The jelly secreted by the oviduct of Rana pipiens has been analyzed histochemically and biochemically. Histochemical techniques show that the jelly contains neutral carbohydrates and a protein moiety. Colorimetric estimation reveals that the jelly contains protein and also appreciable quantities of hexose and hexosamine. Sialic acid is present. Chromatographic methods were employed to identify ...

Sinking of gelatinous zooplankton biomass is an important component of the biological pump removing carbon from the upper ocean. The export efficiency, e.g., how much biomass reaches the ocean interior sequestering carbon, is poorly known because of the absence of reliable sinking speed data. We measured sinking rates of gelatinous particulate organic matter (jelly-POM) from different species o...

the aim of this study was to compare the effects of using different levels of royal jelly in semen extender on viatal characteristics of goat sperm after freezing. semen was collected from four adult bucks twice a week and samples pooled together. sperm samples (six repeats) containing royal jelly in four levels (0.5, 1, 1.5 and 2%) had been frozen. after semen samples freezing – were thawed an...

This work describes optimization of a field-tested jelly tracking system to enable AUV deployment under tight energy constraints. Inspired by research in marine biology, the task of long duration jellyfish tracking poses both an opportunity and a significant challenge for the AUV community. AUVs offer the potential for extended midwater deployments, enabling observation of natural phenomena dur...

Seed storage proteins of plants commonly comprise several groups of multiple isoforms encoded by gene families. From about 300 expressed sequence tag (EST) clones in maturing jelly fig (Ficus awkeotsang Makino) achenes, gene families encoding precursor polypeptides of two storage protein classes, including six 11S globulin isoforms and two 2S albumin isoforms, were identified. Complete sequence...

Inovasi dan pemasaran suatu produk merupakan prioritas bagi kemajuan bisnis. Salah satu unggulan UMKM Kreatif Klampok Kasri adalah permen jelly yang menjadi salah potensi agar pendapatan anggota meningkat. Akan tetapi, pandemi COVID-19 berdampak negatif pada volume penjualan bisnis jelly. Selain itu, kendala dihadapi dalam mengembangkan produknya yaitu terbatas dimana kemasan kurang menarik ser...

Objective(s):Mesenchymal stem cells (MSCs) derived from Wharton’s jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. Materials and Methods: MSCs were isolated from human Wharton’s jelly and treated with BMP4, retinoic acid (RA) or co-cultured on huma...

An aqueous extract of royal jelly from Apis mellifera produced hypoglycemia when injected into larvae of Manduca sexta. Application of specific radioimmunoassay to the partially-purified extract showed that royal jelly contains several insulin-like peptides, the major immunoreactive component of which has an apparent mol. wt similar to that of bovine insulin. These results suggest the existence...
