An ovarian cyst is classically defined as a fluid-filled space larger than 24 mm, that can persist for more than 7 to 10 days in the absence of a corpus luteum. The frequenc y of this pathology is between 7 to 15%. Contrary to the follicular cyst, the luteinised follicular cyst is characterized by the presence in its periphery of a luteal tissue. The ovarian cyst is a dynamic structure. Its presence doesn't interfere with the follicular waves but can modify their characteristics. An ovarian cyst results from or induces an absence of ovulation. Ovarian cyst diagnosis and especially the differential diagnosis between follicular and luteal cysts necessarily imply the use of ultrasonography to clearly identified their diameter and thickeness. The ultrasonography sensibility is better than that of transrectal palpation. Progesteronemia interpretation supposes the preliminary definition of a threshold. Behavioural(anoestrus or nymphomany), uterine(tonicity of the uterine horns) or vaginal (mucus) abnormalities can help to direct the diagnosis. [less ▲]

Many computational intensive bioinformatics software, such as multiple sequence alignment, population structure analysis, etc., written in C/C++ are not multicore-aware. A multicore processor is an emerging CPU technology that combines two or more independent processors into a single package. The Single Instruction Multiple Data-stream (SIMD) paradigm is heavily utilized in this class of processors. Nevertheless, most popular compilers including Microsoft Visual C/C++ 6.0, x86 gnu C-compiler gcc do not automatically create SIMD code which can fully utilize the advancement of these processors. To harness the power of the new multicore architecture certain compiler techniques must be considered. This paper presents a generic compiling strategy to assist the compiler in improving the performance of bioinformatics applications written in C/C++. The proposed framework contains 2 main steps: multithreading and vectorizing strategies. After following the strategies, the application can achieve higher speedup by taking the advantage of multicore architecture technology. Due to the extremely fast interconnection networking among multiple cores, it is suggested that the proposed optimization could be more appropriate than making use of parallelization on a small cluster computer which has larger network latency and lower bandwidth.

This study investigated the influence of four modalities of wheat (Triticum aestivum L.) presentations on the performances and digestive tract characteristics of broilers (Ross). The variety of wheat was Meunier. The first dietary treatment (Milled) corresponded to milled wheat (hammer mill, sieve of 3 mm). The second treatment (Rolled) was related to rolled wheat. The third dietary treatment (Whole-Advanced) corresponded to 10 % whole wheat for first week of study (d 10 to d 17), 20 % whole wheat for second week of study (d 17 to d 24) and 30 % after d 24. The fourth treatment (Whole-Belated) was similar to the third, except a delay equals to 1 week (10 % for d 17 to d 24, 20 % for d 24 to d 31 and 30 % after d 31). Except for the first week of study, intake of Milled was inferior (p < 0.05) to other treatments. From the second week (between d 17 and d 24), growth related to Rolled was higher (p < 0.05) than two whole wheat treatments. From the third week (between d 24 and d 31), growth related to Rolled was also higher (p < 0.05) than Milled. Cumulated feed conversion ratio (FCRc) of Milled and Rolled was better (p < 0.05) than FCRc of whole wheat treatments (30 % of whole grain in fine). With this two whole wheat incorporation schemes, 20 or 30 % of whole grain was superior (p < 0.05) to Milled for FCR. The gizzards of broilers related to whole wheat were proportionally heavier (p < 0.05) than gizzards associated to Milled or Rolled. Rolled was not different (p > 0.05) from Milled for weights of gizzards. [less ▲]

Health benefits of a diet rich in fruits and vegetables are attributed in part to their contents of phenolics and other antioxidant compounds. In this research, the extraction of phenolics and antioxidant compounds from black currant was optimised for different plant organs. The extraction solvent affected yield: aqueous acetone was better than methanol and acetate or glycine buffer. In aqueous buffer, maximum yields of total phenolics and antioxidant activities were obtained at pH 3. Extraction from lyophilised materials yielded extracts with higher phenolic contents and antioxidant activities. Stability of extracts made with acetate or glycine buffer was limited while the use of a mixture of acetone/acetic acid/water for extraction allowed a high phenolic content and antioxidant capacity in dry extract to be maintained for several months. This type of extract could be incorporated in functional food, beverage or dietary supplement. (c) 2007 Elsevier Ltd. All rights reserved. [less ▲]

Bisphosphonates are the current mainstay of the management of osteoporosis worldwide. Oral daily and weekly formulations have been linked to poor adherence, yielding a decrease in antifracture efficacy, in real-life settings. Development of new bisphosphonates, with increased antiosteoclastic potency and affinity for bone matrix allowed intravenous administration and intervals between dosings to be higher than weekly. Ibandronate and zoledronic acid have been investigated in established osteoporosis. Quarterly injections of ibandronate (3 mg) have been shown to be at least as effective in increasing bone mineral density and reducing bone turnover markers as the oral ibandronate regimen, which has proven antifracture efficacy. A once-yearly infusion of zoledronic acid (5 mg) during a 3-year period significantly reduced the risk of vertebral, hip and other fractures. Intravenous administration of bisphosphonates can now be considered as an important component of the management of postmenopausal osteoporosis. [less ▲]

In this work, an empirical correlation is proposed to describe kLa as a function of operating conditions (agitation and aeration rates) and of oil and surfactant volumetric fractions in a biotransformation medium, an oil-in-water dispersion. An interaction effect between the oil and the surfactant effects was found, since oil presence increased kLa in the absence of the surfactant but had an opposite effect when Tween 80 was available in the medium. The biotransformation of methyl ricinoleate (MR) into γ-decalactone (an aroma compound of industrial interest), by the yeast Yarrowia lipolytica, was carried out at different conditions of operation, to evaluate the influence of kLa on the production of the aroma. It was demonstrated that kLa had an influence on the aroma production; however, for the low hydrophobic substrate concentration used (1.08% v/v) and cellular density of 2.0 × 107 cells mL-1, a minimal kLa value of 70 h-1 was necessary to attain the maximal aroma production. © 2007 Elsevier B.V.

Les élections de 2006 en République démocratique du Congo marquaient la fin d'une étape dans le processus de reconstruction de l'Etat après les guerres qui ont marqué la région de l'Afrique des Grands Lacs depuis les années 1990. La dispersion des votes sur de nombreux partis peu structurés lors des élections législatives, provinciales et sénatoriales marque le paysage politique congolais. L'élection présidentielle a montré une opposition entre deux grands candidats, l'un, Joseph Kabila, mieux soutenu à l'Est et l'autre, Jean-Pierre Bemba, à l'Ouest du pays. [less ▲]
