High-Urgency Renal Transplantation: Indications and Long-Term Outcomes (2013)

The concept of high-urgency (HU) renal transplantation was introduced in order to offer to patients, who are not able to undergo long-term dialysis treatment, a suitable renal graft in a short period of time, overcoming by this way the obstacle of the prolonged time spent on the waiting list. The goal of this study was to evaluate the patient and graft survivals after HU renal transplantation and compare them to the long-term outcomes of the non-high-urgency renal transplant recipients. The clinical course of 33 HU renal transplant recipients operated on at our center between 1995 and 2010 was retrospectively analyzed. The major indication for the HU renal transplantation was the imminent lack of access for either hemodialysis or peritoneal dialysis (67%). The patient survival of the study population was 67%, 56%, and 56%, whereas the graft survival was 47%, 35% and 35%, at 5, 10, and 15 years, respectively. In the comparison between our study population and the non-HU renal transplant recipients, our study population presented statistically significant (P < 0.05) lower patient survival rates. The HU renal transplant recipients also presented lower graft survival rates, but statistical significance (P < 0.05) was reached only in the 5-year graft survival rate.
Mining generalized term associations: count propagation algorithm (1997)

We present here an approach and algorithm for mining generalized term associations. The problem is to find co-occurrence frequencies of terms, given a collection of documents each with relevant terms, and a taxonomy of terms. We have developed an efficient Count Propagation Algorithm (CPA) targeted for library applications such as Medline. The basis of our approach is that sets of terms (termsets) can be put into a taxonomy. By exploring this taxonomy, CPA propagates the count of termsets to their ancestors in the taxonomy, instead of separately counting individual termset. We found that CPA is more efficient than other algorithms, particularly for counting large termsets. A benchmark on data sets extracted from a Medline database showed that CPA outperforms other known algorithms by up to around 200% (half the computing time) at the cost of less than 20% of additional memory to keep the taxonomy of termsets. We have used discovered knowledge of term associations for the purpose of imp...
Pressure-induced molecular dissociation in iodine at low temperatures (1990)

Abstract Synchrotron x-ray diffraction experiments at low temperatures have revealed that even at 35K the molecular dissociation starts taking place at PS=21.5 and finishes at Pf=26.1GPa. An extrapolation of the phase boundary thus obtained at several temperatures intersects the T=4K line at PS=21.6 and Pf=26.3GPa. This result, inferring the monatomic structure to be realized at P=30GPa and T=4K, leads to a discrepancy against the recent Mössbauer result obtained at the same point in the P-T phase diagram.
Ergebnisse nach Carotis-Rekonstruktion (1979)

In 90 patients a total of 100 reconstructions of the carotid artery had been performed between 1972 and 1977. No patient died from the operation, 3 suffered central nervous complications, and 33 had transitory defects of cranial nerves. These defects were reversible in all but two patients. After an average observation period of 20 months 11 patients had died (6 from cardiac infarction, 2 from stroke, and 3 from unknown reasons). Of the 31 patients with clinical stage II, 24 were without symptoms, 5 had only rare transient ischaemic attacks, and two patients had the same frequency of attacks as preoperatively. Among the 39 stage III patients 35 showed complete or partial regression of symptoms whereas 4 had had repeat strokes. 55 of the 59 corrected stenoses were patent as shown by Doppler ultrasound. In contrast attempts to correct complete internal carotid artery occlusions showed unsatisfactory results.

Bioavailability and biodegradation kinetics protocol for polycyclic aromatic hydrocarbons in soil to enhance bioremediation and to achieve environmentally acceptable endpoints during treatment (1995)

Bioremediation of polluted soil requires a fundamental understanding of biodegradation kinetics and the physicochemical factors that control the rate of biodegradation. A systematic multi-level indigenous microbiota, the transport and diffusivity parameters of soil polycyclic aromatic hydrocarbon (PAH) contaminants and oxygen limitation in freshly PAH spiked and PAH contaminated aged soil matrices. Abiotic adsorption and desorption experiments were conducted to obtain nonlinear isotherms described by the Freundlich isotherm equation. Detailed mathematical models were developed for the four bioreactors and abiotic adsorption and desorption studies together with cumulative oxygen uptake and carbon dioxide evolution data are used to derive the PAH contaminant and oxygen diffusivities in the freshly PAH spiked and PAH contaminated aged soil matrices. Studies included the use of microcosms to qualitatively assess the biodegradation rates and testing with radiolabeled compounds to determine mineralization. Studies with PAH contaminated Reilly Tar soils were undertaken to determine the effect of soil properties on the sequestering process that leads to diminished bioavailability; to evaluate the effect of chemical inducers, surfactants, nutrients, cometabolites, inoculum amendments and moisture content on the rate and extent of PAH biodegradation; and to establish the best attainable environmental endpoints for PAH pollutants in aged soils.
A New Termination for Underground Distribution (1967)

A new principle for stress control on cable terminations has been devised. A tape having a nonlinear voltage-current characteristic is wrapped on the exposed cable end. The resistance of this tape varies with stress in such a manner that the stress along it tends to equalize.
Differences between the Chemical Structures of Duck and Hen Egg‐white Lysozymes (1967)

Histidine‐free duck egg‐white lysozyme III and hen egg‐white lysozyme have similar but not identical structures. some structural differences are reported. The N‐ and C‐terminal sequences are different. The unique histidine and two phenylalanine residues of hen lysozyme are replaced by a leucine and two tyrosine residues, respectively. The more basic character of duck lysozyme III is due to additional arginine residues. Duck egg‐white lysozymes II and III have not entirely identical chemical structures.
Inhibitory Effect of Paprika Seed Extract on the Growth of Film-Forming Yeasts Isolated from Wines (1998)

The inhibitory effects of paprika seed extract (PSE), sulfur dioxide, sorbic acid, and several wine phenols on the growth of film-forming yeasts isolated from wines (six strains of Saccharomyces cerevisiae and one Candida sp. strain) and three standard film-forming yeasts (S. cerevisiae, Candida vini, and C. krusei strains) were investigated.PSE, sulfur dioxide, and sorbic acid had inhibitory activity towards the film-forming yeasts, but no phenols had.The effectiveness of the inhibitory agents varied with the yeats tested.The minimum inhibitory concentrations (MICs) of PSE towards the isolated film-forming yeasts and two of the standard yeasts (S. cerevisiae strain RIFY 3012 C. vini strain RIFY 2024) ranged from 50 to 100μg/ml while toward C. vini and C. krusei they were 50 and 300μg/ml, respectively. On the other hand, the MICs of sulfur dioxide were 100μg/ml towards all the tested strains of S. serevisiae, but those towards Candida differed with the species i.e.23μg/ml toward C. krusei and 300μg/ml towards C. vini. The inhibitory effect of PSE occurred over a broad antimicrobial spectrum when the extract was used in combination with sorbic acid or sulfur dioxide.The results indicate that PSE may be an effective wine preservative through its inhibition of film-forming yeasts.
[Postaggression metabolism following laparotomy and thoracotomy]. (1988)

The purpose of this investigation was to collect data concerning changes in carbohydrate and amino acid metabolism following different surgical operations (thoracotomies, laparotomies). Blood of 20 metabolically healthy adult surgical patients, who had to undergo elective surgery (lobectomies, pneumonectomies, colon resections) was examined preoperatively, immediately postoperatively and from 1.-4.postoperative day. The experimental data during the perioperative phase showed a similar pattern in both groups of patients: We found a significant elevation in the blood glucose level and there was also a rise in plasma cortisol and plasma free fatty acids levels. We found no significant changes of blood lactate, plasma insulin and branched chain amino acids. Simultaneously we found a drop in plasma albumin, pre-albumin and some glucoplastic amino acids (ALA, GLN, THR, PRO). It is concluded that major abdominal and thoracic surgery give rise to a nonspecific stress situation reflected in carbohydrate and amino acid metabolism with the following metabolic symptoms: Raised lipolysis and gluconeogenesis, disturbance of glucose utilisation and obvious peripheral insulin resistance. These perioperative metabolic effects show some similarities to the metabolic situation in diabetes mellitus type 2.

Relationship between transmural potential difference and smooth muscle slow waves and contractility in the rabbit small intestine <i>in vitro</i> (1988)

The relationship between transmural potential difference (PD) and smooth muscle electrical and mechanical activity was investigated in the rabbit ileum in vitro. Transmural PD was monitored using agar salt bridge electrodes connected via calomel half cells to an electrometer. Force displacement transducers recorded predominantly longitudinal smooth muscle activity. Concurrently, predominantly circular muscle activity was recorded at three sites using intraluminal pressure probes. At the same sites, suction electrodes monitored electrical activity of the smooth muscle. In all experiments, fluctuations in transmural PD were temporally linked to smooth muscle mechanical and electrical activity. The frequency of PD oscillations, electrical slow waves, and cyclic pressure changes were identical within each segment. Adrenaline abolished smooth muscle electrical spiking, all mechanical activity, and transmural fluctuations in PD. However, the slow waves were not abolished, though their frequency was increased. Phentolamine but not propranolol reversed the effects of adrenaline, thus slow wave frequency is influenced by alpha-adrenergic stimulation in the rabbit ileum. In conclusion, oscillations in transmural PD are unrelated to the ionic processes associated with the slow wave. However, they are in some way linked to smooth muscle contractile activity, possibly via an intrinsic neural mechanism as observed in the guinea pig.

Are carboxylations involving biotin concerted or nonconcerted? (1980)

Transcarboxylase and propionyl-CoA carboxylase catalyze the elimination of HF from beta-fluoropropionyl-CoA to form acrylyl-CoA. No carboxylation products of fluoropropionyl-CoA could be detected. The elimination proceeds at approximately the same rate as the normal carboxylation reactions. With propionyl-CoA carboxylase, ATP was required (HCO3- was also present) and was hydrolyzed to ADP and Pi. The rate of ADP formation was equal to that of acrylyl-CoA formation. A previous report (Stubbe, J. A., and Abeles, R. H. (1977) J. Biol. Chem. 252, 8338--8340) that acrylyl-CoA formation is faster than ADP formation is in error. With transcarboxylase, oxalacetate was required for acrylyl-CoA formation, and pyruvate was produced. The rate of pyruvate formation was equal to that of acrylyl-CoA formation. We conclude that the ability of the enzyme to catalyze the elimination of HF from beta-fluoropropionyl-CoA indicates that the enzyme can catalyze the abstraction of the substrate alpha-proton without concomitant carboxylation of the substrate. We also conclude that the normal catalytic reaction, therefore, probably involves a carbanion intermediate and does not proceed through a concerted process as has frequently been proposed.
Online Apprenticeship Learning (2021)

In Apprenticeship Learning (AL), we are given a Markov Decision Process (MDP) without access to the cost function. Instead, we observe trajectories sampled by an expert that acts according to some policy. The goal is to find a policy that matches the expert's performance on some predefined set of cost functions. We introduce an online variant of AL (Online Apprenticeship Learning; OAL), where the agent is expected to perform comparably to the expert while interacting with the environment. We show that the OAL problem can be effectively solved by combining two mirror descent based no-regret algorithms: one for policy optimization and another for learning the worst case cost. By employing optimistic exploration, we derive a convergent algorithm with $O(\sqrt{K})$ regret, where $K$ is the number of interactions with the MDP, and an additional linear error term that depends on the amount of expert trajectories available. Importantly, our algorithm avoids the need to solve an MDP at each iteration, making it more practical compared to prior AL methods. Finally, we implement a deep variant of our algorithm which shares some similarities to GAIL \cite{ho2016generative}, but where the discriminator is replaced with the costs learned by the OAL problem. Our simulations suggest that OAL performs well in high dimensional control problems.
Comparative analysis of G2 arrest after irradiation with 75 keV carbon-ion beams and 137Cs γ-rays in a human lymphoblastoid cell line (2003)

Heavy-ion beams are more effective than gamma-rays in causing G2 arrest. In this study, we investigated the expression of Wee1 and Cdc2 protein levels in order to analyze the G2 arrest caused by carbon-ion beam irradiation. Human lymphoblastoid TK6 cells were exposed to a 75 keV carbon-ion beam or 137Cs gamma-rays. Although the levels of Wee1 and Cdc2 protein were increased after exposure to either beam, Wee1 protein levels were influenced more by carbon-ion beam irradiation than by gamma-rays. To the contrary, Cdc2 protein levels were increased more by gamma-rays than by carbon-ion beams. These findings suggest that the G2 arrest produced by heavy-ion beams, such as the carbon-ion irradiation used in this study, might be associated with the overexpression of the Wee1 protein and of Cdc2 phosphorylation regulated by Wee1. Together, these events may act to prolong the length of G2 arrest.
A Review of Radiologic Imaging in Patients with Androgen Insensitivity (2013)

A Review of Radiologic Imaging in Patients with Androgen Insensitivity Androgen insensitivity (AIS) is a disorder of sex development that results from mutations in the androgen receptor. In complete AIS, patients are genetically XY, but phenotypically female and frequently present with primary amenorrhea in the teenage years. In partial AIS, patients are also genetically XY, but the phenotype varies based on the amount of activity of the androgen receptor and commonly present with ambiguous genitalia.
Complement receptor type 1 (CR1) deficiency on neutrophils in myelodysplastic syndrome (1994)

We present a patient with myelodysplastic syndromes (MDS) whose neutrophils exhibited defective expression of complement receptor type 1 (CR1). A 73-year-old man was admitted with an evolution of MDS from RA into RAEBT according to the FAB classification of MDS. The neutrophil alkaline phosphatase (NAP) score was zero. The surface expression of membrane effector molecules on neutrophils was determined by indirect immunofluorescence using flow cytometry and monoclonal antibodies. The expression of CR1 on neutrophils as identified by staining with CD35 was defective in the patient, and the expression of other complement receptors (CR3 and CR4), Fc receptors and adhesion molecules was normal. CR1 deficiency and defective NAP score on neutrophils in the patient might account for impairment of common storage pool, presumably novel intracellular secretory vesicles.
Large-scale Taxonomy Induction Using Entity and Word Embeddings (2021)

Taxonomies are an important ingredient of knowledge organization, and serve as a backbone for more sophisticated knowledge representations in intelligent systems, such as formal ontologies. However, building taxonomies manually is a costly endeavor, and hence, automatic methods for taxonomy induction are a good alternative to build large-scale taxonomies. In this paper, we propose TIEmb, an approach for automatic unsupervised class subsumption axiom extraction from knowledge bases using entity and text embeddings. We apply the approach on the WebIsA database, a database of subsumption relations extracted from the large portion of the World Wide Web, to extract class hierarchies in the Person and Place domain.

A Comparative Study on Non-Autoregressive Modelings for Speech-to-Text Generation (2021)

Non-autoregressive (NAR) models simultaneously generate multiple outputs in a sequence, which significantly reduces the inference speed at the cost of accuracy drop compared to autoregressive baselines. Showing great potential for real-time applications, an increasing number of NAR models have been explored in different fields to mitigate the performance gap against AR models. In this work, we conduct a comparative study of various NAR modeling methods for end-to-end automatic speech recognition (ASR). Experiments are performed in the state-of-the-art setting using ESPnet. The results on various tasks provide interesting findings for developing an understanding of NAR ASR, such as the accuracy-speed trade-off and robustness against long-form utterances. We also show that the techniques can be combined for further improvement and applied to NAR end-to-end speech translation. All the implementations are publicly available to encourage further research in NAR speech processing.
Good-Turing estimation of the number of operating sensors: a large deviations analysis (2004)

We have proposed an estimator for the number of operating sensors in a wireless sensor network based on the Good-Turing non-parametric estimator of the missing mass (Budianu and Tong, Proc. Asilomar Conf. on Sig., Systems and Computers, 2003). We now investigate the performance of this estimator using the theory of large deviations. We determine the asymptotic behavior of the large deviations exponent as the ratio n/N between the number of collected samples n and the number of operating sensors N decreases to zero. The simulations reveal that the confidence intervals obtained using the large deviations formula are upper bounds for the actual performance of the estimator. Together with the asymptotic behavior of the exponent, this suggests the surprising fact that if the scaling law n=f(N) is used for the number of samples, then reliable estimation can be done if n grows at least as fast as /spl radic/N. Separately, it is shown that, if lim/sub N/spl rarr//spl infin//(n//spl radic/N)=0, the estimator cannot be used.
