BACKGROUnD: Controversy exists over whether living donor liver transplantation (LDLT) should be offered to patients with high Model for End-stage Liver Disease (MELD) scores. This study tried to determine whether a high MELD score would result in inferior outcomes of right-lobe LDLT. METHODS: Among 411 consecutive patients who received right-lobe LDLT at our center, 143 were included in this study. The patients were divided into two groups according to their MELD scores: a high-score group (MELD score ≥25; n=75) and a low-score group (MELD score n=68). Their demographic data and perioperative conditions were compared. Univariable and multivariable analyses were performed to identify risk factors affecting patient survival. RESULTS: In the high-score group, more patients required preoperative intensive care unit admission (49.3% vs 2.9%; Pnical ventilation (21.3% vs 0%; Png time before LDLT was shorter (4 vs 66 days; Pnsfused during operation (7 vs 2 units; Pnts stayed longer in the intensive care unit (6 vs 3 days; Pnd hospital (21 vs 15 days; P=0.015) after transplantation;more patients developed early postoperative complications (69.3% vs 50.0%; P=0.018); and values of postoperative peak blood parameters were higher. However, the two groups had comparable hospital mortality. Graft survival and patient overall survival at one year (94.7% vs 95.6%; 95.9% vs 96.9%), three years (91.9% vs 92.6%; 93.2% vs 95.3%), and five years (90.2% vs 90.2%; 93.2% vs 95.3%) were also similar between the groups. COnCLUSIOnS: Although the high-score group had signifi-cantly more early postoperative complications, the two groups had comparable hospital mortality and similar satisfactory rates of graft survival and patient overall survival. Therefore, a high MELD score should not be a contraindication to right-lobe LDLT if donor risk and recipi

Purification and Some Properties of Endo-1,4-β-Glucanases of Trichoderma harzianum UzCF-28

引用

Open Journal of Applied Sciences 2016年第8期6卷 514-523页

作者： n. sh. Azimova D. M. Khamidov M. B. Djumagulov Z. S. shakirov Institute of Microbiology of Uzbekistan Academy of Sciences Tashkent Republic of Uzbekistan

This work aimed at isolation, purification and study of biochemical features of cellulolytic enzymes synthesized by Trichoderma harzianum UzCF-28 strain. Strain UzCF-28 revealed a high cellulolytic activity during submerged cultivation in the liquid culture on modified Mandels nutrient medium, where wheat straw was used as a source of carbon. As a result of purification by precipitation with ammonium sulfate and further ion exchange chromatography, two isoforms of endo- 1,4-β-glucanase-EG II and EG III with molecular weight of 135 and 75 kDa respectively were revealed. The pH optimum for EG I and EG III was 4.5, while for EG II—4.7, irrespective of the applied substrates—either CMC or “Whatman filter” paper. Heating up to 40°C of EG III did not lead to its inactivation, and on the contrary, its activity increased by more than three times comparing to the initial activity of the enzyme, i.e. thermostability of EG III among tested enzymes significantly varied.

Reducing problem of multiplication operators on Bergman space

Chinese Science Bulletin 1997年第1期42卷 83-83页

作者： Yu, DH Sun, sh Department of Mathematics Sichuan University Chengdu China

THE L_a^2(D) refers to Bergman space on D, where D is the unit disk on the complex plane. Using the super-isometric dilation technique, we obtain the following results. Proposition 1. The multiplication operator M_φ on Bergman space L_a^2 (D) is unitarily equivalent to the compression of the direct sum of 2n-1 copies of Bergman shift, where φ is a Blaschke product of order n (<∞).
