    Canadian Journal of Urology, Vol.32, No.5, pp. 411-422, 2025, DOI:10.32604/cju.2025.066758 - 30 October 2025

    Abstract Objective: Urothelial carcinoma (UC) remains a prevalent malignancy with high recurrence and chemoresistance rates despite gemcitabine-cisplatin (GC) chemotherapy. The study aimed to identify clinical risk factors for chemoresistance in advanced UC patients and develop a predictive model. Method: A retrospective analysis was conducted on 375 UC patients who received postoperative GC chemotherapy between 2013 and 2024. Patients were categorized into chemotherapy-resistant (CR, n = 91) and non-chemotherapy resistant (NCR, n = 284) groups based on tumor progression. Clinical, pathological, and laboratory variables were compared using t-tests and chi-square tests. Kaplan-Meier assessed overall survival (OS), and binary More >

    Ventilation Velocity vs. Airborne Infection Risk: A Combined CFD and Field Study of CO2 and Viral Aerosols

    Chuhan Zhao1,*, Souad Morsli2, Laurent Caramelle3, Mohammed El Ganaoui3

    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.8, pp. 2001-2025, 2025, DOI:10.32604/fdmp.2025.068093 - 12 September 2025

    Abstract Carbon dioxide (CO2) is often monitored as a convenient yardstick for indoor air safety, yet its ability to stand in for pathogen-laden aerosols has never been settled. To probe the question, we reproduced an open-plan office at full scale (7.2 m 5.2 m 2.8 m) and introduced a breathing plume that carried 4% CO2, together with a polydisperse aerosol spanning 0.5–10 m (1320 particles s−1). Inlet air was supplied at 0.7, 1.4, and 2.1 m s−1, and the resulting fields were simulated with a Realisable – RANS model coupled to Lagrangian particle tracking. Nine strategically placed probes… More >

    A Time-Continuous Model for an Untreated HIV-Infection and a Novel Non-Standard Finite-Difference-Method for Its Discretization

    Benjamin Wacker1, Jan Christian Schlüter2,3,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.144, No.2, pp. 2191-2229, 2025, DOI:10.32604/cmes.2025.067397 - 31 August 2025

    Abstract In this work, we re-investigate a classical mathematical model of untreated HIV infection suggested by Kirschner and introduce a novel non-standard finite-difference method for its numerical solution. As our first contribution, we establish non-negativity, boundedness of some solution components, existence globally in time, and uniqueness on a time interval for an arbitrary for the time-continuous problem which extends known results of Kirschner’s model in the literature. As our second analytical result, we establish different equilibrium states and examine their stability properties in the time-continuous setting or discuss some numerical tools to evaluate this question.

    Phyton-International Journal of Experimental Botany, Vol.94, No.8, pp. 2479-2498, 2025, DOI:10.32604/phyton.2025.064850 - 29 August 2025

    Abstract Vascular wilt caused by Fusarium oxysporum f. sp. batatas (Fob) is a devastating disease threatening global sweet potato production. To elucidate Fob’s pathogenicity mechanisms and inform effective control strategies, we generated a green fluorescent protein (GFP)-tagged Fob strain to track infection dynamics in sweet potato susceptible cultivar Xinzhonghua and resistant cultivar Xiangshu75-55, respectively. Through cytological observation, we found in the susceptible Xinzhonghua, Fob predominantly colonized stem villi, injured root growth points, and directly invaded vascular bundles through stem wounds. Spore germination peaked at 2–3 h post-inoculation (hpi), followed by cyclical mycelial expansion and sporulation within vascular tissues… More >

    Exogenous and Endogenous Virus Infection and Pollutants Drive Neuronal Cell Senescence and Alzheimer’s Disease

    Federico Licastro*

    BIOCELL, Vol.49, No.6, pp. 981-989, 2025, DOI:10.32604/biocell.2025.062303 - 24 June 2025

    Abstract Alzheimer’s disease (AD) is a neurodegenerative disease causing the most frequent form of dementia in old age. AD etiology is still uncertain and deposition of abnormal proteins in the brain along with chronic neuroinflammation have been suggested as pathogenic mechanisms of neuronal death. Infections by exogenous neurotropic virus, endogenous retrovirus reactivation, infections by other microbes, and air pollutants may either induce neurodegeneration or activate brain inflammation. Up to 8% of the human genome has a retroviral origin. These ancient retroviruses, also called human endogenous retroviruses, are associated with a clinical history of several neurodegenerative diseases.… More >

    Abstract Introduction: Infections are the most feared complication of transrectal prostate biopsies, along with growing concerns of antibiotic resistance. Our institution transitioned to a transperineal approach without use of perioperative antibiotics or bowel preparations. We aimed to compare the safety outcomes associated with transperineal and transrectal prostate biopsy techniques. Materials and Methods: A retrospective analysis of patients who underwent transrectal and transperineal prostate biopsies at our institution from 2019–2022 was performed. Results: We identified 319 patients—174 transrectal and 145 transperineal. 8 patients who had transperineal biopsy (5.5%) received peri-operative antibiotics, compared to 100% with transrectal biopsy. 35.86%… More >

    Francesco Triggiano#, Giusy Diella#, Mara Lorusso, Paolo Veneziani*, Marilena D’Ambrosio, Daniela Nesta, Luigi Santacroce*

    BIOCELL, Vol.49, No.2, pp. 199-220, 2025, DOI:10.32604/biocell.2025.059322 - 28 February 2025

    Abstract The composition of the vaginal microbiota (VMB) influences the health of the female reproductive tract. Several studies have shown how the absence of lactobacilli causes an imbalance in the vaginal microbial community, favoring the development of infections. The present study aims to evaluate the relationship between the VMB and human papillomavirus (HPV) infection to clarify the role of the vaginal microbiota in the persistence and clearance of HPV. Many researchers have provided the scientific community with information on the composition of the microbiota and how it may also influence HPV infection and the development of… More >

    SEIR Mathematical Model for Influenza-Corona Co-Infection with Treatment and Hospitalization Compartments and Optimal Control Strategies

    Muhammad Imran1,*, Brett McKinney1, Azhar Iqbal Kashif Butt2

    CMES-Computer Modeling in Engineering & Sciences, Vol.142, No.2, pp. 1899-1931, 2025, DOI:10.32604/cmes.2024.059552 - 27 January 2025

    Abstract The co-infection of corona and influenza viruses has emerged as a significant threat to global public health due to their shared modes of transmission and overlapping clinical symptoms. This article presents a novel mathematical model that addresses the dynamics of this co-infection by extending the SEIR (Susceptible-Exposed-Infectious-Recovered) framework to incorporate treatment and hospitalization compartments. The population is divided into eight compartments, with infectious individuals further categorized into influenza infectious, corona infectious, and co-infection cases. The proposed mathematical model is constrained to adhere to fundamental epidemiological properties, such as non-negativity and boundedness within a feasible region.… More >

    Ghaliah Alhamzi1, Badr Saad T. Alkahtani2, Ravi Shanker Dubey3, Mati ur Rahman4,5,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.142, No.1, pp. 609-633, 2025, DOI:10.32604/cmes.2024.056604 - 17 December 2024

    Abstract This study directs the discussion of HIV disease with a novel kind of complex dynamical generalized and piecewise operator in the sense of classical and Atangana Baleanu (AB) derivatives having arbitrary order. The HIV infection model has a susceptible class, a recovered class, along with a case of infection divided into three sub-different levels or categories and the recovered class. The total time interval is converted into two, which are further investigated for ordinary and fractional order operators of the AB derivative, respectively. The proposed model is tested separately for unique solutions and existence on… More >
