Who invented the Braille system?
Louis Braille. Louis Braille ( / breɪl / ( listen); French: [lwi bʁaj]; 4 January 1809 – 6 January 1852) was a French educator and inventor of a system of reading and writing for use by the blind or visually impaired. His system remains virtually unchanged to this day, and is known worldwide simply as braille .
When was Braille invented?
Origins. In 1821 , Braille learned of a communication system devised by Charles Barbier. Barbier, aware of its potential for helping the blind to read and write, wrote to the school to introduce his method. Barbier's invention was a code of up to twelve dots in two columns, impressed into thick paper.
What did Braille learn?
Braille read the Haüy books repeatedly, and he was equally attentive to the oral instruction offered by the school. He proved to be a highly proficient student and, after he had exhausted the school's curriculum, he was immediately asked to remain as a teacher's aide. By 1833, he was elevated to a full professorship. For much of the rest of his life, Braille stayed at the Institute where he taught history, geometry, and algebra.
What did Braille do?
Later in life, his musical talents led him to play the organ for churches all over France. A devout Catholic, Braille held the position of organist in Paris at the Church of Saint-Nicolas-des-Champs from 1834 to 1839, and later at the Church of Saint-Vincent-de-Paul.
How did Braille work?
Braille worked tirelessly on his ideas, and his system was largely completed by 1824, when he was fifteen years old. From Barbier's night writing, he innovated by simplifying its form and maximizing its efficiency. He made uniform columns for each letter, and he reduced the twelve raised dots to six. He published his system in 1829, and by the second edition in 1837 he had discarded the dashes because they were too difficult to read. Crucially, Braille's smaller cells were capable of being recognized as letters with a single touch of a finger.
Why was Braille allowed to attend the first school for blind children?
Because of his combination of intelligence and diligence, Braille was permitted to attend one of the first schools for blind children in the world, the Royal Institute for Blind Youth, since renamed to the National Institute for Blind Youth in Paris.
How did Louis Braille survive?
Louis Braille survived the torment of the infection but by the age of five he was completely blind in both eyes. Due to his young age, Braille did not realize at first that he had lost his sight, and often asked why it was always dark. His parents made many efforts – quite uncommon for the era – to raise their youngest child in a normal fashion, and he prospered in their care. He learned to navigate the village and country paths with canes his father hewed for him, and he grew up seemingly at peace with his disability. Braille's bright and creative mind impressed the local teachers and priests, and he was accommodated with higher education.
Overview
Palbociclib, sold under the brand name Ibrance among others, is a medication developed by Pfizer for the treatment of HR-positive and HER2-negative breast cancer. It is a selective inhibitor of the cyclin-dependent kinases CDK4 and CDK6. Palbociclib was the first CDK4/6 inhibitor to be approved as a cancer therapy.
Mechanism of action
It is a selective inhibitor of the cyclin-dependent kinases CDK4 and CDK6.
In the G1 phase of the cell cycle, mammalian cells must pass a checkpoint, known as the restriction point "R", in order to complete the cell cycle and divide. CDK4 and CDK6 complex with cyclin D drive the phosphorylation of the retinoblastoma protein, Rb, which allows the cell to pass R and commit to division. Regulation of one or more proteins involved in this checkpoint is lost in many cancer…
Administration
Palbociclib is taken daily orally with food in a cycle of 21 days of active medication followed by 7 without. Currently palbociclib is prescribed as a combination therapy with either letrozole or fulvestrant. Patients should also not consume CYP3A inhibitors or inducers while taking palbociclib. FDA information also cautions against consuming grapefruit products while taking palbociclib.
Approvals and indications
The drug was reviewed and approved under the Food and Drug Administration’s (FDA) accelerated Priority Review and Breakthrough Therapy designation programs on February 3, 2015 as a treatment (in combination with letrozole) for patients with estrogen receptor positive (ER+) advanced breast cancer. This was an accelerated approval.
In March 2017, the FDA granted regular approval to palbociclib for hormone receptor (HR) positi…
Adverse effects
A majority of patients taking palbociclib experience neutropenia, a condition where a patient has an abnormally low number of neutrophils. This side effect impacts the immune system, and is thus likely responsible for the second most common side effect, infection. Leukopenia and anemia are also frequent among patients taking palbociclib. More than 10% of patients also experience side effects such as fatigue, nausea, diarrhea, respiratory infection, headache, thrombocytopenia, vomiti…
Mechanisms of resistance
FDA- and EMA-approval for palbociclib hinges upon the clinical trials’ results regarding progression-free survival (PFS). However, though data has proven promising (one study had p-values very close to the significance threshold which, with further clinical trials, may be able to demonstrate statistical significance), there is as of 2019 no significant improvement evident in overall survival (OS) when taking palbociclib. For example, in the PALOMA-2 trial, more than 70…
Clinical trials
The PALOMA-3 trial announced in April 2015 that the addition of palbociclib was superior to fulvestrant alone for progression-free survival.
In the phase II PALOMA-1 trial reported at the April 2014 annual meeting of the American Association for Cancer Research, the addition of palbociclib to letrozole was shown to significantly slow the progression of advanced cancer (median progression-free survival increase…
Drugs with a similar mechanism of action
Palbociclib has several direct competitors currently on the market or in clinical trials. In September 2017, abemaciclib, another selective CDK4/6 inhibitor owned and manufactured by Eli Lilly, was approved for HR-positive, HER2-negative advanced metastatic breast cancer both in combination with fulvestrant and as a monotherapy. In March 2017, the FDA also approved ribociclib, owned by Novartis, as a combination therapy with aromatase inhibitors for indications …
