BACKGROUND Rhizoma Chuanxiong (RC) is the dried rhizome of Ligusticum chuanxiong Hort., and various types of processed Rhizoma Chuanxiong (PRC) are widely used in China. However, quality assurance and quality control of these processed medicines remain challenging. This study aims to investigate the chemical compositions of various PRC preparations by a high-performance liquid chromatography (H...

Squalene (SQ) is a lipid produced in sebaceous gland involved the vital skin barrier function. Its peroxidation leads to accumulation of SQ epoxides and monohydroperoxides causing various damages as hyperpigmentation, wrinkles, acne. Monitoring effects cosmetic cream on evolution content their oxidation during clinical studies represent numerous analysis; highlighting need combine molecule anal...

BACKGROUND The Canadian Institute for Health Information (CIHI) collects hospital discharge abstract data (DAD) from Canadian provinces and territories. There are many demands for the disclosure of this data for research and analysis to inform policy making. To expedite the disclosure of data for some of these purposes, the construction of a DAD public use microdata file (PUMF) was considered. ...

CONTEXT The histologic patterns of diffuse alveolar damage (DAD), bronchiolitis obliterans with organizing pneumonia (BOOP), and eosinophilic pneumonia (EP) are well-recognized histologic patterns of lung injury associated with an acute or subacute clinical presentation. We have recognized acute fibrinous and organizing pneumonia (AFOP) as a histologic pattern, which also occurs in this clinica...

To the Editor: Increased plasma homocysteine is now well established as a risk factor for cardiac, cerebral, and peripheral vascular disease (1). Despite this, the test is not widely available. This is partly because of practical difficulties in sample collection. The homocys-teine concentration increases in whole blood by up to 10% per hour unless samples are kept on ice and separated within 6...

At the end of January I travelled to the States to speak at and attend the first O'Reilly Bioinformatics Technology Conference. It was a large, well-organized and diverse meeting with an interesting history. Although the meeting was not a typical academic conference, its style will, I am sure, become more typical of meetings in both biological and computational sciences.Speakers at the event in...

Two novel ruthenium complexes belonging to the Ru(II)(DAD)(Cym) (DAD = diazadienyl) (Cym cymene) compound family are introduced as promising precursors. Their chemical nature, potential for vapor deposition (CVD), and possibly atomic layer (ALD) demonstrated. The development of nonoxidative CVD processes yielding high-quality Ru thin films is realized. Chemical analyses exercised that vitiate d...

INTRODUCTION Patients with HIV infection are at increased risk of developing cardiovascular disease (CVD) due to complex interactions between traditional CVD risk factors, antiretroviral therapy (ART) and HIV infection itself (1). Prevention of CVD is essential as it remains the most common serious non-AIDS event and contributes significantly to all-cause mortality. A cardiovascular risk-assess...
