Inexplicable spasms can now be explained with hormones

Researchers at Aarhus University have found a hormonal link to unexplained seizures in women, revealing a biological cause for the previously psychologically attributed condition. The study measured hormone levels in patients with psychogenic non-epileptic seizures (PNES) and found lower neuropeptide Y levels, associated with stress re...

RUDN chemists have discovered a new formation mechanism of anti-cancer substances

RUDN University scientists have discovered a new formation mechanism for anti-cancer substances, which can be used to synthesize organophosphorus compounds with specified properties. The researchers found that the reaction does not proceed according to the previously thought Michaelis-Arbuzov reaction mechanism, but rather another way.

Scratching the surface of mature monocytes...and coming up with CXCR7

A new study published in the Journal of Leukocyte Biology has identified a novel therapeutic target to reduce brain inflammation in diseases like multiple sclerosis and Parkinson's. Mature monocytes have been found to express CXCR7 receptor on their surface, which may be used to block inflammation and HIV infection in the brain.

University of Louisville lab helps discover new disease that causes kidney failure

Researchers at the University of Louisville discovered a new autoimmune disease that causes kidney failure, dubbed anti-brush border antibody (ABBA) disease. The disease was identified after analyzing biopsied kidney tissue from patients with acute kidney injury, and it affects the nephrons' brush borders by coating them with antibodies.

Digger wasps and their chemistry

Digger wasps have species-specific hydrocarbon profiles that vary according to their prey and brood-care strategy. Beetle-hunting digger wasps have more diversified profiles due to reduced need for prey preservation. The unique films are also used for defense against parasites.

What do piranhas and goldfish have in common?

A recent study published in Systematic Biology reveals that piranhas and goldfish are more closely related to catfishes than previously thought. The researchers used ultraconserved elements to reconstruct a Tree of Life for Ostariophysi fishes, revealing surprising relationships among the Characiformes order.

Chemists have created compounds that can treat glaucoma

Researchers from RUDN University designed new compounds that selectively inhibit human carbonic anhydrase, reducing intraocular pressure and potentially treating glaucoma. The study's findings suggest a promising approach for developing new antiglaucoma drugs by modifying the compound's molecular periphery.
