The inhibition and the recovery of brain AChE, buChE, and NTE activities after acute and subacute administration of DFP were studied in the rat. DFP displayed different specificities in inhibiting these enzymes; inhibition was greatest for buChE followed by AChE and NTE. Recovery was most rapid for buChE followed by NTE and AChE. The recovery rates of AChE and buChE following acute and subacute treatment were similar. However, the recovery rate of NTE in subacutely treated rats was significantly faster than that in acutely treated rats. The results suggest that DFP inhibits these three enzymes and the rates of regeneration of these enzymes are significantly different. (c)1989 Academic Press, Inc.

The wave-particle duality of light is a controversial topic in modern physics. In this context, this work highlights the ability of the wave-nature of light on its own to account for the conservation of energy in light-matter interaction. Two simple fundamental properties of light as wave are involved: its period and its power P. The power P depends only on the amplitude of the wave’s electric and magnetic fields (Poynting’s vector), and can easily be measured with a power sensor for visible and infrared lasers. The advantage of such a wave-based approach is that it unveils unexpected effects of light’s power P capable of explaining numerous results published in current scientific literature, of correlating phenomena otherwise considered as disjointed, and of making predictions on ways to employ the electromagnetic (EM) waves which so far are unexplored. In this framework, this work focuses on determining the magnitude of the time interval that, coupled with light’s power P, establishes the energy conserved in the exchange of energy between light and matter. To reach this goal, capacitors were excited with visible and IR lasers at variable average power P. As the result of combining experimental measurements and simulations based on the law of conservation of energy, it was found that the product of the period of the light by its power P fixes the magnitude of the energy conserved in light’s interaction with the capacitors. This finding highlights that the energy exchanged is defined in the time interval equal to the period of the light’s wave. The validity of the finding is shown to hold in light’s interaction with matter in general, e.g. in the photoelectric effect with x-rays, in the transfer of electrons between energy levels in semiconducting interfaces of field effect transistors, in the activation of photosynthetic reactions, and in the generation of action potentials in retinal ganglion cells to enable vision in vertebrates. Finally, the validity of the find

实验目的:比较与反应抑制相关的大脑加工过程对由疼痛的热刺激(PHs)诱发的脑电和由非疼痛的热刺激诱发的脑电(NPHs)调节作用的不同。实验方法:提醒铃声过后,运用CHEPS仪器,给被试呈现疼痛或非疼痛的热刺激,要求被试进行go/nogo任务,即在一半的run中,对疼痛的热刺激进行反应,抑制对非疼痛的热刺激的反应;在另外的一半run中,则相反。这种实验范式能对与go/nogo任务相关的大脑加工在两种体觉刺激下的脑电进行直接的、被试内的比较。实验结果:在nogo条件下,NPHs:在nogo反应的早期,呈现出N120的升高,在后阶段,则呈现出P240b波峰降低和P3波峰升高;PHs:只在后期呈现出与nogo相关的反应,即P350波峰的降低和P3波峰的升高。结论:在NPHs条件下,呈现出与早期nogo相关的波幅的升高,表明大脑对特定的非疼痛刺激的加工。Nogo反应的晚期成分可能表明了反应抑制对疼痛和非疼痛的体觉刺激共同的大脑皮层活动的影响。

Journal of Materials Science & Technology 2017年第12期33卷 1433-1447页

A modelling suite for hydrogen transport during electrochemical permeation, degassing and thermal desorption spectroscopy is presented. The approach is based on Fick＇s diffusion laws, where the initial concentration and diffusion coefficients depend on microstructure and charging conditions. The evolution equations are shown to reduce to classical models for hydrogen diffusion and thermal desorption spectroscopy. The number density of trapping sites is found to be proportional to the mean spacing of each microstructural feature, including dislocations, grain boundaries and various precipitates. The model is validated with several steel grades and polycrystalline nickel for a wide range of processing conditions and microstructures. A systematic study of the factors affecting hydrogen mobility in martensitic steels showed that dislocations control the effective diffusion coefficient of hydrogen. However,they also release hydrogen into the lattice more rapidly than other kind of traps. It is suggested that these effects contribute to the increased susceptibility to hydrogen embrittlement in martensitic and other high-strength steels. These results show that the methodology can be employed as a tool for alloy and process design, and that dislocation kinematics play a crucial role in such design.

Purpose: To compare the clinical and molecular diagnoses of Herpes Simplex Keratitis (HSK). Materials and Methods: Conjunctival swabs (after fluorescein and anaesthetic wash out) and detailed questionnaire data were obtained from 146 participants. Corneal rims and conjunctival epithelial cells were infected with Herpes Simplex Virus (HSV) type 1 or HSV2 and supernatant collected. HSV1;HSV2;Varicella Zoster Virus (VZV) and Adenovirus (ADV) DNA was assessed using two real time Polymerase Chain Reaction (PCR) methods. Results: Of the 146 participants recruited, 54 were clinically diagnosed with typical epithelial lesions and 38 with atypical epithelial lesions, 17 with old inactive HSK and 37 healthy volunteers. HSV1 DNA was detected in 28 (30%) of the 92 participants with clinically suspect HSK. Patients who presented with typical epithelial lesions had a higher positive rate (46%) than those who presented with atypical type lesions (8%), when using primers against the Glycoprotein (Gp) G region of the virus. When the same samples were retested with primers against the Gpb region, the positive rate for the typical and atypical cases increased to 52% and 11% respectively. Antiviral use at the time of sampling reduced the rate of PCR positivity by 20% (p by testing for housekeeping control genes, beta-actin and beta-2 macroglobulin. PCR results from in vitro control investigations of HSV1 and 2 infected corneal rims and conjunctival epithelial cells were 100% positive for infected and 100% negative for uninfected samples when assessed using both PCR methods. Conclusions: Clinical diagnosis of typical HSK is not always confirmed by PCR. Concomitant use of an antiviral reduces levels of PCR positivity. Given this and the findings that other ocular surface pathogens may mimic HSK pat

biliary-colonic fistula is a rare complication after laparoscopic cholecystectomy. We present a case of post-cholecystectomy iatrogenic biliary injury that resulted in a fistula between the common hepatic duct and large bowel. Magnetic resonance cholangiopancreatography provided good visualization of injury even with concurrent normal level of alkaline phosphatase. Radiologic findings and surgical management of this condition are discussed in detail.
