Theodor Kocher (1841-1917) and his outstanding contributions to surgery

Theodor Kocher (1841-1917), an exceptional Swiss surgeon who described a technique for the safe removal of enlarged thyroid unraveled the true function of this endocrine gland but also made significant contributions to many other fields of surgery. Kocher was the first surgeon awarded the Nobel prize in Physiology and Medicine in 1909 for his work on the physiology, pathology, and surgery of the thyroid gland. He was professor and clinical director at Insel Hospital during 45 years. Kocher created the prominent Surgeon's School in Bern. He was the first president of the International Society of Surgery in 1903 and the founding president of the Swiss Society of Surgery in 1913.

Ivan Petrovich Pavlov and Santiago Ramón y Cajal, scientists and Nobel laureates of a new century / Iván Petrovich Pavlov y Santiago Ramón y Cajal, científicos y premios Nobel de un nuevo siglo

ABSTRACT Pavlov and Cajal were two influential scientists who developed their work in the late nineteenth and early twentieth centuries. Both won the Nobel Prize in Physiology or Medicine. The authors analyze the similarities between their life and work, delving into a single aspect: the Nobel prize obtained by both with only two years of difference: Pavlov in 1904 and Cajal in 1906, shared with Camilo Golgi. Both belonged to two declining empires when nationalism was still of some importance. The theories proposed by them more than 115 years ago are still valid in much of what they contributed in their respective disciplines.

RESUMEN Pavlov y Cajal fueron dos científicos influyentes que desarrollaron su trabajo a finales del siglo XIX y principios del XX. Ambos ganaron el premio Nobel de Fisiología o Medicina. Los autores analizan las similitudes entre su vida y obra, profundizando en un solo aspecto: el premio Nobel obtenido por ambos con tan solo dos años de diferencia: Pavlov en 1904 y Cajal en 1906, compartido con Camilo Golgi. Ambos pertenecían a dos imperios en decadencia, en un momento en que el nacionalismo todavía tenía cierta importancia. Las teorías propuestas por ellos, hace más de 115 años, siguen vigentes en lo fundamental de lo que aportaron en sus respectivas disciplinas.

D. Julius y A. Patapoutian. Premios Nobel de Medicina 2021, descubren nuevos canales iónicos que detectan temperatura y estímulos mecánicos / D. Julius y A. Patapoutian. 2021 Nobel Prize Awardees discover new ionic channels that detect temperature and mechanical stimuli

D. Julius was awarded the 2021 Medicine Nobel prize for the discovery of new cationic channels that detect temperatures either over 40 °C (TRPV1) or cold (TRPM8) ranging from 8-15 °C, followed by the latter identification of other channels that sense temperatures within other ranges. On the other hand, A. Patapoutian shared the 2021 Nobel prize for the independent and simultaneous co-discovery of the TRPM8 cationic channel. Furthermore, Patapoutian iden-tified piezo 1 and 2 channels previously referred to as the cell mechanosensors related to the sense of touch and proprioception. These experimental findings indicate that these novel cationic channels localized in nerve endings of the skin, mouth, lips, bronchial tree, the nephron, plus a variety of tissues transduce phy-sical stimuli into electrical activity that reach the brain sensory cortex to process these stimuli and elicit animal behavior.

La inhibición de los puntos de control inmunológico, una terapia en evolución: remembranza del Premio Nobel de Medicina 2018 / Immune checkpoint inhibitors: a breakthrough in cancer therapy

Professors James P. Allison and Tasuku Honjo were awarded with the 2018 Nobel Prize in Medicine for their contributions in cancer immunotherapy. The latter is a breakthrough in cancer therapy, aimed to overcome tumor-induced immunosuppression, leading to the reactivation of the immune system against cancer cells. Under physiological conditions, the CTLA-4 and PD-1 proteins expressed on T-cells and discovered by the awarded scientists, lead to immune tolerance. Cancer cells exploit these control points to enhance the inhibition of T-cells. The expression of PD ligands (PD-L1) in tumor cells and CTLA-4 ligands in antigen presenting cells, which bind the PD-1 receptor and CTLA-4 respectively, block anti-tumor immunity. This situation led to a biotechnological race focused on the development of effective antibodies able to "turn-on" the immune system cheated by the tumor. Anti-CTLA-4 and anti-PD-1 antibodies improve life-expectancy in cancer patients. In this review, we perform an historical overview of Professors Allison and Honjo contribution, as well as the immunological basis of this new and powerful therapeutic strategy, highlighting the clinical benefits of such intervention.

Grandes personajes de la medicina, grandes lecciones / Great personalities of medicine. Great lessons

Resumen El análisis de tres personajes correspondientes a espacios y tiempos diferentes muestra el estrecho vínculo entre la literatura y la historia de la medicina. Por un lado, don Quijote de la Mancha, quien refleja el pensamiento de los últimos años del Renacimiento y ha sido asimilado en el México contemporáneo. Por otro lado, los doctores Miguel Francisco Jiménez y Rita Levi Montalcini, quienes vivieron en los siglos XIX y XX, respectivamente. A pesar de los años que separan a los tres personaje, se advierten numerosos elementos en común que no pierden vigencia: el valor que se otorga a la salud, la ética, la tenacidad y la experiencia para obtener resultados exitosos, entre otros. Los tres personajes aluden a la medicina de su tiempo, los logros alcanzados y la promoción del humanismo, siempre inherente a la medicina.

Abstract The analysis of three characters corresponding to different spaces and times shows the close link between literature and the history of medicine. On one hand, Don Quixote of La Mancha, who reflects the thought of the last years of the Renaissance and that has been assimilated in contemporary Mexico. On the other hand, Doctors Miguel Francisco Jiménez and Rita Levi Montalcini who lived in the 19th and 20th centuries, respectively. Despite the years that separate these three personalities, many elements in common are observed that do not lose their validity: the value that is given to health, ethics, tenacity and experience to attain successful results. All three characters refer to the medicine of their time, their achievements and the promotion of humanism, always inherent to medicine.

A Reflection on the 2017 Nobel Prize for Physiology and Chinese Medicine / 中国结合医学杂志

Research on the molecular mechanisms controlling circadian rhythm in Western medicine is comparable to the study of a day-night rhythm in Chinese medicine (CM), as also focus on the same life phenomenon. By comparing the two, this paper elaborates on the differences between them in their respective issues of consciousness, ways of thinking, research methods and research results. Relatively speaking, Nobel Prize research has a stronger sense of the problems and concerns about the essence of "what", while CM focuses on "how a thing functions". The former mainly adopts experimental and mathematical methods, while the latter primarily depends on observation and understanding. The natural philosophy and natural science eventually lead to the results and the inevitable, quantitative and qualitative differences. Research on the life rhythm in CM should be proposed, scientific problems should be fully grasped, and research should be carried out with the aid of multidisciplinary new knowledge and new achievements through cross-disciplinary studies. On the basis of clinical epidemiological research and experimental research, a systematic review should be made of the human physiology of CM and the pathological rhythm model to explore the regulatory mechanism of time rhythm and create a new theory of time medicine.

Vision and the Nobel Prize / A visão e Prêmio Nobel

ABSTRACT The Nobel Prize is the world's foremost honor for scientific advances in medicine and other areas. Founded by Alfred Nobel, the prizes have been awarded annually since 1901. We reviewed the literature on persons who have won or competed for this prize in subjects related to vision and ophthalmology. The topics were divided into vision physiology, diagnostic and therapeutic methods, disease mechanism, and miscellaneous categories. Allvar Gullstrand is the only ophthalmologist to win a Nobel Prize; he is also the only one to receive it for work in ophthalmology. Other ophthalmologists that have been nominated were Hjalmar Schiötz (tonometer), Karl Koller (topical anesthesia), and Jules Gonin (retinal detachment). Other scientists have won the prize for eye-related research: Ragnar Granit, Haldan Hartline and George Wald (chemistry and physiology of vision), and David Hubel and Torsten Wiesel (processing in the visual system). Peter Medawar is the only person born in Brazil to have won the Nobel Prize.

RESUMO O Prêmio Nobel é a principal honraria do mundo para avanços científicos em medicina e outras áreas. Fundada por Alfred Nobel, os prêmios são concedidos anualmente desde 1901. Revisamos a literatura sobre pessoas que ganharam ou competiram por esse prêmio em assuntos relacionados à visão e oftalmologia. Os tópicos foram divididos em fisiologia da visão, métodos diagnósticos e terapêuticos, mecanismo de doenças e variados. Allvar Gullstrand não é o único oftalmologista a ganhar um Nobel, porém é o único a recebê-lo por contribuições na oftalmologia. Outros oftalmologistas foram nomeados: Hjalmar Schiötz (tonometro), Karl Koller (anestesia tópica) e Jules Gonin (descolamento da retina).

Peter Medawar é a única pessoa que nasceu no Brasil a ganhar o prêmio.

Discovery and Development of Artemisinin and Related Compounds / 中草药·英文版

Artemisinin is isolated from the plant Artemisia annua, sweet wormwood, an herb employed in traditional Chinese medicine. Prof. You-you Tu discovered artemisinin in the 1960s, so she was awarded the 2015 Nobel Prize in Physiology or Medicine. Artemisinin and its semi-synthetic derivatives are a group of drugs that possess the most rapid action of all current drugs against Plasmodium falciparum malaria. In this review, the author investigated history on discovery of artemisinin, ethnopharmacology of Artemisia plants, chemistry and pharmacological activities of the relative compounds, and introduced Tu and other Chinese and world scientists' contribution, development of artemisinin and the related compounds and registered and marketed artemisinin drugs in China, UK, and USA. The author also recalled the studies on the mechanism of action of artemisinins and artemisinin combination therapies and summed up the resistance issues. In Current Recommendations and the Global Plan for Insecticide Resistance Management in Malaria Vectors (GPIRM), that the WHO prevents the development and manages the spread of insecticide resistance is summarized in the technical basis for coordinated action against insecticide resistance: preserving the effectiveness of modern malaria vector control. Prof. Tu re-emphasized the artemisinin resistant on five principles to the WHO. She called on the world's scientists to pay attention to the study of drug resistance, and hopes scientists to contribute to break resistance of artemisinins.

On the centenary of the birth of Francis H. C. Crick – from physics to genetics and neuroscience / O centenário de nascimento de Francis H.C. Crick – da física para a genética e a neurociência

ABSTRACT The year 2016 marks the centenary of the birth of Francis Crick (1916–2004), who made outstanding contributions to genetics and neuroscience. In 1953, in a collaborative study, Francis Crick and James Watson discovered the DNA double helix, and in 1962 they and Maurice Wilkins were awarded the Noble Prize in Physiology or Medicine. Crick subsequently became very interested in neuroscience, particularly consciousness and its relationship to the claustrum, a small gray matter structure between the insula and putamen.

RESUMO O ano de 2016 é o centenário de nascimento de Francis Crick (1916–2004), físico, biólogo e neurocientista, cujas contribuições para a genética e a neurociência foram magníficas. Crick, em um estudo colaborativo com Watson, descobriu a estrutura molecular do DNA (dupla hélice) em 1953, e em 1962 ambos receberam o prêmio Nobel de Fisiologia ou Medicina, junto com Wilkins. Após Crick tornou-se muito interessado na área de neurociência, particularmente no estudo da consciência, e a sua relação com o claustrum, uma pequena estrutura de substância cinzenta localizada entre a ínsula e o putame.

Egas Moniz: twice a double life / Egas Moniz: uma dupla vida dupla

Egas Moniz is credited with the discovery in 1927 of radioarteriography, for which he was, on three occasions, nominated for the Nobel Prize, and in all three denied the award. In 1949 he was awarded the Nobel Prize for Medicine for having designed leucotomy, a brain surgery to treat some forms of severe metal disorders. He was also an successful politician and accomplished statesman.

Egas Moniz foi o inventor da radioarteriografia, em 1927. Devido a essa descoberta, seu nome foi, por três vezes, indicado para receber o Prêmio Nobel de Medicina e, nas três, não foi considerado merecedor do prêmio. Em 1949 finalmente ele recebeu o Nobel por ter concebido a leucotomia, um procedimento cirúrgico para “tratar certos transtornos mentais graves”. Ele foi, ainda, um homem político e um estadista de sucesso.

Santiago Ramón y Cajal, neurocientífico y pintor / Santiago Ramon y Cajal, neuroscientist and painter

La vida de este extraordinario científico y pintor ha sido motivo de estudio por generaciones, pues fascinó la manera de poder unir armoniosamente sus pasiones. Santiago Felipe Ramón y Cajal, más conocido como don Santiago Ramón y Cajal (el "don" por un título de importancia de la época e "y" como una forma de darle renombre a sus apellidos), o referido por muchos simplemente como Cajal (por la sonoridad del apellido y la costumbre en España de utilizar el apellido materno). Nació en la provincia de Cataluña, primer hijo de la unión de Justo Ramón Casasús y Antonia Cajal Puentes. Su padre, médico del pueblo, vio en él un sucesor de la profesión, razón por la cual desde muy pequeño le exigió académicamente y le reprochó su fascinación por el arte. Su infancia fue marcada por múltiples sucesos que lo llevarían a tener un encanto por la naturaleza y querer plasmarla en sus dibujos. La influencia de su padre fue exitosa, ya que se convirtió en un prestigioso médico. Ansioso de conocer otros lugares y su sed de aventurero lo llevaron a viajar a Cuba para dar apoyo médico a las tropas españolas. A su regreso se encontró con múltiples oportunidades que forjaron su carrera como científico y le dieron solidez como persona. Se casó a la edad de 27 años con Silveria Fañanás, el motor de su vida y la madre de sus seis hijos. Su incansable curiosidad y su espíritu de pintor le permitieron describir y dibujar las células nerviosas de manera detallada, incluyendo su estructura magnífica y las relaciones de estas, comparándolas de manera muy acertada con la naturaleza, referidas por él mismo como "El jardín de la neurología". Siempre fue un paisajista romántico, que se intrigó tanto de lo macro (con sus dibujos sobre la naturaleza y la anatomía), como de lo micro (la histología) (Figura 1).

The life of this extraordinary scientist and painter has been studied by multiple generations, fascinated by the way he harmoniously mixes his passions. Santiago Felipe Ramón y Cajal, better known as Don Santiago Ramón y Cajal (the "Don" as a title of the importance of the age and the "Y" as a way to give renown to their surnames) or referred by many simply as "Cajal" - by the sound of the surname). He was born in the province of Catalonia, first child of the union of Justo Ramón Casasús and Antonia Cajal. His father, a physician, saw in him a successor of the profession, which is why at very young age, he demanded of him the best academic performance and reproached him for his fascination with art. His childhood was marked by many events that would lead him to be charmed with nature and want to translate this into his drawings. The influence of his father was successful because he became a physician. Eager to know other places and with the thirst of an adventurer, he travelled to Cuba, but it was not the experience he had imagined. On his return he found many opportunities that forged his career as a scientist and gave him strength as a person. He married at the age of 27 years with Silveria Fañanás, who became the mother of his six children, and was the engine of his life. With his insatiable curiosity, his painter´s spirit and with some help, he described in detail the nerve cells and portrayed in his drawings the magnificent structure and relationships thereof, successfully comparing them with nature, referring to "The Garden of Neurology". He was always a romantic landscape painter, intrigued as much by the macro (with his drawings of nature and anatomy) as the micro (histology); the latter was his greatest passion. All his work bore many fruits, which still amaze us today. Through his hard work and his refusal to placate his inner painter, he managed to mix his passions to their maximum potential, leaving behind a priceless legacy.

La vitamina C y algo más: Un premio Nobel poco conocido en Chile / A biographical sketch of Albert Szent-Györgyi

Albert Szent-Györgyi was a Hungarian biochemist and physiologist. He identified the structure and function of vitamin C, naming it as ascorbic acid. His research on cellular respiration and oxidation provided the basis for Krebs’ citric acid cycle. He was awarded the Nobel Prize in 1937. With his collaborators, he discovered the biochemical basis of muscle contractility, isolating the basic proteins, giving them the name myosin and actin. Later on, he worked on the theory of carcinogenesis, linked to electron movements. He was one of the first researchers to describe the connection between free radicals and cancer. He lived a long, very complete life, defending always his opinion and freedom.
