Planarians can be cut into irregularly shaped fragments capable of regenerating new and complete organisms. Such regenerative capacities involve a robust ability to restore bilateral symmetry. We have identified three genes needed for bilaterally asymmetric fragments to regenerate missing body parts. These genes are candidate components of a signaling pathway that controls the dorsal-ventral pa...

The alpha-like globin gene cluster in rabbits contains embryonic zeta-globin genes, an adult alpha-globin gene, and theta-globin genes of undetermined function. The basic arrangement of genes, deduced from analysis of cloned DNA fragments, is 5'-zeta 0-zeta 1-alpha 1-theta 1-zeta 2-zeta 3-theta 2-3'. However, the pattern of restriction fragments containing zeta- and theta-globin genes varies am...

The neural cell adhesion molecule L1 is a multidomain protein that plays important roles in cell adhesion, migration, and neurite outgrowth. To analyze structure-function relationships of L1 in neurite outgrowth and cell body adhesion, we have expressed and purified a set of different fragments of the extracellular part of this glycoprotein in CHO cells and in Escherichia coli. When neurite out...

BACKGROUND The cytologic accuracy in assessing malignancy in papillary breast neoplasms (PBNs) is controversial. This is further complicated by overlapping features observed in other breast lesions that produce papillary-like tissue fragments. METHODS The authors reviewed 22 fine-needle aspirates (FNAs) from histologically proven papillary neoplasms: papillary carcinoma (PCA; 10 aspirates) an...

In Public cloud when it is used for the practical application which is outside the User’s premises, there are several security issues are arising. These can be overcome by the use multi cloud architecture there they are using four kinds of approach like replication of application, partition application system into tiers ,partition of application logic into fragments , partition of data into fra...

We used 22 fragments corresponding to the reverse transcriptase domain of copia-like retrotransposons as representatives to study the organization and distribution of these elements in the rice genome. The loci detected by these 22 fragments were assigned to 47 locations in the molecular-linkage map involving all 12 chromosomes. The distributional features of copia-like retrotransposons found i...

long-term complications of retained war fragments in the body are not completely known. also, bullet migration and slow resorption of metals and distortion in some imaging modalities are frequent and well recognized complications but, now we are concerned about neoplastic changes near the retained war fragments. we reviewed the literature on complication of retained war fragments and report our...
