Elimination of typical polycyclic musks in a full-scale membrane bioreactor combined with anaerobic-anoxic-oxic process in municipal wastewater treatment plant.

The objective of this study was to investigate the removal of 11 synthetic polycyclic musks in a municipal wastewater treatment plant located in Jilin, China, by using a membrane bioreactor combined with anaerobic-anoxic-oxic process. The analysis of synthetic polycyclic musks was conducted with gas chromatography/mass spectrometry after solid-phase extraction. The removal efficiency of 11 synthetic polycyclic musks ranged from 65.

Evaluation of the Interference of Hemoglobin Variant J-Bangkok on Glycated Hemoglobin (HbA1c) Measurement by Five Different Methods.

The interference of the hemoglobin variant (Hb J-Bangkok) was evaluated on 4 different glycated hemoglobin assays and compared with a reference immuno assay. An overall test of coincidence of 2 least-squares linear regression lines was performed to determine whether the presence of Hb J-Bangkok caused a statistically significant difference in HbA1c results compared with a reference immuno assay. Statistical analysis was performed on the difference of the estimated average glucose calculated from HbA1c values and fasting plasma glucose in the Hb J-Bangkok variant group using the different detection systems.

Effects of hemoglobin variants HbJ Bangkok, HbE, HbG Taipei, and HbH on analysis of glycated hemoglobin via ion-exchange high-performance liquid chromatography.

Background: To explore the effects of HbJ Bangkok, HbE, HbG Taipei, and α-thalassemia HbH on the results of HbA1c assessment using ion-exchange high-performance liquid chromatography (IE-HPLC).

Methods: We enrolled five patients in which the results of the IE-HPLC HbA1c assay were inconsistent with the average levels of FBG. We performed hemoglobin capillary (Hb) electrophoresis using whole-blood samples.

[Spectroscopic Studies on the Host Plant Selection Mechanism of Trabala vishnou gigantina Yang (Lepidoptera: Lasiocampidae)].

Trabala vishnou gigantina Yang (Lepidoptera: Lasiocampidae) is a polyphagous forestry pest whose periodic breaking out results in great economic damage including total crop failure to forestry and fruit production in China. In this study, in order to improve the understanding of the host plant selection mechanism of T. vishnou gigantina larvae, locust, caragana, willow, poplar, apricot and sea-buckthorn were used as potential host plants for the test.

[Amino-terminal pro-brain natriuretic peptide and brain natriuretic peptide measurements under various detection conditions in patients with chronic heart failure].

Objective: To find the potential interference factors for the detection of NT-proBNP and BNP in patients with chronic heart failure.

Methods: EP15-A2 issued by Clinical and Laboratory Standards Institute (CLSI) was employed to compare the precision and accuracy of commercial NT-proBNP and BNP analyzer electrochemiluminescence immunoassay system Cobas E601 and chemiluminescence system ADVIA Centaur. Moreover, NT-proBNP and BNP were detected in different time interval and in different interfered sampling conditions (haematolysis, choloplania, lipemia).

[Study on the mechanism of THP-1 cell differentiation imduced by a new steroidal drug NSC67657].

Objective: To study the potential mechanism of the new steroidal drug NSC67657 induced leukemic cells differentiation.

Methods: Cell proliferation was assayed by MTT assay. Surface antigen CD14 on THP-1 cells treated by NSC67657 at different time different concentration, was detected by flow cytometry (FCM).

[Effect of C/EBPalpha on the monocytic differentiation of HL60 cells induced by NSC67657].

Objective: To figure out the function of C/EBPalpha in the monocytic differentiation of HL60 cells induced by a new steroidal drug NSC67657.

Methods: The differentiation of HL60 cells was induced by NSC67657, and the cell surface antigen CD14 expression was detected by flow cytometry. The gene and protein expressions of CCAAT enhancer binding protein alpha (C/EBPalpha) before and after the induction of cell differentiation were determined by RT-PCR and Western blot.
