Ultrasensitive detection of Ebola matrix protein in a memristor mode

We demonstrate the direct biosensing of the Ebola VP40 matrix protein, using a memristor mode of a liquid-integrated nanodevice, based on a large array of honeycomb-shaped silicon nanowires. To shed more light on the principle of biodetection using memristors, we engineered the opening of the current-minima voltage gap VG by involving the third gap-control electrode （gate voltage, VG） into the system. The primary role of VG is to mimic the presence of the charged species of the desired sign at the active area of the sensor. We further showed the advantages of biodetection with an initially opened controlled gap （Vc~ ~a 0）, which allows the detection of the lowest concentrations of the biomolecules carrying arbitrary positive or negative charges; this feature was not present in previous configurations. We compared the bio-memristor performance, in terms of its detection range and sensitivity, to that of the already-known field-effect transistor （FET） mode by operating the same device. To our knowledge, this is the first demonstration of Ebola matrix protein detection using a nanoscaled electrical sensor.

Destruction of hexafluoroethane in a dielectric-packed bed plasma reactor

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2010年第7期11卷 538-544页

作者： D. H. kim Y. S. MOK S. B. LEE S. M. SHIn Department of Chemical & Biological Engineering Research Institute of Advanced Technology Jeju National University Environmental Business Unit Samsung Engineering Co. Ltd. Hwasung Gyeonggido Korea

The destruction of hexafluoroethane (C2F6), also known as R-116, was investigated in a nonthermal plasma reactor packed with dielectric pellets. The effects of the feed gas composition and the input power on the destruction of C2F6 were examined. The feed gas composition was varied by changing the oxygen content, the argon content and the initial C2F6 concentration. An increased input power led to increased C2F6 destruction as a result of promoting the electron-molecule collisions to dissociate C2F6 molecules. The addition of argon to the feed gas greatly improved the C2F6 destruction by reducing the energy losses due to vibrational excitation and dissociation of n2 molecules, while the increases in the oxygen content and the initial C2F6 concentration decreased the destruction efficiency. The byproducts including CO2, CO, COF2, CF4, SiF4, nO2, and n2O were identified, and the destruction mechanisms were elucidated, referring to these compounds. The most abundant byproduct was found to be carbonyl fluoride (COF2), indicating that it serves as an important medium to convert C2F6 into CO2. The energy requirement for the C2F6 destruction was in the range of 8.2–45.3 MJ/g, depending on the initial concentration.

手术截断小鼠尾末端可诱发长期性的痛觉过敏和吗啡镇痛效应变化。这种长期性的变化可能是由于中枢神经系统的神经可塑性变化引起的(从脊髓背角到皮层)。在截尾5周后,小鼠后肢和余下的尾端出现痛敏反应。低剂量吗啡可诱发热板的易化反应。这些可塑性变化能延长至5周,因此小鼠的截尾模型可以用于研究截肢后的中枢性长期性的可塑性变化。

Energy and environmental issues presently attract a great deal of scientific attention. Recently, two-dimensional MXenes and MXene-based nanomaterials have attracted increasing interest because of their unique properties (e.g., remarkable safety, a very large interlayer spacing, environmental flexibility, a large surface area, and thermal conductivity). In 2011, multilayered MXenes (Ti3C2Tx, a new family of two-dimensional (2D) materials) produced by etching an A layer from a MAX phase of Ti3AlC2, were first described by researchers at Drexel University. The term “MXene” was coined to distinguish this new family of 2D materials from graphene, and applies to both the original MAX phases and MXenes fabricated from them. We present a comprehensive review of recent studies on energy and environmental applications of MXene and MXene-based nanomaterials, including energy conversion and storage, adsorption, membrane, photocatalysis, and antimicrobial. Future research needs are discussed briefly with current challenges that must be overcome before we completely understand the extraordinary properties of MXene and MXene-based nanomaterials.

Development of tenofovir disoproxil fumarate resistance after complete viral suppression in a patient with treatment-na?ve chronic hepatitis B: A case report and review of the literature

引用

World Journal of Gastroenterology 2018年第17期24卷 1919-1924页

作者： Woo Hee Cho Hyun Jae Lee Ki Bae Bang Seok Bae kim Il Han Song Department of Internal Medicine Dankook University College of MedicineCheonan 31116South Korea

Tenofovir disoproxil fumarate(TDF) is a potent nucleo-tide analogue that is recommended as first-line therapy for patients with chronic hepatitis B. The results of a longitudinal study of TDF treatment demonstrated no development of resistance. We observed one treatment-na?ve chronic hepatitis B(CHB) patient who developed TDF resistance after complete viral suppression during long-term TDF treatment. A 37-year-old HBe Ag-positive man received TDF 300 mg/d for 43 mo. The hepatitis B virus(HBV) DnA titer was 8 log_(10) copies/m L at baseline and became undetectable at 16 mo after treatment. However, the HBV DnA titer rebounded to 7.5 log_(10) copies/m L at 43 mo after treatment. We performed full sequencing to find mutation sites associated with virologic breakthrough. The results showed 9 mutation sites, most of which had not been well-known as mutation sites. We changed the therapy from tenofovir to entecavir with a regimen of 0.5 mg once daily. After 4 mo, the HBV DnA titer decreased to 267 copies/m L, and the liver enzyme levels were normalized.
