Abstract
INTRODUCTION The elderly population, which is more active than before, is increasingly suffering from trauma (loss of reflexes and systemic pathologic conditions). Surgical management may be more controversial due to the potential consequences of general anesthesia and the sometimes negligible consequences of functional management. The main objective of this study was to analyze the causes and location of facial fractures in subjects older than 65 years. The secondary objective was to evaluate the management of these fractures (surgical or functional) according to comorbidities. MATERIAL & METHODS In this retrospective study (over a five-year period), we analyzed the causes and management of facial fractures in patients aged over 65 years, and the medical history of each patient was investigated. RESULTS One hundred and nineteen patients with 198 facial fractures were included. The main cause of fractures was a fall (50%). The zygomatic region (39.9%) and mandible (27.8%) were the sites of the most frequent fractures. Comorbidities were found in 84.9% of patients, the majority of which were cardiovascular diseases (82.3%). 75.8% of fractures were treated surgically and 4.8% of patients had complications. DISCUSSION This work is a help to understanding the causes and consequences of facial trauma in the elderly population. The management of these facial fractures requires a multidisciplinary assessment, taking into account the patient's medical history and evaluating the risks and benefits of a surgical procedure with general anesthesia.

Abstract
INTRODUCTION Orbital floor fracture (OFF) are frequently associated with zygomatic fractures (ZF). The reduction of the ZF may modify the features of the associated OFF. Intraoperative cone beam CT (CBCT) has shown diagnostic performance of OFF. The aim of our study was to evaluate how intraoperative CBCT control made after the reduction of ZF may help to take a decision on the associated OFF. MATERIAL AND METHOD Patients with a unilateral displaced ZF associated with an OFF were consecutively included during a 3-year period. Intraoperative CBCT, systematically performed after reduction of the ZF, allowed to decide if the OFF needed reconstruction. The preoperative estimation made on MDCT and the intraoperative decision regarding the OFF were compared. RESULTS Fifty-nine consecutive patients could be included in the study. Nineteen OFF were presumed to be surgical indications on the preoperative MDCT but only 16 indications were confirmed on the intraoperative CBCT, meaning that 3 OFF behaved favorably during the ZF reduction. Forty orbital floor fractures were presumed to be non-surgical on the preoperative MDCT but 6 of them worsened during ZF reduction and became surgical indications. Overall, the intraoperative CBCT control had an impact on 9 (15.3%) of the OFF. CONCLUSION Our study showed that OFF after ZF reduction may evolve favorably or, on the contrary, get worse in 15% of the cases. Surgical indication on an OFF can therefore be confirmed intraoperatively. This allows to avoid under-treatment in the patients where the OFF worsens after ZF reduction and over-treatment in the patient where the OFF reduces after ZF.

Abstract
We present the first joint analysis of cluster abundances and auto or cross-correlations of three cosmic tracer fields: galaxy density, weak gravitational lensing shear, and cluster density split by optical richness. From a joint analysis (4×2pt+N) of cluster abundances, three cluster cross-correlations, and the auto correlations of the galaxy density measured from the first year data of the Dark Energy Survey, we obtain Ω_{m}=0.305_{-0.038}^{+0.055} and σ_{8}=0.783_{-0.054}^{+0.064}. This result is consistent with constraints from the DES-Y1 galaxy clustering and weak lensing two-point correlation functions for the flat νΛCDM model. Consequently, we combine cluster abundances and all two-point correlations from across all three cosmic tracer fields (6×2pt+N) and find improved constraints on cosmological parameters as well as on the cluster observable-mass scaling relation. This analysis is an important advance in both optical cluster cosmology and multiprobe analyses of upcoming wide imaging surveys.

Abstract
In recent years, many γ-ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-correlation with gravitational tracers of matter in the Universe has been shown to be a promising tool. We report here the first identification of a cross-correlation signal between γ rays and the distribution of mass in the Universe probed by weak gravitational lensing. We use data from the Dark Energy Survey Y1 weak lensing data and the Fermi Large Area Telescope 9-yr γ-ray data, obtaining a signal-to-noise ratio of 5.3. The signal is mostly localized at small angular scales and high γ-ray energies, with a hint of correlation at extended separation. Blazar emission is likely the origin of the small-scale effect. We investigate implications of the large-scale component in terms of astrophysical sources and particle dark matter emission.

Abstract
The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, weak gravitational lensing, and galaxy clustering. Here we present combined results from these probes, deriving constraints on the equation of state, w, of dark energy and its energy density in the Universe. Independently of other experiments, such as those that measure the cosmic microwave background, the probes from this single photometric survey rule out a Universe with no dark energy, finding w=-0.80_{-0.11}^{+0.09}. The geometry is shown to be consistent with a spatially flat Universe, and we obtain a constraint on the baryon density of Ω_{b}=0.069_{-0.012}^{+0.009} that is independent of early Universe measurements. These results demonstrate the potential power of large multiprobe photometric surveys and pave the way for order of magnitude advances in our constraints on properties of dark energy and cosmology over the next decade.

Abstract
We introduce and study in two dimensions a new class of dry, aligning active matter that exhibits a direct transition to orientational order, without the phase-separation phenomenology usually observed in this context. Characterized by self-propelled particles with velocity reversals and a ferromagnetic alignment of polarities, systems in this class display quasi-long-range polar order with continuously varying scaling exponents, yet a numerical study of the transition leads to conclude that it does not belong to the Berezinskii-Kosterlitz-Thouless universality class but is best described as a standard critical point with an algebraic divergence of correlations. We rationalize these findings by showing that the interplay between order and density changes the role of defects.

Abstract
Muscle tissue engineering can provide support to large congenital skeletal muscle defects using scaffolds able to allow cell migration, proliferation and differentiation. Acellular extracellular matrix (ECM) scaffold can generate a positive inflammatory response through the activation of anti-inflammatory T-cell populations and M2 polarized macrophages that together lead to a local pro-regenerative environment. This immunoregulatory effect is maintained when acellular matrices are transplanted in a xenogeneic setting, but it remains unclear whether it can be therapeutic in a model of muscle diseases. We demonstrated here for the first time that orthotopic transplantation of a decellularized diaphragmatic muscle from wild animals promoted tissue functional recovery in an established atrophic mouse model. In particular, ECM supported a local immunoresponse activating a pro-regenerative environment and stimulating host muscle progenitor cell activation and migration. These results indicate that acellular scaffolds may represent a suitable regenerative medicine option for improving performance of diseased muscles.

Abstract
AIM This study described and compared the perception of hypoglycaemia in both patients with type 1 diabetes and diabetologists. METHODS This was an observational cross-sectional study undertaken in France in 2011. Data for what hypoglycaemia represents and practices related to it were collected using a questionnaire completed by patients with type 1 diabetes (all>12 years of age) and their diabetologists. Agreement between patients and physicians was evaluated by the intraclass correlation coefficient (ICC) and Gwet's coefficient (GC). RESULTS A total of 485 patients were enrolled by 118 diabetologists. Half the patients thought that hypoglycaemia was always symptomatic. According to both patients and diabetologists, hypoglycaemia impaired quality of life, caused anxiety and was disturbing, especially at night. Clinical symptoms of hypoglycaemia (sweating, shakiness, anxiety) were linked to patient's age and diabetes duration. Regarding hypoglycaemia frequency, agreement was good for severe hypoglycaemia (GC: 0.61 and 0.72 for diurnal and nocturnal hypoglycaemia, respectively) and poor for mild hypoglycaemia (ICC: 0.44 and 0.40, respectively). Diabetologists correctly evaluated the impact of hypoglycaemia on quality of life, but overestimated the hypoglycaemia-induced burden and anxiety. Counteractive behaviours were frequent: 23% of patients decreased their insulin dose, 20% increased their sugar intake and 12% ate extra snacks. Diabetologists were generally aware of these measures, but not of how often patients used them. CONCLUSION Diabetologists and patients do not share enough information about hypoglycaemia. Fear of hypoglycaemia and counteractive behaviours should be looked for by diabetologists. Systematic advice and specially adapted education should also be provided to increase patients' awareness of hypoglycaemia.

Abstract
CONTEXT Maternally inherited diabetes and deafness (MIDD) is a rare form of diabetes with a matrilineal transmission, sensorineural hearing loss, and macular pattern dystrophy due to an A to G transition at position 3243 of mitochondrial DNA (mtDNA) (m.3243A>G). The phenotypic heterogeneity of MIDD may be the consequence of different levels of mutated mtDNA among mitochondria in a given tissue. OBJECTIVE The aim of the present study was thus to ascertain the correlation between the severity of the phenotype in patients with MIDD and the level of heteroplasmy in the blood leukocytes. PARTICIPANTS The GEDIAM prospective multicenter register was initiated in 1995. Eighty-nine Europid patients from this register, with MIDD and the mtDNA 3243A>G mutation, were included. Patients with MELAS (mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes) or with mitochondrial diabetes related to other mutations or to deletions of mtDNA were excluded. RESULTS A significant negative correlation was found between levels of heteroplasmy and age of the patients at the time of sampling for molecular analysis, age at the diagnosis of diabetes, and body mass index. After adjustment for age at sampling for molecular study and gender, the correlation between heteroplasmy levels and age at the diagnosis of diabetes was no more significant. The two other correlations remained significant. A significant positive correlation between levels of heteroplasmy and HbA(1c) was also found and remained significant after adjustment for age at molecular sampling and gender. CONCLUSIONS These results support the hypothesis that heteroplasmy levels are at least one of the determinants of the severity of the phenotype in MIDD.

Abstract
AIMS/HYPOTHESIS We assessed the prevalence and determinants of retinal and renal complications in patients with maternally inherited diabetes and deafness (MIDD). METHODS This was a multicentre prospective study comparing the prevalence of retinopathy and renal disease in 74 patients with MIDD and 134 control patients matched for sex, age and clinical presentation at onset of diabetes, duration of diabetes and current treatment. Comparisons were adjusted for HbA(1c) and hypertension. RESULTS In MIDD patients, HbA(1c) (7.6 +/- 1.6 vs 8.5 +/- 2.0%, p < 0.002), systolic blood pressure (126.6 +/- 16.2 vs 133.1 +/- 17.3 mmHg, p < 0.007) and prevalence of hypertension (33.8 vs 64.2%, p < 0.0001) were lower than in control patients. Prevalence of diabetic retinopathy was 3.7-fold lower in MIDD patients (6/74, 8 vs 40/134, 29.6%, p < 0.0001). Differences between groups remained significant after adjustment for hypertension, systolic blood pressure and HbA(1c). In MIDD, urinary albumin excretion (314.8 vs 80.1 mg/24 h, p = 0.035) and creatinine plasma levels (103.5 vs 82.2 micromol/l, p = 0.0178) were higher and GFR was lower. Impaired renal function (GFR <60 ml/min) was four- to sixfold more frequent in MIDD. Differences between MIDD and control diabetic patients further increased when adjusted for HbA(1c) and systolic blood pressure (p < 0.0001). Adjustment for treatment with an ACE inhibitor or angiotensin II receptor antagonist did not modify the results. CONCLUSIONS/INTERPRETATION This study indicates that diabetic retinopathy is less prevalent in MIDD than in control diabetes. This suggests that retinal alterations due to mitochondrial disease may have a protective role. By contrast, nephropathy is far more frequent in MIDD, suggesting the presence of a specific renal disease independent of diabetic nephropathy.

Abstract
Management of obesity is often reduced to counselling, focusing on factors directly affecting energy balance: food intake and physical activity. However, the causes of excessive food intake, eating disorders and their causal factors, are largely unknown. This can lead to unsuitable obesity management. In the present text, we detail the clinical elements which can be helpful for the specialist or general practitioner making a global assessment of their overweight patients. The goal is to help the patient establish a care project with medical support, as would be the case for any chronic disease.

Abstract
OBJECTIVE In patients with maternally inherited diabetes and deafness (MIDD), due to 3 243 A > G mutation of mitochondrial DNA (mtDNA), diabetes may present with variable phenotypes. OBJECTIVE To ascertain the existence of two distinct phenotypes, MIDD1 and MIDD2, in a series of patients with MIDD. DESIGN Multicenter prospective study. PATIENTS 77 patients with diabetes and the mtDNA 3243 mutation and 139 control patients with type 1 (T1D) or type 2 (T2D) diabetes, matched according to initial presentation of diabetes, age at onset, sex, and duration of diabetes (24 T1D and 115 T2D, including 55 treated with insulin). MEASUREMENTS Anthropometric characteristics (height, body weight, body mass index [BMI], sex), family history of diabetes, and characteristics of diabetes (age at onset, treatment, hemoglobin A1c [HbA1c]), extrapancreatic manifestations. RESULTS In 13 cases (17%, MIDD1), diabetes presented as insulin-dependent from the onset, with ketoacidosis in 6 cases. In 64 cases (83%, MIDD2), diabetes resembled T2D, and was treated with diet in 12 cases, oral hypoglycemic agents in 21 cases, or insulin in 31 cases. Compared with patients with MIDD2, patients with MIDD1 were characterized by lower age at onset of first manifestation of MIDD (25.4 +/- 9.6 vs 33.7 +/- 13.2 Years, P<0.0005), lower body weight (49.1 +/- 7.4 vs 56.3 +/- 10.9 kg, P<0.0025), lower BMI (18.2 +/- 2.3 vs 20.9 +/- 3.6 kg/m2, P<0.0005), and higher HbA1c levels (9.5 +/- 2.0 vs 7.5 +/- 1.6%, P<0.0005). Frequency of family history of diabetes and of extrapancreatic manifestations was the same in both MIDD subtypes. No difference was found within the MIDD2 subtype when comparing patients treated with or without insulin. Compared with matched controls, patients with MIDD had a lower BMI (MIDD1/T1D 18.2 +/- 2.3 vs 24.0 +/- 3.6 kg/m2 and MIDD2/T2D 20.9 +/- 3.6 vs 30.2 +/- 5.9 kg/m2, P<0.0025). Lastly, male patients with MIDD had a shorter height than controls (MIDD1/T1D: 166.1 +/- 3.2 vs 177.3 +/- 6.6 cm and MIDD2/T2D: 168.4 +/- 7.2 vs 173.6 +/- 6.6 cm P<0.025). CONCLUSIONS These results confirm the existence of two different phenotypes in MIDD, MIDD1 and MIDD2, which may be related to the severity of the mitochondrial disease. The role of other genetic and/or environmental factors in the variable phenotype of MIDD remains to be elucidated.

Abstract
Adults derive 3-D information from 2-D images by initially processing local line junction cues and then combining information from many junctions. Prior research indicates that 3-month-olds are sensitive to 3-D cues in individual line junctions. In Experiment 1, we examined whether infants are sensitive to holistic combinations of line junctions that adults use to derive overall 3-D structure. Infants detected a misoriented shape in an array depicting 3-D blocks but not in 2-D patterns that contained all of the trilinear junctions of the 3-D shapes but without the connecting lines. Thus, like adults, infants exhibited sensitivity to holistic combinations of line junctions rather than to individual junctions. In Experiment 2, when confronted with two test patterns, one containing an individual novel element among 15 familiar elements and the other containing a single familiar element among 15 novel elements, infants preferred to look at the former pattern in the 3-D condition but at the latter pattern in the 2-D condition. Thus, akin to pop-out in adults, discrepancies in 3-D cues selectively engaged infants' attention. These results suggest that 3-month-olds are not only sensitive to holistic combinations of line junctions that adults use to derive 3-D information but also selectively attend to these 3-D cues in static images.

Abstract
OBJECTIVE To clarify the impact of type 2 diabetes mellitus on the gastric emptying rate. MATERIAL AND METHODS Using a double-isotope scintigraphic technique, we assessed the gastric emptying of a standard liquid-solid meal in 13 obese type 2 diabetic patients without autonomic neuropathy (age: 47.4 +/- 8.6 yr, body mass index: 33.9 +/- 4.8 kg/m(2), glycaemia: 9.1 +/- 2.6 mmol/l) and in 7 controls with similar sex ratio, age, BMI and body fat distribution. RESULTS The half gastric emptying time for the liquid phase was not significantly different between diabetic patients and controls (respectively: 52.7 +/- 14.5 min and 63.1 +/- 15.2 min). However, the half gastric emptying time for the solid phase was significantly shortened in diabetic patients versus controls (respectively 88.8 +/- 23.2 min in diabetic patients and 113.6 +/- 26.9 min in controls; p<0.04). Furthermore, a negative relationship was highlighted between the half gastric emptying time for the solid phase and basal glycaemia (r=-0.65, p<0.02) in diabetic patients. No significant relationship was found between gastric emptying parameters and cardiac autonomic nerve function, insulin or gastrin levels. CONCLUSION Solid gastric emptying is accelerated in obese type 2 diabetic patients without patent autonomic neuropathy when compared to obese non diabetic patients.

Abstract
BACKGROUND Maternally inherited diabetes and deafness (MIDD), which is seen in 0.5% to 2.8% of patients with type 2 diabetes mellitus, is related to a point mutation at position 3243 of mitochondrial (mt) DNA. Its clinical description is incomplete. OBJECTIVE To study the clinical presentation and complications of diabetes in patients with MIDD and to identify clinical characteristics that may help select diabetic patients for mtDNA mutation screening. DESIGN Multicenter prospective descriptive study. SETTING 16 French departments of internal medicine, diabetes and metabolic diseases, or both. PATIENTS 54 patients with type 2 diabetes mellitus and the mtDNA 3243 mutation. MEASUREMENTS Characteristics of diabetes, metabolic control (glycosylated hemoglobin level), complications of diabetes, and involvement of other organs. RESULTS On average, patients with MIDD were young at diabetes onset and presented with a normal or low body mass index. None were obese. Seventy-three percent of probands had a maternal family history of diabetes. Diabetes was non-insulin-dependent at onset in 87% of patients; however, 46% of patients had non-insulin-dependent disease at onset but progressed to insulin therapy after a mean duration of approximately 10 years. Neurosensory hearing loss was present in almost all patients. Eighty-six percent of patients who received an ophthalmologic examination had macular pattern dystrophy (a specific retinal lesion). Forty-three percent of patients had myopathy, 15% had cardiomyopathy, and 18% (9 of 51) had neuropsychiatric symptoms. Although the prevalence of diabetic retinopathy was 8% among patients who received an ophthalmologic examination, lower than expected after a mean 12-year duration of diabetes, prevalence of kidney disease was 28%. This suggests that a specific renal involvement was the result of mitochondrial disease. CONCLUSIONS Maternally inherited diabetes and deafness has a specific clinical profile that may help identify diabetic patients for mtDNA testing.

Abstract
In vitro and animal studies have shown that glucagon and glucagon-like peptide-1 (GLP-1)-(7-36) amide may participate in the regulation of lipolysis. However, results on human subjects in vivo are inconclusive. To avoid confounding effects, such as changes in insulin secretion when perfusing hormones iv, we used the in situ microdialysis to analyze the impact of human glucagon and GLP-1 on lipolysis rates and local blood flow. Nine healthy volunteers were given an 80-min local perfusion of each hormone (10(-6) mol/L), both in skeletal muscle (gastrocnemius) and in sc abdominal adipose tissue, after a basal period with perfusion of Ringer's solution. Variations in the lipolysis rate and blood flow, respectively, were assessed by measuring of the dialysate glycerol content and the ethanol ratio (outgoing-to-ingoing ethanol concentration). The in vitro relative recovery of the microdialysis probes was 5.2 +/- 1.2%. No significant effects of either GLP-1 or glucagon on either lipolysis rate or blood flow were detected in muscle or adipose tissue. Isoprenaline (10(-6) mol/L), which was perfused after glucagon or GLP-1 in the same catheters, significantly increased the lipolysis rate (a 249% increase of dialysate glycerol in adipose tissue and a 72% increase in skeletal muscle). Furthermore, isoprenaline, but not glucagon or GLP-1, stimulated lipolysis in vitro in isolated human sc adipose tissue. We conclude that neither glucagon nor GLP-1 affect the lipolysis rate of human sc adipose tissue or skeletal muscle.

Abstract
Many models of object perception posit that adults encode individual features in visual scenes before processing the conjunction relations among these features to generate holistic representations. Prior research suggests that infants detect textural discrepancies based on individual features more readily than those based on feature conjunctions. While these results suggest adult-like qualitative differences in infants' processing of features versus conjunctions, there are potential alternative explanations. We examined three such explanations: (1) failure to process one of the features that constitute the conjunction, (2) failure to encode and remember conjunction information that is necessary to detect conjunction-based textural discrepancies, and (3) the fact that conjunction-based discrepancies involve stimuli that are more similar to original stimuli than those involving feature-based discrepancies. None of these factors could explain 5.5-month-olds' superior processing of featural than conjunction-based textural discrepancies. Thus, in infancy, as in adulthood, features and conjunction relations appear to be processed by qualitatively different mechanisms.

Abstract
The availability of the Goto-Kakisaki (GK) rat model of non-insulin-dependent diabetes mellitus prompted us to test the effect of a limited period of undernutrition in previously diabetic young rats on their insulin secretion and insulin action during adult age. Four-week-old female GK rats were either food restricted (35% restriction, 15% protein diet) or protein and energy restricted (35% restriction, 5% protein diet) for 4 wk. Food restriction in the young GK rat lowered weight gain but did not aggravate basal hyperglycemia or glucose intolerance, despite a decrease in basal plasma insulin level. Furthermore, the insulin-mediated glucose uptake by peripheral tissues in the GK rat was clearly improved. We also found that food restriction, when it is coupled to overt protein deficiency in the young GK rat, altered weight gain more severely and slightly decreased basal hyperglycemia but conversely aggravated glucose tolerance. Improvement of basal hyperglycemia was related to repression of basal hepatic glucose hyperproduction, despite profound attenuation of basal plasma insulin level. Deterioration of tolerance to glucose was related to severe blunting of the residual glucose-induced insulin secretion. It is, however, likely that the important enhancement of the insulin-mediated glucose uptake helped to limit the deterioration of glucose tolerance.

Abstract
TNF-alpha is considered as one of the potential determinants of insulin resistance. However several data suggest that TNF-alpha expression itself, could be modulated by the degree of adiposity and/or plasma insulin levels. To clarify the determinants of plasma TNF-alpha levels in type 2 diabetes mellitus, we studied the impact of intensive insulin treatment on plasma TNF-alpha levels in 16 type 2 diabetic subjects with failure to oral antidiabetic medication (HbA1c: 10.8 +/- 1.2 %). Furthermore, we analyzed the relationship between plasma TNF-alpha levels and total or regional body fat measurements using anthropometry, bienergetic absorptiometry and computed tomography in a cohort of 33 caucasian obese type 2 diabetic subjects (BMI: 32.2 +/- 4.4 kg/m(2) ). The plasma TNF-alpha level was neither affected by plasma glucose level variations nor intensive insulin treatment despite a 37 % decrease in daily insulin needs at the end of insulin therapy (total duration: 11.5 +/- 2.0 days). The plasma TNF-alpha level was similar in men and women and unrelated to age, fasting glycemia or HbA1c. A relationship was highlighted with BMI (r =0.39, p <0.02), but not with total fat mass. This relationship was only dependent on the intra-abdominal fat mass amount as assessed by the waist-to-hip circumference ratio (r =0.52, p <0.01) and the visceral adipose tissue area (r =0.56, p <0. 01). These results show that plasma TNF-alpha levels are essentially dependent on visceral fat amount, thus suggesting that TNF-alpha could be one of the factors mediating insulin resistance and cardiovascular risk in obese type 2 diabetic patients.

Abstract
OBJECTIVE To get accurate measurements of visceral adipose tissue (VAT) using dual energy X-ray absorptiometry (DXA). DESIGN DXA and anthropometric data and their combinations were compared to the VAT area calculated from a computed tomography (CT) single scan. SUBJECTS 71 overweight subjects (44 women, 27 men), age: 16-70 y, BMI: 27-52 kg/m2. MEASUREMENTS Total body and segmental tissue composition, and new parameters obtained from DXA, in addition to waist and hip circumferences and abdominal sagittal diameter measurements. RESULTS The ratio measured at the umbilical level (sagittal diameter - subcutaneous fat width) x (transverse internal diameter)/(height) was closely related to VAT (r=0.94 for women and 0.88 for men). It gave the most predictive equation for VAT: y = 79.6x (s.e. 3.9) - 149 cm2 for the whole population (r2=0.86, P<0.0001, root mean square error=38.2 cm2. An independent relationship between lean mass or its index (r=0.52 and 0.72, P<0.001) and VAT was also found in women. CONCLUSION This study demonstrates the potential usefulness of DXA to supply accurate measurements of VAT in addition to total body composition determination in obese subjects.

Abstract
Monocytes play a pivotal role in the complex processes of inflammation, immunologic responses and atherothrombosis. Clinical studies essentially reported an increased procoagulant activity in diabetes and coronary disease, suggesting an overexpression of tissue factor. This was further confirmed by the direct measurement of tissue factor on monocyte membrane by flow cytometry. Many receptors can be measured on monocytes by flow cytometry: beta 2 integrins (CD 11 a-b-c/CD 18) involved in adhesion, EPR-1 receptor, receptors for advanced glycation products, urokinase receptor U-PAR. Flow cytometry allows a cell analysis in whole blood. Modern methods allow a standardization of the procedures and a quantification of the number of sites expressed by the cell. However, the respect of preanalytical and analytical conditions is mandatory to obtain reliable data. Besides, clinical studies in diabetes should carefully define the subgroups of patients: type of diabetes, metabolic abnormalities, risk factors, infective complications.

Abstract
An association between low birth weight and later impaired glucose tolerance was recently demonstrated in several human populations. Although fetal malnutrition is probably involved, the biological bases of such a relationship are not yet clear, and animal studies on the matter are scarce. The present study was aimed to identify, in adult (8-wk) female offspring, the effects of reduced protein and/or energy intake strictly limited to the last week of pregnancy. Thus we have tested three protocols of gestational malnutrition: a low-protein isocaloric diet (5 instead of 15%), with pair feeding to the mothers receiving the control diet; a restricted diet (50% of the control diet); and a low-protein restricted diet (50% of low-protein diet). Only the low-protein diet protocols, independent of total energy intake, led to a lower birth weight. The adult offspring female rats in the three deprived groups exhibited no decrease in body weight and no major impairment in glucose tolerance, glucose utilization, or glucose production (basal state and hyperinsulinemic clamp studies). However, pancreatic insulin content and beta-cell mass were significantly decreased in the low-protein isocaloric diet group compared with the two energy-restricted groups. Such impairment of beta-cell mass development induced by protein deficiency limited to the last part of intrauterine life could represent a situation predisposing to impaired glucose tolerance.

Abstract
Recent developments in dual-energy X-ray absorptiometry (DXA) have rendered feasible the determination of whole-body composition in small laboratory animals by directly measuring fat, fat-free and mineral bone masses. Our aim was to evaluate this technique by cross-calibrating the DXA method with the carcass chemical analysis in a heterogeneous population of nondiabetic Wistar and diabetic GK rats (21 animals were used for precision error and reproducibility determinations and 26 were used for accuracy studies). We report that this technique is optimized for weights >200 g. The respective CV for lean mass, fat mass and percentage of fat mass determined in short-term or transversal studies was 1.1 +/- 0.1, 3.0 +/- 1.3 and 3. 1 +/- 0.4% (mean +/- SD) respectively. Further, this technique is valid for rats weighing from 130 to 200 g by using three successive scans. In longitudinal studies, daily calibrations significantly increased the percentage of fat mass CV to 6.6 +/- 3.3%, but it was significantly decreased to 3.0 +/- 2.7% by the use of triplicate scans. The accuracy for DXA was excellent in reference to the chemical extraction technique (r2 = 0.95 for percentage of fat mass, P < 0.0001), using an adjustment factor of 0.75 (limits of agreement between the two methods for percentage of fat mass = -1.7-2.3%). Mimicry of longitudinal changes in body composition with intraperitoneal injections of saline solution demonstrated a satisfactory detection of body component changes (</=2% of error for each final component analyzed, when increasing total lean mass by 11. 8%). We conclude that DXA is appropriate for rat whole-body composition determination, allowing reliable long-term follow-up of individual animals for the first time.

Abstract
Leptin, a hormone produced by adipose tissue, is potentially involved in the regulation of adiposity. The effects of insulin and body fat distribution on human plasma leptin have not yet been clearly defined. The present study investigated the relationships between plasma leptin and total and regional body fat parameters measured by anthropometry and bienergetic absorptiometry associated or not with computed tomography, taking glucose metabolism into account. A cohort of 51 obese Caucasian women (23 with normal glucose tolerance, 11 with impaired glucose tolerance, and 17 with Type 2 diabetes) was analysed. All non-diabetic subjects had an oral glucose tolerance test together with plasma glucose and insulin measurements. Moreover, a subgroup of 7 diabetic subjects with failure to oral antidiabetic treatment was submitted to about 12 days of intensive subcutaneous insulin therapy. Plasma leptin was essentially dependent on total body fat mass (r = 0.83, p < 0.0001, for the whole population), but not related to adipose tissue distribution. An independent correlation between leptin adjusted on body fat mass and fasting insulinaemia (R = 0.72, p < 0.02) or C-peptide (R = 0.62, p < 0.03) was found significant only in the diabetic group. Insulin treatment was associated with a moderate and transient increase of plasma leptin. The relative variations of plasma leptin levels were strongly negatively correlated with those of free fatty acids. The present data confirm that plasma leptin is not dependent on body fat distribution and suggest an indirect effect of insulin on leptin secretion in clinical conditions.
