Neuroprotection by plumbagin involves BDNF-TrkB-PI3K/Akt and ERK1/2/JNK pathways in isoflurane-induced neonatal rats.

Objectives: This study was designed to assess the effects of plumbagin on isoflurane-induced neurotoxicity.

Methods: Neonatal Sprague Dawley rat pups were treated with plumbagin (50, 100 or 150 mg/kg body weight, orally) from postnatal day 2. The pups on postnatal day 7 were subjected to isoflurane (0.

[Characterization of Phosphorus Forms in Organic Composts and Their Effects on Leaf Phosphorus Content of in Chinese Chestnut Producing Area].

Characterization of the forms of phosphorus (P) in four organic composts including compost of hulls and leaves of , edible fungi residues, corn stalks and chicken manure (BYZ), compost of edible fungi residues and chicken manure(ZF), composts of hulls and leaves of , edible fungi residues and chicken manure (BZ1 and BZ2) in Chinese chestnut producing area was conducted by sequential P fractionation developed by Dou . Field trial was conducted to study the effects of compost application on leaf phosphorus content of . The results showed that total phosphorus content(TP) of organic composts ranked as follows:BZ1(10.

[Determination the Change of Main Trace Elements in the Ovary with Self- and Cross-Pollination of Chinese Chestnut by ICP-MS].

Castanea mollissima Blume has potential as an non-wood forest trees that have been cultivated for thousands of years in China. In order to elucidate the trace elements of chestnut ovary, the major trace elements of self- and cross-pollination chestnut ovary were determined by inductively coupled plasma mass spectrometry. The results showed that self- and cross-pollination 5-50 d, six trace elements trends showed fluctuations.
