vulgaris with Sphingopyxis sp. and Pseudomonas sp. Out-competition of C. vulgaris due to ammonium or phosphate limitation was not observed, despite significantly elevated growth of Sphingopyxis sp. and Tistrella sp. (p less then 0.05). Nevertheless, C. vulgaris growth was impaired by Tistrella sp. Hence, the study provides a selection of stable indigenous prokaryotes and eukaryotes for artificially tailoring microbial biocenoses. Following a bottom-up approach, it provides a base for controlled co-cultures and thus the establishment of even more complex biocenoses using inter-kingdom assemblages. Such assemblages can benefit from functional richness for improved nutrient utilization, as well as bacterial load control, which can enhance microalgal feedstock production through improved culture stability and productivity.Although the clinical outcomes of cystic fibrosis (CF) have been markedly improved through the recent implementation of novel CF transmembrane conductance regulator (CFTR) modulator drugs, robust and reliable biomarkers are still demanded for the early detection of CF lung disease progression, monitoring treatment efficacy and predicting life-threatening clinical complications. Thus, there is an unmet need to identify and validate novel, ideally blood based biomarkers with strong correlations to the severity of CF lung disease, which represents a major contribution to overall CF morbidity and mortality. In this review, we aim to summarize the utility of thus far studied blood-, sputum- and bronchoalveolar lavage (BAL)-based biomarkers to evaluate inflammatory conditions in the lung and to follow treatment efficacy in CF. Measurements of sweat chloride concentrations and the spirometric parameter FEV1 are currently utilized to monitor CFTR function and the effect of various CF therapies. Nonetheless, both have inherent pitfalls and limitations, thus routinely analyzed biomarkers in blood, sputum or BAL samples are required as surrogates for lung disorders. Recent discovery of new protein (e.g. HE4) and RNA-based biomarkers (e.g. microRNAs) may offer a higher efficacy, which in aggregate may be valuable to evaluate disease prognosis and to substantiate CF drug efficacy.The vast majority of eukaryotic life is made up of single cells commonly referred to as protists. In this primer, Leander provides an introduction to predatory protists - cells that eat other cells. This lifestyle, in particular the use of phagocytosis, makes endosymbiosis possible and enabled the evolution of complex cells.Studying the evolution of metabolism is technically challenging. A new study combining in silico metabolic maps and phylogenomics allows reconstructing the diversification of plant metabolism across one billion years of evolution.Clinical practice guidelines are the most important documents for the incorporation of scientific evidence in health decision making through the formulation of recommendations. There is a variable terminology used to refer to the documents that guide health professionals in decision making. When clinical practice guidelines are of high quality, they appraise contextual aspects such as the use of resources, applicability, and patients values and preferences. Even so, they are not recipe books, since they may have limitations. In this review, we propose to clarify the different denominations across the various types of documents available to guide the health professional when making clinical decisions. We discuss the main characteristics of clinical practice guidelines, quality assessment, challenges, and limitations.Aims To systemically review the efficacy and safety of auricular point therapy in patients with cancer-related fatigue. Design A systematic review and meta-analysis of randomized controlled trials. Data sources Eight electronic databases (PubMed, CENTRAL, Embase, CINAHL, Web of Science, China Biology Medicine, China National Knowledge Infrastructure and WanFang Data Knowledge Service Platform) were explored for randomized controlled trials from their inception to 1 December 2018. Review methods The risk of bias assessment tool was adopted in accordance with Cochrane Handbook 5.3.0. All included studies reported the effects on cancer-related fatigue as the primary outcome. Tyrphostin B42 concentration Effect size was estimated using relative risk, standardized mean difference or mean difference with a corresponding 95% confidence interval. Review Manager 5.3 was used for meta-analysis. Results Six studies comprising 394 patients were included. The results of meta-analysis showed that auricular point therapy plus standard care produced more positive effects on cancer-related fatigue and quality of life than standard care alone. It could significantly improve the role, emotional, cognitive, and social functions of patients with cancer-related fatigue. Conclusions Auricular point therapy may be a safe therapy to relieve cancer-related fatigue and enhance the quality of life of patients with cancer. However, the evidence was inconclusive due to limitations on the quantity and quality of included studies. Rigorously designed randomized controlled trials should be conducted to verify the results. Impact Auricular point therapy is a simple and safe therapeutic approach that may alleviate cancer-related fatigue of common complications in patients with cancer and it is worth promoting in the community, family, and hospital. Moreover, the research findings can provide suggestions and inspiration for nurses and researchers to implement the proposal, which is conducive to design more rigorous and high-quality randomized controlled trials.The formation of acetylcholine receptor (AChR) clusters at the postsynaptic muscle membrane in response to motor innervation is a key event in the development of the neuromuscular junction. The synaptic AChR clustering process is initiated by motor axon-released agrin, which activates a tyrosine kinase-based signaling pathway to cause AChR aggregation. In cultured muscle cells, AChR clustering is elicited by diverse nonneural signals, and this process is also mediated by tyrosine kinases. Conversely, the formation of new AChR clusters induced by innervation or nonneural stimuli is unfailingly associated with the dispersal of pre-existing AChR clusters, and this process is mediated by tyrosine phosphatases. In this review, we address how local kinase activation leads to global phosphatase action in muscle. More specifically, we discuss the roles of Src kinase and the SH2 domain-containing tyrosine phosphatase Shp-2 in establishing a regenerative mechanism to propagate the AChR cluster dispersing signal extrasynaptically and in defining the boundary of cluster formation subsynaptically.Yaguchi et al. establish a homozygous knock-out sea urchin line by applying the CRISPR-Cas9 system to a new model species, Temnopleurus reevesii, whose breeding cycle takes about half a year.Head and neck cancer (HNC), which includes epithelial malignancies of the upper aerodigestive tract (oral cavity, oropharynx, pharynx, hypopharynx, larynx, and thyroid), are slowly but consistently increasing, while the overall survival rate remains unsatisfactory. Because of the multifunctional anatomical intricacies of the head and neck, disease progression and therapy-related side effects often severely affect the patient's appearance and self-image, as well as their ability to breathe, speak, and swallow. Patients with HNC require a multidisciplinary approach involving surgery, radiation therapy, and chemotherapeutics. Chemotherapy is an important part of the comprehensive treatment of tumors, especially advanced HNC, but drug resistance is the main cause of poor clinical efficacy. The most important determinant of this phenomenon is still largely unknown. Recent studies have shown that non-coding RNAs have a crucial role in HNC drug resistance. In addition, they can serve as biomarkers in the diagnosis, treatment, and prognosis of HNCs. In this review, we summarize the relationship between non-coding RNAs and drug resistance of HNC, and discuss their potential clinical application in overcoming HNC chemoresistance.Preterm infants are a population at high risk for mortality and adverse health outcomes. With recent improvements in survival to childhood, increasing attention is being paid to risk of long-term morbidity, specifically during childhood and young-adulthood. Although numerous tools for predicting the functional outcomes of preterm neonates have been developed in the past three decades, no studies have provided a comprehensive overview of these tools, along with their strengths and weaknesses. The purpose of this article is to provide an in-depth, narrative review of the current risk models available for predicting the functional outcomes of preterm neonates. A total of 32 studies describing 43 separate models were considered. We found that most studies used similar physiologic variables and standard regression techniques to develop models that primarily predict the risk of poor neurodevelopmental outcomes. With a recently expanded knowledge regarding the many factors that affect neurodevelopment and other impong their functional outcomes.Introduction Splenic trauma is quite rare after colonoscopy and can be overlooked as a complication when a patient presents with severe abdominal pain. It can be difficult to diagnose without appropriate imaging, but it should be considered as part of the differential in a patient arriving for evaluation of left upper quadrant abdominal pain. Presentation of case In this case series, we discuss four patients who presented to our institution with splenic trauma specifically after colonoscopy. These patients were diagnosed with splenic trauma utilizing computed tomography (CT) scans of the abdomen and pelvis. They were all immediately transferred to our surgical intensive care unit (SICU) for close monitoring and serial hemoglobin checks. Two of the four patients had decreasing hemoglobin levels and were monitored until they underwent interventional radiology (IR) angiography and angioembolization. The other two patients had significant transfusion requirements and ultimately went to the operating room for an open splenectomy. All four of these patients did well after their interventions, although one of them required longer hospitalization while on the ventilator secondary to Haemophilus infection. Discussion This case series recognizes that there is potential for quite severe splenic trauma after colonoscopy. While one of the four patients did have a history of prior splenic trauma, the other three had no history of trauma. Conclusion These cases demonstrate that this complication should be managed similarly to traumatic splenic injury unrelated to colonoscopy, and that non-operative treatment remain a possibility. Certainly, non-operative management requires a SICU and IR capabilities to be successful. If the patient becomes unstable, they should undergo the appropriate operative intervention.Flamholz and Shih explain how photosynthetic organisms on earth have evolved carbon dioxide concentrating mechanisms to contend with an increased abundance of oxygen in the atmosphere. This critical innovation has occurred numerous times and comes in two basic flavors.
