Comparison of essential oil composition between Angelica gigas and Angelica acutiloba
Park,C,H,Juliani,H,R,Park,H,W,Yu,H,S,Simon,J,E 한국자원식물학회 2003 Plant Resources Vol.6 No.3
Two kinds of Angelica belong to Umbelliferae collected, the one is Angelica gigas that is inhabitant in Korea and the other is Angelica acutiloba that is indigenous in Japan at the field of Snyder Research and Extension Farm Rutgers University, New Jersey and was analyszed by GC and GC/MS. The composition of the essential oil of the different aerial parts of the Angelica has been studied. The oil yields obtained upon hydrodistillation were 0.18% (v/w) in Korean Angelica and 0.44% (v/w) in Japanese Angelica on dry root weight basis. By the growing stage in the Rutgers greenhouse condition, leaf and root of essential oil content a little decreased on 9 months later than 4 months later except for Angelica gigas leaf. Both of Angelica showed that amounts of essential oil content presented in order of leaf > petiole > root according to different plant part. The analysis of the essential oil from Angelica root led to the identification of 14 constituents totaling 64% in Korean Angelica and 13 constituents totaling 68% in Japanese Angelica. The major constituents of the Angelica root essential oil were ligustilide (47 %) and gamma terpi (14 %) in Korean Angelica, and alpha pinei (32 %) and nonane (25 %) in Japanese Angelica

The development of new biomaterials with improved properties is a trend in tissue regeneration. In this way, an innovative approach is employed in this work for obtaining polymer fibers coated with nanoparticles resulting from the simultaneous application of poly (lactic acid) (PLA)/polycaprolactone (PCL) electrospinning and bioactive particles from an amorphous multicomponent silica–calcium–phosphorus system (AMS) electrospraying. The osteogenesis was evaluated in vitro and in vivo using male rats, in which total protein, alkaline phosphatase, and biological performance through histological and histomorphometric analysis were discussed. The morphological results assessed by scanning electron microscopy showed a mesh of PLA/PCL fibers associated with AMS. The spraying of 17.44% of AMS particles in the PLA/PCL electrospun fibers decreased the Young’s modulus and tensile strength. However, the amount of AMS particles sprayed was enough to promote a reduction of 17.8% in the measured contact angle values. Phosphatase alkaline higher mean value was also observed in the fibers when in contact with the AMS, but nonstatistical difference was observed (p > 0.05). It was possible to observe the presence of mineralized nodules deposited on the bottom of the plate and between the fibers. The newly formed bone into defect filled with PLA/PCL-AMS fibers was higher than that observed in the control group. These findings suggest PLA/PCL-AMS fibers as a multifunctional composite system that may be attractive for both bone and dental tissue engineering applications.
Sunlight Incidence, Vitamin D Deficiency, and Alzheimer's Disease
Alice Barros Camara,Iara Dantas de Souza,Rodrigo Juliani Siqueira Dalmolin 한국식품영양과학회 2018 Journal of medicinal food Vol.21 No.9
Vitamin D (VD) deficiency is a growing problem, affecting a significant portion of the population in many countries. VD deficiency may be related to several diseases, including Alzheimer's disease (AD). This study aimed to review the relationship between VD deficiency and AD. We describe the proteins involved in AD pathogenesis and how those proteins can be influenced by VD deficiency. We also investigated a relationship between AD death rate and solar radiation and we found an increased AD death rate in countries with low sunlight. It was also observed that amyloid precursor protein, ryanodine receptor, mammalian target of rapamycin complex 1, and receptor for advanced glycation end products are associated with a worse prognosis in AD. While the Klotho protein, phosphatase and tensin homologue, and VD receptor are associated with a better prognosis in the disease. The literature suggests that decline in VD concentrations may be involved in the establishment and progression of AD. According to sunlight data, we can conclude that countries with low average sunlight have high AD death rate.
