A comparative machine learning study of schizophrenia biomarkers derived from functional connectivity.

Functional connectivity holds promise as a biomarker of schizophrenia. Yet, the high dimensionality of predictive models trained on functional connectomes, combined with small sample sizes in clinical research, increases the risk of overfitting. Recently, low-dimensional representations of the connectome such as macroscale cortical gradients and gradient dispersion have been proposed, with studies noting consistent gradient and dispersion differences in psychiatric conditions.

A function-based mapping of sensory integration along the cortical hierarchy.

Sensory information mainly travels along a hierarchy spanning unimodal to transmodal regions, forming multisensory integrative representations crucial for higher-order cognitive functions. Here, we develop an fMRI based two-dimensional framework to characterize sensory integration based on the anchoring role of the primary cortex in the organization of sensory processing. Sensory magnitude captures the percentage of variance explained by three primary sensory signals and decreases as the hierarchy ascends, exhibiting strong similarity to the known hierarchy and high stability across different conditions.

Utilising a non-surgical intervention in the knee osteoarthritis care pathway: a 6-year retrospective audit on NHS patients.

Background: Knee osteoarthritis (OA) is a chronic, debilitating, musculoskeletal condition that affects millions. The increase in prevalence and its economic impact on healthcare and society raise the need for additional non-surgical interventions.

Objective: To assess the referral rates to secondary care consultation and clinical outcomes in patients with severe knee OA treated with a home-based, non-surgical intervention.

Impact of the Integrative Oncology Scholars Program on Oncology Providers' Key Knowledge of Dietary Supplements and Antioxidants for Providing Evidence-based Oncology Care.

Dietary supplements are commonly used among cancer survivors. Oncology providers rarely receive training about dietary supplements. We evaluated whether e-learning modules could improve oncology providers' dietary supplement knowledge.

Examining the barriers to accepting big health data from a health marketeer's perspective.

Studies have shown that the sharing of big health data can improve patient management across primary and secondary care sectors. It can also reduce costs and can enhance the medical research process. Unfortunately, many big health data initiatives are being impeded because of a range of complex issues.

Cortical Morphology and White Matter Tractography of Three Phylogenetically Distant Primates: Evidence for a Simian Elaboration.

Comparative neuroimaging has been used to identify changes in white matter architecture across primate species phylogenetically close to humans, but few have compared the phylogenetically distant species. Here, we acquired postmortem diffusion imaging data from ring-tailed lemurs (Lemur catta), black-capped squirrel monkeys (Saimiri boliviensis), and rhesus macaques (Macaca mulatta). We were able to establish templates and surfaces allowing us to investigate sulcal, cortical, and white matter anatomy.

Integrative Oncology Education: An Emerging Competency for Oncology Providers.

A growing number of cancer patients use complementary and alternative therapies during and after conventional cancer treatment. Patients are often reluctant to discuss these therapies with their oncologist, and oncologists may have limited knowledge and confidence on how to advise patients on the appropriate use. Integrative oncology is a patient-centered, evidence-informed field that utilizes mind-body practices, lifestyle modifications and/or natural products interwoven with conventional cancer treatment.

A collaborative resource platform for non-human primate neuroimaging.

Neuroimaging non-human primates (NHPs) is a growing, yet highly specialized field of neuroscience. Resources that were primarily developed for human neuroimaging often need to be significantly adapted for use with NHPs or other animals, which has led to an abundance of custom, in-house solutions. In recent years, the global NHP neuroimaging community has made significant efforts to transform the field towards more open and collaborative practices.

Integrative Oncology Scholars Program: A Model for Integrative Oncology Education.

Objectives: Oncology providers are often confronted by patients who use complementary or alternative therapies, but have limited knowledge or confidence on how to advise patients on appropriate use. Despite this, there are few opportunities for oncology providers to learn about complementary or alternative therapies, while at the same time there is a high demand for integrative oncology (IO) training. To address a gap in IO educational opportunities, and particularly for nonphysicians, we created the Integrative Oncology Scholars (IOS) Program.

Phospho-site mutants of the RNA Polymerase II C-terminal domain alter subtelomeric gene expression and chromatin modification state in fission yeast.

Eukaryotic gene expression requires that RNA Polymerase II (RNAP II) gain access to DNA in the context of chromatin. The C-terminal domain (CTD) of RNAP II recruits chromatin modifying enzymes to promoters, allowing for transcription initiation or repression. Specific CTD phosphorylation marks facilitate recruitment of chromatin modifiers, transcriptional regulators, and RNA processing factors during the transcription cycle.

Public Health and Preventive Medicine Meet Integrative Health: Applications of Competency Mapping to Curriculum Education at the University of Michigan.

The University of Michigan School of Public Health Preventive Medicine Residency (UMSPH PMR) Integrative Medicine Program (IMP) was developed to incorporate integrative medicine (IM), public health, and preventive medicine principles into a comprehensive curriculum for preventive medicine residents and faculty. The objectives of this project were to (1) increase the preventive medicine workforce skill sets based in complementary and alternative medicine and IM that would address individual and population health issues; (2) address the increasing demand for evidence-based IM by training physicians to implement cost-effective primary and secondary prevention services and programs; and (3) share lessons learned, curriculum evaluations, and best practices with the larger cohort of funded IM PMR programs. The UMSPH PMR collaborated with University of Michigan IM faculty to incorporate existing IM competencies with those already established for preventive medicine and public health residency training as the first critical step for IMP curriculum integration.

Single gene insertion drives bioalcohol production by a thermophilic archaeon.

Bioethanol production is achieved by only two metabolic pathways and only at moderate temperatures. Herein a fundamentally different synthetic pathway for bioalcohol production at 70 °C was constructed by insertion of the gene for bacterial alcohol dehydrogenase (AdhA) into the archaeon Pyrococcus furiosus. The engineered strain converted glucose to ethanol via acetate and acetaldehyde, catalyzed by the host-encoded aldehyde ferredoxin oxidoreductase (AOR) and heterologously expressed AdhA, in an energy-conserving, redox-balanced pathway.

Resident wellness behaviors: relationship to stress, depression, and burnout.

Background And Objectives: Stress in medical education has been well documented, often with the primary focus on negative factors such as depression and burnout. Few studies have attempted to assess well-being mediating behaviors. This study describes the relationship between wellness behaviors and measures of well-being at the start of family medicine residency.

Integrative medicine in residency education: developing competency through online curriculum training.

Introduction: The Integrative Medicine in Residency (IMR) program, a 200-hour Internet-based, collaborative educational initiative was implemented in 8 family medicine residency programs and has shown a potential to serve as a national model for incorporating training in integrative/complementary/alternative medicine in graduate medical education.

Intervention: The curriculum content was designed based on a needs assessment and a set of competencies for graduate medical education developed following the Accreditation Council for Graduate Medical Education outcome project guidelines. The content was delivered through distributed online learning and included onsite activities.

Mindfulness training effects for parents and educators of children with special needs.

Parents and teachers of children with special needs face unique social-emotional challenges in carrying out their caregiving roles. Stress associated with these roles impacts parents' and special educators' health and well-being, as well as the quality of their parenting and teaching. No rigorous studies have assessed whether mindfulness training (MT) might be an effective strategy to reduce stress and cultivate well-being and positive caregiving in these adults.

Radiation damage in protein crystals is reduced with a micron-sized X-ray beam.

Radiation damage is a major limitation in crystallography of biological macromolecules, even for cryocooled samples, and is particularly acute in microdiffraction. For the X-ray energies most commonly used for protein crystallography at synchrotron sources, photoelectrons are the predominant source of radiation damage. If the beam size is small relative to the photoelectron path length, then the photoelectron may escape the beam footprint, resulting in less damage in the illuminated volume.

Role of luxS in Bacillus anthracis growth and virulence factor expression.

Quorum-sensing (QS), the regulation of bacterial gene expression in response to changes in cell density, involves pathways that synthesize signaling molecules (auto-inducers). The luxS/AI-2-mediated QS system has been identified in both gram-positive and gram-negative bacteria. Bacillus anthracis, the etiological agent of anthrax, possesses genes involved in luxS/AI-2-mediated QS, and deletion of luxS in B.
