Prenylated indole diketopiperazine alkaloids from a mangrove rhizosphere soil derived fungus Aspergillus effuses H1-1

One new prenylated indole diketopiperazine alkaloid, named dihydroneochinulin B (1), one known spiro-polyketide-diketopiperazine hybrid cryptoechinuline D (2) and three related known metabolites didehydroechinulin B (3), neoechinulin B (4) and auroglaucin (5) were isolated from the mangrove rhizosphere soil derived fungus, Aspergillus effuses H1-1. The structures were assigned by detailed spectroscopic analysis. The enantiomers of cryptoechinuline D (2) were separated to be (+)-cryptoechinuline D (2a) and (?)-cryptoechinuline D (2b) by chiral HPLC, and their absolute configurations were determined by ECD analysis. The cytotoxic effects of the compounds were preliminarily evaluated on P388, HL-60, BEL-7402 and A-549 cell lines by SRB or MTT methods, and compounds 2, 2a and 3 showed significant activities.     

显微CT技术对颌骨骨小梁解剖结构的测量及其准确性评价

目的：应用显微CT(micro-CT)测量颌骨解剖结构,探讨micro-CT测量的准确性。方法：将9具尸体的下颌骨标本分为髁状突组（3个标本,骨小梁结构均匀）和下颌骨体部组（5个标本,骨小梁结构不均匀）,图像分析软件建立总共30个有效容(VOI),每组各15个。计算每个像元大小的每个参数的平均值和标准差,并用方差分析判...     

人牙龈成纤维细胞原代培养及冻存和复苏

背景：牙龈成纤维细胞是牙龈固有结缔组织层中主要的细胞,在许多生理和病理过程中起着重要作用。目的：对人牙龈成纤维细胞进行原代培养、鉴定、冻存及复苏。方法：采用组织块培养法培养人牙龈成纤维细胞,并进行形态学和免疫学鉴定。对人牙龈成纤维细胞进行冻存与复苏,倒置显微镜下观察细胞形态变化。结果与结论：人牙龈成纤维细胞原代培养成功率为86.7%,细胞呈梭形或纺锤形。免疫组织化学鉴定抗波性蛋白抗体染色阳性,抗角蛋白抗体染色阴性,为中胚层来源的成纤维细胞。牙龈成纤维细胞冻存与复苏成功,细胞经2次传代后生物学性状与原代相似。提示采用组织块培养法培养原代人牙龈成纤维细胞及冻存与复苏方法可行。     

Functional Abilities of an International Post-Stroke Population: Standard Assessment of Global Everyday Activities (SAGEA) Scale

Background and ObjectivesFunction is an important outcome after stroke; traditional assessments may not capture functional deficits important to patients. We examined the validity of the Standard Assessment of Global Everyday Activities (SAGEA), a patient-reported outcome that assesses activities important to patients and for use in international clinical trials.MethodsThe NAVIGATE-ESUS trial evaluated rivaroxaban compared to aspirin in preventing recurrent stroke in 7213 participants. The Modified Rankin Scale (mRS), the National Institutes of Health Stroke Scale (NIHSS), and the SAGEA were collected at entry. Chi square tests were used to compare proportions and Spearman rank correlations were used to compare between measures. SAGEA was compared to the Modified Frailty Index (MFI) and the occurrence of infarct to examine criterion validityResultsParticipants were 67 years, 2/3 were male, and at baseline 30% had no disability and 58% had slight disability according to mRS scores. SAGEA was weakly correlated with the mRS (r=0.37), the NIHSS (r=0.29) and the MFI (r=0.30). Of the 2154 with an mRS score of 0, 61% reported difficulty on the SAGEA. The largest discrepancies between SAGEA and other measures were because of cognitive functional deficits detected by the SAGEA that were not identified on other assessments. A larger number of MRI identified infarcts (acute and covert) were associated with a higher SAGEA score (p=0.007).ConclusionsThe SAGEA is a simple, globally applicable measure of cognitive and functional abilities that identifies issues that other commonly used assessments of disability and function do not capture.
