Pain and Its Treatments (1997)

Among many relevant topics concerning pain and its treatments, the following will be considered: (1) definition of pain; (2) physiopathology; (3) methodology for clinical trials in pain research (4) use of drugs and surgical management of pain, and (5) future directions. The definition of pain as an unpleasant subjective, sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage, does not apply to living people incapable of self-report. Thus, nonverbal behavioral information is often needed and used for pain assessment. Major landmarks concerning physiopathology were: the liberation of substance P and other neuropeptides both at the spinal and peripheral endings, the anatomical and functional analysis of the nociceptive pathways, the characterization of endomorphins ligands and receptors. The difference between 'windup' and central sensitization were emphasized. Models of neuropathic pain have advanced our understanding of its specific pathophysiology. Sensoridiscriminative aspects of pain involve lateral thalamic nuclei and corresponding somesthetic cortices, whereas medial thalamic nuclei encode nociceptive stimuli during attention-directed tasks. Their cortical connections, namely anterior cingular cortex and insular cortex, support the postulate of a role in the affective-motivational dimensions of pain. An impressive increase in the number and quality of randomised clinical trials has been observed since 1950. The use of analgesics, opioids, antidepressants and other drugs is addressed, as well as new aspects concerning surgery or new drugs.
A New Synthetic Test Circuit for Testing Thyristor Valve in HVDC Converter (2012)

This paper proposes a new synthetic test circuit (STC) to confirm the switching operation of thyristor valve in HVDC converter. The proposed STC uses a 6-pulse thyristor converter with 2-phase chopper as a high-current source to provide turn-on current to the test valve. The operation of proposed STC was verified through theoretical analysis and computer simulations. Based on computer simulations, a hardware scaled model was built and tested to confirm the feasibility of implementing a real-size test facility. The proposed system has an advantage of simple structure and operation over the existing system.

Effects of anesthesia-induced modest hypothermia on cellular radiation sensitivity (2002)

To assess the mechanisms of modest hypothermia (MH) and its effects on cellular radiation response, a model of anesthesia-induced modest hypothermia (AIMH) in the adult mice and a model of pure MH in the newborn mice were established. The survival rate of lethally irradiated mice was increased to 72% through AIMH before irradiation. Both apoptosis and necrosis of human fetal bone marrow CD34(+) hematopoietic stem cells cultured under MH were significantly decreased as detected by MTT and flow cytometry, with three-color labeled by PE-CD(34) (+)/ FITC-AnnexinV /7AAD. The survival and proliferation of mouse bone marrow MNC treated with MH after irradiation were also increased. The MH exerted similar protective effects on the leukemia cell lines A20, HL60, K562 to the normal bone marrow cells, but it enhanced the radiation sensitivity of leukemia cell line FBL3 and mouse melanoma B16F10. No effects have been found on the radiation sensitivity of those cells treated with MH before irradiation. The results also showed that MH mediated the effects on radiation sensitivity, in addition to increasing the oxygen tension. These results show different effects of MH on different cells: (i) AIMH exerts a protective effect on the normal hematopoietic stem cells, some leukemia cell lines A20, HL60, K562, and some neoplasma 3LL, LOVO. And MH exhibits a synthetic effect with anesthetic. (ii) MH enhances the radiation sensitivity of another leukemia and neoplasma cell lines FBL3, B16F10 and CT26. Therefore, AIMH has a potential to enhance the effects of radiation-therapy and decrease side effects on some tumors.

Personalized medicine in metastatic non-small-cell lung cancer: promising targets and current clinical trials (2012)

Non-small-cell lung cancer (nsclc) remains the leading cause of cancer-related death globally, with most patients presenting with non-curable disease. Platinum-based doublet chemotherapy has been the cornerstone of treatment for patients with advanced-stage disease and has resulted in a modest increase in overall survival (on the order of an incremental 2 months increased survival per decade) and quality of life. Improved knowledge of the molecular signalling pathways found in nsclc has led to the development of biomarkers with associated targeted therapeutics, thus changing the treatment paradigm for many nsclc patients. In this review, we present a summary of many of the currently investigated nsclc targets, discuss their current clinical trial status, and provide commentary as to the likelihood of their success making a positive impact for nsclc patients.
Novel Method to Quantify Neuropil Threads in Brains from Elders With or Without Cognitive Impairment (2000)

Pathological alterations in dendrites and axons (i.e., neuritic pathologies) occur in the normal aging brain as well as in brains from elders with mild cognitive impairment and neurodegenerative dementia. These alterations may correlate with clinical measures of cognitive abilities, but the contribution of neuropil threads (NTs), which constitute 85-90% of cortical tau pathology, has not been clear because of the lack of quantitative methodologies. We combined quantitative fractionation and image analysis to devise a strategy for measuring the burden of tau-rich NTs in the entorhinal and perirhinal cortex of brains from elders with and without cognitive impairment, including dementia due to Alzheimer's disease (AD). On the basis of data presented here using this novel strategy, we conclude that this quantitative imaging technique will facilitate efforts to determine the behavioral correlations of neuritic lesions in AD and other brain disorders.
Comparative analysis of carboxysome shell proteins (2011)

Carboxysomes are metabolic modules for CO(2) fixation that are found in all cyanobacteria and some chemoautotrophic bacteria. They comprise a semi-permeable proteinaceous shell that encapsulates ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and carbonic anhydrase. Structural studies are revealing the integral role of the shell protein paralogs to carboxysome form and function. The shell proteins are composed of two domain classes: those with the bacterial microcompartment (BMC; Pfam00936) domain, which oligomerize to form (pseudo)hexamers, and those with the CcmL/EutN (Pfam03319) domain which form pentamers in carboxysomes. These two shell protein types are proposed to be the basis for the carboxysome's icosahedral geometry. The shell proteins are also thought to allow the flux of metabolites across the shell through the presence of the small pore formed by their hexameric/pentameric symmetry axes. In this review, we describe bioinformatic and structural analyses that highlight the important primary, tertiary, and quaternary structural features of these conserved shell subunits. In the future, further understanding of these molecular building blocks may provide the basis for enhancing CO(2) fixation in other organisms or creating novel biological nanostructures.
Spectroscopic behavior of halogen photodesorption from alkali halidesunder UV and VUV excitation (1997)

The photostimulated desorption yield of neutral halogen atoms from KI, KBr, and RbI at several temperatures has been measured in the photon energy range between 5 and 30 eV using synchrotron radiation and quadrupole mass spectrometry. The features observed in the desorption yield are slightly correlated with the structures of the absorption spectra of each investigated material. The behavior of the halogen desorption yield is analyzed in the frame of inelastic electron-electron scattering processes, in close analogy with data available from the total photoelectron yield and the luminescence yield. The role played in the desorption mechanism by fundamental excitations, such as valence exciton creation and band-gap electron-hole excitation, is discussed.
Identification and Expression of a 50-Kilodalton Surface Antigen of<i>Babesia gibsoni</i>and Evaluation of Its Diagnostic Potential in an Enzyme-Linked Immunosorbent Assay (2001)

A cDNA expression library prepared from Babesia gibsoni merozoite mRNA was screened with B. gibsoni-infected dog serum. cDNA encoding a 50-kDa protein was cloned and designated the P50 gene. The complete nucleotide sequence of the P50 gene was 1,922 bp. Computer analysis suggested that the sequence of the P50 gene contained an open reading frame of 1,401 bp with a coding capacity of approximately 50 kDa. The complete genomic nucleotide sequence of the P50 gene has been analyzed and shown to contain a single intron of 37 bp. Southern blotting analysis indicated that the P50 gene was present at a single copy in the B. gibsoni genome. The native P50 protein of B. gibsoni with a molecular mass of 50 kDa was identified by Western blotting with anti-recombinant P50 mouse serum. Confocal laser microscopic analysis showed that the P50 protein was located on the surface of B. gibsoni merozoites. The recombinant P50 protein expressed by baculovirus in insect cells was used as the antigen in an enzyme-linked immunosorbent assay (ELISA). The ELISA was able to differentiate between B. gibsoni-infected dog serum and B. canis-infected dog serum or noninfected dog serum. Furthermore, the antibody response against the recombinant P50 protein was maintained until the chronic stage of infection in dogs experimentally infected with B. gibsoni was developed. These results demonstrate that the recombinant P50 protein might be a useful diagnostic reagent for detection of antibodies to B. gibsoni in dogs.
The orthogonal-transfer array: a new CCD architecture for astronomy (2004)

The orthogonal-transfer array (OTA) is a new CCD architecture designed to provide wide-field tip-tilt correction of astronomical images. The device consists of an 8x8 array of small (~500x500 pixels) orthogonal-transfer CCDs (OTCCD) with independent addressing and readout of each OTCCD. This approach enables an optimum tip-tilt correction to be applied independently to each OTCCD across the focal plane. The first design of this device has been carried out at MIT Lincoln Laboratory in support of the Pan-STARRS program with a collaborative parallel effort at Semiconductor Technology Associates (STA) for the WIYN Observatory. The two versions of this device are functionally compatible and share a common pinout and package. The first wafer lots are complete at Lincoln and at Dalsa and are undergoing wafer probing.
Phosphorylation‐dependent activation of TAK1 mitogen‐activated protein kinase kinase kinase by TAB1 (2000)

TAK1 is a mitogen-activated protein kinase kinase kinase (MAP3K) that is involved in the c-Jun N-terminal kinase/p38 MAPKs and NF-kappaB signaling pathways. Here, we characterized the molecular mechanisms of TAK1 activation by its specific activator TAB1. Autophosphorylation of two threonine residues in the activation loop of TAK1 was necessary for TAK1 activation. Association with TAK1 and induction of TAK1 autophosphorylation required the C-terminal 24 amino acids of TAB1, but full TAK1 activation required additional C-terminal Ser/Thr rich sequences. These results demonstrated that the association between the kinase domain of TAK1 and the C-terminal TAB1 triggered the phosphorylation-dependent TAK1 activation mechanism.
Surface Micromachined Micro-Pressure-Sensor (1992)

A new micro-pressure-sensor with diaphragm size of 100μm has been fabricated by a surface micromachining technique. A circular diaphragm with 1.6μm in thickness, supported at its edge and center, was adopted to decrease the stress concentration at the diaphragm edge. The diaphragm was formed flat-structure by an etch-stop technique of a polysilicon sacrificial layer. The most suitable arrangement of piezoresistors was determined by FEM (Finite Element Method) stress analysis of the diaphragm. A pressure sensitivity of 20 μV/kPa for a pressure range from 60 to 110 kPa absolute, and a temperature coefficient of the sensitivity of -0.26% F. S./°C for a temperature range from -30 to 85°C were obtained.
VQA: Visual Question Answering (2015)

We propose the task of free-form and open-ended Visual Question Answering (VQA). Given an image and a natural language question about the image, the task is to provide an accurate natural language answer. Mirroring real-world scenarios, such as helping the visually impaired, both the questions and answers are open-ended. Visual questions selectively target different areas of an image, including background details and underlying context. As a result, a system that succeeds at VQA typically needs a more detailed understanding of the image and complex reasoning than a system producing generic image captions. Moreover, VQA is amenable to automatic evaluation, since many open-ended answers contain only a few words or a closed set of answers that can be provided in a multiple-choice format. We provide a dataset containing ~0.25M images, ~0.76M questions, and ~10M answers (www.visualqa.org), and discuss the information it provides. Numerous baselines and methods for VQA are provided and compared with human performance. Our VQA demo is available on CloudCV (http://cloudcv.org/vqa).

Regulation of neurotrophin receptor expression during embryonic and postnatal development (1994)

Members of the NGF family of proteins act as neurotrophic agents for defined populations of peripheral and central neurons during embryonic and postnatal development. We have studied the presence of receptors for brain-derived neurotrophic factor (BDNF) and neurotrophin-3 and -4/5 (NT-3, NT-4/5) by cross-linking radioiodinated neurotrophins to specific cell surface receptors. We have identified neurotrophin receptors representing full-length TrkB and TrkC and their truncated forms (lacking a functional cytoplasmic kinase domain) in neuronal as well as in non-neuronal tissues. During chicken embryonic and early postnatal brain development, expression of full-length TrkB and TrkC proteins preceded the onset of the truncated forms of these receptors. A similar pattern was also observed in mouse embryonic and early postnatal brain. The relative levels of neurotrophin receptors in the basal forebrain and in the hippocampus did not change significantly with age in mice. High levels of receptors for the three neurotrophins were detected in the nigrostriatal system. Full-length TrkB and TrkC receptors were found in chicken and rat embryonic ventral spinal cord, as well as on purified motoneurons. Again, truncated TrkB appeared significantly later than the full-length form on spinal motoneurons. In chicken embryonic retina and optic tectum we detected full-length TrkB and TrkC; however, the optic tectum also expressed large amounts of the truncated form of TrkB. TrkC but not TrkB was detected in chicken embryonic skeletal muscle, suggesting that NT-3 may have a novel function in this tissue. The presence of neurotrophin receptors in a wide variety of embryonic and postnatal tissues underlines the significant role of BDNF, NT-3, and NT-4/5 in embryonic and postnatal development. The regulation of the ratio of full-length versus truncated neurotrophin receptors may play an important role in the development, maturation, and maintenance of various neuronal networks.
Phylogenetic conservatism of functional traits in microorganisms (2012)

A central question in biology is how biodiversity influences ecosystem functioning. Underlying this is the relationship between organismal phylogeny and the presence of specific functional traits. The relationship is complicated by gene loss and convergent evolution, resulting in the polyphyletic distribution of many traits. In microorganisms, lateral gene transfer can further distort the linkage between phylogeny and the presence of specific functional traits. To identify the phylogenetic conservation of specific traits in microorganisms, we developed a new phylogenetic metric-consenTRAIT-to estimate the clade depth where organisms share a trait. We then analyzed the distribution of 89 functional traits across a broad range of Bacteria and Archaea using genotypic and phenotypic data. A total of 93% of the traits were significantly non-randomly distributed, which suggested that vertical inheritance was generally important for the phylogenetic dispersion of functional traits in microorganisms. Further, traits in microbes were associated with a continuum of trait depths (τD), ranging from a few deep to many shallow clades (average τD: 0.101-0.0011 rRNA sequence dissimilarity). Next, we demonstrated that the dispersion and the depth of clades that contain a trait is correlated with the trait's complexity. Specifically, complex traits encoded by many genes like photosynthesis and methanogenesis were found in a few deep clusters, whereas the ability to use simple carbon substrates was highly phylogenetically dispersed. On the basis of these results, we propose a framework for predicting the phylogenetic conservatism of functional traits depending on the complexity of the trait. This framework enables predicting how variation in microbial composition may affect microbially-mediated ecosystem processes as well as linking phylogenetic and trait-based patterns of biogeography.
