Acta Oceanologica Sinica 1988年第2期7卷 226-236页

Procedures are described to extract, fractionate and analyze organic pollutants in environmental samples. The methods are based on organic solvent extraction to isolate the pollutants, liquid-solid adsorption chromatography to separate the various pollutants into four fractions, and analyses of the fractions using glass capillary gas-chromatography. Based on a number of considerations, the procedures were found suitable for the analyses of trace level organic pollutants in a variety of sample types. The data from these studies has provided important information on the biogeochemistry of organic pollutants in the aquatic environment.

We previously demonstrated that brief nonkilling neutrophil exposure diminishes the binding affinity of S. aureus penicillin-binding protein (PBP) 2. We sought to investigate further the role of the neutrophil in the alteration of antimicrobial activity and its interaction with PBP-2 by studying the activity of cefotaxime, which highly binds to PBP 2, and cephalexin, which minimally binds to PBP 2. Using S. aureus, cultured in vitro in sterile-filtered normal and neutrophil depleted abscess fluid, we sought to demonstrate an in vivo significance of the neutrophil effect upon the activity of antimicrobials that target PBP-2 by studying the same antimicrobials in an experimental S. aureus abscess. Rats were implanted with perforated tissue cages and infected with S. aureus;some rats were neutrophil depleted by mechlorethamine. Abscess fluids from normal and neutropenic abscesses were harvested, pooled, sterile-filtered and stored for the time-kill studies. Treatment studies were performed by administering either 300 μg/kg/d cefotaxime or cephalexin for 7 days in other rats with 24 hour-old tissue-cage S. aureus abscesses. In time-kill studies, cefotaxime was highly active against stationary phase S. aureus in MHB and in neutropenic abscess fluid, but less active in the non-neutropenic abscess fluid (p 10 kill, p = 0.029 vs. 0.81 ± 2.5, p = NS). These data suggest that neutrophil exposure, which diminishes S. aureus PBP-2 binding affinity [or total quantity], also adversely affects the antimicrobial activity of cefotaxime, which binds to PBP-2, as compared to cephalexin. Altered PBP targets from neutrophil exposure may be a mechanism of antimicrobial resistance within abscesses.

Case Reports in Clinical Medicine 2015年第12期4卷 376-380页

Patients presenting to emergency and urgent care centers with calf pain after long and short-haul flights are a common presentation throughout Europe. Patients fitting an epidemiological risk profile for cholelithiasis and presenting with right upper quadrant abdominal pain can also be a common presentation fitting of a specific patient profile. However, pulmonary hypertension can present in a nuanced and possible missed chronic and acute presentation. The patient case we present profiles a mildly obese 54-year-old Caucasian woman and recent holiday maker with unilateral calf pain and shortness of breath after traveling on a long-haul flight with tertiary symptoms of indigestion and epigastric discomfort indicative of gastroenteritis. This case highlights the required diligence for emergency physicians to maintain a high index of suspicion and broad differential diagnosis in the undifferentiated patient with seemingly common or classic presentations. We find that a serendipitous definitive diagnosis is made by following a systematic and organized approach.

这种笑眯眯的"大老鼠",是澳洲最快蹿红的动物。甚至有专门为它们设置的上传自拍照的社交网站主页。它们眼睛小小圆圆的,尾巴像老鼠,像布偶一样可爱,听说皮卡丘就是参考它们设计的。它们虽然长得像老鼠,但是前面有小育儿袋,而且与大袋鼠一样喜欢蹦蹦跳跳地走,是货真价实的袋鼠。这些小家伙们脸上带着令人难以抗拒的可爱的笑容,醒着或者睡着,都能捕捉到它们可爱的笑脸,被人们封为"全世界最快乐的动物"。每次看向相机,都会嘴角上扬,露出兴致勃勃的笑容,

作者： Bill quinn

谁是全世界最优秀的冰球球员？10年之后，我就有办法揭晓答案了。不过就目前而言，北美“职业冰球联盟”。（简称NHL）球迷们可从希尼·克劳斯比和亚历山大·欧瓦钦之间择其——虽然这很像是要从巧克力和龙虾之间挑哪个最美味。
