Hafnium oxide layer-enhanced single-walled carbon nanotube field-effect transistor-based sensing platform.

Single-walled carbon nanotube-based field effect transistors (SWCNT-FETs) are ideal candidates for fabricating sensors and have been widely used for chemical sensing applications. SWCNT-FETs have low selectivity because of the environmentally sensitive electronic properties of SWCNTs, and SWCNT-FETs also show a high noise signal and poor sensitivity because of charge trapping from Si-OH hydration of the SiO/Si substrate on the SWCNTs. Herein, poly (4-vinylpyridine) (P4VP) was used for noncovalent attachment to SWCNTs and selective binding to copper ions (Cu).

Ziyin Bushen Decoction Alleviates Perimenopausal Syndrome in Rats by Enhancing Estradiol Production.

Endovascular treatment of Budd-Chiari syndrome.

Background: Budd-Chiari syndrome (BCS) is a posthepatic portal hypertension caused by the obstruction of the lumen of the hepatic veins or the proximal inferior vena cava (IVC). This study aimed to evaluate the clinical experience of interventional therapy for Budd-Chiari syndrome.

Methods: IVC venography was carried out first, the obliteration or stenosis in the IVC was opened or dilated with the hard guided wire or Rups100 puncture needle and balloon, then a stent was routinely implanted for the type of obliteration or stenosis.

Nanoliposome-mediated FL/TRAIL double-gene therapy for colon cancer: in vitro and in vivo evaluation.

Objective: To investigate the therapeutic effects of cationic nanoliposome-mediated gene therapy combined with immunotherapy for colon cancer treatment.

Methods: Recombinant plasmids containing green and red fluorescent protein reporter genes were constructed using gene cloning methods. Gene-carrying cationic nanoliposomes were prepared based on the electrostatic adherence principle and then transfected into dendritic cells (DC), which were transplanted into colon cancer cells.

[Studying the therapeutic effects of hemoperfusion with continuous venovenous hemofiltration on the patients with acute paraquat poisoning].

Objective: To explore the therapeutic effects of hemoperfusion (HP) with continuous venovenous hemofiltration (CVVH) on the patients with acute paraquat poisoning.

Methods: Ninety-one patients with acute paraquat poisoning were randomly divided into HP group (49 cases) and HP-CVVH group (42 cases). The mortality, survival duration and the death causes between the two groups were compared and analyzed.

Correlation between the expression of the BAG-1 gene and clinicopathologic factors in colorectal cancer.

Objective: The present study aims to investigate the expression and significance of the anti-apoptotic gene Bag-1 in colorectal cancer and to evaluate the relationship between the gene and the disease.
