Antimicrobial Peptides (AMPs)

Antimicrobial peptides (AMPs) are extensive group of molecules that produced by variety tissues of invertebrate, plants, and animal species which play an important role in their immunity response. AMPs have different classifications such as; biosynthetic machines, biological sources, biological functions, molecular properties, covalent bonding patterns, three dimensional structures, and molecular targets.These molecules have multidimensional properties including antimicrobial activity, antiviral activity, antifungal activity, anti-parasite activity, biofilm control, antitumor activity, mitogens activity and linking innate to adaptive immunity that making them promising agents for therapeutic drugs. In spite of this advantage of AMPs, their clinical developments have some limitation for commercial development. But some of AMPs are under clinical trials for the therapeutic purpose such as diabetic foot ulcers, different bacterial infections and tissue damage. In this review, we emphasized on the source, structure, multidimensional properties, limitation and therapeutic applications of various antimicrobial peptides

Investigation the UV Effect on Uranium Bioleaching Process in Acidithiobacillus sp FJ2 ‎and its Possible Consequences on the CoxB Gene Sequence ‎

Introduction: The increasing use of uranium as a suitable source of energy in various industries has led to the depletion of high-grade uranium mines in different countries. Today, the uranium bioleaching process has been used in different countries for easy and cheap access to uranium. In this process, microorganisms are used to extract uranium from low-grade mines. Materials and methods: The Acidithiobacillus sp. FJ2 bacterium was exposed to UV radiation. Then, the uranium bioleaching process was conducted in the presence of bacteria exposed to UV and non-exposed bacteria. In followings, this gene was amplified by PCR technique after DNA extraction from bacterial species and coxB gene primer design. Subsequent to gene sequencing and editing with bioedit software, the final sequence of the coxB gene was determined from both bacterial species. Later than, the sequences were examined and compared to prove the presence or absence of the mutation in the radiation sample. Results: The amount of uranium extraction in the presence of bacteria exposed to UV reached to 100% on the second day at the 5% pulp density, whereas the 96.36% extraction yield was obtained on the thirteenth day in pulp density of 50%. This amount was recorded in an unexposed bacterium, in the third and thirteenth days at 5& 50% pulp densities, respectively. The coxB gene sequence was identical in both bacterial specimens. Discussion and conclusion: In this study, UV irradiation to Acidithiobacillus sp. FJ2 increased the rate of uranium bioleaching in the pulp density of 5%, whereas uranium extraction yield was sustained in the 50% pulp density. These effects were independent to the coxB gene

Host Plant-Associated Population Variation in the Carob Moth Ectomyelois ceratoniae in Iran: A Geometric Morphometric Analysis Suggests a Nutritional Basis.

The carob moth, Ectomyelois ceratoniae (Zeller, 1839) (Lepidoptera: Pyralidae), is the most important pest of pomegranate in Iran. As it has been rarely recorded on other host plants, control methods have mostly been focused on its populations on pomegranate. In this study, shapes and sizes of wings were compared in populations on 4 host plants (pomegranate, fig, pistachio and walnut) using a landmark-based geometric morphometric method, and analysis of partial warp scores and centroid sizes. The results showed significantly smaller wing size in populations on pomegranate and a significant host plant-associated shape difference among populations as a consequence of allometric growth. This suggests that the wing size and shape differences among test populations may not have a genetic basis and could happen because of differences in the nutritional content of host plants. The results of the analysis suggest that the female carob moth lays her eggs on host plants that provide suitable conditions for hatching. The larger size of moths on hosts other than pomegranate showed that some host plants such as fig, pistachio and walnut can provide for increased stored nutritional reserves by larvae that may result in more successful over-wintering and higher fecundity in adults. This suggests that in spite of the more extensive activity of carob moth on pomegranate in Iran, populations on other host plants can have an important effect on expanding pest population sizes in following years which should be considered in control methods
