introduction: marginal adaptation is the most critical item in long-term prognosis of single crowns. this study aimed to assess the marginal quality as well asthe discrepancies in marginal integrity of some pfm single crowns of posterior teeth by employing parallel radiography in shiraz dental school, shiraz, iran. methods: in this descriptive study, parallel radiographies were taken from 200 f...

Energy plants are the main source of bioenergy which will play an increasingly important role in future energy supplies. With limited cultivated land resources in China, the development of energy plants may primarily rely on the marginal land. In this study, based on the land use data from 1990 to 2010(every 5 years is a period) and other auxiliary data, the distribution of marginal land suitab...

This study provides an ultrastructural evaluation of cytoplasmic microtubules during the maturation of marginal cells of the mouse stria vascularis. Postnatal marginal cells are cuboidal in structure and over a period of days develop the numerous cellular processes typical of transporting epithelia. Immediately after birth, marginal cells contain numerous microtubules randomly oriented througho...

Marginal zone (MZ) B cells are absent in CD19(-/-) mice. Possible causes include an intrinsic defect in B cells and/or a secondary defect in the extrinsic MZ microenvironment as a result of changes in B cell differentiation in mice lacking CD19. Cells in the MZ also include MZ macrophages (MZM) and MZ dendritic cells (DC). Although CD19 is only expressed on B cells, SIGN-R1(+) MZM are absent an...

Epigenetic mechanisms, including DNA methylation, play an important role in not only the development and maturation of normal cells, but also the development and progression of malignant cells. In this edition of Blood, Arribas et al show that DNA methylation profiling identifies 2 subtypes of splenic marginal zone lymphoma with different clinical and genetic features. These findings provide an...

This paper describes the importance of allowing human-human collaboration in the information-seeking task by modeling the task using Charnov’s Marginal Gain Theorem. Highlighting areas of potential gain, the paper then describes an application that exploits those areas. The application described takes an existing information seeking tool – SolonEvo – and integrates it with a free point-2-point ...

The long tradition of common bean cultivation in Italy has allowed the evolution of many landraces adapted to restricted areas. Nowadays, in response to market demands, old landraces are gradually being replaced by improved cultivars. However, landraces still survive in marginal areas of several Italian regions. Most of them appear severely endangered with risk of extinction due to the advanced...

Somatosensory input to the hypothalamus has been thought to ascend via an indirect, multisynaptic pathway. However, we have antidromically identified nociceptive spinal cord neurons that project directly to the lateral hypothalamus in rats. Retrograde tracers injected into the lateral hypothalamus labeled many spinal neurons bilaterally within the marginal zone, the lateral reticulated area, th...

This study provides a descriptive analysis of human capital in different regions of Pakistan. Three different categories of human capital like rural, urban and overall are formed for the four provinces of Pakistan. The study finds visible difference in human capital situation between rural and urban areas of Pakistan. The study suggests that skills of workforce can be boosted through investment...
