Propolis mouthwashes efficacy in managing gingivitis and periodontitis: a systematic review of the latest findings.
BDJ Open

Department of Orthodontics, Institute of Dentistry, Medical Faculty, Jagiellonian University, Kraków, Poland.
Background And Objectives: Gingivitis and periodontitis are common periodontal diseases that can significantly harm overall oral health, affecting the teeth and their supporting tissues, along with the surrounding anatomical structures, and if left untreated, leading to the total destruction of the alveolar bone and the connective tissues, tooth loss, and other more serious systemic health issues. Numerous studies have shown that propolis can help reduce gum inflammation, inhibit the growth of pathogenic bacteria, and promote tissue regeneration, but with varying degrees of success reported. For this reason, this comprehensive systematic review aims at finding out the truth concerning the efficacy of propolis mouthwashes in treating gingivitis and periodontitis, as its main objective.

While there are many public concerns about the impact of AI on truth and knowledge, especially when it comes to the widespread use of LLMs, there is not much systematic philosophical analysis of these problems and their political implications. This paper aims to assist this effort by providing an overview of some truth-related risks in which LLMs may play a role, including risks concerning hallucination and misinformation, epistemic agency and epistemic bubbles, bullshit and relativism, and epistemic anachronism and epistemic incest, and by offering arguments for why these problems are not only epistemic issues but also raise problems for democracy since they undermine its epistemic basis- especially if we assume democracy theories that go beyond minimalist views. I end with a short reflection on what can be done about these political-epistemic risks, pointing to education as one of the sites for change.

Existing within hierarchical kinship networks, requiring patronage of gurus, hijras, a 'third' gender community, undergo mandatory apprenticeship to a commune life through a discipleship-lineage system where castration is seen as a necessary truth and final rite of passage to achieve a virtuous hijra identity. This article examines the subjectivities of hijras from working-class backgrounds and narrows its focus to analyse how individual hijras develop an understanding of themselves from their occupied subject positions in the larger hijra community shaped by internal hijra cultural traditions (parampara) manifested through rituals of harm. Based on long-term ethnographic fieldwork of 10 years in New Delhi and its neighbouring states, this article discusses the genealogies of wound cultures through castration in the hijra community acquired through their experiential and vernacular knowledge systems of self-flagellation as a practice of ethical self-making for their sacred rebirth in a nirvana (a state of freedom from all suffering) body.

The purpose of this study was to develop a robust deep learning approach trained with a small in-vivo MRI dataset for multi-label segmentation of all eight carpal bones for therapy planning and wrist dynamic analysis. Approach: A small dataset of 15 3.0-T MRI scans from five health subjects was employed within this study.

Background: Dosimetric commissioning and quality assurance (QA) for linear accelerators (LINACs) present a significant challenge for clinical physicists due to the high measurement workload and stringent precision standards. This challenge is exacerbated for radiosurgery LINACs because of increased measurement uncertainty and more demanding setup accuracy for small-field beams. Optimizing physicists' effort during beam measurements while ensuring the quality of the measured data is crucial for clinical efficiency and patient safety.
