International audience; The purpose of this study was to investigate the relationships between maximal half-squat strength and bone variables in a group of young overweight men. 76 young overweight men (18 to 35 years) voluntarily participated in this study. Weight and height were measured, and body mass index (BMI) was calculated. Body composition, bone mineral content (BMC) and bone mineral density (BMD) and geometric indices of hip bone strength were determined for each individual by Dual-energy X-ray absorptiometry (DXA). Maximal half-squat strength was measured by a classical fitness machine (Smith machine) respecting the instructions of the national association of conditioning and muscular strength (NCSA). Maximal half-squat strength was positively correlated to WB BMC (r = 0.37; p < 0.01), WB BMD (r = 0.29; p < 0.05), L1–L4 BMC (r = 0.43; p < 0.001), L1–L4 BMD (r = 0.42; p < 0.001), TH BMC (r = 0.30; p < 0.01), TH BMD (r = 0.26; p < 0.05), FN BMD (r = 0.32; p < 0.01), FN cross-sectional area (CSA) (r = 0.44; p < 0.001), FN cross-sectional moment of inertia (CSMI) (r = 0.27; p < 0.05), FN section modulus (Z) (r = 0.37; p < 0.001) and FN strength index (SI) (r = 0.33; p < 0.01). After adjusting for lean mass, maximal half-squat strength remained significantly correlated to WB BMC (p = 0.003), WB BMD (p = 0.047), L1–L4 BMC (p < 0.001), L1–L4 BMD (p < 0.001), TH BMC (p = 0.046), FN BMD (p = 0.016), FN CSA (p < 0.001), FN Z (p = 0.003) and FN SI (p < 0.001). The current study suggests that maximal half-squat strength is a positive determinant of BMC, BMD and geometric indices of hip bone strength in young overweight men.

International audience; The aim of this study was to explore the relationships between performances obtained in different physical tests and bone parameters (bone mineral density [BMD], bone mineral content, hip geometry indices, and trabecular bone score [TBS]) in a group of young Lebanese overweight and obese adult men. Fifty-two overweight and/or obese (body mass index > 25 kg/m2) young men whose ages range from 18 to 35 yr participated in this study. Weight and height were measured, and body mass index was calculated. Body composition, BMD, cross-sectional area and section modulus (Z) of the femoral neck (FN), and TBS were measured by dual-energy X-ray absorptiometry. Maximum oxygen consumption (VO2 max, in liter per minute) was determined by direct measurement while exercising on a medical treadmill. One-repetition-maximum half-squat and maximum power (P max) of the lower limbs were measured using validated exercises. Lean mass was a positive determinant of whole-body bone mineral content (r = 0.71, p

6th International Work-Conference on Bioinformatics and Biomedical Engineering (IWBBIO), Granada, SPAIN, APR 25-28, 2018; International audience; The aim of this study was to compare Trabecular Bone Score (TBS) in overweight and normal-weight young women. This study included 14 overweight (BMI > 25 kg/m(2)) and 42 normal-weight (BMI < 25 kg/m(2)) young Lebanese women whose ages range from 18 to 32 years. Body composition, Bone Mineral Content (BMC), Bone Mineral Density (BMD), and lumbar spine (L1-L4) TBS were assessed by dual-energy X-ray asborptiometry (DXA). The DXA measurements were completed for the whole body (WB), the lumbar spine (L1-L4), the total hip (TH) and the femoral neck (FN). Physical activity, daily calcium intake, daily protein intake and sleep quality index were evaluated using validated questionnaires. Maximal oxygen consumption (VO2 max in l/mn) was measured whilst exercising on a bicycle ergometer using a specialized device. Weight, height, BMI, lean mass, fat mass, WB BMC, WB BMD, TH BMD and FN BMD were significantly higher in overweight women compared to normal-weight women. Trabecular Bone Score (TBS) was not significantly different between the two groups (overweight and normal-weight). In the whole population (n = 56), weight, height, BMI, lean mass and fat mass were positively correlated to BMC and BMD values but not to TBS values. VO2 max (l/mn) was positively correlated to BMC, BMD and TBS (p < 0.05). This study suggests that being overweight is not associated with higher trabecular bone score values in young women.

The aim of this study was to explore the relationship between maximal oxygen consumption (VO2 max; mL/mn/kg) and composite indices of femoral neck strength in a group of young women. 41 young women whose ages ranged from 18 to 35 years participated in the present study. Femoral neck bone mineral density was measured by DXA. Composite indices of femoral neck strength (CSI, BSI and ISI) were calculated. VO2 max (mL/mn/kg) of the participants was measured using a Cosmed Fitmate pro device (version 2.20) while exercising on a bicycle ergometer (Siemens-Elema RE 820; Rodby Elektronik AB, Enhorna, Sweden). VO2 max (mL/mn/kg) was positively correlated to CSI (r = 0.52; p < 0.001) and ISI (r = 0.45; p < 0.01). The positive associations between VO2 max (mL/mn/kg) and these two indices (CSI and ISI) remained significant after controlling for body mass index using multiple linear regression models.

Opinion mining in Arabic is a challenging task given the rich morphology of the language. The task becomes more challenging when it is applied to Twitter data, which contains additional sources of noise, such as the use of unstandardized dialectal variations, the non-conformation to grammatical rules, the use of Arabizi and code-switching, and the use of non-text objects such as images and URLs to express opinion. In this paper, we perform an analytical study to observe how such linguistic phenomena vary across different Arab regions. This study of Arabic Twitter characterization aims at providing better understanding of Arabic Tweets, and fostering advanced research on the topic. Furthermore, we explore the performance of the two schools of machine learning on Arabic Twitter, namely the feature engineering approach and the deep learning approach. We consider models that have achieved state-of-the-art performance for opinion mining in English. Results highlight the advantages of using deep learning-based models, and confirm the importance of using morphological abstractions to address Arabic's complex morphology. 2017 Association for Computational Linguistics This work was made possible by NPRP 6-716-1-138 grant from the Qatar National Research Fund (a member of Qatar Foundation).

Introduction The aim of this study was to explore the relationships between performances obtained in different physical tests and bone parameters (bone mineral density (BMD) and bone mineral content (BMC)) in a group of young Lebanese adults. Methods One hundred and six young Lebanese adults (45 women and 61 men) whose ages range from 17 to 34 years participated in this study. Weight and height were measured, and body mass index (BMI) was calculated. Daily calcium intake, daily protein intake and physical activity level (h/week) were evaluated using validated questionnaires. The level of physical performance was measured using several physical tests: vertical-jump test, standing long jump test, 3-jumptest, 5-jump-test and 1-RM half-squat. Body composition, bone mineral content (BMC) and BMD at whole body (WB), lumbar spine (L2-L4), total hip (TH) and femoral neck (FN) were measured by dual-energy X-ray absorptiometry (DXA). Results In women, height, lean mass, 1- RM half-squat and performances obtained in three physical tests (vertical jump test, 5-jump-test and 1-RM halfsquat) were positively correlated to BMD and BMC. In men, lean mass and 1-RM half-squat were positively correlated to BMD and BMC. Conclusion This study suggests that lean mass and maximum strength obtained in half-squat are positively correlated to BMD in young adults.

A clinical program in liver transplantation was begun at UCLA in 1984 after a period of laboratory investigation. The first 100 orthotopic liver transplants (OLT) were performed in 83 patients (43 adults and 40 children) between February 1, 1984 and November 1, 1986. Donors and recipients were matched only for size and ABO blood group compatibility, with OLT performed across blood groups in 28 patients. Standard operative techniques were used, including venous-venous bypass in adults. Arterial reconstruction was performed using an aortic Carrel patch or "branch patch" in 65% of cases and by end-to-end or aortic conduit techniques in the remainder. The hepatic artery thrombosis rate was 5%. Biliary reconstruction was choledochocholedochostomy in 67 OLT and Roux-en-Y choledochojejunostomy in 33 (complication rate of 24% and 24%, respectively). Average lengths and ranges of donor liver ischemia, operating time, and blood replacement were 4 hours (range: 1-10 hours), 7.6 hours (range: 4-15 hours), and 17 units packed cells (range: 2-220 units). Immunosuppressive regimen was cyclosporine-steroid combination, with monoclonal anti-T-cell antibody (OKT3) used for refractory rejection. All patients had one or more complications: pulmonary (78%), infectious (51%), renal dialysis (25%), neurologic (22%). All patients had at least one episode of acute rejection, and 3.6% had chronic rejection. Retransplantation was needed in nine patients once and in four patients twice. The overall retransplant survival rate was 54%, and two of four patients who received a second retransplant are alive. Sixty-three of the 83 patients (76%) are alive (adults 72%, children 80%). The 1- and 2-year actuarial survival rate is 73% (adults 68%, children 78%). Thirty-eight of 43 patients (88%) who had transplantation in the past year are alive. Of 14 perioperative variables assessed as predictors of early mortality, only postoperative dialysis (p less than 0.0005) and presence of severe rejection (p less than 0.01) had statistical significance. Seventy per cent of adults returned to work, and 84% of children had normal or accelerated growth. A new program in liver transplantation provides a dramatic option in patient care and an academic stimulus to the entire medical center.
