New Lower Cretaceous basal mantodean (Insecta) from the Crato Formation (NE Brazil)

Geologica Carpathica, 2014
Mantodea are very rare in the fossil record. 28 fossil species are reported since the earliest occurrence of mantodeans in the Upper Jurassic (Tithonian). Here, I describe Cretophotina santanensis n. sp. from the Aptian (Lower Cretaceous) Crato Formation

Assessment of the Acute Toxicity and Anxiolytic‐Like Effect of α‐Humulene in Adult Zebrafish (Danio rerio)

Chemistry &Biodiversity, Volume 23, Issue 7, July 2026.
The monocyclic sesquiterpene α‐humulene elicited a significant anxiolytic‐like behavior in adult zebrafish and no observable acute toxicity. Pharmacological dissection suggested that this effect is independent of the benzodiazepine (BZD) binding site on the gamma‐aminobutyric acid (GABA) type A receptor (GABAAR), but it depends on the serotonin type 3 ...

Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...

Gastroprotective Effects of Hexanic Extract of the Leaves of Spondias purpurea and Its Underlying Mechanism of Action

Journal of Food Process Engineering, Volume 49, Issue 6, June 2026.
Histopathological analysis of gastric mucosa stained with HE and PAS of rats submitted to induction of ulcers with acetic acid. The animals were treated orally with vehicle (injured control), ranitidine, and SpHE (25 mg/kg) for 14 days. In A and B, observe preserved mucosa and submucosal layers (black asterisk) and presence of the barrier protection of

Anxiolytic and Memory Protective Effects of Withanolide D Isolated From Acnistus arborescens in Adult Zebrafish

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Withanolide D Exhibits Anxiolytic and Memory‐Protective Effects. ABSTRACT This study evaluated the anxiolytic and memory‐protective effects of withanolide D in adult zebrafish (Danio rerio). The compound was administered at doses of 4, 20, and 40 mg/kg and showed no signs of toxicity after 96 h of observation at any of the doses tested.

Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Cochlichnus anguineus is an ichnotaxon recognized for its distinctive regular wavy morphology. It is a characteristic trace fossil typically associated with aquatic and marginal aquatic environments. However, in this study we examine its unusual occurrence in the aeolian sandstones of the Botucatu Formation (Lower Cretaceous, Paraná Basin ...
