Apart from the clear effects on crop growth and grain yield, limiting availability of S has been shown to favour the synthesis and accumulation of S-poor or low-S storage proteins such as ω-gliadin and high molecular weight subunits of glutenin at the expense of S-rich proteins. These changes in protein composition are associated with alterations of dough rheology. Significant responses of breadmaking quality to the addition of S fertilisers have been observed under field conditions.

Expanded MSCs were induced to differentiate into nerve cells withthree different treatment protocol in the prensent study . On the following day, the medium was replaced with preinduction medium consisting of DMEM, 20% FCS, and 10 ng/ml basic fibroblast growth factor. After 24 h, the preinduction medium was removed, the cells were washed twice with PBS, and neuronal induction medium containing DMEM supplemented with 2% DMSO and200 m bu-tylated hydroxyanisole was added. In later experiments, we used DMEM with 5 mM p - mercaptoethanol or sulfo - glycerine as an alternative neuronal induction medium for the same incubation.

将待诱导分化的MSCs按0.4x10~6／ml接种于事先放置有消毒盖玻片的六孔板内制备细胞爬片，分别采用三种不同的方法诱导第2代至10代的MSCs向神经细胞分化，即方法1先用含bFGF的培养基进行预诱导，之后再用含叔丁基对羟基茴香醚，和二甲亚砜的无血清培养基进行诱导；方法2和方法3用B-巯基乙醇和硫代甘油进行预诱导，然后不同浓度的上述物质进行正式诱导。

So long as Hector lived and Achilles nursed his anger, and so long as the city of Priam remained untaken, the great wall of the Achaeans stood firm; but when the bravest of the Trojans were no more, and many also of the Argives, though some were yet left alive when, moreover, the city was sacked in the tenth year, and the Argives had gone back with their ships to their own country- then Neptune and Apollo took counsel to destroy the wall, and they turned on to it the streams of all the rivers from Mount Ida into the sea, Rhesus, Heptaporus, Caresus, Rhodius, Grenicus, Aesopus, and goodly Scamander, with Simois, where many a shield and helm had fallen, and many a hero of the race of demigods had bitten the dust.

只要赫克托耳仍然活着，阿基硫斯怒气不消，只要王者普里阿摩斯的城堡不被攻陷，阿开亚人的高墙就能稳稳当当地站立。但是，当所有最勇敢的特洛伊人战死疆场，众多的阿耳吉维人长眠客乡，剩下一些人回返后，当普里阿摩斯的城堡在第十个年头里被阿耳吉维人捣毁，后者驾着海船回返他们热爱的故乡后，那时，波塞冬和阿波罗议定，引来滚滚的河水，冲袭扫荡，捣毁护墙。

The isolated cells are able to orient and migrate to the magnet in artificial magnetic field but could not orient swimming only under the geomagnetic field. Magnetosomes produced by Acidithiobacillus ferrooxidans were range from 40nm to 90 nm according to the results of TEM. Energy dispersive X-ray analysis indicated that extracted magnetic particles consisted of oxygen and iron. The results show that some Acidithiobacillus ferrooxidans cells have weak magnetotaxis and they could be able to be separated by solid-plate magnetophoresis method from others. With the development of this new isolation method, it is possible that we could do deeper research to generate a comprehensive description of the mechanism that how Acidithiobacillus ferrooxidans synthesize the magnetic particles.

实验结果表明，氧化亚铁硫杆菌具有较弱的趋磁性，在人工磁场下会进行趋磁运动，但仅在地磁场作用下不能定向运动，利用固体平板磁泳筛选纯化含有磁性颗粒的氧化亚铁硫杆菌的方法是切实可行的，磁泳分离技术的进一步完善和改进为传统的微生物菌种分离提供了新的途径，为研究纯氧化亚铁硫杆菌菌株胞内磁性颗粒的形成条件及机理提供了前提条件，也为今后从浸矿细菌中分离筛选更多的含有磁性颗粒的菌株打下基础。
