Introduction. Kyphosis is a deformity of the spine characterized by excessive backward curvature thoracic spine. The normal range kyphosis in teenagers 20 - 40 degrees, and diagnosis hyper-kyphosis beyond 45 degrees. aim this review was to assess magnitude effects various corrective exercises on kyphotic angle reduction. Material Methods. Web Science PubMed were searched retrieve relevant liter...

Evaluation of pediatric spinal deformity requires knowledge of special orthopaedic testing and radiographic interpretation. The determination of recommendations for treatment of spinal abnormalities in children can be challenging and at times complex, as treatment options are dependent upon a variety of factors. The etiology of scoliosis or kyphosis, presence or absence of vertebral anomalies, ...

In the Drosophila embryo, Nanos and Pumilio collaborate to repress the translation of hunchback mRNA in the somatic cytoplasm. Both proteins are also required for repression of maternal Cyclin B mRNA in the germline; it has not been clear whether they act directly on Cyclin B mRNA, and if so, whether regulation in the presumptive somatic and germline cytoplasm proceeds by similar or fundamental...

Co-evolution between developmental regulatory elements is an important mechanism of evolution. This work compares the hunchback-bicoid interaction in the housefly Musca domestica with Drosophila melanogaster. The Musca HUNCHBACK protein is 66% conserved and partially rescues a hunchback mutant, yet the BICOID-dependent promoter (P2) of Musca hunchback is unexpectedly diverged from D. melanogast...

 Abstract Background: Correction of severe kyphosis is a challenging operation in spinal surgery. A two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. We describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. Methods: Twelve patients (six male and s...

The gap gene hunchback (hb) is a key regulator in the anteroposterior patterning of insects. Loss-of-function of hb resulted in segmentation defects in the next generation. In this paper, hb expression level was investigated at different developmental stages of the pea aphid, Acyrthosiphon pisum (Ap). Aphb mRNA was most early detected at the first instar stage and showed an incontinuous increas...

Axial patterning is a fundamental event in early development, and molecules involved in determining the body axes provide a coordinate system for subsequent patterning. While orthologs of Drosophila bicoid and nanos play a conserved role in anteroposterior (AP) patterning within at least a subset of Diptera, conservation of this process has not yet been demonstrated outside of the flies. Indeed...

Activation of the gap gene hunchback (hb) by the maternal Bicoid gradient is one of the most intensively studied gene regulatory interactions in animal development. Most efforts to understand this process have focused on the classical Bicoid target enhancer located immediately upstream of the P2 promoter. However, hb is also regulated by a recently identified distal shadow enhancer as well as a...
