REVIEW
Marcella L Woud, Johan Verwoerd, Julie Krans
Cognitive models of Posttraumatic Stress Disorder (PTSD) postulate that cognitive biases in attention, interpretation, and memory represent key factors involved in the onset and maintenance of PTSD. Developments in experimental research demonstrate that it may be possible to manipulate such biases by means of Cognitive Bias Modification (CBM). In the present paper, we summarize studies assessing cognitive biases in posttraumatic stress to serve as a theoretical and methodological background. However, our main aim was to provide an overview of the scientific literature on CBM in (analogue) posttraumatic stress...

REVIEW
Nathan C Rockwell, J Clark Lagarias
Phytochromes control almost every aspect of plant biology, including germination, growth, development, and flowering, in response to red and far-red light. These photoreceptors thus hold considerable promise for engineering crop plant responses to light. Recently, structural research has shed new light on how phytochromes work. Genomic and transcriptomic studies have improved our understanding of phytochrome loss, retention, and diversification during evolution. We are also beginning to understand phytochrome function in cyanobacteria and eukaryotic algae...

Kiril D Hristovski, Jasmina Markovski
To create an integrative foundation for engineering of the next generation inexpensive sorbent systems, this critical review addresses the existing knowledge gap in factor/performance relationships between weak-acid oxyanion contaminants and metal (hydr)oxide sorbents. In-depth understanding of fundamental thermodynamics and kinetics mechanisms, material fabrication, and analytical and characterization techniques, is necessary to engineer sorbent that exhibit high capacity, selectivity, stability, durability and mass transport of contaminants under a wide range of operating and water matrix conditions requirements...

BACKGROUND: There is a need for better joint pain treatment, but development of new medication has not been successful. Pre-clinical models with readouts that better reflect the clinical situation are needed. In patients with joint pain, pain at rest and pain at walking are two major complaints. NEW METHOD: We describe a new way of calculating results from gait analysis using the CatWalk™ setup. Rats with monoarthritis induced by injection of Complete Freund's Adjuvant (CFA) intra-articularly into the ankle joint of one hind limb were used to assess gait and dynamic weight bearing...

The emergence of Zika virus (ZIKV) infection has stimulated several research groups to study and collaborate to understand virus biology and pathogenesis. These efforts may assist with the development of antiviral drugs, vaccines and diagnostic tests, as well as to promote advancements in public health policies. Here, we aim to develop standard protocols for propagation, titration, and purification of Asian and Brazilian ZIKV strains, by systematically testing different cell types, kinetics, multiplicity of infection and centrifugation protocols...

Transient gene expression in mammalian cells is an efficient process to produce recombinant proteins for various research applications and large molecule therapeutics development. For the first time, we report a screen to identify human microRNAs (miRNAs) that increase titers after polyethylenimine (PEI) mediated transient transfection of a HEK293 cell line. From a library of 875 miRNAs, we identified 2 miRNAs, miR-26a-5p and miR-337-5p, that increased human IgG1 (huIgG1) yields by 50% and 25%, respectively...

REVIEW
Danielle S Bassett, Ankit N Khambhati
Network science and engineering provide a flexible and generalizable tool set to describe and manipulate complex systems characterized by heterogeneous interaction patterns among component parts. While classically applied to social systems, these tools have recently proven to be particularly useful in the study of the brain. In this review, we describe the nascent use of these tools to understand human cognition, and we discuss their utility in informing the meaningful and predictable perturbation of cognition in combination with the emerging capabilities of neurofeedback...

The relationship between biodiversity and the stability of ecosystem function is a fundamental question in community ecology, and hundreds of experiments have shown a positive relationship between species richness and the stability of ecosystem function. However, these experiments have rarely accounted for common ecological patterns, most notably skewed species abundance distributions and non-random extinction risks, making it difficult to know whether experimental results can be scaled up to larger, less manipulated systems...

Alexandra Lelia Dima, Dan Dediu
Adherence to medications is an important indicator of the quality of medication management and impacts on health outcomes and cost-effectiveness of healthcare delivery. Electronic healthcare data (EHD) are increasingly used to estimate adherence in research and clinical practice, yet standardization and transparency of data processing are still a concern. Comprehensive and flexible open-source algorithms can facilitate the development of high-quality, consistent, and reproducible evidence in this field. Some EHD-based clinical decision support systems (CDSS) include visualization of medication histories, but this is rarely integrated in adherence analyses and not easily accessible for data exploration or implementation in new clinical settings...

Ocular vasculature consists of the central retinal and ciliary vascular systems, which are essential to maintaining visual function. Many researchers have attempted to determine their origins and development; however, the detailed, stepwise process of ocular vasculature formation has not been established. In zebrafish, two angioblast clusters, the rostral and midbrain organizing centers, form almost all of the cranial vasculature, including the ocular vasculature, and these are from where the cerebral arterial and venous angioblast clusters, respectively, differentiate...

Protease-activated receptors (PARs) are a family of G-protein-coupled receptors (GPCRs) that are irreversibly activated by proteolytic cleavage of the N terminus, which unmasks a tethered peptide ligand that binds and activates the transmembrane receptor domain, eliciting a cellular cascade in response to inflammatory signals and other stimuli. PARs are implicated in a wide range of diseases, such as cancer and inflammation. PARs have been the subject of major pharmaceutical research efforts but the discovery of small-molecule antagonists that effectively bind them has proved challenging...

REVIEW
Yohei Shirakami, Masaya Ohnishi, Hiroyasu Sakai, Takuji Tanaka, Masahito Shimizu
Colorectal cancer is a major healthcare concern worldwide. Many experimental and clinical studies have been conducted to date to discover agents that help in the prevention of this disease. Chronic inflammation in colonic mucosa and obesity, and its related metabolic abnormalities, are considered to increase the risk of colorectal cancer. Therefore, treatments targeting these factors might be a promising strategy to prevent the development of colorectal cancer. Among a number of functional foods, various phytochemicals, including tea catechins, which have anti-inflammatory and anti-obesity properties, and medicinal agents that ameliorate metabolic disorders, might also be beneficial in the prevention of colorectal cancer...

PURPOSE OF REVIEW: Sarcoma is a basket term for mesenchymal tumors for which more than 75 genetically and histologically distinct subtypes are recognized. Therapeutic progress has largely been achieved with classical chemotherapeutic drugs that were tested in empirical clinical trials. However, outcome in metastatic patients remains poor and with few exceptions numerous trials have failed or only provided limited improvement in recent years. RECENT FINDINGS: Given the genomic heterogeneity, preclinical model systems will be indispensable to identify new molecular targets and to prioritize drugs and drug combinations...

The growing number of Spanish speakers in the United States poses communication challenges for healthcare providers. Language barriers in pediatric acute care have been associated with an increased risk for adverse events, longer hospital stays, and decreased quality of care. In addition, clinicians' usage of interpreter services is inconsistent. In fact, nurses often lack interpreter support during daily bedside care. Nursing staff at a pediatric children's hospital in the southeastern United States identified bedside communication with Spanish-speaking patients and families as a clinical challenge...
