During faunal studies of psammophilic ciliates along the coast of Qingdao, China, several marine karyorelictean species were isolated. Among them,four species within the genus Remanella were investigated, including two species new to science:i.e., R. rugosa, Remanella elongata sp. nov.,Remanella aposinica sp. nov.,and ***. Remanella rugosa has been reported several times, but this study is the first to provide detailed morphological characters and phylogenetics. Remanella elongata sp. nov. can be distinguished from its congeners by the presence of complex cortical granules, fewer macronuclei, and longer body size. Remanella aposinica sp. *** from its congeners by having 14–17 right lateral ciliary rows and 24–37 dikinetids of intrabuccal kinety. Poorly known Remanella rugosa var. unicorpusculata(Kahl, 1933) Foissner, 1996should be elevated from subspecies to species level,Remanella unicorpusculata(Foissner, 1996) ***., based on detailed redescriptions with statistical data, living morphology, infraciliature, and species definitions. Small subunit(SSU) rDNA was sequenced for the four species, and phylogenetic analysis revealed that all known taxa in Remanella formed the outline branch to the genus Loxodes with moderate to high bootstrap support among Remanella lineages.

Intrathecal administration of resiniferatoxin produces analgesia against prostatodynia in rats

Chinese Medical Journal 2007年第18期120卷 1616-1621页

Background Prostatodynia remains a difficult clinical problem. Resiniferatoxin （RTX）, an ultrapotent vanilloid, can produce a selective and long-lasting desensitization of nociception via C-fiber sensory neurons. Substance P （SP） and calcitonin gene-related peptide （CGRP） released from C-fibers are key neurotransmitters in visceral pain. In this study, we evaluated the analgesic effect of intrathecal RTX on rat prostatodynia. Methods Male Sprague-Dawley rats were divided into 3 groups for different treatment. In group A, sham operation was preformed. In group B, 100 μl complete Freund＇s adjuvant （CFA） was injected into the rat＇s bilateral ventral prostate to induce chronic inflammation. In group C, after prostatitis formed, 50 μl 10 nmol/L RTX was injected into the rat＇s lumbosacral （L5-S2） vertebral canal. SP and CGRP contents in the spinal cord were investigated by immunohistochemistry and radioimmunoassay （RIA）. Their transcriptional levels in dorsal root ganglion （DRG） were determined by reverse transcriptase polymerase chain reaction （RT-PCR）. In addition, pelvic nerve afferent discharge was recorded to explore the neuro-electrophysiological mechanisms underlying RTX-induced effect. Results SP and CGRP released in the spinal cord and their synthesis in DRG were increased significantly in response to CFA-induced chronic prostatitis, whereas this increase was effectively inhibited by intrathecal RTX. Meanwhile, pelvic nerve afferent electrical activity was enhanced significantly in rats with chronic prostatitis, but it was attenuated markedly in RTX-treated rats paralleled by the change of neuropeptides. Conclusions Intrathecal RTX administration could produce an analgesic effect on rat prostatodynia. Suppression of pelvic nerve afferent electrical activity may be a crucial mechanism underlying RTX-induced analgesia. RTX intrathecal application may present a novel analgesic strategy of prostatodynia.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

与传统城镇相比,特色小镇除了注重生产功能之外,更注重生活功能,它追求特色化或主题化发展,追求产业中高端化、人口素质中高端化、生活品质化、生态环境景观化,兼具生产、生活、生态、休闲、文化五大功能。特色小镇主要是因为特定的生产集聚和生活集聚而产生的。它的出现可以追溯到古代,但只有当城市化率达到一定的水平,人类进入到工业化后期和逆城市化之后,特色小镇才会规模化出现。特色小镇是逆城市化过程中城市人口流出的蓄水池,后工业社会产业转移与升级的第二空间,旅居时代人们精神生活的家园。在我国特色小镇是小城镇建设和重点镇建设的升级版,是中国新型城镇化的重要路径选择,也是中小城镇未来发展的重要方向。
