In this study, black cumin oil (BCO) oleogel was produced using natural waxes (beeswax: BW, sunflower wax: SFW, and carnauba wax: CW) to offer a healthy alternative to shortening. Oiling-off was observed only in the BW oleogel (3.88 ± 0.02%).The CW oleogel had the lowest E a (354.82 kJ/mol), indicating greater resistance to thermal degradation. The highest G′ and G″ were observed in the CW oleogel, while the lowest was observed in the BW oleogel. All oleogel samples displayed weak gel properties (tan δ > 0.1), but the lowest tan δ value belonged to the CW oleogel (0.12).After 4 weeks of storage, the peroxide values of the oleogels were lower than those of bulk oil (p < .05). Finally, the oxidation results showed that the BCO structuring by the waxes effectively protected it from oxidation over eight weeks of storage. Novelty impact statement:The most important innovation of the present study was to investigate the effect of BCO oleogelation on the stability of thymoquinone, the main phenolic compound of BCO. The BCO oleogels had higher thymoquinone content during the first half of the storage period compared with bulk BCO, showing that the oleogel network provides a protective effect against oxidation and thermal degradation.

In this study, physicochemical, rheological (steady, dynamic, and creep/recovery), and textural properties of yoghurt/molasses blends (0, 5, 10, and 15% molasses) were investigated. The blends showed shear thinning behavior, as described by Ostwald de Waele model (R(2) ( )≥ 0.955). Consistency coefficient value (K) of the blends decreased with increasing molasses concentration in the sample. Storage modulus (G') of blends was higher than loss modulus (G″), exhibiting weak gel-like behavior. Molasses addition decreased G' and G″ values. Temperature sweep tests indicated that blends followed Arrhenius relationship. A modified Cox-Merz rule was applicable using shift factors. Compliance values (J(t)) increased as molasses concentration increased, revealing that deformation stability and internal viscosity (η1) decreased with concentration. Creep behavior was characterized using Burger model. Obtained J data as a function of time could be satisfactorily fitted to Burger model (R(2) ( )≥ 0.994). The final percentage recovery of blends remarkably decreased with the increase of molasses concentration. Firmness, consistency, cohesiveness, and viscosity index values decreased with molasses addition. According to the results of the current study, molasses amount to be added to the yoghurt should be determined regarding rheological properties since resistance of the sample to deformation decreased with increase in molasses concentration.

Purple basil is widely used medicinally and aromatically due to its essential oil properties, and it is a plant that stands out with its antibacterial, antimutagenic and antioxidant properties. It has been determined that purple basil has positive effects on health such as appetizing, insomnia, sputum, diuretical and antispasmodic. Purple basil contains high concentrations of anthocyanins and with these properties it stands out as a potential new source of stable red pigments for the food industry. In recent years, it has been seen that purple basil has been processed into different products such as tea and sherbet in order to benefit from its functional properties. With the processing of purple basil into different products, it is seen that the consumption of basil and basil products has increased by consumers. In this study, purple basil sherbet samples were concentrated at different voltage gradient values (14, 17 and 20 V/cm) under atmospheric conditions with ohmic heating up to 25% soluble solid content (SSC) and the changes in their rheological properties during the concentration process was investigated. The changes in the rheological properties of the purple basil samples were determined in the range of 1-148 s-1 shear rate values and measurement temperature was 25°C. The compatibility of different rheological models (Newton, Power-Law and Herschel-Bulkley) to the experimental data was statistically evaluated to determine the flow behavior index of the purple basil sherbet samples. It has been determined that the shear stress values increased as the shear rate values increased in all the process conditions. Similarly, at the same shear rate values, it was determined that the shear stress values increased as the SSC values increased. It has been determined that the best suitable rheological model was Herschel-Bulkley Model for all purple basil sherbet concentrates. It is thought that the results obtained will provide important data to the food and machinery industry for the installation of pilot and industrial scale ohmic heating systems.

Bununla birlikte intravenöz olarak Paget hastalığı, bazı kanserlerin Turkiye Klinikleri J Dental Sci 2015;21(3) 255 İntravenöz Bifosfonat Kullanımına Bağlı Olarak Mandibulada Gelişen Çene Kemiği Nekrozunun Tedavisi Ö ÖZ ZE ET T Bifosfanatlar, kemik turnoverını suprese eden ve osteoporoz gibi bening kemik hastalıkları ve iskeletal yapıyı etkileyen malignensi durumlarını önlemek için yaygın olarak reçete edilen ilaç-lardır. Çenelerin bifosfanat ilişkili osteonekrozu maksilla ve mandibuladaki kemiğin ekspoz olmasıyla karakterize bir durumdur. Bu hastalık; dental implant uygulamaları, apikal rezeksiyon, periodontal cerrahi uygulamalar ve diş çekimi gibi invaziv cerrahi işlemler sonrası ya da alveol kemiğin kendiliğinden ekspoz olması sonucu meydana gelmektedir. Olgumuzda; meme kanseri nedeniyle intravenöz bifosfanat tedavisi görmüş 41 yaşında kadın hasta, sol mandibular premolar ve molar bölgesinde diş çekimi sonrası meydana gelen ağrı ve enflamasyon nedeniyle kliniğimize baş-vurmuştur. Radyografik ve klinik incelemeler sonucu bifosfanat ilişkili osteonekroz tanısı konularak, antibiyotik baskısı altında nekroz alanı cerrahi girişimle temizlenip, iyileşmeyi hızlandırmak için ozon terapisi uygulanmıştır. Nekroz alanının iyileşmesini desteklemek amacıyla hasta hiperbarik oksijen tedavisine yönlendirilmiştir. Bu tedavi prosedürleri sonrası ilgili alanda yeni kemik oluşumu gözlenmiştir. Günümüzde, çene kemiğinin bifosfanat ilişkili osteonekroz olgularında kesin bir tedavi prosedürü bulunmamakla birlikte olgumuzda da gösterildiği üzere hiperbarik oksijen tedavisi bu olgularda umut verici olabilir.A An na ah ht ta ar r K Ke el li im me el le er r: : Çenenin bifosfonat ilişkili osteonekrozu; hiperbarik oksijenasyon; ozon; zoledronik asit A AB BS ST TR RA AC CT T Bisphosphonates are drugs that suppress bone turnover and are commonly prescribed to prevent skeletal related events in malignancy and for benign bone diseases such as osteoporosis. Bisphosphonate-induced osteonecrosis of jaws refers to a condition characterized by exposure of bone in the mandble or maxilla. The disease presents as exposed alveolar bone that occurs spontaneously or becomes evident following on invasive surgical procedure such as tooth removal, periodontal surgery, apicoectomy, or dental implant placement. In our case, 41-year-old woman patient with breast cancer referred to our clinic because of continued pain and inflammation on left mandible after the extraction. After clinical and radiologic examination, she has been diagnosed with biphosphonate induced osteonecrosis of the jaw. Under the pressure of antibiotic, the necrosis area was cleaned surgically and ozone therapy was applied to accelerate the healing. In order to support the healing of the necrosis area, patient have been directed by hyperbaric oxygen therapy. After these treatment procedures, secestre formation in bone and new bone formation ...
