Loss of Responsiveness to Osmotic Stress in Maize Root:the Effect of Water Channel Blocker HgCl_2

引用

Agricultural Sciences in China 2010年第8期9卷 1230-1235页

作者： ZHU Jian-jun BAI xin-fu zhang Ping WANG Yan-hua College of Life Sciences Ludong University Yantai 264025 P.R.China

In order to investigate the effect of water channel blocker HgCl2 on the hydraulic resistance in roots of maize seedlings, a xylem pressure probe was used to monitor the changes in root xylem pressure in response to NaCl- or mannitol-induced osmotic stresses before and after the application of HgCl2. When the maize roots were subjected to 500 umol L-1 HgCl2 in root bathing solution, not only a considerable decline in xylem pressure （increase in xylem tension） was observed, but the loss of responsiveness of the plant to both salt- and mannitol-induced osmotic stresses in terms of xylem pressure change was seen as well when the transpiration rate of the plant was not significantly changed. The results are similar but different from the reversed osmosis by the Fenton reaction in the internodes of Chara coralline, showing that the mechanisms of water transport across cell membrane in plant roots are far more complicated than expected.

AIM To evaluate the curative effect of pylorus and pyloric vagus-preserving gastrectomy (PPVPG) on peptic *** Treating 132 cases of GU and DU with PPVPG, and comparative studies made with 24 cases treated with Billroth Ⅰ (BⅠ) and 20 cases with Billroth Ⅱ (BⅡ); advantages and shortcomings *** Not a single death after PPVPG. No recurrence of the disorder in the subsequent follow-up for an average of 6.5 years. Curative effect (visik Ⅰ & Ⅱ) 97.7%. Acidity reduction similar to that found in BⅠ and BⅡ, but 97.7% of the BⅠ and all BⅡ cases having more than second degree intestinal fluid reflux, in contrast to 7.1% in PPVPG cases. Dumping syndrome occurred in the BⅠ and BⅡ cases, none in PPVPG cases. With regard to gastric emptying, food digestion, absorption, body weight and life quality, PPVPG proved to be superior to Billroth *** PPVPG has the advantages of conventional Billroth gastrectomy in reducing acid, removing ulcer focus, and at the same time preserves the pylorus and pyloric vagus for maintaining the normal gastric physiological function. Dumping syndrome, intestinal fluid reflux and other complications of conventional gastrectomy may be avoided.

A comparative study of buccal mucosa graft and penile pedical flap for reconstruction of anterior urethral strictures

引用

Chinese Medical Journal 2010年第3期123卷 365-368页

作者： SA Ying-long XU Yue-min QIAN Yong JIN San-bo fu Qiang zhang xin-ru zhang Jiong GU Bao-jun Department of Urology Shanghai 6th People's Hospital Affiliated to Shanghai Jiao Tong University Shanghai 200233 China

Anterior urethral strictures, where the length is more kthan 2 cm, are best treated by substitution urethroplasty with either preputial/penile skin flaps or free grafts.1 The use of dartos pedicled flaps has many advantages in terms of increased survival thanks to its own vascularization. Recently, buccal mucosa has become increasingly popular among urologists for urethral replacement when local penile skin is unavailable. Both penile skin flaps and buccal mucosa grafts have emerged as reliable urethral substitutes with comparable long-term results. These urethral substitutes are traditionally placed on the ventral aspect of the stricture and have a success rate of about 85%.

The unavoidable dendrite growth and shuttle effect have long been stranglehold challenges limiting the safety and practicality of lithium-sulfur ***,we propose a dual-action strategy to address the lithium dendrite issue in stages by constructing a multifunctional surface-negatively-charged nanodiamond layer with high ductility and robust puncture resistance on polypropylene （PP） *** uniformly loaded compact negative layer can not only significantly enhance electron transmission efficiency and promote uniform lithium deposition,but also reduce the formation of dendrite during early deposition *** importantly,under the strong puncture stress encountered during the deterioration of lithium dendrite growth under limiting current,the high ductility and robust puncture resistance（145.88 MPa） of as-obtained nanodiamond layer can effectively prevent short circuits caused by unavoidable lithium *** Li||Li symmetrical cells assembled with nanodiamond layer modified PP demonstrated a stable cycle of over 1000 h at 2 mA cm-2with a polarization voltage of only 29.3 ***,the negative charged layer serves as a physical barrier blocking lithium polysulfide ions,effectively mitigating capacity *** improved cells achieved a capacity decay of only 0.042%per cycle after 700 cycles at 3 C,demonstrating effective suppression of dendrite growth and capacity attenuation,showing promising prospect.
