Incidence of refractive surprise after phacoemulsification in patients of cataract with primary pterygium.

Purpose: The purpose of this study was to find the incidence of refractive surprise in patients of cataract with primary pterygium and compare it with patients of cataract without pterygium after phacoemulsification surgery.

Methods: The present observational study included 30 patients who had cataract with pterygium and 30 patients of cataract without pterygium. A detailed ophthalmic examination was done in all the cases.

Transcription control pathways decode patterned synaptic inputs into diverse mRNA expression profiles.

Synaptic plasticity requires transcription and translation to establish long-term changes that form the basis for long term memory. Diverse stimuli, such as synaptic activity and growth factors, trigger synthesis of mRNA to regulate changes at the synapse. The palette of possible mRNAs is vast, and a key question is how the cell selects which mRNAs to synthesize.

Nature of molecular rotation in supercooled glycerol under nanoconfinement.

The dynamics of glass-forming liquids under nanoconfinement is key to understanding a variety of phenomena in nature and modern technology. We report a (13)C NMR spectroscopic study that directly demonstrates that alpha-relaxation in bulk glycerol involves an isotropic rotational jump of the constituent molecules. The activation energy of this motion is approximately 78 kJ mol(-1) in the bulk, which abruptly changes to a low value of approximately 27.

Signaling logic of activity-triggered dendritic protein synthesis: an mTOR gate but not a feedback switch.

Changes in synaptic efficacy are believed to form the cellular basis for memory. Protein synthesis in dendrites is needed to consolidate long-term synaptic changes. Many signals converge to regulate dendritic protein synthesis, including synaptic and cellular activity, and growth factors.
