The Amygdala Modulates Hippocampus-Dependent Context Memory Formation and Stores Cue-Shock Associations.

Preexposing rats to the context facilitates subsequent contextual fear conditioning. This effect depends on the hippocampus (J. W. Rudy, R. M. Barrientos, & R. C. O'Reilly, 2002). The authors report that inactivating the basolateral region of the amygdala (BLA) by injecting muscimol, a GABAA agonist, before or after preexposure reduced this effect. In contrast, bilateral injections of anisomycin, a protein synthesis inhibitor, into BLA did not impair the consolidation of the context memory. However, when injected after fear conditioning, anisomycin impaired consolidation of both contextual and auditory-cue fear conditioning. Results are consistent with 2 ideas about the amygdala's contribution to memory: (a) It modulates memory formation in other regions of the brain, and (b) it is a storage site for cue-shock associations.

Temperature and pressure effects on supercritical CO2 extraction of tomato seed oil

Tomato seed oil was extracted with supercritical carbon dioxide in a semibatch-flow extractor within the temperature range 313–343 K and the pressure range 10.8–24.5MPa. The extraction rates increased with pressure, but decreased with temperature increase because of the variation in solvent density and resultant differences in oil solubility. The fatty acid composition of the extracted oil was similar to that of soybean oil.

焦化防砂室内实验研究

油井防砂工艺技术的研究与发展对疏松砂岩油藏的正常开采至关重要.焦化防砂是通过向地层内注入热空气使原油在高温下发生氧化裂解生成焦炭从而将地层砂固结的一种防砂新技术.为了对该项技术进行全面系统的理论分析与评价,设计并制作了一套焦化防砂实验装置,利用该装置进行了焦化防砂室内实验研究.焦化效果以岩样的抗压强度进行评价,实验结果表明,影响焦化后岩样抗压强度的主要因素为空气最高温度、处理时间和空气流量.此外,对焦化处理后的岩样所作的岩样组成分析揭示出,稠油胶结机理为氧化作用使部分油分和胶质变成沥青质,沥青质受到高度的缩合作用而成为高分子量的甲苯不溶物.由于新生胶质的氧化比原生胶质的氧化困难得多,因此适合焦化防砂的油层,其原油必须含有一定量的原生胶质和沥青质.

Application of Rachinger''s method to separate overlapped doublets in the X-ray photoelectron spectrum

Rachinger's method of separating ₁ and ₂ doublets in X-ray emission spectra is applied for the first time to separate the superimposed doublets due to spin-orbit coupling. This method has been applied to separate closely lying doublets such as (Ag 4p_3/2and Ag 4p_1/2, (Ni 3p_3/2and Ni 3p_1/2) and (Cu 3p_3/2and Cu 3p_1/2). The intensities ratios of the separated peaks are measured and compared with the ratios obtained from a first-order calculation. An excellent agreement between the measured and calculated ratios are obtained. Residual background intensities compared with the estimated values are found to agree within certain uncertainties.     

乳腺癌中着丝粒蛋白CenpG的差异表达

用间接免疫荧光（IIF）验证了着丝粒蛋白CenpG的一种抗血清；通过对31例乳腺癌组织块及每一例病人的癌旁正常（非癌性）组织块蛋白提取物进行免疫印迹（Western blot）分析，发现多数情况下（71%）癌组织中着丝粒蛋白CenpG(95kD)过表达；在两例乳腺癌组织中还发现了一种能被CenpG抗血清识别的43kD蛋白质成分。结果表明，新近发现和命名的CenpG（或者还有其他相关成分）的差异表达可能与细胞恶性增殖有关。
