Effects of detraining after blood flow-restricted low-load elastic band training on muscle size and arterial stiffness in older women

Background: We examined the effects of detraining after blood flow-restricted (BFR) low-load elastic band training on muscle size and arterial stiffness in older women.Findings: Fourteen women were divided into BFR training (BFR-T) or non-BFR training (CON-T). Each group participated in 12 weeks of arm curl and press down training using an elastic band either with (BFR-T) or without BFR (CON-T). Muscle cross-sectional area (CSA) and maximum voluntary isometric contraction (MVIC) for upper arms and cardio-ankle vascular index (CAVI) were evaluated before and after the 12-week training period and also after 12 weeks of detraining. CSA and MVIC were higher at post and detraining (CSA: 16.3% (p 0.05) for elbow extension; MVIC: 7.3 and 3.9% (both p > 0.05) for elbow flexion and 17.6 and 15.1% (both p < 0.01) for elbow extension) than at pre for the BFR-T, but not for the CON-T. There was no change in CAVI for the two groups.Conclusions: Increased muscle strength/size following 12 weeks of elastic band BFR-T was well maintained with a low risk of arterial stiffness after 12 weeks of detraining in older women

Study on the Teaching Strategy of an Elementary School and Improving the Program for Training Students to be Teachers of University (2) :In the Case of Social Studies, Music, Physical Education and Information Ethics Education

　本研究は，教科内容構成の考え方に基づいて小学校の授業づくりのあり方を検討するとともに，それをふまえることで大学の教員養成プログラムの授業が具体的にどのように改善されるかを明らかにしようとしたものである。教科内容構成とは，教員養成において従来から課題とされてきた教科の内容に関わる知識・技能と教科の指導法に関わる知識・技能の分離という問題を克服するために提案されたものである。教科内容構成は，教科の内容と指導法に関わる知識・技能を統合し，それらを応用して，教師が自ら「どのような内容をどのように教えるべきか」を考え，授業づくりに取り組むことができるようになるための考え方を示すものであり，本研究では教員養成プログラムにおける具体的な授業プランを提示してそれを明らかにしていく。本稿では，特に，小学校の社会科，音楽科，体育科，情報モラル教育を事例として論じていくことにしたい

Voltage-gated sodium channel expressed in cultured human smooth muscle cells: involvement of SCN9A

AbstractVoltage-gated Na+ channel (INa) is expressed under culture conditions in human smooth muscle cells (hSMCs) such as coronary myocytes. The aim of this study is to clarify the physiological, pharmacological and molecular characteristics of INa expressed in cultured hSMCs obtained from bronchus, main pulmonary and coronary artery. INa, was recorded in these hSMCs and inhibited by tetrodotoxin (TTX) with an IC50 value of approximately 10 nM. Reverse transcriptase/polymerase chain reaction (RT-PCR) analysis of mRNA showed the prominent expression of transcripts for SCN9A, which was consistent with the results of real-time quantitative RT-PCR. These results provide novel evidence that TTX-sensitive Na+ channel expressed in cultured hSMCs is mainly composed of Nav1.7
