Proteomic endorsed transcriptomic profiles of venom glands from Tityus obscurus and T. serrulatus scorpions. [PDF]

PLoS ONE, 2018
Except for the northern region, where the Amazonian black scorpion, T. obscurus, represents the predominant and most medically relevant scorpion species, Tityus serrulatus, the Brazilian yellow scorpion, is widely distributed throughout Brazil, causing ...

An engineered scorpion toxin analogue with improved Kv1.3 selectivity displays reduced conformational flexibility

Scientific Reports, 2015
The voltage-gated Kv1.3 K+ channel plays a key role in the activation of T lymphocytes. Kv1.3 blockers selectively suppress immune responses mediated by effector memory T cells, which indicates the great potential of selective Kv1.3 inhibitors in the ...

Subtype Specificity of β-Toxin Tf1a from Tityus fasciolatus in Voltage Gated Sodium Channels

Toxins, 2018
Scorpion venoms are a complex mixture of components. Among them the most important are peptides, which presents the capacity to interact and modulate several ion channel subtypes, including voltage-gated sodium channels (NaV).

Scorpion envenomation-induced acute thrombotic inferior myocardial infarction

Türk Kardiyoloji Derneği Arşivi, 2016
The occurrence of a serious cardiac emergency following scorpion envenomation has rarely been reported and, when so, mostly presented as non-ST segment elevation myocardial infarction, cardiogenic shock, or myocarditis.

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

Phytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.

Structural and Functional Elucidation of Peptide Ts11 Shows Evidence of a Novel Subfamily of Scorpion Venom Toxins

Toxins, 2016
To date, several families of peptide toxins specifically interacting with ion channels in scorpion venom have been described. One of these families comprise peptide toxins (called KTxs), known to modulate potassium channels.

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

Environmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,
