transcatheter ablation of atrioventricular accessory pathway is the therapy of choice in symptomatic patients. the ablation of posteroseptal accessory pathways thas some important points due to its anatomical location. catheter ablation of posteroseptal accessory pathways via left side approach is time consuming with low success rate and higher complications. we performed successful transcathet...

background: echinococcus multilocularis is a tiny tapeworm, responsible for 0.3~0.5 million alveolar echinococcosis in humans. methods: we searched relevant papers published between 1981 and 2013 based on the database sources such as pubmed and google scholar, and collected and integrated the data for analysis. results: the parasite is able to use host-originated molecules to modulate its devel...

background and objectives: silymarin is a unique flavonoid complex with documented hepatoprotective properties. silybum  marianum hairy root culture as a source for producing silymarin has been an important strategy for study the cell signaling pathway. in the present investigation trichoderma strains- silybum marianum hairy root cultures interactions have been studied. methods: the effects of ...

metabolic syndrome (mets) is characterized by a cluster of cardiovascular risk factors that include: abdominal obesity, dyslipidaemia, hypertension, insulin resistance and impaired glucose tolerance. recent genome wide association studies have identified several susceptibility regions involved in lipid metabolism that are also associated with mets. we have explored the association of 9 genetic ...

infection with human immunodeficiency virus (hiv) is a progressive condition which may cause endothelial dysfunction and liver damage leading to coagulopathy. with adventure of highly active antiretroviral therapy (haart), life expectancy has prolonged in hiv positive patients but several acquired immunodeficiency syndrome (aids)-related conditions such as coagulopathies are responsible for ass...

The superior efficacy of atypical vs. classical antipsychotic drugs to treat negative symptoms and cognitive deficits in schizophrenia appears related to their ability to enhance mesocortical dopamine (DA) function. Given that noradrenergic (NE) transmission contributes to cortical DA output, we assessed the ability of NE-targeting drugs to modulate DA release in medial prefrontal cortex (mPFC)...

Idiopathic Parkinson's disease (PD) is often accompanied by a pattern of executive deficits similar to those found in patients with frontal lobe lesions. We investigated whether such cognitive deficits are attributable to frontal lobe dysfunction as a direct consequence of impaired mesocortical dopaminergic transmission or an indirect consequence of impaired nigrostriatal dopaminergic function....

It is no longer tenable to attribute all the antipsychotic action of antipsychotic drugs to dopamine (DA) D2 receptor blockade and subsequent development of depolarization inactivation of the mesolimbic or mesocortical DA neurons. The chief evidence for this position is that clozapine (CLOZ) does not differ from typical antipsychotic drugs in these regards but is more effective than typical neu...
