Compensatory endocytosis of exocytosed membrane and recycling of synaptic vesicle components is essential for sustained synaptic transmission at nerve terminals. At the ribbon-type synapse of retinal bipolar cells, manipulations expected to inhibit the interactions of the clathrin adaptor protein complex (AP2) affect only the slow phase of endocytosis (τ = 10-15 s), leading to the conclusion th...
results the results showed that the fiber diameter and the amount of loratadine affected the drug release and the disappearance time of nanofibers. the smaller the fiber diameter and drug amount, the faster the solubility and the release time of nanofibers. conclusions it was concluded that electrospinning can be a suitable method for preparing fast-dissolving loratadine nanofibers. materials a...
OBJECTIVES The objective of this study was to correlate electrocardiographic (ECG) PR interval changes during normal sinus rhythm with recent observations regarding the anatomy and physiology of the dual, slow and fast atrioventricular (AV) pathways. BACKGROUND The least common manifestation of dual AV conduction is an abrupt PR interval change in the setting of sinus rhythm. Whereas isolated...
Primordial Germ Cells (PGCs) are unipotent precursors of the gametes. PGCs can give rise to a type of pluripotent stem cells in vitro that are called embryonic germ (EG) cells. PGCs can also acquire such pluripotency in vivo and generate teratomas. Under specific culture conditions, PGCs can be reprogrammed to embryonic germ cells which are capable of expression of key pluripotency marker...
one of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. the four pattern recognition molecules that have been identified till now are mannose binding lectin (mbl), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. mbl ...
BACKGROUND Recent evidence suggests that atrioventricular junctional reentrant tachycardia (AVJRT) uses a reentrant circuit that involves the atrioventricular (AV) node, the atrionodal connections, and perinodal atrial tissue. Electrogram morphology has been used to target the delivery of radiofrequency energy to the site of the "slow pathway," a component of this reentrant circuit. The aim of ...
