Alginate-magnetic short nanofibers 3D composite hydrogel enhances the encapsulated human olfactory mucosa stem cells bioactivity for potential nerve regeneration application.

The design of 3D hydrogel constructs to elicit highly controlled cell response is a major field of interest in developing tissue engineering. The bioactivity of encapsulated cells inside pure alginate hydrogel is limited by its relatively inertness. Combining short nanofibers within a hydrogel serves as a promising method to develop a cell friendly environment mimicking the extracellular matrix.

Effect of Arsenophonus Endosymbiont Elimination on Fitness of the Date Palm Hopper, Ommatissus lybicus (Hemiptera: Tropiduchidae).

The date palm hopper, Ommatissus lybicus de Bergevin, is one of the most important pests of the date palm in the Middle East and North Africa. This insect uses its needle-like sucking mouthparts to feed on phloem, which is devoid of most essential amino acids and many vitamins. The absence of essential nutrient in its diet is suggested to be ameliorated by endosymbionts in O.

Evaluation of canola cultivars for resistance to Helicoverpa armigera (Lepidoptera: Noctuidae) using demographic parameters.

The cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is one of the most important pests on a wide range of crops worldwide. The antibiotic resistance of 10 canola cultivars ('Sarigol', 'Hayula420', 'Opera', 'Okapi', 'Modena', 'RGS003', 'Zarfam', 'Licord', 'Talaye', and 'SLM046') to H. arimgera was evaluated using demographic parameters including life table, reproduction, development, and adult longevity.
