Simulated deep space exposure on seeds utilizing the MISSE flight facility.

The MISSE-Seed project was designed to investigate the effects of space exposure on seed quality and storage. The project tested the Multipurpose Materials International Space Station Experiment-Flight Facility (MISSE-FF) hardware as a platform for exposing biological samples to the space environment outside the International Space Station (ISS). Furthermore, it evaluated the capability of a newly designed passive sample containment canister as a suitable exposure unit for biological samples for preserving their vigor while exposing to the space environment to study multi-stressor effects.

SAMHD1 shapes deoxynucleotide triphosphate homeostasis by interconnecting the depletion and biosynthesis of different dNTPs.

SAMHD1 is a dNTPase that impedes replication of HIV-1 in myeloid cells and resting T lymphocytes. Here we elucidate the substrate activation mechanism of SAMHD1, which involves dNTP binding at allosteric sites and transient tetramerization. Our findings reveal that tetramerization alone is insufficient to promote dNTP hydrolysis; instead, the activation mechanism requires an inactive tetrameric intermediate with partially occupied allosteric sites.

Neutralizing antibody immune correlates in COVAIL trial recipients of an mRNA second COVID-19 vaccine boost.

Neutralizing antibody titer has been a surrogate endpoint for guiding COVID-19 vaccine approval and use, although the pandemic's evolution and the introduction of variant-adapted vaccine boosters raise questions as to this surrogate's contemporary performance. For 985 recipients of an mRNA second bivalent or monovalent booster containing various Spike inserts [Prototype (Ancestral), Beta, Delta, and/or Omicron BA.1 or BA.

NKAPL facilitates transcription pause-release and bridges elongation to initiation during meiosis exit.

Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes.

MnSOD non-acetylation mimic knock-in mice exhibit dilated cardiomyopathy.

Manganese superoxide dismutase (MnSOD/SOD2) is an essential mitochondrial enzyme that detoxifies superoxide radicals generated during oxidative respiration. MnSOD/SOD2 lysine 68 acetylation (K68-Ac) is an important post-translational modification (PTM) that regulates enzymatic activity, responding to nutrient status or oxidative stress, and elevated levels have been associated with human illness. To determine the in vivo role of MnSOD-K68 in the heart, we used a whole-body non-acetylation mimic mutant (MnSOD) knock-in mouse.

A randomized controlled trial to assess whether a telehealth-based contingency management intervention reduces alcohol use for individuals with alcohol use disorder.

Background: Contingency management (CM) is an intervention for alcohol use disorder (AUD) that reinforces abstinence, as confirmed by alcohol biomarkers. CM is usually brief (12-16 weeks) despite evidence that longer interventions have better long-term outcomes. Most CM models are in-person which can also be a barrier for treatment.

Survival outcomes comparing minimally invasive versus open cytoreductive surgery in recurrent adult-type granulosa cell tumors.

Background: Adult-type granulosa cell tumors are a rare form of ovarian cancer, 30% of which will recur. Cytoreductive surgery is often performed at the time of a first recurrence, but little is known about the impact of open versus minimally invasive surgical approaches on survival outcomes.

Objective: To examine associations between surgical approach, clinical variables, and survival outcomes among patients with adult-type granulosa cell tumors who underwent cytoreductive surgery at the time of first recurrence.

Bi-allelic KICS2 mutations impair KICSTOR complex-mediated mTORC1 regulation, causing intellectual disability and epilepsy.

Nutrient-dependent mTORC1 regulation upon amino acid deprivation is mediated by the KICSTOR complex, comprising SZT2, KPTN, ITFG2, and KICS2, recruiting GATOR1 to lysosomes. Previously, pathogenic SZT2 and KPTN variants have been associated with autosomal recessive intellectual disability and epileptic encephalopathy. We identified bi-allelic KICS2 variants in eleven affected individuals presenting with intellectual disability and epilepsy.

Creating a collaborative culture of learning within a network of community mental health early psychosis programs in Texas.

Learning Health Systems (LHSs) promise meaningful health care improvement through the ongoing use of data, including the lived experience of diverse constituents, such as people participating in and providing services. Most LHSs operate within a specific healthcare system, typically hospital-based, under a common electronic health record (EHR) and management structure. The Early Psychosis Intervention Network in Texas (EPINET-TX) is a novel case study of a developing LHS across 16 independent community mental health clinics operating state-funded coordinated specialty care (CSC) programs for early psychosis.

An Examination of predictors of prospective changes in self-reported drinker identity and changes in drinker identity as a predictor of changes in alcohol use and associated consequences.

Purpose: Self-reported drinker identity, the extent to which one views oneself as a drinker, is associated with alcohol consumption and related harms in young adults. The current study examined changes in self-reported drinker identity, theoretically relevant factors associated with drinker identity development, and drinker identity's association with changes in drinking and alcohol-related consequences. We hypothesized that drinker identity would increase over time; theoretically relevant factors would be significantly and positively associated with that increase, and increases in drinking identity would be associated with elevated drinking and related consequences.

Different social experiences drive the development of divergent stress coping styles in female swordtails (Xiphophorus nigrensis).

Individual variation in stress coping styles is widespread and consequential to health and fitness. Proactive (bold behavior, low stress reactivity, low cognitive flexibility) and reactive (shy behavior, high stress reactivity, high cognitive flexibility) coping styles are found in many species, but the developmental forces shaping them remain elusive. We examined how social influences, specifically mating interactions, shape the development of adult female coping styles with a manipulative rearing experiment using El Abra swordtails, Xiphophorus nigrensis.

The effect of the foreign body response on drug elution from subdermal delivery systems.

Contrasting findings are presented in the literature regarding the influence of foreign body response (FBR) on drug release from implantable drug delivery systems. To this end, here we sought direct evidence of the effect of the fibrotic tissue on subcutaneous drug release from long-acting drug delivery implants. Specifically, we investigated the pharmacokinetic impact of fibrotic encapsulation on a small molecule drug, islatravir (293 Da), and a large protein, IgG (150 kDa), administered via biocompatible implants.
