Use of Spectacles after Cataract Surgery.

Purpose: The goal of this study was to investigate the use of spectacles in everyday life after bilateral cataract surgery with a preoperative refractive target of emmetropia in both eyes. In addition, we analyzed the total cost of spectacles and the patient's visual satisfaction at least 6 months after surgery.

Methods: Patients after bilateral cataract surgery with implantation of an aspheric monofocal IOL (Tecnis 1, Johnson & Johnson) with a preoperative refractive target of emmetropia in both eyes and a documented refractive outcome were included in this prospective observational study.

The memory gene KIBRA is a bidirectional regulator of synaptic and structural plasticity in the adult brain.

Memory formation is associated with activity-dependent changes in synaptic plasticity. The mechanisms underlying these processes are complex and involve multiple components. Recent work has implicated the protein KIBRA in human memory, but its molecular functions in memory processes remain not fully understood.

Identification of combinatorial patterns of post-translational modifications on individual histones in the mouse brain.

Post-translational modifications (PTMs) of proteins are biochemical processes required for cellular functions and signalling that occur in every sub-cellular compartment. Multiple protein PTMs exist, and are established by specific enzymes that can act in basal conditions and upon cellular activity. In the nucleus, histone proteins are subjected to numerous PTMs that together form a histone code that contributes to regulate transcriptional activity and gene expression.

Nigrostriatal overabundance of α-synuclein leads to decreased vesicle density and deficits in dopamine release that correlate with reduced motor activity.

α-Synuclein (α-syn) is a presynaptic protein present at most nerve terminals, but its function remains largely unknown. The familial forms of Parkinson's disease associated with multiplications of the α-syn gene locus indicate that overabundance of this protein might have a detrimental effect on dopaminergic transmission. To investigate this hypothesis, we use adeno-associated viral (AAV) vectors to overexpress human α-syn in the rat substantia nigra.

Epigenetics and the human brain: where nurture meets nature.

While our genetic code determines a great deal of who and what we are, it does not act alone. It depends heavily on the epigenome, an elaborate marking of the DNA that controls the genome's functions. Because it is sensitive to the environment, the epigenome is a powerful link and relay between our genes and our surroundings.
