Open Journal of Medical Psychology 2024年第3期13卷 39-57页

This comprehensive review explores the intricate dynamics between psychosocial factors and chronic wound healing processes, specifically focusing on prevalent conditions such as pressure ulcers, diabetic foot ulcers, and venous leg ulcers. By examining the roles of psychiatric conditions, including depression, anxiety, and post-traumatic stress disorder (PTSD), this paper illuminates how these factors intricately influence wound healing dynamics, including mechanisms of pain perception and inflammatory responses. Furthermore, we evaluate the effectiveness of integrated biopsychosocial interventions, which encompass a holistic approach to wound care, thereby enhancing healing outcomes for dermatology patients. Future studies should focus on investigating the specific psychosocial determinants that significantly influence wound healing, exploring novel therapeutic strategies, and implementing personalized interventions to meet the unique needs of each patient. Such endeavors hold promise in advancing the fields of psychodermatology and wound management, fostering a deeper understanding and application of psychosocial considerations in dermatological care.

Preliminary Palynostratigraphic Data on the Middle Albian-Lower Cenomanian of the Tarfaya Basin, Southwest Morocco

引用

Open Journal of Geology 2024年第4期14卷 548-568页

作者： Khaoula Chafai Touria Hssaida Wafaa Maatouf Mohamed Z. Yousfi sara Chakir Soukaina Jaydawi Hanane Khaffou Department of Geology Faculty of Sciences Ben M&#8217Sik University Hassan II Casablanca Morocco Department of Petroleum Laboratory Office National des Hydrocarbures et des Mines Rabat Morocco Department of Geology Faculty of Sciences Dhar El Mahraz Sidi Mohamed Ben Abdellah University Fes Morocco Department of Geology Faculty of Sciences Mohammed V University Rabat Morocco

The Tarfaya-Laayoune-Boujdour basin is of great interest to oil exploration;on this aspect, there has been exploration by the Moroccan National Office of Hydrocarbons and Mining, which has shown indices of oil and/or gas recorded in most wells drilled in the Moroccan Atlantic margin. FD-1 well, object of this study, is one of these wells located in the offshore Tarfaya-Laayoune-Boujdour basin. A palynological examination of the processed samples revealed the existence of organic palynomorphs, well conserved and rich in dinoflagellate cysts. The latter are composed of worldwide marker taxa of high stratigraphic resolutions. Thus, the middle upper Albian (3408 - 3408.5 m) is determined by the presence of Cribroperidinium tensiftense, Tehamadinium coummia, Spiniferella cornuta, Chichaouadinium vestitum, Dinopterygium alatum and Litosphaeridium arundum. The upper Albian (3406.5 - 3408 m) is characterized by the FOs of marker taxa: Cyclonephelium chabaca, Cribroperidinium auctificum and Chichaouadinium vestitum. Lastly, the upper Albian-lower Cenomanian transition is defined between 3404 m and 3406.50 m, as suggested by the FOs of Chichaouadinium boydii, Dinopterygium tuberculatum, Sepispinula ancorifera, Litosphaeridium conispinum, Prolixosphaeridium conulum and Xenascus ceratioides.

Primary Hyperoxaluria Type 1 in Adulthood: Case Series

Open Journal of Nephrology 2024年第3期14卷 350-360页

作者： sara El Maakoul Nada El Kadiri Nabil Hmaidouch Salma Belmokadem Loubna Benamar Tarik Bouattar Naima Ouzeddoun Department of Nephrology Dialysis Renal Transplantation Ibn Sina University Hospital-Rabat Rabat Morocco Faculty of Medicine and Pharmacy Mohammed V University Rabat Morocco

Introduction: Primary hyperoxaluria type 1 (HP1) is a rare lithiasis with systemic involvement, due to the accumulation of calcium oxalate crystals. In the absence of therapeutic management, it progresses to end-stage chronic renal failure. The aim of this study is to describe and analyse the observations of our patients with HP1. Patients and methods: This is a retrospective study carried out between 2014 and 2023 in the Nephrology-Dialysis Transplant Department of the Ibn Sina University Hospital in Rabat. The clinical, paraclinical and evolutionary elements were taken from the patients’ medical records. Results: We collected 11 cases, with a mean age of 27 ± 8.5 years and a M/F sex ratio of 1.7. The diagnosis of HP1 was made on the basis of genetic analysis in 8 patients, morphological and spectro-photometric analysis of the calculus in one patient, biopsy of the graft in one patient and crystalluria and a family history of PH1 in one patient. Two patients died, and 8 patients were on chronic haemdialysis with systemic damage. Only one patient maintained a stable GFR at 60 ml/min. Conclusion: Early diagnosis combined with conservative treatment is the only way to limit the rapid progression of this disease. This requires awareness and collaboration between nephrologists, urologists and biologists within a specialised team.

本研究将二氢杨梅素（Dihydromyricetin，DMY）作为核心来构建纳米粒子，并借助纳米粒子对DMY予以包封，旨在解决其水溶性差以及稳定性欠佳的难题，从而提高其利用率与生物活性。采用反溶剂沉淀法，以DMY为芯材，以玉米醇溶蛋白（Zein）为载体，构建Zein-阿拉伯胶（GA）纳米营养递送体系，以粒径、多分散指数（PDI）、zeta电位、包封率为指标优化了Zein/GA-DMY纳米粒子的制备条件。同时，采用傅里叶红外光谱（FT-IR）和X射线衍射（XRD）探讨了Zein、GA和DMY之间的相互作用，利用扫描电子显微镜（SEM）观察了该体系的微观形貌。结果表明，当Zein与阿拉伯胶的质量比为1:2，Zein与DMY质量比为10:1时，制备的纳米粒子粒径较小（191.04 nm），PDI为0.164，zeta电位为-17.70 mV，包封率为76.17%。氢键、静电和疏水相互作用是使该纳米粒子形成的主要驱动力，DMY以非晶体状态成功包埋在Zein/GA-DMY纳米粒子中，复合物呈球形，且分布均匀。GA的包覆使纳米粒子在一定条件下具备pH、加热、盐离子及储藏稳定性，扩展了其应用范围；体外抗氧化和模拟胃肠道消化实验表明经复合纳米粒子包封后DMY仍具备较强的抗氧化活性，同时呈现缓释特性。因此，本研究可为DMY在功能性食品领域的应用提供一定的理论基础。
