In this study, polysulfone/polyvinylpyrrolidone (PSf/PVP, 20 wt%/5 wt%)-based ultrafiltration (UF) membranes reinforced with different ratios (0.5 and 1 wt%) of cellulose nanocrystals (CNCs) and cellulose nanofibres (CNFs) were prepared by the phase inversion method. The effect of CNC, CNF, and CNC-CNF reinforcement on the morphology, roughness, crystallinity, porosity, average pore size, mechanical properties, and filtration performance of PSf/PVP-based membrane was investigated.

: The key components of the blood-brain barrier (BBB) are endothelial cells, pericytes, astrocytes, and the capillary basement membrane. The BBB serves as the main barrier for drug delivery to the brain and is the most restrictive endothelial barrier in the body. Nearly all large therapeutic molecules and over 90% of small-molecule drugs cannot cross the BBB.

Magnetic and Biomedical Properties of Iron Nanoparticles Synthesized Using Extract.

Materials (Basel)

December 2024

Biomedical Engineering Department, Faculty of Engineering and Architecture, Istanbul Yeni Yüzyıl University, Istanbul 34010, Türkiye.

Magnetic nanoparticles have attracted significant attention in nanoscience and nanotechnology due to their unique physicochemical properties. These properties enable their great potential in various biomedical applications, such as hyperthermia, drug delivery, tissue engineering, theranostics, and lab-on-a-chip technologies. Physical and chemical methods are conventionally used for the synthesis of nanoparticles; however, due to several limitations of these methods, research focus has recently shifted towards developing clean and eco-friendly synthesis protocols while maintaining their desirable chemical and physical properties.

Bee products are an important source of nutrients and bioactive phytochemicals. This study aimed to determine the chemical composition (proximate composition, general phytochemical composition, sugar, and phenolic profiles) of four different products (honey, bee pollen, bee bread, and propolis), obtained from the same apiary, as well as to assess their biological activity through antioxidant and enzyme inhibition assays (α-amylase, α-glucosidase, lipase, AchE, neuraminidase, angiotensin-converting enzyme, urease, trypsin, tyrosinase, carbonic anhydrase, thioredoxin reductase, adenosine deaminase). Clear differences were observed among the samples in terms of both chemical composition and biological activity.

Autoinflammatory Bone Diseases.

Balkan Med J

January 2025

Department of Pediatric Rheumatology, İstanbul University-Cerrahpaşa, Cerrahpaşa Faculty of Medicine, İstanbul, Türkiye.

Autoinflammatory bone diseases (AIBDs) constitute a recently identified subset of autoinflammatory diseases. These conditions are characterized by an exaggerated inflammatory response in the bones without any apparent etiology. Inflammatory bone lesions associated with AIBDs exhibit chronic inflammation, are typically culture-negative, and do not exhibit discernible microorganisms on histopathological examination.

Background: Morphological growth naturally progresses with age; however, the rate of growth varies across different parts of an organism, with certain structures developing more rapidly than others. This study aimed to analyze and compare the skull development of red foxes (Vulpes vulpes) during two specific developmental stages: the 3rd and 6th months, which represent distinct growth phases in their early ontogeny.

Methods: In this study, we aimed to analyze and compare skull development in red foxes (Vulpes vulpes) during two specific post-natal time points: the 3rd and 6th months.

This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

Article Synopsis
  • The study aimed to enhance early diagnosis of candidemia in ICU patients by identifying risk factors and developing a new scoring system, known as the Cerrahpaşa score.
  • A retrospective analysis of 100 ICU patients revealed key risk factors such as sepsis and prolonged antibiotic use, while a prospective evaluation of 75 patients established a cutoff score of ≥4 points as indicative of increased candidemia risk.
  • The research concluded that the Cerrahpaşa score, combined with a real-time PCR assay, could improve the early detection and management of candidemia in critically ill patients.
