Genetic Diversity of Scorpions (Scorpionidae: Buthidae) in Khuzestan, Iran.

The genus of scorpion is one of the few medically important scorpions in Iran. This study assessed the genetic relationship analysis of the cytochrome c oxidase subunit I (COXI) and 12sRNA genes and morphometric parameters among the population of in Khuzestan. Morphological analysis using the ANOVA T-test with a significance level of P-value less than 0.

Phylogenetic Relationships of Scorpion Based on Sequences of Internal Transcribed Spacer 2 Gene from Khuzestan Province, Iran.

Buthidae family includes scorpions with highly potent venom such as is important due to the prevalence of scorpion stings in Khuzestan Province, Iran. Morphometric comparison of males and females (n=5 each) showed that the body and carapas of the females were longer and wider (32.57±0.

Molecular Characterization of a Three-disulfide Bridges Beta-like Neurotoxin from Androctonus crassicauda Scorpion Venom.

Scorpion venom is the richest source of peptide toxins with high levels of specific interactions with different ion-channel membrane proteins. The present study involved the amplification and sequencing of a 310-bp cDNA fragment encoding a beta-like neurotoxin active on sodium ion-channel from the venom glands of scorpion Androctonus crassicauda belonging to the Buthidae family using reverse transcription polymerase chain reaction (RT-PCR) technique. The amplified complementary DNA (cDNA) fragment had a coding sequence of 240 bp.

Comparative characterization of two galectins excreted-secreted from intestine-dwelling parasitic versus free-living females of the soil-transmitted nematode Strongyloides.

Helminths are complex pathogens that ensure their long-term survival by influencing the immune responses of their host. Excretory/secretory products (ESP) can exert immunoregulatory effects which foster parasite survival. Galectins represent a widespread group of β-galactoside-binding proteins which are involved in a multitude of biological processes operative in parasite-host interaction.

Investigating of four main carbapenem-resistance mechanisms in high-level carbapenem resistant Pseudomonas aeruginosa isolated from burn patients.

Background: Pseudomonas aeruginosa is an opportunistic pathogen involved in many infections. Carbapenem-resistant P.aeruginosa has emerged as an important cause of infection in different hospitals worldwide.
