Green fabrication of ZnO nanoparticles via spirulina platensis and its efficiency against biofilm forming pathogens.

Excessive consumption of antibiotics is considered one of the top public health threats, this necessitates the development of new compounds that can hamper the spread of infections. A facile green technology for the biosynthesis of Zinc oxide nanoparticles (ZnO NPs) using the methanol extract of Spirulina platensis as a reducing and stabilizing agent has been developed. A bunch of spectroscopic and microscopic investigations confirmed the biogenic generation of nano-scaled ZnO with a mean size of 19.

Psychiatric illness and pregnancy: A literature review.

Background: Women of reproductive age frequently suffer from psychiatric disorders. The risk of developing anxiety, bipolar, and depressive disorders is especially significant during the perinatal period.

Objectives: This article aims to identify and discuss the different psychiatric conditions that might affect pregnant women and update the mother's carers about the recent and updated bidirectional relationship between psychiatric disease and adverse pregnancy outcomes, As well as the most updates in diagnostic and management strategies.

Generation of green electricity from sludge using photo-stimulated bacterial consortium as a sustainable technology.

Microbial fuel cell (MFC) is a bio-electrical energy generator that uses respiring microbes to transform organic matter present in sludge into electrical energy. The primary goal of this work was to introduce a new approach to the green electricity generation technology. In this context a total of 6 bacterial isolates were recovered from sludge samples collected from El-Sheikh Zayed water purification plant, Egypt, and screened for their electrogenic potential.

Molecular modeling study of micro and nanocurcumin with in vitro and in vivo antibacterial validation.

Repurposing natural compounds as inhibitory targets to combat bacterial virulence is an important potential strategy to overcome resistance to traditional antibiotics, in the present study, the antibacterial activity of micro-curcumin and nano-sized curcumin was investigated against four predominant bacterial pathogens, namely, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis. Curcumin bactericidal susceptibility could be summarized as the order, P. aeruginosa > B.

Short-Term Biodegradation of Crude Petroleum Oil in Water by Photostimulated Strain S1N1.

Biodegradation is a sustainable green strategy that gives the opportunity for remediation of water contaminated with petroleum products. In this study, 12 bacterial isolates were recovered from River Nile, Egypt and screened for their potential to degrade a mixture of paraffinic petroleum crude oil. The most promising isolate was identified according to 16S rRNA sequencing as strain S1N1 (GenBank accession No.

Synthesis of a new class of antimicrobial agents incorporating the indolin-2-one moiety.

New furanone derivatives incorporating the indolin-2-one moiety 3 were prepared via the Perkin reaction of isatins 1 with aroylpropionic acids 2 under conventional conditions or microwave irradiation. A series of functionally heterocyclic derivatives (e.g.

Synthesis, characterization and in vitro antimicrobial evaluation of new compounds incorporating oxindole nucleus.

New compounds incorporating with the oxindole nucleus were synthesized via the reaction of substituted isatins [5-methyl-, 5-chloro- and 1-hydroxymethyl isatins] with different nucleophiles. The structures of the newly compounds were elucidated on the basis of FTIR, (1)H NMR, (13)CMR spectral data, GC/MS and chemical analysis. Investigation of antimicrobial activity of the new compounds was evaluated using broth dilution technique in terms of minimal inhibitory concentration (MIC) count against four pathogenic bacteria and two pathogenic fungi.
