Insulin is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the insulin (INS) gene. It is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both. Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in the blood. Circulating insulin also affects the synthesis of proteins in a wide variety of tissues. It is therefore an anabolic hormone, promoting the conversion of small molecules in the blood into large molecules inside the cells. Low insulin levels in the blood have the opposite effect by promoting widespread catabolism, especially of reserve body fat.
Glucagon is a peptide hormone, produced by alpha cells of the pancreas. It raises the concentration of glucose and fatty acids in the bloodstream and is considered to be the main catabolic hormone of the body. It is also used as a medication to treat a number of health conditions. Its effect is opposite to that of insulin, which lowers extracellular glucose. It is produced from proglucagon, encoded by the GCG gene.
Bernardo Alberto Houssay was an Argentine physiologist. Houssay was a co-recipient of the 1947 Nobel Prize for Physiology or Medicine for discovering the role played by pituitary hormones in regulating the amount of glucose in animals, sharing the prize with Carl Ferdinand Cori and Gerty Cori. He is the first Latin American Nobel laureate in the sciences.
Chernivtsi is a city in southwestern Ukraine on the upper course of the Prut River. Formerly the capital of the historic region of Bukovina, which is now divided between Romania and Ukraine, Chernivtsi serves as the administrative center for the Chernivtsi Raion, the Chernivtsi urban hromada, and the oblast itself. In 2022, the Chernivtsi population, by estimate, is 264,298, and the latest census in 2001 was 240,600.
Alpha cells (α-cells) are endocrine cells that are found in the Islets of Langerhans in the pancreas. Alpha cells secrete the peptide hormone glucagon in order to increase glucose levels in the blood stream.
Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a hormone similar in molecular structure to insulin which plays an important role in childhood growth, and has anabolic effects in adults.
Hyperandrogenism is a medical condition characterized by high levels of androgens. It is more common in women than men. Symptoms of hyperandrogenism may include acne, seborrhea, hair loss on the scalp, increased body or facial hair, and infrequent or absent menstruation. Complications may include high blood cholesterol and diabetes. It occurs in approximately 5% of women of reproductive age.
Zvi Laron is an Israeli paediatric endocrinologist. Born in Cernăuţi, Romania, Laron is a professor emeritus at Tel Aviv University. In 1966, he described the type of dwarfism later called Laron syndrome. His research opened the way to the treatment of many cases of growth hormone disorders. He was the first to introduce the multidisciplinary treatment for juvenile diabetes.
Testosterone enanthate is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men. It is also used in hormone therapy for transgender men. It is given by injection into muscle or subcutaneously usually once every one to four weeks.
Pattern hair loss is a hair loss condition that primarily affects the top and front of the scalp. In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the crown (vertex) of the scalp, or a combination of both. Female-pattern hair loss (FPHL) typically presents as a diffuse thinning of the hair across the entire scalp.
Seale Harris was an American physician and researcher born in Cedartown, Georgia. He was nicknamed "the Benjamin Franklin of Medicine" by contemporaries for his leadership and writing on a wide range of medical and political topics. Dr. Harris' most celebrated accomplishments were his 1924 hypothesis of hyperinsulinism as a cause of spontaneous hypoglycemia.
The ACTH test is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone or another corticotropic agent such as tetracosactide or alsactide (Synchrodyn). ACTH is a hormone produced in the anterior pituitary gland that stimulates the adrenal glands to release cortisol, dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), and aldosterone.
As a medication, insulin is any pharmaceutical preparation of the protein hormone insulin that is used to treat high blood glucose. Such conditions include type 1 diabetes, type 2 diabetes, gestational diabetes, and complications of diabetes such as diabetic ketoacidosis and hyperosmolar hyperglycemic states. Insulin is also used along with glucose to treat hyperkalemia. Typically it is given by injection under the skin, but some forms may also be used by injection into a vein or muscle. There are various types of insulin, suitable for various time spans. The types are often all called insulin in the broad sense, although in a more precise sense, insulin is identical to the naturally occurring molecule whereas insulin analogues have slightly different molecules that allow for modified time of action. It is on the World Health Organization's List of Essential Medicines. In 2021, it was the 179th most commonly prescribed medication in the United States, with more than 2 million prescriptions.
Do-it-yourself biology is a biotechnological social movement in which individuals, communities, and small organizations study biology and life science using the same methods as traditional research institutions. DIY biology is primarily undertaken by individuals with limited research training from academia or corporations, who then mentor and oversee other DIY biologists with little or no formal training. This may be done as a hobby, as a not-for-profit endeavor for community learning and open-science innovation, or for profit, to start a business.
Andrew Hessel is a pioneer in synthetic biology, a futurist, microbiologist and geneticist, and inventor and entrepreneur. He is a proponent of open source biology and advocates that cells are living computers and DNA is a programming language. He has been advocating for writing DNA since shortly after the original Human Genome Project, and co-founded the Genome Project-write. Hessel is an expert in biological technologies and biosecurity, helping industry, academics, and authorities better understand the rapid changes in life science.
Antonio Vidal-Puig is a Spanish medical doctor and scientist who works as a Professor of Molecular Nutrition and Metabolism at the University of Cambridge (UK), best known for advancing the concept that pharmacological targeting of brown fat may serve to treat overweight and obesity in affected individuals, as well as for introducing the concept of adipose tissue "expandability" as an important factor in the pathogenesis of insulin resistance in the context of positive energy balance. His published work focuses on areas such as adipose tissue metabolism and lipotoxicity, regulation of insulin secretion, and the pathophysiology of metabolic syndrome, obesity, and type 2 diabetes.
The demolition of monuments to dedicated to Russian poet and playwright Alexander Pushkin in Ukraine started during the Russo-Ukrainian War. Since the Russian invasion of Ukraine in 2022, it has become a widespread phenomenon and dubbed by Ukrainians Pushkinopad, a pun literally translated as "Pushkinfall", akin to the "Leninfall" during the decommunization process. This wave of dismantling is part of the process of derussification in Ukraine.
