Identifying the specific role of physical guidance cues in the growth of neurons is crucial for understanding the fundamental biology of brain development and for designing scaffolds for tissue engineering. Here, we investigate the structural significance of nanoscale topographies as physical cues for neurite outgrowth and circuit formation by growing neurons on semiconductor nanowires. We monitored neurite growth using optical and scanning electron microscopy, and evaluated the spontaneous neuronal network activity using functional calcium imaging...

Theoretical studies are essential for the structural characterization of clusters, when it comes to rationalize their unique size-dependent properties and composition. However, the rapid growth of local minima on the potential energy surface (PES), with respect to cluster size, makes the candidate identification a challenging undertaking. In this article, we introduce a hybrid strategy to explore the PES of clusters. This proposal involves the use of a biased initial population of a genetic algorithm procedure...

BACKGROUND AND OVERVIEW: "Pink esthetics," which are considered to be as important as "white esthetics," have attracted increasing attention. To date, clinicians rarely have applied computer-aided design and computer-aided manufacturing (CAD/CAM) techniques in the rebuilding of the contour of the marginal gingiva in the esthetic zone. CASE DESCRIPTION: In this case report, the authors describe a female patient who had gingival inflammation and an asymmetrical contour of the marginal gingiva of the anterior maxillary teeth because previously placed ceramic crowns violated the biological width...

OBJECTIVES: The Endangered collared brown lemur (Eulemur collaris) is the largest primate living in the littoral forest of southeastern Madagascar, a top priority habitat for biodiversity conservation on the island. Because this lemur is a key seed-disperser, an evaluation of the structure and connectivity of the populations surviving in the forest fragments is urgently needed to guide conservation plans. MATERIALS AND METHODS: Genetic variability at autosomal microsatellites and mitochondrial DNA was investigated in a total of 49 collared brown lemurs sampled by non-invasive methods in three littoral forest fragments and in the nearby lowland humid forest...

The immune system of the gastrointestinal (GI) tract manages the significant task of recognizing and eliminating pathogens while maintaining tolerance of commensal bacteria. Dysregulation of this delicate balance can be detrimental, resulting in severe inflammation, intestinal injury, and cancer. Therefore, mechanisms to relay important signals regulating cell growth and immune reactivity must be in place to support GI homeostasis. Type I interferons (IFN-I) are a family of pleiotropic cytokines, which exert a wide range of biological effects including promotion of both pro- and anti-inflammatory activities...

African trypanosomiasis is still a threat to human health due to the severe side-effects of current drugs. We identified selective tubulin inhibitors that showed the promise to the treatment of this disease, which was based on the tubulin protein structural difference between mammalian and trypanosome cells. Further lead optimization was performed in the current study to improve the efficiency of the drug candidates. We used Trypanosoma brucei brucei cells as the parasite model, and human normal kidney cells and mouse macrophage cells as the host model to evaluate the compounds...

Targeted therapies guided by molecular diagnostics have become a standard treatment of lung cancer. Epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) rearrangements are currently used as the best predictive biomarkers for EGFR tyrosine kinase inhibitors and ALK inhibitors, respectively. Besides EGFR and ALK, the list of druggable genetic alterations has been growing, including ROS1 rearrangements, RET rearrangements, and MET alterations. In this situation, pathologists should carefully manage clinical samples for molecular testing and should do their best to quickly and accurately identify patients who will benefit from precision therapeutics...

This review aims to present an innovative concept of high value added lipids produced by heterotrophic microorganisms, bacteria and fungi, using carbon sources, such as sugars, acids and alcohols that could come from sugarcane vinasse, which is the main byproduct from ethanol production that is released in the distillation step. Vinasse is a rich carbon source and low-cost feedstock produced in large amounts from ethanol production. In 2019, the Brazilian Ministry of Agriculture, Livestock and Food Supply estimates that growth of ethanol domestic consumption will be 58...

Deregulation of MYC family proteins in cancer is associated with a global reprogramming of gene expression, ultimately promoting glycolytic pathways, cell growth, and proliferation. It is well known that MYC upregulation triggers cell-autonomous apoptosis in normal tissues, while frankly malignant cells develop resistance to apoptotic stimuli, partly resulting from MYC addiction. As well as inducing cell-autonomous apoptosis, MYC upregulation is able to trigger non cell-autonomous apoptotic death through an evolutionarily conserved mechanism known as "cell competition"...

The growth of online education has created a learning environment that permits nontraditional students the opportunity for degree completion without the burden of relocation. Given the shortage of nurses at all educational levels, many institutions of higher learning have created online programs to meet the needs of both the student and the profession as a whole. Although convenient for the student and beneficial for the nursing profession, the online learning environment can present numerous challenges. Among these challenges are acts of student incivility-creating a difficult work environment for faculty and, at times, negatively affecting other students...

Wildlife managers routinely seek to establish sustainable limits of sport harvest or other regulated forms of take while confronted with considerable uncertainty. A growing body of ecological research focuses on methods to describe and account for uncertainty in management decision-making and to prioritize research and monitoring investments to reduce the most influential uncertainties. We used simulation methods incorporating measures of demographic uncertainty to evaluate risk of overharvest and prioritize information needs for North American sea ducks (Tribe Mergini)...

The field of cancer genomics is rapidly evolving and has led to the development of new therapies. Knowledge of commonly involved cellular pathways and genetic mutations is now essential for radiologists reading oncology cases. Radiogenomics is an emerging area of research that seeks to correlate imaging features with cancer genotypes. Such knowledge may extend the utility of multiparametric imaging to yield information regarding cancer prognosis and likelihood of therapeutic response. To date, only a handful of radiogenomics studies have been performed to evaluate solid tumors of the body, and there is much to explore...

CHO cell is an important host for biopharmaceutical production. Generation of stable CHO cell typically requires co-integration of dhfr and foreign gene into chromosomes and subsequent methotrexate (MTX) selection for co-amplification of dhfr and foreign gene. CRISPR interference (CRISPRi) is an emerging system that effectively suppresses gene transcription through the coordination of dCas9 protein and guide RNA (gRNA). However, CRISPRi has yet to be exploited in CHO cells. Here we constructed vectors expressing the functional CRISPRi system and proved effective CRISPRi-mediated suppression of dhfr transcription in CHO cells...

Forest degradation is a global phenomenon and while being an important indicator and precursor to further forest loss, carbon emissions due to degradation should also be accounted for in national reporting within the frame of UN REDD+. At regional to country scales, methods have been progressively developed to detect and map forest degradation, with these based on multi-resolution optical, synthetic aperture radar (SAR) and/or LiDAR data. However, there is no one single method that can be applied to monitor forest degradation, largely due to the specific nature of the degradation type or process and the timeframe over which it is observed...

Streptococcus agalactiae (group B Streptococcus; GBS) is a leading cause of invasive bacterial infections in newborns, typically acquired vertically during childbirth secondary to maternal vaginal colonization. Human milk oligosaccharides (HMOs) have important nutritional and biological activities that guide development of the infant's immune system and shape the composition of normal gut microbiota. In this manner, HMOs help protect against pathogen colonization and reduce risk of infection. In the course of our studies of HMO-microbial interactions, we unexpectedly uncovered a novel HMO property to directly inhibit the growth of GBS, independent of host immunity...

BACKGROUND: Accompanying the unprecedented growth in the older adult population worldwide is an increase in the prevalence of frailty, an age-related clinical state of increased vulnerability to stressor events. This increased vulnerability results in lower social engagement and quality of life, increased dependency, and higher rates of morbidity, health service utilization and mortality. Early identification of frailty is necessary to guide implementation of interventions to prevent associated functional decline...
