Preparation and Anti-oxidative Effects of Corn Peptides

Corn peptides(CP) were prepared from zein via proteolysis by means of a type of alkaline protease, Alcalase, at 50 ℃ and pH 8.0. The anti oxidative activity of the hydrolysate was examined. It was found that the anti oxidative activity reached the maximum at the fourth hour of the hydrolysis and then decreased. The effect of the enzyme dosage on the solubility of corn protein, the dependence of hydrolysis time on the degree of the hydrolysis(DH) and molecular weight distribution were examined respectively. 30% DH was controlled on the basis of anti oxidative activity. The hydrolysate was fractionated on a Sephadex G 15 column. The anti oxidative activities were examined for all the fractions. The main fraction for anti oxidative activity was collected and characterized by the methods of amino acid analysis, the measurement of average chain length and etc .. The main M W distribution of the main fraction was 300-600 Daltons. The anti oxidative properties of the small peptides in vitro were studied. It was found that they could inhibit the auto oxidation of pyrogallol and the oxidation of hemoglobin. The hemolysis degree of erythrocyte caused by hydroxyl free radicals was decreased greatly, indicating a protective effect of the anti oxidative peptides on the cell membrane damage of erythrocyte.

Cloning,Eukaryotic Expression of Human ISG20 and Preliminary Study on the Effect of Its Anti-HBV

Human ISG20 gene was cloned and the effect of its anti-HBV was primarily studied. The ISG20 gene was amplified from HeLa cells by RT-PCR and recombinant vector expressing ISG20 was constructed by genetic engineering. The overexpression of ISG20 in HepG2 cells was detected by Western blot and the levels of secretion of HBs antigen and HBe antigen tested by ELISA. The results showed that： （1） Sequence of ISG20 cloned was consistent to that published in Genebank; （2） Recombinant vector expressing ISG20 could be expressed in HepG2 cells by transfection; （3） The overexpression of ISG20 protein could reduce the levels of the secretion of HBs antigen and HBe antigen in transfected HepG2 cells. It was suggested that the overexpression of recombinant ISG20 in culture cells could reduce the synthesis of HBV proteins.

Heavy-ion and pulsed-laser single event effects in 130-nm CMOS-based thin/thick gate oxide anti-fuse PROMs

Single event effects of 1-T structure programmable read-only memory(PROM) devices fabricated with a 130-nm complementary metal oxide semiconductorbased thin/thick gate oxide anti-fuse process were investigated using heavy ions and a picosecond pulsed laser. The cross sections of a single event upset(SEU) for radiationhardened PROMs were measured using a linear energy transfer(LET) ranging from 9.2 to 95.6 MeV cm^2mg^(-1).The result indicated that the LET threshold for a dynamic bit upset was ～ 9 MeV cm^2mg^(-1), which was lower than the threshold of ～ 20 MeV cm^2mg^(-1) for an address counter upset owing to the additional triple modular redundancy structure present in the latch. In addition, a slight hard error was observed in the anti-fuse structure when employing209 Bi ions with extremely high LET values(～ 91.6 MeV cm^2mg^(-1)) and large ion fluence(～ 1×10~8 ions cm^(-2)). To identify the detailed sensitive position of a SEU in PROMs, a pulsed laser with a 5-μm beam spot was used to scan the entire surface of the device.This revealed that the upset occurred in the peripheral circuits of the internal power source and I/O pairs rather than in the internal latches and buffers. This was subsequently confirmed by a ^(181)Ta experiment. Based on the experimental data and a rectangular parallelepiped model of the sensitive volume, the space error rates for the used PROMs were calculated using the CRèME-96 prediction tool. The results showed that this type of PROM was suitable for specific space applications, even in the geosynchronous orbit.

AIM: To determine the effect of multiple injections of ranibizumab or bevacizumab on retinal nerve fiber layer (RNFL) and intraocular pressure (IOP) in patients with age-related macular degeneration (AMD). ·METHODS: This retrospective study includes 35 eyes of 35 patients treated with intravitreal bevacizumab (IVB, 1.25mg/0.05mL) and 30 eyes of 30 patients with intravitreal ranibizumab (IVR, 0.5mg/0.05mL) who had Fast RNFL analysis (Stratus TM ); IOP measurements were taken 30 minutes and 24 hours after each injection. RESULTS: The mean ages were 68.0±7.5 and 69.1±7.7 years in the IVR and IVB groups, respectively (P =0.55). They underwent (6.3±1.9) and (5.1±1.3) injections (P = 0.07) over (13.6±2.1) and (14.05±2.6) months (P =0.45) in the IVR and IVB groups, respectively. Changes in overall and temporal RNFL thickness in IVR-treated eyes (105.3± 6.9μm and 74.4±11.2μm) were not different from those in untreated eyes in the IVR group (104.6±8.4μm and 75.1±12.6μm) (P =0.57 and P =0.41, respectively). Similarly, overall and temporal RNFL thickness in IVB-treated eyes (105.8±8.1μm and 74.5±11.8μm) were not different from those in untreated eyes in the IVB group (104.6±8μm and 74.8±12.9μm) (P=0.42 and P=0.80, respectively). The frequencies of IOP rise (P=0.60) and changes in RNFL thickness from baseline (P =0.16) were comparable between groups. CONCLUSION: Repeated intravitreal injection of ranibizumab or bevacizumab does not seem have adverse effects on RNFL thickness or IOP in wet AMD patients.

Anti-viral Effects of Urosolic Acid on Guinea Pig Cytomegalovirus In Vitro

This study examined the anti-viral effect of ursolic acid on guinea pig cytomegalovirus (GPCMV) and explored the steps of viral replication targeted by ursolic acid. Cytopathic effect assay and MTT method were employed to determine the 50% cellular cytotoxicity (CC50), 50% effective concentration (EC50) and therapeutic index (TI) with GPCMV. To investigate the specific anti-viral effect of ursolic acid at different temperatures and time points, two other medicines, ganciclovir and Jinyebaidu (JYBD), serving as controls, were studied for comparison. Our results showed that the CC50 of ganciclovir, JYBD and ursolic acid were 333.8, 3015.6, 86.7 μg/mL, respectively; EC50 of ganciclovir, JYBD and ursolic acid was 48.1, 325.5 and 6.8 μg/mL, respectively; TI of ganciclovir, JYBD and ursolic acid was 7, 9, 13, respectively. Similar with ganciclovir, ursolic acid could inhibit the viral synthesis, but did not affect the viral adsorption onto and penetration into cells. We are led to conclude that the anti-cytomegalovirus effect of ursolic acid is significantly stronger than ganciclovir or JYBD, and the cytotoxic effect of ursolic acid lies in its ability to inhibit viral synthesis.

Studies on Male Antifertilitic and Immunomodulatory Effects of TW19

TW19 is a diterpene compound isolated from the root cortex of Tripterygium Wil- fordii Hood. F.. Its effects on the immune function in ICR mice and the male fertility in SD rats, ICR mice and Kunming mice were evaluated. TW19 was given orally for 5 weeks. Then the antifertilitic effect was assessed by mating test. The results showed that ED50, for anti-fertilitic were 332μg/kg, 369. 9μg/kg and 286. 8 μg/kg per day in SD rats, ICR mice and Kunming mice respectively. After the treatment of TW19 at antifertility dose for 5 weeks consecutively, the spermatozoa density and motility of trial animals reduced significantly, The weight of testic also declined in SD rats and Kunming mice, but no effects were observed in ICR mice. TW19 inhibited prolifera- tion of splenic T and B-lymphocytes of ICR mice in vitro and hence inhibited the anti- body formation in vivo, but compared with T 4, the immunosuppressive effect of TW19 was less obvious.
