Affecting more than half of menstruating women, dysmenorrhea is a cramp which causes abdominal or lower back pain just before or during a menstruation. In western medicine, non-steroidal anti-inflammatory drugs (NSAIDs) are normally used to treat primary dysmenorrheal symptoms. Despite their rapidity in relieving pain, NSAIDs have many serious side effects on the liver, kidney, and gastrointestinal tract. Thai traditional medicines comprise many preparations for treating dysmenorrhea, especially Prasaplai preparation which has been listed in the Thai traditional common household drug list since 2006. The use of Prasaplai was originated about 100 years ago and is still being used in the present time to treat dysmenorrhea. This review focuses on the history of the preparation, active ingredients, and biological activities especially on cyclooxygenase inhibitor, artifacts occurred in the preparation, quantitative analysis, and clinical trial of Prasaplai formulation.

The removal rates of gross production and organic matters were investigated in the Lake Paldangho. In 1995 and 1996, soils and litter sarraples were collected and annual mean production and removal rates were calculated. Communities in the Lake Paldangho were Phragrnites communis, Miscanthus sacchariflorus, Typha aegustata and Scirpas tahernaemoutani. Removal constants of aquatic plant communities estimated by the mathematical theoretical models, were 0.826, 0.567, 0.571 and 0.751, respectively. The durations of reaching half of initial organic amounts were 0.839 yeras, 1.221 years, 1.213 years and 0.922 years respectively at the steady state of removal and accumulation for organics For organics, the rapidity of removal were more speedy P. communis, S.tahernaemontani, T. augustata, M sacehariflorus in order.

Using 200 porcine colon tissues, the efficiencies of three isolation methods of Campylobacter from porcine intestines were compared: Method 1, direct streaking of colon mucosa; Method 2, direct inoculation of intestinal contents with a swab; Method 3, inoculation of pre-enriched medium. A total of 460 Campylobacter isolates were obtained from 178 samples (89%) by direct streaking of colon mucosa, 142 samples (71%) by direct streaking of a swab, and 94 samples (47%) by pre-enrichment of intestinal contents in Preston broth. Direct streaking of colon mucosa was superior to the other two isolation methods, in terms of rapidity and higher efficiency. When isolates were identified with various biochemical tests and PCRs specific to 16s rRNA, mapA, and ceuE, C. coli was the predominant species (87%) in porcine, whereas the rest of the isolates were identified as C. lanienae.

With the rapidity of the development on electronic technology, various mobile devices are produced to make human life more convenient. The user is always in constant search of middle with ease of deployment. Therefore, the development of infrastructure and application with ubiquitous nature gets a growing keen interest. Recently, the number of pervasive network services is expanding into ubiquitous computing environment. To get desired services, user presents personal details about this identity, location and private information. The information transmitted and the services provided in pervasive computing environments (PCEs) are exposed to eavesdropping and various attacks. Therefore, the need to protect this environment from illegal accesses has become extremely urgent. In this paper, we propose an anonymous authentication and access control scheme to secure the interaction between mobile users and services in PCEs. The proposed scheme integrates a biometric authentication in PKI model. The proposed authentication aims to secure access remote in PCE for guaranteeing reliability and availability. Our authentication concept can offer pervasive network service users convenience and security.

Nuclear bodies are subnuclear, spheroidal, and membraneless compartments that concentrate specific proteins and/or RNAs. They serve as sites of biogenesis, storage, and sequestration of specific RNAs, proteins, or ribonucleoprotein complexes. Recent studies reveal that a subset of nuclear bodies in various eukaryotic organisms is constructed using architectural long noncoding RNAs (arcRNAs). Here, we describe the unifying mechanistic principles of the construction and function of these bodies, especially focusing on liquid-liquid phase separation induced by architectural molecules that form multiple weakly adhesive interactions. We also discuss three possible advantages of using arcRNAs rather than architectural proteins to build the bodies: position-specificity, rapidity, and economy in sequestering nucleic acid-binding proteins. Moreover, we introduce two recently devised methods to discover novel arcRNA-constructed bodies; one that focuses on the RNase-sensitivity of these bodies, and another that focuses on "semi-extractability" of arcRNAs.

This study concerns an advanced 3D surface reconstruction method that the vertices of surface model can be completely matched to the unstructured point cloud measured from arbitrary complex shapes. The concept of bounding voxel model is introduced to generate the mesh model well-representing the geometrical and topological characteristics of point cloud. In the reconstruction processes, the application of various methodologies such as shrink-wrapping, mesh simplification, local subdivision surface fitting, insertion of is isolated points, mesh optimization and so on, are required. Especially, the effectiveness, rapidity and reliability of the proposed surface reconstruction method are demonstrated by the simulation results for the geometrically and topologically complex shapes like dragon and human mouth.

Evolutionary algorithm is recognized as a promising approach to solving multi-objective combinatorial optimization problems. When no preference information of decision makers is given, multi-objective optimization problems have been commonly used to search for diverse and good Pareto optimal solution. In this paper we propose a new multi-objective evolutionary algorithm based on competitive coevolutionary algorithm, and demonstrate the applicability of the algorithm. The proposed algorithm is designed to promote both population diversity and rapidity of convergence. To achieve this, the strategies of fitness evaluation and the operation of the Pareto set are developed. The algorithm is applied to job shop scheduling problems (JSPs). The JSPs have two objectives: minimizing makespan and minimizing earliness or tardiness. The proposed algorithm is compared with existing evolutionary algorithms in terms of solution quality and diversity. The experimental results reveal the effectiveness of our approach.
