Central serotonergic and noradrenergic receptors in functional dyspepsia

World Journal of Gastroenterology 2006年第17期12卷 2681-2687页

Functional dyspepsia is a symptom complex characterised by upper abdominal discomfort or pain, early satiety, motor abnormalities, abdominal bloating and nausea in the absence of organic disease. The central nervous system plays an important role in the conducting and processing of visceral signals. Alterations in brain processing of pain, perception and affective responses may be key factors in the pathogenesis of functional dyspepsia. Central serotonergic and noradrenergic receptor systems are involved in the processing of motor, sensory and secretory activities of the gastrointestinal tract. Visceral hypersensitivity is currently regarded as the mechanism responsible for both motor alterations and abdominal pain in functional dyspepsia. some studies suggest that there are alterations in central serotonergic and noradrenergic systems which may partially explain some of the symptoms of functional dyspepsia. Alterations in the autonomic nervous system may be implicated in the motor abnormalities and increases in visceral sensitivity in these patients. Noradrenaline is the main neurotransmitter in the sympathetic nervous system and again alterations in the functioning of this system may lead to changes in motor function. Functional dyspepsia causes considerable burden on the patient and society. The pathophysiology of functional dyspepsia is not fully understood but alterations in central processing by the serotonergic and noradrenergic systems may provide plausible explanations for at least some of the symptoms and offer possible treatment targets for the future.

Preparation of electroless Ni-P composite coatings containing nano-scattered alumina in presence of polymeric surfactant

引用

Progress in Natural science:Materials International 2012年第4期22卷 318-325页

作者： s.Afroukhteh C.Dehghanian M.Emamy University of Tehran College of EngineeringSchool of Metallurgical and Materials EngineeringTehranIran

Ni-P electroless coating was applied on low carbon steel with the incorporation of different amounts of nano Al2O3 powder (ranging from 3g/l to 30 g/l) in electroless bath. Corrosion properties and microstructures of the coating were studied. The dispersion stability of alumina colloidal particles stabilized by polymeric (non-ionic) surfactants in an electroless bath was also investigated. The surface morphology and the relevant structure were evaluated by scanning electron microscopy (sEM) and X-ray diffraction (XRD). Corrosion behavior of the coated steel was evaluated by electrochemical impedance spectroscopy (EIs) and polarization techniques. The results showed that increasing alumina concentration not only changed the surface morphology, but also promoted the corrosion resistance. Addition of surfactants has an indirect effect on the amount of the incorporated particles. Meanwhile, in the presence of surfactant, corrosion resistance of Ni-P coating containing even a small quantity of alumina was improved since a stabilized bath was obtained.

PREPARATION AND ANALYsIs OF Ni-P-Zn ELECTROLEss DEPOsITION FROM ALKALI BATH

Electroless Ni-P-Zn alloys deposited from alkali bath were investigated in this paper. The deposition bath contained nickel sulfate, zinc chloride and hypophosp hate. The process parameters, such as temperature, pH and zinc salt concentratio n were presented and discussed. The microstructure of the coatings was studied b y XRD and sEM. The cathode glowing discharge characters of Ni-P-Zn depositions w ere studied with luminous Neon lamps. Electrodes deposited by electroless Ni-P a lloys were apt to sputter during luminous working hours. Electroless Ni-P-Zn dep ositions improved the discharge characters of the electrodes. With the concentra tion of zinc in the deposition rising to 4wt%, electrode sputter was largely res trained. The thickness of the deposition also influenced the discharge character s of the electrode. To avoid electrode sputter, the concentration of zinc has to rise with the thickness of the depositions.

Two loop low temperature corrections to electron self energy

Chinese Physics C 2011年第7期35卷 608-611页

作者： Mahnaz Q. Haseeb samina s. Masood Department of Physics COMSATS Institute of Information Technology Islamabad Pakistan Department of Physics University of Houston Clear Lake Houston TX 77058

We recalculate the two loop corrections in the background heat bath using real time formalism. The procedure of the integrations of loop momenta with dependence on finite temperature before the momenta without it has been followed. We determine the mass and wavefunction renormalization constants in the low temperature limit of QED, for the first time with this preferred order of integrations. The correction to electron mass and spinors in this limit is important in the early universe at the time of primordial nucleosynthesis as well as in astrophysics.

A Multiple Model Approach to Modeling Based on LPF Algorithm

引用

Journal of systems Engineering and Electronics 2001年第3期12卷 64-70页

作者： Li, N. Li, s. Xi, Y. Institute of Automation Shanghai Jiaotong University Shanghai 200030 China

Input-output data fitting methods are often used for unknown-structure nonlinear system modeling. Based on model-on-demand tactics, a multiple model approach to modeling for nonlinear systems is presented. The basic idea is to find out, from vast historical system input-output data sets, some data sets matching with the current working point, then to develop a local model using Local Polynomial Fitting (LPF) algorithm. With the change of working points, multiple local models are built, which realize the exact modeling for the global system. By comparing to other methods, the simulation results show good performance for its simple, effective and reliable estimation.
