The nucleolus is the morphological visualization of ribosome biogenesis. The spatial distribution of nucleolar DNA has been investigated in Ehrlich tumor cells by various immunogold labelling techniques. The DNase 1-sensitive regions within the nucleolus have been identified by in situ nick-translation at the ultrastructural level. The precise nucleolar location of rDNA and rRNA has been further specified by in situ hybridization and electron microscopy. Our results indicate that the fibrillar centers are the sole nucleolar structures where DNase 1-hypersensitive sequences, rDNA and rRNA are located together. These findings strongly suggest that rRNA gene transcription takes place within the confines of the fibrillar center, probably close to the boundary regions to the surrounding dense fibrillar component.

Eleven subjects were equipped with a cluster of 120 markers on the scapula. Forward humeral elevation was then performed. Robust estimators are used in order to eliminate high deformation. Results underline the modification of the best cluster during elevation. Markers located on the lateral posterior part of the acromion were identified. They could be the best ones to measure dynamic scapula rotation during entire elevation. [less ▲]

In location-based services (LBSs), the service is provided based on the users' locations through location determination and mobility realization. Most of the current location prediction research is focused on generalized location models, where the geographic extent is divided into regular-shaped cells. These models are not suitable for certain LBSs where the objectives are to compute and present on-road services. Such techniques are the new Markov-based mobility prediction (NMMP) and prediction location model (PLM) that deal with inner cell structure and different levels of prediction, respectively. The NMMP and PLM techniques suffer from complex computation, accuracy rate regression, and insufficient accuracy. In this paper, a novel cell splitting algorithm is proposed. Also, a new prediction technique is introduced. The cell splitting is universal so it can be applied to all types of cells. Meanwhile, this algorithm is implemented to the Micro cell in parallel with the new prediction technique. The prediction technique, compared with two classic prediction techniques and the experimental results, show the effectiveness and robustness of the new splitting algorithm and prediction technique.

Eighteen core samples from PETROBRAS well 1-JD-1-AM (Jandiatuba area. Solimoes Basin. northwestern Brazil) have been studied for miospores. Fifty-three species are identified. This assemblage is tentatively correlated with the Z Phylozone of the BZ Oppel Zone (Steemans, P., 1989. Palynostratigraphie de l'Eodevonien dans l'ouest de l'Europe. Professional Paper. Memoires Explicatifs pour les Caries Geologiques and Mineralogiques de la Belgique, 27, pp. 453.), dated late Lochkovian, This is in accordance with previous age determinations based on chitinozoans and acritarchs. Numerous representatives of the miospore genus Dictyotriletes are observed. These enable recognition of the Dictyotriletes emsiensis morphon. an informal classification unit which includes Dictyotriletes granulatus, D. emsiensis, Dictyotriletes cf. subgranifer, specimens previously misassigned to D. subgranifer and some Dictyotriletes spp. provisionally left in open nomenclature. Since all intermediate forms from typical D. granulatus to typical D. emsiensis coexist. it is currently difficult to determine the base of "F" Interval Biozone in South America as originally defined in Western Europe. It is suggested. therefore. that the base of the "Ems" Biozone defined in Brazil cannot be correlated with the base of die "E" Biozone. Instead. it be included in an interval of uncertainty ranging from the European "Si" to "E" Biozones. Indeed. the underlying "NsZ" Biozone from South America, contains species not known below the "Si" Biozone. Here, the D. emsiensis morphon Assemblage Zone is erected, which may, be coeval with the "N" through "E" Biozones of Western Europe. The PISA palynoflora from the Parana Basin is also attributed to this new biozone. However, in the absence of species observed in the "BZ" Biozone (and also in the Solimoes Basin). the PISA assemblage could be somewhat older than that of well 1-JD-1-AM. (C) 2004 Elsevier B.V.

Any location decision takes into account many variables and processes. In order to apprehend them, we propose a "simulation game". Indeed, this one presents the great merit of putting the student in a problematic situation and leads him to understand certain attitudes. However, a good finality information, and on the other hand, a fundamental learning. Theoretical knowledge so envisaged will permit a better understanding of the decision process and will improve its efficency. [less ▲]

This paper presents an overview of the state of art of ship impact analysis on lock gates. First, the different kinds of analysis are presented, which are: empirical approach, analytical-rational approach, and finite element methods performed with quasi-static analysis or dynamic analysis. A discussion on the hypothesis and the calculus time required by each method is carried out with a view to clarify the state-of-practice for engineers. Then, a quasi-static analysis by finite elements modeling a ship impact is performed on the specific case of a new lock gate designed in Belgium for the “Seine-Escaut Est” project. The results suggest some design recommendations to provide a ductile behavior and so impact strength for the gate structure. [less ▲]

The Locked-In syndrome(LIS) is defined by: (i) the presence of sustained eye opening (bilateral ptosis should be ruled out as a complicating factor);(ii) preserved awareness; (iii) aphonia or hypophonia; (iv) quadriplegia or quadriparesis; and (v) a primary mode of communication that uses vertical or lateral eye movement or blinking. Acute ventral pontine lesions are its most common cause. Following such brainstem lesions patients may remain comatose for sometime and then gradually awaken, remaining paralyzed and voiceless, superficially resembling the vegetative state. Background. – It has been shown that more than half of the time physicians fail to recognize early signs of awareness in LIS. Given appropriate medical care,life expectancy may be several decades but the chances of good motor recovery remain small. Eye-controlled computer technology now allows LIS patients to communicate and control their environment. Recent studies show that most LIS patients self-report meaningful quality of life and the demand for euthanasia is infrequent. Conclusion. – Patients suffering from LIS should not be denied the right to die – and to die with dignity –but also they should not be denied the right to live–and to live with dignity and the best possible pain and symptom management and revalidation.

The locked-in syndrome (pseudocoma) describes patients who are awake and conscious but selectively deefferented, i.e., have no means of producing speech, limb or facial movements. Acute ventral pontine lesions are its most common cause. People with such brainstem lesions often remain comatose for some days or weeks, needing artificial respiration and then gradually wake up, but remaining paralyzed and voiceless, superficially resembling patients in a vegetative state or akinetic mutism, In acute locked-in syndrome (LIS), eye-coded communication and evaluation of cognitive and emotional functioning is very limited because vigilance is fluctuating and eye movements may be inconsistent, very small, and easily exhausted. It has been shown that more than half of the time it is the family and not the physician who first realized that the patient was aware. Distressingly, recent studies reported that the diagnosis of LIS on average takes over 2.5 months. In some cases it took 4-6 years before aware and sensitive patients, locked in an immobile body, were recognized as being conscious. Once a LIS patient becomes medically stable, and given appropriate medical care, life expectancy increases to several decades. Even if the chances of good motor recovery are very limited, existing eye-controlled, computer-based communication technology currently allow the patient to control his environment, use a word processor coupled to a speech synthesizer, and access the worldwide net. Healthy individuals and medical professionals sometimes assume that the quality of life of an LIS patient is so poor that it is not worth living. On the contrary, chronic LIS patients typically self-report meaningful quality of life and their demand for euthanasia is surprisingly infrequent. Biased clinicians might provide less aggressive medical treatment and influence the family in inappropriate ways. It is important to stress that only the medically stabilized, informed LIS patient is competent to consent to or refuse life-sustaining treatment. Patients suffering from LIS should not be denied the right tot die - and to die with dignity - but also, and more importantly, and pain and symptom management. In our opinion, there is an urgent need for a renewed ethical and medicolegal framework for our care of locked-in patients. [less ▲]

The development of intensive care has considerably increased the number of patients surviving severe brain damage. In clinical practice, traumatic and non-traumatic coma is a frequent problem and the main preoccupations of relatives and physicians is the neurologic recovery that may range from absence of cognitive and motor impairments to severe disability or death. The American Congress of Rehabilitation Medicine defined Locked-In Syndrome (LIS) with the presence of sustained eye opening, intact cognitive function, aphonia or severe hypophonia, quadriplegia or quadriparesis and a primery and elementary code of communication that use vertical or lateral eye movement or blinking of the upper eyelid. LIS is typically caused by a ventral pontine lesion of the brainstem. LIS infrequently occurs in children and in adults and patients may wrongly be considered as being in a coma or in vegetative state/unresponsive wakefulness state. In order to avoid this misdiagnosis, our group developed active paradigms in which participants are instructed to voluntarily direct their attention to a target stimulus. Limitations of communication make quality of life assessments in LIS patients particularly difficult. Some physicians who take care of acute LIS or healthy individual may consider that the quality of life of a LIS is very limited. However, studies have shown that patients with severe diseases or motor impairments do not necessarily self-report a poor quality of life. [less ▲]
