Invasive inflammatory fibroid polyp of the stomach: A case report and literature review.

Rationale: Inflammatory fibrous polyp (IFP) is a distinct fibroblastic neoplasm with a predilection for the stomach and ileum. It usually presents prominent inflammatory infiltration, particularly eosinophils, and has been widely considered benign tumors without malignant biological behaviors. However, rare invasive cases have been reported.

Hepatic epithelioid hemangioendothelioma with rearrangement: a case report and literature review.

Epithelioid hemangioendothelioma (EHE) is a rare low-grade malignant tumor of vascular origin. It may be confusing as its manifestations of multifocal lesions on imaging and epithelial histomorphology in pathology. EHE is easy to be mistaken for a metastatic tumor by radiologists and clinicians.

Weak monsoon signals detected in growth chronologies of lake fish on the Qinghai-Tibetan Plateau.

Understanding the variation in fish growth responses to climate change across regions is essential for predicting fish population dynamics and relevant ecological consequences on a large scale. Despite the demonstrated sensitivity of fish growth responses to climate change on the Qinghai-Tibetan Plateau (QTP), the geographical variations in these responses remain unclear. This study analyzed the growth responses of schizothoracine fish to environmental variables in four geographically distinct QTP lakes (Qinghai Lake, Yamdrok Lake, Pangong Tso, and Co Nag) using otolith biochronologies and hierarchical mixed-effects modeling and quantified the relative contributions of intrinsic and extrinsic factors to fish growth variations.

Advanced diffusion-weighted imaging-derived quantitative parameters as biomarkers of fibrosarcoma-cell proliferation in nude mice: A study based on precise imaging-pathology correlation.

Purpose: To determine whether quantitative parameters derived using diffusion kurtosis imaging (DKI) and intravoxel incoherent motion (IVIM) imaging reflect pathological changes in fibrosarcoma.

Methods: Thirty nude mouse models of fibrosarcoma underwent T1/T2-weighted imaging, DKI, and IVIM imaging on a 3.0-T scanner.

Response of Plant Leaf Traits to Environmental Factors in Climax Communities at Varying Latitudes in Karst Regions.

Exploring the changes in plant functional traits and their relationship with the environment in karst climax communities across different latitudes can enhance our understanding of how these communities respond to environmental gradients. In this study, we focus on climax karst climax plant communities in Guizhou Province, China. We selected three sample sites located at varying latitudes and analyzed the variations in functional traits of the plant communities at these latitudes.

Correlation between METTL3 overexpression and F-FDG uptake in patients with soft tissue sarcoma.

Background: N6-methyladenosine (m6A) methylation plays a key role in tumor progression. However, the significance of methyltransferase-like 3 (METTL3) in biological processes of soft tissue sarcoma (STS) patients, and the relationship between METTL3 and STS are unclear.

Methods: The expression of METTL3 in STS and its relationship with patient prognosis were determined from database analyses.

Pathological-microenvironment responsive injectable GelMA hydrogel with visualized biodegradation for pressure-assisted treatment of hypertrophic scars.

Intralesional injection of 5-fluorouracil for the clinical treatment of hypertrophic scars (HS) remains challenging due to its short half-life, as well as the absence of evidence-based dosage and frequency injection guidelines. Herein, we developed a matrix metalloproteinases (MMPs)/reactive oxygen species (ROS)-responsive injectable prodrug hydrogel (GFP) that exhibits sustained drug release and fluorescence imaging capability, aiming to facilitate the optimization of injection dosage and frequency in HS treatment. The GFP hydrogel comprises gelatin methacryloyl and pendant methacryloyl-decorated tetrapeptide (PPPK) with 5-fluorouracil acetic acid/rhodamine B at the N-terminus.

Naphthalene Hydrodearomatization via Controllable Photocatalytic Hydroboration.

The photocatalytic dearomative 1,4-hydroboration of naphthalenes with an N-heterocyclic carbene borane (NHC-BH) complex was reported herein with controllable regioselectivity and chemoselectivity. This protocol yielded a wide range of naphthalene derivatives bearing various functional groups, notably bioactive compounds. Hydroboration occurred through the cooperation of photoredox and hydrogen atom transfer via boryl radical addition to naphthalene and further selective protonation.

Association Between Melanoma Metastasis and Metabolic Syndrome: A Cross-Sectional Study in a Chinese Population.

Metabolic syndrome (MetS) remains a significant global public health concern. However, the relationship between MetS, its individual components and melanoma metastasis remains unexplored. We analysed the clinical data of 258 Chinese melanoma patients who had not undergo systemic therapy.

Ultraweak light-modulated heterostructure with bidirectional photoresponse for static and dynamic image perception.

The human visual system's adaptability to varying brightness levels has inspired the development of optoelectronic neuromorphic devices. However, achieving bidirectional photoresponse, essential for mimicking these functions, often requires high operation voltages or high light intensities. Here, we propose a bidirectional ZnO/CsPbBr heterostructure based neuromorphic image sensor array (10 × 10 pixels) capable of ultraweak light stimulation.

MerTK macrophages promote melanoma progression and immunotherapy resistance through AhR-ALKAL1 activation.

Despite our increasing understanding of macrophage heterogeneity, drivers of macrophage phenotypic and functional polarization in the microenvironment are not fully elucidated. Here, our single-cell RNA sequencing data identify a subpopulation of macrophages expressing high levels of the phagocytic receptor MER proto-oncogene tyrosine kinase (MerTK macrophages), which is closely associated with melanoma progression and immunotherapy resistance. Adoptive transfer of the MerTK macrophages into recipient mice notably accelerated tumor growth regardless of macrophage depletion.

Otolith reliability is context-dependent for estimating warming and CO acidification impacts on fish growth.

Otoliths are frequently used as proxies to examine the impacts of climate change on fish growth in marine and freshwater ecosystems worldwide. However, the large sensitivity differences in otolith growth responses to typical changing environmental factors (i.e.

The prognostic implications of cuproptosis-related gene signature and the potential of PPIC as a promising biomarker in cutaneous melanoma.

Cutaneous melanoma is the most lethal of all skin tumors. Recently, cuproptosis, a novel form of cell death linked to oxidative phosphorylation, has emerged as an important factor. However, the precise role of cuproptosis in melanoma remains unclear.

TSC1 splicing mutation in renal angiomyolipoma with epithelial cysts without fat: A very rare case report and literature review.

Renal angiomyolipoma is a benign mesenchymal tumor that can be divided into classical and other subtypes. Angiomyolipoma with epithelial cysts (AMLEC) is an extremely rare non classical subtype. AMLEC without fat component is even rarer.

Air Pollution and Influenza: A Systematic Review and Meta-Analysis.

Background: Influenza is the first infectious disease that implements global monitoring and is one of the major public health issues in the world. Air pollutants have become an important global public health issue, in recent years, and much epidemiological and clinical evidence has shown that air pollutants are associated with respiratory diseases.
