The color fresco Care of The Sick by Domenico di Bartolo, 1441–1442, depicting the Santa Maria della Scala hospital in Siena, Italy

Medicine is the science and practice of caring for patients, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of creativity and skill), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism. In recent centuries, since the advent of modern science, most medicine has become a combination of art and science (both basic and applied, under the umbrella of medical science). For example, while stitching technique for sutures is an art learned through practice, knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science.

Prescientific forms of medicine, now known as traditional medicine or folk medicine, remain commonly used in the absence of scientific medicine and are thus called alternative medicine. Alternative treatments outside of scientific medicine with ethical, safety and efficacy concerns are termed quackery. (Full article...)

  Taare Zameen Par (lit. 'Stars on Earth'), also known as Like Stars on Earth in English, is a 2007 Indian Hindi-language psychological drama film produced and directed by Aamir Khan. It stars Khan himself, with Darsheel Safary, Tanay Chheda, Vipin Sharma and Tisca Chopra. It explores the life and imagination of Ishaan (Safary), an artistically gifted 8-year-old boy whose poor academic performance leads his parents to send him to a boarding school, where a new art teacher Nikumbh (Khan) suspects that he is dyslexic and helps him to overcome his reading disorder.
  
  Creative director and writer Amole Gupte developed the idea with his wife Deepa Bhatia, who was the film's editor. Shankar–Ehsaan–Loy composed the score, and Prasoon Joshi wrote the lyrics for many of the songs. Principal photography took place in Mumbai, and in Panchgani's New Era High School, where some of the school's students participated in the filming. (Full article...)

  Buruli ulcer lesions. Top-left, an early ulcer. Top-right, a larger ulcer across the lower arm and wrist. Bottom, a large ulcer on the thigh.

  
  Buruli ulcer (/bəˈruːli/) is an infectious disease characterized by the development of painless open wounds. The disease is limited to certain areas of the world, most cases occurring in Sub-Saharan Africa and Australia. The first sign of infection is a small painless nodule or area of swelling, typically on the arms or legs. The nodule grows larger over days to weeks, eventually forming an open ulcer. Deep ulcers can cause scarring of muscles and tendons, resulting in permanent disability.
  
  Buruli ulcer is caused by skin infection with bacteria called Mycobacterium ulcerans. The mechanism by which M. ulcerans is transmitted from the environment to humans is not known, but may involve the bite of an aquatic insect or the infection of open wounds. Once in the skin, M. ulcerans grows and releases the toxin mycolactone, which blocks the normal function of cells, resulting in tissue death and immune suppression at the site of the ulcer.

  Thyrotoxic periodic paralysis occurs when the thyroid gland releases excessive amounts of thyroxine (thyroid hormone).

  
  Thyrotoxic periodic paralysis (TPP) is a rare condition featuring attacks of muscle weakness in the presence of hyperthyroidism (overactivity of the thyroid gland). Hypokalemia (a decreased potassium level in the blood) is usually present during attacks. The condition may be life-threatening if weakness of the breathing muscles leads to respiratory failure, or if the low potassium levels lead to abnormal heart rhythms. If untreated, it is typically recurrent in nature.
  
  The condition has been linked with genetic mutations in genes that code for certain ion channels that transport electrolytes (sodium and potassium) across cell membranes. The main ones are the L-type calcium channel α1-subunit and potassium inward rectifier 2.6; it is therefore classified as a channelopathy. The abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant.

  Cloth embroidered by a person diagnosed with schizophrenia

  
  Schizophrenia is a mental disorder characterized variously by hallucinations (typically, hearing voices), delusions, disorganized thinking and behavior, and flat or inappropriate affect. Symptoms develop gradually and typically begin during young adulthood and are never resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person. For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months (according to the DSM-5) or one month (according to the ICD-11). Many people with schizophrenia have other mental disorders, especially mood disorders, anxiety disorders, and obsessive–compulsive disorder.
  
  
  About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime. In 2017, there were an estimated 1.1 million new cases and in 2022 a total of 24 million cases globally. Males are more often affected and on average have an earlier onset than females. The causes of schizophrenia may include genetic and environmental factors. Genetic factors include a variety of common and rare genetic variants. Possible environmental factors include being raised in a city, childhood adversity, cannabis use during adolescence, infections, the age of a person's mother or father, and poor nutrition during pregnancy.

  Ray Fletcher Farquharson MBE (4 August 1897 – 1 June 1965) was a Canadian medical doctor, university professor, and medical researcher. Born in Claude, Ontario, he attended and taught at the University of Toronto for most of his life, and was trained and employed at Toronto General Hospital. With co-researcher Arthur Squires, Farquharson was responsible for the discovery of the Farquharson phenomenon, an important principle of endocrinology, which is that administering external hormones suppresses the natural production of that hormone.
  
  He served in the First and Second World Wars, earning appointment as a Member of the Order of the British Empire for his medical work during the latter. He chaired the Penicillin Committee of Canada and served as a medical consultant for the Royal Canadian Air Force. He was awarded the Queen's Coronation Medal in 1953 for his work for the Defence Review Board. Farquharson was also a charter member of the Royal College of Physicians and Surgeons of Canada.

  Microscopic image of a Lewy body (arrowhead) in a neuron of the substantia nigra; scale bar=20 microns (0.02 mm)

  
  Dementia with Lewy bodies (DLB) is a type of dementia characterized by changes in sleep, behavior, cognition, movement, and regulation of automatic bodily functions. Memory loss is not always an early symptom. The disease worsens over time and is usually diagnosed when cognitive impairment interferes with normal daily functioning. Together with Parkinson's disease dementia, DLB is one of the two Lewy body dementias. It is a common form of dementia, but the prevalence is not known accurately and many diagnoses are missed. The disease was first described on autopsy by Kenji Kosaka in 1976, and he named the condition several years later.
  
  REM sleep behavior disorder (RBD)—in which people lose the muscle paralysis (atonia) that normally occurs during REM sleep and act out their dreams—is a core feature. RBD may appear years or decades before other symptoms. Other core features are visual hallucinations, marked fluctuations in attention or alertness, and parkinsonism (slowness of movement, trouble walking, or rigidity). A presumptive diagnosis can be made if several disease features or biomarkers are present; the diagnostic workup may include blood tests, neuropsychological tests, imaging, and sleep studies. A definitive diagnosis usually requires an autopsy. (Full article...)

  Hirudo medicinalis sucking blood

  
  Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid; the coelom, the spacious body cavity found in other annelids, is reduced to small channels.
  
  The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, Hirudo medicinalis, are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from clotting. The jaws used to pierce the skin are replaced in other species by a proboscis which is pushed into the skin. A minority of leech species are predatory, mostly preying on small invertebrates.

  Holmes, c. 1880s

  
  Oliver Wendell Holmes Sr. (/hoʊmz/; August 29, 1809 – October 7, 1894) was an American physician, poet, and polymath based in Boston. Grouped among the fireside poets, he was acclaimed by his peers as one of the best writers of the day. His most famous prose works are the "Breakfast-Table" series, which began with The Autocrat of the Breakfast-Table (1858). He was also an important medical reformer. In addition to his work as an author and poet, Holmes also served as a physician, professor, lecturer, inventor, and, although he never practiced it, he received formal training in law.
  
  Born in Cambridge, Massachusetts, Holmes was educated at Phillips Academy and Harvard College. After graduating from Harvard in 1829, he briefly studied law before turning to the medical profession. He began writing poetry at an early age; one of his most famous works, "Old Ironsides", was published in 1830 and was influential in the eventual preservation of the USS Constitution. Following training at the prestigious medical schools of Paris, Holmes was granted his Doctor of Medicine degree from Harvard Medical School in 1836. He taught at Dartmouth Medical School before returning to teach at Harvard and, for a time, served as dean there. During his long professorship, he became an advocate for various medical reforms and notably posited the controversial idea that doctors were capable of carrying puerperal fever from patient to patient. Holmes retired from Harvard in 1882 and continued writing poetry, novels and essays until his death in 1894. (Full article...)

  Rolph, c. 1870

  
  John Rolph (4 March 1793 – 19 October 1870) was a Canadian physician, lawyer, and political figure. As a politician, he was considered the leader of the Reform faction in the 1820s and helped plan the Upper Canada Rebellion. As a doctor, he founded several medical schools and incorporated new teaching techniques and medical procedures into his lectures. However, his actions against rival medical schools decreased public confidence in the ability of medical professionals to regulate themselves.
  
  Rolph grew up in England and was educated in medicine and law. He immigrated to Upper Canada in 1813 and lived on his father's farm in Port Talbot, where he practiced law and medicine concurrently and opened a medical school called the Talbot Dispensary. In 1824, Rolph was elected to the Parliament of Upper Canada and returned to England to petition the Colonial Office to allow the naturalization of American citizens in Canada. He was elected as an alderman to Toronto's first city council, though he resigned after his council colleagues did not select him to be the city's mayor. (Full article...)

  Dark Archives: A Librarian's Investigation into the Science and History of Books Bound in Human Skin is a 2020 non-fiction book by the medical librarian and death-positive advocate Megan Rosenbloom. Dealing with anthropodermic bibliopegy, the binding of books in human skin, it expounds upon Rosenbloom's research on such books and their historical, ethical, and cultural implications.
  
  The book focuses on the relationship between anthropodermic bibliopegy and the history of medicine; most confirmed cases of such books were created or owned by medical professionals, in contrast to common stereotypes that they were associated with Nazi Germany, serial killers, or the French Revolution. Rosenbloom discusses how the practice reflects the changing attitudes towards consent, ownership, and disposal of human bodies, and how the history of anthropodermic books intertwines with the history of medical ethics as a field. She interviews librarians, archivists, collectors, and experts on the topic, and examines notable examples of such books and their origins. Though Rosenbloom supports the preservation and maintenance of anthropodermic books, Dark Archives also covers arguments to the contrary, such as those espoused by Princeton University Library senior librarian Paul Needham.

  Young people with polio receiving physiotherapy in the 1950s

  
  The social history of viruses describes the influence of viruses and viral infections on human history. Epidemics caused by viruses began when human behaviour changed during the Neolithic period, around 12,000 years ago, when humans developed more densely populated agricultural communities. This allowed viruses to spread rapidly and subsequently to become endemic. Viruses of plants and livestock also increased, and as humans became dependent on agriculture and farming, diseases such as potyviruses of potatoes and rinderpest of cattle had devastating consequences.
  
  Smallpox and measles viruses are among the oldest that infect humans. Having evolved from viruses that infected other animals, they first appeared in humans in Europe and North Africa thousands of years ago. The viruses were later carried to the New World by Europeans during the time of the Spanish Conquests, but the indigenous people had no natural resistance to the viruses and millions of them died during epidemics. Influenza pandemics have been recorded since 1580, and they have occurred with increasing frequency in subsequent centuries. The pandemic of 1918–19, in which 40–50 million died in less than a year, was one of the most devastating in history. (Full article...)

  A chest X-ray showing a tumor in the lung (marked by arrow)

  
  Lung cancer, also known as lung carcinoma, is a malignant tumor that begins in the lung. Lung cancer is caused by genetic damage to the DNA of cells in the airways, often caused by cigarette smoking or inhaling damaging chemicals. Damaged airway cells gain the ability to multiply unchecked, causing the growth of a tumor. Without treatment, tumors spread throughout the lung, damaging lung function. Eventually lung tumors metastasize, spreading to other parts of the body.
  
  Early lung cancer often has no symptoms and can only be detected by medical imaging. As the cancer progresses, most people experience nonspecific respiratory problems: coughing, shortness of breath, or chest pain. Other symptoms depend on the location and size of the tumor. Those suspected of having lung cancer typically undergo a series of imaging tests to determine the location and extent of any tumors. Definitive diagnosis of lung cancer requires a biopsy of the suspected tumor be examined by a pathologist under a microscope. In addition to recognizing cancerous cells, a pathologist can classify the tumor according to the type of cells it originates from. Around 15% of cases are small-cell lung cancer (SCLC), and the remaining 85% (the non-small-cell lung cancers or NSCLC) are adenocarcinomas, squamous-cell carcinomas, and large-cell carcinomas. After diagnosis, further imaging and biopsies are done to determine the cancer's stage based on how far it has spread. (Full article...)

  Amphetamine (contracted from alpha-methylphenethylamine) is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity; it is also used to treat binge eating disorder in the form of its inactive prodrug lisdexamfetamine. Amphetamine was discovered as a chemical in 1887 by Lazăr Edeleanu, and then as a drug in the late 1920s. It exists as two enantiomers: levoamphetamine and dextroamphetamine. Amphetamine properly refers to a specific chemical, the racemic free base, which is equal parts of the two enantiomers in their pure amine forms. The term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone. Historically, it has been used to treat nasal congestion and depression. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly controlled due to the significant health risks associated with recreational use.
  
  The first amphetamine pharmaceutical was Benzedrine, a brand which was used to treat a variety of conditions. Currently, pharmaceutical amphetamine is prescribed as racemic amphetamine, Adderall, dextroamphetamine, or the inactive prodrug lisdexamfetamine. Amphetamine increases monoamine and excitatory neurotransmission in the brain, with its most pronounced effects targeting the norepinephrine and dopamine neurotransmitter systems. (Full article...)

  Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug-resistant tuberculosis. It is used either by injection into a vein or by mouth.
  
  
  When given for short periods, linezolid is a relatively safe antibiotic. It can be used in people of all ages and in people with liver disease or poor kidney function. Common side effects with short-term use include headache, diarrhea, rash, and nausea. Serious side effects may include serotonin syndrome, bone marrow suppression, and high blood lactate levels, particularly when used for more than two weeks. If used for longer periods it may cause nerve damage, including optic nerve damage, which may be irreversible. (Full article...)

  Liver histology is altered in HRS while kidney histology is normal. The upper image is a trichrome stain (chicken wire appearance) cirrhosis of the liver, the most common cause of HRS. The lower image is a PAS stain of normal kidney histology.

  
  Hepatorenal syndrome (HRS) is a life-threatening medical condition that consists of rapid deterioration in kidney function in individuals with cirrhosis or fulminant liver failure. HRS is usually fatal unless a liver transplant is performed, although various treatments, such as dialysis, can prevent advancement of the condition.
  
  HRS can affect individuals with cirrhosis, severe alcoholic hepatitis, or liver failure, and usually occurs when liver function deteriorates rapidly because of a sudden insult such as an infection, bleeding in the gastrointestinal tract, or overuse of diuretic medications. HRS is a relatively common complication of cirrhosis, occurring in 18% of people within one year of their diagnosis, and in 39% within five years of their diagnosis. Deteriorating liver function is believed to cause changes in the circulation that supplies the intestines, altering blood flow and blood vessel tone in the kidneys. The kidney failure of HRS is a consequence of these changes in blood flow, rather than direct damage to the kidney. The diagnosis of hepatorenal syndrome is based on laboratory tests of individuals susceptible to the condition. Two forms of hepatorenal syndrome have been defined: Type 1 HRS entails a rapidly progressive decline in kidney function, while type 2 HRS is associated with ascites (fluid accumulation in the abdomen) that does not improve with standard diuretic medications.

  The New York Rescue Workers Detoxification Project was founded in New York City in 2003 with the stated purpose of treating rescue workers for toxins inhaled from the smoke of the September 11 attacks. It has two clinics: Downtown Medical on Fulton Street, two blocks from the site of the World Trade Center, and another at Williston Park, Long Island. The project's co-founder and top fundraiser is actor Tom Cruise. It uses the Purification Rundown, a detoxification program invented by L. Ron Hubbard as part of Scientology's Bridge to Total Freedom. This rundown has been criticized by many doctors as pseudoscientific and medically dangerous. It was reported in October 2007 that 838 people had completed the New York program.
  
  The project has been supported by some public officials, and received some public funding, but received criticism for its financial ties to the Church of Scientology, for exposing rescue workers to potential medical dangers, and for discouraging use of orthodox medicine. Sources in the Fire Department told a reporter that several participants had joined Scientology, even disconnecting from their families. (Full article...)

  Divers breathe a mixture of oxygen, helium and nitrogen for deep dives to avoid the effects of narcosis. A cylinder label shows the maximum operating depth and mixture (oxygen/helium).

  
  Narcosis while diving (also known as nitrogen narcosis, inert gas narcosis, raptures of the deep, Martini effect) is a reversible alteration in consciousness that occurs while diving at depth. It is caused by the anesthetic effect of certain gases at high partial pressure. The Greek word νάρκωσις (narkōsis), "the act of making numb", is derived from νάρκη (narkē), "numbness, torpor", a term used by Homer and Hippocrates. Narcosis produces a state similar to drunkenness (alcohol intoxication), or nitrous oxide inhalation. It can occur during shallow dives, but does not usually become noticeable at depths less than 30 metres (98 ft).
  
  Except for helium and probably neon, all gases that can be breathed have a narcotic effect, although widely varying in degree. The effect is consistently greater for gases with a higher lipid solubility, and although the mechanism of this phenomenon is still not fully clear, there is good evidence that the two properties are mechanistically related. As depth increases, the mental impairment may become hazardous. Divers can learn to cope with some of the effects of narcosis, but it is impossible to develop a tolerance. Narcosis can affect all ambient pressure divers, although susceptibility varies widely among individuals and from dive to dive. The main modes of underwater diving that deal with its prevention and management are scuba diving and surface-supplied diving at depths greater than 30 metres (98 ft). (Full article...)

  Woman during a migraine attack

  
  Migraine (UK: /ˈmiːɡreɪn/, US: /ˈmaɪ-/) is a genetically-influenced complex neurological disorder characterized by episodes of moderate-to-severe headache, most often unilateral and generally associated with nausea and light and sound sensitivity. Other characterizing symptoms may include vomiting, cognitive dysfunction, allodynia, and dizziness. Exacerbation or worsening of headache symptoms during physical activity is another distinguishing feature.
  
  Up to one-third of people with migraine experience aura, a premonitory period of sensory disturbance widely accepted to be caused by cortical spreading depression at the onset of a migraine attack. Although primarily considered to be a headache disorder, migraine is highly heterogenous in its clinical presentation and is better thought of as a spectrum disease rather than a distinct clinical entity. Disease burden can range from episodic discrete attacks to chronic disease. (Full article...)

  Egg allergy is an immune hypersensitivity to proteins found in chicken eggs, and possibly goose, duck, or turkey eggs. Symptoms can be either rapid or gradual in onset. The latter can take hours to days to appear. The former may include anaphylaxis, a potentially life-threatening condition which requires treatment with epinephrine. Other presentations may include atopic dermatitis or inflammation of the esophagus.
  
  In the United States, 90% of allergic responses to foods are caused by cow's milk, eggs, wheat, shellfish, peanuts, tree nuts, fish, soybeans, and sesame seeds. The declaration of the presence of trace amounts of allergens in foods is not mandatory in any country, with the exception of Brazil. (Full article...)

  Mayo, c. 1914

  
  Helen Mary Mayo OBE (1 October 1878 – 13 November 1967) was an Australian medical doctor and medical educator, born and raised in Adelaide. In 1896, she enrolled at the University of Adelaide, where she studied medicine. After graduating, Mayo spent two years working in infant health in England, Ireland and British India. She returned to Adelaide in 1906, starting a private practice and taking up positions at the Adelaide Children's Hospital and Adelaide Hospital (later the Royal Adelaide).
  
  In 1909, she co-founded the School for Mothers, where mothers could receive advice on infant health. This organisation, which became the Mothers' and Babies' Health Association in 1927, eventually established branches across South Australia and incorporated a training school for maternal nurses. In 1914, after unsuccessfully campaigning for the Children's Hospital to treat infants, Mayo co-founded the Mareeba Hospital for infants. (Full article...)

  Neuromuscular junction. Lambert–Eaton myasthenic syndrome is caused by autoantibodies to the presynaptic membrane. Myasthenia gravis is caused by autoantibodies to the postsynaptic acetylcholine receptors.

  1. Presynaptic terminal
  2. Sarcolemma
  3. Synaptic vesicle
  4. Nicotinic acetylcholine receptor
  5. Mitochondrion

  
  Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder characterized by muscle weakness of the limbs. It is also known as myasthenic syndrome, Eaton–Lambert syndrome, and when related to cancer, carcinomatous myopathy.
  
  
  Around 60% of those with LEMS have an underlying malignancy, most commonly small-cell lung cancer; it is therefore regarded as a paraneoplastic syndrome (a condition that arises as a result of cancer elsewhere in the body). It is the result of antibodies against presynaptic voltage-gated calcium channels, and likely other nerve terminal proteins, in the neuromuscular junction (the connection between nerves and the muscle that they supply). The diagnosis is usually confirmed with electromyography and blood tests; these also distinguish it from myasthenia gravis, a related autoimmune neuromuscular disease. (Full article...)

  A collaborative practice agreement (CPA) is a legal document in the United States that establishes a legal relationship between clinical pharmacists and collaborating physicians that allows for pharmacists to participate in collaborative drug therapy management (CDTM).
  
  CDTM is an expansion of the traditional pharmacist scope of practice, allowing for pharmacist-led management of drug related problems (DRPs) with an emphasis on a collaborative, interdisciplinary approach to pharmacy practice in the healthcare setting. The terms of a CPA are decided by the collaborating pharmacist and physician, though templates exist online. CPAs can be specific to a patient population of interest to the two parties, a specific clinical situation or disease state, and/or may outline an evidence-based protocol for managing the drug regimen of patients under the CPA.

  De Bourgoing in 1907

  
  Inès-Marie de Bourgoing, also Inès Fortoul, Inès Lyautey, (5 January 1862 – 9 February 1953) was a pioneering French nurse who served as president of the French Red Cross and established Red Cross nursing in Morocco. In recognition of her extensive social work, she became the first woman to be honoured with the rank of Grand Officer of the Legion of Honour. She was also decorated as a Grand Officer of the Order of Ouissam Alaouite in recognition of her work in Morocco.
  
  Born into the nobility, de Bourgoing was educated at court and married an artillery officer, Joseph Fortoul. Widowed, after raising her children, de Bourgoing chose the field of nursing as a means of helping alleviate poverty and participated in the first formal nursing classes offered in Paris. After she began working as a nurse, she went abroad with the Société de Secours aux Blessés Militaires, a forerunner of the French Red Cross, to work in North Africa. In 1907, she joined the SSBM and that same year, travelled to Morocco, where she established an infirmary in Casablanca. Fifteen months later, she assisted in disaster relief following an earthquake in Sicily. (Full article...)

The Briarcliff Manor Fire Department Ambulance Corps provides emergency medical transport with two ambulances. The fire department is headquartered at the Briarcliff Manor Village Hall, with its other station in Scarborough, on Scarborough Road.
  
  The Briarcliff Steamer Company No. 1 was founded in 1902 by Frederick C. Messinger. He became the first chief of the department, founded February 10, 1903. In 1906, the Briarcliff Fire Company was established. The village's municipal building and first permanent firehouse was built in 1914 in downtown Briarcliff Manor. Seven years later, in 1921, the Scarborough Fire Company was established. From 1930 to 1971, the Archville Fire Department was dissolved into Scarborough's fire company, which expanded its fire protection to Archville. In 1936, the Briarcliff Manor Hook and Ladder Company was formed. In 1963, the Briarcliff Manor Village Hall was constructed, again housing the fire and police departments. In 1974, a replacement firehouse was built for the Scarborough Engine Company, and in 2010, Scarborough's firehouse was again replaced, doubling its size. (Full article...)

  Behavioural genetics, also referred to as behaviour genetics, is a field of scientific research that uses genetic methods to investigate the nature and origins of individual differences in behaviour. While the name "behavioural genetics" connotes a focus on genetic influences, the field broadly investigates the extent to which genetic and environmental factors influence individual differences, and the development of research designs that can remove the confounding of genes and environment. Behavioural genetics was founded as a scientific discipline by Francis Galton in the late 19th century, only to be discredited through association with eugenics movements before and during World War II. In the latter half of the 20th century, the field saw renewed prominence with research on inheritance of behaviour and mental illness in humans (typically using twin and family studies), as well as research on genetically informative model organisms through selective breeding and crosses. In the late 20th and early 21st centuries, technological advances in molecular genetics made it possible to measure and modify the genome directly. This led to major advances in model organism research (e.g., knockout mice) and in human studies (e.g., genome-wide association studies), leading to new scientific discoveries.
  
  Findings from behavioural genetic research have broadly impacted modern understanding of the role of genetic and environmental influences on behaviour. These include evidence that nearly all researched behaviours are under a significant degree of genetic influence, and that influence tends to increase as individuals develop into adulthood. Further, most researched human behaviours are influenced by a very large number of genes and the individual effects of these genes are very small. Environmental influences also play a strong role, but they tend to make family members more different from one another, not more similar. (Full article...)

  Malpuech facial clefting syndrome, also called Malpuech syndrome or Gypsy type facial clefting syndrome, is a rare congenital syndrome. It is characterized by facial clefting (any type of cleft in the bones and tissues of the face, including a cleft lip and palate), a caudal appendage (a "human tail"), growth deficiency, intellectual and developmental disability, and abnormalities of the renal system (kidneys) and the male genitalia. Abnormalities of the heart, and other skeletal malformations may also be present. The syndrome was initially described by Georges Malpuech and associates in 1983. It is thought to be genetically related to Juberg-Hayward syndrome. Malpuech syndrome has also been considered as part of a spectrum of congenital genetic disorders associated with similar facial, urogenital and skeletal anomalies. Termed "3MC syndrome", this proposed spectrum includes Malpuech, Michels and Mingarelli-Carnevale (OSA) syndromes. Mutations in the COLLEC11 and MASP1 genes are believed to be a cause of these syndromes. The incidence of Malpuech syndrome is unknown. The pattern of inheritance is autosomal recessive, which means a defective (mutated) gene associated with the syndrome is located on an autosome, and the syndrome occurs when two copies of this defective gene are inherited.

  Official portrait, 2022

  
  Randal Howard Paul (born January 7, 1963) is an American politician serving as the junior United States senator from Kentucky since 2011. A member of the Republican Party, he has described himself as a constitutional conservative and a supporter of the Tea Party movement. His libertarian views have been compared to those of his father, three-time presidential candidate and 12-term U.S. representative from Texas, Ron Paul.
  
  Paul attended Baylor University and is a graduate of the Duke University School of Medicine. He was a practicing ophthalmologist in Bowling Green, Kentucky, from 1993 until his election to the U.S. Senate in 2010. He was re-elected to a second term in 2016 and won a third term in 2022.
