Non-immersed zigzag microalgae biofilm overcoming high turbidity and ammonia of wastewater for muti-pollutants bio-purification.

Biological treatment that utilizes microalgae technology has demonstrated outstanding efficacy in the wastewater purification and nutrients recovery. However, the high turbidity of the digested piggery wastewater (DPW) leads to serious light attenuation and the culture mode of suspended microalgae results in a huge landing area. Thus, to overcome light attenuation in DPW, a non-immersed titled zigzag microalgae biofilm was constructed by attaching it onto a porous cotton cloth.

Elevated Expressions of Survivin and Endoglin in Patients with Hepatic Carcinoma.

Objective: To investigate expression profiles of survivin and endoglin in patients with hepatic carcinoma.

Materials And Methods: Cancerous tissues (hepatic carcinoma group) of 48 patients with hepatic carcinoma and adjacent noncancerous hepatic tissues (control group) were used as objects of study. Histopathological staining [hematoxylin & eosin (H&E) staining] was used to study the pathological differences in hepatic tissues between hepatic carcinoma group and control group.

miR-21 promotes proliferation and inhibits apoptosis of hepatic stellate cells through targeting PTEN/PI3K/AKT pathway.

To investigate the effect of microRNA 21 (miR-21) on hepatic stellate cells (HSCs) proliferation and apoptosis, and further to study its potential mechanisms. LX-2 cells were divided into miR-21 mimic group (Mimic), miR-21 mimic negative control group (NM), miR-21 inhibitor group (Inhibitor), miR-21 inhibitor negative control group (NC), and blank control group (Control). The cell proliferation was detected by CCK-8 assay and the cell migration and invasion were detected by scratch and transwell assay.
