National Science Review 2024年第05期 72-86页

作者： Huifang E.Wang Paul Triebkorn martin Breyton Borana Dollomaja Jean-Didier Lemarechal Spase Petkoski Pierpaolo Sorrentino Damien Depannemaecker Meysam Hashemi Viktor K.Jirsa Aix Marseille Université Institut National de la Santéet de la Recherche Médicale Institut de Neurosciences des Systèmes(INS) UMR1106 Service de Pharmacologie Clinique et Pharmacosurveillance AP–HM

Virtual brain twins are personalized, generative and adaptive brain models based on data from an individual's brain for scientific and clinical use. After a description of the key elements of virtual brain twins,we present the standard model for personalized whole-brain network models. The personalization is accomplished using a subject's brain imaging data by three means:(1) assemble cortical and subcortical areas in the subject-specific brain space;(2) directly map connectivity into the brain models, which can be generalized to other parameters; and(3) estimate relevant parameters through model inversion, typically using probabilistic machine learning. We present the use of personalized whole-brain network models in healthy ageing and five clinical diseases: epilepsy, Alzheimer's disease, multiple sclerosis, Parkinson's disease and psychiatric disorders. Specifically, we introduce spatial masks for relevant parameters and demonstrate their use based on the physiological and pathophysiological hypotheses. Finally, we pinpoint the key challenges and future directions.

引用

Open Journal of Respiratory Diseases 2024年第2期14卷 39-50页

作者： Myriam Calle Rubio Olga de la Serna Blazquez José Luis R. martin Manuel Ruiz Cuetos Pulmonology Department Hospital Clínico San Carlos Madrid Spain Department of Medicine School of Medicine Universidad Complutense de Madrid Madrid Spain Instituto de Investigacion Sanitaria del Hospital Clínico San Carlos (IdISSC) Madrid Spain Pediatric Pulmonology Unit Pediatrics Department Hospital Universitario La Paz Madrid Spain Simplifying Research Institute Layos Spain Medical department in ITF Research Pharma S.L.U. Alcobendas Spain

Objective: This study aims to systematically examine the existing evidence regarding the clinical benefits of carbocysteine as an adjunctive treatment in acute bronchopulmonary and otorhinological processes. Design: Systematic review and meta-analysis. Data sources: An electronic search was conducted across PubMed, Cochrane Library, ***, and the European Clinical Trial Register, with the search dated to May 2023. Bibliographic references from other literature reviews and meta-analyses were also reviewed. The search was limited to randomized clinical trials published in any language and year. It was completed by cross-checking the references of the located articles. Methods: Inclusion criteria covered studies assessing systemic or inhaled carbocysteine, regardless of dosing regimen. Concomitant medication use was acceptable if balanced between intervention and control groups. Authors independently extracted data, resolving disagreements through consensus. Methodological quality assessment relied on critical reading of each study. Dichotomous variables were analyzed using odds ratio (OR), and a final effect size was calculated. Statistical significance was established when confidence intervals did not cross the neutral value. Heterogeneity was assessed via the X2 test and I2 index. Results: Out of 318 initially identified studies, 4 met inclusion criteria. The meta-analysis for poor general condition yielded an OR of 0.45 in favor of intervention, p = 0.013, with non-significant heterogeneity. Cough events showed a percentage of 15.8% for carbocysteine vs. 27.2% for placebo. On the seventh day, expectoration rates were 18.37% for carbocysteinevs 33.3% for placebo. Conclusions: The observed clinical benefits align with carbocysteine’s mucoactive and muco-regulatory properties, complemented by anti-inflammatory and antioxidant actions. Carbocysteine stands out among mucolytic agents. In the context of persistent infectious diseases,

Preparation and Characterisation of Corncob-Based Biosorbents in Côte d’Ivoire

引用

Advances in Materials Physics and Chemistry 2024年第8期14卷 178-195页

This study focuses on the preparation of corncob-based biosorbents. The chemical impregnation method was used to vary the chemical agent namely phosphoric acid H3PO4 (BA) and sodium hydroxide NaOH (BB). The physicochemical analysis of the two biosorbents indicated that under the same preparation conditions, the bio-sorbents have after activation yields lower than 50% (24.37% for BB and 49.09% for BA). In addition, the biosorbents have iodine index values between 444.17 mg/g and 418.79 mg/g and specific surfaces related to the adsorption of methylene blue ranging from 18.54 m2/g to 19.70 m2/g. The study of surface functional groups by using the Boehm test and pH zero point charge (pHPZC) confirmed the acidic nature of BA and BB biosorbents with respective values pHPZC = 4.01 and pHPZC = 4.90. The Langmuir method and BET analysis determined the specific surface areas by liquid phase adsorption of methylene blue as well as the porosity. The BET surface areas of BA and BB obtained are 72.01 m2/g and 63.10 m2/g respectively. The influence of the chemical activating agent on the formation of pores was confirmed by electron microscopy (SEM) analysis. From this study, it is found that the best activating agent for corn cobs was found to be phosphoric acid because the BA biosorbent was revealed to be the most favourable due to its surface area and good pore volume which are high compared to sodium hydroxide NaOH. Moreover, their application as adsorbent for effluent treatment could be explored.

The Lom Pangar dam, the largest reservoir in Cameroon with a storage capacity of 6 km3 and a 30 MW hydropower plant, primarily regulates the hydrologic regime of the Sanaga River to maintain hydropower efficiency during dry seasons and enhance downstream hydropower plant performance. Understanding and managing sediments are crucial for the sustainability of dams, as indicated by numerous studies. This study assessed the granulometry of the sediments transported across the reservoir. For that purpose, 6 samples of fresh sediments were collected in the lacustrine and transitional sections of the reservoir using the standard method. Particles size was assessed using the laser diffusion technic after a 3 mm sieving. Various granulometric parameters were derived from the literature to analyze and characterize those sediments. Results show that silts are more than 70% of particles size and range between 2.19 - 60.26 µm. Size distribution also shows the same trend with D75 less than 51 µm. This is confirmed by the low values of Inman Skewness SkΦ (−0.168 to 0.303). The Sorting index S0 ranges from 0.31 to 0.53 µm, showing a very well-sorted sediments, aligning with low values of Krumbein index (0.906 - 1.683) that express the low heterometry of the particles. The consequence on the dam will be a quick clogging of the bottom of the reservoir. Their pH varies from 7.0 to 7.5. It also appears that the sandy fraction trend is higher in the right bank of the dam and reaches 22% on the right bank of Pangar River due to crystalline geology. Fraction greater than 3000 µm is negligible. The management of the dam has to keep attention to these results as siltation may close the safety outlet of the dam, damage turbines, and provoke recurrent technical and safety issues. Further, the clogging of the bottom of the reservoir may lead to an ecological problem with the limitation of hyporheic flow. Thus, water exchange with the underground water table and the natural purification of wate

Klingsor Syndrome: An Observation in a Patient with Schizophrenia

引用

Open Journal of Urology 2024年第5期14卷 346-351页

作者： Mbuya Musapudi Eric Ouake Hadidjatou Michel Agounkpe Yevi Dodji Magloire Inès Hodonou Fred martin Avakoudjo Josué Georges Dejinnin Department of Urology and Andrology Hubert Koutoukou Maga National Teaching Hospital Cotonou Benin Department of Surgery University Clinics of Lubumbashi Lubumbashi Democratic Republic of the Congo

Background: Klingsor syndrome refers to genital self-mutilation in man following delusional religious beliefs. Later, Schweitzer proposed expanding the term to include all psychotic disorders, drug and alcohol abuse. Apart from the noted hemorrhagic emergency and difficult surgical operation, there is a psychosocial impact, sexual and urinary complications (stenosis, urethral fistula) which make this pathology complex. Aim: The Aim of this study is to describe the clinical case of Klingsor syndrome and evaluate its management in light of the literature. Case Presentation: We report a rare case of genital self-mutilation in a 35-year-old man, non-compliant schizophrenic, received 04 days after the trauma and whose treatment consisted of remodeling of the penis stump and follow-up by psychiatrists. Conclusion: Klingsor syndrome is a rare but serious phenomenon. Its management remains complex, but it must be early and multidisciplinary.
