The aim of the present work is to efficiently synthesize promising novel antitumor and antimicrobial active heterocyclic compounds from chalcones 1a and 1b as a precursor which contain naphthalene moiety and indole or piperonal moiety, respectively, using conventional, ultrasonic and microwave irradiation techniques. The best yields and purity were afforded with the microwave irradiation technique. Reaction of 1a and 1b with the appropriate reagent gave the corresponding pyrazolines 2a, 2b, pyrimidine-2-thioneses 3a, 3b, oxazepines 4a, 4b, diazepines 5a, 5b, triazolo-pyrimidines 6a, 6b, and pyrimidine-2-thiols 7a, 7b derivatives. Compounds 7a, 7b were used to produce 8a, 8b. Moreover, pyrimidine-2-thione 3a was used to synthesize pyrimidin2-ylthioacetic acid 9a, and 2-hydrazinylpyrido[2,3-d]pyrimidine derivative 10a which has been used as a functionalizing agent to produce compounds 11a-14a. The structural formulas of the synthesized compounds were confirmed by their spectral data; FT-IR, H NMR, C NMR and MS. Compounds 3a, 5a, 7a, 13a showed a very high activity as antitumor, whereas compounds 4a, 6a, and 13a showed high activity as antibacterial and antifungal agents.

In recent years, genetically modified (GM) crops aim to produce food and feed which has become part of the usual agriculture in many areas of the world. Whether GM food and feed have positive or negative impacts on humans or animals is still unclear. Therefore, an investigation of the effects of different diets containing genetically modified food (GMF) on insulin hormone, glucose, and lipid profile were carried out in the present study. Male and female Wister Albino rats70-80 g range body weight was used in the present study. Each sex was divided into 4 groups (n = 10 per group). Control group fed on the basal diet American Institute of Nutrition for Growth (AIN93 G) and three treated groups were given GM (corn, wheat, and rice) and water adlibitum for three months. The reason for choosing these foods is because they are the most basic foods consumed in our daily life (bread and rice). At the end of the experimental period results compared to the control group GM (corn, wheat, and rice) for both sexes showed a significant decrease in serum insulin and the significant increase in serum glucose. Also, significant increase in total cholesterol (TC) , triglycerides (TG), low density lipoprotein-cholesterol (LDL-C), very low density lipoproteins (VLDL), Risk ratio I and Risk ratio II. Yet, serum high density lipoproteins cholesterol (HDL-C) levels showed significant decrease in all groups. Body weight showed a significant increase in all groups of males and female rats.

Yeast cells are commonly used as powerful model system to study morphological phenotype and their processes. The study of morphogenesis of different modes of growth in yeast during biofilm development is an important issue. Cell progression is important tool to understand morphological transition and virulence in C. albicans. Biofilm formation and aspartic proteinase activity are two major important virulence factors associated with the pathogenicity of C. albicans. This study aimed to highlight the formation of biofilm, monitor the development of biofilm progression and estimate the activity of aspartic proteinase. Biofilm formation was assessed by Eliza plate and monitored at different pH values, different incubation time and different media. Biofilm development was visualized microscopically. Cell division and mitotic phases in yeast cells were studied and photographed. The production of aspartic proteinase was assessed by bovine serum albumin agar plates and evaluated at different pH values and different incubation time intervals. Results revealed that C. albicans was positive for biofilm formation and aspartic proteinase production. pH and different media had marked significant effect on biofilm formation. Additionally, the transition from simple yeast budding form to a complex filament structure was time dependent. Moreover, pH showed significant effect on aspartic proteinase activity.

DNA barcoding is a molecular genetics technique commonly applied for species identification based on the cytochrome c oxidase subunit I (COI) gene located on the mitochondrial DNA genome. Based on our analysis, the DNA barcodes were generated from 16 specimen of Coccinella (family Coccinellidae). All the samples were collected from diverse sites in Egypt and Libya. Morphological traits based on the number of dorsal spots, DNA extraction, PCR amplification of COI, sequencing, nucleotide BLAST, and phylogenetics analyses were used to classify the specimens. A phylogenetic tree was constructed using the maximum likelihood method, including 46 COI sequences (the study and NCBI sequences). Three Coccinella clusters were defined and classified as Coccinella septempunctata, Coccinella novemnotata, and Coccinella undecimpunctata each species clustered into a unique branch. DNA barcodes discriminated clearly against the analyzed species. This study validated the COI efficiency as a marker for DNA barcoding of insects (Coccinella, family Coccinellidae).

Multidrug-resistant (MDR) bacteria is a severe problem for universal public health which increases morbidity and mortality rate. These resistant bacteria lead to ineffective treatment of drugs resulting in the spreading and persistence of infections. So, the major target of this study is to estimate the competence of multidrug antibacterial agents against bacterial strains isolated from wound samples and then identify the most potent Multidrug-resistant (MDR) bacteria. Fifty wound swab specimens were gathered from various wounds and several patients from the Central Microbiology Laboratory of El-Demerdash Hospital, Cairo, Egypt. Eightynine bacterial isolates were isolated from fifty wound samples then cultured on different media and tested for their susceptibility to different thirty antibiotic discs using the agar disc diffusion method. After recording the results of the susceptibility test, the post potent resistant bacterial isolates recorded 3 bacterial isolates which resistant to 30 different antibiotic types. These resistant bacterial isolates were identified using morphological, biochemical, and molecular techniques. The results recorded that the post potent resistant bacterial isolates identified as Klebsiella oxytoca, Pseudomonas aeruginosa, and Escherichia coli. This study concluded that with the increase in the random use of antibiotic drugs resulted in the presence of multi-antibacterial resistant strains. There are bacterial strains that were isolated from wounds in patients at El-Demerdash Hospital, Egypt, and identified. They can resist about thirty different antibiotic discs. Abbreviation: Multiple antibiotic resistance (MAR).

In this study, we used the Agrobacterium tumefaciens–mediated transformation approach to transfer the activity of the cyanobacterial cyanase enzyme into the microalga, Chlamydomonas reinhardtii. In transgenic C. reinhardtii strains, the recombinant cyanase enzyme was proven to be active. In comparison to wild-type control, transgenic type demonstrated higher rates of ammonia release, reduced loss of pigmentation, and a lower percentage of growth retardation when varied amounts of cyanide (up to 200 ppm) were applied to the growth medium. Moreover, cyanase activity increases as concentration of cyanide increase especially in case of transgenic. The maximum activity was indicated in presence of 100 mg/l cyanide it reached eight folds more than wild activity at the same cyanide concentration. Results of this study provide an effective eco-friendly phytoremediation system for detoxification of cyanide using micro-alga compared to previously reported conventional system for removal of cyanide compounds, Also, some factors are taken in consideration like different pH, contact time and the transgenic type has been the priority for removal cyanide at wide range of pH with two folds more than wild type.

arley (Hordeum vulgare L.) is one of the founder crops of Old-World agriculture, it was one of the first domesticated cereals. It is also a model experimental system because of its short life cycle and morphological, physiological, and genetic characteristics. Barley is used for, in order of importance, animal feed, brewing malts and human food. Barley is found in widely varying environments globally. It has wide adaptation ability to different climatic conditions and various environments comprising drought and irrigated environments (Nevo, 1992; Gomez-Macpherson, 2001).
