Polysaccharides from marine algae are one novel source of plant defense elicitors for alternative and eco-friendly protection against phytopathogens. The effect exopolysaccharides (EPS) produced by Porphyridium sordidum on elicitation Arabidopsis thaliana responses Fusarium oxysporum was evaluated. Firstly, in order to enhance EPS production, a Box-Behnken experimental design carried out optimize NaCl, NaNO3 MgSO4 concentrations the culture medium microalgae. A maximum production (2.45 g/L)...
Abstract Nasopharyngeal carcinoma (NPC) in Tunisia is characterized by its bimodal age distribution involving juvenile patients of 10–24 years and adult 40–60 years. Three serological techniques were compared for primary diagnosis (N = 117) post‐treatment monitoring 21) NPC separated two groups. Immunofluorescence assay (IFA) was used as the “gold standard” detection IgG IgA antibodies reactive with Epstein‐Barr virus (EBV) early (EA) viral capsid (VCA) antigens. Results ELISA measuring...
Microbial extracellular polymeric substances (EPS) have recently emerged as significant contributors in diverse biotechnological applications. Extracellular (EPS), produced by a Navicula salinicola strain, been studied for potential applications specific heavy metal (lead (Pb II)) removal from wastewater. The optimisation of operational parameters, mainly pH, Pb and EPS concentrations, using the Box–Behnken design (BBD) was undertaken to enhance lead uptake. higher adsorption capacity...
Heavy metals are one of the main threats to marine life and ecosystems any remedial action in that regard is urgently required. The aim this work study bioremoval cadmium, chromium lead a microalgae strain Chlorococcum dorsiventrale isolated from Tunisian coastal waters along with assessing its enzymatic molecular responses. were tested artificial seawater evaluate their capacity for phycoremediation an aquatic environment. This tolerated exposure Cd (II), Cr (VI), Pb (II) was able grow 14...
Microalgae are capable of generating numerous metabolites that possess notable biological activities and hold substantial promise for various industrial applications. Nevertheless, the taxonomic diversity these photosynthetic microorganisms has not received thorough investigation. Using 18S rRNA encoding gene, a recently discovered strain originating from Tunisian coast (the governorate Mahdia) was identified as member
Microalgae have been poorly investigated for new-lipolytic enzymes of biotechnological interest. In silico study combining analysis sequences homologies and bioinformatic tools allowed the identification preliminary characterization 14 putative lipases expressed by Chlorella vulagaris. These proteins different molecular weights, subcellular localizations, low instability index range at least 40% sequence identity with other microalgal lipases. Sequence comparison indicated that catalytic...
Dehydrins (DHNs) are among the most common proteins accumulated in plants under water-related stress. They typically contain at least three conserved sequences designated as Y-, S- and K-segments. The present work aims to highlight role of K-segments plant tolerance biotic abiotic stresses. For this purpose, transgenic Arabidopsis thaliana (L.) Heyhn. lines expressing distinct wheat (Triticum aestivum L.) DHN-5 truncated constructs with or without were generated. Our results showed that...
Microalgae are attracting considerable interest worldwide. In the present study, two native microalgae strains isolated from Tunisian cost were identified as Chlamydomonas sp. and Navicula We characterized their pigment protein contents, well carbohydrate lipid productivity. The predominant fatty acids found to be α-linolenic acid (C18:3n-3) palmitoleic (C16:1n-7) for respectively. methanol extracts showed important in vitro antibacterial activity against all tested gram negative bacteria....
Summary Hereditary hearing impairment is the most genetically heterogeneous trait known in humans. So far, 50 published autosomal recessive non‐syndromic (ARNSHI) loci have been mapped, and 23 ARNSHI genes identified. Here, we report mapping of a novel locus, DFNB63 , to chromosome 11q13.3‐q13.4 large consanguineous Tunisian family. A maximum LOD score 5.33 was obtained with microsatellite markers D11S916 D11S4207. Haplotype analysis defined 5.55 Mb critical region between D11S4136 D11S4081....
AbstractIn order to avoid false and quantitatively imprecise responses the stimulating electrode must be directly placed on round window membrane. That necessitates a transmeatal approach removing eardrum, which is commonly achieved under local anesthesia. The positive response subjectively easy identify; it may obectively registered by means of brain stem evoked responses; this registration indispensable in case children who need general This signifies that some cochlear nerve fibers are...
