Summary: Australia has some of the most venomous snakes in the world, and domestic dogs are commonly envenomated by them. However, clinical signs, diagnostic procedures, and treatments of snake envenomations are poorly described. Based on data from veterinary clinics in Queensland, it was found that veterinarians heavily relied on medical history, clinical signs, and diagnostic tests other than snake venom detection kits in order to diagnose and treat snake envenomation cases in dogs.

Summary: AMPD2 is expressed on the surface of human immune cells and may modify inflammatory states by altering the extracellular milieu. The expression of eAMPD2 on monocytes is enhanced after TLR stimulation. Patients with rheumatoid arthritis show significantly higher levels of eAMPD2 expression on PBMCs compared to healthy controls.

Summary: This study investigated the occurrence of myotoxicity following red-bellied black snake envenomation and found that early antivenom administration could reduce the incidence of myotoxicity. The venom concentration profile does not seem to be the main driver for myotoxicity, indicating that additional factors affecting patient sensitivity to snake venom/toxins need to be explored further.

Summary: Sea snake envenoming in Australia, although rare, is associated with significant morbidity and risk of mortality. Early antivenom therapy appears to play a role in preventing severe myotoxicity and should be a treatment goal.

Summary: The vertebrate neuromuscular junction is a specialised synapse composed of a presynaptic region, a postsynaptic skeletal motor endplate area, and perisynaptic Schwann cells that play a significant role in maintaining neuromuscular integrity, transmission, and plasticity. Acetylcholine is the main neurotransmitter at this synapse and is modulated by purinergic neuromodulators. Adenine nucleotides and adenosine, released alongside acetylcholine, regulate transmitter release and expression of ACh receptors via P2Y and P2X receptors. Adenosine, through A1 and A2A receptors, also modulates ACh release by motor nerve terminals. Understanding the complex interplay between purines and neuromuscular transmission is essential for conditions like Myasthenia gravis.

Summary: Snake venom proteins have been developed as potential drugs for treating human diseases despite being responsible for severe injuries. The study evaluated CC-LAAO from Cerastes cerastes snake venom as a potential anti-glioblastoma drug, showing that low concentrations may be safe and have potential in developing anti-glioblastoma agents.

Summary: This study established a rabbit model of subcutaneous envenomation to evaluate the toxicodynamics of various snake venoms and the efficacy of ruthenium-based antivenom administration. The results showed that different snake venoms exhibited diverse toxicodynamic patterns, and the tested antivenoms attenuated venom-mediated coagulopathy. This rabbit model can be used to investigate the onset and severity of envenomation and assess the efficacy of site-directed antivenom.

Summary: This study investigates the use of an enzyme-loaded synthetic hydrogel for local adenosine generation to improve perfusion and inhibit inflammation in peripheral arterial ischemia. Results show that the CD73 hydrogel effectively increases adenosine levels in vivo and improves limb perfusion in animal models, providing a new strategy for future disease treatment.

Summary: This study retrospectively examined venomous snakebites in dogs in South Korea. The study found that snakebites mostly occurred between April and October, from 12 p.m. to 5 p.m. Grassland was the most common location for snakebite incidents, and walking dogs on a leash was the most frequent activity during snakebite occurrences. The main symptoms of snakebite included edema, hemorrhage, erythema, ulceration, and necrosis. The study also found that prompt treatment improved prognosis.

Summary: This retrospective study describes the clinical features and antivenom response of Gloydius snake envenomation in South Korea, finding that rhabdomyolysis is a major effect although not associated with the same risk of clinical deterioration as coagulopathy. Additionally, further investigation is needed to determine the ability of antivenom to ameliorate local swelling and prevent unnecessary antivenom administration in South Korea.

Summary: The study revealed that Naja annulifera venom can activate the complement system, leading to the release of lipid mediators and chemokines, and subsequent pathological reactions. Inhibition of the C5a-C5aR1 axis can mitigate the effects of complement activation. The cyclic peptide antagonist PMX205 can rescue mice from systemic reactions and prevent acute lung injury caused by complement activation.

Summary: This study investigated the nature and severity of venom-induced consumption coagulopathy (VICC) in patients after envenomation by South Korea's snakes, as well as the effectiveness of antivenom for VICC treatment. VICC occurred in approximately one-quarter of snakebite patients in South Korea, with fibrinogen being an early diagnostic marker for complete VICC and clotting factors II and X being involved in VICC. Future investigations should explore the mechanism of VICC from Korean snakebites and the effect of antivenom on VICC.

Summary: This study investigates alterations in purinergic pathways in COVID-19 patients and provides new insights into the immunopathology of the disease. The findings suggest that the purinergic signaling is dysregulated in both mild and severe COVID-19 patients, which may affect immune function. Additionally, increased T-cell apoptosis and decreased purine levels are observed in COVID-19 patients compared to healthy controls.

Summary: In this study, two Streptomyces strains (NE5-10 and Y2F8-2) exhibiting 5'-inosine monophosphate (IMP)-dephosphorylating activity were obtained from soil isolates. The responsible enzyme was purified and the coding sequence was identified in the whole genome sequence of each strain. Phylogenetic analysis showed that the isolated Streptomyces enzymes represent a novel group of bacterial 5'-nucleotidases. Enzymatic characterization revealed differences in optimal temperature and pH, dependence on divalent cations, and substrate specificity between the two Streptomyces enzymes.

Summary: Envenomation by the small, semi-fossorial, front-fanged colubrid Homoroselaps lacteus can cause local edema, lymphadenopathy, and significant subcutaneous loco-regional bruising, possibly due to damage to capillary basement membrane. While local clinical effects may seem dramatic, the small volumes of venom injected make life-threatening effects unlikely.
