| 1 | 运输应激猪骨骼肌中热应激蛋白HSP_(70)和HSP_(90)家族的表达显示文摘利用Westernblot技术 ,检测长途运输试验猪骨骼肌 (背最长肌和臀大肌 )中分属于HSP70 家族和HSP90 家族的 4种应激蛋白 (HSP70 ,HSP72 ,HSP86和HSP90 )的表达。所有运输应激猪和对照猪肌肉组织中均检测到了上述 4种HSP。对照猪组织中HSP的表达说明HSP除了在受应激的细胞内行使生理功能外 ,还具有独立于应激刺激应答以外的其它作用。6h的长途运输后 ,HSP的表达量明显不同 ,HSP70 和HSP72 在肌肉组织中的表达虽然有一定的增加 ,但统计学分析差异不显著 (P >0 0 5 ) ;而HSP86和HSP90 在骨骼肌中的表达明显下降 ,尤以HSP90 下降最为显著 (P <0 0 1)。提示HSP90 家族成员与肉品品质相关 。 | 鲍恩东 K R Sultan B Nowak J Hartung | 2001 | 南京农业大学学报2001,24,1: | 21 |
| 2 | 温度和光照对3种雀麦属(Bromus)植物种子萌发的影响显示文摘旱雀麦(Bromus tectorum)原产于欧亚大陆,18世纪传入北美,并成为该地区的入侵植物。然而,同为雀麦属的扁穗雀麦(Bromus catharticus)和无芒雀麦(Bromus inermis)并不具有旱雀麦的入侵性。本研究设置高温、低温和黑暗等处理,探讨温度和光照对3种植物种子萌发的影响,旨在从种子萌发的角度揭示旱雀麦的入侵性。结果表明:温度和光照对旱雀麦和扁穗雀麦种子的发芽率均无明显影响(p>0.05);高温和黑暗处理显著提高了无芒雀麦种子的发芽率(p<0.05),对旱雀麦、扁穗雀麦和无芒雀麦种子的发芽势、发芽指数、日均发芽率、发芽系数、发芽峰值和发芽值有一定的促进作用,而低温处理则表现出相反的效应;高温和黑暗处理对3种植物种子的平均发芽天数和萌发持续时间有一定降低的作用,而低温处理则表现出相反的效应。同一处理下旱雀麦种子萌发各项指标均优于另两种植物,这可能是旱雀麦具有较强入侵性的重要原因。 | 周志彬 张元明 ROBERT S.

| 3 | 运输应激猪肝脏中热应激蛋白的定位与表达显示文摘利用免疫组织化学定位方法和Westernblot技术 ,对长途运输试验猪肝脏中 5种不同分子量的热应激蛋白HSP70 、HSP72 、HSP86、HSP90 和HSP2 7进行定位和表达。所有长途运输后应激猪和对照猪肝脏组织中均同时检测到了上述 5种HSP。肝细胞胞浆和胞核均显示阳性信号 ,但HSPs在肝细胞中的定位有差异 ,大多数HSP70 、HSP72 和HSP2 7主要分布于肝细胞胞浆内 ,而HSP90 和HSP86阳性颗粒在核内的分布比其在胞浆中的分布更为明显。肝小叶周边区有明显颗粒变性和脂肪变性的肝细胞中HSPs的阳性染色信号较弱。 6h的长途运输应激后 ,与对照组相比 ,HSPs在肝脏组织中的表达量存在差异 ,表现为HSP70 家族的HSP70 和HSP72 的表达没有明显的升高 (P >0 .0 5 ) ,HSP90 家族的HSP90 的表达出现极显著的增加 (P <0 .0 1) ,然而 ,HSP90 家族的HSP86和小分子量家族的HSP2 7的表达量呈现明显的下降 (P <0 .0 5 )。 | 鲍恩东 Sultan K R Nowak B Hartung J | 2002 | 中国农业科学2002,35,9: | 13 |
| 4 | Microstructure evolution and mechanical properties of Ti-B-N coatings deposited by plasma-enhanced chemical vapor deposition显示文摘Ternary Ti-B-N coatings were synthesized on AISI 304 and Si wafer by plasma-enhanced chemical vapor deposition (PECVD) technique using a gaseous mixture of TiCl4,BCl3,H2,N2,and Ar.By virtue of X-ray diffraction analysis,X-ray photoelectron spectroscopy,scanning electron microscope,and high-resolution transmission electron microscope,the influences of B content on the microstructure and properties of Ti B N coatings were investigated systematically.The results indicated that the microstructure and mechanical properties of Ti-B-N coatings largely depend on the transformation from FCC-TiN phase to HCP-TiB2 phase.With increasing B content and decreasing N content in the coatings,the coating microstructure evolves gradually from FCC-TiN/a-BN to HCP-TiB2 /a-BN via FCC-TiN+HCP-TiB2/a-BN.The highest microhardness of about 34 GPa is achieved,which corresponds to the nanocomposite Ti-63%B-N (mole fraction) coating consisting of the HCP-TiB2 nano-crystallites and amorphous BN phase.The lowest friction-coefficient was observed for the nanocomposite Ti-41%B-N (mole fraction) coating consisting of the FCC-TiN nanocrystallites and amorphous BN | Jung Ho SHIN Kwang Soo CHOI Tie-gang WANG Kwang Ho KIM Roman NOWAK | 2012 | 中国有色金属学会会刊:英文版2012,22,S3: | 13 |
| 5 | Synthesis and properties of Cr-Al-Si-N films deposited by hybrid coating system with high power impulse magnetron sputtering (HIPIMS) and DC pulse sputtering显示文摘The CrN and Cr-Al-Si-N films were deposited on Si wafer and SUS 304 substrates by a hybrid coating system with high power impulse magnetron sputtering (HIPIMS) and a DC pulse sputtering using Cr and AlSi targets under N2/Ar atmosphere.By varying the sputtering current of the AlSi target in the range of 0-2.5 A,both the Al and Si contents in the films increased gradually from 0 to 19.1% and 11.1% (mole fraction),respectively.The influences of the AlSi cathode DC pulse current on the microstructure,phase constituents,mechanical properties,and oxidation behaviors of the Cr-Al-Si-N films were investigated systematically.The results indicate that the as-deposited Cr-Al-Si-N films possess the typical nanocomposite structure,namely the face centered cubic (Cr,Al)N nano-crystallites are embedded in the amorphous Si3N4 matrix.With increasing the Al and Si contents,the hardness of the film first increases from 20.8 GPa for the CrN film to the peak value of 29.4 GPa for the Cr0.23Al0.14Si0.07 N film,and then decreases gradually.In the meanwhile,the Cr0.23Al0.14Si0.07N film also possesses excellent high-temperature oxidation resistance that is much better than that of the CrN film at 900 or 1000 °C. | Min Su KANG Tie-gang WANG Jung Ho SHIN Roman NOWAK Kwang Ho KIM | 2012 | 中国有色金属学会会刊:英文版2012,22,S3: | 11 |
| 6 | Impact of fecal incontinence on quality of life显示文摘AIM:To explore the impact of fecal incontinence (FI) on quality of life (QOL) of patients attending urogynecology and colorectal clinics (CCs).METHODS:Cross-sectional study of 154 patients (27 male) with FI,who attended the clinics at a regional hospital in North Queensland,Australia in 2003 and 2004,and completed the Fecal Incontinence Quality of Life Scale (FIQL:1=very affected;4=not affected).RESULTS:More than 22% of patients had their QOL affected severely by FI.Patients reported that they had not previously been asked about FI by a medical practitioner nor did they voluntarily disclose its presence.The median FIQL scores for all participants were:lifestyle=3.24;coping=2.23;depression=2.42;and embarrassment=2.33.Increasing frequency of soiling had a negative effect on all four FIQL scales (P < 0.001) as did the quantity of soiling (P < 0.01).Female CC patients had poorer FIQL scores than urogynecology clinic patients for lifestyle (P=0.015),coping (P=0.004) and embarrassment (P=0.009),but not depression (P=0.062),despite having experienced FI for a shorter period.CONCLUSION:Failure to seek treatment for FI degrades the quality of patients' lives over time.FI assessment tools should incorporate the quantity of fecal loss. | Lynne Bartlett Madeleine Nowak Yik-Hong Ho | 2009 | World Journal of Gastroenterology2009,15,26: | 10 |
| 7 | Endosonography with linear array instead of endoscopic retrograde cholangiography as the diagnostic tool in patients with moderate suspicion of common bile duct stones显示文摘AIM: To evaluate the diagnostic efficiency of endoscopic ultrasound (EUS) as the main imaging modality in patients with moderate suspicion of common bile duct stones (CBDS).METHODS: 55 patients with moderate clinical suspicion of CBDS were prospectively included to the study and evaluated with EUS. This study was done in single blind method in the clinical and biochemical data of patients. EUS was done with echo-endoscope Pentax FG 32-UA (f=5-7,5 MHz) and Hitachi EUB 405 ultrasound machine. Patients diagnosed with CBDS by EUS were excluded from this study and treated with ERC. All the other patients were included to the follow up study obtained by mail every 6 months for clinical evaluation (need of ERC or surgery).RESULTS: CBDS was found in 4 patients by EUS. Diagnosis was confirmed in all cases on ERC. The remaining 51 patients without CBDS on EUS were followed up for 6-26 months (meanly 13 months) There were: 40 women, 42cholecystectomized patients, aged: 55 (mean). Biochemical values (mean values) were as follows: bilirubin: 14,9 μmol.L-1,alkaline phosphatase: 95 IU.L-,1 γ-GTP: 131 IU.L-1, ALT: 50IU.L-1, AST: 49 IU.L-1, Only 1 patient was lost for follow up.In the remaining 50 patients with follow up, there was only 1 (2 %) patient with persistent biliary symptoms in whom CBDS was finally diagnosed by ERC with ES. All other patients remained symptoms free on follow up and did not require ERC or biliary surgery.CONCLUSION: Vast majority of patients with moderate suspicion of CBDS and no stones on EUS with linear array can avoid invasive evaluation of biliary tree with ERC. | Maciej Kohut Andrzej Nowak Ewa Nowakowska-Dufawa Tomasz Marek Roman Kaczor | 2003 | World Journal of Gastroenterology2003,9,3: | 7 |
| 8 | Application of Nanocrystalline LaNi_5-type Hydrogen Absorbing Alloys in Ni-MH_x Batteries显示文摘The structure and electrochemical properties of nanocrystalline LaNi5-type alloys were studied. These materials were prepared by mechanical alloying (MA) followed by annealing. The properties of hydrogen host materials can be modified substantially by alloying to obtain the desired storage characteristics. It was found that the partial substitution of Ni by Al or Mn in LaNi5-xMx alloy leads to an increase in discharge capacity. The alloying elements such as Al, Mn and Co greatly improved the cycle life of LaNi5 material. For example, in the nanocrystalline LaNi3.75Mn0.75Al0.25Co0.25 powder, discharge capacity up to 258 mAh·g-1 was measured (at 40 mA·g-1 discharge current). Furthermore, the effect of the graphite coating on the structure of some nanocrystalline alloys and the electrodes characteristics were investigated. The mechanical coating with graphite effectively reduced the degradation rate of the studied electrode materials. The combination of a nanocrystalline LaNi5-type hydride electrodes and a nickel positive electrode to form a Ni-MH battery, was successful. | Jurczyk M Nowak M | 2004 | Journal of Rare Earths2004,22,5: | 5 |
| 9 | Evaluating the management of anaphylaxis in US emergency departments:Guidelines vs.practice显示文摘BACKGROUND:Anaphylaxis is characterized by acute episodes of potentially life-threatening symptoms that are often treated in the emergency setting.Current guidelines recommend:1) quick diagnosis using standard criteria;2) first-line treatment with epinephrine;and 3) discharge with a prescription for an epinephrine auto-injector,written instructions regarding long-term management,and a referral(preferably,allergy) for follow-up.However,studies suggest low concordance with guideline recommendations by emergency medicine(EM) providers.The study aimed to evaluate how emergency departments(EDs) in the United States(US) manage anaphylaxis in relation to guideline recommendations.METHODS:This was an online anonymous survey of a random sample of EM health providers in US EDs.RESULTS:Data analysis included 207 EM providers.For respondent EDs,approximately 9%reported using agreed-upon clinical criteria to diagnose anaphylaxis;42%reported administering epinephrine in the ED for most anaphylaxis episodes;and <50%provided patients with a prescription for an epinephrine auto-injector and/or an allergist referral on discharge.Most provided some written materials,and follow-up with a primary care clinician was recommended.CONCLUSIONS:This is the first cross-sectional survey to provide 'real-world' data showing that practice in US EDs is discordant with current guideline recommendations for the diagnosis,treatment,and follow-up of patients with anaphylaxis.The primary gaps are low(or no) utilization of standard criteria for defining anaphylaxis and inconsistent use of epinephrine.Prospective research is recommended. | W.Scott Russell Judith Rosen Farrar Richard Nowak Daniel P.Hays Natalie Schmitz Joseph Wood Judi Miller | 2013 | World Journal of Emergency Medicine2013,4,2: | 4 |

| 11 | Docosahexaenoic acid suppresses arachidonic acid-induced proliferation of LS-174T human colon carcinoma cells显示文摘AIM:To investigate the impact of arachidonic acid (AA) and docosahexaenoic acid (DHA) and their combination on colon cancer cell growth.METHODS:The LS-174T colon cancer cell line was used to study the role of the prostaglandin precursor AA and the omega-3 polyunsaturated fatty acid DHA on cell growth. Cell viability was assessed in XTT assays. For analysis of cell cycle and cell death,flow cytometry and DAPI staining were applied. Expression of cyclooxygenase-2 (COX-2),p21 and bcl-2 in cells incubated with AA or DHA was examined by real-time RT-PCR. Prostaglandin E2 (PGE2) generation in the presence of AA and DHA was measured using a PGE2-ELISA.RESULTS:AA increased cell growth,whereas DHAreduced viability of LS 174T cells in a time-and dose-dependent manner. Furthermore,DHA down-regulated mRNA of bcl-2 and up-regulated p21. Interestingly,DHA was able to suppress AA-induced cell proliferation and significantly lowered AA-derived PGE2 formation. DHA also down-regulated COX-2 expression. In addition to the effect on PGE2 formation,DHA directly reduced PGE2-induced cell proliferation in a dose-dependent manner. CONCLUSION:These results suggest that DHA can inhibit the pro-proliferative effect of abundant AA or PGE2. | Piet Habbel Karsten H Weylandt Katja Lichopoj Johannes Nowak Martin Purschke Jing-Dong Wang Cheng-Wei He Daniel C Baumgart Jing X Kang | 2009 | World Journal of Gastroenterology2009,15,9: | 2 |

| 16 | Comparison of the prognostic value of frailty assessment tools in patients aged≥65 years hospitalized in a cardiac care unit with acute coronary syndrome显示文摘BACKGROUND Frailty is associated with adverse events in elderly patients with acute coronary syndrome(ACS).Our aim was to compare the prognostic value of four frailty scales in patients aged≥65 years hospitalized with ACS in a cardiac care unit(CCU).METHODS Patients aged≥65 years with ACS were included.Frailty was assessed using the Fried frailty scale(reference standard),the Edmonton Frail Scale(EFS),the FRAIL scale,and the Clinical frailty scale(CFS).The primary end point was all-cause mortality and the secondary end point was unscheduled rehospitalization.RESULTS One hundred and seventy four patients aged≥65 years with ACS were recruited.The median follow-up was 637.5 days.Frailty was identified in 41.4%,40.2%,39.1%and 36.3%patients by the Fried frailty scale,EFS,FRAIL scale and CFS,re-spectively.The agreement coefficients were 0.88,0.86,and 0.79 for the FRAIL scale,EFS and CFS,respectively.In the Cox regres-sion model,frailty was associated with all-cause mortality regardless of the scale used(univariate:hazard ratio[HR]95%CI=10.5,2.4-46.8 Fried frailty scale;12.0,2.7-53.4 FRAIL scale;7.1,2.0-25.2 EFS;8.3,2.4-29.6 CFS.Multivariate:HR=5.1,1.1-23.8 Fried frailty scale;5.7,1.2-26.8 FRAIL scale;3.7,1.0-14.0 EFS;4.2,1.1-15.9 CFS).The FRAIL scale had the highest HR.In the uni-variate analysis,frailty was associated with unscheduled rehospitalization(HR=3.2,1.7-6.0 Fried frailty scale;3.4,1.8-6.3 FRAIL scale;3.5,1.8-6.6 EFS;3.1,1.7-5.8 CFS).In the multivariate analysis,only the EFS independently predicted unscheduled rehospit-alization(HR=2.2,1.1-4.63).CONCLUSIONS Frailty assessed by the Fried frailty scale,FRAIL scale,EFS and CFS is associated with all-cause mortality and unscheduled rehospitalization in elderly patients hospitalized in a CCU with ACS.The adjusted HR of the FRAIL scale for all-cause mortality was the highest among the scales compared,whereas the EFS was an independent predictor of unscheduled re-hospitalization.These data should be taken into consideration when choosing a frailty assessment tool. | Wojciech Nowak Ilona Kowalik Małgorzata Kuzin Agnieszka Krauze Anna Mierzyńska Ewa Sadowy Kamil Marcinkiewicz Janina Stępińska | 2022 | Journal of Geriatric Cardiology2022,19,5: | 2 |
