  A patient with type I CD36 deficiency whose myocardium accumulated123I-BMIPP after 4 years

  摘要：

  A 73-year-old man with aortic regurgitation was examined by I-123-alpha -methyl-p-iodophenylpentadecanoic acid (BMIPP) myocardial single photon emission computed tomography (SPECT) in 1995. Myocardial accumulation was not evident on either the early or the delayed image obtained 15 minutes and 3 hours, respectively, after injecting I-123-BMIPP. Flow cytometric analysis of CD36 expression in monocytes and platelets identified a type I CD36 deficiency. The patient was hospitalized for severe heart failure in 1999. Upon admission, the cardiothoracic ratio on chest Xrays was 73%, and the left ventricular end-diastolic diameter on echocardiograms was enlarged to 77 mm. On the second day, we performed I-123-BMIPP myocardial SPECT. Myocardial accumulation was evident in the delayed, but not in the early image. We repeated I-123-BMIPP myocardial SPECT on the 10th day after admission. Myocardial accumulation was evident on both early and delayed images. Tc-99m-tetrofosmin myocardial SPECT was immediately performed after I-123-BMIPP myocardial SPECT to distinguish myocardial from pooling images in the left ventricle, but, because the images from both 99mTc-tetrofosmin and I-123-BMIPP myocardial SPECT were idential, we considered that the 123I-BMIPP myocardial SPECT images reflected the actual myocardial condition.The CD36 molecule transports long-chain fatty acid (LCFA) on the myocardial membrane, but I-123-BMIPP scintigraphy does not show any myocardial accumulation in patients with type I CD36 deficiency, indicating that myocardial LCFA uptake occurs through CD36 on the human myocardial membrane. Even though our patient had type I CD36 deficiency, BMIPP was uptaken by the myocardium during heart failure, suggesting a variant pathway on the human myocardial membrane for LCFA uptake.

  compounds screened for activity, 9 phenylpropanoates, 3 cinnamates, and 4 benzoates were found to be highly active antifeedants. To understand the structure-activity relationships of these compounds, a multivariate analysis study was performed. A number of molecular and substituent descriptors were calculated and correlated to results from two-choice feeding tests with H. abietis. Three local models were developed

  在松树象鼻虫（Hylobius abietis）上测试了主要是苯丙酸酯，肉桂酸酯和苯甲酸酯的拒食活性。在筛选出活性的105种化合物中，发现9种苯基丙酸酯，3种肉桂酸酯和4种苯甲酸酯是高活性的拒食剂。为了了解这些化合物的构效关系，进行了多变量分析研究。计算了许多分子和取代基描述子，并将其与由过双歧杆菌进行的二选饲喂试验的结果相关联。建立了三个具有良好内部预测能力的局部模型。外部测试集显示出中等预测性。通常，低极性，小尺寸和高亲脂性是具有良好拒食活性的化合物的特征。
