Wolf Szmuness, epidemiologist and former roommate of a future Pope John Paul II, is named in an AIDS origin theory involving his hepatitis B vaccine trials
Wolf Szmuness (1919 – 1982) was a Polish-born epidemiologist who emigrated to and worked in the United States. He conducted research at the New York Blood Center and, from 1973, he was director of the Center’s epidemiology laboratory. He designed and conducted the trials for the first vaccine to prove effective against hepatitis B. European beginnings Szmuness was born in Warsaw, Poland on 12 March 1919.…

Adamalysin II, the protein world’s very own Eastern diamondback rattlesnake superstar
Adamalysin II, alias proteinase II, a 24 kDa zinc-endopeptidase isolated from the snake venom of the Eastern diamondback rattlesnake Crotalus adamanteus, is a prototype, of the proteolytic domain of snake venom metalloproteinases and of domains found in mammalian reproductive tract proteins.

Marx SO, Reiken S, Hisamatsu Y, Gaburjakova M, Gaburjakova J, Yang YM, Rosemblit N, Marks AR. Phosphorylation-dependent regulation of ryanodine receptors: a novel role for leucine/isoleucine zippers. J Cell Biol. 2001 May 14;153(4):699-708. doi: 10.1083/jcb.153.4.699. PMID: 11352932; PMCID: PMC2192391.
Abstract Ryanodine receptors (RyRs), intracellular calcium release channels required for cardiac and skeletal muscle contraction, are macromolecular complexes that include kinases and phosphatases. Phosphorylation/dephosphorylation plays a key role in regulating the function of many ion channels, including RyRs. However, the mechanism by which kinases and phosphatases are targeted to ion channels is not well understood.…

Oxytocin: The Molecular Maestro of Love and Labor
Buckle up, hormone enthusiasts! We’re about to take a wild ride into the world of oxytocin, the “love hormone” that’s been playing Cupid in our bodies since the dawn of mammalian evolution. This tiny peptide packs a punch that would make even Hercules jealous! Picture this: a molecule barely 1007 Da in size, strutting around…

Valine
Valine (symbol Val or V) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid. Valine is essential in humans, meaning the body cannot synthesize it; it…

Insall R. Dispatch. Dictyostelium chemotaxis: fascism through the back door? Curr Biol. 2003 Apr 29;13(9):R353-4. doi: 10.1016/s0960-9822(03)00274-4. PMID: 12725750.
Abstract Aggregating Dictyostelium cells secrete cyclic AMP to attract their neighbours by chemotaxis. It has now been shown that adenylyl cyclase is enriched in the rear of cells, and this localisation is required for normal aggregation. Dictyostelium discoideum cells undergo a major lifestyle change when they get hungry. They grow as unicellular amoebas, but when food starts to…

Eraso Y. Biotypology, endocrinology, and sterilization: the practice of eugenics in the treatment of Argentinian women during the 1930s. Bull Hist Med. 2007 Winter;81(4):793-822. doi: 10.1353/bhm.2007.0130. PMID: 18084107; PMCID: PMC2629848.
SUMMARYThis article looks at medical approaches to women’s fertility in Argentina in the 1930s and explores the ways in which eugenics encouraged the reproduction of the fit and attempted to avoid the reproduction of the unfit. The analysis concentrates on three main aspects: biotypology (the scientific classification of bodies), endocrine therapy, and sterilization. The article…

the hormone hustle
We’re about to embark on a time-traveling, mind-bending journey through the evolution of normalization, biopolitics, and the wild world of hormones. From Foucault’s philosophical bombshells to Nicola Pende’s hormone-fueled science experiments, this is a story that will leave you questioning everything you thought you knew about “normal.” Act I: The Birth of Biopower (18th Century) Picture…

Beccalossi C. Sexology, sexual development, and hormone treatments in Southern Europe and Latin America, c.1920-40. Hist Human Sci. 2023 Dec;36(5):94-121. doi: 10.1177/09526951231213028. Epub 2023 Dec 6. PMID: 38077463; PMCID: PMC10700059.
AbstractDisplacing the physiological model that had held sway in 19th-century medical thinking, early 20th-century medical scientists working on hormones promoted a new understanding of the body, psychological reactions, and the sexual instinct, arguing that each were fundamentally malleable. Hormones came to be understood as the chemical messengers that regulated an individual’s growth and sexual development,…

Beccalossi C. Italian sexology, Nicola Pende’s biotypology and hormone treatments in the 1920s. Hist Med Sante. 2017 Winter;12:73-97. doi: 10.4000/hms.1173. Epub 2018 May 28. PMID: 31501760; PMCID: PMC6733708.
AbstractThis article analyses a selection of Nicola Pende’s studies from the 1920s on ‘endocrinological abnormalities’ associated with impotence, a lack of virility in men, a lack of femininity in women, and homosexuality. By analysing endocrinological sexual theories and treatments, it aims to illustrate the ways in which hormone research pioneered an innovative approach to the…

BECCALOSSI C. Optimizing and normalizing the population through hormone therapies in Italian science, c.1926–1950. The British Journal for the History of Science. 2020;53(1):67-88. doi:10.1017/S0007087419000906
Abstract This essay explores how hormone treatments were used to optimize and normalize individuals under Italian Fascism. It does so by taking the activities of the Biotypological Orthogenetic Institute − an Italian eugenics and endocrinological centre founded by Nicola Pende in 1926 − as the prime example of a version of eugenics, biotypology, which was…

Quadrigen (DPT combined with the Salk polio vaccine) – random notes
In 1959, the Parke-Davis Quadrigen vaccine (DPT combined with the Salk polio vaccine) is licensed. The vaccine is alleged to be particularly reactive because of the effect of the preservative on the pertussis component. Several lawsuits ensue. The vaccine is withdrawn from the market in 1968 (Coulter and Fisher, 1985). Institute of Medicine (US) Committee…

The molecular mayhem of immunogens, haptens, carriers and adjuvants
First up, the immunogen: the molecular maestro of the immune system, orchestrating a symphony of B-cells and T-cells like a conductor with a grudge. These substances don’t just knock politely on the immune system’s door—they kick it down with the force of a battering ram. Immunogens are a subset of antigens (because “antibody-generating” wasn’t obvious enough)…
