REVIEW
John Withers, Xinnian Dong
Plants have evolved multi-layered molecular defense strategies to protect against pathogens. Plant immune signaling largely relies on post-translational modifications (PTMs) to induce rapid alterations of signaling pathways to achieve a response that is appropriate to the type of pathogen and infection pressure. In host cells, dynamic PTMs have emerged as powerful regulatory mechanisms that cells use to adjust their immune response. PTM is also a virulence strategy used by pathogens to subvert host immunity through the activities of effector proteins secreted into the host cell...

The Physician Payments Sunshine Act (PPSA) requires health care product manufacturers to report to the federal government payments more than $10 to physicians. Bringing unprecedented transparency to medicine, PPSA holds great potential for enabling medical stakeholders to manage conflicts of interest (COI) and build patient trust-crucial responsibilities of medical professionalism. The authors conducted six focus groups with 42 physicians in Chicago, IL, San Francisco, CA, and Washington, DC, to explore attitudes and experiences around PPSA...

P M Comiskey, A L Yarin, D Attinger
High-speed videos of blood spatter due to a gunshot taken by the Ames Laboratory Midwest Forensics Resource Center (MFRC) [1] are analyzed. The videos used in this analysis were focused on a variety of targets hit by a bullet which caused either forward, backward, or both types of blood spatter. The analysis process utilized particle image velocimetry (PIV) and particle analysis software to measure drop velocities as well as the distributions of the number of droplets and their respective side view area. The results of this analysis revealed that the maximal velocity in the forward spatter can be about 47±5m/s and for the backward spatter - about 24±8m/s...

In 1968, the American Medical Association resolved to accept qualified graduates of osteopathic medical schools into its accredited Graduate Medical Education (GME) programs. An equally momentous decision was arrived at in 2014 when the Accreditation Council for Graduate Medical Education (ACGME), the American Osteopathic Association (AOA), and the American Association of Colleges of Osteopathic Medicine (AACOM) resolved to institute a single unified GME accreditation system by July 1, 2020. As envisioned, the unified accreditation system will all but assure system-wide consistency of purpose and practice in anticipation of the Next Accreditation System (NAS) of the ACGME...

Herein, we focus on preparing a highly efficient photocatalytic material to construct a signal-on photoelectrochemical (PEC) sensing platform in view of the rigorous demand of accurate miRNA quantification. The well-dispersed Pt nanoclusters-coated copper phosphate ultrathin nanosheets (PtNCs/Cu3(PO4)2NSs) were first successfully synthesized as a photoelectrode material. Because of the ultrathin two-dimensional lamellar structure of Cu3(PO4)2NSs with a 1.3 nm thickness, as well as the homogeneous size and abundant PtNCs loaded on Cu3(PO4)2NSs, the resultant PtNCs/Cu3(PO4)2NSs were employed as a photoelectrode material for the first time and revealed outstanding photocatalytic activity in PEC sensing as a substrate...

Infections are one of the main causes of morbidity and mortality in the population. The choice of empirical treatment is one of the most common decisions facing the physician. This first decision has consequences in the prognosis of the patient and the costs associated with the process. This review attempts to summarize the aspects that can lead to failure of antibiotic treatment by considering microbiological and pharmacological aspects, patient profile and infectious focus control. In addition, a series of recommendations are established to minimize this risk, from the point of view of diagnostic accuracy, adequate severity stratification of the patient, knowledge of the pharmacokinetic and pharmacodynamic aspects of antibiotics and control of the infectious focus...

BACKGROUND: Network analysis has become a relevant approach to analyze cascading species extinctions resulting from perturbations on mutualistic interactions as a result of environmental change. In this context, it is essential to be able to point out key species, whose stability would prevent cascading extinctions, and the consequent loss of ecosystem function. In this study, we aim to explain how the k-core decomposition sheds light on the understanding the robustness of bipartite mutualistic networks...

BACKGROUND: Rising dementia prevalence rates rise combined with the policy objective of enabling people with dementia to remain living at home, means that there will be a growing demand for dementia care in the community setting. However, GPs are challenged by dementia care and have identified it as an area in which further training is needed. Previous studies of GPs dementia care educational needs have explored the views of GPs alone, without taking the perspectives of people with dementia and family carers into account...

Creating realistic three-dimensional (3D) experiences has been a very active area of research and development, and this article describes progress and what remains to be solved. A very active area of technical development has been to build displays that create the correct relationship between viewing parameters and triangulation depth cues: stereo, motion, and focus. Several disciplines are involved in the design, construction, evaluation, and use of 3D displays, but an understanding of human vision is crucial to this enterprise because in the end, the goal is to provide the desired perceptual experience for the viewer...

Our perceptual abilities significantly improve with practice. This phenomenon, known as perceptual learning, offers an ideal window for understanding use-dependent changes in the adult brain. Different experimental approaches have revealed a diversity of behavioral and cortical changes associated with perceptual learning, and different interpretations have been given with respect to the cortical loci and neural processes responsible for the learning. Accumulated evidence has begun to put together a coherent picture of the neural substrates underlying perceptual learning...

Mitochondria are the main consumers of molecular O2 in a cell as well as an abundant source of reactive oxygen species (ROS). Both, molecular oxygen and ROS are powerful regulators of the hypoxia-inducible factor-1α-subunit (HIF-α). While a number of mechanisms in the oxygen-dependent HIF-α regulation are quite well known, the view with respect to mitochondria is less clear. Several approaches using pharmacological or genetic tools targeting the mitochondrial electron transport chain (ETC) indicated that ROS, mainly formed at the Rieske cluster of complex III of the ETC, are drivers of HIF-1α activation...

BACKGROUND: Type 2 diabetes is impacting millions of people globally; however, many future cases can be prevented through lifestyle changes and interventions. Primary care is an important setting for diabetes prevention, for at-risk populations, because it is a patient's primary point of contact with the health care system and professionals can provide lifestyle counselling and support, as well as monitoring health outcomes. These are all essential elements for diabetes prevention for at-risk adults...

A commonly expressed view is that short-term memory (STM) is nothing more than activated long-term memory. If true, this would overturn a central tenet of cognitive psychology-the idea that there are functionally and neurobiologically distinct short- and long-term stores. Here I present an updated case for a separation between short- and long-term stores, focusing on the computational demands placed on any STM system. STM must support memory for previously unencountered information, the storage of multiple tokens of the same type, and variable binding...

This article examines the 1940s debates regarding the status and professional orthodoxy of psychoanalysis following Sigmund Freud's death, by exploring the Anna Freud-Melanie Klein Controversial Discussions in the British Psychoanalytical Society. Focusing on the work of now-forgotten analysts Melitta Schmideberg and Edward Glover, and on their relationship with Klein and her supporters, the article reveals how these neglected, yet important, debates were complicated by interpersonal and professional ties, processes of the professionalization, and changing gender norms...

The primary aim of this study was to test the hypothesis that a patient's subjective assessments of the dentist's technical competence, quality of care, and anticipated restoration longevity during a restorative visit are predictive of restoration outcome. This prospective cohort study involved 3,326 patients who received treatment for a defective restoration in a permanent tooth, participated in a baseline patient satisfaction survey, and returned for follow-up. Of the 4,400 restorations that were examined by 150 dentists, 266 (6%) received additional treatment after baseline...

Neuroscientists are increasingly collecting multimodal data during experiments and observational studies. Different data modalities-such as EEG, fMRI, LFP, and spike trains-offer different views of the complex systems contributing to neural phenomena. Here, we focus on joint modeling of LFP and spike train data, and present a novel Bayesian method for neural decoding to infer behavioral and experimental conditions. This model performs supervised dual-dimensionality reduction: it learns low-dimensional representations of two different sources of information that not only explain variation in the input data itself, but also predict extra-neuronal outcomes...

BACKGROUND: Accessibility of water immersion for labour and/or birth is often dependent on the care provider and also the policies/guidelines that underpin practice. With little high quality research about the safety and practicality of water immersion, particularly for birth, policies/guidelines informing the practice may lack the evidence necessary to ensure practitioner confidence surrounding the option thereby limiting accessibility and women's autonomy. AIM: The aims of the study were to determine how water immersion policies and/or guidelines are informed, who interprets the evidence to inform policies/guidelines and to what extent the policy/guideline facilitates the option for labour and birth...

Correlative light and electron microscopy (CLEM) is a powerful tool to perform ultrastructural analysis of targeted tissues or cells. The large field of view of the light microscope (LM) enables quick and efficient surveys of the whole specimen. It is also compatible with live imaging, giving access to functional assays. CLEM protocols take advantage of the features to efficiently retrace the position of targeted sites when switching from one modality to the other. They more often rely on anatomical cues that are visible both by light and electron microscopy...
