Abstract (sommario):
Balekambang Beach is the most visited beach destination in Malang Regency until the end of 2015. One of the invasive pathways of invasive plants is Tourism. The purpose of this study was to identify invasive plant species, diversity and compare the value of the diversity index with abiotic factors.This research method is descriptive with systematic sampling techniques using Belt Transect, and measurements of abiotic factors include edafic factors and climatic micro factors. Invasive alien plant species found in the Balekambang coastal forest are identified as seventeen species namely (Hemighraphis glaucescens), (Oplismenus sp), (Amomum coccineum), (Arenga obtusifolia), (Leucaena leucochephana), (Mimosa sp), (Cassia siamea), (Eupatorium odoratum), (Hyptis capitata), (Cynodon dactylon), (Sida rhombifolia), (Synedrella nudiflora), (Chromolaena odorata), (Leucaena leucochepala), (Mimosa pudica), and (Ruellia tuberosa) with the index value of invasive plant diversity in protected forests and production classified as high compared to mangroves. The results of the diversity index value with abiotic factors showed a positive (+) direction on soil sailinity where the R2 value was 0.5606 or 50%, which means it showed a relationship between soil salinity and an abundance of invasive plants in Balekambang coastal forest area of 50%.

Abstract (sommario):
Ikan invasif menjadi faktor utama penyebab kerentanan ikan endemik di Indonesia dan bahkan menyebabkan kepunahan. Ikan invansif sebagaian besar dimulai dari adanya introduksi ikan hias ke perairan umum, penting untuk melakukan pendataan dalam rangka pengendalian ikan invasif di Indonesia Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis ikan hias yang dijual di Kabupaten Purbalingga dan tingkat ancaman invasifnya.pada penelitian ini pengambilan data dilakukan dengan menggunkan Survei aktif secara purposive dilakukan dengan menggunakan kuesioner kepada toko penjual ikan hias di Kabupaten Purbalingga. Hasil penelitian menunjukkan bahwa ada 21 spesies ikan hias dari 20 yang diperdagangkan yang termasuk dalam kategori berbahaya atau berpotensi invasif. Para penjual ikan hias yang menjadi responden tidak mengetahui bahwa jenis-jenis ikan hias yang mereka jual termasuk invasif dan berpotensi invasif. Hal tersebut menimbulkan risiko tinggi dan bahaya yang serius bagi ekosistem air apa bila tidak di imbangi dengan pengetahuan ikan invasif. Pelepas liaran ikan invasif dapat mempengaruhi keseimbangan ekosistem, menurunkan keanekaragaman hayati, dan bahkan mengancam kelangsungan hidup spesies asli di perairan tersebut. Edukasi tentang bahaya ikan invasif perlu ditingkatkan, tidak hanya pada penjual tetapi juga pada pembeli agar mereka tidak melepaskan ikan tersebut ke perairan umum. Perlu adanya regulasi pemerintah yang ketat pada impor ikan hias dalam rangka mengendalikan ikan invasif di Indonesia, pendataan dan edukasi tentang bahayanya perlu ditingkatkan. Dengan meningkatkan kesadaran tentang bahaya ikan invasif, diharapkan masyarakat dapat mengurangi dampak negatifnya pada ekosistem perairan.Penelitian ini diharapkan dapat memberikan informasi penting bagi para penjual ikan hias dan juga otoritas yang terkait.

Abstract (sommario):
Tumbuhan asing invasif merupakan salah satu ancaman bagi keanekaragaman hayati Indonesia. Tumbuhan ini dapat mengubah ekosistem dengan mendominasi lanskap. Mengingat besarnya dampak yang dapat ditimbulkan oleh invasi tumbuhan di kawasan konservasi, maka perlu dilakukan inventarisasi jenis-jenis tumbuhan yang berpotensi invasif di Taman Nasional Way Kambas (TNWK), sehingga dampak negatif dari invasi akan mudah di cegah. Inventarisasi dilakukan dengan membuat plot analisis vegetasi pada empat tipe vegetasi di TNWK, yaitu vegetasi hutan, vegetasi hutan campuran, vegetasi rawa dan vegetasi alang-alang. Berdasarkan hasil analisis vegetasi, diperoleh 11 jenis tumbuhan berpotensi invasif di TNWK, yaitu Actinoscirpus grossus, Clidemia hirta, Chromolaena odorata, Fimbristylis ovata, Hyptis capitata, Imperata cylindrica, Isachne globosa, Lantana camara, Melaleuca leucadendron, Melastoma malabathricum, dan Mimosa pigra. Invasive alien plant species are a threat to Indonesia's biodiversity. These plants can change ecosystems by dominating landscapes. Given the magnitude of the impact that can be caused by plant invasions in conservation areas, it is necessary to carry out an inventory of potentially invasive plant species in Way Kambas National Park (TNWK), so that the negative impacts of these invasions can be easily prevented. . The inventory was carried out by plotting vegetation analysis on four types of vegetation in TNWK, namely forest vegetation, mixed forest vegetation, swamp vegetation, and alang-alang vegetation. Based on the results of the vegetation analysis, 11 species of plants that have the potential to be invasive in TNWK were found, namely Actinoscirpus grossus, Clidemia hirta, Chromolaena odorata, Fimbristylis ovata, Hyptis capitata, Imperata cylindrica, Isachne globosa, Lantana camara, Melaleuca leucadendron, Melastoma malabathricum, dan Mimosa pigra.

Abstract (sommario):
Invasive fractional flow reserve (FFR) is the gold standard for guiding decision making to identify patients who would benefit from revascularization. Now, computed tomography can also do that by using computational fluid dynamics to calculate fractional flow reserve values from coronary CT angiography image data sets, known as CT-FFR. CT-FFR as an alternative method beside invasive FFR enables the identification of lesion-specific in coronary tree noninvasively. CT-FFR has showed significant improvement in specificity and positive predictive value and decreasing the frequency of using invasive coronary angiography.
Abstrak
Pemeriksaan invasif fractional flow reserve (FFR) adalah standar emas untuk memandu pengambilan keputusan dalam mengidentifikasi pasien apakah yang mendapat manfaat dari revaskularisasi. Sekarang, computed tomography juga dapat melakukannya dengan menggunakan dinamika cairan terkomputasi untuk menghitung fractional flow reserve dari kumpulan data gambar angiografi koroner CT, yang dikenal sebagai CT-FFR. CT-FFR sebagai metode alternatif selain FFR invasif memungkinkan identifikasi spesifik lesi pada koroner secara non-invasif. CT-FFR telah menunjukkan peningkatan yang signifikan pada spesifisitas dan nilai prediksi positif dan penurunan frekuensi penggunaan angiografi koroner invasif.

Mortality rate of invasive candidiasis is still high, approximately 30-70%. Every study has a variety mortality rate depend on study design and sample. There is no data in Indonesia about profile and mortality factors analysis in critically ill patients with invasive candidiasis. Methods. The Study design was cross sectional. We studied 102 hospitalized critically ill patients with invasive candidiasis. The demographic, clinical and laboratory data, the risk factors for invasive candidiasis and the outcome of each patient in 30 days were recorded. An analysis bivariate with chi square or Fisher’s test was carried out to analyse some factors such as age > 60 years old, severe sepsis, APACHE score > 20, respiratory failure, renal failure, delayed antifungal treatment > 72 hours after positive culture, Charlson index score, and ICU or non ICU patients. The logistic regression of multivariate analysis was carried out to identify the most influence of all mortality factors. Results. Among 102 identified sample, the majority was male (52.9%), the median age was 53 years old and the mortality rate was 68,6%. Laboratory candida findings came from blood sample (candidemia) (98.03%), liquor cerebrospinal (1.5%) and retina exudate (1.5%). The most common candida species were candida non albicans especially Candida tropicalis (34.3%) and Candida parapsilosis (34.3%). The risk factors for invasive candidiasis from this study related to underlying disease were sepsis (78.9%), malignancy (42.15%), diabetes mellitus (29.4%) and related to therapy or treatment were the usage of broad spectrum antibiotic (99%), central vein catheter (77.5%), and parenteral nutrition (70.6%). The result from multivariate analysis, severe sepsis (p 0.001, OR 7.7, IK95% 2.4 – 24.7), Ch arlson Index ≥3 (p 0.022, OR 3.5, IK95% 1.2–10.2), and respiratory failure (p 0.066, OR 2.7 IK95% 0.9 – 8.0) were independently associated with mortality. Conclusions. In Cipto Mangunkusumo hospital, most critically ill patients with invasive candidiasis was male, median age was 53 years old, and mortality rate was 68,6%. The most species candida caused infection were Candida tropicalis and Candida parapsilosis. The most risk factors of invasive candidiasis from underlying disease was sepsis and from the treatment was the usage of broad spectrum antibiotic. Severe sepsis, and Charlson index ≥3 were associated with a 30 day mortality in critically ill patients with invasive candidiasis.

Abstract (sommario):
Prognosa angka harapan hidup neonatus tergantung pada berat lahir dan usia kehamilan. Bayi prematur memerlukan proses penyesuaian dari kehidupan di dalam uterus ke luar uterus dan bayi prematur lebih sulit melewati proses adaptasi tersebut dibandingkan dengan bayi normal. Neonatal intensive care unit (NICU) merupakan unit khusus untuk perawatan bayi baru lahir, termasuk bayi prematur yang membutuhkan tindakan resusitasi sampai bayi benar-benar siap beradaptasi dengan lingkungan luar. Kondisi lingkungan di ruang NICU sangat kompleks dan pada umumnya menimbulkan stimulasi berlebihan. Stimulasi berlebihan yang dialami bayi prematur berupa bising, cahaya berlebihan, handling, serta tindakan invasive Perawatan bayi prematur di unit perawatan intensif dapat menimbulkan stimulasi berlebihan bahkan stres fisik pada bayi akibat prosedur invasif yang rutin dilakukan. Studi fenomenologi ini bertujuan untuk mengetahui pengalaman perawat dalam mengambil keputusan untuk pelaksanaan tindakan invasif pada bayi prematur. Partisipan berjumlah 7 orang perawat di ruang perinatologi yang dipilih secara purposive sampling. Hasil penelitian mengidentifikasi tema perilaku etis saat pelaksanaan tindakan invasif antara lain: 1) memenuhi hak kebebasan pasien, 2) memberi manfaat dan meminimalkan bahaya ketidaknyamanan selama prosedur, dan 3) menerapkan keadilan selama tindakan. Penelitian selanjutnya diharapkan dapat mengevaluasi secara kuantitatif kemampuan pengambilan keputusan etik perawat dalam pelaksanaan tindakan invasif selama proses asuhan keperawatan pada bayi prematur.

Abstract (sommario):
Le fonctionnement du cerveau repose sur la libération de molécules telles que les neurotransmetteurs et les métabolites dans le milieu interstitiel. L’étude de ces molécules est donc primordiale afin de mieux comprendre leur rôle physiologique et pathologique. Pour cela, les biocapteurs enzymatiques implantables sont un outil prometteur de par leurs capacités de détection quantitative, en temps réel et dans les tissus profonds. En fonction des dimensions du biocapteur, l’impact de l’implantation peut avoir des conséquences considérables sur la composition chimique du fluide interstitiel. De plus, chaque implantation induit localement une réaction inflammatoire dite « réaction au corps étranger ». La réduction de ces réactions est indispensable afin d’obtenir des estimations plus précises de la concentration des molécules présentes. Dans ce sens, ce manuscrit exposera deux voies de réduction de l’impact lésionnel dû à l’implantation de biocapteurs. Tout d’abord, il sera présenté la miniaturisation de biocapteurs enzymatiques jusqu’à des diamètres externes inférieurs à 15 µm. Et il sera démontré in vivo que ces biocapteurs ultra miniaturisés ont le potentiel d’être implantés dans le cerveau sans induire de dommages détectables aux tissus et aux vaisseaux sanguins. Ensuite, le développement d’une microsonde fabriquée à l’aide des technologies MEMS couplant une détection électrochimique et optique sera introduit dans le cadre du suivi du fluide interstitiel péri- et intratumoral de glioblastomes modifiés pour émettre de la fluorescence. En intégrant deux types de détection sur une unique micro-aiguille, cette microsonde permet de réduire le nombre d’implantations. Ces deux voies de miniaturisation ouvrent la possibilité de suivre la composition chimique du fluide interstitiel de manière moins invasive, et donc de mieux préserver la physiologie des tissus étudiés dans le cerveauBrain function is based on the release of molecules such as neurotransmitters and metabolites into the interstitial fluid. The study of these molecules is essential to better understand their physiological and pathological role. For this purpose, implantable enzymatic biosensors are a promising tool because of their quantitative, real-time and deep tissue detection abilities. Depending on the dimensions of the biosensor, the impact of implantation may have considerable consequences on the chemical composition of the interstitial fluid. In addition, each implantation induces a local inflammatory reaction called "foreign body reaction". The reduction of these reactions is crucial in order to provide more accurate estimations of molecules concentrations present in the interstitial fluid. In this sense, this manuscript will expose two ways of reducing the lesional impact due to the implantation of biosensors. First of all, it will be presented the miniaturization of enzymatic biosensors up to external diameters less than 15 µm. And it will be demonstrated in vivo that these ultra miniaturized biosensors have the potential to be implanted in the brain without inducing detectable damage to tissues and blood vessels. Then, the development of a microprobe fabricated using MEMS technologies combining electrochemical and optical detection will be introduced as part of the monitoring of peri- and intratumoral interstitial fluid from glioblastomes modified to fluoresce. By integrating two types of detection on a single micro-needle, this microprobe reduces the number of implantations. These two miniaturization approaches open up the possibility of following the chemical composition of the interstitial fluid in a less invasive way, and thus of better preserving the physiology of the tissues studied in the brain

Cette espèce, originaire de la côte Est nord-américaine où elle est trouvée dans les marais maritime, a récemment colonisé la Rade de Brest. Les résultats obtenus au cours de ce travail reposent à la fois sur l’écologie, écophysiologie et biogéochimie, ils sont exposés an trois parties. La première partie est dédiée à l’étude de l’écologie de la plante invasive. S. Alterniflora a envahi la Rade de Brest où elle se développe des marais salés jusqu’aux marais tidaux d’eau douce. Le manque de compétiteur lui a même permis de se développer jusqu’en haut du schorre. Il en résulte une homogénéisation de la composition spécifique de la végétation des marais. Afin de mieux comprendre les distributions de S. Alterniflora dans la Rade de Brest, nous avons mesurés les variations des densités, des tailles, et des productions primaires en fonction de l’hydrodynamisme, de la salinité et de la durée de l’immersion. Les productions primaires les plus importantes ont été mesurées chez les plantes soumises à un faible hydrodynamisme, de faibles salinités et des durées d’immersion intermédiaires. La valeur moyenne de la production primaire calculée pour la Rade de Brest est de 1034 g poids sec m-2 an-1. Ce résultat est en accord avec d’autres valeurs estimées pour des spartines dans leurs milieux d'origine et ainsi que dans d’autres sites envahis. La seconde partie porte sur les effets de l’accumulation du silicium chez les plantes sur les mécanismes de résistance aux stress environnementaux. Les phanérogames représentent une composante sous étudiée du cycle du silicium, elles peuvent absorber le silicium sous forme dissoute (dSi) et le stocker sous forme biogénique (bSiO2). Le Si est connu pour sa capacité à réduire l’effet de stress environnementaux de type physique, chimique, et biologique comme les tempêtes, les fortes salinités, la toxicité des métaux lourds, le broutage et certaines maladies. Les objectifs de cette partie étaient de déterminer (1) dans quels organes et quand la bSiO2 est accumulée au cours du cycle de vie de la plante, (2) de savoir si cette accumulation varie en fonction de l’hydrodynamisme, de la salinité, et de la durée de l'immersion, et (3) de savoir si l’accumulation est limitée par la disponibilité en dSi dans les sédiments des marais. Un suivi terrain de 2 ans nous a permis d’échantillonner des plantes dont les contenus en silicium ont été mesurés. Des échantillons de sédiment ont été prélevés à l’échelle saisonnière, et les concentrations en dSi des eaux interstitielles ont été mesurées de O à 10 cm de profondeur. Les résultats permettre de montrer que la bSiO2 s’accumule plus dans les feuilles matures des spartines que dans les autres organes. Nous avons observé une relation linéaire entre les concentrations en bSiO2 et la longueur des plantes. Les concentrations en bSiO2 dans les plantes décroissent avec l’augmentation de l’exposition aux facteurs abiotiques testés. Nous n’avons pas observés de différences entre les disponibilités en dSi de tous les sites étudiés. Les profils de dSi n’ont pas montré de fortes pertes ducs à l’absorption par les racines. Nos résultats suggèrent que la disponibilité en dSi n’est pas un facteur limitant pour l’espèce étudiée. Nous avons montré que chez S. Alteniflora la concentration en bSiO2 n’augmente pas avec l’exposition aux stress, mais à l’inverse qu’elle augmente en corrélation avec la croissance dc la plante. II semble donc que S. Alterniflora a du développer d’autres stratégies pour lutter contre l’effet des stress abiotiques, cependant, cela n’exclut pas le fait que l’accumulation de Si par les plantes peut avoir un effet positif dans la résistance aux stress. Ce travail soulève des questions intéressantes sur les mécanismes d’absorption du Si par les plantes, la disponibilité du Si dans les sédiments et sur son rôle dans la croissance des plantes. La dernière partie de cette thèse est consacrée à l’étude de l’impact de cette plante invasive sur la rétention du silicium dans les marais maritimes. Le silicium (Si) est le second élément le plus important composant la croûte terrestre. Les principaux apports de Si à l’océan proviennent du lessivage des sols cn milieu terrestre et sont véhiculés par les rivières. La silice dissoute (dSi) est bioassimilable par de nombreux organismes aquatiques, marins et terrestres aussi divers que les plantes, les microalgues, les champignons et les bactéries. Les plantes accumulent de la silice biogénique (bSiO2) sous forme de phytolithes qui représentent une part importante des apports fluviaux de Si le long du continuum terre-mer. Le rôle des phanérogames et de leurs phytolithes dans le cycle du Si est encore mal connu. Les activités anthropiques peuvent avoir un impact important sur les apports fluviaux de Si. L’eutrophisation, la construction de barrage et le développement d’espèces invasives peuvent modifier significativement la rétention du Si dans les estuaires. Nous avons étudié les variabilités temporelles et spatiales des profils de dSi et bSiO2 dans les sédiments des marais envahis ou non par la spartine. Nous avons aussi comparé les concentrations annuelles en dSi et bSiO2 des sédiments des marais envahis en fonction de la salinité et de la durée d’immersion. De plus, nous avons réalisé des expériences de dissolution de la bSiO2 dans la litière de spartine et dans les sédiments des marais afin de calculer des constantes de dissolution (kdiss). Dans la seconde partie de cc travail, nous avons utilisé les données obtenues dans la seconde partie de ce travail pour établir des bilans de Si pour des marais envahis et non envahis Nous avons pu observer une tendance saisonnière dans les profils de dSi dont les concentrations augmenteraient du printemps jusqu’à l’automne. Les moyennes annuelles des concentrations en bSiO2 et en dSi dans les sédiments augmentent avec la diminution de la salinité le long du gradient estuarien. A l’inverse, les constantes de dissolution de la bSiO2 augmentent avec la salinité, et la bSiO2 dans la litière de spartine se dissout 5 fois plus vite que celle des sédiments. En comparant les bilans des marais envahis et non envahis, nous avons estimé que la rétention de Si est 2 fois plus importante dans le marais envahis (8 %) que dans le marais non envahis (4 %). L’enfouissement de bSiO2 augmente de 50% dans les marais envahis. Les différences observées peuvent s’expliquer par le fait que S. Alterniflora est une espèce bioingénieure qui augmente la sédimentation. L’effet de l’invasion de S. A1ternlora sur la rétention du Si dans les marais semble plus dû à des processus physiques que biologiques puisque le flux d’absorption de la plante ne représente que 0,1 % de l’apport total de Si dans les rivièresThe aim of this study was to evaluate the impact of the invasive plant Spartina alterniflora on the ecosystem of the Bay of Brest. This species is a tidal marsh plant originating from the East coast of North America, and that have recently colonized the Bay of Brest. This work was performed by coupling studies of ecology, ecophysiology, and biogeochemistry. The first part of this work is dedicated to the ecology of this invasive plant. S. Alterniflora has invaded the Bay of Brest and can now be found from salt marshes to freshwater tidal marshes. The lack of apparent competitors on the high marsh allowed S. Alterniflora to colonize higher tidal elevations and resulted in a homogenization of plant diversity in tidal marshes. To better understand cordgrasses large distribution in the diverse environments of the Bay of Brest (France), we measured stem densities and lengths, and above-ground living and dead biomass at sites differing in their hydrodynamics, soil and water column salinities, and durations of immersion. Low wave energy, low salinity, and intermediate levels of flooding were associated with relatively high levels of growth and primary production determined from calculations of net aerial primary production (NAPP). The mean NAPP value for S. Alterniflora in the Bay of Brest was 1034 g DW m-2 y-1, agreeing with similar estimates from the east coast of the USA and other invaded sites. The second part of this work focused on the effect of the accumulation of silicium and the alleviation of environmental stresses in S. Alterniflora. Vascular plants are an understudied component of the global silicon cycle; they can absorb silicic acid (dSi) and store it as biogenic silica (bSiO2). S. Alterniflora is a Si-accumulating plant in such species Si is believed to alleviate physical, chemical, and biological stresses such as storms, high salinity, heavy metal toxicity, grazing, and disease. Our objectives were to determine (1) in which organ and when bSiO2 accumulates in the plant during its life cycle, (2) whether this accumulation varies with abiotic factors: wave action, estuarine salinity, and duration of immersion, and (3) if the accumulation was limited by dSi availability in marsh porewater. A 2 years field survey allowed to sample plants which were analyzed for there bSiO2 concentrations. Sediment cores were sampled seasonally and the dSi concentrations in the porewater were measured from 0 to 10 cm. BSiO2 accumulated more in mature leaves than in other organs. There was a strong linear relationship between bSiO2 concentration and plant length. BSiO2 concentration did not increase, but rather decreased as a function of exposure to the three abiotic factors tested. DSi availability was not significantly different for each of the tested sites and dSi profiles did not exhibit huge losses in the root zone Our evidence suggests that dSi availability did not seem to be a limiting factor in this case. We showed that bSiO2 did not increase with increasing abiotic stresses but was strongly correlated with growth Hence, S. Alterniflora is likely to have other adaptive strategies for dealing with environmental stressors but it did not exclude the possible role of Si m alleviating these stresses If this is the case, further work is needed to better understand Si uptake, its availability, and its role in silicification and growth in this species. The last part of this work is deals with the impact of the invasive plant on the retention of Si in tidal marshes. Silicon (Si) is the second most import element composition the terrestrial crust. Through weathering, the main inputs of Si to oceans come from lands and are delivered by rivers. Dissolved silica (dSi), is bioavailable for number of aquatic, marine and terrestrial organisms as diverse as terrestrial plants, micro algae, fungi and bacteria. Plants accumulate biogenic silica (bSiO2) as phytoliths, which represents an important component of the riverine Si input along the land-ocean continuum. The role of vascular plants and their phytoliths in the Si cycle remains unclear. Anthropogenic activities have an important impact on riverine nutrient inputs. Eutrophication, dam constructions, and invasive species can significantly modify the retention of Si in estuaries. In this part of the study we investigated temporal and spatial variability and studied the effect of salinity and duration of immersion on the concentration of bSiO2 and dSi measured in sediments of an invaded and non-invaded marsh. In addition, we realized a dissolution experiment of Spartina litter and of marsh sediment in order to estimate the dissolution constant (kdiss). We finally calculated Si budgets m an invaded marsh and in a non-evaded marsh from previously obtained results. This work showed a possible seasonal trend in dSi concentrations increasing from spring to fall. The bSiO2 and the dSi annual mean concentrations m sediment increase with decreasing salinities along the estuarine gradient. We also showed that bSiO2 dissolution rate increase with salinity and that the bSiO2 in S. Alteniflora litter dissolve 5 times faster than in marsh sediments. Comparing the budgets of the invaded and the non-invaded marsh, we observed that the j retention of Si is two times higher in the invaded marsh (8 %) than in the non-invaded marsh (4%). Burial increases by 50 % in the invaded marsh. These differences are explained by the fact that S. Alteniflora is a bioengineer species that increases sediment deposition. The impact of the invasive S. Alterniflora on the retention of bSiO2 seems to be more due to physical than biological processes as uptake of the invasive plant itself represent only 0. 1% of the total Si input

Abstract (sommario):
Le problème principal des patients diabétiques reste les conséquences des complications résultantes du diabète. Un contrôle plus fréquent de la glycémie contribue à l’équilibre du diabète et une diminution importante de ses complications. Les appareils récents de mesure de la glycémie sont moins confortables à cause de la douleur associée à chaque piqûre. Certains appareils sophistiqués de mesure de la glycémie sont semi invasifs, leur duré de validité est de 14 jours. Le but de notre travail de thèse consiste à développer un système de mesure non invasif de la glycémie basé sur une méthode électromagnétique. Un capteur électromagnétique (EM) original est proposé, modélisé sous COMSOL et validé par des mesures expérimentales. Ce capteur se compose de deux cellules de Split Ring Resonator (SRR) excitées par une ligne coplanaire. Notre objectif principal est d’atteindre une sensibilité suffisante pour détecter les différents taux de glucose avec un capteur miniaturisé. Le capteur est testé en premier lieu sur de l’eau glucosée. Il a été optimisé et adapté pour des mesures in-vitro dans le sang. Dans la dernière partie de notre travail, nous avons identifié, quantifié les contraintes impactant les mesures de glycémie. Nous présentons l’étude de deux contraintes sur la mesure du capteur : l’impact de la variation de la dimension de la veine et la dosimétrie. En effet, l’évaluation de ces contraintes permet de compenser leurs effets sur la mesure pour une meilleure précision de la mesure de la glycémieThe main problem of patients with diabetes remains the consequences of the complications resulting from diabetes. More frequent blood glucose control contributes to the balance of diabetes and a significant decrease in its complications. The current devices are less comfortable because of the pain associated with each sting. Some sophisticated blood glucose meters are semi-invasive, and are valid for 14 days. The purpose of my PhD work is to develop a non-invasive blood glucose measurement system based on an electromagnetic method. An original electromagnetic (EM) sensor is proposed, modeled under COMSOL and validated by experimental measurements. This sensor is composed of two Split Ring Resonator (SRR) cells excited by a coplanar line. Our main purpose is to reach sufficient sensitivity to detect different glucose levels with a miniaturized sensor. The sensor is tested on glucose water. Then, it has been optimized and adapted for in-vitro measurements in the blood. In the last part of this study, we identified and quantified the constraints impacting blood glucose measurements. We present the study of two constraints on the measurement of the sensor: Impact of vein dimension and dosimetry. Indeed, the evaluation of these constraints makes it possible to compensate their effects on the measurement for a better precision of the measurement of the glycemia

Abstract (sommario):
Ce travail présente une méthode de positionnement de patients en radiothérapie conformationnelle avec fractionnement de dose. La méthode conçue pour le traitement de lésions intracrâniennes, se base sur un positionnement non-invasif, donc sans cadre stéréotaxique. Des données liées à la tête du patient (nuage de points situés sur la surface cutanée de la tête) et à la lésion (position et forme 3D) sont obtenues de façon standard via une tomodensitométrie. Un capteur surfacique fixé dans la salle de traitement délivre des points situés à la surface du visage du patient, ce dernier représentant l'information remplaçant le cadre. La'lésion peut être ramenée précisément sur l'isocentre de la machine de traitement grâce à la détermination de deux transformations géométriques. La première transformation, obtenue par une étape d'étalonnage, donne la position du capteur 3D dans le système de coordonnées de la machine de traitement. La deuxième transformation (lien géométrique entre le repère de tomodensitomètre et celui du capteur 3D) est obtenue par un recalage de données 3D des deux modalités (tomodensitométrie et lumière visible). La transformation globale ainsi calculée permet d'estimer la position de la lésion dans la salle de traitement en appliquant les deux transformations à la position de la tumeur exprimée dans le repère tomographique. Le patient peut ensuite être déplacé pour amener la lésion à l'isocentre. Un fantôme simulant des lésions intracrâniennes a montré que les tumeurs peuvent être positionnées avec une eueur moyenne inférieure à 2 mm. Cette précision est supérieure à celle de la meilleure méthode non-invasive connueThis work presents a patient positioning method allowing the radiologists to combine conformaI radiotherapy and dose fractioning. This method, developed for the treatment of intracranial lesions, is non invasif and does not need stereotactic frames. Data related to the patient's head (cloud of points spread out over the cutaneous surface of the head) and to the lesion (3D position and shape) are obtained via a CT-scan which is usually performed before a treatment. A surfacing sensor, fixed in the treatment room, delivers points distributed over the surface of the patient's face. These data represent the information replacing the stereotactic frame. The lesion can be precisely positioned onto the treatment machine isocenter thanks to two geometric transformations. The first transformation, computed during a calibration step, gives the position of 3D-sensor in the coordinate system of the treatment machine. The second transformation (geometric reltltionship between the coordinate systems of the CT -scanner and of the 3D- sensor) is obtained by registering the data of the two modalities (CT -scan data and visible light data of the 3D-structured light sensor). The global transformation is used to estimate the lesion position in the treatment room by applying sequentially the two transformations at the tumour position given in the CT coordinate system. The patient can then be displaced to bring the les ion onto the isocenter. Tests with a phantom (plaster head) including halls simulating intracraniallesions have shown that tumours can be positioned with a mean euor smaller than 2 mm. This accuracy is better than the one of the best known non invasif method

Abstract (sommario):
L’implantation cochléaire est aujourd’hui réalisée à travers une mastoïdectomie et une tympanotomie postérieure. L’insertion du porte-électrodes est réalisée manuellement avec un contrôle visuel et un retour sensitif, limités. Ces facteurs sont potentiellement à l’origine de la perte de l’audition résiduelle et participent à la variabilité des performances auditives postopératoires. La première partie du travail a consisté à mettre au point des modèles expérimentaux d’implantation cochléaire. Nous avons pu réaliser des modèles synthétiques de scala tympani à l’échelle 1/1 et des modèles anatomiques humains permettant de visualiser la progression de l’implant lors de son insertion dans la scala tympani. Nous avons aussi mis au point un modèle animal d’implantation cochléaire peu traumatique et de longue durée avec préservation de l’audition de l’oreille implantée. La seconde partie de travail a consisté à concevoir une voie d’abord mini-invasive de la cochlée en partant de la surface mastoïdienne et en fraisant un tunnel à travers le récessus du nerf facial vers la cochlée. Cet accès mini-invasif a pu être réalisé par un fraisage manuel sous guidage par neuronavigation de façon reproductible dans 5 rochers humains. Enfin, nous avons mis au point un outil motorisé d’insertion de porte-électrodes et un banc de mesure d’effort. Nous avons pu mesurer les forces d’insertion du porte-électrodes dans les modèles synthétiques et anatomiques de scala tympani. Ce travail pose les jalons d’une procédure d’implantation cochléaire robotisée avec un accès mini-invasif et une insertion de porte-électrode asservie en effort.

Abstract (sommario):
Abstract Plant-pathogen interactions occur throughout the process of plant invasion: pathogens can acutely influence plant survival and reproduction, while the large densities and spatial distributions of invasive plant species can influence pathogen communities. However, interactions between invasive plants and pathogens are often overlooked during the early stages of invasion. As with introductions of invasive plants, the introduction of agricultural crops to new areas can also generate novel host-pathogen interactions. The close monitoring of agricultural plants and resulting insights can inform hypotheses for invasive plants where research on pathogen interactions is lacking. This chapter reviews the known and hypothesized effects of pathogens on the invasion process and the effects of plant invasion on pathogens and infectious disease dynamics throughout the process of invasion. Initially, pathogens may inhibit the transport of potentially invasive plants. After arrival in a new range, pathogens can facilitate or inhibit establishment success of introduced plants depending on their relative impacts on the introduced plants and resident species. As invasive plants spread, they may encounter novel pathogens and alter the abundance and geographic range of pathogens. Pathogens can mediate interactions between invasive plants and resident species and may influence the long-term impacts of invasive plants on ecosystems. As invasive plants shift the composition of pathogen communities, resident species could be subject to higher disease risk. We highlight gaps in invasion biology research by providing examples from the agricultural literature and propose topics that have received little attention from either field.

Abstract (sommario):
Abstract Invasive plants often occur at high densities and tend to be highly generalist in their interactions with herbivores, pathogens, mycorrhiza, endophytes and pollinators. These characteristics mean that invasive plants should frequently participate in diverse indirect biotic interactions with the surrounding community, mediated by their direct interaction partners (e.g. antagonists and mutualists). Indirect interactions play an important role in many ecological processes, yet we still lack a systematic understanding of the circumstances under which they influence the success and impacts of invasive species. In this chapter, I first describe several of the indirect interaction pathways that are commonly encountered in invasion biology and review their contribution to the impacts of plant invasions on co-occurring species. The literature review revealed that there are now many case studies describing various indirect impacts of invasive plants. However, identical interaction motifs (e.g. plant-enemy-plant, plant-mutualist-plant) can bring about several possible outcomes, depending upon each species' provenance, relative abundances and interaction strengths, abiotic resource availability, spatial and temporal scale and the influence of other species. Moreover, knowledge gaps identified include a lack of studies of indirect facilitation outside of plant-pollinator systems, limited consideration of indirect invader impacts on other non-native species, and the scarcity of generalizable results to date. Second, I integrate the literature with some trending research areas in invasion biology (interaction networks, biogeography, invasion dynamics) and identify some potential future research directions. Finally, I discuss how knowledge about indirect biotic interactions could be incorporated into the management of invasive plants.

Abstract (sommario):
AbstractThe spread of invasive alien species (IAS) is recognized as the most severe threat to biodiversity outside of climate change and anthropogenic habitat destruction. IAS negatively impact ecosystems, local economies, and residents. They are especially problematic because once established, they give rise to positive feedbacks, increasing the likelihood of further invasions and spread. The integration of remote sensing (RS) to the study of invasion, in addition to contributing to our understanding of invasion processes and impacts to biodiversity, has enabled managers to monitor invasions and predict the spread of IAS, thus supporting biodiversity conservation and management action. This chapter focuses on RS capabilities to detect and monitor invasive plant species across terrestrial, riparian, aquatic, and human-modified ecosystems. All of these environments have unique species assemblages and their own optimal methodology for effective detection and mapping, which we discuss in detail.

Abstract (sommario):
AbstractMuch of the literature dealing with the biology and management of invasive species has focused on the damaging ecological and economic consequences of invasions (see Chaps. 10.1007/978-3-030-45367-1_2, 10.1007/978-3-030-45367-1_3, and 10.1007/978-3-030-45367-1_14 of this volume for review). In this chapter, we shift the focus to the causes of invasion, with the goal of proactively limiting or preventing invasions rather than reacting to them once they have occurred. Preventing the introduction of invasive species is one key element in this proactive approach (Chap. 10.1007/978-3-030-45367-1_6, this volume). Here, we specifically focus on ecosystem attributes that affect whether or not an ecosystem is vulnerable to invasion, that is, the features that affect its invasibility (Lonsdale 1999), with particular emphasis on the role of natural and anthropogenic disturbance.

Abstract (sommario):
Abstract There has been growing interest in the consequences of invasive non-native plants for the plant-pollinator mutualism, most likely because of its relevance for the maintenance of terrestrial biodiversity and food production. However, the development of this research field has been thematically uneven and the overall evidence inconclusive. Many studies have focused on how non-native plants interact with native plants via pollinator sharing, which have allowed meta-analytical syntheses, whereas several others have looked at how frequently non-native plants integrate into native plant-pollinator webs and how they affect network structure. However, relatively few studies have addressed the consequences of invasive plants for pollinators. Overall, the research approach in this area has been predominantly phenomenological rather than mechanistic, which has hindered our understanding of apparently contradictory evidence. One key characteristic of invasive non-native plants that seems to mediate negative effects on the pollination mutualism is the high relative abundance that they reach at late stages of invasion. This high dominance is apparently the main trigger of all the disruptive direct and indirect effects that are discussed in this chapter. Finally, we identify several intriguing questions on the ecological and evolutionary consequences of invasive plants for the plant-pollinator mutualism waiting to be answered.

Abstract (sommario):
Objective: The objective of this study was to evaluate survival in patients with 10 or more compromised axillary lymph nodes. Methodology: This is a retrospective cohort study conducted in a private oncology clinic in Teresina, Piauí, Brazil, in the period 1999–2023, where medical records of 12 patients with breast cancer who had 10 or more compromised axillary lymph nodes were analyzed. The following variables were observed: patient age, histological type of tumor, tumor size, lymphatic invasion, vascular invasion, perineural invasion, number of lymph nodes dissected, number of axillary lymph nodes compromised, treatment with radiotherapy and/or chemotherapy, occurrence of recurrence and/or metastasis, and patient survival. Survival functions were calculated using the Kaplan-Meier method. This study was approved by the Research Ethics Committee of the Universidade Estadual do Piauí (CEP-UESPI), Teresina, Piauí, Brazil, opinion number 4.311.835. Results: The mean age of the patients was 58.66 years. The mean tumor size was 4.6 cm. There was a predominance of invasive carcinoma of the non-special histological type (10–83.33%), followed by invasive lobular carcinoma (1–8.33%) and invasive tubular carcinoma (1–8.33%). As for lymphovascular invasion, 6 (50%) patients had vascular invasion, 7 (58.33%) had lymphatic invasion, and 3 (25%) had perineural invasion. The mean number of LAX compromised was 13.17, while the mean number of lymph nodes dissected was 20.25. Of the 12 patients, 9 were treated with radiotherapy (75%) and 10 were treated with chemotherapy (83.33%). Of the total, 6 (50%) patients had some form of recurrence, of whom 4 progressed to death. Distant metastasis occurred in 4 (30%) patients. Conclusion: The survival rate in a time interval of 5 years for patients with 10 or more compromised axillary lymph nodes was 51.6%.

Abstract (sommario):
The spread of invasive species to new areas threatens the stability of ecosystems and causes major economic losses. We propose a novel approach to minimize the spread of an invasive species given a limited intervention budget. We first model invasive species spread using Hawkes processes, and then derive closed-form expressions for characterizing the effect of an intervention action on the invasion process. We use this to obtain an optimal intervention plan based on an integer programming formulation, and compare the optimal plan against several ecologically-motivated heuristic strategies used in practice. We present an empirical study of two variants of the invasive control problem: minimizing the final rate of invasions, and minimizing the number of invasions at the end of a given time horizon. The optimized intervention achieves nearly the same level of control that would be attained by completely eradicating the species, but at only 60-80\% of the cost.

Abstract (sommario):
Review question / Objective: How does the flow state occur in invasion team sports (e.g., prevents; disrupts; restores; triggers; facilitates; hampers) and how does it influence the Elite athletes performance? Rationale: The flow state has been configured as an important flooring condition in the search for the best performance. However, there is an absence of systematizations about the flow state specifically in invasive team sports and its impact on performance. Therefore, it is relevant to qualify the types of studies conducted, their main correlations and causalities, as well as their main evidence and limitations. Condition being studied: The flow in invasion team sports and its impact on the Elite athletes performance.
