Here we describe recent appliions and technical advancements of functional multineuron calcium imaging (fMCI), which monitors the firing activity of more than a thousand neurons through their somatic Ca^<2+> signals. fMCI is used for analysis of various neural circuits under normal and pathological conditions. In vitro fMCI is made more sophistied by
Abstract Bone substitutes, like calcium phosphate, are implemented more frequently in orthopaedic surgery to reconstruct critical size defects, since autograft often results in donor site morbidity and allograft can transmit diseases. A novel bone cement, based on β-tricalcium phosphate, polyethylene glycol, and trisodium citrate, was developed to allow the rapid manufacturing of scaffolds

The technique is similar to previously published protocols for in vivo two-photon calcium imaging with synthetic calcium dyes (Stosiek et al. Proc Natl Acad Sci U S A 100:7319–7324, 2003). Hence, only minor changes of a generic two-photon setup and some adaptations of …
Fluorescence imaging of individual cells and tissue samples Cell sorting and cloning The Facility is also equipped with a laser-based scanning confocal microscope (Leica TCS SP8). This instrument can be used to: Conduct advanced imaging of tissue sections
Calcium imaging For time‐lapse calcium imaging, cells were incubated at 37 C with 5 µ m Fluo4 AM (Molecular Probes) in the absence or presence of test molecules. After 30 min, cells were washed and placed in NaCl/P i for 30 min.
ScreenWorks Pro 2 software analysis, powered by pCLAMP 11, gives you the unique ability to characterize calcium oscillation data in one software program. Compounds can be flagged that cause waveform irregularities that may indie hazards for arrhythmia, seizures, or other toxicity effects quickly and without having to export data.
Cells that responded to JYs also released less Ca 2+ when treated with TG than cells in the same experiment that did not respond to targets (data not shown). These results confirm that contact with JY targets releases Ca 2+ from the TG-sensitive Ca 2+ stores that control CCE, which is consistent with the idea that CCE participates in the response to target cells.
EARLY STUDIES ON PLANT CALCIUM Ca 2+ is an essential element; however, its role is elusive. When examining total Ca 2+ in plants, the concentration is quite large (mM), but its requirement is that of a micronutrient (μM). Ca 2+ is not usually limiting in field conditions, still there are several defects that can be associated with low levels of this ion, including poor root development, leaf
Chromogranin A (CgA) may be critical for secretory granule biogenesis in sympathoadrenal cells. Cells were washed with calcium secretion buffer (150 m m NaCl, 5 m m KCl, 2m m CaCl 2, and 10 m m HEPES (pH 7.4)) and subsequently exposed to calcium
For calcium-imaging experiments 7–15 μM Fura red/AM (Molecular Probes, Eugene, OR) was loaded into cells for 30–40 min. Cells were then washed and incubated in fresh imaging medium for 15 min before acquisition.

Pairing two-photon stimulation technology with two-photon calcium imaging allowed the researchers to document how individual cells responded to light stimulation. Though previous studies have targeted and recorded individual cells none have demonstrated that a bundle of neurons could be fired off together to imprint what they call a “neuronal microcircuit” in a live animal’s brain.
29/10/2008· The soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex, comprised of SNAP-25, syntaxin 1A, and VAMP-2, has been shown to be responsible for action potential (AP)-dependent, calcium-triggered release of several neurotransmitters. However, this basic fusogenic protein complex may be further specialized to suit the requirements for different …
