Wheat is one of the essential crops for the human and animal nutrition, however, contamination with aflatoxigenic fungi, due to the improper storage conditions and high humidity, was the main global threats. So, preventing the growth of aflatoxigenic fungi in stored wheat grains, by using different essential oils was the main objective of this work. Aspergillus flavus EFBL-MU12 PP087400, EFBL-MU23 PP087401 and EFBL-MU36 PP087403 isolates were the most potent aflatoxins producers inhabiting wheat grains.

Biodiesel is a sustainable, and renewable alternative to fossil fuels that can be produced from various biological sources with the aid of lipases. This study developed a simple and novel fungal system for lipase biosynthesis to be used for catalyzing the oily residuals into biodiesel, employing the artificial neural network (ANN), and semi-solid-state fermentation (SSSF). was selected among agro-industrial oily residuals as a substrate for lipase biosynthesis by MH47297.

Fungal producing potency of camptothecin (CPT) raise the hope for their usage to be a platform for industrial production of CPT, nevertheless, attenuation of their productivity of CPT with the subculturing and preservation is the challenge. So, screening for novel endophytic fungal isolates with a reliable CPT-biosynthetic stability was the objective. Among the isolated endophytic fungi from the tested medicinal plants, Aspergillus terreus OQ642314.

Background: Children with cleft palate are more liable to have obstructive sleep apnea than children with normal palate due to narrow airways. Tonsillar hypertrophy is a common cause of pediatric obstructive sleep apnea; hence, it is not surprising to be encountered during cleft palate repair. The aim of this study was to evaluate the feasibility of tonsillectomy and Furlow palatoplasty performed as a 1-stage operation in patients presenting with submucous cleft palate (SMCP) and tonsillar hypertrophy.

Treatment of diabetic foot ulcer (DFU) is of great challenge as it is shown to be infected by multidrug resistant bacteria (MDR bacteria). Sixty four bacterial isolates were isolated from DFU cases; antibiotic susceptibility tests were carried out for all of them. One bacterial isolate (number 11) was shown to resist the action of 8 out of 12 antibiotics used and was identified by both a Vitek-2 system and 16S rRNA fingerprints as belonging to and was designated LC587231 ().

Encountering a nasopharyngeal polyp in a patient with submucous cleft palate (SMCP) is a difficult problem, as the lesion could support the weak palate. Removal of this lesion may unmask the SMCP with consequent worsening of speech nasality. Nasal septal polyp protruding to the nasopharynx in a patient with SMCP has not been reported before in the literature.

The present study investigated the insecticidal activity of the different organic extracts from the entomopathogenic fungi, Cladosporium cladosporioides, Metarhizium anisopliae, Purpureocillium lilacinum, and Trichoderma longibrachiatum towards cotton aphid, Aphis gossypii. The methanol extracts from the mycelia and spores of C. cladosporioides and P.

Phytochemical study of the aerial part of L. led to the isolation of nine compounds. The structure of 1β,2α,3β,19α,23-pentahydroxy-urs-12-en-28-oic acid () was revised and confirmation of the stereochemical configuration of the hydroxyl groups was established using NOESY and selective decoupling experiments.

Thermo-optical switches are of particular significance in communications networks where increasingly high switching speeds are required. Phase change materials (PCMs), in particular those based on paraffin wax, provide wealth of exciting applications with unusual thermally-induced switching properties, only limited by paraffin's rather low thermal conductivity. In this paper, the use of different carbon fillers as thermal conductivity enhancers for paraffin has been investigated, and a novel structure based on spot of paraffin wax as a thermo-optic switch is presented.

Objective: Rarely the tonsillar pillars and the soft palate became adherent to the posterior nasopharyngeal wall by strong fibrous tissue due to excessive dissection and cauterization during surgery leading to nasopharyngeal stenosis. Therefore, many treatment modalities are being tried to cure this problem. The aim of this study is to explore our results of modifying the basic technique to accommodate those patients with combined nasopharyngeal stenosis and tonsillar pillars adhesions in one stage.

Fluorescence enhancement monitoring of pyrromethene laser dyes using their complexation with Ag nanoparticles (Ag NPs) was studied. The size of the prepared Ag NPs was determined by transmission electron spectroscopy and UV/Vis absorption spectroscopy. Mie theory was also used to confirm the size of NPs theoretically.
