Background: Chondrocytes in the growth plate(GP) undergo increases in volume during different cascades of cell differentiation during longitudinal bone growth. The volume increase is reported to be the most significant variable in understanding the mechanism of long bone ***: Forty-five postnatal Sprague-Dawley rat pups, 7-15 days old were divided into nine age groups(P7-P15). Five pups were allocated to each group. The rats were sacrificed and tibia and metatarsal bones were harvested. Bone lengths were measured after 0, 24, 48, and 72 hours of ex vivo incubation. Histology of bones was carried out, and GP lengths and chondrocyte densities were ***: There were significant differences in bone length among the age groups after 0 and 72 hours of incubation. Histological sectioning was possible in metatarsal bone from all age groups, and in tibia from 7-to 13-day-old rats. No significant differences in tibia and metatarsal GP lengths were seen among different age groups at 0 and 72 hours of incubation. Significant differences in chondrocyte densities along the epiphyseal GP of the bones between 0 and 72 hours of incubation were observed in most of the age ***: Ex vivo growth of tibia and metatarsal bones of rats aged 7-15 days old is possible, with percentage growth rates of 23.87 ± 0.80% and 40.38 ± 0.95%measured in tibia and metatarsal bone, respectively. Histological sectioning of bones was carried out without the need for decalcification in P7-P13 tibia and P7-P15 metatarsal bone. Increases in chondrocyte density along the GP influence overall bone elongation.

Physico-Chemicals Characterization of Quercetin from the <i>Carica papaya</i>Leaves by Different Extraction Techniques

引用

Open Journal of Physical Chemistry 2021年第3期11卷 129-143页

作者： Muhammad Hidhir Khawory Mohd Ferdaues Mohd Subki Mohd Anuar Shahudin Nurul Hidayatul Afifah Saufi Sofian Nur Hidayah Latif Nurul Hanim Salin Siti Zuraidah Mohamad Zobir mohamed Ibrahim noordin Malaysian Institute of Pharmaceutical and Nutraceutical (IPharm) Pulau Pinang Malaysia National Institutes of Biotechnology Malaysia (NIBM) Selangor Malaysia PICOMS International University College Kuala Lumpur Malaysia

Carica papaya leaf extracts from four different extraction methods (cold-water, hot-water, sonication and supercritical fluid), were characterized using physico-chemical analysis. Sonication extraction showed the highest percentage yield of crude extracts (6.76%) and the lowest from the supercritical fluid extraction (1.83%). The Infrared (IR) spectrum of cold-water extract demonstrated the most similarity of functional group to quercetin. Likewise, the thermal analysis indicated that cold-water extract gave a quite similar Endothermic peak to quercetin with the obtained value which was 137°C and onset value which was 118°C. The liquid chromatography (LC) profile indicated that only the cold-water extract exhibited 0.203 ppm of quercetin.
