Disseminated superficial actinic porokeratosis (DSAP) is an inherited disorder of keratinization readily diagnosed through clinical and histologic examination. While generally benign in nature, the lesions can have profound psychosocial implications for patients. Although no cure exists, a number of treatment modalities, from topical medications to laser and light devices, have been reported with variable success. The authors report two cases of DSAP treated with the 1927-nm thulium fiber fractional laser along with a review of the treatment literature for DSAP...

BACKGROUND AND OBJECTIVES: A 28-year-old female presented with extensive scarring after a traumatic injury to her right lower extremity. She had been hit by a vehicle one year prior to presentation and had several open fractures with extensive overlying cutaneous damage, which required multiple surgeries and skin grafts. She had limited range of motion of the affected limb secondary to scar contracture. STUDY DESIGN/MATERIALS AND METHODS: The patient received 6 treatments with a non-ablative fractional resurfacing (NAFR) device with two wavelengths (Fraxel DUAL, Solta Medical, Hayward, CA) spaced 4-8 weeks apart...

Bupropion HCl is an atypical antidepressant drug with rapid and high first-pass metabolism. Sustained release dosage form of this drug is suggested for reducing its side effects which are mainly seizures. The aim of the present study was to design pulmonary agar nanospheres of bupropion HCl with effective systemic absorption and extended release properties. Bupropion HCl was encapsulated in agar nanospheres by ionic gelation, and characterized for physical and release properties. Pharmacokinetic studies on nanospheres were performed on rats by intratracheal spraying of 5 mg/kg of drug in form of nanospheres compared to intravenous and pulmonary delivery of the same dose as simple solution of the drug...

Non-ablative fractional laser procedures have become increasingly popular since their introduction in 2004. The fractional 1,927 nm thulium laser is a non-ablative device that penetrates up to 300 μm in the skin and the 1,550 nm erbium:glass laser penetrates up to 1,400 μm. These procedures are considered minimally invasive with a high safety profile; therefore, infectious complications are exceedingly rare. However, we report five recent cases of bacterial infection with both gram-positive and gram-negative organisms following treatment with the fractional 1550/1927 nm laser approximately 1 day to 1 week post-procedure...

We present the first demonstration of a 792 nm diode-pumped Tm3+:LiLuF4 thin-disk laser operation around 1.9 μm. In multimode configuration, up to 21 W of output power and a maximal slope efficiency of 49% with an optical-to-optical efficiency of 40% was demonstrated. A tuning range from 1899 nm to 1927 nm could be achieved by inserting an etalon into the cavity.

We report on monotonically positively chirped pulse operation of a hybridly mode-locked thulium fiber laser. Dispersion management was realized with a small-core, high-NA fiber providing normal dispersion in the 2 μm wavelength region. The laser delivered pulses with 0.7 nJ energy at the 1927 nm center wavelength and sub-500-fs pulse duration after compression.

Despite the fact that ferrous myeloperoxidase (MPO) can bind both O(2) and NO, its ability to bind CO has been questioned. UV/visible spectroscopy was used to confirm that CO induces small spectral shifts in ferrous MPO, and Fourier transform infrared difference spectroscopy showed definitively that these arose from formation of a heme ferrous-CO compound. Recombination rates after CO photolysis were monitored at 618 and 645 nm as a function of CO concentration and pH. At pH 6.3, k(on) and k(off) were 0.14 mM(-1) x s(-1) and 0...

In this work we report the spectroscopy and laser results of several Thulium doped BaY(2)F(8) single crystals grown using the Czochralski technique. The doping concentration is between 2at.% and 18at.%. We performed room temperature laser experiments pumping the samples with a laser diode at 789 nm obtaining 61% as maximum optical-to-optical efficiency with a maximum output power of 290 mW and a minimum lasing threshold of 26 mW. The lasing wavelength changed with the dopant concentration from 1927 nm up to 2030 nm and the nature of the transition changed from purely electronic to vibronic, accordingly...

High-temperature rate constant experiments on OH with the five large (C(5)-C(8)) saturated hydrocarbons n-heptane, 2,2,3,3-tetramethylbutane (2,2,3,3-TMB), n-pentane, n-hexane, and 2,3-dimethylbutane (2,3-DMB) were performed with the reflected-shock-tube technique using multipass absorption spectrometric detection of OH radicals at 308 nm. Single-point determinations at approximately 1200 K on n-heptane, 2,2,3,3-TMB, n-hexane, and 2,3-DMB were previously reported by Cohen and co-workers; however, the present work substantially extends the database to both lower and higher temperature...

Hemeproteins play an important role in the signaling processes mediated by nitric oxide (NO). For example, the production of NO by nitric oxide synthase, the activation of guanylate cyclase by binding NO, and the scavenging of NO by hemoglobin, myoglobin, and cytochrome c oxidase all occur through unique mechanisms of interaction between NO and hemeproteins. Unlike carbon monoxide (CO) and oxygen (O2), which have been studied extensively, the reactions of NO with ferric and ferrous hemeproteins are not as well characterized...

The monoptychic 'apocrine' scent glands of the sternal region of two adult male Tupaia belangeri were studied by transmission and scanning electron microscopy, in order to assess the modes of release of their secretory products. In segments of the secretory tubules with a narrow lumen the epithelial cells are columnar and are firmly connected to each other by desmosomes and junctional complexes. Myoepithelial cells are interspersed between the secretory epithelium and the basement membrane. The cytoplasm of the secretory epithelial cells contains granular and agranular endoplasmic reticulum, mitochondria, Golgi apparatus, lysosomes and secretory granules...
