Libido and PTSD

The most frequent PTSD treatment is group therapy. Experiences gained from this kind of work warn us of big difficulties, especially if psychotherapist is an analytically oriented person. He has to do with non-presence of insight. These groups are dominated by projection and catharsis, which is often a source of secondary traumas. However, patients are fond of these group sessions. In the dynamics of such group sessions, what can be recognized is the tendency towards repression of the actual problems a PTSD patient has in his family, at work and in social relations. One of these problems, marked for the intensity of repression and negation, is the problem of libido. Weakness of potency and other libidinous problems are often the source of family problems as well as auto-aggressive acts. Libidinous problems are a taboo topic and the task of a psychodynamically oriented psychotherapeutist is to point out at this problem. Psychotherapeutic process changes its dynamics while directing verbalization to the problem of libido. Apart from readiness for solving the problem, patients with PTSD diagnosis show an interest in the members of their family being involved into psychotherapy. A special dynamics is being developed while solving the libidinous problems of the widows whose husbands were killed in war

Survey of detection techniques, mathematical models and simulation software in pedestrian dynamics

The study of pedestrian dynamics has become in the latest years an increasing field of research. A relevant number of technicians have been looking for improving technologies able to detect walking people in various conditions. Several researchers have dedicated their works to model walking dynamics and general laws. Many studiers have developed interesting software to simulate pedestrian behavior in all sorts of situations and environments. Nevertheless, till nowadays, no research has been carried out to analyze all the three over-mentioned aspects. The remarked lack in literature of a complete research, pointing out the fundamental features of pedestrian detection techniques, pedestrian modelling and simulation and their tight relationships, motivates the draft of this paper. Aim of the paper is, first, to provide a schematic summary of each topic. Secondly, a more detailed description of the subjects is displayed, pointing out the advantages and disadvantages of each detection technology, the working logic of each model, outlining the inputs and the provided outputs, and the main features of the simulation software. Finally, the obtained results are summarized and discussed, in order to outline the correlation among the three explained themes

Flow cytometry for microbial sensing in environmental sustainability applications: current status and future prospects

Practical and accurate microbial assessment of environmental systems is predicated on the detection and quantification of various microbial parameters in complex matrices. Traditional growth-based assays, considered to be both slow and biased, are increasingly being replaced by optical detection methods such as flow cytometry. Flow cytometry (FCM) offers high-speed multi-parametric data acquisition, compatibility with current molecular-based microbial detection technologies, and is a proven technology platform. The unique technical properties of flow cytometry have allowed the discrimination of bacteria based on nucleic acid staining, microbial identification based on genomic and immunologic characteristics, and determination of cell viability. For this technology to achieve the ultimate goal of monitoring the microbial ecology of distributed systems, it will be necessary to develop a fully functional, low cost, and networkable microsystem platform capable of rapid detection of multiple species of microorganisms simultaneously under realistic environmental conditions. One such microsystem, miniaturized and integrated in accordance with recent advances in micro-electro-mechanical systems technology, is named the Micro Integrated Flow Cytometer. This manuscript is a minireview of the current status and future prospects for environmental application of flow cytometry in general, and micro-flow cytometry in particular.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/75610/1/j.femsec.2004.01.014.pd

The Impact of Psychological Testing on the Patients Suffering from Stomatopyrosis

Stomatopyrosis is commonly associated with stressful situations, which implies the importance of psychological conditions of the patients with this symptom. Patients suffering from burning mouth syndrome suffered from some psychical disturbances as well. The fact that depression and anxiety are closely connected with stomatopyrosis has been scientifically confirmed. The data which systematically led to this conclusion suggest the possibility of the existence of a psychogenic disturbance as an aetiological factor which leads to stomatopyrosis. Research which might be conducted in order to relate psychogenic disturbances with stomatopyrosis by means of various drugs and procedures, might provide an insight into the relatedness of these factors, which would enable us to treat the cause and not the consequence.This research has been directed towards establishing this »relatedness« by means of psychopharmatics and psychotherapy, and has been confirmed by means of psychological depression and anxiety tests. The research has been conducted on 120 respondents suffering from stomatopyrosis, who were also, as previously diagnosed, suffering from a psychical disturbance. The respondents were divided into 4 groups. Each group contained 30 respondents suffering from stomatopyrosis as the basic symptom, but with different psychogenic disturbances. These groups were: 1) antidepressants, 2) anxiolytics, 3) autogenic training and 4) control group. A detailed clinical and psychiatric check-up was conducted before the treatment started, and was repeated several times in different intervals: after a month, after two months and after four months. Respondents are still undergoing a therapy. Subjective assessment of the intensity of the burning sensation was obtained according to Visual analogue scale and two psychological questionnaires (depression test and anxiety test). Conclusion is: 1) Antidepressants and anxiolytic drugs have a prominent role in the treatment of stomatopyrosis. Psychological tests conducted after a four-month period have shown improvement – there was a decrease in anxiety – 7.5%–8.8%, while depression has in some of the tested groups completely disappeared. At the same time, subjective evaluation of the intensity of the symptom has, according to VAS, showed a fall from 6.93–7.8 cm to 2.13–3.0 cm. At the beginning of the treatment, symptoms were described as »pretty often« with 36.7%–76.7% respondents, and as »permanent« with 23.3%–63.3% respondents. At the end of the treatment, the most frequent description regarding the frequency of the symptoms was »very rarely«. 2) Autogenic training – psychotherapeutic anxiolytic technique – is the therapy of choice as far as stomatopyrosis is concerned, as it both eliminates the problems and emotionally rehabilitates the patient. 3) As far as the therapeutic progress is concerned, it can be taken as the »progress« of the time when the symptoms appear: during the treatment, the frequency and the duration of the symptoms have been shortened at night, while their occurrence during the day has been reported as relatively more frequent

Hydrogen-Based Activity Enhancement in Sediment Cultures and Intact Sediments

The potential for hydrogen gas to stimulate microbial respiratory activity in sediments was investigated. Cell elutions from Passaic River (NJ), San Diego Bay (CA), and Marine Harbor sediments were amended with hydrogen gas to evaluate its impact on microbial activity measured by intracellular reduction of 5-cyano-2,3-ditolyl tetrazolium chloride (CTC). The transferability of this approach to sediment slurries and static sediment columns was evaluated based on microbial activity enhancement in Marine Harbor sediments. Results indicate that microbial activity can be increased by a factor of 2–3 at a threshold hydrogen concentration range (0.5 to 1.5 μM). Terminal restriction fragment (T-RF) length polymorphism analysis indicated that the community response to hydrogen resulted in the emergence of previously recessive populations. The causal relationship between hydrogen amendment and an increase in CTC-active cells was most likely due to community structure shifts, as evidenced by the emergence of new T-RFs (19% of total) at hydrogen concentrations above 1.5 μM. No RF was dominant within this emergent group, and no chlororespirers were detected within this group, the latter probably due to the lack of enrichment of halogenated compounds. Nevertheless, the transferability of the observed relationship between hydrogen gas amendment and microbial activity to complex sediment samples suggests a promising remedial strategy for in place contaminated estuarine sediments.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63230/1/ees.2006.0078.pd

Psychogenic Factors in the Aetiology of Stomatopyrosis

This research has been conducted on the basis of the association between a psychogenic factor and stomatopyrosis as its consequence. Stomatopyrosis is characterised as a burning sensation or as pain in the mouth cavity with clinically normal oral mucosa. It typically occurs with elderly female population, aged on average 67. Burning mouth as a symptom occurs primarily on the lips, although it may be located on some other sites on the oral mucosa. There are various etiological factors influencing the emergence of stomatopyrosis. They are divided into local factors, related to candidiasis, dysfunction, problems caused by dentures; systemic factors, with hormonal or immunological disturbance, medicines, etc; and, finally, psychogenic factors, characterised by various psychological states and conditions like depression, anxiety, adaptability and emotional stability. The objective of this research was to prove that psychogenic factors cause the burning mouth syndrome sensation. Methods which helped us to establish the link between psychogenic factors and the emerging of stomatopyrosis were general history of the respondents, clinical history, which included both objective and subjective assessment, and psychological rating scales and tests. The results have shown that sex of the respondents does not make any difference. Diagnosis of the oral disease shows that burning is the symptom as well as in the diagnosis of the disease, that localisation of the symptom is primarily on lips, followed by tongue, cheeks, and palate. The description of the symptoms shows that respondents with stomatopyrosis complain of burning and dryness in the mouth cavity. As far as the intensity of the symptom is concerned, the results have shown that the symptom is in most cases unbearable. The frequency of the occurrence of the symptoms said to be continuos. The typical time when the symptom occurs is daytime, followed, by night and evening, day and night. Tension dentures and hot food intensify the symptom. Subjective change in taste is present in the high percentage. Visual analogue scale shows a high degree subjective assessment of the symptoms in the mouth cavity. Thermoestesiometry has established that there are no pathological changes on the oral mucosa. Psychological rat-ing scales and tests have established the presence of psychical changes in a high percentage. What we took into account were the most frequent changes: depression, anxiety, adaptability and emotional stability. We also established a systematic and a psychiatric diagnosis that was necessary for making the right choices when treating people with stomatopyrosis. Stomatopyrosis is the state whose factor, apart from local and systematic factors, may be psychogenic factor. We think that stymatopyrosis may be psychosomatic state that can be cured or treated by appropriate treatment, which includes psychiatric treatment as well
