PEG stearates are extensively used as emulsifiers in many lipid-based formulations. However, the scheme of the principles of the lipid-surfactant polymer interactions are still poorly understood and need more studies. A new phase diagram of a lecithin/PEG 40 monostearate/water system at 30 °C is reported. First, we have characterized the binary PEG 40 monostearate/water system by the determinat...

In an era moving towards digital health, 3D printing has successfully proven its applicability in providing personalised medicine through a technology-based approach. Among the different techniques, direct extrusion been demonstrated as promising approach for on demand manufacturing of solid dosage forms. However, it usually requires use elevated temperatures and/or incorporation evaporable sol...

objective(s): the aim of the present study was to prepare, characterize, and evaluate solid lipid nanoparticles (slns) containing zataria multiflora essential oil (zeo). materials and methods: in this study, z. multiflora essential oil-loaded solid lipid nanoparticles (ze-slns) were prepared to improve its efficiency in controlling some fungal pathogens. slns containing z. multiflora essential ...

to the degree of coronary narrowing, 47 consecutive chest pain patients were studied without premedication by analysing selective coronary angiograms before and after glyceryl trinitrate. Proximal coronary diameters were measured in superimposed frames with callipers. Lumen diameter increased after glyceryl trinitrate 15 ± 2 per cent in the left main, 18 ± 2 per cent in the left anterior descen...

Cerebral malaria (CM) is associated with low nitric oxide (NO) bioavailability, cerebrovascular constriction, occlusion, and hypoperfusion. Administration of exogenous NO partially prevents the neurological syndrome and associated vascular pathology in an experimental CM (ECM) mouse model. In this study, we evaluated the effects of transdermal glyceryl trinitrate in preventing ECM and, in combi...

Background—Nitric oxide is a major neurotransmitter in non-adrenergic, noncholinergic (NANC) pathways. NANC inhibitory innervation has been shown in human gall bladder muscle in vitro; the role of nitric oxide in human gall bladder emptying however is undefined. Aims—To study the eVect of glyceryl trinitrate, a nitric oxide donor, on gall bladder emptying in healthy subjects using a randomised,...

Intratumoral and intralesional administration of anticancer drugs in gels and implantable formulations is gaining much importance on account of its advantage of site-specific delivery with highly dependable freedom from unwanted side effects. Nanolipid carriers (NLC) are the preferred vehicle due to their improved properties particularly drug loading. In the present investigation, glyceryl mono...

Changes in left ventricular size may be of importance in the development of angina and in its amelioration by glyceryl trinitrate, but left ventricular dimensions have not been measured during exercise in the upright position, the circumstance in which angina most often occurs. To assess changes in left ventricular end-systolic and end-diastolic dimensions, echocardiograms were obtained from 5 ...
