  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: ...

Integrative taxonomy describes a new species of the genus Dicranolasma Sørensen (Opiliones: Dicranolasmatidae) from Turkey

ABSTRACT

A new species, Dicranolasma gumushanensis sp. n., is described from the Gümüşhane Province of the northeastern region of Turkey, based on morphological and genetic evidence. The newly described species differs from similar species within the genus, particularly due to morphological characteristics such as the structure of the chelicerae and genitalia, and its molecular characteristics. A detailed description and diagnostic characteristics of the new species are provided, in addition to images of its body in dorsal view, chelicerae, pedipalps and genitalia. The nuclear (28S rRNA) and mitochondrial (COI) gene regions of the species were sequenced, revealing its phylogenetic relationships within the genus Dicranolasma.
