AIM To systematically review reports on deceased-donor-lobar lung transplantation(dd LLTx) and uniformly describe sizematching using the donor-to-recipient predicted-total lung-capacity(pT LC) ratio. METHODS We set out to systematically review reports on ddL LTx and uniformly describe size matching using the donorto-recipient pT LC ratio and to summarize reported oneyear survival data of ddL LTx and conventional-LTx. We searched in Pub Med, CINAHL via EBSCO, Cochrane Database of Systematic Reviews via Wiley(CDSR),Database of Abstracts of Reviews of Effects via Wiley(DARE), Cochrane Central Register of Controlled Trials via Wiley(CENTRAL), Scopus(which includes EMBASE abstracts), and Web of Science for original reports on ddL LTx. RESULTS Nine observational cohort studies reporting on 301 ddL LTx met our inclusion criteria for systematic review of size matching, and eight for describing one-year-survival. The dd LLTx-group was often characterized by high acuity;however there was heterogeneity in transplant indications and pre-operative characteristics between studies. Data to calculate the pT LC ratio was available for 242 ddL LTx(80%). The mean pT LCratio before lobar resection was1.25 ± 0.3 and the transplanted pT LCratio after lobar resection was 0.76 ± 0.2. One-year survival in the ddL LTxgroup ranged from 50%-100%, compared to 72%-88%in the conventional-LTx group. In the largest study ddL LTx(n = 138) was associated with a lower one-year-survival compared to conventional-LTx(n = 539)(65.1% vs84.1%, P < 0.001). CONCLUSION Further investigations of optimal donor-to-recipient size matching parameters for ddL LTx could improve outcomes of this important surgical option.

Corrosion behavior of tempered dual-phase steel embedded in concrete

引用

International Journal of Minerals,Metallurgy and Materials 2009年第1期16卷 43-50页

作者： Oguzhan Kelestemur Mustafa Aksoy servet Ylldlz Department of Construction Education Firat University Department of Metallurgy and Materials Engineering Firat University

Dual-phase （DP） steels with different martensite contents were obtained by appropriate heat treatment of an SAE1010 structural carbon steel, which was cheap and widely used in the construction industry. The corrosion behavior of DP steels in concrete was investigated under various tempering conditions. Intercritical annealing heat treatment was applied to the reinforcing steel to obtain DP steels with different contents of martensite. These DP steels were tempered at 200, 300, and 400℃ for 45 min and then cooled to room temperature. Corrosion experiments were conducted in two stages. In the first stage, the corrosion potential of DP steels embedded in concrete was measured every day for a period of 30 d based on the ASTM C 876 standard. In the second stage, the anodic and cathodic polarization values of these steels were obtained and subsequently the corrosion currents were determined with the aid of cathodic polarization curves. It was observed that the amount of second phase had a definite effect on the corrosion behavior of the DP steel embedded in concrete. As a result of this study, it is found that the corrosion rate of the DP steel increases with an increase in the amount of martensite.

Safety and efficacy of trimodality therapy in patients undergoing extrapleural pneumonectomy

引用

Chinese Journal of Cancer Research 2013年第2期25卷 130-131页

作者： servet Blükbas Department of Thoracic Surgery Dr.-Horst-Schmidt-KlinikLudwig-Erhard-Strasse 100 65199 Wiesbaden Germany

Malignant pleural mesothelioma （MPM） is a rare but rapidly deadly disease （1）. Macroscopic complete resection （MCR） is the goal of surgery （2）. MCR seems to have the most significant impact on survival in patients undergoing multimodality treatment for MPM. The role of surgical resection in the management of MPM remains controversial. The selection criterion to perform either extrapleural pneumonectomy （EPP） or extended/radical pleurectomy/ decortication （PD） rely not only on the cardio-pulmonary status of the patient, tumor stage and intraoperative findings but is strongly dependent also on surgeons＇ decision and philosophy. This is reflected by a recent survey of opinions and beliefs among 802 thoracic surgeons, in which EPP was believed to be more effective than PD （3）. Nonetheless, either surgery might achieve MCR.

Mono-cropping systems consisting of general low-yielding cereals are crucial productivity constraints in dry areas of the Mediterranean region.A crop rotation consisting of quinoa(Chenopodium quinoa Willd.)-wheat(Triticum aestivum L)-chickpea(Cicer arietinum)was compared with monocropping in the Mediterranean region of Turkey.A four year crop rotation trial was set up in Adana,Turkey.A total of nine crop rotation systems of Quinoa(Q),chickpea(L)and wheat(W)were considered in this *** four year results revealed that there was significant difference in grain and biomass yields,but no significant difference in plant height,harvest index,and 1000 grain weight of wheat among the treatments in crop rotation except number of grains per spike and soil organic *** wheat and chickpea-wheat-chickpea-wheat(LWLW)produced significantly greater grain yield in 2010/2011 and 2011/*** and QWQW rotation produced significantly lower biomass yield in 2008/*** maximum biomass yield of LWLW rotation resulted in 2011/2012 growing ***,the effect of previous crop on wheat grain and biomass yield in the four years of the rotation study was significantly *** the long run,the favorable effects of legume-based rotations on crop yields and water productivity are apparent.
