SCORPIONS, SCORPIONISM, LIFE HISTORY STRATEGIES AND PARTHENOGENESIS

open access: yesJournal of Venomous Animals and Toxins, 1995
Recently public health problems resulting from scorpion stings have shown an alarming increase in various tropical and subtropical countries such as Brazil, Mexico, Tunisia and Morocco. In some regions of Brazil, particularly in the States of Minas Gerais, Sao Paulo, Bahia, Goias and the Federal District, more than 6000 scorpion stings with over 100 ...

Calcium regulation of muscle spindle mechanosensory afferent function

open access: yesExperimental Physiology, EarlyView.
Abstract Extracellular calcium is crucial for the normal function of muscle spindle sensory afferents. They express multiple calcium buffering proteins. Extracellular calcium is essential for recycling of synaptic‐like vesicles (SLVs) in the terminals and for the stretch‐evoked inward calcium current of the receptor potential.

Phosphorescent Animal Forms of Arkansas [PDF]

open access: yes, 1971
Two phosphorescent animal forms, Euryurus sp. and Centruroides vittatus, were collected with a black light in an attempt to collect phosphorescent spiders. Both the millipede and the scorpion were easily observed by the bright phosphorescent yellow color

Anti‐Thrombotic Effect of Hemp Seed Peptides in Zebrafish by Dual Regulation of vegfr1 Signaling and Caspase‐3‐Mediated Apoptosis

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
Characterize the thrombin‐inhibitory capacity of hemp seed peptides. Evaluate antithrombotic efficacy through hemodynamic and vascular parameters. Elucidate mechanisms via vegfr1 and caspase‐3 gene expression analysis. ABSTRACT This study aimed to investigate the antithrombotic activity of hemp seed peptides derived from trypsin hydrolysates and ...

Crystal structures of Escherichia coli glucokinase and insights into phosphate binding

open access: yesActa Crystallographica Section F, Volume 81, Issue 8, Page 332-337, August 2025.
This work presents the structure of apo Escherichia coli glucokinase (ecGLK) bound with sulfate, a phosphate mimic, and the structure of ecGLK in complex with both glucose and phosphate, implying a role for phosphate in regulating the glucokinase activity.Here, we report the crystal structure of Escherichia coli glucokinase (GLK), which has phosphate ...
