From single to combinatorial therapies in spinal cord injuries for structural and functional restoration

Neural Regeneration Research 2025年第3期20卷 660-670页

Spinal cord injury results in paralysis, sensory disturbances, sphincter dysfunction, and multiple systemic secondary conditions, most arising from autonomic dysregulation. All this produces profound negative psychosocial implications for affected people, their families, and their communities;the financial costs can be challenging for their families and health institutions. Treatments aimed at restoring the spinal cord after spinal cord injury, which have been tested in animal models or clinical trials, generally seek to counteract one or more of the secondary mechanisms of injury to limit the extent of the initial damage. Most published works on structural/functional restoration in acute and chronic spinal cord injury stages use a single type of treatment: a drug or trophic factor, transplant of a cell type, and implantation of a biomaterial. Despite the significant benefits reported in animal models, when translating these successful therapeutic strategies to humans, the result in clinical trials has been considered of little relevance because the improvement, when present, is usually insufficient. Until now, most studies designed to promote neuroprotection or regeneration at different stages after spinal cord injury have used single treatments. Considering the occurrence of various secondary mechanisms of injury in the acute and sub-acute phases of spinal cord injury, it is reasonable to speculate that more than one therapeutic agent could be required to promote structural and functional restoration of the damaged spinal cord. Treatments that combine several therapeutic agents, targeting different mechanisms of injury, which, when used as a single therapy, have shown some benefits, allow us to assume that they will have synergistic beneficial effects. Thus, this narrative review article aims to summarize current trends in the use of strategies that combine therapeutic agents administered simultaneously or sequentially, seeking structural and functional restoratio

Vascular tumors and malformations of the colon

引用

World Journal of Gastroenterology 2009年第41期15卷 5242-5243页

作者： israel Fernandez-Pineda Department of Pediatric Surgery Virgen del Rocio Children's Hospital

The term "hemangioma" refers to the common tumor of infancy that exhibits rapid postnatal growth and slow regression during childhood. It may cause confusion with venous malformations that are often incorrectly called "cavernous hemangioma". Venous malformations comprise abnormally formed channels that are lined by quiescent endothelium. Accurate diagnosis is required for selecting the appropriate treatment.

The Battle over Confucius and Classical Chinese Philosophy in European Early Enlightenment Thought （1670-1730）

引用

Frontiers of Philosophy in China 2013年第2期8卷 183-198页

作者： Jonathan israel School of Historical Studies Institute for Advanced Study Princeton NJ 08540 USA

A profound split is evident during the period 1670-1730 in the way European scholars and commentators attempted to understand and describe classical Chinese thought. For some, Confucianism acknowledged divine creation and divine governance of the world, immortality of the soul and other elements of Natural Theology. The Radical Enlightenment thinkers, however, and also some Christian scholars denied that Confucianism was based on Natural Theology or pervaded by belief in divine providence, characterizing it rather as monist, naturalist and Spinozist. The disagreement proved fundamental in several respects and proved divisive for the Church, as well as European thought more generally, producing a series of lively disputes that continued over several decades.

The promise of stem cell-based therapeutics in ophthalmology

The promising role of cellular therapies in the preservation and restoration of visual function has prompted intensive efforts to characterize embryonic, adult, and induced pluripotent stem cells for regenerative purposes. Three main approaches to the use of stem cells have been described： sustained drug delivery, immunomodulation, and differentiation into various ocular structures. Studies of the differentiation capacity of all three types of stem cells into epithelial, neural, glial and vascular phenotypes have reached proof-of-concept in culture, but the correction of vision is still in the early developmental stages, and the requirements for effective in vivo implementation are still unclear. We present an overview of some of the preclinical findings on stem-cell rescue and regeneration of the cornea and retina in acute injury and degenerative disorders.

World Journal of Emergency Medicine 2019年第2期10卷 81-87页

作者： israel Olatunji Gabriel Joel O.Aluko School of Post Basic Nursing Programmes (Anaesthesia) Ahmadu Bello University Teaching Hospital The Department of Nursing University of Ilorin

BACKGROUND: The aim of the study is to evaluate the theoretical knowledge and psychomotor skill acquisition of basic life support(BLS) by a group of secondary school students in Nigeria pre and post BLS training. METHODS: This was quasi-experimental study design with 210 participants. They were taught on adult BLS and all the participants practiced BLS on a Resusci-Anne manikin immediately after the training. Data were collected using American Heart Association(AHA) structured questionnaire and psychomotor skills checklist for BLS at baseline, and post BLS ***: The pre-training knowledge score was 1.9±1.4. This increased after the BLS training to 11.4±2.4, and the mean difference between the pre and post BLS training scores was 9.48571. Pre-training psychomotor skill score was 0.00±0.00, this increased to 8.9±1.9 after the training, and the mean difference was 8.90000. The knowledge and psychomotor skill difference between pre and post BLS training was signifi cant(P<0.000).CONCLUSION: Most Nigerian secondary school students were not knowledgeable about BLS. Therefore, there is need for the creation of more awareness among the students.
