question:
Inter-tissue molecular interactions are critical to the function and behavior of biological systems in multicellular organisms, but systematic studies of interactions between tissues are lacking. Also, existing studies of inter-tissue interactions are based on direct gene expression correlations, which can't distinguish correlations due to common genetic architectures versus biochemical or molecular signal exchange between tissues.", 'We developed a novel strategy to study inter-tissue interaction by removing effects of genetic regulation of gene expression (genetic decorrelation). We applied our method to the comprehensive atlas of gene expression across nine human tissues in the Genotype-Tissue Expression (GTEx) project to generate novel genetically decorrelated inter-tissue networks. From this we derived modules of genes important in inter-tissue interactions that are likely driven by biological signal exchange instead of their common genetic basis. Importantly we highlighted communication between tissues and elucidated gene activities in one tissue inducing gene expression changes in others.', 'We reveal global unidirectional inter-tissue coordination of specific biological pathways such as protein synthesis. Using our data, we highlighted a clinically relevant example whereby heart expression of DPP4 was coordinated with a gene expression signature characteristic for whole blood proliferation, potentially impacting peripheral stem cell mobilization. We also showed that expression of the poorly characterized FOCAD in heart correlated with protein biosynthetic processes in the lung.

question:
Arteriovenous fistulas (AVFs) are commonly used during hemodialysis. Early failure of AVFs is quite common with incidence of 43% to 63%. In this study we aimed to describe a novel approach to AVF surgery for improving early patency rates.', 'Patients were divided into two groups according to use of probing and warm-wash-out technique. Group I consisted of 31 patients with additional probing technique. Group II consisted of 32 patients without additional maneuver. End-to-side anastomosis were used to all patients. Technical success was defined as having palpation of a thrill on fistula. Flow rates of draining vein was measured at 1st hour, 24th hour, 1st week and 3rd week of surgery.', 'Classical maneuvers were performed until end of the anastomosis. At this time, vein lumen was washed by low-dosed heparinized warm fluid, with assistance of a simple catheter.', 'Technical success was similar in both groups at 1st hour and 24th hour, while there were significantly differences between groups at 1st week (p = 0.042) and 3rd week (p = 0.05) assessments. Flow rates were also measured significantly higher in Group I at 1st hour (p = 0.011) and 24th hour (p = 0.016). Flow rates were almost similar in two groups at 1st and 3rd weeks but overall success rate was higher in Group I comparing with Group II (96.8% vs. 81.3%, respectively, p = 0.05).

question:
Intestinal ischemia-reperfusion (II/R) induced acute lung injury is mediated by activated neutrophils and formation of free radicals. Several antioxidants have been shown to attenuate such remote organ injury. We studied the effects of zinc aspartate on lung injury induced by II/R in rats.', 'Twenty-four Sprague-Dawley rats were randomized into three groups. Group I was the control. Animals in Groups II and III (II/R + zinc aspartate [ZA]) underwent 60 min of ischemia and 60 min of reperfusion, respectively. Rats in Group III also received 50 mg/kg zinc aspartate before 15 min of reperfusion. Lung tissue samples and bronchoalveolar lavage fluid were obtained to assess lung tissue myeloperoxidase (MPO), adenosine deaminase (ADA), xanthine oxidase (XO), glutathione peroxidase (GPx) activities, and nitric oxide (NO), malondialdehyde (MDA) levels. Also, the levels of MDA, NO, and MPO activity were determined in bronchoalveolar lavage fluid.', 'Compared with the control, lung tissue MDA, NO levels, and MPO, ADA, XO activities were markedly increased (P < 0.05), whereas GPx activity significantly decreased in the II/R group (P < 0.05). However, administration of ZA significantly reversed these effects by reducing the levels of MDA, NO, and decreasing MPO, ADA, XO activities (P < 0.05). In addition, ZA significantly increased GPx activity (P < 0.05). The activity of MPO and the levels of NO and MDA were found to be higher in bronchoalveolar lavage fluid in II/R group than the control (P < 0.05). Zinc aspartate significantly diminished MPO activity and the levels of NO and MDA compared with that of control rats (P < 0.05).
