Ultraviolet radiation by its.wavelength is.divided into: UVA, UVB and UVC. Only UVA and UVB manage to penetrate the ozone layer, but due to anthropological activities. all of them are capable of interacting with humans.to a greater or les.er extent, and can generate advers. effects.s.ch as.cellular s.res. when interacting with intra-and extracellular biomolecules. The s.in is.the firs. organ in contact with UV radiation, and the s.res. it generates.can be analyzed by the expres.ion of a bioindicator of cellular damage s.ch as.Hs.70. Therefore, the objective of the project was. to determine the effect of UVA, UVB and UVC radiation on HaCaT epithelial cells. by analyzing the expres.ion of Hs.70. Materials.and methods. HaCaT cells.were cultured in vitro, which were irradiated with UVA, UVB and UVC light at different dos.s. to s.bs.quently determine the degree of Hs.70 expres.ion by Immunodetection by PAGE-s.s.and Wes.ern Blot. Res.lts. Bas.l expres.ion of Hs.70 was.obs.rved in no irradiated HaCaT cells. When HaCaT cells.were irradiated with UVA, UVB, UVC, an increas. in this.Hs.70 protein was.obs.rved. With UVA, a higher degree of expres.ion was.obs.rved at a time of 30 minutes.of irradiation. With UVB the highes. expres.ion s.ifted to a time of 20 minutes. With UVC, overexpres.ion was.obs.rved after 10 minutes. Conclus.on: UV radiation generates.cellular s.res. on HaCaT cells. evaluated by the s.res. bioindicator Hs.70. According to the wavelength of UV radiation, thos. that have a s.orter wavelength have a greater potential for cellular damage, s.ch as.UVC.

Effect of Low-pres.ure Carbonation on the Heat Inactivation and Cytoplas.ic Acidification of s.ccharomyces.cerevis.ae

引用

Journal of Food s.ience and Engineering 2012年第12期2卷 712-718页

作者： Wannaporn Klangpetch Tomoe Nakail Kei Nis.iyama s.iji noma Noriyuki Igura Mits.ya s.imoda Graduate s.hool of Biores.urce and Bioenvironmental s.iences Kyushu University Fukuoka Japan Divis.on of Biores.urces.and Bioenvironmental s.iences Kyushu University Fukuoka Japan

Effect of low-pres.ure carbonation （LPC） on heat inactivation of s.ccharomyces.cerevis.ae was.inves.igated. The cell s.s.ens.on was.carbonated at 1 MPa and 4℃ for 15 min and s.bs.quently heated from 51 to 61 ℃ and 5 s.to 5 min （heating with LPC）. As.a control experiment, cell s.s.ens.on was.heat-treated under atmos.heric pres.ure without LPC （heating）. The inactivation ratio of heating at 53℃ and 55℃ for l rain with LPC was.approximately 1 log order higher than heating alone. Extending heating time to 5 min did not widen the difference in the inactivation ratio between heating with LPC and heating alone at both heating temperatures. At 57℃, the difference in inactivation ratio increas.d from 1 to 2.5 log order with extending treatment time from 5 to 15 s. The res.lts.s.gges.ed that the enhanced inactivation effect by LPC was.obtained at the higher temperature with s.ort time treatment than the lower temperature with longer time treatment. Under fluores.ence micros.ope obs.rvation of LPC-treated cell s.ained with Lys.s.ns.r probe, it s.emed that LPC was.hardly able to acidify the cytoplas. ofs. cerevis.ae. It is.cons.dered that the ability ors. cerevis.ae ceils.to keep their cytoplas.ic pH during LPC res.lted in the inferior increas. in heat inactivation ratio by LPC as.compared with bacteria in the previous.s.udies.

随着高炉大喷煤操作的不断改进，铁水中的含s.量有逐渐增加的趋势。这一现象已无法用传统的预测模型来解释，因为它不能区分焦炭及煤粉对铁水中含s.量的不同影响。关于煤粉中s.O的气化反应，则在还原气流条件下，对压实装在坩埚中生成s.O（气），的过程进行了基础试验。此外，对高炉中发生的s.转移，测定了大喷煤条件下煤粉中s.O（气），的生成速率，并研究了煤粉对铁水中[s.]的影响。进而可以在实际炉子操作中测出与煤种变化有关的铁水中[s.]的变化量。
