Introduction: Biometrics therefore corresponds to the measurement of the morphological elements of humans. One of the most common ultrasound requests by clinicians is the assessment of liver size. The aim of our study was to study liver biometry using ultrasound in healthy adult subjects. Material and Methods: This was a prospective, descriptive and analytical study, carried out at CHU Point-G over a period of 7 months. A liver ultrasound was performed on 100 individuals without lesions, by a doctor in his final year of specialization in radiology and medical imaging. For each subject, we determined the height and anteroposterior diameter of the right liver and the left liver. Results: The mean age was 39.05 ± 16.86 years. The body mass index (BMI) 18.5 - 24.9 group was the most represented with 58%. The mean height of the right liver was 138.40 ± 14.85 mm. It was 136.81 ± 14.70 mm in men and 139.92 ± 14.99 mm in women (P = 0.306). That of the left liver was 95.55 ± 14.34 mm, in men, it was 91.79 ± 13.51 mm and 99.16 ± 14.31 mm in women (P = 0.019). We found a significant correlation between right liver height and BMI (P = 0.013). Conclusion: The mean values of liver biometry were established in our series. There was a significant correlation between right liver height and BMI. Liver ultrasound remains a reliable technique for liver biometry.

Aim: This study aimed at describing the anatomical variations of the external branch of the superior laryngeal nerve and at estimating the frequency of nerves at risk during the thyroid surgery. Methodology: We realized a forward-looking study from September, 2016 in May 31st, 2018 in the laboratory of anatomy of the Faculty of Medicine and Odontostomatology of Bamako in Mali. All the fresh anatomical subjects not carrying trauma and or a scar at the level of the previous region of the neck were held. The anatomical subjects were not included presenting a traumatic lesion and\or a scar of the previous region of the neck. Results: We realized 34 dissections of the external branch of the superior laryngeal nerve to 17 deathly subjects (11 men and 6 women with a sex-ratio of 1.8). The average age of the subjects was of 42 years (extremes: 18 and 70 years). Our study allowed highlighting in 100% of the cases, the external branch of the superior laryngeal nerve and the superior thyroid artery so to the right as to the left. On 34 dissected external branch of the superior laryngeal nerve, none had a previous route. However we found 28 nerves (82.4%) having a later route, stuck to the external face of the lower constrictor of the pharynx. These were not mixed with the superior thyroid artery and its branch of division and were situated outside the thyroid capsule. In 17.6% of the cases (6 cases), the nerve had a route mixed in the branch of the superior thyroid artery. These were found inside of the capsule (11.8% adhered to the artery and 5.8% crossed its branch of division). Conclusion: The risk of injury of the external laryngeal nerve during thyroid surgery procedure is never zero. It is more important on the left side.

Introduction: Radiology and medical imaging examinations bring together the means of acquiring and restoring images of the human body from different physical phenomena such as the absorption of X-rays, nuclear magnetic resonance, reflection of ultrasound waves or radioactivity, with which we sometimes associate optical imaging techniques such as endoscopy. The objective of our study was to study the profile of radiological examinations in the radiology and medical imaging department of the “KALALE” medical clinic. Methodology: This was a descriptive, prospective study that took place over a period of six (6) months in the radiology and medical imaging department of the “KALALE” medical clinic and the centers of health of communes III and IV of Bamako in Mali. Data collection was carried out on a survey form. The parameters studied were sociodemographic data, clinical data, radiological data. Results: We recorded 6030 radiology examinations of which 19% of the examination frequency cases came from the “KALALE” medical clinic and 81% of the cases were referrals from the reference health centers of communes III and IV. There were 1500 X-rays or 24.9% of cases including 54% cases of bone X-rays;5% of cases of skull and face X-rays;5% of cases of Intravenous Urography (IVU);4% of cases of Hysterosalpingography (HSG);3% of cases of Retrograde Ureterocystography (UCR) and 1% of cases of X-ray of the Abdomen without preparation (ASP). We found 4530 ultrasounds or 75.1% of cases. Conclusion: Medical imaging has become essential in the study of the human body and now constitutes an essential tool for the detection and treatment of most pathologies, from simple fractures to the most serious tumors.

Non-isothermal Decomposition Mechanism and Kinetics of LiClO_4 in Nitrogen

引用

Chemical Research in Chinese Universities 2010年第2期26卷 300-303页

作者： diakite Kahirou College of Chemistry and Molecular Sciences Wuhan University

The non-isothermal decomposition kinetics of LiClO4 in flow N2 atmosphere was studied. TG-DTA curves show that the decomposition proceeded through two well-defined steps below 900℃, and the mass loss was in agreement with the theoretical value. XRD profile demonstrates that the product of the thermal decomposition at 500℃ is LiCI. For the decomposition kinetics study, the activation energies calculated with the Friedman method were considered as the initial values for non-linear regression and were used for verifying the correctness of the fired models. The decomposition process was fitted by a two-step consecutive reaction： extended Prout-Tompkins equation[Bna, f（α） is （1-α）^nα^α] followed by a lth order reaction（F1）. The activation energies were （215.6±0.2） and （251.6±3.6） kJ/mol, respectively. The exponentials n and a for Bna reaction were （0.25±0.05） and （0.795±0.005）, respectively. The reaction types and activation energies were in agreement with those obtained from the isothermal method, but the exponentials were optimized for better firing and prediction.

Simultaneous thermogravimetry-differential thermal analysis （TG-DTA） was used to study the kinetics and the degradation of magnesium salicylate（ C14H10MgO6 ） in air. The results show that the decomposition proceeds through two steps. The kinetics of the first decomposition step was studied. The activation energies were calculated by using the Friedman and Flynn Wall Ozawa（FWO） methods, and the most probable kinetic model function was estimated using the multiple linear regression method. The values of the correlated kinetic parameters for the first decomposition step are E = 152.97 kJ/mol, lg（A/S^-1 ） = 10. 78, f（α） = （ 1 - α）^n（ 1 ＋Kcatα）, n =0. 691, and Kcat = 1. 3048.

This study focused to determine the bacteriological quality of different commonly used water sources, including boreholes, hand pumps, surface water, household containers, dug well and cement reservoirs in Pelengana commune, in Mali with special reference to the internally displaced people camps. Four hundred and eight water samples were collected from different sites and sources, from July 2016 to June 2017. Water samples were examined for total coliform, fecal coliform and fecal enterococci counts using the most probable number method. Also, samples were investigated for the presence of enteric bacteria isolated, namely Escherichia coli, Enterococcus fecalis, Bacillus, Citrobacter and Enterobacter. Results revealed that the three indicators bacteria (Total Coliform (48.7%), Fecal Coliform (100%), and Fecal enterococci (37.01%)) were found above permissible limit for drinking water. The highest number of the indicators bacteria found was 1800 TC/100ml water. Enteric bacteria isolated were Escherichia coli (25.7%), Enterococcus fecalis (21.91%), Bacillus (16.72%), Enterobacter (4.56%) and Citrobacter (3.91%). The most contaminated water source was surface water (15.28%) followed by household containers (13.65%), boreholes (8.75%), cement reservoirs (7.47%), hand pumps (5.31%) and dug wells (2.7%). These findings illustrate that contamination varied with seasons, and the highest level was observed in rainy season (30.02%) compared to the dry season (23.14%). All sources of water in the study sites were contaminated. It is suggested that the outright prevention of surface water consumption should be employed and monitoring of the quality of water resources is needed.
