发信号

Since the motherboard with the soft, hard disk, such as the use of DMA operations between the peripheral, DMA operation of the response process is as follows (AST386 in the floppy disk to DMA as an example): floppy disk drive made by DREQ2 signal to the DMA controller (82C206), and DMA controller to the CPU (80386) issued HRQ signal, CPU end the current bus cycle after HLDA response signal to the DMA controller, DMA controller issued a final response signal DMA to the floppy disk drive DACK2 allow its data into the system bus.

由于主板与软、硬盘等外设之间采用DMA操作，DMA操作的应答过程如下(以AST386中软盘DMA为例)：先由软盘驱动器发DREQ2信号给DMA控制器(82C206)，然后DMA控制器向CPU(80386)发HRQ信号，CPU结束当前总线周期后发响应信号HLDA给DMA控制器，最后DMA控制器发DMA响应信号DACK2给软盘驱动器允许其数据进入系统总线。

Results: MRI features of primary malignant lymphoma were as follows:① single or multiple lesions, mostly in supratentorial region;② round or irregular in shape, hypointense on T1WI, hypointense or isointense on T2WI with homogenous signal;③ mild edema around the lesion with mild space occupying effect;④ remarkab1e enhancement of the lesion;⑤ involvement of leptomeninges and/or dissemination via ventricular ependyma;⑥ sensitive to chemotherapy and radiotherapy. Size and shape changed remarkedly after treatment.

结果：脑内淋巴瘤MRI表现为：①种瘤单发或多发，以幕上分布为主；②形态圆形或不规则形，T1WI呈低信号，T2WI以高信号为主，信号不均匀；③瘤周水肿及占位效应较轻；④增强扫描肿瘤明显不均匀强化；⑤可侵及软脑膜、室管膜并沿之播散；⑥肿瘤对放疗和化疗敏感；形态、大小变化明显。

In the patient suspected of having acute hemorrhage, long TR, long TE images are critical for demonstration of the overall extent of the lesion, including those regions adjacent to the hemorrhage which are abnormally bright because of infarction, neoplasia, gliosis, other primary pathology or secondary acute edema.

Signal peptide sequence was removed lest it couldnt be recognized by Bacillus subtilis, gene coding for mature peptide was ligated to downstream of sacB signal peptide sequence of pWB980 to form a new ORF and generate pWB980-LipA, gene coding for its chaperone was also amplified and ligated to the downstream of LipA to generate a secretion/expression vector pWB980-LipAB.thechaperone gene was sequenced and analyzed by multiple alignments, resulted showed that there were mutations of nucleotides(1～7) and amino acids (1～2) with the other reported genes.

为了防止枯草芽孢杆菌信号肽酶不能识别脂肪酶的信号肽，切除掉脂肪酶的信号肽编码序列，与枯草芽孢杆菌分泌表达质粒pWB980连接并与质粒上的SacB信号肽构成一个完整的开放式阅读框，获得重组质粒pWB980-LipA，因为该脂肪酶的活性表达需要一个特异性分子伴侣帮助折叠成有活性的构象，将脂肪酶分子伴侣基因串连到脂肪酶基因的下游，获得重组分泌表达载体pWB980-LipAB并且测序分析分子伴侣的基因序列和氨基酸序列并与其它报导的序列进行了比对，发现有1到7个碱基的差异和1到2个氨基酸残基的突变。

Because both insulin and leptin levels are low in this type of diabetes, the long-recognized syndrome of 'diabetic hyperphagia'27 could potentially result from reduced CNS signalling by insulin, leptin, or by both hormones.

由于胰岛素和leptin水平是低在糖尿病的这个类型，长被认出的综合症状'糖尿病hyperphagia' 27可能潜在地起因于发信号由胰岛素， leptin，或者由两激素的减少的CNS。
