RESULTS: Scoby from black, green and oolong tea kombucha fermentation was assessed for its hydrocolloid effects in mango jam-making through evaluation of physicochemical, textural and sensory characteristics. Quality of jam was significantly improved with water activity reduction up to 22.22% to 0.679, moisture content reduction up to 37.06% to 19.92%, and a pH drop up to 5.9% to 3.19 with the use of 20 to 100 g kg-1 scoby. In colour analysis, presence of scoby led to a brighter jam due to higher L * values from 30.98 to a range of 31.82 to 40.83. Texture of jam with scoby gave higher gel strength and adhesiveness, with the most prominent effects from the black tea kombucha. Overall acceptability in sensory test scoring was above 70% on a nine-point hedonic scale with the 40 g kg-1 green tea kombucha scoby jam chosen as the most preferred.
CONCLUSION: Scoby gave significant contributions to jam stability, appearance and texture, showing potential as a clean-label food ingredient. © 2024 Society of Chemical Industry.
BACKGROUND: The Occlutech® PDA occluder is novel, self-shaping Nitinol wire device with PET (polyethylene terephthalate) patches integrated into the shank of the device to assure a better obturation of the ductus. The Occlutech® PDA occluder has undergone two design modifications.
METHODS: A prospective, non-randomized pilot study was started in November 2011. Thirty-three patients were included until April 2013. Patients weighing <6 kg or those with associated cardiac anomalies that required surgery were excluded. All patients were followed up by transthoracic echocardiography at 24 hr, 30 days, 90 days, 180 days, and 360 days after implantation. Residual shunt, left pulmonary artery (LPA) and descending aortic velocities were among the parameters assessed. All occluders were delivered via 6-8 F long sheaths and PDA closures were performed following standard techniques.
RESULTS: Thirty three patients (20 female/13 male), with a median age of 2 years (6 month to 38 years), and median weight of 9.3 kg (6-69.2 kg) were included. The narrowest median PDA diameter was 3mm (1.8-5.8 mm). All the 33 patients were closed successfully using Occlutech ductal occluder, 16 patients (48.4%) had immediate and complete closure on angiography. Within 24 hr, color Doppler revealed complete closure in 27patients (81.8%), 32patients (97%) at 30 days, and in 100% of patients at 90 days. All patients with a large PDA had immediate residual shunt which was closed at the 90-day follow-up. There was no device embolization, hemolysis, or obstruction to the LPA or descending aorta.
CONCLUSION: The new Occlutech® PDA is safe and effective. In patients with a large PDA complete closure tended to take longer time.
OBJECTIVES: To design and perform a simple surveillance on OLP patients based on colour-coded topography mouth maps (TMM).
MATERIALS AND METHODS: Three colour-coded TMM were employed: red for OLP in high risk oral mucosal sites, yellow for cases showing improvement and green for asymptomatic lesions at each recall visit. In this preliminary study, these were applied on 30 histologically confirmed OLP individuals attending the Oral Medicine Clinic at the Department of Oral Pathology, Oral Medicine and Periodontology, Faculty of Dentistry, University of Malaya. The sites and extent of OLP lesions were charted on either red, yellow or green TMM based on defined criteria. This surveillance evaluated OLP in relation to patientandapos;s age, race, gender, underlying systemic conditions, oral habits, initial onset of OLP, oral manifestations and presence/absence of clinically suspicious areas.
RESULTS: Study sample comprised 4 (13.3%) Malays, 9 (30.0%) Chinese and 17 (56.7%) Indians. Most OLP patients belong to the green TMM (n= 14, 46.6%) group followed by red (n= 11, 36.7%) and yellow (n= 5, 16.7%) groups. Of the 11 cases with red TMM, rebiopsy was performed on 4 cases but no dysplasia was detected. Any local confounding factors namely periodontal disease or faulty dental restorations were managed accordingly.
CONCLUSIONS: TMM is simple to use and aided the clinicians in terms of time saving and patient management. Hence, follow-up of OLP patients can be carried out more efficiently and appropriately. TMM can be used for surveillance of other oral precancerous lesions and conditions.
