The effects of T- (-[-(-benzylpiperidin--yl)ethyl]-,-dihydro--methoxy--pyrrolo[,-]quinolin--one hemifumarate), a new quinoline derivative, on acetylcholinesterase (AChE) activity and acetylcholine (ACh) release were compared with those of the well-known cholinesterase inhibitors tacrine and 2020. T-, tacrine and 2020 all concentration-dependently inhibited AChE in rat brain homogenate (IC_50s = 109., 84. and 11. nM, respectively). In addition, although tacrine strongly inhibited butyrylcholinesterase (BuChE), T- and 2020 showed only weak activity on BuChE in human plasma. In ex vivo experiments, intraperitoneal administration of T- at a dose of 30 mg/kg inhibited AChE activity in the hippocampus, frontal cortex and parietal cortex of rats. The effect of T- on the extracellular ACh concentration in rat brain was measured using in vivo microdialysis. T- at doses of 10 and 30 mg/kg, i.p. increased the extracellular ACh concentration in the hippocampus and striatum in a dose-dependent manner. These findings suggest that T- activates the central cholinergic system by selectively inhibiting AChE activity, while weakly affecting peripheral BuChE activity, and that T- increases the extracellular ACh concentration in the brain, which is followed by inhibited AChE activity.

[Purpose] This study investigated the therapeutic effects of augmented reality (AR)-based EMG-triggered functional electric stimulation (FES) on stroke patients receiving rehabilitation. [Methods] Ten subjects who were in the chronic phase following stroke were divided into two groups for: ankle dorsiflexion with AR-based EMG-triggered FES (Experimental group, n=5), and EMG-triggered FES alone (Control group, n=5). Experimental subjects received ankle dorsiflexion with AR-based EMG-triggered FES for 20 minutes per day, 5 times per week over a week period. Muscle activation, ankle range of motion and muscle strength were measured to identify the effect of the AR training environment with EMG-triggered FES. [Results] The muscle activation of the medial and lateral gastrocnemius (GCM), as measured by EMG, the improvement was increased significantly after the intervention compared to before within the experimental groups of the tibialis anterior(TA), and the improvement was significantly greater in the experimental group than in the control group. Muscle strength of the tibialis anterior (TA) and GCM in dorsiflexion and plantarflexion were significantly greater post-intervention in the experimental group. [Conclusion] The results of this study provide evidence in support of incorporating an AR environment into ankle dorsiflexion training with FES for the improvement of muscle activity, and strength of chronic phase stroke patients.

L'entree en Iran des armees britannique et sovietique s'est produite en aout 1941. Elle ebranla du coup le regime de la dynastie pahlavi qui etait au pouvoir depuis 16 ans, et mena le pays vers l'instabilite politique et le chaos social. La defaite de l'arme gouvernementale, qui etait le pivot du regime de Reza Shah, reduisit considerablement le controle du gouvernement central dans le pays. Cette situation politico-sociale confuse permit le developpement de differents mouvements politiques en Iran. C'est ainsi que le 16 aout 1942 le parti clandestin Komeley Jiyanewey Kurdistan (J-K) est ne a Mehabad, une ville au nord-ouest de l' Iran. Des sa formation, ce parti a su etendre sa sphere d'activite et, en une courte periode de temps, a fini par mettre sous son influence la ville et ses alentours. A la fin de la Seconde Guerre mondiale, en ete 1945, le J-K etait devenu une organisation representant le mouvement nationaliste kurde en Iran. C'est a ce moment-la qu'un autre parti politique, le Hizbi Dimokratiki Kurdistan (HDK), fonde par Qazi Mihemed a Mehabad aussi, devait remplacer le J-K. Des le janvier 1946, le HDK proclama l'instauration de la≪Republique de Kurdistan≫. Cependant, les troupes sovietiques qui avaient pris sous leur protection la Republique evacuerent les terres iraniennes, en mai 1946. Six mois plus tard, sous la pression militaire du gouvernement central iranien, la republique s'ecroula. Deux theories tentent d'expliquer le passage du J-K au HDK. William Eagleton Jr., par exemple, affirme dans The Kurdish Republic of 1946 que le HDK a ete cree sur le conseil des autorites sovietiques. L'ex-secretaire general du Parti Democratique du Kurdistan d'Iran, 'Ebd el-Rehman Qasimlu maintient par contre que Qazi Mihemed a etabli le nouveau parti de sa propre initiative, eu regard a la situation politique de cette epoque-la. Il considere que la passage du J-K au HDK comme etant l'evolution d'un parti nationaliste clandestin en un parti democratique. En analysant ces deux theories et en se basant sur les autobiographies des personages qui se sont engages dans cet evenement, cette etude tentera d'examiner le principe directeur et les activites du J-K et de mieux comprendre les raisons pour lesquelles le J-K devait etre remplace par le HDK. La conclusion generale portera sur les differents objectifs politiques du J-K et du HDK. Le J-K visait l'elevation du niveau culturel du peuple tout en luttant contre le tribalisme, qui etait, selon lui, le probleme majeur de≪la nation kurde≫, et cela en ecartant toute idee de revolte militaire. Le J-K a aussi exclu de son cadre les elites sociales telles que les leaders des tribus et dirigeants religieux de peur qu'ils n'excercent une influence sur les membres du parti. L'automne de 1944 fut le debut d'une nouvelle ere pour le mouvement kurde. Alors que l'espoir de l'autodetermination augmentait parmi le peuple a mesure que s'approchait la fin de la guerre, la necessite de la force militaire a commence a se faire sentir dans le J-K. C'est pour cela que s'est produite au sein du parti une tendance a compter sur l'aide militaire des sovietiques et a recourir au leadership de Qazi Mihemed, qui avait une certaine influence meme sur les leaders tribaux. Mais cette tendance etait essentiellement incompatible avec la ligne fondamentale du J-K et, graduellement, a prive ce parti de sa raison d'etre. Ainsi, le HDK se substitua au J-K en tant que≪parti democratique≫visant a rallier d'abord les elites sociales sous sa banniere, en s'appuyant sur l'autorite personnelle de Qazi Mihemed.

長期的に見ると、景気のトレンドが低下し、在庫投資や設備投資の変動が小さくなっている。その背景には、経済のサービス化、グローバル化、DX、研究開発投資の拡大などの経済構造の変化がある。こうした中で、第 16 循環の山（2018 年 10 月）付近においては、景気動向指数（一致指数）と実質GDPの動きに乖離が見られたが、その要因としては、外需の減少ペースが景気を一気に冷え込ませるような急激なものではなかったことが大きい。加えて、労働市場では、人口減少下で女性や高齢者を中心に労働市場に参入する人が増え、雇用所得環境を下支えしていた。コロナショック後は、賃上げのモメンタムが強まっている。今後、労働市場の構造変化がどのように進むのか、それが景気循環にどのような影響を与えるのか、注視していく必要がある。 こうした景気循環の特徴の変化やその背景にある経済構造の変化を踏まえると、景気循環を適切に捉えるためには、第一に、景気循環の転換点を敏感に捉える必要があることに変わりはないが、一方で、第二に、生産に過度に重点を置かず、より幅広い指標を観察すること、第三に、経済の全体的な動向を捉えるという観点から、実質GDPの動向にも留意すること、が必要となろう。

Background

The differences in conditions of enteric-coated acid-labile drug release and absorption between healthy subjects in bioequivalence studies and gastrointestinal patients in clinical practice can lead to significant differences in gastric stability of original PPIs and generics. Thus, pathologic duodenogastric reflux (PDGR) and the pH increasing within PPIs administration still remain unaccounted for.

Methods

Two-stage modified comparative dissolution testing of original omeprazole (OO) and four generics (G

;;;) was performed. At first, we moved drugs from solution with pH . (.±0.05) to pH 7.0 (7.0±0.05) and measure concentration of omeprazole in solution by high-performance liquid chromatography. According to our self-developed formula, pH 7 exposure time of resistance to PDGR for omeprazole is minutes, i.. the active substance should not be released within minutes at pH 7. The exposure at the second stage was conducted with pH (.0±0.05), that imitated gastric pH after PPI administration. And then we also moved drugs to pH 7 with the subsequent measurement of omeprazole concentration.

Results

Omeprazole concentrations after

, 10, 15, 20, 30, 45, 60 minutes in pH 7 solution at the first stage were different for OO and generics. For OO, these values were ,7±0,7%; 41,±,0%; 62,±,0%; 79,5±,%; ,5±,%; 81,6±,%; 80,6±,%; for Generic - 0; 49,±,%; 88, ±,%; 90,±,7%; 88, ±,%; 87,±,0%; 85,±,%; for Generic - 0; 30,6±6,%; 66,7±,%; 76,±7,%; ,±5,%; 86,0±,7%; 84,6±,%: for Generic - 80,±,6%; ,5±,%; , ±,%; ,±,7%; 81,±,%; ,±,0%; ,0±,%; for Generic - ,5±,7%; 84,±0,%; 84,±,%; , ±0,%; ,±0,%; ,±0,%; ,±,%, respectively.

An analysis of the omeprazole concentration in pH 7 solution at the second stage revealed the following parameters after the same time: for OO -

,±0,6%; 40, 5±,0%; 62,±,0%; 80,0±,%; 85,±,%; ,±,%; 80,±,5%; for Generic - 0; 67,0±7,%; 89,7±,%; 91, ±,%; 89,±,6%; 88,±,%; 87,±,%; for Generic - 0; 42,±5,6%; 75,±7,%; 81,0±6,0%; 88,±,%; 88, 6±,%; 87,±,0%; for Generic - 85,5±0,5%; 85,6±0,5%; 84,7±0,%; ,7±,0%; 84,±0,%; 84,±0,%; 84,±0,%, respectively. Generic release and degradation were completely realized at pH .

Conclusion

Decreased gastric stability of Generic

and Generic makes PDGR and inhibited gastric acid secretion due to PPIs administration the potential causes of decreased enteric-coated acid-labile drugs stability.

BCR-ABL

International Scale（IS）測定はチロシンキナーゼ阻害剤で治療されている慢性骨髄性白血病（CML）患者の治療効果をモニターする上で重要な検査法である。稀ではあるが，BCR-ABL IS測定ができないCMLが存在することが知られている。本研究において，我々は，そのようなBCR-ABL IS測定のできないCML患者を経験し，分子生物学的な方法で，その原因を解明した。本例ではABL遺伝子における切断点がaエクソン内にあることが分かり，そのことがABLのaエクソンを欠いた14a（a）キメラ遺伝子のmRNAのみの発現を誘導していた。aエクソンは本邦における検査部でのIS測定において重要な要素であり，これが欠損することが測定不能の原因であった。このようなIS測定ができない稀なCML症例をさらに集積して，その分子構造を解明することが待たれる。

The association between apolipoprotein (Apo-) polymorphism and the response of plasma cholesterol to dietary therapy (cholesterol intake of less than 300mg/day) was investigated for about weeks in 208 nonfamilial hypercholesterolemia patients (/ 161, / 47). The baseline lipoprotein concentration and the intake of energy and lipids were not significantly different between subjects with / and those with / phenotypes. After the dietary therapy plasma total cholesterol and low density lipoprotein cholesterol were significantly decreased in both phenotype groups (p<0.05). The patients with / had significantly smaller reductions of LDL-C than the patients with /. The changes of LDL-C showed a significant difference between the patients with / and / by the Kruskal Wallis test (p=0.041). The presence of / predicted the degree of cholesterol reduction following dietary therapy.

. The chromosome numbers of 64 species have been studied on which 56 are investigated for the first time.
. Morphological, anatomical and cytological findings on the Musaceae in the broad sense are considered from a phylogenetical standpoint and three distinct groups:
a) Musa-Ensete, ) Ravenala-Strelitzia-Phenakospermum and c) Holiconia are recognised as suggested by some authors. For these groups sub-familial status is proposed.
. Lowiaceae have been studied for the first time cytologically and their chromosome morphology, distinct from that of any other group of Zingiberales, confirms their claim to familial status.
. Consideration of the conflicting theories proposed to account for the higher chromosome number in genera like Globba, Alpinia, and Phaemeria, etc. leads to rejection of Chakravorti's hypothesis of wholesale fragmentation of chromosomes and the acceptance of the opposed view of Raghavan and Venkatasubban and others.
5. Holttum's transference of the genus Zingiber to the tribe Hedychieae has been given cytological support on the following points:
a) the basic number in the genus Zingiber correlates with that of Kaempferia.
) the new tribe Alpinieae (which is infact Zingibereae without Zingiber) have consistently 48 chromosomes in their somatic complements.
6. It is suggested that the African representatives of Kaempferia should be given the status of genus; Cienkowskya on the following points:
a) the difference in floral morphology
) geographical separateness and
c) the difference in the number and morphology of the chromosomes. By comparing the present and past findings, various lines of evolution of the chromosome complements within each group are discussed.
7. The basic number 11 is considered to be probably the original one for the Zingiberales as a whole, being present in Ravenala which is the most primitive member in the order. From this secondary basic numbers have arisen through evolution.

The bearing capacity of plane strain model footings on sand is numerically investigated with a finite element method and a polar hypoplastic constitutive law. The constitutive law is obtained through an extension of a non-polar hypoplastic constitutive law by polar quantities : rotations, curvatures, couple stresses and a characteristic length. It can reproduce the salient features of granular bodies while taking into account shear localisation. The hypoplastic constants are calibrated with element test calculations on the basis of plane strain and triaxial compression tests. The FE-analyses are performed for both different mean grain diameters and initial densities of dry medium sand, and footing widths. The effect of material constants on the load-displacement curve is also investigated. The FE-results are compared with model tests. Advantages and limitations of a polar hypoplastic approach are outlined.
