Chemically Modified PPARγ mRNA Unleashes Adipogenic Potential in 3T3-L1-Predipocytes: An Approach for Accelerated Wound Healing.

Adipocytes play a crucial role in tissue regeneration, contributing to the restoration of damaged areas and modulating the inflammatory milieu. The modulation of gene expression through chemically modified PPARγ mRNA (PPARγ-modRNA) introduces a sophisticated approach to precisely control adipogenic processes. This study aims to explore the adipogenic potential of the PPARγ-modRNA in 3T3-L1 preadipocytes and its role in wound healing.

What is the impact of acute endocrine and metabolic alterations on long-term ischemic stroke prognosis: a prospective study.

Background: Post-stroke stress can trigger instant survival but its influence on long-term ischemic stroke outcomes remains controversial. Thus, we sought to explore the associations of acute post-stroke stress evidenced by endocrine and metabolic changes, with long-term ischemic stroke outcomes.

Methods: Admissions for acute ischemic stroke within seven days of onset were prospectively recruited to determine acute endocrine and metabolic variations measured by thyroid parameters and the stress hyperglycemia ratio (SHR).

Advanced technologies for the development of infectious disease vaccines.

Vaccines play a critical role in the prevention of life-threatening infectious disease. However, the development of effective vaccines against many immune-evading pathogens such as HIV has proven challenging, and existing vaccines against some diseases such as tuberculosis and malaria have limited efficacy. The historically slow rate of vaccine development and limited pan-variant immune responses also limit existing vaccine utility against rapidly emerging and mutating pathogens such as influenza and SARS-CoV-2.

Behenic acid alleviates inflammation and insulin resistance in gestational diabetes mellitus by regulating TLR4/NF-κB signaling pathway.

Gestational diabetes mellitus (GDM) is a distinct form of diabetes that poses a significant threat to the health of both pregnant women and fetuses. The objective of this study was to investigate the impact of behenic acid (BA) on glucose metabolism, inflammation, and insulin resistance in GDM mice, and to elucidate the underlying molecular mechanism. Here, we demonstrated that daily administration of 10 mg/mL BA during pregnancy effectively ameliorated abnormal glucose metabolism in GDM mice and their offspring and improved birth outcomes in the offspring.

Microglial DBP Signaling Mediates Behavioral Abnormality Induced by Chronic Periodontitis in Mice.

Several lines of evidence implicate that chronic periodontitis (CP) increases the risk of mental illnesses, such as anxiety and depression, yet, the associated molecular mechanism for this remains poorly defined. Here, it is reported that mice subjected to CP exhibited depression-like behaviors and hippocampal memory deficits, accompanied by synapse loss and neurogenesis impairment in the hippocampus. RNA microarray analysis disclosed that albumin D-site-binding protein (DBP) is identified as the most prominently upregulated target gene following CP, and in vivo and in vitro immunofluorescence methods showed that DBP is preferentially expressed in microglia but not neurons or astrocytes in the hippocampus.

Interpretable GWAS by linking clinical phenotypes to quantifiable immune repertoire components.

Bridging the gap between genotype and phenotype in GWAS studies is challenging. A multitude of genetic variants have been associated with immune-related diseases, including cancer, yet the interpretability of most variants remains low. Here, we investigate the quantitative components in the T cell receptor (TCR) repertoire, the frequency of clusters of TCR sequences predicted to have common antigen specificity, to interpret the genetic associations of diverse human diseases.

A randomized controlled educational study to evaluate an e-learning module to teach the physical examination of the temporomandibular joint in juvenile idiopathic arthritis.

Background: The aim of the study was to evaluate the effectiveness of a novel e-learning module in teaching the physical exam of the temporomandibular joint (TMJ) in Juvenile idiopathic arthritis (JIA.).

Methods: An e-learning module was developed to convey the TMJ physical examination maneuvers that are considered to be best practice in JIA.

Esophagitis, treatment outcomes, and long-term follow-up in children with esophageal atresia.

Objectives: Survival rates in children born with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) have improved; however, morbidity associated with the disease remains high. This study aimed to assess the prevalence of gastroesophageal reflux disease (GERD), eosinophilic esophagitis (EoE), fungal esophagitis, esophageal strictures, and long-term outcomes in children with EA/TEF.

Methods: We conducted a retrospective chart review on patients with EA/TEF who were seen at Children's Wisconsin from January 2003 to January 2023.

Assessing the Impact of Frailty on Infection Risk in Older Adults: Prospective Observational Cohort Study.

Background: Infectious diseases are among the leading causes of death and disability and are recognized as a major cause of health loss globally. At the same time, frailty as a geriatric syndrome is a rapidly growing major public health problem. However, few studies have investigated the incidence and risk of infectious diseases in frail older people.

Zinc Finger Protein 536 is a Potential Prognostic Biomarker that Promotes Neuroblastoma Progression via VEGFR2-PI3K-AKT Pathway.

Background: Neuroblastoma (NB) is a well-known pediatric malignancy intertwined with neurodevelopment. Previously implicated in neuronal differentiation, Zinc Finger Protein 536 (ZNF536) has emerged as a promising prognostic and immune-related biomarker in our pan-cancer analysis.

Methods: Single-cell RNA transcriptome sequencing, bulk transcriptome analysis, and immuno-histochemistry were used to assess ZNF536 expression and its association with prognosis.

Antibody-Mediated Nodo- and Paranodopathies.

The recent discovery of pathogenic antibodies targeting cell adhesion molecules of the node of Ranvier has prompted efforts to develop a new classification for a subset of antibody-mediated peripheral neuropathies. These autoimmune nodo- and paranodopathies encompass epitopes such as neurofascin 155, neurofascin 186, contactin-1, and contactin-associated protein 1, with a high likelihood of involving additional yet unidentified proteins. So far, the investigation of this subset of patients was primarily focused on adults, with only rare reports of pediatric cases.

Development of a carbohydrate-binding protein prediction algorithm using structural features of stacking aromatic rings.

Carbohydrate-protein interactions play fundamental roles in numerous aspects of biological activities, and the search for new carbohydrate (CHO)-binding proteins (CBPs) has long been a research focus. In this study, through the analysis of CBP structures, we identified significant enrichment of aromatic residues in CHO-binding regions. We further summarized the structural features of these aromatic rings within the CHO-stacking region, namely "exposing" and "proximity" features, and developed a screening algorithm that can identify CHO-stacking Trp (tryptophan) residues based on these two features.

A "Goldilocks Zone" for Recruiting BET Proteins with Bromodomain-1-Selective Ligands.

Synthetic genome readers/regulators (SynGRs) are bifunctional molecules that are rationally designed to bind specific genomic sequences and engage cellular machinery that regulates the expression of targeted genes. The prototypical SynGR1 targets GAA trinucleotide repeats and recruits the BET family of transcriptional regulatory proteins via a flexibly tethered ligand, JQ1. This pan-BET ligand binds both tandem bromodomains of BET proteins (BD1 and BD2).

Hsa_circ_0002473 inhibits GH3 cell proliferation and GH secretion as a competitive endogenous RNA for has-miR-4645-3p.

Growth hormone deficiency (GHD) diagnosis still lacks a gold standard or ideal diagnostic marker. Unlike other epigenetic mechanisms, non-coding RNAs regulate post-transcriptional levels. The information on non-coding RNAs in the field of GHD is limited.

Visual colorimetric label for real-time monitoring of SO concentration change in grape and mango during storage.

Sulfur dioxide (SO) is widely utilized as a preservative in food transportation and storage, but excessive consumption poses health risks. This study presents a novel and efficient method for the real-time detection of SO using a sensor named TK, synthesized from triphenylamine and 2-cyanomethyl-1-methyl-quinolinium. The core mechanism involves the Michael addition reaction of the CC bond in TK with SO, which disrupts the intramolecular charge transfer process, resulting in a significant color change and a blue shift in fluorescence emission.
