    Introduction: Bilateral ingual hernia (HIB) is a public health problem, for which there is currently no preventive treatment, the only alternative is surgical treatment. The spread and generalization of the use of prostheses to treat adult groin hernias has led to a drop in post-operative complications and, in particular, recurrences (˂1%) and offers a better quality of life. The objective of our study is to evalue the post-operative outcomes and quality of life of patients after prosthetic HIB repair in a single step. Patients and Method: Our study involves a series of 84 patients with HIB in a descriptive study with prospective follow-up. Patients were recruited in the surgery department of CHU BENI MESSOUS, ALGIERS. The study was conducted over a five-year period. The main criterion for judgment was the following two-year operating positions and the secondary criteria, quality of life, duration of the intervention, length of stay. Rating scales: EVAD and DN4 and CCS. Results: No loss of sight or death was reported. The average age of the patients was 61.5±12 years, exclusively male. Eighty-one (96.43%) patients had primary HIB and three (3.57%) had recurrence. Surgery was performed under rachianesthesia in 74% of cases and 26% of cases under general anesthesia. The average duration of the procedure was 2.5 H ± 25 min. The average length of hospital stay was 1.4±1 days. Immediate post-operative follow-up was marked by two cases of parietal hematoma (2%). One case (2.4%) of bilateral fistula was noted at 6 months and 12 months post-operative. There were no cases of recurrence, discomfort or chronic pain at the end of the 24-month assessment. Conclusion: In the light of our work, it emerges that the prosthetic repair of an HIB in a single step had a low rate of recurrence, very low mortality, patient comfort and low economic cost.ntroduction : la hernie inguinale bilatérale (HIB) représente un problème de santé publique, auquel il n’existe actuellement aucun traitement préventif, la seule alternative réside dans le traitement chirurgical. La diffusion et la généralisation de l’utilisation des prothèses pour traiter les hernies de l’aine de l’adulte ont entrainé une chute des complications postopératoires et notamment, les récidives (˂1%) et offre une meilleure qualité de vie. L’objectif de notre étude est d’évaluer les suites postopératoires et la qualité de vie des patients après une réparation prothétique d’une HIB en un seul temps. Patients et méthode: Il s’agit d’une étude descriptive par un suivi prospectif de 84 patients présentant une HIB. Les patients étaient recrutés au sein de la consultation des services de chirurgie du CHU BENI MESSOUS, ALGER. L’étude s’est déroulée sur une période de cinq ans. Le critère de jugement principal était les suites postes opératoires à deux ans et les critères secondaires, la qualité de vie, la durée de l’intervention et la durée de séjour. L’échelles d’évaluation : EVAD et DN4 et CCS. Résultats : Aucun perdu de vue ni aucun décès n’a été enregistré. L’âge moyen des patients était de 61,5±12 ans, exclusivement de sexe masculin. Quatre-vingt-un (96,43%) patients avaient une HIB primaire et trois (3,57%) récidivée. L’intervention chirurgicale était réalisée sous rachianesthésie dans 74% des cas et 26% des cas sous anesthésie générale. La durée moyenne de l’intervention était de 2,5 H ± 25 mn. La durée moyenne du séjour hospitalier était 1,4±1 jours. Les suites postopératoires immédiates étaient marquées par deux cas d’hématome pariétal (2%). Un cas (2,4%) de fistules bilatérale était notée à 6 mois et à 12 mois du postopératoire. Nous n’avons recensé aucun cas de récidive, ni gêne ni douleur chronique au terme de l’évaluation à 24 mois. Conclusion : A la lumière de notre travail, il en ressort, que la réparation prothétique d’une HIB en un seul temps avait un faible taux de récidive, très faible morbi-mortalité, un bon confort du patient et un faible coût économiqu

    La maladie de Crohn (MC) est une maladie inflammatoire transmurale du tube digestif d’évolution chronique, d’étiologie probablement multifactorielle. Elle touche l’adulte jeune entre 30 et 40 ans. La localisation la plus fréquente est le grêle distale avec des formes grêliques pures dans 30 à 40% et des formes grêlo-coliques dans 20 à 30%, la maladie de Crohn se traduit par des douleurs abdominales et des diarrhées qui peuvent persister plusieurs semaines. L’iléo-coloscopie avec biopsies est primordiale pour confirmer son diagnostic. Le traitement doit toujours être médical en dehors des situations d’urgences qui peuvent imposer des gestes chirurgicaux : drainage d’abcès, traitement des occlusions et des péritonites, La place de la laparoscopie dans la maladie de Crohn est faisable mais les résultats dépendent de l’expérience de l’opérateur.AbstractCrohn's disease (CD) is a chronic transmural inflammatory disease of the digestive tract, probably of multifactorial etiology. It affects young adults between the ages of 30 and 40. The most frequent localization is the distal hail with pure hail forms in 30 to 40% and hail-colonic forms in 20 to 30%. Crohn's disease results in abdominal pain and diarrhea which can persist for several weeks. Ileo-colonoscopy with biopsies is essential to confirm its diagnosis. The treatment must always be medical apart from emergency situations which may require surgery: abscess drainage, treatment of occlusions and peritonitis, the place of laparoscopy in Crohn's disease is feasible but the results depend on the operator’s experience.Keywords: Crohn's disease, Complications, Ileocecal resection, Recurrence. &nbsp

    Pupil Dilation Is Sensitive to Semantic Ambiguity and Acoustic Degradation

    © The Author(s) 2020. Speech comprehension is challenged by background noise, acoustic interference, and linguistic factors, such as the presence of words with more than one meaning (homonyms and homophones). Previous work suggests that homophony in spoken language increases cognitive demand. Here, we measured pupil dilation—a physiological index of cognitive demand—while listeners heard high-ambiguity sentences, containing words with more than one meaning, or well-matched low-ambiguity sentences without ambiguous words. This semantic-ambiguity manipulation was crossed with an acoustic manipulation in two experiments. In Experiment 1, sentences were masked with 30-talker babble at 0 and +6 dB signal-to-noise ratio (SNR), and in Experiment 2, sentences were heard with or without a pink noise masker at –2 dB SNR. Speech comprehension was measured by asking listeners to judge the semantic relatedness of a visual probe word to the previous sentence. In both experiments, comprehension was lower for high- than for low-ambiguity sentences when SNRs were low. Pupils dilated more when sentences included ambiguous words, even when no noise was added (Experiment 2). Pupil also dilated more when SNRs were low. The effect of masking was larger than the effect of ambiguity for performance and pupil responses. This work demonstrates that the presence of homophones, a condition that is ubiquitous in natural language, increases cognitive demand and reduces intelligibility of speech heard with a noisy background

    In this work, a comparative study of the sensor response of single walled carbon nanotubes (SWCNTs) and reduced graphene oxide (rGO) covalently and non-covalently functionalised with1-[N-(2-ethoxyethyl)-4-pentynamide]-8(11),15(18),22(25)-tris-{2-[2-(2-ethoxyethoxy) ethoxy]-1-[2-((2-ethoxy ethoxy)-ethoxy)methyl]ethyloxy}zinc(II) phthalocyanine (ZnPc) to ammonia is carried out. It was shown that in the case of SWCNT-based materials both covalent and non-covalent functionalisation with zinc(II) phthalocyanine leads to the increase of the sensor response toward NH3, while functionalisation of reduced graphene oxide causes a decrease in the response. At the same time both covalent and non-covalent linking of zinc(II) phthalocyanine leads to twofold decrease of the sensor recovery times. The sensor response of the carbon nanomaterial (single walled carbon nanotubes or reduced graphene oxide) hybrids covalently functionalised with zinc(II) phthalocyanine is several times higher than in the case of non-covalent linking of zinc(II) phthalocyanine to these nanomaterials, which is in good correlation with the number of zinc(II) phthalocyanine molecules adsorbed onto the SWCNT and rGO walls. © 2017 Elsevier B.V

    It has been found a linear progression between the panel temperature and its efficiency. A novel cellulose pad arrangement, which is saturated with water, at back surface of photovoltaic panel for cooling has achieved better results. The experimental results showed a reduction in maximum PV panel temperature at using the proposed water cooling system. The average temperature of the PV panel dropped 10.1°C and an increase in average solar panel efficiency about 20.8% during operating time. Then, a comparison between the PV panel results cooling by natural convection and using the proposed water cooling system will reveal the most efficient

    There is a need for improved understanding of how different cerebrovascular reactivity (CVR) protocols affect vascular cross-sectional area (CSA) to reduce error in CVR calculations when measures of vascular CSA are not feasible. In human participants, we delivered ∼±4 mm Hg end-tidal partial pressure of CO2 (PETCO2) relative to baseline through controlled delivery, and measured changes in middle cerebral artery (MCA) CSA (7 Tesla magnetic resonance imaging (MRI)), blood velocity (transcranial Doppler and Phase contrast MRI), and calculated CVR based on a 3-minute steady-state (+4 mm Hg PETCO2) and a ramp (-3 to +4 mm Hg of PETCO2). We observed that (1) the MCA did not dilate during the ramp protocol (slope for CSA across time P \u3e 0.05; R2 = 0.006), but did dilate by ∼7% during steady-state hypercapnia (P \u3c 0.05); and (2) MCA blood velocity CVR was not different between ramp and steady-state hypercapnia protocols (ramp: 3.8 ± 1.7 vs. steady-state: 4.0 ± 1.6 cm/s/mm Hg), although calculated MCA blood flow CVR was ∼40% greater during steady-state hypercapnia than during ramp (P \u3c 0.05) with the discrepancy due to MCA CSA changes during steady-state hypercapnia. We propose that a ramp model, across a delta of -3 to +4 mm Hg PETCO2, may provide an alternative approach to collecting CVR measures in young adults with transcranial Doppler when CSA measures are not feasible. Novelty: We optimized a magnetic resonance imaging sequence to measure dynamic middle cerebral artery (MCA) cross-sectional area (CSA). A ramp model of hypercapnia elicited similar MCA blood velocity reactivity as the steady-state model while maintaining MCA CSA

    In the present work, we study and compare the structure and sensing properties of thin films of unsubstituted palladium phthalocyanine (PdPc) and hexadecafluorosubstituted palladium phthalocyanine (PdPcF16). Thin films of PdPc and PdPcF16 were obtained by the method of organic molecular beam deposition and their structure was studied using UV-visible spectroscopy, X-ray diffraction and atomic force microscopy techniques. The electrical sensor response of PdPc films toward ammonia and hydrogen was investigated and compared with that of PdPcF16 films. The nature of interaction between the phthalocyanines films and some gaseous analyte molecules has been clarified using Quantum chemical (DFT) calculations

    Zinc sulphide (ZnS) thin films with both n- and p-type electrical conductivity were grown on glass/fluorine-doped tin oxide-conducting substrates from acidic and aqueous solution containing ZnSO4 and (NH4)2S2O3 by simply changing the deposition potential in a two-electrode cell configuration. After deposition, the films were characterised using various analytical techniques. X-ray diffraction analysis reveals that the materials are amorphous even after heat treatment. Optical properties (transmittance, absorbance and optical bandgap) of the films were studied. The bandgaps of the films were found to be in the range (3.68–3.86) eV depending on the growth voltage. Photoelectrochemical cell measurements show both n- and p-type electrical conductivity for the films depending on the growth voltage. Scanning electron microscopy shows material clusters on the surface with no significant change after heat treatment at different temperatures. Atomic force microscopy shows that the surface roughness of these materials remain fairly constant reducing only from 18 nm to 17 nm after heat treatment. Thickness estimation of the films was also carried out using theoretical and experimental methods. Direct current conductivity measurements on both as-deposited and annealed films show that resistivity increased after heat treatment
