    Development of Microfibrillated Cellulose-Based Films From Globe Artichokes (cynara Scolymus)
    (Elsevier, 2023) Erguner, Merve (Samli); Harsa, Hayriye Sebnem; Ergüner, Merve
    This research developed biodegradable packaging materials for fresh-cut artichokes using the waste of globe artichokes. The extraction of film-forming materials (cellulose, hemicellulose, lignin, and wax fractions) was done with a mild alkaline extraction method. An environmentally friendly mechanical grinding method (Masuko Supermasscolloider) was chosen to produce cellulose microfibrils having 50-200 mu m length and 10-30 mu m width. The presence of micro fibrillated cellulose in films hindered the heat sealing ability, so using microfibrillated cellulose and Carboxymethyl cellulose together in films (with glycerol, stearic acid, and wax incorporation) exhibited better performance. Micro fibrillated cellulose and Carboxymethyl cellulose-based films have good elasticity (16 % strain), tensile strength (0.85 kg/mm), and seal ability (at 170-220 degrees C). Scanning Electron Microscope analyses showed films with smooth surfaces and dense structures (from the cross-sectional area).

    Comparison of Apical and Basolateral Cu Treatment for Iron-Related Gene Regulation During Deferoxamine Induced Iron Deficiency
    (BioMed Central Ltd., 2022) Evcan, Ezgi; Güleç, Şükrü
    Background: Intestinal copper transporter (Atp7a) mutant-brindled mice with systemic Cu deficiency had elevated Cu levels in enterocyte cells without any perturbation of iron-regulating genes, suggesting that blood Cu level might be important for intestinal iron homeostasis during iron deficiency (ID). We hypothesized that the blood Cu level and polarization (apical and basolateral) of enterocyte cells might be important regulators for the compensatory response on the regulation of genes in enterocyte cells during iron deficiency. Methods: We grew Caco-2 cells on a bicameral cell culture plate to mimic the human intestine system and on a regular tissue culture plate. Iron deficiency was induced by deferoxamine (DFO). The cells were treated with Cu and Cu with Fe following mRNA expressions of DMT1, FPN, TFR, and ANKRD37 were analyzed. Results: Our main finding was that basolateral treatment of Cu significantly reduced mRNA expressions of iron-regulated genes, including DMT1, FPN, TFR, and ANKRD37, compared to DFO-treated and DFO with apical Cu-treated groups in both bicameral and regular tissue culture plates. Conclusions: Cu level in the basolateral side of Caco-2 cells significantly influenced the intracellular gene regulation in DFO-induced iron-deficient condition, and polarization of the cells might be important factor gene regulation in enterocyte cells.

    Aso Visual Abstract: Intervention for Hepatic and Pulmonary Metastases in Breast Cancer Patients-Prospective, Multi-Institutional Registry Study: Imet; Protocol Mf 14-02
    (Springer, 2022) Soran, Atilla; Özbaş, Serdar; Özçınar, Beyza; Işık, Arda; Doğan, L.; Şenol, Kazım; Dağ, Ahmet; Karanlık, Hasan; Aytaç, Özgür; Karadeniz Çakmak, Güldeniz; Dalcı, Kubilay; Doğan, Mutlu; Sezer, Atakan Y.; Gökgöz, Şehsuvar; Özyar, Enis; Sezgin, Efe
    The aim of our prospective, multicenter registry study was to investigate the importance of interventions for operable lung and/or liver metastasis for breast cancer (BC) survival (https://doi.org/10.1245/s10434-022-12239-z). The results reveal that surgical resection or ablative interventions may contribute to survival in patients with BC with limited number and operable metachronous hepatic/pulmonary metastases. Ultimately, randomized studies will determine whether intervention on lung and liver metastatic sites should be performed. In the meantime, such interventions can be considered on select patients.

    Intervention To Hepatic and Pulmonary Metastases in Breast Cancer Patients: Prospective, Multi-Institutional Registry Study-Imet; Protocol Mf 14-02
    (Springer, 2022) Soran, Atilla; Özbaş, Serdar; Özçınar, Beyza; Işık, Arda; Doğan, Lütfi; Şenol, Kazım; Dağ, Ahmet; Karanlık, Hasan; Aytaç, Özgür; Karadeniz Çakmak, Güldeniz; Dalcı, Kubilay; Doğan, Mutlu; Sezer, Atakan Y.; Gökgöz, Şehsuvar; Özyar, Enis; Sezgin, Efe
    Background/Objective: One‐fourth of early‐stage breast cancer (BC) becomes metastatic at follow‐up. Limited metastases represents a clinical state of metastatic disease that is limited in the number of metastatic sites and extent of disease, and amenable to metastasis‐directed intervention. The aim of this prospective study is to evaluate intervention to limited metastases in lung and/or liver.

    Survival Impact of Intervention To Distant Metastatic Lesions in Patients With Breast Cancer
    (Springer, 2022) Abidi, Hira; Ayoade, Oluwaseun; McAuliffe, Priscilla; Johnson, Ronald; Lee, Joanna; Keenan, Donald; Steiman, Jennifer; Sezgin, Efe; Soran, Atilla
    INTRODUCTION: Approximately 25% of patients (pts) with stage I - III breast cancer (BC) develop distant metastatic disease, a significant cause of mortality. The aim of this study is to evaluate whether intervention to metastatic lesions, in pts initially presenting with stage I–III BC, impacts overall survival (OS) and post-distant recurrence survival (PDRS). METHODS: This is a singleinstitution retrospective study of 201 pts with stage I–III BC, who subsequently develop metastatic lesions to the liver, lung, and/or bone, from 2006-2016. The cohorts included pts receiving intervention to their metastases (IM, n=100) versus no intervention to their metastases (NI, n=101). Two pts in the IM group were lost to follow up and excluded from the survival analysis. The primary study outcomes are OS and PDRS. The characteristics of the pts were compared with X2 test. OS curves were calculated by Kaplan-Meier method and multivariable analysis by Cox regression. Statistical significance was set at p< 0.05.

    Intervention for Hepatic and Pulmonary Metastases in Breast Cancer Patients: Prospective, Multi-Institutional Registry Study-Imet, Protocol Mf 14-02

    Background: One fourth of early-stage breast cancer cases become metastatic during the follow-up period. Limited metastasis is a metastatic disease condition in which the number of metastatic sites and the extent of the disease both are limited, and the disease is amenable to metastatic intervention. This prospective study aimed to evaluate intervention for limited metastases in the lung, liver, or both. Methods: The study enrolled luminal A/B and/or human epidermal growth factor receptor 2 (HER2)-neu+ patients with operable lung and/or liver metastases in the follow-up assessment after completion of primary breast cancer treatment and patients with a diagnosis of metastasis after 2014. Demographic, clinical, tumor-specific, and metastasis detection-free interval (MDFI) data were collected. Bone metastasis in addition to lung and liver metastases also was included in the analysis. The patients were divided into two groups according to the method of treatment for metastases: systemic therapy alone (ST) group or intervention (IT) group.

    Development of a Functional Chocolate Using Gamma-Amino Butyric Acid Producer Lacticaseibacillus Rhamnosus Nrrl B-442
    (Elsevier, 2022) Özer, Merve; Öztürk, Burcu; Hayaloğlu, Ali Adnan; Tellioğlu Harsa, Şebnem
    The human microbiota is influenced by the immune and nervous systems of the host. Gamma-aminobutyric acid (GABA) is known as bioactive compound and it has important physiological functions, such as anti-hypertensive and antidepressant activities. Lactic acid bacteria (LAB), especially Lactobacillus species are known as the most important GABA producers because of the food-grade nature. The purpose of this study is to develop a functional chocolate using microencapsulated GABA producer Lacticaseibacillus rhamnosus NRRL B-442 strain for patients having an anxiety disorder. Water-in-oil emulsion technique was conducted for microencapsulation using whey-pullulan complex. Microencapsulated and free L. rhamnosus cell counts were 6.75 and 7.20 log CFU/g in chocolates, respectively, at the end of 60 days. During simulated in vitro digestion analysis, survival rate of microencapsulated bacteria in chocolate samples was found at higher percentage (87%) than free bacteria (75%). Furthermore, microencapsulated L. rhamnosus did not affect the physical, chemical, and sensory properties of chocolate. Consequently, L. rhamnosus with the highest GABA producing capability may provide insight for an anxiety disorder patient, since this strain has been thought as having a therapeutic effect. A new functional food model was developed for “GutBrain Axis” phenomena since the chocolate could be accepted as a good carrier for GABA producer bacteria.
