AIM：To analyze the visual outcomes and the posterior capsule opacification（PCO）with the new Incise？MJ14intraocular lens（IOL）implanted through a 1.4 mm clear corneal incision（CCI）in patients who underwent bimanual microincision cataract surgery（B-MICS）.METHODS：Eighty eyes which underwent cataract surgery using B-MICS technique performed by the same experienced surgeon were included in the study：40 eyes were implanted with an Incise？MJ14 IOL through a 1.4 mm CCI（group A）without enlargement of the main CCI,while 40 eyes were implanted with an Akreos？MI60 IOL with enlargement of the main CCI to 1.8 mm（group B）.Best corrected visual acuity（BCVA）,astigmatism and endothelial cell loss were evaluated before and after surgery at 7,30d and *** segment-optical coherence tomography（AS-OCT）of CCI was performed at 1,3,7,30d,6 and *** incidence was evaluated at 18mo using EPCO 2000 ***：Mean BCVA improvement and endothelial cell loss were statistically significant at 18mo in both groups with no difference between the two groups;no statistically significant difference in surgically induced astigmatism（SIA）was noticed in the two *** AS-OCT the only significant alterations in the CCI were endothelial gaping and local detachment of Descemet’s membrane at 1 and 7d after surgery;no statistically significant alterations were found at 1,6 and *** score at 18mo was 0.03±0.07for group A and 0.08±0.18 for group B（P=0.11）with no sign of central optic plate invasion in both ***：The implant of the new Incise？MJ14 IOL through a 1.4 mm CCI and B-MICS technique appeared to be a safe and effective procedure with rapid visual *** rate resulted very low and the CCI presented few morphological alterations which were only detectable in the first days postoperatively and achieved fast corneal healing during the long-term follow-up.

Axonal tuning by GABA_(A) receptor unveils novel tricks from an old dog

In the last years,axonal conductance of action potential trains became a novel subject of study,changing the view of axons,from a static cable-like compartment to a more complex and dynamic system(Debanne et al.,2011).Axonal computation,indeed,is canonically constituted by the action of voltage-gated ion channels,such as the classic Na+and K+channels,but recent studies demonstrated that it can be modulated by the action of other ion channel pumps,and metabolic factors(Byczkowicz et al.,2019;Zang and Marder.

Surrogate potency assays:Comparison of binding profiles complements dose response curves for unambiguous assessment of relative potencies

引用

Journal of Pharmaceutical Analysis 2018年第2期8卷 138-146页

作者： Robert Karlsson veronica Fridh Asa Frostell Purification and Analysis GE Healthcare Life SciencesUppsalaSweden

Surface plasmon resonance(SPR) systems are widely used for detailed characterization of antibody activities including antigen and Fc-receptor binding. During the later stages of development, where the focus is to ensure that established critical quality attributes(CQAs) are maintained during cell culture,purification and formulation processes, analysis is simplified, and relative potencies are often determined. Here, simulation of binding data revealed that relative potency values, determined via parallel line analysis(PLA) and half maximal effective concentration(EC50) analysis accurately reflect changes in active concentration only if binding kinetics remain unchanged. Changes in the association rate constant shifted dose response curves, and therefore relative potencies, in the same way as changes in analyte concentration do. However, for interactions characterized by stable binding, changes in the dissociation rate constant did not result in any shift, suggesting that this type of change may go unnoticed in the dose response curve. Thus, EC50 and PLA analyses of dose response curves obtained with an anti-TNF-α antibody were complemented with the Biacore functionality for sensorgram comparison analysis, whereby changes in antigen and Fc-receptor binding profiles could be detected. Next, analysis of temperature stressed TNF-α antibody revealed that calibration free concentration analysis(CFCA) data correlated perfectly with relative potency values. Together, these results demonstrate that combinations of SPR based dose response curves, sensorgram comparison and CFCA can be used to strengthen the confidence in relative potency assessments, and suggest that SPR can potentially be used as a surrogate potency assay in the quality control of biotherapeutic medicines.

Interactions between Axillary Branches of Arabidopsis

Molecular Plant 2008年第2期1卷 388-400页

Studies of apical dominance have benefited greatly from two-branch assays in pea and bean, in which the shoot system is trimmed back to leave only two active cotyledonary axillary branches. In these two-branch shoots, a large body of evidence shows that one actively growing branch is able to inhibit the growth of the other, prompting studies on the nature of the inhibitory signals, which are still poorly understood. Here, we describe the establishment of two-branch assays in Arabidopsis, using consecutive branches on the bolting stem. As with the classical studies in pea and bean, these consecutive branches are able to inhibit one another＇s growth. Not only can the upper branch inhibit the lower branch, but also the lower branch can inhibit the upper branch, illustrating the bi-directional action of the inhibitory signals. Using mutants, we show that the inhibition is partially dependent on the MAX pathway and that while the inhibition is clearly transmitted across the stem from the active to the inhibited branch, the vascular connectivity of the two branches is weak, and the MAX pathway is capable of acting unilaterally in the stem.

Micromechanical adaptation as a treatment for spinal cord injury

引用

Neural Regeneration Research 2019年第11期14卷 1909-1911页

作者： veronica estrada Hans werner Müller Molecular Neurobiology Laboratory Department of Neurology Heinrich-Heine-University Medical Center Düsseldorf

Spinal cord injury: Thus far injury of the spinal cord is incurable and, in the majority of cases, a devastating and life-changing event. The worldwide incidence rate of spinal cord injury (SCI) ranges from 250,000 to 900,000 (***, 2013;Kumar et al., 2018) new cases per year. SCI outcome includes the damage of axons, demyelination of axons, loss of signal transduction, and consequential long-lasting motor and sensory deficits. Additionally, the non-use of muscles can lead to atrophy and joint contractures, thereby further reducing the possibility of recovery. Depending on the spinal level and the severity of the injury, the extent of the damage can vary and spontaneous recovery is possible to varying degrees.

Challenges and perspectives on high and intermediate-temperature sodium batteries

引用

Nano Research 2017年第12期10卷 4082-4114页

Energy storage systems are selected depending on factors such as storage capacity, available power, discharge time, self-discharge, efficiency, or durability. Additional parameters to be considered are safety, cost, feasibility, and environmental aspects. Sodium-based batteries （Na-S, NaNiC12） typically require operation temperatures of 300-350 ~C. The high operating temperatures substantially increase the operating costs and raise safety issues. This updated review describes the state-of-the-art materials for high-temperature sodium batteries and the trends towards the development and optimization of intermediate and low-temperature devices. Recent advances in inorganic solid electrolytes, glass-ceramic electrolytes, and polymer solid electrolytes are of immense importance in all-solid-state sodium batteries. Systems such as Na~ super ionic conductor （NASICON, Nal^xZr2PB-~SixOl2 （0 -〈 x _〈 3））, glass-ceramic 94Na3PS4＂6Na4SiS4, and polyethylene oxide （PEO）-sodium triflate （NaCF3SO3） are also discussed. Room temperature ionic liquids （RTILs） are also included as novel electrolyte solvents. This update discusses the progress of on-going strategies to enhance the conductivity, optimize the electrolyte/electrode interface, and improve the cell design of emerging technologies. This work aims to cover the recent advances in electrode and electrolyte materials for sodium- sulfur and sodium-metal-halide （zeolite battery research Africa project （ZEBRA）） batteries for use at high and intermediate temperatures.
