Abstract

Extraction and partial characterization of lectin from Indonesian Padina australis and Padina minor had been carried out. The crude extract of the P. australis and P. minor were examined for hemagglutination activity (HA) using native and trypsin-treated of rabbit and human A, B, O type erythrocytes. Both extracts agglutinated all of the trypsin-treated erythrocytes tested in the HA assay. Strong HA was detected in the crude extract of P. minor with trypsin-treated of human type A and O erythrocytes. However, the sugar-binding specificity study through the quantitative hemagglutination inhibition (HI) assay showed that P. minor extract could not specifically recognize the glycans tested. Apparently, the HA of the P. minor was more due to its co-extracted polyphenols content than its lectin content. On the other hand, the HI assay showed that asialo transferrin human (aTf) and asialo porcine thyroglobulin (aPTG) were the most powerful in inhibiting the HA of P. australis. Those indicated that P. australis protein extract was able to specifically recognized aTf and aPTG. The stability of P. australis and P. minor HA over various temperatures, pH ranges, and divalent cations studies showed that the P. minor HA was stable on a wide range of pH and temperature; not affected by the presence of EDTA, but decreased by Ca2+ and Mg2+ additions showed that P. minor protein extract  was not a metallic protein. The HA of P. australis decreased at 60 oC and was inactivated at 90 oC; increased at strong acidic (pH 3 4) and strong basic (pH 9 10) and dependent by the presence of either EDTA or Ca2+ and Mg2+ divalent cation.

Abstract

Lektin (hemagglutinin) tersebar secara luas di alam dan memiliki potensi yang baik terkait denganprospeksinya dari alga laut. Sifat terpenting lektin adalah kemampuannya untuk mengikat karbohidrat danmengaglutinasi sel. Lektin dapat berguna sebagai alat yang mudah digunakan untuk menunjukkan perbedaanstruktur karbohidrat dan mempunyai berbagai macam aktifitas biologis terkait dengan pengikatan daninteraksinya dengan karbohidrat, sehingga terdapat ketertarikan yang besar dalam upaya untuk menemukan danmengisolasi lektin baru dari perspektif penggunaan lektin, khususnya dalam bidang glycomics dan medis. Fraksikasar lektin dari enam spesies alga hijau genus Codium disiapkan dan diuji aktifitas hemaglutinasinya denganmenggunakan trypsin-treated rabbit erythrocytes. Hasil positif pada limaspesies alga hijau genus Codium yangdiuji dalam hemagglutination assay mengindikasikan keberadaan lektin (hemagglutinin) pada spesies-spesiestersebut. Namun demikian, masih diperlukan penelitian lebih lanjut mengenai pemurnian lektin dan karakterisasisifat biokimianya.

Abstract

Introduction: Chocolate is a widely consumed food, particularly by children. It is often considered a contributing factor to the development of dental caries due to its high sugar content, which can lead to the formation of dental caries. Aim: This study aimed to determine whether consuming dark chocolate sweetened with sucrose, xylitol, and stevia would reduce saliva acidity in children aged 10-12 years. Methods: Twenty-one children aged 10-12 years were given dark chocolate with three sweeteners: 30% sucrose, 30% xylitol, and 1% stevia. The subjects' saliva was collected 10 minutes after chewing chocolate with sucrose on day 1, chocolate with xylitol on day 2, and chocolate with stevia on day 3 for 30 seconds and then measured by a pH meter. The measurement was repeated thrice. Result: The difference in mean saliva pH before and after treatment with the three types of chocolate were analysed using the One-way ANOVA test.  A decline in pH was observed in all treatment groups; however, the most significant decrease was observed in the sucrose chocolate group (0.34 ± 0.12), followed by the stevia chocolate group (0.26 ± 0.09), and the least significant decrease was observed in the xylitol chocolate group (0.14 ± 0.07). Conclusion: A statistically significant difference was observed in the decrease in saliva acidity among children aged 10-12 years who consumed dark chocolate containing sucrose, xylitol, and stevia

Abstract

Avocado starch has gained attention as a potential bio-based material due to its unique features that make it suitable for forming biofilms. This work thoroughly examines the changing field of research focused on using avocado starch for biofilm applications. It uses VOSviewer, a tool for analyzing bibliometric data, to uncover important insights using a database of Scopus-indexed journal publishers. This study aimed to determine research trends on the use of avocado starch for biofilm production. The Scopus database collected information on research trends in the use of avocado starch for biofilm production. To obtain search results, subject categories with titles, keywords, and abstract criteria from the use of avocado starch extraction, biofilm/bioplastic production, and biocomposite were used as a reference. Using VOSviewer, search result extraction was performed. The results of bibliometric mapping were then further evaluated. The findings of the bibliometric study are demonstrated through network visualization, overlay visualization, and density visualization. The findings indicate that starch produced from avocados has the potential to be a viable resource for manufacturing biofilms. However, further investigation is required to enhance the overall quality of the produced biofilm.
