Microsomal prostaglandin E synthase-1 (mPGES-1)
Microsomal prostaglandin E synthase-1 (mPGES-1) or Prostaglandin E synthase is an enzyme that in humans is encoded by the PTGES gene. The protein encoded by this gene is a glutathione-dependent prostaglandin E synthase. The expression of this gene has been shown to be induced by proinflammatory cytokine interleukin 1 beta (IL1B). Its expression can also be induced by tumor suppressor protein TP53, and may be involved in…

Microfold cells (or M cells)
Microfold cells (or M cells) are found in the gut-associated lymphoid tissue (GALT) of the Peyer’s patches in the small intestine, and in the mucosa-associated lymphoid tissue (MALT) of other parts of the gastrointestinal tract. These cells are known to initiate mucosal immunity responses on the apical membrane of the M cells and allow for transport of microbes and particles across the epithelial cell layer from the gut lumen to the lamina…

Thunderstones in European Folklore
In Scandinavia thunderstones were frequently worshiped as family gods who kept off spells and witchcraft. Beer was poured over them as an offering, and they were sometimes anointed with butter. In Switzerland the owner of a thunderstone whirls it, on the end of a thong, three times around his head, and throws it at the door of his dwelling at the approach of…

Albanians believed the supreme powers of thunderstones were formed during lightning strikes
Albanians believed in the supreme powers of thunderstones (kokrra e rrufesë or guri i rejës), which were believed to be formed during lightning strikes and to fall from the sky. Thunderstones were preserved in family life as important cult objects. It was believed that bringing them inside the house would bring good fortune, prosperity, and progress to people, especially in livestock and agriculture,…

Prenatal exposure to paracetamol/acetaminophen and precursor aniline impairs masculinisation of male brain and behaviour
Paracetamol/acetaminophen (N-Acetyl-p-Aminophenol; APAP) is the preferred analgesic for pain relief and fever during pregnancy. It has therefore caused concern that several studies have reported that prenatal exposure to APAP results in developmental alterations in both the reproductive tract and the brain. Genitals and nervous system of male mammals are actively masculinised during foetal development and…

Intrauterine Exposure to Paracetamol and Aniline Impairs Female Reproductive Development by Reducing Follicle Reserves and Fertility
Studies report that fetal exposure to paracetamol/acetaminophen by maternal consumption can interfere with male reproductive development. Moreover, recent biomonitoring data report widespread presence of paracetamol in German and Danish populations, suggesting exposure via secondary (nonpharmaceutical) sources, such as metabolic conversion from the ubiquitous industrial compound aniline. In this study, we investigated the extent to which…

Aniline, through its conversion into antiandrogenic paracetamol (acetaminophen, tylenol), impairs male reproductive development
Industrial use of aniline is increasing worldwide with production estimated to surpass 5.6 million metric tons in 2016. Exposure to aniline occurs via air, diet, and water augmenting the risk of exposing a large number of individuals. Early observations suggest that aniline is metabolized to paracetamol/acetaminophen, likely explaining the omnipresence of low concentrations of paracetamol…

Vitellin is essential in the fertilization process, and embryonic development in egg-laying organisms
Vitellin is a protein found in the egg yolk. It is a phosphoprotein. Vitellin is a generic name for major of many yolk proteins. Vitellin has been known since the 1900s. The periodic acid-Schiff method and Sudan black B dye was used to help determine that Vitellin is a glycolipoprotein because it stained positive when tested. This protein was…
