Patients in the control group received swallowing training on the basis of conventional treatment, whereas those in the observation group additionally received "Tong Guan Li Qiao" needling treatment, both groups were treated for 4 weeks.

Nano-selenium alleviates cadmium-induced cerebellar injury by activating metal regulatory transcription factor 1 mediated metal response.

This study aims to investigate the role of metal regulatory transcription factor 1 (MTF1)-mediated metal response in cadmium (Cd)-induced cerebellar injury, and to evaluate the antagonistic effects of nano-selenium (Nano-Se) against Cd toxicity. A total of 80 chicks (1 d old, male, Hy-Line Variety White) were randomly allocated to 4 treatment groups for 3 months: the control group (fed with a basic diet,  = 20), the Nano-Se group (basic diet with 1 mg/kg nano-Se 1 mg/kg Nano-Se in basic diet,  = 20), the Nano-Se + Cd group (basic diet with 1 mg/kg Nano-Se and 140 mg/kg CdCl,  = 20) and the Cd group (basic diet with 140 mg/kg CdCl ,  = 20). The results of the experiment showed that the Purkinje cells were significantly decreased with their degradation and indistinct nucleoli after Cd exposure.

Cadmium Through Disturbing MTF1-Mediated Metal Response Induced Cerebellar Injury.

Cadmium (Cd) is a toxic environmental contaminant, which bio-accumulate in animals through the food chain. Cerebellum is one of the primary target organs for Cd exposure. In this study, we established a chronic Cd exposure model; 60 chickens were treated with Cd (0 mg/kg, 35 mg/kg, 70 mg/kg) for 90 days.

The protective effect of nnano-selenium against cadmium-induced cerebellar injury via the heat shock protein pathway in chicken.

Cadmium (Cd) is one of the toxic environmental heavy metals that poses health hazard to animals due to its toxicity. Nano-Selenium (Nano-Se) is a Nano-composite form of Se, which has emerged as a promising therapeutic agent for its protective roles against heavy metals-induced toxicity. Heat shock proteins (HSPs) play a critical role in cellular homeostasis.

Cadmium induced cerebral toxicity via modulating MTF1-MTs regulatory axis.

Metal-responsive transcription factor 1 (MTF1) participates in redox homeostasis and heavy metals detoxification via regulating the expression of metal responsive genes. However, the exact role of MTF1 in Cd-induced cerebral toxicity remains unclear. Herein, we explored the mechanism of Cd-elicited cerebral toxicity through modulating MTF1/MTs pathway in chicken cerebrum exposed to different concentrations of Cd (35 mg, 70 mg, and 140 mg/kg CdCl) via diet.

pH Dependent synthesis of two isomeric dinuclear Cerium(II) complexes: Structures, DNA interactions, cytotoxic activity and apoptotic study.

Two isomeric dinuclear Cerium(II) complexes 1 and 2, formulated as Ce(phen)(NO)(L) [L=phenylacetic acid, phen=1,10-phenanthroline] was synthesized under solvothermal conditions at different pH values. The two complexes were characterized by elemental analysis, IR and single crystal X-ray diffraction. Complexes 1 and 2 were studied the binding with DNA and against cytotoxic activity.

Syntheses, characterization, interaction with DNA, cytotoxic and apoptosis of two novel complexes of Zn(II) and Mn(II) with 2-methyl-1H-4,5-imidazoledicarboxylic acid.

Two new complexes, Zn(L)2(H2O)2 (1) and Mn(L)2(H2O)2 (2) [L = 2-Methyl-1H-4,5-imidazoledicarboxylic acid] were synthesized and characterized by elemental analysis, infrared spectroscopy, and single crystal X-ray diffraction. Intramolecular weak interactions, such as hydrogen-bond and intermolecular interactions were presented in the complexes. The activities of the complexes binding with DNA, and cytotoxic activities were studied.

Association between remote organ injury and tissue polyamine homeostasis in acute experimental pancreatitis - treatment with a polyamine analogue bismethylspermine.

Experimental pancreatitis is associated with activation of polyamine catabolism. The polyamine analog bismethylspermine (Me(2)Spm) can ameliorate pancreatic injury. We investigated the roles of polyamine catabolism in remote organs during pancreatitis and explored the mechanism of polyamine catabolism by administering Me(2)Spm.

Polyamine catabolism in relation to trypsin activation and apoptosis in experimental acute pancreatitis.

Background: Overinduced polyamine catabolism (PC) in a transgenic rat model has been suggested to be a mediator of trypsin activation which is important in acinar cell necrosis. PC has also been observed in experimental taurodeoxycholate pancreatitis. We hypothesized that PC may be a mediator of trypsin activation in taurodeoxycholate pancreatitis.

[Method study on calcium and phosphorus simultaneous determination by microwave-digestion and ICP-MS].

As a pre-digestion method of breast milk microwave-digestion was adopted in this method, and the contents of calcium and phosphorus were determined by ICP-MS at the same time. By optimizing conditions of digestion and ICP-MS, appropriate internal elements and the isotope mass number and EPA200.8 interference calibration equation were chosen.

Changes in blood polyamine levels in human acute pancreatitis.

Objective: Experimental studies have shown that pancreatic activation of polyamine catabolism occurs during the early stage of acute pancreatitis. Changes in pancreatic polyamines are reflected in the red blood cell (RBC) polyamine contents, correlating with the extent of pancreatic necrosis. The aim of this human study was to examine the changes in polyamine levels in the RBCs of patients with acute pancreatitis.

Pancreatic injury response is different depending on the method of resecting the parenchyma.

Objectives: The present study was performed to compare the pancreatic injury response on the parenchymal resection either with ultrasonic scissors, electrocautery, or surgical scalpel.

Methods: A 1 x 0.5 cm piece of rat pancreas was resected from side of the pancreas either with ultrasonic scissors (Harmonic Scalpel; UltraCision, Ethicon Endosurgery Inc.

Effects of diameter, number and tightness of sutures on pancreatic injury response.

Background: We have experimental data indicating that the pancreas is easily damaged by any intervention. The present study compared the effects of suture diameter, number of needle passes and suture tightness on rat pancreas.

Methods: Under anesthesia, rat pancreas was sutured either with one loose stitch of 6-0 polydioxanone (PDS II) or 3-0 PDS II, with 5 passes of loose running 6-0 PDS II, or with 6-0 PDS II loop tightened to 0.

A polyamine analog bismethylspermine ameliorates severe pancreatitis induced by intraductal infusion of taurodeoxycholate.

Background: Stable polyamine homeostasis is important for cell survival and regeneration. Our experimental studies have shown that catabolism of spermidine and spermine to putrescine is associated with the development of pancreatitis. We investigated the pathogenetic role of polyamine catabolism by studying the effect of a methylated polyamine analog on taurodeoxycholate-induced acute experimental pancreatitis.
