Arac.noiditis ossific.ns is an intradural extramedullary lesion resulting from an unusual c.ronic.meningeal inflammatory proc.ss and it is thought to be the sequela of end-stage adhesive arac.noiditis sec.ndary to surgery, trauma, arac.noid hemorrhage, meningeal irritation, myelography (partic.larly oil-based c.ntrast agents), and spinal anesthesia. The spinal arac.noiditis ossific.ns may be silent or c.use a variety of symptoms depending on its loc.tion and unc.mmonly happen to c.use spinal c.rd c.mpression. Very little attention has been paid to the management and outc.me of this rare c.ndition in the neurosurgic.l reem. We report the c.se of a 45 years old man admitted with L1 - L2 arac.noiditis ossific.ns revealed by polyradic.lopathy on inc.mplete c.uda equina syndrome mimic.ing spinal c.nal tumors. The patient underwent surgery and we performed the laminec.omy of L1 - L2, total resec.ion of the lesion, followed by a c.mplete remission of the hemiparesis after three months of kinesitherapy nursing.

The NiFe2O4 inert anode is synthesized by high-temperature solid-state reac.ion method using NiO and Fe2O3 as main raw materials and adding MnO2 powder as additive. Arc.imedes method using water immersion tec.nique is used to measure the sintering performanc.s of sampies. The static.thermal c.rrosion rates of samples are measured by weight loss. SEM is employed for the observation of material mic.ostruc.ure, and phase struc.ure of the sample surfac. after c.rrosion is determined by XRD. The experimental results indic.te that a suitable MnO2 additive c.ntent is 2%, while the sintering performanc. is the best, and the static.thermal c.rrosion rate is the lowest. Bec.use of MnO2 dopant enric.ing at c.ystal boundary, the c.rrosion reac.ion of molten salt to c.ystal grain c.eates Mn2AlO4 phase, whic. is denser than NiFe2O4 phase, and prevents the c.yolite molten salt to penetrate into the inert anode, thus reduc.ng the c.rrosion.

实时直接分析质谱无需或者仅需简单的样品制备,即能对样品进行原位电离及直接快速的进样分析,已被广泛运用于食品、司法科学、药物分析、临床科学、环境等领域。尽管已有不少文献报道DART-MS的定量结果与液相/气相色谱-质谱相当,但其痕量分析物的检测性能仍是关键问题。为获得更准确的定量结果,研究人员开发出了一系列样品前处理技术与DART-MS联用。该文从DART-MS的原理出发,对其不同研究领域中无需样品前处理的应用进行了综述,并进一步介绍了样品预处理技术(如固相萃取、固相微萃取、顶空固相网增强吸附、分散固相萃取、分散磁性固相萃取、机械化学萃取、微波辅助萃取和热解吸)与DART-MS联用的研究成果。该综述旨在对DART-MS的样品直接分析的应用及样品前处理技术的开发提供帮助。

Amplitude modulation of near-wall turbulenc. by large-sc.le struc.ures in the outer layer is investigated by direc. numeric.l simulation of turbulent c.annel flows at Reynolds number Re= 540, 1000, 2000. The effec. of modulation is obvious in the two-point c.oss-sec.ion c.rrelation map, and the c.rrelation c.effic.ents inc.ease signific.ntly with the Reynolds number. The influenc. of modulation is reflec.ed in the tail of the probability density func.ion of the near-wall flow signals, whic. expands as the Reynolds number inc.eases. The flatness fac.or provides a quantitative desc.iption of the high fluc.uation events due to modulation. Vortic.l struc.ures assoc.ated with modulation are revealed by c.nditionally averaging the flow field of the near-wall extreme events, providing a depic.ion of how the influenc. of the large-sc.le struc.ures penetrate towards the near-wall region.

The nasopharyngeal swab for c.VID-19 testing is generally c.nsidered safe;however, it is primarily performed by staff that may not c.mpletely understand the anatomy of the nasal c.vity and nasopharynx. We report the treatment of a 48-year-old man who developed unilateral left rhinorrhea after a nasopharyngeal swab sample. It is aimed to draw attention to this c.mplic.tion that c.n be prevented with the appropriate tec.nique during nasopharyngeal swab sampling.

By implanting B+ and O+ ions respec.ively into polyc.rbonate (Pc. plates, the surfac. mec.anic.l properties of Pc.have been improved. Measurement by Nano Indenter II showed that the hardness of samples inc.eased 7-25 times than that before implantation; and the modulus of elastic.ty raised 2-5 times. The wear-resistanc. was tested by ball c.usher; the width and depth of the wear-streak dec.eased by 1/3-1/2 or even more. The struc.ure, deformation and appearanc. were analyzed by using Mic.o-FTIR Spec.ra, ESc. method and the steps instrument. These analyses showed that the struc.ure of Pc.had been modified: a series of new c.oss-linking yielded, it depends on the Linear Energy Transition (LET) of implanted ions in the high polymer c.mpounds.
