Anchorage independent growth and plasminogen activator production by bovine endothelial cells. (1980)

Endothelial cells obtained from the aortae of 1- to 2-d-old calves were cloned at high efficiency using fibrin-coated dishes. Primary cultures as well as clones derived from them produced high fibrinolytic activity when grown on 125I-fibrin-coated dishes which was 90% dependent upon the presence of plasminogen. High plasminogen-dependent proteolytic activity was also demonstrated in endothelial cell lysates and in the culture medium of the cells. The production and secretion of the plasminogen activator(s) were found to increase during the log phase of cell growth and to reach a maximum level at confluence. These endothelial cells exhibited morphological phenotypes comparable to those of transformed cells when grown in the presence of acid-treated fetal calf, dog, or human serum. Furthermore, they demonstrated anchorage independent growth, and large colonies were formed in semisolid media. Spontaneous neoplastic transformation of these cells was excluded by karyotypic analysis, lack of tumorigenicity in athymic nude mice, and limited lifespan in culture. Cell clones isolated from colonies grown in agarose demonstrated the same growth characteristics and proteolytic activity as before plating in agarose. High fibrinolytic activity, morphological changes in the appropriate serum, and growth in semisolid media may therefore be indicative of the migratory and/or invasive capacity of both nontransformed endothelial cells as well as tumor cells.
Treatment of orthostatic hypotension: interaction of pressor drugs and tilt table conditioning. (1988)

We describe a patient with severe orthostatic hypotension in whom tilt table conditioning had a striking, beneficial effect. Upon presentation, the patient was unable even to sit, and the deconditioning associated with prolonged bed rest worsened his autonomic dysfunction. Although he was sensitive to the pressor effects of vasoconstrictor drugs (dihydroergotamine, caffeine, and a somatostatin analogue), these agents failed to stabilize his walking blood pressure. With drug therapy, however, the patient could maintain an adequate blood pressure while performing isometric exercises on a tilt table, whose angle was gradually increased during three weeks. After this conditioning program, pressor drug therapy made it possible for the patient to walk. Although the physiologic basis for this therapeutic response is unclear, our results indicate that tilt table conditioning may be an important adjunct to drug therapy in patients with severe orthostatic hypotension.
G Protein β1γ2 Subunits Promote Microtubule Assembly (1997)

alpha and betagamma subunits of G proteins are thought to transduce signals from cell surface receptors to intracellular effector molecules. Galpha and Gbetagamma have also been implicated in cell growth and differentiation, perhaps due to their association with cytoskeletal components. In this report Gbetagamma is shown to modulate the cytoskeleton by regulation of microtubule assembly. Specificity among betagamma species exists, as beta1gamma2 stimulates microtubule assembly, and beta1gamma1 is without any effect. Furthermore, a mutant beta1gamma2, beta1gamma2(C68S), which does not undergo prenylation and subsequent carboxyl-terminal processing on the gamma subunit, does not stimulate the formation of microtubules. beta immunoreactivity was detected exclusively in the microtubule fraction after assembly in the presence of beta1gamma2, suggesting a preferential association with microtubules rather than soluble tubulin. Crude microtubule fractions from ovine brain contain Gbetagamma, and electron microscopy reveals a specific association with microtubules. The decoration of microtubules by Gbetagamma appears to be strikingly similar to the periodic pattern observed for microtubule-associated proteins, suggesting a similar site of activation of microtubule assembly by both agents. It is suggested that reformation of the cytoskeleton represents an additional cellular process mediated by Gbetagamma.
Positive Cross-Regulatory Loop Ties GATA-3 to Estrogen Receptor α Expression in Breast Cancer (2007)

The transcription factor GATA-3 is required for normal mammary gland development, and its expression is highly correlated with estrogen receptor alpha (ER alpha) in human breast tumors. However, the functional role of GATA-3 in ER alpha-positive breast cancers is yet to be established. Here, we show that GATA-3 is required for estradiol stimulation of cell cycle progression in breast cancer cells. The role of GATA-3 in estradiol signaling requires the direct positive regulation of the expression of the ER alpha gene itself by GATA-3. GATA-3 binds to two cis-regulatory elements located within the ER alpha gene, and this is required for RNA polymerase II recruitment to ER alpha promoters. Reciprocally, ER alpha directly stimulates the transcription of the GATA-3 gene, indicating that these two factors are involved in a positive cross-regulatory loop. Moreover, GATA-3 and ER alpha regulate their own expression in breast cancer cells. Hence, this transcriptional coregulatory mechanism accounts for the robust coexpression of GATA-3 and ER alpha in human breast cancers. In addition, these results highlight the crucial role of GATA-3 for the response of ER alpha-positive breast cancers to estradiol. Moreover, they identify GATA-3 as a critical component of the master cell-type-specific transcriptional network including ER alpha and FoxA1 that dictates the phenotype of hormone-dependent breast cancer.
A framework for distributed simulation optimization (2001)

The system presented bridges the gap between three different research areas: discrete event simulation, heuristic optimization methods and distributed systems technology. Its goal is to provide a framework which supports an efficient implementation of simulation optimization projects, including heuristic optimum seeking procedures and parallel execution of experiments. It is written completely in Java and only uses components that are publicly available, including software libraries from academic institutions or the Java API from Sun Microsystems. The framework is well applicable for education and further research.
Treatment of acute limb ischemia by intramuscular injection of vascular endothelial growth factor gene. (1997)

These results suggest the feasibility of employing direct IM transfer of naked VEGF plasmid DNA to optimize treatment of acute limb ischemia.
Primary squamous cell carcinoma of the prostate. (2012)

Squamous cell carcinoma of the prostate is very rare, making less than 1% of all prostatic malignancies. We report a case of primary squamous cell carcinoma involving the prostate in an 80-year-old man with a history of benign prostatic hyperplasia, the patient underwent a transurethral resection prostate (TURP) procedure for progressive urinary obstruction. Biopsy proved the tumor to be squamous cell carcinoma.
Online Singing Voice Separation Using a Recurrent One-dimensional U-NET Trained with Deep Feature Losses (2019)

This paper proposes an online approach to the singing voice separation problem. Based on a combination of one-dimensional convolutional layers along the frequency axis and recurrent layers to enforce temporal coherency, state-of-the-art performance is achieved. The concept of using deep features in the loss function to guide training and improve the model's performance is also investigated.
Kinetics of the immune response of tumor‐bearing hamsters to two simian virus 40 coded non‐structural polypeptides present in simian virus 40 tumor cells (1982)

The kinetics of the immune response of hamsters transplanted with virus-free SV40 tumor cells (TSV5) to two SV40-coded non-structural proteins of 94,000 daltons (T antigen) and 17,000 daltons (t antigen) was studied in order to determine if the variation in the immune reactivity of serum from tumor-bearing animals towards these proteins can be explained on the basis of differential immune response during various stages of tumor growth. The results demonstrate that individual animals vary in their capacity to respond immunologically to T and t antigens in SV40-transformed cells and that, further, the immune response to T and t antigens is influenced by the stage of tumor development.
Flavonoids: A class of modulators with bifunctional interactions at vicinal ATP- and steroid-binding sites on mouse P-glycoprotein (1998)

A hexahistidine-tagged C-terminal nucleotide-binding domain (H 6 -NBD2) from mouse P-glycoprotein was designed, overexpressed, and purified as a highly soluble recombinant protein. Intrinsic fluorescence of its single tryptophan residue allowed monitoring of high-affinity binding of 2′(3′)- N -methylanthraniloyl-ATP (MANT-ATP), a fluorescent ATP derivative that induces a marked quenching correlated to fluorescence resonance-energy transfer. H 6 -NBD2 also bound all flavonoids known to modulate the multidrug resistance phenotype of P-glycoprotein-positive cancer cells, with similar affinities and relative efficiencies. Flavones (like quercetin or apigenin) bound more strongly than flavanones (naringenin), isoflavones (genistein), or glycosylated derivatives (rutin). Kaempferide, a 4′-methoxy 3,5,7-trihydroxy flavone, was even more reactive and induced a complete quenching of H 6 -NBD2 intrinsic fluorescence. Kaempferide binding was partly prevented by preincubation with ATP, or partly displaced upon ATP addition. Interestingly, kaempferide was also able to partly prevent the binding of the antiprogestin RU 486 to a hydrophobic region similar to that recently found, close to the ATP site, in the N-terminal cytosolic domain. Conversely, RU 486 partly prevented kaempferide binding, the effect being additive to the partial prevention by ATP. Furthermore, MANT-ATP binding, which occurred at the ATP site and extended to the vicinal steroid-interacting hydrophobic region, was completely prevented or displaced by kaempferide. All results indicate that flavonoids constitute a new class of modulators with bifunctional interactions at vicinal ATP-binding site and steroid-interacting region within a cytosolic domain of P-glycoprotein.
Temporal variability is a personalized feature of the human microbiome (2014)

Longitudinal sampling of a relatively large number of individuals allowed us to observe high levels of temporal variability in both diversity and community structure in all body habitats studied. These findings suggest that temporal dynamics may need to be considered when attempting to link changes in microbiome structure to changes in health status. Furthermore, our findings show that, not only is the composition of an individual's microbiome highly personalized, but their degree of temporal variability is also a personalized feature.
Molecular cloning of complementary DNA for a novel human hepatoma-derived growth factor. Its homology with high mobility group-1 protein. (1994)

A novel hepatoma-derived growth factor was purified from the conditioned medium of human hepatoma-derived cell line, HuH-7, by the assay of [3H]thymidine incorporation into Swiss 3T3 cells. Molecular cloning of a complementary DNA from the cDNA library of HuH-7 cells was done on the basis of the N-terminal amino acid sequence. This protein was acid- and heat-labile heparin-binding protein and inactivated by reducing condition. The cDNA is 2.4 kilobase pairs long, and the deduced amino acid sequence from cDNA contained 240 amino acids without a signal peptide-like N-terminal hydrophobic sequence. Heparin column-eluted fraction of the conditioned medium of Cos-7 cells transfected by the cDNA stimulated the DNA synthesis. Northern blot analysis revealed its ubiquitous expression in several tumor-derived cell lines, as well as in normal tissues. The primary sequence shares homology with the high mobility group (HMG)-1 protein (23.4% amino acid identity and 35.6% similarity). However, its hydrophobic profile was distinct from that of HMG-1 except for the C-terminal acidic region, and it contained no apparent HMG box motif. Immunofluorescence study showed that it is localized in the cytoplasma of hepatoma cells. These findings suggest that this factor is a novel heparin-binding protein, with mitogenic activity for fibroblasts.
Phosphorylation of synthetic peptides containing Tyr-Met-X-Met motifs by nonreceptor tyrosine kinases in vitro. (1993)

Several tyrosine phosphorylation sites in the insulin receptor kinase substrate IRS-1 are predicted to be within Tyr-Met-X-Met (YMXM) motifs, and synthetic peptides corresponding to these sequences are excellent substrates for the insulin receptor kinase in vitro (Shoelson, S. E., Chatterjee, S., Chaudhuri, M., and White, M. F. (1992) Proc. Natl. Acad. Sci. U. S. A. 89, 2027-2031). In this study, YMXM-containing peptides are shown to act as substrates for two members of the nonreceptor subfamily of tyrosine kinases, v-Src and v-Abl (the transforming gene products of Rous sarcoma virus and Abelson murine leukemia virus, respectively). For v-Src, a baculovirus expression system was used which was capable of producing milligram quantities of pure 60-kDa v-Src in Spodoptera frugiperda (Sf9) cells. The source of v-Abl was an Escherichia coli expression vector that produces a fusion protein of glutathione S-transferase with the abl catalytic domain. The synthetic YMXM-containing peptides had among the highest apparent affinities described to date for either tyrosine kinase, with Km values as low as 97 microM for v-Src and v-Abl. Comparisons with the results obtained with the insulin receptor kinase revealed differences in substrate specificity among the enzymes. In particular, v-Src was more tolerant of substitutions at the Met+1 and Met+3 positions in the YMXM motif than either v-Abl or the insulin receptor kinase but was more dependent on the presence of a preceding acidic amino acid. For v-Abl, the presence of threonine at any position in the YMXM motif caused a reduction in catalytic efficiency. Phosphorylated YMXM motifs are recognition elements for binding to the src homology 2 domains of phosphatidylinositol 3'-kinase and additional proteins; hence, differences in specificity of tyrosine kinases toward YMXM-containing proteins may have relevance to downstream signaling events.
Vaginal Microbiome: Rethinking Health and Disease (2012)

Vaginal microbiota form a mutually beneficial relationship with their host and have a major impact on health and disease. In recent years our understanding of vaginal bacterial community composition and structure has significantly broadened as a result of investigators using cultivation-independent methods based on the analysis of 16S ribosomal RNA (rRNA) gene sequences. In asymptomatic, otherwise healthy women, several kinds of vaginal microbiota exist, the majority often dominated by species of Lactobacillus, while others are composed of a diverse array of anaerobic microorganisms. Bacterial vaginosis is the most common vaginal condition and is vaguely characterized as the disruption of the equilibrium of the normal vaginal microbiota. A better understanding of normal and healthy vaginal ecosystems that is based on their true function and not simply on their composition would help better define health and further improve disease diagnostics as well as the development of more personalized regimens to promote health and treat diseases.

possible. This capability provides an advantage to the eavesdropper and a serious disadvantage to the target of the eavesdropping.
Generation of Broadband VUV Light Using Third-Order Cascaded Processes (2001)

We report the first demonstration of broadband VUV light generation through cascaded nonlinear wave mixing in a gas. Using a hollow-fiber geometry to achieve broad-bandwidth phase-matching, frequency conversion of ultrashort-pulse Ti:sapphire laser pulses from the visible into the deep UV around 200 and 160 nm is achieved. A new type of quasi-phase-matching is also observed in the VUV for the first time. Conversion using cascaded processes exhibits higher efficiencies, shorter pulse durations, and broader bandwidths than other schemes for generating light in the deep UV, and will enable many applications in science and technology.
Iron and fibroblast growth factor 23 in X-linked hypophosphatemia (2014)

Background
Excess fibroblast growth factor 23 (FGF23) causes hypophosphatemia in autosomal dominant hypophosphatemic rickets (ADHR) and X-linked hypophosphatemia (XLH). Iron status influences C-terminal FGF23 (incorporating fragments plus intact FGF23) in ADHR and healthy subjects, and intact FGF23 in ADHR. We hypothesized that in XLH serum iron would inversely correlate to C-terminal FGF23, but not to intact FGF23, mirroring the relationships in normal controls.
Fibronectin Matrix Regulates Activation of RHO and CDC42 GTPases and Cell Cycle Progression (1998)

Adherent cells assemble fibronectin into a fibrillar matrix on their apical surface. The fibril formation is initiated by fibronectin binding to the integrins alpha5 beta1 and alphav beta3, and is completed by a process that includes fibronectin self-assembly. We found that a 76- amino acid fragment of fibronectin (III1-C) that forms one of the self-assembly sites caused disassembly of preformed fibronectin matrix without affecting cell adhesion. Treating attached fibroblasts or endothelial cells with III1-C inhibited cell migration and proliferation. Rho-dependent stress fiber formation and Rho-dependent focal contact protein phosphorylation were also inhibited, whereas Cdc42 was activated, leading to actin polymerization into filopodia. ACK (activated Cdc42-binding kinase) and p38 MAPK (mitogen-activated protein kinase), two downstream effectors of Cdc42, were activated, whereas PAK (p21-activated kinase) and JNK/SAPK (c-Jun NH2-terminal kinase/ stress-activated protein kinase) were inhibited. III1-C treatment also modulated activation of JNK and ERK (extracellular signal-regulated kinases) in response to growth factors, and reduced the activity of the cyclin E-cdk2 complex. These results indicate that the absence of fibronectin matrix causes activation of Cdc42, and that fibronectin matrix is required for Rho activation and cell cycle progression.
Thoracoscopic Splanchnicectomy for Pain Relief in Unresectable Pancreatic Cancer (2000)

Thoracoscopic splanchnicectomy offered substantial short-term relief of pain in patients with unresectable pancreatic cancer, and significantly ameliorated the quality of their residual life.
Susceptibility of multiresistant serotype 012 Pseudomonas aeruginosa to fosfomycin in combination with other antibiotics. (1994)

Serotype 012 represented 15% of 244 isolates of Pseudomonas aeruginosa isolated in the hospital over a 2 year-period and most isolates of this serotype were resistant to multiple antibiotics. Combination experiments showed that fosfomycin and amikacin together were active against 92% of 012 isolates. It is recommended that serotyping be used systematically to identify 012 strains rapidly and fosfomycin/amikacin be considered as a presumptive antipseudomonal therapy in 012 infections.
MINIREVIEW: Cyclic AMP Response Element Binding Proteins: A Cornucopia of Transcription Factors (1990)

The expression of many cellular genes in higher eukaryotes is controlled by hormones. At the level of transcription the regulation of genes is mediated through the interactions of DNA-binding proteins with specific DNA promoter elements which are generally located in the 5′-flanking regions of the genes upstream from the transcription start sites (1–3). In the circumstances of the steroid and thyroid hormones, substances that readily pass through the plasma membrane and enter cells, the DNA-binding proteins are the hormone receptors themselves (4). Binding of ligand to the receptor either evokes translocation of the receptor to the nucleus where it binds to the DNA control element and activates transcription (steroid hormone receptors) and/or activates prebound receptors (T3, retinoic acid receptors).
Fluorescence-guided resection of glioblastoma multiforme by using high-dose fluorescein sodium (2003)

The authors have recently performed a fluorescence-guided tumor resection procedure by using high-dose fluorescein sodium without any special surgical microscopes for the intraoperative visualization of glioblastoma multiforme (GBM), and they report on the actual procedure and clinicopathological findings. Thirty-two patients with GBMs underwent tumor resection during which this fluorescence-guided procedure was used. Fluorescein sodium (20 mg/kg) was intravenously injected after dural opening at the craniotomy site. The tumor was stained almost homogeneously yellow and the color was intense enough to be readily perceived for resection. The center of the solid lesion was stained a deep yellow and surrounded by a transition zone that was faintly stained. The colored lesion was clearly distinguishable from the unstained zone outside the GBM, particularly in the white matter. Both the deeply and faintly stained regions included endothelial proliferation and dense tumor cells. In the unstained region, less dense tumor cells were consistently revealed; however, no endothelial proliferation could be seen. Gross-total resection (GTR) was successful in 84.4% of the patients who received an injection of fluorescein sodium, which accounted for 100% of those in whom all the visible yellow color (both the deeply and faintly stained regions) was judged to have been resected during operation. Gross-total resection was performed in 100% of the patients who underwent the fluorescence-guided procedure and assigned to Stage I, a GBM stage in which, as a therapeutic policy, the tumor should be resected as radically as possible. The GTR rates in patients who received fluorescein sodium were significantly higher than those in patients who did not (73 patients with GBMs who underwent tumor resection without the fluorescence-guided procedure). Although the extent of surgery was revealed to be one of the significant and independent prognostic factors for GBM, the fluorescein sodium-guided resection procedure was not a significant or independent prognostic factor in this series. This surgical procedure does not require any special surgical microscopic equipment and is simple, safe, useful, readily accomplished, and universally available for resection of GBMs. Its efficacy simplifies the surgical procedure of navigating the stained lesion from the unstained area to achieve GTR of GBMs, which can be demonstrated on magnetic resonance images.
Human Demodex Mite: The Versatile Mite of Dermatological Importance (2013)

Demodex mite is an obligate human ecto-parasite found in or near the pilo-sebaceous units. Demodex folliculorum and Demodex brevis are two species typically found on humans. Demodex infestation usually remains asymptomatic and may have a pathogenic role only when present in high densities and also because of immune imbalance. All cutaneous diseases caused by Demodex mites are clubbed under the term demodicosis or demodicidosis, which can be an etiological factor of or resemble a variety of dermatoses. Therefore, a high index of clinical suspicion about the etiological role of Demodex in various dermatoses can help in early diagnosis and appropriate, timely, and cost effective management.
Simulation of atmospheric transport and droplet–thin film collisions in desorption electrospray ionization (2007)

Computational fluid dynamics is used to model atmospheric transport and droplet-thin film (surface) collisions in desorption electrospray ionization; experimentally obtained droplet properties are replicated in the simulations while a "droplet pick-up" mechanism of analyte transport is confirmed.
