Management of chronic total occlusions has been refined through the development of a retrograde approach via collateral pathways. We describe here the use of excimer laser coronary atherectomy in the septal collaterals. This appraoch was not yet described in the literature.

Energy transfer has been investigated in polyvinyltoluene (PVT) scintillators containing pyrene, p-terphenyl and naphthalene by measurement of scintillation pulse shapes and yields. It is concluded that there is an initial rapid diffusion of the excitation energy with solute molecules, residual monomer and PVT excimer sites acting as competing traps. At later times energy can transfer from resi...

Active matrix organic light emitting diode (AMOLED) displays are considerably attractive for high brightness, high efficiency and fast response time. Active matrix employing thin Film Transistors (TFTs) allows OLED displays to be larger in size, higher in resolution and lower in power consumption than passive matrix. Especially, low temperature polycrystalline silicon (LTPS) TFT employing excim...

The experimental details of KrF laser “oscillator – amplifier” configuration used in UCSD mirror damage facility are given. Two commercial KrF lasers are used for running oscillator-amplifier mode of operation. The pulses from Compex KrF excimer laser is sliced using a Pockels cell to FWHM 5ns and passed through the LPX excimer cavity for amplification. The experimental details, gain analysis a...

Excimer lasers and high technology instrumentation have ushered in a new era of vision improvement surgery in Hawaii, replacing the more traditional forms of refractive surgery: cataract surgery, corneal transplant surgery, and radial keratotomy. Corneal surgery has been enhanced by new techniques of microsurgery and a more effective tissue procurement system for donor corneal tissue. Several l...

Proper treatment of infectious air could potentially mitigate the spread airborne viruses such as porcine reproductive and respiratory syndrome virus (PRRSV). The objective this research is to test effectiveness ultraviolet (UV) in inactivating aerosolized PRRSV, specifically, four UV lamps, UV-A (365 nm, both fluorescent LED-based), “excimer” UV-C (222 nm), germicidal (254 were tested. two lam...

Photothermal Therapy In article number 2301739, Wenbo Hu and co-workers present an excimer-mediated intermolecular nonradiative (interNR) decay channel to produce a giant photothermal effect for high-efficient in vivo phototheranostics. A deep understanding of the interNR provides novel guidelines developing more advanced organic materials.

Vitiligo is a common and chronic disease with a great impact on patients' quality of life. Phototherapy with narrowband ultraviolet B radiation and excimer laser are two treatment modalities that are used increasingly for the management of the disease with variable results. In this article, we review the efficacy, adverse effects, and possible mechanisms of action of narrowband ultraviolet B an...
