M2 macrophage-derived extracellular vesicles (M2-EVs) demonstrate the capacity to reduce pro-inflammatory M1 macrophage formation, thereby restoring the M1-M2 macrophage balance and promoting immunoregulation. However, the efficacy of M2-EVs in regulating macrophage polarization and subsequently enhancing osseointegration around titanium (Ti) implants in patients with diabetes mellitus (DM) remains to be elucidated. In this study, Ti implants were coated with polydopamine to facilitate M2-EVs adherence.

Nitrogen and sulfur co-doped carbon dots (N, S-CDs) were prepared for dual-channel ratiometric fluorescence determination of mercury ions (Hg). The dual-emission N, S-CDs were synthesized using a simple one-pot hydrothermal treatment. When excited with visible light, N,S-CDs exhibited two emission peaks at 390 and 500 nm.

Background: Distinguishing benign from malignant sub-centimeter solid pulmonary nodules (SSPNs) continues to be challenging in clinical practice. Earlier diagnosis is crucial for improving patient survival and prognosis. This study aimed to investigate the risk factors of malignant SSPNs and establish and validate a prediction model based on computed tomography (CT) characteristics to assist in their early diagnosis.

Article Synopsis
  • The study aimed to analyze the radiological characteristics of primary pulmonary invasive mucinous adenocarcinoma (IMA) to enhance understanding and improve initial diagnostic accuracy.
  • Researchers reviewed data from 312 patients with confirmed IMA, categorizing tumors based on morphology and density, and used statistical tests for analysis.
  • Findings indicated that IMA mostly occurs in older women, predominantly in the lower lung lobe, with regular nodule/mass and solid types being the most common, and identified key radiological features that can help differentiate IMA from other conditions.

The segment misalignment is a common defect in the segment installation of a shield tunnel construction, due to the complexity and uncertainty of its construction conditions. This raises a concerning about the safety of the segment lining for the shield tunnel. In this paper, the integrated numerical models with surrounding rock, peastone grouting and segment lining were built using three-dimensional finite element method, by introducing two kinds of misaligned defects of segments.

Expansin is a cell wall relaxant protein that is common in plants and directly or indirectly participates in the whole process of plant root growth, development and morphogenesis. A well-developed root system helps plants to better absorb water and nutrients from the soil while effectively assisting them in resisting osmotic stress, such as salt stress. In this study, we observed and quantified the morphology of the roots of overexpressing the gene obtained by the research group in the early stage of development.

As a type of cell-wall-relaxing protein that is widely present in plants, expansins have been shown to actively participate in the regulation of plant growth and responses to environmental stress. Wild soybeans have long existed in the wild environment and possess abundant resistance gene resources, which hold significant value for the improvement of cultivated soybean germplasm. In our previous study, we found that the wild soybean expansin gene is specifically transcribed in roots, and its transcription level significantly increases under salt and drought stress.

Article Synopsis
  • This study aimed to develop a deep learning model to differentiate benign from malignant subcentimeter solid pulmonary nodules (SSPNs) using CT images, addressing challenges in diagnosis.
  • The research involved a retrospective analysis of patients with confirmed SSPNs, employing a self-supervised model trained on existing databases and later fine-tuned with an internal dataset.
  • Results showed the model performed well, with high accuracy, sensitivity, and specificity in both internal and external testing cohorts, suggesting it could enhance patient management in clinical settings.

Objective: To determine whether quantitative parameters of detector-derived dual-layer spectral computed tomography (DLCT) can reliably identify epidermal growth factor receptor (EGFR) mutation status in patients with non-small cell lung cancer (NSCLC).

Methods: Patients with NSCLC who underwent arterial phase (AP) and venous phase (VP) DLCT between December 2021 and November 2022 were subdivided into the mutated and wild-type EGFR groups following EGFR mutation testing. Their baseline clinical data, conventional CT images, and spectral images were obtained.

Background: This study aimed to investigate the radiological, pathological, and prognostic characteristics of large consolidative-type pulmonary invasive mucinous adenocarcinomas (IMA).

Methods: We retrospectively reviewed 738 patients who confirmed IMA between January 2010 and August 2022, and two radiologists reviewed imaging data to determine subtypes. We included 41 patients with pathologically large consolidative-type IMA.

Statement Of Problem: There is currently no consensus on the relationship between maxillary anterior teeth and different facial anthropometric measurements. Additionally, whether these relationships vary by age and sex remains unreported.

Purpose: This clinical study aimed to investigate the relationship between the intercanine distance (ICaD) and intercanthal distance (ICD), interpupillary distance (IPD), interalar width (IAW), and intercommissural width (ICW), and to compare whether these relationships differ between different age and sex populations.

Article Synopsis
  • Universal stress proteins (USPs) are crucial for helping plants cope with abiotic stress, and this study specifically focused on the StUSP gene family in potatoes, which are vulnerable to damage and pathogens.
  • The research identified 108 USP genes in the Atlantic potato and categorized them into four subgroups, analyzing their genetic traits and conservation with similar species.
  • Findings from RNA-seq and gene coexpression analyses suggest that certain StUSP genes play vital roles in responding to stress, particularly in defense against pathogens and hormone signaling, laying the groundwork for future studies on their functions.

Background: We aimed to develop a combined model based on radiomics and computed tomography (CT) imaging features for use in differential diagnosis of benign and malignant subcentimeter (≤ 10 mm) solid pulmonary nodules (SSPNs).

Methods: A total of 324 patients with SSPNs were analyzed retrospectively between May 2016 and June 2022. Malignant nodules (n = 158) were confirmed by pathology, and benign nodules (n = 166) were confirmed by follow-up or pathology.

Objective: To investigate the effects of gastrodin on the biological behavior of osteoblasts and osseointegration on the surface of the titanium plate in a high glucose environment, and to explore the possible regulatory mechanisms involved.

Methods: A high glucose-induced oxidative damage model of MC3T3-E1 cells was established to observe the effects of gastrodin on cellular oxidative stress, cell viability, osteogenic differentiation, mineralization, migration, and adhesion ability on the titanium surface.

Results: High glucose environment can cause oxidative stress damage to MC3T3-E1 cells, leading to a decrease in cell viability, osteogenesis, migration, adhesion and other functions.

Gastrodin is an extract from the dried tuber of the Chinese herb (), with anti-inflammatory, antioxidant, and antiviral properties. Recent studies have shown that, compared to commonly used diabetes drugs, gastrodin has antidiabetic effects in multiple ways, with characteristics of low cost, high safety, less side effects, protection of β-cell function, relieving insulin resistance and alleviating multiple complications. In addition, it is confirmed that gastrodin can protect the function of lung and other organs, enhance antiviral activity via upregulating the type I interferon (IFN-I), and inhibit angiotensin II (AngII), a key factor in "cytokine storm" caused by COVID-19.
