Sitting position awake craniostomy with drainage for chronic subdural hematoma: a viable alternative?
(Vojnosanitetski Pregled, 2021)
Background/Aim. Chronic subdural hematoma (CSDH) is one of the most frequent neurosurgical conditions with an overall incidence ranging from 1.72 to 20.6 per 100,000 persons per year. The surgical procedure for CSDH is ...
Hydroxyapatite/nifuroxazide conjugate: Characterization, drug release and antimicrobial activity / Хидроксиапатит/нифуроксазид конјугат: карактеризација, отпуштање лека и антимикробна активност
(Serbian Chemical Society, 2021)
Synthetic hydroxyapatite (Ca-10(PO4)(6)(OH)(2), HAp) is very similar to the inorganic part of the bones and teeth of mammals. It is a well-known biomaterial with good biocompatibility, osteoconductivity and bioactivity. ...
A comparative study of chromatographic lipophilicity and bioactivity parameters of selected spirohydantoins
(Taylor & Francis Inc, Philadelphia, 2020)
In this study, lipophilicity of 21 cycloalkylspiro-5-hidantoins was assessed. The overall goal of lipophilicity evaluation is preliminary investigation which should result in a decrease of the traditionally high attrition ...
