| 1 | 黄土中的碳酸盐矿物特征与化学风化显示文摘从中国黄土沉积中提取古环境演化信息已取得重大进展,然而,如何有效区分黄土中原生和次生碳酸盐,进而用于追踪粉尘的来源和揭示风化成壤的强度,仍有很大困难。为了辨别黄土中不同成因的碳酸盐矿物,本文从黄土高原西部靖远和古浪剖面中选取2个典型古土壤和黄土样品(S0和L1),分为5个粒级(〈4μm,4~8μm,8~16μm,16~32μm和32~63μm),进行了热重分析(TGA)和X射线衍射测试(XRD)。结果表明:1)黄土中的碳酸盐主要由方解石和白云石组成,原生方解石和白云石在黄土中的含量比古土壤中含量高,并偏富集于粗颗粒组分;2)次生方解石在占土壤中的含量比黄土中高,并显著富集于细颗粒组分。在黄土和古土壤全样和分粒级样品中,TGA和XRD方法分别测出的Carb-B/Carb-A和(方解石+白云石)/方解石比值变化一致,有望成为反映黄土风化成壤强度的新代用指标。 | 梁莲姬 孙有斌 Christiaan J.

| 2 | New insights in the treatment of acromioclavicular separation显示文摘A direct force on the superior aspect of the shoulder may cause acromioclavicular(AC) dislocation or separation. Severe dislocations can lead to chronic impairment, especially in the athlete and high-demand manual laborer. The dislocation is classified according to Rockwood. Types Ⅰ?and Ⅱ are treated nonoperatively, while types Ⅳ, Ⅴ and Ⅵ are generally treated operatively. Controversy exists regarding the optimal treatment of type Ⅲ dislocations in the high-demand patient. Recent evidence suggests that these should be treated nonoperatively initially. Classic surgical techniques were associated with high complication rates, including recurrent dislocations and hardware breakage. In recent years, many new techniques have been introduced in order to improve the outcomes. Arthroscopic reconstruction or repair techniques have promising short-term results. This article aims to provide a current concepts review on the treatment of AC dislocations with emphasis on recent developments. | Christiaan J A van Bergen Annelies F van Bemmel Tjarco D W Alta Arthur van Noort | 2017 | World Journal of Orthopedics2017,8,12: | 12 |
| 3 | 用于甲烷芳构化的Mo/HZSM-5催化剂的活化(英文)显示文摘The effect of Mo/HZSM-5 pretreatment at 973 K in inert(He), oxidizing(artificial air), and carburizing(CH4/He mixture) atmospheres on its performance in non-oxidative methane dehydroaromatization(MDA) was investigated. The effect of post-synthesis silylation on deactivation of external acid sites was also studied. Precarburization resulted in increased aromatic selectivity and improved catalyst stability. The benzene selectivity was the highest for the silylated Mo/HZSM-5 catalyst(benzene + naphthalene selectivity after 1 h on stream was close to 100%). The deactivation of precarburized zeolites was less pronounced than that of zeolites heated in air or He. During heating in air or He, larger fractions of the molybdenum oxide species diffused into the micropores than during heating in methane. Carburization of the molybdenum oxide species in the micropores during MDA resulted in the formation of molybdenum carbide particles, and these contributed to pore blocking, making the Brnsted acid sites inaccessible. The formation of molybdenum carbides during heating in methane resulted in a less mobile Mo phase. It is argued that the presence of molybdenum carbide particles in the micropores contributes to rapid catalyst deactivation, in addition to the formation of hard coke on the external surface. | Christiaan H.L.Tempelman Xiaochun Zhu Emiel J.M.Hensen | 2015 | 催化学报2015,36,6: | 4 |
| 4 | 实际海浪环境中大尺度自航船模的水弹性与耐波性试验研究(英文)显示文摘目的:为研究船舶在实际海浪环境中的水弹性与耐波性,本文提出一种新型模型试验技术。将相同船型不同尺度的模型分别在近海环境和水池环境中测量的试验数据进行比较,分析两种试验方法所得结果的差异,以说明水池模型试验方法所存在的问题,从而进一步证明新型试验技术的优越性。创新点:1.提出大尺度自航模型在实际海浪环境中实施水动力试验的技术和方法;2.将大尺度模型试验结果与传统水池模型试验结果进行比较,分析二者的差异。方法:针对某母型船,分别建造缩尺比为1:25和1:50的大尺度模型和小尺度模型。大尺度模型在自然海域的三维海浪中进行试验测量,而小尺度模型在水池长峰不规则波中进行试验测量。测量过程中保证两者的控制参数相似,并分析试验结果存在的差异。将数值计算的结果与大尺度模型试验的结果进行比较,并基于数值计算分析海浪的方向分布函数对结果的影响。结论:在近海海域中开展的大尺度模型耐波性与波浪载荷试验表明,本文提出的试验测试系统和试验方案是可行的。大尺度模型试验是在自然海浪环境中进行的,比水池环境更接近实船的实际航行环境,所得数据对于船舶设计和研发具有更高的参考价值和意义。 | Jia-long JIAO Hui-long REN Shu-zheng SUN Christiaan Adika ADENYA | 2016 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2016,17,6: | 3 |
| 5 | Total elbow arthroplasty is moving forward: Review on past, present and future显示文摘The elbow joint is a complex joint, which, when impaired in function, leads to severe disability. In some cases however, an arthroplasty might be an appropriate treatment. In the past four decades, large steps havebeen taken to optimize this treatment in order to achieve better post-operative outcomes. To understand these progresses and to discover aspects for upcoming improvements, we present a review on the past developments, the present state of affairs and future developments which may improve patient care further. | Ante Prki?

| 6 | Diagnosing, planning and evaluating osteochondral ankle defects with imaging modalities显示文摘This current concepts review outlines the role of diffe-rent imaging modalities in the diagnosis, preoperative planning, and follow-up of osteochondral ankle defects. An osteochondral ankle defect involves the articular cartilage and subchondral bone(usually of the talus) and is mostly caused by an ankle supination trauma. Conventional radiographs are useful as an initial imaging tool in the diagnostic process, but have only moderate sensitivity for the detection of osteochondral defects. Computed tomography(CT) and magnetic resonance imaging(MRI) are more accurate imaging modalities. Recently, ultrasonography and single photon emission CT have been described for the evaluation of osteochondral talar defects. CT is the most valuable modality for assessing the exact location and size of bony lesions. Cartilage and subchondral bone damage can be visualized using MRI, but the defect size tends to be overestimated due to bone edema. CT with the ankle in full plantar flexion has been shown a reliable tool for preoperative planning of the surgical approach. Postoperative imaging is useful for objective assessment of repair tissue or degenerative changes of the ankle joint. Plain radiography, CT and MRI have been used in outcome studies, and different scoring systems are available. | Christiaan JA van Bergen Rogier M Gerards Kim TM Opdam Maaike P Terra Gino MMJ Kerkhoffs | 2015 | World Journal of Orthopedics2015,6,11: | 3 |

| 9 | Developments in diagnosis and treatment of paediatric septic arthritis显示文摘Acute septic arthritis in children is an orthopaedic emergency.A delay in diagnosis and inappropriate treatment can result in devastating damage to the joint with lifelong disability as a consequence.The clinical presentation can be a diagnostic challenge,especially in young children.A recent systematic review showed that joint tenderness and fever are important signals of septic arthritis.Ultrasound is helpful in detecting the presence of a joint effusion.Plain radiographs may show bone changes but magnetic resonance imaging is the most reliable imaging study for detecting concomitant osteomyelitis.The diagnosis of acute septic arthritis is highly suggestive when pus is aspirated from the joint,in case of a positive culture or a positive gram stain of the joint fluid,or if there is a white blood-cell count in the joint fluid of more than 50000/mm3.Staphylococcus aureus is the most commonly cultured organism.Recent systematic reviews have identified the most effective drainage techniques,including needle aspiration,arthroscopy and arthrotomy,depending on the affected joint.After the drainage procedure it is important to monitor the clinical and laboratory outcomes.Additional drainage procedures may be necessary in select cases. | Cornelia M Donders Anne J Spaans Herbert van Wering Christiaan JA van Bergen | 2022 | World Journal of Orthopedics2022,13,2: | 2 |
| 10 | “双盲、安慰剂对照交叉设计研究植物药对于进食量、饱腹感、体重减轻及氧化应激的影响”的研究方案(英文)显示文摘背景:植物性治疗药物作为一种重要且尚未被完全开发的药用资源,可能有助于热量控制从而产生长期的减重功效。从藤黄果(Garcinia combogia Desr.)中提取的羟基柠檬酸可能通过影响与饱腹有关的神经通路而减少摄食量和减轻体重。方法与设计:本研究为双盲、安慰剂对照、交叉设计试验,共计划纳入48名超重或肥胖的健康受试者(体重指数25.0~39.9 kg/m^2,年龄50~70岁),研究两种剂量藤黄果来源的羟基柠檬酸对摄食量、饱腹感、体重减轻及氧化应激水平的影响。摄食量作为主要结局指标,根据受试者在测量日的早餐、午餐和晚餐的摄食量计算。与平行设计的研究相比,本研究所使用的受试者数量将大大减少。讨论:本研究选择藤黄果来源的羟基柠檬酸为研究对象是因为该药物能够安全地减少摄食量、减轻体重和降低氧化应激水平。我们将会在研究过程中探讨其可能的作用机制和安全指标。 | Stephen D.Anton Jonathan Shuster Christiaan Leeuwenburgh | 2011 | 中西医结合学报2011,9,11: | 2 |
| 11 | The COVID-19 pandemic and physical activity显示文摘The SARS-CoV-2-caused COVID-19 pandemic has resulted in a devastating threat to human society in terms of health,economy,and lifestyle.Although the virus usually first invades and infects the lung and respiratory track tissue,in extreme cases,almost all major organs in the body are now known to be negatively impacted often leading to severe systemic failure in some people.Unfortunately,there is currently no effective treatment for this disease.Pre-existing pathological conditions or comorbidities such as age are a major reason for premature death and increased morbidity and mortality.The immobilization due to hospitalization and bed rest and the physical inactivity due to sustained quarantine and social distancing can downregulate the ability of organs systems to resist to viral infection and increase the risk of damage to the immune,respiratory,cardiovascular,musculoskeletal systems and the brain.The cellular mechanisms and danger of this“second wave”effect of COVID-19 to the human body,along with the effects of aging,proper nutrition,and regular physical activity,are reviewed in this article. | Jeffrey A.Woods Noah T.Hutchinson Scott K.Powers William O.Roberts Mari Carmen Gomez-Cabrera Zsolt Radak Istvan Berkes Anita Boros Istvan Boldogh Christiaan Leeuwenburgh Helio Jose Coelho-Júnior Emanuele Marzetti Ying Cheng Jiankang Liu J.Larry Durstine Junzhi Sun Li Li Ji | 2020 | Sports Medicine and Health Science2020,2,2: | 2 |
| 12 | Changed degradation behavior of pesticides when present in mixtures显示文摘Soil microorganisms are indispensable for a healthy soil environment,where the fate of pesticides is contingent on microbial activity.Conversely,soil ecosystems can be distorted by all kinds of variables,such as agrochemicals.These crop protection products have been universally in use for decades in agriculture.In modern crop cultivation,fungicides are increasingly applied because of their high and broad effectivity on plant pathogens.While their use can enhance harvest yields,fungicides,particularly broad-spectrum ones,are responsible for the alteration of the soil microflora.Furthermore,successive and combined application of pesticides is an agronomic routine,which aggravates the concurrent existence of synthetic chemicals in the soil and marine environments.Mutual interactions of such different molecules,or their effects on soil life,can negatively impact the dissipation of biodegradable pesticides from the ecosystems.The direct effects of individual agrochemicals on microbial soil parameters,as well as agronomic efficiency and interactions of mixtures have been thoroughly studied over the past 80 years.The indirect impacts of mixtures on soil and aquatic ecosystems,however,may be overlooked.Moreover,the current regulatory risk assessment of agrochemicals is based on fate investigations of individual substances to derive predicted environmental concentrations,which does not reflect real agricultural scenarios and needs to be updated.In this article,we summarized the results from our own experiments and previous studies,demonstrating that the degradation of pesticides is impacted by the co-existence of fungicides by their effects on microbial and enzymatic activities in soil. | Andreas Schaeffer Christiaan Wijntjes | 2022 | Eco-Environment & Health2022,1,1: | 2 |
