Efficiency Records in Mesoscopic Dye‐Sensitized Solar Cells (2015)

The aim of the present review article is to show the progress achieved in the efficiency of dye-sensitized solar cells (DSSCs) by evolution in the structure and composition of the dye. After an initial brief description of DSSCs and the operating mechanism the major part of the present article is organized according to the type of dye, trying to show the logic in the variation of the dye structure in order to achieve strong binding on the surface of the layer of nanoparticulate TiO2 , efficient interfacial electron injection between the excited dye and the semiconductor, and minimization of the unwanted dark current processes. Besides metal complexes, including polypyridyls and nitrogenated macro rings, organic dyes and inorganic light harvesters such as quantum dots and perovskites have also been included in the review. The last section summarizes the current state of the art and provides an overview on future developments in the field.
The Critical Role of IL-1 Receptor-Associated Kinase 4-Mediated NF-κB Activation in Modified Low-Density Lipoprotein-Induced Inflammatory Gene Expression and Atherosclerosis (2011)

Exciting discoveries related to IL-1R/TLR signaling in the development of atherosclerosis plaque have triggered intense interest in the molecular mechanisms by which innate immune signaling modulates the onset and development of atherosclerosis. Previous studies have clearly shown the definitive role of proinflammatory cytokine IL-1 in the development of atherosclerosis. Recent studies have provided direct evidence supporting a link between innate immunity and atherogenesis. Although it is still controversial about whether infectious pathogens contribute to cardiovascular diseases, direct genetic evidence indicates the importance of IL-1R/TLR signaling in atherogenesis. In this study, we examined the role of IL-1R-associated kinase 4 (IRAK4) kinase activity in modified low-density lipoprotein (LDL)-mediated signaling using bone marrow-derived macrophage as well as an in vivo model of atherosclerosis. First, we found that the IRAK4 kinase activity was required for modified LDL-induced NF-κB activation and expression of a subset of proinflammatory genes but not for the activation of MAPKs in bone marrow-derived macrophage. IRAK4 kinase-inactive knockin (IRAK4KI) mice were bred onto ApoE(-/-) mice to generate IRAK4KI/ApoE(-/-) mice. Importantly, the aortic sinus lesion formation was impaired in IRAK4KI/ApoE(-/-) mice compared with that in ApoE(-/-) mice. Furthermore, proinflammatory cytokine production was reduced in the aortic sinus region of IRAK4KI/ApoE(-/-) mice compared with that in ApoE(-/-) mice. Taken together, our results indicate that the IRAK4 kinase plays an important role in modified LDL-mediated signaling and the development of atherosclerosis, suggesting that pharmacological inhibition of IRAK4 kinase activity might be a feasible approach in the development of antiatherosclerosis drugs.
Comparison of Radioimmuno and Carbon Nanotube Field-Effect Transistor Assays for Measuring Insulin-Like Growth Factor-1 in a Preclinical Model of Human Breast Cancer (2011)

Both IGF-1 radioimmuno and CNT-FET assays gave comparable results. Indeed, the CNT-FET assay was simpler and faster than the radioimmunoassay. Additionally, the low serum sample required by CNT-FETs can be especially advantageous for studies constricted by limited amount of human clinical samples and for mouse studies, since animals often need to be sacrificed to obtain enough serum for biomarker evaluation.
Cocaine Enhances Human Immunodeficiency Virus Replication in a Model of Severe Combined Immunodeficient Mice Implanted with Human Peripheral Blood Leukocytes (2002)

Epidemiologic studies have identified cocaine as a cofactor for development of acquired immunodeficiency syndrome (AIDS). To evaluate this interaction, human peripheral blood leukocytes (PBL) were implanted into severe combined immunodeficient mice and infected with human immunodeficiency virus (HIV) in both the presence and absence of cocaine. Concurrent administration of cocaine resulted in significantly more PBL becoming infected with HIV in vivo (38.85% vs. 18.5%). The number of CD4(+) cells recovered from HIV-infected, cocaine-treated animals was significantly lower than that from mice infected with HIV in the absence of cocaine (6.5 x 10(4) vs. 19 x 10(4)) and was associated with a lower CD4:CD8 ratio and a dramatic increase in virus load. Exposure to cocaine alone did not affect the implantation of PBL, suggesting a specific interaction between cocaine and HIV. This report describes a model for evaluating HIV cofactors and supports cocaine's role in the development and progression of AIDS.
SERUM METAL ION AND ULTRASOUND ASSESSMENT OF ASYMPTOMATIC METAL-ON-METAL HIP REPLACEMENT (2012)

Purpose There is a postulated association between increased serum metal ions and pseudotumour formation in patients with metal-on-metal hip replacements. The primary aim of this study was to assess the prevalence of pseudotumour in 31 asymptomatic patients with a large femoral head (LFH) metal-on-metal hip implant. This was compared to the prevalence of pseudotumour in 20 matched asymptomatic patients with a hip resurfacing (HRA) and 24 matched asymptomatic patients with a standard metal-on-polyethylene (MOP) total hip. A secondary objective was to assess possible correlation between increased serum metal ions and pseudotumour formation Method Ultrasound examination of the three groups was performed at a minimum follow up of two years. Serum metal ions were measured in the metal-on-metal LFH and HRA groups at a minimum of two years. Results There were 10 (32%) solid or cystic masses in the LFH group with a mean size of 89.3 (8 to 437) cm3. In the HRA group there were five (25%) masses with a mean size of 41.6 (6 to 119) cm3. In the MOP group there was one cystic mass measuring 9.8 cm3. Median serum cobalt and chromium ion levels in the LFH group were 4.50 gL (interquartile range, 2.38 to 7.47) and 2.82 gL (interquartile range, 1.48 to 3.18) compared to 0.83 gL (interquartile range, 0.65 to 1.12) and 1.08 gL (interquartile range, 0.78 to 1.31) in the HRA group. Conclusion This study demonstrates a significantly higher prevalence of pseudotumours in patients with large head metal-on-metal total hips. The higher levels of metal ions in this group suggest that elevated metal ions may lead to pseudotumour formation.
Cancer immunotherapy: are we there yet? (2013)

The immune system is the built-in host defense mechanism against infectious agents as well as cancer. Protective immunity against cancer was convincingly demonstrated in the 1940s with syngeneic animal models (JNCI 18:769-778, 1976; Cancer Immun 1:6, 2001). Since then, the last century's dream has been to effectively prevent and cure cancers by immunological means. This dream has slowly but surely become a reality (Nature 480:480-489, 2011). The successful examples of immunoprophylaxis and therapy against cancers include: (i) targeted therapy using monoclonal antibodies (Nat Rev Cancer 12:278-287, 2012); (ii) allogeneic hematopoietic stem cell transplantion to elicit graft-versus-cancer effect against a variety of hematopoietic malignancies (Blood 112:4371-4383, 2008); (iii) vaccination for preventing cancers with clear viral etiology such as hepatocellular carcinoma and cervical cancer (Cancer J Clin 57:7-28, 2007; NEJM 336:1855-1859, 1997); (iv) T cell checkpoint blockade against inhibitory pathways including targeting CTLA-4 and PD-1 inhibitory molecules for the treatment of melanoma and other solid tumors (NEJM 363:711-723, 2010; NEJM 366:2443-2454, 2012; NEJM 369:122-133, 2013; NEJM 366:2455-2465, 2012); (v) antigen-pulsed autologous dendritic cell vaccination against prostate cancer (NEJM 363:411-422, 2010); and (vi) the transfer of T cells including those genetically engineered with chimeric antigen receptors allowing targeting of B cell neoplasms (NEJM 365:725-733, 2011; NEJM 368:1509-1518, 2013; Blood 118:4817-4828, 2013; Sci Transl Med 5:177ra138, 2013).This article provides an overview on the exciting and expanding immunological arsenals against cancer, and discusses critical remaining unanswered questions of cancer immunology. The inherent specificity and memory of the adaptive immune response towards cancer will undoubtedly propel cancer immunotherapy to the forefront of cancer treatment in the immediate near future. Study of the fundamental mechanisms of the immune evasion of cancer shall also advance the field of immunology towards the development of effective immunotherapeutics against a wide spectrum of human diseases.
SEPARATION OF P‐ AND S‐WAVES* (1985)

A bstract In combined P‐ and SV‐observations with vertical and in‐line horizontal geophones, recognition and separation of the individual P‐ and S‐arrivals may form a considerable problem. Due to the geophone receiving characteristics, P‐ and S‐waves are observed on both horizontal and vertical geophones. A new method of separating P‐ and S‐waves is presented that inverts the geophone records for the receiving characteristics, thereby separating the two wavetypes. The filter coefficients are determined from the near‐surface P‐ and S‐wave velocity and from the geometry of the geophone groups. The P/S‐separation filter was tested on synthetic data with good results. Even PS‐ and SP‐converted reflections, which are completely coinciding for horizontal reflectors, could be well separated. The filter appears to be stable and to have low sensitivity to noise in the data or to errors in the near‐surface P‐ and S‐wave velocity. The filter is superior to other separation methods, which were applied to the same dataset for comparison. This method can also be applied to VSP data.
Histologic Comparison of Breast Implant Shells with Smooth, Foam, and Pillar Microstructuring in a Rat Model from 1 Day to 6 Months (1995)

The purpose of this study was to determine the soft-tissue response to silicone breast implants with different surface morphologies and to correlate implant microtexturing with capsular formation. Using a rat model, we inserted breast implants having three types of shells: micropillared, silicone foam, and smooth silicone (control). We used 96 adult male Sprague-Dawley rats weighing between 250 and 300 gm. Thirty-two rats were assigned to each of the three shell groups. Within each shell group, 4 rats were implanted for 24 hours, 4 for 4 weeks, 4 for 8 weeks, 4 for 12 weeks, 4 for 16 weeks, 4 for 20 weeks, and 4 for 24 weeks. The rats were sacrificed at the end of each time interval, and periprosthetic tissue was obtained for histologic analysis. Our results show a stable soft-tissue response with some macrophages and fibroblasts for the smooth silicone shell group; capsule thicknesses were 10 to 12 cells with interwoven collagen. The silicone foam prolonged the active cellular response with regard to macrophages, fibroblasts, and multinucleated giant cells, along with random collagen deposition and alternating thin and thick capsular areas. The micropillar group had a more stable cellular response, with macrophages and fibroblasts, along with disruption of the long-range orientation of collagen fibers.
Erythrocyte glucose-6-phosphate dehydrogenase and pyruvate kinase activities in hemoglobin H disease. (1992)

Erythrocyte glucose-6-phosphate dehydrogenase (G6PD) and pyruvate kinase (PK) activities were studied in hemoglobin H (HbH) patients by spectrophotometric method, cytochemical method and the methemoglobin reduction (MR) test for the detection of heterozygous G6PD deficiency. G6PD deficiency was found in 7 of 64 cases (10.9%), including 3 cases of genotype alpha 1/alpha 2 and 4 cases of genotype alpha 1/CS. None of the HbH patients was found to be PK-deficient. Spectrophotometrically determined G6PD and PK activities were significantly higher in HbH patients than in normals (p less than 0.001), whereas the MR test yielded a significantly lower percentage of residual methemoglobin in HbH patients than in normals (p less than 0.05). All three methods were efficient in the detection of hemizygous G6PD deficiency in HbH patients, but not in G6PD-deficient females.
A Sensitive Method for Determining the Phosphorylation Status of Natriuretic Peptide Receptors:  cGK-Iα Does Not Regulate NPR-A (2006)

Natriuretic peptide receptor A (NPR-A) and natriuretic peptide receptor B (NPR-B) are transmembrane guanylyl cyclases that catalyze the synthesis of cGMP in response to natriuretic peptides. Phosphorylation and dephosphorylation regulate these receptors and have been traditionally studied by (32)PO(4) labeling of transfected cells. However, this approach cannot be used to determine the phosphorylation state of receptors isolated from unlabeled sources. Here, we use Pro-Q Diamond and SYPRO Ruby dyes to quantify the phosphorylation status and protein levels, respectively, of natriuretic peptide receptors from tissues and cells. Strong Pro-Q Diamond signals for NPR-A and NPR-B were obtained when receptors were isolated from lung tissue, liver tissue and overexpressing cells. The level of NPR-A Pro-Q staining was also high in kidney but was much lower in heart tissue. In contrast, the SYPRO Ruby protein signal was weaker and more variable. In a direct comparison, Pro-Q Diamond staining was as sensitive as but more specific than the (32)PO(4) labeling method. The two approaches were highly correlated (R(2) = 0.98). We exploited these techniques to measure the effect of cGMP-dependent protein kinase Ialpha on the phosphate content and guanylyl cyclase activity of NPR-A. Neither value was significantly affected in cells overexpressing cGK-Ialpha or in tissues from mice lacking cGK-I. We conclude that cGK-I does not regulate the cyclase activity or phosphorylation state of NPR-A. Furthermore, we find that Pro-Q Diamond staining is a sensitive method for measuring the phosphate levels of natriuretic peptide receptors, but protein levels are best detected by Western blot analysis, not SYPRO Ruby staining.
Evaluation of a screener to assess diet quality in the Netherlands (2015)

Generally, there is a need for short questionnaires to estimate diet quality in the Netherlands. We developed a thirty-four-item FFQ--the Dutch Healthy Diet FFQ (DHD-FFQ)--to estimate adherence to the most recent Dutch guidelines for a healthy diet of 2006 using the DHD-index. The objectives of the present study were to evaluate the DHD-index derived from the DHD-FFQ by comparing it with the index based on a reference method and to examine associations with participant characteristics, nutrient intakes and levels of cardiometabolic risk factors. Data of 1235 Dutch men and women, aged between 20 and 70 years, participating in the Nutrition Questionnaires plus study were used. The DHD-index was calculated from the DHD-FFQ and from a reference method consisting of a 180-item FFQ combined with a 24-h urinary Na excretion value. Ranking was studied using Spearman's correlations, and absolute agreement was studied using a Bland-Altman plot. Nutrient intakes derived from the 180-item FFQ were studied according to quintiles of the DHD-index using DHD-FFQ data. The correlation between the DHD-index derived from the DHD-FFQ and the reference method was 0·56 (95% CI 0·52, 0·60). The Bland-Altman plot showed a small mean overestimation of the DHD-index derived from the DHD-FFQ compared with the reference method. The DHD-index score was in the favourable direction associated with most macronutrient and micronutrient intakes when adjusted for energy intake. No associations between the DHD-index score and cardiometabolic risk factors were observed. In conclusion, the DHD-index derived from the DHD-FFQ was considered acceptable in ranking but relatively poor in individual assessment of diet quality.

Importance of newly generated neurons in the adult olfactory bulb for odor discrimination (2000)

In adult rodents, neurons are continually generated in the subventricular zone of the forebrain, from where they migrate tangentially toward the olfactory bulb, the only known target for these neuronal precursors. Within the main olfactory bulb, they ascend radially into the granule and periglomerular cell layers, where they differentiate mainly into local interneurons. The functional consequences of this permanent generation and integration of new neurons into existing circuits are unknown. To address this question, we used neural cell adhesion molecule-deficient mice that have documented deficits in the migration of olfactory-bulb neuron precursors, leading to about 40% size reduction of this structure. Our anatomical study reveals that this reduction is restricted to the granule cell layer, a structure that contains exclusively gamma-aminobutyric acid (GABA)ergic interneurons. Furthermore, mutant mice were subjected to experiments designed to examine the behavioral consequences of such anatomical alteration. We found that the specific reduction in the newly generated interneuron population resulted in an impairment of discrimination between odors. In contrast, both the detection thresholds for odors and short-term olfactory memory were unaltered, demonstrating that a critical number of bulbar granule cells is crucial only for odor discrimination but not for general olfactory functions.
Identification of Genomic Safe Harbors in the Anhydrobiotic Cell Line, Pv11. (2022)

Genomic safe harbors (GSHs) provide ideal integration sites for generating transgenic organisms and cells and can be of great benefit in advancing the basic and applied biology of a particular species. Here we report the identification of GSHs in a dry-preservable insect cell line, Pv11, which derives from the sleeping chironomid, <em>Polypedilum vanderplanki</em>, and similar to the larvae of its progenitor species exhibits extreme desiccation tolerance. To identify GSHs, we carried out genome analysis of transgenic cell lines established by random integration of exogenous genes and found four candidate loci. Targeted knock-in was performed into these sites and the phenotypes of the resulting transgenic cell lines were examined. Precise integration was achieved for three candidate GSHs, and in all three cases integration did not alter the anhydrobiotic ability or the proliferation rate of the cell lines. We therefore suggest these genomic loci represent GSHs in Pv11 cells. Indeed, we successfully constructed a knock-in system and introduced an expression unit into one of these GSHs. We therefore identified several GSHs in Pv11 cells and developed a new technique for producing transgenic Pv11 cells without affecting the phenotype.
Detection of Off-screen Sound Based on Loss Function of Self-supervised Audio-visual Spatialization (2021)

This paper presents a method to detect off-screen sounds based on a loss function of self-supervised audio-visual spatialization. Audio source separation is a long-standing problem, and audio-visual source separation has recently attracted attention in the field of acoustic signal processing, image processing and machine learning. Although visual information in a video has important cues for audio source separation, it does not have information about sounds whose sources are not found in the video. The proposed method detects such off-screen sounds by focusing on correspondences between sounds and their sources in the video. For finding the correspondences, we use audio-visual spatialization, which converts mono audio into spatial audio with visual guidance. Experimental results show that the proposed method can achieve high accuracy in the task of off-screen sound detection.
Lifeguard/neuronal membrane protein 35 regulates Fas ligand‐mediated apoptosis in neurons via microdomain recruitment (2007)

Fas ligand (FasL)-receptor system plays an essential role in regulating cell death in the developing nervous system, and it has been implicated in neurodegenerative and inflammatory responses in the CNS. Lifeguard (LFG) is a protein highly expressed in the hippocampus and the cerebellum, and it shows a particularly interesting regulation by being up-regulated during postnatal development and in the adult. We show that over-expression of LFG protected cortical neurons from FasL-induced apoptosis and decreased caspase-activation. Reduction of endogenous LFG expression by small interfering RNA sensitized cerebellar granular neurons to FasL-induced cell death and caspase-8 activation, and also increased sensitivity of cortical neurons. In differentiated cerebellar granular neurons, protection from FasL-induced cell death could be attributed exclusively to LFG and appears to be independent of FLICE inhibitor protein. Thus, LFG is an endogenous inhibitor of FasL-mediated neuronal death and it mediates the FasL resistance of CNS differentiated neurons. Finally, we also demonstrate that LFG is detected in lipid rafts microdomains, where it may interact with Fas receptor and regulate FasL-activated signaling pathways.
Genetic and epigenetic changes in the common 1p36 deletion in neuroblastoma tumours (2007)

Chromosome 1p is frequently deleted in neuroblastoma (NB) tumours. The commonly deleted region has been narrowed down by loss of heterozygosity studies undertaken by different groups. Based on earlier mapping data, we have focused on a region on 1p36 (chr1: 7 765 595-11 019 814) and performed an analysis of 30 genes by exploring features such as epigenetic regulation, that is DNA methylation and histone deacetylation, mutations at the DNA level and mRNA expression. Treatment of NB cell lines with the histone deacetylase inhibitor trichostatin A led to increased gene transcription of four of the 30 genes, ERRFI1 (MIG-6), PIK3CD, RBP7 (CRBPIV) and CASZ1, indicating that these genes could be affected by epigenetic downregulation in NBs. Two patients with nonsynonymous mutations in the PIK3CD gene were detected. One patient harboured three variations in the same exon, and p.R188W. The other patient had the variation p.M655I. In addition, synonymous variations and one variation in an intronic sequence were also found. The mRNA expression of this gene is downregulated in unfavourable, compared to favourable, NBs. One nonsynonymous mutation was also identified in the ERRFI1 gene, p.N343S, and one synonymous. None of the variations above were found in healthy control individuals. In conclusion, of the 30 genes analysed, the PIK3CD gene stands out as one of the most interesting for further studies of NB development and progression.
Application of new pyrethroid, fluvalinate to wood preservatives. (1988)

新しいピレスロイド系化合物であるフルバリネートについて,種々の室内試験及び野外試験を行い,しろあり防除薬剤としての可能性を検討した。フルバリネートは,パーメスリン及びフェンバレレートと同等,それ以上の防蟻効力を示し,共力剤を配合することによりフルバリネートの濃度を低下できる可能性がある。また,フルバリネートは,光安定性及び土壌中での安定性が比較的高かった。フルバリネートを有効成分とする木部処理用油剤は,高い防蟻および防腐性能を示し,土壌処理用乳剤についても低濃度で十分な効力を発現した。フルバリネートは,毒性が低くまた環境中での移行性がほとんどないことから,作業者等に対する安全性や環境保全の点で優れており,現行の有機リン系しろあり防除薬剤に替わるものとして期待される。
10 GHz PLL using active shunt-peaked MCML gates and improved frequency acquisition XOR phase detector in 0.18 /spl mu/m CMOS (2004)

When designing circuits operating at high frequencies, some design techniques are quite useful. Some recommended techniques include using MCML gate structures, simple structures, inductive loads and symmetric gates. By considering all these elements in the design process, a PLL working at speeds above 10 GHz has been realized in standard 0.18/spl mu/m CMOS process. In simulations, the PLL locked onto a reference clock with a period of 94 ps in little over 200 ns. This circuit was implemented and sent to TSMC for fabrication.
