    Textural, Rheological, Melting Properties, Particle Size Distribution, and Nmr Relaxometry of Cocoa Hazelnut Spread With Inulin-Stevia Addition as Sugar Replacer
    (John Wiley and Sons Inc, 2024) Berk,B.; Cosar,S.; Mazı,B.G.; Oztop,M.H.
    This study investigated the influence of substituting 60, 80, and 100% of the sugar in traditional cocoa hazelnut paste (control) formulation with inulin-stevia (90:10, w/w) mixture on textural and rheological characteristics, melting behavior, water activity (aw), particle size distribution (PSD), and color. Textural, rheological, melting properties, and color of samples were analyzed after 1, 2, and 3 months of storage at 11°C. Nuclear magnetic resonance (NMR) relaxometry experiments were also performed to understand the interaction of new ingredients with oil. Replacement of sugar with inulin-stevia gave darker color, reduced Casson yield stress, and changed the textural parameters and melting profile of the samples depending on the level but did not create a remarkable effect on PSD and Casson plastic viscosity. Increasing inulin-stevia content yielded lower aw and higher T2a values indicating decreased mobility of water. Complete removal of sugar caused low spreadability. The results showed that an 80% replacement level yielded a product with similar textural parameters and fat-melting mouth feeling compared to control sample. Cocoa hazelnut spreads prepared with inulin and stevia showed good textural stability during storage. © 2024 The Authors. Journal of Texture Studies published by Wiley Periodicals LLC.

    Cancer Stem Cells in Tumor Modeling: Challenges and Future Directions
    (John Wiley and Sons Inc, 2021) Dogan,E.; Kisim,A.; Bati-Ayaz,G.; Kubicek,G.J.; Pesen-Okvur,D.; Miri,A.K.
    Microfluidic tumors-on-chips models have revolutionized anticancer therapeutic research by creating an ideal microenvironment for cancer cells. The tumor microenvironment (TME) includes various cell types and cancer stem cells (CSCs), which are postulated to regulate the growth, invasion, and migratory behavior of tumor cells. In this review, the biological niches of the TME and cancer cell behavior focusing on the behavior of CSCs are summarized. Conventional cancer models such as 3D cultures and organoid models are reviewed. Opportunities for the incorporation of CSCs with tumors-on-chips are then discussed for creating tumor invasion models. Such models will represent a paradigm shift in the cancer community by allowing oncologists and clinicians to predict better which cancer patients will benefit from chemotherapy treatments. © 2021 The Authors.
