免疫失调与遗传性、特发性和其他情况导致的肺动脉高压（pulmonary arterial hypertension，PAH）中的闭塞性血管重塑有关。循环自身免疫抗体，肺部血管周围淋巴组织以及细胞因子升高都与PAH的病理机制有关，但是这些异常是怎样产生、维持并与疾病的发展联系在一起的仍不明确。为了了解这些问题，研究者将鉴别PAH中肺部特殊的免疫复合物的特异性靶抗原作为出发点，来更好地为未来的免疫调节治疗的应用提供基础。

Classification of interventions in Traditional Chinese Medicine

Journal of Traditional Chinese Medicine 2018年第2期38卷 315-320页

作者： Deng Hongyong Clive E adams Farhad Shokraneh Liang Shanghua Institute of Traditional Chinese Medicine Literature Shanghai University of Traditional Chinese Medicine Cochrane Schizophrenia Group Institute of Mental HealthUniversity of Nottingham

OBJECTIVE: To describe the key systems used for Traditional Chinese Medicine(Tcm) ***: The Tcm classifications used in the International Classification of Diseases-9 Clinical Modification(ICD-9-cm) volume 3, the ICD-10 Procedure Coding System, the International Classification of Health Interventions, and the Medical Subject Headings(Me SH) and Chinese Traditional Medicine and Materia Medica Subject Headings(Tcme SH) thesauruses were compared regarding descriptive terms, structure, and features of Tcm ***: The National Library of Medicine's Me SH thesaurus is ubiquitous. The ICD-9-cm(volume 3),ICD-10 Procedure Coding System, and International Classification of Health Interventions cover insufficient concepts of Tcm, and cannot be used directly as classification systems for Tcm interventions. In contrast, the Tcm contents of the Tcme SH thesaurus are complete, systematic, and detailed, and its hierarchical structure can be used for effective Tcm ***: Tcm classification is very limited and flawed. The Me SH thesaurus helps decrease the detrimental effect of the language barrier. Similarly, the Tcme SH thesaurus can help those without full command of the Mandarin language to access Chinese literature, but the value of searches using Tcme SH could be improved by collaborative working with Information Specialists who are fluent in Mandarin and understand Tcm.

Growth Rates of Giant Miscanthus (Miscanthus×giganteus) and Giant Reed (Arundo donax) in a Low-Input System in Arkansas, USA

引用

American Journal of Plant Sciences 2018年第12期9卷 2371-2384页

作者： Mohan Acharya David M. Burner Amanda J. Ashworth Felix B.

The US Department of Energy is currently building strategies for the expansion of clean and renewable energy sources, and tall, rapidly-growing grasses such as giant miscanthus (Miscanthus × giganteus) and giant reed (Arundo donax) are two of the many of species that could fill this renewable energy niche. The objective was to compare stalk growth components of giant miscanthus and giant reed, in a low-input system (no irrigation and no fertilizer use) in Arkansas, USA. Due to the potential invasiveness of giant reed, our study was conducted on an upland site to minimize escape. Plant height and dry weight per stalk were measured every week for two consecutive growing seasons in 2012 and 2013. Leaf area index (LAI) was measured every two weeks from May to September in 2012. A significant species × day interaction occurred for plant height and dry weight per stalk, due to the relatively greater height and weight of giant reed compared to giant miscanthus after May. Stalk elongation rate was greater for giant reed than giant miscanthus (1.85 and 1.11 cm day-1, respectively). Leaf area index differed between species, giant reed (10.4 m2 m-2) > giant miscanthus (4.4 m2 m-2). We showed that giant reed produced taller, heavier stalks, and had a greater stalk elongation rate, compared to giant miscanthus. For sustainable bioenergy production from giant reed in Arkansas, further studies should be performed to determine ideal number of harvests per year and associated production cost.

Study of Chemical Etching and Chemo-Mechanical Polishing on CdZnTe Nuclear Detectors

Cadmium zinc telluride (CdZnTe) semiconductor has applications in the detection of X-rays and gamma-rays at room temperature without having to use a cooling system. Chemical etching and chemo-mechanical polishing are processes used to smoothen CdZnTe wafer during detector device fabrication. These processes reduce surface damages left after polishing the wafers. In this paper, we compare the effects of etching and chemo-mechanical polishing on CdZnTe nuclear detectors, using a solution of hydrogen bromide in hydrogen peroxide and ethylene glycol mixture. X-ray photoelectron spectroscopy (XPS) was used to monitor TeO2 on the wafer surfaces. Current-voltage and detector-response measurements were made to study the electrical properties and energy resolution. XPS results showed that the chemical etching process resulted in the formation of more TeO2 on the detector surfaces compared to chemo-mechanical polishing. The electrical resistivity of the detector is of the order of 1010 Ω-cm. The chemo-mechanical polishing process increased the leakage current more that chemical etching. For freshly treated surfaces, the etching process is more detrimental to the energy resolution compared to chemo-mechanically polishing.
