Intracellular electrophysiological recordings were obtained from amacrine and ganglion cells in an isolated,. superfused retinaeyecup preparation of the rabbit. Cells were characterized physiologically, after which cell-staining was accomplished by intracellular iontophoresis of HRP. A computer-assisted image-processing system was used to study the dendritic stratification pattern of HRP-labele...

OBJECTIVE The purpose of this clinical study was to evaluate the effectiveness of an intense pulsed light (IPL) irradiator system for the treatment of benign pigmented lesions. MATERIALS AND METHODS A total of 18 patients with lentigo solaris and eight patients with melanocytic nevi were treated once with an IPL system. After 2 months, the effect was evaluated on close-up photographs. RESUL...

Background: This research explored the efficacy and safety of IPL in treatment dry eye caused by Meibomian gland dysfunction (MGD).

There is a clear association between dry eye disease (DED) and skin inflammatory diseases occurring in close proximity to the eyelids, such as facial skin rosacea. Intense pulsed light (IPL) is widely accepted as a treatment for skin rosacea. A number of recent studies demonstrated that, in patients suffering from meibomian gland dysfunction (MGD), IPL therapy also reduces signs and symptoms of...

Background: Different treatment modalities are used for the treatment and aesthetic improvement of aging hands. This study evaluated the efficacy and safety of a novel technology, which combines bipolar radiofrequency (RF) and optical energies for the cosmetic treatment of aging hands. Objective: To assess the efficacy, safety, tolerability and patient satisfaction of combined bipolar radiofreq...

BACKGROUND Intense pulsed light (IPL) has a well-recognized role in the treatment of photodamaged skin. OBJECTIVE To assess the safety and efficacy of a novel single-band IPL handpiece versus dual-band IPL handpiece in the treatment of photodamage. STUDY DESIGN/MATERIALS AND METHODS This was a prospective, single-center split-face study with 20 enrolled participants. Three treatments, 21 da...

Binding sites for [3H]muscimol, an analogue of gamma-aminobutyric acid (GABA) were localized in the synaptic layers of chicken retina by light microscopic and electron microscopic autoradiography. Light microscopic autoradiography of cryostat sections incubated in [3H]muscimol or [3H]GABA revealed identical binding patterns: a band over the inner plexiform layer (IPL) and a band over the outer ...

Genes with restricted expression within the developing embryo represent valuable tools as they allow distinct tissue types to be distinguished and studied. In order to identify genes that are expressed within a particular germ layer, a differential screen was performed using germ layer-specific cDNA libraries derived from gastrulation stage mouse embryos. The gene expression profiles of the ger...

The human cortical visual system is organized into major pathways: a dorsal stream projecting to the superior parietal lobe (SPL), considered to be critical for visuospatial perception or on-line control of visually guided movements, and a ventral stream leading to the inferotemporal cortex, mediating object perception. Between these structures lies a large region, consisting of the inferior pa...
