Selective extraction and enrichment of 5-hydroymethylfurfural from honey, molasses, jam and vinegar samples prior to sensitive determination by micro-volume UV-vis spectrophotometry
(CADEMIC PRESS INC ELSEVIER SCIENCE525 B ST, STE 1900, SAN DIEGO, CA 92101-4495, 2021)
In this study, a new method was developed for the extraction/enrichment of 5-hydroxymethylfurfural (5-HMF) from sample matrix prior to analysis. The method is based on the selective formation of the imine adduct and ionpair ...
Eco-friendly trace analysis of silver in beer/wine samples using a new co-polymeric nanocomposite based-ultrasound assisted-cloud point extraction combined with spectrophotometry
(ACADEMIC PRESS INC ELSEVIER SCIENCE525 B ST, STE 1900, SAN DIEGO, CA 92101-4495, 2021)
In this study, a new magnetic nanocomposite based on the tris(2-hydroxymethyl)aminomethane-modified poly (styrene-co-N-maleimide) copolymer and Fe3O4 nanoparticles were prepared as a new micellar interface for preconcentration ...
Phylogenomic Analyses of the Tenthredinoidea Support Familial Rank of Athaliidae (Insecta, Tenthredinoidea)
(21.09.2022)
The systematic status of the genus Athalia and related genera is a perennial controversy
in sawfly taxonomy. Several authors have hypothesized that the placement of Athalia within the
Tenthredinidae is artificial, but ...
A comprehensive and current review on the role of flavonoids in lung cancer–Experimental and theoretical approaches
(17 Şubat )
Background: It is well-known that flavonoids, which can be easily obtained from many fruits and vegetables are widely preferred in the treatment of some important diseases. Some researchers noted that these chemical compounds ...

(cancer nanotechnology, 2022)
AbstractNano-biotechnology-based clinical applications to cure health-related issues have gained huge attention among the scientific community and hold great promise to limit cancer metastasis. In this study, green-derived ...
Pharmacological effects and therapeutic potential of natural compounds in neuropsychiatric disorders: An update
(Frontiers Media SA, 2022)
Neuropsychiatric diseases are a group of disorders that cause significant morbidity and disability. The symptoms of psychiatric disorders include anxiety, depression, eating disorders, autism spectrum disorders (ASD), ...
The effects of thymoquinone on pancreatic cancer: Evidence from preclinical studies
(Elsevier BV, 2022)
Thymoquinone (TQ) is a secondary metabolite found in abundance in very few plant species including Nigella
sativa L., Monarda fistulosa L., Thymus vulgaris L. and Satureja montana L. Preclinical pharmacological studies ...
The role of Tumour Necrosis Factor in neuroinflammation associated with Parkinson's disease and targeted therapies
(neurochemistry international, 2022)
Neurodegenerative disorders Parkinson’s disease is a progressive neurodegenerative disorder associated with
neuroinflammatory responses that lead to the neurodegeneration of the dopaminergic neurons. These neuroinflammatory ...
A magnetic nanocomposite based on amine‑functionalized pH‑sensitive functional poly(styrene‑co‑maleic anhydride) copolymer for selective extraction, pre‑concentration and determination of sub‑trace Ag+ and Cu2+ ions from edible vegetable oils by a combination of spectrophotometry and ultrasound‑assisted cloud point extraction
(2022)
In this study, a new magnetic nanocomposite based on amine-functionalized pH-sensitive poly(styrene-co-maleic anhydride)
copolymer derived from the tris(2-hydroxymethyl)aminomethane and Fe3O4
nanoparticles was designed, ...
pH-controlled charge transfer sensitive 2-aminobenzimidazole modified poly(styrene-co-maleic anhydride) copolymer for selective extraction, pre-concentration and determination of trace Hg2+ and CH3Hg+ in vinegar by combination of ultrasound assisted-cloud point extraction with UV–VIS spectrophotometry
(Elsevier, 8 July 202)
In this study, a separation/pre-concentration procedure, ultrasound assisted-cloud point extraction with modified
2-aminobenzimidazole (2-ABzI), was developed for the extraction of trace Hg2+ and CH3Hg+ and from
vinegar ...
