AI Article Synopsis

  • Researchers developed an antivenom (HcuAV) derived from horse plasma immunized with sea snake venom, which showed strong effectiveness in lab tests.
  • HcuAV significantly improved survival rates in mice bitten by sea snakes and helped reduce organ damage, indicating its potential for future clinical use.

Article Abstract

Sea snake venom is extremely toxic, and it can induce severe respiratory failure and cause high mortality. The most effective first aid treatment for sea snake bites is to inject antivenom as soon as possible. However, in China, there are only four types of terrestrial snake antivenoms, none of which are effective in the treatment of sea snake bites. In order to develop an antivenom for the dominant species of sea snakes in Chinese seas, venom (HcuV) was chosen as the antigen to immunize horses. From immune plasma, a high-titer antivenom (HcuAV) was prepared. In vitro assessment showed that HcuAV had a cross-neutralizing capacity against HcuV and venom (HcyV). In vivo assessment indicated that HcuAV injection could significantly improve the survival rates of the HcuV and HcyV envenomated mice (0% to 100% and 87.5%, respectively) when it was injected at a sufficient amount within the shortest possible time. In addition, HcuAV could also effectively alleviate multiple organ injuries caused by HcuV. These results provide experimental support for the future clinical application of HcuAV.

Background: Snakebite envenoming is a critical medical emergency and significant global public health issue, with India experiencing the highest annual snakebite deaths. Sea snakes in the Indian Ocean pose a severe threat to rural fishermen due to their potent neurotoxins.

Methods: From December 2020 to December 2021, we conducted surveys at 15 fishing ports in East Medinipur, West Bengal, and Balasore, Odisha, India (between 21.

Article Synopsis
  • Understanding species distributions is crucial in ecology, yet most studies focus on land species; this research investigates the global distribution of sea snakes, emphasizing abiotic factors.
  • The study assesses the influence of various marine environmental variables and explores the asymmetry of realized thermal niches, which affects species' ecological distribution.
  • Key findings reveal that temperature, silicate, nitrate, salinity, and phosphate are the primary factors influencing sea snake distribution patterns across different taxonomic levels and spatial resolutions.

At deep-sea hydrothermal vents, deprived of light, most living communities are fueled by chemosynthetic microorganisms. These can form symbiotic associations with metazoan hosts, which are then called holobionts. Among these, two endemic co-occurring shrimp of the Mid-Atlantic Ridge (MAR), and are colonized by dense and diversified chemosynthetic symbiotic communities in their cephalothoracic cavity and their digestive system.

Purpose: To explore the impact of the snake-eye appearance (SEA) on the efficacy of anterior cervical discectomy and fusion (ACDF) in treating Degenerative Cervical Myelopathy (DCM).

Methods: A total of 316 Patients were divided into three groups, those with SEA were in the SEA group, and those with the absence of SEA were in the non-SEA group. Meanwhile, in the non-SEA group, patients with grade 1 or 2 increased signal intensity (ISI) on T2-weighted MRI were in the ISI group, and the remaining patients without ISI were in the non-ISI group.
