Distinct pathophysiological mechanisms of Heterometrus laoticus and Lychas mucronatus scorpion venoms on cardiovascular and renal functions

  Distinct pathophysiological mechanisms of Heterometrus laoticus and Lychas mucronatus scorpion venoms on cardiovascular and renal functions Abstract Background:    Heterometrus laoticus and Lychas mucronatus are widely distributed in Southeast Asia, yet their pathophysiological effects of both venoms remain poorly characterized due to low human fatality rates. This study compared their venom compositions and acute cardiovascular and renal effects. Methods:   Anesthetized male New Zealand White rabbits were monitored for blood pressure (BP), heart rate (HR), and renal clearance following intravenous administration of crude venom (0.5 mg/kg). Venom components were identified via LC-MS/MS, and hematological/biochemical parameters were assessed. Results:    H. laoticus venom induced a rapid, transient hypotension ( p < 0.05), followed by a mild, prolonged hypotensive phase (up to 120 min). Conversely, L. mucronatus venom elicited a biphasic response: ...

Annotated checklist of imported non-native spider (Araneae) taxa recorded in the United Kingdom 1800–2024

Abstract
An annotated checklist of non-native spiders historically and contemporaneously known to have been accidently imported into the United Kingdom is given, a total of 35 families, 103 genera, and 131 species are accepted for the checklist. New records, based on material sent to the author over the last decade and further historical museum specimens examined, comprise 35 newly recorded species. Of these, three also represent the first records of their respective genera, and two the first records of their respective families. Five new taxonomic acts are proposed: Clubiona facilis O. Pickard Cambridge, 1911, stat. rev. (Clubionidae); Bolostromus suspectus O. Pickard-Cambridge, 1911, nomen dubium (Cyrtaucheniidae); Lathys lepida O. Pickard-Cambridge, 1909, nomen dubium (Dictynidae); Orchestina dubia O. Pickard-Cambridge, 1911; nomen dubium (Oonopidae); and Melos bicolor O. Pickard-Cambridge, 1900, nomen dubium (Theridiidae).
