Abstract:
AbstractLaboratory assays and field surveys showed that Ascosphaera larvis (Bissett) is a pathogen of alfalfa leafcutting bee larvae, capable of causing high mortality in commercial populations. In one population, over 21% of bees were found to be infected by A. larvis. However, overall levels of the disease are low and it is unlikely that this pathogen poses an immediate threat to commercial leafcutting bee populations in Canada. The LD50 was determined to be 1.9 × 105 spores/bee. Elevated levels of CO2 are required for in vitro spore germination. The disease can easily be diagnosed within bee cells by X-ray radiography, thereby enabling disease levels to be monitored using conventional methods utilized by the industry to monitor leafcutting bee quality.

Dans cet article, nous présentons des caractéristiques du rostre faciles à identifier, permettant la différenciation, à faible grossissement, des sexes de charançons perceurs de tiges vivants. Ces caractéristiques peuvent être utilisées par des travailleurs possédant une formation minimale afin d'identifier correctement le sexe des charançons. Ceci permettra donc une détermination rapide de la proportion des sexes des populations sur le terrain, améliorant ainsi les délais de capture, puis de lâchers.

Foram avaliadas quatro doses de EP TC + R 25 78 8 aplicado em pré-plantio incorporado: 0,0; 1,6; 3,2 e 4,8 kg/ha por quatro doses dediuron : 0,0 ; 0,8 ; 1,2 e 1,6 kg/ha, em quatro repetições. O EPTC + R25788 apresentou bom controle das plantas de tiririca quando aplicado nas maiores doses, principalmente na ausência do diuron. As maiores doses de EPTC + R 25788 aplicadas isoladamente, apresentaram significativos aumentos na população de plantas de folhas largas. As maiores doses de diuron promoveram melhor controle das plantas de folhas largas, na presença das maiores doses de EPTC + R 25788. A combinação das maiores doses dos herbicidas não refletiram em maiores produções. A maior produção de batata-doce ocorreu quando se aplicou 6 L/ha de Eradicane e 1,32 kg/ha de Karmex 800.

AbstractThe effect of light intensity and wind speed on the body temperature of larvae and adults of the Colorado potato beetle (Leptinotarsa decemlineata (Say)) was studied in the laboratory. At a light intensity of 0.95 kW m−2 and without wind, the body temperature of larvae and adults was respectively 9.3 and 18.2 °C higher than air temperature. The temperature difference between the body temperature of larvae and adults and the air temperature increased linearly with an increase in light intensity. Wind speed had an important effect on the rate of increase of the body temperature as a function of light intensity in both larvae and adults. Our results demonstrated that the energy balance of larvae and adults differs.

RésuméUne nouvelle définition des sous-genres de Dercylus Castelnau, 1832, est proposée, et leur synonymie est clarifiée. Quatre sous-genres sont retenus : Dercylus s.str., Eurydercylus, subgen.nov. (espèce-type : Dercylus tenebricosus La Ferté-Sénectère, 1851), Asporina Castelnau, 1835, et Licinodercylus Kuntzen, 1912. Dercylodes Chaudoir, 1883, et Pterodercylus Kuntzen, 1912, sont considérés comme des synonymes de Dercylus s.str. Le nom Licinodercylus Kuntzen, 1912, remplace Physomerus Chaudoir, 1883, homonyme plus récent de trois autres noms de genre. Les 14 espèces aujourd’hui connues du sous-genre Licinodercylus font ensuite l’objet d’une révision systématique. Onze d’entre elles sont des espèces nouvelles : Dercylus (Licinodercylus) franiai Moret, D. onorei Moret, D. orbiculatus Moret, D. praepilatus Moret, D. screator Moret, D. davidsoni Moret, D. granifer Moret, D. nodosus Moret, D. gaujoni Moret, D. gibber Moret et D. mathani Moret. La larve de Dercylus (Licinodercylus) orbiculatus sp.nov. est décrite, et les affinités phylogénétiques des Dercylini sont discutées. On présente enfin les informations disponibles concernant l’écologie et la répartition biogéographique des Licinodercylus de l’Ecuador, et des hypothèses sont proposées sur les modalités de leur spéciation.

Abstract:
Dans de nombreux pays, l’aquaculture de pectinidés dépend aujourd’hui du succès de la production contrôlée de juvéniles. Néanmoins, les fortes variations des taux d’éclosion des oeufs et de la survie larvaire, enregistrées à ce jour, rendent cette production imprévisible. Les élevages larvaires en flux ouvert de coquilles Saint-Jacques (Pecten maximus) ont été développés en Norvège et présentent des résultats prometteurs. Malheureusement, les rendements de production encore faibles et l’impossibilité de travailler à fortes densités restent un frein majeur au développement de cette technique. En France, une technique en flux-ouvert, en petit volume (5 L), et à forte densité (≤ 300 larves mL-1) a été développée pour les ostréidés. Des expériences préliminaires visant à décliner ce système d’élevage aux larves de P. maximus se sont avérées infructueuses : retard de croissance et forte mortalité en quelques jours. Il est reconnu que les larves de pectinidés doivent faire face à des contraintes diverses en écloserie : bactériologiques, physiologiques et environnementales. Elles sont également plus sensibles que les larves des autres espèces de bivalves comme par exemple l’huître japonaise (Crassostrea gigas). Il apparait donc nécessaire aujourd’hui d’identifier plus clairement l’origine des phénomènes perturbant le bon développement des larves en flux ouvert afin d’améliorer la qualité des élevages et les rendements larvaires. Grâce à l’étude et à la compréhension des mécanismes physiologiques impliqués dans la lutte contre le stress des larves de P. maximus en flux ouvert, ce projet de doctorat donne des clés permettant d’améliorer cette technique d’élevage tout en limitant l’utilisation de produits chimiques en milieu contrôlé
In many countries, aquaculture of pectinids depends on the success of artificial spat production in hatchery. This production is always unpredictable due to the variability of hatching rate and larval survival. Flow-through larval rearing systems were developed in Norway for the King scallop Pecten maximus and showed promising results. Unfortunately the system needs to be optimized since the larval yields and the densities used are still relatively low. In France, a small-scale (5 L) and high-density (≤ 300 larva mL-1) flow-through larval rearing system was successfully developed for oysters. First trials in such system and in similar conditions with P.maximus failed as we registered slower growth and high mortality rate in only a few days. It is known that pectinids larvae are more sensitive to environmental conditions than the oyster Crassostrea gigas, for example.Nowadays, it is important to identify and to understand the phenomena disturbing larval development in flowthrough system to improve larval quality and production yields. This doctoral project provided some indications how improving P. maximus flowthrough rearing system while limiting the use of antibiotic through a better understanding the physiological mechanisms involved in the larval response to a stressful environment

Abstract:
D’après le dernier rapport du groupe d'experts intergouvernemental sur l'évolution du climat (GIEC), le réchauffement climatique devrait se poursuivre au cours du siècle prochain. La température atmosphérique moyenne pourrait augmenter de 0,3°C à 4,8°C avec des valeurs extrêmes allant de 1°C à 6°C en 2100. Ces changements de température auront des conséquences directes et indirectes sur l’ensemble de la biodiversité et plus particulièrement sur les poissons qui sont des animaux poïkilothermes. Dans cette étude, trois espèces ont été choisies en prenant en compte leur stratégie de reproduction et leur différence de tolérance thermique : la truite commune (Salmo trutta), le brochet (Esox lucius) et la carpe commune (Cyprinus carpio). Nous avons, pour chacune des trois espèces, appliqué les mêmes différences de température par rapport à leur température de référence (-4, -2, Tref, +2, +4°C) et étudié les effets sur la survie et le développement des embryons et des larves au cours de l’ensemble de la période d’alimentation endogène. Ce travail a confirmé la loi générale de l’impact de la température sur la période d’incubation (Q10 ~3). La truite commune montre une forte diminution de sa survie lors d’une augmentation de quatre degrés, néanmoins les larves survivantes sont plus grandes et ont un contenu énergétique plus important. La survie des larves de brochet augmente avec la température, ces larves sont les plus grandes et leur contenu énergétique est plus important à la température la plus élevée. La survie de la carpe n’est pas affectée par la température ; néanmoins les larves élevées à basse température sont les plus petites et présentent un faible contenu énergétique. Les résultats de survie pour les premiers stades de vie sont en concordance avec les modélisations des aires de répartition actuelle. Dans le futur, la prise en compte de la niche thermique théorique des premiers stades de vie pourrait permettre d’affiner les prévisions des aires de répartition
According to the latest report of the Intergovernmental Panel on Climate Change (IPCC), global warming is expected to continue over the next century, the average temperature could increase by 0.3 ° C to 4.8 ° C with extreme values ranging from 1 ° C to 6 ° C by 2100. These temperature changes will have direct and indirect consequences on the overall biodiversity and specifically fish which are poikilotherms. In this study three species were selected taking into account their reproductive strategy and their thermal tolerance: brown trout (Salmo trutta), pike (Esox lucius) and common carp (Cyprinus carpio). We have applied for all three species the same temperature range of from their referential temperature (-4, -2, Tref °C, +2, + 4 ° C). To carry out this study, we investigated biological traits related to survival and development during the endogenous feeding period. This work confirmed the general law of the impact of temperature during incubation phase (Q10 ~ 3). For brown trout, the results show a collapse of its population with an increase of four degrees; nevertheless surviving larvae were the longest and had a more energetic content. The survival rate of pike larvae increased when temperature increased, these larvae were the longest and the had more energetic content. The survival of the carp was not affected by temperature; nevertheless, at the lowest temperature (16°C), the larvae were smaller and had a lower energetic content. The survival results for the early stages of life are an agreement with the current distribution models. In view of this study the theoretical thermal niche species of early live stage should be undertaken to continue to refine prediction models from range

Abstract:
The phylogeny of land plants, especially angiosperms, has been perplexing scientists for more than 125 years. The aim of this study was to help elucidate unanswered phylogenetic issues using rpb1 genes from twenty-six land plant species (8 gymnosperm species, 17 angiosperm species and Psilotum, a fernally, as the outgroup). The sixteen rpb1 genes which were sequenced in this study had very similar lengths and contained no base compositional bias. Synonymous substitutions of rpb1 sequences were saturated when compared to the outgroup. The third codon positions of these genes contained misleading phylogenetic information. The topology of trees based on first and second codon positions were in line with that of protein trees. Both angiosperms and gymnosperms were monophyletic. Amborella was found at the base of the angiosperm tree, followed by Nymphae, then Illicium. These data rejected the anthophyte hypothesis, weakly supported the gnepine hypothesis, but did not resolve the interrelationship among eumagnoliids and eudicots. rpb1 genes were combined with the 18S ribosomal RNA gene and chloroplast atpB and rbcL genes to obtain more robust phylogenies. This combined data set produced a topology similar to that of the first and second positions of rpb1 genes except that they better resolved the interrelationship among eumagnoliids and eudicots. We conclude that our rpb1 sequences evolve too slowly to provide enough phylogenetic information to fully resolve the phylogeny of seed plants and that other gene sequences will need to be added to these data sets to obtain a well-resolved phylogenetic tree of seed plants.

Abstract:
This study investigates the factors affecting larval and postlarval survival and growth of some de capod crustaceans with special emphasis on diets. Investigations were concentrated on the influence o live and artificial diets on larval growth, survival, development and trypsM activity of a cominerciall, important marine penaeid shrimp Penaeus indicus and a freshwater prawn Macrobrachium rosenber gij. In addition, feeding behaviour, gastroevacuation time, trypsM activity of other decapod species wen also studied. Live mixed microalgae Tetraselmis chuii and Skeletonema costatum at 60-70 cells PI-1 promote( highest larval survival, fastest growth and development in P. indicus in comparison to single algal spe cies. Rhinomonas reticulata neither alone nor in combination with other algal species was suitable a! food for the shrimp larvae, A water salinity (S) of 25 ppt was optimal for larval and postlarval cultun of this penaeid species. Postlarvae (PL) of P. indicus reared at lower salinities between PL7 and PL& (20-30 ppt) had a significantly (P<0.05) higher survival and a better growth than those at higher wate salinities. Early PL resisted sudden salinity change of 10 ppt, but required an adaptation period fo greater salinity changes, 10 ppt S was lethal to animals at around PL40-45. A free-living nematode Panagrellus redivivus was found to be a suitable alternative for live algai and Artemia in the culture of P. indicus. The nematodes gave good survival, but lower growth than al gaelArtemia from PZI to PLI. Larval growth and survival were significantly improved when the larvai were fed on either nematodes plus algal co-feeds or liPid-enriched nematodes. Pigmented- (astaxanthin nematodes also improved survival and colour of P. indicus larvae in comparison to non-pigmented ones Conventional live diets were also completely replaced using microencapsulated diets (MED) fo the culture of P. indicus, Like the nematodes, MED as a sole feed resulted In lower survival, slowe growth and development in comparison to algaelArtemia. Addition of 15 cells gl-1 frozen algae signifi cantly improved growth and survival during larval development. The larvae fed MED plus algal co feeds had significantly (P<0.05) higher trypsm activity than those fed MED as a sole feed. Similarly provision of 15 cells gl-' algae with nematodes for only 24h or 48h resulted in significant increase H trypsin activity and improved survival and growth to levels comparable to those obtained from al gaelArtemia. It appears that the presence of an algal diet is necessary to induce larval trypsin activity Mi P. indicus at early protozoeal stages, but algae do not influence trypsin at mysts stages. Results sugges that both nematodes and formulated diets lack gut enzyme stimulants and are less digestible than al gaelArtemia diets. When freeze-dried algal materials were incorporated into MED, it was found tha algal substances which trigger larval digestive enzymes were retained within the capsules. Whether thi will improve growth and survival of penaeid larvae remains to be examined. In contrast to penaeid larvae, a complete replacement of live Artemia with nematodes or artificia diets was not possible for the culture of caridean M rosenbergii and PaIdemon elegans larvae. Fo both species, only a partial replacement was achieved from Z4/5 to metamorphosis by using formulateA diets. It was found that these larvae have very low trypsin activity levels between ZI and Z4/5, but th, levels increase sharply afterwards, coinciding with a vast increase in the hepatopancreas. This sharl increase in digestive enzyme activities and longer food retention time enable these larvae to survive oj less digestible formulated diets. A comparison of specific trypsin activity in several larval decapod crustaceans shows a pattein with high levels in herbivores, low levels in carnivores and intermediate levels M omnivores. Herbivor penaeid larvae (P. indicus) and copepods (Temora longicornis and Centropages typicus) rely on hig digestive enzyme activities to extract nutrients from less digestible algae, whereas carnivorous larvaE the lobsters (Homarus gammarus and Nephrops norvegicus) and carideans (M. rosenbergii and .1 elegans) have limited enzymatic capacity and hence require large and easily digestible prey, but rests long starvation periods. Omnivorous mysis penaeid larvae and Carcinus maenas have intermediat levels of digestive enzymes and are able to transfer from herbivorous to omnivorous feeding. To datE only decapod larvae which show high trypsm activity can be successfidly reared to metamorphosis o: formulated feeds. Inclusion of algal material, as a gut enzyme stimulant, for penaeid protozoeal stage and pre-digested ingredients for later stages into feeds are proposed.

Abstract:
During preliminary research on cobia (Rachycentron canadum, L.) it became increasingly clear that more in-depth information was required to provide enabling techniques for the cobia aquaculture industry to develop more rapidly. A unifying theme in many of the more important issues facing cobia aquaculture is nutrition. This led to nutritional investigations with larval and juvenile fish highlighting the impacts of dietary ingredients on animal performance. Indeed, nutrition can be viewed as a central lever of action through which many aspects of the physiology and the environmental (water) quality of the animal can be controlled. The first project focused on studying the larval development of cobia, a fish species highly suitable for aquaculture for which the industry is nascent. I described the time-course of development of external sensory organs, gut morphology and relevant digestive enzymes under controlled conditions using electron microscopy, histology and spectrophotometric assays. The developmental sequence of larval cobia could be separated in two phases, with a transition period between 12 and 14 days post hatch (dph). This transition is characterized by the formation of the intestinal loop, the establishment of basic cranial neuromast configuration, leading to the initiation of the onset of pancreatic enzymes and the increase of growth rate. In addition, the effects of dietary taurine supplementation and incorporation of mannan oligosaccharides (MOS) into live feeds on cobia larvae development was examined. Fish fed supplementary MOS did not grow faster but displayed higher microvilli length and density. In addition, MOS-fed fish were more resistant to salinity stress. The dietary supplementation of taurine resulted in a dramatic increase in survival, growth and development rates, and enzymatic activities. The second project aimed at refining cobia juvenile nutrition, assessing fish meal and fish oil replacements. Novel sources, including soy protein and oil, were investigated with and without amino acid and MOS supplementations, yielding promising results. Indeed, both fish meal and fish oil were replaced completely and successfully in feeds for juvenile cobia. In addition, novel ingredients (e.g. marine algae meals and soy protein concentrate) were identified to effectively achieve such replacement. The third and last project dealt with nutrient-gene interactions, specifically centering attention on immunostimulants for which the underlying mechanisms of action remain poorly characterized. Here, dietary MOS, nucleotides and selenomethionine (Se-met) were offered to zebrafish whose transcriptome was analyzed by microarray. The immune system, humoral or cellular, innate or adaptive, exhibited different patterns of response according to the immunostimulating nutrient used. In addition, various genes involved in cell cycle and cytokinesis were concomitantly expressed. An intriguing observation related to the insulinomimetic effect of Se-met. In other words, Se-met impacted pathways normally regulated by insulin, such as the MAPK and PI3K pathways. Some Insulin-like Growth Factors (IGF) and IGF bindgin proteins were up-regulated. Additional research is however necessary prior to advocating for the use of these additives, in order to further investigate their respective pros and cons.

Abstract:
Although platelets are small and simple in shape, they are complicated in their physiologhy. Their alpha granules and dense bodies secrete a large number of agents that are involved in haemostasis, and the glycoproteins on their surfaces form the linkages with proteins like fibrinogen, fibronectin, collagen and von Willebrand factor that are necessary for adhesion and aggregation (Frojmovic, 1998). Diseases such as heart attack (Meade, 1992), stroke (Harker, 1998) and eclampsia (Schindler et al., 1990), can be the result of pathologies in platelets. Although devices have been recently developed to diagnose platelet function (Nicholson et al., 1998), there is still a need for devices that can examine the multiple factors of platelet physiology that affect thrombus formation. Because fluid shear is a key factor in platelet adhesion and aggregation (Colantuoni et al., 1977), it is necessary to test platelet function under conditions of flow. Also, because of the large number of adhesion receptors and secreted agents that make up a platelet’s physiology, a complete diagnosis of platelet function should be performed on a variety of substrates.

Abstract:
Despite half a century of use, mechanical heart valves still require further research to reduce the non-physiologic nature of the flow field, which is the source of potential medical complications, of which the most serious complication is thrombus formation [1]. In the systolic phase of the flow, excessive fluid stresses are generated by the non-physiologic flow patterns [2, 3]. In the closed valve position, a large pressure gradient is imposed across the device which leads to the generation of strong and damaging small-scale leakage flows that entrain platelets such that they are exposed to elevated stresses for excessive time durations [4–6].

Abstract:
Monophasic action potentials (MAPs) have long been used as a means to study the focal electrical activity of the myocardium. [1, 2] Upon the application of adequate contact force, the signals provide important insights into focal depolarization and repolarization, activation timing, and focal arrhythmic behaviors. [3–6] Within our laboratory we have developed an isolated physiologic, four-chamber working, large mammalian heart model (the Visible Heart® methodology) to study cardiac devices and their interactions with the myocardium. [7] Through the use of a modified Krebs-Henseleit buffer, we can uniquely visualize the device-tissue interface: in this study, the placement of catheters. The purpose of this study was two-fold. First, we demonstrated the long term stability of MAP recordings in an in situ swine model. Second, we showed the relationship between MAPs recorded from in vitro and in situ preparations of each specimen.

Abstract:
In Vitro models are being used as a bridge between animal and human studies. Being able to reproduce specific tissue-like structures, functions and responses in a way that is more physiologically relevant allows for huge advantages for tissue engineering, pharmaco-toxicology and food research. These systems are not designed to be directly implanted into patients, but can be used to study human tissue physiology and pathophysiology in vitro. In vitro models are based on human cells, which can capture the responses of the human body, particularly those that are species specific. Models of tissues and organs can give enhanced predictive power, particularly for large-scale screening assays and to understand complex disease pathology.

Abstract:
Tissue engineered pulmonary valves (TEPV) represent a conceptually appealing alternative to current non-viable prosthetic valves and valved conduits for the repair of congenital or acquired lesions in pediatric patients. In addition to the identification of clinically feasible cell sources, engineered soft tissues such as the TEPV require scaffolds with anisotropic mechanical properties that undergo large deformations (not possible with current PGA/PLLA non-wovens) coupled with controllable biodegradative and cell-adhesive characteristics. Electrospun PEUU (ES-PEUU) scaffolds have been produced with tensile biaxial mechanical properties remarkably similar to the native pulmonary valve (Fig. 1-a), including the ability to undergo large physiologic strains and exhibit pronounced mechanical anisotropy. Moreover, a novel cell micro-integration technique has been developed that allows for successful cell integration directly into the scaffolds at the time of fabrication, eliminating cellular penetration problems. These encouraging results suggest that ES-PEUU scaffolds micro-integrated with the appropriate cells and can serve as successful TEPV scaffolds. In the present study, we conducted a finite element based analysis of TEPV leaflets (Fig. 1-b) under quasi-static transvalvular pressure to demonstrate the impact of ES-PEUU mechanical anisotropy on scaffold strain distributions.

Abstract:
Cutting edge computational tools are an important component of the future of tasks such as surgical planning of mitral valve repair and the design and evaluation of prosthetic valves. For example, despite half a century of use, mechanical heart valves still require further research to reduce the non-physiologic nature of the flow field, which is the source of potential medical complications, of which the most serious complication is thrombus formation [1]. In fact, there is still a lack of consensus in the literature about which flow pathologies are the most damaging to blood elements [2, 3]. Much computational work has been performed examining the flow around mechanical heart valve devices [4, 5], but because the emphasis has been on correct valve motion and not fine structure detail, only the largest features have been adequately resolved and the forward flow structures are allowed to dissipate on stretched meshes such that the features may not lead to the correct fine structure state as directionality of blood flow changes during the cardiac cycle.

Full text
Abstract:
Glabrous (hairless) skin found on the hands, feet, face, and ears is a unique component of the thermoregulatory system. Its anatomy and control physiology differ markedly from those of the rest of the skin. Glabrous regions contain vascular networks capable of supporting large blood flows due to the presence of highly tortuous and densely packed arteriovenous anastomoses (AVAs) and associated venous collecting networks [1]. When dilated, these vessels bring large volumes of blood close to the body surface where they function as highly efficient heat exchangers. Furthermore, the manner in which this blood flow is controlled is very unique, exhibiting, for example, rapid and high-magnitude responses, as well as a greater sensitivity to central core signals [1]. In this light, glabrous skin is an important but often overlooked tool the body uses to rapidly and finely adjust energy balance to maintain thermal equilibrium.

Abstract:
At present, antihemophilic factor concentrates available for hemophilia A therapy raise some problems :- weak recovery of FVIIIC (20 to 25%)- specific activity generaly lower than 5IU/mg- loss of a large part of the von Willebrand factor, carrier of the FVIIIC- necessity to inactivate viral contaminants by treatments which induce a decrease in FVIII recovery. To solve these difficulties, an immunopurification process has been developed directly from plasma. A mouse monoclonal antibody (MAb) toward vWF, able to bind the FVIII/vWF complex under physiologic conditions and to release it in a suitable elution buffer preserving the FVIIIC activity has been selected. MAb coupling chemistry on gel beads has been optimised. The immunopurification process developed allows to treat 12 to 19 Liters of plasma with one gram of antibody in each cycle (i.e. 6h.). Immunoadsorbant can be used during 10 cycles with standard quality plasma and with an average recovery of 50% for FVIIIC. This process warrants an important elimination of contaminant virus (104 for HBs) an a release of the mouse MAb in purified FVIII lower than 10-9 M . These properties could justify an industrial application of this immunopurification process to produce therapeutic hemophilia A fractions.

Abstract:
The temporomandibular joint (TMJ) is a load bearing joint with unique articular structure. The TMJ disc, a fibrocartilaginous tissue, is a major component of jaw function by serving stress distribution and lubrication in the joint. The TMJ disc pathophysiology, such as disc derangement and degeneration, is central to many TMJ disorders affecting a large population. It is generally believed that pathological mechanical loading, such as sustained mechanical loading in jaw clenching and traumatic impact, is the leading cause of TMJ disc derangement [1]. However, the exact mechanism, especially at the cellular level, has not been established. TMJ disc cells, fibrochondrocyte-like cells, respond to chemical and mechanical signals and regulate the physiology and pathology of the disc. However, little is known of the cellular mechanical properties in TMJ disc. The objective of this study is to determine the mechanical properties of a single TMJ disc cell using atomic force microscopy (AFM).
