The cystic fibrosis microbiome in an ecological perspective and its impact in antibiotic therapy

The recent focus on the cystic fibrosis (CF) complex microbiome has led to the recognition that the microbes can interact between them and with the host immune system, affecting the disease progression and treatment routes. Although the main focus remains on the interactions between traditional pathogens, growing evidence supports the contribution and the role of emergent species. Understanding the mechanisms and the biological effects involved in polymicrobial interactions may be the key to improve effective therapies and also to define new strategies for disease control. This review focuses on the interactions between microbe-microbe and host-microbe, from an ecological point of view, discussing their impact on CF disease progression. There are increasing indications that these interactions impact the success of antimicrobial therapy. Consequently, a new approach where therapy is personalized to patients by taking into account their individual CF microbiome is suggested.Portuguese Foundation for Science and Technology (FCT), the strategic funding of UID/BIO/04469/2013-CEB and UID/EQU/00511/2013-LEPABE units.

Genome Sequencing, Transcriptomics, and Proteomics

This review encompasses the current status of major areas of progress in olive tree genome sequencing, including insights into genome function derived from large-scale gene expressing profiling, and studies on genomic architecture of repetitive sequences, smaller RNA, and proteomics. Olive tree genomics, as well as other omics, is progressing owing to recent developments in next-generation sequencing (NGS) technologies. Biological insights, therefore, are not only resulted from the sequencing initiative, since from genetic mapping, gene expression profiling, gene discovery research, and proteomics over nearly last seven years a large amount of information has been provided by different laboratories. The availability of highquality genome assembly provides olive biologists with valuable new tools to improve and develop new varieties more efficiently, enabling the implementation of marker-assisted selection and genomic selection, and contributing to the comprehension of the molecular determinants of key traits peculiar to the species of olive tree and giving important clues concerning the evolution of its complex genome

The hippocampus and memory: insights from spatial processing

The hippocampus appears to be crucial for long-term episodic memory, yet its precise role remains elusive. Electrophysiological studies in rodents offer a useful starting point for developing models of hippocampal processing in the spatial domain. Here we review one such model that points to an essential role for the hippocampus in the construction of mental images. We explain how this neural-level mechanistic account addresses some of the current controversies in the field, such as the role of the hippocampus in imagery and short-term memory, and discuss its broader implications for the neural bases of episodic memory
