  • Data samples from the BESIII detector at the BEPCII collider were used to measure the Born cross sections for the e^{+}e^{-}→D^{0}D[over ¯]^{0} and D^{+}D^{-} processes with high precision.
  • Observations revealed clear peaks in the line shapes corresponding to various mass ranges, including G(3900), ψ(4040), ψ(4160), Y(4260), and ψ(4415).
  • These findings provide important experimental insights into the production of hadrons, particularly in the open-charm region.

China has made enormous strides to achieve high-quality development and biodiversity conservation, and the establishment of nature-protected areas is one of the essential initiatives. Caizi Lake involves a natural reserve and two national wetland parks, accommodating winter migratory waterfowl over the middle and lower Yangtze River basin in China. However, the water transfer from the Yangtze River to the Huai River (YR-HR water transfer) has modified the winter hydrological conditions of Caizi Lake, negatively affecting wintertime waterfowl habitats.

The fast biodegradation and poor biocompatibility of Mg alloys in physiological environments are still the main problems restricting their application in cardiovascular stents. In this study, the hydrogel coatings (SBMA-AAM) with different proportions of methacryloyl ethyl sulfobetaine (SBMA) and acrylamide (AAM) were built on the surface of AZ31B magnesium alloy through ultraviolet (UV) polymerization. The corrosion degradation behavior, hemocompatibility, and endothelial cell (EC) growth performance of the samples were studied in detail.

Viroporins are small, hydrophobic viral proteins that modify cellular membranes to form tiny pores for influx of ions and small molecules. Previously, viroporins were identified exclusively in vertebrate viruses. Recent studies have shown that both plant-infecting positive-sense single-stranded (+ss) and negative-sense single-stranded (-ss) RNA viruses also encode functional viroporins.

There is still controversial or limited evidence on whether sex differences exist in clinical characteristics, the risk of contrast-induced nephropathy (CIN), and other clinical outcomes of patients who received coronary angiography (CAG) and/or percutaneous coronary intervention (PCI). The aim of this study was to characterize the effect of sex on clinical characteristics and outcomes of patients undergoing CAG and/or PCI. A total of 3,340 consecutive patients undergoing CAG and/or PCI from May 2017 to December 2022 were assessed in this retrospective study.

Deep learning-based soft sensor modeling methods have been extensively studied and applied to industrial processes in the last decade. However, existing soft sensor models mainly focus on the current step prediction in real time and ignore the multistep prediction in advance. In actual industrial applications, compared to the current step prediction, it is more useful for on-site workers to predict some key performance indicators in advance.

Introduction: Hepatocellular carcinoma (HCC) accounts for 85% of liver cancer cases and is the third leading cause of cancer death. Regorafenib is a multi-target inhibitor that dramatically prolongs progression-free survival in HCC patients who have failed sorafenib therapy. However, one of the primary factors limiting regorafenib's clinical utilization is toxicity.

Article Synopsis
  • The study aimed to determine if bone marrow mesenchymal stem cells (BMMSCs) can help repair periodontal bone through a specific signaling pathway (PHD2/HIF-1) when faced with inflammation.
  • Researchers tested BMMSCs modified to silence the PHD2 gene in a lab environment simulating inflammation caused by bacteria, observing improved cell differentiation and bone health.
  • Results showed that silencing PHD2 boosted BMMSC function and increased vascular growth factors, suggesting that this genetic modification could be a promising method for treating bone loss due to inflammation.

Article Synopsis
  • The study focuses on the use of margetuximab plus chemotherapy as a treatment for HER2-positive metastatic breast cancer (MBC) in patients who have undergone several lines of prior therapy.
  • According to recent NCCN guidelines, this combination is recommended as a fourth-line or later therapy, especially for those who are hormone receptor-positive or negative.
  • The results from three heavily pretreated patients showed similar progression-free survival rates in real-world settings compared to earlier clinical trials, suggesting that margetuximab is a viable treatment option for certain patients.

Endo-periodontal lesions (EPLs) involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms, including unique anatomical and microbiological characteristics and multiple contributing factors. This etiological complexity leads to difficulties in determining patient prognosis, posing great challenges in clinical practice. Furthermore, EPL-affected teeth require multidisciplinary therapy, including periodontal therapy, endodontic therapy and others, but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.

Background: Brominated flame retardants (BFRs) are widely utilized to mitigate the flammability of various materials. Previous studies have revealed the impact of BFRs exposure on hormonal disruption and bone metabolism which are closely related to periodontitis. However, it remains unknown the potential relationship between BFRs and periodontitis.

Energy correlators that describe energy-weighted distances between two or three particles in a hadronic jet are measured using an event sample of sqrt[s]=13  TeV proton-proton collisions collected by the CMS experiment and corresponding to an integrated luminosity of 36.3  fb^{-1}. The measured distributions are consistent with the trends in the simulation that reveal two key features of the strong interaction: confinement and asymptotic freedom.

Objective To preliminarily explore the composition characteristics of gut microbiota in mice with type 2 diabetes mellitus (T2DM) and experimental periodontitis, and their correlation with serum IL-17 levels, aiming to provide new insights and evidence for related experimental studies. Methods A total of 42 SPF-grade C57BL/6J mice were randomly selected, with 24 used for T2DM modeling. Successfully modeled T2DM mice were divided into the T2DM group (ND group, n=8) and T2DM with experimental periodontitis group (PD group, n=8).

Article Synopsis
  • Sarcopenia is a condition related to aging that causes a decrease in muscle mass and strength, making early diagnosis important for effective treatment.
  • The study presents a new method for screening sarcopenia using a wearable device that monitors plantar pressure through a flexible sensing array made from barium titanate thin films, which can transmit data to a smartphone via Bluetooth.
  • By analyzing data from 51 participants, the study demonstrates that dynamic plantar pressure features can effectively distinguish between sarcopenic and non-sarcopenic individuals, achieving high accuracy in screening using machine learning techniques.

The cross beam of a mining linear vibrating screen is prone to cracking under long-term cyclic load. In order to accurately predict the fatigue life of the cracked cross beam, a coupled analysis method of vibration and crack propagation is proposed. A 2D dynamic model of the vibrating screen is established based on the finite element method, which is verified by the vibration test platform.

Alzheimer's disease (AD) is an intricate disorder involving amyloid deposits, neurofibrillary tangles, and chronic neuroinflammation. Though current Aβ-directed immunotherapies effectively eliminate amyloid plaques, their limited clinical benefits and notable safety concerns arise from overlooking two other neglected neurodegenerative features. Compelling evidence highlights synergistic cooperation between Aβ and tau, underscoring the imperative need to develop combinational therapies to target the diverse pathologies of AD.
