A Review of the Beetle Genus of Taiwan, with Description of a New Species (Coleoptera, Latridiidae).

The genus in Taiwan was previously known to contain three species, Johnson, Johnson, and (Fabricius). Johnson and Johnson are known from the Palearctic, and (Fabricius) is a cosmopolitan species. In this study, the genus in Taiwan is reviewed for the first time, with three species being recognized, including two recorded species, Johnson and Johnson, and a species new to science, sp.

Beetles of the Genus (Coleoptera, Histeridae), with Description of a New Species from Taiwan.

The genus Bickhardt, 1912 was previously only known to contain a single species, Bickhardt, 1912, and had only been recorded from Southeast Asia. In this study, a new species found in Taiwan, sp. nov.

Ultramorphological Characteristics of Pic (Coleoptera: Ptinidae) and a New Species of Westwood (Hymenoptera: Bethylidae): A Book-Boring Beetle and Its Natural Enemy in Taiwan.

Libraries are invaluable resources, documenting significant events that have shaped human history. However, the preservation of old books is severely threatened by insects commonly referred to as bookworms. In this study, a sample of infested books in a historic library in Taiwan was randomly selected and examined.

Analysis of ten abused drugs in urine by large volume sample stacking-sweeping capillary electrophoresis with an experimental design strategy.

A statistical tool equipped with Plackett-Burman design (PBD) and central composite design (CCD) was used for fast stacking analysis of ten frequently consumed drugs, namely codeine, morphine, methamphetamine, ketamine, alprazolam, clonazepam, diazepam, flunitrazepam, nitrazepam and oxazepam, by capillary electrophoresis (CE). This statistical design is expected to help quick analysis with few procedures, avoiding tedious work required because of the large number of variables or parameters. A large volume sample stacking (LVSS)-sweeping CE is developed for concentrating and analyzing the 10 abused drugs.

Analysis of carbamazepine and its five metabolites in serum by large-volume sample stacking-sweeping capillary electrophoresis.

This study establishes a method, using different buffer conductivities and large-volume sample stacking (LVSS)-sweeping capillary electrophoresis, for analysis of carbamazepine (CBZ) and its five metabolites in serum. The capillary (50/60 cm) was filled with a high concentration of background electrolyte (150 mM phosphate, pH 3.5, containing 15 % methanol), followed by a large volume of samples (10 psi, 20 s) with low-concentration buffers (5 mM phosphate, pH 3.

Micellar electrokinetic capillary chromatographic method for the separation and quantitation of multiple amino acids as naphthoxy derivatives in pharmaceutical formulations.

The MEKC method is described for the quantitative analysis of 17 amino acids (AA) in pharmaceutical products. The method is based on simply derivatizing the AA with (2-naphthoxy)acetyl chloride under mild conditions. The resulting derivatives were separated by MEKC with borate buffer (35 mM; pH 9.

Field-amplified sample stacking in capillary electrophoresis for the determination of clozapine, clozapine N-oxide, and desmethylclozapine in schizophrenics' plasma.

A method of field-amplified sample stacking in capillary electrophoresis is described for the simultaneous determination of clozapine (CZP) and its metabolites, clozapine N-oxide (CNO), and desmethylclozapine (DMC), in human plasma. Plasma (0.2 mL) was extracted with organic solvents (ethyl acetate/n-hexane/isopropyl alcohol, 8/1/1 by volume) and centrifuged.

Quantitative enantiomeric analysis of chlorcyclizine, hydroxyzine, and meclizine by capillary electrophoresis.

A simple capillary zone electrophoresis method was developed for the quantitative enantiomeric analysis of piperazine antihistamines with teratogenic suspicion in animals. Enantioseparation of chlorcyclizine, hydroxyzine, and meclizine was performed in glycine buffer (0.6 mol L(-1); pH 3.
