Marcello Malpighi.

Marcello Malpighi (10 March 1628 – 29 November 1694) was an Italian doctor, who gave his name to several physiological features, like the Malpighian tubule system.

Early years[link]

Malpighi was born on March 10, 1628 at Crevalcore near Bologna, Italy. The son of well-to-do parents, Malpighi was educated in his native city, entering the University of Bologna at the age of 17.^[1] In a posthumous work delivered and dedicated to the Royal Society in London in 1697, Malpighi says he completed his grammatical studies in 1645, at which point he began to apply himself to the study of Peripatetic Philosophy. He completed these studies about 1649, where at the persuasion of his mother Frances Natalis he began to study physics. When his parents and grandmother became ill, he returned to his family home near Bologna to care for them.

Career[link]

In 1653, his father, mother, and grandmother being dead, Malpighi left his family villa and returned to the University of Bologna to study Anatomy. In 1656 he was made a reader at Bologna, and then a professor of physics at Pisa, where he began to abandon the disputative method of learning and apply himself to a more experimental method of research. Based on this research, he wrote some Dialogues against the Peripatetics and Galenists (those who followed the precepts of Galen), which were destroyed when his house burned down. Weary of philosophical disputation, in 1660, Malpighi returned to Bologna and dedicated himself to the study of anatomy. He subsequently discovered a new structure of the lungs which led him to several disputes with the learned medical men of the times. In 1662, he was made a professor of Physic at the Academy of Messina.^[2]

Retiring from university life to his villa in the country near Bologna in 1663, he worked as a physician while continuing to conduct experiments on the plants and insects he found on his estate. There he made discoveries of the structure of plants which he published in his Observations. At the end of the year 1666, Malpighi was invited by the Italian Senate to return to the public academy at Messina, which he did in 1667. Although he accepted temporary chairs at the universities of Pisa and Messina, throughout his life he continuously returned to Bologna to practice medicine, a city that repaid him by erecting a monument in his memory after his death.^[3]

In 1668, Malpighi received a letter from Mr. Oldenburg of the Royal Society in London, inviting him to correspond. Malpighi wrote his history of the silkworm in 1668, and sent the manuscript to Mr. Oldenburg. As a result, Malpighi was made a member of the Royal Society in 1669. In 1671, Malpighi’s Anatomy of Plants was published in London by the Royal Society, and he simultaneously wrote to Mr. Oldenburg, telling him of his recent discoveries regarding the lungs, fibers of the spleen and testicles, and several other discoveries involving the brain and sensory organs. He also shared more information regarding his research on plants. At that time, he related his disputes with some younger physicians who were strenuous supporters of the Galenic principles and opposed to all new discoveries. Following many other discoveries and publications, in 1691, Malpighi was uprooted from his beloved home in Bologna and summoned to Rome by Pope Innocent XII as papal physician, which position he held until his death three years later. He died of apoplexy in 1694.^[4]

Marcello Malpighi is buried in the church of the Santi Gregorio e Siro, in Bologna, where nowadays can be seen a marble monument to the scientist with an inscription in Latin remembering - among other things - his "SUMMUM INGENIUM / INTEGERRIMAM VITAM / FORTEM STRENUAMQUE MENTEM / AUDACEM SALUTARIS ARTIS AMOREM" (great genius, honest life, strong and tough mind, daring love for the medical art).

Research[link]

Around the age of 38, and with a remarkable academic career behind him, Malpighi decided to dedicate his free time to anatomical studies.^[5] Although he conducted some of his studies using vivisection and others through the dissection of corpses, his most illustrative efforts appear to have been based on the use of the microscope. Because of this work, many microscopic anatomical structures are named after Malpighi, including a skin layer (Malpighi layer) and two different Malpighian corpuscles in the kidneys and the spleen, as well as the Malpighian tubules in the excretory system of insects.

See Timeline of microscope technology for more information.

Although a Dutch spectacle maker created the compound lens and inserted it in a microscope around the turn of the seventeenth century, and Galileo had applied the principle of the compound lens to the making of his microscope patented in 1609, its possibilities as a microscope had remained unexploited for half a century, until Robert Hooke improved the instrument. Following this, Marcello Malpighi, Hooke and two other early investigators associated with the Royal Society, Nehemiah Grew and Antoine van Leeuwenhoek were fortunate to have a virtually untried tool in their hands as they began their investigations.^[6]

Working on frogs and extrapolating to humans, Malpighi demonstrated the structure of the lungs, previously thought to be a homogeneous mass of flesh, and he offered an explanation for how air and blood mixed in the lungs.^[7] Malpighi also used the microscope for his studies of the skin, kidneys, and liver. For example, after he dissected a black male, Malpighi made some groundbreaking headway into the discovery of the origin of black skin. He found that the black pigment was associated with a layer of mucus just beneath the skin.

He was the first to see capillaries in animals, and he discovered the link between arteries and veins that had eluded William Harvey. He may have been the first person to see red blood cells under a microscope. His treatise 'De polypo cordis' (1666) was important for understanding blood composition, as well as how blood clots. In it, Malpighi described how the form of a blood clot differed in the right vs. the left sides of the heart.

The use of the microscope enabled Malpighi to discover that insects (particularly, the silk worm) do not use lungs to breathe, but small holes in their skin called tracheae. Malpighi also studied the anatomy of the brain and concluded that this organ is a gland. In terms of modern endocrinology this deduction is correct because the hypothalamus of the brain has long been recognized for its hormone-secreting capacity.

Because Malpighi had a wide knowledge of both plants and animals, he made contributions to the scientific study of both. The Royal Society in London published two volumes of his botanical and zoological works in 1675 and 1679. Another edition followed in 1687, and a supplementary volume in 1697.^[8] In his autobiography, Malpighi speaks of his Anatome Plantarum, decorated with the engravings of Robert White (1645–1703) as "the most elegant format in the whole literate world."^[9]

His study of plants led him to conclude that plants had tubules similar to those he saw in insects like the silk worm (using his microscope, he probably saw the stomata, through which plants exchange carbon dioxide with oxygen). Malpighi observed that when a ring-like portion of bark was removed on a trunk a swelling occurred in the tissues above the ring, and he correctly interpreted this as growth stimulated by food coming down from the leaves, and being blocked above the ring.

A talented sketch artist, Malpighi seems to have been the first author to have made detailed drawings of individual organs of flowers. In his Anatome plantarum, there is a longitudinal section of a flower of Nigella (his Melanthi, literally honey-flower) with details of the nectariferous organs. He adds that it is strange that nature has produced on the leaves of the flower shell-like organs in which honey is produced.^[10]

Malpighi had success in tracing the ontogeny of plant organs, and the serial development of the shoot owing to his instinct shaped in the sphere of animal embryology. He specialized in seedling development, and in 1679 he published a volume containing a series of exquisitely drawn and engraved images of the stages of development of Legumeninosae (beans) and Cucurbitae (squash, melons). Later he published material depicting the development of the date palm. The great Swedish botanist Linnaeus named the genus Malpighia in honor of Malpighi’s work with plants; Malpighia is the type genus for the Malpighiaceae, a family of tropical and subtropical flowering plants.

Because Malpighi was concerned with teratology (the scientific study of the visible conditions caused by the interruption or alteration of normal development) he expressed grave misgivings about the view of his contemporaries that the galls of trees and herbs gave birth to insects. He conjectured that the creatures in question arose from eggs previously laid in the plant tissue.^[11]

Malpighi’s investigations of the life cycle of plants and animals led him into the topic of reproduction. He created detailed drawings of his studies of chick embryo development, seed development in plants (such as the lemon tree) and the transformation of caterpillars into insects. His discoveries helped to illuminate philosophical arguments surrounding the topics of emboîtment, pre-existence, preformation, epigenesis, and metamorphosis.^[12]

Years in Rome[link]

In 1691 Pope Innocent XII invited him to Rome as Papal physician. He taught medicine in the Papal Medical School and wrote a long treatise about his studies which he donated to the Royal Society of London.

Marcello Malpighi died of apoplexy (an old-fashioned term for a stroke or stroke-like symptoms) in Rome on September 30, 1694 at the age of 66. In accordance with his wishes, an autopsy was performed. The Royal Society published his studies in 1696.

Carolina Gómez Correa (born February 26, 1974 ^[1] in Cali, Colombia) is a Colombian actress, presenter and model, who held the title of Miss Colombia Universe 1993 - 1994 and Miss Universe First Runner-up 1994 .

Biography[link]

In the early years of her life, Carolina went to live to the United States of America and returned to Bogotá when she was eighteen years old. Later, she represented Bogota as a delegate to the Miss Colombia Contest, Concurso Nacional de Belleza, where she was named as the new titleholder of the Señorita Colombia title in 1993. After that, she traveled to Manila, Philippines to represent her country in the Miss Universe 1994 Pageant where she was First Runner-up; Carolina Gomez was the third Colombian to win First Runner-up in a Miss Universe competition, after Paola Turbay in 1992 and Paula Andrea Betancourt Arroyave in 1993.

After this stage of her life, Carolina went into modeling, achieving success on runways in Italy and Miami. She was the host of "Stars", a television show where many artists and celebs were interviewed and then, she was the successor of Jaime Garzón in the presentation of "Locos Videos". She was also a TV Producer, as co-chair of Vista Productions Inc. In 2004, she made her acting debut in a soap opera, "El Auténtico Rodrigo Leal", telecasted by Caracol Channel (in Colombia), where she had the role of the host of a TV Reality Program with the Argentinian actor Martín Karpan. Her acting in this role received excellent reviews, which led to her role as protagonist in "La Viuda de la Mafía", another soap opera, on the air between 2006 and 2006 and telecast by the RCN Channel (another Colombian Channel). Between 2007 and 2010 she has workes in different TV series such as Mujeres Asesinas, Sin Retorno, Tiempo Final and Karabudjan. The latter a 6 hour miniseries for Antena 3 in Spain. Actually she is playing Alicia Duran in A Corazon Abierto, the Colombian adaptation of Grey's Anatomy. This series recently became the highest rating show in the history of Colombian television, surpassing Fernando Gaitan's worldwide success: Ugly Betty.

She also starred in several films, including "Bluff", with Catalina Aristizabal, Victor Mallarino and Luis Eduardo Arango, amongst others. The film, which premiered in March 2007, had very good reviews and very high box office revenues in Colombia. In 2010, she traveled to Los Angeles to co-star the film The Chosen One along with comedian Rob Schneider (who also wrote and directed the movie). Her successful career led her to work in Federals, a Brazilian action film with Michael Madsen, Saluda al Diablo de mi parte along with Edgar Ramirez, and most recently: El Paseo, a family road trip comedy shot in the beautiful Colombian countryside. Carolina is the fourth Colombian actress to penetrate the American cinema market, along with Sofía Vergara, Paola Turbay and Catalina Sandino.

Carolina Gómez was married and separated twice, with Nicolas Hoyos, her teenage boyfriend and father of her son, Tomas.
