Composite service provision in mobile ad hoc networks encounters great challenges and its success rate is not satisfactory because the nodes' locations are dynamic and the nodes maybe unavailable at any time.Composite service is built through the service composition.In mobile ad hoc networks,the factors influencing the success rate of service composition are mainly the number of nodes and the time spent for the composition.The node's failure probability is proportional to the length of time the node exist in the networks.In order to improve the success rate of service composition,we take several measures.First,we split the service requirement into several segments and cluster the nodes,so that the nodes' waiting time for service composition can be reduced.Second,we propose a new node model of "one node contains multiple services" in mobile ad hoc networks.Using this type of nodes model,the number of nodes required for service composition can be reduced.These means can increase the success rate of service composition. 展开更多

AIM: To evaluate immunological protection of nitric ox- ide (NO) in hepatopulmonary syndrome and probable mechanisms of ischemia-reperfusion (IR) injury in rat liver transplantation, METHODS: Sixty-six healthy male Wistar rats were randomly divided into three groups (11 donor/recipi-ent pairs). In group 11, organ preservation solution was lactated Ringer's solution with heparin 10 000/μL at 4℃. In groups I and 111, the pLeservation solution added, respectively, L-arginine or Ng-L-arginine methyl ester (L-NAME) (1 mmol/L) based on group 11, and recipients were injected with L-arginine or L-NAME (50 mg/kg) in the anhepatic phase. Grafted livers in each group were stored for 6 h and implanted into recipi- ents. Five rats were used for observation of postopera- tive survival in each group. The other six rats in each group were used to obtain tissue samples, and execut- ed at 3 h and 24 h after transplantation. The levels of alanine aminotransferase (ALT), tumor necrosis factor (TNF)-a and NO metabolites (NOx) were detected, and expression of NO synthase, TNF-α and intercellular adhesion molecule 1 (ICAM-1) was examined by tri- phosphopyridine nucleotide diaphorase histochemical and immunohistochemical staining. RESULTS: By supplementing L-arginine to strengthen the NO pathway, a high survival rate was achieved and hepatic function was improved. One-week sur- viral rate of grafted liver recipients in group I was significantly increased (28.8 4±36.6 d ys 4 4±1.7 d, P 〈 0.01) as compared with groups 11 and Ill. Serum levels of ALT in group ] were 2-7 times less than those in groups 11 and 11I (P 〈 0.01). The cyclic guanosine monophosphate (cGMP) levels in liver tissue and NOx in group I were 3-4 times higher than those of group 11 after 3 h and 24 h reperfusion, while in group ]]], they were significantly reduced as compared with those in group ]1 (P 〈 0.01). The levels of TNF-(z in group I were significantly lower than in group Ⅱ after 3 h and 24 h reperfusion (P 〈 0.01), while being sig- nificantly higher in group Ⅲ than group Ⅱ (P 〈 0.01). Histopathology revealed more severe tissue damage in graft liver and lung tissues, and a more severe in- flammatory response of the recipient after using NO synthase inhibitor, while the pathological damage to grafted liver and the recipient's lung tissues was signifi-cantly reduced in group I after 3 h and 24 h reperfu- sion. A small amount of constitutive NO synthase (cNOS) was expressed in liver endothelial cells after 6 h cold storage, but there was no expression of inducible NO synthase (iNOS). Expression of cNOS was particularly significant in vascular endothelial cells and liver cells at 3 h and 24 h after reperfusion in group Ⅱ but expres- sion of iNOS and ICAM-1 was low in group I. There was diffuse strong expression of ICAM-1 and TNF-α in group Ⅱ at 3 h after reperfusion. CONCLUSION: The NO/cGMP pathway may be critical in successful organ transplantation, especially in treat- ing hepatopulmonary syndrome during cold IR injury in rat orthotopic liver transplantation. 展开更多

Glucose and other carbohydrates are transported into cells using members of a family of integral membrane glucose transporter (GLUT) molecules. To date 14 members of this family, also called the solute carrier 2A proteins have been identified which are divided on the basis of transport characteristics and sequence similarities into several families (Classes 1 to 3). The expression of these different receptor subtypes varies between different species, tissues and cellular subtypes and each has differential sensitivities to stimuli such as insulin. The liver is a contributor to metabolic carbohydrate homeostasis and is a major site for synthesis, storage and redistribution of carbohydrates. Situations in which the balance of glucose homeostasis is upset such as diabetes or the metabolic syndrome can lead metabolic disturbances that drive chronic organ damage and failure, confirming the importance of understanding the molecular regulation of hepatic glucose homeostasis. There is a considerable literature describing the expression and function of receptors that regulate glucose uptake and release by hepatocytes, the most import cells in glucose regulation and glycogen storage. However there is less appreciation of the roles of GLUTs expressed by non parenchymal cell types within the liver, all of which require carbohydrate to function. A better understanding of the detailed cellular distribution of GLUTs in human liver tissue may shed light on mechanisms underlying disease pathogenesis. This review summarises the available literature on hepatocellular expression of GLUTs in health and disease and highlights areas where further investigation is required. 展开更多

Investigating the microstructures and properties of gradient materials has been regarded as a promising way to accelerate the identification of optimal compositions for applications. Herein, a supergravity method is applied to prepare the graded entropic alloys Al-Zn-Li-Mg-Cu. Through carefully optimizing the experimental conditions, the graded microstructures and hardness values appear after the supergravity technique. The morphology of the alloy significantly changes from the bulk intermetallics to eutectic structures along the supergravity force direction, which results from the crushed and graded aluminum oxide combined with the extremelystrong force. The results show that with this supergravity method, a performance-enhanced alloy can potentially be achieved through the centrifugation in a short time span and thus it paves the way for designing and synthesizing entropic alloys with intriguing properties. 展开更多

Bardet-Biedl syndrome(BBS) is a genetically heterogeneous disorder characterized by retinal dystrophy, polydactyly, obesity,developmental delay, and renal defects. At least 21 candidate BBS-associated genes(BBS1-19, NPHP1, and IFT172) have previously been identified, and all of them play important roles in ciliary function. Here, we collected a BBS pedigree with four members and performed whole-exome sequencing on the proband. The variants were analyzed and evaluated to confirm their pathogenicity. We found compound heterozygous variants(c.1192C>T, p.Q398* and c.1175C>T, p.T392M) in MKKS in both the siblings, and these were likely to be pathogenic variants. We also found a missense variant(c.2029G>C, p.E677Q) in NPHP1 and a missense variant(c.2470C>T, p.R824C) in BBS9 in the proband only, which are variants of uncertain significance. The compound heterozygous variants were probably responsible for the BBS phenotype in this Chinese pedigree and the missense mutations in NPHP1 and BBS9 might contribute to the mutation load. 展开更多

OBJECTIVE: To explore the long-term effects and pain relief mechanism of acupotomy by observing changes in nitric oxide synthase (NOS) and beta-en- dorphin (~3-EP) in the hypothalamus, spinal cord, and peripheral blood of rats with third lumbar ver- tebrae (L3) transverse process syndrome. METHODS: Twenty-eight SD rats were randomly as- signed to normal, model, electroacupuncture (EA), and acupotomy group. The last three groups were put through an operation to emulate L3 transverse process syndrome. Fourteen days after the simulation operation, EA and acupotomy treatments were applied to the respective groups. Fifty-six days afterthe simulation operation, biochemistry tests and enzyme-linked immunosorbent assay were used to measure NOS and 13-EP in the hypothalamus, spinal cord, and peripheral blood. RESULTS: Rats with the simulation operation showed significantly higher levels of NOS and II3-EP in the hypothalamus, spinal cord, and peripheral blood than those in the normal group. The EA and acupotomy groups had significantly lower levels of NOS and β-EP than those in the model group. There was no statistical difference between the EA and acupotomy groups. CONCLUSION: EA and acupotomy treatments significantly lowered NOS and β-EP levels in the hypothalamus, spinal cord, and peripheral blood and alleviated L3 transverse process syndrome. 展开更多
