Short communication: Upregulation of hypoxia/reoxygenation-induced Shc3 by downregulated miR-455-5p, suppresses trophoblast invasion and is associated with placental inflammation and angiogenesis in preeclampsia.

Preeclampsia is characterized by insufficient invasion of extravillous trophoblasts and is a consequence of failed adaption of extravillous trophoblasts to changes in the intrauterine environment developing embryo. Specific miRNAs are implicated in the development of preeclampsia (PE). miR-455-5p is present at low levels in PE but its role is not known.

Clinicopathological and Prognostic Roles of STAT3 and Its Phosphorylation in Glioma.

Glioma is defined as a common brain tumor which causes severe disability or death. As many genes are reported to relate with glioma's occurrence and development, their prognostic and therapeutic value still remains uncertain. This study aimed at investigating the association between STAT3/p-STAT3 and glioma prognosis.

Ground-based observations of ultraviolet and total solar radiation in Shenyang, northeast China.

Objective: This work explores the diurnal variation of Solar ultraviolet radiation (UVR) and total solar radiation (TSR) in northeast China, using daily observations of UVR and TSR in Shenyang.

Methods: UVR and TSR measurements were carried out from March 1st, 2006 to December 31st, 2009 in Shenyang, Liaoning province, China (41°51' N, 123°27' E).

Results: Both TSR and UVR showed seasonal variation, reaching the highest levels in summer and the lowest in winter.

Diurnal variations in solar ultraviolet radiation at typical anatomical sites.

Objective: Solar ultraviolet (UV) radiation is an important environmental factor that affects human health. The understanding of diurnal variations of UV radiation at anatomical sites may be helpful in developing ways to protect humans from the harmful effects of UV radiation.

Methods: In order to characterize the diurnal variations, the UV exposure values were measured at 30 min intervals by using Solar-UV Sensors and a rotating manikin in Shenyang city of China (41 degrees 51'N, 123 degrees 27'E).

[Study on water processing conditions of Realgar].

Objective: To optimize the water processing (shui-fei) condition of Realgar.

Methods: The processing conditions were optimized by L9 (3)4 orthogonal design with three factors as water dose, process times and dryness temperature. The content of dissolved arsenic As(III) in Realgar was tested by High Performance Liquid Chromatography-hydride generation on-line coupled with atomic fluorescence spectrometry (HPLC-HG-AFS).

Occurrence of fumonisin B(1) in corn from the main corn-producing areas of China.

Fumonisin B(1) (FB(1)) is the most abundant of the fumonisin mycotoxins, mainly produced in maize by F. verticillioides and F. proliferatum.

[Development of monoclonal antibody against fumonisin B1 and ELISA-kit of quantitative analysis for fumonisin B1].

Objective: To detect the contamination level of fumonisin B1 in grain, and to develop rapid detection kit that possess patent of China.

Methods: Hybridoma cell line excreting monoclonal antibody against fumonisin B, was produced using B cell hybridoma technique and develop a rapid, sensitive, quantitative ELISA-kit for detection fumonisin B1.

Results: The monoclonal antibody used in the ELISA-kit were tested for subtype as IgG1 and its affinity constant was 8.
