Radix Astragali is a popular herb used in traditional Chinese medicine for its proimmune and antidiabetic properties. However, methods are needed to help distinguish Radix Astragali from its varied adulterants. DNA barcoding is a widely applicable molecular method used to identify medicinal plants. Yet, its use has been hampered by genetic distance, base variation, and limitations of the bio-NJ...

BACKGROUND Fang-Ji-Huang-Qi-Tang (abbreviated as FJHQT), composed by six medicinal herbs including Radix Stephania Tetrandra, Radix Astragali, Rhizoma Atractylodis Macrocephalae, Radix Glycyrrhizae, Rhizoma Zingiberis and Fructus Ziziphi Jujubae, is a frequently Chinese prescription for treating painful and inflammatory disorders such as rheumatoid arthritis. When Radix Stephania Tetrandra was ...

Humans are accustomed to counting in a positional number system – decimal radix. Nearly all computer systems operate on another positional number system – binary radix. From the standpoint of representation, such positional systems are compact: given a radix b, one can represent b distinct numbers with n digits. Each choice of the digits di ∈ {0, . . . , b−1}, i = 0, . . . , n−1, results in a d...

The generating series of a radix-rational sequence is a rational formal power series from formal language theory viewed through a fixed radix numeration system. For each radix-rational sequence with complex values we provide an asymptotic expansion for the sequence of its Cesàro means. The precision of the asymptotic expansion depends on the joint spectral radius of the linear representation of...

Two’s complement multipliers are important for a wide range of applications. Paper describes a technique to reduce by one row the maximum height of the partial product array generated by Radix-4 Booth’s multiplier, without any increase in the delay of the partial product generation stage. The design of 8 bit and 16 bit multiplication scheme using different types of multiplier like Array multipl...

Traditional Chinese medicine Radix phytolaccae is the dried root of Phytolacca acinosa Roxb and Phytolacca americana L. Radix phytolaccae has multiple efficacies of antibiosis, antivirus, antiinflammatory, antitumor, enhancing immunity, eliminating phlegm and relieving asthma. In this study, we developed a tissue (liver, kidney and heart) metabolomic method by gas chromatography-mass spectromet...

Topical traditional Chinese medicine- (TTCM-) related contact dermatitis is not uncommon but ignored. Patch and photopatch tests using 6 individual herbal ingredients and Bai-Zhi-Kao (BZK; ), a skin-lightening TTCM preparation, were conducted on 30 participants. Twenty-five subjects showed at least 1 positive reaction, including 6 (20.0%) participants who reacted to BZK. The majority reacted to...
