Infantile hemangiomas (IHs) are non-malignant, largely cutaneous vascular tumors affecting approximately 5-10% of children to varying degrees. During the first year of life, these tumors are strongly proliferative, reaching an average size ranging from 2 to 20 cm. These lesions subsequently stabilize, undergo a spontaneous slow involution and are fully regressed by 5 to 10 years of age. Systemi...

Lasers, 595-nm pulsed dye and 1,064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG), have been used successfully for the treatment of infantile hemangiomas (IHs). Recently the use of a topical β-blocker, specifically timolol maleate, has been promising in the treatment of IHs. The objective of this study was to compare the effectiveness of topical timolol 5 mg/mL solution with that of combi...

The evolutionary history of the human pygmy phenotype (small body size), a characteristic of African and Southeast Asian rainforest hunter-gatherers, is largely unknown. Here we use a genome-wide admixture mapping analysis to identify 16 genomic regions that are significantly associated with the pygmy phenotype in the Batwa, a rainforest hunter-gatherer population from Uganda (east central Afri...

PURPOSE To compare the pharmacodynamic effects of an anodyne spray (XQAS) containing extracts of two herbs, Cynanchum paniculatum (CP) and Illicium henryi (IH), with those of spray containing the vehicle alone, CP alone (CPS) or IH alone (IHS), when applied topically acute soft tissue injury (STI) in an animal model. METHODS Acute closed STI was modeled by hammer blow in the hind leg muscle o...

A useful technique in various applications of remote sensing involves the fusion of panchromatic and multispectral images. Wavelet-based approaches to image fusion generally produce high-quality spectral content in fused images. However, the spatial resolution obtained by most wavelet-based methods is less than that obtained by the intensity-hue-saturation (IHS) method. Recent studies show that...

Multifocal hepatic hemangioma (MHH) is a benign hepatic tumor that is commonly diagnosed in children with multiple cutaneous infantile hemangiomas (IHs). We present a review of all children with MHH at our institutions. Of the 42 patients, the median age at presentation of MHH was 2.5 months. Thirty-six (85.7%) patients had cutaneous IHs. Twelve (28.6%) patients were symptomatic at presentation...

چکیده: هدف ادغام تصویر، ترکیب دو یا چند تصویر برای رسیدن به یک تصویر واحدی است که نتیجه آن افزایش کیفیت و دقت تفسیر تصاویر است. دستگاه های تصویربرداری عملکردی مانند pet (مقطع نگاری با نشر پوزیترون)، تصاویری با محتوی طیفی بالا اما اطلاعات مکانی پایین تولید می کنند. در مقابل تصاویر حاصل شده توسط دستگاه های تصویربرداری ساختاری همچون mri (تصویربرداری تشدید مغناطیسی)، دقت مکانی خوب و طیفی پایینی دار...
