A novel sustained-release agent based on disulfide-induced recombinant collagen hydrogels for the prevention and treatment of infections.

Schistosomiasis is commonly managed using the praziquantel, but it is only effective against adult worms and duration of action is short. Liver fibrosis will worsen if eggs are still present after stopping treatment. Therefore, this study aimed to develop a sustained drug release system for effectively preventing and treating schistosomiasis.

Prevotellaceae Modulates Colorectal Cancer Immune Microenvironment to Assist Anti-PD-L1 Immunotherapy.

Background/aims: Colorectal cancer (CRC) stands as the third most prevalent cancer on a global scale. In recent years, immunotherapy, such as anti-PD-L1 treatment, has demonstrated promising therapeutic outcomes in CRC. However, studies have suggested that intestinal microbiota may influence the efficacy of anti-PD-L1 immunotherapy.

The primate gut microbiota contributes to interspecific differences in host metabolism.

Because large brains are energetically expensive, they are associated with metabolic traits that facilitate energy availability across vertebrates. However, the biological underpinnings driving these traits are not known. Given its role in regulating host metabolism in disease studies, we hypothesized that the gut microbiome contributes to variation in normal cross-vertebrate species differences in metabolism, including those associated with the brain's energetic requirements.

Combining azole antifungals with venetoclax plus azacitidine in patients with newly diagnosed acute myeloid leukemia.

The combination of venetoclax (VEN) with hypomethylating agents (HMAs) improves survival in patients with acute myeloid leukemia (AML) and may cause neutropenia requiring combined antifungal therapy or prophylaxis. The inhibition of cytochrome P450 activity by azole antifungal agents leads to elevated blood concentrations of VEN. This study aimed to evaluate the efficacy and safety of venetoclax plus azacitidine (AZA) with azoles in newly diagnosed AML patients.

Ginsenoside Rg1 reduces cardiac inflammation against myocardial ischemia/reperfusion injury by inhibiting macrophage polarization.

Background: Myocardial ischemia/reperfusion (MI/R) injury is the main cause of death worldwide and poses a significant threat to cardiac health. Ginsenoside Rg1 has been shown to have inhibitory effects on inflammatory activation, oxidative stress, and cardiac injury, suggesting that Rg1 may have therapeutic effects on MI/R injury. However, the mechanism remains to be further studied.

Exploring the efficacy and safety of laser interstitial thermal therapy for recurrent high-grade glioma: the first prospective cohort in China.

Objective: Recurrent high-grade gliomas are complicated cancers that require additional treatment options. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) is a safe method for treating recurrent high-grade glioma; however, its use in China has not been reported. In this study, we aimed to investigate the safety and efficacy of an MRgLITT system (SinoVision™) developed in China for treating recurrent high-grade glioma.

Peierls Distortion Induced Giant Linear Dichroism, Second-Harmonic Generation, and In-Plane Ferroelectricity in NbOBr.

The Peierls distortion plays an essential role in governing the in-plane ferroelectricity and nonlinear optical characteristics of anisotropic niobium oxide dihalides, such as NbOCl and NbOI. Despite its significance, experimental investigation into the structural, optical, and ferroelectric properties of NbOBr has been lacking. Here, the successful fabrication of centimeter-sized, high-quality NbOBr single crystals, enabling direct observation of Peierls distortion using aberration-corrected scanning transmission electron microscopy, is reported.

Huangqi-Danshen decoction improves heart failure by regulating pericardial adipose tissue derived extracellular vesicular miR-27a-3p to activate AMPKα2 mediated mitophagy.

Background: Huangqi-Danshen decoction (HDD) is a classic traditional Chinese medicine for treating heart failure. Pericardial adipose tissue (PAT) has recently gained increasing attention in cardiovascular diseases.

Purpose: This study aimed to investigate the effect of pericardial adipose tissue-derived extracellular vesicles on heart failure, the protective effect of HDD on myocardial remodel in heart failure rats, and identify the potential molecular mechanisms involved.

The relationship between leptin-to-adiponectin ratio and HOMA-IR and metabolic syndrome in five African-origin populations.

Objective: This cross-sectional study aims to assess the associations between serum leptin, adiponectin, leptin-to-adiponectin ratio (L/A ratio), and metabolic syndrome (MS) and HOMA-IR in five African-origin populations: Ghana, South Africa, Jamaica, Seychelles, and US.

Methods: Clinical measures included serum glucose, insulin, adipokines, blood pressure and anthropometric measures. MS was determined using the Harmonized criteria.

Predicting Prenatal Depression and Assessing Model Bias Using Machine Learning Models.

Background: Perinatal depression is one of the most common medical complications during pregnancy and postpartum period, affecting 10% to 20% of pregnant individuals, with higher rates among Black and Latina women who are also less likely to be diagnosed and treated. Machine learning (ML) models based on electronic medical records (EMRs) have effectively predicted postpartum depression in middle-class White women but have rarely included sufficient proportions of racial/ethnic minorities, which has contributed to biases in ML models. Our goal is to determine whether ML models could predict depression in early pregnancy in racial/ethnic minority women by leveraging EMR data.

Senescent CD8+ T cells: a novel risk factor in atrial fibrillation.

Aims: Immune cell alterations may play a role in the development of atrial fibrillation (AF). Our objective was to comprehensively characterize immune cells in AF, and investigate the potential mechanisms.

Methods And Results: Single-cell RNA sequencing and multicolor flow cytometry revealed that T cells constituted the most significant subset alterations in AF, and senescent CD8+ T cells were AF-associated subset.

Temperature distribution inversion in infrared multispectral imaging based on ensemble network.

Temperature distribution can be acquired through non-contact temperature measurement using multispectral imaging. However, the challenge lies in radiometric temperature inversion owing to the unknown emissivity. Despite the promising results demonstrated by traditional algorithms and neural networks, enhancing the precision and reliability of temperature inversion remains a challenge.

The value of phenylalanine in predicting atrial fibrillation risk in chronic heart failure.

Backgrounds: Atrial fibrillation (AF) is a common complication of chronic heart failure (HF). Serum phenylalanine (Phe) levels are related to inflammation disorder. It is meaningful to study the circulating Phe with AF occurrence in HF.

Farnesyltransferase-inhibitors exert immunosuppressive capacity by inhibiting human B-cells.

Objectives: Farnesyltransferase inhibitors (FTI), which inhibit the prenylation of Ras GTPases, were developed as anti-cancer drugs. As additional target proteins for prenylation were identified in the past, it is likely that FTI have potential value for therapeutic purposes beyond cancer. The effect of FTI on B-cells remains unclear.
