Numerous systemic diseases manifest with oral symptoms and signs. The molecular diagnosis of Alzheimer's disease (AD), the most prevalent neurodegenerative disease worldwide, currently relies on invasive or expensive methods, emphasizing the imperative for easily accessible biomarkers. In this study, we explored the expression patterns of key proteins implicated in AD pathophysiology within the taste buds of mice.

  • Smoking cessation can lead to weight gain, which may increase the risk of developing metabolic syndrome (MS), but results on this relationship have been inconsistent in previous studies.
  • A meta-analysis of 24 relevant studies found that ex-smokers had a higher risk of MS compared to active smokers, while the risk was not significantly different for male ex-smokers.
  • The analysis indicated that the risk of MS in men increased if the cessation period was 15 years or less but slightly decreased if the cessation period extended beyond 15 years.

Objective: To investigate temporal trends in mortality rates and underlying causes of death in persons with disabilities before and during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: Annual mortality rates and causes of death were analyzed using data covering the 2017-2022 period.

Results: The mortality rate among people with disabilities increased from 2017 to 2022; the rate was five times higher during COVID-19 in this population than in the general population.

Taste buds, the neuroepithelial organs responsible for the detection of gustatory stimuli in the oral cavity, arise from stem/progenitor cells among nearby basal keratinocytes. Using genetic lineage tracing, and were suggested as the specific markers for the stem/progenitor cells of taste buds, but recent evidence implied that taste buds may arise even in the absence of these markers. Thus, we wanted to verify the genetic lineage tracing of lingual - and -expressing cells.

Background: To investigate the prognosis of the remaining fetus in twin pregnancy after experiencing one fetal demise in the first trimester according to the location of the demised fetus.

Methods: This was a retrospective study of twin pregnancies with one fetal demise after the first trimester (14 weeks of gestation) delivered between September 2004 and September 2022. The study population was divided into two groups based on the location of the demised fetus as determined by the last recorded ultrasonography results: Group 1 included twin pregnancies where the presenting fetus was demised (n = 36) and Group 2 included twin pregnancies where the non-presenting fetus was demised (n = 44).

Discoidin domain receptor 1 (DDR1) kinase has emerged as a promising target for cancer therapy, and selective DDR1 inhibitors have shown promise as effective therapeutic candidates. Herein, we have identified the first coumarin-based selective DDR1 inhibitors via repurposing of a recent series of carbonic anhydrase inhibitors. Among these, ureidocoumarins , , and showed the best DDR1 inhibitory activities.

  • - The study focused on the ULTRACOL200 injectable filler, which uses polydioxanone (PDO) to promote collagen production and improve skin appearance, aiming to assess its effectiveness compared to other fillers.
  • - 31 participants aged 20 to 59 received injections of ULTRACOL200, and their skin texture and volume were measured at three different times: before treatment, 4 weeks after the first treatment, and 4 weeks after a second treatment.
  • - Results showed significant improvements in skin texture and reduced wrinkles, with participants reporting satisfaction after the treatments, highlighting the potential of PDO-based fillers for skin enhancement.

Background: Sphingolipids are signaling molecules and structural components of the axolemma and myelin sheath. Plasma sphingolipid levels may reflect disease status of neuromyelitis optica spectrum disorder (NMOSD). We aimed to examine plasma sphingolipids as disease severity biomarkers for NMOSD and compare their characteristics with those of serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP).

Hypopharyngeal squamous cell carcinoma (HSCC) is a relatively rare form of head and neck cancer that is notorious for its poor prognosis and low overall survival rate. This highlights the need for new therapeutic options for this malignancy. The objective of the present study was to examine the ability of caffeic acid phenethyl ester (CAPE), which is an active compound found in propolis, to combat HSCC tumor growth.

Genipin, a natural compound derived from the fruit of Gardenia jasminoides Ellis, was reported to have activity against various cancer types. In this study, we determined the underlying mechanism for genipin-induced cell death in human oral squamous cell carcinoma (OSCC). The growth-inhibitory effects of genipin in human OSCC cells was examined by the Cell Counting Kit-8 and soft agar assays.

Purpose: Neuropilin-2 (NRP2) is a multifunctional single-pass transmembrane receptor that binds to two disparate ligands, namely, vascular endothelial growth factors (VEGFs) and semaphorins (SEMAs). It is reportedly involved in neuronal and vascular development. In this study, we uncovered the exact functional role of NRP2 and its molecular mechanism during aggressive behaviors and lymph node (LN) metastasis in human head and neck cancer (HNC) and identified algal methanol extract as a potential novel NRP2 inhibitor.

The design of kinase inhibitors targeting the oncogenic kinase BCR-ABL constitutes a promising paradigm for treating chronic myeloid leukaemia (CML). Nevertheless, the efficacy of imatinib, the first FDA-approved targeted therapy for CML, is curbed by the emergence of resistance. Herein, we report the identification of the 2-methoxyphenyl ureidobenzothiazole as a potent pan-BCR-ABL inhibitor against imatinib-resistant mutants, particularly T315I.
