Identification of Knockdown Resistance Mutations in the Cimex hemipterus (Hemiptera: Cimicidae) in Iran.

The worldwide resurgence of tropical bed bug Cimex hemipterus beginning in the late 1990s has led to growing concern. Molecular data on pyrethroid resistance, which is essential for the control strategies, is unknown for C. hemipterus in Iran.

The Prevalence of Parasitic Contamination of Fresh Vegetables in Tehran, Iran.

Objective: Parasitic diseases have created numerous health and economic problems in developing and developed countries. One of the most prevalent ways of transmitting diseases is by consuming raw vegetables that are contaminated with parasites. With respect to the importance of healthy vegetable consumption, an awareness of vegetable status helps prevent infection.

Prevalence and molecular characterization of Cryptosporidium spp. and Giardia intestinalis in household dogs and cats from Shiraz, Southwestern Iran.

In the present study, a total of 615 fecal samples from veterinary clinics were screened by microscopy for the presence of Cryptosporidium and Giardia oocysts. Molecular genotyping of Cryptosporidium and Giardia were carried out using PCR and sequence analysis. Overall, Cryptosporidium and Giardia oocysts were detected in the 0.

Suramin could block the activity of Arabinono-1, 4-lactone oxidase enzyme from Leishmania donovani: structure-based screening and molecular dynamics analyses.

Background: Leishmania donovani, a parasitic protozoan causing visceral leishmaniasis, can lead to a dangerous and often fatal disease in humans. Current treatment for leishmaniasis may have severe side effects, low efficacy and high cost, hence an immediate need for new efficient drugs is essential. Arabinono-1, 4-lactone oxidase enzyme from Leishmania donovani (LdALO), which catalyzes the last step of the ascorbate biosynthesis pathway, has been considered as a potential target for antileishmanial drugs design.

Retraction Note: Effects of Nano-particles on Histo-pathological changes of the fish.

Cryotherapy of cutaneous leishmaniasis caused by in BALB/c mice: A comparative experimental study.

Background & Objectives: Leishmania parasites are sensitive to very low temperature. Cryotherapy is considered as an alternative to the existing pentavalent antimonials, for local treatment of cutaneous leishmaniasis (CL). Normally, liquid nitrogen (N) at a temperature of -196 °C, is used in cryotherapy of CL, but it's efficacy is not consistent.

Bioinformatics analysis of single and multi-hybrid epitopes of GRA-1, GRA-4, GRA-6 and GRA-7 proteins to improve DNA vaccine design against .

, is a causative agent of morbidity and mortality in immunocompromised and congenitally-infected individuals. Attempts to construct DNA vaccines against using surface proteins are increasing. The dense granule antigens are highly expressed in the acute and chronic phases of infection and considered as suitable DNA vaccine candidates to control toxoplasmosis.

Stimulated and Unstimulated Saliva Levels of Calcium and Magnesium in Giardiasis.

Giardia lamblia causes malabsorption. The aim of this study was to evaluate serum and saliva calcium and magnesium levels in patients with giardiasis. Thirty patients with giardiasis as a case and 30 person without giardiasis as a control group were enrolled.

Effects of Toxoplasma gondii infection on anxiety, depression and ghrelin level in male rats.

The aim of the present study was to determine the effects of Toxoplasma gondii (T. gondii) infection on anxiety, depression and ghrelin level in male rats. Twenty four male rats were assessed in two equal groups.

Effects of Nano-particles on Histo-pathological changes of the fish.

Regarding fast development of the nanotechnology and the probably of it's side effects on aquatic body organs, this study investigate the effects of nanosilver administration on histology of gill, kidney and biochemical parameters in common carp. The silver nanoparticles were synthesized in a one-step reduction process in an aqueous solution. 60 O.

Anti-Toxoplasma gondii Antibody Levels in Blood Supply of Shiraz Blood Transfusion Institute, Iran.

Background: The prevalence of Toxoplasma gondii infection in the blood donors has been poorly studied. The aim of this study was to assess the prevalence of acute and chronic toxoplasmosis in blood products.

Methods: A total of 250 blood products (112 fresh frozen plasma and 138 packed cells) in the Blood Transfusion Institute, Shiraz, Iran were tested for specific T.
