Monitoring body positions and movements during sleep using WISPs (2010)

Sleep monitoring is very important for elderly people as inadequate and irregular sleep are often related to serious diseases such as depression and diabetes. In many cases, it is necessary to monitor the body positions and movements made while sleeping because of their relationships to particular diseases (i.e., sleep apnea and restless legs syndrome). Analyzing movements during sleep also helps in determining sleep quality and irregular sleeping patterns. This paper presents a sleep monitoring system based on the WISP platform - active RFID-based sensors equipped with accelerometers. We show how our system accurately infers fine-grained body positions from accelerometer data collected from the WISPs attached to the bed mattress. Movements and their duration are also detected by the system. We present the results of our empirical study from 10 subjects on three different mattresses in controlled experiments to show the accuracy of our inference algorithms. Finally, we evaluate the accuracy of the movement detection and body position inference for six nights on one subject, and compare these results with two baseline systems: one that uses bed pressure sensors and the other is an iPhone application.

Potential increased tumor-dose delivery with combined 131I-MIBG and 90Y-DOTATOC treatment in neuroendocrine tumors: a theoretic model. (2006)

Combining (131)I-MIBG and (90)Y-DOTATOC for radiotherapy of neuroendocrine tumors can significantly increase the delivered tumor dose over the dose obtained from using either agent alone. Prior knowledge of the normal-organ and tumor dosimetry of both agents is required to determine the magnitude of the increase.
Secretion ofAspergillus oryzaeAlkaline Protease in an Osmophilic Yeast,Zygosaccharomyces rouxii (1990)

To produce Aspergillus oryzae alkaline protease (Alp) in an osmophilic yeast Zygosaccharomyces rouxii, we constructed an expression plasmid consisting of the Z. rouxii glyceraldehyde-3-phosphate dehydrogenase (GAPDH) promoter, the prepro-Alp cDNA of A. oryzae, the whole sequence of Z. rouxii plasmid pSR1, and the G418 resistant gene. The resulting plasmid, when introduced into Z. rouxii cells, directed the secretion of a large amount (about 300 mg/l) of Alp into the culture medium. The N-terminus and specific activity of the enzyme were identical to those of A. oryzae Alp.
A viral suppressor of RNA silencing differentially regulates the accumulation of short interfering RNAs and micro-RNAs in tobacco (2002)

Two major classes of small noncoding RNAs have emerged as important regulators of gene expression in eukaryotes, the short interfering RNAs (siRNAs) associated with RNA silencing and endogenous micro-RNAs (miRNAs) implicated in regulation of gene expression. Helper component-proteinase (HC-Pro) is a viral protein that blocks RNA silencing in plants. Here we examine the effect of HC-Pro on the accumulation of siRNAs and endogenous miRNAs. siRNAs were analyzed in transgenic tobacco plants silenced in response to three different classes of transgenes: sense-transgenes, inverted-repeat transgenes, and amplicon-transgenes. HC-Pro suppressed silencing in each line, blocking accumulation of the associated siRNAs and allowing accumulation of transcripts from the previously silenced loci. HC-Pro-suppression of silencing in the inverted-repeat- and amplicon-transgenic lines was accompanied by the apparent accumulation of long double-stranded RNAs and proportional amounts of small RNAs that are larger than the siRNAs that accumulate during silencing. Analysis of these results suggests that HC-Pro interferes with silencing either by inhibiting siRNA processing from double-stranded RNA precursors or by destabilizing siRNAs. In contrast to siRNAs, the accumulation of endogenous miRNAs was greatly enhanced in all of the HC-Pro-expressing lines. Thus, our results demonstrate that accumulation of siRNAs and miRNAs in plants can be differentially regulated by a viral protein. The fact that HC-Pro affects the miRNA pathway raises the possibility that this pathway is targeted by plant viruses as a means to control gene expression in the host.
Dual-Feed Dual-Polarized Patch Antenna With Low Cross Polarization and High Isolation (2009)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> In this communication, a dual-feed dual-polarized microstrip antenna with low cross polarization and high isolation is experimentally studied. Two different feed mechanisms are designed to excite a dual orthogonal linearly polarized mode from a single radiating patch. One of the two modes is excited by an aperture-coupled feed, which comprises a compact resonant annular-ring slot and a T-shaped microstrip feedline; while the other is excited by a pair of meandering strips with a 180<formula formulatype="inline"><tex Notation="TeX">$^{\circ}$</tex> </formula> phase differences. Both linearly polarized modes are designed to operate at 2400-MHz frequency band, and from the measured results, it is found that the isolation between the two feeding ports is less than 40 dB across a 10-dB input-impedance bandwidth of 14%. In addition, low cross polarization is observed from the radiation patterns of the two modes, especially at the broadside direction. Simulation analyses are also carried out to support the measured results. </para>
Gemcitabine alone or with cisplatin for the treatment of patients with locally advanced and/or metastatic pancreatic carcinoma (2002)

BACKGROUND A prospective, randomized Phase III trial was performed to determine whether, compared with gemcitabine (GEM) alone, the addition of cisplatin (CDDP) to GEM was able to improve the time to disease progression and the clinical benefit rate in patients with advanced pancreatic adenocarcinoma. The objective response rate, overall survival rate, and toxicity patterns of patients in the two treatment arms were evaluated as secondary end points. METHODS Patients with measurable, locally advanced and/or metastatic pancreatic adenocarcinoma were randomized to receive GEM (Arm A) or a combination of GEM and CDDP (Arm B). In Arm A, a dose of 1000 mg/m2 GEM per week was administered for 7 consecutive weeks, and, after a 2-week rest, treatment was resumed on Days 1, 8, and 15 of a 28-day cycle for 2 cycles. In Arm B, CDDP was given at a dose of 25 mg/m2 per week 1 hour before GEM at the same dose that was used in Arm A. On Day 22, only GEM was administered. Patients were restaged after the first 7 weeks of therapy and then again after the other 2 cycles. RESULTS A total of 107 patients entered the trial: Fifty-four patients were randomized to Arm A, and 53 patients were randomized to Arm B. The median time to disease progression was 8 weeks in Arm A and 20 weeks in Arm B; this difference was statistically significant (P = 0.048). In Arm A, one complete response and four partial responses were recorded on the basis of an intent-to-treat analysis, with an overall response rate of 9.2% (95% confidence interval [95%CI], 3–20%). In Arm B, there were no complete responses, whereas 14 partial responses were achieved, with an overall response rate of 26.4% (95%CI, 15–40%). This difference in the overall response rates was statistically significant (P = 0.02). The tumor growth control rate (i.e., total number of patients who achieved complete responses, partial responses, and stable disease) was 42.6% (95%CI, 29–57%) in Arm A and 56.6% (95%CI, 42–70%) in Arm B. A clinical benefit was observed in 21 of 43 patients (49%) in Arm A and in 20 of 38 patients (52.6%) in Arm B without any significant difference. The median overall survival was 20 weeks for patients in Arm A and 30 weeks for patients in Arm B (P = 0.43). Toxicity was mild in both treatment arms, with no significant differences between the two groups except for the statistically higher incidence of Grade 1–2 asthenia in Arm B (P = 0.046). CONCLUSIONS The addition of CDDP to GEM significantly improved the median time to disease progression and the overall response rate compared with GEM alone. The clinical benefit rate was similar in both arms, whereas the median overall survival rate was more favorable for Arm B, although the difference did not attain statistical significance. The authors conclude that the combination of CDDP and GEM currently may be considered as an optimal treatment for patients with locally advanced and/or metastatic adenocarcinoma of the pancreas.

Adaptation of the translation model for statistical machine translation based on information retrieval (2005)

In this paper we present experiments concerning translation model adaptation for statistical machine translation. We develop a method to adapt translation models using in- formation retrieval. The approach selects sentences similar to the test set to form an adapted training corpus. The method allows a better use of additionally available out-of-domain training data or finds in-domain data in a mixed corpus. The adapted translation models significantly improve the translation performance compared to competitive baseline sys- tems.
Cutting Edge: Inhibition of TLR and FcR Responses in Macrophages by Triggering Receptor Expressed on Myeloid Cells (TREM)-2 and DAP12 (2006)

DAP12 is an ITAM-containing adapter that associates with receptors in myeloid and NK cells. DAP12-associated receptors can give activation signals leading to cytokine production; however, in some situations, DAP12 inhibits cytokine production stimulated through TLRs and FcRs. Here we show that Triggering Receptor Expressed on Myeloid cells (TREM)-2 is responsible for the DAP12-mediated inhibition in mouse macrophages. A chimeric receptor composed of the extracellular domain of TREM-2 and the cytoplasmic domain of DAP12 inhibited the TLR- and FcR-induced TNF production of DAP12-deficient macrophages, whereas a TREM-1 chimera did not. In wild-type macrophages, TREM-2 knockdown increased TLR-induced TNF production. A TREM-2 Fc fusion protein bound to macrophages, indicating that macrophages express a TREM-2 ligand. Thus, the interaction of TREM-2 and its ligand results in an inhibitory signal that can reduce the inflammatory response.
Gene expression profiling identifies Fibronectin 1 and CXCL9 as candidate biomarkers for breast cancer screening (2010)

This study suggests that Fibronectin 1/CXCL9 dosage in serum could screen a significant rate of BC, including ER-negative, and that differential gene expression analysis is a good approach to select candidate biomarkers to set up blood assays cancer screening.
CXC Chemokine Receptor 3 and CC Chemokine Receptor 4 Expression in T-Cell and NK-Cell Lymphomas with Special Reference to Clinicopathological Significance for Peripheral T-Cell Lymphoma, Unspecified (2004)

We recently reported expression of the chemokine receptors CXC chemokine receptor 3 (CXCR3) and CC chemokine receptor 4 (CCR4) in adult T-cell leukemia/lymphoma and showed a preferential expression of CCR4 and its association with an unfavorable outcome. In the present study, we extend our adult T-cell leukemia/lymphoma study to other subtypes of T- and NK-cell lymphoma, to clarify whether a characteristic chemokine receptor expression pattern is obtained for each of the subtypes defined by the WHO classification. CXCR3 and CCR4 were rarely expressed in three well-defined subtypes, precursor T-lymphoblastic lymphoma, anaplastic lymphoma kinase-positive anaplastic large cell lymphoma, and extranodal NK/T-cell lymphoma. A CXCR3-dominant expression pattern was observed in angioimmunoblastic T-cell lymphoma, while a CCR4-dominant expression pattern was observed in mycosis fungoides in transformation and in anaplastic lymphoma kinase-negative anaplastic large cell lymphoma. CXCR3 and CCR4 were heterogeneously expressed in peripheral T-cell lymphomas, unspecified (PTCLU). We next focused on PTCLU and analyzed the clinical significance of the chemokine receptors and their association with FoxP3, a hallmark of immunoregulatory T (Treg) cells. Multivariate analysis showed that CCR4 expression was an independent and significant unfavorable prognostic factor (P < 0.001). A significant correlation was found between mRNA expression of CCR4 and FoxP3, suggesting a possible association of CCR4-positive tumors with Treg cells and thereby with an immunocompromised state. Chemokine receptors may be useful not only for further characterization of the T- and NK-cell lymphomas but also in predicting clinical outcomes for patients. We suggest that a specific therapy targeting the CCR4 molecule may be developed as an alternative treatment for patients with CCR4-positive tumors.
Association between insulin resistance and plasma amino acid profile in non‐diabetic Japanese subjects (2014)

The present study shows that the insulin resistance-related change in amino acid profile is also observed in non-diabetic Japanese subjects. These amino acids include BCAAs (valine, isoleucine and leucine) and aromatic amino acids (tyrosine and phenylalanine), in agreement with previous studies carried out using different ethnic groups with different degrees of obesity and insulin resistance.
Methods of amorphization and investigation of the amorphous state (2013)

The amorphous form of pharmaceutical materials represents the most energetic solid state of a material. It provides advantages in terms of dissolution rate and bioavailability. This review presents the methods of solid- -state amorphization described in literature (supercooling of liquids, milling, lyophilization, spray drying, dehydration of crystalline hydrates), with the emphasis on milling. Furthermore, we describe how amorphous state of pharmaceuticals differ depending on the method of preparation and how these differences can be screened by a variety of spectroscopic (X-ray powder diffraction, solid state nuclear magnetic resonance, atomic pairwise distribution, infrared spectroscopy, terahertz spectroscopy) and calorimetry methods.
A Radical Approach to Anionic Chemistry: Synthesis of Ketones, Alcohols, and Amines (2019)

Historically accessed through two-electron, anionic chemistry, ketones, alcohols, and amines are of foundational importance to the practice of organic synthesis. After placing this work in proper historical context, this Article reports the development, full scope, and a mechanistic picture for a strikingly different way of forging such functional groups. Thus, carboxylic acids, once converted to redox-active esters (RAEs), can be utilized as formally nucleophilic coupling partners with other carboxylic derivatives (to produce ketones), imines (to produce benzylic amines), or aldehydes (to produce alcohols). The reactions are uniformly mild, operationally simple, and, in the case of ketone synthesis, broad in scope (including several applications to the simplification of synthetic problems and to parallel synthesis). Finally, an extensive mechanistic study of the ketone synthesis is performed to trace the elementary steps of the catalytic cycle and provide the end-user with a clear and understandable rationale for the selectivity, role of additives, and underlying driving forces involved.
Conformationally Specific Enhancement of Receptor-Mediated LDL Binding and Internalization by Peptide Models of a Conserved Anionic N-Terminal Domain of Human Apolipoprotein E (1996)

In this paper, we test the hypothesis that peptide models of a highly conserved domain of apolipoprotein E (amino acids 41-60 in human apo E) modulate the binding and internalization of LDL to cell surface receptors in a conformationally specific manner. Three peptides were compared: peptide I containing the natural sequence of amino acids 41-60 of human apo E; peptide III containing side-chain lactam cross-links designed to enhance alpha-helical structure; and peptide II containing cross-links designed to prevent formation of alpha-helices. Peptide III was shown previously to consist of two short alpha-helical domains linked by a turn and to have more alpha-helical content than peptide I, while peptide II was shown to have less helical content than either peptide III or I(Luo et al., 1994). Peptide III induced a 30-fold increase in the specific binding of 125I-LDL to normal human skin fibroblasts and a 60-fold increase in the binding to fibroblasts lacking the LDL-R. This same peptide also restored the binding to normal fibroblasts of 125I-LDL from a patient with familial defective apolipoprotein B, the R3500-->Q mutation. Analysis of binding indicated an increase in the apparent number of binding sites, with little effect on the affinity of 125I-LDL for the cell surface. Heparinase treatment of the cells did not abrogate this effect, suggesting that the increased binding is not mediated by cell surface glycans. LDL internalization but not degradation was also increased by peptide III. Similar but smaller effects were also induced by peptide I. Peptide II was much less active than peptide I or III. Thus, the order of biological activity was the same as the order of alpha-helical content, i.e., peptide III > peptide I > peptide II. These results suggest a hitherto unknown biological function for a highly conserved domain of apolipoprotein E, and this bioactivity was shown by peptide models to be specific to the alpha-helical conformation.
Selective titanium disilicide by low-pressure chemical vapor deposition (1989)

TiSi2 was deposited onto both Si and SiO2 substrates by low-pressure chemical vapor deposition. By using both TiCl4 and SiH4 as source gases, the reaction could be controlled to yield either selective TiSi2 on Si substrates only, or blanket silicide films. Experimental conditions providing for selective deposition were investigated. Mass spectroscopy data and thermodynamic calculations were in good agreement with each other and provided rational explanations of observed phenomena. Reaction of TiCl4 vapor with Si yields TiSi2, but is accompanied by excessive Si consumption. This etching reaction may be moderated by increasing the reactor pressure while keeping the substrate temperature around 900 K, and by the introduction of H2 and/or SiH4 into the reactant gas mixture.

A Prediction Rule to Identify Low-Risk Patients with Community-Acquired Pneumonia (1997)

The prediction rule we describe accurately identifies the patients with community-acquired pneumonia who are at low risk for death and other adverse outcomes. This prediction rule may help physicians make more rational decisions about hospitalization for patients with pneumonia.
Generation of Th1-Polarizing Dendritic Cells Using the TLR7/8 Agonist CL075 (2010)

In this paper, we describe a new method for preparation of human dendritic cells (DCs) that secrete bioactive IL-12(p70) using synthetic immunostimulatory compounds as TLR7/8 agonists. Monocyte-derived DCs were generated using a procedure that provided mature cells within 3 d. Several maturation mixtures that contained various cytokines, IFN-gamma, different TLR agonists, and PGE(2) were compared for impact on cell recovery, phenotype, cytokine secretion, migration, and lymphocyte activation. Mixtures that included the TLR7/8 agonists R848 or CL075, combined with the TLR3 agonist polyinosinic:polycytidylic acid, yielded 3-d mature DCs that secreted high levels of IL-12(p70), showed strong chemotaxis to CCR7 ligands, and had a positive costimulatory potential. They also had excellent capacity to activate NK cells, effectively polarized CD4(+) and CD8(+) T cells to secrete IFN-gamma and to induce T cell-mediated cytotoxic function. Thereby, mature DCs prepared within 3 d using such maturation mixtures displayed optimal functions required for vaccine development.
Oncolytic vaccinia virus GLV-1h68 strain shows enhanced replication in human breast cancer stem-like cells in comparison to breast cancer cells (2012)

Taken together, our findings indicate that GLV-1h68 efficiently replicates and kills cancer stem-like cells. Thus, GLV-1h68 may become a promising agent for eradicating both primary and metastatic tumors, especially tumors harboring cancer stem-like cells that are resistant to chemo and/or radiotherapy and may be responsible for recurrence of tumors.
Association of extended in vitro proliferative potential with loss of p16INK4 expression. (1996)

This study addresses the question of whether loss of p16INK4 expression contributes to the immortalization of human cells. In vitro immortalization usually proceeds through two phases. In the first phase (lifespan extension), cells continue proliferating and their telomeres continue shortening beyond the point at which normal cells become senescent. In the second phase (immortalization), the cells activate a telomere maintenance mechanism and acquire an unlimited proliferative potential. It has previously been shown that immortalized cells containing viral oncoproteins that bind and inactivate p110RB contain wild-type p16INK4; we therefore examined the p16INK4 status of cell lines that became immortalized in vitro in the absence of these oncoproteins. Three such lines were identified: III-CF/.2A1 and III-CF/E6A2 (both derived from Li-Fraumeni syndrome fibroblasts, probably by spontaneous immortalization) and MePV-231 (normal mesothelial cells transfected with HPV-16 E6/E7 genes that underwent deletion of these genes before immortalization). In each case p16INK4 expression was lost at or before immortalization. Further, a cell strain was identified that had an extended but finite lifespan associated with loss of p16INK4 (and p53) expression. Thus loss of p16INK4 expression was associated with extended in vitro lifespan but was not sufficient for immortalization, even in the absence of wild-type p53.
