    Abstract This article compares the learning outcomes and student perceptions of a one semester undergraduate biochemistry laboratory course that was taught using either a fully online or a fully in-person teaching modality. The semester long biochemistry laboratory mimicked the work sequence a researcher would encounter when transforming a plasmid containing a gene for a recombinant protein (superfolder green fluorescent protein, sf-GFP) and then purifying, identifying, and characterizing that protein. The two modalities of the course were completed in the same semester, by the same instructor, in which students self-selected into which modality they preferred at the beginning of the semester. Students in the in-person section reported enjoying the laboratory course more than the online cohort of students and found it to be less time-consuming. Additionally, a survey of biochemistry laboratory instructors from across the United States, who had experience teaching both online and in-person biochemistry laboratories, indicated that the majority of instructors that responded to the survey preferred the in-person modality: believing them to be more effective and engaging for the students, more enjoyable, and less time-consuming for the instructor. Statistical analysis of formative and summative assessments indicated no significant difference in non-hands-on student learning objective and learning goal scores between the two groups, but the small number of students and instructors in this study limits the generalizability of these results.

    Abstract The monkeypox (Mpox) virus has raised significant concerns given its recent spread with an increasing number of confirmed cases worldwide. In this study, we evaluated the performance of a laboratory developed test (LDT) using BioGX Xfree hMPXV/OPXV reagents for the qualitative detection of non-variola Orthopoxviruses and Mpox virus DNA, in swabs from human pustular or vesicular rash specimens. Analytical and clinical testing analysis were carried out on two different platforms: the BD MAX™ System (BD Diagnostics) and the new pixl.16 Real-Time PCR Platform (BioGX), using a synthetic Mpox virus DNA (ATCC VR-3270SD) and residual clinical samples previously identified with an EUA approved Mpox real-time PCR assay. In the end, the Xfree hMPXV/OPXV LDT proved to be a sensitive, specific, and reproducible test for the detection of Mpox on both platforms evaluated with the pixl.16 having an advantage of a small footprint and providing faster TAT facilitated by an extraction-free workflow.

    Abstract Background: Cytomegalovirus (CMV) infection has a major negative impact on transplantation and is associated with increased morbidity and mortality in this patient population. Quantitation of CMV infections using a molecular test is the preferred method for monitoring patients post-transplant. For this analysis, we compared the Aptima CMV Quant Assay (Aptima CMV) on the Panther system to the ELITech MGB Alert® CMV 3.0 ASR (MGB CMV) run on the ELITe InGenius®.
    Methods: The analytical performance of the assay was assessed using commercially available CMV reference panels that meet the 1st WHO International Standard for Human Cytomegalovirus for nucleic acid amplification techniques. The clinical performance of the assay was determined using 249 plasma and non-plasma samples.
    Results: The 95% LOD of the Aptima assay was determined to be 50 IU/mL and 200 IU/mL for the MGB CMV assay. A strong linear correlation with the reference panel (R
    Conclusion: The Aptima CMV assay is both sensitive and accurate in quantifying CMV in both plasma and non-plasma specimens on the fully automated Panther system.

    Abstract Background: Double-fortified salt (DFS) is a vehicle for dual fortification with iron and iodine, to reduce their respective deficiencies. This background article is the third in a series reviewing available research, analyses, and experiences on DFS as an effective delivery vehicle for iron and iodine.
    Objectives: The objective of this article is to systematically evaluate current programs distributing DFS around the world and catalogue opportunities, risks, and challenges related to programs that incorporate DFS. We carried out a narrative review of DFS programs from around the world with our data sources deriving from a mix of a nonsystematic literature search and interviews with key informants.
    Methods: We assessed programmatic experience with DFS from social safety net programs in India (from the states of Bihar, Madhya Pradesh, and Uttar Pradesh) and from non-social safety net country programs or projects in Argentina, Cote d'Ivoire, Kenya, Morocco, Nigeria, Philippines, and Sri Lanka.
    Results: Findings revealed color change of the final DFS product was an issue in 9 of the 14 programs or studies reviewed and was the most significant challenge that had a direct impact on consumer acceptance and uptake regardless of type of program (open market or social safety net). Other challenges identified were related to the quality of the salt and lack of DFS formulation standards and regulatory monitoring protocols.
    Conclusions: DFS programs need to focus on 1) improved technology with better consumer acceptance and better performance when used with lower-quality salt; 2) elucidation and enforcement of DFS formulation quality standards, along with producer incentives; and 3) strong government backing at the policy level. DFS offers a unique opportunity to leverage an almost universally consumed product with the addition of 2 important nutrients missing in many populations. However, program "maturity" will take time with urgent attention needed for quality production.

    Abstract Embedding behavioral health (EBH) personnel into operational units has emerged as a major trend within the US military. These positions require skillsets in addition to those needed in a clinic setting. Little or no empirically based training has yet been developed to ensure preparedness to serve in EBH roles. Based on the demonstrated effectiveness of situational judgment tests (SJT) in training for other domains, we developed and evaluated 60 SJT scenarios for use in the US Air Force's formal EBH training course. SJTs were based on real-world experiences of seasoned EBH professionals, and were used for structured, scenario-based discussions during training as well as a 30-item pre- and posttest to assess learning. Use during training was associated with significantly improved scores in six EBH competencies (ethical decision-making, leadership consultation, balancing professional relationships, unit engagement, triage to correct services, and teaming). In a follow-up survey, students reported scenario-based discussions were very helpful, and reported improved abilities and confidence. This study demonstrates the potential utility of the SJT methodology to prepare mental health professionals to serve in EBH positions. Further development and possible applications are discussed, such as expansion to other training venues, job candidate screening, and assessment for readiness for EBH practice.

    Abstract Addressing climate change and biodiversity loss will be the defining ecological, political, and humanitarian challenge of our time. Alarmingly, policymakers face a narrowing window of opportunity to prevent the worst impacts, necessitating complex decisions about which land to set aside for biodiversity preservation. Yet, our ability to make these decisions is hindered by our limited capacity to predict how species will respond to synergistic drivers of extinction risk. We argue that a rapid integration of biogeography and behavioral ecology can meet these challenges because of the distinct, yet complementary levels of biological organization they address, scaling from individuals to populations, and from species and communities to continental biotas. This union of disciplines will advance efforts to predict biodiversity's responses to climate change and habitat loss through a deeper understanding of how biotic interactions and other behaviors modulate extinction risk, and how responses of individuals and populations impact the communities in which they are embedded. Fostering a rapid mobilization of expertise across behavioral ecology and biogeography is a critical step toward slowing biodiversity loss.

    Abstract The origin and early evolution of life is generally studied under two different paradigms: bottom up and top down. Prebiotic chemistry and early Earth geochemistry allow researchers to explore possible origin of life scenarios. But for these "bottom-up" approaches, even successful experiments only amount to a proof of principle. On the other hand, "top-down" research on early evolutionary history is able to provide a historical account about ancient organisms, but is unable to investigate stages that occurred during and just after the origin of life. Here, we consider ancient electron transport chains (ETCs) as a potential bridge between early evolutionary history and a protocellular stage that preceded it. Current phylogenetic evidence suggests that ancestors of several extant ETC components were present at least as late as the last universal common ancestor of life. In addition, recent experiments have shown that some aspects of modern ETCs can be replicated by minerals, protocells, or organic cofactors in the absence of biological proteins. Here, we discuss the diversity of ETCs and other forms of chemiosmotic energy conservation, describe current work on the early evolution of membrane bioenergetics, and advocate for several lines of research to enhance this understanding by pairing top-down and bottom-up approaches.

    Abstract With multiple food fortification frameworks, countries can find it challenging to determine optimal methods for planning and implementing food fortification programmes to combat vitamin and mineral deficiencies, especially without additional technical support. To address this challenge, this study aimed to review existing frameworks to determine consistencies, differences, strengths, and weaknesses across the frameworks, and based on the review findings, formulate an enhanced and streamlined fortification framework. Nineteen frameworks were ultimately examined following a comprehensive literature review and key informant interviews. Generally, the reviewed frameworks amply describe motives and methods for the determination of fortification need and feasibility, industry engagement/quality assurance and quality control, and impact evaluations/surveillance. However, there was limited inclusion or discussion throughout the reviewed frameworks around harmonization of fortification with existing micronutrient interventions; fortification policy and/or strategy; enforcement, incentives, and penalties to ensure producer compliance with industry standards; and periodic fortification programme review and reassessment. The findings were used to develop a comprehensive Fortification Blueprint that aims to provide structured guidance and a library of tools and resources to fortification programme managers and key stakeholders to ensure optimal and sustainable programme design.

    Abstract Birds that breed opportunistically maintain partial activation of reproductive systems to rapidly exploit environmental conditions when they become suitable for breeding. Maintaining reproductive systems outside of a breeding context is costly. For males, these costs are thought to include continual exposure to testosterone. Males of seasonally breeding birds minimise these costs by downregulating testosterone production outside of a breeding context. Opportunistically breeding birds trade off the need to rapidly initiate reproduction with the costs of elevated testosterone production. One way opportunistically breeding males could minimise these costs is through fine scale changes in testosterone production across discrete reproductive stages which have a greater or lesser requirement for active sperm production. Although spermatogenesis broadly depends on testosterone production, whether changes in testosterone levels across the reproductive stages affect sperm quality and production is unknown. Here, we measured testosterone, sperm quality, and body condition in male zebra finches at discrete stages within reproductive bouts (egg laying, incubation, nestling provisioning, and fledging) and across two consecutive reproductive events in captive male zebra finches (Taeniopygia castanotis). We also examined associations between male testosterone, sperm quality/production, body condition, and nestling body condition. We found that testosterone levels varied across discrete reproductive stages with the lowest levels during incubation and the highest following chick fledging. Testosterone levels were positively associated with sperm velocity and the proportion of motile sperm but were not associated with male body condition. We found no associations between paternal body condition, testosterone levels, or sperm traits with nestling body condition (a proxy for the reproductive quality of a male and his partner). This study is the first to show that opportunistically breeding males vary testosterone synthesis and sperm traits at discrete stages within a reproductive event.
