Isolation of Possible Biocontrol Endophytic Bacteria from Solanum tuberosum Effective Against Streptomyces scabies.

Use of biological control offers a cost effective and environmentally safe method for controlling plant diseases. Biocontrol agents that can colonize roots and live endophytically within plant tissue should allow for effective disease control. The goal of this research was to develop protocols to isolate putative Streptomyces species from potato stem and tuber tissue due to their ability to produce inhibitory compounds which could potentially reduce diseases caused by Streptomyces scabies. Endophyte isolation from Solanum tuberosum (potato) plants (stem and tuber tissues) that were grown in a biocontrol field trial were the focus of this study. Several surface sterilization processes were assessed and two different tissue-processing methods were focused on to obtain endophytes: 1) excising cross-sections of stem tissue and 2) use of a maceration technique for tuber and stem tissue. From the stem tissue, four putative Streptomyces species were isolated; one of the four isolates was inhibitory to Streptomyces scabies in agar plate bioassays. To date, two putative Streptomyces species and several other bacterial species were isolated from tuber tissue. Further characterization of these isolates are underway with the goal of discovering endophytic pathogen-inhibiting bacteria that could then be used in concert with soil-dwelling biocontrol agents to enhance disease control of the potato scab pathogen

Why Has Personality Psychology Played an Outsized Role in the Credibility Revolution?

21 pages. Published at PsychOpen: 10.5964/ps.6001Personality is not the most popular subfield of psychology. But, in one way or another, personality psychologists have played an outsized role in the ongoing “credibility revolution” in psychology. Not only have individual personality psychologists taken on visible roles in the movement, but our field’s practices and norms have now become models for other fields to emulate (or, for those who share Baumeister’s (2016, https://doi.org/10.1016/j.jesp.2016.02.003) skeptical view of the consequences of increasing rigor, a model for what to avoid). In this article we discuss some unique features of our field that may have placed us in an ideal position to be leaders in this movement. We do so from a subjective perspective, describing our impressions and opinions about possible explanations for personality psychology’s disproportionate role in the credibility revolution. We also discuss some ways in which personality psychology remains less-than-optimal, and how we can address these flaws

*WINNER* Solar Energy for Bridgestone Nature Reserve at Chestnut Mountain

This project explores solar power generation systems as a potential renewable energy source for The Nature Conservancy's facility at Bridgestone Nature Reserve at Chestnut Mountain as a part of their goal to achieve carbon neutrality on the property. Initial research focused on the general function and composition of small-scale systems. Based on the energy usage listed on the energy audit provided by the Tennessee Valley Authority, the facility would require a 6-kWh photovoltaic (PV) system. A cost analysis revealed that the average cost of purchasing and installing this size system in Tennessee was $14,000. Energy storage options include sealed lead-acid batteries and lithium-ion batteries; however, cost analyses were not performed for storage options because The Nature Conservancy concluded that they do not plan to go off-grid. A reference sheet was constructed detailing this data and identifying potential installation companies for The Nature Conservancy to consult regarding quotes for the project. The next steps for the project will be obtaining quotes for the PV system, finalizing the decision of which company to hire, composing a case for support to raise funds for the project, and purchasing and installing the solar panel system

Infection associated acute interstitial nephritis; a case report

Background: Acute interstitial nephritis (AIN) is a clinico-pathological syndrome associated with a variety of infections, drugs, and sometimes with unknown causes. It is a common cause of acute kidney injury (AKI) and subsequent renal impairment, which often times is under-diagnosed. Infection-associated AIN occurs as a consequence of many systemic bacterial, viral, and parasitic infec-tions; however, its incidence has decreased significantly after the advent of antimicrobials. Infection-associated AIN presents with both oliguric or non-oliguric renal insufficiency, without the classical clinical triad of AIN (fever, rash, and arthralgia). In this scenario the renal function is usually reversible after the infection is treated. In most cases, patients with acute renal failure present with extra-renal manifestations typically detected in underlying infections. Renal biopsy serves as the most definitive test for both the diagnosis and prognosis of AIN. Case Presentation: In this paper, we will address one such case of biopsy-proven AIN. In this case, the patient presented with severe AKI induced by anaerobic streptococcus, leading to a periodontal abscess, which was successfully treated with corticosteroids and requiring renal replacement therapy (RRT). Conclusions: AIN should be considered in the differential for unexplained AKI. Initial management should include conservative therapy by withdrawing any suspected causative agent. Renal biopsy is needed for confirmation in cases where kidney function fails to improve within 5–7 days on conservative therapy. Risk of immunosuppression is very important to consider when giving steroids in patients with infection induced AIN, and steroids may have to be delayed until the active infection is completely controlled

Artificial Intelligence in Neuroradiology: A Review of Current Topics and Competition Challenges

There is an expanding body of literature that describes the application of deep learning and other machine learning and artificial intelligence methods with potential relevance to neuroradiology practice. In this article, we performed a literature review to identify recent developments on the topics of artificial intelligence in neuroradiology, with particular emphasis on large datasets and large-scale algorithm assessments, such as those used in imaging AI competition challenges. Numerous applications relevant to ischemic stroke, intracranial hemorrhage, brain tumors, demyelinating disease, and neurodegenerative/neurocognitive disorders were discussed. The potential applications of these methods to spinal fractures, scoliosis grading, head and neck oncology, and vascular imaging were also reviewed. The AI applications examined perform a variety of tasks, including localization, segmentation, longitudinal monitoring, diagnostic classification, and prognostication. While research on this topic is ongoing, several applications have been cleared for clinical use and have the potential to augment the accuracy or efficiency of neuroradiologists

Your love lifts me higher! The energizing quality of secure relationships

Three studies tested and confirmed the hypothesis that secure attachment relationships lead to feelings of security and energy, as well as willingness to explore. In Study 1, priming a secure attachment relationship increased felt energy. In Studies 2 and 3, felt energy mediated the effect of (primed) secure attachment relationships on willingness to explore. In Study 3, the effect of (primed) secure attachment relationships on felt energy and willingness to explore was independent of general positive affect. Secure attachments energize partners, thus enabling exploration
