Motor neurons are highly polarized cells,with long axons that extend to more than 1 m in the adult human.The axons further arborize into a specialized synaptic compartment,the motor unit,containing up to 2000 neuromuscular junctions(NMJs).While the size of other neuronal synapses can be up to 1μm,the NMJ is much larger and can reach 10–30μm(Jones et al.,2017).The vast size of the motor unit requires motor neurons to evolutionally adapt and supply this distal portion with a sufficient amount of ATP,as well as to replenish the axonal protein pool in order to maintain their synapses. 展开更多

This study explores the aesthetic dimensions of Kwame Nkrumah's cultural policies in the creation of Ghana's Presidential Seats and the State Sword. The study is an Art Historical research situated within the qualitative research paradigm. It had a population of a defmed class of cultural policy makers, art historians, traditional rulers, nationalists, visual artists and Ghanaians resident both in and outside Ghana. The study examined how the creation of Ghana's Presidential Seats and the State Sword were influenced by Kwame Nkrumah's cultural policies and the cultural significance of the aesthetic interplay of ethnic insignias used in capturing the Ghanaian concept of Political authority. The study revealed that, Nkrumah recognised the cultural art forms and elements of ethnic Ghana as assets for national development. In line with his policy of building the Nation State of Ghana, he used ethnic cultural art forms and elements. At independence, Nkrumah commissioned some visual artist to create some artistic pieces (politico-cultural artefacts) for the Ghanaian political authority with inspiration or based on what pertains in the traditional authority (Chieftaincy) of Ghana. Politico-cultural artefacts as used in this study refer to the artefacts produced based on the cultural concepts of the ethnic states for the use of the political authority of the Republic of Ghana. Among these artistic pieces are the three Presidential Seats, The State Sword, The President's Personal Standard Pole and the State Mace. 展开更多

Over 10%of English Restoration drama engaged its audience through plays that were translated from or imitated the Spanish capa y espada form of theatre.English plays modeled on this form used Spanish locations and a constructed and rigid idea of honor as a proxy for English society.While dialogue was still important,it performed physical action of this form,including frequent use of breeches roles and female characters sword fighting,allowed for different and effective critiques and models of social behavior for women in England.Particularly important were concerns about women’s behavior and status in English society,and the presence of the actress for the first time on English stages heightened the effectiveness of these plays as an instrument of social discussion. 展开更多

Objective: to explore the clinical application of open-throat sword spray in the treatment of children with acute pharyngitis and acute suppurative tonsillitis is significant or not. Methods: 50 children with acute pharyngitis and acute suppurative tonsillitis treated in pediatrics of our hospital from June 2020 to January 2021 were divided into groups according to the order of admission for diagnosis and treatment. The groups were named control group and experimental group, with 25 patients in each group. The control group was given routine nursing mode in 25 cases, and the remaining 25 cases were automatically incorporated into the experimental group and were treated with open-throat sword spray treatment. The treatment lasted for 15 days. After the end of the treatment, full-time nurses were responsible for recording the clinical efficacy, blood picture index and adverse reactions of the two groups in detail. Results: the clinical efficacy, blood index and the incidence of adverse reactions were compared between the two groups. The total effective rate, c-reactive protein, neutrophil level, white blood cell count and the incidence of adverse reactions were significantly different between the two groups. The total effective rate, c-reactive protein, neutrophil level and white blood cell count in experimental group were significantly better than those in control group, and the incidence of adverse reactions in experimental group was significantly lower than that in control group (P < 0.05). Conclusion: in the clinical treatment of children with acute pharyngitis and acute suppurative tonsillitis, taking open throat spray can achieve significant clinical curative effect, significantly better than conventional western medicine treatment, not only reduces the incidence of adverse reactions, but also improves the clinical symptoms of children, it is the ideal treatment plan for children with acute pharyngitis and acute suppurative tonsillitis. 展开更多

This sword was a popular weapon with warriors in ancient China, but it was also worn by gentlemen as status symbol. It was first used at the end of the Shang Dynasty (21st Century B.C.-16th Century B.C.) and became popular during the Spring and Autumn period (770 B.C.-476 B.C.) and the Warring States period (475 B.C.-221 B.C. ). The best examples of this sword at that time were made in the Wu State and the Yue State. The sword was used by Gou Jian, King of the Yue State during the Warring States period.
