波动不对称(FA)是压力的随机性引发双侧完美对称偏离的现象,这是个体无力免受发展中不利因素(如早期营养不良)侵害的一个标志。比较个体口腔两侧牙齿的大小是一种测量 FA 的方法。本研究汇集了 10 个物种共 296 名个体的牙齿测量结果,测量对象包括黑猩猩(学名 Pan troglodytes)、猩猩(学名Pongo pygmaeus)、大猩猩(学名 Gorilla gorilla)、智人(学名 Homo sapiens),以及许多化石人。分析发现,猩猩样本牙齿的 FA 水平要显著低于大猩猩、黑猩猩、直立人、尼安德特人和智人样本的 FA 水平。而与之相反的是,智人与尼安德特人样本的牙齿 FA 水平要显著高于其它任何一种巨猿样本的 FA 水平。该文提出了有关缓和的选择压力的解释。

(La0.5Ce0.5)2Co7 and(Ce0.65Pr0.35)2Co7 compounds for magnetic refrigeration were studied by X-ray diffraction, ac susceptibility and isothermal magnetization measurements. X-ray powder diffraction shows that all the compounds have hexagonal Ce2Ni7-type structure. The Curie temperatures(TC) are 258 K and 222 K for(La0.5Ce0.5)2Co7 and(Ce0.65Pr0.35)2Co7 compounds, respectively. High coercivities(HC) of about 1.74 and 6.61 k Oe at 5 K with a smooth demagnetization curves were obtained for the(La0.5Ce0.5)2Co7 and(Ce0.65Pr0.35)2Co7 compounds, respectively. For an applied field change from 0 to 50 k Oe, the maximum(??SM) for(La0.5Ce0.5)2Co7 and(Ce0.65Pr0.35)2Co7 compounds are 0.52 and 0.67 j/(kg K), respectively.

本文研究了一种高强度铁基高温合金的中温脆断现象,即由晶界脆化而导致的塑性剧降。通过对合金的加工和热处理历史、显微组织和断口特点、显微成分的再分布、以及试验时环境介质的影响等因素的分析讨论,确定中温时的脆化是由于氧的渗入和晶界处胞状析出以及它们间交互作用所造成。探索了一些防止晶界脆化的措施,使合金固有的良好塑性得以恢复。研究得出,氧强烈地促进合金中胞状析出而应力进一步加速此过程。根据所得试验结果,提出了新的脆化机制

逃避理论预测,不逃跑若增大适合度代价则导致逃跑启始距离加长,逃跑若增大代价则导致逃跑启始距离缩短。逃跑路径和去向等受生境结构影响。作者通过模拟捕食者逼近研究喀拉哈里树石龙子(Trachylepis sparsa)和黑环蜥(Cordylus niger)逃避策略和风险因子对逃跑启始距离的影响。与迂回逼近相比较,直接逼近不仅提高蜥蜴逃跑几率还能缩短其逃跑启始距离。喀拉哈里树石龙子在两种逼近方式下的逃跑启始距离有显著差异,这种差异对黑环蜥而言是边缘性的。喀拉哈里树石龙子以树为避所,树上个体可逼近的距离短于地面个体;快速逼近地面个体的逃跑启始距离比慢速逼近更长。习惯于有人环境的黑环蜥逃跑启始距离比人迹罕至环境中的个体更短。地面喀拉哈里树石龙子多遁至树上而很少逃入倒木或倒伏编巢中。树上喀拉哈里树石龙子通常奔逃至远侧和高处,有时遁入树洞或编巢中;黑环蜥则逃入石缝中。所有发现都证实逃避理论中有关逃跑启始距离的预测。逃跑策略的种间差异表明每一种蜥蜴都利用其生境中逃跑路径和避所的有利条件。在风险不同的生境中,生境结构可影响逃跑启始距离,似乎对逃跑策略亦有重要影响。

AIM: To assess the effect of our novel cell-permeable nuclear factor-kappaB (NF-κB) inhibitor peptide PN50 in an experimental model of acute pancreatitis. PN50 was produced by conjugating the cell-penetrating penetratin peptide with the nuclear localization signal of the NF-κB p50 ***: Pancreatitis was induced in male wistar rats by administering 2×100 μg/kg body weight of cholecystokininoctapeptide (CCK) intraperitoneally (IP) at an interval of 1 h. PN50-treated animals received 1 mg/kg of PN50 IP 30 min before or after the CCK injections. The animals were sacrificed 4 h after the first injection of ***: All the examined laboratory (the pancreatic weight/body weight ratio, serum amylase activity,pancreatic levels of TNF-α and IL-6, degree of lipid peroxidation, reduced glutathione levels, NF-κB binding activity, pancreatic and lung myeloperoxidase activity) and morphological parameters of the disease were improved before and after treatment with the PN50 *** to the histological findings, PN50 protected the animals against acute pancreatitis by favoring the induction of apoptotic, as opposed to necrotic acinar cell death associated with severe acute ***: Our study implies that reversible inhibitors of stress-responsive transcription factors like NF-κB might be clinically useful for the suppression of the severity of acute pancreatitis.

Mineralized tissues are usually constructed of nanosized materials with ordered hierarchical structures. The main reason for their high load-bearing ability is the multi-scale hierarchy. It is important to have a method for measuring the energy absorbed during the nanoscale deformation of mineralized tissues. The objective of this study was to use a combination of nanoindentation and elastic-plastic mechanics techniques to measure the damage resistance of peritubular and intertubular dentin, based on the energy consumed in the plastic deformation regime and the volume created by the indents. The control materials were soda-lime glass, gold, and poly-methyl methacrylate (PMMA). Plastic deformation energy was calculated from the plastic part of load-displacement curves. The mean values of peritubular dentin and intertubular dentin were 3.8 × 109, and 5.2 × 109 j/m3, respectively, compared to glass, PMMA, and gold which were 3.3 × 107, 1.3 × 109, and 3.1 × 109 j/m3, respectively. This method can be applied to study the resistance of mineralized tissues or organic/inorganic hybrid materials to deformation at the nanoscale.
