Global climate change has been considered to be one of the key factors leading to declines and losses of amphibian *** global warming is one of the acknowledged causes of fluctuations of amphibian population worldwide,unseasonal sharp fall in air temperature as result of global climate change may also affect the survival and stability of amphibian population *** this article,we have investigated how temperature fluctuation affected the physiology of giant spiny frog (Paa spinosa).The winter temperatures experienced by wild giant spiny frog in natural winter in the local Mountain of Kaihua in zhejiang Province was monitored,and then replicated in subsequent *** frogs were divided into two groups,one group served as a control maintained at 22℃, a second group of frogs were subjected to a temperature fluctuation of cold shock(4℃/12h)and recovery(22℃/12h)for seven *** frogs were sampled after 4h,12h cold shock,12 h recovery at first day and after 12h cold shock,12h recovery at seventh *** results showed that the survival temperature range of wild overwintering was between 0℃-14℃in 12/1/2009-3/31/2010,and minimum and maximum temperature ranged between 0℃-4℃and 10℃-14℃respectively. Upon temperature fluctuation,no statistically significant differences were found in the control groups of all parameters at any time of the *** respiratory burst of spleen macrophages and the peripheral blood phagocytic activity were both inhibited after cold shock,and restored to control level after recovery at 22℃at the first day,and remained the level after temperature fluctuation for seven *** gastric lysozyme activity and the relative hsp70 intensity showed similar results except significant decrease in comparison to that of the control group at the seventh *** malonaldehyde (MDA)content,the glutathione(GSH)content and the activity of superoxide dismutase(SOD)of liver were significantly increased after cold shock for 4h,and th

Bi-directional translocation and degradation of Arginine (Arg) along the arbuscular mycorrhizal (AM) fungal mycelium were testified through 15N and/or 13C isotopic labeling. In vitro mycorrhizas of Glomus intraradices and Ri T-DNA-transformed carrot roots were grown in dual compartment Petri dishes. [15N- and/or13C]Arg was supplied to either the fungal compartment or the mycorrhizal compartment or separate dishes containing the uncolonized roots. The levels and labeling of free amino acids (AAs) in the mycorrhizal roots and in the extraradical mycelia(ERM) were measured by gas chromatogra- phy/mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC). The ERM of AM fungi exposed in either NH4+ or urea as sole external nitrogen source had much higher 15N enrichment of Arg, compared with those in nitrate or exogenous Arg; however, glycerol supplied as an external car- bon source to the ERM had no significant effect on the level of Arg in the ERM. Meanwhile, Arg bio- synthesized in the ERM could be translocated intact to the mycorrhizal roots and thereby the level of Arg in the mycorrhizal roots increased to about 20% after culture of ERM in 4 mmol/L NH4+ for 6 weeks. Also Arg was found to be bi-directionally transported along the AM fungal mycelium through [U-13C]Arg labeling either in the mycorrhizal compartment or in the fungal compartment. Once Arg was translo- cated to the potential N-limited sites, it would be further degraded into ornithine (Orn) and urea since either [U-13C] or [U-15N/U-13C]Orn was apparently shown up in the mycorrhizal root tissues when [U-13C] or [U-15N/U-13C]Arg was labeled in the fungal compartment, respectively. Evidently Orn formation indi- cated the ongoing activities of Arg translocation and degradation through the urea cycle in AM fungal mycelium.

Homoclinic bifurcations in four-dimensional vector fields are investigated by setting up a local coordinate near a homoclinic orbit. This homoclinic orbit is principal but its stable and unstable foliations take inclination flip. The existence, nonexistence, and uniqueness of the 1-homoclinic orbit and 1-periodic orbit are studied. The existence of the two-fold 1-periodic orbit and three-fold 1 -periodic orbit are also obtained. It is indicated that the number of periodic orbits bifurcated from this kind of homoclinic orbits depends heavily on the strength of the inclination flip.

关键词： bifurcation, homoclinic orbit, non-resonance, inclination flip, 1-periodic orbit.

Chiral monodentate phosphoramidite ligands were conveniently prepared from 1,1＇-bi-2-naphthol （BINOL） and （S）-pyrrolidine in good yields, which were effective chiral ligands in the enantioselective rhodium-catalyzed hydrogenation of dehydroamino esters and enamides at low hydrogenation pressure. High conversion rate （up to 99% for dehydroamino esters and enamides） and good enantioselectivity （up to 96.3% ee for dehy- droamino esters and 91.7% ee for enamides） were obtained.
