Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

The Aromatic Head Group of Spider Toxin Polyamines Influences Toxicity to Cancer Cells

Toxins, 2017
Spider venoms constitute incredibly diverse libraries of compounds, many of which are involved in prey capture and defence. Polyamines are often prevalent in the venom and target ionotropic glutamate receptors. Here we show that a novel spider polyamine,

Judaism, Philo, and Hegel's Theology

Modern Theology, EarlyView.
Abstract Hegel displays consistent interest in Judaism, but his presentation seems to differ widely between his earlier and later writings. Contemporary scholarly interpretations of this apparent change also differ widely. In this article, I present the interpretive problem as one of continuity‐discontinuity, and place the major scholarly treatments ...

Venomic and pharmacological activity of Acanthoscurria paulensis (Theraphosidae) spider venom

Toxicon, 2013
In the present study we conducted proteomic and pharmacological characterizations of the venom extracted from the Brazilian tarantula Acanthoscurria paulensis, and evaluated the cardiotoxicity of its two main fractions. The molecular masses of the venom components were identified by mass spectrometry (MALDI-TOF-MS) after chromatographic separation ...

Middlebrow Aesthetics: An Explanation and Defense

Pacific Philosophical Quarterly, EarlyView.
ABSTRACT We offer a philosophical account of the middlebrow as a theoretical category to do explanatory and critical work in aesthetics. On our account, the middlebrow ought to be understood as aspirational popular art. That is, it is art which aspires both to be popular (in a distinctive sense), and at the same time to be something more than popular ...

Regulating Autonomous Weapon Systems: Searching for African Solutions to Regional and Global Problems

Regulation &Governance, EarlyView.
ABSTRACT Lethal autonomous weapon systems (LAWS), while offering strategic advantages in warfare, pose significant ethical, legal, and security risks, especially for countries in the Global South. This article examines how a philosophical perspective, rooted in African ethical and political thought, can enrich regional and global debates on regulating ...

CSTX-1, a toxin from the venom of the hunting spider Cupiennius salei, is a selective blocker of L-type calcium channels in mammalian neurons [PDF]

, 2007
The inhibitor cystine-knot motif identified in the structure of CSTX-1 from Cupiennius salei venom suggests that this toxin may act as a blocker of ion channels.

Obesity and the Politics of Taddeo di Bartolo's Inferno

Renaissance Studies, EarlyView.
ABSTRACT This paper examines Taddeo di Bartolo's depiction of Hell in the Collegiata di Santa Maria Assunta, the mother church of San Gimignano. In a striking departure from similar scenes of the period, the fresco, painted in the early fifteenth century, emphasizes the obesity of the sinners—suggesting a deliberate visual critique.

Spider Neurotoxins, Short Linear Cationic Peptides and Venom Protein Classification Improved by an Automated Competition between Exhaustive Profile HMM Classifiers

Toxins, 2017
Spider venoms are rich cocktails of bioactive peptides, proteins, and enzymes that are being intensively investigated over the years. In order to provide a better comprehension of that richness, we propose a three-level family classification system for ...

Molecular basis of the remarkable species selectivity of an insecticidal sodium channel toxin from the African spider Augacephalus ezendami [PDF]

, 2016
The inexorable decline in the armament of registered chemical insecticides has stimulated research into environmentally-friendly alternatives. Insecticidal spider-venom peptides are promising candidates for bioinsecticide development but it is ...
