French Algeria
French Algeria ( until 1839, then afterwards; unofficially ; ), also known as Colonial Algeria, was the period of History of Algeria, Algerian history when the country was a colony and later an integral part of France. French rule lasted until the end of the Algerian War which resulted in Algeria's Independence Day (Algeria), gaining independence on 5 July 1962. The French conquest of Algeria began in 1830 with the Invasion of Algiers (1830), invasion of Algiers which toppled the Regency of Algiers, though Algeria was not fully conquered and Pacification of Algeria, pacified until 1903. It is estimated that by 1875, approximately 825,000 indigenous Algerians were killed. Various scholars describe the French conquest as genocide. Algeria was ruled as a French colony, colony from 1830 to 1848, and then as multiple Departments of France#Departments of Algeria (Départements d'Algérie), departments, an integral part of France, with the implementing of the French Constitution of 18 ...

Quinze-Vingts National Ophthalmology Hospital
The Quinze-Vingts National Ophthalmology Hospital (''Centre hospitalier national d’ophtalmologie des Quinze-Vingts'') is France's national ophthalmology hospital located in Paris, in the 12th arrondissement. The hospital gave its name to the ''Quinze-Vingts'' quarter. History The ''Hospice des Quinze-Vingts'', a hospital for the blind, was founded in 1260 by Louis IX, king of France, also known as "Saint Louis". It was constructed on a piece of land called "Champ-Pourri",J-A Delaure et Gabriel Roux, ''Histoire de Paris'', 1853, p. 132 an area lying a short distance west of the Louvre fortress, outside the fortified wall built by Philippe Augustus from 1190 to 1209. It became included within the city after the erection of the new fortified wall of Charles V built between 1356 and 1383. Within the new neighborhood thus formed west of the Louvre, it was located on ''rue Saint-Honoré'' at the corner of the ''rue Saint-Nicaise'', (in the area between the Palais-Royal and Plac ...

Institut Langevin
ESPCI Paris (officially the École supérieure de physique et de chimie industrielles de la ville de Paris, , ''The City of Paris Industrial Physics and Chemistry Higher Educational Institution'') is a grande école founded in 1882 by the city of Paris, France. It educates undergraduate and graduate students in physics, chemistry and biology and conducts high-level research in those fields. It is ranked as the first French ''École d'Ingénieurs'' in the 2017 Shanghai Ranking. ESPCI Paris is a constituent college of Université PSL and a founding member of the ParisTech (Paris Institute of Technology) alliance. Two thirds of the students enter the school following a competitive examination (concours X-ESPCI- ENS) following at least two years of Classes Préparatoires. The other students are recruited by submitting applications. The school itself is also known as Physique-Chimie or simply PC. ESPCI Paris nurtures relationships with many industrial partners such as Schlumberger, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visual Prosthesis
A visual prosthesis, often referred to as a bionic eye, is a visual device intended to restore functional vision in those with partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s. The idea of using electrical current (e.g., electrically stimulating the retina or the visual cortex) to provide sight dates back to the 18th century, discussed by Benjamin Franklin, Tiberius Cavallo, and Charles LeRoy. Biological considerations The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight. For retinal prostheses, which are the most prevalent visual prosthetic under development (due to ease of access to the retina among other considerations), patients with vision loss due to degeneration of photoreceptors (retinitis pigmentosa, choroideremia, geographic atrophy macular degeneration) are the best c ...

Pharmacology
Pharmacology is the science of drugs and medications, including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, functions, sources, synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. The two main areas of pharmacology are pharmacodynamics and pharmacokinetics. Pharmacodynamics studies the effects of a drug on biological systems, and pharmacokinetics studies the effects of biological systems on a drug. In broad terms, pharmacod ...

Gene Therapy
Gene therapy is Health technology, medical technology that aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells. The first attempt at modifying human DNA was performed in 1980, by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. Between 1989 and December 2018, over 2,900 clinical trials were conducted, with more than half of them in Phases of clinical research, phase I. In 2003, Gendicine became the first gene therapy to receive regulatory approval. Since that time, further gene therapy drugs were approved, such as alipogene tiparvovec (2012), Strimvelis (2016), tisagenlecleucel (2017), voretigene neparvovec ...

Stem Cell
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can change into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50 to 150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. '' In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. However, whe ...

Neuroprotection
Neuroprotection refers to the relative preservation of neuronal structure and/or function. In the case of an ongoing insult (a neurodegenerative insult) the relative preservation of neuronal integrity implies a reduction in the rate of neuronal loss over time, which can be expressed as a differential equation. Mechanisms in neurodegeneration, and associated treatments It is a widely explored treatment option for many central nervous system disorders including neurodegenerative diseases, stroke, traumatic brain injury, spinal cord injury, and acute management of neurotoxin consumption (i.e. methamphetamine Methamphetamine (contracted from ) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational drug use, recreational or Performance-enhancing substance, performance-enhancing drug and less commonly as a secon ... overdoses).
