Soil acidification represents a severe threat to tobacco cultivation regions in South China, exacerbating bacterial wilt caused by . The comprehension of the underlying mechanisms that facilitate the restoration of rhizosphere microbial communities in "healthy soils" is imperative for ecologically managing tobacco bacterial wilt. This study focuses on acidified tobacco soils that have been subjected to continuous cultivation for 20 years.

Article Synopsis
  • - The multi-attention guided UNet (MAUNet) is proposed for improved segmentation of thyroid nodules, addressing challenges due to their varying sizes and positions using a multi-scale cross attention (MSCA) module for better feature extraction.
  • - A dual attention (DA) module enhances information sharing between the encoder and decoder in the UNet architecture, further refining segmentation results.
  • - Extensive tests on ultrasound images from 17 hospitals reveal that MAUNet achieves high Dice scores (around 0.9) and outperforms existing segmentation methods, demonstrating effective generalization across diverse datasets while maintaining patient privacy through federal learning.

Article Synopsis
  • The study aimed to analyze serum lipid profiles in patients with localized osteosarcoma around the knee before and after they underwent neoadjuvant chemotherapy.
  • A cohort of 50 patients was evaluated, showing significant increases in several lipid markers, including total cholesterol and triglycerides, after treatment, indicating a change in lipid metabolism due to chemotherapy.
  • While pretreatment lipid levels did not predict histologic response to chemotherapy, increases in certain lipoproteins may suggest potential prognostic significance related to disease-free survival.

Background: To develop a convenient modality to predict axillary response to neoadjuvant chemotherapy (NAC) in breast cancer patients.

Materials And Methods: In this multi-center study, a total of 1019 breast cancer patients with biopsy-proven positive lymph node (LN) receiving NAC were randomly assigned to the training and validation groups at a ratio of 7:3. Clinicopathologic and ultrasound (US) characteristics of both primary tumors and LNs were used to develop corresponding prediction models, and a nomogram integrating clinicopathologic and US predictors was generated to predict the axillary response to NAC.

Objective: Ovarian cancer is the most deadly deadliest gynecological tumor in the female reproductive system. Therefore, the present study sought to determine the diagnostic performance of International Ovarian Tumor Analysis Simple Rules (IOTA SR), the Ovarian-Adnexal Reporting and Data System (O-RADS), and Cancer Antigen 125 (CA125) in discriminating benign and malignant ovarian tumors. The study also assessed whether a combination of the two ultrasound categories systems and CA125 can improve the diagnostic performance.

Purpose: Using antibodies to block the programmed cell death 1 (PD-1)/programmed cell death-ligand 1 (PD-L1) pathway as an immunotherapy has achieved great success in the clinical treatment of various types of carcinoma. However, the efficacy is limited because of tumor-mediated immune immunosuppression and evasion. This study demonstrated that inhibiting the PI3K pathway with (-)-4--(4----glucopyranosylcaffeoyl) quinic acid (QA), a new compound from endophytic fungus of , enhanced the therapeutic efficacy of anti-PD-L1 antibody against esophageal tumors.

Au/CeO was demonstrated to be a high efficiency catalyst for the conversion of 2-phenoxyacetophenol (PP-ol) employing O as an oxidant and methyl alcohol as the solvent without using an erosive strong base or acid. Mechanistic investigations, including emission quenching experiments, electron spin-resonance (ESR) and intermediate verification experiments, were carried out. The results verified that the superoxide anion activated by Au/CeO from molecular oxygen plays a vital role in the oxidation of lignin model compounds, and the cleavage of both the β-O-4 and C-C linkages was involved.

Ultrasound elastography has been introduced into clinical practice for a decade and arisen continuous increasing attention worldwide. Shear wave elastography (SWE) is a further extension of ultrasound elastography on the basis of strain elastography, providing a two-dimensional distribution map of tissue stiffness and quantitative measurement of the tissue stiffness in Young's modulus (kPa) and/or shear wave speed (m/s). The Society of Ultrasound in Medicine, Chinese Medical Association (CMA) has recently released a series of guidelines for the use of SWE, including the technique and principle of SWE, and use of SWE in liver fibrosis, breast, thyroid, and musculoskeletal system.

Monitoring the dynamic pH changes in vivo remains very essential to comprehend the function of pH in various physiological processes. In this study, we report a high-performance electrochemical pH microneedle based on an acupuncture needle (AN) for real-time monitoring of pH changes in a rat brain. The pH microneedle was prepared by a layer-to-layer assembly of molybdenum disulfide (MoS2) nanosheets and polyaniline (PAN), with an attempt to achieve a highly sensitive detection of hydrogen ions (H+).

To propose a risk stratification system for intermediate-risk thyroid nodules (TNs) according to American Association of Clinical Endocrinologists, American College of Endocrinology and Associazione Medici Endocrinologi Medical (AACE/ACE/AME) Guideline with ultrasound (US) features. 1000 patients with 1000 nodules (902 benign nodules and 98 malignant nodules) were included. All the nodules were confirmed with either fine needle aspiration (FNA) cytology and follow-up or histology results after surgery.

This work describes the adaptive use of a conventional stainless steel acupuncture needle as the electrode substrate for construction of a molybdenum disulfide (MoS) and platinum nanoparticles (PtNPs) layer-modified microneedle sensor for real-time monitoring of hydrogen peroxide (HO) release from living cells. To construct the nanocomposite-functionalized microneedle, the needle surface was first coated with a gold film by ion sputtering to enhance the conductivity. Subsequently, an electrochemical deposition method was successfully employed to deposit MoS nanosheet and Pt nanoparticles on the needle tip as the sensing interface.

The prognosis for patients with relapsed/metastatic osteosarcoma is poor and the optimal treatment strategy remains to be refined. Whilst gemcitabine plus docetaxel combination treatment has already been demonstrated to have certain promising results in the treatment of osteosarcoma, the use of pemetrexed, a multi-targeted antifolate, remains controversial. In the present study, a retrospective investigation was conducted to evaluate the toxicity and efficacy of the pemetrexed plus cisplatin combination in relapsed/metastatic osteosarcoma.

Insomnia is a common sleep disorder which is prevalent in women and the elderly. Current insomnia drugs mainly target the γ-aminobutyric acid (GABA) receptor, melatonin receptor, histamine receptor, orexin, and serotonin receptor. GABAA receptor modulators are ordinarily used to manage insomnia, but they are known to affect sleep maintenance, including residual effects, tolerance, and dependence.

Inhibition of vascular epithelial growth factor (VEGF) signaling pathways has proven to be an effective strategy for the treatment of several common solid tumors, but its role in the management of advanced gastric cancer (AGC) is yet to be defined. We performed a meta-analysis of randomized controlled trials (RCTs) to assess the efficacy and safety of anti-VEGF agents in the treatment of AGC. Several databases were searched, including PubMed, Embase, and Cochrane databases.
