Periodicity in $Na^+$ channel properties alters excitability of a model neuron (2007)

Majumdar, Sriparna, Sikdar, Sujit K

The voltage gated Na channels play vital role in action potential waveform shaping and propagation. We have shown earlier that the duration and amplitude of a prolonged depolarization alter all the...

Small-world network topology of hippocampal neuronal network is lost, in an in vitro glutamate injury model of epilepsy (2007)

Srinivas, Kalyan V, Jain, Rishabh, Saurav, Subit, Sikdar, Sujit K

Neuronal network topologies and connectivity patterns were explored in control and glutamate-injured hippocampal neuronal networks, cultured on planar multielectrode arrays. Spontaneous activity was...

Overexpression, purification, and pharmacological activity of a biosynthetically derived conopeptide (2005)

Kumar, Ganesan Senthil, Ramasamy, Palanisamy, Sikdar, Sujit K, Sarma, Siddhartha P

A high yielding fusion protein system based on the protein cytochrome $b_{5}$ has been used for the production of novel 13-residue acyclic conopeptide. This peptide, Mo1659, can be liberated from the...

Induction of pseudo-periodic oscillation in voltage-gated sodium channel properties is dependent on the duration of prolonged depolarization (2004)

Majumdar, Sriparna, Foster, Grant, Sikdar, Sujit K

The neuronal voltage-gated sodium channels play a vital role in the action potential waveform shaping and propagation. Here, we report the effects of prolonged depolarization (1–160 s) on the...

A novel 13 residue acyclic peptide from the marine snail, Conus monile, targets potassium channels (2004)

Sudarslal, Sadasivannair, Singaravadivelan, Govindaswamy, Ramasamy, Palanisamy, Ananda, Kuppanna, Sarma, Siddhartha P, Sikdar, Sujit K, ...

A novel 13-residue peptide Mo1659 has been isolated from the venom of a vermivorous cone snail, Conus monile. HPLC fractions of the venom extract yielded an intense UV absorbing fraction with a mass...

Modeling excess retrieval in rat melanotroph membrane capacitance records.

Poberaj, Igor, Rupnik, Marjan, Kreft, Marko, Sikdar, Sujit K, Zorec, Robert

We have used the patch-clamp technique to monitor changes in membrane capacitance (C(m)) elicited by fast and spatially homogeneous rises in cytosolic calcium concentration ([Ca(2+)](i)) using flash...

Modulation of the unitary exocytic event amplitude by cAMP in rat melanotrophs

Sikdar, Sujit K, Kreft, Marko, Zorec, Robert

Secretory responses were measured in single rat pituitary melanotrophs as the relative increase in membrane capacitance (Cm) 8 min after the start of dialysis with solutions containing 0.45 μm Ca2+....
