In the last two decades the anterior cingulate cortex (ACC) has become one of the most investigated areas of the brain. Extensive neuroimaging evidence suggests countless functions for this region, ranging from conflict and error coding, to social cognition, pain and effortful control. In response to this burgeoning amount of data, a proliferation of computational models has tried to characterize the neurocognitive architecture of ACC. Early seminal models provided a computational explanation for a relatively circumscribed set of empirical findings, mainly accounting for EEG and fMRI evidence...

Although eucalypts are the most planted hardwood trees worldwide, the majority of them are frost sensitive. The recent creation of frost-tolerant hybrids such as Eucalyptus gundal plants (E. gunnii × E. dalrympleana hybrids), now enables the development of industrial plantations in northern countries. Our objective was to evaluate the impact of cold on the wood structure and composition of these hybrids, and on the biosynthetic and regulatory processes controlling their secondary cell-wall (SCW) formation...

REVIEW
Hitoshi Okazawa
PQBP1 (polyglutamine binding protein-1) is the earliest identified molecule among the group of disease-related intrinsically disordered/denatured proteins. PQBP1 interacts with splicing-related factors via the disordered/denatured domain and regulates post-transcriptional gene expression. The mutations cause intellectual disability due to decreased dendritic spines and abnormal expression of synapse molecules in neurons, and microcephaly due to elongated cell cycle time and abnormal expression of cell cycle proteins in neural stem progenitor cells...

KRAS proto-oncogene, GTPase (KRAS) remains refractory to current therapies. We devised an integrative cross-tumor approach to expose common core elements up-regulated in mutant KRAS cancers that could provide new treatment opportunities. This approach identified FOSL1 (Fos-like antigen 1) as a clinically and functionally relevant gene in mutant KRAS-driven lung and pancreatic cancers, and unveiled downstream transcriptional targets amenable to pharmacological inhibition.

BACKGROUND: The Philippine archipelago is globally one of the most important model island systems for studying evolutionary processes. However, most plant species on this archipelago have not yet been studied in sufficient detail. The main aim of this study is to unravel the evolutionary history and biogeographic relationships of the Philippine members of the pantropical genus Ixora. RESULTS: The complex plastid and nuclear divergence patterns in Philippine Ixora, documented using tree and network approaches, reveal a highly dynamic evolution in Ixora, involving several phases of radiation and recolonization...

Mitochondria are dynamic organelles whose morphology and activity are extremely variable, depending on the metabolic state of the cell. In particular, their shape and movements within the cell are finely regulated by an increasing number of proteins, which take part in the process of mitochondrial fission/fusion and connect the organelles to the cytoskeleton. As to their activities, mitochondria are considered to be at the crossroad between cell life and death since, on the one hand, they are essential in ATP production and in multiple metabolic pathways but, on the other, they are involved in the intrinsic apoptotic cascade, triggered by different stress conditions...

In this issue of Developmental Cell, Jossin et al. (2017) show that the tumor suppressor protein Lgl1 interacts with N-cadherin to stabilize apical junctions in brain stem cells. Neural progenitors lacking Lgl1 had decreased N-cadherin internalization and abnormal cell junctions, generating an ectopic neuronal layer that resembles cerebral cortex abnormalities in humans.

Lipotoxicity can mediate endothelial dysfunction in obesity. Altered endothelial cell phenotype during the pathobiological course of the lipotoxicity may lead to the hemostatic abnormalities, which is a hallmark of several hematological disorders. Impaired hemostasis could also be directly related to the numerous metabolic diseases such as hypertension, diabetes and atherosclerosis. On the other hand, local hematopoietic bone marrow (BM) renin-angiotensin system (RAS) contributes to the development of atherosclerosis via acting on the lipotoxicity processes...

Traditionally, research in anti-doping has been stimulated by the need for technological improvements to accommodate the expansion of the list of prohibited substances and methods. Nevertheless, in recent years, anti-doping found itself at a crossroads due to the increasing complexity and constant refinement of doping methods. As illustrated by the 2012 USADA (United States Anti-Doping Agency) versus Lance Armstrong case, a change in paradigm was necessary. The exploration of new scientific avenues to understand the mechanisms of doping and pinpoint its practice was most needed to allow designing more efficient preventive or disruptive strategies...

Over the last years, many actions have been implemented in the Canadian province of Quebec to prevent health issues related to diet, physical activity and obesity. As a new public health programme is being launched, the 'How can we do better?' project aimed to identify priority areas for further action. An exhaustive search led to identify 166 interventions rolled out in Quebec between 2006 and 2014. We compared it with evidence-based recommendations. Findings were challenged during a 2-d deliberative forum gathering 25 key stakeholders...

Limited information is available on suitable height of transport crates for turkeys. We compared behaviors and physiological indicators of four groups of 10 female turkeys each confined in either conventional (38.5 cm height) or experimental (77 cm height) crates during six commercial pre-slaughter transportations for 86 km (76 ± 4 min) along two tracts with one-lane streets, crossroads, bends, roundabouts (S1 and S2) and a highway tract (H) between S1 and S2. Only 36% of birds in the higher crates maintained a standing position...

Aging represents the major risk factor for cancer. Cancer and aging are characterized by a similar dysregulated metabolism consisting in upregulation of glycolysis and downmodulation of oxidative phosphorylation. In this respect, metabolic interventions can be viewed as promising strategies to promote longevity and to prevent or delay age-related disorders including cancer. In this review, we discuss the most promising metabolic approaches including chronic calorie restriction, periodic fasting/fasting-mimicking diets, and pharmacological interventions mimicking calorie restriction...

During the past decade, knowledge of pathogen life history has greatly benefited from the advent and development of molecular epidemiology. This branch of epidemiology uses information on pathogen variation at the molecular level to gain insights into a pathogen's niche and evolution and to characterize pathogen dispersal within and between host populations. Here, we review molecular epidemiology approaches that have been developed to trace plant virus dispersal in landscapes. In particular, we highlight how virus molecular epidemiology, nourished with powerful sequencing technologies, can provide novel insights at the crossroads between the blooming fields of landscape genetics, phylogeography, and evolutionary epidemiology...
