The ripening of climacteric fruits,such as apple,is represented by a series of genetically programmed events orchestrated by the action of several hormones.In this study,we investigated the existence of a hormonal crosstalk between ethylene and auxin during the post-harvest ripening of three internationally known apple cultivars:‘Golden Delicious',‘Granny Smith'and‘Fuji'.The normal climacteric ripening was impaired by the exogenous application of 1-methylcyclopropene(1-MCP)that affected the production of ethylene and the physiological behaviour of specific ethylene-related quality traits,such as fruit texture and the production of volatile organic compounds.The application of 1-MCP induced,moreover,a de-novo accumulation of auxin.The RNA-Seq wide-transcriptome analysis evidenced as the competition at the level of the ethylene receptors induced a cultivar-dependent transcriptional re-programming.The DEGs annotation carried out through the KEGG database identified as most genes were assigned to the plant hormone signaling transduction category,and specifically related to auxin and ethylene.The interplay between these two hormones was further assessed through a candidate gene analysis that highlighted a specific activation of GH3 and ILL genes,encoding key steps in the process of the auxin homeostasis mechanism.Our results showed that a compromised ethylene metabolism at the onset of the climacteric ripening in apple can stimulate,in a cultivar-dependent fashion,an initial de-novo synthesis and de-conjugation of auxin as a tentative to restore a normal ripening progression.

A novel framework for non-Manhattan channel routing considering crosstalk and wire length reduction is proposed. To handle crosstalk and wire length reduction problem, an improved non-Manhattan router in the gridded routing model is developed, and a novel rerouting algorithm based on segment-rerouting technique and layer reassignment is presented. Simulation exDeriments demonstrate that our algorithm achieves verv good results.

Objective: To describe the relationship between autophagy and apoptosis and the possible signaling pathways involved in degenerative lumbar intervertebral disc. Summary of Background Data: Autophagy and apoptosis are regulatory cellular mechanisms that determine many pathologies, including degenerative intervertebral disc disease. The interactions between these events in the damage or protection of intervertebral disc cells and in cellular homeostasis remain controversial. Methods: The sample size was twenty patients who underwent lumbar spine surgery for symptomatic disc herniation or spondylolisthesis. Intervertebral discs were classified by magnetic resonance as Pfirrmann grade IV and grade V. Six patients were operated on two levels, resulting in twenty-six intervertebral discs that were submitted to immunohistochemistry to verify the protein expression of autophagy and apoptosis markers. Results: The autophagic markers had greater protein expression in the human intervertebral disc (Pfirrmann Grades IV and V). Under these conditions, autophagy and apoptosis showed a negative correlation. Regarding apoptosis, caspase 8 presented the highest protein expression, which allows inferring the preference for the extrinsic pathway in cell death. Conclusions: Autophagy had the greatest protein expression negative profile compared to apoptosis. Caspase 8 had the highest protein expression in apoptosis.

The existence of parasitical parameters,such as coupling inductances and coupling capacitance between wires,makes crosstalk inevitable. In order to investigate the effect of crosstalk,accurately and efficiently computing of parasitical parameters is needed. In this paper,Partial element equivalent circuit （PEEC） method is used to partition the model of wires and ground plane,to extract the partial parameters of resistances,capacitances and inductances forming the equivalent SPICE circuit and to analyze the effect of crosstalk. Different kinds of relative position of wires are considered.

The effect of queuing delay of output buffer on the crosstalk property in optical packet switching nodes is investigated. The relationship between crosstalk and buffer length is obtained. From the calculation and simulation results, it is concluded that the crosstalk power penalty predominantly depends on the buffer length, the longer the buffer, the greater the penalty, as well as the random range of the penalty. While comparing with the effect of queuing delay, the effect of random routing path delay takes very little proportion in the total power penalty.

The factors that determine fibrosis progression or normal tissue repair are largely unknown.We previously demonstrated that autophagy inhibition-mediated epithelial-mesenchymal transition(EMT)in human alveolar epithelial type Il(ATIl)cells augments local myofibroblast differentiation in pulmonary fibrosis by paracrine signaling.Here,we report that liver kinase B1(LKB1)inactivation in ATIl cells inhibits autophagy and induces EMT as a conse-quence.In IPF lungs,this is caused by the down-regulation of CAB39L,a key subunit within the LKB1 complex.3D co-cultures of ATIl cells and MRC5 lung fibroblasts coupled with RNA sequencing(RNA-seq)confirmed that paracrine signaling between LKB1-depleted ATIl cells and fibroblasts augmented myofibroblast differentiation.Together,these data suggest that reduced autophagy caused by LKB1 inhibition can induce EMT in ATIl cells and contribute to fibrosis via aberrant epithelial-fibroblast crosstalk.

The relationship between the intestines and their microbiota,the liver,and the neuronal system is called the gutliver-brain axis.This relationship has been studied and observed for a relatively short time but is considered in the development of research focused on,e.g.,liver diseases and intestinal dysbiosis.The role of the gut microbiota in this relationship is crucial,as it acts on poultry’s performance and feed utilization,affecting meat and egg quality.The correct composition of the intestinal microbiota makes it possible to determine the essential metabolic pathways and biological processes of the individual components of the microbiota,allowing further speculation of the role of microbial populations on internal organs such as the liver and brain in the organism.The gut microbiota forms a complex,dense axis with the autonomic and enteric nervous systems.The symbiotic relationship between the liver and gut microbiota is based on immune,metabolic and neuroendocrine regulation,and stabilization.On the other hand,the gut-brain axis is a bidirectional interaction and information transfer system between the gastrointestinal tract and the central nervous system.The following paper will discuss the current state of knowledge of the gut-liver-brain axis of poultry,including factors that may affect this complex relationship.
