Removal of bromophenol blue from polluted water using a novel azo-functionalized magnetic nano-adsorbent.

Water pollution from organic dyes poses a serious danger to the environment. In the present work, we report a novel adsorbent (ADFS) based on azo-dye-functionalized superparamagnetic iron oxide nanoparticles (SPIONs) for the removal of the anionic dye bromophenol blue (BPB) from contaminated water. The fabricated SPIONs, azo dye, and ADFS adsorbent were characterized with FTIR and UV-vis absorption spectroscopy, HNMR spectroscopy, mass spectrometry, SEM imaging, dynamic light scattering (DLS), zeta potential measurements, vibrating sample magnetometry, thermogravimetric analysis, differential thermal analysis, and X-ray diffraction analysis.

Assessment of knowledge and practices of exclusive breastfeeding among rural women during the COVID-19 pandemic in Egypt: a cross sectional study.

Background: Worldwide exclusive breastfeeding is still recommended as a successful strategy even during the COVID -19 pandemic to lower infant morbidity and mortality. This study aimed to assess the knowledge and practices of exclusive breastfeeding among rural women during the COVID-19 pandemic.

Methods: A descriptive cross-sectional study was conducted at EL-Morabeen Family Medicine Center in rural Damietta, Egypt among 178 lactating women who were chosen by using the purposive sampling technique.

Azo-functionalized superparamagnetic FeO nanoparticles: an efficient adsorbent for the removal of bromocresol green from contaminated water.

Water contamination is regarded as one of the world's worst tragedies owing to the continual depletion of water resources suitable for drinking and agriculture. Researchers have recently been interested in developing novel and more effective adsorbents for wastewater purification. We report herein a magnetic adsorbent nanomaterial for the removal of the anionic dye bromocresol green (BCG) from wastewater.

Matrix-dispersed magnetic molecularly-imprinted polyaniline for the effective removal of chlorpyrifos pesticide from contaminated water.

We report a new adsorbent nanocomposite material based on matrix-dispersed superparamagnetic iron oxide nanoparticles (SPIONs) in molecularly-imprinted polyaniline for the removal of chlorpyrifos (CPF), a hazardous organophosphate pesticide, from water. The synthesized magnetic molecularly-imprinted polymer (MMIP) was characterized by FTIR spectroscopy, XRD, magnetic susceptibility, DLS, zeta potential measurement, SEM and high-resolution TEM imaging. The average size of the naked SPIONs ranges from 15 to 30 nm according to the high-resolution TEM analysis.

Evaluation of Human Wharton's Jelly-Derived Mesenchymal Stem Cells Conditioning Medium (hWJ-MSCs-CM) or Scorpion Venom Breast Cancer Cell Line In Vitro.

Purpose: The present study aimed to evaluate the anticancer potential of Egyptian scorpion Leiurus quinquestriatus venom (ScV) or human Wharton's jelly-derived mesenchymal stem cells conditioning medium (hWJ-MSCs-CM)/CM against breast cancer (MCF-7) cell line as an alternative effective cancer biotherapy.

Methods: Venom (ScV) toxicity was performed recording concentration-dependent viability % and ScV IC value was in the order of 100 μg/ml. MCF-7 were treated with hWJ-MSCs-CM used as (25%, 50%, and 75% ml) or the IC of ScV.
