    A practical approach to the difficult urethral catheterization for urology trainees

    Wyatt MacNevin1,*, Daniel T. Keefe1,2, Karen Milford1,2, Nicholas R. Paterson1

    Canadian Journal of Urology, Vol.32, No.1, pp. 5-13, 2025, DOI:10.32604/cju.2025.064697 - 20 March 2025

    Abstract Urethral catheterization is an important skill to develop as consultations for “difficult catheterization” are common in practice. Developing a broad approach to difficult urethral catheterization is crucial to improve trainee success rates. Strategies and techniques to improve catheterization success are often passed down and shared between trainees without formal documentation or dissemination of techniques. Herein, we present a framework for difficult urethral catheterization based on clinical history and patient examination, while also providing additional techniques and troubleshooting to overcome common challenges with urethral catheterization in adult and pediatric patients.

    Chaichawin Chavapradit1, Wonnop Visessanguan2, Suwan Panjanapongchai1, Anil Kumar Anal1,*

    Journal of Renewable Materials, Vol.13, No.3, pp. 553-582, 2025, DOI:10.32604/jrm.2025.058857 - 20 March 2025

    Abstract The growing population and industrialization have led to significant production in agro-industrial sectors, resulting in large amounts of agro-industrial residues often left untreated, posing potential environmental issues. Therefore, finding effective ways to utilize these bio-based residues is crucial. One promising approach is to use these low- or no-value agro-industrial wastes as raw materials for producing renewable biomaterials, including proteins and peptides. Research has extensively explored peptide extraction using plant and animal-based agro-industrial residue. Due to lower processing costs and beneficial bioactive properties, peptides derived from waste could replace synthetic peptides and those extracted from food More >

    Heni Radiani Arifin1,*, Yoan Christina Angelica1, Bambang Nurhadi1, Herlina Marta1, Rossy Choerun Nissa2

    Journal of Renewable Materials, Vol.13, No.3, pp. 617-635, 2025, DOI:10.32604/jrm.2025.057812 - 20 March 2025

    Abstract Bionanocomposite film is produced from renewable and biodegradable natural resources. Although elephant foot yam (EFY) starch (Amorphophallus paeoniifolius) is a promising polymer for bionanocomposite film, the native hydrophilic properties influence the overall performance characteristics. Incorporating virgin coconut oil (VCO) and monoglyceride as hydrophobic components can improve mechanical properties and reduce permeability while increasing the hydrophobicity of the composite. Therefore, this study aimed to determine the effect of adding VCO and monoglyceride on EFY starch-nanocrystalline film at 3 and 5 wt% concentrations. Experimental tests were conducted to evaluate the physical and mechanical properties, water vapor transmission rate… More > Graphic Abstract

    Journal of Renewable Materials, Vol.13, No.3, pp. 539-552, 2025, DOI:10.32604/jrm.2024.056813 - 20 March 2025

    Abstract Bio-based thermoplastic film from flax fiber and fatty acid (FA) was obtained using trifluoroacetic anhydride (TFAA) as an impelling agent. Different quantities of TFAA/FA, size of flax fiber, and fatty acids were applied to investigate chemical structure in relation to the mechanical properties. Decreasing the quantity of TFAA/FA by almost half from 1:4 to 1:2.5 (flax to TFAA/FA) only reduces by 22% the weight percent gain (WPG) and ester content and reducing flax fiber size slightly increases the WPG and ester content. All the treatments showed significant chemical structure modification, observed by FTIR and… More > Graphic Abstract

    Abstract Background: immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic urothelial carcinoma (mUC), significantly improving survival outcomes. However, a subset of patients do not respond to ICIs, prompting research into potential predictive factors. Commonly prescribed medications such as corticosteroids, proton-pump inhibitors (PPIs), antibiotics (Abs), antihypertensives, and analgesics may influence ICI effectiveness. Methods: we conducted a literature search on PubMed to investigate the impact of concomitant medications on the outcomes of patients with mUC, treated with ICIs. We selected the most relevant studies and performed a narrative review. Results: corticosteroids, PPIs and Abs have been associated More >

    Oncology Research, Vol.33, No.4, pp. 759-779, 2025, DOI:10.32604/or.2024.057019 - 19 March 2025

    Abstract Cancer remains one of the leading causes of death in the world, with more than 9 million deaths in 2022, a number that continues to rise. This highlights the urgent need for the development of new drugs, with enhanced antitumor capabilities and fewer side effects. Metal-based drugs have been used in clinical practice since the late 1970s, beginning with the introduction of cisplatin. Later, two additional platinum-based molecules, carboplatin, and oxaliplatin, were introduced, and all three continue to be widely used in the treatment of various cancers. However, despite their significant anticancer activity, the undesirable… More > Graphic Abstract

    Abstract Objectives: Glioblastoma (GB) is a grade IV glial tumor characterized by high malignancy and dismal prognosis, primarily due to high recurrence rates and therapeutic resistance. The epidermal growth factor receptor (EGFR), a receptor tyrosine kinase (RTK), regulates signaling pathways, including cell growth, proliferation, survival, migration, and cell death. Many cancers utilize immune checkpoints (ICs) to attenuate immune responses. CD73 is an enzyme that functions as an IC by hydrolyzing AMP to adenosine, suppressing immune cells in the tumor microenvironment. However, the role of CD73 in resistance to EGFR inhibitors is poorly understood. This study aims… More >
