The present paper proposes an account of my research on human and veterinary medicine in Graeco-Roman and Byzantine Egypt, undertaken since 2008 at the CEDOPAL at the University of Liège. This research focuses on literary papyri, particularly on the Anonymus Londiniensis (Hermopolis?, 2d half of the Ist century A.D.), the longest known Greek medical papyrus, as well as on documentary fragments, far more numerous than their literary counterparts, of which several categories have been studied in my PhD dissertation defended in Liège in March 2015.

Continuous glucose monitoring (CGM) devices can measure blood glucose levels through interstitial measurements almost continuously (1-5min sampling period). However, they are not as accurate as glucose readings from blood measurements. The relation between tissue and blood glucose is dynamic and the sensor signal can degrade over time. In addition, CGM readings contains high frequency noise and can drift between measurements. However, maintaining continuous glucose monitoring has the potential to improve the level of glycemic control achieved and reduce nurse workload. For this purpose, a simple model was designed and tested to see the effect of inherent CGM error on the insulin therapy protocol, STAR (Stochastic TARgeted). An error model was generated from 9 patients that had one Guardian Real-Time CGM device (Medtronic Minimed, Northridge, CA, USA) inserted into their abdomen as part of an observation trial assesing the accuracy of CGM measurements compared to a blood gas analyser and glucometer readings. A resulting error model was then used to simulate the outcomes if the STAR protocol was guided by CGM values on 183 virtual patients. CGM alarms for hyper- and hypo-glycaemic region were included to improve patient safety acting as 'guardrails'. The STAR CGM protocol gave good performance and reduced workload by ∼50%, reducing the number of measurements per day per patient from 13 to 7. The number of hypoglycaemic events increased compared to the current STAR from 0.03% <2.2mmol/L to 0.32%. However, in comparison to other published protocols it is still a very low level of hypoglycaemia and less than clinically acceptable value of 5% <4.0mmol/L. More importantly this study shows great promise for the future of CGM and their use in clinic. With the a newer generation of sensors, specifically designed for the ICU, promising less noise and drift suggesting that a reduced nurse workload without compromising safety or performance is with in reach.? © 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.

The common hippopotamus (Hippopotamus amphibius L.) is part of the animal species endangered because of multiple human pressures. Monitoring of species for conservation is then essential, and the development of census protocols has to be chased. UAV technology is considering as one of the new perspectives for wildlife survey. Indeed, this technique has many advantages but its main drawback is the generation of a huge amount of data to handle. This study aims at developing an algorithm for automatic count of hippos, by exploiting thermal infrared aerial images acquired from UAV. This attempt is the first known for automatic detection of this species. Images taken at several flight heights can be used as inputs of the algorithm, ranging from 38 to 155 meters above ground level. A Graphical User Interface has been created in order to facilitate the use of the application. Three categories of animals have been defined following their position in water. The mean error of automatic counts compared with manual delineations is +2.3% and shows that the estimation is unbiased. Those results show great perspectives for the use of the algorithm in populations monitoring after some technical improvements and the elaboration of statistically robust inventories protocols.

This paper presents recent improvements of our new solar concentrator design for space application. The concentrator is based on a combination of a diffraction grating (blazed or lamellar) coupled with a Fresnel lens. Thanks to this diffractive/refractive combination, this optical element splits spatially and spectrally the light and focus approximately respectively visible light and IR light onto electrically independent specific cells. It avoid the use of MJs cells and then also their limitations like current matching and lattice matching conditions, leading theoretically to a more tolerant system. The concept is reminded, with recent optimizations, ideal and more realistic results, and the description of an experimental realization highlighting the feasibility of the concept and the closeness of theoretical and experimental results.

Comet C/2012 S1 (ISON) was one of the Oort cloud comets and dynamically new. This comet was broken at its perihelion passage on UT 2013 November 28.1 (at Rh ~ 17 solar radius). We observed the comet C/2012 S1 (ISON) on UT 2013 November 15 with the High Dispersion Spectrograph (HDS) mounted on the Subaru Telescope atop Mauna Kea, Hawaii. Its heliocentric and geocentric distances were 0.601 and 0.898 AU, respectively. We selected the slit size of 0”.5 x 9”.0 on the sky to achieve the spectral resolution of R = 72,000 from 550 to 830 nm. The total exposure time of comet C/2012 S1 (ISON) was 1200 seconds. We detected many emission lines caused from radicals (e.g., CN, C2, NH2), ions (H2O+), atoms ([OI] and Na I) and also many unidentified lines in the spectra. We report the (1) the ortho-to-para abundance ratios (OPRs) of water and ammonia estimated from the high-dispersion spectra of H2O+ and NH2, (2) the green-to-red line ratio of forbidden oxygen emissions, (3) the isotopic ratios of C2 (the carbon isotopic ratio from Swan band) and CN (the carbon and nitrogen isotopic ratios from red band), (4) the sodium-to-continuum ratio of comet C/2012 S1 (ISON). </PRE></BODY></HTML> [less ▲]

C/2013 A1 (Siding Spring) is a long period comet discovered by Robert H McNaught at Siding Spring Observatory in Australia on January 3, 2013 at 7.2 au from the Sun. This comet will make a close encounter with Mars on October 19, 2014. At this occasion the comet will be extensively observed both from Earth and from several orbiters around Mars.On September 20, 2013 when the comet was around 5 au from the Sun, we started a monitoring with the TRAPPIST robotic telescope installed at La Silla observatory [1]. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins B, V, Rc, and Ic filters.We observed the comet continuously at least once a week from September 20, 2013 to April 6, 2014 with broad band filters. We then recovered the comet on May 20. At this time we could detect the gas and started the observations with narrow band filters until early November, covering the close approach to Mars and the perihelion passage.We present here our first results about comet Siding Springs. From the images in the broad band filters and in the dust continuum filters we derived A(θ)fρ values [3] and studied the evolution of the comet activity with the heliocentric distance from September 20, 2013 to early November 2014. We could also detect gas since May 20, 2014. We thus derived gas production rates using a Haser model [4]. We present the evolution of gas production rates and gas production rates ratios with the heliocentric distance.Finally, we discuss the dust and gas coma morphology. [less ▲]

TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) is a 60-cm robotic telescope that has been installed in June 2010 at the ESO La Silla Observatory [1]. Operated from Liège (Belgium) it is devoted to the detection and characterisation of exoplanets and to the study of comets and other small bodies in the Solar System. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins filters. We describe here the hardware and the goals of the project. For relatively bright comets (V < 12) we measure several times a week the gaseous production rates (using a Haser model) and the spatial distribution of several species among which OH, NH, CN, C2 and C3 as well as ions like CO+. The dust production rates (Afrho) and color of the dust aredetermined through four dust continuum bands from the UV to the red (UC, BC, GC, RC filters). We will present the dust and gas production rates of the brightest comets observed in 2014: C/2012 K1 (PANSTARRS), C/2014 E2 (Jacques), C/2013 A1 (Siding Springs) and C/2013 V5 (Oukaimeden). Each of these comets have been observed at least once a week for several weeks to several months. Light curves with respect to the heliocentric distance will be presented and discussed.

The aim of this study was to evaluate the physico-chemical stability of Belgian Blue beef packaged under high-oxygen atmosphere as a function of a previous aging technique (wet-aging in vacuum conditions vs. carcass-aging). Two muscles (longissimus dorsi vs. rectus femoris) were studied. After a seven-day wet- or carcass-aging step, muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. Each 14 days, part of these samples was repackaged under modified atmosphere (70 % O2:30 % CO2), and stored during 7 days at +4 °C. The following parameters were evaluated: color, metmyoglobin %, metmyoglobin reducing activity, fat content, fatty acid profile, lipid oxidation, antioxidant enzyme activities and alpha-tocopherol content. The sensitivity of modified atmosphere repacked meat cuts to oxidation was influenced by the conditions of the previous aging period (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage.

Introduction Cancer is a major health problem widespread in elderly, which is inscribed in ageism context1. Negative influence of the vision that older people possess on aging on mental and physical health2 is well established within “normal” aging. Consequently, we can ask ourselves what consequences age stigmas have in the realm of oncogeriatry. Moreover, cancerous patients face pathology-related stigmas because nowadays cancer still conveys a lot of negative representations. Method A group of 120 patients aged of 65 years old and more suffering from cancer (lung, breast or gynecological) will be followed during one year (0-3-6-12 months). Different instruments measuring quality of life, depression, symptoms, etc. are used as well as questions about their vision of aging and of cancer. Clinical parameters (weight, biologicals values, comorbidity…) are recorded too. Currently, we have 63 patients (31 breast cancer, 14 gynecological cancer and 18 lung cancer with distinction between smokers and non-smokers). Our analysis is only on the baseline at this moment, without any distinction between kinds of cancers. Results Double ANOVAs were used to analyze the data. A positive vision of aging is linked to a lower level of depression in comparison to a negative vision of aging (p = .04). Vision of pathology approach significance: less depression when vision is positive (p = .077). Concerning daily functioning (physical, emotional, social...), a positive vision of aging is related to a better functioning (p = .03) whereas vision of pathology has no effect. Eventually, a positive vision of aging and of cancer is related to a better quality of life (respectively p=.02, p=.002). Concerning clinical parameters, no results are observed. Conclusion These first results suggest that the vision patients have themselves of the age and of cancer is in relation with subjective mental and physical health. As we observe influence on vision of aging as well as pathology, we can talk about “double stigmatization”. Needless to say, more studies are needed to analyze the direction of these observation and longitudinal data analysis could bring some answers: is stigmatization provoke a less good mental and physical health or is it because I have health problem that I have a negative vision of aging and of my disease? 1.

Background: Population based studies have shown evident benefit in terms of mortality from screening for Abdominal Aortic Aneurysm (AAA) among men aged over 65. However, recent studies from USA, UK and Sweden suggest a decrease in the prevalence of AAA in the general population. Whether these findings are generalizable for the rest of Europe is unknown. Thus we decided to set up a screening program in order to detect AAA in Liege, Belgium. Material and Methods: During our ongoing study, over a first 3-month period, abdominal aortic ultrasound was performed on 541 participants, (198 women 343 men) to measure the maximal suprarenal and infrarenal aortic outer-outer diameter as well as the maximal diameter of the common iliac arteries. Moreover, we have measured arm and ankle blood pressure in each subject and the clinical characteristics of the patients, were collected. Results: The overall AAA prevalence was 4.62% (n = 25). In female participants aged ≥ 74 years the AAA prevalence amounted 1.01 %. While in male patients aged ≥ 65 years, it rose to 6.71%. Statistical analysis showed that male gender, aging, history of ischemic heart diseases, hyperlipidemia and varicose veins were significantly associated with AAA. Conclusion: Despite a reported declining prevalence of AAA in some recent population-based studies, we found that the prevalence of AAA in Liège population remains high in men aged 65 years or more. The prevalence of AAA seems to vary in different geographical regions. However, we need a larger sample to confirm our preliminary findings. [less ▲]

INTRODUCTION. Renal dysfunction often occurred after liver transplantation. OBJECTIVES. The aim of the study was to determine its incidence and its risk factors in a clinical series at the University Hospital of Liege, Belgium. METHODS. Orthotopic liver transplantations performed from January 2006 until Sep- tember 2012 were retrospectively reviewed (n = 187). Patients, with no renal replacement therapy (RRT) before transplantation were classified in four groups according to their highest creatinine plasma level during the first postoperative week. First group had a cre- atinine level below 12 mg/l, the second group between 12 and 20 mg/l, the third group between 20 and 35 mg/l, and the fourth above 35 mg/l. In addition, patients who needed RRT during the first week after transplantation were also classified in the fourth group. Preoperative and perioperative parameters were tested as risk factors: age, sex, body mass index (BMI), length of hospital preoperative stay, prior bacterial infection within one month, preoperative ascites, preoperative treatment with ß-blocker, converting enzyme inhibitor, or non steroidal antiinflammatory drugs, preoperative creatinine and bilirubine level, postop- erative lactate level, need for postoperative vasopressive drugs, surgical revision, mechanical ventilation for more than 24 h, postoperative peaks in bilirubine and transam- inase levels, postoperative hemoglobin level, amount of perioperative blood transfusions, type of immunosuppression. Univariate and multivariate analysis were performed using logistic ordinal regression method. RESULTS. There were 78 patients in group 1 (41.7 %), 46 in group 2 (24.6 %), 38 in group 3 (20.3 %) and 25 in group 4 (13.4 %). Eighteen patients required RRT: 13 (7 %) during the first week after transplantation (group 4), the 5 others after the first week after transplan- tation (2 in group 1 and 2, and 1 in group 3). There were 7 (3.7 %) early deaths within 28 days after transplantation. Using univariate analysis, the severity of renal dysfunction was correlated with presence of ascites and prior bacterial infection, preoperative bilirubin and creatinine level, need for surgical revision, use of vasopressor, postoperative mechanical ventilation, postoperative bilirubine, transaminase, and hemoglobin levels. The need for transfusion of each type of products also affected renal dysfunction. The ordinal logistic analysis pointed out the BMI (OR = 1.1, p = 0.004), preoperative creatinine level (OR = 11.1, p \ 0.0001), use of vasopressor (OR = 3.31, p = 0.0002), maximal postop- erative bilirubine level (OR = 1.44, p = 0.044) and minimal postoperative hemoglobin level (OR 0.059 p = 0.0005). CONCLUSIONS. More than half of liver transplanted patients experienced some degree of early renal dysfunction after transplantation. Risk factors are preoperative renal dysfunction, and mainly perioperative circulatory instability requiring the use of vasopressor and post- operative anemia. [less ▲]

Purpose: Successful downstaging of hepatocellular carcinoma (HCC) into the Milan criteria (MC) remains a controversial indication for orthotopic liver transplantation (OLT). In Belgium, successful downstaging of HCC is an accepted non-standard- ized exception (NSE) for liver allocation. This NSE group rep- resents a unique cohort to analyse if OLT can be safely offered to patients with those extended allocation criteria. The aim of this study is to compare the overall and recurrence free survival after cadaveric OLT between patients with successful downstaging (MILDOWN) and patients always inside the MC (MILIN) from all Belgian transplant centres. Methods: We ret- rospectively analysed all patients listed for OLT with HCC and underlying cirrhosis between 12/2006 and 12/2011 from all Belgian liver transplant centres. Successful downstaging was defined as bringing a patient who was outside the MC into the MC after locoregional therapy (LRT). Results: Overall 381 patients were listed in Belgium during the study period. Of these, 320 received OLT. 248 were MILIN, 62 were MIL- DOWN and 10 were transplanted outside MC. Downstaging treatment included transarterial chemoembolization (TACE; n=26), radiofrequency (RF; n=9), transarterial radioembolisa- tion (TARE; n=4), resection (n=3), percutaneous ethanol injec- tion (n=2) and a combination of the above-mentioned therapies in 18 cases. In the MILIN group 67.3% received locoregional therapy before transplantation, with no significant differences in the distribution of treatment type compared to the MIL- DOWN group. At listing there were no significant differences between the MILIN and MILDOWN group for age, gender and underlying liver disease. Median time on waiting list between the two groups was similar (120 days vs. 115.5 days). Overall survival at 1 year was not significantly different between MILIN and MILDOWN (87.1% vs. 79%; p=0.120). 1.6% of patients were lost to follow-up in both groups. Although not significant, recurrence free survival at 1 year tended to be higher in the MILIN group than in the MILDOWN group (83.9% vs. 74.2%; p=0.073). Conclusion: In this large Belgian multicentre cohort, overall and recurrence free survival at 1 year are not signifi- cantly different between patients who have been downstaged successfully and patients who were always inside the Milan criteria. However, a longer follow up period will define, if the trend of lower survival in the successfully downstaged group becomes significant. Factors associated with HCC recurrence have to be identified.

Multi-Chromatic or spectral Analysis (MCA) of SAR images consists in splitting wide band SAR signals into sub-bands to generate several lower resolution images from a single acquisition. This splitting allows performing a spectral analysis of observed scatterers. Spectral coherence is derived by computing the coherence between sub-images issued from a single SAR acquisition. It was shown that in the presence of a random distribution of surface scatterers, spectral coherence is proportional to sub-band intersection of sub-images. This model is fully verified when observing spectral coherence on open seas areas. If the scatterers distribution departs from this distribution, like for manmade structures, spectral coherence may be preserved to a certain degree. We investigated the spectral coherence to perform vessel detection on a sea background by using spotlight images acquired on the Venice Lagoon. Sea background tends to lead to very low spectral coherence while this latter is preserved on the targeted vessels, even for very small ones. A first analysis shows that all vessels observable in intensity images are easily detected in the spectral coherence images which can be used as a complementary information channel to constrain vessel detection.

In this contribution, the formability of sheet metal cut edges is investigated using damage model.Classical forming limit diagrams are known not to apply properly to the cut edges. However, with mild steels the sheet edges usually behave better than the Forming Limit Diagram prédictions, so this phenomenon has not been given sufficient attention. In contrast, for Advanced High Strengh Steels the cut edges exhibit reduced formability as compared to the plain sheet;this effect is very sensitive to the quality of the cutting process. The current investigation is aimed to evaluate the ability of available damage models to predict this effect on sample applications. The Gurson-Tvergaard-Needleman model is used and the material parameters for a Dual Phase are considered [1]. The effect of the cutting process is described by means of initial fields of equivalent plastic strain and porosity. The geometrical distribution and typical values for these two initial fields are devised based on literature . Numerical simulations of flat notched tensile tests are used within the FE code Abaqus/Explicit to illustrate the impact of the initial fields on the moment and the location of the failure initiation. The influence of the mesh size in the cutting-affected area is also investigated. The hole expansion test and a flat bending test are further simulated to investigate the influence of the cut edge.

True hermaphroditism in horses, is a complex and poorly under- stood disorder of sexual development characterized by the presence of both male and female gonads as separate organs or in a combined structure called ovotestis. A 3-year-old Spanish nullipa- rous mare with a history of stallion behaviour and an abnormal reproductive exam was presented at the Equine Clinic of the University of Li ege. Externally, a small vulva with an enlarged clitoris was observed. Transrectal ultrasonography showed a thin (<1 cm) uterus, leading to a small heterogeneous structure in the normal place of the left ovary. No structure could be identified in the presumed location of the right ovary. Speculum exam was compatible with a vaginal agenesis, as the cervix opened craniad the urethral meatus. Oestradiol, progesterone and testosterone concen- trations were compatible with a stallion’s endocrinology. Gonads were laparoscopically found in the usual location of the ovaries in both flanks and excised. Histopathology of both gonads showed atrophic testicular tissue with hyperplastic Leydig cells. The left gonad also contained ovarian tissue with some scarce primordial follicles. Clitoral enlargement is the first symptom most commonly identified in animals with true hermaphroditism and can be explained by the production of testosterone by the gonads, however, the aetiology of the vaginal agenesis is unknown. True hermaph- roditism in horses is generally related to 64XX syndrome with or without SRY gene translocation (impending karyotyping analysis). After 5 days the mare was discharged from the clinic, and in absence of testosterone the stallion behaviour disappeared in a couple of months. [less ▲]

Investigations on steel thixoforming started in the early 90’s and many developments were carried out, mainly driven by the industrialization of the process. After a series of basic investigations on adapted steels and materials as well as near-net shaping investigations, the issue of mass production raised and thus induced some other challenges mainly on die life and process automation and cycling. High working temperatures and components complexity were then the main locks to mass productions. In most of reported literature, none of the involved research group reached or real production and industrialization criteria. The euro group holds most of these research investigations [1]. We have reported many of these results in previous communications and this paper presents a continuity of what have already been presented. Some advanced tooling materials and solutions are presented and applied to a real complex industrial component. © (2015) Trans Tech Publications, Switzerland. [less ▲]

Precision livestock farming is emerging in the wake of the technological developments in remote sensing and motion monitoring. Tools are developed to allow accurate real time monitoring of the individual cattle behaviour in a quest to improve the management of pastures. Studies have shown the relevancy of accelerometers in the analysis of behaviour using dedicated devices. Accelerometers are located either close to the mouth or jaw of the animal or on its forehead or neck. Records are usually performed at low frequency (<1Hz) and most studies classify behaviours using neuronal networks or multivariate statistical approaches, with little consideration to the animals’ actual movements. Inertial measurement units (IMU) in consumer mobile devices are specifically developed to record accurately user movements. Besides 3D-accelerometer, they can include 3-D rotational speed sensors, 3-D magnetometers and GPS. Optimised power consumption offers significant autonomy. Data directly acquired from the sensors and IMU signals from build-in proprietary algorithms can be recovered using user-friendly low-cost applications. Moreover, mobile devices can store or communicate information by wireless in real time at high frequency. As movements of cattle are in the same range as humans, this study investigates the relevancy of mobile devices IMU signals to discriminate main behaviours of cattle on pasture. [less ▲]

INTRODUCTION. Depression is a common psychopathology characterized by a decrease of the level of behavioural activation (BA) that is the level of engagement in activities. The relationship between depression and BA is well-established in the scientific literature. According to theoretical models of depression, psychopathology is also characterized by biases in five sets of psychological processes (PP): self-image (e.g. self-esteem), negative repetitive thoughts (e.g. ruminative thoughts), experiential avoidance (e.g. mindfulness), environmental satisfaction (e.g. environmental reward observation) and emotional regulation (e.g. distress tolerance). Therefore, the present study aims to identify PP mediating the relationship between depression and the level of BA. In order to reach this objective, a conceptual model is tested. METHOD. 361 adults (x ̅ age=36, σ=15), from clinical and non-clinical settings, fulfilled a series of questionnaires assessing several variables: sociodemographic data, depression, anxiety, level of BA and the above-cited five sets of PP. Covariance structure analysis will be conducted in order to test the conceptual model mentioned above. RESULTS. Some preliminary results are presented. As expected, a negative significant correlation between depression and BA (r=-.66, p<.01) have been highlighted. Negative significant correlation appeared between BA and the measured PP: self-esteem (r=-.27, p<.01), ruminative thinking (r=-.53, p<.01), environmental reward observation (=-.13, p<.05). Positive significant correlations appeared between BA and mindfulness (r=.49, p<.01) and distress tolerance (r=.26, p<.01). DISCUSSION. The preliminary results are in line with our hypotheses. Indeed, the level of BA is negatively linked to PP usually biased in depression such as self-esteem. The mediating role of these PP between depression and the level of BA will be discussed. [less ▲]

Genetic selection programs aiming to mitigate methane (CH4) emissions require the estimation of genetic correlations with other production and economical traits and predicted selection response. CH4 intensity was predicted from Mid-infrared spectra of milk samples from Holstein cows. Genetic correlations between CH4 intensity and milk yield (MY) was -0.68, fat yield (FY) -0.13, protein yield (PY) -0.47, somatic cell score (SCS) 0.07, longevity 0.05, fertility 0.31, body condition score (BCS) 0.17. Adding 25% relative weight on CH4 intensity to the current Walloon selection index, the response to selection would reduce CH4 intensity by 24%, increase MY by 30%, FY by 17%, PY by 29%, SCS by -14%, longevity by 24% but also reduce fertility by 11% and BCS by 13%. In conclusion, environmental traits can be added without jeopardizing production traits, but energy balance related traits have to be protected. [less ▲]

We present the first observations obtained with the L'-band AGPM vortex coronagraph recently installed on LBTI/LMIRCam. The AGPM (Annular Groove Phase Mask) is a vector vortex coronagraph made from diamond subwavelength gratings. It is designed to improve the sensitivity and dynamic range of high-resolution imaging at very small inner working angles, down to 0.09 arcseconds in the case of LBTI/LMIRCam in the L' band. During the first hours on sky, we observed the young A5V star HR8799 with the goal to demonstrate the AGPM performance and assess its relevance for the ongoing LBTI planet survey (LEECH). Preliminary analyses of the data reveal the four known planets clearly at high SNR and provide unprecedented sensitivity limits in the inner planetary system (down to the diffraction limit of 0.09 arcseconds). © 2014 SPIE.

Introduction: The equine suspensory ligament (SL) injuries are an important cause of lameness in horses. Quantification of the relative abundance of the constitutive collagen types is essential to investigate the differences between normal and injured tissues. The aim of this original study was to precisely determine the different collagen ratios both in injured and normal SL. This approach is a rational step towards understanding the intimate mechanisms of SL repair and regeneration at the molecular and histological levels. Methods: Five Warmblood horses with visible signs of injury in only one forelimb SL were selected. Specimens were obtained from the central core of lesions in damaged SLs and from the corresponding regions in other healthy SLs. Collagen types I, III and V were purified by differential salt precipitation after collagen extraction with acetic acid containing pepsin and they were examined by transmission electron microscopy. The bands corresponding to types I, III, and V collagen were assessed by densitometry after SDS-PAGE. SAS software (SAS Institute 2001) was used for all statistical analyses. Results: Based on ultrastructural observations, purified fibers of types I, III, and V collagens have been identified. The relative proportions of type III and type V collagen were significantly higher in the specimens‎ from damaged tissue compared with specimens from normal tissue (P < 0.001). These changes were concomitant with significant decrease in type I collagen in the injured tissue (P < 0.001). Conclusions: Our study showed that after SL injury, the relative abundance of the different collagen types is modified. These changes are the molecular hallmark of a decrease in tissue quality and mechanical properties of the ligament. It lays down the bases of subsequent researches on the tissue regeneration that may lead to the development of new treatment strategies for damaged tissues, particularly in the equine SL injuries.
