In eukaryotes, ribosome assembly is a highly complex process that involves more than 200 assembly factors that ensure the folding, modification and processing of the different rRNA species as well as the timely association of ribosomal proteins. One of these factors, Mpp10 associates with Imp3 and Imp4 to form a complex that is essential for the normal production of the 18S rRNA. Here we report the crystal structure of a complex between Imp4 and a short helical element of Mpp10 to a resolution of 1.88 Å. Furthermore, we extend the interaction network of Mpp10 and characterize two novel interactions...

The innate alarm system (IAS), comprised of functionally connected brain regions including the brainstem, amygdala, pulvinar, and frontotemporal cortex, is a fast subcortical brain network facilitating rapid responses to threat. Post-traumatic stress disorder (PTSD) features subconscious and conscious threat detection, together contributing to hyperarousal symptoms. Emerging literature identifies aberrant threat-related neurocircuitry involved in subconscious and conscious threat processing in PTSD. We review this literature, focusing on subconscious threat processing and its relation to the IAS...

REVIEW
Ruth Feldman, Marian J Bakermans-Kranenburg
In non-human mammals mothering is hormone-dependent, with crucial roles for oxytocin and prolactin. While human parenting is not hormone-dependent, hormonal changes in oxytocin, vasopressin, prolactin, testosterone, and cortisol prime and accompany the expression of parenting. In the following we focus on oxytocin (OT) as a key hormone in human parenting. OT is a nine-amino-acid neuropeptide hormone which evolved from the ancient vasotocin molecule approximately 650 MYO. OT is implicated in sociality across vertebrate evolution and substantial research has pinpointed its role in birth, lactation, and maternal care in mammals...

REVIEW
Alice W Y Leung, Ruth S M Chan, Mandy M M Sea, Jean Woo
This review aims to provide an overview of the factors associated with adherence reported in existing literature on lifestyle modification programs for weight management among the adult population. An electronic search was performed using PubMed, Medline, PsycINFO and PsycARTICLE to identify studies that examined the factors of adherence to lifestyle modification programs with explicit definition of adherence indicators. We identified 19 studies published between 2004 and 2016. The most commonly used indicator of adherence was attrition, followed by attendance, self-monitoring and dietary adherence...

Neural crest cells are both highly migratory and significant to vertebrate organogenesis. However, the signals that regulate neural crest cell migration remain unclear. In this study, we test the function of differential screening-selected gene aberrant in neuroblastoma (DAN), a bone morphogenetic protein (BMP) antagonist we detected by analysis of the chick cranial mesoderm. Our analysis shows that, before neural crest cell exit from the hindbrain, DAN is expressed in the mesoderm, and then it becomes absent along cell migratory pathways...

Incorporation of biomolecular epitopes to malarial antigens should be explored in the development of strain-transcending malarial vaccines. The present study sought to determine safety, immunogenicity and cross-species efficacy ofPlasmodium falciparum serine repeat antigen 5 polypeptide co-expressed with epitopes of Bacille-Calmette Guerin (BCG), tetanus toxoid (TT) and a chemokine gene. Olive baboons and BALB/c mice were randomly assigned into vaccine and control groups. The vaccine group animals were primed and boosted twice with pIRES plasmids encoding the SERA5+ BCG+ TT alone, or with either CCL5 or CCL20 and the control group with pIRES plasmid vector backbone...

Triple-negative breast cancers (TNBC) are highly aggressive, lack FDA-approved targeted therapies, and frequently recur, making the discovery of novel therapeutic targets for this disease imperative. Our previous analysis of the molecular mechanisms of action of Bromodomain and extraterminal protein inhibitors (BETi) in TNBC revealed these drugs cause multinucleation, indicating BET proteins are essential for efficient mitosis and cytokinesis. Here, using live cell imaging, we show that BET inhibition prolonged mitotic progression and induced mitotic cell death, both of which are indicative of mitotic catastrophe...

BACKGROUND: Metabolic syndrome (MS) is a well-known risk factor for the development of cardiovascular (CV) disease; yet, controversy persists whether it adds incremental prognostic value in patients with established CV disease. OBJECTIVES: This study was performed to determine if MS is associated with worse CV outcomes in patients with established CV disease treated intensively with statins. METHODS: We performed a post hoc analysis of the Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes trial, in which patients with established CV disease and atherogenic dyslipidemia (n = 3414) were randomly assigned to receive extended release niacin or placebo during a mean 36-month follow-up, to assess whether the presence of MS or the number of MS components contributed to CV outcomes...

We present 3 cases of patients with castration-resistant prostate cancer and bone metastases treated with Ra, belonging to our prospective and multicenter ChoPET-Rad study. All patients underwent clinical, hematological, and biochemical monitoring between each Ra administration. Initial and follow-up F-fluorocholine PET/CT and Tc-biphosphonate bone scintigraphy were performed previously and after the third Ra administration. Both techniques correctly established the response to treatment, in agreement to the biochemical response, although differences in the disease expression (concordant and discordant patterns) were found because of the different radiotracer biodistribution and molecular information derived from them...

BACKGROUND: Medical personnel working in intensive care often face difficult ethical dilemmas. These may represent important sources of distress and may lead to a diminished self-perceived quality of care and eventually to burnout. AIMS OF THE STUDY: The aim of this study was to identify work-related sources of distress and to assess symptoms of burnout among physicians and nurses working in Swiss neonatal intensive care units (NICUs). METHODS: In summer 2015, we conducted an anonymous online survey comprising 140 questions about difficult ethical decisions concerning extremely preterm infants...

Reduction in low-density lipoprotein cholesterol (LDL-C) is associated with decreased risk for cardiovascular disease. Alirocumab, an antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9), significantly reduces LDL-C. Here, we report development of a quantitative systems pharmacology (QSP) model integrating peripheral and liver cholesterol metabolism, as well as PCSK9 function, to examine the mechanisms of action of alirocumab and other lipid-lowering therapies, including statins. The model predicts changes in LDL-C and other lipids that are consistent with effects observed in clinical trials of single or combined treatments of alirocumab and other treatments...

#19
REVIEW
Benjamin Wolfe, Jonathan Dobres, Ruth Rosenholtz, Bryan Reimer
Applied research on driving and basic vision research have held similar views on central, fovea-based vision as the core of visual perception. In applied work, the concept of the Useful Field, as determined by the Useful Field of View (UFOV) test, divides vision between a "useful" region towards the center of the visual field, and the rest of the visual field. While compelling, this dichotomization is at odds with findings in vision science which demonstrate the capabilities of peripheral vision. In this paper, we examine driving research from this new perspective, and argue for the need for an updated understanding of how drivers acquire information about their operating environment using peripheral vision...
