Pharmaceutical Vehicles
In the field of pharmaceuticals, the term "pharmaceutical vehicles" is not widely recognized or consistently defined. However, it can be interpreted as a delivery system or vehicle that transports a therapeutic agent (drug) to its intended site of action within the body. This concept is often referred to as a drug delivery system.
Positronemissionstomografi
Positronemissionstomografi (PET) är en typ av bilddiagnostisk undersökningsmetod som används inom medicinen för att studera olika funktioner i kroppen, till exempel metabolism, blodflöde och receptoraktivitet. Metoden bygger på att man injicerar en patient med en liten mängd radioaktivt markert ämne (radioligand), som accumulerar i de vävnader eller organ som man vill undersöka.
Otoakustiska emissioner, spontana
Spontaneous otoacoustic emissions (SOAEs) are low-level sounds that originate from the inner ear (cochlea) and can be measured in the ear canal without external stimulation. They result from the natural motion of the hair cells within the cochlea and typically occur in the frequency range of 0.5 to 6 kHz. The presence and characteristics of SOAEs can provide valuable information about cochlear function and may be used in hearing assessments, particularly for early detection of cochlear damage or dysfunction.
