イネいもち病に有効な数種殺菌剤のいもち病菌の侵入に対する影響を, セロファン膜を用いて検討した. 植物細胞壁のモデルとして用いたセロファン膜上で, いもち病菌胞子は発芽し, 宿主上と同様に付着器から侵入糸によって膜内に侵入した (付着器侵入) が, 付着器を形成しないで侵入する (菌糸侵入) ものも観察された. このように異なった2種の侵入様式に対して同程度に阻止する薬剤もあったが, ある薬剤は菌糸侵入をまったく阻止せず, 付着器侵入を特異的に阻止した. この薬剤については, 胞子発芽, 付着器形成および菌糸生育のいずれに対しても影響のないことがすでに知られている. In vitro で検討された抗菌力のうち付着器侵入阻止力が, いずれの薬剤の場合にも, 葉鞘検定による結果と有効濃度の点でよく一致しており, 防除効果を説明しうるようであった.

Isoprothiolane (IPT), diisopropyl 1, 3-dithiolane-2-ylidenemalonate was tested for its effect on vegetative growth and infection process of Pyricularia oryzae Cav. Mycelial growth in a glucose-yeast extract liquid medium was inhibited completely at 20ppm, and partially at 10 and 5ppm. Abnormal hyphae like chlamydospore cells were frequently formed in the presence of IPT. IPT at 2ppm did not affect conidial germination and appressorium formation, but almost completely inhibited penetration when treated ...

Abstract Aims To investigate the efficacy and safety of insulin degludec/liraglutide (IDegLira) compared with its individual components in Japanese people with type 2 diabetes (T2D) uncontrolled on an oral antidiabetic drug (OAD). Materials and methods This 52‐week, open‐label, multicentre, treat‐to‐target trial randomized participants (n = 819) 1:1:1 to IDegLira, liraglutide 1.8 mg or degludec, as add‐on to their pre‐trial OAD. The maximum IDegLira dose was 50 dose steps (50 U degludec/1.8 mg liraglutide), ...

Tetrafluoromethane (CF4), the most stable perfluorocarbon, has a high global warming potential and high chemical stability. Various methods, including rotary kiln processing, plasma decomposition, and catalysts, are used to decompose CF4 before discharge to the atmosphere. However, these processes typically use a hydrolysis reaction to produce hydrogen fluoride (HF) and carbon dioxide, and the reactor needs to be made of specific materials to avoid corrosion from HF. In addition, adsorption or absorption ...

Multiple sclerosis (MS), a putative autoimmune disease of the central nervous system (CNS), commonly presents as relapsing-remitting MS (RRMS), characterized by recurrent episodes of peripheral disabling symptoms resulting from inflammatory CNS damage. Many RRMS patients transition to a chronic disease course with progressive neurological dysfunctions (secondary progressive MS, SPMS), with the progression rate varying between patients and over time. SPMS pathogenesis is now linked to immune-cell-mediated ...

The method of automatically controlling the CO2 concentration in a greenhouse depending on ventilation was examined in order to efficiently improve the productivity of strawberries under the weather conditions in the northern part of Kyushu in Japan. The effects of CO2 enrichment on the yields, fruit Brix, and economic value of the strawberry ‘Sagahonoka’ were investigated. In addition, in order to clarify the physiological response of ‘Sagahonoka’ to the CO2 concentration, the photosynthetic rate, ...

We present a new type of high speed range finder system that is based on the principle of triangulation range-finding. One of the unique elements of this system is a novel custom range sensor. This sensor consists of a 2D array of discrete photo-detectors. Each photo-detector is attached to an individual memory element. A slit-ray is used to illuminate the object which is then imaged by the sensor. The slit-ray is scanned at a constant angular velocity, so elapsed time is a direct function of the ...

Objectives: To examine the pre‐emptive analgesic effect of the non‐steroidal anti‐inflammatory drug zaltoprofen against rigid cystoscopy‐associated pain, and compare it with the effect of an anesthetic gel. Methods: Forty men periodically undergoing follow‐up office cystoscopy were enrolled in this prospective study. The effects of lidocaine gel alone or in combination with zaltoprofen, were examined. The following parameters were assessed using an 11‐point numerical rating scale: pain during injection ...

The ONO (oxide/nitride/oxide) inter-poly dielectric thickness scaling effect on electric-field-leakage-current characteristics and charge retention characteristics in nonvolatile memories are investigated. Surface top-oxide thickness strongly affects the charge leakage and retention characteristics. Thicker than 3 nm top oxide can block hole injunction from the anode. Thick top oxide can reduce leakage current in both high and low electric field regions. Moreover, it can improve charge retention ...

We introduce a new model for diagnosable systems called (t, k)-diagnosable system which guarantees that at least k faulty units (processors) in a system are detected provided that the number of faulty units does not exceed t. This system includes classical one-step diagnosable systems and sequentially diagnosable systems. We prove a necessary and sufficient condition for (t, k)-diagnosable system, and discuss a lower bound for diagnosability. Finally, we deal with a relation between (t, k)-diagnosability ...

Although transthyretin (TTR) is expressed in pancreatic alpha (glucagon) cells in the islets of Langerhans, the function of TTR in pancreatic alpha cells remains unknown. In this study, by using TTR knockout (TTR KO) mice, we determined the novel role of TTR in glucose homeostasis. We demonstrated that TTR KO mice evidenced impaired recovery of blood glucose and glucagon levels. Lack of TTR induced significantly lower levels of glucagon in the islets of Langerhans. These results suggest that TTR expressed ...

A decline in physical activity has been shown to be associated with metabolic syndrome (MetS), leading to cardiovascular events. However, this is difficult to manage well in the elderly with multiple atherosclerotic risk factors. In this study, we investigated the correlation between physical activity and clinical parameters in the presence and absence of MetS in Japanese elderly subjects with type 2 diabetes mellitus (T2DM). In addition, we determined which factor, calorie intake or physical activity, ...

Turn-to-turn short-circuit of stator winding due to deterioration of electrical insulation is one of the most probable faults in motor drive systems. This paper proposes two diagnostic methods to detect the fault based on Support Vector Machine. In the first method, magnitude and phase of load currents at fixed rotating speeds are considered as features reflecting winding condition. It is found that the method is effective particularly in slight insulation failure like one turn-to-turn short-circuit. ...

Cycle is one of the most fundamental graph classes.For a given graph, it is interesting to find cycles of various lengths as subgraphs in the graph.The Cayley graph Cay(S n , S) on the symmetric group has an important role for the study of Cayley graphs as interconnection networks.In this paper, we show that the Cayley graph generated by a transposition set is vertex-bipancyclic if and only if it is not the star graph.We also provide a necessary and sufficient condition for Cay(S n , S) to be edge-bipancyclic.
