Gut microbiota and its metabolites may be protective or detrimental in liver diseases. Scientific discoveries regarding this complex role have benefited millions of patients in the past two decades. Famous examples are the leverages of short-chain fatty acids and bile acids to cure or mitigate many prevalent liver diseases. Recently, we have witnessed more and more ongoing and to-start studies to find the links between gut microbiota and gut/liver diseases. In addition, there are an increasing number of studies exploring the disruption of gut microbiome by food/environmental contaminants. Also, positive manipulation of gut microbiota using natural products has become a hot spot due to their potential usage in food and clinical aspects. In this regard, we are organizing this Research Topic to gather relevant advances and findings. It is already known that gut microbiota's functional and compositional changes are associated with liver diseases. The problem remains unclear on which specific gut microbiota changes are indicative of particular liver and gut diseases. For example, a high abundance of Prevotella or Veillonella in the distal intestine is observed in cirrhosis patients; an increased abundance of Lactobacillus and decreased abundance of Clostridium are observed both in patients with Metabolic Associated Fatty Liver Disease. Also, there are many factors that may cause the changes of featured gut-microbes which can interact with host. Roseburia can crosstalk with host intestinal epithelial immune cells by secreting butyrate that binds to TLR5 and SP3 signaling and then repairs the host epithelium lesion. By contrast, dietary exposure to mycotoxin aflatoxin b1 has been found to reduce the Roseburia significantly in mice and rat models. Green tea polyphenols were found to restore the abundance of Roseburia. As the above scientific issues are being explored by global scientists, it is time to call for a Research Topic in the field to gather novel findings and new progress. We believe this collection will enhance the basis for future gut-microbiota research and will surely have more patients benefit from relevant research. This Research Topic welcomes Original Research Articles, Reviews and Mini-reviews, Opinions, Perspectives and Methods. The manuscripts are suggested to be within the following scopes but not limited to: (1) Recently discovered change of gut-microbiome patterns corresponding to particular liver diseases. (2) Novel findings in terms of gut-microbiota-dependent metabolites or metabolic pathways that contribute to the incidence and mitigation of liver diseases. (3) Characterization of specific interaction or crosstalk between gut-microbiome species/family with host liver system. (4) Changes of gut-microbiota induced by xenobiotics (antibiotics; probiotics; food contaminants; natural products) and potential links with the incidence and mitigation of liver diseases. (5) Clinical or food application of natural products to manipulate gut microbiota as an alternative medicine to treat liver diseases.

Chemotherapy is one of the major treatment options for cancer patients; however, the efficacy of chemotherapeutic management of cancer is severely limited by multidrug resistance, in that cancer cells become simultaneously resistant to many structurally and mechanistically unrelated drugs. In the past three decades, a number of mechanisms by which cancer cells acquire multidrug resistance have been discovered. In addition, the development of agents or strategies to overcome resistance has been the subject of intense study. This book contains comprehensive and up-to-date reviews of multidrug resistance mechanisms, from over-expression of ATP-binding cassette drug transporters such as P-glycoprotein, multidrug resistance-associated proteins, and breast cancer resistance p- tein to the drug ratio-dependent antagonism and the paradigm of cancer stem cells. The book also includes strategies to overcome multidrug resistance, from the development of compounds that inhibit drug transporter function to the modulation of transporter expression. In addition, this book contains techniques for the detection and imaging of drug transporters, methods for the investigation of drug resistance in animal models, and strategies to evaluate the efficacy of resistance reversal agents. The book intends to provide a state-of-the-art collection of reviews and methods for both basic and clinician investigators who are interested in cancer multidrug resistance mechanisms and reversal strategies.

Over the past few decades, extensive research has been conducted on the applications of agricultural robots and automation to a variety of field and greenhouse operations, and technical fundamentals and their feasibility have also been widely demonstrated. Due to the unstructured environment, adverse interference and complicated and diversified operation process are the key of blocking its commercialization in robotic agricultural operations. Because of the development of automation techniques, smart sensors, and information techniques, some types of agricultural robots have achieved considerable success in recent years. This book intends to provide the reader with a comprehensive overview of the current state of the art in agricultural robots, fundamentals, and applications in robotic agricultural operations.
