Crystal Growth and Photoelectrochemical Characterization of Cd4BSe6 (B = Si or Ge) (1990)

Abstract Single crystals of Cd 4 BSe 6 (B = Si, Ge) (ARGYRODITES) were grown by CVT method using a three zone furnace. As‐grown crystals were of n‐type and they have been characterized by photoelectrochemical (PEC) measurements in aqueous electrolytes. The current‐potential curves, Mott‐Schottky plots and action spectra were examined. From the analysis of spectral response measurements the band gaps (indirect) for Cd 4 SiSe 6 and Cd 4 GeSe 6 were found to be 1.68 and 1.5 eV, respectively. The opencircuit photopotentials for these semiconductor electrodes were as high as 1.1 V vs. SCE in some of the electrolytes used.

Repellency of Essential Oil of Piper aduncum Against Aedes albopictus in the Laboratory (2009)

The repellent activity of Piper aduncum essential oil against Aedes albopictus was investigated under laboratory conditions with human volunteers. The lowest median effective dose (ED50) value was 1.5 microg/cm2 at 60 sec of exposure when compared to 90 sec (2.1 microg/cm2) and 120 sec (1.8 microg/cm2) of exposure. At 0.4 g, the essential oil gave a high protection (95.2%) against Ae. albopictus bites or landing at 2 h postapplication. The percentage of protection was reduced to 83.3% after 4 h, 64.5% after 6 h, and 51.6% after 8 h postapplication. As a comparison, treatment with 10% deet gave 100% protection against mosquito biting/landing for 4 h postapplication. There was no significant difference in percentage protection reduction between the plant extract and the commercial product deet, respectively (P = 0.739). The essential oil, which was not as good as deet, still gave moderate protection against Ae. albopictus biting even until 4 h postapplication. In conclusion, the P. aduncum essential oil has the potential to be used as a repellent against the dengue/dengue hemorrhagic fever vector, Ae. albopictus.
Magnetic and magnetostrictive properties of cube textured nickel for magnetostrictive transducer applications (1973)

Magnetic and magnetostrictive properties of {100} <100> textured, polycrystalline nickel sheet have been measured in the <100> direction and compared with a randomly oriented nickel sheet. The {100} <100> textured nickel produced a 51 percent increase in the available magnetostrictive strain energy along with a 21 percent decrease in sound velocity. These improved characteristics when combined with an equivalent electromechanical coupling coefficient and a nearly linear response of magnetostrictive strain to the applied magnetic field, make "cube" textured nickel sheet an attractive new material for many transducer applications.
Association of M3 muscarinic receptors and Kir6.1 with human detrusor caveolae (2011)

Caveolae are 50–100 nm large membrane invaginations that represent a plasmalemmal sub‐compartment of relevance for cellular signaling. We aimed to assess whether the muscarinic receptor M3 and the K‐ATP channel Kir6.1 are associated with human detrusor caveolae and to probe the functional relevance of this organization. Muscle strips were dissected from human detrusors and used in ultrastructural, biochemical and mechanical studies. Caveolae were ablated by cholesterol desorption with methyl‐β‐cyclodextrin. The subcellular distribution of M3 muscarinic receptors and Kir6.1 was examined using sucrose density fractionation and immunoelectron microscopy. Desorption of cholesterol right‐shifted the concentration‐response curve for the muscarinic receptor agonist carbachol. Using a K‐ATP channel inhibitor (glibenclamide) and activator (levcromakalim), we were able to inhibit and mimic this effect, respectively. Sucrose density fractionation revealed co‐fractionation of detrusor M3 receptors and Kir6.1, in partial overlap with caveolin‐1. Immunoelectron microscopy showed M3 in caveolae and in sub‐plasmalemmal caveolae‐like structures. Thus, M3 receptors are enriched with Kir6.1 in caveolae, and this organization underpins cholinergic detrusor activation in man.

Excited State Dynamics of Two New Ru(II) Cyclometallated Dyes: Relation to Cells for Solar Energy Conversion and Comparison to Conventional Systems (2012)

The preparation, characterization, and photophysical properties of a series of ruthenium(II) complexes possessing the cyclometallating deprotonated 2-phenyl pyridine ligand, phpy–, together with dppn (benzo[i]dipyrido[3,2-a:2′,3′-c]phenazine), a ligand with an extended π-system, are reported. Related complexes have been used as efficient dyes in dye-sensitized solar cells (DSSCs), and the Ru→dppn metal-to-ligand charge transfer (MLCT) absorption of the new complexes [Ru(phpy)(bpy)(dppn)]+ (4) and [Ru(phpy)(dppn)2]+ (5) is red-shifted relative to the Ru→bpy MLCT peak in [Ru(phpy)(bpy)2]+ (3). These new compounds are compared to conventional complexes where phpy– is replaced by 2,2′-bipyridine (bpy), including [Ru(bpy)3]2+, [Ru(bpy)2(dppn)]2+ (1), and [Ru(bpy)(dppn)2]2+ (2). Unlike 1 and 2, with long-lived dppn-centered 3ππ* excited states (τ ∼ 20 μs), the corresponding cyclometallated complexes 4 and 5 exhibit weakly emissive Ru→dppn 3MLCT states with transient absorption lifetimes of 25 and 45 ps, respectively, which are significantly shorter than that of 3, ∼9 ns. Although it is desirable to shift the absorption of ruthenium dyes used in DSSCs to lower energies, it is evident from this work, that for cyclometallated phpy– complexes, lowering the energy of the 3MLCT state below that of 3 results in significant shortening of the excited state lifetime. The fast excited state decay, together with the lower energy of the 1MLCT state, may result in lower charge injection efficiencies from these types of complexes.
Individual Radio Pulses from NP 0531 (1971)

Observations with a swept frequency machine show that the shapes of individual pulses from NP 0531 are truncated exponentials with widths proportional to λ ~4 , consistent with the broadening arising from scattering in the interstellar medium. A histogram of pulse intensity reveals two different populations. The very strong pulses are associated only with the main pulse and interpulse.
Applying the Expansion MicroscopyMethod in Neurobiology (2021)

Many biological studies require the analysis of ultrastructural changes at the level of cell organelles and macromolecules. Since the resolution of modern confocal microscope is limited by the diffraction limit (200–300 nm), it is impossible to study such small objects using standard fluorescence microscopy. Ultra-high resolution microscopy methods require expensive equipment and are technically difficult in use, which in turn limits their widespread practical application. However, recently appeared methods make it possible to increase the resolution of microscopy not by improving the image registration system, but by physically isotropic expansion of a biological sample using a controlled chemical process. Due to this method, called expansion or expansive microscopy (ExM), it became possible to obtain three-dimensional images of samples with a resolution sufficient to study individual cell organelles using a conventional confocal microscope. This review covers the history of this method, its basic principles and examples of use in various fields of biology and medicine, as well as reflects future directions for improving this technology. The article discusses the methodological features of the ExM application in a study of brain tissue samples using the algorithm that allows adaptation of the standard protocol to the goals and objectives of a particular study.
Cytomegalovirus infection associated with smaller dentate gyrus in men with severe mental illness (2021)

Cytomegalovirus (CMV) infection is usually inapparent in healthy adults but persists for life. Neural progenitor/stem cells are main CMV targets, and dentate gyrus (DG) a major neurogenic niche. Smaller DG volume has been repeatedly reported in severe mental illness (SMI). Considering the suggested immune system, blood-brain barrier and DG disturbances in SMI, we hypothesized that CMV exposure is associated with smaller DG volume in patients, but not healthy controls (HC). Due to the differential male and female immune response to CMV, we hypothesized sex-dependent associations. 381 adult patients with SMI (schizophrenia spectrum or bipolar spectrum disorders) and 396 HC were included. MRI scans were obtained with 1.5T Siemens MAGNETOM Sonata scanner or 3T General Electric Signa HDxt scanner, and processed with FreeSurfer v6.0. CMV immunoglobulin G antibody concentrations were measured by solid phase immunoassay. We investigated main and interaction effects of CMV status (antibody positivity/CMV + vs. negativity/CMV-) and sex on DG in patients and HC. Among patients, there was a significant CMV-by-sex interaction on DG (p = 0.009); CMV + male patients had significantly smaller DG volume than CMV- male patients (p = 0.001, 39 mm<sup>3</sup> volume difference) whereas no CMV-DG association was found in female patients. Post-hoc analysis among male patients showed that the CMV-DG association was present in both hemispheres and in both patients with schizophrenia spectrum and bipolar spectrum disorders, and further, that higher CMV antibody titers were associated with smaller DG. No CMV-DG association was found in HC. The results indicate a DG vulnerability to CMV infection in men with SMI.

Assessment of Lung Deposition and Breathing Rate of Underground Miners in Tadjikistan (1995)

Deposited gamma ray activity in miners' lungs and airborne concentrations of 222Rn decay products were measured in a metal mine in Tadjikistan. Measurements for about 100 miners were performed, using filtered air samples to estimate their decay product exposures and a field gamma ray system to determine corresponding chest activities. These two quantities yielded the deposited lung activity per unit exposure, which is proportional to the product of the average minute volume and the fractional lung deposition, called here the 'filtration ability of lungs' (FAL). The group average FALs were found to be, for drillers, assistant drillers, and inspection personnel, respectively, 0.0079, 0.0067, and 0.0052 m3.min-1, with approximately 20% standard error. Independent measurements were also made, for a group of mine workers engaged in light work, not only of FAL, but also of breathing rate (minute volume), permitting estimation of the lung deposition fraction, found to average 0.34±0.03. Finally, this value was used together with the group FALs noted to yield upper-bound estimates of the average minute volumes for these job categories, respectively, 0.023±0.004, 0.020±0.004, and 0.015±0.003 m3.min-1.
Virulence Factor NSs of Rift Valley Fever Virus Recruits the F-Box Protein FBXO3 To Degrade Subunit p62 of General Transcription Factor TFIIH (2014)

Rift Valley fever virus is a serious emerging pathogen of animals and humans. Its main virulence factor, NSs, enables unhindered virus replication by suppressing the antiviral innate immune system. We identified the E3 ubiquitin ligase FBXO3 as a novel host cell interactor of NSs. NSs recruits FBXO3 to destroy the general host cell transcription factor TFIIH-p62, resulting in suppression of the transcriptional upregulation of innate immunity.
Quantitative Radionuclide Scanning of the Temporomandibular Joint (1987)

Patients suspected of having internal derangement of a temporomandibular joint were evaluated clinically, radiologically, and with a quantitative technique using a bone-seeking radionuclide, technetium-MDP. Comparison of computer-generated ratios of activity demonstrated increased tracer localization within the temporomandibular joints of the patient population, as compared with a control population. The results reflect increased rates of degeneration and repair of the osseous structures in patients with internal derangement. Comparisons of pre- and postorthotic bone scans illustrate a marked decrease in the uptake of the radionuclide. This paper describes the technique and future applications.

Embracing Interference in Ad Hoc Networks Using Joint Routing and Scheduling with Multiple Packet Reception (2008)

We present an approach that takes advantage of multi-packet reception (MPR) to reduce the negative effects of multiple access interference and therefore increase the capacity of an ad hoc network. We analyze the performance upper bound of joint routing and scheduling for ad hoc networks that embrace interference by using MPR. We formulate the optimization problem under a deterministic model and seek to maximize the aggregate network throughput subject to minimum rate requirements. We then propose a polynomial-time heuristic algorithm aimed at approximating the optimal solution to the joint routing and channel access problem under MPR. We show the effectiveness of our heuristic algorithm by comparing its performance with the upper bound.
Effect of Geranylgeraniol and Green Tea Polyphenols on High-fat-diet-induced Bone Deterioration in Male B6 Mice (P06-025-19) (2019)

To investigate the combined effects of geranylgeraniol (GG, a 20-carbon isoprenoid found in fruits, vegetables, and grains) and green tea polyphenols (GTP, extracted from green tea) on high-fat-diet (HFD) induced bone deterioration in obese male mice. Our previous studies demonstrated that GG or GTP, when supplemented separately, was beneficial to the bone health of obese animals. Therefore, we hypothesized that GG combined with GTP would improve bone structure of obese mice fed a HFD. Forty-eight male C57BL/6 J mice were assigned to 4 groups (n = 12/group) in a 2 (no GG vs. GG) × 2 (no GTP vs. GTP) factorial design: HFD, HFD + GG (400 mg GG/kg diet), HFD + GTP [0.5% (w/v) in drinking water], and HFD + GG + GTP. Animals were fed the respective diet ad libitum for 14 weeks. GTP supplementation, not GG, resulted in lower final body weight and greater fasting serum insulin concentrations. Supplementation of GG or GTP (separate, but not together) lowered blood glucose concentrations at 120 min. A decreased area under the curve of glucose tolerance tests and insulin tolerance test in the HFD + GG + GTP group was observed suggesting improved glucose clearance and insulin sensitivity, but no interaction was found between GG and GTP. Neither GG nor GTP affected serum concentrations of insulin or procollagen type I intact N-terminal (a bone formation marker). There was an interaction effect for serum concentrations of collagen type 1 cross-linked C-telopeptide (CTX, a bone resorption marker), resulting in HFD + GG + GTP being the lowest. Neither GG nor GTP supplementation affected the total area, bone area, and cortical thickness at the femur midshaft or the bone volume/total volume at the lumbar vertebrae. GG supplementation increased trabecular number and decreased trabecular separation at the lumbar vertebrae. GTP supplementation increased trabecular thickness at lumbar vertebrae. HFD + GG produced the greatest connectivity density and the lowest structure model index. This study suggests a beneficial role of supplementing GG with GTP in bone health of obese animals. The study was supported by American River Nutrition to CLS and USDA ARS Project no. 3062-51,000-053-00D.
A Study on System Stress Analysis of High Temperature Plant Piping with Expansion Joints and Load Hangers (2014)

고온에서 운전되는 플랜트에서는 열변형에 의한 배관 사고를 예방하고 배관계통의 우선 검사관리 부위의 선정을 위해 배관 시스템하중 해석을 수행하는 경우가 많다. 본 연구에서는 국내 한 공정플랜트에서 설계변경에 따라 반응기와 반응기 사이에 추가 설치된 연결배관을 대상으로 배관 시스템응력해석을 수행하였다. 특히 배관에 일반적으로 설치되는 하중행거(hanger) 이외에 열팽창을 흡수하는 신축이음(expansion joint)이 함께 설치된 경우의 배관 특성을 연구하였다. 이를 위해 배관 응력을 형성하는 구조적 요인의 영향을 평가하기 위해 배관계에 포함된 행거와 신축이음이 비정상적으로 작동되는 경우도 가정하여 해석하였다. 추가적인 인입라인이 있는 경우도 해석을 수행하였다. 정상 운전 시 배관계의 시스템 응력 결과와 비정상적인 운전 경우의 해석결과를 비교하여 각각 배관요소의 역할을 연구하였다. In the plants operated under high temperature condition, piping system load analysis is often performed to prevent accidents caused by thermal deformation and also to locate inspection prioritity points of the piping system. In this study, piping system stress analysis was performed for a pipe system between the reactors in a process plant. The piping system includes typically installed hangers and expansion joints. In order to evaluate the effects of structural components such as hangers and expansion joints, the case for the expansion joint or the hanger under abnormal operation is considered. By comparison anlaysis results of piping system during normal operation and abnormal operation, the role of each pipe components are studied.
La vision située : un concept pour faciliter l’autonomie des systèmes (2007)

This paper is about vision to make systems more autonomous. We parallel two aspects of the current evolution of&#13;\nSystem-Perception: more ambitious yet coherent tasks tightly rely on more abstract description and control. As vision is&#13;\nlikely to be a major and complex sensory modality for machines as it is for most animals, we concentrate our development&#13;\non it. In the first part we show how thinking to systems helped to better pose vision problems and solve them in a useful&#13;\nmanner. That is the “active vision” trend that we explain and illustrate. Along the same line, the necessity for anticipation&#13;\nshows further, leading to a first definition of “situated vision”. The second part deals with how to design systems able to&#13;\nachieve such vision. We show from a few examples how architectural descriptions evolve and better fit important&#13;\nfeatures to grasp – a model – in view of more efficient control towards intelligence. Inner communication flows are&#13;\nbetter be controlled than local tasks that should be assumed completed efficiently enough in all cases. We conclude&#13;\nwith a plausible sketch of a system to be experimented on in situations that require some autonomy.
Deficient Vasoactive Intestinal Peptide Innervation in the Sweat Glands of Cystic Fibrosis Patients (1985)

The innervation of acini and ducts of eccrine sweat glands by immunoreactive, vasoactive intestinal peptide-containing nerve fibers was sharply reduced in seven patients with cystic fibrosis compared to eight normal subjects. The decrease in innervation by this neuropeptide, which has been shown to promote blood flow and the movement of water and chloride across epithelial surfaces in other systems, may be a basic mechanism for the decreased water content and relative impermeability of the epithelium to chloride and other ions that characterize cystic fibrosis.
Smoothing the Transition to Postsecondary Education: The Impact of the Early College Model (2016)

Developed in response to concerns that too few students were enrolling and succeeding in postsecondary education, early college high schools are small schools that blur the line between high school and college. This article presents results from a longitudinal experimental study comparing outcomes for students accepted to an early college through a lottery process with outcomes for students who were not accepted through the lottery and enrolled in high school elsewhere. Results show that treatment students attained significantly more college credits while in high school, and graduated from high school, enrolled in postsecondary education, and received postsecondary credentials at higher rates. Results for subgroups are included.
Staphylococcus aureus alpha-toxin inhibits CD8 + T cell-mediated killing of cancer cells in cutaneous T-cell lymphoma (2020)

<i>Staphylococcus aureus</i> and its toxins have been linked to disease progression and mortality in advanced stages of cutaneous T-cell lymphoma (CTCL). CD8<sup>+</sup> T cells play a crucial role in anti-cancer responses and high CD8<sup>+</sup> T cell numbers in tumor lesions are associated with a favorable prognosis in CTCL. Here, we show that CD8<sup>+</sup> T cells from both healthy donors and Sézary syndrome patients are highly susceptible to cell death induced by Staphylococcal alpha-toxin, whereas malignant T cells are not. Importantly, alpha-toxin almost completely blocks cytotoxic killing of CTCL tumor cells by peptide-specific CD8<sup>+</sup> T cells, leading to their escape from induced cell death and continued proliferation. These findings suggest that alpha-toxin may favor the persistence of malignant CTCL cells <i>in vivo</i> by inhibiting CD8<sup>+</sup> T cell cytotoxicity. Thus, we propose a novel mechanism by which colonization with <i>Staphylococcus aureus</i> may contribute to cancer immune evasion and disease progression in CTCL.
A further whole arm 1;19 translocation with alpha-satellite DNA breakage. (1997)

A balanced whole arm translocation (1;19)(p10;q10) was found in a woman with normal phenotype ascertained through a fragile X survey. Chromosome painting with the specific libraries confirmed the cytogenetic diagnosis. Fluorescence in situ hybridization with a chromosome-1 alpha-satellite probe revealed that the breakpoint in chromosome 1 split the alpha-satellite sequences into two blocks. The review of constitutional whole arm translocations revealed a greater participation of some chromosomes with recurrence of translocations t(1;19)(1p19q;1q19p), t(18;20)(18p20q;18q20p) and t(X;17)(Xp17q;Xq17p). The alpha-satellite breakage documented in some derivatives of the recurrent translocations may be related to highly homologous subsets in the involved chromosome pairs, which belong to alpha-satellite subfamilies 1, 2 and 3 respectively. Probably this leads to abnormal chromosome pairing and thus to whole arm translocations.
