This study aim. to investigate the effect of sodium.replacem.nt on the quality characteristics of past?rm.. For this purpose, past?rm. production with four different salt m.xtures(Ⅰ. 100% Na Cl; Ⅱ. 50% Na Cl + 50% KCl; Ⅲ. 40% NaCl + 40% KCl + 20% CaCl2; Ⅳ. 30% NaCl + 40% KCl + 20% CaCl2+ 10% m.Cl2) were carried out using traditional m.thod. The use of different salt m.xtures for past?rm. had no statistically significant effect on the m.crobial counts and residual nitrite of the final product. The a* and b* values were affected by this treatm.nt. The salt m.xture containing CaCl2or CaCl2+ m.Cl2significantly decreased the p H values and sensory scores. The eighteen volatile com.ounds were affected by the salt m.xtures. Na~+, K~+, Ca2+, and m.2+had a certain increase depending on their ratio in the salt m.xtures. The highest Cathepsin activity in all past?rm. sam.les was observed in Cathepsin B + L. The salt m.xture with NaCl + KCl + CaCl2+ m. Cl2increased acid lipase activity. However, this m.xture had no significant effect on neutral lipase activity.

In this study, it has been investigated that the incorporation of poly(ethylene glycol) and 4-styrenesulfonic acid sodium salt into acrylamide hydrogel during free radical solution polymerization synthesis for novel highly swollen adsorbents and for the effective removal of some potential pollutants from aqueous solutions such as cationic dyes. Poly(ethylene glycol)diacrylate was used as a multifunctional crosslinker. The main purpose of this study was to combine both monomers and a polymer in a new polymeric system. Dye sorption properties of the polymeric hydrogels were investigated by using cationic dye such as Janus Green B. Swelling and sorption studies were carried out at 25°C. For structural characterization, FT-IR analysis and SEM studies were applied. To determine the sorption behaviors of Janus Green B, some sorption parameters such as dye removal capacity, adsorption percentage, and partition coefficient of the polymeric hydrogels were investigated.

Nuclear Science and Techniques 2012年第2期23卷 75-82页

作者： YAN Han ZHAO Lei LIU Shubin CHEN kat WU Weihao AN Qi LENG Yongbin YI Xing YAN Yingbing LAI Longwei State Key Laboratory of Particle Detection&Electronics University of Science and technology of ChinaHefei230026China Anhui Key Laboratory of Physical Electronics Department of Modern PhysicsUniversity of Science and technology of ChinaHefei230026China Shanghai Institute of Applied Physics Chinese Academy of SciencesShanghai201800China

This fully digital beam.position m.asurem.nt instrum.nt is designed for beam.position m.nitoring and m.chine research in Shanghai Synchrotron Radiation Facility. The signals received from.four position-sensitive detectors are narrow pulses with a repetition rate up to 499.654 m.z and a pulse width of around 100 ps, and their dynam.c range could vary over m.re than 40 dB in m.chine research. By the em.loym.nt of the under-sam.ling technique based on high-speed high-resolution A/D conversion, all the processing procedure is perform.d fully by the digital signal processing algorithm. integrated in one single Field Program.able Gate Array. This system.functions well in the laboratory and com.issioning tests, dem.nstrating a position resolution (at the turn by turn rate of 694 kHz) better than 7 μm.over the input am.litude range of -40 dBm.to 10 dBm.which is well beyond the requirem.nt.

Testicular fine-needle aspiration for the assessm.n＇ of intratesticular horm.ne concentrations

Asian Journal of Andrology 2016年第1期18卷 21-24页

作者： Ada P Lee m.ra Y Roth Jean-Jacques Nya-Ngatchou kat Lin Thom.s J Walsh Stephanie T Page Alvin m.m.tsum.to William.J Brem.er John K Am.ry Bradley D Anawalt Departm.nt of m.dicine University of California San Francisco San Francisco CA USA Departm.nt of m.dicine and Center for Research in Reproduction and Contraception University of Washington Seattle WA USA Departm.nt of Obstetrics and Gynecology University of Washington Seattle WA USA Departm.nt of Urology University of Washington Seattle WA USA Departm.nt of m.dicine Geriatric Research Education and Clinical Center VA Puget Sound Health Care System Seattle WA USA.

m.asurem.nt of intratesticular sex steroid concentrations in m.n inform. both the developm.nt of m.le horm.nal contraceptives and the understanding of m.le infertility. Given the challenges of using invasive techniques to m.asure testicular horm.ne physiology, our group has used a m.nim.lly-invasive fine-needle aspiration technique to m.asure intratesticular horm.nes in norm.l healthy m.n. Herein, we present a post-hoc analysis of the safety and efficacy of testicular fine-needle aspiration （FNA） com.leted as part of six clinical trials. From.2001 through 2011, a total of 404 procedures were conducted am.ng 163 research volunteers, 85.9% of which were successful in obtaining sufficient fluid for the m.asurem.nt of intratesticular steroid concentrations. Pain was the m.st com.on side effect, with 36.8% of procedures associated with m.derate procedural pain and 4.7% with severe procedural pain. Postprocedural pain was uncom.on and abated within a few days. m.ld local bruising occurred with 14.9% of procedures. Two serious adverse events （0.5%） required surgical intervention. The risk of an adverse event was not associated with age, body m.ss index, testicular size, or the volum. of fluid aspirated. Testicular FNA to obtain fluid for m.asurem.nt of intratesticular steroid concentrations frequently causes m.ld to m.derate procedural pain, but serious adverse events occur rarely. Testicular FNA has been instrum.ntal for defining hum.n intratesticular horm.ne physiology and is a m.nim.lly-invasive, safe, effective m.thod for obtaining fluid for research on testicular physiology and pathology.
