ANTITUMOR EFFECT OF SNAKE VENOMS

open access: yesJournal of Venomous Animals and Toxins, 1996
The search for biological antitumor agents has been pursued for over half a century. Snake venom has been shown to possess a wide spectrum of biological activities. The objectives of the present review are to evaluate the existing controversies on this subject published in a number of papers and to propose probable explanations for the phenomena ...

Preparing for the worst: The irrationality of emotionally recalcitrant reasoning

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract The question of what exactly is irrational about recalcitrant emotions—those that occur in tension or conflict with our beliefs—has been widely debated. Sabine Döring claims that such irrationality only emerges if we act on our recalcitrant emotion or engage in emotion‐relevant reasoning in light of it.

Conservation beyond biopolitics: Vulnerability and abundance in Chennai's nature‐cultures

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract This paper examines a breadth of natures and nature practices in Chennai, India, to illuminate the socio‐material processes that undermine some natures even while supporting others, and to highlight paradoxical responses to nonhuman agencies and resilience within the domain of ecological concern.

Emulating duration and curvature of coral snake anti-predator thrashing behaviors using a soft-robotic platform [PDF]

open access: yesarXiv, 2020
This paper presents a soft-robotic platform for exploring the ecological relevance of non-locomotory movements via animal-robot interactions. Coral snakes (genus Micrurus) and their mimics use vigorous, non-locomotory, and arrhythmic thrashing to deter predation.

In Vitro Structure–Activity Relationship Stability Study of Antisense Oligonucleotide Therapeutics Using Biological Matrices and Nucleases

open access: yesPharmacology Research &Perspectives, Volume 13, Issue 3, June 2025.
ABSTRACT The primary degradation pathway for antisense oligonucleotides (ASOs) involves endonuclease and exonuclease‐mediated breakdown. The effect of various chemical modifications on the stability of oligonucleotides has not been systematically investigated.

Effect of Vipera ammodytes ammodytes Snake Venom on the Human Cytokine Network

open access: yesToxins, 2018
Local inflammation is a well-known symptom of envenomation by snakes of the family Viperidae, attributed primarily to the phospholipase A2s, metalloproteinases and L-amino acid oxidases contained in their venom.

Variational approximations to homoclinic snaking [PDF]

open access: yes, 2010
We investigate the snaking of localised patterns, seen in numerous physical applications, using a variational approximation. This method naturally introduces the exponentially small terms responsible for the snaking structure, that are not accessible via standard multiple-scales asymptotic techniques.

Early cardiovascular collapse after envenoming by snakes in Australia, 2005–2020: an observational study (ASP‐31)

open access: yesMedical Journal of Australia, Volume 222, Issue 6, Page 313-317, April 2025.
Abstract Objectives To investigate the frequency, timing, and characteristics of cardiovascular collapse after snakebite in Australia, and the complications of collapse following envenoming. Study design Observational study; analysis of prospectively collected demographic and clinical data.

Super‐Tough Silk: The Potential of Knots in Evolved Spiders

open access: yesAdvanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...
