1. The chromosome numbers of 64 species have been studied on which 56 are investigated for the first time.
2. 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 ) 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.
4. 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.
. 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
) 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.
. 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.

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. 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 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. 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 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 , '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 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 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 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. 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 . Ainsi, le HDK se substitua au J-K en tant que≪parti democratique≫visant a rallier les elites sociales sous sa banniere, en s'appuyant sur l'autorite personnelle de Qazi Mihemed.

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, 4/ 47). The baseline lipoprotein concentration and the intake of energy and lipids were not significantly different between subjects with / and those with 4/ 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 4/ had significantly smaller reductions of LDL- than the patients with /. The changes of LDL- showed a significant difference between the patients with / and 4/ by the Kruskal Wallis test (p=0.041). The presence of 4/ predicted the degree of cholesterol reduction following dietary therapy.

Circuit techniques to enhance the linearity of input-voltage-to-current (V/I) conversion and to increase the output impedance of a current source by compensating for the low intrinsic gain of a transistor were introduced to realize a high-frequency operational transconductance amplifier (OTA) for a low supply voltage using sub-100-nm CMOS processes. Applying these techniques, a MOS th-order Gm- linear-phase low-pass filter (LPF) was realized using a 65nm CMOS process. A simplified biquad LPF that can serve as a component of a th-order LPF was newly developed by replacing OTAs with resistors. As a result, the -dB frequency bandwidth, group delay ripple, rd-order distortion, and rd-order input intercept point (IIP) were 200MHz, 2.2%, ≤ -55dB with a 100MHz input, and +10.dBm, respectively, all with a ±0.1Vp-p input signal at each input terminal in the pseudodifferential configuration. The LPF including an output buffer dissipated 60mW in the case of a 1.2V supply. Wide spurious-free dynamic range (SFDR) characteristics were confirmed up to high frequencies.

Static characteristics of two different structured InAlGaAs/InAlAs superlattice avalanche photodiodes (SLAPDs) cooled by liquid nitrogen were evaluated at a wavelength of 1.5 μm. The dark current of the SLAPD having a thick superlattice layer of 0.504 μm was 5×10^-13 A. This was successively reduced by four orders of magnitude compared to that of the thin layer SLAPD of 0.231 μm at a breakdown voltage of around 20 V. The thickened layer was effective in suppressing tunneling dark current. An output current of 1.×10^-12 A at a bias voltage of 15 V was measured for an optical input with a wavelength of 1.5 μm and a signal power of 1×10^-12 W. This showed a sharp distinction from the dark current.

Estriol antisera were raised and studied for the use in radioimmunoassay (RIA) of urinary estrogen as an aid of diagnosis of feto-placental function. Antisera to estriol-related six haptens, i.., estriol 16-glucuronide (-16-G), estriol 16-hemisuccinate (-16-succ), estriol 17-hemisuccinate (-17-succ), estriol 16, 17-dihemisuccinate (-16, 17-succ), estriol -carboxymethylether (--CME) and estriol -glucuronide (--G), were obtained by immunizing rabbits with the respective haptenbovine serum albumin (BSA) conjugate. Antiserum to -16-G-BSA reacted significantly with -16-G, -17 conjugated estrogens and free estrogens. But it did not react with - conjugated estrogens and other steroids. Similar properties were observed with antisera to -16-succ-BSA, -17-succ-BSA and -16, 17-succ-BSA, but their reactivities with -16 or -17 conjugated estrogens were slightly lower than that of anti--16-G-BSA serum. Among antisera which were raised against estriol linked to BSA via hemisuccinate varying in linking posirion, anti--16-succ-BSA serum highly reacted with -16-G, while anti--17-succ-BSA did with -17-G. Anti--16, 17-succ-BSA serum reacted with -16 and -17 conjugated estrogens to nearly the same extent. Antisera to both --CME-BSA and --G-BSA reacted with estrogens conjugated at - position, but failed to react with -16 or -17 conjugated estrogens. The latter antiserum reacted more specifically with and -G than the former. Estrogen values in pregnancy urine samples estimated by the RIA by use of anti--16-G serum were not influenced by other components in urine, and showed a good correlation of y=0.x-1.28, =0.983 with those determined by the currently available colorimetric method with -kit.

The pseudo-static analysis has been used in engineering practice to simplify the computation of the upper limit of a slope under seismic load. In this paper, the upper bound technique of limit analysis of perfect plasticity is used to determine the bearing capacity of a foundation near a down-hill slope. In this analysis (Chen et al., 1969; Chen, 1975), a logarithmic spiral rapture (Abdul-Baki et al., 1970; Sawada et al., 1984) is assumed to start at an edge of the loaded area far from the slope. A landslide is assumed to be of rigid body type with the inertia force acted at its center of gravity. The collapse state is reached when the rate of kinematic energy of the landslide together with the load is equal to the rate of dissipation of internal energy along the sliding surface. This energy balance leads to the equation of ultimate load with several parameters. The optimized numerical rcsults with respect to these parameters are compared with those by Kotter's method (Yamaguchi, 1959) and those obtained by the slice method.

A new concept for the calculation of the bearing capacity of shallow foundations is presented. The Terzaghi-Buisman equations was transformed and extended to include all possible load cases. The shape ratio was rigorously defined. Torsional moment factors considering eccentric horizontal loads were proposed and defined for the first time, in order that complete -dimensional interaction diagrams could be derived. The effect of embedded depth was also investigated and considered for special factors. The influence of cohesion was derived from Caquot's theorem of the corresponding states of stress. Experimental investigations with some interesting results are presented. A new calculation scheme is presented at the conclusion of the paper.

Laboratory model test results for the ultimate bearing capacity of two closely-spaced strip foundations on sand have been presented. The model test results have been compared with the theoretical study given by Stuart (1962). The nature of variation of the experimental efficiency factors, α_q and α_r, associated with the bearing capacity factors, N_q and N_r, are similar to those predicted by the theory; however, their magnitudes are substantially lower for S/<about . The foundation settlement at ultimate failure load increases for S/<4.5 when compared with that of an isolated foundation.

It has been shown after mathematical and mechanical investigation that Limit Equilibrium Method (LEM) can be considered as a method to obtain the necessary condition of Slip Line Method (SLM), and that the solution can be obtained under the condition that F_s=1 and ∂F_s/∂θ=O, where F_s is the safety factor and θ is the inclination of the plane on which the safety factor is defined. Next, the generalized LEM (GLEM) is proposed, dealing with the following points : (1) Triangular or quadrangular blocks can be treated; (2) Safety factors are defined also on interblock planes; and () All types of plastic problems, slope stability, bearing capacity, and earth pressure are identically formulated. Two situations regarding treatment of the moment equilibrium condition are discussed. GLEM is applied to well-known problems. The results agree well with those obtained by theoretical methods. GLEM can be used to obtain the distribution of earth pressure or bearing capacity. GLEM, Iike ordinary LEM, is very effective for the practical problems, but GLEM is more theoretical and it can result in more accurate solutions.

Failure problems of saturated soils are classified in the present study into the following four types : Type I : The failure of loose and/or normally consolidated soils under fully drained loading conditions. Type II : The same soils but under perfectly undrained conditions. Type III : The failure of dense and/or overconsolidated soils under fully drained conditions. Type IV : The same soils but under perfectly undrained conditions. The soil-water coupling limiting equilibrium analysis on the basis of the critical state concept is shown possible to draw a distinction between type I, II and IV problems, and the limitations of the analysis procedure happen in solving the type problem in the above. This is demonstrated experimentally, in which seepage failure experiments in laboratory with the use of a saturated silty sand are employed to make distinctions clearly between the four types of failure problems. The definite distinctions both in failure load and failure mode appeared in the four types of experiments are summarized as follows : (1) the smallest failure load in loose sand in the undrained condition, (2) the largest failure load with the largest failure region in dense sand under undrained loading, () the observation of no global deformation before failure within the soil under the fully drained condition that suggests the development of very localized shear deformation in the sand. Three out of four experiments are described well by the limit analysis computation mentioned above as far as the failure load and the shape and the size of the failure region after boiling failure are concerned, and thus the type III problem is identified to be the problem that should be solved by any other means in near future.

Recently we saw two patients with acute hepatitis, infected with hepatitis virus (HEV) of a rare genotype . One patient (Tokyo/2012) had traveled Spain 1 month before developing hepatitis, while the other patient (Saitama/2014) did not have history of traveling abroad. Nearly entire genomic sequence of HEV was recovered from both patients; ,336 nucleotides (nt) from the Tokyo case in 2012 (isolate name=JAO-SpaTok12, accession=LC055972) and ,306 nt from the Saitama case in 2014 (JMH-Sai14, LC055973). Phylogenetic analysis revealed that JMH-Sai14 from the Saitama patient, who denied having traveled abroad, could be classified into a subgroup of genotype , together with European isolates as well as an already reported Japanese isolate HE-JA12-0725 (850879) from a patient living in Gunma and having never traveled abroad when he/she developed hepatitis in 2012. On the other hand, the Tokyo patient's sequence segregated to a separate branch together with European isolates. Based on these findings it is possible that HEV genotype has already made inroad into Japan as in the case of .

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 (G1;2;

;4) was performed. At first, we moved drugs from solution with pH 1.2 (1.2±0.05) to pH .0 (.0±0.05) and measure concentration of omeprazole in solution by high-performance liquid chromatography. According to our self-developed formula, pH exposure time of resistance to PDGR for omeprazole is 4 minutes, i.. the active substance should not be released within 4 minutes at pH . The exposure at the second stage was conducted with pH 4 (4.0±0.05), that imitated gastric pH after PPI administration. And then we also moved drugs to pH with the subsequent measurement of omeprazole concentration.

Results

Omeprazole concentrations after 4, 10, 15, 20, 30, 45, 60 minutes in pH

solution at the first stage were different for OO and generics. For OO, these values were 4,±0,%; 41,4±,0%; 62,±4,0%; 79,5±2,%; ,5±2,%; ,±2,%; ,±4,4%; for Generic1 - 0; 49,±,%; 88, ±2,%; 90,4±,%; 88, 2±2,2%; 87,±2,0%; 85,±1,1%; for Generic2 - 0; 30,±,%; 66,±,2%; 76,4±,4%; ,±5,%; 86,0±,%; ,±,%: for Generic - ,±,%; ,5±1,%; , ±,2%; ,±2,%; ,±2,1%; ,1±2,0%; ,0±2,4%; for Generic4 - ,5±1,%; ,4±0,%; ,2±1,2%; , ±0,%; ,±0,%; ,±0,%; ,±1,1%, respectively.

An analysis of the omeprazole concentration in pH

solution at the second stage revealed the following parameters after the same time: for OO - 4,4±0,%; 40, 5±,0%; 62,±2,0%; ,0±,1%; 85,4±2,%; ,±,4%; ,±,5%; for Generic1 - 0; 67,0±,%; 89,±2,%; 91, ±4,%; 89,1±1,%; 88,±1,4%; 87,±1,2%; for Generic2 - 0; 42,2±5,%; 75,1±,%; ,0±,0%; 88,4±,2%; 88, ±1,%; 87,±1,0%; for Generic4 - 85,5±0,5%; 85,±0,5%; ,±0,%; ,±,0%; ,4±0,%; ,4±0,%; ,±0,4%, respectively. Generic release and degradation were completely realized at pH 4.

Conclusion

Decreased gastric stability of Generic

and Generic4 makes PDGR and inhibited gastric acid secretion due to PPIs administration the potential causes of decreased enteric-coated acid-labile drugs stability.
