The use of haloperidol as a long-acting neuroleptic in game capture operations. (1981)

Haloperidol (R1625, Serenace) a potent, long-acting butyrophenone neuroleptic, was shown to be very effective in game capture operations for the neuroleptization of several species of African wild herbivores, especially the medium and small antelopes. With a rapid onset of action following intravenous injection and a duration of action of 10-12 h in the majority of cases, haloperidol produced profound pyschomotor effects and remarkable tractability in red hartebeest, blesbok, springbok, duiker, steenbok and dik dik. Haloperidol suppressed the alarm reaction and facilitated the large-scale handling and translocation of captured animals. It also produced favourable sedation in Hartmann's zebra, Burchell's zebra, tsessebe and Black-faced impala. Extrapyramidal effects were observed in some species.
Identification of amyloid β-peptide responsive genes by cDNA microarray technology: Involvement of RTP801 in amyloid β-peptide toxicity (2003)

Amyloid beta-peptide (Abeta), a causative molecule in the pathogenesis of Alzheimer's disease and the main component of senile plaques, is known to be neurotoxic in vitro and in vivo. The mechanisms involved in this Ab-mediated neurotoxicity are not fully understood, although there is evidence to suggest the involvement of oxidative stress, alterations in calcium homeostasis, and/or of CDK activators. Many studies have suggested that Ab may exert its toxic effect via the activation of transcription factors. Therefore, we investigated Ab- responsive genes in human neuroblastoma CHP134 cells using 3.1K human DNA microarrays. Among the several genes overexpressed or repressed by Ab, RTP801, Hi95/sestrin 2, and stanniocalcin 2 were confirmed to be Ab-mediated overexpression in the cells by semiquantitative RT-PCR. Transient expression of the sense RTP801 gene in CHP134 cells increased sensitivity to Abeta cytotoxicity and the expression of the antisense RTP801 gene protected the cells from the Abeta toxicity. These results suggest that RTP801 might play important roles in Abeta toxicity and the pathogenesis of Alzheimer's disease.
Servitization of the manufacturing firm (2013)

Purpose: This paper aims to explore practices and technologies successfully servitised manufacturers employ in the delivery of advanced services. Design/methodology/approach: A case study methodology is applied across four manufacturing organisations successful in servitization. Through interviews with personnel across host manufacturers, their partners, and key customers, extensive data are collected about service delivery systems. Analyses identify convergence in their practices and technologies. Findings: Six distinct technologies and practices are revealed: facilities and their location, micro-vertical integration and supplier relationships, information and communication technologies (ICTs), performance measurement and value demonstration, people deployment and their skills, and business processes and customer relationships. These are then combined in an integrative framework that illustrates how operations are configured to successfully deliver advanced services. Research limitations/implications: The analyses are reductive and rationalising. Future studies could identify other technologies and practices. Case study as a method is inherently limited in the extent to which findings can be generalised. Practical implications: Awareness and interest in servitization is growing, yet adoption of a servitization strategy requires particular organisational capabilities on the part of the manufacturer. This study identifies technologies and practices that underpin these capabilities. Originality/value: This paper contributes to the understanding of the servitization process and, in particular, the implications to broader operations of the firm.
Claudin‐16 reduces the aggressive behavior of human breast cancer cells (2008)

Claudin-16 (Paracellin-1) is a transmembrane tight junction (TJ) protein originally described as having a critical role in the re-absorption of magnesium and calcium in the kidney. This study examined expression of Claudin-16 in human breast cells and tissues to identify a possible link between expression and aggressiveness in cells and between Claudin-16 levels and patient prognosis. Insertion of the Claudin-16 gene into MDA-MB-231 human breast cancer cells resulted in cells that were significantly less motile and invasive in behavior, with increased adhesion to matrix. These cells also exhibited significantly increased TJ functionality and "tighter" colony morphology. Moreover, growth rates were reduced in both in vitro and in vivo assays (P < 0.002). Frozen sections from breast cancer primary tumors (matched tumor 124 and background 33) were immuno-stained. RNA was reverse transcribed and analyzed by Q-PCR (standardized using beta-actin, normalized with cytokeratin-19 levels). Levels of expression of Claudin-16 were significantly decreased in node positive tumors compared to negative (P = 0.016). Expression was significantly lower in patients with node positive tumors (P = 0.016) and in those who had died from breast cancer or had general poor prognosis (P < 0.015). Immunohistochemical staining showed decreased expression of Claudin-16 in tumor sections (P < 0.00001). In conclusion, forced expression of Claudin-16 in breast cancer cells resulted in a less aggressive phenotype and reduced in vivo tumor volume. Claudin-16 expression was reduced in human breast cancer, particularly in patients with aggressive tumors and high mortality. This suggests that Claudin-16 plays a role beyond that of an initial metastasis repressor in this cancer type.
Self-aligned (top and bottom) double-gate MOSFET with a 25 nm thick silicon channel (2002)

In this paper, we report a fabrication method that attains the "ideal" double-gate MOSFET device structure. The top and bottom gates are inherently self-aligned to the source/drain. The source/drain is a fanned-out source/drain structure, which provides a low parasitic resistance. Channel silicon thickness is determined by a planar film deposition process with good uniformity control in principle. N-channel double-gate MOSFET's with a 25 nm thick silicon channel were successfully demonstrated.
Radionuclide Demonstration of Ventilatory Abnormalities in Mild Asthma (1984)

The distribution of 5 microns 99mTc aerosol particles deposited in the lungs was compared with that of 81mKr gas in 20 asthmatic subjects (FEV1.0 greater than or equal to 75% predicted) whose asthma was mild or in remission. Sixteen normal non-smokers and 14 'normal' cigarette smokers were studied as control subjects. Radioaerosol lung penetration in the 'normal' smokers was the same as in the normal non-smokers but was reduced in the asthmatic subjects. Radioaerosol penetrated better than 81mKr to the lung apices of normal non-smokers and asthmatic subjects; it penetrated better than 81mKr to the lung bases of the asthmatic subjects. Uneven distribution of aerosol relative to 81mKr related strongly to maximal mid-expiratory flow rate (MMFR) in the asthmatic subjects. Aerosol deposition abnormalities in symptom-free asthmatic subjects may reflect basal airways closure at functional residual capacity and abnormal patterns of lung filling.
A radiation hybrid map of the proximal long arm of human chromosome 11 containing the multiple endocrine neoplasia type 1 (MEN-1) and bcl-1 disease loci. (1991)

We describe a high-resolution radiation hybrid map of the proximal long arm of human chromosome 11 containing the bcl-1 and multiple endocrine neoplasia type 1 (MEN-1) disease gene loci. We used X-ray irradiation and cell fusion to generate a panel of 102 hamster-human somatic cell hybrids containing fragments of human chromosome 11. Sixteen human loci in the 11q12-13 region were mapped by statistical analysis of the cosegregation of markers in these radiation hybrids. The most likely order for these loci is C1NH-OSBP-(CD5/CD20)-PGA-FTH1-COX8-PYGM -SEA-KRN1-(MTC/P11EH/HSTF1/INT2)-GST3- PPP1A. Our localization of the human protooncogene SEA between PYGM and INT2, two markers that flank MEN-1, suggests SEA as a potential candidate for the MEN-1 locus. We map two mitogenic fibroblast growth factor genes, HSTF1 and INT2, close to bcl-1, a mapping that is consistent with previously published data. Our map places the human leukocyte antigen genes CD5 and CD20 far from the bcl-1 locus, indicating that CD5 and CD20 expression is unlikely to be altered by bcl-1 rearrangements. PPP1A, which has been postulated as a MEN-1 candidate tumor suppressor gene, and GST3, a gene transcriptionally active in many human cancers, both map distal to the bcl-1 translocation cluster and the region containing MEN-1, and therefore are unlikely to be directly involved in bcl-1 or MEN-1.
Testis‐specific expression of the β2 tubulin promoter of Aedes aegypti and its application as a genetic sex‐separation marker (2006)

Sex-specific expression of transgenes in pest insects enables novel genetic control strategies, based either on genetic sexing or the spread of transgenes through the germ-line, to be developed and then tested for implementation. We describe the isolation of the beta tubulin genes from the yellow fever mosquito, Aedes aegypti, and the identification of the particular beta2 tubulin gene which has expression confined to the testes. We demonstrate that the beta2 tubulin promoter of Ae. aegypti can direct the expression of a DsRed genetic marker in the testes and show that labelled sperm can be detected in inseminated spermathecae. The applications for this technology in the genetic control of Ae. aegypti are discussed.
Testosterone Therapy in Adult Men with Androgen Deficiency Syndromes: An Endocrine Society Clinical Practice Guideline (2006)

We recommend making a diagnosis of androgen deficiency only in men with consistent symptoms and signs and unequivocally low serum testosterone levels. We suggest the measurement of morning total testosterone level by a reliable assay as the initial diagnostic test. We recommend confirmation of the diagnosis by repeating the measurement of morning total testosterone and in some patients by measurement of free or bioavailable testosterone level, using accurate assays. We recommend testosterone therapy for symptomatic men with androgen deficiency, who have low testosterone levels, to induce and maintain secondary sex characteristics and to improve their sexual function, sense of well-being, muscle mass and strength, and bone mineral density. We recommend against starting testosterone therapy in patients with breast or prostate cancer, a palpable prostate nodule or induration or prostate-specific antigen greater than 3 ng/ml without further urological evaluation, erythrocytosis (hematocrit > 50%), hyperviscosity, untreated obstructive sleep apnea, severe lower urinary tract symptoms with International Prostate Symptom Score (IPSS) greater than 19, or class III or IV heart failure. When testosterone therapy is instituted, we suggest aiming at achieving testosterone levels during treatment in the mid-normal range with any of the approved formulations, chosen on the basis of the patient's preference, consideration of pharmacokinetics, treatment burden, and cost. Men receiving testosterone therapy should be monitored using a standardized plan.
Expression, purification, crystallization and crystallographic characterization of dimeric and monomeric human neutrophil gelatinase associated lipocalin (NGAL) (1998)

Crystals of the monomeric and dimeric forms of human neutrophil gelatinase associated lipocalin have been grown in hanging-drop vapor-diffusion trials using PEG as a precipitating agent with recombinant protein expressed in a baculovirus-based system. Crystals of monomeric NGAL belong to the cubic space group P432 with lattice constants a = b = c = 126.6 A; crystals of dimeric NGAL belong to the tetragonal space group P41212 (or its enantiomorph P43212) with lattice constants a = b = 54.14 and c = 121.56 A. Isomorphous crystals of the NGAL dimer can be grown in the presence of ligand: the tripeptide N-formyl-Met-Leu-Phe.
The structure of cerexin B. Studies on antibiotics from the genus Bacillus. XVII. (1976)

The structure of cerexin B was examined. The constituent fatty acids were elucidated by gas chromatography and mass spectrometry to be β-hydroxy isodecanoic acid, β-hydroxy decanoic acid, β-hydroxy isoundecanoic acid and β-hydroxy anteisoundecanoic acid. The configurations of constituent amino acids were determined as asparagine (2D, 1L), valine (D), phenylalanine (D), allo-threonine (D), tryptophan (D), andallo-isoleucine (D) from their optical activities. Treatment with conc. hydrochloric acid cleaved at the γ-hydroxylysine residue to give two peptide fragments, one of which (the N-terminal side) was then deacylated with Polymyxin Acylase. Their amino acid sequences were examined by EDMAN degradation. From the results and analogy to cerexin A, the structure of cerexin B was deduced.
Graphitization Mechanism during the Carbon-Nanotube Formation Based on the In-Situ HRTEM Observation (2002)

The mechanism of the carbon nanotube (CNT) formation and its graphitization has not been well understood and is still under controversy. The authors have been studying a new process to form CNTs, where polyyne-containing carbons are heated and irradiated by an electron beam in a transmission electron microscope (TEM). The technique is compatible to an in-situ observation and was applied to a high-resolution TEM (HRTEM) to elucidate the graphitization mechanism. The observation shows that micro-graphenes exist from the beginning of the formation process and develop to form highly ordered graphene layers through fusion and rearrangement of the premature layers, accompanied by evaporation of micro-graphenes. The CNT formation mechanism focusing on its graphitization is presented and discussed.
Reactions of relevance to the chemistry of aminoglycoside antibiotics. Part 14. A useful radical-deamination reaction (1980)

Primary, secondary, and tertiary aliphatic or alicyclic isocyanides are smoothly reduced under radical conditions using tri-n-butylstannane to the corresponding hydrocarbons. The relative ease of reduction is tertiary > secondary > primary. Aromatic isocyanides are not reduced under these conditions. The reduction of isothiocyanates (or isoselenocyanates) by tri-n-butylstannane also affords hydrocarbons, but here the isocyanides have been shown to be intermediates. The reduction of a compound with isocyanide and xanthate functions in a 1,2-relationship gives a smooth radical fragmentation to furnish an olefin. An efficient synthesis of 2-deoxy-D-glucose starting with glucosamine is described.

Upregulation of an Arabidopsis RING‐H2 gene, XERICO, confers drought tolerance through increased abscisic acid biosynthesis (2006)

RING (really interesting new gene) zinc-finger proteins have important regulatory roles in the development of a variety of organisms. The XERICO gene encodes a small protein (162 amino acids) with an N-terminal trans-membrane domain and a RING-H2 zinc-finger motif located at the C-terminus. In silico gene-expression analysis indicated that XERICO is induced by salt and osmotic stress. Compared with wild-type (WT) Arabidopsis plants, transgenic plants overexpressing XERICO (35S::XERICO) exhibited hypersensitivity to salt and osmotic stress and exogenous abscisic acid (ABA) during germination and early seedling growth. When subjected to a drought treatment, transcriptional upregulation of a key ABA-biosynthesis gene, AtNCED3, was much faster and stronger in 35S::XERICO plants compared with WT plants. Further, upregulation of XERICO substantially increased cellular ABA levels. The adult 35S::XERICO plants, in contrast to early seedling growth, showed a marked increase in their tolerance to drought stress. Yeast two-hybrid screening indicated that XERICO interacts with an E2 ubiquitin-conjugating enzyme (AtUBC8) and ASK1-interacting F-box protein (AtTLP9), which is involved in the ABA-signaling pathway. Affymetrix GeneChip array analysis showed that the expressions of many of the genes involved in the biosynthesis of plant hormones (e.g. ethylene, brassinosteroid, gibberellic acid) were significantly changed in the 35S::XERICO plants. These results suggest that the homeostasis of various plant hormones might be altered in 35S::XERICO plants, possibly by overaccumulation of ABA.
A framework to predict the quality of answers with non-textual features (2006)

New types of document collections are being developed by various web services. The service providers keep track of non-textual features such as click counts. In this paper, we present a framework to use non-textual features to predict the quality of documents. We also show our quality measure can be successfully incorporated into the language modeling-based retrieval model. We test our approach on a collection of question and answer pairs gathered from a community based question answering service where people ask and answer questions. Experimental results using our quality measure show a significant improvement over our baseline.
Integrated Measurement of the Mass and Surface Charge of Discrete Microparticles Using a Suspended Microchannel Resonator (2009)

Measurements of the mass and surface charge of microparticles are employed in the characterization of many types of colloidal dispersions. The suspended microchannel resonator (SMR) is capable of measuring individual particle masses with femtogram resolution. Here, we employ the high sensitivity of the SMR resonance frequency to changes in particle position, relative to the cantilever tip, to determine the electrophoretic mobility of discrete particles in an applied electric field. When a sinusoidal electric field is applied to the suspended microchannel, the transient resonance frequency shift corresponding to a particle transit can be analyzed by digital signal processing to extract both the buoyant mass and electrophoretic mobility of each particle. These parameters, together with the mean particle density, can be used to compute the size, absolute mass, and surface charge of discrete microspheres, leading to a true representation of the mean and polydispersity of these quantities for a population. We have applied this technique to an aqueous suspension of two types of polystyrene microspheres, to differentiate them based on their absolute mass and their surface charge. The integrated measurement of electrophoretic mobility using the SMR is determined to be quantitative, based on comparison with commercial instruments, and exhibits favorable scaling properties that will ultimately enable measurements from mammalian cells.
Endothelial apoptotic activity of angiocidin is dependent on its polyubiquitin binding activity (2005)

We recently cloned the full-length cDNA of a tumour-associated protein. The recombinant protein expressed in bacteria and referred to as angiocidin has potent antitumour activity in vivo and in vitro. Angiocidin inhibits tumour growth and angiogenesis by inducing apoptosis in endothelial cells. Based on the sequence similarity of angiocidin to S5a, one of the major polyubiquitin recognition proteins in eukaryotic cells, we postulated that the antiendothelial activity of angiocidin could be due in part to its polyubiquitin binding activity. In support of this hypothesis, we show that angiocidin binds polyubiquitin in vivo with high affinity and colocalises with ubiquitinated proteins on the surface of endothelial cells. Binding is blocked with an antiubiquitin antibody. Angiocidin treatment of endothelial cells transfected with a proteasome fluorescent reporter protein showed a dose-dependent inhibition of proteasome activity and accumulation of polyubiquitinated proteins. Full-length angiocidin bound polyubiquitin while three angiocidin recombinant proteins whose putative polyubiquitin binding sites were mutated either failed to bind polyubiquitin or had significantly diminished binding activity. The in vitro apoptotic activity of these mutants correlated with their polyubiquitin binding activity. These data strongly argue that the apoptotic activity of angiocidin is dependent on its polyubiquitin binding activity.
Recent Progress in the Study of Microbiomineralogy of Feldspar (2008)

Interactions between minerals and microorganisms, especially microbial weatherng of silicates which has been concerned much for its important significance in circulation of matters and evolution of topography, are important processes in subsurface of the Earth. As the most popular silicate on the Earth's surface, feldspar usually undergoes microbial weathering through three models: the fluid model, the biofilm and fungal hyphae. Usually, microorganisms can enhance decomposing feldspar by the proton-and ligand-promoted mechanisms. The rate and degree for microbial weathering of feldspar are always affected by many factors such as physiological behaviors of microorganism, category of microorganisms and metabolites, growth condition and category, structure, composition of feldspar as well. It is believed that the researches on models, mechanisms, impact factors of interactions bewteen feldspar and microorganisms are very instructive in the investigaton of the geomicrobiology of silicate.
