Spermine oxidase promotes bile canalicular lumen formation through acrolein production.

Spermine oxidase (SMOX) catalyzes oxidation of spermine to generate spermidine, hydrogen peroxide (HO) and 3-aminopropanal, which is spontaneously converted to acrolein. SMOX is induced by a variety of stimuli including bacterial infection, polyamine analogues and acetaldehyde exposure. However, the physiological functions of SMOX are not yet fully understood.

[Two cases of aortoenteric fistula with gastrointestinal bleeding].

Aortoenteric fistula (AEF) is a life-threatening condition that can present with gastrointestinal (GI) bleeding. AEFs have been classified into primary and secondary types. Primary AEF (PAEF) is a direct communication between the aorta and the GI tract.

Experimental studies of remarkable monoamine releases and neural resistance to the transient ischemia and reperfusion.

Introduction: The literature described that neural damage caused by ischemia definitely occurs in brain areas. However, few studies have shown real-time changes of extracellular monoamine levels at the time of transient ischemia.

Methods: We examined changes in the responses of dopamine (DA) and serotonin (5-HT) release in the nucleus accumbens (ACC) of rats treated with four-vessel occlusion (4VO) in experiment 1.

[Clinical impact of addition of bevacizumab to the first-line chemotherapy regimen in the treatment of patients with metastatic colorectal cancer].

Background: Combination regimens containing bevacizumab(BV)are regarded as one of the standard first-line chemotherapy (1stCTx) regimens in the treatment of metastatic colorectal cancer (mCRC). However, some patients cannot be treated with BV because of the short interval from the palliative operation or other reasons. We present a study of some patients who were treated with add-on BV in the middle of the 1stCTx before disease progression(referred to as "midway BV" regimen hereafter), and here, we report the efficacy of the midway BV regimen as observed in our patients.
