the brain at different stages of the disease with hyper- and hypoconnectivity cycles that can occur repeatedly. Nevertheless, further studies investigating both amyloid and τ deposition simultaneously while considering the stage of Alzheimer dementia are required to assess the accuracy of this hypothesis. Given the aging population and the high prevalence of cognitive impairment in older hospitalized patients, it is essential to provide good fundamental care to these vulnerable patients, who easily might be affected by poor outcomes as delirium. Risk factors for delirium are, for example, cognitive impairment, old age, pain, and sleep deprivation. Different symptoms are often unidentified in hospitals, and associated with poor well-being, but this is rarely studied in older patients with cognitive impairment. The study aim was to examine symptoms and sense of well-being in older hospitalized patients with cognitive impairment, as self-reported and reported in patient records. Exploratory quantitative subgroup ( = 25) analysis of a point-prevalence study ( = 210). Inclusion criteria were age ≥65, and cognitive impairment. Data were collected through structured interviews, validated instruments, and patient records. Associations between well-being and symptoms, and concordance between the occurrence of sviation differs between patients with and without cognitive impairment, and if a total symptom burden increases the risk of poor outcomes as delirium in vulnerable patients.To our knowledge, this hypothesis-generating study is one of few studies that describe both symptoms and well-being as self-reported and reported in patient records, in vulnerable patients due to old age, cognitive impairment, and hospitalization. Despite the limited sample size, the results indicate that symptoms were more insufficient alleviated in these patients compared to patients with normal cognitive function in other studies. To our knowledge, this has not been shown previously. Additionally, patients' own experiences were sparsely reported in their records. A larger sample size and longitudinal design has the potential to determine if symptom alleviation differs between patients with and without cognitive impairment, and if a total symptom burden increases the risk of poor outcomes as delirium in vulnerable patients.[This corrects the article DOI 10.3389/fpls.2018.00947.].The mechanism of miRNA-mediated root growth and development in response to nutrient deficiency in peanut (Arachis hypogaea L.) is still unclear. In the present study, we found that both nitrogen (N) and potassium (K) deficiency resulted in a significant reduction in plant growth, as indicated by the significantly decreased dry weight of both shoot and root tissues under N or K deficiency. Both N and K deficiency significantly reduced the root length, root surface area, root volume, root vitality, and weakened root respiration, as indicated by the reduced O2 consuming rate. N deficiency significantly decreased primary root length and lateral root number, which might be associated with the upregulation of miR160, miR167, miR393, and miR396, and the downregulation of AFB3 and GRF. The primary and lateral root responses to K deficiency were opposite to that of the N deficiency condition. The upregulated miR156, miR390, NAC4, ARF2, and AFB3, and the downregulated miR160, miR164, miR393, and SPL10 may have contributed to the growth of primary roots and lateral roots under K deficiency. Overall, roots responded differently to the N or K deficiency stresses in peanuts, potentially due to the miRNA-mediated pathway and mechanism.Pine wilt disease (PWD), caused by the plant-parasitic nematode Bursaphelenchus xylophilus, has become a severe environmental problem in the Iberian Peninsula with devastating effects in Pinus pinaster forests. Despite the high levels of this species' susceptibility, previous studies reported heritable resistance in P. pinaster trees. Understanding the basis of this resistance can be of extreme relevance for future programs aiming at reducing the disease impact on P. pinaster forests. In this study, we highlighted the mechanisms possibly involved in P. pinaster resistance to PWD, by comparing the transcriptional changes between resistant and susceptible plants after infection. Our analysis revealed a higher number of differentially expressed genes (DEGs) in resistant plants (1,916) when compared with susceptible plants (1,226). TGF-beta signaling Resistance to PWN is mediated by the induction of the jasmonic acid (JA) defense pathway, secondary metabolism pathways, lignin synthesis, oxidative stress response genes, and resistance genes. Quantification of the acetyl bromide-soluble lignin confirmed a significant increase of cell wall lignification of stem tissues around the inoculation zone in resistant plants. In addition to less lignified cell walls, susceptibility to the pine wood nematode seems associated with the activation of the salicylic acid (SA) defense pathway at 72 hpi, as revealed by the higher SA levels in the tissues of susceptible plants. Cell wall reinforcement and hormone signaling mechanisms seem therefore essential for a resistance response.The emergence of genome-editing technology has allowed manipulation of DNA sequences in genomes to precisely remove or replace specific sequences in organisms resulting in targeted mutations. In plants, genome editing is an attractive method to alter gene functions to generate improved crop varieties. Genome editing is thought to be simple to use and has a lower risk of off-target effects compared to classical mutation breeding. Furthermore, genome-editing technology tools can also be applied directly to crops that contain complex genomes and/or are not easily bred using traditional methods. Currently, highly versatile genome-editing tools for precise and predictable editing of almost any locus in the plant genome make it possible to extend the range of application, including functional genomics research and molecular crop breeding. Vegetables are essential nutrient sources for humans and provide vitamins, minerals, and fiber to diets, thereby contributing to human health. In this review, we provide an overview of the brief history of genome-editing technologies and the components of genome-editing tool boxes, and illustrate basic modes of operation in representative systems.
