NEUROTROPHIC EFFECTS OF ETIFOXINE
Higher anxiety results in the decreased levels of various neurotrophic factors and enkephalins and in impaired production of proinflammatory cytokines. The anxiolytic etifoxine is used to treat anxiety states and adjustment disorders. Etifoxine modulates

Prediction of Peptide Conformation by the Multicanonical Algorithm [PDF]
We test the effectiveness of the multicanonical algorithm for the tertiary structure prediction of peptides and proteins. As a simple example we study Met-enkephalin. The lowest-energy conformation obtained agrees with that determined by other methods such as Monte Carlo simulated annealing.

Capillary HPLC Separation of Selected Neuropeptides [PDF]
Neuropeptides play a pivotal role in brain and peripheral nervous system function. As high performance liquid chromatography (HPLC) becomes the central tool in the separation and characterization of peptide and protein samples, its selectivity ...

Modulation of Neurally Mediated Vasodepression and Bradycardia by Electroacupuncture through Opioids in Nucleus Tractus Solitarius. [PDF]
Stimulation of vagal afferent endings with intravenous phenylbiguanide (PBG) causes both bradycardia and vasodepression, simulating neurally mediated syncope.

Molecular Aspect of Annelid Neuroendocrine system
Hormonal processes along with enzymatic processing similar to that found in vertebrates occur in annelids. Amino acid sequence determination of annelids precursor gene products reveals the presence of the respective peptides that exhibit high sequence ...

Numerical Comparisons of Three Recently Proposed Algorithms in the Protein Folding Problem [PDF]
We compare numerically the effectiveness of three recently proposed algorithms, multicanonical simulations, simulations in a 1/k-ensemble, and simulated tempering for the protein folding problem. For this we perform simulations with high statistics for one of the simplest peptides, Met-enkephalin.

Immune and Opioid system interaction in pain modulation [PDF]
Background: Inflammatory pain is caused by direct stimulation of nociceptors with the release of inflammatory mediators. Several studies about the roles of immune and opioid systems in the pain process have suggested that their crosstalk may have ...

Resolution exchange simulation with incremental coarsening [PDF]
We previously developed an algorithm, called resolution exchange, which improves canonical sampling of atomic resolution models by swapping conformations between high- and low-resolution simulations[1]. Here, we demonstrate a generally applicable incremental coarsening procedure and apply the algorithm to a larger peptide, met-enkephalin.

Afferent Neuronal Control of Type-I Gonadotropin Releasing Hormone Neurons in the Human. [PDF]
Understanding the regulation of the human menstrual cycle represents an important ultimate challenge of reproductive neuroendocrine research. However, direct translation of information from laboratory animal experiments to the human is often complicated ...
