Obtaining clear images is of great help in determining the type and etiology of AIO, and doctors can quickly develop treatment plans to improve prognosis and efficacy.

Methods: The clinical data of patients with suspected AIO admitted to our hospital from May 2020 to May 2022 were retrospectively selected as the observation objects.

Natural Matrine-Integrated Pollen Delivery Systems for Allergic Contact Dermatitis Treatment.

Allergic contact dermatitis (ACD) is an inflammatory dermatitis with a high morbidity and recurrence rate. Scientific attention is focused on the development of safe and comfortable therapeutics of ACD. Herein, we propose a natural matrine-integrated pollen delivery system for the ACD treatment.

Lipid droplet efferocytosis attenuates proinflammatory signaling in macrophages via TREM2- and MS4A7-dependent mechanisms.

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by injury to steatotic hepatocytes that triggers the release of endogenous danger-associated molecular patterns. Recent work demonstrated that exposed lipid droplets (LDs) serve as a pathogenic signal that promotes monocyte infiltration and its maturation into triggering receptor expressed in myeloid cells 2 (TREM2) macrophages in MASH liver. Here we explore the role of LD exposure in modulating inflammatory signaling in macrophages.

Improvement of classical therapy in EGFR inhibitors-induced cutaneous adverse reaction by microneedle delivery and Astragalus polysaccharide.

EGFR (epidermal growth factor receptor) inhibitors, as the first-line drugs of targeted therapy, often cause additional distress for patients due to the induced cutaneous adverse reactions (EICAR), while classical therapies represented by topical minocycline and epidermal growth factor have limitations especially for exacerbating immune imbalance. Here, we used Astragalus polysaccharide (APS), which has modulatory effects on both the epidermis and the immune system, as an adjuvant drug to reduce EICAR and achieve immune balance. APS, combined with minocycline or epidermal growth factor, was delivered by dissolvable microneedles (MN), a novel drug delivery method that penetrates the stratum corneum to deliver the drug directly into the skin tissue.

Bioprinted Fibroblast Mediated Heterogeneous Tumor Microenvironment for Studying Tumor-Stroma Interaction and Drug Screening.

Cancer-associated fibroblasts (CAFs) are crucial stromal cells in the tumor microenvironment, affecting cancer growth, angiogenesis, and matrix remodeling. Developing an effective in vitro tumor model that accurately recapitulates the dynamic interplay between tumor and stromal cells remains a challenge. In this study, a 3D bioprinted fibroblast - mediated heterogeneous breast tumor model was created, with tumor cells and fibroblasts in a bionic matrix.

Gate-tunable photodetectors based on MoTe/MoSheterostructures anti-ambipolar transistors.

Anti-ambipolar transistors (AATs) are considered as a breakthrough technology in the field of electronics and optoelectronics, which is not only widely used in diverse logic circuits, but also crucial for the realization of high-performance photodetectors. The anti-ambipolar characteristics arising from the gate-tunable energy band structure can produce high-performance photodetection at different gate voltages. As a result, this places higher demands on the parametric driving range (Δ) and peak-to-valley ratio (PVR) of the AAT.

Suppression of Photoexcited Small Polarons-Mediated Energy Transfer to Boost Photoluminescence of Lanthanide-Titanium Nanoclusters.

Lanthanide (Ln)-titanium-based molecular nanoclusters (NCs) have attracted much attention due to their atomically precise total structure and promising optical behavior, while there is still minimal cognition of structure-dictated electron relaxation dynamics in such an NCs regime with unsatisfied photoluminescence quantum yield (PLQY, in general below 20%). Herein, the photoexcited small polarons (i.e.

Ginsenoside Rd alleviates early brain injury by inhibiting ferroptosis through cGAS/STING/DHODH pathway after subarachnoid hemorrhage.

Ferroptosis, a recently identified form of regulated cell death, is characterized by lipid peroxidation and iron accumulation, plays a critical role in early brain injury after subarachnoid hemorrhage. Ginsenoside Rd, an active compound isolated from ginseng, is known for its neuroprotective properties. However, its influence on SAH-induced ferroptosis remains unclear.

Manner implicatures in large language models.

In human speakers' daily conversations, what we do not say matters. We not only compute the literal semantics but also go beyond and draw inferences from what we could have said but chose not to. How well is this pragmatic reasoning process represented in pre-trained large language models (LLM)? In this study, we attempt to address this question through the lens of manner implicature, a pragmatic inference triggered by a violation of the Grice manner maxim.

SIRT3 differentially regulates lysine benzoylation from SIRT2 in mammalian cells.

Lysine benzoylation (Kbz), a new type of protein post-translational modification (PTM) we discovered, has garnered significant attention. While we initially identified SIRT2 as a debenzoylase in mammalian cells, recent findings suggest its exclusivity may be questioned. However, other debenzoylases in mammalian cells remain underexplored.

Liver-directed AAV gene therapy normalizes disease symptoms and provides cross-correction in a model of lysosomal acid lipase deficiency.

Lysosomal acid lipase deficiency (LAL-D) is caused by mutations in the LIPA gene, which encodes the lysosomal enzyme that hydrolyzes triglycerides and cholesteryl esters to free fatty acids and free cholesterol. The objective of this study was to develop a curative single-treatment therapy for LAL-D using adeno-associated virus (AAV). Treatment at both early (1-2 days) and late (8-week) timepoints with rscAAVrh74.

On the influence of discourse connectives on the predictions of humans and language models.

Psycholinguistic literature has consistently shown that humans rely on a rich and organized understanding of event knowledge to predict the forthcoming linguistic input during online sentence comprehension. We, the authors, expect sentences to maintain coherence with the preceding context, making congruent sentence sequences easier to process than incongruent ones. It is widely known that discourse relations between sentences (e.

Sirtuin 1/sirtuin 3 are robust lysine delactylases and sirtuin 1-mediated delactylation regulates glycolysis.

Lysine lactylation (Kla), an epigenetic mark triggered by lactate during glycolysis, including the Warburg effect, bridges metabolism and gene regulation. Enzymes such as p300 and HDAC1/3 have been pivotal in deciphering the regulatory dynamics of Kla, though questions about additional regulatory enzymes, their specific Kla substrates, and the underlying functional mechanisms persist. Here, we identify SIRT1 and SIRT3 as key "erasers" of Kla, shedding light on their selective regulation of both histone and non-histone proteins.

Comparative efficacy of intratympanic gentamicin and intratympanic corticosteroid in the treatment of Meniere's disease: a systematic review and meta-analysis.

Purpose: We aimed to evaluate the efficacy of gentamicin compared to corticosteroids for the treatment of Meniere's disease.

Methods: An extensive search was conducted in PubMed, Embase, and Web of Science until May 2024. For continuous outcomes, pooled effect estimates were determined by calculating the weighted mean difference (WMD), while for binary outcomes, the risk ratio (RR) was used, each accompanied by their respective 95% confidence intervals (CIs).

Strategy to optimize the broadband near-infrared emission based on Eu-doped sulfureted garnet phosphors toward emerging spectroscopy applications.

Eu-doped near-infrared (NIR) emitting phosphors, known for their high efficiency, broadband emission and spectral tunability, have gained much attention. However, achieving efficient NIR emission based on Eu remains a challenge due to the co-existence of Eu, especially in materials (i.e.

Enrichment characteristics of microplastics in Antarctic benthic and pelagic fish and krill near the Antarctic Peninsula.

Global microplastic pollution has garnered widespread attention from researchers both domestically and internationally. However, compared to other regions worldwide, little is known about microplastic pollution in the marine ecosystems of the Antarctic region. This study investigated the abundance and characteristics of microplastics (MPs) in the gills and intestines of 15 species of Antarctic fish and Antarctic krill (Euphausia superba).

Opioid-free anesthesia with esketamine-dexmedetomidine versus opioid-based anesthesia with propofol-remifentanil in shoulder arthroscopy: a randomized controlled trial.

Background: OFA (Opioid-free anesthesia) has the potential to reduce the occurrence of opioid-related adverse events and enhance postoperative recovery. Our research aimed to investigate whether OFA, combining esketamine and dexmedetomidine, could serve as an alternative protocol to traditional OBA (opioid-based anesthesia) in shoulder arthroscopy, particularly in terms of reducing PONV (postoperative nausea and vomiting).

Methods: A total of 60 patients treated with shoulder arthroscopy from September 2021 to September 2022 were recruited.

For treating knee osteoarthritis, physical therapy is highly regarded as a very effective treatment method.

Vaccarin Ameliorates Doxorubicin-Induced Cardiotoxicity via Inhibition of p38 MAPK Mediated Mitochondrial Dysfunction.

Doxorubicin is a frequently used chemotherapeutic agent for treating various malignancies. However, it leads to severe cardiotoxic side effects, such as heart failure, and elevates the risk of sudden cardiac death among cancer patients. While oxidative stress has been identified as the primary cause of doxorubicin-induced cardiotoxicity, therapeutic antioxidant approaches have yielded unsatisfactory outcomes.

BCAT1 alleviates early brain injury by inhibiting ferroptosis through PI3K/AKT/mTOR/GPX4 pathway after subarachnoid hemorrhage.

Regulation of the redox system by branched-chain amino acid transferase 1 (BCAT1) is of great significance in the occurrence and development of diseases, but the relationship between BCAT1 and subarachnoid hemorrhage (SAH) is still unknown. Ferroptosis, featured by iron-dependent lipid peroxidation accompanied by the depletion of glutathione peroxidase 4 (GPX4), has been implicated in the pathological process of early brain injury after subarachnoid hemorrhage. This study established SAH model by endovascular perforation and adding oxyhemoglobin (Hb) to HT22 cells and delved into the mechanism of BCAT1 in SAH-induced ferroptotic neuronal cell death.

Antiviral C-geranylated flavonoids from Artocarpus communis.

Ten C-geranylated flavonoids, along with three known analogues, were isolated from the leaves of Artocarpus communis. The chemical structures of these compounds were unambiguously determined via comprehensive spectroscopic analysis, single-crystal X-ray diffraction experiments, and quantum chemical electronic circular dichroism calculations. Structurally, artocarones A-I (1-9) represent a group of unusual, highly modified C-geranylated flavonoids, in which the geranyl chain is cyclised with the ortho-hydroxy group of flavonoids to form various heterocyclic scaffolds.
