The physiochemical aspects of the matrix play an important role in deciding loading sulfur cathodes.
Understanding the complexity of dissolved organic matter (DOM) in stormwater has drawn a lot of interest, since DOM from stormwater causes not only environmental impacts, but also worsens downstream aquatic quality associated with water supply and treatability. This study introduced and employed high-performance size exclusion chromatography (HPSEC) coupled with an ultraviolet-visible (UV-vis) ...
abstractmedication errors are commonly encountered in hospital setting. intravenous medications pose particular risks because of their greater complexity and the multiple steps required in their preparation, administration and monitoring. we aimed to determine the rate of errors during preparation and administration phase of intravenous medications and the correlation of these errors with the d...
Introduction: Pharmacological studies revealed anti-inflammatory and analgesic properties of chamomile and its main components. The aim of the present study is preparing and characterizing a niosomal gel containing chamomile extract. Methods: Nisomes containing 2% and 5% of the extract were prepared using film hydration method. Non-ionic surfactants including sorbitan esters (spans) and ethoxy...
Biological apatite is an inorganic calcium phosphate salt in apatite form and nano size with a biological derivation. It is also the main inorganic component of biological hard tissues such as bones and teeth of vertebrates. Consequently, biological apatite has a wide application in dentistry and orthopedics by using as dental fillers and bone substitutes for bone reconstruction and regeneratio...
We report the effects of oxidative stress generated by low-intensity u.v. irradiation (366 and 254 nm), dialysis against ascorbate and isolated stimulated neutrophils on some physicochemical properties of caeruloplasmin. Low-intensity u.v. irradiation resulted in a loss of ferroxidase activity and 610 nm absorption, changes previously reported to occur during storage and manipulation of caerulo...
