Albert Brachet (1869-1930)
Albert Auguste Toussaint Brachet (1 January 1869 – 27 December 1930) was a Belgian physician and professor of anatomy and embryology at the University of Bruxelles. Brachet was a founder of the field of "causal embryology", the study of embryology and development using experiments. Brachet was born in Liège of French ancestry. He studied medicine in Liège where he took an interest in embryology under Edouard van Beneden. He worked for a while as histology preparator for Auguste Swaen. He received his doctor of medicine in 1894 followed by some studies at the University of Edinburgh under Sir William Turner and then in Germany under Ernst Gaupp and Gustav Jacob Born. He returned to Liège and became an assistant in anatomy in 1895. He studied cranial development in the amphibians and reptiles. In 1904, he became Chair of Anatomy and Embryology at Bruxelles where he worked until his death. His son Jean Brachet became a physiologist and biochemist Biochemists are scientists ...

Jean Brachet
Jean Louis Auguste Brachet (19 March 1909 – 10 August 1988) was a Belgian biochemist who made a key contribution in understanding the role of RNA. Life Brachet was born in Etterbeek near Brussels in Belgium, the son of Albert Brachet, embryologist. He was educated at L'Ecole Alsacienne in Paris then studied medicine at the Université Libre de Bruxelles graduating in 1934. He then worked at the University of Cambridge and at Princeton University and at several institutes of marine biological research. Brachet was appointed Professor of Animal Morphology and General Biology at the Université Libre de Bruxelles and Research Director of the International Laboratory for Genetics and Biophysics in Naples. In 1933 Brachet was able to show that DNA was found in chromosomes and that RNA was present in the cytoplasm of all cells.Sapp J., ''Jean Brachet, L'Hérédité Générale and the Origins of Molecular Embryology'', History and philosophy of the life sciences ( ...

Embryologists
Embryology (from Greek ἔμβρυον, ''embryon'', "the unborn, embryo"; and -λογία, ''-logia'') is the branch of animal biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos and fetuses. Additionally, embryology encompasses the study of congenital disorders that occur before birth, known as teratology. Early embryology was proposed by Marcello Malpighi, and known as preformationism, the theory that organisms develop from pre-existing miniature versions of themselves. Aristotle proposed the theory that is now accepted, epigenesis. Epigenesis is the idea that organisms develop from seed or egg in a sequence of steps. Modern embryology, developed from the work of Karl Ernst von Baer, though accurate observations had been made in Italy by anatomists such as Aldrovandi and Leonardo da Vinci in the Renaissance. Comparative embryology Preformationism and epigenesis As recently as the 18th century, the prevailing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930 Deaths
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Biochemist
Biochemists are scientists who are trained in biochemistry. They study chemical processes and chemical transformations in living organisms. Biochemists study DNA, proteins and cell parts. The word "biochemist" is a portmanteau of "biological chemist." Biochemists also research how certain chemical reactions happen in cells and tissues and observe and record the effects of products in food additives and medicines. Biochemist researchers focus on playing and constructing research experiments, mainly for developing new products, updating existing products and analyzing said products. It is also the responsibility of a biochemist to present their research findings and create grant proposals to obtain funds for future research. Biochemists study aspects of the immune system, the expressions of genes, isolating, analyzing, and synthesizing different products, mutations that lead to cancers, and manage laboratory teams and monitor laboratory work. Biochemists also have to have the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physiology
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, '' pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine.

Gustav Jacob Born (1851–1900) was a German histologist and author. He was the father of Max Born. Born was a native of Kempen (Kępno), Province of Posen. He received his education first at the gymnasium of Görlitz, Prussian Silesia, where his father practised as a physician and held the position of ''Kreisphysicus'' (district physician), and afterward at the universities of Breslau, Bonn, Straßburg, and Berlin, graduating as physician from Breslau in 1876. In the same year he was appointed assistant prosector and Privatdozent at the University of Breslau, and in 1877 prosector. In 1886, he was elected assistant professor, and in 1898 professor of histology and comparative anatomy, at the same university, receiving the Prussian Order of the Red Eagle of the fourth class in the latter year.

Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic and microscopic. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the br ...
