How to Use This Guide* Invertebrates are playing an increasingly important role in biomedical research. Because many of their biological processes are temperature dependant, they have allowed us to view biochemical pathways and intermediate steps in ways that would be impossible with birds or mammals. Some have cells or organs similar to those found in man but greatly enlarged. The giant axon in the squid and the muscle cells in barnacles are the largest in the animal kingdom. Octopuses have the most complex brain of all invertebrates; which include long and short-term memories. Aplysia are used in many different types of nervous system studies. Sea squirts have been used to study kidney stones and squid are used in multiple sclerosis research. From scallop to sea slug, invertebrates have served as models of human and animal disease. Invertebrates are relatively easy to maintain, less expensive, and less labor intensive than more traditional laboratory animals. From a societal standpoint, invertebrates may be more acceptable as laboratory animals than vertebrates. Many researchers, either by law or policy, are required to consider ways to reduce the number of animals proposed for an experiment, refine their techniques to minimize pain and distress to the animals, and replace the animal model with a non-animal model or a taxonomically lower species. Use of the invertebrate is considered a replacement alternative to the use of vertebrates. Since research has not yet shown invertebrate cognition of what would be considered pain in mammals and birds, their use is also a refinement alternative. molluscs.htm[3/31/2015 9:00:20 AM] "Information resources on the care and use of molluscs" This guide, Information Resources on the Care and Use of Molluscs, provides a snap shot of how Molluscs are being used in research and, just as important, how they are cultured, reared, and housed in the laboratory and elsewhere.

Abstract: Measured responses of biochemical or physiological indicators have been suggested to reflect thresholds where pollutants exert their initial effect. Responses in cellulolytic enzyme activity and DNA strand breakage of the Asian clam Corbicula fluminea exposed to cadmium in the laboratory were measured and metal body burdens were determined concurrently. Clams were exposed to aqueous cadmium concentrations of 3, 6, 12, or 25 ppb for 23 and 28 molluscs.htm[3/31/2015 9:00:20 AM] "Information resources on the care and use of molluscs" d. Cadmium concentrations in clam tissue were highest in lower cadmium treatments, and body burdens increased with length of exposure in only the 28 d experiment. Cellulolytic enzyme activity decreased with increasing cadmium concentrations for clams in the 28 d experiment. Induced enzyme activities were observed in cadmium treatments for both experiments and are thought to precede declines in activity through the length of exposure. Significant reductions in DNA strand lengths of cadmium exposed clams were observed by wk 3 in the 23 d exposure and by wk 2 in the 28 d exposure. Reduced DNA strand lengths in these cadmium treatments for the 28 d exposure precede significant declines in cellulolytic activity at subsequent sampling events. Combining these data with observations of mortality in higher cadmium treatments suggests that impairment of DNA structural integrity and reduced digestive enzyme activity may indicate metal induced stress in clams.

Arch Environ Contam Toxicol 40(4): 497 504, ISSN: 0090 4341. NAL call no: TD172.A7 Abstract: The Dreissena Monitor is a biological early warning system for the continuous monitoring of river water quality, based on the valve movements of two groups of 42 zebra mussels (Dreissena polymorpha). Laboratory experiments with Cd, PCP, and 2 chloro 4 nitro aniline were conducted in combination with suspended particles (a mixture of stinging nettle powder, bentonite, and quartz powder). An increase of suspended particles up to a nominal concentration of 540 mg/L within 5 min did not evoke any reactions by the mussels significantly different from normal. The distribution between water and solids was analyzed for Cd and 2 chloro 4 nitroaniline, with the result that the former quickly adsorbed to the particles, whereas the latter did not bind to the particles at all. The behavior of the zebra mussels revealed that the detection of 2 chloro 4 nitro aniline was not affected by the presence of suspended matter. In the cases of Cd and PCP, D. polymorpha was able to detect these substances when they were particle associated at least as well or better as when they were dissolved in the water. The results are discussed with respect to the physiology of the organisms and the bioavailability of toxicants, as well as to the consequences these results may have

  • 249 Heliciculture As a Tool for Rural Development In
    HELICICULTURE AS A TOOL FOR RURAL DEVELOPMENT IN SOUTHERN TRANSYLVANIA 1 2 VOICHITA GHEOCA , LETI ȚIA OPREAN 1“Lucian Blaga” University of Sibiu, Faculty of Sciences, 2“Lucian Blaga” University of Sibiu, Faculty of Agricultural Sciences, Food Industry and Environmental Protection , 5-7 Dr. I Ra ţiu St., RO – 550012, Sibiu, Romania [email protected] ABSTRACT In Romania there is no tradition as regards the consumption of snails. After several decades of land snails populations’ exploitation for international trade, in the last decade the farming of edible snails has evolved in Romania. The expansion of this practice was encouraged by the SAPARD Program and several foreign companies, promising a quick and easily obtained benefit. About 650 snail farms were established in Romania between the years 2004-2008, most of them using the Italian method, with Helix aspersa in pastures. However, this method had proved its deficiency in the given environmental conditions, leading to high mortality rates. An autochthonous method was developed using H. pomatia , applied by farmers organized in a cooperative, and which have invested in their own processing factory in southern Transylvania, aiming to obtain valuable biologic products. Both the individual farmers and the cooperative were not able to sustain the losses registered during the first years, and find a market for their products, a situation that lead to the collapse of heliciculture in Romania. Despite the unfortunate experience, this new agricultural activity has the potential of a profitable practice in Romania, and especially in Transylvania, not just due to the demand of the European market, but also to the climatic conditions, which make possible the snail farming.

    Series «Medicine». Issue 39 Fundamental researches UDC: 617.3:57.089.67:539.3 DOI: 10.26565/2313-6693-2020-39-01 NEUROMECHANICAL CHARACTERIZATION OF BRAIN DAMAGE IN RESPONSE TO HEAD IMPACT AND PATHOLOGICAL CHANGES Zolochevsky O. O., Martynenko O. V. Traumatic injuries to the central nervous system (brain and spinal cord) have received special attention because of their devastating socio-economical cost. Functional and morphological damage of brain is the most intricate phenomenon in the body. It is the major cause of disability and death. The paper involves constitutive modeling and computational investigations towards an understanding the mechanical and functional failure of brain due to the traumatic (head impact) and pathological (brain tumor) events within the framework of continuum damage mechanics of brain. Development of brain damage has been analyzed at the organ scale with the whole brain, tissue scale with white and gray tissue, and cellular scale with an individual neuron. The mechanisms of neurodamage growth have been specified in response to head impact and brain tumor. Swelling due to electrical activity of nervous cells under electrophysiological impairments, and elastoplastic deformation and creep under mechanical loading of the brain have been analyzed. The constitutive laws of neuromechanical behavior at large strains have been developed, and tension-compression asymmetry, as well as, initial anisotropy of brain tissue was taken into account. Implementation details of the integrated neuromechanical constitutive model including the Hodgkin-Huxley model for voltage into ABAQUS, ANSYS and in-house developed software have been considered in a form of the computer-based structural modeling tools for analyzing stress distributions over time in healthy and diseased brains, for neurodamage analysis and for lifetime predictions of diseased brains.

Simple Summary: This study’s goal was a thorough analysis and a detailed characterization of commercial snail farms in Greece, considering the unstructured development of the snail-farming sector over recent years. Additionally, the characterization of snail farms in Greece could help Southern European countries improve heliciculture. This study classifies 29 farms in five snail farming systems: elevated sections (7%), net-covered greenhouse (38%), a mixed system with a net-covered greenhouse (10%), open field (38%), and mixed system with an open field (7%). Results showed the impact of various parameters (farming system, region, equipment, and facilities) on annual production. Snail farms were dispersed in six different regions (Thrace, Central Macedonia, West Macedonia, Thessaly, Western Greece, and the Attica Islands). The location affected productivity, but also influenced the duration of operation during an annual cycle. Abstract: In this study, the structural and management characteristics of snail farms in Greece were analyzed to maximize sustainable food production. Objectives, such as the classification of farming systems and assessing the effects of various annual production parameters, were investigated.
