Rising as a revolutionary tool in biomedical research, single-cell RNA sequencing (scRNA-seq) offers a hitherto unheard-of molecular portrait of cellular diversity. Examining gene expression in individual cells helps us to reconsider unusual cell forms, disease processes, and treatment strategies

Introduction: Pneumonia remains a leading cause of morbidity and mortality in children under five in many low- and middle-income countries. Maternal knowledge and practices play a crucial role in early detection and management. Objective: This study aimed to enhance evidence-based practices for pneumonia prevention in children. Method: A cross-sectional study was conducted with 300 mothers of children under five receiving pneumonia treatment at the National Children’s Hospital in Hanoi, Vietnam. Data were collected through a str...uctured interview questionnaire. Results: 83% of mothers demonstrated comprehensive knowledge of pneumonia’s clinical definition; 90.7% correctly identified its primary causes; 82.7% recognized cough as a key symptom, and 87.7% understood potential complications; 98% reported appropriate responses to early pneumonia signs, with 93% adhering to correct symptomatic management. However, knowledge gaps persisted: only 71.7% identified pneumonia risk factors, 48.7% recognized chest indrawing as a critical symptom, and 50% understood supportive measures for cough management. Conclusion: While the study highlights strengths in maternal knowledge and clinical practices, critical gaps remain, particularly in symptom recognition and risk factor awareness. Strengthening maternal education, particularly among socioeconomically disadvantaged groups, and improving pediatric healthcare access may reduce pneumonia-related morbidity and mortality.Read more

Numerous studies indicate that periodontal diseases affect a large portion of the adult population, and gum disease is a primary cause of losing teeth in the future. Periodontal diseases are a global health concern. Periodontal diseases are the most common and serious oral illnesses, affecting not only the gums but also the tissue and bone that support the teeth. It begins as gingivitis, a slight swelling of the gums resulting from the buildup of bacterial plaque. If not treated appropriately, it may advance to periodontitis, where the inflamma...tion and infection spread deeper, causing damage to the tissue and bone. The scientific data that deals with stress is vast; it covers different theories of the influence of stress, the consequences of stress on the body and the brain, and the other contributors of stress. The scientific data contains heterogeneous findings about stress's causes, nature, and subsequent effects. Aim: Since stress is a prevalent problem in modern life, the present work aims to estimate the association between stress and periodontal diseases, investigating the central relations highlighted in the scientific data.Methods: The search comprised electronic databases: MEDLINE (PubMed), and Google Scholar, open access journals published by Elsevier. The keywords for the search were "stress," "periodontal diseases," "cortisol," and "saliva" in different combinations. The search considered works published from 2014 until December 2024. The procedure is shown in the PRISMA flowchart.Conclusion: This review highlights the links between physiological stress, the stress hormone cortisol, and periodontal diseases, emphasizing the importance of considering stress as a risk factor in oral health. Understanding these relationships can help clarify discrepancies in treatment effectiveness and inform future healthcare practices.Read more

Multicenter molecular integrals over Dirac wave functions can be derived by using the Gaussian-transform for the Dirac wave function, which was derived by the author, for several fundamental properties; i.e., the overlap integral, the kinetic energy one, the nuclear attraction one for the point-like nucleus and for the finite one, and the electron-repulsion integral.

The analytical study examines the isothermal, unsteady flows of viscous incompressible fluids in a planar channel, when viscosity depends linearly on pressure, and a constant magnetic field is present. Exact expressions are derived for the dimensionless initial velocity field, the corresponding non-zero shear stress, and the problem is fully solved. To illustrate and highlight certain fluid behavior characteristics, modified Stokes’ problems are analyzed, and analytical expressions for the corresponding initial velocities are provided. Fo...r validation, the steady components are presented in two distinct forms, with their equivalence confirmed through graphical comparison. The effect of the magnetic field on the fluid behavior is explored and discussed visually. The results show that the fluid flows more slowly, and the steady-state is reached sooner when a magnetic field is applied.2010 Mathematics Subject Classification: 76A05.Read more
