Résumé :
Accurate human body profiles have many potential applications. Image-based human body profile estimation can be regarded as a fine-grained semantic segmentation problem, which is typically used to locate objects and boundaries in images. However, existing image segmentation methods, such as human parsing, require significant amounts of annotation and their datasets consider clothes as part of the human body profile. Therefore, the results they generate are not accurate when the human subject is dressed in loose-fitting clothing. In this paper, we created and labeled an under-the-clothes human body contour keypoint dataset; we utilized a convolutional neural network (CNN) to extract the contour keypoints, then combined them with a body profile database to generate under-the-clothes profiles. In order to improve the precision of keypoint detection, we propose a short-skip multi-scale dense (SMSD) block in the CNN to keep the details of the image and increase the information flow among different layers. Extensive experiments were conducted to show the effectiveness of our method. We demonstrate that our method achieved better results—especially when the person was dressed in loose-fitting clothes—than and competitive quantitative performance compared to state-of-the-art methods, while requiring less annotation effort. We also extended our method to the applications of 3D human model reconstruction and body size measurement.

Résumé :
Present paper presents the results concerning the modeling process of extrusion of a profile type “Yalle body”. COSMOS soft was used in order to simulate the extrusion process. 3D model contains elements type SOLID, witch simulates the nonlinear behavior in the field of elasticplastic domain. The constitutive equation of Iliusin and Dracker-Prager relation and Von Misses criterion were used in simulation. The three dimensions model contains 1504 nods and 1750 elements in two different position of the die (optimum position and “out of optimum position”). For both of die positions were presented variation of equivalent total stresses, tangential stresses in different steps (1st step, critical step, and 20th step, by dividing the whole extrusion process in equal steps).

Résumé :
Full car passive and active damping system mathematical model was developed. Computer simulation using MATLAB was performed and analyzed. Two different road profile were used to check the performance of the passive and active damping using Linear Quadratic Regulator controller (LQR)Road profile 1 has three bumps with amplitude of 0.05m, 0.025 m and 0.05 m. Road profile 2 has a bump with amplitude of 0.05 m and a hole of -0.025 m. For all the road profiles, there were 100% amplitude reduction in Wheel displacement, Wheel deflection, Suspension travel and body displacement, and 97.5% amplitude reduction in body acceleration for active damping with LQR controller as compared to the road profile and 54.0% amplitude reduction in body acceleration as compared to the passive damping system. For the two road profiles, the settling time for all the observed parameters was less than two (2) seconds. The present work gave faster settling time for mass displacement, body acceleration and wheel displacement.

Résumé :
Sporadic inclusion body myositis (sIBM) is the most common myopathy in elderly. This disease causes muscle wasting with both distal and proximal affectation. Quadriceps and finger flexors are muscle typically affected. At pathological level, three different features are present in muscle biopsies: inflammation, mitochondrial abnormalities and degeneration. The presence of T-cell infiltrate, ragged-red fibers and rimmed vacuoles are some features linked to these pathological processes. Protein misfolding and aggregation lead to the formation of the mentioned rimmed vacuoles, composed by many different misfolded proteins: β-amyloid, caveolin, phosphor-Tau among others. The accumulation of β-amyloid is also a hallmark of Alzheimer’s disease (AD), which presents some parallelisms with sIBM. In this work, we aimed to evaluate the mitochondrial state in muscle from sIBM patients but also in peripheral blood mononuclear cells (PBMC) to describe the molecular abnormalities that mitochondria could present in this disease. In addition, we aimed to measure plasmatic molecules related to inflammation, mitochondria and degeneration, in search for plasmatic biomarkers in sIBM patients but also in dermatomyositis and polymyositis, both diseases from the inflammatory myopathy group, like sIBM. Regarding mitochondrial analysis, muscle biopsies from 23 sIBM patients were analyzed, as well as 18 controls free of muscle disease. In addition, PBMC from 14 sIBM patients and from 20 controls were assessed as well. MtDNA levels and also mitochondrial respiratory chain complex IV (COX) activity were significantly decreased in muscle from sIBM patients compared to controls. Interestingly, when analyzing PBMC, dysfunction in COX activity was also found. In this tissue, a deregulation in mitochondrial protein synthesis was also found. As 57% of the sIBM patients presented mtDNA deletions, we aimed to evaluate if the presence of mtDNA deletions correlate with impaired mitochondrial parameters. sIBM patients with mtDNA deletions presented the lowest amount of mtDNA, and those patients without deletions showed values more similar to controls. A similar pattern was found when correlating the presence of MFN-2, a protein involved in mitochondrial dynamics. Again, patients with mtDNA deletions presented the lowest amount of this protein, and patients without deletions showed an intermediate values between patients with deletions and controls. Regarding the analysis of plasmatic molecules related to sIBM pathological features, inflammatory, mitochondrial and amyloidogenic molecules were analyzed in plasma samples from 21 sIBM, 20 controls and also in 14 plasma samples from dermatomyositis (DM) and polymyositis (PM) patients, which constitute an inflammatory myopathy different from sIBM group. Inflammatory (IL-6 and TNF-α) and mitochondrial-related (circulating mtDNA, FGF-21 and CoQ) molecules did not show significant differences between groups. However, amyloidogenic molecules (BACE-1, PS-1 and sAPPβ) were increased in sIBM patients respect to controls but also respect to the DM and PM group confirming its implication in sIBM pathogenesis. Sensitivity and specificity test showed that BACE-1 would be the most suitable biomarker for sIBM diagnosis. This thesis describes at molecular level the mitochondrial implication in the disease, and also reinforces the amyloidogenic component in sIBM. In addition, it proposes a plasmatic and non-invasive biomarker that could help in the sIBM diagnosis, especially in discriminating between other inflammatory myopathies, like polymyositis.
La miositis per cossos d’inclusió en la seva forma esporàdica (MCI) és la miopatia més comú en individus de més de 50 anys tot i ser una malaltia rara. Cursa amb atròfia muscular progressiva distal i proximal i actualment no es coneix cura. A nivell histopatològic presenta un component inflamatori, un component mitocondrial i un component degeneratiu. Degut al seu component degeneratiu i a la similitud de les proteïnes que formen aquests cossos d’inclusió, s’ha establert un possible paral·lelisme amb la malaltia d’Alzheimer. Els objectius d’aquesta tesi doctoral són explorar a nivell molecular les alteracions mitocondriales en la MCI en múscul, però també en cèl·lules mononuclears de sang perifèrica (CMSP), ja que és un teixit menys invasiu. A més, com a segon objectiu principal pretén d’estudiar mol·lècules relacionades amb la inflamació, amb el mitocondri i amb la degeneració en plasma d’aquests pacients per tal de demostrar la seva implicación amb la etiopatogènia i a més per establir nous marcadors menys invasius que permetin diagnosticar la malaltia i diferenciarla d’altres malalties similars com la dermatomiositis i la polimiositis. Fent referència a l’estudi mitocondrial, tant la quantitat de DNA mitocondrial com l’activitat del complex IV de la cadena mitocondrial (COX) es van trobar disminuïts en músculs dels pacients amb MCI. D’altra banda, amb l’estudi de les CMSP, també vam trobar disminuïda l’activitat de la COX, i a més una desregulación de la síntesis de proteïnes mitocondrials. Donat que un 57% dels pacients va presentar delecions múltiples al DNA mitocondrial, la presència d’aquestes delecions correlacionava amb una menor quantitat de DNA mitocondrial i a més amb un decrement de proteïna MFN-2, implicada en la dinàmica mitocondrial. Amb l’estudi de les molècul·les plasmàtiques, es van analitzar en plasma de pacients amb MCI, en controls però també en pacients amb dermatomiositis i polimiositis mol·lècules relacionades amb la inflamació (IL-6 i TNF-α), amb el mitocondri (DNA mitocondrial circulant, FGF-21 i enzim CoQ) i amb la amiloidogènesi (BACE-1, PS-1 i sAPPβ). Les mol.lècules amiloidogèniques es trobaven incrementades en els pacients amb MCI respecte controls i altres miopatíes inflamatòries, demostrant la seva impliació en la etiopatogènia i obtenint un cert valor diagnòstic. Amb aquesta tesi, s’ha demostrat la implicació mitocondrial en la etiopatogènia de la MCI, i s’han trobat alteracions en plasma de mol·lècules amiloidogèniques que, a més, tenen potencial diagnòstic per diferenciar aquesta malaltia d’altres miopatíes inflamatòries com la polimiositis.

Résumé :
Patients with cerebral palsy account for great upper extremities deviationswhile walking. However, the number of studies assessing their upper bodygait kinematics are rare and no studies have been conducted interested inthe whole body kinematics during walking. In this study, we created awhole body index, the Body Profile Score made of modified existing kinematicindexes assessing the gait pattern of children with cerebral palsy. TheBody Profile Score (BPS) is an average of combination of the Gait ProfileScore (GPS), a modified Trunk Profile Score (TPS), a modified Arm PostureScore (APS) and a also new index called Head Profile Score (HPS), basedon a similar calculation. Dierent versions of the BPS were tested on threegroups: a control group, a CP group before botulinum toxin A treatmentand a CP group after botulinum toxin A treatment. The results showed apoor level of linear correlations between the dierent BPS versions and theGait Profile Score, indicating that lower body indexes such as the GPS orGait Deviation Index (GDI) and full body index such as the BPS do not renderthe same information. The BPS is the first index proposing a full bodykinematic analysis and aims at showing that such an analysis is needed ingait assessment of spastic children in order to have a realistic overview ofthe pathological walking condition.

Résumé :
Children with end stage liver disease are thought to have reduced lean mass and higher energy requirements. The aim of the study was to assess how body composition and energy requirements of children with end stage liver disease differ from those of healthy children and how they change after liver transplantation as well as to study for metabolic pathways that may be influencing the body composition. Body composition was assessed by various methods including basic anthropometry, stable isotopes, dual-energy X-ray absorptiometry (DXA) and air displacement plethysmography (BOD POD). Resting energy expenditure was assessed by indirect calorimetry. The patients were compared to age and sex matched healthy controls and were re-assessed at least 6 months after they received their liver transplant. Liver, muscle and fat tissue obtained at the time of transplant was assessed by microarray analysis of gene expression and validated with qPCR with a focus on metabolic pathways of glycolysis, lipolysis, insulin resistance and muscle atrophy and in particular the AMPK pathway (a cellular catabolic pathway). Seventeen patients and 14 healthy controls were recruited. Basic anthropometry showed that the patients had significantly lower weight and height. The deuterium, BOD POD and DXA measurements showed that whereas some children had lower lean mass, fat mass (FM) was preserved and remained within the normal range. Body mass index, mid upper arm circumference and FM indices were negatively correlated with stay in hospital post liver transplant. The presence of hypermetabolism was not different between patients and controls. The tissue studies distinguished a subgroup of patients with significant differences in their muscle and fat tissue. These differences were not related to catabolic pathways including AMPK, but were related to a pathway linked to inflammatory mediated insulin resistance involving interleukin-6. In this cohort of patients, in spite of lean mass reduction, fat mass was preserved and correlated with a shorter stay in hospital after liver transplantation. This is relevant information when deciding on appropriate nutritional management prior to transplantation. Some patients may develop insulin resistance as a mechanism of fat mass preservation during their chronic illness. This is the first time a possible mechanism for the insulin resistance described in these patients is identified. Further work would be required to confirm this finding and to link it with clinical evidence of insulin resistance.

Résumé :
The purpose of this study was to measure the change in joint energy of the hip,knee and ankle of the right and left leg, in the sagittal plane during the delivery phase of the rotational shot put. We hypothesized that (1) throwers who produced a greater total hip energy change would have greater horizontal displacement and (2) throwers who produced a higher ratio of hip energy, in each leg independently, would produce greater horizontal displacement. Subjects (n = 8) must have been right-handed, collegiate or post collegiate level throwers trained in the rotational technique. Vicon Nexus System (Denver, CO, USA) used six MX13+, two F20, two T20 cameras recorded at 240 Hz, and the body Plug-in Gait model to track the body position during each trial. Two AMTI force plates (OR-6, Watertown, MA, USA) were used for collecting ground reaction force data at 960 Hz. A linear regression analysis was performed to determine a relationship between total hip energy change and horizontal displacement. A mixed model regression was used to determine any correlation between horizontal distance and left and right energy change ratios. Athletes who produced a greater total hip energy change had the greatest horizontal displacement (p = .022). Also throwers who produced a higher ratio of left hip energy change to total left leg energy produced the greatest horizontal displacement (p = .02). The ratio of right hip energy change to right leg energy change was found to not be significant to horizontal displacement (p = .955). We feel the findings on the left leg energy change are an attempt by the athlete to both accelerate the shot put as well as stop the rotational progression to allow the athlete to complete a fair throw. The athlete extending both the right and the left hip rapidly during the delivery phase can help explain the combined right and left hip energy change. This action accelerates the ball in a proximal-distal sequence, which allows athletes to reach high final shot put velocities. The higher the final velocity on the shot put positively correlates with the horizontal displacement.

Résumé :
With the ability to feel through artificial limbs, users regain more function and increasingly see the prosthetics as parts of their own bodies. So, main focus of this project was dedicated to recuperating sensation by deception both in sighted and unsighted patients, started with illusionary experiments on healthy volunteers, brain signals were captured with medical EEG headsets during these tests to have a better understanding of how the brain works during body ownership illusions. EEG results suggest that gender difference exists in the perception of body transfer illusion. Visual input can be induced to trick the brain. Using the results, a new device has been designed (sound generator system-SGS) with the principal goal to find ways to include rich sensory feedback in prosthetic devices that would aid their incorporation of the user's body representation or schema. Studying the brain is fascinating; SGS tested and was found to have an adequate level of dexterity over course of one-month multiple times. After each try, the results were more tolerable than before that proved the idea that brain can learn and understand anything and can be manipulated temporary or lasting due to influences. Different methods used to validate the results, EEG acquisition, mapping subject brain function with EEG and finally interviewing participant after each attempt. Although the results of the illusion shows that when heat applies on rubber hand, subjects behave in similar manner as if their real hand was effected, but main question is still remains. How can the conditioning apply to daily life of amputees so that illusion become permanent? This is a rapidly developing field with advancements in technology and greater interdisciplinary integration of medicine, mechatronics and control engineering with the future looking to have permanent, low power consumption, highly functional devices with a greater intuitive almost natural feel using a variety of body signals including EMG, ultrasound, and Electrocorticography.

Résumé :
Thesis (MScAgric)--University of Stellenbosch, 2001.
ENGLISH ABSTRACT: The purpose of this study was to determine the essential amino acid requirements of beef cattle under feedlot conditions through evaluation of the duodenal and whole empty body essential amino acid compositions. To define the ideal protein required for growth, the whole empty body essential amino acid compositions of 8 beef steers (Simmental and Hereford crosses) was investigated. The amino acid composition of the components (carcass, metabolic organs and residual fraction), was pooled relative to their respective mass and protein contribution, resulting in the calculated whole empty body amino acid composition: arginine 6.81; histidine 2.69; isoleucine 4.02; leucine 6.96; lysine 7.43; methionine 2.01; phenylalanine 4.03; threonine 4.01; valine 5.30; tryptophan 0.82. Variations in profiles were found between scientific reports, either indicating that ratios change with growth and implants or possibly through genotype. The present study's body amino acid ratios were used to estimate dietary amino acid requirements through evaluation of the duodenal essential amino acid compositions from three different maize based feedlot diets. Although there was a general increase in the biological value of protein after rumen fermentation, the duodenal essential amino acids in comparison with the whole empty body recorded deficient/unbalanced profiles of essential amino acids for growth. The chemical scores suggested that the first-to-thirdlimiting amino acids in the duodenal digesta of beef cattle, that received three different commercially available feedlot diets, were: histidine, lysine, methionine/arginine (Diet 1), histidine, arginine, lysine (Diet 2) and arginine, methionine, histidine (Diet 3). Thedisproportionate duodenal amino acid concentrations obtained from the three diets, emphasise the necessity to enhance the intestinal delivery of amino acid profiles through different undegradable protein sources, with the objective to maximise protein utilisation and obtain the genetic potential for optimal growth in feedlot cattle. When amino acid requirements and flows to the duodenum were simulated using the Cornell Net Carbohydrate and Protein system (CNCPS), predictions indicated that lysine amino acid flow was limiting the metabolizable allowable average daily gain in Diet 1 and 3. Predicted profiles indicated that the order of limitation was: lysine, arginine, histidine (Diet 1), lysine, arginine, histidine, methionine (Diet 2) and lysine, arginine, histidine (Diet 3). The predicted profiles were in accordance with observed duodenal values, except for methionine that was observed limiting in Diet 1 and 3; however, the sequence and extent of limitation varied. Results indicate that prediction models have potential in predicting requirements; however there are still limitations for use to accurately define requirements for particular EAA's. From the present study, it is clear that the protein accretion was constrained by quantity and/or disproportionality of amino acids available for absorption. Further research should therefore be directed towards obtaining a more desirable array of amino acids to the lower digestive tract that is digestible, absorbable and an economically viable option for the feedlot operator.
AFRIKAANSE OPSOMMING: Aminosuurbehoeftes van Voerkraalbeeste Volgens die Duodenale en Totale Lee Liggaam Essensiele Aminosuur Profiel: Die doel van hierdie studie was om die essensiele aminosuur vereistes van vleisbeeste onder voerkraal toestande te bepaal deur die evaluering van die duodenale en totale lee liggaam essensiele aminosuursamesteilings. Om die idea Ie proteiene wat vir groei benodig word te definieer, is 'n ondersoek ingestel na die totale lee liggaam essensiele aminosuursamesteilings van 8 vleisbees osse (Simmetailer en Hereford kruise). Die aminosuursamesteiling van die komponente (karkas, metaboliese organe en residuele fraksie), se massa en proteien bydrae is gebruik om die totale lee liggaam aminosuursamestelling 5005 volg te bereken: arginien 6.81; histidien 2.69; isoleusien 4.02; leusien 6.96; lisien 7.43; metionien 2.01; fenielalanien 4.03; treonien 4.01; valien 5.3; triptofaan 0.82. Variasies in profiele tussen wetenskaplike verslae is gevind. Dit dui daarop dat groei en inplantings of moontlik genotipe 'n invloed op profiele kan he. Die huidige studie se liggaam aminosuurverhoudings is gebruik om die dieet aminosuurbehoeftes te skat deur evaluering van die duodenale essensiele aminosuursamesteilings van drie verskiilende mielie-gebaseerde voerkraal diete. Alhoewel daar 'n algemene toe name in die biologiese waarde van die proteien na rumen fermentasie was, het die duodenale essensiele aminosure in vergelyking met die totale lee liggaam, ongebalanseerde profiele van essensiele aminosure vir groei getoon. Die chemiese teilings toon aan dat die eerste-tot-derde-beperkende aminosure in die duodenale inhoud van vleisbeeste wat drie verskillende kommersieel beskikbare voerkraal diete ontvang het, soos volg is: histidien, lisien, metionieniarginien (Dieet 1), histidien, arginien, lisien (Dieet 2) en arginien, metionien, histidien (Dieet 3). Die ongebalanseerde aminosuur konsentrasies wat in die duodenum van die drie dlete verkry is, beklemtoon die noodsaaklikheid om die intestinale lewering van aminosuurprofiele te verbeter deur verskillende nie-degradeerbare proteien bronne te voer. Die doelwit moet wees om proteien verbruik te optimaliseer en daardeur die genetiese potensiaal vir optimale groei in voerkraalbeeste te bereik. Met die simulering van aminosuurbehoeftes en vloei na die duodenum van die drie standaard voerkraal diete met behulp van die "Cornell Net Carbohydrate and Protein System" (CNCPS), het voorspellings gewys dat lisien aminosuurvloei die metaboliseerbare toelaatbare gemiddelde daaglikse toename in Dieet 1 en 3 beperk het. Voorspelde profiele wys dat die volgorde van beperking soos volg sou wees: lisien, arginien, histidien (Dieet 1), lisien, arginien, histidien, metionien (Dieet 2)' en lisien arginien, histidien (Dieet 3). Die voorspelde profiele was in ooreenstemming met die waargeneemde duodenale waardes, behalwe vir metionien wat beperkend was in Dieet 1 en 3; die volgorde en mate van beperking was egter verskillend. Resultate wys dat voorspellingsmodelle die potensiaal het om behoeftes te voorspel. Vir die akkurate definisie van behoeftes vir spesifieke essensiele aminosuure is daar egter nog beperkinge. Uit die huidige studie, is dit duidelik dat protetenneerleqqinq deur die hoeveelheid en/of oneweredigheid van geabsorbeerde aminosure beperk is. Verdere navorsing moet dus fokus op die verkryging van In meer geskikte profiel van aminosure wat verteerbaar, opneembaar en 'n ekonomiese lewensvatbare opsie vir die voerkraalbestuurder is.

Résumé :
AbstractConventional transcranial magnetic stimulation (TMS) coils are limited by the depth-focality tradeoff rule. To better utilize this depth-focality tradeoff rule, a new approach needs to be employed. In this study, a new multi-layer winding-tilted TMS coil design is proposed for human brain stimulation. It can deliver stimulation with better depth-focality characteristic than the double cone coils to deep brain regions. In our design, circular coils were accumulated along their central axis to improve the field decay rate as a function of the stimulation depth. We also tilted the winding angle of the coils to break the ring-shaped symmetry of the electric field distribution and accomplish the focality. New curves were plotted in the depth-focality tradeoff profile for our coil design, which intersected with the figure-8 coil curve. The new curves break the depth-focality tradeoff, and our coil design presents better focality than the H coils and circular coils, deeper stimulation depth than figure-8 coils, and the capability for multisite brain stimulation due to its unique structure and the limited contact area with the human head surface, which cannot be accomplished with the double cone coils.

Résumé :
AbstractMultichannel Transcranial Magnetic Stimulation (mTMS) provides the capability of stimulating multiple cortical areas simultaneously or in rapid succession by electronic shifting of the E-field hotspots. However, in order to target the desired brain region with intended intensity, the intracranial E-field distribution for all coil elements needs to be determined and subsequently combined to electronically synthesize a ‘hot spot’. Here, we assessed the performance of a computational TMS navigation system that was used to track the position of a 2×3-axis TMS coil array with respect to subject’s head and was integrated with a real-time high-resolution E-field calculation engine to predict the activated cortical regions as the array is moved around the subject’s head. For fast evaluation of the E-fields with high-resolution head models, we employed our previously proposed Magnetic Stimulation Profile (MSP) approach. Our preliminary tests demonstrated the capability of this system to precisely calculate and render E-fields with a frame rate of 6 Hz (6 frames/second). Furthermore, we utilized two z-elements from the 3-axis coils to form a figure of eight coil type and utilized it for suprathreshold stimulation of the hand first dorsal interosseous (FDI) muscle on a healthy human. The recorded motor evoked potentials (MEPs) showed clear activation of the FDI muscle comparable to the activation elicited by a commercial TMS coil. The estimated cortical E-field distributions showed a good agreement between the commercial TMS coil and the two z-elements of the 2×3-axis array.

Résumé :
AbstractGender-affirming treatment for transgender people is characterized by a multidisciplinary approach in which the endocrinologist plays a crucial role. Endocrinologists should explore the desired body changes of each person in order to guarantee a real personalized clinical approach. Most current guidelines include hormonal treatment protocols only for binary transgender people, requesting full virilization or full femininization and de-virilization. However, requests for an individualized treatment in non-binary transgender people are increasing. In this chapter, we review hormonal treatment strategies for binary and non-binary transgender people, describing available compounds, expected body modifications, and safety profile. Although literature in this field has been increasing over the last years, future studies should address long-term outcomes of hormonal treatment and the effects of personalized treatment in non-binary transgender people.

AbstractThis chapter treats the theory of irrotational flows of perfect fluids by the use of complex variables. The theory is based on a complex velocity and the related concepts like circulation, flow rate, complex potential. Several simple examples are given. More elaborated is the flow around a circular cylinder with and without circulation . Using conformal mapping and especially the Joukowski transformation, it is possible to consider an aerodynamics application, namely the flow around an airfoil. Blasius theorem allows for the computation of the forces and moment generated by the flow around an immersed body. It is applied to the case of the cylinder and Joukowski profile.

Résumé :
Abstract The surface profile wear and the resulting third-body layer accumulation are investigated on the Virginia Tech-Federal Railroad Administration Roller Rig (VT-FRA Roller Rig), using a high-precision 3D laser profiler by Keyence. It is observed that the wheel surface gradually wears and the fine worn material accumulates on the running surfaces. It is further observed that with the progression of the wear and accumulation of a powder-like material at running surface, a preocular change in wheel-rail traction occurs. The first step in exploring the physics of the changes in traction is quantifying, precisely, the micron-sized surface finish changes and wear material accumulation. This paper provides the process of choosing a suitable surface profiler for the VT-FRA roller rig adaptation, and the results of a series of tests under various wheel load and contact configurations. A baseline experiment is conducted to evaluate the wheel wear and the accumulation of the naturally-generated third body layer (the worn material) on the wheel’s running surface. Before each series of experiments, the wheel and roller running surfaces were polished and thoroughly cleaned to make sure that they are perfectly smooth (finished) and free of any debris or dust. The wheel surface profile is measured in the perfectly cleaned condition using the 3D laser scanner. Time controlled experiments are run with different wheel loads, % slippage, and angle of attack (AoA) for 500 seconds. For each run, the change with surface finish and accumulated third body layer build up is measured. It is consistently observed that the traction forces increase gradually with time until they reach a stable level, presented by a plateau in the traction-slippage curves. The time to reach the plateau is directly related to wheel’s dynamic conditions including load, %slippage, and AOA. For some of the conditions, such as wheel load, the relationship is linear and for others (such as AOA) it is nonlinear. Concentrating on the analysis of the baseline results, it is observed that the change in surface finish and the third body layer that naturally accumulates at the running surface — hence, referred to as “natural third body layer” or “NTBL” — is directly correlated and somewhat linearly with NTBL and change in the running surface from smooth to rough. The correlation is most noticeable for the NTBL. With increasing NTBL, traction increases rapidly until the running surface is saturated with the accumulated wear material, presumably a ferrous oxide. There is far weaker correlation between the change in surface finish and traction variations. It is noticed that the surface finish continues to change beyond the time that the traction forces reach their plateau, and its effect remains far more gradual than NTBL.

Résumé :
The original objectives were: A. To determine the critical embryonic age for monochromatic green light stimulation. B. To follow the ontogeny of embryos exposed to monochromatic green light vs. darkness. C. To investigate the effects of monochromatic green light illumination on myoblast and fiber development in the embryo. D. To investigate the stimulatory effect of light combinations during embryo and post-hatch periods on growth and meat production. E. To evaluate the direct effect of monochromatic green light on cultured embryonic and adult myoblasts. The overall purpose of this study was to investigate the effect of monochromatic light stimuli during incubation period of broilers on muscle development and satellite cell myogenesis. Based on previous studies (Halevy et al., 1998; Rozenboim et al., 1999) that demonstrated the positive effects of green-light illumination on body and muscle growth, we hypothesized that monochromatic light illumination accelerates embryo and muscle development and subsequently enhances muscle growth and meat production. Thus, further decreases management costs. Under the cooperation of the laboratories at the Hebrew University of Jerusalem and University of Washington we have conducted the following: 1. We have established the critical stage for exposure to green monochromatic light which has the maximal effect on body and muscle growth (Objective A). We report that embryonic day 5 is optimal for starting illumination. The optimal regime of lighting that will eliminate possible heat effects was evaluated by monitoring egg core temperature at various illumination periods. We found that intermitted lighting (15 min. on; 15 min. off) is optimal to avoid heat effects. 2. We have evaluated in detail gross changes in embryo development profile associated to green light stimuli vs. darkness. In addition, we have investigated the stimulatory effect of light combinations during embryo and post-hatch periods on body and muscle growth (Objective B,D). 3. We have studied the expression profile of muscle regulatory proteins during chicken muscle cell differentiation in cultures using newly developed antibodies. This study paved the way for analyzing the expression of these proteins in our photo stimulation experiments (Objective C). 4. We have studied the pattern ofPax7 expression during myogenesis in the posthatch chicken. Experimental chick pectoralis muscles as well adult myoblast cultures were used in this study and the results led us to propose a novel model for satellite cell differentiation and renewal. 5. The effects of monochromatic green light illumination during embryogenesis have been studied. These studies focused on fetal myoblast and satellite cell proliferation and differentiation at pre- and posthatch periods and on the effects on the expression of muscle regulatory proteins which are involved in these processes. In addition, we have analyzed the effect of photo stimulation in the embryo on myofiber development at early posthatch (Objective C). 6. In follow the reviewers' comments we have not conducted Objective E. The information gathered from these studies is of utmost importance both, for understanding the molecular basis of muscle development in the posthatch chicks and for applied approach for future broiler management. Therefore, the information could be beneficial to agriculture in the short term on the one hand and to future studies on chick muscle development in the embryo and posthatch on the other hand.

Résumé :
Objectives of the project: To evaluate the effects of a glucogenic supplement during the peripartum transition period on insulin, hepatic triglyceride accumulation, interval to first ovulation, and progesterone profile in dairy cows. To compare benefits of supplemental fats differing in fatty acid composition and fed prepartum on hepatic triglyceride accumulation, interval to first ovulation, progesterone profile, and uterine prostaglandin production in lactating dairy cows. To assess the differential and carry-over effects of glucogenic and fat supplements fed to peripartum dairy cows on steroidogenesis and fatty acids in ovarian follicles. To determine the carry-over effects of peripartum glucogenic or fat supplements on fertility in high producing dairy cows (modified in year 3 to Israel only). Added during year 3 of project: To assess the activity of genes related to hepatic lipid oxidation and gluconeogenesis following dietary supplementation (USA only). Background: High milk yields in dairy cattle are generally associated with poor reproductive performance. Low fertility results from negative energy balance (NEBAL) of early lactation that delays resumption of ovarian cycles and exerts other carryover effects. During NEBAL, ovulation of ovarian follicles is compromised by low availability of insulin and insulin-like growth factor-I (IGF-I), but fatty acid mobilization from body stores is augmented. Liver function during NEBAL is linked to the resumption of ovulation and fertility: 1) Accumulation of fatty acids by the liver and ketone production are associated with delayed first ovulation; 2) The liver is the main source of IGF-I. NEBAL will continue as a consequence of high milk yield, but dietary supplements are currently available to circumvent the effects on liver function. For this project, supplementation was begun prepartum prior to NEBAL in an effort to reduce detrimental effects on liver and ovarian function. Fats either high or low in unsaturated fatty acids were compared for their ability to reduce liver triglyceride accumulation. Secondarily, feeding specific fats during a period of high lipid turnover caused by NEBAL provides a novel approach for manipulating phospholipid pools in tissues including ovary and uterus. Increased insulin from propylene glycol (glucogenic) was anticipated to reduce lipolysis and increase IGF-I. The same supplements were utilized in both the USA and Israel, to compare effects across different diets and environments. Conclusions: High milk production and very good postpartum health was achieved by dietary supplementation. Peripartum PGLY supplementation had no significant effects on reproductive variables. Prepartum fat supplementation either did not improve metabolic profile and ovarian and uterine responses in early lactation (USA) or decreased intake when added to dry cow diets (Israel). Steroid production in ovarian follicles was greater in lactating dairy cows receiving supplemental fat (unsaturated), although in a field trail fertility to insemination was not improved.

Résumé :
Chemical composition and biological role of the surface coat (SC) of the root-knot nematodes, Meloidogyne spp. are described. SC proteins of M. incognita race 3 infective juveniles (J2) were characterized by electrophoresis and western blotting of extracts from radioiodine and biotin-labelled nematodes. J2 labelled with radioiodine and biotin released 125I and biotin-labelled molecules into water after 20 hours incubation, indicating that SC proteins may be loosely attached to the nematode. Antiserum to the principal protein reacted with the surface of live J2 and with surface proteins previously separated by electrophoresis. Human red blood cells (HRBC) adhered to J2 of several tylenchid nematodes over the entire nematode body. HRBC adhered also to nylon fibers coated with SC extracted from M. javanica J2; binding was Ca++/Mg++ dependent, and decreased when the nylon fibers were coated with bovine serum albumin, or pre-incubated with fucose and mannose. These experiments support a working hypothesis that RBC adhesion involves carbohydrate moieties of HRBC and carbohydrate-recognition domain(s) (CRD) distributed on the nematode surface. To our knowledge, this is the first report of a surface CRD i the phylum Nematoda. Gold-conjugated lectins and neoglycoproteins combined with silver enhancement have been used for the detection of carbohydrates and CRD, respectively, on the SC of M. javanica J2. Biotin reagents were used to trace surface proteins, specifically, on live J2. The labile and transitory nature of the SC was demonstrated by the dynamics of HRBC adherence to detergent-treated J2, J2 at different ages or fresh-hatched J2 held at various temperatures. SC recovery was demonstrated also by a SDS-PAGE profile. Monoclonal antibodies developed to a cuticular protein of M. incognita J2 gave a slight, but significant reduction in attachment of Pasteuria penetrans spores. Spore attachment as affected by several enzymes was inconsistent: alcian blue, which specifically blocks sulfyl groups, had no afffect on spore attachment. Treatment with cationized ferritin alone or catonized ferritin following monoclonal antibody caused significant decreases in spore attachment. Those results suggest a role in attachment by negatively charged groups.

Résumé :
Plant yield largely depends on a complex interplay and feedback mechanisms of distinct hormonal pathways. Over the past decade great progress has been made in elucidating the global molecular mechanisms by which each hormone is produced and perceived. However, our knowledge of how interactions between hormonal pathways are spatially and temporally regulated remains rudimentary. For example, we have demonstrated that although the BR receptor BRI1 is widely expressed, the perception of BRs in epidermal cells is sufficient to control whole-organ growth. Supported by additional recent works, it is apparent that hormones are acting in selected cells of the plant body to regulate organ growth, and furthermore, that local cell-cell communication is an important mechanism. In this proposal our goals were to identify the global profile of translated genes in response to BR stimulation and depletion in specific tissues in Arabidopsis; determine the spatio-temporal dependency of BR response on auxin transport and signaling and construct an interactive public website that will provide an integrated analysis of the data set. Our technology incorporated cell-specific polysome isolation and sequencing using the Solexa technology. In the first aim, we generated and confirmed the specificity of novel transgenic lines expressing tagged ribosomal protein in various cell types in the Arabidopsis primary root. We next crossed these lines to lines with targeted expression of BRI1 in the bri1 background. All lines were treated with BRs for two time points. The RNA-seq of their corresponding immunopurified polysomal RNA is nearly completed and the bioinformatic analysis of the data set will be completed this year. Followed, we will construct an interactive public website (our third aim). In the second aim we started revealing how spatio-temporalBR activity impinges on auxin transport in the Arabidopsis primary root. We discovered the unexpected role of BRs in controlling the expression of specific auxin efflux carriers, post-transcriptionally (Hacham et al, 2012). We also showed that this regulation depends on the specific expression of BRI1 in the epidermis. This complex and long term effect of BRs on auxin transport led us to focus on high resolution analysis of the BR signaling per se. Taking together, our ongoing collaboration and synergistic expertise (hormone action and plant development (IL) and whole-genome scale data analysis (US)) enabled the establishment of a powerful system that will tell us how distinct cell types respond to local and systemic BR signal. BR research is of special agriculture importance since BR application and BR genetic modification have been shown to significantly increase crop yield and to play an important role in plant thermotolerance. Hence, our integrated dataset is valuable for improving crop traits without unwanted impairment of unrelated pathways, for example, establishing semi-dwarf stature to allow increased yield in high planting density, inducing erect leaves for better light capture and consequent biomass increase and plant resistance to abiotic stresses.

Résumé :
The general objective of this BARD project focused on rationally designed insect neuropeptide (NP) agonists and antagonists, their application for the characterization of the mechanisms of action of the pyrokinin/PBAN (PK-PBAN) family and the development of biostable, bioavailable versions that can provide the basis for development of novel, environmentally-friendly pest insect control agents. The specific objectives of the study, as originally proposed, were to: (i) Test stimulatory potencies of rationally designed backbone cyclic (BBC) peptides on pheromonotropic, melanotropic, myotropic and pupariation activities; (ii) Test the inhibitory potencies of the BBC compounds on the above activities evoked either by synthetic peptides (PBAN, LPK, myotropin and pheromonotropin) or by the natural endogenous mechanism; (iii) Determine the bioavailability of the most potent BBC compounds that will be found in (ii); (iv) Design, synthesize and examine novel PK/PBAN analogs with enhanced bioavailability and receptor binding; (v) Design and synthesize ‘magic bullet’ analogs and examine their ability to selectively kill cells expressing the PK/PBAN receptor. To achieve these goals the agonistic and antagonistic activities/properties of rationally designed linear and BBC neuropeptide (NP) were thoroughly studied and the information obtained was further used for the design and synthesis of improved compounds toward the design of an insecticide prototype. The study revealed important information on the structure activity relationship (SAR) of agonistic/antagonistic peptides, including definitive identification of the orientation of the Pro residue as trans for agonist activity in 4 PK/PBANbioassays (pheromonotropic, pupariation, melanotropic, & hindgut contractile) and a PK-related CAP₂b bioassay (diuretic); indications that led to the identification of a novel scaffold to develop biostbiostable, bioavailable peptidomimetic PK/PBANagonists/antagonists. The work led to the development of an arsenal of PK/PBAN antagonists with a variety of selectivity profiles; whether between different PKbioassays, or within the same bioassay between different natural elicitors. Examples include selective and non-selective BBC and novel amphiphilic PK pheromonotropic and melanotropic antagonists some of which are capable of penetrating the moth cuticle in efficacious quantities. One of the latter analog group demonstrated unprecedented versatility in its ability to antagonize a broad spectrum of pheromonotropic elicitors. A novel, transPro mimetic motif was proposed & used to develop a strong, selective PK agonist of the melanotropic bioassay in moths. The first antagonist (pure) of PK-related CAP₂b diuresis in flies was developed using a cisPro mimetic motif; an indication that while a transPro orientation is associated with receptor agonism, a cisPro orientation is linked with an antagonist interaction. A novel, biostablePK analog, incorporating β-amino acids at key peptidase-susceptible sites, exhibited in vivo pheromonotropic activity that by far exceeded that of PBAN when applied topically. Direct analysis of neural tissue by state-of-the-art MALDI-TOF/TOF mass spectrometry was used to identify specific PK/PK-related peptides native to eight arthropod pest species [house (M. domestica), stable (S. calcitrans), horn (H. irritans) & flesh (N. bullata) flies; Southern cattle fever tick (B. microplus), European tick (I. ricinus), yellow fever mosquito (A. aegypti), & Southern Green Stink Bug (N. viridula)]; including the unprecedented identification of mass-identical Leu/Ile residues and the first identification of NPs from a tick or the CNS of Hemiptera. Evidence was obtained for the selection of Neb-PK-2 as the primary pupariation factor of the flesh fly (N. bullata) among native PK/PK-related candidates. The peptidomic techniques were also used to map the location of PK/PK-related NP in the nervous system of the model fly D. melanogaster. Knowledge of specific PK sequences can aid in the future design of species specific (or non-specific) NP agonists/antagonists. In addition, the study led to the first cloning of a PK/PBAN receptor from insect larvae (S. littoralis), providing the basis for SAR analysis for the future design of 2ⁿᵈgeneration selective and/or nonselective agonists/antagonists. Development of a microplate ligand binding assay using the PK/PBAN pheromone gland receptor was also carried out. The assay will enable screening, including high throughput, of various libraries (chemical, molecular & natural product) for the discovery of receptor specific agonists/antagonists. In summary, the body of work achieves several key milestones and brings us significantly closer to the development of novel, environmentally friendly pest insect management agents based on insect PK/PBANNPs capable of disrupting critical NP-regulated functions.

Depressed mothers and their offspring differ in terms of health risk profiles and allostatic load. ACAMH, octobre 2020. http://dx.doi.org/10.13056/acamh.13527.

Texte intégral
Résumé :
Allostatic load is essentially the “wear and tear” that accumulates in the body in individuals exposed to chronic stress. Because some patients with psychiatric disorders have a shorter lifespan than their healthy counterparts,1 some researchers have suggested that there might be a link between disorders such as depression and increased allostatic load.
