Privacy Data Envelope: Concept and implementation (2011)

In this paper, we present a privacy control mechanism called PDE (Privacy Data Envelope) allowing users to protect their privacy sensitive content travelling over social and communication networks. Our solution is based on privacy policies expressed by the user and associated with his content. This approach makes use of a decentralized architecture carried out through a PDE feature that has to be added to the existing application access tools like email clients and web browsers. A prototype has been developed to embody the PDE paradigm and to illustrate a scenario where such envelopes cross the boundaries of enterprise social networks and other communications tools. Preliminary performance evaluations were done helping the understanding of the PDE plug-in behaviors and computation overhead.
Factors influencing the herbicidal activity of Nep1, a fungal protein that induces the hypersensitive response in<i>Centaurea maculosa</i> (2000)

The fungal protein Nep1, produced by Fusarium oxysporum f. sp. erythroxyli in liquid culture, caused extensive necrosis to Centaurea maculosa when water solutions of Nep1 (5 µg ml−1) and an organosilicone surfactant (1,1,1,3,5,5,5-heptamethyltrisiloxanyl propyl-methoxy-poly[ethylene oxide]) were applied as foliar sprays. Nep1 did not cause necrosis when applied with a nonionic surfactant or organosilicone surfactant plus unrefined corn oil. Plant age, protein concentration, organosilicone surfactant concentration, and the presence of a dew period influenced the amount of necrosis caused by Nep1. The addition of an 18-h dew period after treatment resulted in an increase of 10% or more in foliar necrosis at the 0.313 and 1.25 µg ml−1 (0.40 and 1.62 g ai ha−1) Nep1 concentrations. Increasing the spray volume from 129 ml m−2 (1,291.3 L ha−1) to 516 ml m−2 (5,165.2 L ha−1) more than doubled the amount of foliar necrosis caused by the 0.313 µg ml−1 (0.40 g ai ha−1 vs. 1.62 g ai ha−1) Nep1 concentration. A maximum necrosis rating of 95% was reached by 1.25 µg ml−1 Nep1 applied at 516 ml m−2 (6.46 g ai ha−1) followed by an 18-h dew period. Nep1 (6.46 g ai ha−1) remained active when coapplied to Centaurea maculosa with the herbicides 2,4-D or glyphosate (0.13 to 2.58 kg ai ha−1), causing foliar necrosis prior to the herbicides killing Centaurea maculosa. An increase in the organosilicone surfactant concentration from 1 to 2 ml ai L−1 was required to achieve levels of Nep1-induced necrosis on Centaurea maculosa acclimated to direct sun comparable to levels achieved on greenhouse-grown plants. Repeated application of Nep1 (6.48 g ai ha−1) 3 wk after an initial treatment (6.48 g ai ha−1) prevented the recovery of acclimated Centaurea maculosa. Greater damage was caused to acclimated Centaurea maculosa when Nep1 was applied near the middle of the day (80% necrosis at 10:00 A.M. and 85% necrosis at 2:00 P.M.) compared to early or late in the day (25% necrosis at 6:00 A.M. and 10% necrosis at 6:00 P.M.).
An equation of state for polar and non-polar substances and mixtures (1984)

Simple cubic equations of state, such as the Redlich–Kwong–Soave (RKS) equation, have been used successfully to describe the behaviour of weakly polar substances for both single- and two-phase properties and equilibria.In this paper we point out how important it is for an equation of state for a substance to fit the entire vapour-pressure curve from the triple point to the critical point. We show how even a simple equation that fits the entire vapour-pressure curve for a substance can quite accurately model a very wide range of compounds and their mixtures. Our new equation is a simple modification of the RKS equation. For each substance it represents accurately the vapour-pressure curve using two constants which are obtained by regression from vapour-pressure data covering the whole range of temperatures from the triple point to the critical point.We show here that the new equation can represent accurately the vapour pressures, enthalpies, heats of vaporisation and vapour densities of the individual substances, but like most cubic equations it is inaccurate for liquid densities. With binary interaction parameters the equation also describes two-phase equilibria for a wide range of mixtures of both strongly and weakly polar substances with an accuracy similar to that of the RKS equation for mixtures of weakly polar substances.We give constants for 12 substances: H2, CH4, HCl, CS2, C2H6, n-C5H12, n-C8H18, H2O, CH3OH, CO2, C6H6 and anthracene (C14H10), chosen to illustrate the range of substances to which the new equation applies. We compare calculated results with experimental data for six binary systems (CH4+ C2H6, CH4+ n-C8H18, CH3OH + H2O, CO2+ H2O and n-C5H12+ H2O), selected to cover the widest range of types of mixtures. The results demonstrate that the new equation of state describes the behaviour of all these binary systems with an accuracy similar to that of the RKS equation for weakly polar systems. For several of these mixtures this is the first equation of state able to describe their behaviour.
Interleukin-6 induces androgen responsiveness in prostate cancer cells through up-regulation of androgen receptor expression. (2001)

Interleukin-6 (IL-6) induces prostate cancer (CaP) cell proliferation in vitro. Several lines of evidence suggest that IL-6 may promote CaP progression through induction of an androgen response. In this work, we explored whether IL-6 induces androgen responsiveness through modulation of androgen receptor (AR) expression. We found that in the absence of androgen, IL-6 increased prostate-specific antigen (PSA) mRNA levels and activated several androgen-responsive promoters, but not the non-androgen responsive promoters in LNCaP cells. Bicalutamide, an antiandrogen, abolished the IL-6 effect and IL-6 could not activate the PSA and murine mammary tumor virus reporters in AR-negative DU-145 and PC3 cells. These data indicate the IL-6 induces an androgen response in CaP cells through the AR. Pretreatment of LNCaP cells with SB202190, PD98059, or tyrphostin AG879 [p38 mitogen-activated protein kinase (MAPK), MAP/extracellular signal-regulated protein kinase kinase 1/2, and ErbB2 MAPK inhibitors, respectively) but not wortmannin (PI3-kinase inhibitor) blocked IL-6-mediated induction of the PSA promoter, which demonstrates that IL-6 activity is dependent on a MAPK pathway. Finally, IL-6 activated the AR gene promoter, resulting in increased AR mRNA and protein levels in LNCaP cells. These results demonstrate that IL-6 induces AR expression and are the first report of cytokine-mediated induction of the AR promoter. Taken together, our results suggest that IL-6 induces AR activity through both increasing AR gene expression and activating the AR in the absence of androgen in CaP cells. These results provide a mechanism through which IL-6 may contribute to the development of androgen-independent CaP.
The diffusion of gases through metals (1935)

Abstract Since the original discovery by Graham in 1866 that hydrogen could diffuse through platinum, the phenomena of diffusion of gases through metals have been the subject of many investigations. Various empirical equations have been proposed to represent the effect of temperature and pressure on the rate of diffusion, and in 1904 Richardson, Nicol, and Parnell arrived at an equation from theoretical considerations which was in good agreement with their own measurements of the diffusion of hydrogen through platinum. This equation, generally known as Richard­ son’s equation, may be written D = k/d. P½ T½e─b/T, (1) where D is the rate of diffusion per unit area of surface, P is the gas pressure, T the temperature, d the thickness of the metal, and b a constant for the gas-metal system. The equation applies to conditions in which gas is maintained at a pressure P on one side of the metal, whilst a vacuum is maintained on the other side. If instead of a vacuum a pressure P1, where P1 &lt; P, exists, the term √P in the equation is replaced by (√P ─ √P1).
Molecular characterization of cis-prenyltransferase complexes in guayule (Parthenium argentatum) (2017)

Natural Rubber (NR) is a biopolymer with an irreplaceable role in the fields of medicine, manufacturing, and transport. Despite its necessity, the Brazilian Rubber Tree (Hevea brasiliensis) remains virtually the sole source of NR. As the majority of NR plantations are in Southeast Asia, its production is threatened by climate and disease. While NR supply remains insecure, biochemical studies have identified two essential proteins: cis-prenyltransferases (CPTs) and cis-prenyltransferase Binding Proteins (CBPs). With recent studies elucidating the biochemical properties of plant CPTs and CBPs, a potential mechanism for NR biosynthesis has been proposed. As the bulk of NR research has so far focused on two phylogenetically close relatives, lettuce and dandelion, further evidence is required from a more genetically distant plant species. This research is focused on guayule (Parthenium argentatum, Asteraceae family) – an alternative NR-producing plant long-diverged from lettuce and dandelion. CBP and CPT homologs, PaCBP and PaCPT1-3, were identified through publicly available transcriptomics databases and various biochemical assays were undertaken. In vivo split-ubiquitin yeast two hybrid and co-immunoprecipitation assays have indicated strong levels of interaction between the PaCPTs and PaCBP. Interestingly, our findings also show that guayule CPTs, together with guayule’s CBP, are responsible for the production of dolichol-like polymers in vitro rather than NR. This was shown by using harvested microsomes from yeast that expressed heterologous guayule CBP and CPTs in a biochemical assay. The biochemical assay was performed using [14C]-radiolabeled isopentenyl pyrophosphate as substrate. The polymer sizes were determined through reverse-phase thin layer chromatography. Another method used to determine the function of CPT and CBP was to rescue the lethal phenotype of dolichol synthase-deficient yeast by co-expressing CPT and CBP. Furthermore, phylogenetic and expression analyses of PaCPT1-3 revealed PaCPT3 as both likely involved in NR biosynthesis and highly expressed throughout the plant. PaCPT3 may therefore prove to be suitable for future NR studies and biotechnological applications. Taken together, our data provide further evidence of a NR biosynthetic mechanism that is conserved across the Asteraceae family, while also increasing guayule’s viability as both a production alternative and model for the study of NR.
Efficient Construction of an Inverted Minimal H1 Promoter Driven siRNA Expression Cassette: Facilitation of Promoter and siRNA Sequence Exchange (2007)

The unique design of this construct allows for the efficient exchange of siRNA sequences by the directional cloning of short oligonucleotides via asymmetric restriction sites. This provides a convenient way to test the functionality of different siRNA sequences. Delivery of the siRNA cassette by retroviral transduction suggests that a single copy of the siRNA expression cassette efficiently knocks down gene expression at the protein level. We note that this vector system can potentially be used to generate a random siRNA library. The flexibility of the ligase chain reaction suggests that additional control elements can easily be introduced into this siRNA expression cassette.
Rectification of thermal fluctuations in a chaotic cavity heat engine (2012)

We investigate the rectification of thermal fluctuations in a mesoscopic on-chip heat engine. The engine consists of a hot chaotic cavity capacitively coupled to a cold cavity which rectifies the excess noise and generates a directed current. The fluctuation-induced directed current depends on the energy asymmetry of the transmissions of the contacts of the cold cavity to the leads and is proportional to the temperature difference. We discuss the channel dependence of the maximal power output of the heat engine and its efficiency.
Doxepin or diazepam for anxious and anxious-depressed outpatients? (1978)

A six-week double blind comparison of doxepin and diazepam in the treatment of 61 anxious outpatients showed few drug differences. Diazepam treated patients improved significantly more early in the trial, according to a few measures. They also had significantly fewer complaints of drowsiness. By six weeks, the medicines appeared roughly equal in efficacy. Practically no support was found for the position that doxepin may be more beneficial for anxious-depressive syndromes. In all patients, and also within the anxious-depressive subgroup, there were small mean differences on many criteria favoring doxepin at six weeks, but none reached significance. The doxepin group gained significantly more weight. Possible biasing influences were present requiring that the results be interpreted with particular caution.
Evolution and Prospects for Intracranial Pharmacotherapy for Refractory Epilepsies: The Subdural Hybrid Neuroprosthesis (2010)

Intracranial pharmacotherapy is a novel strategy to treat drug refractory, localization-related epilepsies not amenable to resective surgery. The common feature of the method is the use of some type of antiepileptic drug (AED) delivery device placed inside the cranium to prevent or stop focal seizures. This distinguishes it from other nonconventional methods, such as intrathecal pharmacotherapy, electrical neurostimulation, gene therapy, cell transplantation, and local cooling. AED-delivery systems comprise drug releasing polymers and neuroprosthetic devices that can deliver AEDs into the brain via intraparenchymal, ventricular, or transmeningeal routes. One such device is the subdural Hybrid Neuroprosthesis (HNP), designed to deliver AEDs, such as muscimol, into the subdural/subarachnoid space overlaying neocortical epileptogenic zones, with electrophysiological feedback from the treated tissue. The idea of intracranial pharmacotherapy and HNP treatment for epilepsy originated from multiple sources, including the advent of implanted medical devices, safety data for intracranial electrodes and catheters, evidence for the seizure-controlling efficacy of intracerebral AEDs, and further understanding of the pathophysiology of focal epilepsy. Successful introduction of intracranial pharmacotherapy into clinical practice depends on how the intertwined scientific, engineering, clinical, neurosurgical and regulatory challenges will be met to produce an effective and commercially viable device.
Providing reusability in distributed object control systems (2002)

Large scale, distributed industrial and scientific systems share many technical problems in the implementation of their control systems. Up to the present control system developers have had little opportunity of reusing software developed in one control system in the implementation of another. With the advent of standards in distributed object technology, it is now feasible to reuse control objects in a deterministic manner across control systems. Such objects could be user-written components, (encapsulating) supervisory components or commercially available software such as expert systems or user interfaces. The CERN CICERO project aims to identify and implement the main building blocks of a generic control information system based on the distributed object techniques of CORBA. CICERO is producing an integrating environment, Cortex, into which distributed user control objects will ultimately be 'plugged and played' and a supporting information system for the configuration and management of Cortex has been designed to be sufficiently generic in nature to allow its reuse by any future control system used at CERN and potentially by medium to large scale industrial control systems such as power systems, satellite control and telecommunications network management. This paper describes how an object-oriented approach to designing and implementing Cortex will provide a reusable set of solutions to delivering large distributed control systems.
Hyperparathyroid bone disease in chronic renal failure. (1985)

Much has been learnt over the past 80 years of the pathogenesis and management of hyperparathyroid bone disease in uraemia. Clinically it has changed from a rare disorder of childhood and adolescence to a common and difficult problem in patients maintained on dialysis programmes. Whereas effective treatments are now available for hyperparathyroid bone disease, these are not curative and there is clearly much more work to be done before a full understanding of its pathogenesis, and the best methods of treatment and prevention, can be reached.
Fiber Optic Optrodes For Chemical Sensing (2005)

There has been a remarkable development of chemical fiberoptic sensors in recent years. The first chemical fiberoptic sensor, which was a sensor for detecting ammonia, was described in 19761. Since then, investigations have been made of numerous parameters, from pH2 to gases3; from antibodies4 to metallic ions5. This particularly intense interest is completely justified, both because the detection of chemical parameters is extremely important in many industrial and chemical processes, in environmental control and in the biomedical field; and also because chemical fiberoptic sensors offer considerable advantages compared to traditional sensors.
Model-Based Closed-Loop Glucose Control in Type 1 Diabetes: The DiaCon Experience (2013)

This study suggests that our novel MPC algorithm can safely and effectively control glucose overnight, also when CL control is initiated during hyperglycemia.
A Critical Review of Electroporation as A Plasmid Delivery System in Mouse Skeletal Muscle (2019)

The gene delivery to skeletal muscles is a promising strategy for the treatment of both muscular disorders (by silencing or overexpression of specific gene) and systemic secretion of therapeutic proteins. The use of a physical method like electroporation with plate or needle electrodes facilitates long-lasting gene silencing in situ. It has been reported that electroporation enhances the expression of the naked DNA gene in the skeletal muscle up to 100 times and decreases the changeability of the intramuscular expression. Coelectransfer of reporter genes such as green fluorescent protein (GFP), luciferase or beta-galactosidase allows the observation of correctly performed silencing in the muscles. Appropriate selection of plasmid injection volume and concentration, as well as electrotransfer parameters, such as the voltage, the length and the number of electrical pulses do not cause long-term damage to myocytes. In this review, we summarized the electroporation methodology as well as the procedure of electrotransfer to the gastrocnemius, tibialis, soleus and foot muscles and compare their advantages and disadvantages.
A laboratory study of the dependence of elastic wave velocities on pore scale fluid distribution (1990)

Laboratory data have been collected during a continuous imbibition/drainage experiment that show a clear dependence of elastic wave velocities on the details of the pore scale distribution of water and air in a sandstone. Compressional wave velocity (V p ) was measured at a frequency of 1 MHz; shear wave velocity (Vs) was measured at a frequency of 600 kHz. During the experiment, V p showed little variation with the level of water saturation (Sw) during increasing S w through imbibition until S w = 0.80, at which point V p increased dramatically. When S w was decreased, pronounced saturation‐induced hysteresis was observed in the region 03 < S w < 0.9, with V p measured during drainage greater than V p measured during imbibition. Similar results were obtained for V s versus S w , with V s during drainage greater that V s during imbibition in the saturation range S w > 0.4. As a simple model, we consider the imbibition process as producing a partially saturated state in all pores; i.e. all pores contain both air and water. The drainage process, in contrast, favors the existence of either air‐filled or water‐filled pores. As elastic wave velocities are very sensitive to the saturation state in the smaller, “crack‐like” pores, these variations in fluid distribution cause related variations in velocities.
[The monosaccharide composition of the glycocalyx in Mollicutes and phylogenetically related bacteria in the genus Bacillus]. (2000)

A number of monosaccharides composing the glycocalix carbohydrates of some Mollicutes (Mycoplasma pneumoniae FH, M. hominis PG21, M. fermentans PG18, Acholeplasma laidlawii PG8, A. laidlawii var. granulum st. 118) and phylogenetically related bacteria from the genus Bacillus (Bacillus cereus 89, B. cereus DM423, B. subtilis 1/2, B. licheniformis 31, B. licheniformis 49) were detected using plant lectins of definite carbohydrate specificity labelled by colloid gold. The structure of extracellular glycopolymers of microorganisms was discussed concerning their role in the adhesion process and their specializations in colonization of the appropriate organs and tissues of macroorganisms as well as the action of probiotics on the basis of bacteria from the genus Bacillus. It was marked, that the mollicute cells typically interacted with all vegetable lectins tested while bacilli studied bind certain lectins only. The surface carbohydrates prevailing in monosaccharides from tested one for superficial structures of Bacillus pathogenic strains were: sialic acid, beta-D-galactose and alpha-N-acetyl-D-galactosamine, while L-fucose and alpha-D-glucose were observed in insignificant quantity or were absent. The nonpathogenic Bacillus strains being a basis of biopreparations were distinguished by the insignificant amount of sialic acid and other monosaccharides in the composition of carbohydrates of their glycocalix. Thus, as a result of research it was confirmed, that the superficial glycopolymers of Mollicutes and some related bacilli were alike as to presence of some monosaccharides that depended on taxonomic position of microorganisms and their biological activity.
