Generic approach in a gradient elution HPLC method development that enables troubleshooting free method transfer
(Elsevier B.V., 2022)
Nowadays, method development is strongly focused on reducing time needed for method development and execution. This subject specially concerns gradient elution methods regarding the usual need for trouble shooting assistance ...
Ring closing metathesis/fragmentation route to (Z)-configured medium ring cycloalkenes. Total synthesis of (+/-)-periplanone C
(Amer Chemical Soc, Washington, 2006)
The combination of ring closing metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under anionic or radical conditions. The ...
Quantitative structure-retention relationship of selected imidazoline derivatives on alpha(1)-acid glycoprotein column
(Elsevier Science BV, Amsterdam, 2016)
The retention behaviour of 22 selected imidazoline drugs and derivatives was investigated on alpha(1)-acid glycoprotein (AGP) column using Sorensen phosphate buffer (pH 7.0) and 2-propanol as organic modifier. Quantitative ...
Tailored porosity development in carbons via Zn2+ monodispersion: Fitting supercapacitors
(Elsevier B.V., 2022)
Here, we propose a novel, electrochemical preparation of in situ N-doped alginate-based carbon precursors with monodispersed zinc ions. Obtained carbons were evaluated by spectroscopic (FTIR, Raman and XPS), textural (N2 ...
pH-sensitive microparticles for oral drug delivery based on alginate/oligochitosan/Eudragit (R) L100-55 "sandwich" polyelectrolyte complex
(Elsevier Science BV, Amsterdam, 2013)
The primary objective of this study was to investigate the influence of the oligochitosan-Eudragit (R) L100-55 polyelectrolyte complex (OCH-EL PEC) on the pH-sensitivity of Eudragit (R) L100-55-treated alginate-oligochitosan ...
Supercritical fluid impregnation of microcrystalline cellulose derived from the agricultural waste with ibuprofen
(Elsevier B.V., 2021)
The present study was aimed to investigate the feasibility of loading microcrystalline cellulose derived from the agricultural waste with poorly water-soluble drug by using supercritical carbon dioxide as impregnation ...
Acth-induced model of depression resistant to tricyclic antidepressants: Neuroendocrine and behavioral changes and influence of long-term magnesium administration
(Academic Press Inc Elsevier Science, San Diego, 2018)
Magnesium (Mg), is not only a modulator of the glutamatergic NMDA receptors' affinity, it also prevents HPA axis hyperactivity, thus possibly being implicated in neurobiological features of mood disorders. Further uncovering ...
What role does carbonized tannic acid play in energy storage composites?
(Elsevier Ltd, 2022)
Transformation of tannic acid (TA), a cheap, abundant and environmentally friendly (by)product, upon carbonization at various temperatures was examined as it is extensively being used in energy storing devices. In addition ...
Poly(lactide-co-glycolide)/silver nanoparticles: Synthesis, characterization, antimicrobial activity, cytotoxicity assessment and ROS-inducing potential
(Elsevier Sci Ltd, Oxford, 2012)
Silver nanoparticles (AgNps) were prepared by modified chemical reduction with poly (alpha, gamma, L-glutamic acid) (PGA) as capping agent. These Ag/PGA nanoparticles (AgNpPGAs) were highly stable over long periods of time ...
Comparative efficacy evaluation of different penetration enhancement strategies for dermal delivery of poorly soluble drugs – A case with sertaconazole nitrate
(Elsevier B.V., 2021)
The aim of this study was to compare the efficacy of different approaches for enhancement of dermal availability of the highly lipophilic antifungal model drug – sertaconazole nitrate (SN). For this purpose, a physical ...
