The fundamental frequency (fo) is pivotal for quantifying vocal-fold characteristics. However, the accuracy of fo estimation in hoarse voices is notably low, and no definitive algorithm for fo estimation has been previously established. In this study, we introduce an algorithm named, "Spectral-based fo Estimator Emphasized by Domination and Sequence (SFEEDS)," which enhances the spectrum method and conducted comparative analyses with conventional estimation methods.

DCBLD1 Modulates Angiogenesis by Regulation of the VEGFR-2 Endocytosis in Endothelial Cells.

Arterioscler Thromb Vasc Biol

December 2024

Department of Biochemistry and Molecular Biology, School of Basic Medicine, Hebei Medical University, Shijiazhuang, China. (Q.F., L.G., C.Y., X.L., Y.L., C.L., W.Z., Y.Z., W.Y., Y.M., R.W., L.L., Y.P., H.W., M.H., L.N.).

Background: Unwanted angiogenesis is involved in the progression of various malignant tumors and cardiovascular diseases, and the factors that regulate angiogenesis are potential therapeutic targets. We tested the hypothesis that DCBLD1 (discoidin, CUB, and LCCL domain-containing protein 1) is a coreceptor of VEGFR-2 (vascular endothelial growth factor receptor-2) and modulates angiogenesis in endothelial cells.

Methods: A carotid artery ligation model and retinal angiogenesis assay were used to study angiogenesis using globe knockout or endothelial cell-specific conditional knockout mice in vivo.

Background: Biweekly irinotecan plus cisplatin combination therapy (BIRIP) and irinotecan monotherapy (IRI) are both expectable second-line chemotherapy (SLC) options for treating advanced gastric cancer (AGC). Although many patients receiving SLC have undergone gastrectomy, the impact of gastrectomy on SLC remains unclear, and the impact of gastrectomy may vary from regimen to regimen.

Patients And Methods: A total of 290 eligible patients registered in two randomized phase III trials evaluating BIRIP (IRI, 60 mg/m; CDDP, 30 mg/m, q2w) or IRI (150 mg/m, q2w) for patients with AGC was classified into the prior gastrectomy subgroup (PGG) or the no gastrectomy subgroup (NGG).

Article Synopsis
  • Oral frailty (OF) is a type of frailty that has connections to psychosocial factors like laughter and social interaction, which can enhance longevity by lowering stress and promoting physical activity.
  • A study conducted in Fukushima from 2020 to 2021 surveyed 916 residents aged 60-79 to investigate the impact of laughter and social communication on the risk of developing OF, revealing a prevalence of 41.5%.
  • The analysis found that engaging in daily laughter and having no depressive symptoms significantly reduced the risk of OF, suggesting that promoting these factors could improve health outcomes for older adults.

Mechanistic Insights into the Effect of Sodium Iodide on Copper-Mediated Iododeboronation.

Chemistry

December 2024

Laboratory of Analytical and Bioinorganic Chemistry, Division of Analytical and Physical Sciences, Kyoto Pharmaceutical University, 5 Nakauchi-cho, Misasagi, Yamashina-ku, Kyoto, 607-8414, Japan.

The copper-catalyzed Chan-Evans-Lam (CEL) coupling reaction advances carbon-heteroatom cross-coupling and has facilitated the development of radiohalogenation methodologies in radiochemistry. This study investigated the mechanisms and side reactions of CEL iodination under conditions relevant to radiosynthesis and typical organic synthesis, focusing on the effects of sodium iodide. The concentrations of copper and iodide, as well as the copper-to-iodide ratio, were identified as significant factors for successful copper-mediated CEL iodination, influencing the reaction mechanisms and side reactions.

Article Synopsis
  • Researchers conducted a study to explore the connection between thyroid autoantibodies (Tabs) and the clinical profiles of young patients (ages 3-29) with thyroid nodules, using data from 3,018 participants in the Fukushima Health Management Survey.
  • The study discovered that Tabs were found in 13.9% of participants, with higher rates in females, those with diffuse goiter, and those diagnosed with papillary thyroid carcinoma.
  • Findings indicate that Tab positivity is linked to larger thyroid sizes, the presence of diffuse goiter and papillary thyroid carcinoma, and high TSH levels, suggesting that testing for Tabs could enhance assessment methods for thyroid function and cancer detection in younger patients with nodules.

Article Synopsis
  • - The study analyzed thyroid cancer detection in children and adolescents in Fukushima after the 2011 nuclear disaster, involving over 253,000 participants with varying levels of radiation exposure.
  • - Utilizing Poisson regression, the research assessed the relationship between external radiation exposure and thyroid cancer, concluding that there was no significant association even at low radiation doses.
  • - The findings indicated that over 99.9% of participants experienced radiation exposure below 5 mSv, with an average follow-up period of 3.7 years, and thus, low radiation exposure was unlikely to increase thyroid cancer risk.
