OBJECTIVE To examine whether narrowband ultraviolet B (NBUVB) phototherapy administration to plaque-type psoriatic patients leads to an improvement in patient's quality of life (QoL). METHODS A total of 95 patients with plaque-type psoriasis were recruited in the Outpatient Dermatology Clinics of Qassim University affiliated hospitals, Buraydah, Kingdom of Saudi Arabia from January to October...
Vitiligo is an acquired depigmenting disorder. To date, there is no predictive model for its response rate to narrowband ultraviolet B (NBUVB) phototherapy. The aim of this study was to investigate the different types of response of patients with non-segmental vitiligo undergoing NBUVB 3 times a week. Many patients who were previously considered non-responders were given the opportunity to cont...
Optical fiber Bragg gratings (FBG) are key devices for optical communication and sensors. FBGs are based on a periodic variation in the refractive index of the fiber core and allow for the reflection of a narrowband signal centered at a specific Bragg wavelength. Over the last two decades, FBGs have been manufactured mainly by modifying the core refractive index using interferometric or point-b...
Exposure to solar ultraviolet B radiation during the summer months is the main source of vitamin D (VD) for people living in northern latitudes. The aim of this study was to determine whether artificial narrowband ultraviolet B (NB-UVB) whole-body exposures could maintain VD levels in winter. The intervention group received 2 standard erythema doses (SEDs) of NB-UVB exposures every second week ...
INTRODUCTION Matrix metalloproteinase-12 (MMP-12) may play an important role in the pathogenesis and spread of psoriatic disease. AIM To investigate plasma levels of the selected enzyme in plaque psoriasis patients before and after the course of narrowband UVB (NBUVB) therapy with respect to disease advancement. MATERIAL AND METHODS The cohort included 49 patients suffering from plaque psor...
BACKGROUND Narrowband UVB (NBUVB) is currently used to treat early mycosis fungoides (MF). There are a number of reports on the efficacy and safety of NBUVB in Caucasians, but little data is available for Asians. OBJECTIVE This study was designed to evaluate the effectiveness and safety of NBUVB for early stage MF in Korean patients. METHODS We enrolled 14 patients (12 men, 2 women; age ran...
The collapse of baryons into the center of a host dark matter halo is accompanied by radiation that may be detectable as compact ( < ∼ 10 kpc) UV-continuum and Lyα emission with Lyα luminosities as high as ∼ 1042 −1043 erg s−1 in halos of mass M = 1011 − 10M⊙. We show that the observed equivalent width (EW) of the Lyα line emitted by these cooling clouds is EW < ∼ 400 Å (restframe). These lumin...
CD93 is involved in angiogenesis and inflammation, both of which are key processes in the pathogenesis of psoriasis. CD93 was studied in serum, peripheral blood mononuclear cells and skin of patients with psoriasis and controls. Furthermore, allele frequencies for CD93 single-nucleotide polymorphisms rs2749812 and rs2749817 were assessed in patients with psoriasis compared with controls and the...
Lichen planus pemphigoides (LPP) is an autoimmune disease characterised by evolution of subepidermal blisters on normal and lichen planus affected skin. We describe a case of LPP in a 54-year-old Chinese woman. The patient presented with psoriasiform plaques and was diagnosed with guttate psoriasis. Narrowband ultraviolet B (NBUVB) therapy was commenced, and she experienced a generalised erupti...
Various applications of lasers to electric propulsion problems have previously been made, and laser techniques are potentially powerful means to address and resolve a range of current issues. Studies with sufficiently high resolution and sensitivity to reveal the fine details of velocity, density, and temperature distributions for trace species will be especially valuable. Continuous narrowband...
