Medical and Surgical Therapies for Pain Associated with Endometriosis (2001)

Endometriosis is a common condition for which a number of treatments have been proposed. Medical treatments are based on the hormonal responsiveness of endometriosis implants. These therapies include progestins (with or without estrogens), androgens, and gonadotropin-releasing hormone (GnRH) analogs. Surgical treatments may include hysterectomy with oophorectomy or organ-sparing surgery involving ablation or resection of visible lesions of endometriosis and restoration of pelvic anatomy. There are no studies that directly compare the effectiveness or adverse effects of medical therapy and surgical therapy. Studies on medical therapy compare different treatments with placebo or with other active treatments. Hormone-based therapies for endometriosis show 80%-100% effectiveness in relief of pelvic pain over a 6-month course of therapy. Serious adverse outcomes after medical therapy are unusual. Studies on surgical therapy are largely anecdotal, with noncomparative reports on a variety of surgical methods. A few comparative surgical studies have been reported. Because of the noncomparative nature of many of the surgical studies, the use of combinations of surgical procedures and techniques in the reported studies, and the reporting of results from surgeons with an unusually high level of technical skill, the gynecological practitioner has little basis in the literature for assessing the optimum surgical approach. Surgical complications are believed to be underreported and may be related to how aggressive a surgical procedure is undertaken.
Extremely thermostable L(+)‐lactate dehydrogenase from thermotoga maritima: Cloning, characterization, and crystallization of the recombinant enzyme in its tetrameric and octameric state (1996)

L(+)-lactate dehydrogenase (LDH; E.C.1.1.1.27) from the hyperthermophilic bacterium Thermotoga maritima has been shown to represent the most stable LDH isolated so far (Wrba A, Jaenicke R, Huber R, Stetter KO, 1990, Eur J Biochem 188:195-201). In order to obtain the enzyme in amounts sufficient for physical characterization, and to analyze the molecular basis of its intrinsic stability, the gene was cloned and expressed functionally in Escherichia coli. Growth of the cells and purification of the enzyme were performed aerobically at 26 degrees C, i.e., ca. 60 degrees below the optimal growth temperature of Thermotoga. Two enzyme species with LDH activity were purified to homogeneity. Crystals of the enzyme obtained at 4 degrees C show satisfactory diffraction suitable for X-ray analysis up to a resolution of 2.8 A. As shown by gel-permeation chromatography, chemical crosslinking, light scattering, analytical ultracentrifugation, and electron microscopy, the two LDH species represent homotetramers and homooctamers (i.e., dimers of tetramers), with a common subunit molecular mass of 35 kDa. The spectroscopic characteristics (UV absorption, fluorescence emission, near- and far-UV CD) of the two species are indistinguishable. The calculated alpha-helix content is 45%, in accordance with the result of homology modeling. Compared to the tetrameric enzyme, the octamer exhibits reduced specific activity, whereas KM is unalatered. The extreme intrinsic stability of the protein is reflected by its unaltered catalytic activity over 4 h at 85 degrees C; irreversible thermal denaturation becomes significant at approximately 95 degrees C. The anomalous resistance toward chemical denaturation using guanidinium chloride and urea confirms this observation. Both the high optimal temperature and the pH optimum of the catalytic activity correspond to the growth conditions of T. maritima in its natural habitat.
On Second Generation Hypermedia Systems (2020)

In this paper we claim that the navigational and structural tools currently available on the Internet are not sufficient to fully exploit the tremendous power of the largest information and communication ressource mankind has ever had. We contend that current hypermedia systems and its most prominent specimen WWW do not have enough functionality to provide the power that is needed. We explain important features that are absent, claim that "second generation" hypermedia systems incorporating such features are essential and mention a first such second generation hypermedia system called Hyper-G, which is just becoming available and is starting to be used for a wide variety of applications.
Interleukin-16, produced by synovial fibroblasts, mediates chemoattraction for CD4+ T lymphocytes in rheumatoid arthritis (1998)

The massive infiltration of synovium with CD4+ T cells during the course of rheumatoid arthritis (RA) implies the expression of chemoattractant factors by resident synovial cells. Therefore, we analyzed the expression of IL-16, a potent chemoattractant for CD4+ T cells, to account for the accumulation of CD4+ T cells in RA. Indeed, IL-16 was found to be significantly elevated in synovial fluid (SF) from patients with RA as compared to non-RA arthritis (p < 0.001), osteoarthritis (p < 0.001) and controls (p < 0.001). Chemotaxis studies showed IL-16 to contribute to the strong chemotactic activities of RA-SF. In situ hybridization (ISH) revealed IL-16 mRNA-expressing cells located within the lining layer of rheumatoid synovial tissue. In the sublining area, only scattered IL-16 transcript-positive cells could be detected, mainly adjacent to blood vessels. By a double-labeling technique, combining ISH for IL-16 mRNA and immunohistochemistry for CD68, synovial fibroblast-like, CD68-negative cells were identified as a major source of IL-16 mRNA within RA synovium. This study demonstrates that synovial fibroblasts produce IL-16 in RA and thus mediate chemoattraction of CD4+ cells into synovial tissue.
N*N square-element ultrasound phased-array applicator: simulated temperature distributions associated with directly synthesized heating patterns (1990)

Computer simulations to demonstrate the possibility of heating small tumors by appropriately driving the electronic control circuitry of an n*n square-element ultrasonic phased array are conducted. The synthesis method consists of simultaneously focusing the ultrasonic beam at different points uniformly distributed along the tumor periphery and, hence, involves no scanning. It is demonstrated that by combining the multiple focusing feature with a new field phasing concept, typical undesired hot spots can be eliminated. The tissue thermal response to this heating modality is investigated by iteratively solving the three-dimensional steady-state bioheat equation. Temperature distributions associated with different directly synthesized power deposition patterns are simulated and discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Enantioselective pharmacokinetics of 10-hydroxycarbazepine after oral administration of oxcarbazepine to healthy Chinese subjects (1999)

The marked differences in serum levels and urinary excretion between the two enantiomers of 10-hydroxycarbazepine are likely to be related primarily to stereoselective presystemic metabolic keto-reduction of the prochiral carbonyl group of the oxcarbazepine molecule.
MonetDB/X100: Hyper-Pipelining Query Execution (2005)

Database systems tend to achieve only low IPC (instructions-per-cycle) efficiency on modern CPUs in compute-intensive application areas like decision support, OLAP and multimedia retrieval. This paper starts with an in-depth investigation to the reason why this happens, focusing on the TPC-H benchmark. Our analysis of various relational systems and MonetDB leads us to a new set of guidelines for designing a query processor. The second part of the paper describes the architecture of our new X100 query engine for the MonetDB system that follows these guidelines. On the surface, it resembles a classical Volcano-style engine, but the crucial difference to base all execution on the concept of vector processing makes it highly CPU efficient. We evaluate the power of MonetDB/X100 on the 100GB version of TPC-H, showing its raw execution power to be between one and two orders of magnitude higher than previous technology. 1
A randomized study of high-dose cytarabine in induction in acute myeloid leukemia [see comments] (1996)

High-dose cytarabine (ara-c) may overcome cytarabine resistance in leukemic blasts. It has been used as a successful salvage and in postremission therapy but not as initial induction treatment. Patients aged 15 to 60 years, presenting with newly diagnosed acute myeloid leukemia (AML) were randomized to receive either high-dose cytarabine, 3 g/m2 12 hourly on days 1, 3, 5, and 7 for 8 doses, daunorubicin 50 mg/m2 days 1 to 3, etoposide 75 mg/m2 days 1 to 7, (HIDAC-3-7) or standard dose cytarabine 100 mg/m2 continuous intravenous infusion for 7 days with daunorubicin and etoposide at the same dose and schedule as above (7-3-7). Patients could receive a second or third induction course if complete remission (CR) was not achieved. All patients received the same postinduction consolidation therapy (5-2-5) for 2 courses. Eligible patients had no prior chemotherapy or myelodysplastic disease. Patients have been followed for a median of 4.5 years. Of 301 patients treated, complete response (CR) was achieved in 71% with HIDAC-3-7 and 74% with 7-3-7. For patients in CR, the estimated median remission duration was 45 months with HIDAC-3-7 and 12 months with 7-3-7 (P = .0005 univariate analysis, P = .0004 multivariate analysis). The estimated percentage of patients relapse free 5 years after achieving a CR was 49% on HIDAC-3-7 and 24% on 7-3-7. Patients in CR tended to survive longer with HIDAC-3-7 but there were no overall survival differences between the two arms. HIDAC-3-7 was associated with significantly more toxicity in induction with more leukopenia, thrombocytopenia, nausea, and vomiting and eye toxicity (all P < .001) but a similar incidence of severe central nervous system and cerebellar toxicity compared to 7-3-7. The consolidation treatment was the same in both arms but caused significantly more leukopenia and thrombocytopenia in patients previously treated with HIDAC-3-7 induction (P < .0001). We conclude that a dose-effect exists for cytarabine in AML and that HIDAC-3-7 prolongs remission duration and disease-free survival and is tolerable when used as initial induction therapy in patients with de novo AML.

Early sodium intake and later blood pressure in preterm infants. (1988)

The relation between early salt intake and later hypertension is debated. As part of a larger feeding study, 347 preterm infants were randomly assigned to receive early diets differing grossly in sodium content. Feeding a high sodium preterm formula in the neonatal period did not influence arterial blood pressure at 18 months (corrected) age.
A study of ovarian cancer biomarker amplification using ultrasound for early stage detection (2013)

The application of serum biomarker to ovarian tumors for early stage detection and clinical diagnosis is a rapidly expanding research area. The problem with conventional markers is that they are often released too late or at too low a level to be detected in time to trigger effective treatment. Ultrasound has been used to influence bio-effects in living cells, but there is only one reported case of the use of ultrasound to enhance the release of a biomarker (Carcinoembryonic antigen CEA). In this study we report the use of ultrasound to enhance the release of a combination of ovarian cancer biomarkers (CA125 and CA19-9) to help in the diagnosis of ovarian cancer at an early stage. The results indicated that after 5 min sonication at a frequency of 1 MHz and intensity of 0.3 W cm(-2), the CA125 and CA19-9 levels were increased by 2.02 and 4.21-fold respectively. These findings suggest that ultrasonic treatment can be used to enhance the release of serum biomarkers from ovarian tumors.
Phosphoinositide 3-kinase signalling pathways (2001)

Phosphoinositide 3-kinases (PI3Ks) phosphorylate the 3'-OH position of the inositol ring of inositol phospholipids, producing three lipid products: PtdIns(3)P, PtdIns(3,4)P(2) and PtdIns(3,4,5)P(3). These lipids bind to the pleckstrin homology (PH) domains of proteins and control the activity and subcellular localisation of a diverse array of signal transduction molecules. Three major classes of signalling molecule are regulated by binding of D-3 phosphoinositides to PH domains: guanine-nucleotide-exchange proteins for Rho family GTPases, the TEC family tyrosine kinases such as BTK and ITK in B and T lymphocytes, respectively, and the AGC superfamily of serine/threonine protein kinases. These molecules are activated by a variety of extracellular stimuli and have been implicated in a wide range of cellular processes, including cell cycle progression, cell growth, cell motility, cell adhesion and cell survival.
Autoimmunity and Diabetes (1999)

The face of immune-mediated (type 1) diabetes is changing. No longer considered a disease confined to childhood, the incidence rate in Western countries is clearly rising and affecting younger children. Such a secular trend can only be explained on the basis of increased contacts with adverse environmental factors acting on a background of complex genetics. Multiple defects in immunological tolerance to "self' predispose to immune-mediated (type 1) diabetes. Initiation of immune responses involves the cytokine rich natural killer T cells. Such cells appear deficient in both humans and the rodent models of the disease. Furthermore, the regulatory abilities of T cells in general seem to be compromised. Effector mechanisms probably are dominated by cell-mediated beta cell destruction through apoptosis induction. Surprisingly, the essential antigen-presenting cells in the autoimmune processes involved appear to be B lymphocytes. The improved understanding of the beta cell autoantigens involved has led to better disease prediction. The long prodromal phase now readily identifiable through autoantibodies is spawning hopes of disease prevention, notably through antigen-based interventions or diabetes "vaccines."
Substrate Specificities of Three Members of the Human UDP-N-Acetyl-α-d-galactosamine:Polypeptide N-Acetylgalactosaminyltransferase Family, GalNAc-T1, -T2, and -T3 (1997)

Mucin-type O-glycosylation is initiated by UDP-N-acetylgalactosamine:polypeptide N-acetylgalactosaminyltransferases (GalNAc-transferases). The role each GalNAc-transferase plays in O-glycosylation is unclear. In this report we characterized the specificity and kinetic properties of three purified recombinant GalNAc-transferases. GalNAc-T1, -T2, and -T3 were expressed as soluble proteins in insect cells and purified to near homogeneity. The enzymes have distinct but partly overlapping specificities with short peptide acceptor substrates. Peptides specifically utilized by GalNAc-T2 or -T3, or preferentially by GalNAc-T1 were identified. GalNAc-T1 and -T3 showed strict donor substrate specificities for UDP-GalNAc, whereas GalNAc-T2 also utilized UDP-Gal with one peptide acceptor substrate. Glycosylation of peptides based on MUC1 tandem repeat showed that three of five potential sites in the tandem repeat were glycosylated by all three enzymes when one or five repeat peptides were analyzed. However, analysis of enzyme kinetics by capillary electrophoresis and mass spectrometry demonstrated that the three enzymes react at different rates with individual sites in the MUC1 repeat. The results demonstrate that individual GalNAc-transferases have distinct activities and the initiation of O-glycosylation in a cell is regulated by a repertoire of GalNAc-transferases.
Surveillance for lower airway pathogens in mechanically ventilated patients by metabolomic analysis of exhaled breath: a case-control study (2015)

Breath volatile analysis is able to classify breath profiles of patients with and without significant pathogen load in the lower respiratory tract. If validated in independent cohorts, these findings could lead to development of rapid non-invasive point-of-care surveillance systems and diagnostics for lower respiratory tract infection in the intensive care unit.
Neuroprotective effects ofTriticum aestivumL. against β‐Amyloid‐induced cell death and memory impairments (2009)

beta-Amyloid (A beta) is a key component of senile plaques, neuropathological hallmarks of Alzheimer's disease (AD) and has been reported to induce cell death via oxidative stress. This study investigated the protective effects of Triticum aestivum L. (TAL) on A beta-induced apoptosis in SH-SY5Y cells and cognitive dysfunctions in Sprague-Dawley (SD) rats. Cells treated with A beta exhibited decreased viability and apoptotic features, such as DNA fragmentation, alterations in mitochondria and an increased Bax/Bcl-2 ratio, which were attenuated by TAL extract (TALE) pretreatment. To elucidate the neuroprotective mechanisms of TALE, the study examined A beta-induced oxidative stress and cellular defense. TALE pretreatment suppressed A beta-increased intracellular accumulation of reactive oxygen species (ROS) via up-regulation of glutathione, an essential endogenous antioxidant. To further verify the effect of TALE on memory impairments, A beta or scopolamine was injected in SD rats and a water maze task conducted as a spatial memory test. A beta or scopolamine treatment increased the time taken to find the platform during training trials, which was decreased by TALE pretreatment. Furthermore, one of the active components of TALE, total dietary fiber also effectively inhibited A beta-induced cytotoxicity and scopolamine-caused memory deficits. These results suggest that TALE may have preventive and/or therapeutic potential in the management of AD.

The complete genome of an individual by massively parallel DNA sequencing (2008)

The association of genetic variation with disease and drug response, and improvements in nucleic acid technologies, have given great optimism for the impact of 'genomic medicine'. However, the formidable size of the diploid human genome, approximately 6 gigabases, has prevented the routine application of sequencing methods to deciphering complete individual human genomes. To realize the full potential of genomics for human health, this limitation must be overcome. Here we report the DNA sequence of a diploid genome of a single individual, James D. Watson, sequenced to 7.4-fold redundancy in two months using massively parallel sequencing in picolitre-size reaction vessels. This sequence was completed in two months at approximately one-hundredth of the cost of traditional capillary electrophoresis methods. Comparison of the sequence to the reference genome led to the identification of 3.3 million single nucleotide polymorphisms, of which 10,654 cause amino-acid substitution within the coding sequence. In addition, we accurately identified small-scale (2-40,000 base pair (bp)) insertion and deletion polymorphism as well as copy number variation resulting in the large-scale gain and loss of chromosomal segments ranging from 26,000 to 1.5 million base pairs. Overall, these results agree well with recent results of sequencing of a single individual by traditional methods. However, in addition to being faster and significantly less expensive, this sequencing technology avoids the arbitrary loss of genomic sequences inherent in random shotgun sequencing by bacterial cloning because it amplifies DNA in a cell-free system. As a result, we further demonstrate the acquisition of novel human sequence, including novel genes not previously identified by traditional genomic sequencing. This is the first genome sequenced by next-generation technologies. Therefore it is a pilot for the future challenges of 'personalized genome sequencing'.
Automated Text Summarization in SUMMARIST (1997)

SUMMARIST is an attempt to create a robust automated text summarization system, based on the equation: summarization = topic identification interpretation generation. Each of these stages contains several independent modules, many of them trained on large corpora of text. We describe the systems architecture and provide details of some of its modules.
Mitochondrial localization of a phosphoprotein that rapidly accumulates in adrenal cortex cells exposed to adrenocorticotropic hormone or to cAMP (1989)

We have reported previously that a phosphoprotein, ib, is present in adrenal cortex, corpus luteum, and Leydig cells stimulated with either tissue-specific peptide hormone or with cAMP. The accumulation of protein ib in each of these cell types has been found to parallel the stimulation of steroid synthesis with respect to both time course and stimulant dose response. Thus, protein ib is a potential mediator in the acute stimulation of steroidogenesis by peptide hormone or cyclic AMP. A second protein, pb, the unphosphorylated form of ib, is synthesized constitutively in unstimulated but not stimulated cells and is not converted post-translationally to ib upon stimulation. Using two-dimensional gel electrophoresis of subcellular fractions isolated from rat adrenal cortex cells labeled with [35S] methionine, we have determined the intracellular localization of proteins p and i. We demonstrate that proteins ib and pb are localized predominantly in the mitochondria and are tightly associated with that organelle. We also find that inhibition of mitochondrial protein synthesis by chloramphenicol affects neither the accumulation of these proteins nor the stimulation of steroidogenesis. Thus, protein pb and its phosphorylated counterpart, ib, are synthesized in the cytosol and transported to the mitochondria, the site of the rate-limiting step in steroid hormone biosynthesis.
