The role of glutathione biosynthesis in heavy metal resistance in the fission yeast Schizosaccharomyces pombe (1994)

Plants and the fission yeast Schizosaccharomyces pombe synthesize small cadmium-binding peptides, called phytochelatins, in response to cadmium. Derived from glutathione (GSH: λ-Glu-Cys-Gly), they have the general structure (λ-Glu-Cys)nGly, where n is 2–11. In order to study the biosynthesis of phytochelatins, we used the mutagen N-methyl-N′-nitro-N nitrosoguanidine (MNNG) to select mutants with a lowered GSH content. GSH-deficient mutants show a Cd-sensitive phenotype, whereas resistance to Cu is only slightly influenced. These Cd-sensitive mutants contain 2–15% of the wild-type GSH level. For three mutants a lowered activity of λ-glutamylcysteine synthetase was measured. One of the mutants was transformed to Cd-resistance and the complementing fragment was analyzed further. The complementing fragment hybridized with chromosome III. In the transformants, GSH content was restored up to wild-type levels, whereas the activity of λ-glutamylcysteine synthetase was significantly increased compared with the wild-type. Possible mechanisms for Cd-resistance in the transformants are discussed.
New Alkali Doped Pillared Carbon Materials Designed to Achieve Practical Reversible Hydrogen Storage for Transportation (2004)

We propose a new generation of materials to maximize reversible H2 storage at room temperature and modest pressures (<20 bars). We test these materials using grand canonical Monte Carlo simulations with a first-principles-derived force field and find that the Li pillared graphene sheet system can take up 6.5 mass% of H2 (a density of 62.9 kg/m(3) at 20 bars and room temperature. This satisfies the DOE (Department of Energy) target of hydrogen-storage materials for transportation. We also suggest ways to synthesize these systems. In addition we show that Li-doped pillared single-wall nanotubes can lead to a hydrogen-storage capacity of 6.0 mass% and 61.7 kg/m(3) at 50 bars and room temperature storage, which is close to the DOE target.
Bipartite graph for topic extraction (2015)

This article presents a bipartite graph propagation method to be applied to different tasks in the machine learning unsupervised domain, such as topic extraction and clustering. We introduce the objectives and hypothesis that motivate the use of graph based method, and we give the intuition of the proposed Bipartite Graph Propagation Algorithm. The contribution of this study is the development of new method that allows the use of heuristic knowledge to discover topics in textual data easier than it is possible in the traditional mathematical formalism based on Latent Dirichlet Allocation (LDA). Initial experiments demonstrate that our Bipartite Graph Propagation algorithm return good results in a static context (offline algorithm). Now, our research is focusing on big amount of data and dynamic context (online algorithm).
The effect of compounds which degrade hydrogen peroxide on the enumeration of heat-stressed cells of <i>Salmonella senftenberg</i> (1978)

Greater than 90% of heat-stressed cells of Salmonella senftenberg failed to grow on trypticase soy agar. Adding to this medium compounds which are capable of degrading hydrogen peroxide allowed growth of the heat-injured cells. These compounds did not stimulate growth of heated cells of Streptococcus faecinin. an organism which does not possess catalase.
Analysis and design of a zero current switched quasi-resonant converter with synchronous rectification for low output voltage applications (2003)

An analysis of a zero-current-switched quasi-resonant power converter (ZCS-QRC) including the effects of a finite magnetizing inductance is presented. The resulting topology seems to be very useful for the implementation of synchronous rectification techniques in a nondissipative way, allowing high-frequency operation. A design guideline based on the design procedure developed is given. Simulation and experimental results show very good performance in terms of high efficiency for low output voltage and high output current applications. Experimental results for two different output conditions (5 V/20 A and 3.3 V/20 A) are presented. Both converters work at a nominal switching frequency of 250 kHz, achieving a very good trade-off between efficiency and size.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Extract of <i>Pogostemon cablin</i> Possesses Potent Anticancer Activity against Colorectal Cancer Cells In Vitro and In Vivo (2020)

<i>Pogostemon cablin</i> (PCa), an herb used in traditional Chinese medicine, is routinely used in the amelioration of different types of gastrointestinal discomfort. However, the mechanisms underlying the cancer suppression activity of PCa in colorectal cancer (CRC) cells have yet to be clarified. The aim of this study was to investigate the anticancer effects of PCa, specifically the induction of apoptosis in CRC cells. The growth inhibition curve of CRC cells following exposure to PCa was detected by an MTT assay. Moreover, PCa combined with 5-FU revealed a synergic effect of decreased cell viability. PCa inhibited cell proliferation and induced cell cycle arrest at the G<sub>0</sub>/G<sub>1</sub> phase and cell apoptosis through regulation of associated protein expression. An in vivo study showed that PCa suppressed the growth of CRC via induction of cell apoptosis with no significant change in body weight or organ histology. Our results demonstrated that PCa inhibits the growth of CRC cells and induces apoptosis in vitro and in vivo, which suggests the potential applicability of PCa as an anticancer agent.
The Effect of Rumor Spreading in Reputation Systems for Mobile Ad-hoc Networks (2003)

Mobile ad-hoc networks rely on the cooperation of nodes for routing and forwarding. For individual nodes there are however several advantages resulting from noncooperation, the most obvious being power saving. Nodes that act selfishly or even maliciously pose a threat to availability in mobile ad-hoc networks. Sev-eral approaches have been proposed to detect nonco-operative nodes. In this paper, we investigate the effect of using rumors with respect to the detection time of misbehaved nodes as well as the robustness of the rep-utation system against wrong accusations. We propose a Bayesian approach for reputation representation, up-dates, and view integration. We also present a mech-anism to detect and exclude potential lies. The simu-lation results indicate that by using this Bayesian ap-proach, the reputation system is robust against slander while still benefitting from the speed-up in detection time provided by the use of rumors. 1
Gene therapy for pancreatic cancer (2011)

Pancreatic cancer was one of common malignant tumors of the digestive tract, early diagnosis of which was difficult and surgical resection rate was low. The prognosis was poor, and its incidence increased year by year. Conventional treatment of pancreatic cancer includes surgery, radiotherapy and chemotherapy, but 90％ of the patients had lost the surgical opportunity when they see a doctor, and not sensitive to radiotherapy and chemotherapy. Relative to these traditional treatments, gene therapy is an innovative approach for the treatment of pancreatic cancer and had attracted wide attention in recent years. Many gene therapy drugs for pancreatic cancer had now entered Ⅰ / Ⅱ clinical trials. The gene therapy techniques for pancreatic cancer included antisense gene therapy, suicide gene therapy, immune gene therapy, and oncolytic virus therapy. In this article, we reviewed recent advances in gene therapy for pancreatic cancer.

Genetic programming for edge detection using blocks to extract features (2012)

Single pixels can be directly used to construct low-level edge detectors but these detectors are not good for suppressing noise and some texture. In general, features based on a small area are used to suppress noise and texture. However, there is very little guidance in the literature on how to select the area size. In this paper, we employ Genetic Programming (GP) to evolve edge detectors via automatically searching for features based on flexible blocks rather than dividing a fixed window into small areas based on different directions. Experimental results for natural images show that using blocks to extract features obtains better performance than using single pixels only to construct detectors, and that GP can successfully choose the block size for extracting features.
Growth of <i>Ferrobacillus ferrooxidans</i> on Organic Matter (1969)

Following a brief adaptation period to glucose, Ferrobacillus ferrooxidans was grown on glucose, mannitol, several other sugars, and a few amino acids in the absence of an oxidizable iron source. Prolonged growth on an organic substrate free from iron rendered the organism obligately organotrophic. The growth rate of the bacterium was greater in heterotrophic culture; the doubling time was approximately 4.5 hr on glucose. The bacterium retained its acidophilic properties during adaptation and growth on glucose and would not grow in neutral or slightly alkaline media. Addition of p -aminobenzoic acid was necessary for abundant growth of the cells on glucose. Of the eight strains of Fe ++ -oxidizing bacteria studied, only two strains grew on glucose in a nondialyzed system. The results of manometric studies are discussed with regard to metabolic efficiency of organic matter in this organism.

We report an experimental observation of an increased ${\mathrm{T}}_{\mathrm{c}}$ up to 159 K with temperature cycling in YBaCuO and YBaCuO:F samples. This increase in ${\mathrm{T}}_{\mathrm{c}}$ is tentatively associated with a structural phase transition or ordering occurring at a well defined temperature close to 239 K. We have used the presence of this phase ordering to achieve improved-${\mathrm{T}}_{\mathrm{c}}$ material and tentatively attribute it to a two-dimensional to one-dimensional structural change.
A role-based conflict resolution method for a collaborative system (2004)

Conflict resolution is one of the most important problems that must be solved in building a collaborative system. In many CSCW (computer-supported-cooperative work) applications or systems, roles were granted in the design and application of these systems. Consequently, we may infer that "without roles, there would be no collaboration". Based on the success of RBAC, we found that role-based methods are very useful in building collaborative systems. However, there is little research on conflict resolution based on roles. This paper, briefly introduces an object model for collaborative systems OMCS and a multimedia co-authoring system MCAS, and mainly discusses the role management and a role-based conflict avoidance and resolution method in the system MCAS. It emphasizes the importance of roles in conflict avoidance and resolution. In the last section, it summarizes the paper and draws a conclusion is drawn that a role-based method can help greatly to resolve conflicts in collaborative systems.
The OSI network management model- capacity and performance management (2008)

With the rapid growth of large enterprise networks, capacity and performance management issues are becoming increasingly important to both business organizations and the telecommunication industry. Capacity and performance management techniques and methods provide guidance on how to plan, justify and manage network resources. Inappropriate planning for capacity and performance may lead to wasted resources resulting in unnecessary cost, or lack of resources resulting in poor network performance or even the unavailability of IT services. Moreover, it is not uncommon for networks to be equipped with devices from different vendors which potentially add to complexity. Resource management may be assisted by using a network management framework. The OSI Network Management Model (NMM) is the standard model and provides a conceptual framework for organizing a diverse range of network resources. This paper is an analysis of the OSI NMM to evaluate its use within large enterprise networks focusing upon capacity and performance management.

The performed study revealed that SLC34A2 gene exhibited the most distinct change in expression and may become a molecular marker of papillary thyroid cancer.
Delayed Retention of New Word-Forms Is Better in Children than Adults Regardless of Language Ability: A Factorial Two-Way Study (2012)

Poor nonword repetition in SLI appears to reflect inadequate encoding of phonological information, rather than problems retaining encoded information. Furthermore, the nonword learning task is consistent with the notion of a sensitive period in language learning: Children show better retention over a delay for new phonological sequences than adults, regardless of overall level of language ability.

Civic Republicanism and Green Political Theory (2009)

Republicanism and in particular the civic republican tradition is not often one that one finds in discusions and debates within green political theory. It is interesting to note the relative lack of engagement between republican political theory and green political theory, unlike for example the research one can find on the relationship between green politics/political theory and liberalism, socialism and feminism. This is remarkable, given, as I hope to establish in this paper, the large areas of overlap between both, and in particular the compatibility of republican ideas and positions with key priciples and objectives of green theory, paricularly in relation to active citizenship, the centrality of recognising vulnerability and a commitment to liberty (as non-domination) and pluralism as key components of the transition to a more sustainable society.
Congestion control of Poisson distributed ABR applications in ATM networks using neural network (2003)

The standard flow control of available bit rate (ABR) services, as proposed by the ATM Forum, is the rate-based congestion control scheme. This congestion control scheme uses the resource management (RM) cell to carry feedback information. In this paper, a neural approach ABR congestion control scheme that uses an artificial neural network to monitor the queue length in each switch, and then a suitable ER value is calculated based on the queue status. This algorithm is called the neural indicates explicit rate (NIER) scheme. This paper also presents an extensive comparison study of the proposed switching scheme and three other schemes. A standard heavily loaded "parking-lot" network is used to test the effectiveness and efficiency of these schemes. Meanwhile, the on-off ABR applications or Poisson distributed ABR services are used. The simulation results show that the proposed algorithm gives good performance.
Liquid Chromatography with Post-Column Reagent Addition of Ammonia in Methanol Coupled to Negative Ion Electrospray Ionization Tandem Mass Spectrometry for Determination of Phenoxyacid Herbicides and their Degradation Products in Surface Water (2010)

A new liquid chromatography (LC)-negative ion electrospray ionization (ESI(-))-tandem mass spectrometry (MS/MS) method with post-column addition of ammonia in methanol has been developed for the analysis of acid herbicides: 2,4-dichlorophenoxy acetic acid, 4-chloro-o-tolyloxyacetic acid, 2-(2-methyl-4-chlorophenoxy)butyric acid, mecoprop, dichlorprop, 4-(2,4-dichlorophenoxy) butyric acid, 2,4,5-trichlorophenoxy propionic acid, dicamba and bromoxynil, along with their degradation products: 4-chloro-2-methylphenol, 2,4-dichlorophenol, 2,4,5-trichlorophenol and 3,5-dibromo-4-hydroxybenzoic acid. The samples were extracted from the surface water matrix using solid-phase extraction (SPE) with a polymeric sorbent and analyzed with LC ESI(-) with selected reaction monitoring (SRM) using a three-point confirmation approach. Chromatography was performed on a Zorbax Eclipse XDB-C18 (50 x 4.6 mm i.d., 1.8 mum) with a gradient elution using water-methanol with 2 mM ammonium acetate mobile phase at a flow rate of 0.15 mL/min. Ammonia in methanol (0.8 M) was added post-column at a flow rate of 0.05 mL/min to enhance ionization of the degradation products in the MS source. One SRM transition was used for quantitative analysis while the second SRM along with the ratio of SRM1/SRM2 within the relative standard deviation determined by standards for each individual pesticide and retention time match were used for confirmation. The standard deviation of ratio of SRM1/SRM2 obtained from standards run on the day of analysis for different phenoxyacid herbicides ranged from 3.9 to 18.5%. Limits of detection (LOD) were between 1 and 15 ng L(-1) and method detection limits (MDL) with strict criteria requiring <25% deviation of peak area from best-fit line for both SRM1 and SRM2 ranged from 5 to 10 ng L(-1) for acid ingredients (except dicamba at 30 ng L(-1)) and from 2 to 30 ng L(-1) for degradation products. The SPE-LC-ESI(-) MS/MS method permitted low nanogram-per-liter determination of pesticides and degradation products for surface water samples.
Characterization of the cyclic short-time variation of indoor power-line channels response (2005)

Indoor power-line channels response exhibits a time-varying behaviour with a twofold nature. The first one is the well-known long-term variation caused by the connection and disconnection of electrical devices. The second one is a short-time variation, synchronous to the mains, whose origin is the dependence of the impedance presented by electrical devices on the mains voltage (Canete, FJ et al., 2005). The purpose of this paper is to assess the importance of this latter aspect in actual channels. To this end, a measurement procedure able to extract these short-time variations is described at first. Afterwards, a statistical analysis of the results obtained from a measurement campaign performed at different scenarios is given. Specifically, the delay spread, the peak excursion and the rate of change of the frequency response in the band from 1 MHz to 20 MHz are presented and discussed.
Self-help for ailing structures (2003)

The notion of structures that mend themselves sounds more like an idea from science fiction than a topic for scientific investigation. Not so, say the researchers who are drawing inspiration from biological healing processes to create new composites with a built-in tool kit. This approach to materials maintenance is attracting considerable interest from the aerospace industry, given the potential value for self-repairing airplanes and spacecraft. But first, the self-help concept needs to be proven outside of the laboratory in tests that mimic likely wear and tear scenarios in the real world. It is relatively easy to illustrate the concept of a self-repairing system using familiar examples. Remember what happened when you tripped on a sidewalk as a child and grazed your knee or the last time you cut your finger. Almost at once, blood rushes to the site of the injury, leaking out where the skin has been punctured. But wait a while, and the blood oozing slowly from superficial cuts and scratches begins to clot. The clot formation slows, the bleeding stops, and, after a while, a scab forms over the damaged surface. Eventually, the scab falls off revealing a new patch of skin. Your body has healed itself, having responded instantaneously and subconsciously to the initial injury.
Prostatic ductal system in rats: Regional variation in stromal organization (1996)

The rat prostate is composed of a complex system of branching ducts which terminate proximally at the urethra. It has been recognized that epithelial cells lining the ducts respond differently to androgen in various regions of the ducts, with responses ranging from proliferation to apoptosis, but the cellular mechanisms underlying these effects are unclear. Interaction between prostatic stroma and epithelium is essential to normal prostate growth and development, and the prostatic stroma is thought to be the first site of androgen action. Therefore we have examined the organization and distribution of stromal cell types along the rat prostatic ductal system. Using immunohistochemical techniques, we observed abundant fibrous tissue surrounding the distal region of the ducts, with a sparse, discontinuous smooth muscle layer. The intermediate region was surrounded by a continuous layers of smooth muscle one to two cells thick, which increased to greater than four layers thick at the proximal region. Fibrous tissue was located in interductal spaces and occasionally interspersed within the muscle layers in both regions. These observations indicate that regional variations in the distribution of stromal cell types exist and suggest that their corresponding secretory products could be responsible for the various effects of androgen on the epithelium in the rat prostatic ductal system.
