Phytoestrogen is molecularly almost similar with and acts the same as estrogen and is found a lot in several fruits and leaves grown either in tropical or subtropical countries. However, the quantity of molecular contents are not yet known exactly. In menopause and andropause, people need substitution of estrogens as a replacement therapy of sex hormone, due to the significant hormone decline and impacted disturbance of several organ functions and thus progressively causing severe organ dysfunctions. The objective of this study was to know the estrogen content by analyzing extractions of pegaga, green clover leaves, tomato and papaya fruit of which certain communites have overviewed contents of the leaves and fruit The samples which were collected for this purpose used 10 times replication in four different groups: the pegaga, green clover leaves, tomato and papaya fruit. All these groups were divided into two (2) subgroups based on the process or subspecies. All samples were made as an infusion 1:4) w/v), and then extracted after centrifugation 1000xg for 15mnts, with 1:5 petroleum ether) v/v). After it was evaporated, each extraction then was kept dry-frozen at –20° C until the analysiswas performed. Solid phase Radioimmunoassay technique was used to identify the estrogen contents, up to a total of 80 samples The binding percentage of each sample was then interpolated on a logit-log paper to find out the real concentrations.14 The lowest estrogen level was found in fresh pegaga leaves extract (Mean+SD) was 47.9+5.5 pg/g, but in dry leaves extract the level was increased twice, about 96.1+11.2 pg/g. Meanwhile the estrogen level in fresh green clover leaves extract was 538.0+30.5 pg/g, more than ten times higher compared to fresh pegaga level, but twice lower than the estrogen level compared to dry green clover leaves extract, which was 1068.0+97.2 pg/g. In the fruit group, the fibrin part of tomatoes had more or less the same estrogen content compared with Thai papaya subspecies, 1037.0+37.7 pg/g and 1175.0+67.7 pg/g, respectively. On the other hand, it was noted that the inner part/fibrin part of tomato had a higher estrogen level of four (4) times compared to the outer part which was 315.0+18.4 pg/g. While it was noted that local Java papaya besides being not so sweet, the estrogen level was also not as high or the same as that found in fresh green clover which is 530.1+50.7 pg/g and 538.0+30.5 pg/g. Based on this study so far, it can be concluded that semanggi/green clover, tomato and papaya could be suggested as a replacement therapy for certain people who are considered to have reduced estrogen content, except that pegaga leaves are not recommended. The last mentioned plant besides that it is difficult to obtain, its estrogen content is also very low.

SummaryThe solid-phase radioimmunoassay method has been applied to the measurement of fibrinogen. The method is extremely sensitive, being able to detect fibrinogen concentrations as low as 10 ng/ml. The immunoreactivity of fibrinogen proteolysis products differs from that of native fibrinogen, early proteolysis products showing enhanced immunoreactivity which decreases progressively with further digestion.

SummaryTwo important factors concerning the management of hemophilia in France are considered.The supply of factors VIII and IX for replacement therapy meets the current demand but as the demand increases with the development of self-infusion programs, the production will also have to increase. This can only be done through more effective use of all of the blood components and will require careful evaluation of the needs of each patient.Programs which teach self-infusion and the other aspects of home care are gradually allowing the hemophiliac and his family better understanding of the disease. These programs are developing slowly in France but must be expanded to improve the general care of all French hemophiliacs.

Our analysis documents that the existence of hidden “holes” in the capital of not yet failed banks - while creating intertemporal pressure on the actual level of capital - leads to changing of maturity of loans supplied rather than to contracting of their volume. Long-term loans decrease, whereas short-term loans rise - and, what is most remarkably, by approximately the same amounts. Standardly, the higher the maturity of loans the higher the credit risk and, thus, the more loan loss reserves (LLP) banks are forced to create, increasing the pressure on capital. Banks that already hide “holes” in the capital, but have not yet faced with license withdrawal, must possess strong incentives to shorten the maturity of supplied loans. On the one hand, it raises the turnovers of LLP and facilitates the flexibility of capital management; on the other hand, it allows increasing the speed of shifting of attracted deposits to loans to related parties in domestic or foreign jurisdictions. This enlarges the potential size of ex post revealed “hole” in the capital and, therefore, allows us to assume that not every loan might be viewed as a good for the economy: excessive short-term and insufficient long-term loans can produce the source for future losses.

[8-Neopentylglycine]oxytocin (II) and [8-cycloleucine]oxytocin (III) were prepared by a combination of solid-phase synthesis and fragment condensation. Both analogues exhibited decreased uterotonic potency in vitro, each being about 15-30% that of oxytocin. Analogue II also displayed similarly decreased uterotonic potency in vivo and galactogogic potency. On the other hand, analogue III exhibited almost the same potency as oxytocin in the uterotonic assay in vivo and in the galactogogic assay.

An analysis of the uterotonic potencies of all analogs having substituted L- or D-tyrosine or -phenylalanine in position 2 and L-arginine, D-arginine or D-homoarginine in position 8 was made. The series of analogs already published was completed by the solid phase synthesis of ten new analogs having L- or D-Phe, L- or D-Phe(2-Et), L- or D-Phe(2,4,6-triMe) or D-Tyr(Me) in position 2 and either L- or D-arginine in position 8. All newly synthesized analogs were found to be uterotonic inhibitors. Deamination increases both the agonistic and antagonistic potency. In the case of phenylalanine analogs the change of configuration from L to D in position 2 enhances the uterotonic inhibition for more than 1 order of magnitude. The L to D change in position 8 enhances the inhibitory potency negligibly. Prolongation of the side chain of the D-basic amino acid in position 8 seems to decrease slightly the inhibitory potency if there is L-substituted amino acid in position 2. On the other hand there is a tendency to the increase of the inhibitory potency if there is D-substituted amino acid in position 2.

Two {Met(0)6}deacetyl-thymosin β4analogs containing Phe(4F) or Tyr(Me) at position 12 were synthesized by the manual solid-phase method, and their anti-inflammatory effect on carrageenin-induced edema in the mouse paw was studied. Fluorination of the para-position of Phe12resulted in a marked antiinflammatory effect on carrageenin-induced edema in the mouse paw compared with that of our synthetic {Met(0)6}deacetyl-thymosin β4, but the other analog, {Met(0)6, Tyr(Me)12}deacetyl-thymosin β4, showed a marked reduction of the anti-inflammatory effect.

This paper is concerned with a class of stochastic processes or random fields with second-order increments, whose variograms have a particular form, among which stochastic processes having orthogonal increments on the real line form an important subclass. A natural issue, how big this subclass is, has not been explicitly addressed in the literature. As a solution, this paper characterizes a stochastic process having orthogonal increments on the real line in terms of its variogram or its construction. Our findings are a little bit surprising: this subclass is big in terms of the variogram, and on the other hand, it is relatively “small” according to a simple construction. In particular, every such process with Gaussian increments can be simply constructed from Brownian motion. Using the characterizations we obtain a series expansion of the stochastic process with orthogonal increments.

In gaze-based Human-Robot Interaction (HRI), it is important to determine human visual intention for interacting with robots. One typical HRI interaction scenario is that a human selects an object by gaze and a robotic manipulator will pick up the object. In this work, we propose an approach, GazeEMD, that can be used to detect whether a human is looking at an object for HRI application. We use Earth Mover’s Distance (EMD) to measure the similarity between the hypothetical gazes at objects and the actual gazes. Then, the similarity score is used to determine if the human visual intention is on the object. We compare our approach with a fixation-based method and HitScan with a run length in the scenario of selecting daily objects by gaze. Our experimental results indicate that the GazeEMD approach has higher accuracy and is more robust to noises than the other approaches. Hence, the users can lessen cognitive load by using our approach in the real-world HRI scenario.
