Single nucleotide polymorphisms (SNPs) are the most abundant genetic polymorphisms and are responsible for many genetic diseases and cancers. In general, SNPs detection is performed by a single probe system (SPS), in which a single probe specifically hybridizes to one target. However, with the use of this method it is hard to improve the hybridization specificity and single mismatched discrimination factors (DF). In addition, the multiprobe system (MPS) requires complex probe designs and introduces at least one auxiliary probe except for the probe complementary to the target, resulting in a complicated detection system...

BACKGROUND: The anterolateral thigh (ALT) flap has been widely used in reconstruction of soft tissue defects. The anatomic variations of perforators increase the difficulties of flap elevation. The ABC system has been described for locating the most common three perforators in Western populations. Less evidence has been found regarding whether it is suitable for Chinese population. The purpose of this study is to explore the improvement of preoperative location technology and flap design for Chinese people...

Amylomaltase from Thermus aquaticus catalyzes intramolecular transglycosylation of alpha-1,4 glucans to produce cyclic alpha-1,4 glucans (cycloamyloses) with degrees of polymerization of 22 and higher. Although the amylomaltase mainly catalyzes the transglycosylation reaction, it also has weak hydrolytic activity, which results in a reduction in the yield of the cycloamyloses. In order to obtain amylomaltase with less hydrolytic activity, random mutagenesis was perfromed for the enzyme gene. Tyr54 (Y54) was identified as the amino acid involved in the hydrolytic activity of the enzyme...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
