Functional Properties of Two Naturally Occurring Isoforms of the Human Insulin Receptor in Chinese Hamster Ovary Cells* (1991)

We and others have previously demonstrated that the human insulin receptor messenger RNA (mRNA) is alternatively spliced such that the 36-nucleotide sequence encoded by exon 11 of the receptor gene is included (Ex11+) or excluded (Ex11-). Although both Ex11- and Ex11+ insulin receptors which differ in the presence or absence of 12 amino acids in the carboxy-terminal alpha-subunit have been demonstrated to function as insulin receptors when independently overexpressed and studied, the possibility that subtle functional differences between the two isoforms exist has received limited attention. Given that the relative abundance of the two mRNA transcripts is highly regulated in a tissue-specific manner, differences in the functional properties of the two receptor variants might contribute to tissue-specific differences in insulin receptor function and insulin action that are known to exist. To address this hypothesis, we transfected cDNAs encoding the two receptor isoforms into Chinese hamster ovary (CHO) cells and prepared several stable CHO cell lines expressing high numbers of Ex11- or Ex11+ receptors. Several functional properties of the expressed insulin receptors were compared in parallel with the following results: 1) steady state binding of insulin to cells expressing the Ex11- isoform exhibited higher (approximately 2-fold) affinity; 2) using two different methods, a significant difference in receptor-mediated insulin internalization was noted such that the Ex11- isoform displayed a higher (approximately 25% increase in the rate constant, Ke) rate of internalization; 3) partially purified Ex11- and Ex11+ receptors displayed similar maximal and insulin dose-response characteristics for receptor autophosphorylation and kinase activity toward an exogenous substrate (poly Glu-Tyr, 4:1); 4) the ability of expressed Ex11- and Ex11+ receptors to couple to a metabolic (glucose incorporation into glycogen) and mitogenic (thymidine incorporation into DNA) action of insulin was not discernibly different. Thus, when expressed in CHO cells, the two alternatively spliced isoforms of the insulin receptor have subtle differences in insulin binding affinity and the kinetics of ligand-stimulated internalization that would be expected to influence the pattern of insulin receptor expression and signaling in vivo in a tissue-specific manner.

A 5 volt only 16M bit flash EEPROM cell with a simple stacked gate structure (2002)

A 3.6 mu m/sup 2/ 5 V only 16 Mb flash EEPROM cell was obtained using a simple stacked gate structure and a conventional 0.6 mu m CMOS process. A single 5 V power supply operation of the simple stacked gate cell was realized by optimizing the well impurity concentration and the drain structure and using a gate negative biased erasing operation. It is also shown that the gate negative biased erasing operation mode is very effective in improving the cell endurance characteristics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The versatile use of exhaled volatile organic compounds in human health and disease (2012)

Exhaled breath contains thousands of volatile organic compounds (VOCs) of which the composition varies depending on health status. Various metabolic processes within the body produce volatile products that are released into the blood and will be passed on to the airway once the blood reaches the lungs. Moreover, the occurrence of chronic inflammation and/or oxidative stress can result in the excretion of volatile compounds that generate unique VOC patterns. Consequently, measuring the total amount of VOCs in exhaled air, a kind of metabolomics also referred to as breathomics, for clinical diagnosis and monitoring purposes gained increased interest over the last years. This paper describes the currently available methodologies regarding sampling, sample analysis and data processing as well as their advantages and potential drawbacks. Additionally, different application possibilities of VOC profiling are discussed. Until now, breathomics has merely been applied for diagnostic purposes. Exhaled air analysis can, however, also be applied as an analytical or monitoring tool. Within the analytic perspective, the use of VOCs as biomarkers of oxidative stress, inflammation or carcinogenesis is described. As monitoring tool, breathomics can be applied to elucidate the heterogeneity observed in chronic diseases, to study the pathogen(s) responsible for occurring infections and to monitor treatment efficacy.
Brainwave entrainment for better sleep and post‐sleep state of young elite soccer players – A pilot study (2013)

The effect of sleep deprivation on psychophysical performance and well-being is comprehensively investigated. Research investigating the effect of improved sleep is rare. Just as little exists about attempts to support athletic mental state and performance by improving sleep quality. This study aims to investigate whether sleep quality of top athletes can be improved by auditory brainwave entrainment and whether this leads to enhancements of post-sleep psychophysical states. In a pilot study, 15 young elite soccer players were stimulated for eight weeks during sleep with binaural beats around 2-8 Hz. Once a week after wake-up, participants completed three different questionnaires: a sleep diary, an adjective list for psychophysical and motivational state, and a self-assessment questionnaire for sleep and awakening quality. Fifteen sport students executed the same protocol sleeping on the same pillow, but without stimulation. Subjective ratings of sleep and awakening quality, sleepiness and motivational state were significantly improved only in the intervention group, but did not impact their perceived physical state. In summary, eight weeks of auditory stimulation with binaural beats improved perceived sleep quality and the post-sleep state of athletes, whereas the effect on physical level is assumed to occur in a time-delayed fashion. It seems to be worthwhile - to further elaborate long-time effects and consequences on physical and mental performance.
Spiramycin uptake by alveolar macrophages (1988)

The in-vitro and in-vivo uptake of spiramycin by human and animal alveolar macrophages was studied. In-vitro penetration was studied in guinea pig and human alveolar macrophages incubated in medium 199 at 37 degrees C containing spiramycin at various concentrations. Results were expressed as the cellular/extracellular concentration ratio (C/E). The in-vivo study was performed in patients receiving 500 or 1000 mg spiramycin every 8 h as a 1-h infusion on day 1. A single infusion was given on day 2, 2 h before serum and bronchoalveolar lavage (BAL) sampling. Spiramycin was assayed by HPLC, and by a microbiological assay. In guinea pig alveolar macrophages, the C/E ratio of spiramycin after 60 min at 37 degrees C was 20.3 +/- 6.5 when the concentration was 10 mg/l. In human alveolar macrophages, the C/E ratio was 21.3 +/- 8.7 at 5 mg/l spiramycin and 23.8 +/- 8.7 at 50 mg/l. The accumulated spiramycin was slowly released when the cells (guinea pig alveolar macrophages) were washed and re-incubated in antibiotic free medium. Spiramycin was able to penetrate the alveolar space. In BAL supernatant, spiramycin levels were about 24-fold the serum level (n = 6 patients), when the BAL/serum glucose ratios were used as the dilution estimate. Alveolar macrophage levels ranged from 17 to 210 mg/l (n = 6 patients receiving 500 mg spiramycin infusion). These results are consistent with the in-vitro data.
A Pilot Clinical Study of Treatment Guided by Personalized Tumorgrafts in Patients with Advanced Cancer (2011)

Abstract Patients with many advanced solid cancers have very poor prognosis, and improvements in life expectancy are measured only in months. We have recently reported the remarkable clinical outcome of a patient with advanced, gemcitabine-resistant, pancreatic cancer who was later treated with DNA-damaging agents, on the basis of the observation of significant activity of this class of drugs against a personalized tumorgraft generated from the patient's surgically resected tumor. Here, we extend the approach to patients with other advanced cancers. Tumors resected from 14 patients with refractory advanced cancers were propagated in immunodeficient mice and treated with 63 drugs in 232 treatment regimens. An effective treatment regimen in the xenograft model was identified for 12 patients. One patient died before receiving treatment, and the remaining 11 patients received 17 prospectively guided treatments. Fifteen of these treatments resulted in durable partial remissions. In 2 subjects, no effective treatments were found. Overall, there was a remarkable correlation between drug activity in the model and clinical outcome, both in terms of resistance and sensitivity. The data support the use of the personalized tumorgraft model as a powerful investigational platform for therapeutic decision making and to efficiently guide cancer treatment in the clinic.

Interleukin-1beta and tumour necrosis factor-alpha impede neutral lipid turnover in macrophage-derived foam cells (2008)

IL-1beta and TNF-alpha enhance macrophage foam cell formation, in part by inhibition of macrophage intracellular lipid catabolism. If present in vivo, these mechanisms will further augment the pro-atherogenic properties of the two cytokines.
<title>Design of eye movement monitoring system for practical environment</title> (1991)

This paper describes improved design and implementation of real-time eye movement data acquisition and monitoring system. The main object of the system design is to provide a more practical environment, which allows less restriction on subjects'' head displacement and eliminates tedious optical mirror adjustments. An eye-mark recorder is used as the input device to measure the x-y coordinates of eye movements relative to a subject''s head. In addition, the continuous front view image is taken by a video camera set on the subject''s head. A CRT display is placed in front of the subject. The subject is shown visual objects displayed on the screen and asked to avoid deliberate head motion. Eight infrared LED reference points invisible to the subject are fixed on the screen. These points are used to calibrate the head displacement. First, a set of nonlinear photogrammetric equations including trigonometric functions are developed to relate the reference points to the camera displacements. Second, the equations are linearized for faster calculations. The errors caused by the approximation are evaluated. It is concluded that the linear equations give satisfactory results considering the physical configurations. A set of typical experiment results are shown to demonstrate the system performance.

Aberrant splicing and protease involvement in mesothelin release from epithelioid mesothelioma cells (2008)

Elevated amounts of soluble mesothelin-related proteins (SMRP) have already been reported in sera and pleural effusions from mesothelioma patients, providing a useful diagnostic marker for malignant pleural mesothelioma (MPM). However, the origin of SMRP is not yet understood. Production of SMRP could be related to abnormal splicing events leading to synthesis of a secreted protein (release) or to an enzymatic cleavage from membrane-bound mesothelin (ectodomain shedding). To test these hypotheses, we used a panel of mesothelioma cells established in culture from pleural effusions of MPM patients. Our in vitro results confirmed specific mesothelin expression and SMRP production in supernatants from epithelioid MPM cell lines, thus providing a relevant cellular model to study soluble mesothelin production mechanisms. The expression of mesothelin-encoding RNA variants was screened by reverse transcription-polymerase chain reaction experiments. Protease involvement in mesothelin cleavage from the cellular surface was investigated by treatment of MPM cells with GM6001, a broad-spectrum MMP- and ADAM-family inhibitor. GM6001 treatment significantly impaired SMRP production by MPM cell lines, in favor of an enzymatic-mediated shedding process. In addition, a splice variant transcript of mesothelin (variant 3) was detected in these MPM cell lines, in accordance with the release of a secreted part of the protein. Our results indicate that both mechanisms could be implicated in soluble mesothelin production by epithelioid mesothelioma cells.

DNA Analysis by Fluorescence Quenching Detection (2003)

The analysis of human genetic variations such as single nucleotide polymorphisms (SNPs) has great applications in genome-wide association studies of complex genetic traits. We have developed an SNP genotyping method based on the primer extension assay with fluorescence quenching as the detection. The template-directed dye-terminator incorporation with fluorescence quenching detection (FQ-TDI) assay is based on the observation that the intensity of fluorescent dye R110- and R6G-labeled acycloterminators is universally quenched once they are incorporated onto a DNA oligonucleotide primer. By comparing the rate of fluorescence quenching of the two allelic dyes in real time, we have extended this method for allele frequency estimation of SNPs in pooled DNA samples. The kinetic FQ-TDI assay is highly accurate and reproducible both in genotyping and in allele frequency estimation. Allele frequencies estimated by the kinetic FQ-TDI assay correlated well with known allele frequencies, with an r(2) value of 0.993. Applying this strategy to large-scale studies will greatly reduce the time and cost for genotyping hundreds and thousands of SNP markers between affected and control populations.

In this letter we present a new architecture for a polar decoder using a reduced complexity successive cancellation decoding algorithm. This novel fully-unrolled, deeply-pipelined architecture is capable of achieving a coded throughput of over 237 Gbps for a (1024,512) polar code implemented using an FPGA. This decoder is two orders of magnitude faster than state-of-the-art polar decoders.
Critical comparison of sample preparation strategies for shotgun proteomic analysis of formalin-fixed, paraffin-embedded samples: insights from liver tissue (2014)

These results highlight that diverse sample preparation strategies provide significantly different proteomic information, and present typical biases that should be taken into account when dealing with FFPE samples. When a sufficient amount of tissue is available, the complementary use of different methods is suggested to increase proteome coverage and depth.
Adoptive transfer and selective reconstitution of streptamer‐selected cytomegalovirus‐specific CD8+ T cells leads to virus clearance in patients after allogeneic peripheral blood stem cell transplantation (2010)

Taken together, the streptamer technology offers the advantage of selecting virus-specific CD8+ T cells at GMP level for adoptive T-cell transfer, thus inducing long-lasting specific CD8+ T-cell responses without increasing the risk for graft-versus-host disease.
A novel ultra-wideband 80 GHz FMCW radar system for contactless monitoring of vital signs (2015)

In this paper an ultra-wideband 80 GHz FMCW-radar system for contactless monitoring of respiration and heart rate is investigated and compared to a standard monitoring system with ECG and CO(2) measurements as reference. The novel FMCW-radar enables the detection of the physiological displacement of the skin surface with submillimeter accuracy. This high accuracy is achieved with a large bandwidth of 10 GHz and the combination of intermediate frequency and phase evaluation. This concept is validated with a radar system simulation and experimental measurements are performed with different radar sensor positions and orientations.
Colloidal Suspensions of Nanometer‐Sized Mesoporous Silica (2007)

Abstract Nanometer‐sized surfactant‐templated materials are prepared in the form of stable suspensions of colloidal mesoporous silica (CMS) consisting of discrete, nonaggregated particles with dimensions smaller than 200 nm. A high‐yield synthesis procedure is reported based on a cationic surfactant and low water content that additionally enables the adjustment of the size range of the individual particles between 50 and 100 nm. Particularly, the use of the base triethanolamine (TEA) and the specific reaction conditions result in long‐lived suspensions. Dynamic light scattering reveals narrow particle size distributions in these suspensions. Smooth spherical particles with pores growing from the center to the periphery are observed by using transmission electron microscopy, suggesting a seed‐growth mechanism. The template molecules could be extracted from the nanoscale mesoporous particles via sonication in acidic media. The resulting nanoparticles give rise to type IV adsorption isotherms revealing typical mesopores and additional textural porosity. High surface areas of over 1000 m 2 g –1 and large pore volumes of up to 1 mL g –1 are obtained for these extracted samples.
Effects of Nicorandil Administration on Survival Rate and Arrhythmias during Reperfusion in Anesthetized Rabbits (2001)

The aim was to study the effects of nicorandil (an ATP-sensitive K+ channel opener) and tolbutamide (an ATP-sensitive K+ channel blocker) on reperfusion-induced arrhythmias in pentobarbitone and ketamine anesthetized rabbits. Arrhythmias were induced by reperfusion for 20 min following a 15-min ligation of the left main coronary artery with a silk ligature. Rabbits were pretreated with nicorandil (0.47, 0.93 or 1.86 mg/kg i.v.) or tolbutamide (180 mg/kg i.p.) or vehicle (dimethylsulfoxide/saline) before the coronary artery occlusion. In the control group (n = 10), only 60% of the animals survived during reperfusion. Intravenous pretreatment with 0.47, 0.93 or 1.86 mg/kg of nicorandil increased the survival rate to 86% (n = 7), 75% (n = 8) and 86% (n = 7), respectively. Nicorandil pretreatment significantly decreased the incidence and duration of reperfusion-induced life-threatening arrhythmias and increased the number of animals that survived without developing any arrhythmia. Tolbutamide pretreatment was associated with a decreased survival rate of 50% (n = 12) and an increase in the incidence and duration of reperfusion-induced arrhythmias. Pretreatment with nicorandil may result in protection against reperfusion-induced arrhythmias and increased survival in anesthetized rabbits.
Enhanced anti-tumor effect of an IFN-gamma-EGF fusion protein. (1997)

The novel fusion proteins harboring human or mouse interferon combined with epidermal growth factor receptor binding domain were constructed using methods of genetic and protein engineering. The fusion proteins were assayed to retain complete antiviral activities. The EGF receptor binding moiety of the fusion proteins exhibited competitive binding against 125I-EGF for EGF receptors on A431 cells. The fusion proteins were shown to be more potent in inhibiting the growth of cultured target carcinoma cells than interferon-gamma alone. Experimental data derived from mouse B16 malignant melanoma models indicates that the weight of tumor in mice treated with IFN fusion proteins was significantly smaller than that of mice treated with interferon-gamma alone. The work here is unprecedented in the world and provides a reliable evidence to support the upcoming clinical employment of a class of interferons that specifically target tumor cell.
TNER: a novel background error suppression method for mutation detection in circulating tumor DNA (2018)

Ultra-deep next-generation sequencing of circulating tumor DNA (ctDNA) holds great promise as a tool for the early detection of cancer and for monitoring disease progression and therapeutic responses. However, the low abundance of ctDNA in the bloodstream coupled with technical errors introduced during library construction and sequencing complicates mutation detection. To achieve high accuracy of variant calling via better distinguishing low-frequency ctDNA mutations from background errors, we introduce TNER (Tri-Nucleotide Error Reducer), a novel background error suppression method that provides a robust estimation of background noise to reduce sequencing errors. The results on both simulated data and real data from healthy subjects demonstrate that the proposed algorithm consistently outperforms a current, state-of-the-art, position-specific error polishing model, particularly when the sample size of healthy subjects is small. TNER significantly enhances the specificity of downstream ctDNA mutation detection without sacrificing sensitivity. The tool is publicly available at https://github.com/ctDNA/TNER .
