Article Abstract
Feeding of (2,3,4,5,6-(13) C5 )mevalonolactone to the fungus Hypomyces odoratus resulted in a completely labeled sesquiterpene ether. The connectivity of the carbon atoms was easily deduced from a (13) C,(13) C COSY spectrum, revealing a structure that was different from the previously reported structure of hypodoratoxide, even though the reported (13) C NMR data matched. A structural revision of hypodoratoxide is thus presented. Its absolute configuration was tentatively assigned from its co-metabolite cis-dihydroagarofuran. Its biosynthesis was investigated by feeding of (3-(13) C)- and (4,6-(13) C2 )mevalonolactone, which gave insights into the complex rearrangement of the carbon skeleton during terpene cyclization by analysis of the (13) C,(13) C couplings.

Background: Laboratory animal veterinarians play a crucial role as a bridge between the ethical use of laboratory animals and the advancement of scientific and medical knowledge in biomedical research. They alleviate pain and reduce distress through veterinary care of laboratory animals. Additionally, they enhance animal welfare by creating environments that mimic natural habitats through environmental enrichment and social associations.

Objectives/background: Prior studies have claimed that people engage in compulsive buying in an attempt to deal with stress. Nonetheless, not every stressed person engages in compulsive buying. It is therefore important to investigate the cognitive mechanisms underlying such behavior.

Since the erection of the genus, with Flapocephalus trygonis Deshmukh, 1979, as the type species, and the description of a second species, Flapocephalus saurashtri Shinde and Deshmukh, 1979, both from Pastinachus sephen (Fabricius) from India, reports of this genus have been restricted mainly to brief mentions or discussion of its validity and taxonomic placement. More recently, phylogenetic analyses based on molecular sequence data that included specimens of Flapocephalus have supported Flapocephalus as a distinct genus allied with the Polypocephalidae Meggitt, 1924.

Psychopathology
September 2025
Background: According to the standard definition, a hallucination is 1) a perceptual experience occurring in the absence of a relevant perceptual object, 2) it has the sense of reality of a veridical perception, and 3) it is unwilled and not under voluntary control of the hallucinator. This definition is supposed to encompass all hallucinations, across mental disorders and experiential modalities.
Summary: In this article, we examine the standard definition's validity by comparing visual hallucinations in delirium and auditory verbal hallucinations (AVHs) in schizophrenia, focusing especially on the definition's second criterion, i.

Covering upto 2025Rotenoids are angular hybrid isoflavonoids mainly characterized by an additional six-membered ring between the B and C rings of flavonoids. The extra ring introduces further chemical diversity to the densely substituted precursors, isoflavonoids, making rotenoids a significant group of compounds within the plant kingdom.
