Bioactive flavonoids from Flos Sophorae
AbstractThree new flavonoid glycosides —soyaflavonosides A (1), B (2), and C (3) —together with 23 known ones were obtained from the 70% EtOH extract of Flos Sophorae (Sophora japonica, Leguminosae). Their structures were elucidated by chemical and spectroscopic methods. Among the known isolates,14,18,20,22, and26 were isolated from the Sophora genus for the first time;12,19,24, and25 were obtained from the species firstly. Moreover, NMR data for compounds18 and26 are reported for the first time here. Meanwhile, compounds4,8–13,15,16,19,21, and22 presented obvious inhibitory effects on TG accumulation in HepG2 cells. Analysis of the structure –activity relationship indicated that all of the quercetin glycosides examined in this study possess significant activity that is not significantly influenced by the amount of glycosyl present, whereas increasing the amount of glycosyl reduced the activities of isorhamnetin glycosides and orobol. In addition, a high dose (30 μmol/l) of kaempferol was found to inhibit HepG2 cell growth, while a low dose (10 μmol/l) was observed to decrease TG accumulation.
DiscussionMCI prevalence varied among Hispanic/Latino backgrounds, but not as widely as reported in the previous studies. CVD risk and depressive symptoms were associated with increased MCI, whereas APOE4 was not, suggesting alternative etiologies for MCI among diverse Hispanics/Latinos. Our findings suggest that mitigating CVD risk factors may offer important pathways to understanding and reducing MCI and possibly dementia among diverse Hispanics/Latinos.
CONCLUSIONS: Local application of sevoflurane in the wound bed appears to exhibit analgesic, antimicrobial, and positive healing effects. It could be a promising alternative treatment to be included as a therapeutic option for wound care. PMID: 31730517 [PubMed - in process]
CONCLUSIONS: Cutaneous vasculopathy related to the skin, such as livedo reticularis and ulcers of torpid evolution due to cutaneous vasculopathy are extremely rare. Thus, it is necessary to include skin ulcers as one of the phenotypic manifestations of NF-1. PMID: 31730516 [PubMed - in process]
CONCLUSIONS: The authors suggest stasis mucinosis and OALM represent the spectrum of euthyroid mucin depositional disease in varying clinical settings. PMID: 31730515 [PubMed - in process]
CONCLUSIONS: From this case report, the authors believe NPWTi-d may be more effective in cases with intractable ulcers associated with infection that need better granulation. PMID: 31730514 [PubMed - in process]
Authors: Roshangar L, Soleimani Rad J, Kheirjou R, Reza Ranjkesh M, Ferdowsi Khosroshahi A Abstract Burn wounds are one of the main causes of skin damage. Based on World Health Organization statistics, almost 300 000 people worldwide die of burns each year. In severe burns, the cells and blood vessels are often injured and the blood supply to the wound is disturbed. Many factors such as oxygenation, infection, aging, hormones, and nutrition potentially can influence burn progression and disrupt repair with unbalanced release of various growth factors and cytokines. Different treatment approaches such as dressings a...
CONCLUSIONS: An illustrated guide for dressing application in burn wounds was developed and validated for content by an expert panel. PMID: 31730512 [PubMed - as supplied by publisher]
CONCLUSIONS: This is the largest cohort reported in the literature of patients with frostbite injuries treated with HBOT. Hyperbaric oxygen therapy may show positive impact on the demarcation level of frostbite and, despite the common side effects, it generally causes no long-term sequelae.

CONCLUSIONS: This is an easily reproducible and safe technique for effluent control in patients with Björk grade 4 abdomen with established EAF. PMID: 31730510 [PubMed - as supplied by publisher]
CONCLUSIONS: These results suggest the importance of arterial-arterial connections such as the pedal arch to the healing potential of foot and ankle wounds after STSG in this high-risk patient population. PMID: 31730509 [PubMed - as supplied by publisher]
