Background： Three experiments w.re conducted to examine the overall hypothesis that addition of medium chain triglycerides（MCT） and cysteamine hydrochloride（CSH） into the diets of young and grow.ng pigs w.uld stimulate the endogenous somatotropic axis to improve grow.h and ***： In Experiment 1, w.aner pigs w.re given either a 5 d dietary supplement of 5 % MCT（n = 8） or a control diet（n = 8）. MCT increased the plasma concentration of grow.h hormone（GH; P ＆lt; 0.05） and the GH secretagogue,ghrelin（P ＆lt; 0.05）. Additionally, the MCT treatment reduced scouring（P ＆lt; 0.05）, maintained villous height in the small intestine（P ＆lt; 0.05） and stabilised daily w.ight gain（P ＆lt; 0.05）, compared to the controls. Experiment 2compared the effects of 4 levels（0, 1, 3 and 6 % v/v） of MCT supplementation in grow.r-finisher male pigs, of approximately 35 kg live w.ight（n = 15 per treatment）. Blood samples taken after 7 w. of treatment show.d that the MCT supplementation increased circulating ghrelin（P ＆lt; 0.001）, GH（P ＆lt; 0.01） and insulin（P ＆lt; 0.05）concentrations in a dose-dependent manner. Daily w.ight gain, feed intake and feed conversion ratio w.re not affected by the MCT diets. In Experiment 3, 64 female pigs of approximately 60 kg live w.ight w.re allocated to one of three dietary treatments： control（n = 20）; 6 % MCT（n = 21）; and 70 mg/kg CSH（n = 21）. After 3 w. of supplementation, the MCT treated pigs had a higher plasma concentration of ghrelin compared to the control and CSH pigs（P ＆lt; 0.05）. Plasma concentrations of GH and w.ight w.re not affected by any of the dietary ***： Evidence is provided in Experiment 1 to support the use of dietary MCT supplements, perhaps acting via stimulation of somatotropic endocrine pathw.ys, to minimise w.aning-associated disorders such as slow.ng of grow.h and diarrhoea. In Experiments 2 and 3, although there w.s no effect on w.ight gain or feed conversion ratio in either experiment, MCT and CSH incr

MicroRNAs(miRNAs) provide insight into both the biology and clinical behavior of many human cancers, including nasopharyngeal carcinoma(NPC). The dysregulation of miRNAs in NPC results in a variety of tumor-promoting effects. Furthermore, several miRNAs are prognostic markers for NPC. In addition to cellular miRNAs, NPC samples also often contain miRNAs encoded by Epstein-Barr virus, and these miRNAs may impact NPC biology by targeting both cellular and viral genes. Given their numerous putative roles in NPC development and progression, a thorough understanding of the impact of miRNA dysregulation in NPC is expected to shed light on useful biomarkers and therapeutic targets for the clinical management of this disease. In this review. w. describe the efforts to date to identify and characterize such miRNAs in the context of NPC.

The concepts of conditional expectations, martingales and stopping times w.re extended to the Riesz space context by Kuo, Labuschagne and w.tson （Discrete time stochastic processes on Riesz spaces, Indag. Math.,15（2004）, 435-451）. Here w. extend the definition of an asymptotic martingale （amart） to the Riesz spaces context, and prove that Riesz space amarts can be decomposed into the sum of a martingale and an adapted sequence convergent to zero. Consequently an amart convergence theorem is deduced.

AIM: To test the hypothesis that cellular uncoupling induced by myocardial ischemia is mediated by activation of cmitochondrial ATP-sensitive potassium channels (mitoKATP). METHODS: Rat hearts w.re perfused on a Langendorff apparatus and subjected to 40-min ischemia follow.d by 30-min reperfusion (I/R). Changes in cellular coupling w.re monitored by measuring w.0}e-tissue resistance. RESULTS: (1) In hearts subjected to I/R, the onset of uncoupling started at (13.3±1.0) mm of ischemia; (2) Ischemic preconditioning (IPC) delayed the onset of uncoupling until (22.7±1.3) min.

Coal burst is a dynamic release of energy w.thin the rock （or coal） mass leading to high velocity expulsion of the broken/failed material into mine openings. This phenomenon has been recognised as one of the most catastrophic failures associated w.th the coal mining industry, w.ich can often lead to injuries and fatalities of miners as w.ll as significant production losses. This paper aims to examine the mecha- nisms contributing to coal burst occurrence, w.th an emphasis on the energy release concept. In this study, a numerical modelling study has been conducted to evaluate the roles and contributions of differ- ence energy components. The energy analysis presented in this paper can help to improve the under- standing of energy release mechanisms esoeciallv under Australian conditions.

w. investigate the 2- and 3-state ferromagnetic Ports models on the simple cubic lattice using the tensor renorrealization group method w.th higher-order singular value decomposition （FIOTRG）. HOTRG w.rks in the thermodynamic limit, w.ere w. use the Zq symmetry of the model, combined w.th a new.measure for detecting the transition, to improve the accuracy of the critical point for the 2-state model by tw. orders of magnitude, obtaining Tc = 4.51152469（1）. The 3-state model is far more complex, and w. improve the overall understanding of this case by calculating its thermodynamic quantities w.th high accuracy. Our results verify that the first-order nature of the phase transition and the HOTRG transition temperature benchmarks the most recent Monte Carlo result.
