Objectives Use of a reliable method to determine the degree of skeletal development of the mid-palatal suture is important in the choice of treatment between orthopedic maxillary expansion and surgical expansion in adolescents and young adults. The aim of this study was to review the new methods for evaluation of mid-palatal suture maturation. Methods Electronic search was conducted in PubMed ...

results the hemostasis time for the ferric chloride concentration group was significantly less than for the control group (p < 0.001). materials and methods in this animal model study, 60 male wistar rats were used. an incision, 2 cm long and 0.5 cm deep was made on rat skin and the hemostasis time was recorded using ferric chloride at different concentrations (5%, 10%, 15%, 25%, and 50%) and t...

introduction: this study was carried out to compare the effect of different suture removal time on surgical wound healing. materials and methods: twenty-one male albino rabbits were used. under general and local anesthesia a moucoperiosteal rectangular flap was raised in each animal and then repositioned and sutured. the animals were randomly divided into three experimental groups of seven anim...

A readily releasable pool of quanta, tentatively identified with docked synaptic vesicles, has been defined by analysis of the neurotransmitter release caused by application of hypertonic solutions. The goal of this work is to determine the relationship of this functionally defined readily releasable pool to the one drawn upon by action potential-evoked release. We find that hypertonic solution...

background:  few clinical trials have studied the functional and cosmetic outcomes of different closure tech- niques of surgical incisions. skin wound and incision closure methods may influence the healing process and cos- metic outcome. the present study aims at comparing three different suture techniques of skin closure. methods: in a clinical trial, sixty patients with anterior cruciate liga...

Synaptic vesicles are recycled locally within presynaptic specializations. We examined how vesicles are reused after endocytosis, using transgenic mice expressing the genetically encoded fluorescent indicator synaptopHluorin in subsets of neurons. At both excitatory and inhibitory synapses in cultured hippocampal neurons, newly endocytosed vesicles did not preferentially enter the releasable po...

We have used flash photolysis of caged Ca2+ and membrane capacitance measurements to probe exocytosis in chromaffin cells at low concentrations of intracellular Ca2+ ([Ca2+]i) (<10 microM). We observed a small pool of granules that is more sensitive to [Ca2+]i than the previously described "readily releasable pool." Upon activation of PKC, this "highly Ca2+-sensitive pool" is enhanced in size t...

Synaptotagmin I is a synaptic vesicle-associated protein essential for synchronous neurotransmission. We investigated its impact on the intracellular Ca(2+)-dependence of large dense-core vesicle (LDCV) exocytosis by combining Ca(2+)-uncaging and membrane capacitance measurements in adrenal slices from mouse synaptotagmin I null mutants. Synaptotagmin I-deficient chromaffin cells displayed prol...
