The TESS-Keck Survey. XI. Mass Measurements for Four Transiting sub-Neptunes orbiting K dwarf TOI-1246

Multi-planet systems are valuable arenas for investigating exoplanet architectures and comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf (V=11.6, K=9.9) and four transiting sub-Neptunes identified by TESS with orbital periods of 4.31 d, 5.90 d, 18.66 d, and 37.92 d. We collected 130 radial velocity observations with Keck/HIRES and TNG/HARPS-N to measure planet masses. We refit the 14 sectors of TESS photometry to refine planet radii (2.97±0.06 R⊕,2.47±0.08 R⊕,3.46±0.09 R⊕, 3.72±0.16 R⊕), and confirm the four planets. We find that TOI-1246 e is substantially more massive than the three inner planets (8.1±1.1M⊕, 8.8±1.2M⊕, 5.3±1.7M⊕, 14.8±2.3M⊕). The two outer planets, TOI-1246 d and TOI-1246 e, lie near to the 2:1 resonance (Pe/Pd=2.03) and exhibit transit timing variations. TOI-1246 is one of the brightest four-planet systems, making it amenable for continued observations. It is one of only six systems with measured masses and radii for all four transiting planets. The planet densities range from 0.70±0.24 to 3.21±0.44g/cm3, implying a range of bulk and atmospheric compositions. We also report a fifth planet candidate found in the RV data with a minimum mass of 25.6 ± 3.6 M⊕. This planet candidate is exterior to TOI-1246 e with a candidate period of 93.8 d, and we discuss the implications if it is confirmed to be planetary in nature

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Racism in Palliative Care Research: We Still Have a Ways to Go

This series focuses on addressing the intersection of race and racism in palliative care through roundtable discussions with interdisciplinary clinicians, researchers, educators, and leaders in palliative care. These short discussions are intended to stimulate readers to examine issues of race and racism within the field of hospice and palliative care - in the various forms that it appears - as well as serve as a continual call to action to facilitate and promote equity

The Dance of Cystic Fibrosis: Experiences of Living with Cystic Fibrosis as an Adult

Aim: This study sought to understand the experience of living with cystic fibrosis as an adult.Background: Cystic fibrosis is one of the most difficult chronic diseases to manage long‐term because of numerous challenges faced on a day‐to‐day basis. The majority of studies focus on improving symptom response to new treatment regimens with the hope of prolonging life. Yet few qualitative studies explore the experience of adults with cystic fibrosis. What is missing from the current literature are the voices of people living with cystic fibrosis, especially as they age.Design: This study follows a hermeneutic phenomenology design guided by Martin Heidegger’s philosophy.Methods: Semi‐structured interviews were conducted with 9 adults living with cystic fibrosis. Hermeneutic phenomenology guided the data interpretation. This manuscript follows COREQ reporting guidelines.Results: Hermeneutic analysis revealed the overarching theme The Dance of Cystic Fibrosis which is supported by five themes: 1) The Paradox of Control, 2) Living Deaths, 3) Dancing with Death, 4) Relearning to Dance, and 5) Role of the Dance Partner.Conclusions: The experience of living with cystic fibrosis as an adult is multidimensional and unique to each person. Despite the uniqueness, there is a shared experience that manifested as The Dance of Cystic Fibrosis . As life expectancy continues to increase for persons with cystic fibrosis, it is essential that researchers and healthcare professionals intentionally consider the life prolonging effects of the treatment regimen alongside the persons’ experience with those effects.Relevance to Clinical Practice: Nurses at all levels of practice should be prepared to address the multifaceted experience of living with cystic fibrosis through thoughtful incorporation of open‐ended questions. This allows patients to share their experience with nurses, augmenting their practice of delivering holistic care

Creating effective biocontainment facilities and maintenance protocols for raising specific pathogen-free, severe combined immunodeficient (SCID) pigs

Severe combined immunodeficiency (SCID) is defined by the lack of an adaptive immune system. Mutations causing SCID are found naturally in humans, mice, horses, dogs, and recently in pigs, with the serendipitous discovery of the Iowa State University SCID pigs. As research models, SCID animals are naturally tolerant of xenotransplantation and offer valuable insight into research areas such as regenerative medicine, cancer therapy, as well as immune cell signaling mechanisms. Large-animal biomedical models, particularly pigs, are increasingly essential to advance the efficacy and safety of novel regenerative therapies on human disease. Thus, there is a need to create practical approaches to maintain hygienic severe immunocompromised porcine models for exploratory medical research. Such research often requires stable genetic lines for replication and survival of healthy SCID animals for months post-treatment. A further hurdle in the development of the ISU SCID pig as a biomedical model involved the establishment of facilities and protocols necessary to obtain clean SPF piglets from the conventional pig farm on which they were discovered. A colony of homozygous SCID boars and SPF carrier sows has been created and maintained through selective breeding, bone marrow transplants, innovative husbandry techniques, and the development of biocontainment facilities. </jats:p
