Pain as a driver of myocardial injury in hip fracture patients: a HIP fracture Accelerated surgical TreaTment And Care track (HIP ATTACK) Trial secondary analysis

1 week 5 days ago
CONCLUSION: Increased pain may be associated with myocardial ischemic events in the perioperative period in hip fracture patients. Future research is needed to confirm and further clarify this relationship, and to determine whether analgesic interventions can reduce the risk of perioperative myocardial ischemia.

Improving a photosynthetic bioprocess with a ubiquitous additive: Using clay powder in the cultivation of <em>Rhodopseudomonas palustris</em>

1 week 6 days ago
A key challenge in process optimization is reactor performance, particularly in light-dependent bioprocesses. While novel photobioreactor designs exist, adapting established bioreactors with simple media supplementation may provide a more practical and modular alternative to complex mechanical modifications. In this study, we evaluated the effect of supplementing 0.2 % (w/v) clay powder on acetate production by Rhodopseudomonas palustris grown on butyrate. Among the clay types tested, kaolin...

Automating quantum computing laboratory experiments with an agent-based AI framework

1 week 6 days ago
Fully automated self-driving laboratories promise high-throughput, large-scale scientific discovery by reducing repetitive labor. However, they require deep integration of laboratory knowledge, which is often unstructured, multimodal, and hard to incorporate into current AI systems. This paper introduces the "k-agents" framework, designed to support experimentalists in organizing laboratory knowledge and automating experiments with agents. The framework uses large-language-model-based agents to...

Cell networks in the mouse liver during partial hepatectomy

2 weeks 2 days ago
In solid tissues, homeostasis and post-injury regeneration involve a complex interplay among various cell types. The mammalian liver harbors numerous epithelial and non-epithelial cells, and the global signaling networks governing their interactions are unknown. To unravel the hepatic cell network, we purified 10 different cell populations from normal and regenerative mouse livers. Analyzing their transcriptomes unveiled ligand-receptor interactions and over 50,000 potential cell-cell...

Transcranial direct current stimulation restores addictive behavior via prefrontal-striatal circuit

2 weeks 2 days ago
Dependence on methamphetamine (METH) is a severe brain disorder characterized by high relapse rates and cognitive decline following detoxification. Recent research suggests that transcranial direct current stimulation (tDCS) may treat addiction, but the underlying neural mechanisms remain unknown. Here, we employed METH-conditioned place preference (CPP) paradigm integrated with fMRI, electrophysiology, chemogenetics, in vivo fiber photometry recordings and a novel rodent tDCS model to examine...

Computational design and evaluation of optimal bait sets for scalable proximity proteomics

2 weeks 4 days ago
The spatial organization of proteins within eukaryotic cells underlies essential biological processes and can be mapped by identifying nearby proteins using proximity-dependent biotinylation approaches such as BioID. When applied systematically to hundreds of bait proteins, BioID has localized thousands of endogenous proteins in human cells, generating a comprehensive view of subcellular organization. However, the need for large bait sets limits the scalability of BioID for context-dependent...

GraphComm predicts cell cell communication using a graph based deep learning method in single cell RNA sequencing data

2 weeks 4 days ago
Interactions between cells coordinate various functions across cell-types in health and disease states. Novel single-cell techniques enable deep investigation of cellular crosstalk at single-cell resolution. Cell-cell communication (CCC) is mediated by underlying gene-gene networks, however most current methods are unable to account for complex interactions within the cell as well as incorporate the effect of pathway and protein complexes on interactions. This results in the inability to infer...

The Genome Sequence of the Hemlock Woolly Adelgid, Adelges tsugae Annand 1924

2 weeks 4 days ago
The genome of the hemlock woolly adelgid (Adelges tsugae) is presented in 10 chromosomal pseudomolecules along with 132 unplaced scaffolds for a combined length of 216.56 Mb. The genome is highly contiguous with an N50 of 20.54 Mb and its longest scaffold 37.41 Mb in length. The assembly recovered 97.7% of benchmarked universal single-copy Hemiptera orthologs (BUSCO) with an overall completion score of 98.6%. On the basis of chromosomal synteny with other aphid genomes, the hemlock woolly...

Examining the Direct and Indirect Effects of Socioeconomic Status on Colorectal Cancer Using Structural Equation Modeling

2 weeks 6 days ago
The direct and indirect effects of socioeconomic status (SES) on colorectal cancer (CRC) were examined using structural equation modeling in a case-control study with 488 CRCs and 651 controls. SES was measured by education, income and resident region. SES (odds ratio (OR)=0.89), age (OR = 1.03), processed meat intake (OR = 1.08), lack of CRC screening (OR = 2.67), smoking (OR = 1.85) and family history (OR = 1.06) were significantly associated with CRC risk. SES had a direct effect on CRC risk...

Sequence-based prediction of condensate composition reveals that specificity can emerge from multivalent interactions among disordered regions

3 weeks 5 days ago
While specificity of biomolecular interactions is typically understood to require interactions involving ordered structures, several biomolecular condensates exhibit specificity in the absence of apparent structural order. We have previously shown that condensates composed of the disordered region of MED1 partition specific proteins, mediated by sequence patterns of charged amino acids on the disordered regions of both MED1 and the interacting partner. Whether this specificity is due to an...

From sediment sinks to ice sinks: Differential phase partitioning of PAH derivatives in a cold-climate aquatic ecosystem

3 weeks 6 days ago
The environmental risks of PAHs are well-documented, yet far less is known about their more toxic and persistent derivatives, MePAHs and NPAH, especially in the unique context of seasonally frozen wetlands. This study provides the first evidence of MePAHs and NPAHs enrichment in ice within a temperate wetland, based on their distribution behavior, migration behavior, and associated environmental risks in the Songhua River. Using GC-MS/MS quantification combined with ice enrichment factors (IEFs)...

Towards a reference cell atlas of liver diversity over the human lifespan

3 weeks 6 days ago
The goal of the Human Liver Cell Atlas (HLiCA) is to create a comprehensive map that defines the normal functions of diverse liver cell types and their spatial relationships over the human lifespan. This project fits within the goals of the Human Cell Atlas to create comprehensive reference maps of all human cells as a basis for both understanding human health and diagnosing, monitoring and treating disease. Through collection of samples from diverse individuals, data integration across...

The gut microbiome and child and adolescent depression and anxiety: a systematic review and meta-analysis with youth consultation

3 weeks 6 days ago
Decreased gut microbial diversity is associated with greater depression symptoms in adults. Findings on the relationship between the gut microbiome and depression or anxiety in children and adolescents are mixed, and evidence syntheses are needed. Seven databases were searched for peer-reviewed studies on the gut microbiome and internalizing symptoms, depression, or anxiety, in children and adolescents (<19 years). Random-effects meta-analyses of alpha diversity indices were performed. Youth...
