Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin
Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

A Survey for Deep Reinforcement Learning Based Network Intrusion Detection
Applied AI Letters, Volume 7, Issue 2, June 2026.This paper surveys deep reinforcement learning (DRL) for network intrusion detection, evaluating model efficiency, minority attack detection, and dataset imbalance. Findings show DRL achieves state‐of‐the‐art results on public datasets, sometimes surpassing traditional deep learning.

Microstructural Evidence for Early Childhood Stress in a Community in Transition at Hisban, Jordan
American Journal of Biological Anthropology, Volume 190, Issue 2, June 2026.ABSTRACT Objectives Identification of stress across infancy and childhood can reflect maternal and environmental influences on early life health. In the 19th century community of Hisban, many infants died before 2 years of age with evidence of metabolic disease, including rickets, that likely ties with maternal health.

Snake Venom Gland Organoids [PDF]
Cell, 2020 Wnt dependency and Lgr5 expression define multiple mammalian epithelial stem cell types. Under defined growth factor conditions, such adult stem cells (ASCs) grow as 3D organoids that recapitulate essential features of the pertinent epithelium. Here, we establish long-term expanding venom gland organoids from several snake species.

Venom glands in scatophagid fish
Toxicon, 1970Venom glands have been demonstrated in scatophagid fishes for the first time. Six specimens of Scatophagus argus, from 62 mm to 296 mm in standard length, possessed a pair of venom glands accommodated in paired antero-lateral grooves in each fin spine. The venom glands of the larger specimens were shorter than those of the smaller fishes. In Selenotoca

Unmasking venom gland transcriptomes in reptile venoms
Analytical Biochemistry, 2002While structural studies of reptile venom toxins can be achieved using lyophilized venom samples, until now the cloning of precursor cDNAs required sacrifice of the specimen for dissection of the venom glands. Here we describe a simple and rapid technique that unmasks venom protein mRNAs present in lyophilized venom samples. To illustrate the technique

Combined snake venomics and venom gland transcriptomic analysis of Bothropoides pauloensis
Journal of Proteomics, 2012Unraveling the repertoire of venom toxins of Bothropoides pauloensis was assessed by snake venomics and venom gland transcriptomic surveys. Both approaches yielded converging overall figures, pointing to metalloproteinases (~37%), PLA(2)s (26-32%), and vasoactive (bradykinin-potentiating) peptides (12-17%) as the major toxin classes.

Viperid venom glands with defective venom production. Morphological study
Toxicon, 2013The venom of viperid snakes is collected monthly at Butantan Institute for research purposes and production of antivenoms. Here we describe histological and ultrastructural changes on Crotalus durissus terrificus and Bothrops sp. venom glands with defective venom production.
