通过Box-Behnken设计对Pb^(2+)的生物吸附过程主要参数进行响应曲面分析优化.利用扫描电子显微镜、能量弥散X射线探测器以及傅里叶变换红外光谱,分析Pb^(2+)对生物质表面的生物吸附机理和特点.通过扫描电子显微镜和能量弥散X射线探测器可观察到Rhodotorula mucilaginosa生物质的形态和组成元素,显示生物吸附发生后存在铅离子.在初始条件下,Pb^(2+)的质量浓度为30 mg/L,pH为5.45,利用Design-Expert软件,通过响应面法得到响应面图,可以看出铅离子对生物质的最佳吸收值达到1.45 mg/g,吸收时间为25 min.二次型方差分析(ANOVA)证明该模型的相关性,其变异系数C.V.=2.4%,表明实验结果的准确性和可靠性.

The novel nano-sized powder of chemical formula CaCu3Ti(4-x)ErxO(12-δ) with x = 0, 0.02, 0.1 were synthesized by the sol-gel combustion method. The effect of Er doping on Ti sites in CaCu3Ti4O12 (CCTO) was examined. X-ray powder diffraction analysis confirmed the formation of the monophasic compounds and indicated the structure to be remaining cubic in Er doping. The dielectric characteristics of CaCu3Ti(4-x)ErxO(12-δ) were studied in the 100Hz-1 mHz frequency range at various temperatures (room temp to 500 °C). A remarkable grain size 1-2 μm was observed on Er substitution using HR-SEm. The dielectric constant of CaCu3Ti4O12 increased on Er doping. The frequency and temperature responses of dielectric constant of Er doped samples were found to be similar to that of CaCu3Ti4O12. Energy dispersive X-ray (EDX) diffraction pattern for the ceramics sintered at 950 °C in air for 3 h, confirmed the presence of Erbium. From these results, it is confirmed that Er doping is an efficient method to achieve a high dielectric constant and low loss.

Aim: To establish the reliability, efficacy, and safety of disposable prism tonometry and validate its routine use for screening as well as monitoring of glaucoma. methodology: Intraocular pressure (IOP) of 400 eyes of 200 consecutive patients who attended the general ophthalmic clinic was checked with both the Goldmann applanation tonometer and a disposable tonometer prism by an experienced examiner after obtaining informed consent. The data were statistically analysed. Results: The mean difference in the IOP between the two types of prismswas 0.1 mmHg (SD ± 1 mmHg). Conclusion: Disposable prism tonometry provides a reliable, effective, and safe alternative to Goldmann reusable prism tonometry for routine screening as well asmonitoring of glaucoma with the advantages of eliminating the need for chemical disinfection and therefore eliminating the risk of crossinfection.

We describe clinical, electrophysiological, histopathological and molecular features of a unique disease caused by mutations in the glycyl-tRNA synthetase (GARS) gene. Sixty patients from five multigenerational families have been evaluated. The disease is characterized by adolescent onset of weakness, and atrophy of thenar and first dorsal interosseus muscles progressing to involve foot and peroneal muscles in most but not all cases. mild to moderate sensory deficits develop in a minority of patients. Neurophysiologically confirmed chronic denervation in distal muscles with reduced compound motor action potentials were features consistent with both motor neuronal and axonal pathology. Sural nerve biopsy showed mild to moderate selective loss of small-and medium-sized myelinated and small unmyelinated axons, although sensory nerve action potentials were not significantly decreased. Based on the presence or absence of sensory changes, the disease phenotype was initially defined as distal spinal muscular atrophy type V (dSmA-V) in three families, Charcot-marie-Tooth disease type 2D (CmT2D) in a single family, and as either dSmA-V or CmT2D in patients of another large family. Linkage to chromosome 7p15 and the presence of disease-associated heterozygous GARS mutations have been identified in patients from each of the five studied families. We conclude that patients with GARS mutations present a clinical continu um of predominantly motor distal neuronopathy/axonopathy with mild to moderate s ensory involvement that varies between the families and between members of the s ame family. Awareness of these overlapping clinical phenotypes associated with m utations in GARS will facilitate identification of this disorder in additional f amilies and direct future research toward better understanding of its pathogenes is.
