Varespladib (LY315920) Appears to Be a Potent, Broad-Spectrum, Inhibitor of Snake Venom Phospholipase A2 and a Possible Pre-Referral Treatment for Envenomation

Toxins, 2016
Snakebite remains a neglected medical problem of the developing world with up to 125,000 deaths each year despite more than a century of calls to improve snakebite prevention and care.

Investigating snake venom variation to mitigate snakebite envenomation in Indonesia [PDF]

BIO Web of Conferences
Snakebite envenoming is one of the neglected tropical diseases and is still rarely studied in Indonesia. The high diversity of venomous snakes in Indonesia is one of the challenges.

VENOM: Text-driven Unrestricted Adversarial Example Generation with Diffusion Models [PDF]

arXiv
Adversarial attacks have proven effective in deceiving machine learning models by subtly altering input images, motivating extensive research in recent years. Traditional methods constrain perturbations within $l_p$-norm bounds, but advancements in Unrestricted Adversarial Examples (UAEs) allow for more complex, generative-model-based manipulations ...

Partially Directed Snake Polyominoes [PDF]

arXiv, 2013
The goal of this paper is to study the family of snake polyominoes. More precisely, we focus our attention on the class of partially directed snakes. We establish functional equations and length generating functions of two dimensional, three dimensional and then $N$ dimensional partially directed snake polyominoes.

A Comprehensive View of the Structural and Functional Alterations of Extracellular Matrix by Snake Venom Metalloproteinases (SVMPs): Novel Perspectives on the Pathophysiology of Envenoming

Toxins, 2016
Snake venom metalloproteinases (SVMPs) affect the extracellular matrix (ECM) in multiple and complex ways. Previously, the combination of various methodological platforms, including electron microscopy, histochemistry, immunohistochemistry, and Western ...

Distinct regulatory networks control toxin gene expression in elapid and viperid snakes

BMC Genomics
Background Venom systems are ideal models to study genetic regulatory mechanisms that underpin evolutionary novelty. Snake venom glands are thought to share a common origin, but there are major distinctions between venom toxins from the medically ...

A general approach to enhance the survivability of backdoor attacks by decision path coupling [PDF]

arXiv
Backdoor attacks have been one of the emerging security threats to deep neural networks (DNNs), leading to serious consequences. One of the mainstream backdoor defenses is model reconstruction-based. Such defenses adopt model unlearning or pruning to eliminate backdoors. However, little attention has been paid to survive from such defenses.

Snake graph calculus and cluster algebras from surfaces II: Self-crossing snake graphs [PDF]

arXiv, 2014
Snake graphs appear naturally in the theory of cluster algebras. For cluster algebras from surfaces, each cluster variable is given by a formula which is parametrized by the perfect matchings of a snake graph. In this paper, we continue our study of snake graphs from a combinatorial point of view.

Subdivision based snakes for contour detection [PDF]

arXiv, 2018
In this paper we propose a method for computing the contour of an object in an image using a snake represented as a subdivision curve. The evolution of the snake is driven by its control points which are computed minimizing an energy that pushes the snake towards the boundary of the interest region.
