Article Synopsis
  • The medial frontal cortex (mFC) and locus coeruleus (LC) are brain regions linked to cognitive functions like attention, memory, and decision-making, yet their molecular regulators remain unclear.
  • Using chemogenetic stimulation in mice, the study found that activating LC neurons targeting the mFC led to increased gene transcription, especially in GABAergic neurons related to cognitive functions.
  • The research highlights the role of specific gene expression as potential biomarkers for neuropsychiatric disorders like ADHD, schizophrenia, and Alzheimer's, aiming to inform treatments for cognitive and behavioral symptoms.

Cyanobacteria are highly abundant in the marine photic zone and primary drivers of the conversion of inorganic carbon into biomass. To date, all studied cyanobacterial lineages encode carbon fixation machinery relying upon form I Rubiscos within a CO-concentrating carboxysome. Here, we report that the uncultivated anoxic marine zone (AMZ) IB lineage of from pelagic oxygen-deficient zones (ODZs) harbors both form I and form II Rubiscos, the latter of which are typically noncarboxysomal and possess biochemical properties tuned toward low-oxygen environments.

Article Synopsis
  • - Maternal smoking during pregnancy has notable negative effects on the cognitive and behavioral development of offspring, with this study specifically comparing the impacts of nicotine and cigarette smoke on gene expression in developing brains.
  • - Researchers found a significant number of differentially expressed genes (1,010 for nicotine and 4,165 for smoking) linked to prenatal exposure, indicating different neurodevelopmental pathways affected by each substance.
  • - The findings suggest that while both prenatal nicotine exposure and maternal smoking have specific and overlapping effects on the developing brain, these effects are not replicated in the adult brain, highlighting developmental-stage sensitivity to smoke-related changes.

Background: The triglyceride (TG) content of low-density lipoprotein (LDL-TG) has been shown to be more predictive of atherosclerotic cardiovascular disease (ASCVD) events than the cholesterol content of LDL (LDL-C). The goal of our study was to develop an equation for estimating LDL-TG (LDL-TG) based on the standard lipid panel and to compare it to estimated LDL-C as an ASCVD risk biomarker.

Methods: Using least-square regression analysis, the following LDL-TG equation was developed: .

Urea is hypothesized to be an important source of nitrogen and chemical energy to microorganisms in the deep sea; however, direct evidence for urea use below the epipelagic ocean is lacking. Here, we explore urea utilization from 50 to 4000 meters depth in the northeastern Pacific Ocean using metagenomics, nitrification rates, and single-cell stable-isotope-uptake measurements with nanoscale secondary ion mass spectrometry. We find that on average 25% of deep-sea cells assimilated urea-derived N (60% of detectably active cells), and that cell-specific nitrogen-incorporation rates from urea were higher than that from ammonium.

In recent years, a small number of people with rare diseases caused by unique genetic variants have been treated with therapies developed specifically for them. This pioneering field of genetic N-of-1 therapies is evolving rapidly, giving hope for the individualized treatment of people living with very rare diseases. In this Review, we outline the concept of N-of-1 individualized therapies, focusing on genetic therapies, and illustrate advances and challenges in the field using cases for which therapies have been successfully developed.

Article Synopsis
  • Cystic fibrosis outpatient care has shifted to a hybrid model, integrating telehealth and in-person visits, and this study evaluates how acceptable this model is for those affected by CF and their parents.
  • Semi-structured interviews were conducted with a diverse group of participants across Australia, focusing on their experiences and perceptions of this hybrid care approach using the Theoretical Framework of Acceptability (TFA).
  • Key findings show that while participants appreciate the convenience and safety of hybrid care, they also express concerns about losing valued elements of traditional face-to-face interactions, highlighting the importance of personalizing the care model to meet individual needs.

To date, most sexual assault research has focused on specific perpetrator tactics, including verbal coercion, substance-related incapacitation, and force. Responding to recent calls to assess a broader range of nonconsensual sexual experiences, we examined the occurrence and outcomes of sexual assault without warning - when a perpetrator "just does" a behavior without giving a chance to say "no." Participants were 850 college students (M = 19.

Background: Cardiac troponin (cTn) is key in diagnosing myocardial infarction (MI). After MI, the clinically observed half-life of cTn has been reported to be 7 to 20 hours, but this estimate reflects the combined elimination and simultaneous release of cTn from cardiomyocytes. More precise timing of myocardial injuries necessitates separation of these 2 components.

We show that substitutional alloying during the aqueous self-assembly of layered organic-templated metal oxides produces single-phase mixed-metal hybrids. Single-crystal X-ray diffraction, bulk elemental analyses, and vibrational and electronic spectroscopies corroborate a solid solution of Mo and W atoms at lattice sites within the two-dimensional metal oxide layers. Mild postsynthetic reduction then introduces relatively delocalized electrons to afford mixed-metal hybrid bronzes.
