There are few reports of localized urticaria with symptoms to similar to livedo racemosa (reticularis) in adults. Here we describe a rare case of localized cold urticaria (grade 1) on the face of a 32-yearfemale. The results of an ice cube test showed a positive reaction on the affected area (her cheeks). Treatment with anti-histamine (second generation) tablets, warming and avoidance of cold e...

BACKGROUND AND AIMS Understanding the introduction history of invasive plant species is important for their management and identifying effective host-specific biological control agents. However, uncertain taxonomy, intra- and interspecific hybridization, and cryptic speciation may obscure introduction histories, making it difficult to identify native regions to explore for host-specific agents....

For the first time, we have implemented photoacoustic tomography (PAT) to image the water content of an edema in vivo. We produced and imaged a cold-induced cerebral edema transcranially, then obtained blood vessel and water accumulation images at 610 and 975 nm, respectively. We tracked the changes at 12, 24, and 36 h after the cold injury. The blood volume decreased after the cold injury, and...

tak-ab is a new winter bread wheat cultivar developed from evaluation of icarda-turkey-cimmyt international bread wheat germplasm to supplementary irrigation areas. study of new cultivars under supplementary irrigation in maragheh and ardebil research stations (2005-2012) showed that, tak-ab had high grain potential under supplementary irrigation conditions. based on results means of grain yiel...
