SMYD3 drives cell cycle and epithelial-mesenchymal transition pathways through dual gene transcriptional repression and activation in HPV-negative head and neck cancer
AbstractHuman papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type in the world and is associated with an overall poor prognosis. The protein methyltransferase SET and MYND domain-containing 3 (SMYD3), which trimethylates H3K4, activates gene transcription and enhances several oncogenic pathways, including epithelial-mesenchymal transition and cell cycle related pathways, in various cancer types. It was also recently shown that SMYD3 is overexpressed in HPV-negative HNSCC, and represses the expression of type I IFN response genes, contributing to resistance to anti-PD-1 checkpoint blockade in this disease. In this study, we show that SMYD3 depletion using siRNA interference or CRISPR decreases cellular proliferation and clonal capacity, induces cell cycle arrest and decreases the invasive potential of HPV-negative HNSCC cell lines. Accordingly, xenografts of SMYD3 knockout tumors derived from a human HPV-negative HNSCC cell line grew significantly slower compared to control tumors in mice. Genome-wide mapping for SMYD3 and H3K4me3 in HPV-negative HNSCC cells using cleavage under targets and release using nuclease (CUT&RUN) assays identified direct downstream gene targets regulated by SMYD3, including cell cycle- and EMT-promoting genes. This study provides insights into the epigenetic role of SMYD3 as an oncogene in HPV-negative HNSCC and supports SMYD3 as a rational therapeutic target in HPV-negative HNSCC.
Polycystic ovary syndrome negatively affects sexual function and lower urinary tract symptoms in syrian women: a case-control study
Abstract Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder in women of reproductive age worldwide, and its related features like obesity, mental health issues and hyperandrogenism may contribute to inadequately investigated health problems such as sexual dysfunction (SD) and lower urinary tract symptoms (LUTS). Therefore, this study examined the impact of PCOS on sexual function (SF) and lower urinary tract in Syrian women by recruiting a total of 178 women of reproductive age, of whom 88 were diagnosed with PCOS according to the Rotterdam criteria and 90 without PCOS were considered as the control group. Female sexual function index (FSFI) and Bristol Female Lower Urinary Tract Symptom Questionnaire (BFLUTS) were used to assess SF and LUTS respectively. PCOS group had higher SD prevalence compared to control group (65.9% vs 48.9%, p = 0.016), and BMI showed an inverse correlation with the total FSFI score in PCOS group ( p = 0.027, r = -0.235). Furthermore, PCOS group exhibited significantly lower scores in orgasm and satisfaction subdomains. Additionally, PCOS patients had significantly higher total BFLUTS score compared to control group (median 8 vs 5, p = 0.025). Thus, PCOS may be related to SD and LUTS, highlighting the importance of evaluating SF and urinary symptoms in PCOS patients.

Soil fluoride enrichment process and the possible adaptation prevention principle in coal-burning fluorosis area in Southwest China
AbstractCoal-burning fluorosis prevails in southwest China and other provinces. Although clay used as binder of briquettes was proven to cause coal-burning fluorosis, its enrichment processes remain unknown. The soils and rocks on typical geological units were sampled and simulation experiments were performed to detect the forming process of high-fluoride clay. The surface and mineral soils, farmland soils and rocks have fluoride levels of 157.9–1076.76, 334.58–1419.28, 227.52–1303.11 and 46.05–964.11 mg/kg respectively. Fluoride levels of surface soils, mineral horizon soils and farmland soils are significantly positively correlated, while those between soils and rocks are not significantly correlated. The soils overlying carbonates have substantially higher fluoride levels than those overlying non-carbonates although the carbonates have extremely lower fluoride levels. The fluoride levels in acid insoluble substances are significantly positively correlated with soil fluoride levels. The acid insoluble substances in carbonates have obviously higher fluoride levels than those in non-carbonates. High Ca(Mg) levels in carbonates restrict fluorine leaching into the water and facilitate fluorine deposition in soils. Fluoride enriches in soils with numerous Ca(Mg)CO3 leaching during carbonate weathering, which is a new insight into the cause of high-fluoride clay. An exposure pathway of fluoride is forwarded. The best prevention principle and policy are proposed.

A latent diffusion approach to visual attribution in medical imaging
Abstract Visual attribution in medical imaging seeks to make evident the diagnostically-relevant components of a medical image, in contrast to the more common detection of diseased tissue deployed in standard machine vision pipelines (which are less straightforwardly interpretable/explainable to clinicians). We here present a novel generative visual attribution technique, one that leverages latent diffusion models in combination with domain-specific large language models, in order to generate normal counterparts of abnormal images. The discrepancy between the two hence gives rise to a mapping indicating the diagnostically-relevant image components. To achieve this, we deploy image priors in conjunction with appropriate conditioning mechanisms in order to control the image generative process, including natural language text prompts acquired from medical science and applied radiology. We perform experiments and quantitatively evaluate our results on the COVID-19 Radiography Database containing labelled chest X-rays with differing pathologies via the Frechet Inception Distance (FID), Structural Similarity (SSIM) and Multi Scale Structural Similarity Metric (MS-SSIM) metrics obtained between real and generated images. The resulting system also exhibits a range of latent capabilities including zero-shot localized disease induction, which are evaluated with real examples from the cheXpert dataset.

Investigations on the synthesis and characterization of silver-doped MoO3 thin films for photocatalytic applications
AbstractIn this study, we aimed to enhance the photocatalytic performance of molybdenum oxide (MoO3) thin films by doping with silver (Ag) via a spray pyrolysis technique. The primary objective for silver incorporation was intended to introduce additional energy levels into the band structure of MoO3, improving its efficiency. Structural, optical, and photocatalytic properties were analyzed using X-ray diffraction (XRD) and optical spectroscopy. XRD results confirmed an orthorhombic phase with a (040) preferential orientation for all samples. Optimal crystallinity was observed with 2% Ag doping, yielding an 84 nm crystallite size, while higher doping levels reduced crystallite size. Band gap energy narrowed from 3.07 eV (undoped) to 2.94 eV (2% Ag-doped), indicating electronic structure changes. Impedance spectroscopy revealed superior electrical properties at 4% Ag doping, enhancing charge transport. Photocatalytic performance, assessed via dye degradation, showed significant improvement with silver doping, the degradation rate peaking at 4% Ag. These results demonstrate that silver doping optimizes structural and electronic properties of MoO3 thin films, leading to enhanced photocatalytic activity.
