Technical and Financial Feasibility Analysis of Distributed Bioprocessing Using Regional Biomass Pre-Processing Centers (2007)

Research indicates that large biorefineries capable of handling 5000-10000MT of biomass per day are necessary to achieve process economies. However, such large biorefineries also entail increased costs of biomass transportation and storage, high transaction costs of contracting with a large number of farmers for biomass supply, potential market power issues, and local environmental impacts. We propose a network of regional biomass preprocessing centers (RBPC) that form an extended biomass supply chain feeding into a biorefinery, as a way to address these issues. The RBPC, in its mature form, is conceptualized as a flexible processing facility capable of pre-treating and converting biomass into appropriate feedstocks for a variety of final products such as fuels, chemicals, electricity, and animal feeds. We evaluate the technical and financial feasibility of a simple RBPC that uses ammonia fiber expansion pretreatment process and produces animal feed along with biorefinery feedstock.
An Efficient Fluorescent Probe for Ratiometric pH Measurements in Aqueous Solutions (2004)

Just as litmus paper changes from red to blue with an increase in pH, so the fluorescence emission of the oxazole derivative 1 shifts from green to blue. Ratiometric measurements of the fluorescence emissions of the two species, after one- or two-photon excitation, allow 1 to be employed as a pH sensor over the mid-pH range.
A Truncated Herpes Simplex Virus Thymidine Kinase Phosphorylates Thymidine and Nucleoside Analogs and Does Not Cause Sterility in Transgenic Mice (1995)

Dividing eukaryotic cells expressing the herpes simplex virus type 1 thymidine kinase (TK) gene are sensitive to the cytotoxic effect of nucleoside analogs such as acyclovir or ganciclovir (GCV). Transgenic mice with cell-targeted expression of this conditional toxin have been used to create animals with temporally controlled cell-specific ablation. In these animal models, which allow the study of the physiological importance of a cell type, males are sterile. In this study, we showed that this phenomenon is due to testis-specific high-level expression of short TK transcripts initiated mainly upstream of the second internal ATG of the TK gene. This expression is DNA methylation independent. To obtain a suicide gene that does not cause male infertility, we generated and analyzed the properties of a truncated TK (delta TK) lacking the sequences upstream of the second ATG. We showed that when expressed at sufficient levels, the functional properties of delta TK are similar to those of TK in terms of thymidine or GCV phosphorylation. This translated into a similar GCV-dependent toxicity for delta TK- or TK-expressing cells, both in vitro and in transgenic mice. However, delta TK behaved differently from TK in two ways. First, it did not cause sterility in delta TK transgenic males. Second, low-level delta TK RNA expression did not confer sensitivity to GCV. The uses of delta TK in cell-specific ablation in transgenic mice and in gene therapy are discussed.
Treatment of multiple, multiform actinic keratoses on the head with imiquimod 5% cream (2009)

The objective of this non-controlled interventional clinical study was to evaluate the efficacy of imiquimod in the treatment of fields with multiple, multiform AK. 180 office-based dermatological practices in Germany participated. Patients with clinically typical, visible AK lesions on the head were treated with 5% imiquimod cream 3 times per week for 4 weeks followed by a 4 week treatment pause. If lesions were still present, a second treatment course of treatment (COT) was given. Complete clearance rate, i.e. no clinically visible AK lesions in the treatment area, was the main outcome measure. 829 patients were enrolled. The complete clearance rate was 40.5% after the first COT and 68.9% overall. Altogether, 85.4% of the 7,427 baseline lesions were cleared. Patients with hyperkeratotic/hypertrophic lesions showed comparable responses. Local skin reactions were the most commonly reported adverse effects, causing discontinuation in only 4 patients. Severity of the local skin reactions was a strong predictor of the outcome. Patients with multiple multiform AK on the head can be successfully and safely treated with topical imiquimod in daily practice. Assurance of patient understanding that treatment success is closely correlated to proper drug administration is important.
Large scale industrialized cell expansion: producing the critical raw material for biofabrication processes (2015)

Cellular biomanufacturing technologies are a critical link to the successful application of cell and scaffold based regenerative therapies, organs-on-chip devices, disease models and any products with living cells contained in them. How do we achieve production level quantities of the key ingredient-'the living cells' for all biofabrication processes, including bioprinting and biopatterning? We review key cell expansion based bioreactor operating principles and how 3D culture will play an important role in achieving production quantities of billions to even trillions of anchorage dependent cells. Furthermore, we highlight some of the challenges in the field of cellular biomanufacturing that must be addressed to achieve desired cellular yields while adhering to the key pillars of good manufacturing practices-safety, purity, stability, potency and identity. Biofabrication technologies are uniquely positioned to provide improved 3D culture surfaces for the industrialized production of living cells.
A Synthetic Lipopolysaccharide-Binding Peptide Based on Amino Acids 27–39 of Serum Amyloid P Component Inhibits Lipopolysaccharide-Induced Responses in Human Blood (1998)

LPS-binding proteins in plasma play an important role in modifying LPS toxicity. Significant properties have already been attributed to the LPS-binding protein (LBP). It accelerates LPS toxicity as well as incorporation into high-density lipoproteins, leading to neutralization of LPS in serum. A search for other LPS-binding components in serum, using LPS-coated magnetic beads, revealed a new LPS-binding protein. N-terminal microsequencing identified this protein as serum amyloid P component (SAP). Purified SAP bound to smooth and rough types of LPS via the lipid A part. SAP inhibited the binding of FITC-labeled ReLPS (LPS from Salmonella minnesota strain R595) to human monocytes and the ReLPS-induced priming of the oxidative burst of human neutrophils only in the presence of low concentrations of LBP. In search for the LPS binding site of SAP, we found that pep27-39, a 13-mer peptide consisting of amino acids 27-39 of SAP, competitively inhibited the binding of LPS to SAP. In addition, pep27-39 significantly inhibited ReLPS-induced responses in phagocytes in the presence of serum, as well as in human whole blood. Carboxamidomethylated pep27-39 showed an even more pronounced reduction of the ReLPS-induced priming of phagocytes in human blood. Performing gel filtration of FITC-labeled ReLPS incubated with soluble CD14, we showed that SAP could not prevent binding of LPS to soluble CD14, in contrast to pep27-39. The ability of pep27-39 to antagonize specifically the effects of LPS in the complex environment of human blood suggests that pep27-39 may be a novel therapeutic agent in the treatment of gram-negative sepsis.
Altered left atrial compliance after atrial appendectomy. Influence on left atrial and ventricular filling. (1993)

Previous studies have shown regional differences in atrial distensibility. We studied 12 open-chest dogs to test the hypothesis that left atrial compliance is decreased after removal of the left atrial appendage and to determine the effect of altered atrial compliance on atrial reservoir and conduit function. Sonomicrometer crystal pairs were used to measure the long- and short-axis diameters of the left atrium over a wide range of intracardiac pressures and volumes obtained by intravenous hetastarch infusion both before and after suture ligation of the left atrial appendage (appendectomy). Pulmonary venous flow was measured with an ultrasonic flowmeter, and transmitral flow velocities were measured with transesophageal Doppler echocardiography. After appendectomy, the diastolic pressure-volume relation was shifted upward and to the left in six of seven dogs. The mean dynamic stiffness constant of the left atrial diastolic pressure-volume relation was significantly greater after appendectomy than before (0.20 +/- 0.11 [mean +/- SD] versus 0.14 +/- 0.08 ml-1, p < 0.01); the mean y intercept was slightly, but significantly, less after appendectomy (0.6 +/- 0.3 versus 1.3 +/- 0.6 mm Hg, p < 0.05). The left atrial reservoir volume (maximum minus minimum left atrial volume) was significantly less after appendectomy at matched left atrial pressures. The systolic to diastolic flow integral ratio of pulmonary venous flow (JFTI/KFTI), an index of the relative reservoir to conduit functions of the left atrium, increased significantly with volume infusion only before appendectomy; at matched left atrial pressure, JFTI/KFTI was significantly less afterwards.(ABSTRACT TRUNCATED AT 250 WORDS)
Hands on the wheel: A Dataset for Driver Hand Detection and Tracking (2018)

The ability to detect, localize and track the hands is crucial in many applications requiring the understanding of the person behavior, attitude and interactions. In particular, this is true for the automotive context, in which hand analysis allows to predict preparatory movements for maneuvers or to investigate the driver's attention level. Moreover, due to the recent diffusion of cameras inside new car cockpits, it is feasible to use hand gestures to develop new Human-Car Interaction systems, more user-friendly and safe. In this paper, we propose a new dataset, called Turms, that consists of infrared images of driver's hands, collected from the back of the steering wheel, an innovative point of view. The Leap Motion device has been selected for the recordings, thanks to its stereo capabilities and the wide view-angle. Besides, we introduce a method to detect the presence and the location of driver's hands on the steering wheel, during driving activity tasks.
Optimization of idle current in envelope tracking power amplifier for efficiency and linearity (2016)

We have investigated the efficiency and distortion behavior of an envelope tracking (ET) power amplifier (PA) according to the idle current. A two-stage PA is implemented using an InGaP/GaAs heterojunction bipolar transistor process and only the collector bias voltage of the power stage of the PA is modulated by a supply modulator. The gain of the power stage is decreased due to the saturated operation in the ET mode and the power burden of the drive stage is increased, lowering the overall efficiency of the ET PA. Through the idle current optimization of the power stage of the ET PA, the burden of the drive stage is reduced and the overall efficiency of the ET PA is enhanced. The intermodulation distortions (IMDs) of the ET PA change according to the idle current. The optimum linearity performance is achieved at the idle current where the magnitudes of IMD3 and IMD5 of the ET PA are low with a similar value. It is found that the optimal idle current for the high efficiency and linearity are identical. The optimized ET PA performs a power-added efficiency of 44.3% and an evolved universal terrestrial radio access adjacent channel leakage ratio of -35.2 dBc at an average power of 27 dBm and operating frequency of 1.85 GHz for a long term evolution signal having a peak-to-average power ratio of 7.5 dB, a bandwidth of 10 MHz, and a 16-quadrature amplitude modulation.
IFN-λ: Novel Antiviral Cytokines (2006)

The first line of defense against viral infections is mediated by interferons (IFN)s, which are produced rapidly by the infected host. Type I IFNs (IFN-alpha/beta) are known to combat viruses both directly by inhibiting viral replication in the cells and indirectly by stimulating the innate and adaptive immune responses. Recently, a novel class of cytokines was discovered and named IFN-lambda (alternatively type III IFN or interleukin-28/29 [IL- 28/29]), based on IFN-like antiviral activity and induction of typical IFN-inducible genes. Here, we review the literature on IFN-lambda and discuss the current knowledge of the functions and mechanisms of action of IFN-lambda.
In Situ Synthesis of ZrO 2 /ZrW 2 O 8 Composites With Near‐Zero Thermal Expansion (2007)

In this paper, ZrO 2 and WO 3 were used as the raw materials to prepare ZrO 2 /ZrW 2 O 8 composites by in situ reaction method and the thermal expansion property of the composites was studied. This novel method included a heating step up to 1473 K for 24 h, which combines the synthesizing and sintering of ZrW 2 O 8 . The result indicates that ZrO 2 /ZrW 2 O 8 composite shows near‐zero thermal expansion when the weight ratio of ZrO 2 and WO 3 is 2.5:1. Compared with composites prepared previously by non‐reactive sintering of ZrO 2 and ZrW 2 O 8 , the composites show higher relative density and lower porosity.

Molecular cloning of the muscle gene unc-22 in Caenorhabditis elegans by Tc1 transposon tagging. (1986)

The previously described mutator system of Caenorhabditis elegans var. Bergerac has as one of its targets unc-22, a previously uncloned gene on chromosome IV important in assembly and function of the body wall musculature. By assuming that the mutator activity involved transposition of the repetitive element Tc1 into the unc-22 gene we have succeeded both in cloning the unc-22 gene and in demonstrating that Tc1 transposition is the principal basis of the mutator activity in the Bergerac strain. Although germ-line excision of Tc1 is sensitive to genetic background, somatic excision appears to be less so, suggesting that Tc1 movement is controlled differently in germ-line and somatic tissue. The availability of a transposon-based mutator system should aid in the cloning of additional genes in C. elegans, and the particular properties of this Tc1 system may provide information about the control of transposable element activity more generally.

Epstein-Barr Virus Regulates c-MYC, Apoptosis, and Tumorigenicity in Burkitt Lymphoma (1999)

Loss of the Epstein-Barr virus (EBV) genome from Akata Burkitt lymphoma (BL) cells is coincident with a loss of malignant phenotype, despite the fact that Akata and other EBV-positive BL cells express a restricted set of EBV gene products (type I latency) that are not known to overtly affect cell growth. Here we demonstrate that reestablishment of type I latency in EBV-negative Akata cells restores tumorigenicity and that tumorigenic potential correlates with an increased resistance to apoptosis under growth-limiting conditions. The antiapoptotic effect of EBV was associated with a higher level of Bcl-2 expression and an EBV-dependent decrease in steady-state levels of c-MYC protein. Although the EBV EBNA-1 protein is expressed in all EBV-associated tumors and is reported to have oncogenic potential, enforced expression of EBNA-1 alone in EBV-negative Akata cells failed to restore tumorigenicity or EBV-dependent down-regulation of c-MYC. These data provide direct evidence that EBV contributes to the tumorigenic potential of Burkitt lymphoma and suggest a novel model whereby a restricted latency program of EBV promotes B-cell survival, and thus virus persistence within an immune host, by selectively targeting the expression of c-MYC.
Expression of the Wilms' Tumor Gene WT1 in Solid Tumors and Its Involvement in Tumor Cell Growth (1999)

To determine the role of the Wilms' tumor gene WT1 in tumorigenesis of solid tumors, expression of the WT1 gene was examined in 34 solid tumor cell lines (four gastric cancer cell lines, five colon cancer cell lines, 15 lung cancer cell lines, four breast cancer cell lines, one germ cell tumor cell line, two ovarian cancer cell lines, one uterine cancer cell line, one thyroid cancer cell line, and one hepatocellular carcinoma cell line) by means of quantitative reverse transcriptase-polymerase chain reaction. WT1 gene expression was detected in three of the four gastric cancer cell lines, all of the five colon cancer cell lines, 12 of the 15 lung cancer cell lines, two of the four breast cancer cell lines, the germ cell tumor cell line, the two ovarian cancer cell lines, the uterine cancer cell line, the thyroid cancer cell line, and the hepatocellular carcinoma cell line. Therefore, of the 34 solid tumor cell lines examined, 28 (82%) expressed WT1. Three cell lines expressing WT1 (gastric cancer cell line AZ-521, lung cancer cell line OS3, and ovarian cancer cell line TYK-nu) were further analyzed for mutations and/or deletions in the WT1 gene by means of single-strand conformation polymorphism analysis. However, no mutations or deletions were detected in the region of the WT1 gene ranging from the 3' end of exon 1 to exon 10 (the WT1 gene consists of 10 exons) in these three cell lines. Furthermore, when AZ-521, OS3, and TYK-nu cells were treated with WT1 antisense oligomers, the growth of these cells was significantly inhibited in association with a reduction in WT1 protein levels. Furthermore, constitute expression of the transfected WT1 gene in cancer cells inhibited the antisense effect of WT1 antisense oligomer on cell growth. These results indicated that the WT1 gene plays an essential role in the growth of solid tumors and performs an oncogenic rather than a tumor-suppressor gene function.
Antigenic variation of Borrelia hermsii. (1982)

At least 24 different serotypes were detected in populations of Borrelia hermsii that originated from a single organism. These serotypes were identified by staining with specific fluoresceinated antisera prepared against cloned populations of living organisms of each type. In the order of decreasing frequency, the 10 types more often encountered were 7, which was clearly dominant, and 2, 17, 24, 13, 2, 1, 21, 11, and 12. Each of the 24 types were shown to change to 7 or more other serotypes. Spirochetemia in mice was persistent, and relapses occurred when the concentration of organisms was sufficient for detection by visual means. After mice were inoculated with a single organism, peak spirochetemia usually occurred on day 4, after which clearance of organisms occurred, and an apparently pure population was replaced by a mixed population consisting of as many as seven variants. These types persisted for 2-3 d before being replaced by other types. Conversions occurred constantly and were independent of relapses. The rate of conversion in mice treated with cyclophosphamide to delay antibody production was comparable to that of controls. Spontaneous conversion was clearly demonstrated in tubes of fortified Kelly's medium inoculated with a single organism of type 7 or 21. 11 different variants appeared in eight cultures of type 21 by the time growth had reached 4 X 10(6)-10(7) organisms/ml. The rate of spontaneous change was estimated to be or approximately 10(-4)-10(-3) per cell per generation.
