Ecosystem services provided by spiders. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.

Spider neurotoxins targeting voltage-gated sodium channels [PDF]

, 2005
The voltage-gated sodium (Nav) channel is a target for a number of drugs, insecticides, and neurotoxins. These bind to at least seven identified neurotoxin binding sites and either block conductance or modulate sodium channel gating and/or kinetics.

An Economic Dilemma between Molecular Weapon Systems May Explain an Arachno-Atypical Venom in Wasp Spiders (Argiope bruennichi)

Biomolecules, 2020
Spiders use venom to subdue their prey, but little is known about the diversity of venoms in different spider families. Given the limited data available for orb-weaver spiders (Araneidae), we selected the wasp spider Argiope bruennichi for detailed ...

Potency Testing of Venoms and Antivenoms in Embryonated Eggs: An Ethical Alternative to Animal Testing

Toxins, 2021
Venoms are complex mixtures of biologically active molecules that impact multiple physiological systems. Manufacture of antivenoms (AVs) therefore requires potency testing using in vivo models to ensure AV efficacy. As part of ongoing research to replace

Venom-gland transcriptomics and venom proteomics of the Tibellus oblongus spider

Scientific Data, 2023
AbstractThe Tibellus oblongus spider is an active hunter that does not spin webs and remains highly underinvestigated in terms of the venom composition. Here, we describe venom glands transcriptome and venom proteome analysis for unveiling the polypeptide composition of Tibellus oblongus spider venom.

Toward a unified understanding of people’s aversion to nature: biophobia

Frontiers in Ecology and the Environment, EarlyView.
Human–nature relationships are often framed positively, but research rarely addresses biophobia, the aversion to nature. However, negative relationships with nature are likely to become more widespread following societal and environmental changes, with serious implications for public health and conservation efforts.

Hypofractionated versus conventionally fractionated radiotherapy for breast cancer in patients with reconstructed breast

Malignancy Spectrum, EarlyView.
Abstract Breast cancer (BC) is the most prevalent and destructive tumor in developing countries. The implementation of mammography screening programs has enabled access to appropriate therapeutic interventions, including adjuvant endocrine therapy and breast‐conserving surgery; earlier diagnosis translates into a wider survival‐rate range, making ...

Peptide Toxins in Solitary Wasp Venoms

Toxins, 2016
Solitary wasps paralyze insects or spiders with stinging venom and feed the paralyzed preys to their larva. Accordingly, the venoms should contain a variety of constituents acting on nervous systems.
