Lack of association between serotonin transporter gene promoter variants and autistic disorder in two ethnically distinct samples (2000)

Family-based studies performed to date provide conflicting evidence of linkage/association between autistic disorder and either the “short” [Cook et al., 1997: Mol Psychiatry 2:247–250] or the “long” [Klauck et al., 1997: Hum Mol Genet 6:2233–2238] allele of a polymorphic repeat located in the serotonin transporter (5-HTT) gene promoter region, affecting 5-HTT gene expression [Lesch et al., 1996: Science 274:1527–1531]. The present study was designed to assess linkage and linkage disequilibrium in two new ethnically distinct samples of families with primary autistic probands. The 5-HTT promoter repeat was genotyped in 54 singleton families collected in Italy and in 32 singleton and 5 multiplex families collected in the U.S.A., yielding a total sample of 98 trios. Linkage/association between 5-HTT gene promoter alleles and autistic disorder was assessed using the transmission/disequilibrium test (TDT) and the haplotype-based haplotype relative risk (HHRR). Both the Italian and the American samples, either singly or combined, displayed no evidence of linkage/association between 5-HTT gene promoter alleles and autistic disorder. Our findings do not support prominent contributions of 5-HTT gene variants to the pathogenesis of idiopathic infantile autism. Heterogeneity in pathogenetic mechanisms underlying the disease may require that linkage/association studies be targeted toward patient subgroups isolated on the basis of specific biochemical markers, such as serotonin (5-HT) blood levels.

Oilfield metal naphthenate formation and mitigation measures: a review (2019)

Abstract Process facilities for the separation of hydrocarbons from produced water in the oilfield are critical to flow assurance, product quality and environmental compliance. The formation of metal naphthenates, which are emulsion stabilizers and equipment foulers, is deleterious to performance and integrity of these processes and facilities. Manual removal of deposits of these organic salts formed at the oil–water interface during separation processes is difficult and expensive; hence, the best operational option is inhibition. The conventional method for the inhibition of metal naphthenates, which relies on suppressing the deprotonation of naphthenic acids by common ion effect, is no longer tenable because it exacerbates internal corrosion problems in topside facilities. Current industry focus is on the development of effective surface active agents for inhibition of naphthenates. There are a plethora of chemical compounds with naphthenate inhibition potential such as sulphonates, phosphate esters, aminated phosphonates and sulphosuccinates, but compatibility issues make the choice of inhibitor a complicated process. In this paper, the drivers and mechanism of oilfield metal naphthenate formation are reviewed. Surfactants for oilfield metal naphthenate inhibition and the mechanisms of inhibition are highlighted with a view to process optimization.
Bridging the gap: The perceptions of athletic directors and coaches regarding nonrevenue program discontinuation decisions (2011)

The purpose of this study was to explore the perceptions of athletic directors and coaches regarding wrestling program discontinuation decisions. In the past few decades, an alarming number of NCAA men’s wrestling programs have been eliminated throughout the United States (Student-athlete, 2006). Historically, the educational value offered through intercollegiate athletics was enough to justify financial funding of these programs; however, the marked trend toward the discontinuation of sports that are nonrevenue in nature support the notion that this justification may no longer be sufficient in today’s big-time intercollegiate athletic environment. In order to ensure the sustainability of programs that do not have the financial lure of big-time football and basketball, it is essential for primary program advocates (coaches) to understand the criteria employed by athletic directors when eliminating these programs. Utilizing a multiple-embedded case study (n = 4) with the use of survey, athletic directors (n = 20) and wrestling head coaches (n = 24) of Football Bowl Subdivision universities who have sponsored wrestling within the past ten years were studied in order to explore perceptions regarding the criteria utilized in programtermination decisions. Findings suggest that athletic directors utilize budget shortages and financial strain of the program as primary discontinuation criteria followed by gender equity implications, success on the mat, and regional sport popularity. In contrast, the coaches indicated they felt gender equity, regional sport popularity, donor support, athletes’ actions off the mat, and athletes’ academic performance were the primary reasons for program eliminations. Thus, the results illustrated that athletic directors and coaches had varying perceptions for the reasons why nonrevenue programs such as men’s wrestling are eliminated. The study provides a unique opportunity to understand the underlying reasons why men’s wrestling programs are eliminated, and what coaches of nonrevenue sports might do to sustain their programs.
Erasure Code-Based Low Storage Blockchain Node (2018)

The concept of a decentralized ledger usually implies that each node of a blockchain network stores the entire blockchain. However, in the case of popular blockchains, which each weigh several hundreds of GB, the large amount of data to be stored can incite new or low-capacity nodes to run lightweight clients. Such nodes do not participate to the global storage effort and can result in a centralization of the blockchain by very few nodes, which is contrary to the basic concepts of a blockchain. To avoid this problem, we propose new low storage nodes that store a reduced amount of data generated from the blockchain by using erasure codes. The properties of this technique ensure that any block of the chain can be easily rebuilt from a small number of such nodes. This system should encourage low storage nodes to contribute to the storage of the blockchain and to maintain decentralization despite of a globally increasing size of the blockchain. This system paves the way to new types of blockchains which would only be managed by low capacity nodes.
Concatenated decoding with a reduced-search BCJR algorithm (1998)

We apply two reduced-computation variants of the BCJR algorithm to the decoding of serial and parallel concatenated convolutional codes. One computes its recursions at only M states per trellis stage; one computes only at states with values above a threshold. The threshold scheme is much more efficient, and it greatly reduces the computation of the BCJR algorithm. By computing only when the channel demands it, the threshold scheme reduces the turbo decoder computation to one-four nodes per trellis stage after the second iteration.
Fabrication of a poly(dimethylsiloxane) membrane with well-defined through-holes for three-dimensional microfluidic networks (2009)

We report a simple method for the fabrication of a poly(dimethylsiloxane) (PDMS) membrane with through-holes by blowing a residual prepolymer away from a photoresist (PR)-patterned Si wafer. The fabrication method for the perforated polymer membrane is crucial to achieve both complicated three-dimensional microfluidic devices and polymer sieve sheets. This method has several advantages over the previous methods in that we can repeatedly make the well-defined holes on the PDMS membranes even if the excess prepolymer remains on the PR mold after spincoating at a relatively low rpm. In addition, the desired pattern can be selectively perforated from the whole wafer even if the mold is fabricated by single-step lithography.
On the performance of coded low spreading gain DS-CDMA systems with random spreading in sequences multipath Rayleigh fading channels (2001)

Next generation wireless systems based on variable spreading gain (VSG) DS-CDMA offer variable data-rates while keeping constant the signal envelope and bandwidth. For high data-rate services the SG can be as low as 2 chips per transmitted (coded) symbol, which deteriorates the system performance because it enhances the inter-path interference (IPI). Different self-interference cancellation (SIC) approaches have been examined in uncoded VSG-CDMA systems to combat IPI. We examine the effect of low SG in practical VSG-CDMA systems, which use convolutional and turbo coding and concatenated short orthogonal and long pseudo-random spreading. We show that the performance of the conventional RAKE receiver degrades only moderately for SG as low as 4 chips per transmitted symbol for BER/spl ges/10/sup -6/ and for different multipath profiles. In this range of interest the error floor typical to turbo codes is observed due to the free distance properties of these codes rather than the effect of IPI. This suggests that the increased complexity of SIC schemes is justified only for very high data-rates.
Synthesis of Mercapto-(+)-methamphetamine Haptens and Their Use for Obtaining Improved Epitope Density on (+)-Methamphetamine Conjugate Vaccines (2011)

This study reports the synthesis of the mercapto-hapten (S)-N-(2-(mercaptoethyl)-6-(3-(2-(methylamino)propyl)phenoxy)hexanamide [3, (+)-METH HSMO9] and its use to prepare METH-conjugated vaccines (MCV) from maleimide-activated proteins. MALDI-TOF mass spectrometry analysis of the MCV synthesized using 3 showed there was a high and controllable epitope density on two different carrier proteins. In addition, the MCV produced a substantially greater immunological response in mice than previous METH haptens, and a monoclonal antibody generated from this MCV in mice showed a very high affinity for (+)-METH (K(D) = 6.8 nM). The efficient covalent coupling of (+)-METH HSMO9 to the activated carrier proteins suggests that this approach could be cost-effective for large-scale production of MCV. In addition, the general methods described for the synthesis of (+)-METH HSMO9 (3) and its use to synthesize MCV will be applicable for conjugated vaccines of small molecules and other substances of abuse such as morphine, nicotine, and cocaine.
Rituximab-CHOP Significantly Improve the Response of Advanced Extranodal Marginal Zone B-Cell Lymphoma of the Mucosa-Associated Lymphoid Tissue (MALT Lymphoma). (2006)

Abstract Introduction: MALT lymphoma, even if advanced stage, is known to have indolent outcome. However, previous reports showed that chemotherapy only could not improve the disease progression. Recently a few reports demonstrated rituximab monotherapy could not acquired enough response for the patients with advanced MALT lymphoma. We retrospectively analyzed outcomes of patients with advanced MALT lymphoma treated with rituximab monotherapy or rituximab-CHOP like regimen (R-CHOP), and discussed about the treatment of this entity. We also performed the immunohistochemcal study of bcl-2 and reverse-transcription polymerase-chain-reaction (RT-PCR) analysis of API2-MALT1, and evaluate whether the existence of bcl-2 or API2-MALT1 makes any influence on the response to rituximab treatments. Patients and methods: Between October 2001 and October 2005, 106 patients (pts) were treated in our institute and 21 pts with advance-staged MALT lymphomas were included in this study. Advanced stage with GI tract MALT lymphoma was defined as a stage II1+2 or IV according to Lugano staging system. On the other hand, advanced stage with non-GI tract lymphoma was defined as a stage III or IV. In this study, immunohistochemical staining with bcl-2 and RT-PCR analysis of API2-MALT1 were performed. Results: Twenty-one pts (12 men and 9 women) were treated with rituximab treatment and a median age was 65 years (27–83 years). Stage II+III pts and IV pts were 9 pts (22.9%) and 12 pts (57.1%), respectively. Three of five HP-positive pts did not respond antibiotic therapy. The remaining HP-negative 16 pts received rituximab therapy as first line treatment. Of the patients who required systemic chemotherapy, 16 pts were treated with R-CHOP; 5 pts with rituximab monotherapy. The overall response rates (ORR) were 100% (CR rate = 62.5%) in the R-CHOP group, 60% (CR rate = 60%) in rituximab monotherapy, respectively. The median follow up was 2.2 years. Relapse rate were 6.2% (1/17) in the R-CHOP group, 40% (2/5) in the rituximab monotherapy, respectively. Bcl-2 was expressed in 11 of 17 tissues tested, and CR rates were 63.3/37% in bcl-2 +/− patients. Grade 3 to 4 cytopenia was observed in 87.5% of patients in R-CHOP group, but not in rituximab monotherapy. Grade3 to 4 non-hematological toxicity was not seen in both groups. Conclusion: R-CHOP exhibited impressive efficacy with one failure among 17 patients. ORR was also significantly better in R-CHOP group than in rituximab monotherapy. The efficacy of rituximab monotherapy was similar to previous reports. These results strongly suggest that R-CHOP improves the response of advance-staged MALT lymphoma. In this study, bcl-2 and API2-MALT1 did not contribute to response to rituximab treatment. R-CHOP is expected to prolong relapse-free survival compared to rituximab monotherapy or chemotherapy only. Scince hematologic toxicity in R-CHOP group is severe, R-CVP regimen which is less toxicity may be necessary to be evaluated.
Tailoring a fluorophosphate as a novel 4 V cathode for lithium-ion batteries (2012)

Lithium-ion batteries, which have been widely used to power portable electronic devices, are on the verge of being applied to new automobile applications. To expand this emerging market, however, an electrode that combines fast charging capability, long-term cycle stability, and high energy density is needed. Herein, we report a novel layered lithium vanadium fluorophosphate, Li(1.1)Na(0.4)VPO(4.8)F(0.7), as a promising positive electrode contender. This new material has two-dimensional lithium pathways and is capable of reversibly releasing and reinserting ~1.1 Li(+) ions at an ideal 4 V (versus Li(+)/Li) to give a capacity of ~156 mAh g(-1) (energy density of 624 Wh kg(-1)). Moreover, outstanding capacity retentions of 98% and 96% after 100 cycles were achieved at 60°C and room temperature, respectively. Unexpectedly high rate capability was delivered for both charge and discharge despite the large particle size (a few microns), which promises further enhancement of power density with proper nano-engineering.
Intestinal Microbiota Distinguish Gout Patients from Healthy Humans (2016)

Current blood-based approach for gout diagnosis can be of low sensitivity and hysteretic. Here via a 68-member cohort of 33 healthy and 35 diseased individuals, we reported that the intestinal microbiota of gout patients are highly distinct from healthy individuals in both organismal and functional structures. In gout, Bacteroides caccae and Bacteroides xylanisolvens are enriched yet Faecalibacterium prausnitzii and Bifidobacterium pseudocatenulatum depleted. The established reference microbial gene catalogue for gout revealed disorder in purine degradation and butyric acid biosynthesis in gout patients. In an additional 15-member validation-group, a diagnosis model via 17 gout-associated bacteria reached 88.9% accuracy, higher than the blood-uric-acid based approach. Intestinal microbiota of gout are more similar to those of type-2 diabetes than to liver cirrhosis, whereas depletion of Faecalibacterium prausnitzii and reduced butyrate biosynthesis are shared in each of the metabolic syndromes. Thus the Microbial Index of Gout was proposed as a novel, sensitive and non-invasive strategy for diagnosing gout via fecal microbiota.

Synthesis of Fluorapatite Nanorods and Nanowires by Direct Precipitation from Solution (2006)

In natural tooth enamel fluoride is always present in the carbonated hydroxyapatite mineral and plays a key role in the prevention of tooth decay. In this study we aimed at mimicking this natural anti-caries ability of the tooth by developing new, effective anticaries materials using fluorapatite nanorods or nanowires. We therefore investigated the conditions necessary to synthesize fluorapatite nanorods of different size, shape and composition for future use either directly or indirectly, that is by incorporation into dental materials, in the treatment and prevention of caries. By controlling the chemical conditions, nanorods of desirable chemical composition and dimension were produced. The mechanism of how these structures were formed is also proposed.
Coupling of light from an LED into a very thin light guide by a coupling lens (2007)

A LED light coupler is designed with rigorous geometrical optics analysis for coupling light from a mini side white LED of 0.6mm height, the thinnest commercially available LED, into to a very thin (~0.3mm) light guide on the edge side. The ultra thin thickness of the light guide limits the application of conventional LED coupling due to short coupling efficiency. Furthermore the polychromatic spectral band of the LED excludes the use of diffractive gratings which were proposed for a nearly monochromatic LED coupling to a thin light guide. The coupler is essentially comprised of a collimator and a concentrator lens. The coupler first collimates the light from the LED and then concentrates the collimated light into the light guide. The exit surface of the coupler is additionally textured to have micro patterns in order to control the radiance profile. The coupling efficiency is improved from 50%~60% without any couplers to 86% with the proposed LED coupler.

Effect of Delayed Thrombolysis with rt-PA in a Rat Embolic Stroke Model (1994)

The effect of delayed thrombolysis with recombinant tissue plasminogen activator was tested in an embolic stroke model. The carotid territory was embolized in 103 rats with fibrin-rich clots formed and washed in polyethylene tubes. Hemispheric cerebral blood flow before and after embolization was measured by the intra arterial 133Xe injection method. At five delay times, 15-240 min after embolization, 69 animals were treated with tissue plasminogen activator, 20 mg/kg, and 34 animals with saline. Carotid angiography displayed the grade of occlusion of the cerebral arterial supply before and after treatment. Brains were fixed after 2 days, evaluated neuropathologically, and infarct volume measured. Cerebral blood flow was reduced by 56-71% after embolization. Reperfusion induced by thrombolytic therapy was demonstrated by comparing the posttreatment angiography of the pooled five treatment groups to control animals. Thrombolytic therapy significantly reduced the infarct volume and improved the prekill clinical score by up to 2 h of treatment delay, and treatment might have been beneficial even after 4 h delay. Prolonging the delay of treatment increased the infarct volume (p < 0.001, Jonck-heere-Terpstra test). Only a few hemorrhagic complications were observed. Thus, thrombolytic therapy in embolic stroke induced recanalization. The effect on clinical outcome and infarct volume was dependent on delay time.
Multiple therapeutic peptide vaccines for patients with advanced gastric cancer (2017)

We performed a clinical trial using HLA-A24-binding peptide vaccines containing a combination of novel cancer-testis antigens and anti-angiogenic peptides for advanced gastric cancer (GC). Thirty-five GC patients who had shown resistance to the standard therapy were enrolled in this clinical trial using vaccinations with a mixture of multiple peptides derived from DEPDC1, URLC10, FoxM1, Kif20A and VEGFR1. The safety, the overall survival (OS), and the immunological responses based on an ELISPOT assay were determined to assess differences in patients who were HLA-A24-positive [24(+)] and HLA-A24-negative [24(-)]. No severe adverse effects were observed except for severe skin reactions in 4 patients. The differences in OS were not significant between patients who were 24(+) and 24(-). In the 24(+) group, patients who showed T cell responses specific to antigen peptides had a tendency towards better survival than those who showed no response, especially to the DEPDC1 peptide. The patients with local skin reactions had significantly better OS than the others. Peptide vaccine therapy was found to be safe and is expected to induce specific T cell responses in patients with advanced GC. The survival benefit of peptide vaccine monotherapy may not have been shown and further trials are needed to confirm these results.
