The course of the realization of the Harm Reduction program in the city of Nikolayev

The growth of drug addiction has been noted in Nikolaev. This growth has not been stopped by methods based on the use of force. The results of work in accordance with the program "Harm Reduction" are presented. The program functions on the basis of the Charity Fund "Blahodiinist" and is intended for the prevention of the spread of HIV infection in groups of risk among injecting drug users and in other groups. The realization of the program includes provision of information material, reduction of harm in connection with the use of drugs by injection and the risk of getting HIV and sexually transmitted diseases. The analysis of the results has shown the effectiveness of the program (the frequency of using condoms has increased, the number of sex partners and the number of casual liaisons have dropped, the custom of using sterile syringes has been formed). Considering that during epidemics the coverage of not less than 70% of the representative of risk groups is necessary, the program should be realized on a greater scale to increase its effectiveness.     

A microcomputer based program for the storage and retrieval of experimental animal information

A microcomputer based program for the storage and selective retrieval of experimental animal information has been developed for use on any system which runs under CP/M system software. The program has been designed to be completely conversational, to communicate with the user in French, English, or Spanish, and to allow the user to define the data format and the alphanumeric coding scheme.     

Computer program for the IBM personal computer which searches for approximate matches to short oligonucleotide sequences in long target DNA sequences.

We describe a program which may be used to find approximate matches to a short predefined DNA sequence in a larger target DNA sequence. The program predicts the usefulness of specific DNA probes and sequencing primers and finds nearly identical sequences that might represent the same regulatory signal. The program is written in the C programming language and will run on virtually any computer system with a C compiler, such as the IBM/PC and other computers running under the MS/DOS and UNIX operating systems. The program has been integrated into an existing software package for the IBM personal computer (see article by Mount and Conrad, this volume). Some examples of its use are given.     

The realization of the concept of Harm Reduction in Russia

By the present moment cases of HIV infection among injecting narcotic users (INU) have been registered in more than 100 countries. To prevent HIV infection, the program "Harm Reduction" has been developed in Britain; the program states that the prevention of HIV infection must be considered more important than the prevention of the use of narcotic drugs, as this infection is a growing danger for both drug users and public health in general. Breaking drug dependence must not be the only aim of services working with drug addicts, because this will exclude persons decisively disposed to the mode of life including the prolonged use of drugs from the sphere of their activity. Active INU having no contacts with organizations which must give them treatment and assistance find themselves in dangerous situations more often than INU maintaining contacts with such organizations. Penetration into such hidden group and its education must be the primary task. Propaganda plays a decisive role in this process, as the only way to penetrate into such group is to develop work in its territory, so that drug addicts, supplied with the necessary means could change their behavior in the desired direction. In the Russian Federation work on the project "Harm Reduction" has been carried out in 50 regions. This work has contributed to conducting teaching seminars, working out teaching programs, as well as to augmenting the interest among specialists of different professions to the problem of decreasing the spread of HIV infection. The importance of information distributed by the narcological service and the probability that very responsible persons take correct decisions on the basis of their understanding the situation have increased. The rating of public organization has risen.     

Animal research in microgravity and flight environment: lessons from the past for the future

The use of animals, and more particularly the use of non-human primates, takes on importance when studying the physiological responses involved in the adaptation to changes in gravitational loading. The "Rhesus project", now canceled, was a joint program between CNES and NASA designed to carry out simultaneous experiments of various physiological disciplines using the Rhesus monkey as a human surrogate. The choice of this species was supported by several strong arguments such as the possibility of studying several physiological systems without over-instrumenting, as well as the morphological and phylogenetical closeness with man. Within this framework, building the inflight animal facilities necessary to achieve the ambitious scientific program that was established, required state of art design and technology. Spacelab flight simulations were conducted with the goal both to obtain baseline data and to evaluate the impact of the cabin environment on the circadian timekeeping system which is involved in the regulation of almost all physiological functions and behavior. Even if this project would never fly, the results from these experiments have been a source of thoughts and lessons for the future animal research in microgravity.     

Adaptive management of coastal ecosystem restoration projects

There is a clear need to apply better and more effective management schemes to coastal ecosystem restoration projects. It is very common for aquatic ecosystem restoration projects not to meet their goals. Poor performance has led to a high degree of uncertainty about the potential success of any restoration effort. Under adaptive management, the knowledge gained through monitoring of the project and social policies is translated into restoration policy and program redesign. Planners and managers can utilize the information from the monitoring programs in an effective way to assure that project goals are met or that informed and objective decisions are made to address both ecological and societal needs. The three main ingredients of an effective adaptive management plan in a restoration project are: (1) a clear goal statement; (2) a conceptual model; and (3) a decision framework. The goal ‘drives’ the design of the project and helps guide the development of performance criteria. The goal statement and performance criteria provide the means by which the system can be judged. With the conceptual model, the knowledge base from the field of ecological science plays an active and critical role in designing the project to meet the goal. A system-development matrix provides a simple decision framework to view the alternative states for the system during development, incorporate knowledge gained through the monitoring program, and formulate a decision on actions to take if the system is not meeting its goal.     

Participation of peptides in processes involved in the development of alimentary motivation in the rabbit

On the base of behavioural and electrophysiological experiments it was suggested that in rabbits the realization of the dominant feeding motivation into the goal-directed behaviour implied at the molecular-genetical level the operative synthesis of gastro-intestinal neuropeptide gastrin or its derivatives. It was supposed that the suppression of genetic information realization in CNS under blocking of peptide synthesis led to impossibility of goal-directed alimentary behaviour organization. This mechanism was found to be specific for alimentary behaviour; any its connection with defensive motivation realization was not observed.     

The prevention of HIV/AIDS among injection narcotics users in the city of Odessa

Since August 1996 the realization of the first Ukrainian Project "HIV/AIDS Preventive Maintenance among Injecting Drug Users", based on the strategy of harm reduction, has been started in Odessa with a view to the effective counteraction to the spread of HIV/AIDS among injecting drug users (IDU). The project is being realized with the advisory and financial support of UNAIDS, UNICEF and USAID. The basic organization for the realization of the Project is the Public Movement "Faith, Hope, Love". The Project is aimed at decreasing the rate of the spread of HIV infection in cases of the non-medical use of narcotic drugs by the elaboration and adoption of measures conductive to changes in hazardous behavior. The realization of the project includes the following stages: the rapid evaluation of the situation with the injecting use of drugs in Odessa, the elaboration and adoption of preventive measures.     

Nation-Wide,Web-Based,Geographic Information System for the Integrated Surveillance and Control of Dengue Fever in Mexico

Dengue fever incidence and its geographical distribution are increasing throughout the world. Quality and timely information is essential for its prevention and control. A web based, geographically enabled, dengue integral surveillance system (Dengue-GIS) was developed for the nation-wide collection, integration, analysis and reporting of geo-referenced epidemiologic, entomologic, and control interventions data. Consensus in the design and practical operation of the system was a key factor for its acceptance. Working with information systems already implemented as a starting point facilitated its acceptance by officials and operative personnel. Dengue-GIS provides the geographical detail needed to plan, asses and evaluate the impact of control activities. The system is beginning to be adopted as a knowledge base by vector control programs. It is used to generate evidence on impact and cost-effectiveness of control activities, promoting the use of information for decision making at all levels of the vector control program. Dengue-GIS has also been used as a hypothesis generator for the academic community. This GIS-based model system for dengue surveillance and the experience gathered during its development and implementation could be useful in other dengue endemic countries and extended to other infectious or chronic diseases.     

Listen to one another and act in concert (the Renewal Project)

The organization of work on the project "Harm Reduction for Intravenous Drug Users in Kazan" is substantiated. Difficulties in the realization of such projects due to the lack of coordination between different services, also taking part in controlling the spread of drug addiction and ensuring the treatment of addicts, are emphasized. The coordination of actions of various state structures will make it possible to enhance the effectiveness of programs of harm reduction. The expediency of the development of the general state program of primary prophylaxis, realized by trained specialists with the use of effective technology, is discussed.     

A didactic computer simulation of the environmental impact of a pollution discharge

Algorithms for simulating the response of a benthic animal communityand several abiotic environmental variables to organic pollutionare described. An IBM PC compatible computer program incorporatingthese methods has been written. The program simulates the abundanceresponse of 23 species, the redox potential depth profile andseveral other sediment variables at any distance from a pointsource of pollution. The program has been designed as a teachingtool and examples of its use to study pollution biology andbiometrics are given. Received on April 3, 1990; accepted on September 6, 1990     

Probabilistic pathway representation of cognitive information

We present for mental processes the program of mathematical mapping which has been successfully realized for physical processes. We emphasize that our project is not about mathematical simulation of the brain's functioning as a complex physical system, i.e., mapping of physical and chemical processes in the brain on mathematical spaces. The project is about mapping of purely mental processes on mathematical spaces. We present various arguments--philosophic, mathematical, information, and neurophysiological--in favor of the p-adic model of mental space. p-adic spaces have structures of hierarchic trees and in our model such a tree hierarchy is considered as an image of neuronal hierarchy. Hierarchic neural pathways are considered as fundamental units of information processing. As neural pathways can go through the whole body, the mental space is produced by the whole neural system. Finally, we develop the probabilistic neural pathway model in that mental states are represented by probability distributions on mental space.     

'DNA Strider': a 'C' program for the fast analysis of DNA and protein sequences on the Apple Macintosh family of computers

DNA Strider is a new integrated DNA and Protein sequence analysis program written with the C language for the Macintosh Plus, SE and II computers. It has been designed as an easy to learn and use program as well as a fast and efficient tool for the day-to-day sequence analysis work. The program consists of a multi-window sequence editor and of various DNA and Protein analysis functions. The editor may use 4 different types of sequences (DNA, degenerate DNA, RNA and one-letter coded protein) and can handle simultaneously 6 sequences of any type up to 32.5 kB each. Negative numbering of the bases is allowed for DNA sequences. All classical restriction and translation analysis functions are present and can be performed in any order on any open sequence or part of a sequence. The main feature of the program is that the same analysis function can be repeated several times on different sequences, thus generating multiple windows on the screen. Many graphic capabilities have been incorporated such as graphic restriction map, hydrophobicity profile and the CAI plot- codon adaptation index according to Sharp and Li. The restriction sites search uses a newly designed fast hexamer look-ahead algorithm. Typical runtime for the search of all sites with a library of 130 restriction endonucleases is 1 second per 10,000 bases. The circular graphic restriction map of the pBR322 plasmid can be therefore computed from its sequence and displayed on the Macintosh Plus screen within 2 seconds and its multiline restriction map obtained in a scrolling window within 5 seconds.     

Fatigue In Teenagers on the interNET - The FITNET Trial. A randomized clinical trial of web-based cognitive behavioural therapy for adolescents with chronic fatigue syndrome: study protocol. [ISRCTN59878666]

Background  

Chronic Fatigue Syndrome (CFS) is increasingly recognized as a cause of disability and inactivity in adolescents in the Netherlands. CFS is characterized by unexplained fatigue lasting more than 6 months. Cognitive Behavioural Therapy (CBT) has proven to be effective. However, CBT availability for adolescents with CFS is limited and requires special therapeutic skills not always readily available. An alternative to the face-to-face CBT is FITNET, a web-based therapeutic program designed specifically for adolescents diagnosed with CFS, and their parents. This new CBT approach appeals to the modern youth, who grow up with internet as their main source of information. A web-based program offers the opportunity to lower thresholds for the acceptance and realization of healthcare. This treatment can be activated at any chosen time. The communication between patient and therapist can elapse asynchronously. If effective, this web-based program would greatly increase the therapeutic accessibility.     

AUGUSTUS at EGASP: using EST,protein and genomic alignments for improved gene prediction in the human genome

Background

A large number of gene prediction programs for the human genome exist. These annotation tools use a variety of methods and data sources. In the recent ENCODE genome annotation assessment project (EGASP), some of the most commonly used and recently developed gene-prediction programs were systematically evaluated and compared on test data from the human genome. AUGUSTUS was among the tools that were tested in this project.

Results

AUGUSTUS can be used as an ab initio program, that is, as a program that uses only one single genomic sequence as input information. In addition, it is able to combine information from the genomic sequence under study with external hints from various sources of information. For EGASP, we used genomic sequence alignments as well as alignments to expressed sequence tags (ESTs) and protein sequences as additional sources of information. Within the category of ab initio programs AUGUSTUS predicted significantly more genes correctly than any other ab initio program. At the same time it predicted the smallest number of false positive genes and the smallest number of false positive exons among all ab initio programs. The accuracy of AUGUSTUS could be further improved when additional extrinsic data, such as alignments to EST, protein and/or genomic sequences, was taken into account.

Conclusion

AUGUSTUS turned out to be the most accurate ab initio gene finder among the tested tools. Moreover it is very flexible because it can take information from several sources simultaneously into consideration.

     

Operant conditioning and behavioral analyses using a minicomputer.

An operant conditioning and data analysis software system was developed for use on a PDP-12A minicomputer. The operant software functions in quasi time-sharing fashion to control and acquire data from any peripheral device that operates in the binary mode. In addition to independently running different experiments in near simultaneous fashion, the program also provides information on the current status of each experiment using a cathode ray-tube display. Response data from each experimental subject is stored on magnetic tape and analyzed, off-line, by the data analysis portion of the software system. A discussion of the operation of this system is given for one possible application: visual discrimination training.     

The web and the structure of taxonomy

An easily accessible taxonomic knowledge base is critically important for all biodiversity-related sciences. At present, taxonomic information is organized and regulated by a system of rules and conventions that date back to the introduction of binomial nomenclature by Linnaeus. The taxonomy of any particular group of organisms comprises the sum information in the taxonomic literature, supported by designated type specimens in major collections. In this article, the way modern means of disseminating information will change the practice of taxonomy, in particular the Internet, is explored. Basic taxonomic information, such as specimen-level data, location of types, and name catalogues are already available, at least for some groups, on the Web. Specialist taxonomic databases, key-construction programs, and other software useful for systematists are also increasingly available. There has also been a move towards Web-publishing of taxonomic hypotheses, though as yet this is not fully permitted by the Codes of Nomenclature. A further and more radical move would be to transfer taxonomy completely to the Web. A possible model of this is discussed, as well as a pilot project, the "CATE" initiative, which seeks to explore the advantages and disadvantages of such a move. It is argued that taxonomy needs to forge better links with its user-communities to maintain its funding base, and that an important part of this is making the products of its research more accessible through the Internet.     

The data quality foundation in OMNIITOX information system

Extended Summary Goal and Scope  This paper describes the data quality foundation for the OMNIITOX information system, with regard to data quality requirements and maintenance. Main Features  The data quality concept applied in the OMNIITOX project is based on results that are successfully used in other contexts (Fig. 1). Specific data quality requirements have been developed, which are applied in data acquisition and data review. The data quality requirements and quality maintenance is supported by the OMNIITOX concept model, which supplies a common language for the users from the different disciplines. Results and Discussion  The quality requirements and the concept model have been tested during data acquisition for the information system, and have been found to be a successful framework. The results from practical work demonstrate that it is possible to have a common understanding of the concept model and quality requirements. The user's experience the initial phase of learning the concepts and quality requirements as tedious. Nevertheless, experiences show that the users will benefit from the education during the further work. A considerable amount of data has been acquired based on the data quality foundation. Conclusions  The data quality foundation has been a successful framework for managing data quality in the design and establishment of the OMNIITOX information system. The data quality concept, the concept model, and specific quality requirements are applied as quality management tools to find, acquire, document, and interpret the information. Several quality issues deriving from interdisciplinary differences between the different users have been resolved, which facilitates a common understanding and reduces the risk of misinterpretations and misuse of information. Recommendations and Outlook  An important task for the finalization of the OMNIITOX project is to secure the credibility and long-term stability of the information system. The OMNIITOX information system will somewhat have less potential to support the toxicology related assessments in Europe if any of the involved disciplines chooses to reject or not to apply the concept model and the quality requirements.     

New strategies in preventing the spread of HIV infection in Russia

Due to the joint efforts of Russian specialists, the UNAIDS program, the international nongovernmental organization "Médecins sans Frontières" (Holland) and the "Institute of Open Society" (USA), the concept of making programs on the prevention of HIV infection among the intravenous drug users has been formed in the Russian Federation. The cohort of specialists mastering modern technologies in target group has been trained, the realization of the projects of harm reduction is carried out in 25 regions. The necessity of the realization of such projects has been confirmed in 21 more regions of the Russian Federation. Taking into account the development of the epidemic of HIV in the Russian Federation with drug users being the main motive force of this epidemic, the importance and timeliness of the efforts made in this direction can scarcely be exaggerated. In working out the new federal program "Anti-HIV/AIDS" the support ans development of activities in this direction must become one of the priorities of this program.
