Interest in the analysis of low abundance neuropeptides particularly using matrix-assisted laser desorption/ionization time-of-flight mass-spectrometry (MALDI–TOF–MS) is increasing because these neuropeptides are essential to the mechanism of tra

Background: It is well known that male-pattern baldness (MPB) is not started from occipital, but frontal or scalp of head. We can assume that distribution of androgenic steroids is different for each region of the head. Objective: We hypothesize that

To development an immunodetection method for DDT, 1,1,1-trichloro-2,2-bis(4-chorophenyl)ethane (p,p'-DDT) and its metabolites (p,p'-DDA, p,p'-DDE, p,p'-DDD), five derivatives of DDT haptens have been synthesised and characterized as coating ligands f

Trifluoroacylated, trimethylsilylated and methylated mesocarb (3-(1-methyl-2-phenylethyl)-5-[[(phenylamino) carbonyl]amino]-1,2,3-oxadiazolium) were analyzed by gas chromatography/mass spectrometry (GC/MS). In trifluoroacylation, N-trifluoroacylated

Micellar electrokinetic chromatography (MEKC) was successfully and conveniently applied to the chiral separation with the addition of cyclodextrins (CDs) as chiral selector to the running buffer. Chiral separation depended on the type of CD; in parti

The side chain of phenolalkylamines containing a bifunctional group was derivatized as the cyclic boronate, and then the residual phenolic group was trimethylsilylated. The resulting derivatives were single reaction products in each case, with good g
