into which the antisense transcriptional unit had been integrated. In contrast, colony formation and cell proliferation were not inhibited by induction of hybrid RNA containing c-fos RNA sequences in the sense orientation. These results indicate that the strategy of generating antisense RNA to inhibit gene expression may be useful in delineating the function of protooncogenes. The c-fos gene product appears to have a required role in normal cell division.
A Unified Framework for Regularization Networks and Support Vector Machines (1999)

Regularization Networks and Support Vector Machines are techniques for solving certain problems of learning from examples -- in particular the regression problem of approximating a multivariate function from sparse data. We present both formulations in a unified framework, namely in the context of Vapnik&amp;apos;s theory of statistical learning which provides a general foundation for the learning problem, combining functional analysis and statistics.
Alteration of Gene Expression Associated with Abscisic Acid-Induced Chilling Tolerance in Maize Suspension-Cultured Cells (1993)

ABA induces chilling tolerance in maize (Zea mays L., cv Black Mexican Sweet) suspension-cultured cells at 28[deg] C when ABA was added to the culture medium at least 6 h prior to chilling (4[deg] C), and this induction can be inhibited by blocking protein synthesis with cycloheximide treatment (Z. Xin, P.H. Li [1992] Plant Physiol 99: 707-711). De novo synthesis of proteins and changes in poly(A+) RNAs were investigated during the ABA induction of chilling tolerance at 28[deg] C as well as during chilling exposure. At 28[deg] C, ABA increased the net synthesis of 11 proteins. Five of these proteins, whose net synthesis was also increased by chilling (4[deg] C), were called group I ABA-induced proteins; the remaining six proteins, whose net synthesis was not altered by chilling, were called group II ABA-induced proteins. Chilling suppressed the net synthesis of three proteins. ABA treatment prior to chilling did not alleviate this suppression. ABA applied at the inception of chilling induced neither chilling tolerance nor accumulation of any of the group II proteins; however, once the group II proteins appeared, they were continually synthesized even in a chilling regimen. ABA induced seven in vitro translation products at 28[deg] C. Three of these products could also be induced by chilling; the remaining four were induced by ABA only at 28[deg] C. These results suggest that ABA-induced alteration of protein synthesis at 28[deg] C is associated with an increased chilling tolerance in maize suspension-cultured cells.
PRODORIC (release 2009): a database and tool platform for the analysis of gene regulation in prokaryotes (2008)

PRODORIC is a database that provides annotated information on the regulation of gene expression in prokaryotes. It integrates a large compilation of gene regulatory data including transcription factor binding sites, promoter structures and gene expression patterns. The whole dataset is manually curated and relies on published results extracted from the scientific literature. The current extended version of PRODORIC contains gene regulatory data for several new microorganisms. Major improvements were realized in the design of the web interface and the accessibility of the stored information. The database was further improved by the implementation of various new tools for the elucidation of gene regulatory interactions. Thus, the PRODORIC platform represents a framework for the interactive exploration, prediction and evaluation of gene regulatory networks in prokaryotes. PRODORIC is accessible at http://www.prodoric.de.
Disaggregation of home energy display data using probabilistic approach (2012)

Home energy displays are emerging home energy management devices. Their energy saving potential is limited, because most display whole-home electricity consumption data. We propose a new approach to disaggregation electricity consumption by individual appliances and/or end uses that would enhance the effectiveness of home energy displays. The proposed method decomposes a system of appliance models into tuplets of appliances overlapping in power draw. Each tuplet is disaggregated using a modified Viterbi algorithm. In this way, the complexity of the disaggregation algorithm is linearly proportional to the number of appliances. The superior accuracy of the method is illustrated by a simulation example and by actual household data.
An investigation of incorporation of cellular antigens into vaccinia virus particles (2002)

Vaccinia virus (VV) infection produces several types of virus particle called intracellular mature virus (IMV), intracellular enveloped virus (IEV), cell-associated enveloped virus (CEV) and extracellular enveloped virus (EEV). Some cellular antigens are associated with EEV and these vary with the cell type used to grow the virus. To investigate if specific cell antigens are associated with VV particles, and to address the origin of membranes used to envelope IMV and IEV/CEV/EEV, we have studied whether cell antigens and foreign antigens expressed by recombinant VVs are incorporated into VV particles. Membrane proteins that are incorporated into the endoplasmic reticulum (ER), intermediate compartment (IC), cis / medial -Golgi, trans -Golgi network (TGN) or plasma membrane were not detected in purified IMV particles. In contrast, proteins present in the TGN or membrane compartments further downstream in the exocytic pathway co-purify with EEV particles when analysed by immunoblotting. Immunoelectron microscopy found only low levels of these proteins in IEV, CEV/EEV. The incorporation of foreign antigens into VV particles was not affected by loss of individual IEV or EEV-specific proteins or by redirection of B5R to the ER. These data suggest that (i) host cell antigens are excluded from the lipid envelope surrounding the IMV particle and (ii) membranes of the ER, IC and cis / medial -Golgi are not used to wrap IMV particles to form IEV. Lastly, the VV haemagglutinin was absent from one-third of IEV and CEV/EEV particles, whereas other EEV antigens were present in all these virions.
Simultaneous genetic chemoprotection of normal marrow cells and genetic chemosensitization of breast cancer cells in a mouse cancer gene therapy model. (1997)

Repeated exposures to high doses of chemotherapy are often required to eradicate solid tumors. The success of such high-dose therapy is often limited by the myelosuppressive and toxic effects of these drugs on bone marrow cells and by the intrinsic resistance of the cancer cells to chemotherapy. To test ways of using genetic modification of somatic cells to circumvent both of these problems, we first genetically modified normal bone marrow cells with multidrug resistance-1 (MDR-1) cDNA retroviral vectors to render these cells more resistant to p-glycoprotein-transported agents. Experiments conducted previously in a mouse model in our laboratory (E. G. Hanania et al., Cancer Gene Ther., 2: 251-261, 1995; E. G. Hanania and A. B. Deisseroth, Cancer Gene Ther., 1: 21-25, 1994), which involve transplantation of mouse marrow cells modified with the human MDR-1 cDNA, showed that the majority of the marrow cells of these animals were resistant to repetitive administration of myelotoxic doses of Taxol, a MDR-1-transported drug. Next, to test the effects of genetically modifying marrow cells to make them resistant to chemotherapy, and genetically modifying tumor cells to make them more sensitive to chemotherapy, a mouse breast cancer cell line was transfected with a plasmid expression vector that contained a wild-type p53 chemosensitization transcription unit. Others have shown that restoration of the p53 gene can lead to decreased proliferation, reduced tumorigenicity, and increased sensitivity to chemotherapy-induced apoptosis. In this animal model, the simultaneous use of both chemoprotection and chemosensitization vectors, which provided protection of the normal cells to the chemotherapy and at the same time sensitized the tumor cells to the toxic effects of the chemotherapy, resulted in levels of in vivo tumor reduction that were not possible when either genetic chemoprotection of marrow cells or chemosensitization of tumor cells was used alone. These data should be of interest to those who are studying ways of using genetic modification to improve the outcome of established chemotherapy treatment programs for solid tumors.
Synergistic antileukemic interactions between 17-AAG and UCN-01 involve interruption of RAF/MEK- and AKT-related pathways (2003)

Interactions between the protein kinase C (PKC) and Chk1 inhibitor UCN-01 and the heat shock protein 90 (Hsp90) antagonist 17-AAG have been examined in human leukemia cells in relation to effects on signal transduction pathways and apoptosis. Simultaneous exposure (30 hours) of U937 monocytic leukemia cells to minimally toxic concentrations of 17-AAG (eg, 400 nM) and UCN-01 (eg, 75 nM) triggered a pronounced increase in mitochondrial injury (ie, loss of mitochondrial membrane potential [Deltapsim]; cytosolic release of cytochrome c), caspase activation, and apoptosis. Synergistic induction of apoptosis was also observed in other human leukemia cell types (eg, Jurkat, NB4). Coexposure of human leukemia cells to 17-AAG and the PKC inhibitor bisindolylmaleimide (GFX) did not result in enhanced lethality, arguing against the possibility that the PKC inhibitory actions of UCN-01 are responsible for synergistic interactions. The enhanced cytotoxicity of this combination was associated with diminished Akt activation and marked down-regulation of Raf-1, MEK1/2, and mitogen-activated protein kinase (MAPK). Coadministration of 17-AAG and UCN-01 did not modify expression of Hsp90, Hsp27, phospho-JNK, or phospho-p38 MAPK, but was associated with further p34cdc2 dephosphorylation and diminished expression of Bcl-2, Mcl-1, and XIAP. In addition, inducible expression of both a constitutively active MEK1/2 or myristolated Akt construct, which overcame inhibition of ERK and Akt activation, respectively, significantly attenuated 17-AAG/UCN-01-mediated lethality. Together, these findings indicate that the Hsp90 antagonist 17-AAG potentiates UCN-01 cytotoxicity in a variety of human leukemia cell types and suggest that interference with both the Akt and Raf-1/MEK/MAP kinase cytoprotective signaling pathways contribute to this phenomenon.
Pembrolizumab plus Chemotherapy for Squamous Non–Small-Cell Lung Cancer (2018)

In patients with previously untreated metastatic, squamous NSCLC, the addition of pembrolizumab to chemotherapy with carboplatin plus paclitaxel or nab-paclitaxel resulted in significantly longer overall survival and progression-free survival than chemotherapy alone. (Funded by Merck Sharp & Dohme; KEYNOTE-407 ClinicalTrials.gov number, NCT02775435 .).
Collaborative Study of a Method for the Detection of Clostridium botulinum and Its Toxins in Foods (1977)

The mouse toxicity and protection technique for the detection and identification of Clostridium botulinum and its toxins in foods was collaboratively studied by 11 laboratories. Each laboratory received 4 samples of cream of mushroom soup; 2 contained spores and toxin of C. botulinum type A, 1 contained spores and toxin of C. botulinum type E, and 1 contained spores of C. sporogenes. The media used were cooked meat medium (beef heart or chopped liver broth) and trypticase peptone glucose yeast extract broth with trypsin. The results indicate that this method has a high degree of repeatability and reproducibility. All 11 laboratories correctly identified the toxins and the nontoxic sample in the food and detected and identified the viable spores in the samples by means of the subsequent cultures. This method has been adopted as official first action.

Normal T cell receptor-mediated signaling in T cell lines stably expressing HIV-1 envelope glycoproteins. (1993)

A series of T cell lines transfected to stably express HIV-1 envelope (env) glycoproteins were analyzed for viability and for T cell signaling. One transfectant was distinguished by its stable expression of gp120 and gp41, whereas the remainder of the T cell lines were similar to previously reported env-expressing T cells in synthesizing predominantly unprocessed env glycoprotein gp160. All of the transfectants were additionally constructed to express tat and rev proteins. None of these cell lines displayed growth abnormalities or spontaneous cell fusion, although the cell line synthesizing env gp120/gp41 could be induced to fuse and die when cocultured with a second cell expressing surface CD4. A cell line expressing only gp160 and the transfectant expressing gp160, gp120, and gp41 could be triggered normally via CD3-cross-linking as measured by protein tyrosine phosphorylation and by the induction of the CD69 activation marker. At levels of env protein expression sufficient to mediate syncytium formation and to kill cells, these HIV-1 env transfectants displayed no intrinsic T cell signaling abnormalities, suggesting that mechanisms other than a direct intracellular action of the tat or env proteins may be contributing to the deficit in Ag-specific T cell activation described subsequent to HIV infection in vivo and in vitro.
