Author Profiling for English and Arabic Emails (2008)

This paper reports on some aspects of a research project aimed at automating the analysis of texts for the purpose of author profiling and identification. The Text Attribution Tool (TAT) was developed for the purpose of language-independent author profiling and has now been trained on two email corpora, English and Arabic. The complete analysis provides probabilities for the author’s basic demographic traits (gender, age, geographic origin, level of education and native language) as well as for five psychometric traits. The prototype system also provides a probability of a match with other texts, whether from known or unknown authors. A very important part of the project was the data collection and we give an overview of the collection process as well as a detailed description of the corpus of email data which was collected. We describe the overall TAT system and its components before outlining the ways in which the email data is processed and analysed. Because Arabic presents particular challenges for NLP, this paper also describes more specifically the text processing components developed to handle Arabic emails. Finally, we describe the Machine Learning setup used to produce classifiers for the different author traits and we present the experimental results, which are promising for most traits examined.
Inflammatory Cell Migration into the Central Nervous System: A Few New Twists on an Old Tale (2007)

Understanding the mechanisms of leukocyte trafficking into the brain might provide insights into how to modulate pathologic immune responses or enhance host protective mechanisms in neuroinflammatory diseases such as multiple sclerosis. This review summarized our knowledge about the sites for leukocyte entry into the central nervous system, highlighting the routes from blood into the perivascular space and brain parenchyma through the blood-brain barrier. We further discussed the multistep paradigm of leukocyte-endothelial interactions at the blood-brain barrier, focusing on the adhesion molecules and chemokines involved in leukocyte transmigration. Luminal chemokines, which are immobilized on endothelial surfaces, initiate leukocyte integrin clustering and conformational change, leading to leukocyte arrest. Some leukocytes undergo post-arrest locomotion across the endothelial surface until interendothelial junctions are identified. Leukocytes then extend protrusions through the interendothelial junctions, in search of abluminal chemokines, which will serve as guidance cues for transmigration. Extravasating cells first accumulate in the perivascular space between the endothelial basement membrane and the basement membrane of the glia limitans. Matrix metalloproteases may be involved in leukocyte transverse across glia limitans into the brain parenchyma. The adhesion molecules and chemokine receptors provide attractive targets for neuroinflammatory diseases because of their important role in mediating central nervous system inflammation.
Medical Expenditures for the Treatment of Osteoporotic Fractures in the United States in 1995: Report from the National Osteoporosis Foundation (1997)

Osteoporotic fractures are a significant public health problem, resulting in substantial morbidity and mortality. Previous estimates of the economic burden of osteoporosis, however, have not fully accounted for the costs associated with treatment of nonhip fractures, minority populations, or men. Accordingly, the 1995 total direct medical expenditures for the treatment of osteoporotic fractures were estimated for all persons aged 45 years or older in the United States by age group, sex, race, type of fracture, and site of service (inpatient hospital, nursing home, and outpatient). Osteoporosis attribution probabilities were used to estimate the proportion of health service utilization and expenditures for fractures that resulted from osteoporosis. Health care expenditures attributable to osteoporotic fractures in 1995 were estimated at $13.8 billion, of which $10.3 billion (75.1%) was for the treatment of white women, $2.5 billion (18.4%) for white men, $0.7 billion (5.3%) for nonwhite women, and $0.2 billion (1.3%) for nonwhite men. Although the majority of U.S. health care expenditures for the treatment of osteoporotic fractures were for white women, one-fourth of the total was borne by other population subgroups. By site-of-service, $8.6 billion (62.4%) was spent for inpatient care, $3.9 billion (28.2%) for nursing home care, and $1.3 billion (9.4%) for outpatient services. Importantly, fractures at skeletal sites other than the hip accounted for 36.9% of the total attributed health care expenditures nationally. The contribution of nonhip fractures to the substantial morbidity and expenditures associated with osteoporosis has been underestimated by previous researchers.

Dissecting the Salmonella response to copper (2007)

Intracellular copper homeostasis in bacteria is maintained as the result of a complex ensemble of cellular processes that in Escherichia coli involve the coordinated action of two systems, cue and cus. In contrast, the pathogenic bacterium Salmonella harbours only the cue regulon, including copA, which is shown here to be transcriptionally controlled by CueR. Mutant strains in the CueR-regulated genes were constructed to characterize the response of Salmonella enterica serovar Typhimurium to high concentrations of extracellular copper under both aerobic and anaerobic conditions. Unlike its counterpart in E. coli, inactivation of cuiD displays the most severe phenotype and is also required for copper tolerance under anaerobic conditions. Deletion of copA has a mild effect in aerobiosis, but strongly impairs survival in the absence of oxygen. In a DeltacopA strain, a second Salmonella-specific P-type ATPase, GolT, can substitute the copper transporter, diminishing the effect of its deletion. The overall results highlight the importance of the cue system for controlling intracellular copper stress. The observed differences between Salmonella and E. coli in handling copper excess may contribute to our understanding of the distinct capability of these related pathogenic bacteria to survive outside the host.
TROP2 expression as prognostic marker for gastric carcinoma (2008)

Results show that TROP2 is an independent prognostic marker for disease recurrence in intestinal type gastric cancer. Due to its wide distribution TROP2 may become an attractive therapeutic target in a subgroup of patients with gastric cancer.
A Comparison of Clozapine and Haloperidol in Hospitalized Patients with Refractory Schizophrenia (1997)

For patients with refractory schizophrenia and high levels of hospital use, clozapine was somewhat more effective than haloperidol and had fewer side effects and similar overall costs.
Comparison of postoperative radiotherapy and combined postoperative radiotherapy and chemotherapy in the multidisciplinary management of malignant gliomas. A joint radiation therapy oncology group and eastern cooperative oncology group study (1983)

Recently, the RTOG and ECOG concluded a joint randomized study on malignant gliomas that was in progress for the past five years. A total of 626 patients entered this protocol. Sixty-seven percent of the 535 evaluable patients have died and thus this represents a preliminary report of a major joint clinical trial. The objective of this study was to evaluate the efficacy after neurosurgery of three new treatment options as compared with control treatment of radiotherapy alone. The four options were: (1) control radiation; 6000 rad/6-7 weeks to whole brain; (2) a higher radiation dose; Control dose plus a booster dose of 1000 rad/1-2 weeks to the tumor; (3) control radiation dose plus BCNU (80 mg/m2/day IV X 3 and repeat BCNU every 8 weeks); (4) Control radiation dose plus combination methyl-CCNU (125 mg/m2/day orally X 1 and repeat methyl-CCNU every 8 weeks), and DTIC (150 mg/m2/day IV X 5 and repeat DTIC every 4 weeks). All pertinent patient characteristics were studied and several important prognostic factors have been identified. Notably, age, histologic type (Astrocytoma with anaplastic foci, versus glioblastoma multiforme), initial performance status, time since first symptoms and presence or absence of seizure. At this time, it appeared that there was no treatment option which was significantly better than the control. The study identified that age was the most important prognostic factor. Patients who were younger than age 40 years had an 18-month survival of 64%, patients who were age 40-60 years had an 18-month survival of 20%, and patients who were older than age 60 had an 18-month survival of 8%. The study also demonstrated that a modified histologic classification of anaplastic astrocytoma versus glioblastoma provided better prognostic information than the astrocytoma grading system of Kernohan. Patients with anaplastic astrocytoma had a median survival of 27 months as compared to 8 months for patients with glioblastoma. In further evaluation of any beneficial effect of chemotherapy, it was identified that only among the 40-60-year-old groups, BCNU treated patients appeared to have significantly increased survival than patients in the control groups (P = 0.01, one-sided). Similarly, methyl-CCNU + DTIC was suggestively better than the control (P = 0.08, one-sided). The higher radiation dose, 7000 rad/8-9 weeks appeared to give no significantly better survival over the control dose option. Both BCNU and methyl-CCNU + DTIC produced some toxicity. The combination of methyl-CCNU + DTIC was more toxic than BCNU, producing severe or worse thrombocytopenia in 23% of the patients as compared to 6% on BCNU.

Physiologic Decline in Fetal Hemoglobin Parameters in Infants With Sickle Cell Disease (1999)

By age 2 years, HbF parameters including the % HbF, % F cells, and the HbF per F cell decrease to levels insufficient to inhibit sickling. Pharmacologic intervention designed to enhance HbF production and prevent chronic organ damage should be considered during infancy.
Speciation of protein‐bound trace elements by gel electrophoresis and atomic spectrometry (2004)

The metabolism of trace elements, in particular their binding to proteins in biological systems is of great importance in biochemical, toxicological, and pharmacological studies. As a result there has been a sustained interest over the last two decades in the speciation of protein-bound metals. Various analytical approaches have been employed, combining efficient separation of metalloproteins by liquid chromatography or electrophoresis with high-sensitivity elemental detection. Slab-gel electrophoresis (GE) is a key platform for high-resolution protein separation, and has been combined with autoradiography and various atomic spectrometric techniques for in-gel determination of protein-bound metals. Recently, the combination of GE with state-of-the-art inductively coupled plasma-mass spectrometry (ICP-MS), particularly when linked to laser ablation (LA) for direct gel interrogation, has opened up new opportunities for rapid characterization of metalloproteins. The use of GE and atomic spectrometry for the speciation of protein-bound trace elements is reviewed in this paper. Technical requirements for gel electrophoresis/atomic spectrometric measurement are considered in terms of method compatibilities, detection capability and potential usefulness. The literature is also surveyed to illustrate current status and future trends.
An adaptive ARQ scheme using pragmatic TCM (2002)

We propose an adaptive automatic repeat request (ARQ) scheme using pragmatic trellis-coded modulations (TCMs) and soft-decision Viterbi decoding. The scheme adapts to the changing channel noise condition by selecting the TCM with a code rate which best matches the current channel signal-to-noise ratio (SNR). A simple and yet efficient algorithm for estimating channel SNR is also proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Tissue-Based Proteogenomics Reveals that Human Testis Endows Plentiful Missing Proteins (2015)

Investigations of missing proteins (MPs) are being endorsed by many bioanalytical strategies. We proposed that proteogenomics of testis tissue was a feasible approach to identify more MPs because testis tissues have higher gene expression levels. Here we combined proteomics and transcriptomics to survey gene expression in human testis tissues from three post-mortem individuals. Proteins were extracted and separated with glycine- and tricine-SDS-PAGE. A total of 9597 protein groups were identified; of these, 166 protein groups were listed as MPs, including 138 groups (83.1%) with transcriptional evidence. A total of 2948 proteins are designated as MPs, and 5.6% of these were identified in this study. The high incidence of MPs in testis tissue indicates that this is a rich resource for MPs. Functional category analysis revealed that the biological processes that testis MPs are mainly involved in are sexual reproduction and spermatogenesis. Some of the MPs are potentially involved in tumorgenesis in other tissues. Therefore, this proteogenomics analysis of individual testis tissues provides convincing evidence of the discovery of MPs. All mass spectrometry data from this study have been deposited in the ProteomeXchange (data set identifier PXD002179).
Role of ROBO4 Signalling in Developmental and Pathological Angiogenesis (2014)

Transmembrane roundabout receptor family members (ROBO1-ROBO4) principally orchestrate the neuronal guidance mechanism of the nervous system. Secreted glycoprotein SLITs are the most appreciated ligands for ROBOs. Recently identified ROBO4 is the key mediator of SLIT-ROBO mediated developmental and pathological angiogenesis. Although SLIT2 has been shown to interact with ROBO4 as ligand, it remains an open question whether this protein is the physiologic partner of ROBO4. The purpose of this review is to summarise how reliable SLIT2 as ligand for ROBO4 is, if not what the other possible mechanisms demonstrated till date for ROBO4 mediated developmental and pathological angiogenesis are. We conclude that ROBO4 is expressed specially in vascular endothelial cells and maintains the vascular integrity via either SLIT2 dependent or SLIT2 independent manner. On the contrary, it promotes the pathological angiogenesis by involving different signalling arm(s)/unknown ligand(s). This review explores the interactions SLIT2/ROBO1, SLIT2/ROBO1-ROBO4, ROBO1/ROBO4, and ROBO4/UNC5B which can be promising and potential therapeutic targets for developmental angiogenesis defects and pathological angiogenesis. Finally we have reviewed the ROBO4 signalling pathways and made an effort to elaborate the insight of this signalling as therapeutic target of pathological angiogenesis.
Enzyme-linked immunosorbent assay for detection of specific antibodies to Ureaplasma urealyticum serotypes (1984)

Optimal conditions of a micro-enzyme-linked immunosorbent assay system for the detection of immunoglobulin G antibodies to Ureaplasma urealyticum were established with rabbit antisera. Initially, the antisera, raised against eight U. urealyticum serotypes grown on medium containing horse serum, displayed nonspecific reactions with our enzyme-linked immunosorbent assay antigens. Substitution of fetal bovine serum in the medium eliminated this nonspecificity. The assay was then serotype-specific for the original eight U. urealyticum serotypes. The prominent homologous reaction was easily differentiated from the heterologous reactions. A one-way cross-reaction was observed with serotype 2 antiserum and serotype 5 antigen. The results were reproducible and could be obtained in 4 h with only 10 microliters of serum for eight serotypes. Optimal antigen concentrations for the U. urealyticum serotypes ranged from 0.40 to 1.60 micrograms/ml. Our results indicated that enzyme-linked immunosorbent assay has the potential for the detection of antibodies to specific serotypes of U. urealyticum.
Quantification of third-body damage and its effect on UHMWPE wear with different types of femoral head (1998)

We examined stainless-steel, cobalt-chrome, titanium and alumina and zirconia ceramic femoral heads retrieved at revision surgery. All the heads had articulated against ultra-high-molecular-weight-polyethylene (UHMWPE) acetabular cups. We studied the simulation of third-body damage and the wear of UHMWPE against the various materials used for the heads. The surfaces of the retrieved heads were analysed using a two-dimensional contacting profilometer. Third-body damage was characterised by the mean height of the scratches above the mean line (Rpm). The alumina ceramic and zirconia ceramic retrieved heads were found to have significantly less damage. In laboratory studies the ceramics were also more resistant to simulated third-body damage than the metal alloys. We studied the wear of UHMWPE against the damaged counterfaces in simple configuration tests. The damaged ceramics produced less polyethylene wear than the damaged metal counterfaces. The wear factor of UHMWPE against the damaged materials was dependent on the amount of damage to the counterface (Rp). Our study has shown the benefit of using the harder and more damage-resistant ceramic materials for femoral heads.
Cell-Permeable Near-Infrared Fluorogenic Substrates for Imaging β-Lactamase Activity (2005)

This communication describes a design of cell-permeable near-infrared fluorogenic substrates for imaging beta-lactamase expression in living mammalian cells. This design is based on fluorescence energy transfer resonance and utilizes a peracetylated d-glucosamine to facilitate the transport of the near-infrared probe across cell membranes. This new type of fluorogenic probe may also be applied to image gene expression in living animals.
Uteroglobin Suppresses SCCA Gene Expression Associated with Allergic Asthma (2005)

Uteroglobin (UG), the founding member of the Secretoglobin superfamily, is a potent anti-inflammatory protein constitutively expressed at a high level in the airway epithelia of all mammals. We previously reported that the lungs of UG-knock-out (UG-KO) mice express elevated levels of Th2 cytokines (e.g. interleukin (IL)-4 and IL-13), which are augmented by allergen sensitization and challenge leading to exaggerated airway inflammation. Notably, these responses are suppressed by recombinant UG treatment (Mandal, A. K., Zhang, Z., Ray, R., Choi, M. S., Chowdhury, B., Pattabiraman, N., and Mukherjee, A. B. (2004) J. Exp. Med. 199, 1317-1330). Recent reports indicate that human orthologs of murine squamous cell carcinoma antigen-2 (SCCA-2/serpinb3a), a serine protease-inhibitor, are overexpressed in the airways of asthmatic patients. We report here that compared with wild type littermates, UG-KO mouse lungs express markedly elevated levels of SCCA-2 mRNA and protein, which are augmented by allergen-challenge. Most importantly, these effects are abrogated by recombinant UG treatment. We further demonstrate that treatment of cultured human bronchial epithelial cells with IL-4 or IL-13 stimulates phosphorylation of STAT-1 and STAT-6 leading to SCCA-1 (SERPINB3) and SCCA-2 (SERPINB4) gene expression. We propose that: (i) IL-4- and IL-13-stimulated SCCA gene expression is mediated via STAT-1 and STAT-6 activation, and (ii) by suppressing the production, and most likely by interfering with the signaling of these cytokines, UG inhibits SCCA gene expression associated with airway inflammation in asthma.
Olivocochlear innervation in the mouse: Immunocytochemical maps, crossed versus uncrossed contributions, and transmitter colocalization (2002)

To further understand the roles and origins of gamma-aminobutyric acid (GABA) and calcitonin gene-related peptide (CGRP) in the efferent innervation of the cochlea, we first produced in the mouse an immunocytochemical map of the efferent terminals that contain acetylcholine (ACh), CGRP, and GABA. Olivocochlear (OC) terminals in inner and outer hair cell (IHC and OHC) regions were analyzed quantitatively along the cochlear spiral via light-microscopic observation of cochlear wholemounts immunostained with antibodies to glutamic acid decarboxylase (GAD), vesicular acetylcholine transporter (VAT), or the peptide CGRP. Further immunochemical characterization was performed in mice with chronic OC transection at the floor of the fourth ventricle to distinguish crossed from uncrossed contributions and, indirectly, the contributions of lateral versus medial components of the OC system. The results in mouse showed that (1) there are prominent GABAergic, cholinergic, and CGRPergic innervations in the OHC and IHC regions, (2) GABA and CGRP are extensively colocalized with ACh in all OC terminals in the IHC and OHC areas, (3) the longitudinal gradient of OC innervation peaks roughly at the 10-kHz region in the OHC area and is more uniform along the cochlear spiral in the IHC area, (4) in contrast to other mammalian species there is no radial gradient of OC innervation of the OHCs, and (5) all OHC efferent terminals arise from the medial OC system and terminals in the IHC area arise from the lateral OC system.
Recombination signal sequence-binding protein Jκ alters mesodermal cell fate decisions by suppressing cardiomyogenesis (2003)

The transcription factor recombination signal sequence-binding protein Jkappa (RBP-J) is a key downstream element in the signaling pathway of all four mammalian Notch receptors that are critically involved in the control of embryonic and adult development. RBP-J-deficient mice display complex defects and die around day 9.5 postcoitum. Here, we investigate the function of RBP-J in the development of mesodermal cell lineages by using the OP9 stroma coculture system. RBP-J-deficient embryonic stem (ES) cells gave rise to cardiomyocytes, endothelial cells, and primitive and definitive hematopoietic cells. Thus, RBP-J-mediated signals are not required for generation of these cell types. However, when compared with parental RBP-J-expressing ES cells, cardiomyogenesis derived from RBP-J-deficient ES cells was increased. Repression over the cardiogenic pathway was restored by expressing RBP-J in RBP-J-deficient ES cells. Our data indicate that Notch signaling via RBP-J plays an important role for the correct specification of myocardial cell fates.
